Line of Credit
We have a $20.0 million revolving line of credit with a lender that matures in November 2025. In January 2022, we executed the second loan modification agreement to increase the aggregate amount of funds our foreign subsidiaries are allowed to maintain outside of the United States. We were in compliance with all covenants as of June 30, 2022. As of June 30, 2022, we had no outstanding borrowings under this revolving line of credit, and we had outstanding letters of credit totaling $11.0 million in connection with securing our leased office space.
