(2)Inputs other than quoted prices included within Level 1 that are observable for the liability, either directly or indirectly. For unsecured revolving credit facilities and unsecured term loans, fair value is determined utilizing the income valuation approach. This valuation model takes into account the contract terms of our debt such as the debt maturity and the interest rate on the debt. The valuation model also takes into account the creditworthiness of the Company.

(2)Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. For foreign currency forward contracts, interest rate swaps and fuel swaps, fair value is derived using valuation models that utilize the income valuation approach. These valuation models take into account the contract terms, such as maturity as well as other inputs, such as foreign exchange rates and curves, fuel types, fuel curves and interest rate yield curves. Derivative instrument fair values take into account the creditworthiness of the counterparty and the Company.

(6)Any obligation under the contingent consideration related to the 2018 Silversea Cruises acquisition was terminated during the quarter ended September 30, 2020 as a result of our purchase of the remaining 33.3% non-controlling interest in Silversea Cruises. In prior periods, the contingent consideration was estimated by applying a Monte-Carlo simulation method using our closing stock price along with significant inputs not observable in the market, including the probability of achieving the milestones and estimated future operating results. The Monte-Carlo simulation is a generally accepted statistical technique used to generate a defined number of valuation paths in order to develop a reasonable estimate of fair value. Refer to Note 1. General, Note 3. Business Combination, and Note 11. Redeemable Noncontrolling Interest for further information on the Silversea Cruises acquisitions. For the twelve months ended December 31, 2020, we recorded income for the change in fair value of the contingent consideration of $45.1 million within Other (expense) income in our consolidated statements of comprehensive income (loss).

The reported fair values are based on a variety of factors and assumptions. Accordingly, the fair values may not represent actual values of the financial instruments that could have been realized as of December 31, 2020 or 2019, or that will be realized in the future, and do not include expenses that could be incurred in an actual sale or settlement.

(1) We estimated the fair value of the Silversea Cruises reporting unit using a probability-weighted discounted cash flow model in combination with a market based valuation approach. The principal assumptions used in the discounted cash flow model were (i) the timing of our return to service, changes in market conditions and port or other restrictions; (ii) forecasted net revenues, primarily the timing of returning to normalized operations, occupancy rates from existing and expected ship deliveries, including options, and terminal growth rate; and (iii) weighted average cost of capital (i.e., discount rate). The discounted cash flow model used our 2020 projected operating results as a base. To that base we added future years’ cash flows through 2030 assuming multiple revenue and expense scenarios that reflect the impact of different global economic environments for this period on the Silversea Cruises' reporting unit. We assigned a probability to each revenue and expense scenario. We discounted the projected cash flows using rates specific to the Silversea Cruises' reporting unit based on its weighted-average cost of capital, which was determined to be 12.75%. The fair value of Silversea Cruises’ goodwill was estimated as of March 31, 2020, the date the asset was last impaired.

(2) Amount represents the Silversea Cruises trade name which makes up the majority of our indefinite-life intangible assets, totaling $321.5 million. We estimated the fair value of our the Silversea Cruises trade name using a discounted cash flow model and the relief-from-royalty method and used a discount rate of 13.25%. Significant inputs in performing the fair value assessment for the trade name were (i) forecasted net revenues, primarily the timing of returning to normalized operations, occupancy rates from existing and expected ship deliveries, including options, and terminal growth rate; (ii) the royalty rate of 3.0%; and (iii) weighted average cost of capital (i.e., discount rate). The fair value of the Silversea Cruises trade name was estimated as of March 31, 2020, the date the asset was last impaired.

(3) Impairments primarily relate to certain vessels during 2020. In addition, certain construction in progress projects generated impairments during the quarter ended September 30, 2020 and quarter ended December 31, 2020. For the vessels impaired during the quarter ended March 31, 2020, we estimated the fair value of two of our vessels using a blended indication from the income and cost approaches and the fair value of the remaining vessels was estimated primarily based on their orderly liquidation values. For the vessels impaired during the quarter ended June 30, 2020, we estimated the fair value of the vessels using a modified market approach based on the carrying values and orderly liquidation values of the vessels. For the vessels impaired during the quarter ended December 31, 2020, we estimated the fair value of the three Azamara vessels using a market approach. A significant input in performing the fair value assessments for these vessels was management's expected use of the vessels, which takes into consideration forecasted operating results. During the quarter ended September 30, 2020 and quarter ended December 31, 2020, construction in progress assets were impaired due to a reduction in scope or the decision to not complete the projects. The impairment was calculated based on orderly liquidation values. The fair value of these assets were estimated as of the date the asset was last impaired.

