Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	General Description of Business Carnival Corporation was incorporated in Panama in 1974 and Carnival plc was incorporated in England and Wales in 2000. Together with their consolidated subsidiaries, they are referred to collectively in these consolidated financial statements and elsewhere in this 2022 Annual Report as “Carnival Corporation & plc,” “our,” “us” and “we.” The consolidated financial statements include the accounts of Carnival Corporation and Carnival plc and their respective subsidiaries. We are the largest global cruise company and among the largest leisure travel companies with a portfolio of world-class cruise lines. With operations in North America, Australia, Europe and Asia, our portfolio features – AIDA Cruises, Carnival Cruise Line, Costa Cruises, Cunard, Holland America Line, Princess Cruises, P&O Cruises (Australia), P&O Cruises (UK) and Seabourn. DLC Arrangement Carnival Corporation and Carnival plc operate a dual listed company (“DLC”) arrangement, whereby the businesses of Carnival Corporation and Carnival plc are combined through a number of contracts and provisions in Carnival Corporation’s Articles of Incorporation and By-Laws and Carnival plc’s Articles of Association. The two companies operate as a single economic enterprise with a single senior management team and identical Boards of Directors, but each has retained its separate legal identity. Each company’s shares are publicly traded on the New York Stock Exchange (“NYSE”) for Carnival Corporation and the London Stock Exchange for Carnival plc. The Carnival plc American Depositary Shares are traded on the NYSE. The constitutional documents of each company provide that, on most matters, the holders of the common equity of both companies effectively vote as a single body. The Equalization and Governance Agreement between Carnival Corporation and Carnival plc provides for the equalization of dividends and liquidation distributions based on an equalization ratio and contains provisions relating to the governance of the DLC arrangement. Because the equalization ratio is 1 to 1, one share of Carnival Corporation common stock and one Carnival plc ordinary share are generally entitled to the same distributions. Under deeds of guarantee executed in connection with the DLC arrangement, as well as stand-alone guarantees executed since that time, each of Carnival Corporation and Carnival plc have effectively cross guaranteed all indebtedness and certain other monetary obligations of each other. Once the written demand is made, the holders of indebtedness or other obligations may immediately commence an action against the relevant guarantor. Under the terms of the DLC arrangement, Carnival Corporation and Carnival plc are permitted to transfer assets between the companies, make loans to or investments in each other and otherwise enter into intercompany transactions. In addition, the cash flows and assets of one company are required to be used to pay the obligations of the other company, if necessary. Given the DLC arrangement, we believe that providing separate financial statements for each of Carnival Corporation and Carnival plc would not present a true and fair view of the economic realities of their operations. Accordingly, separate financial statements for Carnival Corporation and Carnival plc have not been presented. Liquidity and Management’s Plans In the face of the global impact of COVID-19, we paused our guest cruise operations in March 2020 and began resuming guest cruise operations in 2021. Based on the evolving nature of COVID-19 and our ongoing collaboration with local and national public health authorities, we have responsibly relaxed our related protocols, including greatly reducing or eliminating testing requirements and vaccination protocols to more closely align with the broader travel industry and strengthening our competitiveness. As part of our liquidity management, we rely on estimates of our future liquidity, which includes numerous assumptions that are subject to various risks and uncertainties. The principal assumptions used to estimate our future liquidity consist of: • Our continued cruise operations and expected timing of cash collections for cruise bookings • Expected increases in revenue in 2023 on a per passenger basis compared to 2019, particularly with the responsible relaxation of COVID-19 related protocols aligning towards land-based vacation alternatives and strengthening our competitiveness • Expected improvement in occupancy on a year-over-year basis returning to historical levels in the summer of 2023 • Stabilization of fuel prices around November 2022 year-end prices • Continued stabilization of inflationary pressures on costs, moderated by a larger-more efficient fleet as compared to 2019 In addition, we make certain assumptions about new ship deliveries, improvements and removals, and consider the future export credit financings that are associated with the new ship deliveries. We have a substantial debt balance as a result of the pause in guest cruise operations and require a significant amount of liquidity or cash provided by operating activities to service our debt. In addition, the continued effects of the pandemic, inflation, higher fuel prices, higher interest rates and fluctuations in foreign currency rates are collectively having a material negative impact on our financial results. The full extent of the collective impact of these items is uncertain and may be amplified by our substantial debt balance. We believe we have made reasonable estimates and judgments of the impact of these events within our consolidated financial statements and there may be changes to those estimates in future periods. For almost three years, we have taken appropriate actions to manage our liquidity, including completing various capital market transactions, obtaining relevant financial covenant amendments or waivers (see Note 5 - “Debt”), accelerating the removal of certain ships from the fleet, and during the pause, reducing capital expenditures and operating expenses. As of November 30, 2022, 97% of our capacity has resumed guest cruise operations and is serving guests. Based on these actions and our assumptions, and considering our $8.6 billion of liquidity including cash, restricted cash from the 2028 Senior Priority Notes which became unrestricted in December 2022 and borrowings available under our $1.7 billion, €1.0 billion and £0.2 billion multi-currency revolving credit facility (the “Revolving Facility”) at November 30, 2022, we believe that we have sufficient liquidity to fund our obligations and expect to remain in compliance with our financial covenants for at least the next twelve months from the issuance of these financial statements. We will continue to pursue various opportunities to raise additional capital to fund obligations associated with future debt maturities and/or to extend the maturity dates associated with our existing indebtedness including our Revolving Facility and obtain relevant financial covenant amendments or waivers, if needed. Actions to raise capital may include issuances of debt, convertible debt or equity in private or public transactions or entering into new and extended credit facilities.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation We consolidate entities over which we have control, as typically evidenced by a voting control of greater than 50% or for which we are the primary beneficiary, whereby we have the power to direct the most significant activities and the obligation to absorb significant losses or receive significant benefits from the entity. We do not separately present our noncontrolling interests in the consolidated financial statements since the amounts are immaterial. For affiliates we do not control but where significant influence over financial and operating policies exists, as typically evidenced by a voting control of 20% to 50%, the investment is accounted for using the equity method. For 2021, we reclassified $14 million from prepaid expenses and other to restricted cash to conform to the current year presentation. Preparation of Financial Statements The preparation of our consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the amounts reported and disclosed in our consolidated financial statements. The full extent to which the effects of the pandemic, inflation, higher fuel prices, higher interest rates and fluctuations in foreign currency rates will directly or indirectly impact our business, operations, results of operations and financial condition, including our valuation of goodwill and trademarks, impairment of ships and collectability of trade and notes receivables, will depend on future developments that are uncertain. We have made reasonable estimates and judgments of such items within our financial statements and there may be changes to those estimates in future periods. Actual results may differ from the estimates used in preparing our consolidated financial statements. All material intercompany balances and transactions are eliminated in consolidation. Cash and Cash Equivalents Cash and cash equivalents include investments with maturities of three months or less at acquisition which are stated at cost and present insignificant risk of changes in value. Restricted Cash Restricted cash is classified as short-term or long-term based on the expected timing of our ability to access or use the amounts. The long-term portion is included within other assets. Substantially all restricted cash as of November 30, 2022 relates to the net proceeds from the issuance of our 2028 Senior Priority Notes, which became unrestricted in December 2022. Short-term Investments Short-term investments include investments with maturities of three to 12 months which are stated at cost and present insignificant risk of changes in value. Trade and Other Receivables Although we generally require full payment from our customers prior to or concurrently with their cruise, we grant credit terms to a relatively small portion of our revenue source. We have receivables from credit card merchants and travel agents for cruise ticket purchases and onboard revenue. These receivables are included within trade and other receivables, net. We have agreements with a number of credit card processors that transact customer deposits related to our cruise vacations. Certain of these agreements allow the credit card processors to request, under certain circumstances, that we provide a reserve fund in cash. These reserve funds are included in other assets. Inventories Inventories consist substantially of food, beverages, hotel supplies, fuel and retail merchandise, which are all carried at the lower of cost or net realizable value. Cost is determined using the weighted-average or first-in, first-out methods. Property and Equipment Property and equipment are stated at cost less accumulated depreciation and any impairment charges. We capitalize interest as part of the cost of capital projects incurred during construction. Depreciation is computed using the straight-line method over our estimated useful lives of the assets to a residual value, as a percentage of original cost, as follows: Years Residual Ships 30 15% Ship improvements 3-30 0% Buildings and improvements 10-40 0% Computer hardware and software 2-12 0% Transportation equipment and other 3-20 0% Leasehold improvements, including port facilities Shorter of the remaining lease term or related asset life (3-30) 0% The cost of ships under construction includes progress payments for the construction of new ships, as well as design and engineering fees, capitalized interest, construction oversight costs and various owner supplied items. Any liquidated damages received from shipyards are recorded as reductions to the cost basis of the ship. We have a capital program for the improvement of our ships and for asset replacements to enhance the effectiveness and efficiency of our operations; to comply with, or exceed, all relevant legal and statutory requirements related to health, environment, safety, security and sustainability; and to gain strategic benefits or provide improved product innovations to our guests. We account for ship improvement costs, including replacements of certain significant components and parts, by capitalizing those costs we believe add value to our ships and have a useful life greater than one year and depreciating those improvements over their estimated remaining useful life. The costs of repairs and maintenance, including those incurred when a ship is taken out-of-service for scheduled maintenance, and minor improvement costs and expenses, are charged to expense as incurred. In addition, specifically identified or estimated cost and accumulated depreciation of previously capitalized ship components are written-off upon retirement, which may result in a loss on disposal that is also included in other operating expenses. We have estimated our ships’ useful lives at 30 years and residual values at 15% of our original ship cost. Our ship useful life and residual value estimates take into consideration the estimated weighted-average useful lives of the ships' major component systems, such as hull, superstructure, main electric, engines and cabins. We also take into consideration the impact of technological changes, historical useful lives of similarly-built ships, long-term cruise and vacation market conditions and regulatory changes, including those related to the environment and climate change. We determine the residual value of our ships based on our long-term estimates of their resale value at the end of their useful life to us but before the end of their physical and economic lives to others, historical resale values of our and other cruise ships as well as our expectations of the long-term viability of the secondary cruise ship market. We review estimated useful lives and residual values for reasonableness whenever events or circumstances significantly change. We evaluate ship asset impairments at the individual ship level which is the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. We review our ships for impairment whenever events or circumstances indicate that the carrying value of a ship may not be recoverable. If estimated future cash flows are less than the carrying value of a ship, an impairment charge is recognized to the extent its carrying value exceeds its estimated fair value. Leases Substantially all of our leases for which we are the lessee are operating leases of port facilities and real estate and are included within operating lease right-of-use assets, long-term operating lease liabilities and current portion of operating lease liabilities in our Consolidated Balance Sheets. We have port facilities and real estate lease agreements with lease and non-lease components, and in such cases, we account for the components as a single lease component. We do not recognize lease assets and lease liabilities for any leases with an original term of less than one year. For some of our port facilities and real estate lease agreements, we have the option to extend our current lease term by 1 to 10 years. Generally, we do not include renewal options as a component of our present value calculation as we are not reasonably certain that we will exercise the options. As most of our leases do not have a readily determinable implicit rate, we estimate the incremental borrowing rate (“IBR”) to determine the present value of lease payments. We apply judgment in estimating the IBR including considering the term of the lease, the currency in which the lease is denominated, and the impact of collateral and our credit risk on the rate. We amortize our lease assets on a straight-line basis over the lease term. Goodwill and Other Intangibles Goodwill represents the excess of the purchase price over the fair value of identifiable net assets acquired in a business acquisition. We review our goodwill for impairment as of July 31 every year, or more frequently if events or circumstances dictate. All of our goodwill has been allocated to our reporting units. The impairment review for goodwill allows us to first assess qualitative factors to determine whether it is necessary to perform the more detailed quantitative goodwill impairment test. We would perform the quantitative test if our qualitative assessment determined it is more-likely-than-not that a reporting unit’s estimated fair value is less than its carrying amount. We may also elect to bypass the qualitative assessment and proceed directly to the quantitative test for any reporting unit. When performing the quantitative test, if the estimated fair value of the reporting unit exceeds its carrying value, no further analysis is required. However, if the estimated fair value of the reporting unit is less than the carrying value, goodwill is written down based on the difference between the reporting unit’s carrying amount and its fair value, limited to the amount of goodwill allocated to the reporting unit. Judgment is required in estimating the fair value of our reporting unit. Trademarks represent substantially all of our other intangibles. Trademarks are estimated to have an indefinite useful life and are not amortizable but are reviewed for impairment at least annually and as events or circumstances dictate. The impairment review for trademarks also allows us to first