Segment Reporting [Abstract]

Segment Reporting

Segment Reporting

We manage our business on a consolidated basis and therefore have one reportable segment: real estate asset management. The chief operating decision maker, or CODM, is our President and Chief Executive Officer. The CODM assesses performance, allocates resources and makes strategic decisions based on net income attributable to the RMR Group Inc. and consolidated revenue and expense information as shown in our consolidated statements of comprehensive income. The CODM is also regularly provided with information on revenue related to our management agreements with the Managed Equity REITs, SEVN and other clients, which are detailed in Note 10, Related Person Transactions. The CODM is not regularly provided with detailed expense information. The accounting policies of our reportable segment are the same as those described in Note 2, Summary of Significant Accounting Policies. The measure of segment assets is reported as total assets in our consolidated balance sheets.
