browser technologies updates and technical support, the fair value of which is recognized over the product’s estimated life cycle. Changes to the elements in a software arrangement, the ability to identify VSOE for those elements, the fair value of the respective elements, and changes to a product’s estimated life cycle could materially impact the amount of earned and unearned revenue. Judgment is also required to assess whether future releases of certain software represent new products or upgrades and enhancements to existing products. 

SFAS 115, Accounting for Certain Investments in Debt and Equity Securities, and Securities and Exchange Commission (SEC) Staff Accounting Bulletin (SAB) 59, Accounting for Noncurrent Marketable Equity Securities, provide guidance on determining when an investment is other-than-temporarily impaired, which also requires judgment. In making this judgment, Microsoft evaluates, among other factors, the duration and extent to which the fair value of an investment is less than its cost; the financial health of and business outlook for the investee, including factors such as industry and sector performance, changes in technology, and operational and financing cash flow; and the Company’s intent and ability to hold the investment. 

Microsoft accounts for research and development costs in accordance with several accounting pronouncements, including SFAS 2, Accounting for Research and Development Costs, and SFAS 86, Accounting for the Costs of Computer Software to be Sold, Leased, or Other-wise Marketed. SFAS 86 specifies that costs incurred internally in creating a computer software product should be charged to expense when incurred as research and development until technological feasibility has been established for the product. Once technological feasibility is established, all software costs should be capitalized until the product is available for general release to customers. Judgment is required in determining when the technological feasibility of a product is established. Microsoft has determined that technological feasibility for its products is reached shortly before the products are released to manufacturing. Costs incurred after technological feasibility is established are not material, and accordingly, the Company expenses all research and development costs when incurred. 

Microsoft is subject to various legal proceedings and claims, the outcomes of which are subject to significant uncertainty. SFAS 5, Accounting for Contingencies, requires that an estimated loss from a loss contingency should be accrued by a charge to income if it is probable that an asset has been impaired or a liability has been incurred and the amount of the loss can be reasonably estimated. Disclosure of a contingency is required if there is at least a reasonable possibility that a loss has been incurred. The Company evaluates, among other factors, the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss. Changes in these factors could materially impact the Company’s financial position or its results of operations.