assess qualitative factors to determine whether it is necessary to perform a more detailed quantitative trademark impairment test. We would perform the quantitative test if our qualitative assessment determined it was more-likely-than-not that the trademarks are impaired. We may also elect to bypass the qualitative assessment and proceed directly to the quantitative test. Our trademarks would be considered impaired if their carrying value exceeds their estimated fair value. Equity Method Investments Equity method investments are initially recognized at cost and are included in other assets in the Consolidated Balance Sheets. Our proportionate interest in their results is included in other income (expense), net in the Consolidated Statements of Income. Debt and Debt Issuance Costs Debt is recorded at initial fair value, which normally reflects the proceeds received by us, net of debt issuance costs. Debt is subsequently stated at amortized cost. Debt issuance costs are generally amortized to interest expense using the straight-line method, which approximates the effective interest method, over the term of the debt. Debt issue discounts and premiums are generally amortized to interest expense using the effective interest rate method over the term of the debt. Derivatives and Other Financial Instruments We have in the past and may in the future utilize derivative and non-derivative financial instruments, such as foreign currency forwards, options and swaps, foreign currency debt obligations and foreign currency cash balances, to manage our exposure to fluctuations in certain foreign currency exchange rates. We use interest rate swaps primarily to manage our interest rate exposure to achieve a desired proportion of fixed and floating rate debt. Our policy is to not use financial instruments for trading or other speculative purposes. All derivatives are recorded at fair value. If a derivative is designated as a cash flow hedge, then the change in the fair value of the derivative is recognized as a component of AOCI until the underlying hedged item is recognized in earnings or the forecasted transaction is no longer probable. If a derivative or a non-derivative financial instrument is designated as a hedge of our net investment in a foreign operation, then changes in the effective portion of the fair value of the financial instrument are recognized as a component of AOCI to offset the change in the translated value of the designated portion of net investment being hedged until the investment is sold or substantially liquidated, while the impact attributable to components excluded from the assessment of hedge effectiveness is recorded in interest expense, net of capitalized interest, on a systematic and rational basis. For derivatives that do not qualify for hedge accounting treatment, the change in fair value is recognized in earnings. We classify the fair value of all our derivative contracts as either current or long-term, depending on the maturity date of the derivative contract. The cash flows from derivatives treated as cash flow hedges are classified in our Consolidated Statements of Cash Flows in the same category as the item being hedged. Derivative valuations are based on observable inputs such as interest rates and commodity price curves, forward currency exchange rates, credit spreads, maturity dates, volatilities, and cross currency basis spreads. We use the income approach to value derivatives for foreign currency options and forwards, interest rate swaps and cross currency swaps using observable market data for all significant inputs and standard valuation techniques to convert future amounts to a single present value amount, assuming that participants are motivated but not compelled to transact. Foreign Currency Translation and Transactions These financial statements are presented in U.S. dollars. Each foreign entity determines its functional currency by reference to its primary economic environment. Our most significant foreign entities utilize the U.S. dollar, Euro, Sterling or the Australian dollar as their functional currencies. We translate the assets and liabilities of our foreign entities that have functional currencies other than the U.S. dollar at exchange rates in effect at the balance sheet date. Revenues and expenses of these foreign entities are translated at the average rate for the period. Equity is translated at historical rates and the resulting foreign currency translation adjustments are included as a component of AOCI, which is a separate component of shareholders’ equity. Therefore, the U.S. dollar value of the non-equity translated items in our consolidated financial statements will fluctuate from period to period, depending on the changing value of the U.S. dollar versus these currencies. We execute transactions in a number of different currencies. At the date that the transaction is recognized, each asset, liability, revenue, expense, gain or loss arising from the transaction is measured and recorded in the functional currency of the recording entity using the exchange rate in effect at that date. At each balance sheet date, recorded monetary balances denominated in a currency other than the functional currency are adjusted using the exchange rate at the balance sheet date, with gains or losses recorded in other income or other expense, unless such monetary balances have been designated as hedges of net investments in our foreign entities. The net gains or losses resulting from foreign currency transactions were not material in 2022, 2021 and 2020. In addition, the unrealized gains or losses on our long-term intercompany receivables and payables which are denominated in a non-functional currency and which are not expected to be repaid in the foreseeable future are recorded as foreign currency translation adjustments included as a component of AOCI. Revenue and Expense Recognition Guest cruise deposits and advance onboard purchases are initially included in customer deposits when received. Customer deposits are subsequently recognized as cruise revenues, together with revenues from onboard and other activities, and all associated direct costs and expenses of a voyage are recognized as cruise costs and expenses, upon completion of voyages with durations of ten nights or less and on a pro rata basis for voyages in excess of ten nights. The impact of recognizing these shorter duration cruise revenues and costs and expenses on a completed voyage basis versus on a pro rata basis is not material. Certain of our product offerings are bundled and we allocate the value of the bundled services and goods between passenger ticket revenues and onboard and other revenues based upon the estimated standalone selling prices of those goods and services. Guest cancellation fees, when applicable, are recognized in passenger ticket revenues at the time of cancellation. Our sales to guests of air and other transportation to and from airports near the home ports of our ships are included in passenger ticket revenues, and the related costs of purchasing these services are included in transportation costs. The proceeds that we collect from the sales of third-party shore excursions are included in onboard and other revenues and the related costs are included in onboard and other costs. The amounts collected on behalf of our onboard concessionaires, net of the amounts remitted to them, are included in onboard and other revenues as concession revenues. All of these amounts are recognized on a completed voyage or pro rata basis as discussed above. Passenger ticket revenues include fees, taxes and charges collected by us from our guests. The fees, taxes and charges that vary with guest head counts and are directly imposed on a revenue-producing arrangement are expensed in commissions, transportation and other costs when the corresponding revenues are recognized. These fees, taxes and charges included in commissions, transportation and other costs were $438 million in 2022, $73 million in 2021 and $215 million in 2020. The remaining portion of fees, taxes and charges are expensed in other operating expenses when the corresponding revenues are recognized. Revenues and expenses from our hotel and transportation operations, which are included in our Tour and Other segment, are recognized at the time the services are performed. Customer Deposits Our payment terms generally require an initial deposit to confirm a reservation, with the balance due prior to the voyage. Cash received from guests in advance of the cruise is recorded in customer deposits and in other long-term liabilities on our Consolidated Balance Sheets. These amounts include refundable deposits. In certain situations, we have provided flexibility to guests by allowing guests to rebook at a future date, receive future cruise credits (“FCCs”) or elect to receive refunds in cash. We have at times issued enhanced FCCs. Enhanced FCCs provide the guest with an additional credit value above the original cash deposit received, and the enhanced value is recognized as a discount applied to the future cruise in the period used. We record a liability for unexpired FCCs to the extent we have received and not refunded cash from guests for cancelled bookings. We had total customer deposits of $5.1 billion and $3.5 billion as of November 30, 2022 and 2021, which includes approximately $210 million of unredeemed FCCs as of November 30, 2022. Given the uncertainty of travel demand caused by COVID-19 and lack of comparable historical experience of FCC redemptions, we are unable to estimate the number of FCCs that will not be used in future periods. Refunds payable to guests who have elected cash refunds are recorded in accounts payable. During 2022 and 2021, we recognized revenues of $1.9 billion and $0.1 billion related to our customer deposits as of November 30, 2021 and 2020. Historically, our customer deposits balance changes due to the seasonal nature of cash collections, the recognition of revenue, refunds of customer deposits and foreign currency changes. Contract Costs We recognize incremental travel agent commissions and credit and debit card fees incurred as a result of obtaining the ticket contract as assets when paid prior to the start of a voyage. We record these amounts within prepaid expenses and other and subsequently recognize these amounts as commissions, transportation and other at the time of revenue recognition or at the time of voyage cancellation. We had incremental costs of obtaining contracts with customers recognized as assets of $218 million and $55 million as of November 30, 2022 and 2021. Insurance We use a combination of insurance and self-insurance to cover a number of risks including illness and injury to crew, guest injuries, pollution, other third-party claims in connection with our cruise activities, damage to hull and machinery for each of our ships, war risks, workers’ compensation, directors’ and officers’ liability, property damage and general liability for shoreside third-party claims. We recognize insurance recoverables from third-party insurers up to the amount of recorded losses at the time the recovery is probable and upon settlement for amounts in excess of the recorded losses. All of our insurance policies are subject to coverage limits, exclusions and deductible levels. The liabilities associated with crew illnesses and crew and guest injury claims, including all legal costs, are estimated based on the specific merits of the individual claims or actuarially estimated based on historical claims experience, loss development factors and other assumptions. Selling and Administrative Expenses Selling expenses include a broad range of advertising, marketing and promotional expenses. Advertising is charged to expense as incurred, except for media production costs, which are expensed upon the first airing of the advertisement. Selling expenses totaled $744 million in 2022, $340 million in 2021 and $348 million in 2020. Administrative expenses represent the costs of our shoreside support, reservations and other administrative functions, and include salaries and related benefits, professional fees and building occupancy costs, which are typically expensed as incurred. Share-Based Compensation We recognize compensation expense for all share-based compensation awards using the fair value method. For time-based share awards, we recognize compensation cost ratably using the straight-line attribution method over the expected vesting period or to the retirement eligibility date, if earlier than the vesting period. For performance-based share awards, we estimate compensation cost based on the probability of the performance condition being achieved and recognize expense ratably using the straight-line attribution method over the expected vesting period. If all or a portion of the performance condition is not expected to be met, the appropriate amount of previously recognized compensation expense is reversed and future compensation expense is adjusted accordingly. For market-based share awards, we recognize compensation cost ratably using the straight-line attribution method over the expected vesting period. If the target market conditions are not expected to be met, compensation expense will still be recognized. We account for forfeitures as they occur. Earnings Per Share Basic earnings per share is computed by dividing net income (loss) by the weighted-average number of shares outstanding during each period. Diluted earnings per share is computed by dividing net income (loss) by the weighted-average number of shares and common stock equivalents outstanding during each period. For earnings per share purposes, Carnival Corporation common stock and Carnival plc ordinary shares are considered a single class of shares since they have equivalent rights. Accounting Pronouncements In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU No. 2020-04”), which provides temporary optional expedients and exceptions to accounting guidance on contract modifications and hedge accounting to ease entities’ financial reporting burdens as the market transitions from the London Interbank Offered Rate (“LIBOR”) and other interbank offered rates to alternative reference rates. ASU 2020-04 is effective upon issuance. In December 2022, the FASB deferred the date for which this guidance can be applied from December 31, 2022 to December 31, 2024. The use of LIBOR was phased out at the end of 2021, although the phase-out of U.S. dollar LIBOR for existing agreements has been delayed until June 2023. We continue to monitor developments related to the LIBOR transition and identification of an alternative, market-accepted rate. In December 2021, we amended our £350 million long-term debt agreement which referenced the British Pound sterling (“GBP”) LIBOR to the Sterling Overnight Index Average (“SONIA”) and applied the practical expedient. This amendment did not have a material impact on our consolidated financial statements. As of November 30, 2022, approximately $5.8 billion of our outstanding indebtedness bears interest at floating rates referenced to U.S. dollar LIBOR with maturity dates extending beyond June 30, 2023. We are currently evaluating our contracts referenced to U.S. dollar LIBOR and working with our creditors on updating credit agreements as necessary to include language regarding the successor or alternate rate to LIBOR. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements during the LIBOR transition period. The FASB issued guidance, Debt - Debt with Conversion and Other Options and Derivative and Hedging - Contracts in Entity’s Own Equity, which simplifies the accounting for convertible instruments. This guidance eliminates certain models that require separate accounting for embedded conversion features, in certain cases. Additionally, among other changes, the guidance eliminates certain of the conditions for equity classification for contracts in an entity’s own equity. The guidance also requires entities to use the if-converted method for all convertible instruments in the diluted earnings per share calculation and include the effect of share settlement for instruments that may be settled in cash or shares, except for certain liability-classified share-based payment awards. We will adopt this guidance in the first quarter of 2023 using the modified retrospective approach. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In September 2022, the FASB issued ASU No. 2022-04, Liabilities-Supplier Finance Programs (Subtopic 405-50) - Disclosure of Supplier Finance Program Obligations. This ASU requires that a buyer in a supplier finance program disclose sufficient information about the program to allow a user of financial statements to understand the program’s nature, activity during the period, changes from period to period, and potential magnitude. This ASU is expected to improve financial reporting by requiring new disclosures about the programs, thereby allowing financial statement users to better consider the effect of the programs on an entity’s working capital, liquidity, and cash flows. This ASU is effective for fiscal years beginning after December 15, 2022, except for the amendment on roll forward information which is effective for fiscal years beginning after December 15, 2023. We are currently evaluating the impact of the new guidance on the disclosures to our consolidated financial statements.

