At November 30, 2014 and 2013, the net carrying values of ships and ships under construction for our North America, EAA, Cruise Support and Tour and Other segments were $18.6 billion, $12.6 billion, $0.3 billion and $0.1 billion and $18.3 billion, $13.2 billion, $0.3 billion and $0.1 billion, respectively.

[2]

The debt table does not include the impact of our foreign currency and interest rate swaps. At November 30, 2014, 67% and 33% (69% and 31% at November 30, 2013) of our debt was U.S. dollar and euro-denominated, respectively, including the effect of foreign currency swaps. At November 30, 2014, 52% and 48% (59% and 41% at November 30, 2013) of our debt bore fixed and floating interest rates, respectively, including the effect of interest rate swaps. Substantially all of our fixed rate debt can only be called or prepaid by incurring additional costs. In addition, substantially all of our debt agreements, including our main revolving credit facility, contain one or more financial covenants that require us, among other things, to maintain minimum debt service coverage and minimum shareholders’ equity and to limit our debt to capital and debt to equity ratios and the amounts of our secured assets and secured and other indebtedness. Generally, if an event of default under any debt agreement occurs, then pursuant to cross default acceleration clauses, substantially all of our outstanding debt and derivative contract payables (see Note 10) could become due, and all debt and derivative contracts could be terminated. At November 30, 2014, we believe we were in compliance with all of our debt covenants.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

General

Description of Business

Carnival Corporation is incorporated in Panama and Carnival plc is incorporated in England and Wales. Carnival Corporation and Carnival plc operate a dual listed company (“DLC”), whereby the businesses of Carnival Corporation and Carnival plc are combined through a number of contracts and through provisions in Carnival Corporation’s Articles of Incorporation and By-Laws and Carnival plc’s Articles of Association. The two companies operate as if they are a single economic enterprise, 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. In addition, Carnival plc American Depository Shares are traded on the NYSE (see Note 3).

The consolidated financial statements include the accounts of Carnival Corporation and Carnival plc and their respective subsidiaries. Together with their consolidated subsidiaries, they are referred to collectively in these consolidated financial statements and elsewhere in this 2014 Annual Report as “Carnival Corporation & plc,” “our,” “us” and “we.”

We are the largest cruise company and among the largest leisure travel companies in the world. Each of our nine leading global, regional and national brands is an operating segment that we aggregate into either the (1) North America or (2) Europe, Australia & Asia (“EAA”) reportable cruise segments (see Note 11). As of January 22, 2015, our cruise brands’ summary information is as follows:



Cruise Brands	Passenger Capacity (a)	Percentage of Total Capacity		Number of Cruise Ships
North America
Carnival Cruise Line	62,366	29	%	24
Princess Cruises (“Princess”)	44,090	21		18
Holland America Line	23,540	11		15
Seabourn	1,782	1		5
North America Cruise Brands	131,778	62		62
EAA
Costa Cruises (“Costa”)	35,828	17		15
AIDA Cruises (“AIDA”)	18,656	9		10
P&O Cruises (UK)	14,736	7		7
Cunard	6,694	3		3
P&O Cruises (Australia)	4,804	2		3
EAA Cruise Brands	80,718	38		38
	212,496	100	%	100


(a)	In accordance with cruise industry practice, passenger capacity is calculated based on the assumption of two passengers per cabin even though some cabins can accommodate three or more passengers.

Accounting Policies [Abstract]

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 (see Note 3). We do not separately present our noncontrolling interests in the consolidated financial statements since the amounts are insignificant. 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

The preparation of our consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported and disclosed in our financial statements. Actual results may differ from the estimates used in preparing our consolidated financial statements. All significant intercompany balances and transactions are eliminated in consolidation. Certain prior period amounts have been reclassified in the Consolidated Balance Sheets and the Consolidated Statements of Cash Flows to conform to the current period presentation. The reclassifications in the Consolidated Statements of Cash Flows had no impact on net cash provided by operating activities and net cash used in investing and financing activities.

Cash and Cash Equivalents

Cash and cash equivalents include investments with maturities of three months or less at acquisition, which are stated at cost. At November 30, 2014 and 2013, cash and cash equivalents are comprised of cash on hand, money market funds and time deposits.

Inventories

Inventories consist substantially of food and beverages, hotel and restaurant products and supplies, fuel and gift shop merchandise held for resale, which are all carried at the lower of cost or market. Cost is determined using the weighted-average or first-in, first-out methods.

Property and Equipment

Property and equipment are stated at cost. Depreciation and amortization were computed using the straight-line method over our estimates of useful lives and residual values, as a percentage of original cost, as follows:



	Years	Residual Values
Ships	30	15%
Ship improvements	Shorter of remaining ship life or useful life (3-28)	0%
Buildings and improvements	10-35	0% or 10%
Computer hardware and software	3-10	0% or 10%
Transportation equipment and other	3-20	0% or 10%
Leasehold improvements, including port facilities	Shorter of lease term or related asset life (3-30)	—

The cruise industry is very capital intensive, and at January 22, 2015, we operated 100 cruise ships. Therefore, we have a capital program that we develop for the improvement of our ships and for asset replacements in order to enhance the effectiveness and efficiency of our operations; comply with, or exceed all relevant legal and statutory requirements related to health, environment, safety, security and sustainability; and gain strategic benefits or provide newer improved product innovations to our guests.

Ship improvement costs that we believe add value to our ships, such as those discussed above, are capitalized to the ships and depreciated over the shorter of their or the ships’ estimated remaining useful life, while costs of repairs and maintenance, including minor improvement costs and dry-dock expenses, are charged to expense as incurred and included in other ship operating expenses. Dry-dock costs primarily represent planned major maintenance activities that are incurred when a ship is taken out-of-service for scheduled maintenance. We capitalize interest as part of the cost of acquiring ships and other capital projects during their construction period. The 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 ship operating expenses.

We review our long-lived assets, principally our ships, for impairment whenever events or changes in circumstances indicate that the carrying amounts of these assets may not be fully recoverable. Upon the occurrence of a triggering event, the assessment of possible impairment is based on our ability to recover the carrying value of our asset, which is determined by using the asset’s estimated undiscounted future cash flows. If these estimated undiscounted future cash flows are less than the carrying value of the asset, an impairment charge is recognized for the excess, if any, of the asset’s carrying value over its estimated fair value. As it relates to our ships, the lowest level for which we maintain identifiable cash flows that are independent of the cash flows of other assets and liabilities is at the individual ship level.

A significant amount of judgment is required in estimating the future cash flows and fair values of our cruise ships.

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 at least annually and, when events or circumstances dictate, more frequently. All of our goodwill has been allocated to our reporting units, also referred to as “cruise brands.” The impairment review for goodwill allows us to first assess qualitative factors to determine whether it is necessary to perform the more detailed two-step quantitative goodwill impairment test. We would perform the quantitative test if our qualitative assessment determined it is more-likely-than-not that a cruise brand’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 cruise brand. When performing the quantitative test, if the estimated fair value of the cruise brand exceeds its carrying value, no further analysis or write-down of goodwill is required. However, if the estimated fair value of the cruise brand is less than the carrying value of its net assets, the estimated fair value of the cruise brand is assigned to all its underlying assets and liabilities, including both recognized and unrecognized tangible and intangible assets, based on their fair values. If necessary, goodwill is then written down to its implied fair value.

Trademarks represent substantially all of our other intangibles. For certain acquisitions, we have allocated a portion of the purchase prices to the acquiree’s identified trademarks. Trademarks are estimated to have an indefinite useful life and, therefore, are not amortizable, but are reviewed for impairment at least annually and, when events or circumstances dictate, more frequently. 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. The costs of developing and maintaining our trademarks are expensed as incurred.

A significant amount of judgment is also required in estimating the fair values of our cruise brands and trademarks.

Revenue and Expense Recognition

Guest cruise deposits represent unearned revenues and are initially included in customer deposit liabilities 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 significant. Future travel discount vouchers issued to guests are included as a reduction of cruise passenger ticket revenues when such vouchers are utilized. Guest cancellation fees are recognized in cruise passenger ticket revenues at the time of the cancellation.

Our sale to guests of air and other transportation to and from airports near the home ports of our ships and the related cost of purchasing these services are included in cruise passenger ticket revenues and cruise transportation costs, respectively. The proceeds that we collect from the sales of third-party shore excursions and on behalf of our onboard concessionaires, net of the amounts remitted to them, are included in onboard and other cruise revenues as concession revenues. All of these amounts are recognized on a completed voyage or pro rata basis as discussed above.

Cruise passenger ticket revenues include fees, taxes and charges collected by us from our guests. A portion of these fees, taxes and charges vary with guest head counts and are directly imposed on a revenue-producing arrangement. This portion of the fees, taxes and charges is expensed in commissions, transportation and other costs when the corresponding revenues are recognized. These fees, taxes and charges included in passenger ticket revenues and commissions, transportation and other costs were $532 million, $517 million and $477 million in 2014, 2013 and 2012, respectively. The remaining portion of fees, taxes and charges are also included in cruise passenger ticket revenues but are expensed in other ship 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 or expenses are incurred. Revenues from the long-term leasing of ships, which are also included in our Tour and Other segment, are recognized ratably over the term of the charter agreement using the straight-line method (see Note 11).

Insurance

We maintain 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, damages to hull and machinery for each of our ships, war risks, workers’ compensation, employee health, directors and officers liability, property damages and general liabilities for third-party claims. We recognize insurance recoverables from third-party insurers for incurred expenses at the time the recovery is probable and upon realization for amounts in excess of incurred expenses. 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. While we believe our estimated accrued claims reserves are adequate, the ultimate losses will differ.

