Organization and Basis of Presentation | NOTE 1 — Organization and Basis of Presentation Description of Business Expedia, Inc. and its subsidiaries provide travel products and services to leisure and corporate travelers in the United States and abroad as well as various media and advertising offerings to travel and non-travel advertisers. These travel products and services are offered through a diversified portfolio of brands including: Expedia.com®, Hotels.com®, Hotwire.com TM, Travelocity®, Expedia® Affiliate Network, Classic Vacations®, Expedia Local Expert®, Expedia® CruiseShipCenters®, CarRentals.com TM, Wotif Group, Orbitz®, CheapTickets®, ebookers®, SilverRail Technologies, Inc., Egencia®, trivago®, HomeAway® and eLong TM through its sale on May 22, 2015. In addition, many of these brands have related international points of sale, including those as part of AirAsia-Expedia. We refer to Expedia, Inc. and its subsidiaries collectively as “Expedia,” the “Company,” “us,” “we” and “our” in these consolidated financial statements. Basis of Presentation The accompanying consolidated financial statements include Expedia, Inc., our wholly-owned subsidiaries, and entities we control, or in which we have a variable interest and are the primary beneficiary of expected cash profits or losses. We record our investments in entities that we do not control, but over which we have the ability to exercise significant influence, using the equity method. We have eliminated significant intercompany transactions and accounts. We believe that the assumptions underlying our consolidated financial statements are reasonable. However, these consolidated financial statements do not present our future financial position, the results of our future operations and cash flows. Seasonality We generally experience seasonal fluctuations in the demand for our 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 our 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 for our hotel business and can be several months for our vacation rental business. Historically, HomeAway has seen seasonally stronger bookings in the first quarter of the year, with the relevant stays occurring during the peak summer travel months. The seasonal revenue impact is exacerbated with respect to income by the nature of our variable cost of revenue and direct sales and marketing costs, which we typically realize in closer alignment to booking volumes, and the more stable nature of our fixed costs. Furthermore, operating profits for our primary advertising business, trivago, have typically been experienced in the second half of the year, particularly the fourth quarter, as selling and marketing costs offset revenue in the first half of the year as we aggressively market during the busy booking period for spring, summer and winter holiday travel. 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 our international operations, advertising business or a change in our product mix, including the growth of HomeAway, may influence the typical trend of the seasonality in the future, and there may also be business or market driven dynamics that result in short-term impacts to revenue or profitability that differ from the typical seasonal trends.
