Basis of Presentation	(1) Basis of Presentation During November 2015, the board of directors of Liberty Interactive Corporation ("Liberty Interactive") authorized management to pursue a plan to distribute to holders of its Liberty Ventures common stock shares of a newly formed entity, Liberty Expedia Holdings, Inc. ("Expedia Holdings" or the "Company" as discussed below) ("Expedia Holdings Split-Off"). Following the Expedia Holdings Split-Off, Expedia Holdings is comprised of, among other things, Liberty Interactive's former ownership interest in Expedia, Inc. ("Expedia"), as well as Liberty Interactive's former wholly-owned subsidiary Bodybuilding.com, LLC. As of December 31, 2016, Expedia Holdings beneficially owned approximately 15.7% of the outstanding Expedia common stock which represents a 52.3% voting interest in Expedia. Bodybuilding.com, LLC became a wholly owned subsidiary of Liberty Interactive in October 2015 when Liberty Interactive purchased the remaining ownership interest in Bodybuilding.com, LLC. In 2016, Bodybuilding.com, LLC underwent a corporate restructuring, which resulted in Bodybuilding.com, LLC becoming a wholly-owned subsidiary of Vitalize, LLC (“Vitalize”). The Expedia Holdings Split-Off was accomplished by the redemption by Liberty Interactive on a per share basis of (i) 0.4 of each outstanding share of Liberty Interactive’s Series A Liberty Ventures common stock as of 5:00 p.m., New York City time, on November 4, 2016 (such date and time, the “Redemption Date”) for 0.4 of a share of Expedia Holdings’ Series A common stock, and (ii) 0.4 of each outstanding share of Liberty Interactive’s Series B Liberty Ventures common stock as of the Redemption Date for 0.4 of a share of Expedia Holdings’ Series B common stock, with cash paid in lieu of any fractional shares of Liberty Interactive’s Series A and Series B Liberty Ventures common stock and Expedia Holdings’ Series A and Series B common stock. Following the Expedia Holdings Split-Off, Expedia Holdings and Liberty Interactive operate as separate, publicly traded companies. The Expedia Holdings Split-Off is intended to be tax-free to Liberty Interactive and stockholders of Liberty Ventures. The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States ("GAAP") and represent a consolidation of the historical financial information of Vitalize and Expedia, an equity method affiliate until the date of the Expedia Holdings Split-Off. Although the combination of Vitalize and Expedia were reported as a combined company until the date of the Expedia Holdings Split-Off, these financial statements present all periods as consolidated. These financial statements refer to the combination of the aforementioned subsidiaries as "Expedia Holdings," "the Company," "us," "we" and "our" in the notes to the consolidated financial statements. The Expedia Holdings Split-Off is accounted for at historical cost due to the pro rata nature of the distribution to holders of Liberty Ventures common stock. All significant intercompany accounts and transactions have been eliminated in the consolidated financial statements. Expedia Holdings did not control the decision making process or business management practices of Expedia prior to the Expedia Holdings Split-Off. Accordingly, the Company historically relied on management of this affiliate to provide it with accurate financial information prepared in accordance with GAAP that the Company used in the application of the equity method. In addition, Expedia Holdings relies on audit reports that are provided by the affiliate's independent auditors on the financial statements of such affiliate. The Company is not aware, however, of any errors in or possible misstatements of the financial information provided by its equity affiliate that would have a material effect on Expedia Holding's consolidated financial statements. Description of Business Expedia is an online travel company, empowering business and leisure travelers through technology with the tools and information they need to efficiently research, plan, book and experience travel. Expedia also provides various media and advertising offerings to travel and non-travel advertisers. Expedia operates a strong brand portfolio with global reach, targeting a broad range of travelers, travel suppliers and advertisers. Expedia seeks to grow its business through a dynamic portfolio of travel brands, including its majority owned subsidiaries that feature a broad supply portfolio. Travel suppliers distribute and market products via Expedia’s traditional desktop and mobile offerings, as well as through alternative distribution channels including social media, its private label business and its call centers in order to reach its extensive, global audience. In addition, Expedia’s advertising and media businesses help other businesses, primarily travel providers, reach a large audience of travelers around the globe. Upon completion of the Expedia Holdings Split-Off, the Company’s interest in Expedia is accounted for as a consolidated subsidiary. Prior to the Expedia Holdings Split-Off, Expedia was accounted for as an investment using the equity method, as more fully described in note 3. In 2016, Bodybuilding.com, LLC underwent a corporate restructuring, which resulted in Bodybuilding.com, LLC becoming a wholly-owned subsidiary of Vitalize. Effective November 17, 2016, Bodybuilding.com, LLC amended its Certificate of Formation in the State of Delaware to change its name to Vitalize, LLC, and