Business Segments We are a hospitality company with operations organized in two distinct operating segments: (i) management and franchise and (ii) ownership. These segments are managed and reported separately because of their distinct economic characteristics. The management and franchise segment includes all of the hotels we manage for third-party owners, as well as all franchised hotels operated or managed by someone other than us. As of December 31, 2018 , this segment included 689 managed hotels and 4,874 franchised hotels consisting of 882,873 total rooms. This segment also earns licensing fees from HGV and co-brand credit card arrangements, as well as fees for managing properties in our ownership segment. As of December 31, 2018 , the ownership segment included 71 properties totaling 21,720 rooms, comprising 62 hotels that we wholly owned or leased, one hotel owned by a consolidated non-wholly owned entity, two hotels leased by consolidated VIEs and six hotels owned or leased by unconsolidated affiliates. The performance of our operating segments is evaluated primarily on operating income, without allocating other revenues and expenses or general and administrative expenses.
