Senior Notes

In April 2018, we issued $1.5 billion aggregate principal amount of 5.125% Senior Notes due 2026 (the "2026 Senior Notes"), and incurred $21 million of debt issuance costs. Interest on the 2026 Senior Notes is payable semi-annually in arrears on May 1 and November 1 of each year, beginning November 2018. We used a portion of the net proceeds from the issuance of the 2026 Senior Notes, together with borrowings under our senior secured revolving credit facility (the "Revolving Credit Facility") and available cash, to repurchase 16.5 million shares of our common stock from HNA for $1,171 million and repay $500 million outstanding under our senior secured term loan facility (the "Term Loans"). See "Senior Secured Credit Facilities" below for additional information.

In March 2017, we used the proceeds from issuances of the 4.625% Senior Notes due 2025 (the "2025 Senior Notes") and the 4.875% Senior Notes due 2027 (the "2027 Senior Notes"), to redeem in full $1.5 billion of Senior Notes due 2021 (the "2021 Senior Notes"). In connection with the repayment, we paid a redemption premium of $42 million and accelerated the recognition of $18 million of unamortized deferred financing costs, which were included in loss on debt extinguishment in our consolidated statement of operations for the year ended December 31, 2017.

The 4.250% Senior Notes due 2024 (the "2024 Senior Notes"), the 2025 Senior Notes, the 2026 Senior Notes and the 2027 Senior Notes are guaranteed on a senior unsecured basis by the Parent and substantially all of its direct and indirect wholly owned domestic subsidiaries. See Note 23: "Condensed Consolidating Guarantor Financial Information" for additional information.

Senior Secured Credit Facilities

Our senior secured credit facility consists of a $1.0 billion Revolving Credit Facility and the Term Loans. The obligations of our senior secured credit facility are unconditionally and irrevocably guaranteed by the Parent and substantially all of its direct and indirect wholly owned domestic subsidiaries. During the year ended December 31, 2018, we borrowed $150 million under the Revolving Credit Facility, and all amounts borrowed were repaid in the same period. Subsequent to December 31, 2018, we drew a net $100 million under the Revolving Credit Facility.

In December 2018, we repaid an additional $300 million outstanding under our Term Loans, and as a result of the repayments made during the year ended December 31, 2018, we accelerated the recognition of $8 million of unamortized deferred financing costs and discount, which were included in other non-operating income, net in our consolidated statement of operations. Additionally, the interest rate on the remaining balance of the Term Loans was reduced by 25 basis points to LIBOR plus 175 basis points.

As of December 31, 2018, we had $63 million of letters of credit outstanding under our Revolving Credit Facility and a borrowing capacity of $937 million. We are required to pay a commitment fee of 0.125 percent per annum under the Revolving Credit Facility in respect of the unused commitments thereunder.