a new Bodybuilding.com, LLC (“Bodybuilding”) was formed in the state of Delaware, effective November 1, 2016. In addition to the new Bodybuilding, which will continue to offer online retail sales of dietary supplements, Vitalize also formed Verity Nutrition, LLC (“Verity Nutrition”) on August 23, 2016 and WeMotivate, LLC (“WeMotivate”) on October 19, 2016, both of which are also wholly-owned subsidiaries of Vitalize. The financial results for Vitalize are all attributable to Bodybuilding, its wholly-owned subsidiary, for the years ended December 31, 2016, 2015 and 2014. Vitalize is primarily an Internet retailer of sports, fitness, dietary supplements and other health and wellness products. It is also a large publisher of online health and fitness content, offering complimentary fitness content, workout programs, video trainers, articles, recipes, health advice and motivational stories. The online model also includes a combination of detailed product information and real-time user reviews to help its visitors achieve their health and fitness goals. Vitalize's customers include gym-goers, recreational athletes, bodybuilders and any individual seeking to improve their level of health and fitness. Vitalize strives to provide everything necessary to get fit, as well as a platform for users to share their inspirational story once they get there. Seasonality Expedia generally experiences seasonal fluctuations in the demand for its travel products and services. For example, traditional leisure travel bookings are generally the highest in the first three quarters as travelers plan and book their spring, summer and winter holiday travel. The number of bookings typically decreases in the fourth quarter. Because revenue for most of Expedia’s travel products, including merchant and agency hotel, is recognized when the travel takes place rather than when it is booked, revenue typically lags bookings by several weeks or longer. The seasonal revenue impact is exacerbated with respect to income by the nature of Expedia's variable cost of revenue and direct sales and marketing costs, which it typically realizes in closer alignment to booking volumes, and the more stable nature of its fixed costs. Furthermore, operating profits for Expedia's primary advertising business, trivago N.V. (“trivago”), are experienced in the second half of the year, as selling and marketing costs offset revenue in the first half of the year as Expedia aggressively markets during the busy booking period for spring, summer and winter holiday travel. Additionally, trivago has historically earned a substantial portion of its operating profits in the fourth quarter. As a result on a consolidated basis, revenue and income are typically the lowest in the first quarter and highest in the third quarter. The continued growth of Expedia's international operations, advertising business or a change in its product mix, including the assimilation and growth of HomeAway, may influence the typical trend of the seasonality in the future. Expedia expects that as HomeAway continues its shift to more of a transaction-based business model for vacation rental listings, its seasonal trends will generally trend similar to Expedia’s other traditional leisure businesses over time. Split-Off of Expedia Holdings from Liberty Interactive Corporation Following the Expedia Holdings Split-Off, Liberty Interactive and Expedia Holdings operate as separate, publicly traded companies, and neither has any stock ownership, beneficial or otherwise, in the other. In connection with the Expedia Holdings Split-Off, Expedia Holdings entered into certain agreements with Liberty Interactive and/or Liberty Media Corporation (“Liberty Media”) and certain of their subsidiaries in order to govern certain of the ongoing relationships between these companies after the Expedia Holdings Split-Off and to provide for an orderly transition. These agreements include a reorganization agreement, a services agreement, a facilities sharing agreement and a tax sharing agreement. The reorganization agreement between Liberty Interactive and Expedia Holdings provides for, among other things, the principal corporate transactions (including the internal restructuring) required to effect the Expedia Holdings Split-Off, certain conditions to the Expedia Holdings Split-Off and provisions governing the relationship between Expedia Holdings and Liberty Interactive with respect to and resulting from the Expedia Holdings Split-Off. The tax sharing agreement between Liberty Interactive and Expedia Holdings provides for the allocation and indemnification of tax liabilities and benefits between Liberty Interactive and Expedia Holdings and other agreements related to tax matters. Pursuant to the services agreement, Liberty Media provides Expedia Holdings with general and administrative services including legal, tax, accounting, treasury and investor relations support. Under the facilities sharing agreement among Liberty Media, a subsidiary of Liberty Media and Expedia Holdings, Expedia Holdings will share office space with Liberty Interactive and Liberty Media and related amenities at Liberty Media's corporate headquarters. Expedia Holdings will reimburse Liberty Media for direct, out-of-pocket expenses incurred by Liberty Media in providing these services and for costs that will be negotiated semi-annually. Under these various agreements, less than $1 million was reimbursable to Liberty for the year ended December 31, 2016.