At November 30, 2014 and 2013, substantially all of our aggregated short-term and long-term insurance recoverables are for crew, guest and other third-party claims related to the January 2012 ship incident. At November 30, 2014 and 2013, the majority of our aggregated short-term and long-term claims reserves also relate to this January 2012 ship incident. At November 30, 2014 and 2013, our long-term insurance recoverables and long-term claims reserve are included in other assets and other long-term liabilities, respectively, and are not material.

Selling and Administrative Expenses

Selling expenses include a broad range of advertising, such as marketing and promotional expenses. Advertising is charged to expense as incurred, except for media production costs. Brochures and media production costs are recorded as prepaid expenses and charged to expense as consumed or upon the first airing of the advertisement, respectively. Advertising expenses totaled $623 million, $588 million and $527 million in 2014, 2013 and 2012, respectively. Administrative expenses represent the costs of our shoreside ship support, reservations and other administrative functions, and includes salaries and related benefits, professional fees and occupancy costs, which are typically expensed as incurred.

Foreign Currency Translations and Transactions

Each business determines its functional currency by reference to its primary economic environment. We translate the assets and liabilities of our foreign operations 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 operations are translated at weighted-average exchange rates for the period. Their equity is translated at historical rates and the resulting foreign currency translation adjustments are included as a component of accumulated other comprehensive income (“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, principally the U.S. dollar, euro, sterling and Australian dollar. Exchange rate gains and losses arising from changes in foreign currency exchange rates between the time an expense is recorded and when it is settled as well as the remeasurement of monetary assets and liabilities, all denominated in a currency other than the functional currency of the entity involved, are recognized currently in nonoperating earnings, unless such monetary liabilities have been designated to act as hedges of net investments in our foreign operations. The net gains or losses resulting from these "nonoperating foreign currency transactions" were insignificant in 2014, 2013 and 2012. In addition, the unrealized gains or losses on our long-term intercompany receivables denominated in a non-functional currency, which are not expected to be repaid in the foreseeable future and are therefore considered to form part of our net investments, are recorded as foreign currency translation adjustments, which are included as a component of AOCI.

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 less than the vesting period, when vesting is not contingent upon any future performance. For performance-based share awards, we generally recognize compensation cost ratably using the straight-line attribution method over the expected vesting period based on the probability of the performance condition being achieved. If all or a portion of the performance condition is not expected to be met, the appropriate amount of previously recognized compensation expense will be reversed and future compensation expense will be 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. In addition, we estimate the amount of expected forfeitures based on historical forfeiture experience when calculating compensation cost. If the actual forfeitures that occur are significantly different from the estimate, then we revise our estimates.

Earnings Per Share

Basic earnings per share is computed by dividing net income by the weighted-average number of shares outstanding during each period. Diluted earnings per share is computed by dividing net income 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 (see Note 3).

DLC Arrangement	12 Months Ended
DLC Arrangement	Nov. 30, 2014
Dual Listed Company Arrangement [Abstract]
DLC Arrangement	DLC Arrangement In 2003, Carnival Corporation and Carnival plc completed a DLC transaction, which implemented Carnival Corporation and Carnival plc’s DLC arrangement. The contracts governing the DLC arrangement provide that Carnival Corporation and Carnival plc each continue to have separate boards of directors, but the boards and senior executive management of both companies are identical. The constitutional documents of each of the companies also provide that, on most matters, the holders of the common equity of both companies effectively vote as a single body. On specified matters where the interests of Carnival Corporation’s shareholders may differ from the interests of Carnival plc’s shareholders (a “class rights action” such as transactions primarily designed to amend or unwind the DLC arrangement), each shareholder body will vote separately as a class. Generally, no class rights action will be implemented unless approved by both shareholder bodies. Upon the closing of the DLC transaction, Carnival Corporation and Carnival plc also executed the Equalization and Governance Agreement, which 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 Carnival plc ordinary share is entitled to the same distributions, subject to the terms of the Equalization and Governance Agreement, as one share of Carnival Corporation common stock. In a liquidation of either company or both companies, if the hypothetical potential per share liquidation distributions to each company’s shareholders are not equivalent, taking into account the relative value of the two companies’ assets and the indebtedness of each company, to the extent that one company has greater net assets so that any liquidation distribution to its shareholders would not be equivalent on a per share basis, the company with the ability to make a higher net distribution is required to make a payment to the other company to equalize the possible net distribution to shareholders, subject to certain exceptions. At the closing of the DLC transaction, Carnival Corporation and Carnival plc also executed deeds of guarantee. Under the terms of Carnival Corporation’s deed of guarantee, Carnival Corporation has agreed to guarantee all indebtedness and certain other monetary obligations of Carnival plc that are incurred under agreements entered into on or after the closing date of the DLC transaction. The terms of Carnival plc’s deed of guarantee mirror those of Carnival Corporation’s. In addition, Carnival Corporation and Carnival plc have each extended their respective deeds of guarantee to the other’s pre-DLC indebtedness and certain other monetary obligations, or alternatively have provided standalone guarantees in lieu of utilization of these deeds of guarantee, thus effectively cross guaranteeing all Carnival Corporation and Carnival plc indebtedness and certain other monetary obligations. Each deed of guarantee provides that the creditors to whom the obligations are owed are intended third-party beneficiaries of such deed of guarantee. The deeds of guarantee are governed and construed in accordance with the laws of the Isle of Man. Subject to the terms of the deeds of guarantee, the holders of indebtedness and other obligations that are subject to the deeds of guarantee will have recourse to both Carnival plc and Carnival Corporation, though a Carnival plc creditor must first make written demand on Carnival plc and a Carnival Corporation creditor on Carnival Corporation. Once the written demand is made by letter or other form of notice, the holders of indebtedness or other obligations may immediately commence an action against the relevant guarantor. Accordingly, there is no requirement under the deeds of guarantee to obtain a judgment, take other enforcement actions or wait any period of time prior to taking steps against the relevant guarantor. All actions or proceedings arising out of or in connection with the deeds of guarantee must be exclusively brought in courts in England. Under the terms of the DLC transaction documents, 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. The companies have entered into some of these types of transactions and may enter into additional transactions in the future to take advantage of the flexibility provided by the DLC arrangement, and to operate both companies as a single unified economic enterprise in the most effective manner. In addition, under the terms of the Equalization and Governance Agreement and the deeds of guarantee, 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 both Carnival Corporation and Carnival plc have not been presented.

(a)	At November 30, 2014 and 2013, the net carrying values of ships and ships under construction for our North America, EAA, Cruise Support and Tour and Other segments were $18.6 billion, $12.6 billion, $0.3 billion and $0.1 billion and $18.3 billion, $13.2 billion, $0.3 billion and $0.1 billion, respectively.

Ships under construction include 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. Capitalized interest, substantially all included in our ships under construction, amounted to $21 million, $15 million and $17 million in 2014, 2013 and 2012, respectively.

Repairs and maintenance expenses, including minor improvement costs and dry-dock expenses, were $918 million, $954 million and $832 million in 2014, 2013 and 2012, respectively, and are substantially all included in other ship operating expenses.

During 2012, we wrote-off the net carrying value of a ship related to the January 2012 ship incident and received €395 million (or $508 million) of hull and machinery insurance proceeds for the total loss of the ship. As a result, in 2012 we recognized €14 million (or $17 million) of proceeds in excess of the net carrying value of the ship as a reduction of other ship operating expenses. In addition, during 2012 we incurred $28 million of January 2012 ship incident-related expenses, that were not covered by insurance and are principally included in other ship operating expenses. See Note 7 for a discussion of loss contingencies related to the January 2012 ship incident.

(b)	Includes $2.4 billion of debt whose interest rates, and in the case of our main revolver its commitment fees, would increase upon a downgrade in the long-term senior unsecured credit ratings of Carnival Corporation or Carnival plc.


(c)	In 2014, we repaid an aggregate of $590 million outstanding under two export credit facilities prior to their maturities through May 2024. In addition, in 2014 we borrowed $554 million under an export credit facility, the proceeds of which were used to pay for a portion of Regal Princess’ purchase price and is due in semi-annual installments through May 2026.


(d)	In 2014, we borrowed $498 million under a euro-denominated export credit facility, the proceeds of which were used to pay for a portion of Costa Diadema's purchase price and is due in semi-annual installments through October 2026.

(e)

In 2014, we restructured two floating rate bank loan facilities that had an aggregate outstanding balance of $250 million and were previously due through 2016. The restructuring converted the terms into perpetual one-year maturities and added a $150 million tranche, which was used to repay a portion of a $500 million fixed rate bank loan in 2014 prior to its 2015 maturity date. We can terminate this facility at any time upon three days notice, and the bank can terminate the facility at any time upon one-year’s notice.


(f)	In 2014, we borrowed $150 million under a floating rate bank loan, which is due in September 2019. We used the net proceeds of this loan for general corporate purposes.


(g)	In 2014, we borrowed $275 million under a euro-denominated floating rate revolving bank loan facility, the proceeds of which were used for general corporate purposes. This facility has a perpetual term although we can terminate it at any time, and the bank can terminate the facility at any time upon nine months notice.


(h)	The interest rate associated with our short-term borrowings represents an aggregate-weighted average interest rate.

At November 30, 2014, the scheduled annual maturities of our debt were as follows (in millions):

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. In addition, all debt issue discounts are amortized to interest expense using the effective interest rate method over the term of the notes.

Committed Ship Financings

We have unsecured euro and U.S. dollar long-term export credit committed ship financings in order to pay for a portion of our ships’ purchase prices. These commitments, if drawn, are repayable semi-annually over 12 years. We have the option to cancel each one at specified dates prior to the underlying ship’s delivery date.

