The Credit Facility matures in June 2023. We may request two one of new lenders. At our option, borrowings under the Credit Facility bear interest at a Base Rate, or a Eurodollar Rate, plus an applicable margin based on our Debt Ratings (all as defined in the Credit Facility agreement). The Credit Facility is subject to facility fees based on applicable rates defined in the Credit Facility agreement and the aggregate commitment, regardless of usage. Availability under our Credit Facility totaled $1,526.6 million and $1,696.9 million as of March 31, 2020 and December 31, 2019, respectively. The Credit Facility can be used for working capital, capital expenditures, acquisitions, letters of credit and other general corporate purposes. The Credit Facility agreement requires us to comply with financial and other covenants. We may pay dividends and repurchase common stock if we are in compliance with these covenants. As of March 31, 2020 and December 31, 2019, we had $354.4 million and $184.4 million of borrowings under our Credit Facility, respectively. We had $352.3 million and $351.4 million of letters of credit outstanding under our Credit Facility as of March 31, 2020 and December 31, 2019, respectively. As of April 30, 2020, we had $189.4 million of borrowings under our Credit Facility. We also have an Uncommitted Credit Facility, which bears interest at LIBOR, plus an applicable margin and is subject to facility fees defined in the agreement, regardless of usage. We can use borrowings under the Uncommitted Credit Facility for working capital and other general corporate purposes. The agreement governing our Uncommitted Credit Facility requires us to comply with certain covenants. The Uncommitted Credit Facility may be terminated by either party at any time. We had $40.0 million of borrowings and $11.6 million of borrowings outstanding under our Uncommitted Credit Facility as of March 31, 2020 and December 31, 2019, respectively. As of April 30, 2020, we had $100.0 million of borrowings outstanding under our Uncommitted Credit Facility. Senior Notes and Debentures In February 2020, we issued $600.0 million of 2.300% senior notes due 2030 (the 2.300% Notes) and $400.0 million of 3.050% senior notes due 2050 (the 3.050% Notes). We used the net proceeds from the 2.300% Notes and 3.050% Notes to repay $850.0 million of 5.000% senior notes that matured in March 2020. The remaining proceeds were used to repay amounts outstanding under our unsecured credit facilities as well as for general corporate purposes. In August 2019, we issued $900.0 million of 2.500% senior notes due 2024 (the 2.500% Notes). We used the net proceeds from the 2.500% Notes to repay $650.0 million of 5.500% senior notes that matured in September 2019. The remaining proceeds were used to repay amounts outstanding under our unsecured credit facilities as well as for general corporate purposes. Our senior notes and debentures are general unsecured obligations. Interest is payable semi-annually. Interest Rate Swap and Lock Agreements Our ability to obtain financing through the capital markets is a key component of our financial strategy. Historically, we have managed risk associated with executing this strategy, particularly as it relates to fluctuations in interest rates, by using a combination of fixed and floating rate debt. From time to time, we also have entered into interest rate swap and lock agreements to manage risk associated with interest rates, either to effectively convert specific fixed rate debt to a floating rate (fair value hedges), or to lock interest rates in anticipation of future debt issuances (cash flow hedges). Fair Value Hedges During the second half of 2013, we entered into various interest rate swap agreements relative to our 4.750% fixed rate senior notes due in May 2023. The goal was to reduce overall borrowing costs and rebalance our debt portfolio's ratio of fixed-to-floating interest rates. As of March 31, 2020, these swap agreements had a total notional value of $300.0 million and mature in May 2023, which is identical to the maturity of the hedged senior notes. We pay interest at floating rates based on changes in LIBOR and receive interest at a fixed rate of 4.750%. These transactions were designated as fair value hedges because the swaps hedge against the changes in fair value of the fixed rate senior notes resulting from changes in interest rates. As of March 31, 2020 and December 31, 2019, the interest rate swap agreements are reflected at their fair value of $21.0 million and $10.7 million, respectively, and are included in other assets in our consolidated balance sheet. To the extent they are effective, these interest rate swap agreements are included as an adjustment to long-term debt in our consolidated balance sheets. We recognized net interest income of $0.7 million and $0.1 million during the three months ended March 31, 2020 and 2019, respectively, related to net settlements for these interest rate swap agreements, which is included as an offset to interest expense in our consolidated statements of income. For the three months ended March 31, 2020 and 2019, we recognized losses of $9.7 million and $3.4 million, respectively, on the change in fair value of the hedged senior notes attributable to changes in the benchmark interest rate, with offsetting gains of $10.3 million and $3.4 million, respectively, on the related interest rate swaps. The difference of these fair value changes for the three months ended March 31, 2020 was recorded directly in earnings as an adjustment to interest expense in our consolidated statements of income. For further detail regarding the effect of our fair value hedging on interest expense, refer to Note 11, Financial Instruments , of the notes to our unaudited consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q. Cash Flow Hedges As of March 31, 2020 and December 31, 2019, our interest rate lock agreements had an aggregate