(4) Impairments to our right-of-use assets relate to certain of our berthing arrangements and a ship operating lease. We estimated the fair value of the berthing arrangements using estimated projected discounted cash flows and the fair value of the ship operating lease was estimated using a market approach. The fair value of the berthing arrangements was estimated as of March 31, 2020, the date these assets were last impaired. A significant input in performing the fair value assessments for these assets was our expected passenger headcount. The fair value of the ship operating lease was estimated as of December 31, 2020, the date this asset was last impaired, and significant inputs in performing the fair value assessment using the market approach for this asset were the expected rate of return and remaining lease payments.

(5) We estimated the fair value of our other than temporarily impaired equity-method investments using a discounted cash flow model. A significant input in performing the fair value assessments for these assets was forecasted operating results for these investments. The fair value of these equity-method investments was estimated as of March 31, 2020, the date these assets were last impaired. For further information on our equity method investments, refer to Note 8. Other Assets.

We have master International Swaps and Derivatives Association (“ISDA”) agreements in place with our derivative instrument counterparties. These ISDA agreements generally provide for final close out netting with our counterparties for all positions in the case of default or termination of the ISDA agreement. We have determined that our ISDA agreements provide us with rights of setoff on the fair value of derivative instruments in a gain position and those in a loss position with the same counterparty. We have elected not to offset such derivative instrument fair values in our consolidated balance sheets.

We monitor our credit risk associated with financial and other institutions with which we conduct significant business and, to minimize these risks, we select counterparties with credit risks acceptable to us and we seek to limit our exposure to an individual counterparty. Credit risk, including but not limited to counterparty nonperformance under derivative instruments, our credit facilities and new ship progress payment guarantees, is not considered significant, as we primarily conduct business with large, well-established financial institutions, insurance companies and export credit agencies many of which we have long-term relationships with and which have credit risks acceptable to us or where the credit risk is spread out among a large number of counterparties. As of December 31, 2020, we had counterparty credit risk exposure under our derivative instruments of $26.9 million, which was limited to the cost of replacing the contracts in the event of non-performance by the counterparties to the contracts, the majority of which are currently our lending banks. We do not anticipate nonperformance by any of our significant counterparties. In addition, we have established guidelines we follow regarding credit ratings and instrument maturities to maintain safety and liquidity. We do not normally require collateral or other security to support credit relationships; however, in certain circumstances this option is available to us.

We are exposed to market risk attributable to changes in interest rates, foreign currency exchange rates and fuel prices. We try to mitigate these risks through a combination of our normal operating and financing activities and through the use of derivative financial instruments pursuant to our hedging practices and policies. The financial impact of these hedging instruments is primarily offset by corresponding changes in the underlying exposures being hedged. We achieve this by closely matching the notional amount, term and conditions of the derivative instrument with the underlying risk being hedged. Although certain of our derivative financial instruments do not qualify or are not accounted for under hedge accounting, our objective is not to hold or issue derivative financial instruments for trading or other speculative purposes.

We enter into various forward, swap and option contracts to manage our interest rate exposure and to limit our exposure to fluctuations in foreign currency exchange rates and fuel prices. These instruments are recorded on the balance sheet at their fair value and the vast majority are designated as hedges. We also use non-derivative financial instruments designated as hedges of our net investment in our foreign operations and investments.

At inception of the hedge relationship, a derivative instrument that hedges the exposure to changes in the fair value of a firm commitment or a recognized asset or liability is designated as a fair value hedge. A derivative instrument that hedges a forecasted transaction or the variability of cash flows related to a recognized asset or liability is designated as a cash flow hedge.

Changes in the fair value of derivatives that are designated as fair value hedges are offset against changes in the fair value of the underlying hedged assets, liabilities or firm commitments. Gains and losses on derivatives that are designated as cash flow hedges are recorded as a component of Accumulated other comprehensive loss until the underlying hedged transactions are recognized in earnings. The foreign currency transaction gain or loss of our non-derivative financial instruments and the changes in the fair value of derivatives designated as hedges of our net investment in foreign operations and investments are recognized as a component of Accumulated other comprehensive loss along with the associated foreign currency translation adjustment of the foreign operation or investment, with the amortization of excluded components affecting earnings.