Equity Method Investments	Equity Method Investments We have a minority interest in Grand Bahama Shipyard Ltd. (“Grand Bahama”), a ship repair and maintenance facility. Grand Bahama provided services to us of $12 million in 2022, $11 million in 2021 and $38 million in 2020. As of November 30, 2022, our investment in Grand Bahama was $43 million, consisting of $10 million in equity and a loan of $33 million. As of November 30, 2021, our investment in Grand Bahama was $47 million, consisting of $14 million in equity and a loan of $33 million. We have a minority interest in the White Pass & Yukon Route (“White Pass”) that includes port, railroad and retail operations in Skagway, Alaska. White Pass provided an immaterial amount of services to us in 2022, 2021 and 2020. As a result of the effects of the pause and subsequent resumption of our guest cruise operations on the 2022 and 2021 Alaska seasons, we evaluated whether our investment in White Pass was other than temporarily impaired and performed impairment assessments. As a result of our assessments, we recognized impairment charges for 2022 and 2021 of $30 million and $17 million in other income (expense), net. As of November 30, 2022, our investment in White Pass was $50 million, consisting of $18 million in equity and a loan of $32 million.

(c) Amounts outstanding under our Revolving Facility were drawn in 2020 for an initial six-month term. We may continue to re-borrow or otherwise utilize available amounts under the Revolving Facility through August 2024, subject to satisfaction of the conditions in the facility. We had $2.6 billion available for borrowing under our Revolving Facility as of November 30, 2022. The Revolving Facility also includes an emissions linked margin adjustment whereby, after the initial applicable margin is set per the margin pricing grid, the margin may be adjusted based on performance in achieving certain agreed annual carbon emissions goals. We are required to pay a commitment fee on any unutilized portion. (d) As of November 30, 2022 the interest rate for the GBP unsecured loan was linked to SONIA and subject to a credit adjustment spread ranging from 0.03% to 0.28%. The referenced SONIA rate with the credit adjustment spread is subject to a 0% floor. As of November 30, 2021, this loan was referenced to GBP LIBOR. Carnival Corporation and/or Carnival plc is the primary obligor of all our outstanding debt excluding $0.5 billion under a term loan facility of Costa Crociere S.p.A. (“Costa”), a subsidiary of Carnival plc, and $2.0 billion of 2028 Senior Priority Notes (as defined below), issued by Carnival Holdings (Bermuda) Limited (“Carnival Holdings”), a subsidiary of Carnival Corporation. All our outstanding debt is issued or guaranteed by substantially the same entities with the exception of up to $250 million of the Costa term loan facility, which is guaranteed by certain subsidiaries of Carnival plc and Costa that do not guarantee our other outstanding debt, and our 2028 Senior Priority Notes, which are issued by Carnival Holdings, which does not guarantee our other outstanding debt. The scheduled maturities of our debt are as follows: (in millions) Year Principal Payments 2023 $ 2,396 2024 (a) 2,645 2025 4,385 2026 4,507 2027 5,662 Thereafter 16,020 Total $ 35,615 (a) Includes borrowings of $0.2 billion under our Revolving Facility. Amounts outstanding under our Revolving Facility were drawn in 2020 for an initial six-month term. We may continue to re-borrow or otherwise utilize available amounts under the Revolving Facility through August 2024, subject to satisfaction of the conditions in the facility. We had $2.6 billion available for borrowing under our Revolving Facility as of November 30, 2022. Short-Term Borrowings As of November 30, 2022 and November 30, 2021, our short-term borrowings consisted of $0.2 billion and $2.8 billion under our Revolving Facility. Secured Debt Repricing of 2025 Secured Term Loan In June 2021, we entered into an amendment to reprice our $2.8 billion 2025 Secured Term Loan (the “2025 Secured Term Loan”). The amended U.S. dollar tranche bears interest at a rate per annum equal to LIBOR (with a 0.75% floor) plus 3.0%. The amended euro tranche bears interest at a rate per annum equal to EURIBOR (with a 0% floor) plus 3.75%. 2028 Senior Secured Notes In July 2021, we issued $2.4 billion aggregate principal amount of 4.0% first-priority senior secured notes due in 2028 (the “2028 Senior Secured Notes”). We used the net proceeds from the issuance to purchase $2.0 billion aggregate principal amount of the 2023 Senior Secured Notes and to pay accrued interest on such notes and related fees and expenses. The 2028 Senior Secured Notes mature on August 1, 2028. 2028 Senior Secured Term Loan In October 2021, we borrowed an aggregate principal amount of $2.3 billion under a new term loan. We used the net proceeds from this borrowing to redeem the $2.0 billion outstanding aggregate principal amount of the 2023 Senior Secured Notes and to pay accrued interest on such notes and related fees and expenses. Borrowings under the new term loan bear interest at a rate per annum equal to LIBOR (with a 0.75% floor) plus 3.25% and mature on October 18, 2028. Unsecured Debt 2028 Senior Priority Notes In October 2022, Carnival Holdings issued an aggregate principal amount of $2.0 billion senior priority notes that mature on May 1, 2028 (the “2028 Senior Priority Notes”). The 2028 Senior Priority Notes bear interest at a rate of 10.4% per year and are callable beginning May 1, 2025. In connection with the offering of the 2028 Senior Priority Notes, Carnival Corporation, Carnival plc and their respective subsidiaries contributed 12 unencumbered vessels (the “Subject Vessels”) to Carnival Holdings, with each of the Subject Vessels continuing to be operated under one of Carnival Corporation’s, Carnival plc’s or one of their respective subsidiaries’ brands. As of November 30, 2022, the Subject Vessels had an aggregate net book value of approximately $8.3 billion. As of November 30, 2022, there was no change in the identity of the Subject Vessels. See “Collateral and Priority Pool” below. 2027 Senior Unsecured Notes In February 2021, we issued an aggregate principal amount of $3.5 billion senior unsecured notes that mature on March 1, 2027 (the “2027 Senior Unsecured Notes”). The 2027 Senior Unsecured Notes bear interest at a rate of 5.8% per year. 2029 Senior Unsecured Notes In November 2021, we issued an aggregate principal amount of $2.0 billion senior unsecured notes that mature on May 1, 2029 (the “2029 Senior Unsecured Notes”), intended to refinance various 2022 and other debt maturities. The 2029 Senior Unsecured Notes bear interest at a rate of 6.0% per year and are callable beginning November 1, 2024. 2030 Senior Unsecured Notes In May 2022, we issued an aggregate principal amount of $1.0 billion senior unsecured notes that mature on June 1, 2030 (the “2030 Senior Unsecured Notes”). The 2030 Senior Unsecured Notes bear interest at a rate of 10.5% per year and are callable beginning June 1, 2025. Export Credit Facility Borrowings During the year ended November 30, 2022, we borrowed $3.1 billion under export credit facilities due in semi-annual installments through 2034. As of November 30, 2022, the net book value of the vessels subject to negative pledges was $14.2 billion. Debt Holidays In 2021, we amended substantially all of our export credit facilities to defer approximately $1.0 billion of principal payments that would otherwise have been due over a period commencing April 1, 2021 until May 31, 2022, with repayments to be made over the following five years. The cumulative deferred principal amount of the debt holiday amendments, inclusive of the amendments entered into in 2020, is approximately $1.2 billion as of November 30, 2022. In addition, these amendments aligned the financial covenants of all our export credit facilities with our other facilities. Convertible Notes In 2020, we issued $2.0 billion aggregate principal amount of 5.8% convertible senior notes due 2023 (the “2023 Convertible Notes”). The 2023 Convertible Notes mature on April 1, 2023, unless earlier repurchased or redeemed by us or earlier converted in accordance with their terms prior to the maturity date. Since April 2020, we repurchased, exchanged and converted a portion of the 2023 Convertible Notes which resulted in a decrease of the principal amount of the 2023 Convertible Notes to $0.1 billion. In August 2022, we issued $339 million aggregate principal amount of 5.8% convertible senior notes due 2024 (the “2024 Convertible Notes”) pursuant to privately-negotiated non-cash exchange agreements with certain holders of the 2023 Convertible Notes, pursuant to which such holders agreed to exchange their 2023 Convertible Notes for an equal amount of 2024 Convertible Notes. In November 2022, we issued an additional $87 million aggregate principal amount of the 2024 Convertible Notes pursuant to privately-negotiated non-cash exchange agreements with certain holders of the 2023 Convertible Notes, pursuant to which such holders agreed to exchange their 2023 Convertible Notes for an equal amount of additional 2024 Convertible Notes. The 2024 Convertible Notes mature on October 1, 2024, unless earlier repurchased or redeemed by us or earlier converted in accordance with their terms prior to the maturity date. In November 2022, we issued $1.1 billion aggregate principal amount of 5.8% convertible senior notes due 2027 (the “2027 Convertible Notes” and, together with the 2023 Convertible Notes and the 2024 Convertible Notes, the “Convertible Notes”). The 2027 Convertible Notes mature on December 1, 2027, unless earlier repurchased or redeemed by us or earlier converted in accordance with their terms prior to the maturity date. The Convertible Notes are convertible by holders, subject to the conditions described within the respective indentures that govern the Convertible Notes, into cash, shares of Carnival Corporation common stock, or a combination thereof, at our election. The 2023 Convertible Notes and the 2024 Convertible Notes each have an initial conversion rate of 100 shares of Carnival Corporation common stock per $1,000 principal amount of notes, equivalent to an initial conversion price of $10 per share of common stock. The 2027 Convertible Notes have an initial conversion rate of approximately 75 shares of Carnival Corporation common stock per $1,000 principal amount of notes, equivalent to an initial conversion price of approximately $13.39 per share of common stock. The initial conversion price of the Convertible Notes is subject to certain anti-dilutive adjustments and may also increase if such Convertible Notes are converted in connection with a tax redemption or certain corporate events as described within the respective indentures that govern the Convertible Notes. The 2024 Convertible Notes were convertible from the date of issuance of the 2024 Convertible Notes until August 31, 2022, and thereafter may become convertible if certain conditions are met. As of November 30, 2022, there were no conditions satisfied which would allow the holders of the 2023 Convertible Notes, the 2024 Convertible Notes or the 2027 Convertible Notes to convert and therefore the Convertible Notes were not convertible as of such date. Refer to Note 15 - “Supplemental Cash Flow Information” for additional detail on transactions related to the Convertible Notes. The 2023 Convertible Notes were redeemable, in whole but not in part, at any time on or prior to December 31, 2022 at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest to the redemption date, if we or any guarantor would have to pay any additional amounts on the 2023 Convertible Notes due to a change in tax laws, regulations or rulings or a change in the official application, administration or interpretation thereof. We may redeem the 2024 Convertible Notes, in whole but not in part, at any time on or prior to June 30, 2024 at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest to the redemption date, if we or any guarantor would have to pay any additional amounts on the 2024 Convertible Notes due to a change in tax laws, regulations or rulings or a change in the official application, administration or interpretation thereof. We may redeem the 2027 Convertible Notes, in whole but not in part, at any time on or prior to the 40th scheduled trading day immediately before the maturity date at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest to the redemption date, if we or any guarantor would have to pay any additional amounts on the 2027 Convertible Notes due to a change in tax laws, regulations or rulings or a change in the official application, administration or interpretation thereof. On or after December 5, 2025 and on or before the 40th scheduled trading day immediately before the maturity date, we may redeem for cash all or part of the 2027 Convertible Notes, at our option, if the last reported sale price of Carnival Corporation’s common stock exceeds 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which we provide notice of redemption, during the 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption. The redemption price will equal 100% of the principal amount of the 2027 Convertible Notes being redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. We account for the Convertible Notes as separate liability and equity components. We determine the carrying amount of the liability component as the present value of its cash flows. The carrying amount of the equity component representing the conversion option is calculated by deducting the carrying value of the liability component from the initial proceeds of the Convertible Notes. The carrying amount of the equity component was $229 million on the date of issuance of the 2027 Convertible Notes and $286 million on the date of issuance of the 2023 Convertible Notes. The carrying amount of the equity component for the 2023 Convertible Notes was reduced to zero in conjunction with the partial repurchase in August 2020 because at the time of repurchase, the fair value of the equity component for the portion of the 2023 