FACILITY DESCRIPTION This section provides a general description of the Hazardous Waste Management Facility (HWMF). This description is intended to acquaint the permit application reviewer and permit writer with a general overview of the HWMF. More detailed descriptions can be found in other parts of this permit application. B-1 GENERAL DESCRIPTION The Badin Business Park, formerly known as ("f/k/a") the Alcoa-Badin Works and hereinafter known as the "facility", is located on approximately 123 acres of land off Highway 740 in Badin, Stanly County, North Carolina. The USGS location (shown on Figure B-l) is 80° 07’ 05" West longitude and 35° 24' 32'' North latitude. The facility is a former primary aluminum smelting plant. The facility began producing aluminum at Badin in 1916 after purchasing and completing the holdings of a French combine, which had begun work on a smelter. The facility consisted of two potlines; an electrode plant where anodes and cathodes were manufactured; casting facilities for producing aluminum specialty ingot products, super-purity metal, coiled sheet, and mold line ingots; a machine shop; and various offices and utility buildings. Aluminum production was curtailed in August 2002. The plant continued to manufacture anodes and high-purity aluminum until 2007. The plant was permanently closed in 2010. Since closing the plant in 2010, the former plant site has been redeveloped into a business park for manufacturing companies. Prior to closure, the facility generated approximately 2,700 tons per year of Spent Potlining from the production of aluminum metal. EPA considers Spent Potlining a hazardous waste which may pose a substantial present or potential hazard to human health or the environment when improperly transported, treated, stored, disposed or otherwise managed. The HWMF previously contained two Hazardous Waste Management Units (Buildings 206 North and 206 South) for Spent Potlining waste (K088). Building 206 North was operated as a containment building, while Building 206 South was operated as a container storage building. Buildings 206 North and 206 South were closed in July 2012. Since closure of the plant and the two Hazardous Waste Management Units, the facility does not regularly generate hazardous waste and the facility does not contain any operational units where hazardous waste is (or will be) treated, stored, or disposed. One existing unit, Building 044, is designated as a less than 90-day hazardous waste storage area and does not require permitting. B-2 TOPOGRAPHIC MAP B-2a General Requirements Figure B-2 is a Topographic Map showing the facility boundaries, buildings, and other details. B-2a (1) 100-Year Floodplain As described in Section B-4b of this permit application, the facility is not located in a 100-year floodplain. A copy of the 100-year flood plain map has been included as Appendix B-l. BADIN BUSINESS PARK Part B Permit Application Original: February 19, 2016 Revision 2: June 20, 2018 B-2 B-2a (2) Surface Waters Narrows Reservoir (Badin Lake), Little Mountain Creek, and an unnamed intermittent surface water feature are known to exist within 1,000 ft. of the facility. B-2a (3) Surrounding Land Uses Figure B-3 shows present zoning designations based on zoning maps provided by the Stanly County Planning and Zoning Department. The facility property is zoned M-2. The M-2 designation is for heavy industry. Figure B-3 is dated March 6, 2007. Recent observations confirm that present land use around the facility property corresponds to the present surrounding land zoning designations. The property is bordered generally to the east by single-family residential and business areas, to the west by single- family residential districts, to the south by both residential and undeveloped areas, and to the north by undeveloped land and recreational areas bordering Narrows Reservoir (Badin Lake). B-2a (4) Wind Rose Figure B-4 shows an annual wind rose of meteorological data obtained from Albemarle monitoring station KVUJ 121835Z from February 12, 2015, to February 12, 2016. This station is the closest known station to the facility. B-2a (5) Location of Hazardous Waste Units and Legal Boundaries Since closure of the plant, the facility does not regularly generate hazardous waste and the facility does not contain any operational units where hazardous waste is (or will be) treated, stored, or disposed. One existing unit, Building 044, is designated as a less than 90-day hazardous waste storage area and does not require permitting. B-2a (6) Fire Control Facilities The locations of the four active fire hydrants at the facility are illustrated on Figure B-5. The Badin Volunteer Fire Department is located across NC 740 from the facility and has a 2012 Spartan Gladiator/Custom Fire Pumper-Tanker, a 2003 Spartan Gladiator/ 4 Guys Engine and a 1989 Mack/ 4 Guys fire engine. B-2a (7) Sewers. Run-off Control Systems, Flood Control and Injection and Withdrawal Wells Figure B-6 and B-7 detail the physical layout of storm and sanitary sewers, respectively at the plant. The storm sewer system is largely responsible for run-off and flood control. As discussed earlier and detailed later in this application, the facility is not located in a 100-ycar floodplain nor is it subject to frequent flooding. The plant has no on-site or off-site injection wells or withdrawal wells. BADIN BUSINESS PARK Part B Permit Application Original: February 19, 2016 Revision 2: June 20, 2018 B-3 B-2 (8) Location of Access Control. Access and Internal Roads, and Loading and Unloading Areas Figure B-8 shows the facility and locations of access control, access and internal roads, and associated loading and unloading areas. Former process areas of the plant are bordered entirely by an 8-foot high wire fence with one controlled access gate. Access control and other security features and procedures are discussed in further detail in Subsection F-la(1) (24-Hour Surveillance System). B-2a (9) Location of Solid Waste Management Units A list of known on-site and off-site Solid Waste Management Units (SWMUs) and Areas of Concern (AOCs) at the facility is included in Table B-1. Figure B-9 shows the location of the SWMUs and AOCs requiring corrective action. B-2b Additional Topographic Requirements for Land Storage, Treatment and Disposal Facilities As discussed in Subsection E, the facility supports its claim for an exemption from ground water monitoring requirements pertaining to the facility; therefore, additional topographic requirements do not apply. B-3 TRAFFIC INFORMATION B-3a Estimated Volume Since closure of the plant, the facility does not regularly generate hazardous waste and the facility does not contain any operational units where a hazardous waste permit is (or will be) required. One existing unit, Building 044, is designated as a less than 90-day hazardous waste storage area and does not require permitting. B-3b Traffic Pattern As shown in Figure B-8, a vehicle receiving drummed waste from the less than 90-day hazardous waste storage area enters the facility from the main guard gate at the eastern perimeter of the plant. The truck then proceeds north 0.2 miles to Building 044. After loading, the truck completes the same route in the opposite direction to return to a truck parking area near the main guardhouse. After designated facility personnel approve manifests and associated paperwork, the truck is allowed to exit to Highway 740 through the main gate. B-3c Traffic Control Various company vehicles and fork trucks travel roadways throughout the facility. Private vehicles belonging to visitors may also occupy the main routes identified in Figure B-8. Traffic is controlled by posted stop signs and speed limit signs, flashing caution lights at heavy use intersections, and pedestrian walkways. The plant speed limit (15 MPH) is liberally posted and strictly enforced. BADIN BUSINESS PARK Part B Permit Application Original: February 19, 2016 Revision 2: June 20, 2018 B-4 B-3d Access Road(s) Surfacing and Load-Bearing Capacity Most roads within the plant are asphalt paved or concrete. Access roadways are frequently inspected, maintained and, when necessary, repaired. Plant roads have demonstrated sufficient load bearing capacity in many years of service with only minor maintenance. The roadways have carried the full weight of any anticipated traffic loads. The load bearing capacity of the majority of the roads is 3,000 pounds per square feet (PSF) (minimum). The PSF value is based on a firm to stiff clay. The interpretation is based on geotechnical boring logs and standard penetration tests performed when the borings were being completed. B-4 LOCATION INFORMATION B-4a Seismic Considerations Because the facility is an existing rather than a new facility, seismic considerations do not apply. In any case, the facility is not located in any of the political jurisdictions specified in Part 264, Appendix VI. B-4b Floodplain Standard According to the applicable Flood Insurance Rate Map, the facility is not located within a 100-year floodplain. Therefore, the floodplain standard and corresponding subsections in the permit application guidance do not apply. The Flood Insurance Rate Map (FIRM) which addresses the facility location is provided in Appendix B-l. B-4c Additional North Carolina Location Standards All facilities require at least a 0.25-mile separation distance from institutions such as schools, hospitals and prisons. Existing facilities “shall require to meet these distances to the maximum extent feasible”. The closest identified institution to the site is Badin School located over 0.25 miles southeast of the facility. The location of the school has been illustrated on Figure B-l. Building 044 is located over 50 feet from the property boundary. Ignitable, incompatible, and reactive wastes are not stored at the facility.

GROUNDWATER MONITORING Under the March 24, 2006, Hazardous Waste Management Permit, the former Building 206 North containment building and former Building 206 South container storage area were identified as non-land- based units and qualified for groundwater monitoring exemptions under 40 CFR 264.90(b)(2)(i)(ii)(iii). Therefore, groundwater monitoring requirements were not applicable to these units and that permit application. Since the issuance of that permit and the closure of the plant, the facility does not regularly generate hazardous waste and the facility does not contain any operational units where hazardous waste is (or will be) treated, stored, or disposed. One existing unit, Building 044, is designated as a less than 90-day hazardous waste storage area and does not require permitting. Groundwater monitoring to be conducted under any presumptive remedy will be determined after approval of the Corrective Measures Study. BADIN BUSINESS PARK Part B Permit Application Original: February 19, 2016 Revision 2: June 20, 2018 F-1 F. PROCEDURES TO PREVENT HAZARDS F-1 SECURITY F-1a Security Procedures and Equipment As a primary means of security protection and in lieu of security procedures and equipment specific to the facility, access to the facility is controlled 24 hours a day, 365 days a year. F-1a(1) 24-Hour Surveillance System As described in Subsection F-1a(2) (Barrier and Means to Control Entry), the facility uses an 8-foot fence to control access to the facility. Therefore, the requirements of this subsection do not apply to the permit application. F-1a(2) Barrier and Means to Control Entry Per §264.14(b)(2), an 8-foot high chain link fence equipped with barbed wire serves as an artificial barrier which completely surrounds the former main plant area. The three entrances to the former main plant area include the main, construction and shipping gates located at the eastern, western and southern perimeters of the site, respectively. Main entry to the former main plant area is from Highway 740 through the main gate. Access to the main entry is restricted to authorized personnel by remote controlled gate during business hours only, five days per week. Outside of those hours, the main gate is closed and locked. The construction gate and shipping gates are closed and locked at all times, except when in use. Offsite solid waste management unit SWMU No. 2 (Alcoa/Badin Landfill) is surrounded by an 8-foot high chain link fence equipped with barbed wire serving as an artificial barrier. The two entrances to SWMU No. 2 include the main entry and lower access gates located at the northern and southwestern perimeters of the site, respectively. Access to the main entry is restricted to authorized personnel by key during business hours only, five days per week. Outside of those hours, the main gate is closed and locked. The lower access gate is closed and locked at all times, except when in use. Offsite solid waste management units SWMU No. 3 (Old Brick Landfill) and SWMU No. 44 (Pine Grove Area) are inactive portions of the facility which were not operated after the effective date of Part 261. The remaining identified solid waste management units outside the former main plant area fence boundary, SWMU Nos. 19, 25 through 31, 41, and 45, either required no further action or no further investigation. F-1a(3) Warning Signs A rectangular, 12-inch by 10-inch warning sign labeled “DANGER- Unauthorized Personnel KEEP OUT” is clearly posted at each of the entrances to the facility and to Building 044 (Less than 90 storage facility, non-permitted). The sign consists of “DANGER” in 3-inch white letters encircled on a red reflective background on glossy black, “Unauthorized Personnel” in 1/5-inch black letters on glossy black background, and 2-inch “KEEP OUT” letters on glossy black background. A “NO SMOKING” sign is posted with each warning sign located at the facility and Building 044. Each sign can be seen BADIN BUSINESS PARK Part B Permit Application Original: February 19, 2016 Revision 2: June 20, 2018 F-2 from any approach to the facility and is easily legible from a distance of at least 25 feet. The sign legend is in English- the language used predominately in the area. F-1b Waiver The facility does not request a waiver of security procedures and equipment requirements; therefore, the requirements of this subsection do not apply. F-2 INSPECTION SCHEDULE F-2a General Inspection Requirements The facility conducts regular inspections of their less than 90-day storage facility (Building 044), for irregularities that could lead to a release of hazardous constituents and adversely affect human health or the environment. Specific items inspected and the established protocol and schedule for their inspection are described in Subsections F-2a(1) (Types of Problems), F-2a(2)(Frequency of Inspection), and F- 2c(1) (Container Inspection). As required by 40 CFR 264.15(b)(2), a copy of the facility inspection schedule is kept at the facility at all times. F-2a(1) Types of Problems Problems pertaining to the facility which may be anticipated, and therefore require routine inspection, include the following:  evidence of tampering of the waste or containers, or other evidence of unauthorized access to the facility;  damage to the physical structure of or attachments to the facility, including roof, walls, floor, doors, hazard warning signs, lighting systems, and emergency equipment;  damage to the access roads, ramps and runways to the facility;  evidence of inadequate stormwater runoff from the facility;  evidence of spills around the facility or the placement of waste in unauthorized locations; and  blockage of facility ventilation structures. F-2(a)2 Frequency of Inspection Building 044 is inspected according to the frequencies and procedures described in the “Release Prevention, Control and Countermeasure Plan (RPCC Plan) for the facility (August 2013). When hazardous wastes are stored at the facility, each item on the inspection schedule and checklists described in Subsection F-2c(1) (Container Inspection) is inspected at least every seven days. Some items are inspected more frequently. Within one (1) working day following an intense storm where a failure of the containment system might have occurred, all items on the checklist are inspected regardless of the time of their last inspection. BADIN BUSINESS PARK Part B Permit Application Original: February 19, 2016 Revision 2: June 20, 2018 F-3 F-2b Facility Inspection Requirements Specific items to be inspected include the following:  emergency and safety equipment;  testing, as necessary, of communication systems (telephone, hand-held two-way radios);  availability of personnel protective equipment (respirator cartridges, coveralls, gloves, etc.);  availability of spill control materials and equipment (brooms, shovels, rags, etc.); and  security devices (warning signs, security lighting). The equipment listed above will be tested as necessary. F-2c Specific Process Inspection Requirements F-2c(1) Container Inspection Described below are items that will be routinely inspected, if present at the facility. As discussed in Subsection F-2a(2) (Frequency of Inspection), all items are inspected at least every seven days and within one working day following a storm or other intense weather event, as long as the item is present at the facility. Each inspection includes an evaluation of the following: 1. all containers labeled with the words “Hazardous Waste” and start accumulation date; 2. all containers closed; 3. no evidence of leaking containers; and 4. no evidence of deterioration of containers or the concrete floor. F-2c(2) Building Inspection Currently, hazardous waste stored less than 90 days on-site is located in Building 044. Building 044 is a non-permitted building due to the storage time.

F-3 WAIVER OF PREPAREDNESS AND PREVENTION REQUIREMENTS The facility does not request a waiver of the preparedness and prevention requirements of 40 CFR 264, Subpart C. F-3a Equipment Requirements Emergency equipment, including the communication equipment, spill control equipment, personnel protection equipment, and decontamination equipment, is kept in the guard house (Building 009), the non-permitted short-term storage building (Building 044), Building 134R, and Building 205D. Specifically, the emergency equipment includes a plant telephone, spill booms and absorbent; respirator cartridges, gloves and coveralls; and brooms, shovels, rags and other miscellaneous cleanup equipment. F-3a(1) Internal Communications Radio Base stations are maintained at the Guard House (Building 009). Employees may use hand-held radio transmitters/receivers to communicate by voice with key plant personnel including the First Aid Attendant and in-plant emergency contacts (see Subsection G-2). Emergency assistance may also be obtained by calling Extension 777 using the intra-plant telephone system. Evacuation of the facility is initiated by an announcement over the plant-wide intercom system. F-3a(2) External Communications Personnel may contact in-plant or outside emergency personnel via the radio system described above or the plant telephone system. Personnel in need of emergency assistance may contact the First Aid Attendant, Emergency Coordinator or other key emergency contact via either hand-held radio or intra- BADIN BUSINESS PARK Part B Permit Application Original: February 19, 2016 Revision 2: June 20, 2018 F-6 plant telephone (Ext. 777) or by dialing 911. If necessary, the emergency contact can then summon outside assistance via normal telephone channels. F-3a(3) Emergency Equipment The facility maintains fire control, spill control and decontamination equipment at select areas around the facility. Emergency equipment and procedures are addressed in the Contingency Plan (Section G). F-3a(4) Water for Fire Control As discussed in the Contingency Plan (Section G), the facility maintains automatic sprinkler systems, fire hydrants, and fire extinguishers as necessary throughout the facility. Because of its close proximity to the facility, the Badin Volunteer Fire Department has primary authority to respond to fire emergencies at the plant. The City of Albemarle, North Caroline Fire Department will provide additional support upon request of the Badin Volunteer Fire Department. F-3b Aisle Space Requirement Sufficient aisle space is maintained in buildings to allow the unobstructed movement of personnel, fire protection equipment, spill control equipment, and decontamination equipment. F-4 PREVENTIVE PROCEDURES, STRUCTURES, AND EQUIPMENT F-4a Unloading Operations Spent potlining is no longer present at the facility. The unloading operations for hazardous waste were located at Building 206, which has since been demolished and no longer exists. Therefore, this section does not apply to the facility. F-4b Run-Off Hazardous wastes will only be stored in fully-enclosed structures. Therefore, run-off from these buildings is not anticipated. The concrete foundation retaining walls of each building provide primary flood control (run-on). Additional flood control is provided by the plant-wide storm water drain system, located in the concrete runway leading to each building. As documented in subsection B-4b (floodplain Standard), the buildings are not located in a 100-year floodplain. F-4c Water Supplies The closest drinking water supply is Narrows Reservoir (Badin Lake) located approximately one-quarter mile downgradient. The construction and design of the buildings and their distance from Narrows Reservoir together greatly minimize the potential for contamination of water supplies. The intake from Badin Lake is located several miles upstream from the facility. BADIN BUSINESS PARK Part B Permit Application Original: February 19, 2016 Revision 2: June 20, 2018 F-7 F-4d Equipment and Power Failure A power failure would not significantly affect the operation of any container storage areas. Electrical power is required only for providing security and work lighting for the buildings. Auxiliary generator power is available at the plant if needed to provide emergency lighting. F-4e Personnel Protection Equipment Standard protective equipment for personnel involved in the direct management of hazardous waste includes steel-toed boots/shoes with metatarsal guards, safety glasses, hard hat, disposable coveralls, gloves, and a respirator. Use of the protective equipment is addressed in the Personnel Training Program, which satisfies the Occupational Safety and Health Standards of 29 CFR Part 1910, Subpart I- Personal Protective Equipment. F-4f Ventilation Equipment Passive ventilation structures are present in any buildings to aid in control of fugitive dust emissions. F-5 PREVENTION OF REACTION OF IGNITABLE, REACTIVE, AND INCOMPATIBLE WASTES The facility does not manage ignitable, reactive, or incompatible wastes at the facility, therefore the requirements of this subsection do not apply.

OTHER FEDERAL LAWS This section is submitted to demonstrate compliance with the following Federal laws. J-1 WILD AND SCENIC RIVERS ACT This act has established a national policy of dam and other construction at appropriate sections of the rivers of the United States that would preserve other selected rivers or section of rivers in their free- flowing condition to protect the water quality of such rivers and fulfill other vital national conservation purposes. A list of rivers and/or sections of rivers has been designated as components of the national wild and scenic river system under Section 2 (ii) of this act. The Yadkin River, located near the site, is not included on this list. Therefore this act does not apply to the site. J-2 NATIONAL HISTORIC PRESERVATION ACT OF 1966 The purpose of this act is to preserve the prehistoric and historic resources of the United States. Title I Section 101 (a)(1)(A-B) of this act identify two lists: the National Register of Historic Places and the list of Natural Historic Landmarks. Inclusion on either of these lists triggers the requirements of this act. The site is not listed on either the National Register of Historic Places or the list of Natural Historic Landmarks. Therefore, this act does not apply at the site. J-3 ENDANGERED SPECIES ACT This act provides a program for the conservation of threatened and endangered plants and animals and the habitats in which they are found. This act authorizes the determination and listing of species as endangered and threatened. Currently there are 61 species (35 animal and 26 plant species) in the state of North Carolina listed on the endangered and threatened species list. No critical habitats of endangered or threatened species are present at the site. Therefore, this act does not apply to the site. J-4 COASTAL ZONE MANAGEMENT ACT This act established a voluntary national program within the Department of Commerce to encourage coastal States to develop and implement coastal zone management plans. These plans are required to include a defined coastal zone boundary. Prompted by this act, the 1974 North Carolina General Assembly passed the Coastal Area Management Act, known as CAMA. CAMA identified 20 coastal counties that are regulated under the Act. This site is not located within one of these counties. Therefore, this act does not apply to the site. J-5 FISH AND WILDLIFE COORDINATION ACT This act requires that the Regional Administrator, before issuing a permit proposing or authorizing impoundment (with certain exemptions), diversion, or other control or modification of any body of water, consult with the appropriate State agency exercising jurisdiction over wildlife resources to conserve those resources. No water bodies are located on the site. Therefore, this act does not apply to the site. BADIN BUSINESS PARK Part B Permit Application Original: February 19, 2016 Revision 2: June 20, 2018 K.

INFORMATION REQUIRED FOR SOLID WASTE MANAGEMENT UNITS The facility was issued a Hazardous Waste Management Permit to store spent potlining on March 30, 1992 and the permit was renewed on March 24, 2006. The Hazardous Waste Management Permit required the identification and investigation of solid waste management units (SWMU) and areas of concern (AOC) for potential adverse impact to the environmental media at the facility. A total of forty-nine SWMUs and AOCs have been identified at the facility. The RCRA Facility Assessment (RFA) Report includes information for SWMU Nos. 1 through 34 and AOCs A and B. Information for SWMU Nos. 35 through 47 was provided in subsequent correspondence to the Agency. As part of the RFA and subsequent processes, no further action (NFA) was immediately determined for twenty-two solid waste management units, Confirmatory Sampling (CS) was conducted at five units in which no further investigation (NFI) was warranted, NFI was determined for two units, eighteen units were investigated further under the RCRA Facility Investigation process, and two storage units were to be permitted. Both storage units regulated by the RCRA Permit were closed. Correspondence demonstrating acceptance of closure by the Agency is provided in Appendix L-1. The results of the extensive investigation were evaluated and summarized in the March 1990 RFA Report, June 1993 Confirmatory Sampling Report, and March 2001 RCRA Facility Investigation (RFI) Report. The RFI Report was approved by NCDENR on December 19, 2007. With the approval of the RFI Report, the Corrective Measures Study (CMS) process was initiated to identify and evaluate remedial alternatives to determine effective and efficient technologies to remediate identified contaminated media. Phase 4 of the CMS identified and evaluated the alternatives for corrective action and Phase 5 of the CMS provided the justification and recommendation of the selected alternatives for the remedy of the facility. Both reports are currently under review by NCDEQ. As a result of the investigations, interim measures (IM), and remedial actions conducted, NFA or NFI has been granted for all or a portion of forty three SWMUs. The two permitted storage units were cleaned closed. A portion of nine SWMUs including the groundwater at the Main Plant Area, groundwater at the Alcoa-Badin Landfill, and groundwater at the Old Brick Landfill were carried forward to the CMS. A SWMU/AOC summary table is provided below. Table L-1 SWMU/AOC Summary Table SWMU/ AOC Number SWMU/AOC Name Current Status Date Determined 1 On-Site Landfill RFI recommended NFA/CMS1 03/2001 2 Alcoa-Badin Landfill RFI recommended CMS 03/2001 3 Old Brick Landfill RFI recommended CMS 03/2001 1 In accordance with NCDENR’s letter to Alcoa dated September 9, 1999 and the approved RFI Work Plan, SWMUs in the North End were addressed in the RFI using the “SWMU-Area Concept”, whereby SWMUs were grouped together based on commonalities. Groundwater for all the SWMUs in the North End (SWMU Nos. 1, 4, 22, 25, 33, 35, and 44) were addressed using the SWMU-Area concept because the SWMUs are all located within a contiguous infilled valley and having the same COIs. Further, the COIs in groundwater are not traceable to any individual SWMU. As detailed in the approved RFI report, no further action was recommended for soil for these units.

In the February 22, 2012, Certification of Closure report, the “K088 Storage Building 206 – South” is referred to as SWMU 5. Both units are closed permitted units. 3 On February 9, 1993, the NCDEHNR approved the deletion of SWMUs 10, 12, 13, 34, 37, and 40. SWMU 10 was combined with SWMU 7, and SWMUs 12, 13, 34, 37, and 40 were combined with SWMU 11. 4 As detailed in the approved RFI report, no further action was recommended for SWMUs 11 and 46 except for inclusion of nearby groundwater monitoring wells in a periodic monitoring program. 5 In the March 1990 RFA, SWMU 27 is listed as “Underground Conveyance Line to NPDES Outfall 003”. In the March 1992 Hazardous Waste Management Permit, SWMU 27 is listed as the “Underground Conveyance Line to NPDES Outfall 001”. Where discrepancies exist, the listing in the Permit was given precedence. 6 In the March 1990 RFA, SWMU 28 is listed as “Underground Conveyance Line to NPDES Outfall 002”. In the March 1992 Hazardous Waste Management Permit, SWMU 28 is listed as the “Underground Conveyance Line to NPDES Outfall 003”.

