Basis of Presentation	'
	Note 1—Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements of Veeco Instruments Inc. (together with its consolidated subsidiaries, “Veeco”, the “Company”, “we”, “us”, and “our”, unless the context indicates otherwise) have been prepared in accordance with accounting principles generally accepted in the United States (“U.S.”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S generally accepted accounting principles (“U.S. GAAP”) for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation (consisting of normal recurring accruals) have been included. Operating results for the three months ended March 31, 2014, are not necessarily indicative of the results that may be expected for the year ending December 31, 2014. For further information, refer to the consolidated financial statements and footnotes thereto included in our annual report on Form 10-K for the year ended December 31, 2013.
	Consistent with prior years, we report interim quarters, other than fourth quarters which always end on December 31, on a 13-week basis ending on the last Sunday of each period. The interim quarter ends are determined at the beginning of each year based on the 13-week quarters. The 2014 interim quarter ends are March 30, June 29 and September 28. The 2013 interim quarter ends were March 31, June 30 and September 29. For ease of reference, we report these interim quarter ends as March 31, June 30 and September 30 in our interim condensed consolidated financial statements. We have reclassified certain amounts previously reported in our financial statements to conform to the current presentation.
	Use of Estimates
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates made by management include: the best estimate of selling price for our products and services; allowance for doubtful accounts; inventory obsolescence; recoverability and useful lives of property, plant and equipment and identifiable intangible assets; investment valuations; fair value of derivatives; recoverability of goodwill and long lived assets; recoverability of deferred tax assets; liabilities for product warranty; accounting for acquisitions; accruals for contingencies; equity-based payments, including forfeitures and performance based vesting; and liabilities for tax uncertainties. Actual results could differ from those estimates.
	Income (Loss) Per Common Share
	The following table sets forth the reconciliation of basic weighted average shares outstanding and diluted weighted average shares outstanding (in thousands):
		Three months ended
		March 31,
		2014	2013
	Basic weighted average shares outstanding	39,177	38,716
	Dilutive effect of stock options and restricted stock	760	—
	Diluted weighted average shares outstanding	39,937	38,716
	Basic income (loss) per common share is computed using the weighted average number of common shares outstanding during the period. Diluted income (loss) per common share is computed using the weighted average number of common shares and common equivalent shares outstanding during the period. For the three months ended March 31, 2013, we reported a net loss applicable to common shareholders, and accordingly, the basic and diluted weighted average shares outstanding are equal because any increase to basic weighted average shares outstanding would be antidilutive. As a result, for the three months ended March 31, 2013, we excluded 0.5 million common equivalent shares that would have otherwise been dilutive.
	Additionally, not included above, were additional stock options and restricted stock outstanding that had exercise or grant prices in excess of the average market value of our common stock during the period and are therefore antidilutive. There were 1.4 million of such underlying shares for the three months ended March 31, 2014 and 2013, respectively.
	Revenue Recognition
	We recognize revenue when all of the following criteria have been met: persuasive evidence of an arrangement exists with a customer; delivery of the specified products has occurred or services have been rendered; prices are contractually fixed or determinable; and collectability is reasonably assured. Revenue is recorded including shipping and handling costs and excluding applicable taxes related to sales. A significant portion of our revenue is derived from contractual arrangements with customers that have multiple elements, such as systems, upgrades, components, spare parts, maintenance and service plans. For sales arrangements that contain multiple elements, we split the arrangement into separate units of accounting if the individually delivered elements have value to the customer on a standalone basis. We also evaluate whether multiple transactions with the same customer or related party should be considered part of a multiple element arrangement, whereby we assess, among other factors, whether the contracts or agreements are negotiated or executed within a short time frame of each other or if there are indicators that the contracts are negotiated in contemplation of each other. When we have separate units of accounting, we allocate revenue to each element based on the following selling price hierarchy: vendor-specific objective evidence (“VSOE”) if available; third party evidence (“TPE”) if VSOE is not available; or our best estimate of selling price (“BESP”) if neither VSOE nor TPE is available. We utilize BESP for the majority of the elements in our arrangements. The accounting guidance for selling price hierarchy did not include BESP for arrangements entered into prior to January 1, 2011, and as such we recognized revenue for those arrangements as described below.
