of anticipated transactions may fluctuate over time and may ultimately vary from actual transactions. When anticipated transaction estimates or actual transaction amounts decrease below hedged levels, or when the timing of transactions changes significantly, we are required to reclassify at least a portion of the cumulative changes in fair values of the related hedge contracts from other comprehensive income to other (income) expense, net during the quarter in which such changes occur. Once an anticipated transaction estimate or actual transaction amount decreases below hedged levels, we make adjustments to the related hedge contract in order to reduce the amount of the hedge contract to that of the revised anticipated transaction.

Stock-based Compensation

As of the first quarter of fiscal 2007, we account for stock-based compensation in accordance with FAS 123R. Under the provisions of FAS 123R, the fair value of stock-based compensation is estimated on the date of grant using the Black-Scholes option pricing model. The Black-Scholes option pricing model requires the input of highly subjective assumptions including volatility. Expected volatility is estimated based on implied volatility in market traded options on our common stock with a term greater than one year, along with other factors. Our decision to use implied volatility was based on the availability of actively traded options on our common stock and our assessment that implied volatility is more representative of future stock price trends than historical volatility. If factors change and we use different assumptions for estimating stock-based compensation expense in future periods, stock-based compensation expense may differ materially in the future from that recorded in the current period.

Taxes

We record valuation allowances against our deferred tax assets, when necessary, in accordance with SFAS No. 109, “Accounting for Income Taxes.” Realization of deferred tax assets (such as net operating loss carryforwards) is dependent on future taxable earnings and is therefore uncertain. At least quarterly, we assess the likelihood that our deferred tax asset balance will be recovered from future taxable income. To the extent we believe that recovery is not likely, we establish a valuation allowance against our deferred tax asset, increasing our income tax expense in the period such determination is made.

In addition, we have not recorded U.S. income tax expense for foreign earnings that we have determined to be indefinitely reinvested offshore, thus reducing our overall income tax expense. The amount of earnings designated as indefinitely reinvested offshore is based upon the actual deployment of such earnings in our offshore assets and our expectations of the future cash needs of our U.S. and foreign entities. Income tax considerations are also a factor in determining the amount of foreign earnings to be indefinitely reinvested offshore.

We carefully review all factors that drive the ultimate disposition of foreign earnings determined to be reinvested offshore, and apply stringent standards to overcoming the presumption of repatriation. Despite this approach, because the