The RFI report identified groundwater in three areas of the facility as needing further actions. These areas were: groundwater at the Alcoa/Badin Landfill (“SWMU No. 2”); groundwater at the Old Brick Landfill (“SWMU No. 3”); and groundwater at the Main Plant. Groundwater at the Main Plant utilizes a North End SWMU Area approach addressing groundwater at SWMU Nos. 1, 4, 22, 25, 33, 35 and 44. These SWMUs were addressed jointly because they are all located within the same contiguous infilled valley, have the same COIs, and releases to groundwater are not traceable to any individual SWMU. As recommended in the approved RFI report, groundwater monitoring wells in proximity to SWMU Nos. 11 and 46 are to be included a periodic monitoring program. L-1a Solid Waste Management Units and Areas of Concern The following paragraphs provide descriptions of each identified SWMU that was retained as needing further actions. 7 On May 17, 2017, the Badin Business Park LLC requested that SWMU 41 be regulated solely under the authority of the facility’s RCRA permit as SWMU 41 rather than under the Inactive Hazardous Sites Branch (IHSB) as Alcoa-Pine Rd Ravine Disposal site (NONCD0001177). This request was made because the IHSB site NONCD0001177 and SWMU 41 are in fact one in the same. On February 16, 2018, NCDEQ determined that SWMU 41 should remain under the authority of the IHSB. 8 Per Section L-1a of the October 11, 2001 Part B RCRA Hazardous Waste Permit Application, the area of contaminated soils was removed in 1996. Post removal soil samples did not contain detectable concentrations of the constituent of concern and the area was subsequently paved over. BADIN BUSINESS PARK Part B Permit Application Original: February 19, 2016 Revision 2: June 20, 2018 L-4 L-1a (1) SWMU No. 2 (Alcoa/Badin Landfill) The following information was provided in previous submittals: Type of unit: Municipal Solid Waste and Alcoa Plant Waste Landfill Dimensions of the unit: Approximate area of 8 acres Dates of operation of the unit: Early 1900s to mid-1970s Specification of all wastes that have been managed at the unit: Municipal solid waste, facility solid waste, baghouse carbon dust, asbestos, potential of spent potlining waste (K088). Current Description: The Alcoa/Badin Landfill was used as an unlined municipal/industrial solid-waste landfill. This unit was positioned within a natural ravine located southeast of Wood St. extending to the east. Municipal refuse, process material, and native fill material were used to fill the natural ravine approximately 13 to 42 feet to the current grade. In 1997, interim measures were completed at the landfill consisting of re-grading and cover improvements of two additional feet of low-permeability clay and six inches of topsoil to establish a vegetative cover. The objectives of the interim measures were to prevent surface run-on, promote surface run-off, and reduce infiltration into the landfill. Additionally, voluntary monitoring of seeps identified at the base of the landfill was initiated. Historic analytical data suggested the seeps discharge water passed through the landfill. In June 2000, construction of a low-flow seep collection system was completed combining the three seeps into a single discharge under the facility's NPDES permit. In 2005, the discharge was eliminated through the installation of a force main to route the seep water to a utility sewer that leads to a Stanly County Utilities Publicly Owned Treatment Works (POTW). In 2015, NCDENR, now NCDEQ, directed the collection of samples along Little Mountain Creek near the Alcoa/Badin Landfill to determine if constituents of concern may be leaching from the Alcoa/Badin Landfill into nearby Little Mountain Creek, the results of which are discussed in Section L-1c. In June 2016, NCDEQ issued a Site Inspection Report for the Alcoa/Badin Landfill which concluded that the site warranted further evaluation. Multiple fill and hydrogeological assessments have been performed between 2009 and 2015 to better understand the landfill and seep areas. The assessments suggest a complex hydrological relation exists. Based on the information obtained from the fill and hydrogeological assessments, the facility opted to replace the previously existing three individual seep collection points with a trench-based seep collection system and install a slurry barrier wall system down gradient of the collection trench. The upgrade to a trench system is expected to improve overall system capture and collection efficiency by intercepting water below grade immediately down gradient of the landfill. The slurry barrier is expected to further enhance the capability of the system by mitigating water migration to the Little Mountain Creek floodplain. In April 2017, a work plan was submitted to the NCDEQ with an objective to provide evidence that the recent upgrade activities are functioning. In addition, the results will be used to develop a subsequent work plan regarding an evaluation of the long-term effectiveness of recent upgrade activities completed at the Alcoa/Badin Landfill. BADIN BUSINESS PARK Part B Permit Application Original: February 19, 2016 Revision 2: June 20, 2018 L-5 L-1a (2) SWMU No. 3 Old Brick Landfill Type of unit: Alcoa Plant Waste Landfill Dimensions of the unit: Approximate area of 10-15 acres Dates of operation of the unit: 1915 to 1960 Specification of all wastes that have been managed at the unit: Used baking furnace brick and the potential of spent potlining waste (K088). Current Description: The Old Brick Landfill was used from 1915 to 1960 as a disposal site for waste originating from aluminum smelting operations. Approximately 22,000 cubic yards of waste were estimated to have been disposed in the landfill. In 1987, the fill area was covered with 12 inches of compacted clay, and a ditch was constructed on the upslope side to divert stormwater. Since 1987, voluntary activities were conducted to minimize infiltration of surface waters into the landfill. These activities included the 1996 improvements, a diversion channel to route surface water run-on around the landfill and the 1997 landslide and cover repairs. In 2007, a new cover and storm water management system was installed as a maintenance activity to eliminate routine discharges from NPDES Outfall 019. The new cover and storm water management system eliminates contact between storm water and water infiltration from landfill waste materials. This was done by first removing toe drains from the landfill. These toe drains were a conduit for infiltrated water in contact with waste materials to seep at the surface. Secondly, improvements were made to the cover system to eliminate water contact with waste materials. The new cover system improvements consisted of four basic components; 1) revised landfill surface profile to promote surface drainage, 2) installation of a Re-compacted Soil Barrier (RSB) and flexible membrane liner (FML) to eliminate water infiltration, 3) installation of a high-flow geo-composite drainage system to remove water infiltration through the landfill area, and 4) soil and vegetative cover system to shed, absorb, and evapotranspirate storm water. The new SWMU No. 3 soil and vegetative cover has some storage capacity to absorb and evapotranspirate rainfall. Rainfall beyond the storage capacity of the cover is designed to either run-off through surface channels or drain through the underlying synthetic lined drainage system to a new diffuser toe-drain. A storm water retention pond has been added to collect these flows. The retention pond was constructed to allow percolation and evapotranspiration of the collected storm water. The pond is designed to hold the 25-year/24-hour storm event. L-1a (3) North End SWMU Area Groundwater at the Main Plant utilizes a North End SWMU Area approach addressing groundwater at SWMU Nos. 1, 4, 22, 25, 33, 35, 44, and 46. L-1a (3)(A) SWMU No. 1 On-Site Landfill Type of unit: Smelting Process Waste Landfill Dimensions of the unit: Approximately 2 acres Dates of operation of the unit: Circa 1930s to late 1970s BADIN BUSINESS PARK Part B Permit Application Original: February 19, 2016 Revision 2: June 20, 2018 L-6 Specification of all wastes that have been managed at the unit: Potential of spent potlining waste (K088) Current Description: The On-Site Landfill is located in the northwestern portion of the facility and occupies approximately two acres. From the 1930’s to 1970’s, fill materials, including spent potliner (SPL), were periodically placed in a natural easterly trending ravine that traversed the area. After ceasing this practice, the area was graded and the Wet Weather Run-on Diversion (SWMU No. 33) was installed. In 1996, voluntary interim measures were implemented concurrently at SWMU No. 1, SWMU No. 4, and SWMU No. 33. All work was conducted in accordance with an Interim Measures Work Plan that was approved by the Department. Interim measures consisted of surface water control improvements to bring the discharge of permitted NPDES Outfall 013 into compliance with the total cyanide limit of 46 ug/l established by the NCDEHNR Division of Water Quality. These activities were designed to be supportive of long-term corrective action objectives for all three SWMUs, primarily by stabilizing the On-Site Landfill through cover improvements and removal of the Wet Weather Run-on Diversion from the landfill. Interim measures also consisted of raising and relocating SWMU No. 33 (Wet Weather Run-on Diversion) wet storm water pipes and ditches outside the areas suspected to contain SPL and at elevations above the groundwater table. Open ditches were replaced with sealed-joint concrete pipe. A minimum two feet thick, low permeability soil cover was placed over SWMU No. 1 (On-Site Landfill) and SWMU No. 4 (Former K088 Storage Pad). The surface of the entire SWMU Group 1 area is vegetated with grasses that are regularly mowed as part of landfill operation and maintenance (O&M) activities. L-1a (3)(B) SWMU No. 4 Former K088 Storage Pad Type of unit: On-Grade Concrete Storage Pad for K088 Storage Dimensions of the unit: Estimated to be 400 feet by 60 feet Dates of operation of the unit: 1915 - 1981 Specification of all wastes that have been managed at the unit: Potential of spent potlining waste (K088) Current Description: SWMU No. 4, (Former K088 Storage Pad) was located just north of Building 058 near SWMU No. 1. the pad was used from 1915 to 1981 to store SPL prior to constructing Building 058. The pad was constructed of concrete and measured approximately 280 by 60 feet. The pad was reportedly weathered, and soils that underlie the pad were exposed in some places beneath the weathered concrete. Recent activities are further detailed under Section L-1a (3)(A) SWMU No. 1 On-Site Landfill. L-1a (3)(C) SWMU No. 22 Scrap Yard Type of unit: Scrap Storage Area Dimensions of the unit: 400 x 90 foot (largest dimensions) wedge shaped area Dates of operation of the unit: 1915 to 1994 Specification of all wastes that have been managed at the unit: Steel scrap, wood, piping, carbon dust, miscellaneous scrap. BADIN BUSINESS PARK Part B Permit Application Original: February 19, 2016 Revision 2: June 20, 2018 L-7 Current Description: Between 1915 and 1994, this approximately 400 x 90 foot (largest dimensions) wedge shaped area at the north end of the facility was used to store miscellaneous wooden and metals scrap. Prior to soil removal work in 1994, the area exhibited stained surface soils. Materials or contaminant sources in SWMU No. 22 (Scrap Yard) potentially included SPL, metal scrap, carbon dust, equipment with PCB containing oils, miscellaneous oils and solvents, asbestos, refractory materials, alumina, electrolytic bath, and anode butts. In August 1994, voluntary measures were implemented at SWMU No. 22. The voluntary measures included removing surface and subsurface debris, and soil from the SWMU. Materials were excavated to depths ranging from 6-inches to 4.5 feet. The removed and excavated materials and soil, totaling 725 tons, were manifested to the RCRA Subtitle C permitted Landfill in Emelle, Alabama. Verification samples were obtained after the soil removal. Clean soil was imported to backfill deeper parts of the excavation. A 30-mil HDPE liner was placed over the backfill, and the area was covered with #57 washed stone. The soil removal documentation was provided to the Department on November 3, 1994. In 2016, best management practices were implemented at SWMU No. 22 and the surrounding area in support of the facility’s NPDES permit. Best management practices included the cleaning of storm sewers, the excavation and disposal of surface soils, and the backfilling of excavated areas with compacted soil and a gravel cover. All best management practices were intended to limit the potential discharge of fluoride from the Outfall. L-1a (3)(D) SWMU No. 25 Underground Conveyance Line to NPDES Outfall 009 Type of unit: Underground Pipeline Dimensions of the unit: Approximately 1,050 linear feet Dates of operation of the unit: Circa 1915 – 1991 Specification of all wastes that have been managed at the unit: Stormwater runoff from the northern end of the facility. Current Description: SWMU No. 25 underground piping extends from Badin Lake westward into the northern end of the Badin Business Park facility. The Underground Conveyance Line to NPDES Outfall 009 (North Storm Drain) discharged non-contact cooling water and, in some cases, stormwater runoff from the North End of the facility into Badin Lake. The outfall was renamed Outfall 012 and includes Outfall 011 which discharges stormwater during wet weather when it exceeds the capacity of a diffuser associated with Outfall 012. The underground conveyance line was never used to store or manage wastes. However, prior to repair and replacement work done to it in 1991, it may have acted as a conduit for the inflow and infiltration of impacted groundwater beneath SWMUs. Groundwater was able to infiltrate the North Storm Drain because it was buried beneath the groundwater table in the area and the concrete pipe was damaged in several places, as determined from a video survey. On April 16, 1990, a Special Order by Consent (SOC) agreement was entered into with the North Carolina Division of Environmental Management (NCDEM). The SOC included a series of activities and timetables to bring the effluent at (formerly named) Outfall 009 into compliance with the effluent BADIN BUSINESS PARK Part B Permit Application Original: February 19, 2016 Revision 2: June 20, 2018 L-8 limitations of the facility’s NPDES permit. One of the activities was the repair and replacement of the North Storm Drain piping. The pipe repair consisted of relocating and raising sections of the conveyance line above the groundwater table, replacing the sections with sealed joint pipe, and removing or sealing abandoned sections of pipe. The NCDEM was notified of compliance with the requirements of the SOC in a letter dated December 6, 1991. In addition, slip lining of a section of the conveyance system was performed in 1997 to further mitigate the potential for this SWMU to act as a conduit for groundwater migration to Badin Lake. L-1a (3)(E) SWMU No. 33 Wet-Weather Run-On Diversion Type of unit: Stormwater Diversion Structure Dimensions of the unit: Approximately 300 linear feet Dates of operation of the unit: Circa 1970s to Present Specification of all wastes that have been managed at the unit: Stormwater run-off. Current Description: SWMU No. 33 (Wet Weather Run-on Diversion) consisted of an underground concrete pipe, which traversed the On-Site Landfill (SWMU No. 1). The pipe was installed to divert off-site seepage (spring) water, and on-site and off-site stormwater runoff to Badin Lake. Recent activities are further detailed under Section L-1a (3)(A) SWMU No. 1 On-Site Landfill. L-1a (3)(F) SWMU No. 35 Former Waste Oil Storage Area Type of unit: Waste Oil Storage Area - Drums Dimensions of the unit: Triangular in shape and measures approximately 110 feet by 50 feet Dates of operation of the unit: Circa 1920s to 1970 Specification of all wastes that have been managed at the unit: Motor oil, hydraulic oil, process lubricants, solvents, and transformer oils Current Description: The area now identified as SWMU 35 was used from the 1920’s to the early 1970’s to store containers of various waste motor oils, lubricating oils, and transformer oils that possibly contained polychlorinated biphenyls (PCBs). The area is triangular in shape and measures approximately 110 feet by 50 feet (largest dimensions). A fill assessment was conducted at SWMU 35 in support of an interim measure remedial effort for PCB impacted soils within this unit. The investigation results for this assessment was presented in the SWMU 35 CMS Engineering Investigation Summary Report, dated August 31, 2011. Results of the fill assessment were used in the development of the SWMU 35 PCB Removal Interim Measures Work Plan approved by NCDENR and USEPA on May 7, 2012. A choice was made to remediate the PCB impacted areas to a cleanup level of ≤1 mg/kg to allow for a potential unrestricted use for the property. In August 2012, PCB impacted soils were excavated and transported off site for disposal. Analytical results from soil samples collected from the SWMU No. 35 excavation side walls and bottom confirm that no concentrations of PCBs are present above the cleanup level of ≤1 mg/kg set forth in the Work Plan. BADIN BUSINESS PARK Part B Permit Application Original: February 19, 2016 Revision 2: June 20, 2018 L-9 L-1a (3)(G) SWMU No. 44 Pine Tree Grove Area Type of unit: Filled-in embayment of Badin Lake Dimensions of the unit: Approximately 200 feet wide by 450 feet long Dates of operation of the unit: Progressively filled over time, starting between 1938 and 1951, and ending between 1959 and 1961 Specification of all wastes that have been managed at the unit: Plant waste and fill material. Based on CMS results, it is unlikely that hazardous waste was managed in the unit. Current Description: The Pine Tree Grove Area is located in the North End of the Badin facility adjacent to Badin Lake and outside of the plant’s fenced area. The North End is characterized by a natural west-east trending valley (Northwest Valley) that was progressively filled during the period between 1916 and 1968. The Pine Tree Grove Area, located at the eastern end of the valley, is a former pond that was connected to Badin Lake. Filling of the Pine Tree Grove Area was completed between 1959 and 1961 and contents of the fill material are varied (i.e., decaying organic material, mulch, and wood debris; sand, silt, and clay soils; construction debris including gravel, concrete, brick, and rock fragments; aluminum scrap; and granular carbonaceous material). As part of the CMS, a fill assessment was conducted at the Pine Tree Grove Area by evaluating the recent geophysical survey, installing soil borings in and around the unit, and comparing early 20th century topographic maps and photographs with current topographic maps of the area. The assessment confirmed that fill materials are most prevalent in the north end of the plant, where they were used to infill an eastward trending natural ravine. The variety of materials used in the filling of the ravine resulted in a complex stratigraphic sequence of natural and anthropogenic origin. This fill material serves as a more permeable conduit for horizontal groundwater and constituent migration, and influences the groundwater plume geometry. L-1a (3)(H) SWMU No. 46 Coke Management Area (f/k/a West SPL Area) Type of unit: Filled-in area on west side of plant Dimensions of the unit: Up to 100 feet wide by 200 feet long Dates of operation of the unit: Between March 1964 and April 1977 Specification of all wastes that have been managed at the unit: Plant waste and fill material. Based on CMS results, it is unlikely that SPL was managed in the unit. Current Description: As part of a review of historical photographs during the RFI, this area was identified as a fill area with the potential of receiving SPL. Based on the photographs, filling activities are believed to have started after March 1964 and ended before April 1977. A February 1968 photograph shows evidence of activity in the area. Although not included in the RFI Work Plan, it was decided to subject this area to RFI activities to assess the potential for SPL and determine whether it warranted inclusion as a SWMU. The West SPL Area was added as a SWMU in September 1999 with a notification to the Department. During the CMS, a review of historical topographic maps, historical photographs, aerial imagery and recent Site investigative activities confirmed that SWMU No. 46 is a fill area related to plant expansion and modernization activities. This recent data supported a morphology consisting of native fill soils and BADIN BUSINESS PARK Part B Permit Application Original: February 19, 2016 Revision 2: June 20, 2018 L-10 minor amounts of plant process remnants used to raise the area to its existing grade, or approximately 10 to 20 feet. These incidental plant process remnants may contribute to the groundwater 2L exceedance observed in the well located at the SWMU No. 46 (MW-29). Since more detailed plant expansion and modernization morphology of the SWMU No. 46 area has been developed, a more appropriate designation for the SWMU No. 46 is "Coke Management Area". L-1b Information Pertaining to Releases The RCRA Facility Assessment (RFA) Report has been previously completed by EPA Region IV. Since then, the former Alcoa-Badin Works facility identified and reported new SWMUs; completed activities and reported the results of Confirmatory Sampling (CS); completed activities and reported the results of the RCRA Facility Investigation (RFI); completed Interim Measures at selected SWMUs; and completed the Corrective Measures Study (CMS). The CMS is currently pending approval by the Agency. L-1b (1) Confirmatory Sampling Confirmatory Sampling was conducted in 1993 in accordance with an approved CS Workplan. The results were submitted to EPA Region IV in a CS Report dated June 28, 1993. Copies of the CS Workplan and CS Report were also submitted to the NCDENR. Based on the results, EPA Region IV determined, based on a letter dated January 11,1994 that four SWMUs and one AOC be retained for an RFI, no further action was required for four SWMUs. L-1b (2) RCRA Facility Investigation The facility's Part B Permit included an original requirement for an RFI at six SWMUs and one AOC. In their letter dated January 11, 1994 EPA Region IV required an RFI for four existing SWMUs and one AOC based on the CS results, and for two newly reported SWMUs. An initial RFI Workplan was prepared for these twelve SWMUs and two AOCs. The RFI Workplan was submitted to the NCDENR on April 11, 1994. In response to comments received from the NCDENR dated May 30, 1995 revisions to the RFI Workplan were submitted on October 26, 1995. In response to additional comments received from the NCDENR on July 2, 1998, revisions to the RFI Workplan were submitted on October 30, 1998. The RFI Workplan was approved by NCDENR in a letter dated February 10, 1999. Two new SWMUs were added to the RFI activities after the approval of the Workplan. Phase I RFI activities were conducted in September-October 1999. The results identified the need for Phase II RFI Activities. A Phase II RFI was prepared and submitted to NCDENR on April 11, 2000. The Phase II RFI Workplan was approved by NCDENR in a letter dated June 27, 2000. RFI Phase II activities were completed in August-September 2000. The RFI Report containing the results of the Phase I and II activities was submitted to NCDENR on April 6, 2001. The RFI Report section on RFI Summary, Conclusions and Recommendations is contained in Appendix L-2. L-1b (3) Corrective Measures Study BADIN BUSINESS PARK Part B Permit Application Original: February 19, 2016 Revision 2: June 20, 2018 L-11 Part VII of the facility’s RCRA permit outlined the corrective action activities to be conducted. The RFI report identified groundwater in three areas of the facility as needing further actions. These areas were: groundwater at the Alcoa/Badin Landfill (“SWMU No. 2”); groundwater at the Old Brick Landfill (“SWMU No. 3”); and groundwater at the Main Plant. Groundwater at the Main Plant utilizes a North End SWMU Area approach addressing groundwater at SWMU Nos. 1, 4, 22, 25, 33, 35 and 44. These SWMUs were addressed jointly because they are all located within the same contiguous infilled valley, have the same COIs, and releases to groundwater are not traceable to any individual SWMU. The development of the CMS was conducted in five phases that included: • Phase 1: Update of Site Geological and Hydrological Model and Establishment of Corrective Action Objectives, submitted to the NCDENR as the Corrective Measures Study - Phase 1 Report in August 2009, • Phase 2: Identification and Development of the Corrective Measures Alternatives, submitted to the NCDENR as the Phase 2 Identification of Potential Treatment Technologies Report on October 21, 2009, • Phase 3: Engineering Data Collection, submitted to the NCDENR as the Phase 3 Engineering Data Collection for the Corrective Measures Study Report on October 31, 2012, • Phase 4: Refine Corrective Measures Alternatives, submitted to the NCDENR as the Phase 4 Corrective Measures Alternatives and Phase 5 Justification and Recommendation of the Selected Corrective Measure Alternative for the Corrective Measures Study Report on January 24, 2013, and • Phase 5: Justification and Recommendation of the Selected Corrective Measure Alternative submitted to the NCDENR in conjunction with the Phase 4 Report on January 24, 2013. The Phase 4 and Phase 5 CMS Report utilized the results from Phase 3 to analyze corrective measures alternatives identified in Phase 2 against evaluation criteria outlined in Phase 1. A copy of the site conditions from the Phase 4 and Phase 5 CMS Report has been included as Appendix L-3. The CMS is currently pending approval by the Agency. L-1c Sampling and Analysis L-1c (1) SWMU No. 2 (Alcoa/Badin Landfill) The RFI results showed no Constituents of Interest (“COIs”) present in soil adjacent to the Alcoa/Badin Landfill at concentrations exceeding the conservative risk-based screening values. As a result, soils surrounding SWMU No. 2 do not pose unacceptable risk to current or reasonably anticipated future receptors. However, the RFI did show one constituent in groundwater exceeding the screening value in a single well down gradient of the landfill. This constituent was total cyanide. A screening level risk assessment was conducted on the first receptor for groundwater down gradient of the landfill. This receptor is Little Mountain Creek and it showed that no COIs are present at concentrations exceeding applicable human health screening values. The unit was retained in the Corrective Action process because of the detection of total cyanide in one groundwater well above the regulatory standard. BADIN BUSINESS PARK Part B Permit Application Original: February 19, 2016 Revision 2: June 20, 2018 L-12 CMS Phase 3 groundwater sampling results demonstrate the beneficial effects of landfill cover system upgrades. In results from all the recent sampling events, available cyanide and fluoride were not reported in any well at concentrations that exceed the NC 2L Standard. In 2015, the NCDENR directed the collection of environmental samples along Little Mountain Creek near the Alcoa/Badin Landfill to determine if constituents of concern may be leaching from the Alcoa/Badin Landfill into nearby Little Mountain Creek. Laboratory analytical results indicated concentrations of cyanide and metals were detected in sediment samples above laboratory detection limits including the background sediment sample. No concentrations of fluoride, PCBs, VOCs, and SVOCs were detected in any sediment sample from Little Mountain Creek. Laboratory analytical results indicated concentrations of total cyanide and two metals (barium and chromium) were detected in surface water samples above laboratory detection limits including the background surface water sample. All concentrations were below the 15A NCAC 02B Surface Water Standards. No concentrations of fluoride, PCBs, VOCs, and SVOCs were detected in any surface water sample from Little Mountain Creek. Laboratory analytical results indicated concentrations of fluoride, cyanide, metals, one VOC (methylene chloride), and selected SVOCs were detected in surficial soil samples above laboratory detection limits. No concentrations of PCBs were detected in any surficial soil samples. Per guidance from US EPA, certain organic chemicals (considered by EPA to be acetone, 2-butanone, methylene chloride, toluene, and the phthalate esters) are designated as common laboratory contaminants. Laboratory analytical results indicated concentrations of fluoride, total cyanide, and metals were detected surface water samples above laboratory detection limits. No concentrations of PCBs, VOCs, and SVOCs were detected in any surface water samples. Laboratory analytical results indicated concentrations of fluoride, metals, one VOC (acetone) and one SVOC (bis(2-ethylhexyl)phthalate) were detected in groundwater samples above laboratory detection limits. No concentrations of available cyanide or PCBs were detected in any groundwater samples. Acetone and bis(2-ethylhexyl)phthalate are common laboratory contaminants. As described above, NCDEQ issued a Site Inspection Report for the Alcoa/Badin Landfill in June 2016. The Site Inspection Report detailed analytical results from split samples collected during the 2015 environmental sample collection activities. The Site Inspection Report concluded that while sampling identified concentrations of SVOCs, fluoride, and cyanide between the landfill seepage collections and the creek, “SI and contractor sampling from Little Mountain Creek itself produced ambiguous results, making it unclear whether contaminants were discharging to the creek at the time of the SI.” The Site Inspection Report recommended further evaluation, which will be covered under the above referenced April 2017, work plan submitted to the NCDEQ. L-1c (2) SWMU No. 3 Old Brick Landfill The 2001 RFI report demonstrated that there were no COIs present in soils adjacent to the Old Brick Landfill at concentrations exceeding the conservative risk-based screening values. As a result, soils do not present a risk. The RFI results did show groundwater in a few wells contained total cyanide that BADIN BUSINESS PARK Part B Permit Application Original: February 19, 2016 Revision 2: June 20, 2018 L-13 exceeded the screening values. The unit was retained in the Corrective Action process because of the detection of total cyanide in selected groundwater wells above the regulatory standard. The Old Brick Landfill cover system was upgraded in 2006 to eliminate point source discharges to surface water under facility’s NPDES Permit. This upgrade consisted of cover system reconfiguration to mitigate surface water infiltration, control storm water flow, and manage storm water run-off through infiltration or controlled discharge under the NPDES permit. CMS Phase 3 groundwater sampling results demonstrate the beneficial effects of the cover system upgrades. Available Cyanide was reported above the NC 2L Standard in one well during one of the sampling events. In the subsequent sampling events the compound was not detected at concentrations above the 2L standard in any of the wells. In results from all the recent sampling events, fluoride was not reported in any well at concentrations that exceed the NC 2L Standard. L-1c (3) North End SWMU Area Interim measures activities were conducted at a number of SWMUs within the main plant to address residual surface soil impacts prior to the RFI. The subsequent RFI demonstrated that COI impacted soils were addressed by the interim measures work and soil removal activities. No further action was required to address direct contact pathways for soils at the SWMUs and AOCs in the plant area. However, the RFI did identify cyanide, fluoride, arsenic, trichloroethene and trichloromethane (chloroform) as the only constituents of concern in groundwater along the northeast side of the main plant. A further site wide investigation of groundwater was conducted to characterize fluoride and total cyanide impacts in 2005 and 2006. During this investigation, several new groundwater wells were installed at the facility. In February 2005 and February 2006, groundwater samples were collected from new and a number of existing monitoring wells at the facility. Results of this investigation indicated groundwater flow occurs in the Northwest Valley along two axes to the northeast and the east. Primary direction of groundwater flow is to the east and the lesser flow is to the northeast. Fluoride and cyanide distribution in groundwater shows flow is preferential in those directions. Groundwater within the northern Main Plant area was retained in the Corrective Action process as a result of the RFI and subsequent groundwater investigation. The primary COIs for groundwater are free cyanide and fluoride. CMS Phase 3 groundwater sampling results identified available cyanide, fluoride, and trichloroethene at concentrations above the 2L Standard. Trichloromethane was not detected at a concentration above the 2L standard during the Phase 3 investigation in any well sampled.

The RFI provided the data needed to effectively characterize the nature and extent of COIs detected in the media of interest at each of the SWMUs and AOCs. Media investigated during the RFI included soil, groundwater, surface water, sediment, and landfill gas. The site physical conditions (e.g., geology and hydrogeology) were characterized to understand the potential COI transport mechanisms. A conservative risk-based screening approach was used to evaluate analytical data and focus the RFI on COIs found at concentrations potentially posing risk to human health. As appropriate, the risk assessment of the SWMUs and AOCs focused on potential human exposure scenarios because the Badin Works is an active industrial facility occupied by plant operations and/or areas that undergo routine operation and maintenance activities (e.g., mowing of landfill areas). In addition to the media on the plant property (i.e., soil and groundwater), the risk assessment included an evaluation of human health for off-property surface water and sediment in Badin Lake and Little Mountain Creek. A site-specific risk assessment was conducted for those SWMUs/AOCs where COIs exceeded the screening values. The site-specific risk assessment assumed current and future land use at the facility is industrial, but also included an evaluation of off-site residential areas and Badin Lake. Following is a summary of the major findings for the plant area, SWMU No. 2 (Alcoa/Badin Landfill), and SWMU No. 3 (Old Brick Landfill). 5.1.1 Plant Area RFI SWMUs/AOCs in the plant area include SWMU Nos. 1, 4, 11 22, 25, 33, 35, 38, 42, 44 and 46 and AOCs –A and –B (Figure 1-4, Table 1-1). SWMUs in the north end of the plant (North End) include SWMU Nos. 1, 4, 22, 25, 33, 35, and 44. In accordance with NCDENR’s letter to Alcoa dated September 9, 1999 and the approved RFI Work Plan, SWMUs in the North End are addressed using the “SWMU-Area Concept”, whereby SWMUs are grouped together based on commonalities. J:\Projects\Alcoa\Badin\120006.1E\Reports2001\RFIRpt_March2001.doc 122 Alcoa Badin, NC Works RFI Report March 2001 Groundwater for all the SWMUs in the North End (SWMU Nos. 1, 4, 22, 25, 33, 35, and 44) is addressed using the SWMU-Area concept because the SWMUs are all located within a contiguous infilled valley, have the same COIs, and the COIs in groundwater are not traceable to any individual SWMU. Groundwater beneath the SWMUs and AOCs in the central and southern portion of the plant (SWMU Nos. 11, 38, 42, and 46, and AOCs-A and –B), and off-site landfills (SWMU Nos. 2 and 3) is addressed on an individual SWMU and AOC basis. SWMU Nos. 1, 4, and 33 are grouped into “SWMU Group 1” for the purpose of evaluating soils based on the results of the RFI and Interim Measures (IMs) Work. These SWMUs were grouped together based on similar COIs and proximity to one another. The soil evaluation for each of the remaining SWMUs is evaluated individually. The major findings of the RFI in the plant area are: • The primary COIs identified in soil by the screening level risk assessment are total and free (weak acid dissociable) cyanide, fluoride, PAHs and PCBs. Based on the interim measures work previously performed and the risk assessment, these COIs do not present a direct contact risk to potential receptors under current and reasonably anticipated future land use. The emplacement of a low permeability cap as an interim measure at SWMU Group 1 (SWMU Nos. 1, 4, and 33) has eliminated the potential for contact by workers with the constituents detected in SWMU Group 1 soil. Also, the cap eliminates any potential concerns for off-site contact with SWMU Group 1 soil because the cap eliminates the potential for soil to be eroded and transported off-site by wind or water. As a result, soils at this SWMU Group do not present a concern with respect to direct contact by workers or residents. Alcoa has a program in place to inspect and maintain the cap on a semi-annual basis. The RFI verified the effectiveness of soil removal activities previously conducted by Alcoa at SWMU No. 22, AOC-A, and AOC-B. RFI analytical data show no constituents in SWMU No. 22 soil detected at concentrations exceeding the direct contact risk-based screening values or background concentrations, verifying the effectiveness of the 1994 soil removal activities at this SWMU. RFI samples collected at AOC-B show no constituents detected at concentrations greater than the applicable direct contact screening values (residential and industrial RBCs for surface soils and industrial RBCs for subsurface soil). These results verify the effectiveness of the soil removal action conducted at AOC-B in 1996. The effectiveness of AOC-A soil removal performed in 1985 was verified through historic monitoring and RFI groundwater samples at AOC-A that show no constituents detected. The screening level risk assessment for SWMU No. 43 shows no constituents detected at concentrations exceeding the risk screening levels. SWMU Nos. 11, 35, 44, and 46 each had constituents detected at concentrations exceeding the conservative risk screening values and therefore were subjected to site-specific risk assessments. The site-specific risk assessments J:\Projects\Alcoa\Badin\120006.1E\Reports2001\RFIRpt_March2001.doc 123 Alcoa Badin, NC Works RFI Report March 2001 for each SWMU found direct contact risks at these SWMUs to be within or below USEPA’s acceptable range. As a result of the interim measures work and soil removal activities, and based on the RFI risk assessment, no further action is required to address direct contact pathways for soils at the SWMUs and AOCs in the plant area. • The screening level risk assessment indicated that SWMU Group 1 (SWMU Nos. 1, 4, and 33), SWMU Nos. 11, 35, 44, and 46 and AOC-B contain constituents at concentrations exceeding the conservative screening values used to evaluate the soil to groundwater leaching pathway. The cap placed as an interim measure at SWMU Group 1 addresses the leaching from soil to groundwater at SWMU Nos. 1, 4, and 33. Many of the constituents identified (e.g., PAHs) are eliminated as COIs for the soil to groundwater leaching pathway because they were not detected in site groundwater. • COIs identified in plant groundwater by the screening level risk assessment are total and free (weak acid dissociable and microdiffusion) cyanide, fluoride, arsenic, trichloroethene, and trichloromethane (chloroform). LNAPL was found in a single monitoring at SWMU No. 42 trapped within the immediate area of the Building 016 foundation; however, there were no dissolved phase LNAPL constituents found in groundwater immediately downgradient of SWMU No 42, confirming the limited extent of the LNAPL. Groundwater beneath the plant area is not used for any purpose and there is no direct exposure potential with groundwater to the plant workers or local residents. Alcoa owns the land from the plant to Badin Lake to the east. Therefore, Alcoa can ensure that no drinking water wells will be installed between the SWMUs/AOCs and Badin Lake. A residential well survey determined that nearly all residences are connected to the Stanly County potable supply. While there are few residences with home wells, these homes are hydraulically upgradient of the plant area. Based on the RFI findings, there is no risk to current or potential groundwater users from COIs in groundwater. • Groundwater beneath the plant area flows toward and discharges to Badin Lake. As a result, Badin Lake represents the only potential complete exposure pathway to the COIs in groundwater. The groundwater velocity is relatively slow beneath the plant area (average of 1 ft/day). Therefore, the groundwater discharge rate from the plant area to the Lake is low and plant area groundwater provides only a minor contribution to this large volume lake. The risk-based screening of surface water samples in Badin Lake shows plant area groundwater COIs are not present in the Lake at levels exceeding human health surface water screening values. A human health screening level risk assessment of Badin Lake sediments identified PCBs and PAHs as potential COIs and as a result a site-specific human health risk assessment was performed. The site-specific risk assessment for Badin Lake sediments concluded that areas where sediments can be contacted by human receptors are limited (e.g., the swimming cove or boat launch area), and that potential risks to COIs in this area are within acceptable limits. 5.1.2 SWMU No. 2 (Alcoa/Badin Landfill) • This SWMU was subjected to an interim measure (regrading and capping) to minimize the amount of precipitation infiltration and leaching of Landfill COIs. The cap also eliminates J:\Projects\Alcoa\Badin\120006.1E\Reports2001\RFIRpt_March2001.doc 124 Alcoa Badin, NC Works RFI Report March 2001 the potential for direct contact with the landfill materials. • The screening level risk assessment for soil shows there are no COIs present in soil adjacent to the landfill at concentrations exceeding the conservative risk-based screening values. As a result, soils surrounding SWMU No. 2 do not pose unacceptable risk to potential current or reasonably anticipated future receptors. • The screening level risk assessment for groundwater shows only total cyanide exceeding the screening values, in a single well downgradient of the landfill. Groundwater beneath the landfill is not used for any purpose. There is a residential groundwater well on the opposite side of Little Mountain Creek, at an approximate distance of 0.3 miles to the south. However, groundwater elevation data from triple piezometers at this SWMU show Little Mountain Creek acts as a hydraulic barrier and as a result, groundwater containing COIs does not flow under the creek. The groundwater velocity beneath the Alcoa Badin Landfill is relatively slow (average of about 0.2 ft/day) and as a result the rate of groundwater discharge to Little Mountain Creek is minor. Also, the concentration of free cyanide (i.e., weak acid dissociable and microdiffusion) in SWMU No. 2 monitoring wells does not exceed the screening value. The MCL and NC 2L Standard for cyanide are based on the RfD for free cyanide. As a result, the total cyanide detection in the single well at concentrations slightly above the screening value does not warrant further evaluation. • Seeps containing low levels of cyanide and fluoride manifest at the base of the landfill. Alcoa has constructed a seep collection system and applied for an NPDES permit for seep discharge to Little Mountain Creek. As a result, there is no further action necessary to address seep discharge. • The screening level risk assessment for Little Mountain Creek shows no COIs present at concentrations exceeding applicable human health screening values. 5.2 SWMU No. 3 (Old Brick Landfill) • This SWMU was subjected to an interim measure (regrading and capping) to minimize the amount of precipitation infiltration and leaching of landfill COIs. The cap also eliminates the potential for direct contact with the landfill materials. • The screening level risk assessment for soil shows there are no COIs present adjacent to the landfill at concentrations exceeding the conservative risk-based screening values. As a result, soils do not present a risk to potential current or reasonably anticipated future receptors. • The screening level risk assessment for groundwater shows only total and free cyanide exceeding the screening values. Groundwater beneath the landfill is not used for any purpose. Residential wells identified in the survey are on the other side of Badin Lake and hydraulically isolated from SWMU No. 3. • Groundwater beneath this SWMU flows toward and discharges to Badin Lake. As a result, Badin Lake surface water and sediment represents the only potential complete exposure pathway to the COIs in groundwater. The groundwater velocity is relatively slow beneath the landfill area (average of about 4 ft/day). As a result of this low velocity, groundwater discharge to the Lake is minor. The risk-based screening of surface water and sediment J:\Projects\Alcoa\Badin\120006.1E\Reports2001\RFIRpt_March2001.doc 125 Alcoa Badin, NC Works RFI Report March 2001 samples in Badin Lake shows Old Brick Landfill COIs are not present in the lake at levels exceeding the risk screening values. 5.3 Conclusions and Recommendations The next step in the RCRA Corrective Action process for sites where remediation is warranted would be to evaluate potential remedial alternatives in a Corrective Measures Study (CMS). The purpose of the remediation would be based on the need to satisfy one or more remedial goals. The corrective action goals for the Alcoa Badin Works would be to perform remediation on media with contaminants at concentrations posing unacceptable risk to human health and/or the environment, where appropriate. The RFI has established that no unacceptable risks currently exist due to constituents at the Badin Works SWMUs and AOCs under current and reasonably anticipated future land use. Therefore no remediation is warranted, and accordingly a CMS is not necessary at this time to address the media at the SWMUs. Alcoa is recommending that a groundwater monitoring plan be developed to monitor the natural attenuation of those constituents found at concentrations greater than MCLs or NC 2L Standards. BADIN BUSINESS PARK Part B Permit Application Original: February 19, 2016 Revision 2: June 20, 2018 APPENDIX L-3 EXCERPT FROM JANUARY 2013 CMS REPORT ENVIRONEERING, INC. CMS– Phase 4&5 – Alcoa-Badin Works Facility - Badin, NC; January 2013 4 2.0 SITE CONDITIONS This section describes the conditions at the site, including the Site history, Site conceptual model, and constituents of interest. 2.1 Site History In March 1990, Alcoa filed a RCRA Part B permit application with USEPA to store spent potlining (“SPL”) waste (K088) on-site in an enclosed storage building for greater than 90 days. In response to the permit application, USEPA Region IV performed a RCRA Facility Assessment (“RFA”) of the Alcoa Badin Works and associated off-site locations. The RFA identified at total of 34 SWMUs and 2 Areas of Concern (“AOCs”). Twelve additional SWMUs were added after the initial RFA was completed. The North Carolina Department of Environment, Health, and Natural Resources Division of Solid Waste Management (now the NCDENR Division of Waste Management), in cooperation with USEPA Region IV, issued the final RCRA Part-B Permit to Alcoa on March 30, 1992. Part VII of Alcoa’s RCRA permit outlined the corrective action activities to be conducted. The initial step in the process required that confirmatory sampling be conducted at seven SWMUs. Based on the results of the RFA and the confirmatory sampling a RCRA Facility Investigation (“RFI”) was conducted at 16 SWMUs and AOCs. The RFI Report was submitted to the NCDENR in March 2001. Since the commencement of corrective action activities, twenty-two of the facility’s SWMUs have received “No Further Actions” status by the NCDENR. In addition, Interim Measures activities have been conducted at a number of the Badin SWMUs. The RFI report identified groundwater in three areas of the facility as needing further actions. These areas were: groundwater at the Alcoa/Badin Landfill (“SWMU No. 2”); groundwater at the Old Brick Landfill (“SWMU No. 3”); and groundwater at the Main Plant. 2.2 Site Conceptual Model An understanding of the Site geology, hydrogeology, and Site Conceptual Model is presented in the Corrective Measures Study - Phase 1 Report, submitted to the NCDENR in August 2009. The understanding was updated in the Phase 3 Engineering Data Collection for the Corrective Measures Study Report, submitted to the NCDENR on October 31, 2012. 2.3 Constituents of Interest ("COIs") 2.3.1 Alcoa/Badin Landfill (“SWMU No. 2”) The RFI showed there were no Constituents of Interest (“COIs”) present in soil adjacent to the Alcoa/Badin Landfill at concentrations exceeding the conservative risk-based screening values. The Alcoa/Badin Landfill has a cover drainage system consisting of clean compacted fill overlying the unit. As a result, soils surrounding SWMU No. 2 do not pose unacceptable risk to potential current or reasonably anticipated future receptors. The RFI showed only total cyanide exceeding the screening ENVIRONEERING, INC. CMS– Phase 4&5 – Alcoa-Badin Works Facility - Badin, NC; January 2013 5 values, in a single well downgradient of the landfill. The screening level risk assessment for Little Mountain Creek showed no COIs present at concentrations exceeding applicable human health screening values. The RFI concluded that total cyanide exceeded the screening value in a single well downgradient of the landfill. Phase 3 groundwater sampling results demonstrate the beneficial effects of landfill cover system upgrades. In results from all the recent sampling events, available cyanide and fluoride were not reported in any well at concentrations that exceed the NC 2L Standard. 2.3.2 Old Brick Landfill (“SWMU No. 3”) The RFI showed there were no COIs present in soils adjacent to the Old Brick Landfill at concentrations exceeding the conservative risk-based screening values. The Old Brick Landfill has a cover drainage system consisting of clean compacted fill overlying the unit. As a result, soils do not present a risk to potential current or reasonably anticipated future receptors. The RFI concluded that groundwater showed only cyanide exceeding the screening values. Groundwater beneath the landfill is not used for any purpose. Residential wells identified in the survey are on the other side of Badin Lake and hydraulically isolated from SWMU No. 3. Phase 3 groundwater sampling results demonstrate the beneficial effects of the cover system upgrades. Available Cyanide was reported above the NC 2L Standard in one well during one of the sampling events. In the subsequent sampling events the compound was not detected at concentrations above the 2L standard in any of the wells. In results from all the recent sampling events, fluoride was not reported in any well at concentrations that exceed the NC 2L Standard. 2.3.3 Main Plant Groundwater For the evaluation of corrective measure alternatives below, the entire main plant area groundwater has been evaluated collectively. Within the Main Plant, the primary COIs identified by the RFI in soils were addressed in the interim measures work and soil removal activities. No further action is required to address direct contact pathways for soils at the SWMUs and AOCs in the plant area. The RFI identified cyanide, fluoride, arsenic, trichloroethene and trichloromethane (chloroform) as the only COIs in the plant groundwater. Arsenic was detected at an estimated concentration in one well, however arsenic is known to occur naturally in groundwater in Stanly County and other areas within the Carolina Slate Belt. The RFI concluded, and the NCDENR agreed, that because of this fact arsenic was eliminated as a COI from the Site. Phase 3 groundwater sampling results identified available cyanide, fluoride, and trichloroethene at concentrations above the 2L Standard. Trichloromethane was not detected at a concentration above the 2L standard during the Phase 3 investigation in any well sampled.