Revolving Credit Facilities

In June 2014, Carnival Corporation, Carnival plc and certain of Carnival plc’s subsidiaries amended and replaced their existing five-year multi-currency revolving credit facility of $2.5 billion (comprised of $1.6 billion, €450 million and £150 million) with a new five-year multi-currency revolving credit facility (the “Facility”). This Facility of $2.6 billion (comprised of $1.7 billion, €500 million and £150 million) at November 30, 2014 expires in June 2019, and we have options to extend this Facility through June 2021 subject to the approval of each bank. The Facility currently bears interest at LIBOR/EURIBOR plus a margin of 40 basis points (“bps”). The margin varies based on changes to Carnival Corporation’s and Carnival plc’s long-term senior unsecured credit ratings. We are required to pay a commitment fee of 35% of the margin per annum on any undrawn portion. We will also incur an additional utilization fee of 10 bps, 20 bps or 40 bps if equal to or less than one-third, more than one-third or more than two-thirds of the Facility, respectively, is drawn on the total amount outstanding.

At November 30, 2014, we have two other undrawn revolving credit facilities for $300 million and $75 million that expire in 2020 and 2015, respectively, and provide us with additional liquidity. At November 30, 2014, $2.9 billion was available under all of our revolving credit facilities.

Ship Commitments

At November 30, 2014, as adjusted for our new ship orders through January 22, 2015, we had ten ships under contract for construction with an aggregate passenger capacity of more than 28,200 lower berths. The estimated total cost of these ships is $6.2 billion, which includes the contract prices with the shipyards, design and engineering fees, capitalized interest, construction oversight costs and various owner supplied items. We have paid $0.5 billion through November 30, 2014 and anticipate paying $1.6 billion, $1.9 billion, $0.8 billion and $1.4 billion of the remaining estimated total costs in 2015, 2016, 2017 and 2018, respectively.

Operating Leases, Port Facilities and Other Commitments

Rent expense under our operating leases, principally for office and warehouse space, was $63 million, $61 million and $57 million in 2014, 2013 and 2012, respectively.

At November 30, 2014, minimum amounts payable for our operating leases, with initial or remaining terms in excess of one year, and for the annual usage of port facilities and other contractual commitments with remaining terms in excess of one year, were as follows (in millions):

Contingencies	12 Months Ended
Contingencies	Nov. 30, 2014
Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Litigation As a result of the January 2012 ship incident, litigation claims, enforcement actions, regulatory actions and investigations, including, but not limited to, those arising from personal injury, loss of life, loss of or damage to personal property, business interruption losses or environmental damage to any affected coastal waters and the surrounding areas, have been and may be asserted or brought against various parties, including us. The existing assertions are ongoing and there are significant jurisdictional uncertainties. The ultimate outcome of these matters cannot be determined at this time. However, we do not expect these matters to have a significant impact on our results of operations because we have insurance coverage for these types of third-party claims. The UK Maritime & Coastguard Agency and the U.S. Department of Justice are investigating allegations that Caribbean Princess breached international pollution laws. We are cooperating with the investigations, including conducting our own internal investigation into the matter. The ultimate outcome of this matter cannot be determined at this time. However, we do not expect it to have a significant impact on our results of operations. Additionally, in the normal course of our business, various claims and lawsuits have been filed or are pending against us. Most of these claims and lawsuits are covered by insurance and, accordingly, the maximum amount of our liability, net of any insurance recoverables, is typically limited to our self-insurance retention levels. Management believes the ultimate outcome of these claims and lawsuits will not have a material adverse impact on our consolidated financial statements. Contingent Obligations – Lease Out and Lease Back Type (“LILO”) Transactions At November 30, 2014, Carnival Corporation had estimated contingent obligations totaling $397 million, excluding termination payments as discussed below, to participants in LILO transactions for two of its ships. At the inception of these leases, the aggregate of the net present value of these obligations was paid by Carnival Corporation to a group of major financial institutions, who agreed to act as payment undertakers and directly pay these obligations. As a result, these contingent obligations are considered extinguished and neither the funds nor the contingent obligations have been included in our Consolidated Balance Sheets. In the event that Carnival Corporation were to default on its contingent obligations and assuming performance by all other participants, we estimate that it would, as of November 30, 2014, be responsible for a termination payment of $31 million. In 2017, Carnival Corporation has the right to exercise options that would terminate these LILO transactions at no cost to it. If the credit rating of one of the financial institutions who is directly paying the contingent obligations falls below AA-, or below A- for the other financial institution, then Carnival Corporation will be required to replace the applicable financial institution with another financial institution whose credit rating is at least AA or meets other specified credit requirements. In such circumstances, it would incur additional costs, although we estimate that they would not be material to our consolidated financial statements. The financial institution payment undertaker subject to the AA- credit rating threshold has a credit rating of AA, and the financial institution subject to the A- credit rating threshold has a credit rating of A+. If Carnival Corporation's credit rating, which is BBB+, falls below BBB, it will be required to provide a standby letter of credit for $36 million, or, alternatively, provide mortgages for this aggregate amount on these two ships. Contingent Obligations – Indemnifications Some of the debt contracts that we enter into include indemnification provisions that obligate us to make payments to the counterparty if certain events occur. These contingencies generally relate to changes in taxes and changes in laws that increase lender capital costs and other similar costs. The indemnification clauses are often standard contractual terms and were entered into in the normal course of business. 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. We have not been required to make any material payments under such indemnification clauses in the past and, under current circumstances, we do not believe a request for material future indemnification payments is probable.

- Definition

The entire disclosure for loss and gain contingencies. Describes any existing condition, situation, or set of circumstances involving uncertainty as of the balance sheet date (or prior to issuance of the financial statements) as to a probable or reasonably possible loss incurred by an entity that will ultimately be resolved when one or more future events occur or fail to occur, and typically discloses the amount of loss recorded or a range of possible loss, or an assertion that no reasonable estimate can be made.

Taxation	12 Months Ended
Taxation	Nov. 30, 2014
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. 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. (an “equivalent exemption jurisdiction”) and (ii) the foreign corporation meets a defined 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 Carnival Corporation currently qualifies as a publicly-traded corporation 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 items that the Internal Revenue Service (“IRS”) does not consider to be incidental to ship operations. Among the items 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 Italian resident subsidiary currently qualifies for exemption from U.S. federal income tax under applicable bilateral U.S. income tax treaties. 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. Carnival Corporation and Carnival plc and certain of their 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 the UK tonnage tax on a rolling 10-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. Dividends received from subsidiaries of Carnival plc doing business outside the UK are generally exempt from 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 market are exempt from Australian corporation tax by virtue of the UK/Australian income tax treaty. Italian and German Income Tax In early 2015, Costa and AIDA will reelect to enter the Italian tonnage tax regime through 2024 and can reapply for an additional ten-year period beginning in early 2025. Companies to which the tonnage tax regime applies pay corporation taxes on shipping profits calculated by reference to the net tonnage of qualifying ships. Most of Costa’s and AIDA’s earnings not considered to be shipping profits for Italian tonnage tax purposes will be taxed at an effective tax rate of 5.5% under the Italian International shipping tax regime since all of their ships are Italian registered. Substantially all of AIDA’s earnings are exempt from Italian and German corporation tax by virtue of the Italy/Germany income tax treaty. Income and Other Taxes in Asian Countries Substantially all of our brands’ income from their international operation in Asian countries is exempt from local corporation tax by virtue of relevant income tax treaties. Other We recognize income tax benefits 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. All interest expense related to income tax liabilities is included in income tax expense. 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 significant to our financial position. We do not expect to incur income taxes on future distributions of undistributed earnings of foreign subsidiaries and, accordingly, no deferred income taxes have been provided for the distribution of these earnings. In addition to or in place of income taxes, virtually all jurisdictions where our ships call impose taxes, fees and other charges based on guest counts, ship tonnage, passenger capacity or some other measure, and these taxes, fees and other charges are included in commissions, transportation and other costs and other ship operating expenses.

Equity [Abstract]

Shareholders' Equity

Shareholders’ Equity

Carnival Corporation’s Articles of Incorporation authorize its Board of Directors, at its discretion, to issue up to 40 million shares of preferred stock. At November 30, 2014 and 2013, no Carnival Corporation preferred stock had been issued and only a nominal amount of Carnival plc preference shares had been issued. Our Boards of Directors have authorized, subject to certain restrictions, the repurchase of up to an aggregate of $1 billion of Carnival Corporation common stock and/or Carnival plc ordinary shares (the “Repurchase Program”). The Repurchase Program does not have an expiration date and may be discontinued by our Boards of Directors at any time.

During 2014, there were no repurchases of Carnival Corporation common stock under the Repurchase Program. In 2013 and 2012, we repurchased 2.8 million and 2.6 million shares of Carnival Corporation common stock for $103 million and $90 million, respectively, under the Repurchase Program. During 2014, 2013 and 2012, there were no repurchases of Carnival plc ordinary shares under the Repurchase Program. Since March 2013, the remaining availability under the Repurchase Program has been $975 million.

