DEBT INDEBTEDNESS
On November 1, 2021, we entered into a second amended and restated credit agreement with BMO Harris Bank N.A. ("BMO"). This agreement provides us with a senior secured credit facility (the "2021 Credit Facility") consisting of a $350 million term loan B secured loan (the “Term Loan Facility”) and a $35 million revolving credit facility (the “Revolving Loan Facility”) with an uncommitted option to increase incremental loans under the 2021 Credit Facility, subject to an incremental cap. The Revolving Loan Facility includes a $10 million letter of credit subfacility and $10 million swingline subfacility. Digi may use proceeds of the Revolving Loan Facility in the future for general corporate purposes. This loan replaced our syndicated senior secured credit agreement with BMO that was entered into on March 15, 2021 and replaced the remaining balance of our revolver with this new term loan. This prior agreement provided us with committed credit facilities ("Prior Credit Facility") consisting of a $200 million revolving loan.
The debt issuance costs and remaining balance under the Prior Credit Facility totaled $2.3 million at November 1, 2021. Of this amount $1.9 million was written off and included in interest expense upon the entry into the new amendment and $0.4 million is being amortized over the term of the amended loan and reported in interest expense. Digi incurred an additional $11.7 million and $1.7 million in debt issuance costs relating to the November 1, 2021 and December 22, 2021 amendments, respectively. These amounts are being amortized over the term of the amended loan and reported in interest expense.
On December 22, 2021, Digi entered into a third amended and restated credit agreement with BMO. Digi refinanced the Term Loan Facility and Revolving Loan Facility under its existing credit agreement entered into on November 1, 2021, but did not receive any additional proceeds from nor modify the amounts of any facilities or subfacilities contained within that credit agreement.
On December 7, 2023, Digi entered into a credit agreement (the “Credit Agreement”) with BMO Bank N.A. (“BMO”), as administrative and collateral agent, BMO Capital Markets Corp., BofA Securities, Inc. and MUFG Bank, Ltd., as joint lead arrangers and joint bookrunners, and the several banks and other financial institutions or entities from time to time party thereto as lenders (the “Lenders”). The Credit Agreement provides Digi with a senior secured credit facility (the “2023 Credit Facility”). The 2023 Credit Facility includes a $250 million senior secured revolving credit facility (the “Revolving Loan”), with an uncommitted accordion feature that provides for additional borrowing capacity of up to the greater of $95 million or one hundred percent of trailing twelve month adjusted earnings before interest, taxes, depreciation, and amortization ("EBITDA"). The 2023 Credit Facility also contains a $10 million letter of credit sublimit and $10 million swingline sub-facility. Digi may use the proceeds of the 2023 Credit Facility in the future for general corporate purposes.
Digi borrowed a total of $215 million under the 2023 Credit Facility to repay all obligations and to pay related fees and expenses under the Third Amended and Restated Credit Agreement dated as of December 22, 2021 (the “2021 Credit Facility”), by and among Digi, as the borrower, BMO, as administrative agent and collateral agent, BMO Capital Markets Corp., as sole lead arranger and bookrunner, and the other lenders from time-to-time party thereto. The 2021 Credit Facility consisted of a $350 million term loan B secured loan and a $35 million revolving credit facility that included a $10 million letter of credit subfacility and $10 million swingline subfacility.
Borrowings under the 2023 Credit Facility bear interest at a rate per annum equal to Term SOFR with a floor of 0.00% for an interest period of one, three, or six months as selected by Digi, reset at the end of the selected interest period (or a replacement benchmark rate if Term SOFR is no longer available) plus the applicable margin or a base rate plus the applicable margin. The base rate is determined by reference to the highest of BMO’s prime rate, the rate determined by BMO to be the average rate of Federal funds in the secondary market plus 0.50%, or one-month SOFR plus 1.00%. The applicable margin for loans under the 2023 Credit Facility is in a range of 1.75% to 2.75% for Term SOFR loans and 0.75% to 1.75% for base rate loans, depending on Digi’s total net leverage ratio. All borrowings from October through May were made at Term SOFR for a one-month interest election period plus an applicable margin of 2.50%. All borrowings from June through September were made at Term SOFR for a one-month interest election period plus an applicable margin of 2.25%. Our weighted average interest rate for our 2023 Credit Facility was 7.46% as of September 30, 2024.
In addition to paying interest on the outstanding principal, Digi is required to pay a commitment fee on the unutilized commitments under the 2023 Credit Facility. The commitment fee is between 0.20% and 0.35% depending on Digi’s total net leverage ratio. Our weighted average Revolving Loan commitment fee was 0.25% as of September 30, 2024. The Credit Facility is secured by substantially all of the property of Digi and its domestic subsidiaries.
6. INDEBTEDNESS (CONTINUED)
The debt issuance costs and remaining balance under the 2021 Credit Facility totaling $9.7 million at December 7, 2023 were written off and included in other expenses upon the entry into the Credit Agreement. Digi incurred an additional $1.3 million in debt issuance costs upon entry into the Credit Agreement, with this amount amortized over the term of the Credit Agreement and reported in interest expense.
The Revolving Loan is due in a lump sum payment at maturity December 7, 2028, if any amounts are drawn. The fair value of the Revolving Loan approximated carrying value at September 30, 2024.
