Segment Information

We determine our business segments based upon our management and internal reporting structures, as well as the basis that our chief operating decision maker makes resource allocation decisions. We report our financial performance based on the following segments: Local Media, National Media, Other.

Our Local Media segment includes our local broadcast stations and their related digital operations. It is comprised of seventeen ABC affiliates, five NBC affiliates, two FOX affiliates and two CBS affiliates. We also have two MyTV affiliates, one CW affiliate, two independent stations and four Azteca America Spanish-language affiliates. Our Local Media segment earns revenue primarily from the sale of advertising to local, national and political advertisers and retransmission fees received from cable operators, telecommunications companies and satellite carriers. We also receive retransmission fees from over-the-top virtual MVPDs such as YouTubeTV, DirectTV Now and Sony Vue.

Our National Media segment includes our collection of national brands. Our national brands include Katz, Stitcher and its advertising network Midroll Media (Midroll), Newsy, Triton and other national brands. These operations earn revenue primarily through the sale of advertising.

We allocate a portion of certain corporate costs and expenses, including information technology, certain employee benefits and shared services, to our business segments. The allocations are generally amounts agreed upon by management, which may differ from an arms-length amount.

Our chief operating decision maker evaluates the operating performance of our business segments and makes decisions about the allocation of resources to our business segments using a measure called segment profit. Segment profit excludes interest, defined benefit pension plan expense, income taxes, depreciation and amortization, impairment charges, divested operating units, restructuring activities, investment results and certain other items that are included in net income (loss) determined in accordance with accounting principles generally accepted in the United States of America.
