[1] Includes notes payable, current maturities of long-term debt and long-term debt included on the Consolidated balance sheet. The increase in debt obligations from December 31, 2010 to December 31, 2011 was primarily due to net issuances of $1.0 billion.
[2] Aggregate maturities for 2011 debt balances, before fair value adjustments, were as follows (in millions): 2012-$366.6; 2013-$1,026.0; 2014-$737.9; 2015-$656.3; 2016-$2,158.6; Thereafter-$7,499.1. These amounts include a reclassification of short-term obligations totaling $1.5 billion to long-term obligations as they are supported by a long-term line of credit agreement expiring in November 2016.
[3] The carrying value of underlying items in fair value hedges, in this case debt obligations, are adjusted for fair value changes to the extent they are attributable to the risk designated as being hedged. The related hedging instrument is also recorded at fair value in prepaid expenses and other current assets, miscellaneous other assets or other long-term liabilities. A portion ($0.5 million) of the adjustments at December 31, 2011 related to interest rate swaps that were terminated in December 2002 and will amortize as a reduction of interest expense over the remaining life of the debt.
[4] Weighted-average effective rate, computed on a semi-annual basis.
[5] Primarily consists of Swiss Francs, Chinese Renminbi and Korean Won.
