guidance for the initial implementation of SFAS No. 123(R). SFAS No. 123(R) allows for either prospective recognition of compensation expense or retrospective recognition. We intend to adopt SFAS No. 123(R) using the modified prospective method, which requires the application of the accounting standard as of January 30, 2006, the first day of our fiscal 2007. Expensing these incentives in future periods will materially and adversely affect our reported operating results as the stock-based compensation expense would be charged directly against our reported earnings. We anticipate that our stock-based compensation expense will be approximately $18 to $22 million for the first quarter of fiscal 2007 and we are unsure how the market will react to this adverse affect on our operating results, which could impact our stock price.



During the first quarter of fiscal 2006, we transitioned from a Black-Scholes model to a binomial model for calculating the estimated fair value of new stock-based compensation awards granted under our stock option plans. As a result of recent regulatory guidance, including SAB No. 107, and in anticipation of the impending effective date of SFAS No. 123(R), we reevaluated the assumptions we use to estimate the value of employee stock options and shares issued under our employee stock purchase plan, beginning with stock options granted and shares issued under our employee stock purchase plan in our first quarter of fiscal 2006. We determined that the use of implied volatility is expected to be more reflective of market conditions and, therefore, can reasonably be expected to be a better indicator of expected volatility than historical volatility. Additionally, in the first quarter of fiscal 2006, we began segregating options into groups for employees with relatively homogeneous exercise behavior in order to make full use of the capabilities of the binomial valuation model. As such, the expected term is based on detailed historical data about employees' exercise behavior, vesting schedules, and death and disability probabilities. We believe the resulting binomial calculation provides a more refined estimate of the fair value of our employee stock options. For our employee stock purchase plan, we decided to continue to use the Black-Scholes model to calculate the estimated fair value.



In June 2005, the FASB issued SFAS No. 154, or SFAS No. 154, Accounting Changes and Error Corrections, a replacement of APB Opinion No. 20 and FASB Statement No. 3. SFAS No. 154 applies to all voluntary changes in accounting principle, and changes the requirements for accounting for and reporting of a change in accounting principle. We will adopt SFAS 154 during the first quarter of fiscal 2007. We do not expect the adoption of SFAS No. 154 to have a material impact on our consolidated financial position, results of operations or cash flows.



In June 2005, the FASB ratified the Emerging Issues Task Force’s, or EITF’s, Issue No. 05-06, or EITF No. 05-06, Determining the Amortization Period for Leasehold Improvements. EITF No. 05-06 provides that the amortization period used for leasehold improvements acquired in a business combination or
