Exhibit 10(v)

ARCONIC SUPPLEMENTAL PENSION PLAN FOR SENIOR EXECUTIVES

(as amended and restated August 1, 2016)

Alcoa Inc. has adopted the following Arconic Supplemental Pension Plan for Senior Executives as amended and restated effective August 1, 2016. This Excess Plan was formerly referred to as the Alcoa Supplemental Pension Plan for Senior Executives. Effective August 1, 2016, in anticipation of its separation into two separate publicly-traded companies, Alcoa Inc. separated this Excess Plan into two separate plans: this Excess Plan and the Alcoa USA Supplemental Pension Plan for Senior Executives. No person is entitled to a benefit under both plans.

This Excess Plan is for the exclusive benefit of select management and highly compensated employees (1) whose Pension Service terminates on or after January 1, 1999, (2) who are participants in the IC Rules adopted under Arconic Retirement Plan I and/or in the Arconic Employees’ Excess Benefits Plan B due to their previous participation in the IC Rules, (3) who meet the requirements for participation hereunder, and (4) whose monthly retirement benefits under other benefit plans are less than the monthly retirement benefits calculated under this Excess Plan. Effective December 31, 2007, this Excess Plan was frozen as to new participants, and only certain Participants as of that date will be eligible for a benefit accrual under this Excess Plan.
