Allowance for Doubtful Accounts
The allowance for doubtful accounts receivable is based on an analysis of our historical charge-off ratio, our aging of accounts receivable and our assessment of the collectability of our receivables. If there is a deterioration of one of our major customer's credit worthiness or actual account defaults are higher than our historical trends, our reserve estimates could be adversely impacted.
We provide for inventory obsolescence based upon assumptions about future demand, market conditions and anticipated timing of the release of next generation products. If actual market conditions or future demand are less favorable than those projected, or if next generation products are released earlier than anticipated, additional inventory write-downs may be required.
also review, on a quarterly basis, the value of inventory on hand for which a newer and more advanced technology or product is currently, or will soon be, available. When we believe that we will not be able to sell the products in inventory at or above cost, we mark the inventory down to market value. 28 -------------------------------------------------------------------------------- Table of Contents Income Taxes As part of the process of preparing our consolidated financial statements, we are required to estimate income taxes in each of the jurisdictions in which we operate. The provision for income taxes is determined using the asset and liability approach for accounting for income taxes. A current liability is recognized for the estimated taxes payable for the current year. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the enacted tax rates in effect for the year in which the timing differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of changes in tax rates or tax laws are recognized in the provision for income taxes in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amount more-likely-than-not to be realized. To the extent we establish or change the valuation allowance in a period, the tax effect will generally flow through the statement of operations. In the case of an acquired or merged entity, we will record any valuation allowance on a deferred tax asset established through purchase accounting procedures as an adjustment to goodwill at the acquisition date. Any subsequent change to a valuation allowance established during purchase accounting that occurs within the measurement period of the acquisition (a period not to exceed twelve months) will also be recorded as an adjustment to goodwill, provided that such a change relates to new information about the facts and circumstances that existed on the acquisition date. All other changes to a valuation allowance established during purchase accounting will flow through the statement of operations. The determination of our provision for income taxes requires significant judgment, the use of estimates and the interpretation and application of complex tax laws. We are subject to income taxes in the U.S. and numerous foreign jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes and recording the related tax assets and liabilities. In the ordinary course of our business, there are transactions and calculations for which the ultimate tax determination is uncertain. In spite of our belief that we have appropriate support for all the positions taken on our tax returns, we acknowledge that certain positions may be successfully challenged by the taxing authorities. Therefore, an accrual for uncertain tax positions is provided for, when necessary. In the event that we have accruals for uncertain tax positions, these accruals are reviewed quarterly and reversed upon being sustained under audit, the expiration of the statute of limitations, new information, or other determination by the taxing authorities. The provision for income taxes includes the impact of changes in uncertain tax positions. Although we believe our recorded tax assets and liabilities are reasonable, tax laws and regulations are subject to interpretation and inherent uncertainty; therefore our assessments can involve both a series of complex judgments about future events and rely on estimates and assumptions. Although we believe these estimates and assumptions are reasonable, the final determination could be materially different than that which is reflected in our provision for income taxes and recorded tax assets and liabilities.
