On March 16, 2022, the Company completed its offering and sale of $300.0 million in aggregate principal amount of 7.625 percent Senior Notes due 2030 (the "2030 Notes"). The 2030 Notes accrue interest at the rate of 7.625 percent per annum, with interest payable in cash semi-annually in arrears on March 15 and September 15, commencing September 15, 2022. The 2030 Notes will mature on March 15, 2030. The 2030 Notes are senior unsecured indebtedness of the Company, ranking equally in right of payment with all its existing and future senior unsecured indebtedness and senior to its future subordinated indebtedness. The Company used the net proceeds from the issuance of the 2030 Notes to repay, in April 2022, in full $300.0 million in principal of its 4.45 percent senior unsecured notes due March 2023, including any interest and premium due thereon.

On March 26, 2021, the Company entered into a $300.0 million secured revolving credit facility (the "Credit Facility"). The Credit Facility amended and restated the Company's previous revolving credit facility, dated March 31, 2017, which had been set to expire in March 2022. The Credit Facility extends the maturity to March 31, 2024. This was subject to a springing maturity of November 30, 2022. If, by November 30, 2022, the Company's $300.0 million 4.45 percent Senior Notes due in March 2023 were not redeemed, repurchased or refinanced with indebtedness having a maturity date of October 1, 2024 or later, all indebtedness under the Credit Facility would have been due. The springing maturity clause has been satisfied with the issuance of the 2030 Notes and subsequent payment in full of the 4.45 percent Senior Notes, as discussed above. The Credit Facility contains a revolving credit commitment amount of $300.0 million, subject to the Company's right, from time to time, to request an increase of the commitment to $500.0 million in the aggregate; and provides for the issuance of letters of credit subject to a $40.0 million sub-limit. The Company has the right to terminate or reduce the commitments under the Credit Facility, and, subject to certain lender approvals, to join subsidiaries as subsidiary borrowers.

On February 14, 2022, the Company entered into an amendment (the "Amendment") to its Credit Facility. The Amendment revised the interest coverage ratio covenant under the Credit Facility so the first test date was June 30, 2022, and required a minimum interest coverage ratio of 2.00 to 1.00 at June 30, 2022 (calculated for the two fiscal quarters then ended), 3.00 to 1.00 at September 30, 2022 (calculated for the three fiscal quarters then ended) and 3.50 to 1.00 at December 31, 2022 and thereafter (calculated for the four fiscal quarters then ended). The Amendment revised the restricted period under the Credit Facility, during which the Company was prohibited from incurring any secured debt other than purchase money financing for new equipment and was subject to additional restrictions on its ability to make dividends or distributions or to make certain investments. The restricted period expired on September 30, 2022.

Interest on the borrowings under the Credit Facility accrues at variable rates, based upon a "Eurocurrency Rate" or a defined "Base Rate". Both are determined based upon the credit rating of the Company's senior unsecured long-term debt (the "Debt Rating"). The applicable margin to be added to the Eurocurrency Rate ranges from 1.25 percent to 2.25 percent (2.25 percent as of March 31, 2023), and for Base Rate-determined loans, from 0.25 percent to 1.25 percent (1.25 percent as of March 31, 2023). The Company also pays a quarterly commitment fee ranging from 0.275 percent to 0.375 percent (0.375 percent as of March 31, 2023), determined based upon the Debt Rating, of the unused portion of the $300.0 million commitment under the Credit Facility. In addition, the Company must pay certain letter of credit fees, ranging from 1.25 percent to 2.25 percent (2.25 percent as of March 31, 2023), with respect to letters of credit issued under the Credit Facility. The Company has the right to voluntarily prepay and re-borrow loans and to terminate or reduce the commitments under the facility. As of March 31, 2023, the Company had $1.8 million of issued letters of credit under the Credit Facility and $108.6 million of short-term borrowings with the balance of $189.6 million available to the Company. As of March 31, 2023, the borrowing rate for the Credit Facility was 6.84 percent.

The Company is subject to certain financial and restrictive covenants under the Credit Facility, which, among other things, require the maintenance of a minimum interest coverage ratio. The interest coverage ratio is defined in the Credit Facility as, for any period, the ratio of consolidated earnings before interest, taxes, depreciation and amortization and non-cash net pension expense ("EBITDA") to consolidated interest expense for such period. The interest coverage covenant was waived until the quarter ended June 30, 2022 at which time it was required to be 2.00 to 1.00, then 3.00 to 1.00 at September 30, 2022 and then 3.50 to 1.00 at December 31, 2022 and thereafter. The Credit Facility also requires the Company to maintain a debt to capital ratio of less than 55 percent. The debt to capital ratio is defined in the Credit Facility as the ratio of consolidated indebtedness, as defined therein, to consolidated capitalization, as defined therein. In addition, the Company is also subject to an asset coverage ratio minimum of 1.10 to 1.00. The asset coverage ratio is defined in the Credit Facility as eligible receivables and inventory, as defined therein, to outstanding loans and obligations, as defined therein. As of March 31, 2023, the Company was in compliance with all of the covenants of the Credit Facility. The preceding Credit Facility discussions pertain to the terms in place as of the current quarter ended March 31, 2023, see Note 17. Subsequent Event for additional details.
