Derivative, description of terms		During the six months ended June 30, 2022, we monetized our $500.0 million notional amount swaption for $13.7 million, and recognized a gain of $8.0 million, net of transaction costs.	We receive a cash settlement in the future if the prevailing interest rate is higher than the 1.68% five-year swap strike price. The amount of future cash settlement is capped if the prevailing interest rate exceeds 2.78%. Alternatively, if interest rates were to decrease below the specified strike price, we would not receive a cash settlement, nor would we have any requirement to make a payment.
