• To implement the right of the holder of an option to buy (in the case of a call) or sell (in the case of a put) the underlying security.
• To invoke the right to buy or sell granted under terms of a listed options contract.
• Is the action taken by the holder of an option or convertible security to convert his derivative position into the underlying security, commodity or futures. In the case of the option the exercise of a call would give the owner of the call the underlying instrument or cash settlement adjustment. In the case of a convertible bond, the owner of the bond terminates that contractual relationship in exchange for shares in the corporation. The owner of the option is the only one that exercises. However, there are mandatory exercises for expiring options that are in-the-money by more than the stipulated threshold amount. Also, there may be built-in event options that take priority over the owner of the securities right to exercise. Nevertheless, this nesting of options still defers to rules that establish which party holds, which options.

| ||At the money: Is an option which has an Exercise or strike price that is the same as the underlying instrument at current market valuations.An option is at-the-money if the strike price of the option is equal to the market price of the underlying security.

| ||Automatic exercise: Occurs after an option expires. Each exchange and its clearing house has rules which govern this Exercise. There are minimum in-the-money requirements. A holder of an option must inform the clearing house not to automatically exercise an option. These instructions not to exercise may be due to relatively high transaction costs, increases in position limits, or unacceptable alterations in position profiles. Also, after hours trading indications may suggest dramatically different prices than those used to determine the automatic exercise in-the-money amounts.|
