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 were recorded. 

The Company accrues reserves for estimated cancellation fees related to component orders that have been cancelled or are expected to be 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 and recorded.

Warranty Costs 

The Company provides for the estimated cost for hardware and software 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. For products accounted for under subscription accounting pursuant to SOP No. 97-2, the Company recognizes warranty expense as incurred. 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. 

The Company periodically provides updates to its applications and operating system software to maintain the software’s compliance with specifications. The estimated cost to develop such updates is accounted for as warranty cost that is recognized at the time related software revenue is recognized. Factors considered in determining appropriate accruals related to such updates include the number of units delivered, the number of updates expected to occur, and the historical cost and estimated future cost of the resources necessary to develop these updates. 

Stock-Based Compensation 

The Company accounts for stock-based compensation in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 123 (revised 2004), Share-Based Payment . Under the provisions of SFAS No. 123R, stock-based compensation cost is estimated at the grant date based on the award’s fair-value as calculated by the Black-Scholes-Merton (“BSM”) option-pricing model and is recognized as expense ratably on a straight-line basis over the requisite service period. The BSM option-pricing model requires various judgmental assumptions including expected volatility, forfeiture rates, and expected option life. Significant changes in any of these assumptions
