14. SEGMENT DATA:

We measure segment performance based on operating income (loss). Excluding discontinued operations, our broadcast segment includes stations in 79 markets located throughout the continental United States. The operating results of WLAJ-TV and WLWC-TV, which were sold effective March 1, 2013 and April 1, 2013, respectively, are classified as discontinued operations and are not included in our consolidated results of continuing operations for the years ended 2013 and 2012. Our other operating divisions primarily consist of sign design and fabrication; regional security alarm operating and bulk acquisitions; manufacturing and service of broadcast antennas and transmitters and real estate ventures. 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 $172.3 million and $171.9 million of intercompany loans between the broadcast segment, other operating divisions and corporate as of December 31, 2014 and 2013, respectively. We had $20.7 million, $20.0 million, and $20.0 million in intercompany interest expense related to intercompany loans between the broadcast segment, other operating divisions and corporate for the years ended December 31, 2014, 2013, and 2012, respectively. All other intercompany transactions are immaterial.
