Term used to describe a contract that is ended because of the obligation of delivery.

This can happen because a bond is redeemed before maturity, a call or put option is exercised, or delivery is required on a short position held in a security. For example, if an investor has written a call option and the holder decides to exercise it, the option is referred to as "called away." At this time the writer must fulfill his/her contractual obligation, potentially missing the opportunity for further gains in the underlying asset.
