NOTE 15SEGMENT INFORMATION As of September 30, 2018 , we operated through three reportable business segments: triple-net leased properties, senior living operations and office operations. In our triple-net leased properties segment, we invest in and own seniors housing and healthcare properties throughout the United States and the United Kingdom and lease those properties to healthcare operating companies under triple-net or absolute-net leases that obligate the tenants to pay all property-related expenses. In our senior living operations segment, we invest in seniors housing communities throughout the United States and Canada and engage independent operators, such as Atria and Sunrise, to manage those communities. In our office operations segment, we primarily acquire, own, develop, lease and manage MOBs and life science and innovation centers throughout the United States. Information provided for all other includes income from loans and investments and other miscellaneous income and various corporate-level expenses not directly attributable to any of our three reportable business segments. Assets included in all other consist primarily of corporate assets, including cash, restricted cash, loans receivable and investments, and miscellaneous accounts receivable. Our chief operating decision makers evaluate performance of the combined properties in each reportable business segment and determine how to allocate resources to those segments, in significant part, based on segment NOI and related measures. We define segment NOI as total revenues, less interest and other income, property-level operating expenses and office building services costs . We consider segment NOI useful because it allows investors, analysts and our management to measure unlevered property-level operating results and to compare our operating results to the operating results of other real estate companies between periods on a consistent basis. In order to facilitate a clear understanding of our historical consolidated operating results, segment NOI should be examined in conjunction with income from continuing operations as presented in our Consolidated Financial Statements and other financial data included elsewhere in this Quarterly Report on Form 10-Q. Interest expense, depreciation and amortization, general, administrative and professional fees, income tax expense and other non-property specific revenues and expenses are not allocated to individual reportable business segments for purposes of assessing segment performance. There are no intersegment sales or transfers. Summary information by reportable business segment is as follows: For the Three Months Ended September 30, 2018 Triple-Net Leased Properties Senior Living Operations Office Operations All Other Total