Financial Statements and Supplementary Data. Report of Independent Registered Public Accounting Firm To the Shareholders and Board of Directors of Alcoa Corporation: In our opinion, the accompanying consolidated balance sheets and the related statements of consolidated operations, consolidated comprehensive (loss) income, changes in consolidated equity, and consolidated cash flows present fairly, in all material respects, the financial position of Alcoa Corporation and its subsidiaries as of December 31, 2016 and 2015, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2016 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation.

Basis of Presentation Alcoa Corporation (or the “Company”) is a vertically integrated aluminum company comprised of bauxite mining, alumina refining, aluminum production (smelting, casting, and rolling), and energy generation. The Company has 43 operating locations in 10 countries around the world, primarily in Australia, Brazil, Canada, Europe, and the United States. References in these Notes to “ParentCo” refer to Alcoa Inc., a Pennsylvania corporation, and its consolidated subsidiaries (through October 31, 2016, at which time was renamed Arconic Inc. (Arconic)). Separation Transaction.On September 28, 2015, ParentCo’s Board of Directors preliminarily approved a plan to separate ParentCo into two standalone, publicly-traded companies (the “Separation Transaction”). One company, later named Alcoa Corporation, was to include the Alumina and Primary Metals segments, which comprised the bauxite mining, alumina refining, aluminum production, and energy operations of ParentCo, as well as the Warrick, Indiana rolling operations and the 25.1% equity interest in the rolling mill at the joint venture in Saudi Arabia, both of which were part of ParentCo’s Global Rolled Products segment. ParentCo, later changed its name to Arconic Inc., was to continue to own the Global Rolled Products (except for the aforementioned rolling operations that were to be included in Alcoa Corporation), Engineered Products and Solutions, and Transportation and Construction Solutions segments. The Separation Transaction was subject to a number of conditions, including, but not limited to: final approval by ParentCo’s Board of Directors (see below); the continuing validity of the private letter ruling from the Internal Revenue Service regarding certain U.S. federal income tax matters relating to the transaction; receipt of an opinion of legal counsel regarding the qualification of the distribution, together with certain related transactions, as a transaction that is generally tax-free for U.S. federal income tax purposes; and the U.S. Securities and Exchange Commission (the “SEC”) declaring effective a Registration Statement on Form 10, as amended, filed with the SEC on October 11, 2016 (effectiveness was declared by the SEC on October 17, 2016). On September 29, 2016, ParentCo’s Board of Directors approved the completion of the Separation Transaction by means of a pro rata distribution by ParentCo of 80.1% of the outstanding common stock of Alcoa Corporation to ParentCo shareholders of record as of the close of business on October 20, 2016 (the “Record Date”). Arconic was to retain the remaining 19.9% of Alcoa Corporation common stock. At the time of the Separation Transaction, ParentCo shareholders were to receive one share of Alcoa Corporation common stock for every three shares of ParentCo common stock held as of the close of business on the Record Date. ParentCo shareholders were to receive cash in lieu of fractional shares. In connection with the Separation Transaction, as of October 31, 2016, Alcoa Corporation entered into certain agreements with Arconic to implement the legal and structural separation between the two companies, govern the relationship between Alcoa Corporation and Arconic after the completion of the Separation Transaction, and allocate between Alcoa Corporation and Arconic various assets, liabilities and obligations, including, among other things, employee benefits, environmental liabilities, intellectual property, and tax-related assets and liabilities. These agreements included a Separation and Distribution Agreement, Tax Matters Agreement, Employee Matters Agreement, Transition Services Agreement, and certain Patent, Know-How, Trade Secret License and Trademark License Agreements. On November 1, 2016 (the “Separation Date”), the Separation Transaction was completed and became effective at 12:01 a.m. Eastern Standard Time. To effect the Separation Transaction, ParentCo undertook a series of transactions to separate the net assets and certain legal entities of ParentCo, resulting in a cash payment of $1,072 to ParentCo by Alcoa Corporation with the net proceeds of a previous debt offering (see Note L). In conjunction with the Separation 102 Transaction, 146,159,428 shares of Alcoa Corporation common stock were distributed to ParentCo shareholders. Additionally, Arconic retained 36,311,767 shares of Alcoa Corporation common stock representing its 19.9% retained interest (on February 14, 2017, Arconic sold 23,353,000 of these shares). “Regular-way” trading of Alcoa Corporation’s common stock began with the opening of the New York Stock Exchange on November 1, 2016 under the ticker symbol “AA.” Alcoa Corporation’s common stock has a par value of $0.01 per share. ParentCo incurred costs to evaluate, plan, and execute the Separation Transaction, and Alcoa Corporation was allocated a pro rata portion of those costs based on segment revenue (see Cost Allocations below). ParentCo recognized $152 from January 2016 through October 2016 and $24 in 2015 for costs related to the Separation Transaction, of which $68 and $12, respectively, was allocated to Alcoa Corporation. The allocated amounts were included in Selling, general administrative, and other expenses on the accompanying Statement of Consolidated Operations. Basis of Presentation.The Consolidated Financial Statements of Alcoa Corporation are prepared in conformity with accounting principles generally accepted in the United States of America (GAAP) and require management to make certain judgments, estimates, and assumptions. These may affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements. They also may affect the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates upon subsequent resolution of identified matters. Principles of Consolidation.The Consolidated Financial Statements of Alcoa Corporation include the accounts of Alcoa Corporation and companies in which Alcoa Corporation has a controlling interest, including those that comprise the Alcoa World Alumina & Chemicals (AWAC) joint venture (see below). Intercompany transactions have been eliminated. The equity method of accounting is used for investments in affiliates and other joint ventures over which Alcoa Corporation has significant influence but does not have effective control. Investments in affiliates in which Alcoa Corporation cannot exercise significant influence are accounted for on the cost method. AWAC is an unincorporated global joint venture between Alcoa Corporation and Alumina Limited of Australia (Alumina Limited) and consists of a number of affiliated operating entities, which own, or have an interest in, or operate the bauxite mines and alumina refineries within Alcoa Corporation’s Bauxite and Alumina segments (except for the Poços de Caldas mine and refinery and a portion of the São Luís refinery, all in Brazil) and the Portland smelter in Australia. Alcoa Corporation owns 60% and Alumina Limited owns 40% of these individual entities, which are consolidated by the Company for financial reporting purposes and include Alcoa of Australia Limited (AofA), Alcoa World Alumina LLC (AWA), and Alcoa World Alumina Brasil Ltda. (AWAB). Alumina Limited’s interest in the equity of such entities is reflected as Noncontrolling interest on the accompanying Consolidated Balance Sheet. In 2016, 2015, and 2014, AWAC received $48, $2, and $43, respectively, in contributions from Alumina Limited. Management evaluates whether an Alcoa Corporation entity or interest is a variable interest entity and whether Alcoa Corporation is the primary beneficiary. Consolidation is required if both of these criteria are met. Alcoa Corporation does not have any variable interest entities requiring consolidation. Prior to the Separation Date, Alcoa Corporation did not operate as a separate, standalone entity. Alcoa Corporation’s operations were included in ParentCo’s financial results. Accordingly, for all periods prior to the Separation Date, the accompanying Consolidated Financial Statements were prepared from ParentCo’s historical accounting records and were presented on a standalone basis as if Alcoa Corporation’s operations had been conducted independently from ParentCo. Such Consolidated Financial Statements include the historical operations that were considered to comprise Alcoa Corporation’s businesses, as well as certain assets and liabilities that were historically held at ParentCo’s corporate level but were specifically identifiable or otherwise attributable to Alcoa Corporation. ParentCo’s net investment in these operations is reflected as Parent Company net investment in the accompanying Consolidated Balance Sheet. All significant transactions and accounts within Alcoa Corporation have been eliminated. All significant intercompany transactions between ParentCo and Alcoa Corporation were included within Parent Company net investment in the accompanying Consolidated Financial Statements. 103 Cost Allocations.The description and information on cost allocations is applicable for all periods included in the Consolidated Financial Statements prior to the Separation Date. The Consolidated Financial Statements of Alcoa Corporation include general corporate expenses of ParentCo that were not historically charged to Alcoa Corporation for certain support functions that were provided on a centralized basis, such as expenses related to finance, audit, legal, information technology, human resources, communications, compliance, facilities, employee benefits and compensation, and research and development activities. These general corporate expenses were included in the accompanying Statement of Consolidated Operations within Cost of goods sold, Selling, general administrative and other expenses, and Research and development expenses. These expenses were allocated to Alcoa Corporation on the basis of direct usage when identifiable, with the remainder allocated based on Alcoa Corporation’s segment revenue as a percentage of ParentCo’s total segment revenue for both Alcoa Corporation and Arconic. All external debt not directly attributable to Alcoa Corporation was excluded from the accompanying Consolidated Balance Sheet of Alcoa Corporation. Financing costs related to these debt obligations were allocated to Alcoa Corporation based on the ratio of capital invested in Alcoa Corporation to the total capital invested by ParentCo in both Alcoa Corporation and Arconic, and were included in the accompanying Statement of Consolidated Operations within Interest expense. The following table reflects the allocations described above: 2016 2015 2014 Cost of goods sold(1)$40 $93 $76 Selling, general administrative, and other expenses(2)150 146 158 Research and development expenses 2 17 21 Provision for depreciation, depletion, and amortization 18 22 37 Restructuring and other charges(3)13223 Interest expense 198 245 278 Other (income) expenses, net $ (7) $ 12 $ 5 (1)Allocation principally relates to expenses for ParentCo’s retained pension and other postretirement benefits associated with closed and sold operations. (2)Allocation includes costs incurred by ParentCo associated with the Separation Transaction (see Separation Transaction above). (3)Allocation primarily relates to layoff programs for ParentCo corporate employees. Management believes the assumptions regarding the allocation of ParentCo’s general corporate expenses and financing costs were reasonable. Nevertheless, the Consolidated Financial Statements of Alcoa Corporation may not include all of the actual expenses that would have been incurred and may not reflect Alcoa Corporation’s consolidated results of operations, financial position, and cash flows had it been a standalone company during the periods prior to the Separation Date. Actual costs that would have been incurred if Alcoa Corporation had been a standalone company would depend on multiple factors, including organizational structure, capital structure, and strategic decisions made in various areas, including information technology and infrastructure. Transactions between Alcoa Corporation and ParentCo, including sales to Arconic, were included as related party transactions in the Consolidated Financial Statements and are considered to be effectively settled for cash at the time the transaction was recorded. The total net effect of the settlement of these transactions is reflected in the accompanying Statement of Consolidated Cash Flows as a financing activity and in the accompanying Consolidated Balance Sheet as Parent Company net investment. Cash Management.The description and information on cash management is applicable for all periods included in the Consolidated Financial Statements prior to the Separation Date. 104 Cash was managed centrally with certain net earnings reinvested locally and working capital requirements met from existing liquid funds. Accordingly, the cash and cash equivalents held by ParentCo at the corporate level were not attributed to Alcoa Corporation for any of the periods prior to the Separation Date. Only cash amounts specifically attributable to Alcoa Corporation were reflected in the accompanying Consolidated Balance Sheet. Transfers of cash, both to and from ParentCo’s centralized cash management system, were reflected as a component of Parent Company net investment in the accompanying Consolidated Balance Sheet and as a financing activity on the accompanying Consolidated Statement of Cash Flows. ParentCo had an arrangement with several financial institutions to sell certain customer receivables without recourse on a revolving basis. The sale of such receivables was completed through the use of a bankruptcy-remote special- purpose entity, which was a consolidated subsidiary of ParentCo. In connection with this arrangement, certain of Alcoa Corporation’s customer receivables were sold on a revolving basis to this bankruptcy-remote subsidiary of ParentCo; these sales were reflected as a component of Parent Company net investment in the accompanying Consolidated Balance Sheet. ParentCo participated in several accounts payable settlement arrangements with certain vendors and third-party intermediaries. These arrangements provided that, at the vendor’s request, the third-party intermediary advance the amount of the scheduled payment to the vendor, less an appropriate discount, before the scheduled payment date and ParentCo made payment to the third-party intermediary on the date stipulated in accordance with the commercial terms negotiated with its vendors. In connection with these arrangements, certain of Alcoa Corporation’s accounts payable were settled, at the vendor’s request, before the scheduled payment date; these settlements were reflected as a component of Parent Company net investment in the accompanying Consolidated Balance Sheet. Related Party Transactions.Alcoa Corporation buys products from and sells products to various related companies, consisting of entities in which Alcoa Corporation retains a 50% or less equity interest, at negotiated prices between the two parties. These transactions were not material to the financial position or results of operations of Alcoa Corporation for all periods presented. Transactions between Alcoa Corporation and Arconic have been presented as related party transactions in the accompanying Consolidated Financial Statements. Sales to Arconic from Alcoa Corporation were $958, $1,078, and $1,783 in 2016, 2015, and 2014, respectively. As of December 31, 2016, outstanding receivables from Arconic were not material to the accompanying Consolidated Balance Sheet. B. Summary of Significant Accounting Policies Cash Equivalents.Cash equivalents are highly liquid investments purchased with an original maturity of three months or less. Inventory Valuation.Inventories are carried at the lower of cost or market, with cost for a substantial portion of U.S. and Canadian inventories determined under the last-in, first-out (LIFO) method. The cost of other inventories is principally determined under the average-cost method. 105 Properties, Plants, and Equipment.Properties, plants, and equipment are recorded at cost. Depreciation is recorded principally on the straight-line method at rates based on the estimated useful lives of the assets. For greenfield assets, which refer to the construction of new assets on undeveloped land, the units of production method is used to record depreciation. These assets require a significant period (generally greater than one-year) to ramp-up to full production capacity. As a result, the units of production method is deemed a more systematic and rational method for recognizing depreciation on these assets. Depreciation is recorded on temporarily idled facilities until such time management approves a permanent closure. The following table details the weighted-average useful lives of structures and machinery and equipment by reporting segment (numbers in years): Segment Structures Machinery and equipment Bauxite 35 17 Alumina 30 27 Aluminum 36 22 Cast Products 33 19 Energy 34 25 Rolled Products 31 22 Gains or losses from the sale of assets are generally recorded in other income or expenses. Repairs and maintenance are charged to expense as incurred. Interest related to the construction of qualifying assets is capitalized as part of the construction costs. Properties, plants, and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets (asset group) may not be recoverable. Recoverability of assets is determined by comparing the estimated undiscounted net cash flows of the operations related to the assets (asset group) to their carrying amount. An impairment loss would be recognized when the carrying amount of the assets (asset group) exceeds the estimated undiscounted net cash flows. The amount of the impairment loss to be recorded is calculated as the excess of the carrying value of the assets (asset group) over their fair value, with fair value determined using the best information available, which generally is a discounted cash flow (DCF) model. The determination of what constitutes an asset group, the associated estimated undiscounted net cash flows, and the estimated useful lives of assets also require significant judgments. Equity Investments.Alcoa Corporation invests in a number of privately-held companies, primarily through joint ventures and consortia, which are accounted for using the equity method. The equity method is applied in situations where Alcoa Corporation has the ability to exercise significant influence, but not control, over the investee. Management reviews equity investments for impairment whenever certain indicators are present suggesting that the carrying value of an investment is not recoverable. This analysis requires a significant amount of judgment from management to identify events or circumstances indicating that an equity investment is impaired. The following items are examples of impairment indicators: significant, sustained declines in an investee’s revenue, earnings, and cash flow trends; adverse market conditions of the investee’s industry or geographic area; the investee’s ability to continue operations measured by several items, including liquidity; and other factors. Once an impairment indicator is identified, management uses considerable judgment to determine if the impairment is other than temporary, in which case the equity investment is written down to its estimated fair value. An impairment that is other than temporary could significantly and adversely impact reported results of operations. Deferred Mining Costs.Alcoa Corporation recognizes deferred mining costs during the development stage of a mine life cycle. Such costs include the construction of access and haul roads, detailed drilling and geological analysis to further define the grade and quality of the known bauxite, and overburden removal costs. These costs relate to sections of the related mines where Alcoa Corporation is either currently extracting bauxite or is preparing for production in the near term. These sections are outlined and planned incrementally and generally are mined over periods ranging from one to five years, depending on mine specifics. The amount of geological drilling and testing necessary to determine the economic viability of the bauxite deposit being mined is such that the reserves are considered to be proven, and the 106 mining costs are amortized based on this level of reserves. Deferred mining costs are included in Other noncurrent assets on the accompanying Consolidated Balance Sheet. Goodwill and Other Intangible Assets.Goodwill is not amortized; instead, it is reviewed for impairment annually (in the fourth quarter) or more frequently if indicators of impairment exist or if a decision is made to sell or exit a business. A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include deterioration in general economic conditions, negative developments in equity and credit markets, adverse changes in the markets in which an entity operates, increases in input costs that have a negative effect on earnings and cash flows, or a trend of negative or declining cash flows over multiple periods, among others. The fair value that could be realized in an actual transaction may differ from that used to evaluate the impairment of goodwill. Goodwill is allocated among and evaluated for impairment at the reporting unit level, which is defined as an operating segment or one level below an operating segment. Alcoa Corporation has six reporting units as follows: Bauxite, Alumina, Aluminum, Cast Products, Energy, and Rolled Products. Of these six reporting units, only Bauxite and Alumina contain goodwill. As of December 31, 2016, the carrying value of the goodwill for Bauxite and Alumina was $52 and $103, respectively. These amounts include an allocation of goodwill held at the corporate level (see Note K). In reviewing goodwill for impairment, an entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (greater than 50%) that the estimated fair value of a reporting unit is less than its carrying amount. If an entity elects to perform a qualitative assessment and determines that an impairment is more likely than not, the entity is then required to perform the existing two-step quantitative impairment test (described below), otherwise no further analysis is required. An entity also may elect not to perform the qualitative assessment and, instead, proceed directly to the two-step quantitative impairment test. The ultimate outcome of the goodwill impairment review for a reporting unit should be the same whether an entity chooses to perform the qualitative assessment or proceeds directly to the two-step quantitative impairment test. Alcoa Corporation’s policy for its annual review of goodwill is to perform the qualitative assessment for all reporting units not subjected directly to the two-step quantitative impairment test. Generally, management will proceed directly to the two-step quantitative impairment test for each of its two reporting units that contain goodwill at least once during every three-year period, as part of its annual review of goodwill. Under the qualitative assessment, various events and circumstances (or factors) that would affect the estimated fair value of a reporting unit are identified (similar to impairment indicators above). These factors are then classified by the type of impact they would have on the estimated fair value using positive, neutral, and adverse categories based on current business conditions. Additionally, an assessment of the level of impact that a particular factor would have on the estimated fair value is determined using high, medium, and low weighting. Furthermore, management considers the results of the most recent two-step quantitative impairment test completed for a reporting unit and compares the weighted average cost of capital (WACC) between the current and prior years for each reporting unit. During the 2016 annual review of goodwill, management performed the qualitative assessment for the Bauxite reporting unit. Management concluded it was not more likely than not that the estimated fair value of this reporting unit was less than its carrying value. As such, no further analysis was required. Under the two-step quantitative impairment test, the evaluation of impairment involves comparing the current fair value of each reporting unit to its carrying value, including goodwill. Alcoa Corporation uses a DCF model to estimate the current fair value of its reporting units when testing for impairment, as management believes forecasted cash flows are the best indicator of such fair value. A number of significant assumptions and estimates are involved in the application of the DCF model to forecast operating cash flows, including markets and market share, sales volumes and prices, production costs, tax rates, capital spending, discount rate, and working capital changes. Certain of these assumptions can vary significantly among the reporting units. Cash flow forecasts are generally based on approved business unit operating plans for the early years and historical relationships in later years. The betas used in calculating the individual reporting units’ WACC rate are estimated for each business with the assistance of valuation experts. 107 In the event the estimated fair value of a reporting unit per the DCF model is less than the carrying value, additional analysis would be required. The additional analysis would compare the carrying amount of the reporting unit’s goodwill with the implied fair value of that goodwill, which may involve the use of valuation experts. The implied fair value of goodwill is the excess of the fair value of the reporting unit over the fair value amounts assigned to all of the assets and liabilities of that unit as if the reporting unit was acquired in a business combination and the fair value of the reporting unit represented the purchase price. If the carrying value of goodwill exceeds its implied fair value, an impairment loss equal to such excess would be recognized. During the 2016 annual review of goodwill, management proceeded directly to the two-step quantitative impairment test for the Alumina reporting unit. The estimated fair value of this reporting unit was substantially in excess of its carrying value, resulting in no impairment. Goodwill impairment tests in all prior years presented indicated that goodwill was not impaired for any of Alcoa Corporation’s reporting units, and there were no triggering events since that time that necessitated an impairment test. Intangible assets with finite useful lives are amortized generally on a straight-line basis over the periods benefited. The following table details the weighted-average useful lives of software and other intangible assets by reporting segment (numbers in years): Segment Software Other intangible assets Bauxite 8 10 Alumina 7 19 Aluminum 6 38 Cast Products 3 — Energy 437 Rolled Products 6 20 Asset Retirement Obligations.Alcoa Corporation recognizes asset retirement obligations (AROs) related to legal obligations associated with the normal operation of bauxite mines, alumina refineries, and aluminum smelters. These AROs consist primarily of costs associated with mine reclamation, closure of bauxite residue areas, spent pot lining disposal, and landfill closure. Alcoa Corporation also recognizes AROs for any significant lease restoration obligation, if required by a lease agreement, and for the disposal of regulated waste materials related to the demolition of certain power facilities. The fair values of these AROs are recorded on a discounted basis, at the time the obligation is incurred, and accreted over time for the change in present value. Additionally, Alcoa Corporation capitalizes asset retirement costs by increasing the carrying amount of the related long-lived assets and depreciating these assets over their remaining useful life. Certain conditional asset retirement obligations (CAROs) related to alumina refineries, aluminum smelters, rolling mills, and energy generation facilities have not been recorded in the Consolidated Financial Statements due to uncertainties surrounding the ultimate settlement date. A CARO is a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement are conditional on a future event that may or may not be within Alcoa Corporation’s control. Such uncertainties exist as a result of the perpetual nature of the structures, maintenance and upgrade programs, and other factors. At the date a reasonable estimate of the ultimate settlement date can be made (e.g., planned demolition), Alcoa Corporation would record an ARO for the removal, treatment, transportation, storage, and/or disposal of various regulated assets and hazardous materials such as asbestos, underground and aboveground storage tanks, polychlorinated biphenyls (PCBs), various process residuals, solid wastes, electronic equipment waste, and various other materials. Such amounts may be material to the Consolidated Financial Statements in the period in which they are recorded. Environmental Matters.Expenditures for current operations are expensed or capitalized, as appropriate. Expenditures relating to existing conditions caused by past operations, which will not contribute to future revenues, are expensed. Liabilities are recorded when remediation costs are probable and can be reasonably estimated. The liability may include costs such as site investigations, consultant fees, feasibility studies, outside contractors, and monitoring 108 expenses. Estimates are generally not discounted or reduced by potential claims for recovery. Claims for recovery are recognized as agreements are reached with third parties. The estimates also include costs related to other potentially responsible parties to the extent that Alcoa Corporation has reason to believe such parties will not fully pay their proportionate share. The liability is continuously reviewed and adjusted to reflect current remediation progress, prospective estimates of required activity, and other factors that may be relevant, including changes in technology or regulations. Litigation Matters.For asserted claims and assessments, liabilities are recorded when an unfavorable outcome of a matter is deemed to be probable and the loss is reasonably estimable. Management determines the likelihood of an unfavorable outcome based on many factors such as, among others, the nature of the matter, available defenses and case strategy, progress of the matter, views and opinions of legal counsel and other advisors, applicability and success of appeals processes, and the outcome of similar historical matters. Once an unfavorable outcome is deemed probable, management weighs the probability of estimated losses, and the most reasonable loss estimate is recorded. If an unfavorable outcome of a matter is deemed to be reasonably possible, then the matter is disclosed and no liability is recorded. With respect to unasserted claims or assessments, management must first determine that the probability that an assertion will be made is likely, then, a determination as to the likelihood of an unfavorable outcome and the ability to reasonably estimate the potential loss is made. Legal matters are reviewed on a continuous basis to determine if there has been a change in management’s judgment regarding the likelihood of an unfavorable outcome or the estimate of a potential loss. Revenue Recognition.Alcoa Corporation recognizes revenue when title, ownership, and risk of loss pass to the customer, all of which occurs upon shipment or delivery of the product and is based on the applicable shipping terms. The shipping terms vary across all businesses and depend on the product, the country of origin, and the type of transportation (truck, train, or vessel). Alcoa Corporation periodically enters into long-term supply contracts with alumina and aluminum customers and receives advance payments for product to be delivered in future periods. These advance payments are recorded as deferred revenue, and revenue is recognized as shipments are made and title, ownership, and risk of loss pass to the customer during the term of the contracts. Deferred revenue is included in Other current liabilities and Other noncurrent liabilities and deferred credits on the accompanying Consolidated Balance Sheet. Stock-Based Compensation.For all periods prior to the Separation Date (see Note A), employees attributable to Alcoa Corporation operations participated in ParentCo’s stock-based compensation plans. The compensation expense recorded by Alcoa Corporation included the expense associated with these employees, as well as the expense associated with the allocation of stock-based compensation expense for ParentCo’s corporate employees. From the Separation Date through December 31, 2016, Alcoa Corporation recorded stock-based compensation expense for all of the Company’s employees. The following accounting policy describes how stock-based compensation expense is initially determined for both Alcoa Corporation and ParentCo. Compensation expense for employee equity grants is recognized using the non-substantive vesting period approach, in which the expense (net of estimated forfeitures) is recognized ratably over the requisite service period based on the grant date fair value. The fair value of new stock options is estimated on the date of grant using a lattice-pricing model. Determining the fair value of stock options at the grant date requires judgment, including estimates for the average risk-free interest rate, dividend yield, volatility, annual forfeiture rate, and exercise behavior. These assumptions may differ significantly between grant dates because of changes in the actual results of these inputs that occur over time. Most plan participants can choose whether to receive their award in the form of stock options, stock awards, or a combination of both. This choice is made before the grant is issued and is irrevocable. Pension and Other Postretirement Benefit Plans.For all periods prior to August 1, 2016 (see below), certain employees attributable to Alcoa Corporation operations participated in defined benefit pension and other postretirement benefit plans (the “Shared Plans”) sponsored by ParentCo, which also included participants attributable to non-Alcoa Corporation operations. Alcoa Corporation accounted for these Shared Plans as multiemployer benefit 109 plans. Accordingly, Alcoa Corporation did not record an asset or liability to recognize the funded status of the Shared Plans. However, the related expense recorded by Alcoa Corporation was based primarily on pensionable compensation and estimated interest costs related to employees attributable to Alcoa Corporation operations. Prior to the Separation Date (see Note A), certain other plans that were entirely attributable to employees of Alcoa Corporation-related operations (the “Direct Plans”) were accounted for as defined benefit pension and other postretirement benefit plans. Accordingly, the funded and unfunded position of each Direct Plan was recorded in the Consolidated Balance Sheet. Actuarial gains and losses that had not yet been recognized through earnings were recorded in accumulated other comprehensive income, net of taxes, until they were amortized as a component of net periodic benefit cost. The determination of benefit obligations and recognition of expenses related to Direct Plans is dependent on various assumptions. The major assumptions primarily relate to discount rates, long-term expected rates of return on plan assets, and future compensation increases. ParentCo’s management developed each assumption using relevant company experience in conjunction with market-related data for each individual location in which such plans exist. In preparation for the Separation Transaction (see Note A), effective August 1, 2016, certain of the Shared Plans were separated into standalone plans for both Alcoa Corporation and ParentCo (see Note N). Additionally, certain of the other remaining Shared Plans were assumed by Alcoa Corporation (See Note N). Accordingly, from August 1, 2016 through December 31, 2016, the standalone plans and assumed plans were accounted for as defined benefit pension and other postretirement plans. Additionally, the Direct Plans continued to be accounted for as defined benefit pension and other postretirement plans through December 31, 2016. Derivatives and Hedging.Derivatives are held for purposes other than trading and are part of a formally documented risk management program. For derivatives designated as fair value hedges, Alcoa Corporation measures hedge effectiveness by formally assessing, at inception and at least quarterly, the historical high correlation of changes in the fair value of the hedged item and the derivative hedging instrument. For derivatives designated as cash flow hedges, Alcoa Corporation measures hedge effectiveness by formally assessing, at inception and at least quarterly, the probable high correlation of the expected future cash flows of the hedged item and the derivative hedging instrument. The ineffective portions of both types of hedges are recorded in sales or other income or expense in the current period. If the hedging relationship ceases to be highly effective or it becomes probable that an expected transaction will no longer occur, future gains or losses on the derivative instrument are recorded in other income or expense. Alcoa Corporation accounts for hedges of firm customer commitments for aluminum as fair value hedges. As a result, the fair values of the derivatives and changes in the fair values of the underlying hedged items are reported in other current and noncurrent assets and liabilities in the Consolidated Balance Sheet. Changes in the fair values of these derivatives and underlying hedged items generally offset and are recorded each period in sales, consistent with the underlying hedged item. Alcoa Corporation accounts for hedges of foreign currency exposures and certain forecasted transactions as cash flow hedges. The fair values of the derivatives are recorded in other current and noncurrent assets and liabilities in the Consolidated Balance Sheet. The effective portions of the changes in the fair values of these derivatives are recorded in other comprehensive income and are reclassified to sales, cost of goods sold, or other income or expense in the period in which earnings are impacted by the hedged items or in the period that the transaction no longer qualifies as a cash flow hedge. These contracts cover the same periods as known or expected exposures, generally not exceeding five years. If no hedging relationship is designated, the derivative is marked to market through earnings. Cash flows from derivatives are recognized in the Statement of Consolidated Cash Flows in a manner consistent with the underlying transactions. Income Taxes.From the Separation Date (see Note A) through December 31, 2016, the provision for income taxes was determined using the asset and liability approach of accounting for income taxes. Under this approach, the 110 provision for income taxes represents income taxes paid or payable (or received or receivable) for the current year plus the change in deferred taxes during the year. Deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid, and result from differences between the financial and tax bases of Alcoa Corporation’s assets and liabilities and are adjusted for changes in tax rates and tax laws when enacted. In all periods prior to the Separation Date, Alcoa Corporation’s operations were included in the income tax filings of ParentCo. The provision for income taxes in Alcoa Corporation’s Statement of Consolidated Operations was determined in the same manner described above, but on a separate return methodology as if the Company was a standalone taxpayer filing hypothetical income tax returns where applicable. Any additional accrued tax liability or refund arising as a result of this approach was assumed to be immediately settled with ParentCo as a component of Parent Company net investment. Deferred tax assets were also determined in the same manner described above and were reflected in the Consolidated Balance Sheet for net operating losses, credits or other attributes to the extent that such attributes were expected to transfer to Alcoa Corporation upon the Separation Transaction (see Note A). Any difference from attributes generated in a hypothetical return on a separate return basis was adjusted as a component of Parent Company net investment. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not (greater than 50%) that a tax benefit will not be realized. In evaluating the need for a valuation allowance, management considers all potential sources of taxable income, including income available in carryback periods, future reversals of taxable temporary differences, projections of taxable income, and income from tax planning strategies, as well as all available positive and negative evidence. Positive evidence includes factors such as a history of profitable operations, projections of future profitability within the carryforward period, including from tax planning strategies, and Alcoa Corporation’s experience with similar operations. Existing favorable contracts and the ability to sell products into established markets are additional positive evidence. Negative evidence includes items such as cumulative losses, projections of future losses, or carryforward periods that are not long enough to allow for the utilization of a deferred tax asset based on existing projections of income. Deferred tax assets for which no valuation allowance is recorded may not be realized upon changes in facts and circumstances, resulting in a future charge to establish a valuation allowance. Existing valuation allowances are re-examined under the same standards of positive and negative evidence. If it is determined that it is more likely than not that a deferred tax asset will be realized, the appropriate amount of the valuation allowance, if any, is released. Deferred tax assets and liabilities are also re-measured to reflect changes in underlying tax rates due to law changes and the granting and lapse of tax holidays. Tax benefits related to uncertain tax positions taken or expected to be taken on a tax return are recorded when such benefits meet a more likely than not threshold. Otherwise, these tax benefits are recorded when a tax position has been effectively settled, which means that the statute of limitation has expired or the appropriate taxing authority has completed their examination even though the statute of limitations remains open. Interest and penalties related to uncertain tax positions are recognized as part of the provision for income taxes and are accrued beginning in the period that such interest and penalties would be applicable under relevant tax law until such time that the related tax benefits are recognized. Foreign Currency.The local currency is the functional currency for Alcoa Corporation’s significant operations outside the United States, except for certain operations in Canada and Iceland, where the U.S. dollar is used as the functional currency. The determination of the functional currency for Alcoa Corporation’s operations is made based on the appropriate economic and management indicators. Recently Adopted Accounting Guidance.On January 1, 2016, Alcoa Corporation adopted changes issued by the Financial Accounting Standards Board (FASB) to the presentation of extraordinary items. Such items are defined as transactions or events that are both unusual in nature and infrequent in occurrence, and, previously, were required to be presented separately in an entity’s income statement, net of income tax, after income from continuing operations. The changes eliminate the concept of an extraordinary item and, therefore, the presentation of such items is no longer required. Notwithstanding this change, an entity is still required to present and disclose a transaction or event that is 111 both unusual in nature and infrequent in occurrence in the notes to the financial statements. The adoption of these changes had no impact on the Consolidated Financial Statements. On January 1, 2016, Alcoa Corporation adopted changes issued by the FASB to the analysis an entity must perform to determine whether it should consolidate certain types of legal entities. These changes (i) modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities or voting interest entities, (ii) eliminate the presumption that a general partner should consolidate a limited partnership, (iii) affect the consolidation analysis of reporting entities that are involved with variable interest entities, particularly those that have fee arrangements and related party relationships, and (iv) provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. The adoption of these changes had no impact on the Consolidated Financial Statements. On January 1, 2016, Alcoa Corporation adopted changes issued by the FASB to the presentation of debt issuance costs. Previously, such costs were required to be presented as a noncurrent asset in an entity’s balance sheet and amortized into interest expense over the term of the related debt instrument. The changes require that debt issuance costs be presented in an entity’s balance sheet as a direct deduction from the carrying value of the related debt liability. The amortization of debt issuance costs remains unchanged. The FASB issued an update to these changes based on an announcement of the staff of the SEC. This update provides an exception to the FASB changes allowing, but not requiring, debt issuance costs related to line-of-credit arrangements to continue to be presented as an asset regardless of whether there are any outstanding borrowings under such arrangement. This additional change also was adopted by Alcoa Corporation on January 1, 2016. The adoption of these changes had an immaterial impact on the Consolidated Financial Statements. On January 1, 2016, Alcoa Corporation adopted changes issued by the FASB to the presentation in the fair value hierarchy of the fair value of certain investments. An entity is permitted to measure the fair value of certain investments using the net asset value per share as a practical expedient. Previously, such investments were categorized in the fair value hierarchy on the basis of whether the investment was redeemable with the investee at net asset value on the measurement date, never redeemable with the investee at net asset value, or redeemable with the investee at net asset value at a future date. However, the application of this criteria to determine the proper category in which these investments should be included in the fair value hierarchy differed from the criteria used to categorize other fair value measurements within the hierarchy. As a result, to remove this inconsistency, these changes eliminate the requirement to categorize such investments in the fair value hierarchy. Instead, an entity is required to present such investments outside the fair value hierarchy as a separate category of investments. In accordance with these changes, Alcoa Corporation removed a significant amount of investments related to its pension plans from the fair value hierarchy and presented them as a separate category (see Note N). Other than a change in the disclosure of such investments, the adoption of these changes had no impact on the Consolidated Financial Statements. In 2016, Alcoa Corporation adopted changes issued by the FASB to the disclosure of uncertainties about an entity’s ability to continue as a going concern. Under GAAP, continuation of a reporting entity as a going concern is presumed as the basis for preparing financial statements unless and until the entity’s liquidation becomes imminent. Even if an entity’s liquidation is not imminent, there may be conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern. Because there is no guidance in GAAP about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern or to provide related note disclosures, there is diversity in practice whether, when, and how an entity discloses the relevant conditions and events in its financial statements. As a result, these changes require an entity’s management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that financial statements are issued. Substantial doubt is defined as an indication that it is probable that an entity will be unable to meet its obligations as they become due within one year after the date that financial statements are issued. If management has concluded that substantial doubt exists, then the following disclosures should be made in the financial statements: (i) principal conditions or events that raised the substantial doubt, (ii) management’s evaluation of the significance of those conditions or events in relation to the 112 entity’s ability to meet its obligations, (iii) management’s plans that alleviated the initial substantial doubt or, if substantial doubt was not alleviated, management’s plans that are intended to at least mitigate the conditions or events that raise substantial doubt, and (iv) if the latter in (iii) is disclosed, an explicit statement that there is substantial doubt about the entity’s ability to continue as a going concern. The adoption of these changes had no impact on the Consolidated Financial Statements. Going forward, this guidance will need to continue to be applied by management at the end of each annual period and interim period therein to determine what, if any, impact there may be on the Consolidated Financial Statements in a given reporting period. Recently Issued Accounting Guidance.In January 2016, the FASB issued changes to the accounting and reporting of certain equity investments. These changes require equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer. Additionally, the impairment assessment of equity investments without readily determinable fair values has been simplified by requiring a qualitative assessment to identify impairment. These changes become effective for Alcoa Corporation on January 1, 2018. Management has determined that the adoption of these changes will not have an impact on the Consolidated Financial Statements, as all of Alcoa Corporation’s equity investments are accounted for under the equity method of accounting. In February 2016, the FASB issued changes to the accounting and presentation of leases. These changes require lessees to recognize a right of use asset and lease liability on the balance sheet for all leases with terms longer than 12 months. