The Credit Agreement replaces our prior $250,000 revolving credit agreement originally entered into on January 4, 2016 (“Original Credit Agreement”). The Credit Agreement provides a subfacility of up to $10,000 for letters of credit and a subfacility of up to $10,000 for swing-line loans and also includes a $100,000 accordion feature that provides us with the ability to obtain up to $400,000 in the aggregate of revolving credit commitments and/or term loans upon satisfaction of certain conditions. The Credit Agreement matures on March 29, 2023 and the full balance of the revolving loans and all other obligations under the agreement must be paid at that time. In addition, we are required to prepay the revolving loan balance if at any time the aggregate principal amount outstanding under the Credit Agreement exceeds the aggregate commitments thereunder. The Credit Agreement is secured by substantially all of our existing and future property. The revolving loans under the Credit Agreement will be available for letters of credit, permitted acquisitions, working capital and general corporate purposes. We were in compliance with all financial and non-financial covenants under the Credit Agreement as of December 31, 2018.
