During the nine months ended September 30, 2018, we settled the remaining forward exchange contracts upon expiration.

On the acquisition date, the aggregate fair value of the interest rate swaps represented an asset of $14 million. In July and August 2018, we received aggregate cash proceeds of $18 million in connection with the settlement and termination of the interest rate swaps. In the three and nine months ended September 30, 2018, we recognized a loss of $1 million and a gain of $4 million, respectively, recorded in other, net, associated the interest rate swaps. Currency swaps—In connection with the Songa acquisition, we acquired currency swaps, which were previously designated as a cash flow hedge, to reduce the variability of cash interest payments and the final cash principal payment associated with the Bond Loans resulting from the changes in the U.S. dollar to Norwegian krone exchange rate. On the acquisition date, the aggregate fair value of the currency swaps represented a liability of $81 million. In February 2018, we made an aggregate cash payment of $92 million in connection with the settlement and termination of the currency swaps. In the nine months ended September 30, 2018, we recognized a loss of $11 million, recorded in other, net., associated with the currency swaps.
