⁽¹⁾Refer to Note 8. Leases

⁽²⁾ We offered an additional issuance of these notes on September 6, 2019.

Accrued interest associated with our outstanding debt obligations was $20.7 million and $19.0 million as of December 31, 2020 and 2019, respectively, and included in “Accounts payable and accrued liabilities” within our accompanying consolidated balance sheets. Interest expense associated with our finance lease and outstanding debt obligations, including amortization of debt issuance costs and original discounts, was $138.3 million, $125.7 million and $128.2 million for the years ended December 31, 2020, 2019 and 2018, respectively.

Senior Notes

On May 8, 2020, we completed an issuance of $500.0 million aggregate principal amount of 3.625% senior notes due 2050 (the "2050 notes"). The 2050 notes mature on May 15, 2050 and accrue interest at a fixed rate of 3.625% per annum. Interest is payable semiannually on the 2050 notes on May 15th and November 15th of each year, beginning on November 15, 2020. The 2050 notes were issued at a discount of $5.2 million, and we incurred debt issuance costs of $5.7 million. The original issue discount and debt issuance costs were included in "Long-term debt" in our accompanying consolidated balance sheets, and these costs will be amortized to "Interest expense" in our accompanying consolidated statements of operations over the life of the 2050 notes. The net proceeds from the issuance of the 2050 notes were utilized to partially repay the committed senior unsecured Syndicated Revolving Credit Facility (the "Credit Facility") and for general corporate purposes. The indenture governing the 2050 notes restricts our ability to, among other things, create certain liens, enter into sale/leaseback transactions and consolidate with, sell, lease, convey or otherwise transfer all or substantially all of our assets, or merge with or into, any other person or entity. As of December 31, 2020 and December 31, 2019, we had senior notes with an aggregate principal amount of $3,150.0 million and $2,650.0 million outstanding, respectively, and were in compliance with our financial and other debt covenants.

Syndicated Revolving Credit Facility

We have a Credit Facility with a borrowing capacity of $1,000.0 million with Bank of America N.A., HSBC Bank USA, N.A., JP Morgan Chase Bank, N.A., Wells Fargo Bank, National Association, Citibank, N.A., Credit Suisse AG, Cayman Islands Branch, Morgan Stanley Bank, N.A., TD Bank, N.A., and the Northern Trust Company. Interest on borrowings under the Credit Facility is payable at an interest rate of LIBOR plus 1.0% to 1.625%, depending upon the public debt rating. A commitment fee on any unused balance is payable periodically and may range from 8.0 to 20.0 basis points based upon the public debt rating. The Credit Facility also contains certain financial and other covenants that, among other things, impose certain restrictions on indebtedness, liens, investments, and capital expenditures. These covenants place restrictions on mergers, asset sales, sale/leaseback transactions, and certain transactions with affiliates. The financial covenants require that, at the end of any fiscal quarter, we have a consolidated funded debt leverage ratio of less than 3.5 to 1.0. At our election, the maximum consolidated funded debt leverage ratio could be permitted to increase one time each to 4.0 to 1.0 and 4.25 to 1.0. The Credit Facility may be used for general corporate purposes, including working capital needs and capital expenditures, acquisitions, dividends and the share repurchase program (the "Repurchase Program"). As of December 31, 2020, we were in compliance with all financial and other debt covenants under the Credit Facility. As of December 31, 2020 and 2019, the available capacity under the Credit Facility was $944.6 million and $500.2 million, net of the letters of credit of $5.4 million and $4.8 million, respectively. Subsequent to December 31, 2020, we had no borrowings and made repayments of $50.0 million under the Credit Facility.
