(2)During the year ended December 31, 2023, we completed our transition from LIBOR to Term SOFR rates for all of our variable rate facilities, with such transition having taken effect at the interest reset date for each such facility.

(3)Advances under our unsecured revolving credit facilities accrue interest at Term SOFR plus a 0.10% credit adjustment spread plus an interest rate margin primarily at 1.80%. Based on applicable Term SOFR rates, as of December 31, 2023, the maximum interest rate under the unsecured credit facilities was 7.50%. We also pay a facility fee primarily at 0.20% of the total commitments under such facility.

In January 2023, we amended and extended the majority of our two unsecured revolving credit facilities. The amendment extended the maturities of $2.3 billion of the $3.0 billion aggregate revolving capacity by one year to April 2025, with the remainder maturing in April 2024. In October 2023, we refinanced both unsecured revolving credit facilities as well as the $502 million unsecured term loan scheduled to fully mature in October 2024, bringing our aggregate revolving credit capacity to $3.5 billion. As of December 31, 2023, $1.7 billion of the commitments are scheduled to mature in October 2026, $1.7 billion of the commitments are scheduled to mature in October 2028, and the remaining $97 million of commitments are scheduled to mature in April 2025. As of December 31, 2023, we had undrawn capacity of $2.6 billion under our unsecured revolving credit facilities.

In June 2023, our remaining $350 million of the 4.25% Convertible Senior Notes matured. The notes were settled using a combination of $338 million in cash, and the issuance of approximately 374,000 shares of common stock. The issuance of equity increased additional paid in capital by an immaterial amount.

In November 2023, our remaining $225 million of the 2.875% Convertible Senior Notes matured. The notes were settled using a combination of $225 million in cash and the issuance of approximately 147,000 shares of common stock. The issuance of equity increased additional paid in capital by an immaterial amount.

In February 2023, we issued $700 million aggregate principal amount of 7.25% senior guaranteed notes due January 2030 ("7.25% Priority Guaranteed Notes"). Upon closing, we terminated our commitment for the $700 million 364-day term loan facility. In addition, the remaining $350 million backstop committed financing was also terminated upon closing, which resulted in an immaterial loss on extinguishment of debt.

In June 2023, we took delivery of Silver Nova. To finance the delivery, we borrowed a total of $503 million under the committed financing agreement, resulting in an unsecured term loan which is 95% guaranteed by Euler Hermes.

During 2023, we repaid the remaining $1.4 billion of our 11.50% secured senior notes due June 2025, which resulted in a total loss on extinguishment of debt of $105 million that was recognized within Interest expense, net of interest capitalized within our consolidated statements of comprehensive income (loss) for the year ended December 31, 2023.

In October 2023, in connection with the revolving credit facilities refinancing described above, we paid the remaining $502 million of the $0.6 billion unsecured term loan due October 2023 which was previously amended in September 2022 to extend the maturity date of advances under the facilities held by consenting lenders by 12 months to October 2024.

In August 2022, we issued $1.15 billion of convertible senior notes which accrue interest at 6.00% and mature in August 2025. Upon conversion election, we may deliver shares of our common stock, cash, or a combination of common stock and cash, at our election. The initial conversion rate per $1,000 principal amount of the convertible notes is 19.9577 shares of our common stock, which is equivalent to an initial conversion price of approximately $50.11 per share, subject to adjustment in certain circumstances. Prior to May 15, 2025, the convertible notes will be convertible at the option of holders during certain periods, and only under certain circumstances set forth in the indenture.

On or after May 15, 2025, the convertible notes will be convertible at any time until the close of business on the second scheduled trading day immediately preceding their maturity date. We received gross proceeds from the offering of $1.15 billion, which we used to repurchase $800 million aggregate principal amount of our 4.25% convertible senior notes due June 15, 2023 and $350 million aggregate principal amount of our 2.875% convertible senior notes due November 15, 2023 (which were settled in November 2023 as described above) in privately negotiated transactions. The $1.15 billion repayment resulted in a total loss on the extinguishment of debt of $12.8 million, which was recognized within Interest expense, net of interest capitalized within our consolidated statements of comprehensive loss for the year ended December 31, 2022.

In August 2022, we issued $1.25 billion of senior unsecured notes which accrue interest at 11.625% that mature in August 2027.

We used the combined net proceeds, of the respective offerings, together with cash on hand, to fund the redemption, including call premiums, fees and expenses, of our outstanding 9.125% senior priority guaranteed notes due 2023 and 10.875% senior secured notes due 2023, which resulted in a total loss on extinguishment of debt of $77 million, which was recognized within Interest expense, net of interest capitalized within our consolidated statements of comprehensive loss for the year ended December 31, 2022.

Except for the term loans we incurred to acquire Celebrity Flora and Silver Moon, all of our unsecured ship financing term loans are guaranteed by the export credit agency in the respective country in which the ship is constructed. For the majority of the loans as of December 31, 2023, we pay to the applicable export credit agency, depending on the financing agreement, an upfront fee of 2.35% to 5.48% of the maximum loan amount in consideration for these guarantees. We amortize the fees that are paid upfront over the life of the loan. We classify these fees within Amortization of debt issuance costs, discounts and premiums in our consolidated statements of cash flows. Prior to the loan being drawn, we present these fees within Other assets in our consolidated balance sheets. Once the loan is drawn, such fees are classified as a discount to the related loan, or contra-liability account, within Current portion of long-term debt or long-term debt.

Our revolving credit facilities, the majority of our term loans, and certain of our credit card processing agreements, contain covenants that require us, among other things, to maintain a fixed charge coverage ratio, limit our net debt-to-capital ratio, maintain minimum liquidity, and under certain facilities, to maintain a minimum stockholders' equity. As of December 31, 2023, our credit facility amendments require us to prepay outstanding deferred amounts of $910 million, if we elect to pay dividends or complete share repurchases. As of December 31, 2023, we were in compliance with our debt covenants and we estimate we will be in compliance for the next twelve months.
