SEGMENT DATA

We measure segment performance based on operating income (loss). Our broadcast segment includes stations in 79 markets located throughout the continental United States. Our other operating divisions primarily consist of sign design and fabrication; regional security alarm operating and bulk acquisitions; manufacturing and service of broadcast antennas; service of broadcast transmitters; real estate ventures; and other private equity investments. All of our other operating divisions are located within the United States. Corporate costs primarily include our costs to operate as a public company and to operate our corporate headquarters location. Other Operating Divisions and Corporate are not reportable segments but are included for reconciliation purposes. We had approximately $226.0 million and $172.3 million of intercompany loans between the broadcast segment, other operating divisions and corporate as of September 30, 2015 and 2014, respectively. We had $6.1 million and $5.3 million in intercompany interest expense related to intercompany loans between the broadcast segment, other operating divisions and corporate for the three months ended September 30, 2015 and 2014, respectively. We had $16.9 million and $15.3 million in intercompany interest expense for the nine months ended September 30, 2015 and 2014, respectively. All other intercompany transactions are immaterial.
