Revenue recognition

Revenue is recognized when persuasive evidence of arrangements exists, delivery has occurred, the fee is fixed or determinable, and collectability is probable. Revenue for retail packaged products, products licensed to original equipment manufacturers (OEMs) generally is recognized as products are shipped or made available. Certain multi-yr licensing arrangements include a perpetual license for current products combined with rights to receive future versions of DW products on a when-and-if-available basis and are accounted for as subscriptions, with billings recorded as unearned revenue ratably over the billing period. Revenue related to our Xbox 360 gaming console, Kinect for Xbox 360, games published by us, and other hardware components is generally recognized when ownership is transferred to the resellers. Revenue related to games published by 3^rd parties for use on the Xbox 360 platform is recognized as advertisements are displayed. Search advertising revenue is recognized when the ad appears in the search results or when the action necessary to earn the revenue has been completed. Consulting services revenue is recognized as services are rendered, generally based on the negotiated hourly rate in the consulting agreement and the number of hours worked during the period.
