Definition
For a call option: in-the-money (ITM) when the underlying price exceeds the strike; at-the-money (ATM) when they are equal; out-of-the-money (OTM) when the underlying is below the strike. For a put option, the relationship is reversed: ITM when the underlying is below the strike, OTM when above. Only ITM options have intrinsic value; OTM options have only time value. An ITM call with a strike of $50 on a stock trading at $58 has $8.00 of intrinsic value; the remaining premium above $8.00 is time value. At expiry, a call is exercised only if it is ITM; if OTM at expiry it expires worthless and the buyer loses the full premium paid. Moneyness directly affects the delta of an option: deep ITM options have a delta approaching 1.0 (call) or -1.0 (put), ATM options have a delta near 0.5 (call) or -0.5 (put), and deep OTM options have a delta approaching zero.