	We consider many facts when evaluating each of our sales arrangements to determine the timing of revenue recognition, including the contractual obligations, the customer’s creditworthiness and the nature of the customer’s post-delivery acceptance provisions. Our system sales arrangements, including certain upgrades, generally include field acceptance provisions that may include functional or mechanical test procedures. For the majority of our arrangements, a customer source inspection of the system is performed in our facility or test data is sent to the customer documenting that the system is functioning to the agreed upon specifications prior to delivery. Historically, such source inspection or test data replicates the field acceptance provisions that will be performed at the customer’s site prior to final acceptance of the system. As such, we objectively demonstrate that the criteria specified in the contractual acceptance provisions are achieved prior to delivery and, therefore, we recognize revenue upon delivery since there is no substantive contingency remaining related to the acceptance provisions at that date, subject to the retention amount constraint described below. For new products, new applications of existing products or for products with substantive customer acceptance provisions where we cannot objectively demonstrate that the criteria specified in the contractual acceptance provisions have been achieved prior to delivery, revenue and the associated costs are deferred and fully recognized upon the receipt of final customer acceptance, assuming all other revenue recognition criteria have been met.
	Our system sales arrangements, including certain upgrades, generally do not contain provisions for right of return or forfeiture, refund, or other purchase price concessions. In the rare instances where such provisions are included, we defer all revenue until such rights expire. In many cases our products are sold with a billing retention, typically 10% of the sales price (the “retention amount”), which is typically payable by the customer when field acceptance provisions are completed. The amount of revenue recognized upon delivery of a system or upgrade, if any, is limited to the lower of i) the amount billed that is not contingent upon acceptance provisions or ii) the value of the arrangement consideration allocated to the delivered elements, if such sale is part of a multiple-element arrangement.
	For transactions entered into prior to January 1, 2011, under the accounting rules for multiple-element arrangements in place at that time, we deferred the greater of the retention amount or the relative fair value of the undelivered elements based on VSOE.  When we could not establish VSOE or TPE for all undelivered elements of an arrangement, revenue on the entire arrangement was deferred until the earlier of the point when we did have VSOE for all undelivered elements or the delivery of all elements of the arrangement.
	Our sales arrangements, including certain upgrades, generally include installation. The installation process is not deemed essential to the functionality of the equipment since it is not complex; that is, it does not require significant changes to the features or capabilities of the equipment or involve building elaborate interfaces or connections subsequent to factory acceptance. We have a demonstrated history of consistently completing installations in a timely manner and can reliably estimate the costs of such activities. Most customers engage us to perform the installation services, although there are other third-party providers with sufficient knowledge who could complete these services. Based on these factors, we deem the installation of our systems to be inconsequential or perfunctory relative to the system as a whole, and as a result, do not consider such services to be a separate element of the arrangement. As such, we accrue the cost of the installation at the time of revenue recognition for the system.
	In Japan, where our contractual terms with customers generally specify title and risk and rewards of ownership transfer upon customer acceptance, revenue is recognized and the customer is billed upon the receipt of written customer acceptance. During the fourth quarter of fiscal 2013, we began using a distributor for almost all of our product and service sales to customers in Japan. Title and risk and rewards of ownership of our system sales still transfer to our end-customers upon their acceptance.  As such, there is no impact to our policy of recognizing revenue upon receipt of written acceptance from the end customer.
	Revenue related to maintenance and service contracts is recognized ratably over the applicable contract term. Component and spare part revenue are recognized at the time of delivery in accordance with the terms of the applicable sales arrangement.
