REPORTABLE SEGMENTS | REPORTABLE SEGMENTS The Company’s investments in real estate are geographically diversified and management evaluates the operating performance of each at an individual investment level and considers each investment to be an operating segment. The Company has aggregated all of its operating segments into four reportable segments based on the location of the segment and the underlying asset class. Management has aggregated the Company's investments that are not office properties in “other” based on the geographic location of the investment, due to the Company's ownership of interests in various different types of investments that do not stand alone as their own reportable segment. The Company’s reporting segments consist of the following, based on the Company’s investments as of June 30, 2018 : • Domestic office investments ( 9 investments) • Domestic other investments ( 5 investments) • International office investments ( 8 investments) • International other investments ( 11 investments) The tables below provide additional information related to each of the Company’s segments, geographic location and a reconciliation to the Company’s net loss, as applicable. “Corporate-Level Accounts” includes amounts incurred by the corporate-level entities which are not allocated to any of the reportable segments (all amounts other than percentages are in thousands).
