ALCOA CORPORATION (NYSE:AA) Files An 8-K Costs Associated with Exit or Disposal Activities
Item 2.05 Costs Associated with Exit or Disposal Activities.

On December21, 2017, management of Alcoa Corporation (“Alcoa” or the “Company”) approved the permanent closure of the Rockdale smelter (capacity of 191,000 metric-tons-per-year) in Texas effective immediately. The Rockdale smelter has been fully curtailed since the end of 2008. Management of Alcoa’s former parent company, Alcoa Inc. (ParentCo), decided to curtail the operating capacity of the Rockdale smelter in 2008 as a result of an uncompetitive power supply and then-overall unfavorable market conditions. In October 2017, management of Alcoa negotiated with the counterparty an early termination of the power supply contract, which was set to expire no earlier than 2038. As a result of the early termination, Alcoa initiated a strategic review of the smelter and other related operations, which include a casthouse and aluminum powder plant, at the Rockdale site. Under this review, management of Alcoa determined that the Rockdale operations have limited economic prospects. This conclusion was the basis for the decision to permanently close the operations at the Rockdale site. Demolition and remediation activities related to this action will begin in 2018 and are expected to be completed by the end of 2022.

As a result of this decision, Alcoa expects to record restructuring-related charges of $55 million (pre- and after-tax, or $0.30 per diluted share) in the fourth quarter of 2017. These charges include $38 million for asset impairments to write off the remaining carrying value of various fixed assets and inventories, $16 million for asset retirement obligations and environmental remediation resulting from the decision to permanently close and demolish these facilities and related infrastructure, and $1 million for employee layoff costs. Additionally, Alcoa expects to record holding costs and demolition expenses of $23 million (pre- and after-tax) as incurred during the subsequent five-year timeframe (2018 through 2022).

Expected future cash outlays over the next five years related to the closure of the Rockdale operations total $53 million, including $16 million in 2018. The $53 million is comprised of the $17 million in 2017 fourth quarter charges for asset retirement obligations and environmental remediation and employee layoff costs, $13 million related to previously accrued asset retirement obligations, and the $23 million in estimated future holding costs and demolition expenses.

Amounts related to this action are still being finalized. Additional details will be provided in Alcoa’s Annual Report on Form10-K for the year ended December31, 2017. Also, it is possible that charges in addition to those described above may be recognized in future periods.

On December21, 2017, Alcoa and Invitalia, which is an Italian government agency responsible for managing economic development, reached an agreement to transfer ownership of the Portovesme smelter (permanently closed in 2014) in Italy from the Company to Invitalia. As part of this agreement, Alcoa and the Italian government have settled certain pre-existing matters, including an energy tariff dispute that has been subject to ongoing litigation and a groundwater remediation project.

The energy tariff dispute refers to Italian Energy Authority Regulation 148/2004, on which a hearing was scheduled for May 2018, and relates to both Alcoa’s Portovesme and Fusina (permanently closed in 2013) smelters. At the end of 2015, ParentCo recorded a charge to establish a partial reserve of $40 million (€34 million) in this matter (the U.S. dollar amount reflects the effects of foreign currency movements since 2015), which Alcoa Corporation assumed on November1, 2016. See Note M to the Consolidated Financial Statements included in Alcoa’s Quarterly Report on Form 10-Q for the period ended September30, 2017 for a full description of this matter.

As a result of this agreement, Alcoa expects to reduce the previously established reserve for the Italian Energy Authority Regulation 148/2004 matter by $22 million (pre- and after-tax, or $0.12 per diluted share) in the fourth quarter of 2017. Additionally, Alcoa will retain previously accrued asset retirement obligations, which may be reduced upon Invitalia reaching certain milestones related to the future of the Portovesme smelter. Expected future cash outlays over the next five years related to this agreement total between $40 million and $50 million, including $10 million in 2018.

The carrying value of the assets related to the Portovesme site were previously written down to zero as a result of ParentCo’s decision in 2014 to permanently close the smelter.

Amounts related to this agreement are still being finalized. Additional details will be provided in Alcoa’s Annual Report on Form 10-K for the year ended December31, 2017.

The information in Item 2.05 of this Current Report on Form 8-K is being filed in accordance with the provisions of General Instruction B.1 of Form 8-K.
