As stated above, options on SPY are physically settled, and options on SPX are cash settled.
For example, if at expiration you owned 10 SPY call options with a strike price of 200 and the SPY closed at 201, you would have the right to purchase 1,000 shares of SPY at 200, which is $1 per share below the current price. Ten contracts times 100 shares times $1 per share means $1,000 of intrinsic value.
With index options, the exercise-settlement amount is equal to the difference between the exercise-settlement value and the strike price of the option, multiplied by $100. So for a similar example using SPX, let's assume that, at expiration, you owned one SPX call option with a strike price of 2,000 and the SPX settlement value (symbol: SET) is calculated to be 2,010. You would then have the right to a cash settlement for the difference between the settlement price and the strike (2,010 – 2,000), times a $100 multiplier, and times the number of contracts owned. In this case, 1 contract x 10 x $100, or $1,000 of intrinsic value.
European-style exercise simply means you are only able to exercise an option at expiration, while American-style exercise means you are able to exercise an option at any time during the contract's life. For an options seller, a European-style exercise option may be a good thing, because you know you won't be assigned a position before expiration.
SPY options are PM-settled, which means that exercise/assign - ment activity will result in the delivery of SPY shares. Only the option holder may initiate exercise/assignment activity, and it is done so at their discretion. Traditional SPX options with third- Friday expirations are AM-settled. This means the cash settle- ment in exercise/assignment is based on a calculation using the opening sales price in the primary market of each component security in the S&P 500. SPX Weeklys options, which expire on Fridays (other than third Fridays) and on Wednesdays, are PM- settled. This means exercise/assignment is based on a calcula- tion using the closing sales price in the primary market of each component security in the S&P 500.
