RMR Australia holds an Australian financial services license granted by the Australian Securities & Investments Commission. In these financial statements, we refer to the Managed REITs, the Managed Operators, RIF, AIC and ABP Trust as our Client Companies. For periods prior to June 5, 2015, Members’ profit sharing was determined based on federal income tax concepts, including our historical cash method of accounting for tax purposes. The condensed consolidated statements of comprehensive income do not reflect an accrual for Members profit sharing, as the determination of any profit sharing payments were made annually in the fourth quarter of our fiscal year after an assessment of our tax basis earnings. Any profit sharing payments were discretionary in nature and determined solely by our Founders after the assessment of tax basis earnings and the capital requirements of the business. The accompanying condensed consolidated financial statements of RMR Inc. are unaudited. Certain information and disclosures required by U.S. generally accepted accounting principles, or GAAP, for complete financial statements have been condensed or omitted. We believe the disclosures made are adequate to make the information presented not misleading. However, the accompanying condensed consolidated financial statements should be read in conjunction with the financial statements and notes contained in our Annual Report. In the opinion of management, all adjustments, which include only normal recurring adjustments considered necessary for a fair presentation, have been included. All intercompany transactions and balances with or among our consolidated subsidiaries have been eliminated. Our operating results for interim periods are not necessarily indicative of the results that may be expected for the full year. Preparation of these financial statements in conformity with GAAP, requires our management to make certain estimates and assumptions that may affect the amounts reported in these financial statements and related notes. The actual results could differ from these estimates.
