​ On June 6, 2023, we entered into a Fourth Amended and Restated Credit Agreement (the "Fourth Amended Credit Agreement"). The Fourth Amended Credit Agreement is a syndicated loan agreement with Wells Fargo Bank, National Association and other parties. The Fourth Amended Credit Agreement amended and restated in its entirety our previously outstanding Third Amended and Restated Credit Agreement and all amendments thereto. The Fourth Amended Credit Agreement provides for a term loan of $150 million and a revolving credit commitment of up to an aggregate amount of $700 million, inclusive of sub-facilities for multicurrency borrowings, standby letters of credit and swingline loans. On June 6, 2028, all principal, interest and other amounts outstanding under the Fourth Amended Credit Agreement are payable in full. At any time prior to the maturity date, we may repay any amounts owing under all term loans and revolving credit loans in whole or in part, without premium or penalty. ​ Term loans made under the Fourth Amended Credit Agreement bear interest, at our election, at either (i) the Base Rate (as defined in the Fourth Amended Credit Agreement) plus the Applicable Margin (as defined in the Fourth Amended Credit Agreement) or, (ii) Adjusted Term SOFR (as defined in the Fourth Amended Credit Agreement) plus the Applicable Margin (as defined in the Fourth Amended Credit Agreement). Revolving credit loans bear interest, at our election, at either (a) the Base Rate plus the Applicable Margin, (b) Adjusted Term SOFR plus the Applicable Margin, (c) Adjusted Eurocurrency Rate plus the Applicable Margin and (d) Adjusted Daily Simple SONIA (as defined in the Fourth Amended Credit Agreement) plus the Applicable Margin. Swingline loans bear interest at the Base Rate plus the Applicable Margin. Interest on each loan featuring the Base Rate and each Daily Simple SONIA Loan is due and payable on the last business day of each calendar month; interest on each loan featuring the Eurocurrency Rate and each Term SOFR Loan is due and payable on the last day of each interest period applicable thereto, and if such interest period extends over three months, at the end of each three-month interval during such interest period. ​ The Fourth Amended Credit Agreement is collateralized by substantially all our assets. The Fourth Amended Credit Agreement contains affirmative and negative covenants, representations and warranties, events of default and other terms customary for loans of this nature. In particular, the Fourth Amended Credit Agreement requires that we maintain certain financial covenants, as follows:
​ | ​ | ​ | ​ | ​
​ |  | Covenant Requirement | ​
Consolidated Total Leverage Ratio (1) |  | ​ | 4.0 to 1.0 | ​
Consolidated Interest Coverage Ratio (2) |  | ​ | 3.0 to 1.0 | ​
(1) | Maximum Consolidated Total Net Leverage Ratio (as defined in the Fourth Amended Credit Agreement) as of any fiscal quarter end.
(2) | Minimum ratio of Consolidated EBITDA (as defined in the Fourth Amended Credit Agreement and adjusted for certain expenditures) to Consolidated Interest Expense (as defined in the Fourth Amended Credit Agreement) for any period of four consecutive fiscal quarters.
​ We believe we were in compliance with all covenants set forth in the Fourth Amended Credit Agreement as of June 30, 2023. As of June 30, 2023, we had outstanding borrowings of $340.0 million and issued letter of credit guarantees of $3.2 million under the Fourth Amended Credit Agreement, with additional available borrowings of approximately $507 million, based on the maximum net leverage ratio and the aggregate revolving credit commitment pursuant to the Fourth Amended Credit Agreement. Our interest rate as of June 30, 2023 was a fixed rate of 2.64% with respect to $75 million of the principal amount, as a result of an interest rate swap (see Note 9), and a variable floating rate of 6.15% with respect to $265.0 million of the principal amount. Our interest rate as of December 31, 2022 was a fixed rate of 2.71% on $75 million as a result of an interest rate swap and a variable floating rate of 5.38% on $123.2 million. The foregoing fixed rates do not reflect potential future changes in the applicable margin. Future minimum principal payments on our long-term debt, as of June 30, 2023, were as follows (in thousands): ​
​ | ​ | ​ | ​
Years Ending | ​ | Future Minimum
December 31, |  | Principal Payments
Remaining 2023 |  | $ | 1,875
2024 | ​ | ​ | 3,750
