Information About the Company's Operating Segments The Company, through its interests in subsidiaries and other companies, is primarily engaged in the broadband communications services industry. The Company identifies its reportable segments as (A) those consolidated companies that represent 10% or more of its consolidated annual revenue, annual Adjusted OIBDA (as defined below) or total assets and (B) those equity method affiliates whose share of earnings represent 10% or more of the Companys annual pre-tax earnings. The Company evaluates performance and makes decisions about allocating resources to its operating segments based on financial measures such as revenue, Adjusted OIBDA (as defined below), and subscriber metrics. For the three and nine months ended September 30, 2019 , the Company has identified the following subsidiary as a reportable segment:  GCI Holdings-provides a full range of wireless, data, video, voice, and managed services to residential, businesses, governmental entities, and educational and medical institutions primarily in Alaska. For presentation purposes the Company is providing financial information for Liberty Broadband. While the Companys equity method investment in Liberty Broadband does not meet the reportable segment threshold defined above, the Company believes that the inclusion of such information is relevant to users of these financial statements.  Liberty Broadband-an equity method affiliate of the Company, accounted for at fair value, has a non-controlling interest in Charter, and a wholly-owned subsidiary, Skyhook Wireless, Inc. ("Skyhook"). Charter is the second largest cable operator in the United States and a leading broadband communications services company providing video, Internet and voice services. Skyhook provides a Wi-Fi based location platform focused on providing positioning technology and contextual location intelligence solutions. The Companys operating segments are strategic business units that offer different products and services. They are managed separately because each segment requires different technologies, distribution channels and marketing strategies. The accounting policies of the consolidated subsidiaries included in the segments are the same as those described in the Companys Summary of Significant Accounting Policies in note 2 to the accompanying consolidated financial statements to the Annual Report on Form 10-K for the year ended December 31, 2018. Performance Measures Revenue by segment from contracts with customers, classified by customer type and significant service offerings follows: Three months ended Nine months ended September 30, September 30, 2019 2018 2019 2018 amounts in thousands GCI Holdings Consumer Revenue Wireless $ 29,509 25,584 84,506 62,312 Data 42,920 39,652 125,555 88,921 Video 21,194 22,272 63,255 50,180 Voice 4,051 4,368 12,833 10,246 Business Revenue Wireless 20,060 18,071 57,837 44,889 Data 69,960 59,585 201,803 154,239 Video 4,115 4,927 11,928 9,436 Voice 6,747 6,361 19,587 14,282 Lease, grant, and revenue from subsidies 22,472 24,226 67,914 55,114 Total GCI Holdings 221,028 205,046 645,218 489,619 Corporate and other 6,016 5,100 17,128 15,221 Total $ 227,044 210,146 662,346 504,840 Liberty Broadband revenue totaled $3.7 million and $3.5 million for the three months ended September 30, 2019 and 2018, respectively and $10.9 million and $18.7 million for the nine months ended September 30, 2019 and 2018, respectively. The Company had gross receivables of $216 million and deferred revenue of $38 million at September 30, 2019 from contracts with customers, which amounts exclude receivables and deferred revenue arising from leases, grants, and subsidies. Our customers generally pay for services in advance of the performance obligation and therefore these prepayments are recorded as deferred revenue. The deferred revenue is recognized as revenue in the accompanying condensed consolidated statements of operations as the services are provided. Changes in the contract liability balance for the Company during the nine months ended September 30, 2019 were not materially impacted by other factors. The Company expects to recognize revenue in the future related to performance obligations that are unsatisfied (or partially unsatisfied) of approximately $63 million in the remainder of 2019, $233 million in 2020, $164 million in 2021, $112 million in 2022 and $97 million in 2023 and thereafter. The Company applies certain practical expedients as permitted under ASC 606 and does not disclose information about remaining performance obligations that have original expected durations of one year or less, information about revenue remaining from usage based performance obligations that are recognized over time as-invoiced, or variable consideration allocated to wholly unsatisfied performance obligations. For segment reporting purposes, the Company defines Adjusted OIBDA as revenue less cost of sales, operating expenses, and selling, general and administrative expenses (excluding stock-based compensation). The Company believes this measure is an important indicator of the operational strength and performance of its businesses by identifying those items that are not directly a reflection of each business' performance or indicative of ongoing business trends. In addition, this measure allows management to view operating results and perform analytical comparisons and benchmarking between businesses and identify strategies to improve performance. This measure of performance excludes depreciation and amortization, stock-based compensation, separately reported litigation settlements, insurance proceeds and restructuring and impairment charges that are included in the measurement of operating income pursuant to GAAP. Accordingly, Adjusted OIBDA should be considered in addition to, but not as a substitute for, operating income, net income, cash flow provided by operating activities and other measures of financial performance prepared in accordance with GAAP. Adjusted OIBDA is summarized as follows: Three months ended September 30, Nine months ended September 30, 2019 2018 2019 2018 amounts in thousands GCI Holdings $ 71,960 57,945 182,552 156,608 Liberty Broadband (4,586 ) (2,198 ) (11,877 ) (414 ) Corporate and other (5,382 ) (7,205 ) (17,199 ) (20,256 ) 61,992 48,542 153,476 135,938 Eliminate Liberty Broadband 4,586 2,198 11,877 414 $ 66,578 50,740 165,353 136,352 Other Information September 30, 2019 Total Investments Capital assets in affiliates expenditures amounts in thousands GCI Holdings $ 3,346,168 580 107,431 Liberty Broadband 12,172,047 12,067,329 75 Corporate and other 7,299,135 168,259 1,202 Eliminate Liberty Broadband (12,172,047 ) (12,067,329 ) (75 ) Consolidated $ 10,645,303 168,839 108,633 The following table provides a reconciliation of Adjusted OIBDA to operating income (loss) and earnings (loss) from continuing operations before income taxes: Three months ended September 30, Nine months ended September 30, 2019 2018 2019 2018 amounts in thousands Adjusted OIBDA $ 66,578 50,740 165,353 136,352 Stock-based compensation (5,768 ) (7,761 ) (18,153 ) (20,926 ) Depreciation and amortization (66,466 ) (62,848 ) (200,035 ) (143,257 ) Insurance proceeds and restructuring, net 1,482  (236 )  Operating income (loss) (4,174 ) (19,869 ) (53,071 ) (27,831 ) Interest expense (38,353 ) (37,614 ) (116,357 ) (81,304 ) Share of earnings (loss) of affiliates, net 1,921 10,856 (2,443 ) 18,714 Realized and unrealized gains (losses) on financial instruments, net 156,165 495,509 1,844,863 (4,328 ) Tax Sharing Agreement 2,362 2,492 18,895 (25,456 ) Other, net (540 ) (834 ) 13,824 (982 ) Earnings (loss) from continuing operations before income taxes $ 117,381 450,540 1,705,711 (121,187 )
