As of September 30, 2023, cash and cash equivalents totaled $553.0 million and we had unused borrowing capacity of $1.49 billion under our $1.51 billion revolving credit facility, which expires in August 2024. We were in compliance with all covenants, including the leverage ratio (our one financial covenant) contained in our debt agreements and revolving credit facility. We believe, based on our current financial forecasts and trends, that we will remain compliant with all covenants for the foreseeable future.

Under our revolving credit facility we have the ability to draw loans based on two different interest rate indices, one of which was previously based on the London Interbank Offered Rate (LIBOR). During the second quarter of 2023, we amended our revolving credit facility to replace the LIBOR-based interest rate index, which was phased out, with a Secured Overnight Financing Rate (SOFR)-based interest rate index. The transition from LIBOR to SOFR did not have a material impact on the Company.