Convertible Notes that was repurchased, exceeded the total amount of the equity component recorded at the time the 2023 Convertible Notes were issued. The fair value of the conversion option remained unchanged after the exchange of the portion of the 2023 Convertible Notes for the 2024 Convertible Notes and, as a result, there was no adjustment to the carrying amount of the equity component. The debt discount, which represents the excess of the principal amount of the Convertible Notes over the carrying amount of the liability component on the date of issuance of the Convertible Notes, is capitalized and amortized to interest expense under the effective interest rate method over the term of the respective Convertible Notes. Following the exchange of the portion of the 2023 Convertible Notes for the 2024 Convertible Notes, the remaining unamortized discount was allocated between the 2023 Convertible Notes and the 2024 Convertible Notes and is amortized to interest expense over each respective term using the effective interest rate method. The net carrying value of the liability component of the Convertible Notes was as follows: November 30, (in millions) 2022 2021 Principal $ 1,653 $ 522 Less: Unamortized debt discount (274) (45) $ 1,380 $ 478 As of November 30, 2022, the if-converted value on available shares of 137 million for the Convertible Notes was below par. Collateral and Priority Pool As of November 30, 2022, the net book value of our ships and ship improvements, excluding ships under construction, is $36.2 billion. Our secured debt is secured on either a first or second-priority basis, depending on the instrument, by certain collateral, which includes vessels and certain assets related to those vessels and material intellectual property (combined net book value of approximately $23.6 billion, including $22.0 billion related to vessels and certain assets related to those vessels) as of November 30, 2022 and certain other assets. In addition, as of December 9, 2022, $8.3 billion in net book value of our ships and ship improvements have been transferred to Carnival Holdings. These vessels are included in the Vessel Priority Pool of Subject Vessels for our 2028 Senior Priority Notes. Covenant Compliance As of November 30, 2022, our Revolving Facility, unsecured loans and export credit facilities contain certain covenants listed below. • Maintain minimum interest coverage (adjusted EBITDA to consolidated net interest charges, as defined in the agreements) (the “Interest Coverage Covenant”) at the end of each fiscal quarter from August 31, 2023, at a ratio of not less than 2.0 to 1.0 for the August 31, 2023 testing date, 2.5 to 1.0 for the November 30, 2023 testing date, and 3.0 to 1.0 for the February 29, 2024 testing date onwards, or through their respective maturity dates. • Maintain minimum issued capital and consolidated reserves (as defined in the agreements) of $5.0 billion • Limit our debt to capital (as defined in the agreements) percentage from the November 30, 2021 testing date until the May 31, 2023 testing date, to a percentage not to exceed 75%, following which it will be tested at levels which decline ratably to 65% from the May 31, 2024 testing date onwards • Maintain minimum liquidity of $1.5 billion through November 30, 2026 • Adhere to certain restrictive covenants through November 30, 2024 • Limit the amounts of our secured assets as well as secured and other indebtedness During 2022, we entered into letter agreements to waive compliance with the Interest Coverage Covenant under our Revolving Facility and $11.8 billion of $12.1 billion of our unsecured loans and export credit facilities which contain this covenant through the February 29, 2024 testing date. Subsequent to November 30, 2022 and as of January 12, 2023, we entered into further letter agreements to waive compliance with the Interest Coverage Covenant under the remaining $0.3 billion of our unsecured loans and export credit facilities which contain the covenant through the February 29, 2024 testing date and our Revolving Facility through the May 31, 2024 testing date. We will be required to comply beginning with the next testing date of May 31, 2024 or August 31, 2024, as applicable. At November 30, 2022, we were in compliance with the applicable covenants under our debt agreements. Generally, if an event of default under any debt agreement occurs, then, pursuant to cross-default and/or cross-acceleration clauses therein, substantially all of our outstanding debt and derivative contract payables could become due, and our debt and derivative contracts could be terminated. Any financial covenant amendment may lead to increased costs, increased interest rates, additional restrictive covenants and other available lender protections that would be applicable. Carnival Corporation or Carnival plc and certain of our subsidiaries have guaranteed substantially all of our indebtedness.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Litigation We are routinely involved in legal proceedings, claims, disputes, regulatory matters and governmental inspections or investigations arising in the ordinary course of or incidental to our business, including those noted below. Additionally, as a result of the impact of COVID-19, litigation claims, enforcement actions, regulatory actions and investigations, including, but not limited to, those arising from personal injury and loss of life, have been and may, in the future, be asserted against us. We expect many of these claims and actions, or any settlement of these claims and actions, to be covered by insurance and historically the maximum amount of our liability, net of any insurance recoverables, has been limited to our self-insurance retention levels. We record provisions in the consolidated financial statements for pending litigation when we determine that an unfavorable outcome is probable and the amount of the loss can be reasonably estimated. Legal proceedings and government investigations are subject to inherent uncertainties, and unfavorable rulings or other events could occur. Unfavorable resolutions could involve substantial monetary damages. In addition, in matters for which conduct remedies are sought, unfavorable resolutions could include an injunction or other order prohibiting us from selling one or more products at all or in particular ways, precluding particular business practices or requiring other remedies. An unfavorable outcome might result in a material adverse impact on our business, results of operations, financial position or liquidity. As previously disclosed, on May 2, 2019, two lawsuits were filed against Carnival Corporation in the U.S. District Court for the Southern District of Florida under Title III of the Cuban Liberty and Democratic Solidarity Act, also known as the Helms- Burton Act, alleging that Carnival Corporation “trafficked” in confiscated Cuban property when certain ships docked at certain ports in Cuba, and that this alleged “trafficking” entitles the plaintiffs to treble damages. In the matter filed by Havana Docks Corporation, the hearings on motions for summary judgment were concluded on January 18, 2022. On March 21, 2022, the court granted summary judgment in favor of Havana Docks Corporation as to liability. On August 31, 2022, the court determined that the trebling provision of the Helms-Burton statute applies to damages and interest and accordingly, we adjusted our estimated liability for this matter. The court held a status conference on September 22, 2022, at which time it was determined that a jury trial is no longer necessary. On December 30, 2022, the court entered judgment against Carnival in the amount of $110 million plus $4 million in fees and costs. We intend to appeal. In the matter filed by Javier Bengochea on December 20, 2021, the court issued an order inviting an amicus brief from the U.S. government on several issues involved in the appeal. The U.S. government filed its brief and the court ordered the parties to respond. On May 6, 2022 we filed our response brief. On November 23, 2022, the Eleventh Circuit entered an order affirming the dismissal of the case in our favor. We believe that any final liability which may arise as a result of these actions is unlikely to have a material impact on our consolidated financial statements. As previously disclosed, on April 8, 2020, DeCurtis LLC (“DeCurtis”), a former vendor, filed an action against Carnival Corporation in the U.S. District Court for the Middle District of Florida seeking declaratory relief that DeCurtis is not infringing on several of Carnival Corporation’s patents in relation to its OCEAN Medallion systems and technology. The action also raises certain monopolization claims under The Sherman Antitrust Act of 1890, unfair competition and tortious interference, and seeks declaratory judgment that certain Carnival Corporation patents are unenforceable. DeCurtis seeks damages, including its fees and costs, and seeks declarations that it is not infringing and/or that Carnival Corporation’s patents are unenforceable. On April 10, 2020, Carnival Corporation filed an action against DeCurtis in the U.S. District Court for the Southern District of Florida for breach of contract, trade secrets violations and patent infringement. Carnival Corporation seeks damages, including its fees and costs, as well as an order permanently enjoining DeCurtis from engaging in such activities. These two cases have now been consolidated in the Southern District of Florida. On April 25, 2022, we moved for summary judgment on our breach of contract claims and on all of DeCurtis’s claims. DeCurtis also filed a motion for summary judgment on certain portions of our claims. Both motions for summary judgment were fully briefed. On July 28, 2022, the court adopted the Magistrate Judge’s report and recommendation granting our opening claim construction brief and denying DeCurtis’s motion for summary judgment regarding the invalidity of various patent claims. On November 11, 2022, the Magistrate Judge entered a Report and Recommendation which recommended that the Court enter an order denying our motion for summary judgment and granting in part and denying in part DeCurtis’s motion for summary judgment. Both parties have filed objections to the Report and Recommendation. The court has set the trial date for February 27, 2023. We believe the ultimate outcome will not have a material impact on our consolidated financial statements. COVID-19 Actions We have been named in a number of individual actions related to COVID-19. These actions include tort claims based on a variety of theories, including negligence and failure to warn. The plaintiffs in these actions allege a variety of injuries: some plaintiffs confined their claim to emotional distress, while others allege injuries arising from testing positive for COVID-19. A smaller number of actions include wrongful death claims. Substantially all of these individual actions have now been dismissed or settled for immaterial amounts. As of November 30, 2022, 11 purported class actions have been brought by former guests in several U.S. federal courts, the Federal Court in Australia, and in Italy. These actions include tort claims based on a variety of theories, including negligence, gross negligence and failure to warn, physical injuries and severe emotional distress associated with being exposed to and/or contracting COVID-19 onboard. As of November 30, 2022, nine of these class actions have either been settled individually for immaterial amounts or had their class allegations dismissed by the courts and only the Australian and Italian matters remain. All COVID-19 matters seek monetary damages and most seek additional punitive damages in unspecified amounts. We continue to take actions to defend against the above claims. Regulatory or Governmental Inquiries and Investigations We have been, and may continue to be, impacted by breaches in data security and lapses in data privacy, which occur from time to time. These can vary in scope and intent from inadvertent events to malicious motivated attacks. As previously disclosed, on June 24, 2022, we finalized a settlement with the New York Department of Financial Services (“NY DFS”) in connection with previously disclosed cybersecurity events, pursuant to which we have paid an amount that did not have a material impact on our consolidated financial statements. In addition, as previously disclosed, we finalized a settlement with the State Attorneys General from 46 states in connection with the same cybersecurity events, pursuant to which we have paid an amount that did not have a material impact on our consolidated financial statements. All previously disclosed cyber incidents have now been resolved. We have incurred legal and other costs in connection with cyber incidents that have impacted us. The penalties and settlements paid in connection with cyber incidents over the last three years were not material. While these incidents did not have a material adverse effect on our business, results of operations, financial position or liquidity, no assurances can be given about the future and we may be subject to future litigation, attacks or incidents that could have such a material adverse effect. On March 14, 2022, the U.S. Department of Justice and the U.S. Environmental Protection Agency notified us of potential civil penalties and injunctive relief for alleged Clean Water Act violations by owned and operated vessels covered by the 2013 Vessel General Permit. We are working with these agencies to reach a resolution of this matter. We believe the ultimate outcome will not have a material impact on our consolidated financial statements. Other Contingent Obligations Some of the debt contracts we enter into include indemnification provisions obligating us to make payments to the counterparty if certain events occur. These contingencies generally relate to changes in taxes or changes in laws which increase the lender’s costs. There are no stated or notional amounts included in the indemnification clauses, and we are not able to estimate the maximum potential amount of future payments, if any, under these indemnification clauses.