In addition to the Repurchase Program, the Boards of Directors authorized, in October 2008, the repurchase of up to 19.2 million Carnival plc ordinary shares and, in January 2013, the repurchase of up to 32.8 million shares of Carnival Corporation common stock under the Stock Swap programs described below. Depending on market conditions and other factors, we may repurchase shares of Carnival Corporation common stock and/or Carnival plc ordinary shares under the Repurchase Program and the Stock Swap programs concurrently. We use the Stock Swap programs in situations where we can obtain an economic benefit because either Carnival Corporation common stock or Carnival plc ordinary shares are trading at a price that is at a premium or discount to the price of Carnival plc ordinary shares or Carnival Corporation common stock, as the case may be. Any realized economic benefit under the Stock Swap programs is used for general corporate purposes, which could include repurchasing additional stock under the Repurchase Program. Carnival plc ordinary share repurchases under both the Repurchase Program and the Stock Swap programs require annual shareholder approval. The existing shareholder approval is limited to a maximum of 21.5 million ordinary shares and is valid until the earlier of the conclusion of the Carnival plc 2015 annual general meeting or October 16, 2015. At January 22, 2015, the remaining availability under the Stock Swap programs was 18.1 million Carnival plc ordinary shares and 32.0 million shares of Carnival Corporation common stock.

During 2014 and 2012, no Carnival Corporation common stock or Carnival plc ordinary shares were sold or repurchased under the Stock Swap programs. During 2013, Carnival Investments Limited, a wholly owned subsidiary of Carnival Corporation, sold 0.9 million of Carnival plc ordinary shares for net proceeds of $35 million. Substantially all of the net proceeds from these sales were used to repurchase 0.9 million shares of Carnival Corporation common stock. Pursuant to our Stock Swap programs, Carnival Corporation sold these Carnival plc ordinary shares owned by Carnival Investments Limited only to the extent it was able to repurchase shares of Carnival Corporation common stock in the U.S. market on at least an equivalent basis. During 2013, no Carnival Corporation common stock was sold or Carnival plc ordinary shares were repurchased under the Stock Swap programs.

At November 30, 2014, there were 15.9 million shares of Carnival Corporation common stock reserved for issuance under its employee benefit and dividend reinvestment plans. At November 30, 2014, there were 8.4 million ordinary shares of Carnival plc authorized for future issuance under its employee benefit plans.

On November 15, 2012, our Boards of Directors declared a special dividend to holders of Carnival Corporation common stock and Carnival plc ordinary shares of $0.50 per share, or $0.4 billion, which was paid in December 2012. The special dividend was in addition to our $0.25 per share regular 2012 quarterly dividend.

Accumulated other comprehensive (loss) income was as follows (in millions):



	November 30,
	2014			2013
Cumulative foreign currency translation adjustments, net	$	(512	)	$	234
Unrecognized pension expenses	(90		)	(97		)
Unrealized losses on marketable securities	(5		)	(7		)
Net (losses) gains on cash flow derivative hedges	(9		)	31
	$	(616	)	$	161

During 2014, $18 million of unrecognized pension expenses were reclassified out of accumulated other comprehensive (loss) income, of which $12 million and $6 million were included in payroll and related expenses and selling and administrative expenses, respectively.

Fair Value Measurements, Derivative Instruments and Hedging Activities

Fair Value Disclosures [Abstract]

Fair Value Measurements, Derivative Instruments and Hedging Activities

Fair Value Measurements

U.S. accounting standards establish a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:


•	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.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between independent and knowledgeable market participants at the measurement date. Therefore, even when market assumptions are not readily available, our own assumptions are set to reflect those that we believe market participants would use in pricing the asset or liability at the measurement date.

The fair value measurement of a financial asset or financial liability must reflect the nonperformance risk of the counterparty and us. Therefore, the impact of our counterparty’s creditworthiness was considered when in an asset position, and our creditworthiness was considered when in a liability position in the fair value measurement of our financial instruments. Creditworthiness did not have a significant impact on the fair values of our financial instruments at November 30, 2014 and 2013. Both the counterparties and we are expected to continue to perform under the contractual terms of the instruments. Considerable judgment may be required in interpreting market data used to develop the estimates of fair value. Accordingly, certain estimates of fair value presented herein are not necessarily indicative of the amounts that could be realized in a current or future market exchange.

Financial Instruments that are Not Measured at Fair Value on a Recurring Basis

The estimated carrying and fair values and basis of valuation of our financial instrument assets and liabilities that are not measured at fair value on a recurring basis were as follows (in millions):



	November 30, 2014								November 30, 2013
	Carrying Value		Fair Value						Carrying Value		Fair Value
	Carrying Value		Level 1		Level 2		Level 3		Carrying Value		Level 1		Level 2		Level 3
Assets
Cash and cash equivalents (a)	$	240	$	240	$	—	$	—	$	349	$	349	$	—	$	—
Restricted cash (b)	11		11		—		—		—		—		—		—
Long-term other assets (c)	156		1		103		49		110		1		58		50
Total	$	407	$	252	$	103	$	49	$	459	$	350	$	58	$	50
Liabilities
Fixed rate debt (d)	$	4,433	$	—	$	4,743	$	—	$	5,574	$	—	$	5,941	$	—
Floating rate debt (d)	4,655		—		4,562		—		3,986		—		3,997		—
Total	$	9,088	$	—	$	9,305	$	—	$	9,560	$	—	$	9,938	$	—


(a)	Cash and cash equivalents are comprised of cash on hand, and at November 30, 2013 also include time deposits. Due to their short maturities, the carrying values approximate their fair values.


(b)	Restricted cash is comprised of a money market deposit account.


(c)	At November 30, 2014 and 2013, long-term other assets were substantially all comprised of notes and other receivables. The fair values of our Level 1 and Level 2 notes and other receivables were based on estimated future cash flows discounted at appropriate market interest rates. The fair values of our Level 3 notes receivable were estimated using risk-adjusted discount rates.

(d)

Debt does not include the impact of interest rate swaps. The net difference between the fair value of our fixed rate debt and its carrying value was due to the market interest rates in existence at November 30, 2014 and 2013 being lower than the fixed interest rates on these debt obligations, including the impact of any changes in our credit ratings. At November 30, 2014 and 2013, the net difference between the fair value of our floating rate debt and its carrying value was due to the market interest rates in existence at November 30, 2014 and 2013 being slightly higher and slightly lower, respectively, than the floating interest rates on these debt obligations, including the impact of any changes in our credit ratings. The fair values of our publicly-traded notes were based on their unadjusted quoted market prices in markets that are not sufficiently active to be Level 1 and, accordingly, are considered Level 2. The fair values of our other debt were estimated based on appropriate market interest rates being applied to this debt.

Financial Instruments that are Measured at Fair Value on a Recurring Basis

The estimated fair value and basis of valuation of our financial instrument assets and liabilities that are measured at fair value on a recurring basis were as follows (in millions):



	November 30, 2014						November 30, 2013
	Level 1		Level 2		Level 3		Level 1		Level 2		Level 3
Assets
Cash equivalents (a)	$	91	$	—	$	—	$	113	$	—	$	—
Restricted cash (b)	19		—		—		28		—		—
Marketable securities held in rabbi trusts (c)	113		9		—		113		10		—
Derivative financial instruments (d)	—		14		—		—		60		—
Long-term other asset (e)	—		—		20		—		—		17
Total	$	223	$	23	$	20	$	254	$	70	$	17
Liabilities
Derivative financial instruments (d)	$	—	$	278	$	—	$	—	$	31	$	—
Total	$	—	$	278	$	—	$	—	$	31	$	—


(a)	Cash equivalents are comprised of money market funds.


(b)	The majority of restricted cash is comprised of money market funds.


(c)	At November 30, 2014 and 2013, marketable securities held in rabbi trusts were comprised of Level 1 bonds, frequently-priced mutual funds invested in common stocks, money market funds and Level 2 other investments. Their use is restricted to funding certain deferred compensation and non-qualified U.S. pension plans.


(d)	See “Derivative Instruments and Hedging Activities” section below for detailed information regarding our derivative financial instruments.


(e)	Long-term other asset is comprised of an auction-rate security. The fair value was based on a broker quote in an inactive market, which is considered a Level 3 input. During 2014, there were no purchases or sales pertaining to this auction-rate security and, accordingly, the change in its fair value was based solely on the strengthening of the underlying credit.

We measure our derivatives using valuations that are calibrated to the initial trade prices. Subsequent valuations are based on observable inputs and other variables included in the valuation models such as interest rate, yield and commodity price curves, forward currency exchange rates, credit spreads, maturity dates, volatilities and netting arrangements. We use the income approach to value derivatives for foreign currency options and forwards, interest rate swaps and fuel derivatives 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. We also corroborate our fair value estimates using valuations provided by our counterparties.

Nonfinancial Instruments that are Measured at Fair Value on a Nonrecurring Basis

Sales and Impairments of Ships

In November 2014, we sold the 672-passenger capacity Ocean Princess for a total gain of $24 million, of which $14 million was recognized in the fourth quarter of 2014 as a reduction in other ship operating expenses. We provided $66 million of financing to the buyer, which is due in semi-annual installments through November 2019. Prior to the ship’s delivery in March 2016, we will continue to operate it under a bareboat charter agreement. As a result of the sale-leaseback accounting for this transaction, the remaining gain of $10 million will be recognized as a reduction in other ship operating expenses over the term of the bareboat charter agreement through March 2016.

In November 2014, we entered into a bareboat charter/sale agreement under which the 1,440-passenger capacity Grand Holiday was chartered to an unrelated entity in January 2015 through March 2025. Under this agreement, ownership of Grand Holiday will be transferred to the buyer in March 2025. This transaction did not meet the criteria to qualify as a sales-type lease and, accordingly, it will be accounted for as an operating lease whereby we will recognize the charter revenue over the term of the agreement. As a result of this transaction, we performed a ship impairment review and recognized a $31 million impairment charge in other ship operating expenses during the fourth quarter of 2014. The estimated fair value of the ship was substantially all determined based on the expected collectability of the bareboat charter payments, which is considered a Level 3 input.

