Fair Value of Financial Instruments, Policy

The Company uses the market approach to measure fair value for its marketable securities, time deposits and derivative instruments. The Company’s interest rate swaps were primarily valued using the 3-month LIBOR rate. The Company’s put option contracts, as well as its foreign exchange forward contracts, are primarily valued using the appropriate foreign exchange spot rates. The Company’s precious metal forward contracts are primarily valued using the relevant precious metal spot rate.