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize a right of use asset and lease liability. Additionally, when measuring assets and liabilities arising from a lease, optional payments should be included only if the lessee is reasonably certain to exercise an option to extend the lease, exercise a purchase option, or not exercise an option to terminate the lease. These changes become effective for Alcoa Corporation on January 1, 2019. Upon adoption of these changes, management does expect to record a right of use asset and lease liability on Alcoa Corporation’s Consolidated Balance Sheet. While the precise amount of this asset and liability will not be known until closer to the adoption date, based on Alcoa Corporation’s Consolidated Balance Sheet and lease portfolio as of December 31, 2016, the amount is expected to be less than 5% of both total assets and total liabilities. In March 2016, the FASB issued changes to derivative instruments designated as hedging instruments. These changes clarify that a change in the counterparty to a derivative instrument that has been designated as a hedging instrument does not, in and of itself, require de-designation of that hedging relationship provided that all other hedge accounting criteria continue to be met. These changes become effective for Alcoa Corporation on January 1, 2017. Management has determined that the adoption of these changes will not have an immediate impact on the Consolidated Financial Statements. This guidance will need to be considered in the event the existing counterparty to any of Alcoa Corporation’s derivative instruments changes to a new counterparty. In March 2016, the FASB issued changes eliminating the requirement for an investor to adjust an equity method investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held as a result of an increase in the level of ownership interest or degree of influence. Additionally, an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting must recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. These changes become effective for Alcoa Corporation on January 1, 2017. Management has determined that the adoption of these changes will not have an immediate impact on the Consolidated Financial Statements. This guidance will need to be considered in the event any of Alcoa Corporation’s investments undergo a change as previously described. 113 In March 2016, the FASB issued changes to employee share-based payment accounting. Currently, an entity must determine for each share-based payment award whether the difference between the deduction for tax purposes and the compensation cost recognized for financial reporting purposes results in either an excess tax benefit or a tax deficiency. Excess tax benefits are recognized in additional paid-in capital; tax deficiencies are recognized either as an offset to accumulated excess tax benefits, if any, or in the income statement. Excess tax benefits are not recognized until the deduction reduces taxes payable. The changes require all excess tax benefits and tax deficiencies related to share-based payment awards to be recognized as income tax expense or benefit in the income statement. The tax effects of exercised or vested awards should be treated as discrete items in the reporting period in which they occur. An entity also should recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period. Additionally, the presentation of excess tax benefits related to share-based payment awards in the statement of cash flows is changed. Currently, excess tax benefits must be separated from other income tax cash flows and classified as a financing activity. The changes require excess tax benefits to be classified along with other income tax cash flows as an operating activity. Also, the changes require cash paid by an employer when directly withholding shares for tax- withholding purposes to be classified as a financing activity. Currently, there is no specific guidance on the classification in the statement of cash flows of cash paid by an employer to the tax authorities when directly withholding shares for tax-withholding purposes. Additionally, for a share-based award to qualify for equity classification it cannot partially settle in cash in excess of the employer’s minimum statutory withholding requirements. The changes permit equity classification of share-based awards for withholdings up to the maximum statutory tax rates in applicable jurisdictions. These changes become effective for Alcoa Corporation on January 1, 2017. Management has determined that the adoption of these changes will not have a material impact on the Consolidated Financial Statements. In June 2016, the FASB added a new impairment model (known as the current expected credit loss (CECL) model) that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses. The CECL model applies to most debt instruments, trade receivables, lease receivables, financial guarantee contracts, and other loan commitments. The CECL model does not have a minimum threshold for recognition of impairment losses and entities will need to measure expected credit losses on assets that have a low risk of loss. These changes become effective for Alcoa Corporation on January 1, 2020. Management is currently evaluating the potential impact of these changes on the Consolidated Financial Statements. In both August and October 2016, the FASB issued changes to the presentation of a number of items in the statement of cash flows. Specifically, the changes identify nine specific cash flow items and the sections where they must be presented within the statement of cash flows, including distributions received from equity method investees, proceeds from the settlement of insurance claims, and restricted cash. These changes become effective for Alcoa Corporation on January 1, 2018. Management has determined that the adoption of these changes will not have a material impact on the Consolidated Financial Statements. In October 2016, the FASB issued changes to the accounting for intra-entity transactions, other than inventory. Currently, no immediate tax impact is recognized in an entity’s financial statements as a result of intra-entity transfers of assets. An entity is precluded from reflecting a tax benefit or expense from an intra-entity asset transfer between entities that file separate tax returns, whether or not such entities are in different tax jurisdictions, until the asset has been sold to a third party or otherwise recovered. The buyer of such asset is prohibited from recognizing a deferred tax asset for the temporary difference arising from the excess of the buyer’s tax basis over the cost to the seller. The changes require the current and deferred income tax consequences of the intra-entity transfer to be recorded when the transaction occurs. The exception to defer the tax consequences of inventory transactions is maintained. These changes became effective for Alcoa Corporation on January 1, 2017. Management has determined that the adoption of these changes will not have a material impact on the Consolidated Financial Statements. In October 2016, the FASB issued changes to consolidation accounting. Prior to these changes, an entity is required to consider indirect economic interests in a variable interest entity held through related parties under common control as direct interests in their entirety in the entity’s assessment of whether it is the primary beneficiary of the variable interest entity. The changes result in an entity considering such indirect economic interests only on a proportionate basis as 114 indirect interests instead of as direct interests in their entirety. These changes became effective for Alcoa Corporation on January 1, 2017. Management has determined that the adoption of these changes will not have an impact on the Consolidated Financial Statements. This guidance will need to be considered in future assessments of whether Alcoa Corporation is the primary beneficiary of a variable interest entity. In July 2015, the FASB issued changes to the subsequent measurement of inventory. Currently, an entity is required to measure its inventory at the lower of cost or market, whereby market can be replacement cost, net realizable value, or net realizable value less an approximately normal profit margin. The changes require that inventory be measured at the lower of cost and net realizable value, thereby eliminating the use of the other two market methodologies. Net realizable value is defined as the estimated selling prices in the ordinary course of business less reasonably predictable costs of completion, disposal, and transportation. These changes do not apply to inventories measured using LIFO (last-in, first-out) or the retail inventory method. Currently, Alcoa Corporation applies the net realizable value market option to measure non-LIFO inventories at the lower of cost or market. These changes became effective for Alcoa Corporation on January 1, 2017. Management has determined that the adoption of these changes will not have an impact on the Consolidated Financial Statements. In May 2014, the FASB issued changes to the recognition of revenue from contracts with customers. These changes created a comprehensive framework for all entities in all industries to apply in the determination of when to recognize revenue, and, therefore, supersede virtually all existing revenue recognition requirements and guidance. This framework is expected to result in less complex guidance in application while providing a consistent and comparable methodology for revenue recognition. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this principle, an entity should apply the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract(s), (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract(s), and (v) recognize revenue when, or as, the entity satisfies a performance obligation. In August 2015, the FASB deferred the effective date by one year, making these changes effective for Alcoa Corporation on January 1, 2018. Management has not yet finalized its assessment of the potential impact of these changes on the Consolidated Financial Statements, but does not currently expect the adoption of these changes to have a material impact on the Consolidated Financial Statements. C. Acquisitions and Divestitures 2016 Divestitures.In July 2016, Alcoa Corporation’s wholly-owned subsidiary, Alcoa Power Generating Inc., reached an agreement to sell its 215-megawatt Yadkin Hydroelectric Project (Yadkin) to Cube Hydro Carolinas, LLC. Yadkin encompasses four hydroelectric power developments (reservoirs, dams and powerhouses), known as High Rock, Tuckertown, Narrows and Falls, situated along a 38-mile stretch of the Yadkin River through the central part of North Carolina. This transaction is expected to close in the first half of 2017, subject to customary federal and state regulatory approvals (see Note T). Upon completion of this transaction, Alcoa Corporation will pay to Arconic the after-tax proceeds it receives in accordance with the Separation and Distribution Agreement entered into by both companies in conjunction with the Separation Transaction (see Note A). As a result, Alcoa Corporation recorded a liability of $243, which is reflected in Other current liabilities on the accompanying Consolidated Balance Sheet as of December 31, 2016, representing the estimated future payment to Arconic. The power generated by Yadkin is primarily sold into the open market. Yadkin generated sales of $29 in 2016 and had approximately 30 employees as of December 31, 2016. The carrying value of the net assets to be sold was $125 and $127 as of December 31, 2016 and 2015, respectively, which consists mostly of properties, plants, and equipment. 2015 Divestitures.In 2015, Alcoa Corporation had post-closing adjustments, as provided for in the respective purchase agreements, related to two divestitures completed in December 2014 (see 2014 Divestitures below). The combined post-closing adjustments resulted in net cash received of $41 and a net loss of $24, which was recorded in Restructuring and other charges (see Note D) on the accompanying Statement of Consolidated Operations. These two divestitures are no longer subject to post-closing adjustments. 115 2014 Divestitures.In 2014, Alcoa Corporation completed the divestiture of three operations as described below. Combined, these transactions yielded net cash proceeds of $223 and resulted in a net loss of $216, which was recorded in Restructuring and other charges (see Note D) on the accompanying Statement of Consolidated Operations. Two of the three transactions were subject to certain post-closing adjustments as defined in the respective purchase agreements as of December 31, 2014 (see 2015 Divestitures above). In November 2014, Alcoa Corporation completed the sale of an aluminum rod plant located in Bécancour, Québec, Canada to Sural Laminated Products. This facility takes molten aluminum and shapes it into the form of a rod, which is used by customers primarily for the transportation of electricity. While owned by Alcoa Corporation, the operating results and assets and liabilities of this plant were included in the former Primary Metals segment (see Note E). In conjunction with this transaction, Alcoa Corporation entered into a multi-year agreement with Sural Laminated Products to supply molten aluminum for the rod plant. The aluminum rod plant generated sales of approximately $200 in 2013 and, at the time of divestiture, had approximately 60 employees. In December 2014, Alcoa Corporation’s majority-owned subsidiary (60%), Alcoa Minerals of Jamaica, LLC (AMJ, part of AWAC), completed the sale of its 55% ownership stake in a bauxite mine and alumina refinery joint venture in Jamaica to Noble Group Ltd. While owned by AMJ, 55% of both the operating results and assets and liabilities of this joint venture were included in the former Alumina segment (see Note E). As it relates to AMJ’s previous 55% ownership stake, the refinery (AMJ’s share of the capacity was 779 kmt-per-year) generated sales (third-party and intersegment) of approximately $200 in 2013, and the refinery and mine combined, at the time of divestiture, had approximately 500 employees. Also in December 2014, Alcoa Corporation completed the sale of its 50.33% ownership stake in the Mt. Holly smelter located in Goose Creek, South Carolina to Century Aluminum Company. While owned by Alcoa Corporation, 50.33% of both the operating results and assets and liabilities related to the smelter were included in the former Primary Metals segment (see Note E). As it relates to Alcoa Corporation’s previous 50.33% ownership stake, the smelter (Alcoa Corporation’s share of the capacity was 115 kmt-per-year) generated sales of approximately $280 in 2013 and, at the time of divestiture, had approximately 250 employees. D. Restructuring and Other Charges Restructuring and other charges for each year in the three-year period ended December 31, 2016 were comprised of the following: 2016 2015 2014 Asset impairments $155 $311 $328 Asset retirement obligations 97 76 87 Layoff costs 32 199 157 Environmental remediation 26 86 28 Legal matters in Italy (R) - 201 - Net (gain) loss on divestitures of businesses (C) (3) 25 214 Other 47 92 66 Reversals of previously recorded layoff and other exit costs (36) (7) (17) Restructuring and other charges $318 $983 $863 * In 2016, 2015, and 2014, Other includes $1, $32, and $23, respectively, related to the allocation of restructuring charges to Alcoa Corporation from ParentCo (see Note A). Layoff costs were recorded based on approved detailed action plans submitted by the operating locations that specified positions to be eliminated, benefits to be paid under existing severance plans, union contracts or statutory requirements, and the expected timetable for completion of the plans. 116 2016 Actions.In 2016, Alcoa Corporation recorded Restructuring and other charges of $318, which were comprised of the following components: $131 for exit costs related to a decision to permanently close and demolish a refinery (see below); $87 for additional net costs related to decisions made in late 2015 to permanently close and demolish the Warrick (Indiana) smelter and to curtail the Wenatchee (Washington) smelter and Point Comfort (Texas) refinery (see 2015 Actions below); $72 for the impairment of an interest in gas exploration assets in Western Australia (see below); $32 for layoff costs related to cost reduction initiatives, including the separation of approximately 75 employees (60 in the Aluminum segment and 15 in the Bauxite segment) and related pension settlement costs (see Note N); a net charge of $8 for other miscellaneous items; and a reversal of $12 associated with a number of small layoff reserves related to prior periods. In December 2016, management approved the permanent closure of the Suralco refinery (capacity of 2,207 kmt-per- year) in Suriname. The Suralco refinery had been fully curtailed since November 2015 (see 2015 Actions below). Management of ParentCo decided to curtail the remaining operating capacity of the Suralco refinery during 2015 in an effort to improve the position of ParentCo’s refining operations on the global alumina cost curve. Since that time, management of ParentCo (through October 31, 2016) and then separately management of Alcoa Corporation (from November 1, 2016 through the end of 2016) had been in discussions with the Government of the Republic of Suriname to determine the best long-term solution for Suralco due to limited bauxite reserves and the absence of a long-term energy alternative. The decision to permanently close the Suralco refinery was based on the ultimate conclusion of those discussions. Demolition and remediation activities related to this action will begin in mid-2017 and are expected to be completed by the end of 2021. The related bauxite mines in Suriname will also be permanently closed while the hydroelectric facility that supplied power to the Suralco refinery, known as Afobaka, will continue to operate and supply power to the Government of the Republic of Suriname. In 2016, costs related to the closure and curtailment actions included accelerated depreciation of $70 related to the Warrick smelter as it continued to operate through March 2016; asset impairments of $16, representing the write-off of the remaining book value of various assets; a reversal of $24 associated with severance costs initially recorded in late 2015; and $156 in other costs. Additionally in 2016, remaining inventories, mostly operating supplies and raw materials, were written down to their net realizable value, resulting in a charge of $5, which was recorded in Cost of goods sold on the accompanying Statement of Consolidated Operations. The other exit costs of $156 represent $94 in asset retirement obligations and $26 in environmental remediation, both of which were triggered by the decisions to permanently close and demolish the Suralco refinery (includes the rehabilitation of related bauxite mines) and the rehabilitation of a coal mine related to the Warrick smelter, $32 for contraction terminations, and $4 in other related costs. Also in December 2016, management of Alcoa Corporation concluded that an interest in certain gas exploration assets in Western Australia has been impaired. AofA owns an interest in a gas exploration project that was initially entered into in 2007 as a potential source of low-cost gas to supply AofA’s refineries in Western Australia. This interest, now at 43%, relates to four separate gas wells. In late 2016, AofA received the results of a technical analysis performed earlier in the year for two of the wells and an updated analysis for a third well that concluded that the cost of gas recovery would be significantly higher than the market price of gas. For the fourth well, the results of a technical analysis performed prior to 2016 indicated that the cost of gas recovery would be lower than the market price of gas and, therefore, would require additional investment to move to the next phase of commercial evaluation, which management previously supported. In late 2016, management re-evaluated its options related to the fourth well and decided it is not economical to make such a commitment for the foreseeable future. As a result, AofA fully impaired its $72 interest. As of December 31, 2016, approximately 55 of the 75 employees were separated. The remaining separations for 2016 restructuring programs are expected to be completed by the end of 2017. In 2016, cash payments of $7 were made against layoff reserves related to 2016 restructuring programs. 2015 Actions.In 2015, Alcoa Corporation recorded Restructuring and other charges of $983, which were comprised of the following components: $418 for exit costs related to decisions to permanently close and demolish three smelters 117 and a power station (see below); $238 for the curtailment of two refineries and two smelters (see below); $201 related to legal matters in Italy (see Note R); a $24 net loss primarily related to post-closing adjustments associated with two December 2014 divestitures (see Note C); $45 for layoff costs, including the separation of approximately 465 employees; $33 for asset impairments related to prior capitalized costs for an expansion project at a refinery in Australia that is no longer being pursued; a net credit of $1 for other miscellaneous items; a reversal of $7 associated with a number of small layoff reserves related to prior periods; and $32 related to Corporate restructuring allocated to Alcoa Corporation (see Note A). During 2015, management initiated various alumina refining and aluminum smelting capacity curtailments and/or closures. The curtailments were composed of the remaining capacity at all of the following: the São Luís smelter in Brazil (74 kmt-per-year); the Suriname refinery (1,330 kmt-per-year); the Point Comfort refinery (2,010 kmt-per-year); and the Wenatchee smelter (143 kmt-per-year). All of the curtailments were completed in 2015 except for 1,635 kmt- per-year at the Point Comfort refinery, which was completed by the end of June 2016. The permanent closures were composed of the capacity at the Warrick smelter (269 kmt-per-year) (includes the closure of a related coal mine) and the infrastructure of the Massena East (New York) smelter (potlines were previously shut down in both 2013 and 2014—see 2014 Actions below), as the modernization of this smelter is no longer being pursued. The closure of the Warrick smelter was completed by the end of March 2016. The decisions on the above actions were part of a separate 12-month review in refining (2,800 kmt-per-year) and smelting (500 kmt-per-year) capacity initiated by management in March 2015 for possible curtailment (partial or full), permanent closure or divestiture. While many factors contributed to each decision, in general, these actions were initiated to maintain competitiveness amid prevailing market conditions for both alumina and aluminum. Separate from the actions initiated under the reviews described above, in mid-2015, management approved the permanent closure and demolition of the Poços de Caldas smelter (capacity of 96 kmt-per-year) in Brazil and the Anglesea power station (includes the closure of a related coal mine) in Australia. The entire capacity at Poços de Caldas had been temporarily idled since May 2014 and the Anglesea power station was shut down at the end of August 2015. Demolition and remediation activities related to the Poços de Caldas smelter and the Anglesea power station began in late 2015 and are expected to be completed by the end of 2026 and 2020, respectively. The decision on the Poços de Caldas smelter was due to management’s conclusion that the smelter was no longer competitive as a result of challenging global market conditions for primary aluminum, which led to the initial curtailment, that have not dissipated and higher costs. For the Anglesea power station, the decision was made because a sale process did not result in a sale and there would have been imminent operating costs and financial constraints related to this site in the remainder of 2015 and beyond, including significant costs to source coal from available resources, necessary maintenance costs, and a depressed outlook for forward electricity prices. The Anglesea power station previously supplied approximately 40 percent of the power needs for the Point Henry smelter, which was closed in August 2014 (see 2014 Actions below). In 2015, costs related to the closure and curtailment actions included asset impairments of $226, representing the write- off of the remaining book value of all related properties, plants, and equipment; $154 for the layoff of approximately 3,100 employees (1,800 in the former Primary Metals segment and 1,300 in the former Alumina segment—see Note E), including $30 in pension costs (see Note N); accelerated depreciation of $85 related to certain facilities as they continued to operate during 2015; and $222 in other exit costs. Additionally in 2015, remaining inventories, mostly operating supplies and raw materials, were written down to their net realizable value, resulting in a charge of $90, which was recorded in Cost of goods sold on the accompanying Statement of Combined Operations. The other exit costs of $222 represent $72 in asset retirement obligations and $85 in environmental remediation, both of which were triggered by the decisions to permanently close and demolish the aforementioned structures in the United States, Brazil, and Australia (includes the rehabilitation of a related coal mine in each of Australia and the United States), and $65 in supplier and customer contract-related costs. 118 As of December 31, 2016, approximately 3,200 of the 3,400 (previously 3,600) employees were separated. The total number of employees associated with 2015 restructuring programs was updated to reflect employees, who were initially identified for separation, accepting other positions within ParentCo and natural attrition. The remaining separations for 2015 restructuring programs are expected to be completed by mid-2017. In 2016 and 2015, cash payments of $65 and $26, respectively, were made against layoff reserves related to 2015 restructuring programs. 2014 Actions.In 2014, Alcoa Corporation recorded Restructuring and other charges of $863, which were comprised of the following components: $526 for exit costs related to decisions to permanently shut down and demolish three smelters (see below); a $216 net loss for the divestitures of three operations (see Note C); $61 for the temporary curtailment of two smelters and a related production slowdown at one refinery (see below); $33 for asset impairments related to prior capitalized costs for a modernization project at a smelter in Canada that is no longer being pursued; $9 for layoff costs, including the separation of approximately 60 employees; a net charge of $4 for an environmental charge at a previously shut down refinery; $9 primarily for the reversal of a number of layoff reserves related to prior periods; and $23 related to Corporate restructuring allocated to Alcoa Corporation (see Note A). In early 2014, management approved the permanent closure and demolition of the remaining capacity (84 kmt-per- year) at the Massena East smelter and the full capacity (190 kmt-per-year) at the Point Henry smelter in Australia. The capacity at Massena East was fully shut down by the end of March 2014 and the Point Henry smelter was fully shut down in August 2014. Demolition and remediation activities related to both the Massena East and Point Henry smelters began in late 2014 and are expected to be completed by the end of 2020 and 2018, respectively. The decisions on the Massena East and Point Henry smelters were part of a 15-month review of 460,000 metric tons of smelting capacity initiated by management in May 2013 for possible curtailment. Through this review, management determined that the remaining capacity of the Massena East smelter was no longer competitive and the Point Henry smelter had no prospect of becoming financially viable. Management also initiated the temporary curtailment of the remaining capacity (62 kmt-per-year) at the Poços de Caldas smelter and additional capacity (85 kmt-per-year) at the São Luís smelter. These curtailments were completed by the end of May 2014. As a result of these curtailments, 200 kmt-per-year of production at the Poços de Caldas refinery was reduced by the end of June 2014. Additionally, in August 2014, management approved the permanent closure and demolition of the capacity (150 kmt- per-year) at the Portovesme smelter in Italy, which had been idle since November 2012. This decision was made because the fundamental reasons that made the Portovesme smelter uncompetitive remained unchanged, including the lack of a viable long-term power solution. Demolition and remediation activities related to the Portovesme smelter began in 2016 and are expected to be completed by the end of 2022 (delayed due to discussions with the Italian government and other stakeholders). In 2014, costs related to the closure and curtailment actions included $149 for the layoff of approximately 1,290 employees, including $24 in pension costs (see Note N); accelerated depreciation of $146 related to the Point Henry smelter in Australia as they continued to operate during 2014; asset impairments of $150 representing the write-off of the remaining book value of all related properties, plants, and equipment; and $152 in other exit costs. Additionally in 2014, remaining inventories, mostly operating supplies and raw materials, were written down to their net realizable value, resulting in a charge of $55, which was recorded in Cost of goods sold on the accompanying Statement of Combined Operations. The other exit costs of $152 represent $87 in asset retirement obligations and $24 in environmental remediation, both of which were triggered by the decisions to permanently close and demolish the aforementioned structures in Australia, Italy, and the United States, and $41 in other related costs, including supplier and customer contract-related costs. As of March 31, 2016, the separations associated with 2014 restructuring programs were essentially complete. In 2016 and 2015, cash payments of $1 and $34, respectively, were made against layoff reserves related to 2014 restructuring programs. 119 Alcoa Corporation does not include Restructuring and other charges in the results of its reportable segments. The impact of allocating such charges to segment results would have been as follows: 2016 2015 2014 Bauxite $18 $16 $ - Alumina 182 212 283 Aluminum 96 610 559 Cast Products (1) 2 (2) Energy 23 84 - Rolled Products -9- Segment total 318 933 840 Corporate -5023 Total restructuring and other charges $318 $983 $863 Activity and reserve balances for restructuring charges were as follows: Layoff costs Other exit costs Total Reserve balances at December 31, 2013 $ 58 $ 14 $ 72 2014: Cash payments (120) (7) (127) Restructuring charges 138 158 296 Other*(26) (152) (178) Reserve balances at December 31, 2014 50 13 63 2015: Cash payments (65) (1) (66) Restructuring charges 199 423 622 Other*(47) (420) (467) Reserve balances at December 31, 2015 137 15 152 2016: Cash payments (74) (35) (109) Restructuring charges 32 168 200 Other*(57) (120) (177) Reserve balances at December 31, 2016 $ 38 $ 28 $ 66 * Other includes reversals of previously recorded restructuring charges and the effects of foreign currency translation. In 2016, 2015, and 2014, Other for layoff costs also included a reclassification of $16, $35, and $24, respectively, in pension and/or other postretirement benefits costs, as these obligations were included in Alcoa Corporation’s separate liability for pension and other postretirement benefits obligations (see Note N). Additionally in 2016, 2015, and 2014, Other for other exit costs also included a reclassification of the following restructuring charges: $97, $76, and $87, respectively, in asset retirement and $26, $86, and $28, respectively, in environmental obligations, as these liabilities were included in Alcoa Corporation’s separate reserves for asset retirement obligations (see Note Q) and environmental remediation (see Note R). The remaining reserves are expected to be paid in cash during 2017, with the exception of approximately $5, which is expected to be paid by no later than the end of 2019 for contract termination and special layoff benefit payments. 120 E. Segment and Geographic Area Information Segment Information Alcoa Corporation is a producer of bauxite, alumina, primary aluminum, and aluminum sheet and the Company’s segments are organized by product on a worldwide basis. Segment performance under Alcoa Corporation’s management reporting system is evaluated based on a number of factors; however, the primary measure of performance is the after-tax operating income (ATOI) of each segment. Certain items such as the impact of LIFO inventory accounting; metal price lag; interest expense; noncontrolling interest; corporate expense (general administrative and selling expenses of operating the corporate headquarters and other global administrative facilities, along with depreciation and amortization on corporate-owned assets); restructuring and other charges; income taxes, including the impact of any discrete tax items, deferred tax valuation allowance adjustments, and other differences between tax rates applicable to the segments and the consolidated effective tax rate; and intersegment profit elimination and other nonoperating items such as foreign currency transaction gains/losses, gains/losses on certain asset sales, and interest income are excluded from segment ATOI. Segment assets exclude, among others, cash and cash equivalents; LIFO reserves; corporate fixed assets; goodwill not allocated to businesses for segment reporting purposes; deferred income taxes; and certain derivative contracts. The accounting policies of the segments are the same as those described in the Summary of Significant Accounting Policies (see Note B). Transactions among segments are established based on negotiation among the parties. Differences between segment totals and Alcoa Corporation’s consolidated totals for line items not reconciled are in Corporate. Effective January 1, 2015, Alcoa Corporation redefined its segments concurrent with an internal reorganization for certain of its businesses. Following this reorganization, Alcoa Corporation’s operations consist of six reportable segments as follows: Bauxite.This segment represents Alcoa Corporation’s global portfolio of bauxite mining assets. Bauxite is mined and sold primarily to internal customers within the Alumina segment, who then process it into alumina. A portion of this segment’s production is also sold to third parties. Bauxite is transferred to the Alumina segment at negotiated terms that are intended to approximate market prices; sales to third parties are conducted on a contract basis. Alumina.This segment represents Alcoa Corporation’s worldwide refining system, which processes bauxite into alumina, which is mainly sold directly to internal and external smelter customers worldwide, or is sold to customers who process it into industrial chemical products. More than half of Alumina’s production is sold under supply contracts to third parties worldwide, while the remainder is used internally by the Aluminum segment. Alumina produced by this segment and used internally is transferred to the Aluminum segment at prevailing market prices. A portion of this segment’s third-party sales are completed through the use of agents, alumina traders, and distributors. Aluminum.This segment represents Alcoa Corporation’s worldwide smelter system. Aluminum receives alumina, mostly from the Alumina segment, and produces molten primary aluminum. Virtually all of Aluminum’s production is sold internally to the Cast Products or Rolled Products segment, and is transferred at prevailing market prices. Cast Products.This segment represents Alcoa Corporation’s worldwide cast house system. Cast products are made from molten aluminum, purchased primarily from Alcoa Corporation’s Aluminum segment, which is then formed into various value-add ingot products, including billet and slab, for use in fabrication operations in a variety of industries. Results from the sale of aluminum powder and scrap are also included in this segment. The majority of this segment’s products are sold to third parties, including to Arconic’s aluminum fabrication businesses; the remaining portion is sold to the Rolled Products segment at prevailing market prices. Energy.This segment represents Alcoa Corporation’s portfolio of energy assets, with power production capacity of approximately 1,685 megawatts. This power is sold to both internal customers within the Aluminum segment and external customers, and provides operational flexibility to maximize operating results during market cyclicality. 121 Rolled Products.This segment represents Alcoa Corporation’s rolling mill in Warrick, Indiana, which produces aluminum sheet primarily sold directly to customers in the packaging end market for the production of aluminum cans (beverage, food, and pet food). Additionally, Alcoa Corporation has a tolling arrangement with Arconic whereby Arconic’s rolling mill in Tennessee produces can sheet products for certain of this segment’s customers. Alcoa Corporation supplies all of the raw materials to the Tennessee facility and pays Arconic for the tolling service. Depending on certain factors, this arrangement concludes at the end of 2018. Seasonal increases in can sheet sales are generally experienced in the second and third quarters of the year. This segment also includes Alcoa Corporation’s investment in a rolling mill in Saudi Arabia (see Note H). Under the applicable reporting guidance, when a Company changes its organizational structure, it should generally prepare its segment information based on the new segments and provide comparative information for related periods. However, in certain instances, changes to the structure of an internal organization could change the composition of its reportable segments and it may not be practical to retrospectively revise prior periods. In connection with the January 1, 2015 reorganization, Alcoa Corporation fundamentally altered the commercial nature of how certain internal businesses transact with each other, moving from a cost-based transfer pricing model to one based on estimated market pricing. As a result, certain operations (e.g., bauxite mining, smelting and casting) that had previously been measured and evaluated primarily based on costs incurred were transformed into separate businesses with full profit and loss information. In addition, this reorganization involved converting regional-based management responsibility to global responsibility for each business, which had a further impact on overall cost structures of the segments. As a result of the significant changes associated with the reorganization (including substantial information system modifications), which were implemented on a prospective basis only, Alcoa Corporation does not have all of the information that would be necessary to present certain segment data, specifically ATOI, income taxes and total assets, for periods prior to 2015. This information is not available to Alcoa Corporation management for its own internal use, and it is impracticable to obtain or generate this information, as underlying commercial transactions between the segments, which are necessary to determine these income-based and asset-based segment measures, did not take place prior to 2015. The operating results and assets of Alcoa Corporation’s reportable segments were as follows: Bauxite Alumina Aluminum Cast Products Energy Rolled Products Total 2016 Sales: Third-party sales—unrelated party $ 315 $2,300 $ 9 $4,244 $ 279 $1,069 $ 8,216 Third-party sales—related party - - - 957 1 - 958 Intersegment sales 751 1,307 3,754 316 168 - 6,296 Total sales $1,066 $3,607 $3,763 $5,517 $ 448 $1,069 $15,470 Profit and loss: Equity (loss) income $ - $ (40) $ 23 $ (7) $ - $ (40) $ (64) Depreciation, depletion, and amortization 77 186 295 42 57 23 680 Income taxes 87 37 (60) 60 26 (17) 133 ATOI 212 102 (19) 176 76 (41) 506 2015 Sales: Third-party sales—unrelated party $ 71 $3,343 $ 13 $5,127 $ 416 $ 985 $ 9,955 122 Bauxite Alumina Aluminum Cast Products Energy Rolled Products Total Third-party sales—related party - - 1 1,059 10 8 1,078 Intersegment sales 1,160 1,687 5,092 46 297 - 8,282 Total sales $1,231 $5,030 $5,106 $6,232 $ 723 $ 993 $19,315 Profit and loss: Equity (loss) income $ - $ (41) $ 25 $ (37) $ - $ (32) $ (85) Depreciation, depletion, and amortization 94 202 311 42 61 23 733 Income taxes 103 191 (77) 49 69 26 361 ATOI 258 476 1 110 145 20 1,010 2014 Sales: Third-party sales—unrelated party $ 41 $3,413 $ 21 $6,069 $ 682 $1,008 $11,234 Third-party sales—related party(1)- - - 1,758 - 25 1,783 Intersegment sales (1)1,106 1,941 6,221 262 663 - 10,193 Total sales $1,147 $5,354 $6,242 $8,089 $1,345 $1,033 $23,210 Profit and loss: Equity loss $ - $ (29) $ (34) $ - $ - $ (27) $ (90) Depreciation, depletion, and amortization 120 201 365 47 68 24 825 Income taxes * * * * * 27 * ATOI * * * * * 21 * 2016 Assets: Capital expenditures $ 29 $ 109 $ 125 $ 31 $ 6 $ 94 $ 394 Equity investments 163 342 520 - 164 175 1,364 Goodwill 2 4 - - - - 6 Total assets 1,541 4,791 5,182 816 1,216 848 14,394 2015 Assets: Capital expenditures $ 30 $ 154 $ 108 $ 32 $ 16 $ 52 $ 392 Equity investments 164 503 497 - 137 217 1,518 Goodwill 2 4 - - - - 6 Total assets 1,443 4,721 5,612 578 1,218 637 14,209 (1)Amounts were estimated by Alcoa Corporation’s management in an effort to provide comparable revenue information for 2014. * This information is not available for periods prior to 2015 and is impracticable to obtain.

