MARKET RISKS AND DERIVATIVE INSTRUMENTS  (currencies in millions) Interest-Rate Risks  –  See Note O for a description of the Company’s hedging programs and exposure to interest-rate  fluctuations.  The Company measures its interest-rate risk by estimating the amount by which the fair value of interest  rate sensitive assets and liabilities, including derivative financial instruments, would change assuming an immediate  100 basis point increase across the yield curve as shown in the following table: Currency Risks  – The Company enters into foreign currency exchange contracts to hedge its exposure to exchange  rate fluctuations of foreign currencies, particularly the Canadian dollar, the euro, the British pound and the  Mexican peso  (See Note O for additional information concerning these hedges) . Based on the Company’s sensitivity  analysis, the potential loss in fair value for such financial instruments from a 10% unfavorable change in quoted  foreign currency exchange rates would be a loss of $21.2 related to contracts outstanding at December 31, 2011,  compared to a loss of $15.0 at December 31, 2010. These amounts would be largely offset by changes in the values  of the underlying hedged exposures.
