Long-term debt consisted of the following items as of December 31:
Maturities of long-term debt (excluding unamortized debt issuance costs) as of December 31, 2019 are as follows:
(1) The Company has entered into a senior secured revolving credit facility, as amended (the "revolving credit facility"), with The Bank of Nova Scotia, as the lead arranger and administrative agent and other lenders. The revolving credit facility matures on December 13, 2021. On June 3, 2019, the Company further amended its revolving credit facility to, among other things, allow the Company to designate certain of its subsidiaries as unrestricted subsidiaries and to include LIBOR replacement provisions. The borrowing base was reaffirmed at $1.4 billion, and the Company's elected commitment amount remained at $1.0 billion. On November 25, 2019, the borrowing base under the Company's revolving credit facility was reduced to $1.2 billion, and the Company's elected commitment remained at $1.0 billion.
As of December 31, 2019, $120.0 million was outstanding under the revolving credit facility and the total availability for future borrowings under this facility, after giving effect to an aggregate of $243.6 million of letters of credit, was $636.4 million. The Company's wholly-owned subsidiaries have guaranteed the obligations of the Company under the revolving credit facility.
At December 31, 2019, amounts borrowed under the credit facility bore interest at a weighted average rate of 3.30%.
The Company was in compliance with all covenants related to its outstanding indebtedness at December 31, 2019.

In July of 2019, the Company's Board of Directors authorized $100 million of cash to be used to repurchase its senior notes in the open market at discounted values to par. In December 2019, the Company's Board of Directors increased the authorized size of its senior note repurchase program to $200 million in total. During the year ended December 31, 2019, the Company used borrowings under its revolving credit facility to repurchase in the open market approximately $190.1 million aggregate principal amount of its outstanding Notes for $138.8 million in cash. This included approximately $20.5 million principal amount of the 2023 Notes, $46.6 million principal amount of the 2024 Notes, $70.5 million principal amount of the 2025 Notes, and $52.5 million principal amount of the 2026 Notes.