Prior to January 1, 2015, Alcoa Corporation’s operations consisted of three reportable segments, as follows: Alumina.This segment represented Alcoa Corporation’s worldwide refining system, and primarily comprised the combined Bauxite and Alumina segments that were established on January 1, 2015, described above. This segment encompassed the mining of bauxite, from which alumina is produced and sold directly to external smelter customers, as well as to the previous Primary Metals segment (see below), or to customers who process it into industrial chemical products. More than half of Alumina’s production was sold under supply contracts to third parties worldwide, while the remainder was used internally by the Primary Metals segment. Alumina produced by this segment and used internally was transferred to the Primary Metals segment at prevailing market prices. A portion of this segment’s third-party sales was completed through the use of agents, alumina traders, and distributors. Primary Metals.This segment represented Alcoa Corporation’s worldwide smelting system and associated cast houses, and primarily comprised the Aluminum and Cast Products segments that were established on January 1, 2015, described above. The majority of the power generation assets in the Energy segment that was established on January 1, 2015 were also included in Primary Metals. The Primary Metals segment purchased alumina, mostly from the former Alumina segment, from which primary aluminum was produced and then sold directly to external customers and traders, as well as to the Rolled Products segment and ParentCo’s aluminum fabrication businesses. Results from the sale of aluminum 124 powder, scrap, and excess energy were also included in this segment. Primary aluminum produced by this segment and used by the Rolled Products segment or by ParentCo’s aluminum fabrication businesses was transferred at prevailing market prices. The sale of primary aluminum represented approximately 90% of this segments third-party sales. Rolled Products.This segment represents Alcoa Corporation’s rolling mill in Warrick, Indiana, which produces aluminum sheet primarily sold directly to customers in the packaging end market for the production of aluminum cans (beverage, food, and pet food). Seasonal increases in can sheet sales are generally experienced in the second and third quarters of the year. This segment also includes Alcoa Corporation’s investment in a rolling mill in Saudi Arabia (see Note H). The operating results and assets of Alcoa Corporation’s reportable segments under the historical presentation format were as follows: Alumina Primary Metals Rolled Products Total 2015 Sales: Third-party sales—unrelated party $3,455 $5,667 $ 985 $10,107 Third-party sales—related party - 1,070 8 1,078 Intersegment sales 1,687 532 - 2,219 Total sales $5,142 $7,269 $ 993 $13,404 Profit and loss: Equity loss $ (41) $ (12) $ (32) $ (85) Depreciation, depletion, and amortization 296 429 23 748 Income taxes 300 (20) 26 306 ATOI 746 136 20 902 2014 Sales: Third-party sales—unrelated party $3,509 $6,843 $1,008 $11,360 Third-party sales—related party - 1,758 25 1,783 Intersegment sales 1,941 614 - 2,555 Total sales $5,450 $9,215 $1,033 $15,698 Profit and loss: Equity loss $ (29) $ (34) $ (27) $ (90) Depreciation, depletion, and amortization 387 494 24 905 Income taxes 153 214 27 394 ATOI 370 627 21 1,018 2015 Assets: Capital expenditures $ 184 $ 156 $ 52 $ 392 Equity investments 667 634 217 1,518 Goodwill 6 - - 6 Total assets 6,165 7,134 637 13,936 125 The following tables reconcile certain segment information under the historical presentation format to consolidated totals: 2015 2014 Sales: Total segment sales $13,404 $15,698 Elimination of intersegment sales (2,219) (2,555) Other 14 4 Consolidated sales $11,199 $13,147 2015 2014 Net loss attributable to Alcoa Corporation: Total segment ATOI $ 902 $1,018 Unallocated amounts: Impact of LIFO 107 4 Metal price lag (30) 15 Interest expense (270) (309) Noncontrolling interest (net of tax) (124) 91 Corporate expense (180) (208) Restructuring and other charges (983) (863) Income taxes (96) 110 Other (189) (114) Consolidated net loss attributable to Alcoa Corporation $(863) $ (256) December 31,2015 Assets: Total segment assets $13,936 Elimination of intersegment receivables (306) Unallocated amounts: Cash and cash equivalents 557 Deferred income taxes 589 Corporate goodwill 147 Corporate fixed assets, net 454 LIFO reserve (172) Fair value of derivative contracts 1,078 Other 130 Consolidated assets $16,413 Geographic Area Information Geographic information for sales was as follows (based upon the country where the point of sale occurred): 2016 2015 2014 Sales: United States(1)$4,365 $ 5,386 $ 6,096 Spain(2)2,663 2,852 3,198 Australia 1,644 2,147 2,656 Brazil 432 562 1,025 Canada 141 132 18 Other 73 120 154 $9,318 $11,199 $13,147 126 (1)Sales of a portion of the alumina from Alcoa Corporation’s refineries in Suriname, Brazil, Australia, and Jamaica (prior to divestiture—see Note C) and most of the aluminum from Alcoa Corporation’s smelters in Canada occurred in the United States. (2)In all periods presented, sales of the aluminum produced from Alcoa Corporation’s smelters in Iceland and Norway, as well as Alcoa Corporation’s off-take related to its interest in the Saudi Arabia joint venture (see Note H), occurred in Spain.

Earnings Per Share Basic earnings per share (EPS) amounts are computed by dividing earnings by the average number of common shares outstanding. Diluted EPS amounts assume the issuance of common stock for all potentially dilutive share equivalents outstanding. The information used to compute basic and diluted EPS attributable to Alcoa Corporation common shareholders was as follows (shares in millions): 2016 2015 2014 Net loss attributable to Alcoa Corporation $(400) $(863) $(256) Average shares outstanding—basic 183 182 182 Effect of dilutive securities: Stock options --- Stock and performance awards - - - Average shares outstanding—diluted 183 182 182 In 2016, basic average shares outstanding and diluted average shares outstanding were the same because the effect of potential shares of common stock was anti-dilutive since Alcoa Corporation generated a net loss. As a result, 1 million stock awards and stock options combined were not included in the computation of diluted EPS. Had Alcoa Corporation generated net income in 2016, 1 million potential shares of common stock related to stock awards and stock options combined would have been included in diluted average shares outstanding. In 2015 and 2014, the EPS included on the accompanying Statement of Consolidated Operations was calculated based on the 182,471,195 shares of Alcoa Corporation common stock distributed on the Separation Date in conjunction with the completion of the Separation Transaction (see Note A) and is considered pro forma in nature. Prior to November 1, 2016, Alcoa Corporation did not have any issued and outstanding common stock. Options to purchase 1 million shares of common stock at a weighted average exercise price of $33.05 per share were outstanding as of December 31, 2016, but were not included in the computation of diluted EPS because they were anti- dilutive, as the exercise prices of the options were greater than the average market price of Alcoa Corporation’s common stock. 127 G.

Specifically, the project developed by the joint venture consists of: (i) a bauxite mine for the extraction of approximately 4,000 kmt of bauxite from the Al Ba’itha bauxite deposit near Quiba in the northern part of Saudi Arabia; (ii) an alumina refinery with an initial capacity of 1,800 kmt; (iii) a primary aluminum smelter with an initial capacity of 740 kmt; and (iv) a rolling mill with an initial capacity of 380 kmt. The refinery, smelter, and rolling mill were constructed in an industrial area at Ras Al Khair on the east coast of Saudi Arabia. The facilities use critical infrastructure, including power generation derived from reserves of natural gas, as well as port and rail facilities, developed by the government of Saudi Arabia. First production from the smelter, rolling mill, and mine and refinery occurred in December of 2012, 2013, and 2014, respectively. In 2012, Alcoa Corporation and Ma’aden agreed to expand the capabilities of the rolling mill to include a capacity of 100 kmt dedicated to supplying aluminum automotive, building and construction, and foil stock sheet. First production related to the expanded capacity occurred in 2014. This expansion did not result in additional equity investment (see below) due to significant savings from a change in the project execution strategy of the initial 380 kmt capacity of the rolling mill. The joint venture is owned 74.9% by Ma’aden and 25.1% by Alcoa Corporation and consists of three separate companies as follows: one each for the mine and refinery, the smelter, and the rolling mill. The Alcoa Corporation affiliates that hold Alcoa Corporation’s interests in the smelting company and the rolling mill company are indirectly wholly owned by Alcoa Corporation, and the Alcoa Corporation affiliate that holds Alcoa Corporation’s interests in the mining and refining company is wholly owned by AWAC. Except in limited circumstances, Alcoa Corporation may not sell, transfer or otherwise dispose of or encumber or enter into any agreement in respect of the votes or other rights attached to its interests in the joint venture without Ma’aden’s prior written consent. Ma’aden and Alcoa Corporation have put and call options, respectively, whereby Ma’aden can require Alcoa Corporation to purchase from Ma’aden, or Alcoa Corporation can require Ma’aden to sell to Alcoa Corporation, a 14.9% interest in the joint venture at the then fair market value. These options may only be exercised in a six-month window that opens five years after the Commercial Production Date (as defined in the joint venture shareholders’ agreement) and, if exercised, must be exercised for the full 14.9% interest. The Commercial Production Date was declared on September 1, 2014 for the smelting company and on October 1, 2016 for the mining and refining company. There has not been a similar declaration yet for the rolling mill company. Ma’aden and Alcoa Corporation also may not sell, transfer, or otherwise dispose of, pledge, or encumber any interests in the joint venture until five years after the Commercial Production Date. Under the joint venture shareholders’ agreement, upon the occurrence of an unremedied event of default by Alcoa Corporation, Ma’aden may purchase, or, upon the occurrence of an unremedied event of default by Ma’aden, Alcoa Corporation may sell, its interest for consideration that varies depending on the time of the default. 131 A number of Alcoa Corporation employees perform various types of services for the smelting, rolling mill, and refining and mining companies as part of the operation of the fully-integrated aluminum complex. At December 31, 2016 and 2015, Alcoa Corporation had an outstanding receivable of $11 and $19, respectively, from the smelting, rolling mill, and refining and mining companies for labor and other employee-related expenses. Capital investment in the project is expected to total approximately $10,800 (SAR 40.5 billion) and has been funded through a combination of equity contributions by the joint venture partners and project financing by the joint venture, which has been guaranteed by both partners (see below). Both the equity contributions and the guarantees of the project financing are based on the joint venture’s partners’ ownership interests. Originally, it was estimated that Alcoa Corporation’s total equity contribution in the joint venture would be approximately $1,100, of which Alcoa Corporation has contributed $982, including $1 and $29 in 2016 and 2015, respectively. Based on changes to both the project’s capital investment and equity and debt structure from the initial plans, the estimated $1,100 equity contribution may be reduced. As of December 31, 2016 and 2015, the carrying value of Alcoa Corporation’s investment in this project was $853 and $928, respectively. The smelting and rolling mill companies have project financing totaling $4,133 (reflects principal payments made through December 31, 2016), of which $1,037 represents Alcoa Corporation’s share (the equivalent of Alcoa Corporation’s 25.1% interest in the smelting and rolling mill companies). Alcoa Corporation has issued guarantees (see below) on behalf of the smelting and rolling mill companies to the lenders in the event that such companies default on their debt service requirements through 2017 and 2020 for the smelting company and 2018 and 2021 for the rolling mill company (Ma’aden issued similar guarantees for its 74.9% interest). Alcoa Corporation’s guarantees for the smelting and rolling mill companies cover total debt service requirements of $100 in principal and up to a maximum of approximately $35 in interest per year (based on projected interest rates). At December 31, 2016 and 2015, the combined fair value of the guarantees was $3 and $7, respectively, which was included in Other noncurrent liabilities and deferred credits on the accompanying Consolidated Balance Sheet. The mining and refining company has project financing totaling $2,232, of which $560 represents AWAC’s 25.1% interest in the mining and refining company. Alcoa Corporation, on behalf of AWAC, has issued guarantees (see below) to the lenders in the event that the mining and refining company defaults on its debt service requirements through 2019 and 2024 (Ma’aden issued similar guarantees for its 74.9% interest). Alcoa Corporation’s guarantees for the mining and refining company cover total debt service requirements of $120 in principal and up to a maximum of approximately $30 in interest per year (based on projected interest rates). At both December 31, 2016 and 2015, the combined fair value of the guarantees was $3, which was included in Other noncurrent liabilities and deferred credits on the accompanying Consolidated Balance Sheet. In the event Alcoa Corporation would be required to make payments under the guarantees, 40% of such amount would be contributed to Alcoa Corporation by Alumina Limited, consistent with its ownership interest in AWAC. As a result of the Separation Transaction, the various lenders to the joint venture companies required Arconic to maintain joint and several guarantees with Alcoa Corporation. In the event of default by any of the joint venture companies, the lenders would make a claim against both Alcoa Corporation and Arconic. Accordingly, Alcoa Corporation would perform under its guarantee; however, if the Company failed to perform, Arconic would be required to perform under its own guarantee. Arconic would then subsequently seek indemnification from Alcoa Corporation under the terms of the Separation and Distribution Agreement. In June 2013, all three joint venture companies entered into a 20-year gas supply agreement with Saudi Aramco. The gas supply agreement provides sufficient fuel to meet manufacturing process requirements as well as fuel to the adjacent combined water and power plant constructed by Saline Water Conversion Corporation, which is owned by the government of Saudi Arabia and is responsible for desalinating sea water and producing electricity for Saudi Arabia. The combined water and power plant converts the three joint venture companies’ gas into electricity and water at cost, which is supplied to the refinery, smelter, and rolling mill. A $60 letter of credit previously provided to the Ministry of Petroleum and Mineral Resources of Saudi Arabia by Ma’aden (Alcoa Corporation is responsible for its pro rata share) under the gas allocation was terminated in June 2015 due to the completion of certain auxiliary rolling facilities. 132 DBNGP Trust—In 2004, AofA acquired a 20% interest in a consortium, which subsequently purchased the DBNGP in Western Australia, in exchange for an initial cash investment of $17 (A$24). The investment in the DBNGP was made in order to secure a competitively priced long-term supply of natural gas to AofA’s refineries in Western Australia. AofA made additional contributions of $141 (A$176) for its share of the pipeline capacity expansion and other operational purposes of the consortium through September 2011. In late 2011, the consortium initiated a three- year equity call plan to improve its capitalization structure. This plan required AofA to contribute $39 (A$40), all of which was made through December 31, 2014. Following the completion of the three-year equity call plan in December 2014, the consortium initiated a new equity call plan to further improve its capitalization structure. This plan required AofA to contribute $30 (A$36) through mid-2016, of which $20 (A$27) was made through March 31, 2016, including $3 (A$5) and $16 (A$21) in 2016 and 2015, respectively. In April 2016, AofA sold its 20% interest in the consortium, effectively terminating its remaining obligation to make contributions under the most recent equity call plan, to the only other member of the consortium, DUET Group. AofA received $145 (A$192) in cash, which was included in Sales of investments on the accompanying Statement of Consolidated Cash Flows, and recorded a gain of $27 (A$35) ($11 (A$15) after-tax and noncontrolling interest) in Other income, net on the accompanying Statement of Consolidated Operations. As part of the sale transaction, AofA will maintain its current access to approximately 30% of the DBNGP transmission capacity for gas supply to its three alumina refineries in Western Australia under an existing agreement to purchase gas transmission services from the DBNGP. At December 31, 2016 and 2015, AofA has an asset of $270 (A$375) and $268 (A$368), respectively, representing prepayments made under the agreement for future gas transmission services. I.

Also, as of December 31, 2016 and 2015, the net carrying value of temporarily idled refining assets was $158 and $53, representing 2,305 kmt and 2,801 kmt of idle capacity, respectively. At the end of 2016, Alcoa Corporation permanently closed 2,207 kmt of refining capacity, of which 2,131 kmt was included in the 2,801 kmt of idle capacity as of December 31, 2015. 134 K. Goodwill and Other Intangible Assets The following table details the changes in the carrying amount of goodwill: Bauxite Alumina Corporate* Total Balance at December 31, 2014: Goodwill $ 3 $ 5 $152 $160 Accumulated impairment losses - - - - 3 5 152 160 Translation (1) (1) (6) (8) Balance at December 31, 2015: Goodwill 2 4 146 152 Accumulated impairment losses - - - - 2 4 146 152 Translation - - 3 3 Balance at December 31, 2016: Goodwill 2 4 149 155 Accumulated impairment losses - - - - $ 2 $ 4 $149 $155 * As of December 31, 2016, the $149 of goodwill reflected in Corporate is allocated to two of Alcoa Corporation’s six reportable segments ($50 to Bauxite and $99 to Alumina) included in the table above for purposes of impairment testing (see Note B). This goodwill is reflected in Corporate for segment reporting purposes because it is not included in management’s assessment of performance by the two reportable segments. There is no goodwill associated with Alcoa Corporation’s other four reportable segments. Other intangible assets, which are included in Other noncurrent assets on the accompanying Consolidated Balance Sheet, were as follows: 2016 2015 December 31, Gross carrying amount Accumulated amortization Gross carrying amount Accumulated amortization Computer software* $252 $(196) $176 $(158) Patents and licenses** 70 (6) 25 (5) Other intangibles 21 (6) 25 (10) Total other intangible assets $343 $(208) $226 $(173) * As of December 31, 2016, Computer software includes amounts related to the establishment of Alcoa Corporation’s own enterprise business solution (EBS) separate from ParentCo. ** As of December 31, 2016, Patents and licenses include amounts related to the capitalization of costs associated with the renewal of Alcoa Corporation’s FERC (Federal Energy Regulatory Commission) license at its Yadkin Hydroelectric Project (see Note C). Computer software consists primarily of software costs associated with an EBS within Alcoa Corporation to drive common systems among all businesses. Amortization expense related to the intangible assets in the tables above for the years ended December 31, 2016, 2015, and 2014 was $7, $10, and $13, respectively, and is expected to be approximately $10 annually from 2017 to 2021. 135 L.