Taxation

Income Tax Disclosure [Abstract]
Taxation	Taxation A summary of our principal taxes and exemptions in the jurisdictions where our significant operations are located is as follows: U.S. Income Tax We are primarily foreign corporations engaged in the business of operating cruise ships in international transportation. We also own and operate, among other businesses, the U.S. hotel and transportation business of Holland America Princess Alaska Tours through U.S. corporations. Our North American cruise ship businesses and certain ship-owning subsidiaries are engaged in a trade or business within the U.S. Depending on its itinerary, any particular ship may generate income from sources within the U.S. We believe that our U.S. source income and the income of our ship-owning subsidiaries, to the extent derived from, or incidental to, the international operation of a ship or ships, is currently exempt from U.S. federal income and branch profit taxes. Our domestic U.S. operations, principally the hotel and transportation business of Holland America Princess Alaska Tours, are subject to federal and state income taxation in the U.S. In general, under Section 883 of the Internal Revenue Code, certain non-U.S. corporations (such as our North American cruise ship businesses) are not subject to U.S. federal income tax or branch profits tax on U.S. source income derived from, or incidental to, the international operation of a ship or ships. Applicable U.S. Treasury regulations provide in general that a foreign corporation will qualify for the benefits of Section 883 if, in relevant part, (i) the foreign country in which the foreign corporation is organized grants an equivalent exemption to corporations organized in the U.S. in respect of each category of shipping income for which an exemption is being claimed under Section 883 (an “equivalent exemption jurisdiction”) and (ii) the foreign corporation meets a defined publicly-traded corporation stock ownership test (the “publicly-traded test”). Subsidiaries of foreign corporations that are organized in an equivalent exemption jurisdiction and meet the publicly-traded test also benefit from Section 883. We believe that Panama is an equivalent exemption jurisdiction and that Carnival Corporation currently satisfies the publicly-traded test under the regulations. Accordingly, substantially all of Carnival Corporation’s income is exempt from U.S. federal income and branch profit taxes. Regulations under Section 883 list certain activities that the IRS does not consider to be incidental to the international operation of ships and, therefore, the income attributable to such activities, to the extent such income is U.S. source, does not qualify for the Section 883 exemption. Among the activities identified as not incidental are income from the sale of air transportation, transfers, shore excursions and pre- and post-cruise land packages to the extent earned from sources within the U.S. We believe that the U.S. source transportation income earned by Carnival plc and its subsidiaries currently qualifies for exemption from U.S. federal income tax under applicable bilateral U.S. income tax treaties. Carnival Corporation, Carnival plc and certain subsidiaries are subject to various U.S. state income taxes generally imposed on each state’s portion of the U.S. source income subject to U.S. federal income taxes. However, the state of Alaska imposes an income tax on its allocated portion of the total income of our companies doing business in Alaska and certain of their subsidiaries. UK and Australian Income Tax Cunard, P&O Cruises (UK) and P&O Cruises (Australia) are divisions of Carnival plc and have elected to enter UK tonnage tax under a rolling ten-year term and, accordingly, reapply every year. Companies to which the tonnage tax regime applies pay corporation taxes on profits calculated by reference to the net tonnage of qualifying ships. UK corporation tax is not chargeable under the normal UK tax rules on these brands’ relevant shipping income. Relevant shipping income includes income from the operation of qualifying ships and from shipping related activities. For a company to be eligible for the regime, it must be subject to UK corporation tax and, among other matters, operate qualifying ships that are strategically and commercially managed in the UK. Companies within UK tonnage tax are also subject to a seafarer training requirement. Our UK non-shipping activities that do not qualify under the UK tonnage tax regime remain subject to normal UK corporation tax. P&O Cruises (Australia) and all of the other cruise ships operated internationally by Carnival plc for the cruise segment of the Australian vacation region are exempt from Australian corporation tax by virtue of the UK/Australian income tax treaty. Italian and German Income Tax In 2015, Costa and AIDA re-elected to enter the Italian tonnage tax regime through 2024 and can reapply for an additional ten Most of Costa’s and AIDA’s earnings that are not eligible for taxation under the Italian tonnage tax regime will be taxed at an effective tax rate of 4.8% in 2022 and 2021. Substantially all of AIDA’s earnings are exempt from German income taxes by virtue of the Germany/Italy income tax treaty. Other We recognize income tax provisions for uncertain tax positions, based solely on their technical merits, when it is more likely than not to be sustained upon examination by the relevant tax authority. The tax benefit to be recognized is measured as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate resolution. Based on all known facts and circumstances and current tax law, we believe that the total amount of our uncertain income tax position liabilities and related accrued interest are not material to our financial position. All interest expense related to income tax liabilities is included in income tax expense.

Equity [Abstract]
Shareholders' Equity	Shareholders’ Equity Carnival Corporation’s Articles of Incorporation authorize its Boards of Directors, at its discretion, to issue up to 40 million shares of preferred stock. At November 30, 2022 and 2021, no Carnival Corporation preferred stock or Carnival plc preference shares had been issued. Share Repurchase Program Under a share repurchase program effective 2004, we had been authorized to repurchase Carnival Corporation common stock and Carnival plc ordinary shares (the “Repurchase Program”). On June 15, 2020, to enhance our liquidity and comply with restrictions in our recent financing transactions, the Boards of Directors terminated the Repurchase Program.