Due to the expected absorption of Ibero Cruises’ (“Ibero”) operations into Costa in November 2014, and certain ship specific facts and circumstances, such as size, age, condition, viable alternative itineraries and historical operating cash flows, we performed an undiscounted future cash flow analysis of Ibero’s Grand Celebration as of May 31, 2014 to determine if the ship was impaired. The principal assumptions used in our undiscounted cash flow analysis consisted of forecasted future operating results, including net revenue yields and net cruise costs including fuel prices, and the estimated residual value, which are all considered Level 3 inputs, and the then expected transfer of Grand Celebration into Costa in November 2014. Based on its undiscounted cash flow analysis, we determined that the net carrying value for Grand Celebration exceeded its estimated undiscounted future cash flows. Accordingly, we then estimated the May 31, 2014 fair value of this ship based on its discounted future cash flows and compared the estimated fair value to its net carrying value. As a result, we recognized a $22 million ship impairment charge in other ship operating expenses during the second quarter of 2014.

In December 2014, we entered into a bareboat charter/sale agreement under which the 1,492-passenger capacity Costa Celebration (formerly Grand Celebration) was chartered to an unrelated entity in December 2014 through December 2024. Under this agreement, ownership of Costa Celebration will be transferred to the buyer in December 2024. This transaction did not meet the criteria to qualify as a sales-type lease and, accordingly, it will be accounted for as an operating lease whereby we will recognize the charter revenue over the term of the agreement.

During the third quarter of 2013, we recognized $73 million and $103 million of impairment charges related to Costa Voyager and Costa Classica, respectively. In November 2013, Costa Voyager was taken out-of-service, and during the second quarter of 2014 Costa Voyager was sold and we recognized a $37 million gain as a reduction in other ship operating expenses. The estimated fair values of these ships at the time of impairment were based on their undiscounted cash flow analyses, which included principal assumptions similar to most of those discussed above for Grand Celebration.

During 2012, Costa Allegra suffered damage and, accordingly, we decided to withdraw this ship from operations resulting in a $34 million impairment charge, which is included in other ship operating expenses. In addition, during 2012, we incurred $17 million for Costa Allegra incident-related expenses, which are principally included in other ship operating expenses. In October 2012, we sold Costa Allegra. Furthermore, during 2012, we recognized $23 million of ship impairment charges related to Seabourn Legend and Seabourn Pride in other ship operating expenses. The estimated fair value for all three of these ships was determined based on their sales value, which is considered a Level 3 input.

In 2014, 2013 and 2012, we recognized $53 million, $176 million and $57 million, respectively, of ship impairment charges in other ship operating expenses.

Valuation of Goodwill and Other Intangibles

The reconciliation of the changes in the carrying amounts of our goodwill, which goodwill has been allocated to our North America and EAA cruise brands, was as follows (in millions):



	North America Cruise Brands		EAA Cruise Brands			Total
Balance at November 30, 2012	$	1,898	$	1,276		$	3,174
Foreign currency translation adjustment	—		36			36
Balance at November 30, 2013	1,898		1,312			3,210
Foreign currency translation adjustment	—		(83		)	(83		)
Balance at November 30, 2014	$	1,898	$	1,229		$	3,127

At July 31, 2014, all of our cruise brands carried goodwill, except for Ibero and Seabourn. As of that date, we performed our annual goodwill impairment reviews, which included performing a qualitative assessment for all cruise brands that carried goodwill, except for Carnival Cruise Line, Cunard and P&O Cruises (UK). Qualitative factors such as industry and market conditions, macroeconomic conditions, changes to the weighted-average cost of capital (“WACC”), overall financial performance, changes in fuel prices and capital expenditures were considered in the qualitative assessment to determine how changes in these factors would affect each of these cruise brands’ estimated fair values. Based on our qualitative assessments, we determined it was more-likely-than-not that each of these cruise brands’ estimated fair values exceeded their carrying values and, therefore, we did not proceed to the two-step quantitative goodwill impairment reviews.

As of July 31, 2014, we also performed our annual goodwill impairment reviews of Carnival Cruise Line’s, Cunard’s and P&O Cruises (UK)’s goodwill. We did not perform a qualitative assessment but instead proceeded directly to step one of the two-step quantitative goodwill impairment review and compared each of Carnival Cruise Line’s, Cunard’s and P&O Cruises (UK)’s estimated fair value to the carrying value of their allocated net assets. Their estimated cruise brand fair value was based on a discounted future cash flow analysis. The principal assumptions used in our cash flow analyses consisted of forecasted future operating results, including net revenue yields and net cruise costs including fuel prices; capacity changes, including the expected rotation of vessels into, or out of, Carnival Cruise Line, Cunard and P&O Cruises (UK); capital expenditures; WACC of market participants, adjusted for the risk attributable to the geographic regions in which Carnival Cruise Line, Cunard and P&O Cruises (UK) operate and terminal values, which are all considered Level 3 inputs. Based on the discounted cash flow analyses, we determined that each of Carnival Cruise Line’s, Cunard’s and P&O Cruises (UK)’s estimated fair value significantly exceeded their carrying value and, therefore, we did not proceed to step two of the impairment reviews.

At November 30, 2014, accumulated goodwill impairment charges were $153 million, which are all related to Ibero and were recognized in 2012.

The reconciliation of the changes in the carrying amounts of our intangible assets not subject to amortization, which represent trademarks that have been allocated to our North America and EAA cruise brands, was as follows (in millions):



	North America Cruise Brands		EAA Cruise Brands			Total
Balance at November 30, 2012	$	927	$	372		$	1,299
Ibero trademarks impairment charge (a)	—		(13		)	(13		)
Balance at November 30, 2013	927		359			1,286
Foreign currency translation adjustment	—		(21		)	(21		)
Balance at November 30, 2014	$	927	$	338		$	1,265


(a)	In 2013, we recognized a $13 million impairment charge to fully write-off Ibero’s trademarks’ carrying value.

At July 31, 2014, our cruise brands that have significant trademarks recorded include AIDA, P&O Cruises (Australia), P&O Cruises (UK) and Princess. As of that date, we performed our annual trademark impairment reviews for these cruise brands, which included performing a qualitative assessment for AIDA, P&O Cruises (Australia) and Princess. Qualitative factors such as industry and market conditions, macroeconomic conditions, changes to the WACC, changes in royalty rates and overall financial performance were considered in the qualitative assessment to determine how changes in these factors would affect the estimated fair values for each of these cruise brands’ recorded trademarks. Based on our qualitative assessments, we determined it was more likely-than-not that the estimated fair value for AIDA’s, P&O Cruises (Australia)’s and Princess’ recorded trademarks exceeded their carrying value and, therefore, none of these trademarks were impaired.

As of July 31, 2014, we also performed our annual trademark impairment review of P&O Cruises (UK). We did not perform a qualitative assessment but instead proceeded directly to the quantitative trademark impairment review. Our quantitative assessment included estimating P&O Cruises (UK)’s trademarks fair value based upon a discounted future cash flow analysis, which estimated the amount of royalties that we are relieved from having to pay for use of the associated trademarks, based upon forecasted cruise revenues and a market participant’s royalty rate. The royalty rate was estimated primarily using comparable royalty agreements for similar industries. Based on our quantitative assessment, we determined that the estimated fair value for P&O Cruises (UK)’s trademarks significantly exceeded their carrying values and, therefore, none of these trademarks were impaired.

In 2013, we recognized a $14 million impairment charge related to an investment, leaving an insignificant carrying value at November 30, 2014 and 2013. In 2012, we recognized a $20 million impairment charge to write-off a portion of Ibero’s trademarks’ carrying value.

At November 30, 2014 and 2013, our intangible assets subject to amortization are not significant to our consolidated financial statements.

The determination of our cruise brand, cruise ship and trademark fair values includes numerous assumptions that are subject to various risks and uncertainties. We believe that we have made reasonable estimates and judgments in determining whether our goodwill, cruise ships and trademarks have been impaired. However, if there is a change in assumptions used or if there is a change in the conditions or circumstances influencing fair values in the future, then we may need to recognize an impairment charge.

Derivative Instruments and Hedging Activities

We utilize derivative and nonderivative 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, and interest rate swaps to manage our interest rate exposure in order to achieve a desired proportion of fixed and floating rate debt. In addition, we utilize our fuel derivatives program to mitigate a portion of the risk to our future cash flows attributable to potential fuel price increases, which we define as our “economic risk.” Our policy is to not use any financial instruments for trading or other speculative purposes.

All derivatives are recorded at fair value. The changes in fair value are recognized currently in earnings if the derivatives do not qualify as effective hedges, or if we do not seek to qualify for hedge accounting treatment, such as for our fuel derivatives. If a derivative is designated as a fair value hedge, then changes in the fair value of the derivative are offset against the changes in the fair value of the underlying hedged item. If a derivative is designated as a cash flow hedge, then the effective portion of the changes 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 nonderivative financial instrument is designated as a hedge of our net investment in a foreign operation, then changes in the fair value of the financial instrument are recognized as a component of AOCI to offset a portion of the change in the translated value of the net investment being hedged, until the investment is sold or substantially liquidated. We formally document hedging relationships for all derivative and nonderivative hedges and the underlying hedged items, as well as our risk management objectives and strategies for undertaking the hedge transactions.

We classify the fair values of all our derivative contracts as either current or long-term, depending on whether the maturity date of the derivative contract is within or beyond one year from the balance sheet date. The cash flows from derivatives treated as hedges are classified in our Consolidated Statements of Cash Flows in the same category as the item being hedged. Our cash flows related to fuel derivatives are classified within investing activities.

