Explanation of Responses:
(1)	This disposition relates to shares of Alcoa Corporation stock held in the Arconic Inc. 401(k) plan (the "Arconic Qualified Plan"). On November 1, 2016, Alcoa Corporation launched as an independent, publicly traded company upon its separation from Alcoa Inc. (since renamed "Arconic Inc."). In connection with the separation transaction, on November 1, 2016, one share of Alcoa Corporation common stock was distributed by Alcoa Inc. for every three shares of Alcoa Inc. common stock held by its stockholders on the record date for the transaction. For a transition period following the separation transaction, the Alcoa Corporation stock fund remained an investment option in the Arconic Qualified Plan.
(2)	The reporting person, a former employee of Alcoa Inc., was advised by the plan administrator of the Arconic Qualified Plan that if the reporting person did not direct an intra-plan transfer of all assets held in the Alcoa Corporation stock fund of the Arconic Qualified Plan to another fund in the Arconic Qualified Plan by October 6, 2017, the reporting person's entire balance in the Alcoa Corporation stock fund of the Arconic Qualified Plan would be liquidated and invested into another fund designated by the plan administrator. Therefore, on September 13, 2017, the reporting person effected an intra-plan transfer of all assets held in the Alcoa Corporation stock fund to another plan fund under the Arconic Qualified Plan.
