Under certain circumstances, however, the Company recognizes revenue upon shipment, prior to acceptance by the customer. The portion of revenue associated with installation is deferred based on relative sales price and recognized upon completion of the installation. Spare parts revenue is recognized when the product has been shipped and risk of loss has passed to the customer, and collectability is reasonably assured. Service and maintenance contract revenue is recognized ratably over the term of the maintenance contract. Revenue from services performed in the absence of a contract, such as consulting and training revenue, is recognized when the related services are performed, and collectability is reasonably assured. The Company's arrangements generally do not include any provisions for cancellation, termination or refunds that would significantly impact recognized revenue. </font></div><div style="line-height:120%;padding-top:12px;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In October 2009, the FASB issued amended revenue recognition guidance for arrangements with multiple deliverables and certain software sold with tangible products. This guidance eliminates the residual method of revenue recognition and allows the use of management's best estimate of selling price for individual elements of an arrangement when vendor-specific objective evidence ("VSOE") or third-party evidence ("TPE") is unavailable.  The Company elected to early adopt this accounting guidance at the beginning of its second quarter of the fiscal year ended June 30, 2010 and applied the adoption retrospectively to the beginning of the fiscal year to apply the guidance to transactions originating or materially modified after June 30, 2009. The implementation resulted in additional qualitative disclosures but did not have a material impact on the Company's financial position, results of operations or cash flows as this guidance does not generally change the units of accounting for the Company's revenue transactions.</font></div><div style="line-height:120%;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"> </font></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company enters into revenue arrangements that may consist of multiple deliverables of its products and services where certain elements of a sales contract are not delivered and accepted in one reporting period. In many instances, products are sold in stand-alone arrangements. Services are sold separately through renewals of annual maintenance contracts. As a result, for substantially all of the arrangements with multiple deliverables pertaining to products and services, the Company uses VSOE or TPE to allocate the selling price to each deliverable. The Company determines TPE based on historical prices charged for products and services when sold on a stand-alone basis.</font></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">When the Company is unable to establish relative selling price using VSOE or TPE, the Company uses estimated selling prices (“ESP”) in its allocation of arrangement consideration. The objective of ESP 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. ESP could potentially be used for new or customized products.</font></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company regularly reviews relative selling prices and maintains internal controls over the establishment and updates of these estimates.</font></div></div>
