In the case of a European option, the option cannot be exercised before the expiry date, so it is possible for the time value to be negative; for an American option if the time value is ever negative, you exercise it ignoring special circumstances such as the security going ex dividend : this yields a boundary condition. Moneyness terms[ edit ] At the money[ edit ] An option is at the money ATM if the strike price is the same as the current spot price of the underlying security.