Fair Value Disclosures [Abstract]
Fair Value Measurements, Derivative Instruments and Hedging Activities and Financial Risks	Fair Value Measurements, Derivative Instruments and Hedging Activities and Financial Risks Fair Value Measurements Fair value is defined as the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and is measured using inputs in one of the following three categories: • Level 1 measurements are based on unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access. Valuation of these items does not entail a significant amount of judgment. • Level 2 measurements are based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active or market data other than quoted prices that are observable for the assets or liabilities. • Level 3 measurements are based on unobservable data that are supported by little or no market activity and are significant to the fair value of the assets or liabilities.

Nonfinancial Instruments that are Measured at Fair Value on a Nonrecurring Basis Valuation of Goodwill and Trademarks As of July 31, 2022, we performed our annual goodwill and trademark impairment reviews and determined there was no impairment for goodwill and trademarks at our annual test date. During 2021 and as a result of the continued resumption of guest cruise operations, ongoing impacts of COVID-19 and its effect on our expected future operating cash flows, including changes in estimates related to the timing of our full return to guest cruise operations and improved profitability, we performed interim discounted cash flow analyses for our EA segment reporting units and determined their estimated fair values no longer exceeded their carrying values. As a result, we recognized goodwill impairment charges of $226 million and accordingly have no remaining goodwill for those reporting units. During 2020, we performed interim discounted cash flow analyses for certain reporting units with goodwill as of February 29, 2020 and for all reporting units with goodwill or trademarks as of May 31, 2020 and recognized goodwill impairment charges of $2.1 billion. As of July 31, 2020, we performed our annual goodwill and trademark impairment reviews and we determined there was no incremental impairment for goodwill or trademarks. The determination of the fair value of our reporting units’ goodwill and trademarks includes numerous estimates and underlying assumptions that are subject to various risks and uncertainties. The effect of the pause and subsequent resumption of guest cruise operations has created additional uncertainty in forecasting the operating results and future cash flows used in our impairment analyses. We believe that we have made reasonable estimates and judgments. The assumptions, all of which are considered Level 3 inputs, used in our 2021 cash flow analyses and which resulted in goodwill impairments for all but one reporting unit consisted of: • The timing and pace of our full return to guest cruise operations • Weighted-average cost of capital of market participants, adjusted for the risk attributable to the geographic regions in which these cruise brands operate (“WACC”) The assumptions, all of which are considered Level 3 inputs, used in our 2020 cash flow analyses consisted of: • The timing of our return to service, changes in market conditions and port or other restrictions • Forecasted revenues net of our most significant variable costs, which are travel agent commissions, costs of air and other transportation, and certain other costs that are directly associated with onboard and other revenues including credit and debit card fees • The allocation of new ships and the timing of the transfer or sale of ships amongst brands, as well as the estimated proceeds from ship sales • WACC The estimated fair value of the reporting unit with remaining goodwill and of our trademarks significantly exceeded their carrying value as of the date of the most recent impairment test.

As a result of the continued effects of COVID-19 on our business and certain Asia markets which remain closed to cruising (particularly China), and our updated expectations for our deployment, we determined that two ships had net carrying values that exceeded their respective estimated undiscounted future cash flows. We then estimated the fair value of these ships, based on their estimated selling values, and recognized ship impairment charges as summarized in the table below. We performed undiscounted cash flow analyses on certain ships throughout 2021 and 2020 and determined that certain ships had net carrying values that exceeded their estimated undiscounted future cash flows and fair values, and, as a result, we recognized ship impairment charges during 2021 and 2020. We believe we have made reasonable estimates and judgments as part of our assessments. A change in the principal judgments or estimates may result in a need to perform additional impairment reviews. In 2022, the principal assumption used in determining the fair value of these ships were the estimated sales proceeds, which are considered a Level 3 input. In 2021, the principal assumptions used in determining the fair value of these ships were the timing of the sale of ships and estimated proceeds, which are considered Level 3 inputs. In 2020, the principal assumptions used in determining the fair value of these ships consisted of: • Timing of the respective ship’s return to service, changes in market conditions and port or other restrictions • Forecasted ship revenues net of our most significant variable costs, which are travel agent commissions, costs of air and other transportation and certain other costs that are directly associated with onboard and other revenues, including credit and debit card fees • Timing of the sale of ships and estimated proceeds The impairment charges summarized in the table below are included in ship and other impairments in our Consolidated Statements of Income (Loss).

(b) We have interest rate swaps designated as cash flow hedges whereby we receive floating interest rate payments in exchange for making fixed interest rate payments. These interest rate swap agreements effectively changed $89 million at November 30, 2022 and $160 million at November 30, 2021 of EURIBOR-based floating rate euro debt to fixed rate euro debt. At November 30, 2022, these interest rate swaps settle through 2025. Our derivative contracts include rights of offset with our counterparties.

Substantially all of our exposure to market risk for changes in fuel prices relates to the consumption of fuel on our ships. We manage fuel consumption through ship maintenance practices, modifying our itineraries and implementing innovative technologies. Foreign Currency Exchange Rate Risks Overall Strategy We manage our exposure to fluctuations in foreign currency exchange rates through our normal operating and financing activities, including netting certain exposures to take advantage of any natural offsets and, when considered appropriate, through the use of derivative and non-derivative financial instruments. Our primary focus is to monitor our exposure to, and manage, the economic foreign currency exchange risks faced by our operations and realized if we exchange one currency for another. We consider hedging certain of our ship commitments and net investments in foreign operations. The financial impacts of our hedging instruments generally offset the changes in the underlying exposures being hedged. Operational Currency Risks Our operations primarily utilize the U.S. dollar, Euro, Sterling or the Australian dollar as their functional currencies. Our operations also have revenue and expenses denominated in non-functional currencies. Movements in foreign currency exchange rates affect our financial statements. Investment Currency Risks We consider our investments in foreign operations to be denominated in stable currencies and of a long-term nature. We partially mitigate the currency exposure of our investments in foreign operations by designating a portion of our foreign currency debt and derivatives as hedges of these investments. As of November 30, 2022, we have designated $419 million of our sterling-denominated debt as non-derivative hedges of our net investments in foreign operations. In 2022, we recognized $48 million of gains on these non-derivative net investment hedges in the cumulative translation adjustment section of other comprehensive income (loss). We also have euro-denominated debt which provides an economic offset for our operations with euro functional currency. Newbuild Currency Risks Our shipbuilding contracts are typically denominated in euros. Our decision to hedge a non-functional currency ship commitment for our cruise brands is made on a case-by-case basis, considering the amount and duration of the exposure, market volatility, economic trends, our overall expected net cash flows by currency and other offsetting risks. At November 30, 2022, our remaining newbuild currency exchange rate risk primarily relates to euro-denominated newbuild contract payments for non-euro functional currency brands, which represent a total unhedged commitment of $4.4 billion for newbuilds scheduled to be delivered through 2025. The cost of shipbuilding orders that we may place in the future that are denominated in a different currency than our cruise brands’ will be affected by foreign currency exchange rate fluctuations. These foreign currency exchange rate fluctuations may affect our decision to order new cruise ships. Interest Rate Risks Concentrations of Credit Risk As part of our ongoing control procedures, we monitor concentrations of credit risk associated with financial and other institutions with which we conduct significant business. We seek to manage these credit risk exposures, including counterparty nonperformance primarily associated with our cash equivalents, investments, notes receivables, reserve funds related to customer deposits, future financing facilities, contingent obligations, derivative instruments, insurance contracts, long-term ship charters and new ship progress payment guarantees, by: • Conducting business with well-established financial institutions, insurance companies and export credit agencies • Diversifying our counterparties • Having guidelines regarding credit ratings and investment maturities that we follow to help safeguard liquidity and minimize risk • Generally requiring collateral and/or guarantees to support notes receivable on significant asset sales, long-term ship charters and new ship progress payments to shipyards At November 30, 2022, our exposures under derivative instruments were not material. We also monitor the creditworthiness of travel agencies and tour operators in Australia and Europe and credit and debit card providers to which we extend credit in the normal course of our business. Concentrations of credit risk associated with trade receivables and other receivables, charter-hire agreements and contingent obligations are not considered to be material, principally due to the large number of unrelated accounts, the nature of these contingent obligations and their short maturities. Normally, we have not required collateral or other security to support normal credit sales. Historically, we have not experienced significant credit losses, including counterparty nonperformance; however, because of the continued effects the pandemic is having on economies, we have experienced, and may continue to experience, an increase in credit losses.

These costs are recorded within Commissions, transportation and other in our Consolidated Statements of Income (Loss). Variable and short-term lease costs related to operating leases, other than the port facilities, were not material to our consolidated financial statements. (b) Several of our preferential berthing agreements have force majeure provisions which were in effect during the pause in guest cruise operations due to COVID-19. The cash outflow for leases was materially consistent with the lease expense recognized during 2022. During 2022, we obtained $111 million of right-of-use assets in exchange for new operating lease liabilities.

Retirement Benefits [Abstract]
Compensation Plans and Post-Employment Benefits	Compensation Plans and Post-Employment Benefits Equity Plans We issue our share-based compensation awards, which at November 30, 2022 included time-based share awards (restricted stock awards and restricted stock units), performance-based share awards and market-based share awards (collectively “equity awards”), under the Carnival Corporation and Carnival plc stock plans. Equity awards are principally granted to management level employees and members of our Boards of Directors. The plans are administered by the Compensation Committees which are made up of independent directors who determine which employees are eligible to participate, the monetary value or number of shares for which equity awards are to be granted and the amounts that may be exercised or sold within a specified term. We had an aggregate of 16.7 million shares available for future grant at November 30, 2022. We fulfill our equity award obligations using shares purchased in the open market or with unissued or treasury shares. Our equity awards generally vest over a three-year period, subject to earlier vesting under certain conditions.

Single-employer Defined Benefit Pension Plans We maintain several single-employer defined benefit pension plans, which cover certain of our shipboard and shoreside employees. The U.S. and UK shoreside employee plans are closed to new membership and are funded at or above the level required by U.S. or UK regulations. The remaining defined benefit plans are primarily unfunded. These plans provide pension benefits primarily based on employee compensation and years of service.

The discount rate used to determine the UK Plan’s future net periodic benefit cost was determined as the equivalent rate based on applying each individual spot rate from a yield curve determined from AA credit rated bonds at the balance sheet date for each year’s cash flow. The UK Plan’s expected long-term return on plan assets is consistent with the long-term investment return target provided to the UK Plan’s fiduciary manager (U.K. government fixed interest bonds (gilts) plus 1.0% and was 4.3% per annum as of November 30, 2022.

