(a) The Secured Revolving Credit Facility (Secured Facility) provided working capital and letter of credit capacity of $250.0 million and was scheduled to mature in February 2024; however, the Secured Facility was terminated early in October 2022 in conjunction with the Company entering into the Senior Unsecured Revolving Credit Facility. We recorded a loss on extinguishment of debt of $0.5 million during the nine months ended June 30, 2023 due to write-off of debt issuance costs related to the early termination of the Secured Facility. As of September 30, 2022, no borrowings were outstanding and $5.5 million letters of credit were outstanding under the Secured Facility, resulting in a remaining capacity of $244.5 million.

(b) The Senior Unsecured Revolving Credit Facility was entered into on October 13, 2022. Refer to below for further discussion.
