Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis Of Presentation

Basis of Presentation

The accompanying condensed consolidated financial statements include our accounts and the accounts of our subsidiaries. All intercompany accounts and transactions have been eliminated.

Our interim financial statements have been prepared in accordance with generally accepted accounting principles in the United States ("U.S. GAAP") for interim financial information and the rules and regulations of the Securities and Exchange Commission ("SEC") for interim financial statements and accounting policies, consistent, in all material respects with those applied in preparing our audited consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013, filed with the SEC on February 28, 2014, as amended. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In our opinion, all adjustments, consisting of only normal recurring adjustments considered necessary for fair presentation, have been included.

Our fiscal periods end on the Saturday closest to month-end, except that our fiscal year ends on December 31. All references to the quarter or three month period refer to our fiscal quarter. Our fiscal quarters covered by this report ended on March 29, 2014 and March 30, 2013.

Operating results for the three month period ended March 29, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014, or any future periods.

USE OF ESTIMATES

The preparation of the financial statements and related disclosures in conformity with U.S. GAAP require us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and the related disclosure of contingent assets and liabilities at the date of the consolidated financial statements. By their nature, these estimates and judgments are subject to an inherent degree of uncertainty. On an ongoing basis, management evaluates its estimates, including those related to inventories, purchase order commitments, warranty obligations, asset retirement obligations, bad debts, estimated useful lives of fixed assets and intangible assets, asset impairment, intangible asset impairment, income taxes, deferred income tax valuation allowance, stock-based compensation, and contingencies and litigation. We base our estimates on historical experience and on various other analyses and assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

In June 2013, the Financial Accounting Standards Board ("FASB") issued guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists, with the purpose of reducing diversity in practice. This new standard requires the netting of unrecognized tax benefits against a deferred tax asset for a loss or other carryforward that would apply in settlement of the uncertain tax positions. The new guidance was effective for us beginning January 1, 2014. We adopted the guidance during the first quarter of 2014 and there was no material impact on our condensed consolidated financial statements.

Revenue Recognition

We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the arrangement consideration is fixed or determinable, and collectability is reasonably assured. We derive revenue from four sources: system sales, spare parts sales, service contracts and license fees.

Provided all other criteria are met, we recognize revenues on system sales when system acceptance provisions have been met in accordance with the terms and conditions of the arrangement. In the event that terms of the sale provide for a lapsing system acceptance period, we recognize revenue upon the expiration of the lapsing acceptance period or system acceptance, whichever occurs first. In these instances, which are infrequent, revenue is recorded only if the product has met product specifications prior to shipment and management deems that no significant uncertainties as to product performance exist.

Our transactions frequently include the sale of systems and services under multiple element arrangements. In transactions with multiple deliverables, revenue is recognized upon the delivery of the separate elements and when system acceptance has occurred or we are otherwise released from our system acceptance obligations.

For multiple element arrangements, the total consideration for an arrangement is allocated among the separate elements in the arrangement based on a selling price hierarchy. The selling price hierarchy for a deliverable is based on (i) vendor specific objective evidence (VSOE); if available; (ii) third party evidence of selling price if VSOE is not available; or (iii) an estimated selling price, if neither VSOE nor third party evidence is available. If we have not established VSOE and cannot obtain third party evidence of selling price, we determine our estimate of the relative selling price by considering our production costs and historical margins of similar products or services. We believe this best represents the price at which we would transact a sale if the product or service were sold on a stand-alone basis. We regularly review the method used to determine our relative selling price and update any estimates accordingly. We limit the amount of revenue recognized for delivered elements to the amount that is not contingent on the future delivery of products or services or other future performance obligations.

We generally recognize revenue from spare parts sales upon shipment, as our products are generally sold on terms that transfer title and risk of ownership when it leaves our site. We sell service contracts for which revenue is deferred and recognized ratably over the contract period (for time-based service contracts) or as service hours are delivered (for contracts based on a purchased quantity of hours). We recognize license revenue from transactions in which our systems are re-sold by our customers to third parties, as well as from royalty arrangements.

Costs related to deferred product revenues are capitalized (deferred) and recognized at the time of revenue recognition. Deferred product revenue and costs are netted on our balance sheet, under the caption “deferred product and services income.” The gross amount of deferred revenues and deferred costs at March 29, 2014 were $7.5 million and $1.2 million, respectively, as compared to $8.7 million and $2.2 million, respectively, at December 31, 2013.

Costs incurred for shipping and handling are included in cost of sales.
