The Company recognizes product revenue upon shipment of product under contractual terms, which transfer title to customers upon shipment, under normal credit terms, net of estimated sales returns and allowances at the time of shipment. Revenue is deferred if there are significant post-delivery obligations or if the fees are not fixed or determinable. When significant post-delivery obligations exist, revenue is deferred until such obligations are fulfilled. The Company’s arrangements generally do not have any significant post-delivery obligations. If the Company’s arrangements include customer acceptance provisions, revenue is recognized upon obtaining the signed acceptance certificate from the customer, unless the Company can objectively demonstrate that the delivered products or services meet all the acceptance criteria specified in the arrangement prior to obtaining the signed acceptance. In those instances where revenue is recognized prior to obtaining the signed acceptance certificate, the Company uses successful completion of customer testing as the basis to objectively demonstrate that the delivered products or services meet all the acceptance criteria specified in the arrangement. The Company also considers historical acceptance experience with the customer, as well as the payment terms specified in the arrangement, when revenue is recognized prior to obtaining the signed acceptance certificate. When collectability is not reasonably assured, revenue is recognized when cash is collected.</font></div><div style="line-height:120%;padding-top:12px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company makes certain sales to product distributors. These customers are given certain privileges to return a portion of inventory. Return privileges generally allow distributors to return inventory based on a percent of purchases made within a specific period of time. The Company recognizes revenue on sales to distributors that have contractual return rights when the products have been sold by the distributors, unless there is sufficient customer specific sales and sales returns history to support revenue recognition upon shipment. In those instances when revenue is recognized upon shipment to distributors, the Company uses historical rates of return from the distributors to provide for estimated product returns.</font></div><div style="line-height:120%;padding-top:12px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company derives revenue primarily from stand-alone sales of its products. In certain cases, the Company’s products are sold along with services, which include education, training, installation, and/or extended warranty services. As such, some of the Company’s sales have multiple deliverables. The Company’s products and services qualify as separate units of accounting and are deemed to be non-contingent deliverables as the Company’s arrangements typically do not have any significant performance, cancellation, termination and refund type provisions. Products are typically considered delivered upon shipment. Revenue from services is recognized ratably over the period during which the services are to be performed.</font></div><div style="line-height:120%;padding-top:12px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">For multiple deliverable revenue arrangements, the Company allocates revenue to products and services using the relative selling price method to recognize revenue when the revenue recognition criteria for each deliverable are met. The selling price of a deliverable is based on a hierarchy and if the Company is unable to establish vendor-specific objective evidence of selling price (“VSOE”) it uses third-party evidence of selling price (“TPE”), and if no such data is available, it uses a best estimated selling price (“BESP”). In most instances, particularly as it relates to products, the Company is not able to establish VSOE for all deliverables in an arrangement with multiple elements. This may be due to infrequently selling each element separately, not pricing products within a narrow range, or only having a limited sales history. When VSOE cannot be established, the Company attempts to establish the selling price of each element based on TPE. Generally, the Company’s marketing strategy differs from that of the Company’s peers and the Company’s offerings contain a significant level of customization and differentiation such that the comparable pricing of products with similar functionality cannot be obtained. Furthermore, the Company is unable to reliably determine what similar competitor products’ selling prices are on a stand-alone basis. Therefore, the Company is typically not able to determine TPE for the Company’s products.</font></div><div style="line-height:120%;padding-top:12px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">When the Company is unable to establish selling price using VSOE or TPE, the Company uses BESP. The objective of BESP is to determine the price at which the Company would transact a sale if the product or service were sold on a stand-alone basis. The BESP of each deliverable is determined using average discounts from list price from historical sales transactions or cost plus margin approaches based on factors, including but not limited to, the Company’s gross margin objectives, pricing practices and customer and market specific considerations.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Training, education and installation service arrangements are typically not material, are short term in nature and are largely completed shortly after delivery of the product.</font></div><div style="line-height:120%;padding-top:12px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Extended warranty services are priced based on the type of product and are sold in </font><font style="font-family:inherit;font-size:10pt;">one</font><font style="font-family:inherit;font-size:10pt;"> to </font><font style="font-family:inherit;font-size:10pt;">five</font><font style="font-family:inherit;font-size:10pt;"> year durations. Extended warranty services include the right to warranty coverage beyond the standard warranty period. In substantially all of the arrangements with multiple deliverables pertaining to arrangements with these services, the Company has used and intends to continue using VSOE to determine the selling price for the services. The Company determines VSOE based on its normal pricing practices for these specific services when sold separately.</font></div></div>