The principal amount of long-term debt maturing in each of the next five years is $21 in 2017, $19 in 2018, and $18 in each of 2019, 2020, and 2021. 144A Debt—In September 2016, Alcoa Nederland Holding B.V. (ANHBV), a wholly-owned subsidiary of Alcoa Corporation, completed a Rule 144A (U.S. Securities Act of 1933, as amended) debt offering for $750 of 6.75% Senior Notes due 2024 (the “2024 Notes”) and $500 of 7.00% Senior Notes due 2026 (the “2026 Notes” and, collectively with the 2024 Notes, the “Notes”). ANHBV received $1,228 in net proceeds (see below) from the debt offering reflecting a discount to the initial purchasers of the Notes. The net proceeds were used to make a payment to ParentCo to fund the transfer of certain assets from ParentCo to Alcoa Corporation in connection with the Separation Transaction (see Note A), and the remaining net proceeds were used for general corporate purposes. The discount to the initial purchasers, as well as costs to complete the financing, was deferred and is being amortized to interest expense over the respective terms of the Notes. Interest on the Notes will be paid semi-annually in March and September, commencing March 31, 2017. ANBHV has the option to redeem the Notes on at least 30 days, but not more than 60 days, prior notice to the holders of the Notes under multiple scenarios, including, in whole or in part, at any time or from time to time after September 2019, in the case of the 2024 Notes, or after September 2021, in the case of the 2026 Notes, at a redemption price specified in the indenture (up to 105.063% of the principal amount for the 2024 Notes and up to 103.500% of the principal amount of the 2026 Notes, plus any accrued and unpaid interest in each case). Also, the Notes are subject to repurchase upon the occurrence of a change in control repurchase event (as defined in the indenture) at a repurchase price in cash equal to 101% of the aggregate principal amount of the Notes repurchased, plus any accrued and unpaid interest on the Notes repurchased. The Notes are senior unsecured obligations of ANHBV and do not entitle the holders to any registration rights pursuant to a registration rights agreement. ANHBV does not intend to file a registration statement with respect to resales of or an exchange offer for the Notes. The Notes are guaranteed on a senior unsecured basis by Alcoa Corporation and its subsidiaries that are guarantors under the Revolving Credit Agreement described below (the “subsidiary guarantors” and, together with Alcoa Corporation, the “guarantors”). Each of the subsidiary guarantors will be released from their Notes guarantees upon the occurrence of certain events, including the release of such guarantor from its obligations as a guarantor under the Revolving Credit Agreement. The Notes indenture contains various restrictive covenants similar to those described below for the Revolving Credit Agreement, including a limitation on restricted payments, with, among other exceptions, capacity to pay annual dividends generally consistent with those provided for in the Revolving Credit Agreement, with annual capacity to pay $75 in each year within the 2021 through 2024 timeframe. 136 In conjunction with this debt offering, the net proceeds of $1,228, plus an additional $81 of ParentCo cash on hand, were required to be placed in escrow contingent on completion of the Separation Transaction. The $81 represented the necessary cash to fund the redemption of the Notes, pay all regularly scheduled interest on the Notes through a specified date as defined in the indenture, and a premium on the principal of the Notes if the Separation Transaction had not been completed by a certain time as defined in the indenture. As a result, the $1,228 of escrowed cash was recorded as restricted cash. The issuance of the Notes and the increase in restricted cash both in the amount of $1,228 were not reflected in the accompanying Statement of Consolidated Cash Flows as these represent noncash financing and investing activities, respectively. The subsequent release of the $1,228 from escrow occurred on October 31, 2016 in preparation for the Separation Transaction. This decrease in restricted cash was reflected in the accompanying Statement of Consolidated Cash Flows as a cash inflow in the Net change in restricted cash line item. BNDES Loans—Prior to July 5, 2016, Alcoa Alumínio (Alumínio), an indirect wholly-owned subsidiary of Alcoa Corporation, had a loan agreement with Brazil’s National Bank for Economic and Social Development (BNDES) that provided for a financing commitment of $397 (R$687), which was divided into three subloans and was used to pay for certain expenditures of the Estreito hydroelectric power project. On July 5, 2016, this loan agreement was amended to change the borrower from Alumínio to a wholly-owned subsidiary of Alumínio. Interest on the three subloans is a Brazil real rate of interest equal to BNDES’ long-term interest rate, 7.50% and 7.00% as of December 31, 2016 and 2015, respectively, plus a weighted-average margin of 2.67% and 1.48%, respectively. Principal and interest are payable monthly, which began in October 2011 and end in September 2029 for two of the subloans totaling R$667 and began in July 2012 and end in June 2018 for the subloan of R$20. This loan may be repaid early without penalty with the approval of BNDES. As of December 31, 2016 and 2015, outstanding borrowings were $150 (R$490) and $136 (R$522), respectively, and the weighted-average interest rate was 10.22% and 8.49%, respectively. During 2016 and 2015, Alumínio’s subsidiary and/or Alumínio repaid $14 (R$48) and $15 (R$48), respectively, of outstanding borrowings. Additionally, Alumínio borrowed less than $1 (R$1) under the loan in 2015. Alumínio has a loan agreement with BNDES that provides for a financing commitment of $85 (R$177), which also was used to pay for certain expenditures of the Estreito hydroelectric power project. Interest on the loan is a Brazil real rate of interest equal to BNDES’ long-term interest rate plus a margin of 1.55%. Principal and interest are payable monthly, which began in January 2013 and end in September 2029. This loan may be repaid early without penalty with the approval of BNDES. As of December 31, 2016 and 2015, Alumínio’s outstanding borrowings were $42 (R137) and $38 (R$146), respectively, and the interest rate was 9.05% and 8.55%, respectively. During 2016 and 2015, Alumínio repaid $3 (R$11) and $3 (R$10), respectively, of outstanding borrowings. Credit Facility.On September 16, 2016, Alcoa Corporation and ANHBV entered into a revolving credit agreement with a syndicate of lenders and issuers named therein, as amended, (the “Revolving Credit Agreement”). The Revolving Credit Agreement provides a $1,500 senior secured revolving credit facility (the “Revolving Credit Facility”), the proceeds of which may be used for transaction costs related to the Separation Transaction (see Note A), to provide working capital, and/or for other general corporate purposes of Alcoa Corporation and its subsidiaries. Subject to the terms and conditions of the Revolving Credit Agreement, ANHBV may from time to time request the issuance of letters of credit up to $750 under the Revolving Credit Facility, subject to a sublimit of $400 for any letters of credit issued for the account of Alcoa Corporation or any of its domestic subsidiaries. The Revolving Credit Facility is scheduled to mature on November 1, 2021, unless extended or earlier terminated in accordance with the provisions of the Revolving Credit Agreement. ANHBV may make extension requests during the term of the Revolving Credit Facility, subject to the lender consent requirements set forth in the Revolving Credit Agreement. Under the provisions of the Revolving Credit Agreement, ANHBV will pay a quarterly commitment fee ranging from 0.225% to 0.450% (based on Alcoa Corporation’s leverage ratio) on the unused portion of the Revolving Credit Facility. 137 A maximum of $750 in outstanding borrowings under the Revolving Credit Facility may be denominated in euros. Loans will bear interest at a rate per annum equal to, at ANHBV’s option, either (a) an adjusted LIBOR rate or (b) a base rate determined by reference to the highest of (1) the prime rate of JPMorgan Chase Bank, N.A., (2) the greater of the federal funds effective rate and the overnight bank funding rate, plus 0.5%, and (3) the one month adjusted LIBOR rate plus 1% per annum, plus, in each case, an applicable margin. The applicable margin for all loans will vary based on Alcoa Corporation’s leverage ratio and will range from 1.75% to 2.50% for LIBOR loans and 0.75% to 1.50% for base rate loans. Outstanding borrowings may be prepaid without premium or penalty, subject to customary breakage costs. All obligations of Alcoa Corporation or a domestic entity under the Revolving Credit Facility are secured by, subject to certain exceptions (including a limitation of pledges of equity interests in certain foreign subsidiaries to 65%, and certain thresholds with respect to real property), a first priority lien on substantially all assets of Alcoa Corporation and the material domestic wholly-owned subsidiaries of Alcoa Corporation and certain equity interests of specified non- U.S. subsidiaries. All other obligations under the Revolving Credit Facility are secured by, subject to certain exceptions (including certain thresholds with respect to real property), a first priority security interest in substantially all assets of Alcoa Corporation, ANHBV, the material domestic wholly-owned subsidiaries of Alcoa Corporation, and the material foreign wholly-owned subsidiaries of Alcoa Corporation located in Australia, Brazil, Canada, Luxembourg, the Netherlands, and Norway, including equity interests of certain subsidiaries that directly hold equity interests in AWAC entities. However, no AWAC entity is a guarantor of any obligation under the Revolving Credit Facility and no asset of any AWAC entity, or equity interests in any AWAC entity, will be pledged to secure the obligations under the Revolving Credit Facility. The Revolving Credit Agreement includes a number of customary affirmative covenants. Additionally, the Revolving Credit Agreement contains a number of negative covenants (applicable to Alcoa Corporation and certain subsidiaries described as restricted), that, subject to certain exceptions, include limitations on (among other things): liens; fundamental changes; sales of assets; indebtedness; entering into restrictive agreements; restricted payments, including shareholder dividends and repurchases of common stock (see below); investments, loans, advances, guarantees, and acquisitions; transactions with affiliates; amendment of certain material documents; and a covenant prohibiting reductions in the ownership of AWAC entities, and certain other specified restricted subsidiaries of Alcoa Corporation, below an agreed level. The Revolving Credit Agreement also includes financial covenants requiring the maintenance of a specified interest expense coverage ratio of not less than 5.00 to 1.00, and a leverage ratio for any period of four consecutive fiscal quarters that is not greater than 2.25 to 1.00. As of December 31, 2016, Alcoa Corporation was in compliance with all such covenants. In reference to the restricted payments covenant mentioned above, Alcoa Corporation may declare and make annual ordinary dividends in an aggregate amount not to exceed $38 in each of the November 1, 2016 through December 31, 2017 time period and annual 2018, $50 in each of annual 2019 and 2020, and $75 in the January 1, 2021 through November 1, 2021 time period (see below), except that 50% of any unused amount of the base amount in any of the specified time periods may be used in the next succeeding period following the use of the base amount in said time period. Also, Alcoa Corporation may repurchase shares of its common stock pursuant to stock option exercises and benefit plans in an aggregate amount not to exceed $25 during any fiscal year, except that 50% of any unused amount of the base amount in any fiscal year may be used in the next succeeding fiscal year following the use of the base amount in said fiscal year. The Revolving Credit Agreement contains customary events of default, including with respect to a failure to make payments under the Revolving Credit Facility, cross-default and cross-judgment default, and certain bankruptcy and insolvency events. There were no amounts outstanding at December 31, 2016 and no amounts were borrowed during 2016 (September 16th through December 31st) under the Revolving Credit Facility. 138 M. Preferred and Common Stock Preferred Stock.Alcoa Corporation is authorized to issue 100,000,000 shares of preferred stock at a par value of $0.01 per share. At December 31, 2016, Alcoa Corporation had no issued preferred stock. Common Stock.Alcoa Corporation is authorized to issue 750,000,000 shares of common stock at a par value of $0.01 per share. On November 1, 2016, in conjunction with the Separation Transaction (see Note A), Alcoa Corporation distributed 182,471,195 shares of its common stock. Of this amount, 146,159,428 shares were distributed to ParentCo’s shareholders and 36,311,767 shares were retained by ParentCo (on February 14, 2017, Arconic sold 23,353,000 of these shares). From November 1, 2016 through December 31, 2016, Alcoa Corporation issued 459,800 shares for employee stock-based compensation plans. As of December 31, 2016, Alcoa Corporation had 182,930,995 issued and outstanding shares of common stock. Dividends on common stock are subject to authorization by Alcoa Corporation’s Board of Directors. Alcoa Corporation did not declare any dividends from November 1, 2016 through December 31, 2016. As of December 31, 2016, 18,540,200 shares of common stock were available for issuance under Alcoa Corporation’s employee stock-based compensation plan. Alcoa Corporation issues new shares to satisfy the exercise of stock options and the conversion of stock awards. Stock-based Compensation For all periods prior to the Separation Date (see Note A), Alcoa Corporation’s employees participated in ParentCo’s stock-based compensation plan. The stock-based compensation expense recorded by Alcoa Corporation in the referenced periods includes expense associated with employees historically attributable to Alcoa Corporation’s operations and an allocation of expense (see Note A) related to ParentCo’s corporate employees. For the last two months of 2016, Alcoa Corporation employees participated in the Company’s stock-based compensation plan. Effective November 1, 2016, all outstanding stock options (vested and non-vested) and non-vested stock awards originally granted under ParentCo’s stock-based compensation plan related to Alcoa Corporation employees were replaced with similar stock options and stock awards under Alcoa Corporation’s stock-based compensation plan. In order to preserve the intrinsic value of the stock options and stock awards originally granted under ParentCo’s stock- based compensation plan, the number of stock options and stock awards issued under Alcoa Corporation’s stock-based compensation plan were increased by a ratio of 1.34 developed by dividing the October 31, 2016 closing market price of ParentCo’s common stock ($28.72) by the October 31, 2016 closing market price of Alcoa Corporation’s “when issued” common stock ($21.44). This resulted in a beginning balance of outstanding stock options and stock awards under Alcoa Corporation’s stock-based compensation plan of 4,673,829 and 2,605,423, respectively, as of November 1, 2016. The following description of Alcoa Corporation’s stock-based compensation plan is not materially different from the description of ParentCo’s stock-based compensation plan prior to the Separation Transaction (see Note A). Alcoa Corporation has a stock-based compensation plan under which stock options and stock awards generally will be granted in February each year to eligible employees (Alcoa Corporation’s Board of Directors also receive certain stock awards; however, these amounts are not material). Most plan participants can choose whether to receive their award in the form of stock options, stock awards, or a combination of both. This choice is made before the grant is issued and is irrevocable. Stock options will be granted at the closing market price of Alcoa Corporation’s common stock on the date of grant and will vest over a three-year service period (1/3 each year) with a ten-year contractual term. Stock awards will vest over a three-year service period from the date of grant and certain of these awards also include performance conditions. In 2016, 2015, and 2014, the final number of performance stock awards earned will be based on Alcoa Corporation’s achievement of sales and profitability targets over the respective three-year period. One-third of the award will be earned each year based on the performance against the pre-established targets for that year. The performance stock awards earned over the three-year period vest at the end of the third year. 139 In 2016, 2015, and 2014, Alcoa Corporation recognized stock-based compensation expense of $28, $35, and $39, respectively, of which approximately 80% related to stock awards in each period (there was no stock-based compensation expense capitalized in 2016, 2015, or 2014). Of the total pretax stock-based compensation expense recognized in 2016, 2015, and 2014, $16, $21, and $21, respectively, relates to the allocation of expense for ParentCo’s corporate employees. As part of ParentCo’s stock-based compensation plan design, individuals who are retirement- eligible have a six-month requisite service period in the year of grant. As a result, a larger portion of expense was recognized in the first half of each year for these retirement-eligible employees. Of the total pretax stock-based compensation expense recognized in 2016, 2015, and 2014, $7, $6, and $8, respectively, pertains to the acceleration of expense related to retirement-eligible employees. Stock-based compensation expense is based on the grant date fair value of the applicable equity grant. For stock awards, the fair value was equivalent to the closing market price of either ParentCo’s or Alcoa Corporation’s common stock on the date of grant. For stock options, the fair value was estimated on the date of grant using a lattice-pricing model, which generated a result of $2.12, $4.47, and $2.84 per option in 2016, 2015, and 2014, respectively. The lattice-pricing model uses a number of assumptions to estimate the fair value of a stock option, including an average risk-free interest rate, dividend yield, volatility, annual forfeiture rate, exercise behavior, and contractual life. The following paragraph describes in detail the assumptions used by ParentCo (Alcoa Corporation did not grant any stock options from November 1, 2016 through December 31, 2016) to estimate the fair value of stock options granted in 2016 (the assumptions used to estimate the fair value of stock options granted in 2015 and 2014 were not materially different). The risk-free interest rate (2.06%) was based on a yield curve of interest rates at the time of the grant based on the contractual life of the option. The dividend yield (1.1%) was based on a one-year average. Volatility (44.5%) was based on historical and implied volatilities over the term of the option. ParentCo utilized historical option forfeiture data to estimate annual pre- and post-vesting forfeitures (7%). Exercise behavior (60%) was based on a weighted average exercise ratio (exercise patterns for grants issued over the number of years in the contractual option term) of an option’s intrinsic value resulting from historical employee exercise behavior. Based upon the other assumptions used in the determination of the fair value, the life of an option (5.7 years) was an output of the lattice-pricing model. For stock options outstanding as of October 31, 2016 that were originally granted under ParentCo’s stock-based compensation plan to Alcoa Corporation employees, the previously-mentioned fair values were adjusted to reflect both the impact of ParentCo’s 1-for-3 reverse stock split that occurred on October 5, 2016 and to maintain the intrinsic value of the stock options as a result of the Separation Transaction (see Note A). As a result, the fair value of the stock options originally granted in 2016, 2015, and 2014 was adjusted to $4.75, $10.01, and $6.36, respectively. Alcoa Corporation did not recognize any incremental stock-based compensation expense as a result of this adjustment. The activity for stock options and stock awards during the November 1, 2016 through December 31, 2016 timeframe was as follows: Stock options Stock awards Number of options Weighted average exercise price Number of awards Weighted average FMV per award Outstanding, November 1, 2016 4,673,829 $24.42 2,605,423 $22.59 Granted - - 22,858 28.88 Exercised (458,925) 21.69 - - Converted - - (1,265) 22.31 Expired or forfeited (106,369) 25.73 (45,011) 22.75 Performance share adjustment - - (24,163) 21.88 Outstanding, December 31, 2016 4,108,535 24.69 2,557,842 22.65 140 As of December 31, 2016, the number of stock options outstanding had a weighted average remaining contractual life of 5.74 years and a total intrinsic value of $21. Additionally, 2,786,416 of the stock options outstanding were fully vested and exercisable and had a weighted average remaining contractual life of 4.44 years, a weighted average exercise price of $26.92, and a total intrinsic value of $9 as of December 31, 2016. In 2016, cash received from stock option exercises was $10 and the total intrinsic value of stock options exercised during 2016 was $4. At December 31, 2016, there was $17 (pretax) of unrecognized compensation expense related to non-vested stock option grants and non-vested stock award grants. This expense is expected to be recognized over a weighted average period of 1.5 years. N. Pension and Other Postretirement Benefits Alcoa maintains pension plans covering most U.S. employees and certain employees in foreign locations. Pension benefits generally depend on length of service, job grade, and remuneration. Substantially all benefits are paid through pension trusts that are sufficiently funded to ensure that all plans can pay benefits to retirees as they become due. Most salaried and non-bargaining hourly U.S. employees hired after March 1, 2006 participate in a defined contribution plan instead of a defined benefit plan. ParentCo also maintains health care and life insurance postretirement benefit plans covering eligible U.S. retired employees and certain retirees from foreign locations. Generally, the medical plans are unfunded and pay a percentage of medical expenses, reduced by deductibles and other coverage. Life benefits are generally provided by insurance contracts. ParentCo retains the right, subject to existing agreements, to change or eliminate these benefits. All salaried and certain non-bargaining hourly U.S. employees hired after January 1, 2002 and certain bargaining hourly U.S. employees hired after July 1, 2010 are not eligible for postretirement health care benefits. All salaried and certain hourly U.S. employees that retire on or after April 1, 2008 are not eligible for postretirement life insurance benefits. For all periods prior to August 1, 2016 (see below), eligible employees attributable to Alcoa Corporation operations participated in the U.S. defined benefit pension and other postretirement benefit plans sponsored by ParentCo (the “Shared Plans”), which included Arconic and ParentCo corporate participants. Alcoa Corporation accounted for the Shared Plans as multiemployer benefit plans. Accordingly, Alcoa Corporation did not record an asset or liability to recognize the funded status of the Shared Plans. The multiemployer contribution expense attributable to employees of Alcoa Corporation-related operations was based primarily on pensionable compensation of such employees for the pension plans and estimated interest costs for the other postretirement benefit plans. Multiemployer contribution expenses attributable to Alcoa Corporation for the Shared Plans were $28, $64, and $64 related to pension plans and $12, $32, and $39 related to other postretirement benefit plans in 2016 (through July 31, 2016), 2015, and 2014, respectively. Additionally, for all periods prior to August 1, 2016, Alcoa Corporation recorded an allocation of expenses for the Shared Plans attributable to ParentCo corporate participants as well as to closed and sold operations (see Cost Allocations in Note A). Including the multiemployer expenses described above, the total expenses associated with the Shared Plans reflected in the accompanying Consolidated Statement of Operations were $73, $191, and $183 in 2016 (through July 31, 2016), 2015, and 2014, respectively. Furthermore, certain of the ParentCo plans described above were specific to employees attributable to Alcoa Corporation operations (non-U.S.) in their entirety (the “Direct Plans”). Alcoa Corporation accounted for the Direct Plans as defined benefit pension and other postretirement benefit plans. Accordingly, the funded status of each of the Direct Plans is recorded in the accompanying Consolidated Balance Sheet. Actuarial gains and losses that have not yet been recognized in earnings are recorded in Accumulated other comprehensive loss until they are amortized as a component of net periodic benefit cost. The determination of benefit obligations and recognition of expenses related to Direct Plans are dependent on various assumptions. The major assumptions primarily relate to discount rates, long- term expected rates of return on plan assets, and future compensation increases. Management develops each assumption using relevant company experience in conjunction with market-related data for each of the plans. 141 In preparation for the Separation Transaction (see Note A), effective August 1, 2016, certain of the Shared Plans were separated into standalone plans for both Alcoa Corporation (the “New Direct Plans”) and Arconic. Accordingly, the New Direct Plans for Alcoa Corporation were measured as of August 1, 2016. One of the primary assumptions used to measure the New Direct Plans was a weighted average discount rate of 3.48%. This measurement yielded a combined net unfunded status of $2,348, which was recognized in Alcoa Corporation’s Consolidated Balance Sheet at that time, consisting of a current liability of $131 and a noncurrent liability of $2,217. Additionally, Alcoa Corporation recognized $2,498 in Accumulated other comprehensive loss. Additionally, certain other Shared Plans were assumed by Alcoa Corporation (the “Additional New Direct Plans”) that did not require to be separated and/or to be remeasured. The Additional New Direct Plans had a combined net unfunded status of $180, which was recognized in Alcoa Corporation’s Consolidated Balance Sheet, consisting of a current liability of $5 and a noncurrent liability of $175. Additionally, Alcoa Corporation recognized $206 in Accumulated other comprehensive loss. Net periodic benefit cost for the Direct Plans, New Direct Plans, and/or Additional New Direct Plans were $83, $106, and $101 related to pensions plans and $21, $(12), and $2 related to other postretirement benefit plans in the respective periods in 2016, 2015, and 2014, respectively. Including the total expenses associated with the Shared Plans described above, Alcoa Corporation recognized total expenses related to all pension and other postretirement benefits of $177, $285, and $286 in 2016, 2015, and 2014, respectively. The funded status of all of Alcoa Corporation’s Direct Plans, New Direct Plans, and Additional New Direct Plans are measured as of December 31 each calendar year. All of the information that follows for pension and other postretirement benefit plans is applicable to only the Direct Plans, New Direct Plans, and Additional New Direct Plans in the respective periods. 142 Obligations and Funded Status Pension benefits Other postretirement benefits December 31, 2016 2015 2016 2015 Change in benefit obligation Benefit obligation at beginning of year $ 2,246 $2,507 $ 82 $ 98 Benefit obligation assumed on August 1, 2016 5,316 - 1,277 - Service cost 74 63 2 - Interest cost 142 95 16 4 Amendments 1 16 - - Actuarial (gains) losses (244) 27 (33) (7) Settlements (80) (65) - - Curtailments - (13) - (5) Benefits paid, net of participants’ contributions (218) (65) (61) (5) Medicare Part D subsidy receipts - - 3 - Foreign currency translation impact 32 (319) - (3) Benefit obligation at end of year* $ 7,269 $2,246 $ 1,286 $ 82 Change in plan assets Fair value of plan assets at beginning of year $ 1,891 $2,090 $ - $ - Fair value of plan assets assumed on August 1, 2016 4,065 - - - Actual return on plan assets (332) 111 - - Employer contributions 72 76 - - Participant contributions 18 19 - - Benefits paid (224) (76) - - Administrative expenses (11) (6) - - Settlements (80) (65) - - Foreign currency translation impact 22 (258) - - Fair value of plan assets at end of year* $ 5,421 $1,891 $ - $ - Funded status*$(1,848) $ (355) $(1,286) $(82) Less: Amounts attributed to joint venture partners (30) (30) - - Net funded status $(1,818) $ (325) $(1,286) $(82) Amounts recognized in the Consolidated Balance Sheet consist of: Noncurrent assets $ 43 $ 35 $ - $ - Current liabilities (10) (1) (120) (4) Noncurrent liabilities (1,851) (359) (1,166) (78) Net amount recognized $(1,818) $ (325) $(1,286) $(82) Amounts recognized in Accumulated Other Comprehensive Loss consist of: Net actuarial loss $ 3,254 $ 625 $ 295 $ 1 Prior service cost (benefit) 42 35 (36) - Total, before tax effect 3,296 660 259 1 Less: Amounts attributed to joint venture partners 36 39 - - Net amount recognized, before tax effect $ 3,260 $ 621 $ 259 $ 1 Other Changes in Plan Assets and Benefit Obligations Recognized in Other Comprehensive Loss consist of: Net actuarial loss (benefit) $ 337 $ (61) $ (33) $(12) Amortization of accumulated net actuarial loss (105) (45) (8) 7 Prior service cost (benefit) 2 (17) (1) 1 Amortization of prior service (cost) benefit (7) (6) 5 9 Total, before tax effect 227 (129) (37) 5 Less: Amounts attributed to joint venture partners (3) (5) - - Net amount recognized, before tax effect $ 230 $ (124) $ (37) $ 5 143 * At December 31, 2016, the benefit obligation, fair value of plan assets, and funded status for U.S. pension plans were $4,977, $3,504, and $(1,473), respectively. At December 31, 2015, the benefit obligation, fair value of plan assets, and funded status were related only to non-U.S. pension plans. Pension Plan Benefit Obligations Pension benefits 2016 2015 The projected benefit obligation and accumulated benefit obligation for all defined benefit pension plans was as follows: Projected benefit obligation $7,269 $2,246 Accumulated benefit obligation 7,075 2,049 The aggregate projected benefit obligation and fair value of plan assets for pension plans with projected benefit obligations in excess of plan assets was as follows: Projected benefit obligation 6,699 2,175 Fair value of plan assets 4,807 1,789 The aggregate accumulated benefit obligation and fair value of plan assets for pension plans with accumulated benefit obligations in excess of plan assets was as follows: Accumulated benefit obligation 6,531 1,467 Fair value of plan assets 4,807 1,252 Components of Net Periodic Benefit Cost Pension benefits(1)Other postretirement benefits(2) 2016 2015 2014 2016 2015 2014 Service cost $ 61 $ 51 $ 55 $ 2 $ - $ 1 Interest cost 138 89 114 16 4 5 Expected return on plan assets (242) (121) (134) - - - Recognized net actuarial loss 102 42 34 8 (3) (2) Amortization of prior service cost (benefit) 7 6 8 (5) (9) (2) Settlements(3)16 14 24 - - - Curtailments(4)- 9 - - (4) - Special termination benefits (5)116 - - - - Net periodic benefit cost(6)$ 83 $ 106 $ 101 $21 $(12) $ 2 (1)In 2016, net periodic benefit cost for U.S pension plans was $21.

The cash flows of the plans’ projected benefit obligations are discounted using a single equivalent rate derived from yields on high quality corporate bonds, which represent a broad diversification of issuers in various sectors. The yield curve model parallels the plans’ projected cash flows, which have an average duration ranging from 11 to 15 years, and the underlying cash flows of the bonds included in the model exceed the cash flows needed to satisfy the Company’s plans’ obligations multiple times. If a deep market of high quality corporate bonds does not exist in a country, then the yield on government bonds plus a corporate bond yield spread is used. The rate of compensation increase is based upon anticipated compensation increases and estimated inflation. For 2017, the rate of compensation increase will be 3.5%. Weighted average assumptions used to determine net periodic benefit cost for pension and other postretirement benefit plans were as follows: 2016 2015 2014 Discount rate—pension plans* 3.45% 4.09% 5.14% Discount rate—other postretirement benefit plans* 2.90 4.15 4.88 Expected long-term rate of return on plan assets—pension plans 7.31 6.91 6.91 Rate of compensation increase—pension plans 3.65 3.74 3.79 * In all periods presented, the respective discount rates were used to determine net periodic benefit cost for most plans for the full annual period. However, the discount rates for a limited number of plans were updated during 2016, 2015, and 2014 to reflect the remeasurement of these plans due to settlements and/or curtailments. The updated discount rates used were not significantly different from the discount rates presented. The expected long-term rate of return on plan assets is generally applied to a five-year market-related value of plan assets (a four-year average or the fair value at the plan measurement date is used for certain non-U.S. plans). The process used by management to develop this assumption is one that relies on forward-looking investment returns by asset class. Management incorporates expected future investment returns on current and planned asset allocations using information from various external investment managers and consultants, as well as management’s own judgment. For 2016, 2015, and 2014, the expected long-term rate of return used by management was based on the prevailing and planned strategic asset allocations, as well as estimates of future returns by asset class. For 2017, management anticipates that 7.47% will be the weighted-average expected long-term rate of return. Assumed health care cost trend rates for U.S. other postretirement benefit plans were as follows (non-U.S. plans are not material): 2016 2015 2014 Health care cost trend rate assumed for next year 5.5% 5.5% 5.5% Rate to which the cost trend rate gradually declines 4.5% 4.5% 4.5% Year that the rate reaches the rate at which it is assumed to remain 2020 2019 2018 145 The assumed health care cost trend rate is used to measure the expected cost of gross eligible charges covered by Alcoa Corporation’s other postretirement benefit plans. For 2017, a 5.5% trend rate will be used, reflecting management’s best estimate of the change in future health care costs covered by the plans. The plans’ actual annual health care cost trend experience (based on ParentCo’s plans that previously included the Alcoa Corporation participants) over the past three years has ranged from 3.6%. to 9.6% Management does not believe this three-year range is indicative of expected increases for future health care costs over the long-term. Assumed health care cost trend rates have an effect on the amounts reported for a health care plan. A one-percentage point change in these assumed rates would have the following effects: 1% increase 1% decrease Effect on other postretirement benefit obligations $80 $(72) Effect on total of service and interest cost components 1 (1) Plan Assets Alcoa Corporation’s pension plan investment policy and weighted average asset allocations at December 31, 2016 and 2015, by asset class, were as follows: Plan assets at December 31, Asset class Policy range 2016 2015 Equities 20–55% 37% 40% Fixed income 25–55% 36 37 Other investments 15–35% 27 23 Total 100% 100% The principal objectives underlying the investment of the pension plans’ assets are to ensure that Alcoa Corporation can properly fund benefit obligations as they become due under a broad range of potential economic and financial scenarios, maximize the long-term investment return with an acceptable level of risk based on such obligations, and broadly diversify investments across and within various asset classes to protect asset values against adverse movements. Specific objectives for long-term investment strategy include reducing the volatility of pension assets relative to pension liabilities and achieving risk factor diversification across the balance of the asset portfolio. A portion of the assets are matched to the interest rate profile of the benefit obligation through long duration fixed income investments and fixed income derivative instruments. Exposure to broad equity risk has been decreased and diversified through investments in discretionary and systematic macro hedge funds, long/short equity hedge funds, and global and emerging market equities. Investments are further diversified by strategy, asset class, geography, and sector to enhance returns and mitigate downside risk. A large number of external investment managers are used to gain broad exposure to the financial markets and to mitigate manager-concentration risk. Investment practices comply with the requirements of applicable laws and regulations in the respective jurisdictions, including the Employee Retirement Income Security Act of 1974 (ERISA) in the United States. The use of derivative instruments by external investment managers is permitted where appropriate and necessary for achieving overall investment policy objectives and for mitigating interest rate and other asset class risks. The following section describes the valuation methodologies used by the trustees to measure the fair value of pension plan assets, including, if applicable, an indication of the level in the fair value hierarchy in which each type of asset is generally classified (see Note O for the definition of fair value and a description of the fair value hierarchy). On January 1, 2016, Alcoa Corporation adopted changes issued by the FASB related to certain investments for which fair 146 value is measured at net asset value as a practical expedient (see Recently Adopted Accounting Guidance in Note B). The changes remove the requirement to categorize within the fair value hierarchy all such investments. Additionally, an entity is required to remove these investments from the fair value hierarchy in all prior periods presented. As such, the information in the table below has been updated to conform to these changes. All references below to net asset value means net asset value of shares (or its equivalent) held at December 31 as a practical expedient. Equities.These securities consist of: (i) direct investments in the stock of publicly traded U.S. and non-U.S. companies and are valued based on the closing price reported in an active market on which the individual securities are traded (generally classified in Level 1); (ii) the plans’ share of commingled funds that are invested in the stock of publicly traded companies and are valued at net asset value; and (iii) direct investments in long/short equity hedge funds and private equity (limited partnerships and venture capital partnerships) and are valued at net asset value. Fixed income.These securities consist of: (i) U.S. government debt and are generally valued using quoted prices (included in Level 1); (ii) cash and cash equivalents invested in publicly-traded funds and are valued based on the closing price reported in an active market on which the individual securities are traded (generally classified in Level 1); (iii) publicly traded U.S. and non-U.S. fixed interest obligations (principally corporate bonds and debentures) and are valued through consultation and evaluation with brokers in the institutional market using quoted prices and other observable market data (included in Level 2); (iv) fixed income derivatives and are generally valued using industry standard models with market-based observable inputs (included in Level 2); and (v) cash and cash equivalents invested in institutional funds and are valued at net asset value. Other investments.These investments include, among others: (i) exchange traded funds, such as real estate investment trusts and gold, and are valued based on the closing price reported in an active market on which the investments are traded (included in Level 1); (ii) the plans’ share of commingled funds that are invested in real estate investment trusts and are valued at net asset value; (iii) direct investments of discretionary and systematic macro hedge funds and private real estate (includes limited partnerships) and are valued at net asset value; and (iv) absolute return hedge funds and are valued at net asset value. The fair value methods described above may not be indicative of net realizable value or reflective of future fair values. Additionally, while Alcoa Corporation believes the valuation methods used by the plans’ trustees are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. 147 The following table presents the fair value of pension plan assets classified under either the appropriate level of the fair value hierarchy or net asset value: December 31, 2016 Level 1 Level 2 Level 3 Net Asset Value Total Equities: Equity securities $ 520 $ - $- $ 772 $1,292 Long/short equity hedge funds - - - 449 449 Private equity - - - 246 246 $ 520 $ - $- $1,467 $1,987 Fixed income: Intermediate and long duration government/credit $ 78 $283 $- $ 167 $ 528 Cash and cash equivalent funds 897 - - 468 1,365 Other - 61 - - 61 $ 975 $344 $- $ 635 $1,954 Other investments: Real estate $ 88 $ - $- $ 331 $ 419 Discretionary and systematic macro hedge funds - - - 866 866 Other 71 - - 139 210 $ 159 $ - $- $1,336 $1,495 Total* $1,654 $344 $- $3,438 $5,436 December 31, 2015 Level 1 Level 2 Level 3 Net Asset Value Total Equities: Equity securities $ 160 $ - $- $ 480 $ 640 Long/short equity hedge funds - - - 26 26 Private equity - - - 101 101 $ 160 $ - $- $ 607 $ 767 Fixed income: Intermediate and long duration government/credit $ 152 $226 $- $ 157 $ 535 Other - 24 - 139 163 $ 152 $250 $- $ 296 $ 698 Other investments: Real estate $ 4 $ - $- $ 185 $ 189 Discretionary and systematic macro hedge funds - - - 46 46 Other 4 - - 187 191 $ 8 $ - $- $ 418 $ 426 Total $ 320 $250 $- $1,321 $1,891 * As of December 31, 2016, the total fair value of pension plan assets excludes a net payable of $15, which represents the amount due to Arconic pension plans from Alcoa Corporation pension plans as a result of certain plans that were separated between the two companies. Funding and Cash Flows It is Alcoa Corporation’s policy to fund amounts for pension plans sufficient to meet the minimum requirements set forth in applicable country benefits laws and tax laws, including the Pension Protection Act of 2006; the Worker, Retiree, and Employer Recovery Act of 2008; the Moving Ahead for Progress in the 21 st Century Act of 2012; the Highway and Transportation Funding Act of 2015; and the Bipartisan Budget Act of 2016 for U.S. plans. From time to 148 time, Alcoa Corporation contributes additional amounts as deemed appropriate. In 2016 and 2015, cash contributions to Alcoa Corporation’s pension plans were $66 and $69. The minimum required contribution to pension plans in 2017 is estimated to be $115, of which $60 is for U.S. plans. Benefit payments expected to be paid to pension and other postretirement benefit plan participants and expected Medicare Part D subsidy receipts are as follows: Year ended December 31, Pension benefits Gross Other postretirement benefits Medicare Part D subsidy receipts Net Other postretirement benefits 2017 $ 475 $ 130 $10 $120 2018 475 120 10 110 2019 475 115 10 105 2020 480 115 10 105 2021 480 115 10 105 2022 through 2026 2,375 495 45 450 $4,760 $1,090 $95 $995 Defined Contribution Plans Alcoa Corporation sponsors savings and investment plans in several countries, including the United States and Australia. Prior to the Separation Date (see Note A), employees attributable to Alcoa Corporation operations participated in ParentCo-sponsored plans. Alcoa Corporation’s expenses related to all such plans were $57 in 2016, $59 in 2015, and $68 in 2014. In the United States, employees may contribute a portion of their compensation to the plans, and Alcoa Corporation (ParentCo prior to Separation Date) matches a portion of these contributions in equivalent form of the investments elected by the employee. O. Derivatives and Other Financial Instruments Fair Value.Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy distinguishes between (i) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (ii) an entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below: • Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. • Level 2—Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means. • Level 3—Inputs that are both significant to the fair value measurement and unobservable. Derivatives.Alcoa Corporation is exposed to certain risks relating to its ongoing business operations, including financial, market, political, and economic risks. The following discussion provides information regarding Alcoa Corporation’s exposure to the risks of changing commodity prices, interest rates, and foreign currency exchange rates. 149 Alcoa Corporation’s commodity and derivative activities are subject to the management, direction, and control of the Strategic Risk Management Committee (SRMC), which is composed of the chief executive officer, the chief financial officer, and other officers and employees that the chief executive officer selects. The SRMC meets on a periodic basis to review derivative positions and strategy and reports to Alcoa Corporation’s Board of Directors on the scope of its activities. The aluminum, energy, interest rate, and foreign exchange contracts are held for purposes other than trading. They are used primarily to mitigate uncertainty and volatility, and to cover underlying exposures. Alcoa Corporation is not involved in trading activities for energy, weather derivatives, or other nonexchange commodity trading activities. A number of Alcoa Corporation’s aluminum, energy, and foreign exchange contracts are classified as Level 1 or Level 2 under the fair value hierarchy. These aluminum, energy, and foreign exchange contracts are not material to Alcoa Corporation’s Consolidated Financial Statements for all periods presented. In addition to the Level 1 and 2 derivative instruments described above, Alcoa Corporation has nine (ten prior to October 2016) derivative instruments classified as Level 3 under the fair value hierarchy. These instruments are composed of seven (eight prior to October 2016) embedded aluminum derivatives, an energy contract, and an embedded credit derivative, all of which relate to energy supply contracts associated with nine smelters and three refineries. Five of the embedded aluminum derivatives and the energy contract (through November 2016 – see below) were designated as cash flow hedging instruments and two (three prior to October 2016) of the embedded aluminum derivatives, the embedded credit derivative, and the energy contract (in December 2016 – see below) were not designated as hedging instruments. The following section describes the valuation methodologies used by Alcoa Corporation to measure its Level 3 derivative instruments at fair value. Derivative instruments classified as Level 3 in the fair value hierarchy represent those in which management has used at least one significant unobservable input in the valuation model. Alcoa Corporation uses a discounted cash flow model to fair value all Level 3 derivative instruments. Where appropriate, the description below includes the key inputs to those models and any significant assumptions. These valuation models are reviewed and tested at least on an annual basis. Inputs in the valuation models for Level 3 derivative instruments are composed of the following: (i) quoted market prices (e.g., aluminum prices on the 10-year London Metal Exchange (LME) forward curve and energy prices), (ii) significant other observable inputs (e.g., information concerning time premiums and volatilities for certain option type embedded derivatives and regional premiums for aluminum contracts), and (iii) unobservable inputs (e.g., aluminum and energy prices beyond those quoted in the market). For periods beyond the term of quoted market prices for aluminum, Alcoa Corporation estimates the price of aluminum by extrapolating the 10-year LME forward curve. Additionally, for periods beyond the term of quoted market prices for energy, management has developed a forward curve based on independent consultant market research. Where appropriate, valuations are adjusted for various factors such as liquidity, bid/offer spreads, and credit considerations. Such adjustments are generally based on available market evidence (Level 2). In the absence of such evidence, management’s best estimate is used (Level 3). If a significant input that is unobservable in one period becomes observable in a subsequent period, the related asset or liability would be transferred to the appropriate classification (Level 1 or 2) in the period of such change (there were no such transfers in the periods presented). Alcoa Corporation has two power contracts, each of which contain an embedded derivative that indexes the price of power to the LME price of aluminum. Additionally, Alcoa Corporation has three power contracts, each of which contain an embedded derivative that indexes the price of power to the LME price of aluminum plus the Midwest premium. The embedded derivatives in these five power contracts are primarily valued using observable market prices; however, due to the length of the contracts, the valuation models also require management to estimate the long-term price of aluminum based upon an extrapolation of the 10-year LME forward curve. Additionally, for three of the contracts, management also estimates the Midwest premium, generally, for the next twelve months based on recent transactions and then holds the premium estimated in that twelfth month constant for the remaining duration of the 150 contract. Significant increases or decreases in the actual LME price beyond 10 years would result in a higher or lower fair value measurement. An increase in actual LME price and/or the Midwest premium over the inputs used in the valuation models will result in a higher cost of power and a corresponding decrease to the derivative asset or increase to the derivative liability. The embedded derivatives have been designated as cash flow hedges of forward sales of aluminum. Unrealized gains and losses were included in Other comprehensive loss on the accompanying Consolidated Balance Sheet while realized gains and losses were included in Sales on the accompanying Statement of Consolidated Operations. Also, Alcoa Corporation had a power contract (expired in September 2016 – see below) separate from above that contains an LME-linked embedded derivative. Prior to its expiration, the embedded derivative was valued using the probability and interrelationship of future LME prices, Australian dollar to U.S. dollar exchange rates, and the U.S. consumer price index. Significant increases or decreases in the LME price would result in a higher or lower fair value measurement. An increase in actual LME price over the inputs used in the valuation model will result in a higher cost of power and a corresponding decrease to the derivative asset. This embedded derivative did not qualify for hedge accounting treatment. Unrealized gains and losses from the embedded derivative were included in Other expenses (income), net on the accompanying Statement of Consolidated Operations while realized gains and losses were included in Cost of goods sold on the accompanying Statement of Consolidated Operations as electricity purchases were made under the contract. At the time this derivative asset was recognized, an equivalent amount was recognized as a deferred credit in Other noncurrent liabilities and deferred credits on the accompanying Consolidated Balance Sheet (see Note S). This deferred credit was recognized in Other expenses (income), net on the accompanying Statement of Consolidated Operations as power was received over the life of the contract. Additionally, Alcoa Corporation has a natural gas supply contract, which has an LME-linked ceiling. This embedded derivative is valued using probabilities of future LME aluminum prices and the price of Brent crude oil (priced on Platts), including the interrelationships between the two commodities subject to the ceiling. Any change in the interrelationship would result in a higher or lower fair value measurement. An LME ceiling was embedded into the contract price to protect against an increase in the price of oil without a corresponding increase in the price of LME. An increase in oil prices with no similar increase in the LME price would limit the increase of the price paid for natural gas. This embedded derivative did not qualify for hedge accounting treatment. Unrealized gains and losses from the embedded derivative were included in Other expenses (income), net on the accompanying Statement of Consolidated Operations while realized gains and losses were included in Cost of goods sold on the accompanying Statement of Consolidated Operations as gas purchases were made under the contract. In mid-2016, Alcoa Corporation and the related counterparty elected to modify the pricing of an existing power contract for a smelter in the United States. This amendment contains an embedded derivative that indexes the price of power to the LME price of aluminum plus the Midwest premium. The embedded derivative is valued using the interrelationship of future metal prices (LME base plus Midwest premium) and the amount of megawatt hours of energy needed to produce the forecasted metric tons of aluminum at the smelter. Significant increases or decreases in the metal price would result in a higher or lower fair value measurement. An increase in actual metal price over the inputs used in the valuation model will result in a higher cost of power and a corresponding increase to the derivative liability. Management elected not to qualify the embedded derivative for hedge accounting treatment. Unrealized gains and losses from the embedded derivative will be included in Other (income) expenses, net on the accompanying Statement of Consolidated Operations while realized gains and losses will be included in Cost of goods sold on the accompanying Statement of Consolidated Operations as electricity purchases are made under the contract. At the time this derivative liability was recognized, an equivalent amount was recognized as a deferred charge in Other noncurrent assets on the accompanying Consolidated Balance Sheet. This deferred charge will be recognized in Other (income) expenses, net on the accompanying Statement of Consolidated Operations as power is received over the life of the contract. Furthermore, Alcoa Corporation has a power contract, which contains an embedded derivative that indexes the difference between the long-term debt ratings of Alcoa Corporation and the counterparty from any of the three major credit rating agencies. Management uses market prices, historical relationships, and forecast services to determine fair 151 value. Significant increases or decreases in any of these inputs would result in a lower or higher fair value measurement. A wider credit spread between Alcoa Corporation and the counterparty would result in a higher cost of power and a corresponding increase in the derivative liability. This embedded derivative did not qualify for hedge accounting treatment. Unrealized gains and losses were included in Other expenses (income), net on the accompanying Statement of Consolidated Operations while realized gains and losses were included in Cost of goods sold on the accompanying Statement of Consolidated Operations as electricity purchases were made under the contract. Finally, Alcoa Corporation has a derivative contract that hedges the anticipated power requirements at one of its smelters that began when the previous power contract expired in September 2016 (see above). Beyond the term where market information is available, management developed a forward curve, for valuation purposes, based on independent consultant market research. Significant increases or decreases in the power market may result in a higher or lower fair value measurement. Lower prices in the power market would cause a decrease in the derivative asset. The derivative contract had been designated as a cash flow hedge of future purchases of electricity (this designation ceased in December 2016 – see below). Through November 2016, unrealized gains and losses on this contract were recorded in Other comprehensive loss on the accompanying Consolidated Balance Sheet, while realized gains and losses were recorded in Cost of goods sold as electricity purchases were made under the power contract. In August 2016, Alcoa Corporation gave the required notice to terminate this derivative contract one year from the date of notification. As a result, Alcoa Corporation decreased both the related derivative asset recorded in Other noncurrent assets and the unrealized gain recorded in Accumulated other comprehensive loss by $84, which related to the August 2017 through 2036 timeframe, resulting in no impact to Alcoa Corporation’s earnings. In December 2016, a portion of this contract no longer qualified for hedge accounting treatment due to an outage at the smelter, at which point management elected to discontinue hedge accounting for the entire contract. As a result, Alcoa Corporation reclassified an unrealized gain of $7 from Accumulated other comprehensive loss to Other income, net related to the portion of the contract that no longer qualified for hedge accounting. The remaining unrealized gain in Accumulated other comprehensive loss will be reclassified to Other income, net as electricity purchases are made under the power contract through the termination date. 152 The following table presents quantitative information related to the significant unobservable inputs described above for Level 3 derivative contracts: Fair value at December 31, 2016 Unobservable input Range ($ in full amounts) Assets: Embedded aluminum derivatives $497 Price of aluminum beyond forward curve Aluminum: $2,137 per metric ton in 2027 to $2,265 per metric ton in 2029 (two contracts) and $2,563 per metric ton in 2036 (one contract) Midwest premium: $0.835 per pound in 2017 to $0.0900 per pound in 2029 (two contracts) and 2036 (one contract) Embedded aluminum derivative - Interrelationship of future aluminum and oil prices Aluminum: $1,694 per metric ton in 2017 to $1,734 per metric ton in 2018 Oil: $56 per barrel in 2017 to $58 per barrel in 2018 Energy contract 17 Interrelationship of forward energy price and the Consumer Price Index Electricity: $68 per megawatt hour through September 2017 Liabilities: Embedded aluminum derivative 202 Price of aluminum beyond forward curve Aluminum: $2,137 per metric ton in 2027 to $2,157 per metric ton in 2027 Embedded aluminum derivative 28 Interrelationship of LME price to the amount of megawatt hours of energy needed to produce the forecasted metric tons of aluminum Aluminum: $1,694 per metric ton in 2017 to $1,748 per metric ton in 2019 Midwest premium: $0.0835 per pound in 2017 to $0.0900 per pound in 2019 Electricity: rate of 2 million megawatt hours per year Embedded aluminum derivative 2 Interrelationship of LME price to overall energy price Aluminum: $1,711 per metric ton in 2017 to $1,758 per metric ton in 2019 Embedded credit derivative 35 Credit spread between Alcoa Corporation and counterparty 4.12% (Alcoa Corporation— 5.12% and counterparty— 1.00%) 153 The fair values of Level 3 derivative instruments recorded as assets and liabilities in the accompanying Consolidated Balance Sheet were as follows: Asset Derivatives December 31, 2016 December 31, 2015 Derivatives designated as hedging instruments: Prepaid expenses and other current assets: Embedded aluminum derivatives $ 29 $ 72 Other noncurrent assets: Embedded aluminum derivatives 468 994 Energy contract - 2 Total derivatives designated as hedging instruments $497 $1,068 Derivatives not designated as hedging instruments: Prepaid expenses and other current assets: Embedded aluminum derivatives $ - $ 69 Energy contract 17 - Total derivatives not designated as hedging instruments $ 17 $ 69 Total Asset Derivatives $514 $1,137 Liability Derivatives Derivatives designated as hedging instruments: Other current liabilities: Embedded aluminum derivatives $ 17 $ 9 Energy contract - 4 Other noncurrent liabilities and deferred credits: Embedded aluminum derivatives 187 160 Total derivatives designated as hedging instruments $204 $ 173 Derivatives not designated as hedging instruments: Other current liabilities: Embedded aluminum derivative $ 10 $ - Embedded credit derivative 5 6 Other noncurrent liabilities and deferred credits: Embedded aluminum derivative 18 - Embedded credit derivative 30 29 Total derivatives not designated as hedging instruments $ 63 $ 35 Total Liability Derivatives $267 $ 208 The following table shows the net fair values of the Level 3 derivative instruments at December 31, 2016 and the effect on these amounts of a hypothetical change (increase or decrease of 10%) in the market prices or rates that existed as of December 31, 2016: Fair value asset/(liability) Index change of + / -10% Embedded aluminum derivatives $265 $402 Embedded credit derivative (35) 4 Energy contract 17 9 154 The following tables present a reconciliation of activity for Level 3 derivative contracts: Assets Liabilities 2016 Embedded aluminum derivatives Energy contract Embedded aluminum derivatives Embedded credit derivative Energy contract Opening balance—January 1, 2016 $1,135 $ 2 $169 $35 $ 4 Total gains or losses (realized and unrealized) included in: Sales (5) - (12) - - Cost of goods sold (92) - - (5) - Other expenses, net* (13) (80) 2 5 (2) Other comprehensive loss (568) 95 47 - (1) Purchases, sales, issuances, and settlements** - - 32 - - Transfers into and/or out of Level 3** - - - - - Other 40 - (6) - (1) Closing balance—December 31, 2016 $ 497 $ 17 $232 $35 $ - Change in unrealized gains or losses included in earnings for derivative contracts held at December 31, 2016: Sales $ - $ - $ - $ - $ - Cost of goods sold - - - - - Other expenses, net* (13) (80) 2 5 (2) * In August 2016, Alcoa Corporation elected to terminate the energy contract in accordance with the provisions of the agreement (see above). As a result, Alcoa Corporation decreased the derivative asset and recorded a charge in Other income, net of $84, which is reflected in the table above. Additionally, Alcoa Corporation also decreased the related unrealized gain included in Accumulated other comprehensive loss and recorded a benefit in Other income, net of $84. As such, the termination of the specified term of this derivative contract described above did not have an impact on Alcoa Corporation’s earnings. ** In 2016, there was an issuance of a new embedded derivative contained in an amendment to an existing power contract (see above). There were no purchases, sales or settlements of Level 3 derivative instruments. Additionally, there were no transfers of derivative instruments into or out of Level 3. 155 Assets Liabilities 2015 Embedded aluminum derivatives Energy contract Embedded aluminum derivatives Embedded credit derivative Energy contract Opening balance—January 1, 2015 $ 266 $ 2 $ 376 $18 $- Total gains or losses (realized and unrealized) included in: Sales 5 - (16) - - Cost of goods sold (99) - - - - Other expenses, net (8) (2) - 17 1 Other comprehensive loss 964 1 (191) - 3 Purchases, sales, issuances, and settlements* - - - - - Transfers into and/or out of Level 3* - - - - - Foreign currency translation 7 1 - - - Closing balance—December 31, 2015 $1,135 $ 2 $ 169 $35 $4 Change in unrealized gains or losses included in earnings for derivative contracts held at December 31, 2015: Sales $ - $ - $ - $ - $- Cost of goods sold - - - - - Other expenses, net (8) (2) - 17 1 * In 2015, there were no purchases, sales, issuances or settlements of Level 3 derivative instruments.

