Goodwill

 

We review goodwill for impairment annually and whenever events or changes in circumstances indicate its carrying value may not be recoverable in accordance with FASB Statement No. 142, Goodwill and Other Intangible Assets . The provisions of Statement 142 require that a two-step impairment test be performed on goodwill. In the first step, we compare the fair value of each reporting unit to its carrying value. Our reporting units are consistent with the reportable segments identified in Note 15 of the Notes to Consolidated Financial Statements. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, goodwill is considered not impaired and we are not required to perform further testing. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, then we must perform the second step of the impairment test in order to determine the implied fair value of the reporting unit’s goodwill. If the carrying value of a reporting unit’s goodwill exceeds its implied fair value, then we would record an impairment loss equal to the difference.

Determining the fair value of a reporting unit is judgmental in nature and involves the use of significant estimates and assumptions. These estimates and assumptions include revenue growth rates and operating margins used to calculate projected future cash flows, risk-adjusted discount rates, future economic and market conditions and determination of appropriate market comparables. We base our fair value estimates on assumptions we believe to be reasonable but that are unpredictable and inherently uncertain. Actual future results may differ from those estimates. In addition, we make certain judgments and assumptions in allocating shared assets and liabilities to determine the carrying values for each of our reporting units. Our most recent annual goodwill impairment analysis, which was performed during the fourth quarter of fiscal 2006, did not result in an impairment charge.

 

Revenue Recognition

 

We derive revenues from the following sources: (1) software, which includes new software license and software license updates and product support revenues, and (2) services, which include consulting, On Demand and education revenues.

 

New software license revenues represent fees earned from granting customers licenses to use our database, middleware and applications software, and exclude revenues derived from software license updates, which are included in software license updates and product support. While the basis for software license revenue recognition is substantially governed by the provisions of Statement of Position No. 97-2, Software Revenue Recognition , issued by the American Institute of Certified Public Accountants, we exercise judgment and use estimates in connection with the determination of the amount of software and services revenues to be recognized in each accounting period.

 

For software license arrangements that do not require significant modification or customization of the underlying software, we recognize new software license