(a)	At November 30, 2014 and 2013, we had foreign currency forwards totaling $403 million and $578 million, respectively, that are designated as hedges of our net investments in foreign operations, which have a euro-denominated functional currency. At November 30, 2014, these foreign currency forwards settle through July 2017.


(b)	At November 30, 2014 and 2013, we had foreign currency derivatives consisting of foreign currency zero cost collars that are designated as foreign currency cash flow hedges for a portion of our euro-denominated shipbuilding payments. See “Newbuild Currency Risks” below for additional information regarding these derivatives.

(c)

We have euro interest rate swaps designated as cash flow hedges whereby we receive floating interest rate payments in exchange for making fixed interest rate payments. At November 30, 2014 and 2013, these interest rate swap agreements effectively changed $750 million and $909 million, respectively, of EURIBOR-based floating rate euro debt to fixed rate euro debt. These interest rate swaps settle through March 2025. In addition, at November 30, 2014 and 2013 we had U.S. dollar interest rate swaps designated as fair value hedges whereby we receive fixed interest rate payments in exchange for making floating interest rate payments. At November 30, 2014 and 2013, these interest rate swap agreements effectively changed $500 million of fixed rate debt to U.S. dollar LIBOR-based floating rate debt. These interest rate swaps settle through February 2016.


(d)	At November 30, 2014 and 2013, we had fuel derivatives consisting of zero cost collars on Brent crude oil (“Brent”) to cover a portion of our estimated fuel consumption through 2018 and through 2017, respectively. See “Fuel Price Risks” below for additional information regarding these fuel derivatives.

Our derivative contracts include rights of offset with our counterparties. We have elected to net certain of our derivative assets and liabilities within counterparties. The amounts recognized within assets and liabilities were as follows (in millions):



	November 30, 2014
	Gross Amounts		Gross Amounts Offset in the Balance Sheet			Total Net Amounts Presented in the Balance Sheet		Gross Amounts not Offset in the Balance Sheet			Net Amounts
Assets	$	78	$	(64	)	$	14	$	(14	)	$	—

Liabilities	$	108	$	(77	)	$	31	$	(7	)	$	24

The effective portions of our derivatives qualifying and designated as hedging instruments recognized in other comprehensive (loss) income were as follows (in millions):



	November 30,
	2014			2013			2012
Net investment hedges	$	25		$	(11	)	$	48
Foreign currency zero cost collars – cash flow hedges	$	(10	)	$	(1	)	$	16
Interest rate swaps – cash flow hedges	$	(28	)	$	2		$	(11	)

There are no credit risk related contingent features in our derivative agreements, except for bilateral credit provisions within our fuel derivative counterparty agreements. These provisions require interest-bearing, non-restricted cash to be posted or received as collateral to the extent the fuel derivative fair value payable to or receivable from an individual counterparty, respectively, exceeds $100 million. At November 30, 2014 and 2013, no collateral was required to be posted to or received from our fuel derivative counterparties.

The amount of estimated cash flow hedges’ unrealized gains and losses that are expected to be reclassified to earnings in the next twelve months is not significant. We have not provided additional disclosures of the impact that derivative instruments and hedging activities have on our consolidated financial statements as of November 30, 2014 and 2013 and for the years ended November 30, 2014, 2013 and 2012 where such impacts were not significant.

Fuel Price Risks

Our exposure to market risk for changes in fuel prices substantially all relates to the consumption of fuel on our ships. We use our fuel derivatives program to mitigate a portion of our economic risk attributable to potential fuel price increases. We designed our fuel derivatives program to maximize operational flexibility by utilizing derivative markets with significant trading liquidity and our program currently consists of zero cost collars on Brent.

All of our derivatives are based on Brent prices whereas the actual fuel used on our ships is marine fuel. Changes in the Brent prices may not show a high degree of correlation with changes in our underlying marine fuel prices. We will not realize any economic gain or loss upon the monthly maturities of our zero cost collars unless the average monthly price of Brent is above the ceiling price or below the floor price. We believe that these derivatives will act as economic hedges; however, hedge accounting is not applied. As part of our fuel derivatives program, we will continue to evaluate various derivative products and strategies. In 2014, 2013 and 2012, our unrealized (losses) gains, net on fuel derivatives were $(268) million, $36 million and $6 million, respectively, and in 2014 and 2012, our realized losses, net were $(3) million and $(13) million, respectively. There were no realized gains or losses in 2013.

At November 30, 2014, our outstanding fuel derivatives consisted of zero cost collars on Brent to cover a portion of our estimated fuel consumption as follows:



Maturities (a)	Transaction Dates	Barrels (in thousands)	Weighted-Average Floor Prices		Weighted-Average Ceiling Prices		Percent of Estimated Fuel Consumption Covered

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 nonderivative financial instruments. Our primary focus is to manage the economic foreign currency exchange risks faced by our operations, which are the ultimate foreign currency exchange risks that would be realized by us if we exchanged one currency for another, and not accounting risks. While we will continue to monitor our exposure to these economic risks, we do not currently hedge our foreign currency exchange risks with derivative or nonderivative financial instruments, with the exception of certain of our ship commitments and net investments in foreign operations. The financial impacts of the hedging instruments we do employ generally offset the changes in the underlying exposures being hedged.

Operational Currency Risks

Our European and Australian cruise brands generate significant revenues and incur significant expenses in their euro, sterling or Australian dollar functional currency, which subjects us to "foreign currency translational" risk related to these currencies. Accordingly, exchange rate fluctuations of the euro, sterling and Australian dollar against the U.S. dollar will affect our reported financial results since the reporting currency for our consolidated financial statements is the U.S. dollar. Any strengthening of the U.S. dollar against these foreign currencies has the financial statement effect of decreasing the U.S. dollar values reported for these cruise brands’ revenues and expenses. Any weakening of the U.S. dollar has the opposite effect.

Most of our brands also have non-functional currency risk related to their international sales operations, which has become an increasingly larger part of most of their businesses over time, and principally includes the euro, sterling and Australian and U.S. dollars. In addition, all of our brands have non-functional currency expenses for a portion of their operating expenses. Accordingly, we also have "foreign currency transactional" risks related to changes in the exchange rates for our brands’ revenues and expenses that are in a currency other than their functional currency. However, these brands’ revenues and expenses in non-functional currencies create some degree of natural offset from these currency exchange movements. In addition, we monitor this foreign currency transactional risk in order to measure its impact on our results of operations.

Investment Currency Risks

We consider our investments in foreign operations to be denominated in relatively stable currencies and of a long-term nature. We partially mitigate our net investment currency exposures by denominating a portion of our foreign currency intercompany payables in our foreign operations’ functional currencies, substantially all sterling. As of November 30, 2014 and 2013, we have designated $2.4 billion and $2.2 billion, respectively, of our foreign currency intercompany payables as nonderivative hedges of our net investments in foreign operations. Accordingly, we have included $359 million and $234 million of cumulative foreign currency transaction nonderivative gains in the cumulative translation adjustment component of AOCI at November 30, 2014 and 2013, respectively, which offsets a portion of the losses recorded in AOCI upon translating our foreign operations’ net assets into U.S. dollars. During 2014, 2013 and 2012, we recognized foreign currency nonderivative transaction gains (losses) of $125 million, $(9) million and $39 million, respectively, in the cumulative translation adjustment component of AOCI.

Newbuild Currency Risks

Our shipbuilding contracts are typically denominated in euros. Our decisions regarding whether or not to hedge a non-functional currency ship commitment for our cruise brands are made on a case-by-case basis, taking into consideration the amount and duration of the exposure, market volatility, economic trends, our overall expected net cash flows by currency and other offsetting risks. We use foreign currency derivative contracts and have used nonderivative financial instruments to manage foreign currency exchange rate risk for some of our ship construction payments.

In July 2012, we entered into foreign currency zero cost collars that are designated as cash flow hedges for a portion of P&O Cruises (UK) Britannia’s euro-denominated shipyard payments. These collars mature in February 2015 at a weighted-average ceiling of $287 million and a weighted-average floor of $266 million. In June 2014, we entered into additional foreign currency zero cost collars that are also designated as cash flow hedges for the remaining portion of Britannia’s euro-denominated shipyard payments. These collars also mature in February 2015 at a weighted-average ceiling of $281 million and a weighted-average floor of $274 million. If the spot rate is between the weighted-average ceiling and floor rates on the date of maturity, then we would not owe or receive any payments under these collars.

On January 22, 2015, we entered into foreign currency zero cost collars that are designated as cash flow hedges for a portion of a Princess and Seabourn newbuilds’ euro-denominated shipyard payments. The Princess newbuild’s collars mature in March 2017 at a weighted-average ceiling of $590 million and a weighted-average floor of $504 million. The Seabourn newbuild’s collars mature in November 2016 at a weighted-average ceiling of $221 million and a weighted-average floor of $185 million. If the spot rate is between the weighted-average ceiling and floor rates on the date of maturity, then we would not owe or receive any payments under these collars.

At January 22, 2015, substantially all of our remaining newbuild currency exchange rate risk relates to euro-denominated newbuild construction payments for a Carnival Cruise Line, Holland America Line and Seabourn newbuild, which represent a total unhedged commitment of $1.7 billion.

The cost of shipbuilding orders that we may place in the future that is denominated in a different currency than our cruise brands’ or the shipyards’ functional currency is expected to be affected by foreign currency exchange rate fluctuations. These foreign currency exchange rate fluctuations may affect our desire to order new cruise ships.