	Recent Accounting Pronouncements
	Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. In April 2014, the FASB issued ASU No. 2014-08 that changes the threshold for reporting discontinued operations and adds new disclosures. The new guidance defines a discontinued operation as a disposal of a component or group of components that is disposed of or is classified as held for sale and “represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results.” For disposals of individually significant components that do not qualify as discontinued operations, an entity must disclose pre-tax earnings of the disposed component. For public business entities, this guidance is effective prospectively for all disposals (or classifications as held for sale) of components of an entity that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements.
	Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or Tax Credit Carryforward Exists: In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or Tax Credit Carryforward Exists. ASU 2013-11 requires entities to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward when settlement in this manner is available under the tax law. This ASU is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. We adopted this as of January 1, 2014 and it did not have a material impact on our consolidated financial statements.
	Presentation of Financial Statements: In April 2013, the FASB issued ASU No. 2013-07, “Presentation of Financial Statements (Topic 205): Liquidation Basis of Accounting.” The objective of ASU 2013-07 is to clarify when an entity should apply the liquidation basis of accounting. The update provides principles for the recognition and measurement of assets and liabilities and requirements for financial statements prepared using the liquidation basis of accounting. This ASU is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. We adopted this as of January 1, 2014 and will evaluate the materiality of its impact on our consolidated financial statements when there are any indications that liquidation is imminent.
	Parent’s Accounting for the Cumulative Translation Adjustment: In March 2013, the FASB issued ASU No. 2013-05, Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity. This new standard is intended to resolve diversity in practice regarding the release into net income of a cumulative translation adjustment (“CTA”) upon derecognition of a subsidiary or group of assets within a foreign entity. ASU No. 2013-05 is effective prospectively for fiscal years (and interim reporting periods within those years) beginning after December 15, 2013. We have adopted this as of January 1, 2014 and currently anticipate that it could have an impact on our consolidated financial statements, in the event of derecognition of a foreign subsidiary in 2014 or subsequently. We cannot currently estimate the amount of CTA to be released into income from any potential derecognition.

	On October 1, 2013 (“the Acquisition Date”), Veeco acquired 100% of the outstanding common shares and voting interest of Synos Technology, Inc. (“Synos”). The results of Synos’ operations have been included in the consolidated financial statements since that date. Synos is an early stage manufacturer of fast array scanning atomic layer deposition (“FAST-ALD”) tools for OLED and other applications. As a result of the acquisition, the Company has entered the ALD market which is complimentary to the Company’s MOCVD LED offerings. The purchase price allocation is still preliminary.
	As part of Veeco’s acquisition agreement with Synos, there were certain contingent payments due to the selling shareholders of Synos dependent on the achievement of certain milestones. The aggregate fair value of the contingent consideration arrangement as of December 31, 2013 was $29.4 million.
	We estimate the fair value of acquisition-related contingent consideration based on management’s probability-weighted present value of the consideration expected to be transferred during the remainder of the earn-out period, based on the forecast related to the milestones. The fair value of the contingent consideration is reassessed by us on a quarterly basis based on a collaborative effort of our operations, finance and accounting groups using additional information as it becomes available. Any change in the fair value of an acquisition’s contingent consideration liability results in a remeasurement gain or loss that is recorded in the earnings of that period. As of March 31, 2014, we determined that the agreed upon post-closing milestones were not met or are not expected to be achieved and therefore reversed the remaining $29.4 million liability of the contingent consideration and recorded it as a change in contingent consideration in the Condensed Consolidated Statement of Operations.
	The post-closing milestones are divided into two contingencies. The first, tied to receipt of certain purchase orders, had an evaluation date of March 31, 2014, which, was not met and accounted for $20.2 million of the reversed liability. The second is based on achieving certain full year 2014 revenue and gross margin thresholds, which are unlikely to be met and accounted for $9.2 million of the reversed liability. As of March 31, 2014 the second contingency, with a maximum potential value of $75.0 million, remains contractually outstanding.

	Note 3—Income Taxes
	At the end of each interim reporting period, we estimate the effective income tax rate expected to be applicable for the full year. This estimate is used to determine the income tax provision or benefit on a year-to-date basis and may change in subsequent interim periods.
