Use of Key Business Metrics A paid listing is defined by HomeAway as a fee to list a property advertisement on one or more websites in its marketplace. A paid listing allows a property owner or manager to include a description of the property, along with location, pricing, availability, a specified number of photos and contact information. Most listings are sold on a subscription basis, and some listing packages may include listings on more than one of HomeAway's websites. When purchased at the same time in one bundle, HomeAway counts this as one paid listing. Listings are also sold on a pay-for-performance basis to property managers. Average revenue per listing is computed by HomeAway as listing revenue for the period divided by the average of paid listings at the beginning and end of the period and then annualizing the result. The price of listings varies by website and can include various additional fees associated with listing enhancements. The average revenue per listing may fluctuate based on the timing and nature of acquisitions, impacting the number of average paid listings for a given period; changes in HomeAway's base pricing; uptake of listing enhancements; changes in the pricing of enhancements; changes in brand and listing type mix; and the impact of foreign exchange rates on HomeAway's listing revenue outside of the United States. The renewal rate for HomeAway's subscription listings at the end of any period is defined as the percentage of those paid listings that were active at the end of the period ended twelve months prior that are still active as of the end of the reported period. HomeAway includes most brands in its calculation of renewal rate. Subscriptions to BedandBreakfast.com and Toprural.es remain excluded until HomeAway can further develop its database system.