notional value of $200.0 million and $575.0 million, respectively, with fixed interest rates ranging from 0.784% to 2.374% and 1.330% to 3.000%, respectively. We entered into these transactions to manage exposure to fluctuations in interest rates in anticipation of planned future issuances of senior notes in 2020 and 2021. Upon the expected issuance of senior notes, we terminate the interest rate locks and settle with our counterparties. These transactions were accounted for as cash flow hedges. The fair value of our interest rate locks was determined using standard valuation models with assumptions about interest rates being based on those observed in underlying markets (Level 2 in the fair value hierarchy). The aggregate fair values of the outstanding interest rate locks as of March 31, 2020 were liabilities of $11.0 million, which were recorded in other long-term liabilities in our consolidated balance sheet. As of December 31, 2019, the aggregate fair values of the outstanding interest rate locks were assets of $3.6 million, which were recorded in prepaid expenses and other current assets in our consolidated balance sheet and liabilities of $15.7 million, which were recorded in other accrued liabilities and other long-term liabilities in our consolidated balance sheet. Total unrealized loss recognized in other comprehensive income for interest rate locks was $22.2 million and $11.3 million for the three months ended March 31, 2020 and 2019, respectively. As of March 31, 2020 and December 31, 2019, our previously terminated interest rate locks were recorded as components of accumulated other comprehensive loss, net of tax of $26.9 million and $4.7 million, respectively. The amortization of the terminated interest rate locks is recorded as an adjustment to interest expense over the life of the issued debt using the effective interest method. Over the next 12 months, we expect to amortize approximately $4.5 million from accumulated other comprehensive loss to interest expense as a yield adjustment of our senior notes . For further detail regarding the effect of our cash flow hedging on interest expense, refer to Note 11, Financial Instruments , of the notes to our unaudited consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q. Derivative Contracts Contemporaneously with the issuance of our 2.300% Notes in February 2020, we amended interest rate lock agreements with a notional value of $550.0 million, extending the mandatory maturity date from 2020 to 2030 and dedesignated them as cash flow hedges (the 2020 Extended Interest Rate Locks). Contemporaneously with the issuance of our 2.500% Notes in August 2019, we amended interest rate lock agreements with a notional value of $375.0 million, extending the mandatory maturity date from 2019 to 2024 and dedesignated them as cash flow hedges (collectively with the 2020 Extended Interest Rate Locks referred to as the Extended Interest Rate Locks). There was no ineffectiveness recognized in the termination of these cash flow hedges. In addition, we entered into offsetting interest rate swaps to offset future exposures to fair value fluctuations of the Extended Interest Rate Locks (the Offsetting Interest Rate Swaps). The fair value of these free-standing derivatives was determined using standard valuation models with assumptions about interest rates being based on those observed in underlying markets (Level 2 in the fair value hierarchy). As of March 31, 2020 and December 31, 2019, the fair value of the Extended Interest Rate Locks was a liability of $112.6 million and $22.2 million, respectively, which was included in other long-term liabilities in our consolidated balance sheets, and the fair value of the Offsetting Interest Rate Swaps was an asset of $61.6 million and $2.9 million, respectively, and was included in other assets in our consolidated balance sheets. For the three months ended March 31, 2020, we recognized a loss of $61.3 million on the change in fair value of the Extended Interest Rate Locks, with an offsetting gain of $58.7 million on the Offsetting Interest Rate Swaps. The change in fair value was recorded directly in earnings as an adjustment to interest expense in our consolidated statements of income. Tax-Exempt Financings As of March 31, 2020 and December 31, 2019, we had $1,060.1 million and $1,116.2 million of certain variable rate tax-exempt financings outstanding, respectively, with maturities ranging from 2020 to 2049. During the second quarter of 2019, we refinanced $35.0 million of tax-exempt financings and issued $30.0 million of new tax-exempt financings. In addition, we issued $50.0 million of tax-exempt financings during the fourth quarter of 2019. All of our tax-exempt financings are remarketed either quarterly or semi-annually by remarketing agents to effectively maintain a variable yield. The holders of the bonds can put them back to the remarketing agents at the end of each interest period. If the remarketing agent is unable to remarket our bonds, the remarketing agent can put the bonds to us. In the event of a failed remarketing, we currently have availability under our $2.25 billion unsecured revolving credit facility to fund these bonds until they are remarketed successfully. Accordingly, we have classified these borrowings as long-term in our consolidated balance sheets as of March 31, 2020 and December 31, 2019. As of March 31, 2020, we elected not to remarket and, instead, acquired $25.0 million of tax-exempt financings as a result of the rates available at the time. We intend to remarket these bonds when we believe the rates available are acceptable. Our investment in these bonds was recorded in prepaid expenses and other current assets in our consolidated balance sheet as of March 31, 2020. Finance Leases We had finance lease liabilities of $117.5 million and $119.3 million as of March 31, 2020 and December 31, 2019, respectively, with maturities ranging from 2020 to 2049. |
