intrinsic value if the price is equal to or below DM2.50 at that time. Changes in the exchange rate between German marks and British pounds may result from changes in the value of German marks relative to other currencies generally, from changes in the value of the British pound. or from a combination of the two. In any case, the intrinsic value of the option will be deter- mined by the value of the British pound relative to the German mark. and not to the U.S. dollar or any other currency. However, as is noted in the following sec- tion, fluctuations in the value of the trading currency relative to other currencies may significantly affect in- vestors who intend to convert their gains or losses into one of those other currencies.

SPECIAL FEATURES OF DOLLAR-DENOMINATED FOREIGN CURRENCY OPTIONS The amount of the foreign currency underlying each foreign currency option (i.e., the unit of trading) is specified by the options market on which the option is traded. Exercise prices for currently available dollar-denomi- nated options on foreign currencies other than the Japanese yen are stated in U.S. cents per unit of for- eign currency. Exercise prices for dollar-denominated Japanese yen options are expressed in hundredths of U.S. cents per unit. In order to determine the total exercise price per contract, it is necessary to multiply the stated exercise price by the unit of trading of the particular option. EXAMPLE: A dollar-denominated put covering 31.250 British pounds with an exercise price of 130 would entitle the holder to sell the underlying pounds for an aggregate exercise price of $40,625 ($1.30 mul- tiplied by 31,250). EXAMPLE: A dollar-denominated call covering
