Receivables	L. Receivables – Alcoa has an arrangement with three financial institutions to sell certain customer receivables without recourse on a revolving basis. The sale of such receivables is 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 $200 up to a maximum of $500 for receivables sold. On March 30, 2012, Alcoa initially sold $304 of customer receivables in exchange for $50 in cash and $254 of deferred purchase price under this arrangement. Alcoa has received additional net cash funding of $300 for receivables sold ($1,358 in draws and $1,058 in repayments) since the program’s inception. Draws and repayments in the 2016 first quarter were $100 and $0, respectively. As of March 31, 2016 and December 31, 2015, the deferred purchase price receivable was $210 and $249, respectively, which was included in Other receivables on the accompanying Consolidated Balance Sheet. The deferred purchase price receivable is 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. The net change in the deferred purchase price receivable was reflected in the (Increase) in receivables line item on the accompanying Statement of Consolidated Cash Flows. This activity is reflected as an operating cash flow because the related customer receivables are the result of an operating activity with an insignificant, short-term interest rate risk. The gross amount of receivables sold and total cash collected under this program since its inception was $26,055 and $25,495, respectively. Alcoa services the customer receivables for the financial institutions at market rates; therefore, no servicing asset or liability was recorded.