The investment policy for each plan specifies the type of investment vehicles appropriate for the plan, asset allocation guidelines, criteria for selection of investment managers and procedures to monitor overall investment performance, as well as investment manager performance. As of November 30, 2022 and 2021, respectively, the All Other Plans were unfunded. The fair values of the plan assets of the UK Plan by investment class are as follows: November 30, 2022 2021 Equities $ 53 $ 62 U.K. government fixed interest bonds (gilts) $ 169 $ 283 Multiemployer Defined Benefit Pension Plans We participate in two multiemployer defined benefit pension plans in the UK, the British Merchant Navy Officers Pension Fund (registration number 10005645) (“MNOPF”), which is divided into two sections, the “New Section” and the “Old Section,” and the British Merchant Navy Ratings Pension Fund (registration number 10005646) (“MNRPF”). Collectively, we refer to these as “the multiemployer plans.” The multiemployer plans are maintained for the benefit of the employees of the participating employers who make contributions to the plans. The risks of participating in these multiemployer plans are different from single-employer plans, including: • Contributions made by employers, including us, may be used to provide benefits to employees of other participating employers • If any of the participating employers were to withdraw from the multiemployer plans or fail to make their required contributions, any unfunded obligations would be the responsibility of the remaining participating employers. We are contractually obligated to make all required contributions as determined by the plans’ trustees. All of our multiemployer plans are closed to new membership and future benefit accrual. The MNOPF Old Section is fully funded. We expense our portion of the MNOPF New Section deficit as amounts are invoiced by, and become due and payable to, the trustees. We accrue and expense our portion of the MNRPF deficit based on our estimated probable obligation from the most recent actuarial review. Total expense for the multiemployer plans was $2 million in 2022, $28 million in 2021 and $2 million in 2020. Based on the most recent valuation at March 31, 2021 of the MNOPF New Section, it was determined that this plan was 102% funded. In 2022, 2021 and 2020, our contributions to the MNOPF New Section did not exceed 5% of total contributions to the fund. Based on the most recent valuation at March 31, 2020 of the MNRPF, it was determined that this plan was 93% funded. In 2022, 2021 and 2020, our contributions to the MNRPF did not exceed 5% of total contributions to the fund. It is possible that we will be required to fund and expense additional amounts for the multiemployer plans in the future; however, such amounts are not expected to be material to our consolidated financial statements. Defined Contribution Plans We have several defined contribution plans available to most of our employees. We contribute to these plans based on employee contributions, salary levels and length of service. Total expense for these plans was $40 million in 2022, $35 million in 2021 and $24 million in 2020.

In August 2022, we issued $339 million aggregate principal amount of 2024 Convertible Notes pursuant to privately-negotiated non-cash exchange agreements with certain holders of the 2023 Convertible Notes, pursuant to which such holders agreed to exchange their 2023 Convertible Notes for an equal amount of 2024 Convertible Notes. In November 2022, we issued an additional $87 million aggregate principal amount of the 2024 Convertible Notes pursuant to privately-negotiated non-cash exchange agreements with certain holders of the 2023 Convertible Notes, pursuant to which such holders agreed to exchange their 2023 Convertible Notes for an equal amount of additional 2024 Convertible Notes. In addition, in August and November 2020, in connection with the repurchase of the 2023 Convertible Notes, as part of registered direct offerings of Carnival Corporation common stock used to repurchase a portion of the 2023 Convertible Notes, as an administrative convenience, we permitted the purchasers of 151.2 million shares of Carnival Corporation common stock to offset the purchase price payable to us against our obligation to pay the purchase price for $1.3 billion aggregate principal amount of the 2023 Convertible Notes held by them, which is reflected as a non-cash transaction for the year ended November 30, 2020. Refer to Note 5 - “Debt” for additional detail relating to our 2028 Senior Priority Notes and the 2024 Convertible Notes. For the years ended November 30, 2022 and 2021, we did not have borrowings or repayments of commercial paper with original maturities greater than three months. For the year ended November 30, 2020, we had borrowings of $525 million and repayments of $526 million of commercial paper with original maturities greater than three months.

