NOTE 2    UNEARNED REVENUE

Unearned revenue is comprised of the following items:

Volume licensing programs   –   Represents customer billings for multi-year licensing arrangements, paid either upfront or annually at the beginning of each billing coverage period, which are accounted for as subscriptions with revenue recognized ratably over the billing coverage period.

Undelivered elements   –   Represents free post-delivery telephone support and the right to receive unspecified upgrades/enhancements of Microsoft Internet Explorer on a when-and-if-available basis. The amount recorded as unearned is based on the sales price of those elements when sold separately and is recognized ratably on a straight-line basis over the related product’s life cycle. The percentage of revenue recorded as unearned due to undelivered elements ranges from approximately 15% to 25% of the sales price for Windows XP Home, approximately 5% to 15% of the sales price for Windows XP Professional, and approximately 1% to 15% of the sales price for desktop applications, depending on the terms and conditions of the license and prices of the elements. Product life cycles are currently estimated at three and one-half years for Windows operating systems and two years for desktop applications.

Other   –   Represents payments for post-delivery support and consulting services to be performed in the future, online advertising for which the advertisement has yet to be displayed, Microsoft Business Solutions maintenance and enhancement billings, Xbox Live and other billings that are accounted for as subscriptions, and other agreements where Microsoft is committed to the delivery of future enhancements, products, or services, including the TV platform.