	Our effective tax rate for the three months ended March 31, 2014 was a benefit of 2.0% compared to a benefit of 48.2% during the three months ended March 31, 2013.  A tax benefit for each period was provided to the extent of future reversals of taxable temporary differences which relate primarily to tax deductible intangibles. Our effective tax rate for 2014 differed from the expected net operating loss carry forward benefit at the U.S. federal statutory rate of 35% primarily because of the inability to recognize such benefit due to uncertainties relating to future taxable income in terms of both its timing and its sufficiency, which would enable us to realize the federal carry forward benefit. The effective tax rate was also impacted because we did not provide a tax provision on the gain from the settlement of the contingent consideration related to the Synos acquisition. Our effective tax rate for 2013 differed from the U.S. federal statutory rate as a result of the jurisdictional mix of earnings in our foreign locations, an income tax benefit related to the generation of current year research and development tax credits, and legislation enacted in the first quarter of 2013 which extended the Federal Research and Development Credit for both the 2012 and 2013 tax years.

	During the three months ended March 31, 2014 and 2013, available-for-sale securities were liquidated for total proceeds of $32.0 million and $101.2 million, respectively. For the three months ended March 31, 2014 there were no realized gains on these liquidations, which were all maturities of investments. For the three months ended March 31, 2013 the gross realized gains on these sales were $0.1 million. The cost of securities sold is based on specific identification.
	The table below shows the fair value of short-term investments that have been in an unrealized loss position for less than 12 months (in thousands):

	We did not hold any short-term investments that have been in an unrealized loss position for 12 months or longer for the periods noted in the tables above.
	The Company regularly reviews its investment portfolio to identify and evaluate investments that have indications of possible impairment. Factors considered in determining whether an unrealized loss was considered to be temporary or other-than-temporary and therefore impaired include: the length of time and extent to which fair value has been lower than the cost basis; the financial condition and near-term prospects of the investee; and whether it is more likely than not that the Company will be required to sell the security prior to recovery. The Company believes the gross unrealized losses on the Company’s short-term investments as of March 31, 2014 and December 31, 2013 were temporary in nature and therefore did not recognize any impairment.
	Contractual maturities of available-for-sale debt securities are as follows (in thousands):
		March 31, 2014
		Estimated Fair Value
	Due in one year or less	$	207,913
	Due in 1–2 years	47,621
	Due in 2–3 years	11,868
	Total available-for-sale securities	$	267,402
	Actual maturities may differ from contractual maturities because some borrowers have the right to call or prepay obligations with or without call or prepayment penalties.
	Restricted Cash
	As of March 31, 2014 and December 31, 2013, restricted cash was $0.8 million and $2.7 million, respectively, which serves as collateral for bank guarantees that provide financial assurance that the Company will fulfill certain customer obligations. This cash is held in custody by the issuing bank and is restricted as to withdrawal or use while the related bank guarantees are outstanding.
	Accounts Receivable, Net
	Accounts receivable are presented net of allowance for doubtful accounts of $2.7 million and $2.4 million as of March 31, 2014 and December 31, 2013, respectively. We evaluate the collectability of accounts receivable based on a combination of factors. In cases where we become aware of circumstances that may impair a customer’s ability to meet its financial obligations subsequent to the original sale, we will record an allowance against amounts due, and thereby reduce the net recognized receivable to the amount the we reasonably believes will be collected. For all other customers, we recognize an allowance for doubtful accounts based on the length of time the receivables are past due and consideration of other factors such as industry conditions, the current business environment and its historical experience.

Property, Plant and Equipment, Net
As of March 31, 2014, we are holding $5.8 million of tools, that were previously used in our laboratories, for sale. These tools are carried in machinery and equipment, as a component of property, plant and equipment, net in our Condensed Consolidated Balance Sheets. These tools are the same type of tools we sell to our customers in the ordinary course of our business. During the three months ended March 31, 2014, we converted and sold $1.4 million of tools that we had previously used in our laboratories as Veeco Certified Equipment at an aggregate selling price of $2.3 million which is included in revenue in our Condensed Consolidated Statements of Operations.