Interest Rate Risks

We manage our exposure to fluctuations in interest rates through our debt portfolio management and investment strategies. We evaluate our debt portfolio to determine whether to make periodic adjustments to the mix of fixed and floating rate debt through the use of interest rate swaps and the issuance of new debt or the early retirement of existing debt. At November 30, 2014, 52% and 48% (59% and 41% at November 30, 2013) of our debt bore fixed and floating interest rates, respectively, including the effect of interest rate swaps. In addition, to the extent that we have excess cash available for investment, we purchase high quality short-term investments with floating interest rates, which offset a portion of the impact of interest rate fluctuations arising from our floating interest rate debt portfolio.

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. Our maximum exposure under foreign currency and fuel derivative contracts and interest rate swap agreements that are in-the-money, which were not material at November 30, 2014, is the replacement cost, net of any collateral received or contractually allowed offset, in the event of nonperformance by the counterparties to the contracts, all of which are currently our lending banks. We seek to minimize credit risk exposure, including counterparty nonperformance primarily associated with our cash equivalents, investments, committed financing facilities, contingent obligations, derivative instruments, insurance contracts and new ship progress payment guarantees, by normally conducting business with large, well-established financial institutions, insurance companies and export credit agencies, and by diversifying our counterparties. In addition, we have guidelines regarding credit ratings and investment maturities that we follow to help safeguard liquidity and minimize risk. We normally do require collateral and/or guarantees to support notes receivable on significant asset sales, long-term ship charters and new ship progress payments to shipyards. We currently believe the risk of nonperformance by any of our significant counterparties is remote.

We also monitor the creditworthiness of travel agencies and tour operators in Asia, Australia and Europe and credit and debit card providers to which we extend credit in the normal course of our business, which includes charter-hire agreements in Asia prior to sailing. Our credit exposure also includes contingent obligations related to cash payments received directly by travel agents and tour operators for cash collected by them on cruise sales in Australia and most of Europe where we are obligated to honor our guests' cruise payments made by them to their travel agents and tour operators regardless of whether we have received these payments. Concentrations of credit risk associated with these receivables, charter-hire agreements and contingent obligations are not considered to be material, primarily due to the large number of unrelated accounts within our customer base, the amount of these contingent obligations and their short maturities. We have experienced only minimal credit losses on our trade receivables and related contingent obligations. We do not normally require collateral or other security to support normal credit sales.

Segment Reporting [Abstract]

Segment Information

We have three reportable cruise segments that are comprised of our (1) North America cruise brands, (2) EAA cruise brands and (3) Cruise Support. In addition, we have a Tour and Other segment. Our segments are reported on the same basis as the internally reported information that is provided to our chief operating decision maker (“CODM”), who is the President and Chief Executive Officer of Carnival Corporation and Carnival plc. Decisions to allocate resources and assess performance for Carnival Corporation & plc are made by the CODM upon review of the segment results across all of our cruise brands and other segments.

Our North America cruise segment includes Carnival Cruise Line, Holland America Line, Princess and Seabourn. Our EAA cruise segment includes AIDA, Costa, Cunard, P&O Cruises (Australia), P&O Cruises (UK) and prior to November 2014, Ibero. These individual cruise brand operating segments have been aggregated into two reportable segments based on the similarity of their economic and other characteristics, including types of customers, regulatory environment, ship maintenance requirements, supporting systems and processes and products and services they provide. Our Cruise Support segment represents certain of our port and related facilities and other services that are provided for the benefit of our cruise brands. Our Tour and Other segment represents the hotel and transportation operations of Holland America Princess Alaska Tours. In 2012, our Tour and Other segment also included two ships that we chartered to an unaffiliated entity. In April 2013, we sold one of these two ships and recognized a $15 million gain as a reduction of Tour and Other operating expenses. Accordingly, subsequent to this 2013 sale and through November 30, 2014, our Tour and Other segment included only one ship. The significant accounting policies of our segments are the same as those described in Note 2 – “Summary of Significant Accounting Policies.”

Selected information for our segments as of and for the years ended November 30 was as follows (in millions):

(a)

A portion of the North America cruise brands’ segment revenues includes revenues for the tour portion of a cruise when a land tour package is sold along with a cruise by either Holland America Line or Princess. These intersegment tour revenues, which are included in our Tour and Other segment, are eliminated directly against the North America cruise brands’ segment revenues and operating expenses in the line “Intersegment elimination.”


(b)	Includes $13 million in 2013 and $173 million in 2012 of impairment charges related to Ibero’s goodwill and trademarks.


(c)	Tour and Other segment assets primarily include hotels and lodges in the state of Alaska and the Canadian Yukon, motorcoaches used for sightseeing and charters, glass-domed railcars, which run on the Alaska Railroad, and our owned ships that we leased out under long-term charters to an unaffiliated entity.

Non-U.S. revenues for our cruise brands represent sales generated from outside the U.S. principally by non-U.S. travel agents and tour operators. Substantially all of our long-lived assets are located outside of the U.S. and consist of our ships and ships under construction.

Revenues by geographic areas, which are based on where our guests are sourced and not the cruise brands on which they sailed, were as follows (in millions):

Compensation Plans

Equity Plans

We issue our share-based compensation awards under the Carnival Corporation and Carnival plc stock plans, which have an aggregate of 18.6 million shares available for future grant at November 30, 2014. These plans allow us to issue time-based share (“TBS”) awards, which include restricted stock awards (“RSAs”) and restricted stock units (“RSUs”), performance-based share (“PBS”) awards, market-based share (“MBS”) awards and stock options (collectively “equity awards”). Equity awards are principally granted to management level employees and members of our Boards of Directors. The plans are administered by a committee of our independent directors (the “Committee”) that determines 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. These plans allow us to fulfill our equity award obligations using shares purchased in the open market or with unissued or treasury shares. Certain equity awards provide for accelerated vesting if we have a change in control, as defined.

Our total share-based compensation expense was $52 million, $42 million and $39 million in 2014, 2013 and 2012, respectively, of which $48 million, $39 million and $36 million has been included in selling and administrative expenses in 2014, 2013 and 2012, respectively, and $4 million in 2014 and $3 million in both 2013 and 2012 in cruise payroll and related expenses.

TBS, PBS and MBS Awards

RSAs generally have the same rights as Carnival Corporation common stock, except for transfer restrictions and forfeiture provisions. RSAs have been granted to certain officers and non-executive board members and vest at the end of three years, except for shares released from restriction to satisfy retirement eligible tax obligations (“tax release shares”). In addition, Carnival Corporation and Carnival plc grant RSUs, which also vest at the end of three years, except for tax release shares, and accrue forfeitable dividend equivalents on each outstanding RSU, in the form of additional RSUs, based on dividends declared. The share-based compensation expense for TBS awards is based on the quoted market price of the Carnival Corporation or Carnival plc shares on the date of grant.

In 2014 and 2013, the Committee approved PBS awards to be granted to certain key Carnival Corporation & plc executives. The share-based compensation expense for these PBS awards is based on the quoted market price of the Carnival Corporation or Carnival plc shares and expected total shareholder return rank relative to certain peer companies on the date of grant and the probability of our annual earnings target for each year over a three-year period being achieved. Our 2014 PBS awards also have a return on invested capital ("ROIC") target. The PBS awards granted in 2014 and 2013 provide an opportunity to earn from zero to 200% and zero to 187.5%, respectively, of the number of target shares underlying the award achieved for each year over a three-year period.

In 2012, the Committee approved PBS awards to be granted to certain key Carnival Corporation & plc executives. The share-based compensation expense for these PBS awards is based on the quoted market price of the Carnival Corporation or Carnival plc shares on the date of grant and the probability of our earnings per share growth over a three-year period being achieved. These PBS awards provide an opportunity to earn from zero to 200% of the number of target shares underlying the award achieved at the end of the third year. All PBS awards will accrue forfeitable dividend equivalents based on dividends declared.

In 2014 and 2013, the Committee approved MBS awards to be granted to certain senior executives. The MBS awards granted in 2014 and 2013 were valued at $13 million and $4 million, respectively, as of the date of grant. The share-based compensation expense for all of the MBS awards were based on the quoted market prices of the Carnival Corporation common stock or the Carnival plc ordinary shares on the date of grant and the probability of certain market conditions being achieved. One-half of all of the MBS awards are expensed evenly over a three-year period and the remaining half are expensed evenly over a four-year period.

During the year ended November 30, 2014, TBS, PBS and MBS award activity was as follows:



	TBS Awards				PBS Awards				MBS Awards
	Shares		Weighted-Average Grant Date Fair Value		Shares		Weighted-Average Grant Date Fair Value		Shares	Weighted-Average Grant Date Fair Value
Outstanding at November 30, 2013	3,026,701		$	37.01	510,839		$	35.91	93,457	$	47.03

Outstanding at November 30, 2014	3,210,050		$	36.30	572,787		$	34.82	270,220	$	64.11

The total grant date fair value of TBS, PBS and MBS awards vested was $41 million, $42 million and $52 million in 2014, 2013 and 2012, respectively. As of November 30, 2014, there was $55 million of total unrecognized compensation cost related to TBS, PBS and MBS awards. As of November 30, 2014, the total unrecognized compensation costs are expected to be recognized over a weighted-average period of 0.9 years for both TBS and PBS awards and 1.5 years for MBS awards.

Stock Option Plans

In 2007 and 2008, the Committee decided to cease granting stock options to our employees and non-executive board members, respectively, and to instead grant them TBS awards. A combined summary of Carnival Corporation and Carnival plc stock option activity during the year ended November 30, 2014 related to stock options previously granted was as follows:



	Shares		Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term	Aggregate Intrinsic Value (a)
					(in years)	(in millions)
Outstanding at November 30, 2013	3,922,172		$	48.42
Exercised	(17,889	)	$	39.87
Forfeited or expired	(2,845,027	)	$	46.88
Outstanding and exercisable at November 30, 2014	1,059,256		$	51.36	0.4	$	—


(a)	The aggregate intrinsic value represents the amount by which the fair value of underlying stock exceeds the option exercise price at November 30, 2014.

