The Term Loan Credit Agreement provides for a senior unsecured $2.0 billion term loan facility, and the Unsecured Revolving Credit Agreement provides for a senior unsecured $3.0 billion revolving credit facility. Borrowings under the term loan facility were made in U.S. dollars and borrowings under the revolving credit facility are available to be made in U.S. dollars, euros, sterling, Canadian dollars and, subject to certain conditions, certain other currencies at our option. Borrowings in U.S. dollars and certain other LIBOR quoted currencies will bear interest, at our option, at a rate equal to either (1) the rate (adjusted for any statutory reserve requirements for eurocurrency liabilities) for eurodollar deposits in the London interbank market, (2) a floating rate of interest set forth on the applicable LIBOR screen page designated by Bank of America or (3) the highest of (a) the federal funds effective rate plus 0.5% , (b) the rate of interest as publicly announced by Bank of America as its "prime rate" or (c) LIBOR plus 1.0% , in each case, plus an applicable margin. As of March 31, 2020 , the interest rates on the term loan facility and the revolving credit facility were 2.36% and 2.02% , respectively. In addition, we are required to pay a quarterly commitment fee with respect to the unused portion of the revolving credit facility at an applicable rate per annum ranging from 0.125% to 0.300% depending on our credit rating. Beginning on December 31, 2022, and at the end of each quarter thereafter, the term loan facility must be repaid in quarterly installments in the amount of 2.50% of original principal through the maturity date with the remaining principal balance due upon maturity in September 2024 . The revolving credit facility also matures in September 2024 . We may issue standby letters of credit of up to $250 million in the aggregate under the revolving credit facility. Outstanding letters of credit under the revolving credit facility reduce the amount of borrowings available to us. The total available commitments under the revolving credit facility at March 31, 2020 were $1.6 billion . Senior Unsecured Notes We have $3.0 billion in aggregate principal amount of senior unsecured notes, consisting of the following: (i) $1.0 billion aggregate principal amount of 2.650% senior notes due 2025; (ii) $1.25 billion aggregate principal amount of 3.200% senior notes due 2029; and (iii) $750 million aggregate principal amount of 4.150% senior notes due 2049. Interest on the senior notes is payable semi-annually in arrears on each February 15 and August 15. Each series of the senior notes is redeemable, at our option, in whole or in part, at any time and from time-to-time at the redemption prices set forth in the related indenture. We have an additional $3.0 billion in aggregate principal amount of senior unsecured notes consisting of the following: (i) $750 million aggregate principal amount of 3.800% senior notes due 2021; (ii) $550 million aggregate principal amount of 3.750% senior notes due 2023; (iii) $550 million aggregate principal amount of 4.000% senior notes due 2023; (iv) $750 million aggregate principal amount of 4.800% senior notes due 2026; and (v) $450 million aggregate principal amount of 4.450% senior notes due 2028.

For the 3.750% senior notes due 2023, the 4.000% senior notes due 2023 and the 4.450% senior notes due 2028, interest is payable semi-annually each June 1 and December 1. The difference between the fair value and face value of these senior notes at the date the Merger was consummated is recognized over the terms of the respective notes as a reduction of interest expense. The amortization of this fair value adjustment was $9.0 million for the three months ended March 31, 2020 . As of March 31, 2020 , our senior notes had a total carrying amount of $6.2 billion and an estimated fair value of $6.2 billion . The estimated fair value of our senior notes was based on quoted market prices in an active market and is considered to be a Level 1 measurement of the valuation hierarchy. The fair value of other long-term debt approximated its carrying amount at March 31, 2020 . Compliance with Covenants The senior unsecured term loan and revolving credit facility contain customary conditions to funding, affirmative covenants, negative covenants, financial covenants and events of default. As of March 31, 2020 , financial covenants under the term loan facility required a leverage ratio of 3.50 to 1.00 and an interest coverage ratio of 3.00 to 1.00. We were in compliance with all applicable covenants as of March 31, 2020 . Settlement Lines of Credit In various markets where we do business, we have specialized lines of credit, which are restricted for use in funding settlement. The settlement lines of credit generally have variable interest rates, are subject to annual review and are denominated in local currency but may, in some cases, facilitate borrowings in multiple currencies. For certain of our lines of credit, the available credit is increased by the amount of cash we have on deposit in specific accounts with the lender. Accordingly, the amount of the outstanding lines of credit may exceed the stated credit limit. As of March 31, 2020 and December 31, 2019 , a total of $58.0 million and $74.5 million , respectively, of cash on deposit was used to determine the available credit. As of March 31, 2020 and December 31, 2019 we had $375.2 million and $463.2 million , respectively, outstanding under these lines of credit with additional capacity to fund settlement of $1,092.1 million as of March 31, 2020 . During the three months ended March 31, 2020 , the maximum and average outstanding balances under these lines of credit were $679.0 million and $376.4 million , respectively. The weighted-average interest rate on these borrowings was 1.99% and 3.16% at March 31, 2020 and December 31, 2019 , respectively. Derivative Agreements We have interest rate swap agreements with financial institutions to hedge changes in cash flows attributable to interest rate risk on a portion of our variable-rate debt instruments. Net amounts to be received or paid under the swap agreements are reflected as adjustments to interest expense. Since we have designated the interest rate swap agreements as portfolio cash flow hedges, unrealized gains or losses resulting from adjusting the swaps to fair value are recorded as components of other comprehensive income (loss). The fair values of our interest rate swaps were determined based on the present value of the estimated future net cash flows using implied rates in the applicable yield curve as of the valuation date. These derivative instruments were classified within Level 2 of the valuation hierarchy. The table below presents information about our derivative financial instruments, designated as cash flow hedges, included in the consolidated balance sheets: Fair Values Derivative Financial Instruments Balance Sheet Location Weighted-Average Fixed Rate of Interest at March 31, 2020 Range of Maturity Dates at March 31, 2020 March 31, 2020 December 31, 2019 (in thousands) Interest rate swaps (Notional of $250 million at December 31, 2019) Prepaid expenses and other current assets NA NA $ — $ 472 Interest rate swaps (Notional of $550 million at March 31, 2020) Accounts payable and accrued liabilities 1.65% July 31, 2020 - March 31, 2021 $ 5,365 $ — Interest rate swaps (Notional of $1.25 billion at March 31, 2020 and $1.55 billion at December 31, 2019) Other noncurrent liabilities 2.73% December 31, 2022 $ 84,361 $ 45,604 NA = not applicable.
