Debt

3 Months Ended

Mar. 31, 2021

Debt outstanding consisted of amounts drawn on our revolving credit facility of $840,000 as of March 31, 2021 and December 31, 2020. As of March 31, 2021, the total availability under our revolving credit facility was $1,150,000. The facility includes an accordion feature allowing us, subject to lender consent, to increase the credit commitment to an aggregate amount not exceeding $1,425,000. The credit facility matures in March 2023. Our quarterly commitment fee ranges from 0.175% to 0.35% based on our leverage ratio. Amounts drawn under the credit facility had a weighted-average interest rate of 2.00% as of March 31, 2021 and 2.01% as of December 31, 2020. In July 2019, we executed an interest rate swap to convert $200,000 of the amount drawn under the credit facility to fixed rate debt. Further information can be found in Note 6.

Borrowings under the credit agreement are collateralized by substantially all of our personal and intangible property. The credit agreement governing our credit facility contains customary covenants regarding limits on levels of subsidiary indebtedness and capital expenditures, liens, investments, acquisitions, certain mergers, certain asset sales outside the ordinary course of business and change in control as defined in the agreement. The agreement also requires us to maintain certain financial ratios, including a maximum leverage ratio of 3.5 and a minimum ratio of consolidated earnings before interest and taxes to consolidated interest expense, as defined in the credit agreement, of 3.0. Additionally, the agreement contains customary representations and warranties and, as a condition to borrowing, requires that all such representations and warranties be true and correct in all material respects on the date of each borrowing, including representations as to no material adverse change in our business, assets, operations or financial condition.

There are currently no limitations on the amount of dividends and share repurchases under the terms of our credit agreement. However, if our leverage ratio, defined as total debt less unrestricted cash to EBITDA, should exceed 2.75 to 1, there would be an annual limitation on the amount of dividends and share repurchases.