Cost Method Investment
On September 28, 2010, we completed a $3.0 million investment in a rapidly developing organic light emitting diode (also known as OLED) equipment company (the “Investment”). We invested an additional $10.3 million and $1.2 million in the Investment during 2012 and 2011, respectively. In 2013, we invested an additional $2.4 million in the Investment in the form of bridge notes bearing 4% interest. The bridge notes are payable in equity at the time of a liquidity event or a qualifying equity investment round, otherwise they are payable in cash one year from the date of issuance. During the three months ended March 31, 2014, we invested an additional $0.2 million in the Investment in the form of additional bridge notes. Subsequent to quarter end, we invested an additional $0.6 million in the bridge notes. As of March 31, 2014 and December 31, 2013, we have a 15.4% ownership of the preferred shares, and effectively hold a 11.0% ownership interest of the total company. Since we do not exert significant influence on the Investment, this investment is treated under the cost method in accordance with applicable accounting guidance. This investment is recorded in other assets in our Condensed Consolidated Balance Sheets as of March 31, 2014 and December 31, 2013.
Customer Deposits and Deferred Revenue
As of March 31, 2014 and December 31, 2013, we had customer deposits of $31.3 million and $27.5 million, respectively recorded as a component of customer deposits and deferred revenue.
Accrued Warranty
We estimate the costs that may be incurred under the warranties we provide and record a liability in the amount of such costs at the time the related revenue is recognized. Factors that affect our warranty liability include product failure rates, material usage and labor costs incurred in correcting product failures during the warranty period. This accrual is recorded in accrued expenses and other current liabilities in our Condensed Consolidated Balance Sheets. We periodically assess the adequacy of our recognized warranty liability and adjust the amount as necessary. Changes in our warranty liability during the period are as follows (in thousands):
	March 31,
	2014			2013
Balance as of the beginning of period	$	5,662		$	4,942

Mortgage Payable
We have a mortgage payable with approximately $2.1 million outstanding as of March 31, 2014 and December 31, 2013. The mortgage accrues interest at an annual rate of 7.91%, and the final payment is due on January 1, 2020. We estimate the fair value of the mortgage as of March 31, 2014 and December 31, 2013 was approximately $2.2 million and $2.3 million, respectively.

Segment Information	'
	Note 5—Segment Information
	We have five identified operating segments that we aggregate into two reportable segments: the VIBE and Mechanical reporting units which are reported in our Data Storage segment; and the metal organic chemical vapor deposition (“MOCVD”), molecular beam epitaxy (“MBE”) and atomic layer deposition (“ALD”) reporting units are reported in our LED & Solar segment. We manage the business, review operating results and assess performance, as well as allocate resources, based upon our reporting units that reflect the market focus of each business. The LED & Solar segment consists of MOCVD systems, MBE systems, thermal deposition sources, ALD technology and other types of deposition systems. These systems are primarily sold to customers in the LED, OLED and solar industries, as well as to scientific research customers. This segment has product development and marketing sites in Somerset, New Jersey, Poughkeepsie, New York, St. Paul, Minnesota, Fremont, California, and Korea. The Data Storage segment consists of the ion beam etch, ion beam deposition, diamond-like carbon, physical vapor deposition, and dicing and slicing products sold primarily to customers in the data storage industry. This segment has product development and marketing sites in Plainview, New York, Ft. Collins, Colorado and Camarillo, California.
	We evaluate the performance of our reportable segments based on income (loss) from operations before interest, income taxes, amortization and certain items (“segment profit (loss)”), which is the primary indicator used to plan and forecast future periods. The presentation of this financial measure facilitates meaningful comparison with prior periods, as management believes segment profit (loss) reports baseline performance and thus provides useful information. Certain items include restructuring expenses, asset impairment charges, equity-based compensation expense and other non-recurring items. The accounting policies of the reportable segments are the same as those described in the summary of critical accounting policies.
