Receivables [Abstract]
Receivables	J. Receivables – Alcoa has three arrangements, each with a different financial institution, to sell certain customer receivables outright without recourse on a continuous basis. As of March 31, 2012, sold receivables in the amount of $219 under the three arrangements combined were uncollected. Alcoa services the customer receivables for the financial institutions at market rates; therefore, no servicing asset or liability was recorded. On March 30, 2012, Alcoa finalized a one-year arrangement with a financial institution to sell certain customer receivables without recourse on a revolving basis. The sale of such receivables will be completed through the use of a bankruptcy remote special purpose entity, which is a consolidated subsidiary of Alcoa. This arrangement provides for minimum funding of $50 up to a maximum of $250 for receivables sold. Under this arrangement, Alcoa sold $304 of customer receivables in exchange for $50 in cash and $254 of deferred purchase price, which is included in Other receivables on the accompanying Consolidated Balance Sheet. The deferred purchase price receivable was not reflected in the accompanying Statement of Consolidated Cash Flows as it represents a non-cash activity. The deferred purchase price receivable will be reduced as collections of the underlying receivables occur; however, as this is a revolving program, the sale of new receivables will result in an increase in the deferred purchase price receivable. Beginning in the second quarter of 2012, the changes in the deferred purchase price receivable will be reflected on a net basis in the cash from operations section of the accompanying Statement of Consolidated Cash Flows. The special purpose entity services the customer receivables for the financial institution at market rates; therefore, no servicing asset or liability was recorded.