On an ongoing basis, we assess whether derivatives used in hedging transactions are "highly effective" in offsetting changes in the fair value or cash flow of hedged items. For our net investment hedges, we use the dollar offset method to measure effectiveness. For all other hedging programs, we use the long-haul method to assess hedge effectiveness using regression analysis for each hedge relationship. The methodology for assessing hedge effectiveness is applied on a consistent basis for each one of our hedging programs (i.e., interest rate, foreign currency ship construction, foreign currency net investment and fuel). For our regression analyses, we use an observation period of up to three years, utilizing market data relevant to the hedge horizon of each hedge relationship. High effectiveness is achieved when a statistically valid relationship reflects a high degree of offset and correlation between the changes in the fair values of the derivative instrument and the hedged item. If it is determined that a derivative is not highly effective as a hedge or hedge accounting is discontinued, any change in fair value of the derivative since the last date at which it was determined to be effective is recognized in earnings.

Cash flows from derivative instruments that are designated as fair value or cash flow hedges are classified in the same category as the cash flows from the underlying hedged items. In the event that hedge accounting is discontinued, cash flows subsequent to the date of discontinuance are classified within investing activities. Cash flows from derivative instruments not designated as hedging instruments are classified as investing activities.

We consider the classification of the underlying hedged item’s cash flows in determining the classification for the designated derivative instrument’s cash flows. We classify derivative instrument cash flows from hedges of benchmark interest rate or hedges of fuel expense as operating activities due to the nature of the hedged item. Likewise, we classify derivative instrument cash flows from hedges of foreign currency risk on our newbuild ship payments as investing activities.

Our exposure to market risk for changes in interest rates primarily relates to our debt obligations including future interest payments. At December 31, 2020 and 2019, approximately 64.5% and 62.1%, respectively, of our debt was effectively fixed. We use interest rate swap agreements to modify our exposure to interest rate movements and to manage our interest expense.

Market risk associated with our fixed rate debt is the potential increase in fair value resulting from a decrease in interest rates. We use interest rate swap agreements that effectively convert a portion of our fixed-rate debt to a floating-rate basis to manage this risk. At December 31, 2020, we maintained interest rate swap agreements on the following fixed-rate debt instruments:

Market risk associated with our long-term floating rate debt is the potential increase in interest expense from an increase in interest rates. We use interest rate swap agreements that effectively convert a portion of our floating-rate debt to a fixed-rate basis to manage this risk. At December 31, 2020, we maintained interest rate swap agreements on the following floating-rate debt instruments:

(2) Interest rate swap agreements hedging the term loan of Odyssey of the Seas include LIBOR zero-floors matching the debt LIBOR zero-floor. The effective dates of the $460.0 million and $191.7 million interest rate swap agreements are October 2020 and October 2022, respectively. The anticipated unsecured term loan for the financing of Odyssey of the Seas was initially expected to be drawn in October 2020. However, due to the impact of COVID-19 to shipyard operations, there is a delay in the ship delivery.

Our primary exposure to foreign currency exchange rate risk relates to our ship construction contracts denominated in Euros, our foreign currency denominated debt and our international business operations. We enter into foreign currency forward contracts to manage portions of the exposure to movements in foreign currency exchange rates. As of December 31, 2020, the aggregate cost of our ships on order, was $14.2 billion, of which we had deposited $684.8 million as of such date. These amounts do not include any ships placed on order that are contingent upon completion of conditions precedent and/or financing, any ships on order by our Partner Brands and any ships on order placed by Silversea Cruises during the reporting lag period. Refer to Note 19. Commitments and Contingencies, for further information on our ships on order. At December 31, 2020 and 2019, approximately 66.3% and 65.9%, respectively, of the aggregate cost of the ships under construction was exposed to fluctuations in the Euro exchange rate. Our foreign currency forward contract agreements are accounted for as cash flow or net investment hedges depending on the designation of the related hedge.

On a regular basis, we enter into foreign currency forward contracts and, from time to time, we utilize cross-currency swap agreements and collar options to minimize the volatility resulting from the remeasurement of net monetary assets and liabilities denominated in a currency other than our functional currency or the functional currencies of our foreign subsidiaries. During the year ended December 31, 2020, we maintained an average of approximately $364.0 million of these foreign currency forward contracts. These instruments are not designated as hedging instruments. For the years ended December 31, 2020, 2019 and 2018, changes in the fair value of the foreign currency forward contracts resulted in gains (losses) of $(19.0) million, $1.4 million and $(62.4) million, respectively, which offset gains (losses) arising from the remeasurement of monetary assets and liabilities denominated in foreign currencies in those same years of $(1.5) million, $0.4 million and $57.6 million, respectively. These amounts were recognized in earnings within Other income (expense) in our consolidated statements of comprehensive income (loss).

