Only the quarterly options and futures are cash settled. The in the money options for the other 8 months settle into the underlying futures contract. From CMEGroup website: "Option exercise results in a position in the underlying cash-settled Futures contract. Options which are in-the-money on the last day of trading are automatically exercised. QUARTERLY OPTIONS are exercised into expiring cash-settled futures, which settle to the SOQ calculated the morning of the 3rd Friday of the contract month. SERIALS are exercised into underlying cash-settled futures at their closing price on 3:15 p.m. on the 3rd Friday of the contract month"
