On September 2, 2021, we entered into a restatement agreement as part of a Fourth Amended and Restated $400.0 million Revolving Credit Facility and a €220.0 million Term Loan (collectively, the “Credit Facility ”) which matures September 6, 2026 and February 8, 2024, respectively.

Revolving Loans borrowings are available in U.S. Dollars, Euros, British Pound Sterling, and Canadian Dollars and the borrowing of Term Loans are available in Euros. The principal amount of the Term Loan amortizes in consecutive quarterly installments of principal, with each such quarterly installment to be in an amount equal to 1.25% of the Term Loan funded.

On May 9, 2022, we entered into an amendment to the Credit Agreement, which was further amended on March 30, 2023. The March 30, 2023 amendment to the Credit Agreement reduced the Revolving Credit Facility to $250.0 million and had us fully extinguish the €220.0 million Term Loan. The amendment: i) modifies the “leverage ratio” to be the ratio of consolidated senior secured debt to consolidated adjusted EBITDA ; ii) increases the maximum interest rate borrowing margin to be applied to the applicable index by 275 basis points; and iii) pledges as collateral substantially all domestic and Canadian assets to secure obligations owed under the Credit Agreement, as well as, on a second lien basis, the European assets that secure the AG Loan (as defined below). As amended, we are obligated to maintain a leverage ratio under 4.25 to 1.0 through the quarter ended December 31, 2024, stepping down to 4.0 to 1.0 at March 31, 2025, and 3.50 to 1.0 at March 31, 2026.

Borrowing rates for the Revolving Loans are determined at our option at the time of each borrowing. For all U.S. Dollar denominated Revolving Loan borrowings, the borrowing rate is either, (a) the bank’s base rate which is equal to the greater of i) the prime rate; ii) the overnight bank funding rate plus 50 basis points; or iii) the daily Simple Secured Overnight Financing Rate (“SOFR”) rate plus 100 basis points plus an applicable spread over either i), ii) or iii) ranging from 250 basis points to 400 basis points based on the Company’s leverage ratio; or (b) the daily Term SOFR-rate plus an applicable margin ranging from 350 basis points to 500 basis points based on the Company’s leverage ratio. For non-U.S. Dollar denominated borrowings, interest is based on the Euro-rate or EURIBOR-rate plus an applicable margin ranging from 350 basis points to 500 basis points based on the Company’s leverage ratio.

The Credit Agreement contains a number of customary covenants for financings of this type that, among other things, restrict our ability to dispose of or create liens on assets, incur additional indebtedness, limits certain intercompany financing arrangements, make acquisitions and engage in mergers or consolidations. The Credit Agreement also contains covenants requiring a minimum debt coverage ratio.

As of December 31, 2023, the leverage ratio and the debt service ratio, as calculated in accordance with the definition in our Credit Agreement, was 3.4x and 1.7, respectively. A breach of these requirements would give rise to certain remedies under the Revolving Credit Facility, among which is the termination of the agreement.

On March 30, 2023, we entered into a €250.0 million Term Loan with certain affiliates of Angelo, Gordon & Co., L.P. (“AG Loan”). The net proceeds from the AG Loan were used to extinguish the €220.0 million Term Loan, to repay a portion of outstanding revolving borrowings under the Revolving Credit Facility, for working capital and general corporate purposes and to pay estimated fees and expenses.

The AG Loan will mature on March 23, 2029. Interest on the AG Loan accrues at the rate of 11.25% per annum and is payable quarterly in arrears on March 31, June 30, September 30, and December 31 each year, commencing on June 30, 2023.

The AG Loan is prepayable, in whole or in part, at any time at the prepayable premium specified in the Term Loan Agreement. Prior to September 30, 2024, we may prepay some or all of the AG Loan at a "make-whole" premium as specified.

Under the terms of the AG Loan, we have pledged as collateral substantially all assets of our subsidiaries in Germany, Luxembourg, United Kingdom, Malta and Switzerland, as well as, on a second lien basis, the domestic and Canadian assets that secure the Revolving Credit Facility.

On October 25, 2021, we issued $500.0 million aggregate principal amount of 4.750% senior notes due 2029 (the “Notes”). The Notes are guaranteed on a senior unsecured basis, jointly and severally, by each of our existing and future domestic restricted subsidiaries that guarantees our obligations under the Credit Agreement, and/or certain other indebtedness (the “Guarantees”).

The Notes were issued pursuant to an indenture dated as of October 25, 2021 (the “Base Indenture”), as supplemented by the supplemental indenture dated as of October 25, 2021 (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”) among the Company, certain subsidiaries of the Company party thereto (the “Guarantors”) and Wilmington Trust, National Association, as trustee.

The net proceeds from the offering of the Notes, together with cash on hand, were used to pay the purchase price of the Jacob Holm acquisition, to repay certain indebtedness of Jacob Holm, to repay outstanding revolving borrowings under the Revolving Credit Facility, and to pay estimated fees and expenses.

The Notes will mature on November 15, 2029. Interest on the Notes accrues at the rate of 4.750% per annum and is payable semi-annually in arrears on May 15 and November 15 of each year, commencing on May 15, 2022.

The Notes are redeemable, in whole or in part, at any time at the redemption prices specified in the underlying indenture. Prior to November 15, 2024, we may redeem some or all of the Notes at a "make-whole" premium as specified.

The Notes contain various covenants customary to indebtedness of this nature, including limitations on i) the amount of indebtedness that may be incurred; ii) certain restricted payments including common stock dividends; iii) distributions from certain subsidiaries; iv) sales of assets; v) transactions amongst subsidiaries; and vi) incurrence of liens on assets. In addition, the Notes contain cross default provisions that could result in all such notes becoming due and payable in the event of a failure to repay debt outstanding under the Credit Agreement at maturity or a default under the Credit Agreement that accelerates the debt outstanding thereunder. As of December 31, 2023, we met all of the requirements of our debt covenants.

Glatfelter Gernsbach GmbH (“Gernsbach”), a wholly-owned subsidiary of ours, entered into a series of borrowing agreements with IKB Deutsche Industriebank AG, Düsseldorf (“IKB”). Each of the borrowings require quarterly repayments of principal and interest and provide for representations, warranties and covenants customary for financings of these types. The financial covenants contained in each of the IKB loans are calculated by reference to our Credit Agreement. These borrowings were fully extinguished on March 14, 2023.

In 2021, Gernsbach also entered into two fixed-rate non-amortizing term loans with certain financial institutions. Similar to the IKB loans discussed above, the financial covenants of these borrowings are calculated by reference to the Credit Agreement. On February 28, 2023, one of these term loans for €20.0 million was fully extinguished. The remaining term loan has a principal balance of $1.0 million and matures in March 2024.

Aggregated unamortized deferred debt issuance costs incurred in connection with all of our outstanding debt totaled $17.5 million at December 31, 2023. The deferred costs are being amortized on a straight-line basis over the life of the underlying instruments. Amortization expense related to deferred debt issuance costs totaled $3.0 million, $1.9 million and $0.9 million in 2023, 2022 and 2021, respectively.

As of December 31, 2023 and 2022, we had $5.7 million and $4.7 million, respectively, of letters of credit issued to us by certain financial institutions. The letters of credit, which reduce amounts available under our Revolving Credit Facility, provide financial assurances for the performance of long-term monitoring activities associated with the Fox River environmental matter and for the benefit of certain state workers compensation insurance agencies in conjunction with our self-insurance program. We bear the credit risk on this amount to the extent that we do not comply with the provisions of certain agreements. No amounts are outstanding under the letters of credit.
