(1) the credit facility matures in August 2028. At the end of March 31, 2024 and December 31, 2023, the interest rate in effect was 3.34% and 3.49%, respectively, including the effect of interest rate hedging transactions, as described below.

On August 16, 2023, we entered into a $800 million unsecured committed Five-Year Revolving Credit Facility Agreement (the “Amended Credit Agreement”). The applicable interest rate for borrowings under the Amended Credit Agreement is based on Term SOFR plus a spread, which is based on our leverage ratio (as defined in the Amended Credit Agreement) at the time of a borrowing as follows:


Leverage Ratio	Commitment Fee	ABR Spread	Term Benchmark/ Daily Simple SOFR Spread
<1.00:1.00	0.275%	0.500%	1.500%
≥ 1.00:1.00 and < 2.00:1.00	0.300%	0.625%	1.625%
≥ 2.00:1.00 and < 3.00:1.00	0.325%	0.750%	1.750%
≥ 3.00:1.00	0.350%	1.000%	2.000%

As of March 31, 2024, the applicable interest rate for borrowings under the Amended Credit Agreement was based on one-month term SOFR plus the spread, which was 1.625%.

As of March 31, 2024, there was $429 million of borrowings outstanding under the Amended Credit Agreement and we had borrowings available of $371 million, based on our maximum leverage ratio and our Consolidated EBITDA (as defined in the Amended Credit Agreement).

The Amended Credit Agreement contains customary terms including affirmative covenants, negative covenants and events of default. Under the Amended Credit Agreement, we are required to maintain a leverage ratio (as defined in the Credit Agreement) of not greater than 3.75 to 1.00, or 4.25 to 1.00 after a significant acquisition. We are also required to maintain a minimum interest coverage ratio (as defined in the Credit Agreement) of greater than 3.00 to 1.00.

As of March 31, 2024, our leverage ratio was 1.17 to 1.00 (as defined in the Amended Credit Agreement) and our interest coverage ratio was 14.38 to 1.00. If our leverage ratio exceeds 3.50 to 1.00, then we are restricted in paying dividends to a maximum amount of $40 million in a calendar year. As of March 31, 2024, we were in compliance with all applicable covenants. We anticipate continued compliance in each of the next four quarters while continuing to monitor future compliance based on current and future economic conditions.

The borrowings are guaranteed by certain of the Company’s subsidiaries, including all significant U.S. subsidiaries (subject to certain exceptions), as defined in the Amended Credit Agreement. Our ability to borrow additional amounts under the Amended Credit Agreement is conditional upon the absence of any defaults, as well as the absence of any material adverse change (as defined in the Amended Credit Agreement).

In 2021, we entered into interest rate swap agreements for the period of October 17, 2022 through October 27, 2024. These transactions had the effect of fixing the LIBOR portion of the effective interest rate (before addition of the spread) on $350 million of indebtedness. We amended the swap agreements on June 29, 2023 replacing the LIBOR (in preparation for the cessation of LIBOR) with SOFR and adjusting the spread.

We pay a fixed blended rate of 0.8828% through October 27, 2024 on $350 million and the counterparties pay a floating rate based on the one-month term SOFR at each monthly calculation date, which on March 18, 2024 was 5.33%. As of March 31, 2024, the all-in rate on the $350M of debt was 2.51%. Upon the expiration of the interest rate swap on October 27, 2024, our interest cost will increase significantly. Beginning in October 2024, our interest cost will be calculated using a floating rate based on the one-month term SOFR.

The interest rate swaps are accounted for as a hedge of future cash flows, as further described in Note 15, Fair-Value Measurements. No cash collateral was received or pledged in relation to the swap agreements.

On August 31, 2023, the Company acquired Heimbach. The Company assumed Heimbach’s bank debt in the amount of $32.7 million. The bank debt is held by several European financial institutions, with maturity dates ranging from June 30, 2024 to June 30, 2031. At March 31, 2024 and December 31, 2023, the foreign debt was $10.1 million and $10.9 million, respectively, of which $4.4 million and $4.2 million, respectively, was classified as Current maturities on long-term debt.