As of the dates of exercise, there was a nominal intrinsic value of options exercised in 2014 and a total of $3 million and $7 million in 2013 and 2012, respectively. As of November 30, 2014, there is no unrecognized compensation cost as there were no unvested stock options. Our stock options will expire through 2016.

Defined Benefit Pension Plans

We have several single-employer defined benefit pension plans, which cover some 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. Substantially all of the remaining defined benefit plans are unfunded. In determining all of our plans’ benefit obligations at November 30, 2014 and 2013, we assumed weighted-average discount rates of 3.5% and 4.0%, respectively. The net asset or net liability positions under these single-employer defined benefit pension plans are not material.

In addition, we participate in two multiemployer defined benefit pension plans in the UK, the British Merchant Navy Officers Pension Fund (registration number 10005645) (“MNOPF”), and the British Merchant Navy Ratings Pension Fund (registration number 10005646) (“MNRPF”), which are referred to as “the multiemployer plans.” The MNOPF is divided into two sections, the “New Section” and the “Old Section.” The multiemployer plans are maintained for the benefit of the employees of the participating employers who make contributions to the plans. However, contributions made by employers, including us, may be used to provide benefits to employees of other participating employers, and if any of the participating employers 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 the MNOPF Old Section is also closed to further benefit accrual and is fully funded. Based on the most recent actuarial reviews of the MNOPF New Section and the MNRPF at March 31, 2014 and March 31, 2013, respectively, it was determined that these plans were 87% and 74% funded, respectively. The multiemployer plans have implemented recovery plans, as appropriate, whereby their estimated funding deficits are to be recovered through funding contributions from participating employers.

We expense our portion of the MNOPF deficit as amounts are invoiced by, and become due and payable to, the trustees. In 2014 and 2012, our contributions to the MNOPF fund were not material and did not exceed 5% of total contributions to the fund. In 2013, we received and paid in full a special assessment invoice from the MNOPF trustee for our additional share of the MNOPF New Section deficit. Accordingly, we expensed the invoice of $15 million in cruise payroll and related expense in 2013, which exceeded 5% of total contributions to the fund. In addition, we accrue and expense our portion of the MNRPF deficit based on our estimated probable obligation from the most recent actuarial review. In 2014, we expensed $18 million of our estimated probable obligation relating to our allocated share of the MNRPF deficit in cruise payroll and related expenses. As of November 30, 2014, our remaining estimated obligation of the MNRPF deficit was $13 million after contributing $24 million in 2014. In 2014, our contributions to the MNRPF are expected to exceed 5% of total contributions to the fund. In 2013 and 2012, our contributions to the MNRPF were not material and 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.

Total expense for all defined benefit pension plans, including the multiemployer plans, was $69 million, $62 million and $45 million in 2014, 2013 and 2012, respectively.

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 $25 million in both 2014 and 2013 and $22 million in 2012.

Their use is restricted to funding certain deferred compensation and non-qualified U.S. pension plans.


(d)	See “Derivative Instruments and Hedging Activities” section below for detailed information regarding our derivative financial instruments.


(e)	Long-term other asset is comprised of an auction-rate security. The fair value was based on a broker quote in an inactive market, which is considered a Level 3 input. During 2014, there were no purchases or sales pertaining to this auction-rate security and, accordingly, the change in its fair value was based solely on the strengthening of the underlying credit.

At November 30, 2014, 52% and 48% (59% and 41% at November 30, 2013) of our debt bore fixed and floating interest rates, respectively, including the effect of interest rate swaps. Substantially all of our fixed rate debt can only be called or prepaid by incurring additional costs. In addition, substantially all of our debt agreements, including our main revolving credit facility, contain one or more financial covenants that require us, among other things, to maintain minimum debt service coverage and minimum shareholders’ equity and to limit our debt to capital and debt to equity ratios and the amounts of our secured assets and secured and other indebtedness. Generally, if an event of default under any debt agreement occurs, then pursuant to cross default acceleration clauses, substantially all of our outstanding debt and derivative contract payables (see Note 10) could become due, and all debt and derivative contracts could be terminated. At November 30, 2014, we believe we were in compliance with all of our debt covenants.
[2]	Includes $2.4 billion of debt whose interest rates, and in the case of our main revolver its commitment fees, would increase upon a downgrade in the long-term senior unsecured credit ratings of Carnival Corporation or Carnival plc.
[3]	In 2014, we borrowed $498 million under a euro-denominated export credit facility, the proceeds of which were used to pay for a portion of Costa Diadema's purchase price and is due in semi-annual installments through October 2026.
[4]	In 2014, we repaid an aggregate of $590 million outstanding under two export credit facilities prior to their maturities through May 2024. In addition, in 2014 we borrowed $554 million under an export credit facility, the proceeds of which were used to pay for a portion of Regal Princess’ purchase price and is due in semi-annual installments through May 2026.
[5]	In 2014, we restructured two floating rate bank loan facilities that had an aggregate outstanding balance of $250 million and were previously due through 2016. The restructuring converted the terms into perpetual one-year maturities and added a $150 million tranche, which was used to repay a portion of a $500 million fixed rate bank loan in 2014 prior to its 2015 maturity date. We can terminate this facility at any time upon three days notice, and the bank can terminate the facility at any time upon one-year’s notice.
[6]	In 2014, we borrowed $150 million under a floating rate bank loan, which is due in September 2019. We used the net proceeds of this loan for general corporate purposes.
[7]	In 2014, we borrowed $275 million under a euro-denominated floating rate revolving bank loan facility, the proceeds of which were used for general corporate purposes. This facility has a perpetual term although we can terminate it at any time, and the bank can terminate the facility at any time upon nine months notice.
[8]	The interest rate associated with our short-term borrowings represents an aggregate-weighted average interest rate.

[3]	The net difference between the fair value of our fixed rate debt and its carrying value was due to the market interest rates in existence at November 30, 2014 and 2013 being lower than the fixed interest rates on these debt obligations, including the impact of any changes in our credit ratings. At November 30, 2014 and 2013, the net difference between the fair value of our floating rate debt and its carrying value was due to the market interest rates in existence at November 30, 2014 and 2013 being slightly higher and slightly lower, respectively, than the floating interest rates on these debt obligations, including the impact of any changes in our credit ratings. The fair values of our publicly-traded notes were based on their unadjusted quoted market prices in markets that are not sufficiently active to be Level 1 and, accordingly, are considered Level 2. The fair values of our other debt were estimated based on appropriate market interest rates being applied to this debt.

[1]	At November 30, 2014 and 2013, we had foreign currency forwards totaling $403 million and $578 million, respectively, that are designated as hedges of our net investments in foreign operations, which have a euro-denominated functional currency. At November 30, 2014, these foreign currency forwards settle through July 2017.
[2]	At November 30, 2014 and 2013, we had foreign currency derivatives consisting of foreign currency zero cost collars that are designated as foreign currency cash flow hedges for a portion of our euro-denominated shipbuilding payments. See “Newbuild Currency Risks” below for additional information regarding these derivatives.
[3]	We have euro interest rate swaps designated as cash flow hedges whereby we receive floating interest rate payments in exchange for making fixed interest rate payments. At November 30, 2014 and 2013, these interest rate swap agreements effectively changed $750 million and $909 million, respectively, of EURIBOR-based floating rate euro debt to fixed rate euro debt. These interest rate swaps settle through March 2025. In addition, at November 30, 2014 and 2013 we had U.S. dollar interest rate swaps designated as fair value hedges whereby we receive fixed interest rate payments in exchange for making floating interest rate payments. At November 30, 2014 and 2013, these interest rate swap agreements effectively changed $500 million of fixed rate debt to U.S. dollar LIBOR-based floating rate debt. These interest rate swaps settle through February 2016.
[4]	At November 30, 2014 and 2013, we had fuel derivatives consisting of zero cost collars on Brent crude oil (“Brent”) to cover a portion of our estimated fuel consumption through 2018 and through 2017, respectively. See “Fuel Price Risks” below for additional information regarding these fuel derivatives.

[1]	A portion of the North America cruise brands’ segment revenues includes revenues for the tour portion of a cruise when a land tour package is sold along with a cruise by either Holland America Line or Princess. These intersegment tour revenues, which are included in our Tour and Other segment, are eliminated directly against the North America cruise brands’ segment revenues and operating expenses in the line “Intersegment elimination.”
[2]	Includes $13 million in 2013 and $173 million in 2012 of impairment charges related to Ibero’s goodwill and trademarks.
[3]	The net difference between the fair value of our fixed rate debt and its carrying value was due to the market interest rates in existence at November 30, 2014 and 2013 being lower than the fixed interest rates on these debt obligations, including the impact of any changes in our credit ratings. At November 30, 2014 and 2013, the net difference between the fair value of our floating rate debt and its carrying value was due to the market interest rates in existence at November 30, 2014 and 2013 being slightly higher and slightly lower, respectively, than the floating interest rates on these debt obligations, including the impact of any changes in our credit ratings. The fair values of our publicly-traded notes were based on their unadjusted quoted market prices in markets that are not sufficiently active to be Level 1 and, accordingly, are considered Level 2. The fair values of our other debt were estimated based on appropriate market interest rates being applied to this debt.
[4]	Tour and Other segment assets primarily include hotels and lodges in the state of Alaska and the Canadian Yukon, motorcoaches used for sightseeing and charters, glass-domed railcars, which run on the Alaska Railroad, and our owned ships that we leased out under long-term charters to an unaffiliated entity
