General	General Description of Business We are a global cruise company. As of September 30, 2017, we own and operate three global cruise brands: Royal Caribbean International, Celebrity Cruises and Azamara Club Cruises (collectively, our "Global Brands"). We also own a 50% joint venture interest in the German brand TUI Cruises, a 49% interest in the Spanish brand Pullmantur and have a minority interest in the Chinese brand SkySea Cruises (collectively, our "Partner Brands"). We account for our investments in our Partner Brands under the equity method of accounting. Prior to August 2016, Pullmantur Holdings S.L. ("Pullmantur Holdings"), the parent company of the Pullmantur brand (formerly known as Royal Caribbean Holdings de España S.L.), was wholly owned by us. Effective July 31, 2016, we sold 51% of our interest in Pullmantur Holdings. We retain a 49% interest in Pullmantur Holdings as well as full ownership of the four vessels currently operated by the Pullmantur brand under bareboat charter arrangements. We account for the bareboat charters of the vessels to Pullmantur Holdings as operating leases. We also provide certain ship management services and other related services to Pullmantur Holdings.

Summary of Significant Accounting Policies in this Quarterly Report on Form 10-Q and in our Annual Report on Form 10-K for the year ended December 31, 2016 for a discussion of our significant accounting policies. All significant intercompany accounts and transactions are eliminated in consolidation. We consolidate entities over which we have control, usually evidenced by a direct ownership interest of greater than 50%, and variable interest entities where we are determined to be the primary beneficiary. Refer to Note 5. Other Assets for further information regarding our variable interest entities. For affiliates we do not control but over which we have significant influence on financial and operating policies, usually evidenced by a direct ownership interest from 20% to 50%, the investment is accounted for using the equity method. Prior to January 1, 2016, we consolidated the operating results of Pullmantur Holdings on a two-month reporting lag to allow for more timely preparation of our consolidated financial statements. Effective January 1, 2016, we eliminated the two-month reporting lag to reflect Pullmantur Holding's financial position, results of operations and cash flows concurrently and consistently with the fiscal calendar of the Company (the "elimination of the Pullmantur reporting lag"). The elimination of the Pullmantur reporting lag represented a change in accounting principle which we believed to be preferable because it provided more current information to the users of our financial statements. A change in accounting principle requires retrospective application, if material. The impact of the elimination of the Pullmantur reporting lag was immaterial to prior periods and was immaterial for our fiscal year ended December 31, 2016. As a result, we have accounted for this change in accounting principle in our consolidated results for the first quarter of 2016. Accordingly, the results of Pullmantur Holdings for November and December 2015 are included in our statement of comprehensive income (loss) for the nine months ended September 30, 2016. The effect of this change was a decrease to net income of $21.7 million, which has been reported within Other expense in our consolidated statements of comprehensive income (loss) for the nine months ended September 30, 2016.
