Activision, Inc. — 2004 Annual Report Notes to Consolidated Financial Statements Commencing upon the related product’s release, capitalized intellectual property license costs are amortized to cost of sales—intellectual property licenses based on the ratio of current revenues for the specific product to total projected revenues for all products in which the licensed property will be utilized. As intellectual property license contracts may extend for multiple years, the amortization of capitalized intellectual property license costs relating to such contracts may extend beyond one year. For intellectual property included in products that have been released, we evaluate the future recoverability of capitalized amounts on a quarterly basis. The primary evaluation criterion is actual title performance. Significant management judgments and estimates are utilized in the assessment of the recoverability of capitalized costs. In evaluating the recoverability of capitalized costs, the assessment of expected product performance utilizes forecasted sales amounts and estimates of additional development costs to be incurred. If revised forecasted or actual product sales are less than and/or revised forecasted or actual costs are greater than the original forecasted amounts utilized  in the initial recoverability analysis, the actual impairment charge may be larger than originally estimated in any  given quarter. Additionally, as noted above, as many of our intellectual property licenses extend for multiple products over multiple years, we also assess the recoverability of capitalized intellectual property license costs based on certain qualitative factors such as the success of other products and/or entertainment vehicles utilizing the intellectual property, whether there are any future planned theatrical releases or television series based on the intellectual property and the rights holder’s continued promotion and exploitation of the intellectual property. Material differences may result in the amount and timing of charges for any period if management makes different judgments or utilizes different estimates in evaluating these qualitative factors. Inventories are valued at the lower of cost (first-in, first-out) or market. Property and equipment are recorded at cost. Depreciation and amortization are provided using the straight-line method over the shorter of the estimated useful lives or the lease term: buildings, 25 to 33 years; computer equipment, office furniture and other equipment, 2 to 5 years; leasehold improvements, through the life of the lease. When assets are retired or disposed of, the cost and accumulated depreciation thereon are removed and any resultant gains or losses are recognized in current operations. We account for goodwill using the provisions of SFAS No. 142, “Goodwill and Other Intangibles.” SFAS No. 142 addresses financial accounting and reporting requirements for acquired goodwill and other intangible assets. Under SFAS No. 142, goodwill is deemed to have an indefinite useful life and should not be amortized but rather tested at least annually for impairment. An impairment loss should be recognized if the carrying amount of goodwill is not recov- erable and its carrying amount exceeds its fair value. In accordance with SFAS No. 142, we have not amortized goodwill during the years ended March 31, 2004, 2003 and 2002. We recognize revenue from the sale of our products upon the transfer of title and risk of loss to our customers. Revenue from product sales is recognized after deducting the estimated allowance for returns and price protection. With respect to license agreements that provide customers the right to make multiple copies in exchange for guaranteed amounts, revenue is recognized upon delivery of such copies. Per copy royalties on sales that exceed the guarantee are recog- nized as earned. In addition, in order to recognize revenue for both product sales and licensing transactions, persuasive evidence of an arrangement must exist and collection of the related receivable must be probable. Revenue recognition also determines the timing of certain expenses, including cost of sales—intellectual property licenses and cost of sales— software royalties and amortization.
