Display advertising revenue 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 arrangement and the number of hours worked during the period. Consulting revenue for fixed-price services
arrangements is recognized as services are provided. Revenue from prepaid points redeemable for the purchase of
software or services is recognized upon redemption of the points and delivery of the software or services.
Cost of Revenue
Cost of revenue includes: manufacturing and distribution costs for products sold and programs licensed; operating costs
related to product support service centers and product distribution centers; costs incurred to include software on PCs sold
by OEMs, to drive traffic to our websites, and to acquire online advertising space (“traffic acquisition costs”); costs
incurred to support and maintain Internet-based products and services, including datacenter costs and royalties; warranty
costs; inventory valuation adjustments; costs associated with the delivery of consulting services; and the amortization of
capitalized research and development costs. Capitalized research and development costs are amortized over the
estimated lives of the products.
Product Warranty
We provide for the estimated costs of fulfilling our obligations under hardware and software warranties at the time the
related revenue is recognized. For hardware warranties, we estimate the costs based on historical and projected product
failure rates, historical and projected repair costs, and knowledge of specific product failures (if any). The specific
hardware warranty terms and conditions vary depending upon the product sold and the country in which we do business,
but generally include parts and labor over a period generally ranging from 90 days to three years. For software warranties,
we estimate the costs to provide bug fixes, such as security patches, over the estimated life of the software. We regularly
reevaluate our estimates to assess the adequacy of the recorded warranty liabilities and adjust the amounts as
necessary.
Research and Development
Research and development expenses include payroll, employee benefits, stock-based compensation expense, and other
headcount-related expenses associated with product development. Research and development expenses also include
third-party development and programming costs, localization costs incurred to translate software for international markets,
and the amortization of purchased software code and services content. Such costs related to software development are
included in research and development expense until the point that technological feasibility is reached, which for our
software products, is generally shortly before the products are released to manufacturing. Once technological feasibility is
reached, such costs are capitalized and amortized to cost of revenue over the estimated lives of the products.
Sales and Marketing
Sales and marketing expenses include payroll, employee benefits, stock-based compensation expense, and other
headcount-related expenses associated with sales and marketing personnel, and the costs of advertising, promotions,
trade shows, seminars, and other programs. Advertising costs are expensed as incurred. Advertising expense was $2.3
billion, $2.6 billion, and $1.6 billion in fiscal years 2014, 2013, and 2012, respectively.
Stock-Based Compensation
We measure stock-based compensation cost at the grant date based on the fair value of the award and recognize it as
expense, net of estimated forfeitures, over the vesting or service period, as applicable, of the stock award (generally four
to five years) using the straight-line method.
Employee Stock Purchase Plan
Shares of our common stock may be purchased by employees at three-month intervals at 90% of the fair market value of
the stock on the last day of each three-month period. Compensation expense for the employee stock purchase plan is
measured as the discount the employee is entitled to upon purchase and is recognized in the period of purchase.
