Credit Agreement

On July 26, 2023, we entered into Amendment No. 4 to our Credit Agreement, which provides for a new $550.0 million Term Facility Two, the proceeds of which will be used, in part, to finance the acquisition of SPI, including the payment of related fees and expenses. The Term Facility Two availability period ends on October 25, 2024, if not drawn. Once drawn, Term Facility Two will mature on October 7, 2026 and will be subject to substantially the same scheduled percentage amortization payments as the Company’s existing term loan facility under the Credit Agreement. Borrowings of Term Facility Two bear interest at SOFR or the Base Rate (each as defined in Credit Agreement) plus an applicable rate ranging from 1.50% to 3.00% for SOFR-based loans and from 0.50% to 2.00% for Base Rate-based loans, depending upon the Company’s consolidated secured leverage ratio. The Company is required to pay a ticking fee on the undrawn Term Facility Two commitments at an annual rate equal to: (i) 0.175% for the first six-month period after the Amendment Effective Date, (ii) 0.200% for the next successive six-month period, and (iii) 0.250% for next successive three-month period.

Interest payable on borrowings under the Credit Agreement is based on an applicable margin rate plus, at our option, either:

​

The applicable margin rate is determined based on our Secured Leverage Ratio. In the case of base rate borrowings, the applicable margin rate ranges from 0.00 percent to 1.50 percent for Term Facility One and 0.50 percent to 2.00 percent for Term Facility Two and in the case of SOFR rate borrowings, the applicable margin ranges from 1.00 percent to 2.50 percent for Term Facility One and 1.50 percent to 3.00 percent for Term Facility Two. Borrowings under the Credit Agreement are prepayable at the Company’s option without premium or penalty. The Company is required to make prepayments with the net cash proceeds of certain asset sales and certain extraordinary receipts.  

​

Revolving Facility

​

The Company has outstanding standby letters of credit that secure our financial obligations related to our workers’ compensation, general insurance, and auto liability programs.  These standby letters of credit, as well as any outstanding amount borrowed under our revolving facility, reduce the availability under the revolving facility.  The following table summarizes our availability under the revolving facility, in thousands:

​

We are required to pay commitment fees to the Lenders in respect of any unutilized commitments.  The commitment fees range from 0.15 percent to 0.275 percent per annum, depending on our Secured Leverage Ratio.  We must also pay customary fees on outstanding letters of credit.

Covenant Compliance

The indentures governing our 3.625% Senior Notes and our 4.125% Senior Notes (together, our “Senior Notes”) contain restrictive covenants that, among other things, generally limit the ability of the Company and certain of its subsidiaries (subject to certain exceptions) to (i) create liens, (ii) pay dividends, acquire shares of capital stock and make payments on subordinated debt, (iii) place limitations on distributions from certain subsidiaries, (iv) issue or sell the capital stock of certain subsidiaries, (v) sell assets, (vi) enter into transactions with affiliates and (vii) effect mergers.  The indentures provide for customary events of default which include (subject in certain cases to customary grace and cure periods), among others: nonpayment of principal or interest; breach of covenants or other agreements in the indenture; defaults in failure to pay certain other indebtedness; and certain events of bankruptcy or insolvency. Generally, if an event of default occurs and is continuing under the indenture, the trustee or the holders of at least 30% in aggregate principal amount of each of our Senior Notes then outstanding may declare the principal of, premium, if any, and accrued interest on the Senior Notes subject to such declaration immediately due and payable. The Senior Notes and related guarantees have not been registered under the Securities Act of 1933, and we are not required to register either the Senior Notes or the guarantees in the future.
