BASIS OF PRESENTATION	BASIS OF PRESENTATION The consolidated financial statements present the results of operations, financial position, and cash flows of Marriott International, Inc. and its consolidated subsidiaries (referred to in this report as “we,” “us,” “Marriott,” or the “Company”). In order to make this report easier to read, we also refer throughout to (1) our Consolidated Financial Statements as our “Financial Statements,” (2) our Consolidated Statements of Income as our “Income Statements,” (3) our Consolidated Balance Sheets as our “Balance Sheets,” (4) our Consolidated Statements of Cash Flows as our “Statements of Cash Flows,” (5) our properties, brands, or markets in the United States and Canada as “U.S. & Canada,” and (6) our properties, brands, or markets in our Europe, Middle East & Africa, Greater China, Asia Pacific excluding China, and Caribbean & Latin America regions, as “International.” References throughout to numbered “Notes” refer to these Notes to Consolidated Financial Statements, unless otherwise stated. In addition, we use the term “hotel owners” throughout this report to refer, collectively, to owners of hotels and other lodging offerings operating in our system pursuant to franchise agreements, management agreements, license agreements or similar arrangements, and we use the term “hotels in our system” to refer to hotels and other lodging offerings operating in our system pursuant to such arrangements, as well as hotels that we own or lease. The terms “hotel owners” and “hotels in our system” exclude Homes & Villas by Marriott BonvoySM (which we also exclude from our property and room count), timeshare, residential, and The Ritz-Carlton Yacht Collection®. Preparation of financial statements that conform with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements, the reported amounts of revenues and expenses during the reporting periods, and the disclosures of contingent liabilities. Accordingly, ultimate results could differ from those estimates. The accompanying Financial Statements reflect all normal and recurring adjustments necessary to present fairly our financial position at fiscal year-end 2025 and fiscal year-end 2024 and the results of our operations and cash flows for fiscal years 2025, 2024, and 2023. We have eliminated all material intercompany transactions and balances between entities consolidated in these Financial Statements. In addition, in the 2025 fourth quarter, to enhance understanding of the Company’s general and administrative costs, we reclassified amounts attributable to other expenses previously reported under the “General, administrative, and other” caption to the “Owned, leased, and other expense” caption of our Income Statements. The expenses that were reclassified from “General, administrative, and other” are certain costs associated with our property-related fee revenues, such as guarantee expense, provision for credit losses, and certain brand-related or property-related expenses, as well as costs associated with certain third-party agreements. We reclassified prior period amounts, which totaled $129 million in 2024 and $144 million in 2023, to conform to our current presentation.
