market conditions at the time drawn (the “Class B Notes”) and (ii) $400 million aggregate principal amount of 8.00% senior secured notes due five years after the issue date (the “Backstop Notes”). The Class B Notes and the Backstop Notes are subject to a quarterly commitment fee of 0.75% for so long as the commitments with respect to Class B Notes or the Backstop Notes, as applicable, are outstanding, which fee will be increased to 1.00% if NCLC extends the commitments through February 2025 at its election. If drawn, the Class B Notes will be subject to an issue fee of 2.00%, and the Backstop Notes will be subject to a quarterly duration fee of 1.50%, as well as an issue fee of 3.00%.
In February 2023, in connection with the execution of the amended commitment letter, NCLC issued $250 million aggregate principal amount of 9.75% senior secured notes due 2028 (the “Class A Notes” and, collectively with the Class B Notes and the Backstop Notes, the “Notes”), subject to an issue fee of 2.00%. NCLC used the net proceeds from the Class A Notes for general corporate purposes. NCLC may redeem the Class A Notes at its option, in whole or in part, at any time and from time to time prior to February 22, 2025, at a “make-whole” redemption price, plus accrued and unpaid interest and additional amounts, if any, to, but excluding, the redemption date. NCLC may redeem the Class A Notes at its option, in whole or in part, at any time and from time to time on or after February 22, 2025, at the redemption prices set forth in the indenture governing the Class A Notes, plus accrued and unpaid interest and additional amounts, if any, to, but excluding, the redemption date. The Class A Notes pay interest at 9.75% per annum, quarterly on February 15, May 15, August 15 and November 15 of each year, to holders of record at the close of business on the immediately preceding February 1, May 1, August 1 and November 1, respectively.
The Class A Notes are, and the Class B Notes and the Backstop Notes, if issued, will be, secured by first-priority interests in, among other things and subject to certain agreed security principles, shares of capital stock in certain guarantors, our material intellectual property and two islands that we use in the operations of our cruise business. The Class A Notes are, and the Class B Notes and the Backstop Notes, if issued, will be, guaranteed by our subsidiaries that own the property that secures the Notes as well as certain additional subsidiaries whose assets do not secure the Notes.
The indenture governing the Class A Notes includes requirements that, among other things and subject to a number of qualifications and exceptions, restrict the ability of NCLC and its restricted subsidiaries, as applicable, to (i) incur or guarantee additional indebtedness; (ii) pay dividends or distributions on, or redeem or repurchase, equity interests and make other restricted payments; (iii) make investments; (iv) consummate certain asset sales; (v) engage in certain transactions with affiliates; (vi) grant or assume certain liens; and (vii) consolidate, merge or transfer all or substantially all of their assets.
In February 2023, NCLC entered into a Backstop Agreement with Morgan Stanley & Co. LLC (“MS”), pursuant to which MS agreed to provide backstop committed financing to refinance and/or repay in whole or in part amounts outstanding under the Senior Secured Credit Facility. Pursuant to the Backstop Agreement, we could, at our sole option, issue and sell to MS (subject to the satisfaction of certain conditions) five-year senior unsecured notes up to an aggregate principal amount sufficient to generate gross proceeds of $300 million at any time between October 4, 2023 and January 2, 2024. As a result of the refinancing of the Senior Secured Credit Facility in October 2023 (discussed below), the backstop committed financing is no longer applicable.
In April 2023, $82.5 million in aggregate principal amount of the Revolving Loan Facility due January 2024 was assigned to a new lender, and the maturity date was extended by one year to January 2025. The terms of the assigned principal were the same as the existing lenders who extended commitments in December 2022 under Amendment No. 4 to the Senior Secured Credit Facility.
In April 2023, we took delivery of Oceania Cruises’ Vista. We had export credit financing in place for 80% of the contract price. The associated $632.6 million term loan bears interest at a fixed rate of 3.64% with a maturity date of April 30, 2035. Principal and interest payments are payable semiannually.
In May and June 2023, certain of NCLC’s export-credit backed facilities were amended to replace LIBOR with Term SOFR. In connection with these amendments, the Company adopted Accounting Standards Update (“ASU”) No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”), which provided guidance to alleviate the burden in accounting for reference rate reform by allowing certain expedients and exceptions in applying GAAP to contracts, hedging relationships and other transactions impacted
