Industry Segments Data We have two reportable segments, Wireless and Wireline.Our reportable segments are business units that offer different products and are each managed separately. A description of our reportable segments follows: Wireless - We offer wholesale wireless services. Wireline - We provide a full range of wireless, data, video, voice, and managed services to residential customers, businesses, governmental entities, and educational and medical institutions primarily in Alaska. We evaluate performance and allocate resources based on Adjusted EBITDA, which is defined as earnings plus imputed interest on financed devices before:  Net interest expense,  Income taxes,  Depreciation and amortization expense,  Loss on extinguishment of debt,  Software impairment charge,  Share-based compensation expense,  Accretion expense,  Loss attributable to non-controlling interest resulting from NMTC transactions,  Gains and impairment losses on equity and cost method investments,  Gain recorded for adjusting to fair value assets that were included as consideration paid to acquire a fiber system, and  Other non-cash adjustments. Management believes that this measure is useful to investors and other users of our financial information in understanding and evaluating operating performance as an analytical indicator of income generated to service debt and fund capital expenditures.In addition, multiples of current or projected Adjusted EBITDA are used to estimate current or prospective enterprise value. The accounting policies of the reportable segments are the same as those described in Note 1 of this Form 10-K.We have no intersegment sales. We earn all revenues through sales of services and products within the United States. All of our long-lived assets are located within the United States of America, except approximately 82% of our undersea fiber optic cable systems which transit international waters and all of our satellite transponders. Wireless plan fee and usage revenues from external customers are