Derivatives Designated As Hedging Instruments—Cash Flow Hedges For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of unrealized gains or losses on the derivative is reported as a component of other comprehensive income (OCI). Realized gains or losses on the derivative are reclassified from OCI into earnings in the same period or periods during which the hedged transaction impacts earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized directly in earnings immediately. Alcoa Corporation has five Level 3 embedded aluminum derivatives and one Level 3 energy contract (through November 2016 – see above) that have been designated as cash flow hedges as follows. Embedded aluminum derivatives.Alcoa Corporation has entered into energy supply contracts that contain pricing provisions related to the LME aluminum price. The LME-linked pricing features are considered embedded derivatives. Five of these embedded derivatives have been designated as cash flow hedges of forward sales of aluminum, three of which were new derivatives contained in three power contracts that were renewed in late 2014. At December 31, 2016 and 2015, these embedded aluminum derivatives hedge forecasted aluminum sales of 3,127 kmt and 3,307 kmt, respectively. In 2016, 2015, and 2014, Alcoa Corporation recognized an unrealized loss of $615, an unrealized gain of $1,155, and an unrealized gain of $78, respectively, in Other comprehensive loss related to these five derivative instruments. Additionally, Alcoa Corporation reclassified a realized loss of $7, $21, and $28 from Accumulated other comprehensive loss to Sales in 2016, 2015, and 2014, respectively. Assuming market rates remain constant with the rates at December 31, 2016, a realized gain of $8 is expected to be recognized in Sales over the next 12 months. There was no ineffectiveness related to these five derivative instruments in 2016, 2015, and 2014. Energy contract.Alcoa Corporation has a derivative contract that hedges the anticipated power requirements at one of its smelters that became effective when the existing power contract expired in September 2016. In August 2016, Alcoa 156 Corporation elected to terminate most of the remaining term of this derivative contract (see above). Additionally, in December 2016, management elected to discontinue hedge accounting for this contract (see above). This energy contract hedged forecasted electricity purchases of 1,969,544 megawatt hours prior to December 2016 and 59,409,328 megawatt hours at December 31, 2015. In 2016, 2015, and 2014, Alcoa Corporation recognized an unrealized gain of $96, an unrealized loss of $2, and an unrealized loss of $4, respectively, in Other comprehensive loss. Additionally, Alcoa Corporation recognized a gain of $3 and a loss of $3 in Other expenses, net related to hedge ineffectiveness in 2016 and 2015, respectively. There was no ineffectiveness related to this energy contract in 2014. Derivatives Not Designated As Hedging Instruments Alcoa Corporation has two (three prior to October 2016) Level 3 embedded aluminum derivatives and one Level 3 embedded credit derivative that do not qualify for hedge accounting treatment and one Level 3 energy contract that management elected to discontinue hedge accounting treatment (see above). As such, gains and losses related to the changes in fair value of these instruments are recorded directly in earnings. In 2016, 2015, and 2014, Alcoa Corporation recognized a loss of $17, $25, and $13, respectively, in Other expenses (income), net, of which a loss of $15, $8, and $15, respectively, related to the embedded aluminum derivatives, a loss of $5, a loss of $17, and a gain of $2, respectively, related to the embedded credit derivative, and, in 2016, a gain of $3 related to the energy contract. Material Limitations The disclosures with respect to commodity prices, interest rates, and foreign currency exchange risk do not take into account the underlying commitments or anticipated transactions. If the underlying items were included in the analysis, the gains or losses on the futures contracts may be offset. Actual results will be determined by a number of factors that are not under Alcoa Corporation’s control and could vary significantly from those factors disclosed. Alcoa Corporation is exposed to credit loss in the event of nonperformance by counterparties on the above instruments, as well as credit or performance risk with respect to its hedged customers’ commitments. Although nonperformance is possible, Alcoa Corporation does not anticipate nonperformance by any of these parties. Contracts are with creditworthy counterparties and are further supported by cash, treasury bills, or irrevocable letters of credit issued by carefully chosen banks. In addition, various master netting arrangements are in place with counterparties to facilitate settlement of gains and losses on these contracts. Other Financial Instruments.The carrying values and fair values of Alcoa Corporation’s other financial instruments were as follows: December 31, 2016 2015 Carrying value Fair value Carrying value Fair value Cash and cash equivalents $ 853 $ 853 $557 $557 Restricted cash 6 6 - - Long-term debt due within one year 21 21 18 18 Long-term debt, less amount due within one year 1,424 1,573 207 207 The following methods were used to estimate the fair values of other financial instruments: Cash and cash equivalents and Restricted cash.The carrying amounts approximate fair value because of the short maturity of the instruments. The fair value amounts for Cash and cash equivalents and Restricted cash were classified in Level 1. Long-term debt due within one year and Long-term debt, less amount due within one year.The fair value was based on quoted market prices for public debt and on interest rates that are currently available to Alcoa Corporation for issuance of debt with similar terms and maturities for non-public debt. The fair value amounts for all Long-term debt were classified in Level 2 of the fair value hierarchy. 157 P. Income Taxes The components of loss before income taxes were as follows: 2016 2015 2014 United States $(688) $(1,053) $(709) Foreign 526 716 646 $(162) $ (337) $ (63) Provision for income taxes consisted of the following: 2016 2015 2014 Current: Federal*$9$3$1 Foreign 221 313 333 State and local --- 230 316 334 Deferred: Federal*- (85) (5) Foreign (46) 171 (45) State and local --- (46) 86 (50) Total $184 $402 $284 * Includes U.S. taxes related to foreign income A reconciliation of the U.S. federal statutory rate to Alcoa Corporation’s effective tax rate was as follows (the effective tax rate for all periods presented was a provision on a loss): 2016 2015 2014 U.S. federal statutory rate 35.0% 35.0% 35.0% Taxes on foreign operations 24.8 (6.7) (67.5) Nondeductible costs related to the Separation Transaction (9.6) - - Permanent differences on restructuring and other charges and asset disposals - - (19.4) Equity income/loss (3.7) (2.6) (23.0) Noncontrolling interest (1)(7.3) (8.5) (53.5) Statutory tax rate and law changes (2)(0.6) (0.3) (57.0) Tax holidays (3)11.2 6.2 (61.8) Changes in valuation allowances (1.9) (62.6) 3.4 Losses and credits with no tax benefit (4)(163.2) (82.0) (243.0) Impact of capitalization of intercompany debt - 3.3 38.1 Other 1.7 (1.1) (2.1) Effective tax rate (113.6)% (119.3)% (450.8)% (1)In 2014, the noncontrolling interest’s impact on Alcoa Corporation’s effective tax rate was mostly due to the noncontrolling interest’s share of a loss on the divestiture of an ownership interest in a mining and refining joint venture in Jamaica (see Note C). (2)In November 2014, Spain enacted corporate tax reform that changed the corporate tax rate from 30% in 2014 to 28% in 2015 to 25% in 2016. As a result, Alcoa Corporation remeasured certain deferred tax assets related to Spanish operations. (3)In 2014, a tax holiday for a Brazilian entity of Alcoa Corporation became effective (see below). 158 (4)Hypothetical net operating losses and tax credits determined on a separate return basis for which it is more likely than not that a tax benefit will not be realized. The related deferred tax asset and offsetting valuation allowance have been adjusted to Parent Company net investment and, as such, are not reflected in subsequent deferred tax and valuation allowance tables. The components of net deferred tax assets and liabilities were as follows: 2016 2015 December 31, Deferred tax assets Deferred tax liabilities Deferred tax assets Deferred tax liabilities Depreciation $ 187 $499 $ 264 $ 529 Employee benefits 1,240 - 286 39 Loss provisions 313 - 302 7 Deferred income/expense 28 136 48 312 Tax loss carryforwards 1,064 - 992 - Tax credit carryforwards 23 - 15 - Derivatives and hedging activities - 124 - 216 Other 233 125 420 412 3,088 884 2,327 1,515 Valuation allowance (1,755) - (712) - $ 1,333 $884 $1,615 $1,515 The following table details the expiration periods of the deferred tax assets presented above: December 31, 2016 Expires within 10 years Expires within 11-20 years No expiration* Other* Total Tax loss carryforwards $ 282 $177 $ 605 $ - $ 1,064 Tax credit carryforwards 23 - - - 23 Other - - 361 1,640 2,001 Valuation allowance (272) (88) (265) (1,130) (1,755) $ 33 $ 89 $ 701 $ 510 $ 1,333 * Deferred tax assets with no expiration may still have annual limitations on utilization. Other represents deferred tax assets whose expiration is dependent upon the reversal of the underlying temporary difference. The total deferred tax asset (net of valuation allowance) is supported by projections of future taxable income exclusive of reversing temporary differences and taxable temporary differences that reverse within the carryforward period. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not (greater than 50%) that a tax benefit will not be realized. In evaluating the need for a valuation allowance, management considers all potential sources of taxable income, including income available in carryback periods, future reversals of taxable temporary differences, projections of taxable income, and income from tax planning strategies, as well as all available positive and negative evidence. Positive evidence includes factors such as a history of profitable operations, projections of future profitability within the carryforward period, including from tax planning strategies, and Alcoa Corporation’s experience with similar operations. Existing favorable contracts and the ability to sell products into established markets are additional positive evidence. Negative evidence includes items such as cumulative losses, projections of future losses, or carryforward periods that are not long enough to allow for the utilization of a deferred tax asset based on existing projections of income. In certain jurisdictions, deferred tax assets related to cumulative losses exist without a valuation allowance where in management’s judgment the weight of the positive evidence more than offsets the 159 negative evidence of the cumulative losses. Upon changes in facts and circumstances, management may conclude that deferred tax assets for which no valuation allowance is currently recorded may not be realized, resulting in a future charge to establish a valuation allowance. Existing valuation allowances are re-examined under the same standards of positive and negative evidence. If it is determined that it is more likely than not that a deferred tax asset will be realized, the appropriate amount of the valuation allowance, if any, is released. Deferred tax assets and liabilities are also re-measured to reflect changes in underlying tax rates due to law changes and the granting and lapse of tax holidays. In 2013, Alcoa Corporation recognized a $128 discrete income tax charge for a valuation allowance on the full value of the deferred tax assets related to a Spanish consolidated tax group. These deferred tax assets have an expiration period ranging from 2017 (for certain credits) to an unlimited life (for operating losses). After weighing all available positive and negative evidence, as described above, management determined that it was no longer more likely than not that Alcoa Corporation will realize the tax benefit of these deferred tax assets. This was mainly driven by a decline in the outlook of the former Primary Metals business (2013 realized prices were the lowest since 2009) combined with prior year cumulative losses of the Spanish consolidated tax group. During 2014, the underlying value of the deferred tax assets decreased due to a remeasurement as a result of the enactment of new tax rates in Spain beginning in 2016 and a change in foreign currency exchange rates. As a result, the valuation allowance decreased by the same amount. At December 31, 2016 and 2015, the amount of the valuation allowance was $76 and $91, respectively. This valuation allowance was reevaluated as of December 31, 2016, and no change to the allowance was deemed necessary based on all available evidence. The need for this valuation allowance will be assessed on a continuous basis in future periods and, as a result, a portion or all of the allowance may be reversed based on changes in facts and circumstances. In 2015, Alcoa Corporation recognized an additional $141 discrete income tax charge for valuation allowances on certain deferred tax assets in Iceland and Suriname. Of this amount, an $85 valuation allowance was established on the full value of the deferred tax assets in Suriname, which were related mostly to employee benefits and tax loss carryforwards. These deferred tax assets have an expiration period ranging from 2017 to 2022. The remaining $56 charge relates to a valuation allowance established on a portion of the deferred tax assets recorded in Iceland. These deferred tax assets have an expiration period ranging from 2017 to 2023. After weighing all available positive and negative evidence, as described above, management determined that it was no longer more likely than not that Alcoa Corporation will realize the tax benefit of either of these deferred tax assets. This was mainly driven by a decline in the outlook of the former Primary Metals business, combined with prior year cumulative losses and a short expiration period. At December 31, 2016 and 2015, the amount of the combined valuation allowance remained $141. This valuation allowance was reevaluated as of December 31, 2016, and no change to the allowance was deemed necessary based on all available evidence. The need for this valuation allowance will be assessed on a continuous basis in future periods and, as a result, a portion or all of the allowance may be reversed based on changes in facts and circumstances. In December 2011, one of Alcoa Corporation’s subsidiaries in Brazil applied for a tax holiday related to its expanded mining and refining operations. During 2013, the application was amended and re-filed and, separately, a similar application was filed for one of the ParentCo’s subsidiaries in Brazil that has significant operations related to Alcoa Corporation. The deadline for the Brazilian government to deny the application was July 11, 2014. Since Alcoa Corporation did not receive notice that its applications were denied, the tax holiday took effect automatically on July 12, 2014. As a result, the tax rate for these entities decreased significantly (from 34% to 15.25%), resulting in future cash tax savings over the 10-year holiday period (retroactively effective as of January 1, 2013). Additionally, a portion of the Alcoa Corporation subsidiary’s net deferred tax asset that reverses within the holiday period was remeasured at the new tax rate (the net deferred tax asset of the other subsidiary was not remeasured since it could still be utilized against the subsidiary’s future earnings not subject to the tax holiday). In 2014, this remeasurement resulted in a decrease to that entity’s net deferred tax asset and a noncash charge to earnings of $52 ($31 after noncontrolling interest) in Alcoa Corporation’s Statement of Consolidated Operations. 160 The following table details the changes in the valuation allowance: December 31,2016 2015 2014 Balance at beginning of year $ (712) $(486) $(517) Increase to allowance (1,072) (289) (19) Release of allowance 16 - 7 U.S. state tax apportionment and tax rate changes - 30 15 Foreign currency translation 13 33 28 Balance at end of year $(1,755) $(712) $(486) The cumulative amount of Alcoa Corporation’s foreign undistributed net earnings for which no deferred taxes have been provided was approximately $790 at December 31, 2016. This amount only relates to foreign undistributed net earnings generated prior to the Separation Date. Alcoa Corporation has a number of commitments and obligations related to the Company’s operations in various foreign jurisdictions. As such, management has no plans to distribute such earnings in the foreseeable future, and, therefore, has determined it is not practicable to determine the related deferred tax liability. Alcoa Corporation is currently evaluating its local and global cash needs for future business operations and anticipated debt facilities, which may influence future repatriation decisions. A reconciliation of the beginning and ending amount of unrecognized tax benefits (excluding interest and penalties) was as follows: December 31,2016 2015 2014 Balance at beginning of year $22 $25 $ 52 Additions for tax positions of the current year 3 2 2 Additions for tax positions of prior years 1 1 1 Reductions for tax positions of prior years (2) - (1) Settlements with tax authorities (2) (2) (28) Expiration of the statute of limitations - - - Foreign currency translation 1 (4) (1) Balance at end of year $23 $22 $ 25 For all periods presented, a portion of the balance at end of year pertains to state tax liabilities, which are presented before any offset for federal tax benefits. The effect of unrecognized tax benefits, if recorded, that would impact the annual effective tax rate for 2016, 2015, and 2014 would be 10%, 4%, and 17%, respectively, of pretax book loss. Alcoa Corporation does not anticipate that changes in its unrecognized tax benefits will have a material impact on the Statement of Consolidated Operations during 2017 (see Tax in Note R for a matter for which no reserve has been recognized). It is Alcoa Corporation’s policy to recognize interest and penalties related to income taxes as a component of the Provision for income taxes on the accompanying Statement of Consolidated Operations. In 2016, 2015, and 2014, Alcoa Corporation recognized $1, $7, and $1, respectively, in interest and penalties. Due to the expiration of the statute of limitations, settlements with tax authorities, and refunded overpayments, Alcoa Corporation also recognized interest income of $2, $1, and $5 in 2016, 2015, and 2014, respectively. As of December 31, 2016 and 2015, the amount accrued for the payment of interest and penalties was $6 and $7, respectively. Q. Asset Retirement Obligations Alcoa Corporation has recorded AROs related to legal obligations associated with the normal operation of bauxite mines, alumina refineries, and aluminum smelters. These AROs consist primarily of costs associated with mine reclamation, closure of bauxite residue areas, spent pot lining disposal, and landfill closure. Alcoa Corporation also 161 recognizes AROs for any significant lease restoration obligation, if required by a lease agreement, and for the disposal of regulated waste materials related to the demolition of certain power facilities. In addition to AROs, certain CAROs related to alumina refineries, aluminum smelters, rolling mills, and energy generation facilities have not been recorded in the Consolidated Financial Statements due to uncertainties surrounding the ultimate settlement date. Such uncertainties exist as a result of the perpetual nature of the structures, maintenance and upgrade programs, and other factors. At the date a reasonable estimate of the ultimate settlement date can be made (e.g., planned demolition), Alcoa Corporation would record an ARO for the removal, treatment, transportation, storage, and/or disposal of various regulated assets and hazardous materials such as asbestos, underground and aboveground storage tanks, PCBs, various process residuals, solid wastes, electronic equipment waste, and various other materials. If Alcoa Corporation was required to demolish all such structures immediately, the estimated CARO as of December 31, 2016 ranges from $3 to $29 per structure (24 structures) in today’s dollars. The following table details the carrying value of recorded AROs by major category (of which $104 and $96 was classified as a current liability as of December 31, 2016 and 2015, respectively): December 31,2016 2015 Mine reclamation $199 $191 Closure of bauxite residue areas 219 165 Spent pot lining disposal 135 141 Demolition*121 103 Landfill closure 30 29 Other 46 $708 $635 * In 2016 and 2015, AROs were recorded as a result of management’s decision to permanently close and demolish certain structures (see Note D). The following table details the changes in the total carrying value of recorded AROs: December 31,2016 2015 Balance at beginning of year $635 $648 Accretion expense 19 18 Payments (47) (72) Liabilities incurred 117 96 Foreign currency translation and other (16) (55) Balance at end of year $708 $635 R. Contingencies and Commitments Unless specifically described to the contrary, all matters within Note R are the full responsibility of Alcoa Corporation pursuant to the Separation and Distribution Agreement (see Note A). Additionally, the Separation and Distribution Agreement provides for cross-indemnities between the Company and Arconic for claims subject to indemnification. Contingencies Litigation.On June 5, 2015, AWA and St. Croix Alumina, L.L.C. (“SCA”) filed a complaint in Delaware Chancery Court for a declaratory judgment and injunctive relief to resolve a dispute between ParentCo and Glencore Ltd. (“Glencore”) with respect to claimed obligations under a 1995 asset purchase agreement between ParentCo and Glencore. The dispute arose from Glencore’s demand that ParentCo indemnify it for liabilities it may have to pay to Lockheed Martin (“Lockheed”) related to the St. Croix alumina refinery. Lockheed had earlier filed suit against Glencore in federal court in New York seeking indemnity for liabilities it had incurred and would incur to the U.S. 162 Virgin Islands to remediate certain properties at the refinery property and claimed that Glencore was required by an earlier, 1989 purchase agreement to indemnify it. Glencore had demanded that ParentCo indemnify and defend it in the Lockheed case and threatened to claim against ParentCo in the New York action despite exclusive jurisdiction for resolution of disputes under the 1995 purchase agreement being in Delaware. After Glencore conceded that it was not seeking to add ParentCo to the New York action, AWA and SCA dismissed their complaint in the Chancery Court case and on August 6, 2015 filed a complaint for declaratory judgment in Delaware Superior Court. AWA and SCA filed a motion for judgment on the pleadings on September 16, 2015. Glencore answered AWA’s and SCA’s complaint and asserted counterclaims on August 27, 2015, and on October 2, 2015 filed its own motion for judgment on the pleadings. Argument on the parties’ motions was held by the court on December 7, 2015, and by order dated February 8, 2016, the court granted ParentCo’s motion and denied Glencore’s motion, resulting in ParentCo not being liable to indemnify Glencore for the Lockheed action. The decision also leaves for pretrial discovery and possible summary judgment or trial Glencore’s claims for costs and fees it incurred in defending and settling an earlier Superfund action brought against Glencore by the Government of the Virgin Islands. On February 17, 2016, Glencore filed notice of its application for interlocutory appeal of the February 8, 2016 ruling. AWA and SCA filed an opposition to that application on February 29, 2016. On March 10, 2016, the court denied Glencore’s motion for interlocutory appeal and on the same day entered judgment on claims other than Glencore’s claims for costs and fees it incurred in defending and settling the earlier Superfund action brought against Glencore by the Government of the Virgin Islands. On March 29, 2016, Glencore filed a withdrawal of its notice of interlocutory appeal, and on April 6, 2016, Glencore filed an appeal of the court’s March 10, 2016 judgment to the Delaware Supreme Court, which set the appeal for argument for November 2, 2016. On November 4, 2016, the Delaware Supreme Court affirmed the judgment of the Delaware Superior Court granting ParentCo’s motion. Remaining in the case were Glencore’s claims for costs and fees it incurred related to the previously described Superfund action. On March 7, 2017, Alcoa Corporation and Glencore agreed in principle to settle these claims and expect to request the court to dismiss the case prior to the court’s scheduled March 21, 2017 conference. The amount of the proposed settlement is not material. Before 2002, ParentCo purchased power in Italy in the regulated energy market and received a drawback of a portion of the price of power under a special tariff in an amount calculated in accordance with a published resolution of the Italian Energy Authority, Energy Authority Resolution n. 204/1999 (“204/1999”). In 2001, the Energy Authority published another resolution, which clarified that the drawback would be calculated in the same manner, and in the same amount, in either the regulated or unregulated market. At the beginning of 2002, ParentCo left the regulated energy market to purchase energy in the unregulated market. Subsequently, in 2004, the Energy Authority introduced regulation no. 148/2004, which set forth a different method for calculating the special tariff that would result in a different drawback for the regulated and unregulated markets. ParentCo challenged the new regulation in the Administrative Court of Milan and received a favorable judgment in 2006. Following this ruling, ParentCo continued to receive the power price drawback in accordance with the original calculation method, through 2009, when the European Commission declared all such special tariffs to be impermissible “state aid.” In 2010, the Energy Authority appealed the 2006 ruling to the Consiglio di Stato (final court of appeal). On December 2, 2011, the Consiglio di Stato ruled in favor of the Energy Authority and against ParentCo, thus presenting the opportunity for the energy regulators to seek reimbursement from ParentCo of an amount equal to the difference between the actual drawback amounts received over the relevant time period, and the drawback as it would have been calculated in accordance with regulation 148/2004. On February 23, 2012, ParentCo filed its appeal of the decision of the Consiglio di Stato (this appeal was subsequently withdrawn in March 2013). On March 26, 2012, ParentCo received a letter from the agency (Cassa Conguaglio per il Settore Eletrico (CCSE)) responsible for making and collecting payments on behalf of the Energy Authority demanding payment in the amount of approximately $110 (€85), including interest. By letter dated April 5, 2012, ParentCo informed CCSE that it disputes the payment demand of CCSE since (i) CCSE was not authorized by the Consiglio di Stato decisions to seek payment of any amount, (ii) the decision of the Consiglio di Stato has been appealed (see above), and (iii) in any event, no interest should be payable. On April 29, 2012, Law No. 44 of 2012 (“44/2012”) came into effect, changing the method to calculate the drawback. On February 21, 2013, ParentCo received a revised request letter from CSSE demanding ParentCo’s former subsidiary, Alcoa Trasformazioni S.r.l. (Trasformazioni is now a subsidiary of Alcoa Corporation), make a payment in the amount of $97 (€76), including interest, which reflects a revised calculation methodology by CCSE and represents the high end of the range of reasonably possible loss associated with this matter of $0 to $97 (€76). ParentCo rejected that demand and formally 163 challenged it through an appeal before the Administrative Court on April 5, 2013. The Administrative Court scheduled a hearing for December 19, 2013, which was subsequently postponed until April 17, 2014, and further postponed until June 19, 2014. On this date, the Administrative Court listened to ParentCo’s oral argument, and on September 2, 2014, rendered its decision. The Administrative Court declared the payment request of CCSE and the Energy Authority to ParentCo to be unsubstantiated based on the 148/2004 resolution with respect to the January 19, 2007 through November 19, 2009 timeframe. On December 18, 2014, the CCSE and the Energy Authority appealed the Administrative Court’s September 2, 2014 decision; however, a date for the hearing has not been scheduled. As a result of the conclusion of the European Commission Matter on January 26, 2016 (see below), ParentCo’s management modified its outlook with respect to a portion of the pending legal proceedings related to this matter. As such, a charge of $37 (€34) was recorded in Restructuring and other charges for the year ended December 31, 2015 on Alcoa Corporation’s accompanying Statement of Consolidated Operations to establish a partial reserve for this matter. At this time, Alcoa Corporation is unable to reasonably predict the ultimate outcome for this matter. European Commission Matter.In July 2006, the European Commission (EC) announced that it had opened an investigation to establish whether an extension of the regulated electricity tariff granted by Italy to some energy- intensive industries complied with European Union (EU) state aid rules. The Italian power tariff extended the tariff that was in force until December 31, 2005 through November 19, 2009 (ParentCo had been incurring higher power costs at its smelters in Italy subsequent to the tariff end date through the end of 2012). The extension was originally through 2010, but the date was changed by legislation adopted by the Italian Parliament effective on August 15, 2009. Prior to expiration of the tariff in 2005, ParentCo had been operating in Italy for more than 10 years under a power supply structure approved by the EC in 1996. That measure provided a competitive power supply to the primary aluminum industry and was not considered state aid from the Italian Government. The EC’s announcement expressed concerns about whether Italy’s extension of the tariff beyond 2005 was compatible with EU legislation and potentially distorted competition in the European market of primary aluminum, where energy is an important part of the production costs. On November 19, 2009, the EC announced a decision in this matter stating that the extension of the tariff by Italy constituted unlawful state aid, in part, and, therefore, the Italian Government is to recover a portion of the benefit ParentCo received since January 2006 (including interest). The amount of this recovery was to be based on a calculation prepared by the Italian Government (see below). In late 2009, after discussions with legal counsel and reviewing the bases on which the EC decided, including the different considerations cited in the EC decision regarding ParentCo’s two smelters in Italy, ParentCo recorded a charge of $250 (€173), which included $20 (€14) to write off a receivable from the Italian Government for amounts due under the now expired tariff structure and $230 (€159) to establish a reserve. On April 19, 2010, ParentCo filed an appeal of this decision with the General Court of the EU (see below). Prior to 2012, ParentCo was involved in other legal proceedings related to this matter that separately sought the annulment of the EC’s July 2006 decision to open an investigation alleging that such decision did not follow the applicable procedural rules and requested injunctive relief to suspend the effectiveness of the EC’s November 19, 2009 decision. However, the decisions by the General Court, and subsequent appeals to the European Court of Justice, resulted in the denial of these remedies. In June 2012, ParentCo received formal notification from the Italian Government with a calculated recovery amount of $375 (€303); this amount was reduced by $65 (€53) for amounts owed by the Italian Government to ParentCo, resulting in a net payment request of $310 (€250). In a notice published in the Official Journal of the European Union on September 22, 2012, the EC announced that it had filed an action against the Italian Government on July 18, 2012 to compel it to collect the recovery amount (on October 17, 2013, the European Court of Justice ordered Italy to so collect). On September 27, 2012, ParentCo received a request for payment in full of the $310 (€250) by October 31, 2012. Following discussions with the Italian Government regarding the timing of such payment, ParentCo paid the requested amount in five quarterly installments of $69 (€50) beginning in October 2012 through December 2013. On October 16, 2014, ParentCo received notice from the General Court of the EU that its April 19, 2010 appeal of the EC’s November 19, 2009 decision was denied. On December 27, 2014, ParentCo filed an appeal of the General Court’s October 16, 2014 ruling to the European Court of Justice (ECJ). Following submission of the EC’s response to the appeal, on June 10, 2015, ParentCo filed a request for an oral hearing before the ECJ; no decision on that request was 164 received. On January 26, 2016, ParentCo was informed that the ECJ had dismissed ParentCo’s December 27, 2014 appeal of the General Court’s October 16, 2014 ruling. The dismissal of ParentCo’s appeal represents the conclusion of the legal proceedings in this matter. Prior to this dismissal, ParentCo had a noncurrent asset of $100 (€91) reflecting the excess of the total of the five payments made to the Italian Government over the reserve recorded in 2009. As a result, this noncurrent asset, along with the $58 (€53) for amounts owed by the Italian Government to ParentCo mentioned above plus $6 (€6) for interest previously paid, was written-off. A charge of $164 (€150) was recorded in Restructuring and other charges for the year ended December 31, 2015 on Alcoa Corporation’s accompanying Statement of Consolidated Operations (see Note D). As a result of the EC’s November 19, 2009 decision, ParentCo’s management had contemplated ceasing operations at its Italian smelters due to uneconomical power costs. In February 2010, ParentCo’s management agreed to continue to operate its smelters in Italy for up to six months while a long-term solution to address increased power costs could be negotiated. Over a portion of this time, a long-term solution was not able to be reached related to the Fusina smelter, therefore, in May 2010, ParentCo and the Italian Government agreed to a temporary idling of the Fusina smelter. As of September 30, 2010, the Fusina smelter was fully curtailed (44,000 metric-tons-per-year). For the Portovesme smelter, ParentCo executed a new power agreement effective September 1, 2010 through December 31, 2012, replacing the short-term, market-based power contract that was in effect since early 2010. This new agreement along with interruptibility rights (i.e. compensation for power interruptions when grids are overloaded) granted to ParentCo for the Portovesme smelter provided additional time to negotiate a long-term solution (the EC had previously determined that the interruptibility rights were not considered state aid). At the end of 2011, as part of a restructuring of ParentCo’s global smelting system, ParentCo’s management decided to curtail operations at the Portovesme smelter during 2012 due to the uncertain prospects for viable, long-term power, along with rising raw materials costs and falling global aluminum prices (mid-2011 to late 2011). As of December 31, 2012, the Portovesme smelter was fully curtailed (150,000 metric-tons-per-year). In June 2013 and August 2014, ParentCo decided to permanently shut down and demolish the Fusina and Portovesme smelters, respectively, due to persistent uneconomical conditions (see Note D). Environmental Matters.Alcoa Corporation participates in environmental assessments and cleanups at a number of locations. These include owned or operating facilities and adjoining properties, previously owned or operating facilities and adjoining properties, and waste sites, including Superfund (Comprehensive Environmental Response, Compensation and Liability Act (CERCLA)) sites. A liability is recorded for environmental remediation when a cleanup program becomes probable and the costs can be reasonably estimated. As assessments and cleanups proceed, the liability is adjusted based on progress made in determining the extent of remedial actions and related costs. The liability can change substantially due to factors such as, among others, the nature and extent of contamination, changes in remedial requirements, and technological changes. Alcoa Corporation’s remediation reserve balance was $324 and $235 at December 31, 2016 and 2015 (of which $60 and $28 was classified as a current liability), respectively, and reflects the most probable costs to remediate identified environmental conditions for which costs can be reasonably estimated. In 2016, the remediation reserve was increased by $39 due to a charge of $26 related to the planned demolition of the Suriname refinery and permanent closure of the related bauxite mines (see Note D) and a net charge of $13 associated with a number of other sites. In 2015, the remediation reserve was increased by $107 due to a charge of $52 related to the planned demolition of the remaining structures at the Massena East smelter location (see Note D), a charge of $29 related to the planned demolition of the Poços de Caldas smelter and the Anglesea power station (see Note D), a charge of $12 related to the Mosjøen location (see below), a charge of $7 related to the Portovesme location (see below), and a net charge of $7 associated with a number of other sites. Of the changes to the remediation reserve in 2016 and 2015, $26 and $86, respectively, was recorded in Restructuring and other charges, while the remainder was recorded in Cost of goods sold on the accompanying Statement of Consolidated Operations. 165 Payments related to remediation expenses applied against the reserve were $32 and $24 in 2016 and 2015, respectively. These amounts include expenditures currently mandated, as well as those not required by any regulatory authority or third party. In 2016, the change in the reserve also reflects an increase for each of the following: $60 of obligations transferred from ParentCo in connection with the Separation Transaction (see Note A) on November 1, 2016, including Sherwin and East St. Louis described below; $17 for the reclassification of amounts included in other reserves within Other noncurrent liabilities and deferred credits on Alcoa Corporation’s Consolidated Balance Sheet as of December 31, 2015; and $5 due to the effects of foreign currency translation. In 2015, the change in the reserve also reflects a decrease of $13 due to the effects of foreign currency translation. Included in annual operating expenses are the recurring costs of managing hazardous substances and environmental programs. These costs are estimated to be approximately 2% of cost of goods sold. The Separation and Distribution Agreement (see Note A) includes provisions for the assignment or allocation of environmental liabilities between Alcoa Corporation and Arconic, including certain remediation obligations associated with environmental matters. In general, the respective parties will be responsible for the environmental matters associated with their operations, and with the properties and other assets assigned to each. Additionally, the Separation and Distribution Agreement lists environmental matters with a shared responsibility between the two companies with an allocation of responsibility and the lead party responsible for management of each matter. For matters assigned to Alcoa Corporation under the Separation and Distribution Agreement, Alcoa Corporation has agreed to indemnify Arconic in whole or in part for environmental liabilities arising from operations prior to the Separation Date. The following discussion provides details regarding the current status of certain significant reserves related to current or former Alcoa Corporation sites. With the exception of the Fusina, Italy matter, Alcoa Corporation assumed full responsibility of the matters described below. Sherwin, TX—In connection with ParentCo’s sale of the Sherwin alumina refinery, which was required to be divested as part of ParentCo’s Reynolds merger in 2000, ParentCo agreed to retain responsibility for the remediation of the then existing environmental conditions, as well as a pro rata share of the final closure of the active bauxite residue waste disposal areas (known as the Copano facility). This obligation was transferred from ParentCo to Alcoa Corporation as part of the Separation Transaction (see Note A) on November 1, 2016. Alcoa Corporation’s share of the closure costs is proportional to the total period of operation of the active waste disposal areas. At December 31, 2016, the reserve balance associated with Sherwin was $30. Approximately half of the project funding is expected to be spent through 2019 with the balance dependent on the schedule to complete closure of the waste disposal areas. Baie Comeau, Quebec, Canada—In August 2012, ParentCo presented an analysis of remediation alternatives to the Quebec Ministry of Sustainable Development, Environment, Wildlife and Parks (MDDEP), in response to a previous request, related to known polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) contained in sediments of the Anse du Moulin bay. As such, ParentCo increased the reserve for Baie Comeau by $25 in 2012 to reflect the estimated cost of ParentCo’s recommended alternative, consisting of both dredging and capping of the contaminated sediments. In July 2013, ParentCo submitted the Environmental Impact Assessment for the project to the MDDEP. The MDDEP notified ParentCo that the project as it was submitted was approved and a final mistrial decree was issued in July 2015. As a result, no further adjustment to the reserve was required in 2015. The decree provided final approval for the project and ParentCo began work on the final project design with construction on the project expected to begin in April 2017. At December 31, 2016 and 2015, the reserve balance associated with this matter was $24 and $26, respectively. Fusina and Portovesme, Italy—In 1996, ParentCo acquired the Fusina smelter and rolling operations and the Portovesme smelter, both of which were owned by ParentCo’s former subsidiary Alcoa Trasformazioni S.r.l. (“Trasformazioni”) (Trasformazioni is now a subsidiary of Alcoa Corporation and owns the Fusina smelter and Portovesme smelter sites, and Fusina Rolling S.r.l., a new ParentCo subsidiary, owns the Fusina rolling operations), from Alumix, an entity owned by the Italian Government. At the time of the acquisition, Alumix indemnified ParentCo for pre-existing environmental contamination at the sites. In 2004, the Italian Ministry of Environment and Protection of Land and Sea (MOE) issued orders to Trasformazioni and Alumix for the development of a clean-up plan related to 166 soil contamination in excess of allowable limits under legislative decree and to institute emergency actions and pay natural resource damages. Trasformazioni appealed the orders and filed suit against Alumix, among others, seeking indemnification for these liabilities under the provisions of the acquisition agreement. In 2009, Ligestra S.r.l. (“Ligestra”), Alumix’s successor, and Trasformazioni agreed to a stay of the court proceedings while investigations were conducted and negotiations advanced towards a possible settlement. In December 2009, Trasformazioni and Ligestra reached an initial agreement for settlement of the liabilities related to the Fusina operations while negotiations continued related to Portovesme (see below). The agreement outlined an allocation of payments to the MOE for emergency action and natural resource damages and the scope and costs for a proposed soil remediation project, which was formally presented to the MOE in mid-2010. The agreement was contingent upon final acceptance of the remediation project by the MOE. As a result of entering into this agreement, ParentCo increased the reserve by $12 in 2009 for Fusina. Based on comments received from the MOE and local and regional environmental authorities, Trasformazioni submitted a revised remediation plan in the first half of 2012; however, such revisions did not require any change to the existing reserve. In October 2013, the MOE approved the project submitted by ParentCo, resulting in no adjustment to the reserve. In January 2014, in anticipation of ParentCo reaching a final administrative agreement with the MOE, ParentCo and Ligestra entered into a final agreement related to Fusina for allocation of payments to the MOE for emergency action and natural resource damages and the costs for the approved soil remediation project. The agreement resulted in Ligestra assuming 50% to 80% of all payments and remediation costs. On February 27, 2014, ParentCo and the MOE reached a final administrative agreement for conduct of work. The agreement includes both a soil and groundwater remediation project estimated to cost $33 (€24) and requires payments of $25 (€18) to the MOE for emergency action and natural resource damages. Based on the final agreement with Ligestra, ParentCo’s share of all costs and payments was $17 (€12), of which $9 (€6) related to the damages will be paid annually over a 10-year period, which began in April 2014, and was previously fully reserved. The soil remediation project will begin once authorization to dispose of excavated waste into a third-party landfill is received from the MOE, which is expected at some point in the remainder of 2017. The responsibility for the execution of groundwater remediation project/emergency containment has been transferred to the MOE in accordance with the February 2014 settlement agreement and remediation is slated to begin in late 2017 or in 2018. Effective with the Separation Transaction (see Note A), Arconic retained the portion of this obligation related to the Fusina rolling operations. Specifically, under the Separation and Distribution Agreement, Trasformazioni, and with it the Fusina properties, were assigned to Alcoa Corporation. Fusina Rolling S.r.l., entered into a lease agreement for the portion of property that included the rolling operation. Pursuant to the Separation and Distribution Agreement, the liabilities at Fusina described above were allocated between Alcoa Corporation (Trasformazioni) and Arconic (Fusina Rolling S.r.l.). Arconic will pay $7 (€7) for the portion of remediation expenses associated with the section of property that includes the rolling operation. Separately, in 2009, due to additional information derived from the site investigations conducted at Portovesme, ParentCo increased the reserve by $3. In November 2011, Trasformazioni and Ligestra reached an agreement for settlement of the liabilities related to Portovesme, similar to the one for Fusina. A proposed soil remediation project for Portovesme was formally presented to the MOE in June 2012. Neither the agreement with Ligestra nor the proposal to the MOE resulted in a change to the reserve for Portovesme. In November 2013, the MOE rejected the proposed soil remediation project and requested a revised project be submitted. In May 2014, Trasformazioni and Ligestra submitted a revised soil remediation project that addressed certain stakeholders’ concerns. ParentCo increased the reserve by $3 in 2014 to reflect the estimated higher costs associated with the revised soil remediation project, as well as current operating and maintenance costs of the Portovesme site. In October 2014, the MOE required a further revised project be submitted to reflect the removal of a larger volume of contaminated soil than what had been proposed, as well as design changes for the cap related to the remaining contaminated soil left in place and the expansion of an emergency containment groundwater pump and treatment system that was previously installed. Trasformazioni and Ligestra submitted the further revised soil remediation project in February 2015. As a result, ParentCo increased the reserve by $7 in March 2015 to reflect the increase in the estimated costs of the project. In October 2015, ParentCo received a final ministerial decree approving the February 2015 revised soil remediation project. Work on the soil remediation project commenced in mid-2016 and is expected to 167 be completed in 2019. After further discussions with the MOE regarding the groundwater remediation project, Alcoa Corporation and Ligestra are working to find a common remediation solution. The ultimate outcome of this matter may result in a change to the existing reserve for Portovesme. Mosjøen, Norway—In September 2012, ParentCo presented an analysis of remediation alternatives to the Norwegian Environmental Agency (NEA) (formerly the Norwegian Climate and Pollution Agency, or “Klif”), in response to a previous request, related to known PAHs in the sediments located in the harbor and extending out into the fjord. As such, ParentCo increased the reserve for Mosjøen by $20 in 2012 to reflect the estimated cost of the baseline alternative for dredging of the contaminated sediments. A proposed project reflecting this alternative was formally presented to the NEA in June 2014, and was resubmitted in late 2014 to reflect changes by the NEA. The revised proposal did not result in a change to the reserve for Mosjøen. In April 2015, the NEA notified ParentCo that the revised project was approved and required submission of the final project design before issuing a final order. ParentCo completed and submitted the final project design, which identified a need to stabilize the related wharf structure to allow for the sediment dredging in the harbor. As a result, ParentCo increased the reserve for Mosjøen by $11 in June 2015 to reflect the estimated cost of the wharf stabilization. Also in June 2015, the NEA issued a final order approving the project as well as the final project design. In September 2015, ParentCo increased the reserve by $1 to reflect the potential need (based on prior experience with similar projects) to perform additional dredging if the results of sampling, which is required by the order, don’t achieve the required cleanup levels. Project construction commenced in early 2016 and is expected to be completed by the end of 2017. At December 31, 2016 and 2015, the reserve balance associated with this matter was $8 and $20, respectively. East St. Louis, IL—ParentCo had an ongoing remediation project related to an area used for the disposal of bauxite residue from former alumina refining operations. The project, which was selected by the EPA in a Record of Decision (ROD) issued in July 2012, is aimed at implementing a soil cover over the affected area. On November 1, 2013, the U.S. Department of Justice lodged a consent decree on behalf of the U.S. Environmental Protection Agency (EPA) for ParentCo to conduct the work outlined in the ROD. This consent decree was entered as final in February 2014 by the U.S. Department of Justice. As a result, ParentCo began construction in March 2014; the fieldwork on this project was completed by the end of June 2016. The completion report was approved by the EPA in September 2016 and this matter has now transitioned into a long-term (approximately 30 years) inspection, maintenance, and monitoring program. This obligation was transferred from ParentCo to Alcoa Corporation as part of the Separation Transaction (see Note A) on November 1, 2016. At December 31, 2016, the reserve balance associated with this matter was $4. Tax.In September 2010, following a corporate income tax audit covering the 2003 through 2005 tax years, an assessment was received as a result of Spain’s tax authorities disallowing certain interest deductions claimed by a Spanish consolidated tax group owned by ParentCo. An appeal of this assessment in Spain’s Central Tax Administrative Court by ParentCo was denied in October 2013. In December 2013, ParentCo filed an appeal of the assessment in Spain’s National Court. Additionally, following a corporate income tax audit of the same Spanish tax group for the 2006 through 2009 tax years, Spain’s tax authorities issued an assessment in July 2013 similarly disallowing certain interest deductions. In August 2013, ParentCo filed an appeal of this second assessment in Spain’s Central Tax Administrative Court, which was denied in January 2015. ParentCo filed an appeal of this second assessment in Spain’s National Court in March 2015. At December 31, 2016, the combined assessments, including interest, total $258 (€246). On January 16, 2017, Spain’s National Court issued a decision in favor of the Company related to the assessment received in September 2010. On March 6, 2017, the Company was notified that Spain’s tax authorities did not file an appeal, for which the deadline has passed. As a result, the assessment related to the 2003 through 2005 tax years is null and void. Spain’s National Court has not yet rendered a decision related to the assessment received in July 2013 for the 2006 through 2009 tax years. The amount of this assessment on a standalone basis, including interest, was $136 (€130) as of December 31, 2016. 168 The Company believes it has meritorious arguments to support its tax position and intends to vigorously litigate the remaining assessment through Spain’s court system. However, in the event the Company is unsuccessful, a portion of the remaining assessment may be offset with existing net operating losses available to the Spanish consolidated tax group, which would be shared between the Company and Arconic as provided for in the Tax Matters Agreement related to the Separation Transaction. Additionally, it is possible that the Company may receive similar assessments for tax years subsequent to 2009. Despite the favorable decision received on the first assessment, at this time, the Company is unable to reasonably predict the ultimate outcome for this matter. In March 2013, AWAB was notified by the Brazilian Federal Revenue Office (RFB) that approximately $110 (R$220) of value added tax credits previously claimed are being disallowed and a penalty of 50% assessed. Of this amount, AWAB received $41 (R$82) in cash in May 2012. The value added tax credits were claimed by AWAB for both fixed assets and export sales related to the Juruti bauxite mine and São Luís refinery expansion. The RFB has disallowed credits they allege belong to the consortium in which AWAB owns an interest and should not have been claimed by AWAB. Credits have also been disallowed as a result of challenges to apportionment methods used, questions about the use of the credits, and an alleged lack of documented proof. AWAB presented defense of its claim to the RFB on April 8, 2013. If AWAB is successful in this administrative process, the RFB would have no further recourse. If unsuccessful in this process, AWAB has the option to litigate at a judicial level. Separately from the AWAB’s administrative appeal, in June 2015, new tax law was enacted repealing the provisions in the tax code that were the basis for the RFB assessing a 50% penalty in this matter. As such, the estimated range of reasonably possible loss is $0 to $32 (R$103), whereby the maximum end of this range represents the portion of the disallowed credits applicable to the export sales and excludes the 50% penalty. Additionally, the estimated range of disallowed credits related to AWAB’s fixed assets is $0 to $36 (R$117), which would increase the net carrying value of AWAB’s fixed assets if ultimately disallowed. It is Alcoa Corporation’s management’s opinion that the allegations have no basis; however, at this time, management is unable to reasonably predict the ultimate outcome for this matter. Between 2000 and 2002, Alumínio sold approximately 2,000 metric tons of metal per month from its Poços de Caldas facility, located in the State of Minas Gerais (the “State”), to Alfio, a customer also located in the State. Sales in the State were exempted from value-added tax (VAT) requirements. Alfio subsequently sold metal to customers outside of the State, but did not pay the required VAT on those transactions. In July 2002, Alumínio received an assessment from State auditors on the theory that Alumínio should be jointly and severally liable with Alfio for the unpaid VAT. In June 2003, the administrative tribunal found Alumínio liable, and Alumínio filed a judicial case in the State in February 2004 contesting the finding. In May 2005, the Court of First Instance found Alumínio solely liable, and a panel of a State appeals court confirmed this finding in April 2006. Alumínio filed a special appeal to the Superior Tribunal of Justice (STJ) in Brasilia (the federal capital of Brazil) later in 2006. In 2011, the STJ (through one of its judges) reversed the judgment of the lower courts, finding that Alumínio should neither be solely nor jointly and severally liable with Alfio for the VAT, which ruling was then appealed by the State. In August 2012, the STJ agreed to have the case reheard before a five-judge panel. On February 21, 2017, the lead judge of the STJ issued a ruling confirming that Alumínio should be held liable in this matter. Alumínio is in the process of filing an appeal to have its case reheard before the five-judge panel as originally agreed to by the STJ in August 2012. At December 31, 2016, the assessment totaled $43 (R$142), including penalties and interest. While Alcoa Corporation believes it has meritorious defenses, the Company is unable to reasonably predict the ultimate outcome for this matter. Other.In connection with ParentCo’s sale in 2001 of Reynolds Metals Company’s (“Reynolds,” a subsidiary of Alcoa Corporation), alumina refinery in Gregory, Texas, Reynolds assigned an Energy Services Agreement (“ESA”) with Gregory Power Partners (“Gregory Power”) for purchase of steam and electricity by the refinery. On January 11, 2016, Sherwin Alumina Company, LLC (“Sherwin”), the current owner of the refinery, and one of its affiliate entities, filed bankruptcy petitions in Corpus Christi, Texas for reorganization under Chapter 11 of the Bankruptcy Code. On January 26, 2016, Gregory Power delivered notice to Reynolds that Sherwin’s bankruptcy filing constitutes a breach of the ESA; on January 29, 2016, Reynolds responded that the filing does not constitute a breach. Sherwin informed the bankruptcy court that it intends to cease operations because it is not able to continue its bauxite supply agreement, and, thereafter, Gregory Power filed a complaint in the bankruptcy case against Reynolds alleging breach of the ESA. This matter is neither estimable nor probable; therefore, at this time, Alcoa Corporation is unable to reasonably predict the ultimate outcome. 169 On October 4, 2016, the state of Texas filed suit against Sherwin in the bankruptcy proceeding seeking to hold Sherwin responsible for remediation of alleged environmental conditions at the facility. On October 11, 2016, Sherwin filed a similar suit against Reynolds in the case. On November 10, 2016, Reynolds filed motions to dismiss the Gregory Power complaint and to withdraw the case from bankruptcy court. On November 23, 2016, the bankruptcy court approved Sherwin’s plans for cessation of its operations. On February 16, 2017, Sherwin filed a bankruptcy Chapter 11 Plan and on February 17, 2017 the court approved that Plan. As provided in the Plan, Sherwin, including certain affiliated companies, and Reynolds are negotiating a settlement to allocate among them ownership of and responsibility for certain areas of the refinery. A definitive agreement is anticipated prior to April 30, 2017 and would resolve outstanding claims made by Sherwin against Reynolds. General.In addition to the matters discussed above, various other lawsuits, claims, and proceedings have been or may be instituted or asserted against Alcoa Corporation, including those pertaining to environmental, product liability, safety and health, and tax matters. While the amounts claimed in these other matters may be substantial, the ultimate liability cannot now be determined because of the considerable uncertainties that exist. Therefore, it is possible that the Company’s liquidity or results of operations in a particular period could be materially affected by one or more of these other matters. However, based on facts currently available, management believes that the disposition of these other matters that are pending or asserted will not have a material adverse effect, individually or in the aggregate, on the financial position of the Company. Commitments Purchase Obligations.Alcoa Corporation is party to unconditional purchase obligations for energy that expire between 2028 and 2037. Commitments related to these contracts total $169 in 2017, $223 in 2018, $231 in 2019, $237 in 2020, $245 in 2021, and $3,286 thereafter. Expenditures under these contracts totaled $181 in 2016, $125 in 2015, and $172 in 2014. Additionally, Alcoa Corporation has entered into other purchase commitments for energy, raw materials, and other goods and services, which total $1,934 in 2017, $1,560 in 2018, $1,528 in 2019, $1,309 in 2020, $1,237 in 2021, and $8,961 thereafter. On April 8, 2015, AofA secured a new 12-year gas supply agreement to power its three alumina refineries in Western Australia beginning in July 2020. This agreement was conditional on the completion of a third-party acquisition of the related energy assets from the then-current owner, which occurred in June 2015. The terms of the gas supply agreement required AofA to make a prepayment of $500 in two installments. The first installment of $300 was made at the time of the completion of the third-party acquisition in June 2015 and the second installment of $200 was made in April 2016. Both of these amounts were included in (Increase) in noncurrent assets on the accompanying Statement of Consolidated Cash Flows in the respective periods. At December 31, 2016 and 2015, Alcoa Corporation has an asset of $471 (A$654) and $288 (A$395), respectively, representing the respective prepayments made under this agreement, which was included in Other noncurrent assets (see Note S) on the accompanying Consolidated Balance Sheet. Operating Leases.Certain land and buildings, alumina refinery process control technology, plant equipment, vehicles, and computer equipment are under operating lease agreements. Total expense for all leases was $90 in 2016, $98 in 2015, and $115 in 2014. Under long-term operating leases, minimum annual rentals are $98 in 2017, $78 in 2018, $62 in 2019, $47 in 2020, $39 in 2021, and $35 thereafter. Guarantees of Third Parties.At December 31, 2016, Alcoa Corporation has maximum potential future payments for guarantees issued on behalf of a third party of $354. These guarantees expire at various times between 2017 and 2024 and relate to project financing for the aluminum complex in Saudi Arabia (see Note H). Bank Guarantees and Letters of Credit.Alcoa Corporation has outstanding bank guarantees and letters of credit related to energy contracts, environmental obligations, legal and tax matters, outstanding debt, leasing obligations, workers compensation, and customs duties, among others. The total amount committed under these instruments, which automatically renew or expire at various dates between 2017 and 2021, was $444 at December 31, 2016. Additionally, 170 Arconic has outstanding bank guarantees and letters of credit related to Alcoa Corporation in the amount of $115 at December 31, 2016. In the event Arconic would be required to perform under any of these instruments, Arconic would be indemnified by Alcoa Corporation in accordance with the Separation and Distribution Agreement. Likewise, Alcoa Corporation has outstanding bank guarantees and letters of credit related to Arconic in the amount of $26 at December 31, 2016. In the event Alcoa Corporation would be required to perform under any of these instruments, Alcoa Corporation would be indemnified by Arconic in accordance with the Separation and Distribution Agreement. Surety Bonds.Alcoa Corporation has outstanding surety bonds primarily related to tax matters, contract performance, workers compensation, environmental-related matters, and customs duties. The total amount committed under these bonds, which automatically renew or expire at various dates, mostly in 2017, was $159 at December 31, 2016. Additionally, Arconic has outstanding surety bonds related to Alcoa Corporation in the amount of $22 at December 31, 2016. In the event Arconic would be required to perform under any of these instruments, Arconic would be indemnified by Alcoa Corporation in accordance with the Separation and Distribution Agreement. S.

