The Finished goods, Work-in-process and Bauxite and alumina balances as of December 31, 2021 reported above reflect an adjustment related to a misclassification of an intercompany profit reserve previously presented in Work-in-process. This resulted in an increase in Work-in-process of $172 and reductions of $9 and $163 in Finished goods and Bauxite and alumina, respectively. This adjustment had no impact on the total Inventories balance as of December 31, 2021.
