The Credit Agreement is secured by substantially all of our existing and future property and material domestic subsidiaries. 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. The Credit Agreement matures on January 4, 2021 and the full balance of the revolving loans and all other obligations under the agreement must be paid at that time. The revolving loans under the Credit Agreement will be available for letters of credit, working capital and general corporate purposes. We were in compliance with all covenants under the Credit Agreement as of September 30, 2017.
