Accounting for Stock-Based Compensation. We elected to adopt the modified retrospective application method provided by SFAS 123(R) and accordingly, financial statement amounts for the periods presented herein reflect results as if the fair value method of expensing had been applied from the original effective date of SFAS 123.
Stock-based compensation represents the cost related to stock-based awards granted to employees. We measure stock-based compensation cost at grant date, based on the estimated fair value of the award, and recognize the cost as expense on a straight-line basis (net of estimated forfeitures) over the employee requisite service period. We estimate the fair value of stock options using a Black-Scholes valuation model. The expense is recorded in Costs; Selling, General and Administrative; and Research and Development in the Consolidated Statements of Income based on the employees respective functions.
We record deferred tax assets for awards that result in deductions on our income tax returns, based on the amount of compensation cost recognized and our statutory tax rate in the jurisdiction in which we will receive a deduction. Differences between the deferred tax assets recognized for financial reporting purposes and the actual tax deduction reported in our income tax return are recorded in Capital in Excess of Par Value (if the tax deduction exceeds the deferred tax asset).
