permitted liens and certain other exceptions, by first priority liens on the same collateral that secures the obligations under Adtalem’s senior secured credit facilities.
At any time prior to March 1, 2024, we could have redeemed all or a part of the Notes at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus a make-whole premium set forth in the Indenture and accrued and unpaid interest, if any, to, but not including, the redemption date. We may redeem the Notes, in whole or in part, at any time on or after March 1, 2024 at redemption prices equal to 102.75%, 101.375%, and 100% of the principal amount of the Notes redeemed if the redemption occurs during the twelve-month periods beginning on March 1 of the years 2024, 2025, and 2026 and thereafter, respectively, in each case plus accrued and unpaid interest, if any, thereon to, but not including, the applicable redemption date. In addition, at any time prior to March 1, 2024, Adtalem could have redeemed up to 40% of the aggregate principal amount of the Notes at a redemption price equal to 105.5% of the aggregate principal amount of the Notes redeemed, plus accrued and unpaid interest, if any, to, but not including, the redemption date, with the net cash proceeds from one or more qualifying equity offerings.
On April 11, 2022, we repaid $373.3 million of Notes at a price equal to 100% of the principal amount of the Notes. During June 2022, we repurchased on the open market an additional $20.8 million of Notes at a price equal to approximately 90% of the principal amount of the Notes. This debt was subsequently retired. During the first quarter of fiscal year 2023, we repurchased on the open market an additional $0.9 million of Notes at a price equal to approximately 92% of the principal amount of the Notes, resulting in a gain on extinguishment of debt of $0.1 million recorded within interest expense in the Consolidated Statements of Income for the nine months ended March 31, 2023. This debt was subsequently retired. The principal balance of the Notes is $405.0 million as of March 31, 2024.
Accrued interest on the Notes of $1.9 million and $7.4 million is recorded within accrued liabilities on the Consolidated Balance Sheets as of March 31, 2024 and June 30, 2023, respectively.
Credit Agreement
On August 12, 2021, in connection with the Walden acquisition, Adtalem entered into its new credit agreement (the “Credit Agreement”) that provides for (1) a $850.0 million senior secured term loan (“Term Loan B”) with a maturity date of August 12, 2028 and (2) a $400.0 million senior secured revolving loan facility (“Revolver”) with a maturity date of August 12, 2026. We refer to the Term Loan B and Revolver collectively as the “Credit Facility.” The Revolver has availability for letters of credit and currencies other than U.S. dollars of up to $400.0 million.
On June 27, 2023, Adtalem entered into Amendment No. 1 to Credit Agreement, identifying the Secured Overnight Financing Rate (“SOFR”) as the benchmark rate to replace LIBOR for eurocurrency rate loans within the Credit Agreement effective the first quarter of fiscal year 2024.
Term Loan B
Prior to January 26, 2024, borrowings under the Term Loan B bore interest at Adtalem’s option at a rate per annum equal to SOFR, subject to a SOFR floor of 0.75%, plus an applicable margin ranging from 4.00% to 4.50% for eurocurrency term loan borrowings or 3.00% to 3.50% for alternative base rate (“ABR”) borrowings depending on Adtalem’s net first lien leverage ratio for such period. On January 26, 2024, we repriced our Term Loan B loan resulting in a 0.50% reduction in our margin interest rate. As of January 26, 2024, borrowings under the Term Loan B bear interest at Adtalem’s option at a rate per annum equal to SOFR, subject to a SOFR floor of 0.75%, plus an applicable margin ranging from 3.50% to 4.00% for eurocurrency term loan borrowings or 2.50% to 3.00% for ABR borrowings depending on Adtalem’s net first lien leverage ratio for such period.
As of March 31, 2024, the interest rate for borrowings under the Term Loan B facility was 8.83%, which approximated the effective interest rate. The Term Loan B originally required quarterly installment payments of $2.125 million beginning on March 31, 2022. On March 11, 2022, we made a prepayment of $396.7 million on the Term Loan B. With that prepayment, we are no longer required to make quarterly installment payments. We made additional Term Loan B prepayments of $100.0 million, $50.0 million, and $50.0 million on September 22, 2022, November 22, 2022, and January 26, 2024, respectively. The principal balance of the Term Loan B is $253.3 million as of March 31, 2024.
