(A)

Our revolving credit facility, as amended (the “Working Capital Revolver Loan”), provides for advances up to $65 million (the “Maximum Revolver Amount”), based on specific percentages of eligible accounts receivable and inventories and up to $10 million of letters of credit. We had outstanding letters of credit as of September 30, 2023 of $2.0 million, which reduces the amount available for borrowing under the Working Capital Revolver Loan. At September 30, 2023, our available borrowings under our Working Capital Revolver Loan were approximately $42.4 million. The maturity date of the Working Capital Revolver Loan is on the earlier of (i) the date that is 90 days prior to the earliest stated maturity date of the Senior Secured Notes (unless refinanced or repaid) and (ii) February 26, 2024. Subject to certain conditions and subject to lender approval, the Maximum Revolver Amount may increase up to an additional $10 million. The Working Capital Revolver Loan also provides for a springing financial covenant (the “Financial Covenant”), which requires that, if the borrowing availability is less than 10.0% of the total revolver commitments, then the borrowers must maintain a minimum fixed charge coverage ratio of not less than 1.00 to 1.00. The Financial Covenant, if triggered, is tested monthly.

Interest accrues on outstanding borrowings under the Working Capital Revolver Loan at a rate equal to, at our election, either (a) SOFR for an interest period selected by us plus a SOFR adjustment equal to 0.10% per annum plus an applicable margin equal to 1.50% per annum or 1.75% per annum, depending on borrowing availability under the Working Capital Revolver Loan, or (b) Wells Fargo Capital Finance’s prime rate plus an applicable margin equal to 0.50% per annum or 0.75% per annum, depending on borrowing availability under the Working Capital Revolver Loan. Interest is paid quarterly, if applicable. During the second quarter of 2023 the LIBOR rate component included in our Working Capital Revolver Loan was converted to SOFR as use of LIBOR was discontinued.

On October 14, 2021, LSB completed the issuance and sale of $500 million aggregate principal amount of the Notes of its 6.25% Senior Secured Notes due 2028 (the “Notes”), pursuant to an indenture (the “Indenture”), dated as of October 14, 2021. The Notes were issued at a price equal to 100% of their face value.

On March 8, 2022, LSB completed the issuance and sale of an additional $200 million aggregate principal amount of the Notes (the “New Notes”), which were issued pursuant to the Indenture (the Notes together with the New Notes, the “Senior Secured Notes”). The New Notes were issued at a price equal to 100% of their face value, plus accrued interest from October 14, 2021 to March 7, 2022. The Senior Secured Notes mature on October 15, 2028. Interest is to be paid in arrears on May 15 and October 15.

During the second quarter of 2023 we repurchased $125 million in principal amount of our Senior Secured Notes for approximately $114.3 million, which was accounted for as an extinguishment of debt. Including our write-off of the associated remaining portion of unamortized debt issuance costs, we recognized a gain on extinguishment of approximately $8.6 million.