Under the resolution, ParentCo and AWA agreed to pay a combined $384 over a four-year timeframe. Prior to the Separation Transaction, ParentCo and AWA paid $236 of the total amount. As part of the Separation and Distribution Agreement, Alcoa Corporation assumed ParentCo’s portion of the $148 remaining obligation. The $148 is to be paid in equal installments of $74 in each of January 2017 (paid on January 9th) and January 2018. Cash Flow Information Cash paid for interest and income taxes was as follows: 2016 2015 2014 Interest, net of amount capitalized $226 $270 $309 Income taxes, net of amount refunded $265 265 184 Noncash Financing and Investing Activities.In September 2016, ANHBV issued $1,250 in new senior notes (see Note L) in preparation for the Separation Transaction (see Note A). The net proceeds of $1,228 from the debt issuance were required to be placed in escrow contingent on completion of the Separation Transaction. As a result, the $1,228 of escrowed cash was recorded as restricted cash. The issuance of the new senior notes and the increase in restricted cash both in the amount of $1,228 were not reflected in the accompanying Statement of Consolidated Cash Flows as these represent noncash financing and investing activities, respectively. The subsequent release of the $1,228 from escrow occurred on October 31, 2016. This decrease in restricted cash was reflected in the accompanying Statement of Consolidated Cash Flows as a cash inflow in the Net change in restricted cash line item. T. Subsequent Events Management evaluated all activity of Alcoa Corporation and concluded that no subsequent events have occurred that would require recognition in the Consolidated Financial Statements or disclosure in the Notes to the Consolidated Financial Statements, except as described below. On February 1, 2017, the sale of Yadkin closed (see Note C) and Alcoa Corporation received $241 in net proceeds, of which $238 was remitted to Arconic (an additional $5 is expected to be received from the buyer and remitted to Arconic at a later date as a post-closing adjustment) as part of the Separation and Distribution Agreement (see Note A). In the first quarter of 2017, Alcoa Corporation will recognize a pretax gain of approximately $120. 172 Supplemental Financial Information (unaudited) Quarterly Data (in millions, except per-share amounts) First(1)Second(1)Third(1)Fourth(2)Year 2016 Sales $2,129 $2,323 $2,329 $2,537 $ 9,318 Net (loss) income $ (215) $ (12) $ 10 $ (129) $ (346) Net loss attributable to Alcoa Corporation $ (210) $ (55) $ (10) $ (125) $ (400) Earnings per share attributable to Alcoa Corporation common shareholders(3): Basic $(1.16) $(0.29) $(0.06) $(0.68) $ (2.19) Diluted $(1.16) $(0.29) $(0.06) $(0.68) $ (2.19) 2015 Sales $3,105 $2,964 $2,679 $2,451 $11,199 Net income (loss) $ 226 $ (12) $ (63) $ (890) $ (739) Net income (loss) attributable to Alcoa Corporation $ 166 $ (79) $ (124) $ (826) $ (863) Earnings per share attributable to Alcoa Corporation common shareholders(3): Basic $ 0.91 $(0.43) $(0.68) $(4.52) $ (4.73) Diluted $ 0.91 $(0.43) $(0.68) $(4.52) $ (4.73) (1)In preparing the Combined Financial Statements for the nine months ended September 30, 2016 and 2015, management discovered that the amounts for Research and development expenses previously reported for the six months ended June 30, 2016 and 2015 included an immaterial error due to an over-allocation of such expenses of $10 and $18, respectively. The amounts for Research and development expenses in the accompanying Statement of Consolidated Operations for the years ended December 31, 2016 and 2015 are correctly stated. Additionally, in preparing the Consolidated Financial Statements for the year ended December 31, 2016, management discovered that the amounts for Cost of goods sold previously reported for the three months ended March 31, 2016, six months ended June 30, 2016, and nine months ended September 30, 2016 included an immaterial error due to an under- allocation of LIFO expense of $7, $10, and $14, respectively. The amount for Cost of goods sold in the accompanying Statement of Consolidated Operations for the year ended December 31, 2016 is correctly stated. The Quarterly Data above has been revised to correct the periods impacted by these two immaterial errors. Additionally, financial information for the referenced prior periods not presented herein will be revised, as applicable, in future filings. (2)In the fourth quarter of 2016, Alcoa Corporation recorded restructuring and other charges of $209 (pretax), which were primarily related to the closure of the Suriname refinery and related bauxite mines and the impairment of an interest in a gas exploration field in Australia (see Note D). In the fourth quarter of 2015, Alcoa Corporation recorded restructuring and other charges of $686 (pretax), which were primarily related to closures and/or curtailments of a number of smelters and refineries (see Note D) and a charge for legal matters in Italy (see Note R). (3)Per share amounts are calculated independently for each period presented; therefore, the sum of the quarterly per share amounts may not equal the per share amounts for the year. 173
