Derivatives The Group enters into foreign exchange forward contracts to hedge foreign exchange risk associ- ated with certain assets and liabilities denominated in foreign currencies. The Group also enters into interest rate swap contracts to manage its interest rate exposures on certain liabilities. All derivative transactions are entered into to hedge interest and foreign currency exposures incorporated within the Group’s business. Accordingly, market risk in these derivatives is basi- cally offset by opposite movements in the value of hedged assets or liabilities. The Group does not hold or issue derivatives for trading purposes. Because the counterparties to these derivatives are limited to major international financial institutions, the Group does not anticipate any losses arising from credit risk.  Derivative transactions entered into by the Group have been made in accordance with internal policies which regulate the authorization and credit limit amount.
