in Income Taxes, issued in July 2006. FIN 48 applies to all tax positions related to income taxes subject to SFAS No. 109. Under FIN 48 we recognize the benefit from a tax position only if it is more-likely-than-not that the position would be sustained upon audit based solely on the technical merits of the tax position. The cumulative effect of adoption of FIN 48 did not result in a material adjustment to our tax liability for unrecognized income tax benefits. Our policy to include interest and penalties related to unrecognized tax benefits as a component of income tax expense did not change as a result of implementing the FIN 48. Please refer to Note 13 of these Notes to Consolidated Financial Statements for additional information. 

Goodwill

 

Our impairment review process compares the fair value of the reporting unit in which the goodwill resides to its carrying value.  We determined that our reporting units are equivalent to our operating segments for the purposes of completing our Statement of Financial Accounting Standards No. 142, or SFAS No. 142, Goodwill and Other Intangible Assets, impairment test.  We utilize a two-step approach to testing goodwill for impairment. The first step tests for possible impairment by applying a fair value-based test. In computing fair value of our reporting units, we use estimates of future revenues, costs and cash flows from such units. The second step, if necessary, measures the amount of such impairment by applying fair value-based tests to individual assets and liabilities. We elected to perform our annual goodwill impairment review during the fourth quarter of each fiscal year. We completed our most recent annual impairment test during the fourth quarter of fiscal year 2008 and concluded that there was no impairment.  Determining the number of reporting units and the fair value of a reporting unit requires us to make judgments 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.  In addition, we make judgments and assumptions in allocating assets and liabilities to each of our reporting units.  The long-term financial forecast represents the best estimate that we have at this time and we believe that its underlying assumptions are reasonable. However, actual performance in the near-term and longer-term could be materially different from these forecasts, which could impact future estimates of fair value of our reporting units and may result in a charge to earnings in future periods due to the potential for a write-down of goodwill in connection with such tests.



Stock-based Compensation

 

    Effective January 30, 2006, we adopted the provisions of SFAS No. 123(R), which establishes accounting for stock-based awards exchanged for employee services. Accordingly, stock-based compensation cost is measured at
