Our cash, cash equivalents and restricted cash are invested in high quality financial instruments with banks and financial institutions. Such deposits may be in excess of insured limits provided on such deposits. </font></div><div style="line-height:120%;padding-top:8px;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Our accounts receivable are unsecured and represent amounts due to us based on contractual obligations of our customers. We mitigate credit risk in respect to accounts receivable by performing ongoing credit evaluations of our customers to assess the probability of accounts receivable collection based on a number of factors, including past transaction experience with the customer, evaluation of their credit history, the credit limits extended and review of the invoicing terms of the arrangement. In situations where a customer may be thinly capitalized and we have limited payment history with it, we will either establish a small credit limit or require it to prepay its purchases. We generally do not require our customers to provide collateral to support accounts receivable. We have recorded an allowance for doubtful accounts for those receivables that we have determined not to be collectible. We mitigate credit risk in respect to the notes receivable by performing ongoing credit evaluations of the borrower to assess the probability of collecting all amounts due to us under the existing contractual terms. </font></div><div style="line-height:120%;padding-top:8px;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We market and sell our products through both our direct sales force and our channel partners, including distributors, value-added resellers, system integrators and original equipment manufacturer (“OEM”) partners and in conjunction with various technology partners. Significant customers are those which represent more than </font><font style="font-family:inherit;font-size:10pt;">10%</font><font style="font-family:inherit;font-size:10pt;"> of our total net revenue during the period or net accounts receivable balance at each respective balance sheet date.</font></div></div>

We use judgment and estimates when determining warranty costs based on historical costs to replace product returns within the warranty period at the time we recognize revenue. We accrue for potential warranty claims at the time of shipment as a component of cost of revenues based on historical experience and other relevant information. We reserve for specifically identified products if and when we determine we have a systemic product failure. Although we engage in extensive product quality programs, if actual product failure rates or use of materials differ from estimates, additional warranty costs may be incurred, which could reduce our gross margin. The accrued warranty liability is recorded in accrued liabilities in the accompanying consolidated balance sheets. </font></div></div>

Products and PCS generally qualify as separate units of accounting. Our hardware deliverables include EOS software, which together deliver the essential functionality of our products. For multiple element arrangements, we allocate revenue to each unit of accounting based on the relative selling price. The relative selling price for each element is based upon the following hierarchy: vendor-specific objective evidence (“VSOE”), if available; third-party evidence (“TPE”), if VSOE is not available; and best estimate of selling price (“BESP”), if neither VSOE nor TPE is available. As we have not been able to establish VSOE or TPE for our products and most of our services, we generally utilize BESP for the purposes of allocating revenue to each unit of accounting. </font></div><table cellpadding="0" cellspacing="0" style="padding-top:8px;font-family:Times New Roman; font-size:10pt;"><tr><td style="width:65px;" rowspan="1" colspan="1"></td><td rowspan="1" colspan="1"></td></tr><tr><td style="vertical-align:top" rowspan="1" colspan="1"><div style="line-height:120%;font-size:10pt;padding-left:32px;"><font style="font-family:inherit;font-size:10pt;">•</font></div></td><td style="vertical-align:top;" rowspan="1" colspan="1"><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">VSOE</font><font style="font-family:inherit;font-size:10pt;">—We determine VSOE based on our historical pricing and discounting practices for the specific products and services when sold separately.

TPE is determined based on competitor prices for interchangeable products or services when sold separately to similarly situated customers. However, as our products contain a significant element of proprietary technology and offer substantially different features and functionality, the comparable pricing of products with similar functionality typically cannot be obtained. Additionally, as we are unable to reliably determine what competitors products’ selling prices are on a stand-alone basis, we are not able to obtain reliable evidence of TPE of selling price. </font></div></td></tr></table><table cellpadding="0" cellspacing="0" style="padding-top:8px;font-family:Times New Roman; font-size:10pt;"><tr><td style="width:65px;" rowspan="1" colspan="1"></td><td rowspan="1" colspan="1"></td></tr><tr><td style="vertical-align:top" rowspan="1" colspan="1"><div style="line-height:120%;font-size:10pt;padding-left:32px;"><font style="font-family:inherit;font-size:10pt;">•</font></div></td><td style="vertical-align:top;" rowspan="1" colspan="1"><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">BESP</font><font style="font-family:inherit;font-size:10pt;">—When we are unable to establish selling price using VSOE or TPE, we use BESP in our allocation of arrangement consideration. The objective of BESP is to determine the price at which we would transact a sale if the product or service was sold regularly on a stand-alone basis. BESP is based on considering multiple factors including, but not limited to the sales channel (reseller, distributor or end customer), the geographies in which our products and services were sold (domestic or international) and size of the end customer. </font></div></td></tr></table><div style="line-height:120%;padding-top:8px;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We limit the amount of revenue recognition for delivered elements to the amount that is not contingent on the future delivery of products or services, future performance obligations, or subject to customer-specific return, acceptance or refund privileges. </font></div><div style="line-height:120%;padding-top:8px;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We account for multiple agreements with a single partner as </font><font style="font-family:inherit;font-size:10pt;">one</font><font style="font-family:inherit;font-size:10pt;"> arrangement if the contractual terms and/or substance of those agreements indicate that they may be so closely related that they are, in effect, parts of a single arrangement. </font></div><div style="line-height:120%;padding-top:8px;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We may occasionally accept returns to address customer satisfaction issues even though there is no contractual provision for such returns. We estimate returns for sales to customers based on historical returns rates applied against current-period gross revenues. Specific customer returns and allowances are considered when determining our sales return reserve estimate.</font></div></div>

Those estimates and assumptions include, but are not limited to, revenue recognition and deferred revenue; allowance for doubtful accounts and sales return reserve; determination of fair value for stock-based awards; accounting for income taxes, including the valuation allowance on deferred tax assets and reserves for uncertain tax positions; valuation of inventory; valuation of warranty accruals; and the recognition and measurement of contingent liabilities. We evaluate our estimates and assumptions on an ongoing basis using historical experience and other factors and adjust those estimates and assumptions when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ from these estimates, and those differences could be material to the consolidated financial statements.</font></div></div>
