	$	25,246,595	$	25,466,808

(1)Amount includes accumulated depreciation and amortization for assets in service.

Ships under construction include progress payments for the construction of new ships as well as planning, design, capitalized interest and other associated costs. We capitalized interest costs of $59.1 million, $56.5 million and $49.6 million for the years ended December 31, 2020, 2019 and 2018, respectively.

During 2020, we took delivery of Celebrity Apex, Silver Origin and Silver Moon. Refer to Note 9. Debt for further information on the financings for Celebrity Apex and Silver Moon. The October 2020 Silversea Cruises delivery and related financing for the Silver Moon was reported in our consolidated financial statements as of and for the year ended December 31, 2020, regardless of the three month reporting lag for Silversea Cruises, due to the materiality of the transaction.

During the first quarter 2020, we determined that the lease for Silver Explorer, operated by Silversea Cruises and previously classified as a finance lease, was an operating lease based on modification of the terms of the lease. Accordingly, Silver Explorer is included within Operating lease right-of use assets, Current portion of operating lease liabilities, and Long term lease liabilities in our consolidated balance sheets. Refer to Note 10. Leases for further information.

During 2019, we took delivery of Spectrum of the Seas and Celebrity Flora. Refer to Note 9. Debt for further information. During 2019 Silversea Cruises terminated the operating lease for Silver Discover.

Long-lived Assets impairments

We review our long-lived assets for impairment whenever events or circumstances indicate potential impairment losses exist. The impact of COVID-19 on our expected future operating cash flows, as well as decisions to dispose of certain vessels, resulted in the identification of impairment triggers for certain vessels. Refer to Note 1. General for further information regarding COVID-19 and its impact to the Company.

We estimated the recoverability of certain vessels using undiscounted cash flow analyses at interim dates throughout 2020 and again at December 31,2020. A number of vessels were found to have net carrying values in excess of their estimated undiscounted future cash flows and, as such, were subject to fair value assessments. Fair value was determined based on our intended use of the identified vessels and, as such, we used a combination of discounted cash flows, replacement cost, scrap and residual value techniques to estimate fair value. Differences between the estimated fair values and the net carrying values were recorded as an impairment charge within the period the loss was identified. Consequently, we recorded $635.5 million of impairment losses during the year ended 2020. Included in this amount are $171.3 million impairment losses recorded for the three ships that we chartered to Pullmantur Holdings, prior to its filing for reorganization. Refer to Note 8. Other Assets for further information regarding Pullmantur's reorganization. During the quarter ended September 30, 2020, we sold the ships previously chartered to Pullmantur Holdings to third parties for amounts approximating their carrying values and no further impairment was recorded. Also included in the $635.5 million impairment loss for the year ended December 31, 2020, is a $166.8 million impairment charge for the three Azamara ships to be included in the sale of the Azamara brand that is expected to close in the first quarter of 2021.

The suspension of operations, as discussed in Note 1. General, and the possibility of further suspensions create uncertainty in forecasting undiscounted cash flows, which are used to determine if a vessel is at risk of impairment and in estimating the fair value of our ships. Our principal assumptions used in our undiscounted cash flows consisted of:

•The timing of our return to service, changes in market conditions and port or other restrictions;

•Forecasted net revenues, primarily the timing of returning to normalized operations, and occupancy rates; and

•Intended use of the vessel for the remaining useful life.

The adverse impact COVID-19 will continue to have on our business, operating results, cash flows and overall financial condition is uncertain and may result in changes to the assumptions used in the impairment tests discussed above, which may result in additional impairments to these assets in the future.

During the year ended December 31, 2020, we also determined that certain construction in progress projects would be reduced in scope or would no longer be completed as a result of our capital cost containment measures in response to the COVID-19 impact on our liquidity. This led to an impairment charge of $91.5 million of construction in progress assets.

These impairment charges were reported within Impairment and Credit Losses in our consolidated statements of comprehensive (loss) income.