Summary of Significant Accounting Policies (Policies)	Nov. 30, 2022
Accounting Policies [Abstract]
Basis of Presentation	Basis of PresentationWe consolidate entities over which we have control, as typically evidenced by a voting control of greater than 50% or for which we are the primary beneficiary, whereby we have the power to direct the most significant activities and the obligation to absorb significant losses or receive significant benefits from the entity. We do not separately present our noncontrolling interests in the consolidated financial statements since the amounts are immaterial. For affiliates we do not control but where significant influence over financial and operating policies exists, as typically evidenced by a voting control of 20% to 50%, the investment is accounted for using the equity method.
Preparation of Financial Statements	Preparation of Financial Statements The preparation of our consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the amounts reported and disclosed in our consolidated financial statements. The full extent to which the effects of the pandemic, inflation, higher fuel prices, higher interest rates and fluctuations in foreign currency rates will directly or indirectly impact our business, operations, results of operations and financial condition, including our valuation of goodwill and trademarks, impairment of ships and collectability of trade and notes receivables, will depend on future developments that are uncertain. We have made reasonable estimates and judgments of such items within our financial statements and there may be changes to those estimates in future periods. Actual results may differ from the estimates used in preparing our consolidated financial statements. All material intercompany balances and transactions are eliminated in consolidation.
Cash and Cash Equivalents	Cash and Cash EquivalentsCash and cash equivalents include investments with maturities of three months or less at acquisition which are stated at cost and present insignificant risk of changes in value.
Restricted Cash	Restricted CashRestricted cash is classified as short-term or long-term based on the expected timing of our ability to access or use the amounts. The long-term portion is included within other assets. Substantially all restricted cash as of November 30, 2022 relates to the net proceeds from the issuance of our 2028 Senior Priority Notes, which became unrestricted in December 2022.
Inventories	InventoriesInventories consist substantially of food, beverages, hotel supplies, fuel and retail merchandise, which are all carried at the lower of cost or net realizable value. Cost is determined using the weighted-average or first-in, first-out methods.
Property and Equipment	Property and Equipment Property and equipment are stated at cost less accumulated depreciation and any impairment charges. We capitalize interest as part of the cost of capital projects incurred during construction. Depreciation is computed using the straight-line method over our estimated useful lives of the assets to a residual value, as a percentage of original cost, as follows: Years Residual Ships 30 15% Ship improvements 3-30 0% Buildings and improvements 10-40 0% Computer hardware and software 2-12 0% Transportation equipment and other 3-20 0% Leasehold improvements, including port facilities Shorter of the remaining lease term or related asset life (3-30) 0% The cost of ships under construction includes progress payments for the construction of new ships, as well as design and engineering fees, capitalized interest, construction oversight costs and various owner supplied items. Any liquidated damages received from shipyards are recorded as reductions to the cost basis of the ship. We have a capital program for the improvement of our ships and for asset replacements to enhance the effectiveness and efficiency of our operations; to comply with, or exceed, all relevant legal and statutory requirements related to health, environment, safety, security and sustainability; and to gain strategic benefits or provide improved product innovations to our guests. We account for ship improvement costs, including replacements of certain significant components and parts, by capitalizing those costs we believe add value to our ships and have a useful life greater than one year and depreciating those improvements over their estimated remaining useful life. The costs of repairs and maintenance, including those incurred when a ship is taken out-of-service for scheduled maintenance, and minor improvement costs and expenses, are charged to expense as incurred. In addition, specifically identified or estimated cost and accumulated depreciation of previously capitalized ship components are written-off upon retirement, which may result in a loss on disposal that is also included in other operating expenses. We have estimated our ships’ useful lives at 30 years and residual values at 15% of our original ship cost. Our ship useful life and residual value estimates take into consideration the estimated weighted-average useful lives of the ships' major component systems, such as hull, superstructure, main electric, engines and cabins. We also take into consideration the impact of technological changes, historical useful lives of similarly-built ships, long-term cruise and vacation market conditions and regulatory changes, including those related to the environment and climate change. We determine the residual value of our ships based on our long-term estimates of their resale value at the end of their useful life to us but before the end of their physical and economic lives to others, historical resale values of our and other cruise ships as well as our expectations of the long-term viability of the secondary cruise ship market. We review estimated useful lives and residual values for reasonableness whenever events or circumstances significantly change.
Leases	Leases Substantially all of our leases for which we are the lessee are operating leases of port facilities and real estate and are included within operating lease right-of-use assets, long-term operating lease liabilities and current portion of operating lease liabilities in our Consolidated Balance Sheets. We have port facilities and real estate lease agreements with lease and non-lease components, and in such cases, we account for the components as a single lease component. We do not recognize lease assets and lease liabilities for any leases with an original term of less than one year. For some of our port facilities and real estate lease agreements, we have the option to extend our current lease term by 1 to 10 years. Generally, we do not include renewal options as a component of our present value calculation as we are not reasonably certain that we will exercise the options. As most of our leases do not have a readily determinable implicit rate, we estimate the incremental borrowing rate (“IBR”) to determine the present value of lease payments. We apply judgment in estimating the IBR including considering the term of the lease, the currency in which the lease is denominated, and the impact of collateral and our credit risk on the rate. We amortize our lease assets on a straight-line basis over the lease term.
Goodwill and Other Intangibles	Goodwill and Other Intangibles Goodwill represents the excess of the purchase price over the fair value of identifiable net assets acquired in a business acquisition. We review our goodwill for impairment as of July 31 every year, or more frequently if events or circumstances dictate. All of our goodwill has been allocated to our reporting units. The impairment review for goodwill allows us to first assess qualitative factors to determine whether it is necessary to perform the more detailed quantitative goodwill impairment test. We would perform the quantitative test if our qualitative assessment determined it is more-likely-than-not that a reporting unit’s estimated fair value is less than its carrying amount. We may also elect to bypass the qualitative assessment and proceed directly to the quantitative test for any reporting unit. When performing the quantitative test, if the estimated fair value of the reporting unit exceeds its carrying value, no further analysis is required. However, if the estimated fair value of the reporting unit is less than the carrying value, goodwill is written down based on the difference between the reporting unit’s carrying amount and its fair value, limited to the amount of goodwill allocated to the reporting unit. Judgment is required in estimating the fair value of our reporting unit. Trademarks represent substantially all of our other intangibles. Trademarks are estimated to have an indefinite useful life and are not amortizable but are reviewed for impairment at least annually and as events or circumstances dictate. The impairment review for trademarks also allows us to first assess qualitative factors to determine whether it is necessary to perform a more detailed quantitative trademark impairment test. We would perform the quantitative test if our qualitative assessment determined it was more-likely-than-not that the trademarks are impaired. We may also elect to bypass the qualitative
Equity Method Investments	Equity Method Investments Equity method investments are initially recognized at cost and are included in other assets in the Consolidated Balance Sheets. Our proportionate interest in their results is included in other income (expense), net in the Consolidated Statements of Income.
Derivatives and Other Financial Instruments	Derivatives and Other Financial Instruments We have in the past and may in the future utilize derivative and non-derivative financial instruments, such as foreign currency forwards, options and swaps, foreign currency debt obligations and foreign currency cash balances, to manage our exposure to fluctuations in certain foreign currency exchange rates. We use interest rate swaps primarily to manage our interest rate exposure to achieve a desired proportion of fixed and floating rate debt. Our policy is to not use financial instruments for trading or other speculative purposes. All derivatives are recorded at fair value. If a derivative is designated as a cash flow hedge, then the change in the fair value of the derivative is recognized as a component of AOCI until the underlying hedged item is recognized in earnings or the forecasted transaction is no longer probable. If a derivative or a non-derivative financial instrument is designated as a hedge of our net investment in a foreign operation, then changes in the effective portion of the fair value of the financial instrument are recognized as a component of AOCI to offset the change in the translated value of the designated portion of net investment being hedged until the investment is sold or substantially liquidated, while the impact attributable to components excluded from the assessment of hedge effectiveness is recorded in interest expense, net of capitalized interest, on a systematic and rational basis. For derivatives that do not qualify for hedge accounting treatment, the change in fair value is recognized in earnings. We classify the fair value of all our derivative contracts as either current or long-term, depending on the maturity date of the derivative contract. The cash flows from derivatives treated as cash flow hedges are classified in our Consolidated Statements of Cash Flows in the same category as the item being hedged.
Foreign Currency Translation and Transactions	Foreign Currency Translation and Transactions These financial statements are presented in U.S. dollars. Each foreign entity determines its functional currency by reference to its primary economic environment. Our most significant foreign entities utilize the U.S. dollar, Euro, Sterling or the Australian dollar as their functional currencies. We translate the assets and liabilities of our foreign entities that have functional currencies other than the U.S. dollar at exchange rates in effect at the balance sheet date. Revenues and expenses of these foreign entities are translated at the average rate for the period. Equity is translated at historical rates and the resulting foreign currency translation adjustments are included as a component of AOCI, which is a separate component of shareholders’ equity. Therefore, the U.S. dollar value of the non-equity translated items in our consolidated financial statements will fluctuate from period to period, depending on the changing value of the U.S. dollar versus these currencies. We execute transactions in a number of different currencies. At the date that the transaction is recognized, each asset, liability, revenue, expense, gain or loss arising from the transaction is measured and recorded in the functional currency of the recording entity using the exchange rate in effect at that date. At each balance sheet date, recorded monetary balances denominated in a currency other than the functional currency are adjusted using the exchange rate at the balance sheet date, with gains or losses recorded in other income or other expense, unless such monetary balances have been designated as hedges of net investments in our foreign entities. The net gains or losses resulting from foreign currency transactions were not material in 2022, 2021 and
Revenue and Expense Recognition	Revenue and Expense Recognition Guest cruise deposits and advance onboard purchases are initially included in customer deposits when received. Customer deposits are subsequently recognized as cruise revenues, together with revenues from onboard and other activities, and all associated direct costs and expenses of a voyage are recognized as cruise costs and expenses, upon completion of voyages with durations of ten nights or less and on a pro rata basis for voyages in excess of ten nights. The impact of recognizing these shorter duration cruise revenues and costs and expenses on a completed voyage basis versus on a pro rata basis is not material. Certain of our product offerings are bundled and we allocate the value of the bundled services and goods between passenger ticket revenues and onboard and other revenues based upon the estimated standalone selling prices of those goods and services. Guest cancellation fees, when applicable, are recognized in passenger ticket revenues at the time of cancellation. Our sales to guests of air and other transportation to and from airports near the home ports of our ships are included in passenger ticket revenues, and the related costs of purchasing these services are included in transportation costs. The proceeds that we collect from the sales of third-party shore excursions are included in onboard and other revenues and the related costs are included in onboard and other costs. The amounts collected on behalf of our onboard concessionaires, net of the amounts remitted to them, are included in onboard and other revenues as concession revenues. All of these amounts are recognized on a completed voyage or pro rata basis as discussed above. Passenger ticket revenues include fees, taxes and charges collected by us from our guests. The fees, taxes and charges that vary with guest head counts and are directly imposed on a revenue-producing arrangement are expensed in commissions, transportation and other costs when the corresponding revenues are recognized. These fees, taxes and charges included in commissions, transportation and other costs were $438 million in 2022, $73 million in 2021 and $215 million in 2020. The remaining portion of fees, taxes and charges are expensed in other operating expenses when the corresponding revenues are recognized. Revenues and expenses from our hotel and transportation operations, which are included in our Tour and Other segment, are recognized at the time the services are performed. Customer Deposits Our payment terms generally require an initial deposit to confirm a reservation, with the balance due prior to the voyage. Cash received from guests in advance of the cruise is recorded in customer deposits and in other long-term liabilities on our Consolidated Balance Sheets. These amounts include refundable deposits. In certain situations, we have provided flexibility to guests by allowing guests to rebook at a future date, receive future cruise credits (“FCCs”) or elect to receive refunds in cash. We have at times issued enhanced FCCs. Enhanced FCCs provide the guest with an additional credit value above the original cash deposit received, and the enhanced value is recognized as a discount applied to the future cruise in the period used. We record a liability for unexpired FCCs to the extent we have received and not refunded cash from guests for cancelled bookings. We had total customer deposits of $5.1 billion and $3.5 billion as of November 30, 2022 and 2021, which includes approximately $210 million of unredeemed FCCs as of November 30, 2022. Given the uncertainty of travel demand caused by COVID-19 and lack of comparable historical experience of FCC redemptions, we are unable to estimate the number of FCCs that will not be used in future periods. Refunds payable to guests who have elected cash refunds are recorded in accounts payable. During 2022 and 2021, we recognized revenues of $1.9 billion and $0.1 billion related to our customer deposits as of November 30, 2021 and 2020. Historically, our customer deposits balance changes due to the seasonal nature of cash collections, the recognition of revenue, refunds of customer deposits and foreign currency changes. Contract Costs
Insurance	Insurance We use a combination of insurance and self-insurance to cover a number of risks including illness and injury to crew, guest injuries, pollution, other third-party claims in connection with our cruise activities, damage to hull and machinery for each of our ships, war risks, workers’ compensation, directors’ and officers’ liability, property damage and general liability for shoreside third-party claims. We recognize insurance recoverables from third-party insurers up to the amount of recorded losses at the time the recovery is probable and upon settlement for amounts in excess of the recorded losses. All of our insurance policies are subject to coverage limits, exclusions and deductible levels. The liabilities associated with crew illnesses and crew and guest injury claims, including all legal costs, are estimated based on the specific merits of the individual claims or actuarially estimated based on historical claims experience, loss development factors and other assumptions.
Selling and Administrative Expenses	Selling and Administrative ExpensesSelling expenses include a broad range of advertising, marketing and promotional expenses. Advertising is charged to expense as incurred, except for media production costs, which are expensed upon the first airing of the advertisement. Selling expenses totaled $744 million in 2022, $340 million in 2021 and $348 million in 2020. Administrative expenses represent the costs of our shoreside support, reservations and other administrative functions, and include salaries and related benefits, professional fees and building occupancy costs, which are typically expensed as incurred.
Share-Based Compensation	Share-Based CompensationWe recognize compensation expense for all share-based compensation awards using the fair value method. For time-based share awards, we recognize compensation cost ratably using the straight-line attribution method over the expected vesting period or to the retirement eligibility date, if earlier than the vesting period. For performance-based share awards, we estimate compensation cost based on the probability of the performance condition being achieved and recognize expense ratably using the straight-line attribution method over the expected vesting period. If all or a portion of the performance condition is not expected to be met, the appropriate amount of previously recognized compensation expense is reversed and future compensation expense is adjusted accordingly. For market-based share awards, we recognize compensation cost ratably using the straight-line attribution method over the expected vesting period. If the target market conditions are not expected to be met, compensation expense will still be recognized. We account for forfeitures as they occur.
Earnings Per Share	Earnings Per ShareBasic earnings per share is computed by dividing net income (loss) by the weighted-average number of shares outstanding during each period. Diluted earnings per share is computed by dividing net income (loss) by the weighted-average number of shares and common stock equivalents outstanding during each period. For earnings per share purposes, Carnival Corporation common stock and Carnival plc ordinary shares are considered a single class of shares since they have equivalent rights.
Accounting Pronouncements	Accounting Pronouncements In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU No. 2020-04”), which provides temporary optional expedients and exceptions to accounting guidance on contract modifications and hedge accounting to ease entities’ financial reporting burdens as the market transitions from the London Interbank Offered Rate (“LIBOR”) and other interbank offered rates to alternative reference rates. ASU 2020-04 is effective upon issuance. In December 2022, the FASB deferred the date for which this guidance can be applied from December 31, 2022 to December 31, 2024. The use of LIBOR was phased out at the end of 2021, although the phase-out of U.S. dollar LIBOR for existing agreements has been delayed until June 2023. We continue to monitor developments related to the LIBOR transition and identification of an alternative, market-accepted rate. In December 2021, we amended our £350 million long-term debt agreement which referenced the British Pound sterling (“GBP”) LIBOR to the Sterling Overnight Index Average (“SONIA”) and applied the practical expedient. This amendment did not have a material impact on our consolidated financial statements. As of November 30, 2022, approximately $5.8 billion of our outstanding indebtedness bears interest at floating rates referenced to U.S. dollar LIBOR with maturity dates extending beyond June 30, 2023. We are currently evaluating our contracts referenced to U.S. dollar LIBOR and working with our creditors on updating credit agreements as necessary to include language regarding the successor or alternate rate to LIBOR. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements during the LIBOR transition period. The FASB issued guidance, Debt - Debt with Conversion and Other Options and Derivative and Hedging - Contracts in Entity’s Own Equity, which simplifies the accounting for convertible instruments. This guidance eliminates certain models that require separate accounting for embedded conversion features, in certain cases. Additionally, among other changes, the guidance eliminates certain of the conditions for equity classification for contracts in an entity’s own equity. The guidance also requires entities to use the if-converted method for all convertible instruments in the diluted earnings per share calculation and include the effect of share settlement for instruments that may be settled in cash or shares, except for certain liability-classified share-based payment awards. We will adopt this guidance in the first quarter of 2023 using the modified retrospective approach. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In September 2022, the FASB issued ASU No. 2022-04, Liabilities-Supplier Finance Programs (Subtopic 405-50) - Disclosure of Supplier Finance Program Obligations. This ASU requires that a buyer in a supplier finance program disclose sufficient information about the program to allow a user of financial statements to understand the program’s nature, activity during the period, changes from period to period, and potential magnitude. This ASU is expected to improve financial reporting by requiring new disclosures about the programs, thereby allowing financial statement users to better consider the effect of the programs on an entity’s working capital, liquidity, and cash flows. This ASU is effective for fiscal years beginning after December 15, 2022, except for the amendment on roll forward information which is effective for fiscal years beginning after December 15, 2023. We are currently evaluating the impact of the new guidance on the disclosures to our consolidated financial statements.
