Debt [Abstract] |
Debt | E. Debt – In January 2012, Alcoa repaid the $322 in outstanding principal of its 6% Notes as scheduled using available cash on hand. Also in January 2012, Alcoa entered into two term loan agreements, totaling $350, with two separate financial institutions and a revolving credit agreement, providing a $100 credit facility, with a third financial institution. In February 2012, Alcoa entered into another revolving credit agreement, providing a $100 credit facility, with a fourth financial institution. The purpose of any borrowings under all four arrangements will be to provide working capital and for other general corporate purposes, including contributions to Alcoa's pension plans ($213 was contributed in the 2012 first quarter). The two term loans were fully drawn on the same dates as the agreements and are subject to an interest rate equivalent to the 3-month LIBOR plus a 1.5% margin. In February 2012, Alcoa borrowed the $100 under the first credit facility. This borrowing is subject to an interest rate equivalent to the 6-month LIBOR plus a 1.25% margin. The two term loans mature in July 2012 and the two revolving credit facilities expire in December 2012. The covenants contained in all four arrangements are the same as Alcoa's Five-Year Revolving Credit Agreement (see the Commercial Paper section of Note K to the Consolidated Financial Statements included in Alcoa's 2011 Form 10-K). Furthermore in January 2012, Alcoa's subsidiary, Alumínio, borrowed $280 in new loans with a weighted-average interest rate of 2.32% and a weighted-average maturity of 172 days from two financial institutions. The purpose of these borrowings is to support Alumínio's export operations. During the first quarter of 2012, $60 was repaid.
