7. SEGMENT DATA

We measure segment performance based on operating income (loss). Excluding discontinued operations our broadcast segment includes stations in 49 markets located predominately in the eastern, mid-western and southern United States. The operating results of WLAJ-TV and WLWC-TV, which were sold effective January 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 six months ended June 30, 2013 and 2012. Our other operating divisions consist of sign design and fabrication; regional security alarm operating and bulk acquisitions 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. Our Other Operating Divisions and Corporate are not reportable segments but are included for reconciliation purposes. We had approximately $171.5 million and $171.0 million of intercompany loans between the broadcast segment, operating divisions and corporate as of June 30, 2013 and 2012, respectively. We had $5.0 million in intercompany interest expense related to intercompany loans between the broadcast segment, other operating divisions and corporate for the both three months ended June 30, 2013, and 2012, respectively. For the six months ended June 30, 2013 and 2012, we had $10.0 million and $9.9 million, respectively, in intercompany interest expense. Intercompany loans and interest expense are excluded from the tables below. All other intercompany transactions are immaterial.
