("SHS"), and our Park Holidays subsidiaries and the other entities through which we operate our business in the United Kingdom ("UK") are referred to herein as the "Company," "SUI," "us," "we," or "our." We have elected to be taxed as a real estate investment trust ("REIT") pursuant to Section 856(c) of the Internal Revenue Code of 1986, as amended ("Code"). We analyzed the various REIT tests and confirmed that we continued to qualify as a REIT during the three and six months ended June 30, 2026. We follow accounting standards set by the Financial Accounting Standards Board ("FASB"). FASB establishes accounting principles generally accepted in the United States of America ("GAAP"), which we follow to ensure that we consistently report our financial condition, results of operations, and cash flows. References to GAAP issued by the FASB in these footnotes are to the FASB Accounting Standards Codification ("ASC"). These unaudited Condensed Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") for interim financial information and in accordance with GAAP. We present interim disclosures and certain information and footnote disclosures as required by SEC rules and regulations. Accordingly, the unaudited Condensed Consolidated Financial Statements do not include all of the information and footnotes required by GAAP for complete financial statements. The accompanying unaudited Condensed Consolidated Financial Statements reflect, in the opinion of management, all adjustments, including adjustments of a normal and recurring nature, necessary for a fair presentation of the interim financial statements. All significant intercompany transactions have been eliminated in consolidation. The results of operations for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2025 as filed with the SEC on February 25, 2026 (our "2025 Annual Report").
