Every stock option has four predetermined specifications:
-
The underlying asset.
-
The type of stock option (call or put).
-
The exercise price (or the strike price).
-
The expiration date (or exercise date).
These four specification are listed in David’s letter from his father:
-
The underlying asset is the asset received — if, and when, the option is exercised. In this case, the underlying asset is an ounce of gold.
-
The type of option: The type of option in the letter is a call option.
-
The exercise price is the price paid for the underlying asset if the option is exercised. David must pay $400 for an ounce of gold.
-
The expiration date is the date on which the option can be exercised. If David does not exercise his option on March 31, 2009, then the option becomes worthless.
