retrospective application to prior periods’ financial statements, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. Statement 154 is effective for accounting changes made in fiscal years beginning after December 15, 2005; however, the Statement does not change the transition provisions of any existing accounting pronouncements. We do not believe adoption of Statement 154 will have a material effect on our consolidated financial position, results of operations or cash flows.

 

Accounting for Uncertainty in Income Taxes:   On July 13, 2006, the FASB issued Interpretation No. 48, Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109 . Interpretation 48 clarifies the accounting for uncertainty in income taxes recognized in an entity’s financial statements in accordance with Statement 109 and prescribes a recognition threshold and measurement attribute for financial statement disclosure of tax positions taken or expected to be taken on a tax return. Additionally, Interpretation 48 provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. Interpretation 48 is effective for fiscal years beginning after December 15, 2006, with early adoption permitted. We are currently evaluating whether the adoption of Interpretation 48 will have a material effect on our consolidated financial position, results of operations or cash flows.



Up until May 31, 2006, we measured compensation expense for our stock-based incentive programs using the intrinsic value method prescribed by Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees . Under this method, we did not record compensation expense when stock options were granted to eligible participants as long as the exercise price was not less than the fair market value of the stock when the option was granted. In accordance with FASB Statement No. 123, Accounting for Stock-Based Compensation , and FASB Statement No. 148, Accounting for Stock-Based Compensation—Transition and Disclosure , we disclosed our pro forma net income or loss and net income or loss per share as if the fair value-based method had been applied in measuring compensation expense for our stock-based incentive programs.

 

We were required to adopt the provisions of FASB Statement 123(R), Share-Based Payment , in the first quarter of fiscal 2007. Although the adoption of Statement 123(R)’s fair value method has no adverse impact on our balance sheet or total cash flows, it affects our operating expenses, net income and earnings per share. The actual effects of adopting Statement 123(R) will depend on numerous factors including the amounts of share-based payments granted in the future, the valuation model we use to value future share-based payments to employees and estimated forfeiture rates. We estimate that stock-based compensation expense will reduce diluted earnings per share by $0.02 to $0.03 in fiscal 2007.
