## O. DERIVATIVE FINANCIAL INSTRUMENTS 

As part of its risk management strategy, the Company enters into derivative contracts to hedge against interest rate and foreign currency risk. 

Interest-Rate Contracts: The Company enters into various interest-rate contracts, including interest-rate swaps and cross currency interest-rate swaps. Interest-rate swaps involve the exchange of fixed for floating rate or floating for fixed rate interest payments based on the contractual notional amounts in a single currency. Cross currency interest-rate swaps involve the exchange of notional amounts and interest payments in different currencies. The Company is exposed to interest rate and exchange rate risk caused by market volatility as a result of its borrowing activities. The objective of these contracts is to mitigate the fluctuations on earnings, cash flows and fair value of borrowings. Net amounts paid or received are reflected as adjustments to interest expense. 

At December 31, 2011, the notional amount of the Company’s interest-rate contracts was $2,914.1. Notional maturities for all interest-rate contracts are $705.6 for 2012, $708.9 for 2013, $1,037.2 for 2014, $387.2 for 2015, $39.1 for 2016 and $36.1 thereafter. The majority of these contracts are floating to fixed swaps that effectively convert an equivalent amount of commercial paper and other variable rate debt to fixed rates. 

Foreign-Exchange Contracts:  The Company enters into foreign-exchange contracts to hedge certain anticipated transactions and assets and liabilities denominated in foreign currencies, particularly the Canadian dollar, the euro, the British pound, the Australian dollar and the Mexican peso. The objective is to reduce fluctuations in earnings and cash flows associated with changes in foreign currency exchange rates. At December 31, 2011, the notional amount of the outstanding foreign-exchange contracts was $185.7. Foreign-exchange contracts mature within one year.
