of product shipments. The Company records a write- down for inventories of components and products, including third-party products held for resale, which have become obsolete or are in excess of anticipated demand or net realizable value. The Company performs a detailed review of inventory each fiscal quarter that considers multiple factors including demand forecasts, product life cycle status, product development plans, current sales levels, and component cost trends. The personal computer and consumer electronic industries are subject to a rapid and unpredictable pace of product and component obsolescence and demand changes. If future demand or market conditions for the Company’s products are less favorable than forecasted or if unforeseen technological changes negatively impact the utility of component inventory, the Company may be required to record additional write-downs which would negatively affect gross margins in the period when the write-downs are recorded. 

The Company accrues necessary reserves for cancellation fees related to component orders that have been cancelled. Consistent with industry practice, the Company acquires components through a combination of purchase orders, supplier contracts, and open orders based on projected demand information. These commitments typically cover the Company’s requirements for periods ranging from 30 to 150 days. If there is an abrupt and substantial decline in demand for one or more of the Company’s products or an unanticipated change in technological requirements for any of the Company’s products, the Company may be required to record additional reserves for cancellation fees that would negatively affect gross margins in the period when the cancellation fees are identified. 

Warranty Costs 

The Company provides currently for the estimated cost for product warranties at the time the related revenue is recognized based on historical and projected warranty claim rates, historical and projected cost-per-claim, and knowledge of specific product failures that are outside of the Company’s typical experience. Each quarter, the Company reevaluates its estimates to assess the adequacy of its recorded warranty liabilities considering the size of the installed base of products subject to warranty protection, and adjusts the amounts as necessary. If actual product failure rates or repair costs differ from estimates, revisions to the estimated warranty liability would be required and could negatively affect the Company’s results of operations. 

Income Taxes 

The Company records a tax provision for the anticipated tax consequences of the reported results of operations. In accordance with Statement of Financial Accounting Standards (SFAS) No. 109, Accounting for Income Taxes , the provision for income taxes is computed using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates that