We consider our investments in our foreign operations to be denominated in relatively stable currencies and of a long-term nature. As of December 31, 2020, we maintained foreign currency forward contracts and designated them as hedges of a portion of our net investments primarily in TUI Cruises of €245.0 million, or approximately $299.7 million based on the exchange rate at December 31, 2020. These forward currency contracts mature in October 2021.

We also address the exposure of our investments in foreign operations by denominating a portion of our debt in our subsidiaries' and investments' functional currencies and designating it as a hedge of these subsidiaries and investments. We had designated debt as a hedge of our net investments primarily in TUI Cruises of €215.0 million, or approximately $263.0 million, as of December 31, 2020. As of December 31, 2019, we had designated debt as a hedge of our net investments primarily in TUI Cruises of €319.0 million, or approximately $358.1 million.

Our fuel swap agreements are generally accounted for as cash flow hedges. In the case that our hedged forecasted fuel consumption is not probable of occurring, hedge accounting will be discontinued and the related accumulated other comprehensive gain or loss will be reclassified to Other income (expense) immediately. For hedged forecasted fuel consumption that remains possible of occurring, hedge accounting will be discontinued and the related accumulated other comprehensive gain or loss will

The current suspension of our cruise operations due to the COVID-19 pandemic and our 2020 and expected 2021 ship disposals resulted in reductions to our forecasted fuel purchases. As of December 31, 2020, we discontinued cash flow hedge accounting on 0.6 million metric tons of our fuel swap agreements maturing in 2020 and 2021, which resulted in the reclassification of a net $104.4 million loss from Accumulated other comprehensive loss to Other expense during the year ended December 31, 2020. Changes in the fair value of fuel swaps for which cash flow hedge accounting was discontinued are currently recognized in Other expense each reporting period.

Future suspension of our operations or modifications to our itineraries may affect our expected forecasted fuel purchases which could result in further discontinuance of fuel swap cash flow hedge accounting and the reclassification of deferred gains or losses from Accumulated other comprehensive loss into earnings. Refer to Risk Factors in Part 1, Item 1A. for further discussion on risks related to the COVID-19 pandemic.

At December 31, 2020 there was $13.1 million of estimated unrealized net loss associated with our cash flow hedges pertaining to fuel swap agreements to be reclassified to earnings from Accumulated other comprehensive loss within the next twelve months when compared to none at December 31, 2019. Reclassification is expected to occur as the result of fuel consumption associated with our hedged forecasted fuel purchases.

Our current interest rate derivative instruments require us to post collateral if our Standard & Poor’s and Moody’s credit ratings fall below specified levels. Specifically, under most of our agreements, if on the fifth anniversary of executing a derivative instrument, or on any succeeding fifth-year anniversary, our credit ratings for our senior unsecured debt is rated below BBB- by Standard & Poor’s and Baa3 by Moody’s, then the counterparty will periodically have the right to demand that we post collateral in an amount equal to the difference between (i) the net market value of all derivative transactions with such counterparty that have reached their fifth year anniversary, to the extent negative, and (ii) the applicable minimum call amount.

The amount of collateral required to be posted will change as, and to the extent, our net liability position increases or decreases by more than the applicable minimum call amount. If our credit rating for our senior unsecured debt is subsequently equal to or above BBB- by Standard & Poor’s or Baa3 by Moody’s, then any collateral posted at such time will be released to us and we will no longer be required to post collateral unless we meet the collateral trigger requirement, generally, at the next fifth-year anniversary.

As of December 31, 2020, our senior unsecured debt credit rating was B+ by Standard & Poor's and B2 by Moody's. As of December 31, 2020, seven of our interest rate derivative hedges had a term of at least five years requiring us to post collateral of $57.3 million to satisfy our obligations under our interest rate derivative agreements, taking into account collateral waivers issued by certain banks. On February 25, 2021, Standard & Poor's further downgraded our senior unsecured debt credit rating from B+ to B. We believe the maximum additional collateral we may need to provide under these agreements in the next twelve months is approximately $33.3 million.
