Saudi Arabia Joint Venture—Alcoa Corporation and Ma’aden have a 30-year (from December 2009) joint venture shareholders agreement (automatic extension for an additional 20 years, unless the parties agree otherwise or unless earlier terminated) setting forth the terms for the development, construction, ownership, and operation of an integrated aluminum complex in Saudi Arabia. The project developed by the joint venture consists of a bauxite mine from the Al Ba’itha bauxite deposit in the northern part of Saudi Arabia, an alumina refinery, a primary aluminum smelter, and an aluminum rolling mill.

The joint venture is owned 74.9% by Ma’aden and 25.1% by Alcoa Corporation and originally consisted of three separate companies as follows: the bauxite mine and alumina refinery (MBAC), the smelter (MAC), and the rolling mill (MRC). In June 2019, Alcoa Corporation and Ma’aden amended the joint venture agreement that governs the operations of each of the three companies that comprise the joint venture. Under the terms of the agreement, Alcoa Corporation transferred its 25.1% interest in MRC to Ma’aden and, as a result, has no further direct or indirect equity interest in MRC. Refer to Note D for additional information related to the agreement amendment.

A number of Alcoa Corporation employees perform various types of services for the smelting and mining and refining companies as part of the operation of the fully integrated aluminum complex. At December 31, 2021 and 2020, the Company had an aggregate outstanding receivable of $2 and $5, respectively, from the smelting, rolling mill, and mining and refining companies for labor and other employee-related expenses.

As of December 31, 2021 and 2020, the carrying value of Alcoa’s investment in this joint venture was $687 and $559, respectively.

ELYSIS^TM Limited Partnership—In June 2018, Alcoa Corporation, Rio Tinto Alcan Inc. (Rio Tinto), and Investissement Québec, a company wholly-owned by the Government of Québec, Canada, launched a new joint venture, ELYSIS^TM Limited Partnership (ELYSIS^TM). The purpose of this partnership is to advance larger scale development and commercialization of its patent-protected technology that produces oxygen and eliminates all direct greenhouse gas emissions from the traditional aluminum smelting process. Alcoa and Rio Tinto plc, as general partners, each own a 48.235% stake in ELYSIS^TM, and the Québec provincial government, as a limited partner, owns a 3.53% stake. The federal government of Canada and Apple Inc., as well as the Québec provincial government, are providing initial financing to the partnership.

The total planned combined investment (equity and debt) of the five participants in the joint venture was updated in the fourth quarter of 2021 to $289 (C$369). Alcoa and Rio Tinto plc will each invest $76 (C$97) in the joint venture, as well as contribute and license certain intellectual property and patents to ELYSIS^TM. Through December 31, 2021, the Company has contributed $23 (C$30) toward its investment commitment in ELYSIS^TM. In addition to cash contributions, Alcoa is contributing approximately $3 annually to cover overhead expenses incurred by Alcoa and charged to the joint venture. The Company’s basis in the investment has been reduced to zero for its share of losses incurred to date. As a result, the Company has $55 in unrecognized losses as of December 31, 2021 that will be recognized upon additional contributions into the partnership.
