[3] As of September 30, 2022, there were $2 million of letters of credit outstanding under our $250 million Revolving Credit Facility. The letters of credit are posted in lieu of cash to satisfy regulatory requirements in certain states in which we operate. The Credit Agreement contains covenants that limit or restrict our ability, including the ability of certain of our subsidiaries, to incur additional indebtedness, repurchase debt, incur liens, sell assets, make certain payments (including dividends) and enter into transactions with affiliates; therefore, from time to time, our ability to draw on the Revolving Credit Facility may be limited. As of September 30, 2022, the available borrowing capacity under the Revolving Credit Facility was limited by the applicable consolidated first lien leverage ratio contained in the Credit Agreement to $199 million.