	The following tables present certain data pertaining to our reportable segments and a reconciliation of segment profit (loss) to income (loss) before income taxes for the three months ended March 31, 2014 and 2013, respectively, and goodwill and total assets as of March 31, 2014 and December 31, 2013 (in thousands):

Fair Value Measurements	'
Fair Value Measurements	'
	Note 6— Fair Value Measurements
	We have categorized our assets and liabilities recorded at fair value based upon the fair value hierarchy. The levels of fair value hierarchy are as follows:
	·                  Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access.
	·                  Level 2 inputs utilize other-than-quoted prices that are observable, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, and inputs such as interest rates and yield curves that are observable at commonly quoted intervals.
	·                  Level 3 inputs are unobservable and are typically based on our own assumptions, including situations where there is little, if any, market activity.
	In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, we categorize such assets or liabilities based on the lowest level input that is significant to the fair value measurement in its entirety. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset.
	Both observable and unobservable inputs may be used to determine the fair value of positions that are classified within the Level 3 category. As a result, the unrealized gains and losses for assets within the Level 3 category may include changes in fair value that were attributable to both observable (e.g., changes in market interest rates) and unobservable (e.g., changes in historical company data) inputs.
	The major categories of assets and liabilities measured on a recurring basis, at fair value, as of March 31, 2014 and December 31, 2013, are as follows (in thousands):
		March 31, 2014

	Contingent consideration	—			—		(29,368		)	(29,368		)
	Highly liquid investments with maturities of three months or less when purchased may be classified as cash equivalents. Such items may include liquid money market accounts, U.S. treasuries, government agency securities and corporate debt. The investments that are classified as cash equivalents are carried at cost, which approximates fair value. Accordingly, no gains or losses (realized/unrealized) have been incurred for cash equivalents. All investments classified as available-for-sale are recorded at fair value within short-term investments in the Condensed Consolidated Balance Sheets.
	In determining the fair value of our investments and levels, through a third-party service provider, we use pricing information from pricing services that value securities based on quoted market prices in active markets and matrix pricing. Matrix pricing is a mathematical valuation technique that does not rely exclusively on quoted prices of specific investments, but on the investment’s relationship to other benchmarked quoted securities. We have a process in place for investment valuations to facilitate identification and resolution of potentially erroneous prices. We review the information provided by the third-party service provider to record the fair value of its portfolio.
	Consistent with Level 1 measurement principles, U.S. treasuries are priced using active market prices of identical securities. Consistent with Level 2 measurement principles, corporate debt, government agency securities, commercial paper, and derivative instruments are priced with matrix pricing.
	We estimate the fair value of acquisition-related contingent consideration based on management’s probability-weighted present value of the consideration expected to be transferred during the remainder of the earn-out period, based on forecast related to the milestones. The fair value of the contingent consideration is reassessed by us on a quarterly basis based on a collaborative effort of our operations, finance and accounting groups using additional information as it becomes available. Any change in the fair value of an acquisition’s contingent consideration liability results in a remeasurement gain or loss that is recorded in the earnings of that period. This fair value measure is based on significant inputs not observed in the market and thus represents a Level 3 measurement. Fair value measurements characterized within Level 3 of the fair value hierarchy are measured based on unobservable inputs that are supported by little or no market activity and reflect our own assumptions in measuring fair value.
	The significant unobservable inputs used in the fair value measurements of our acquisition-related contingent consideration include our measures of the probability of the achievement of certain agreed upon milestones and may include future profitability and related cash flows of the acquired business or assets, impacted by appropriate discount rates. Significant increases (decreases) in any of these inputs in isolation would result in a significantly lower (higher) fair value measurement. Generally, a change in the assumptions used for the discount rates is accompanied by a directionally opposite change in the fair value measurement and a change in the assumptions used for the future cash flows is accompanied by a directionally similar change in the fair value measurement.

	Note 7 — Derivative Financial Instruments
	We use derivative financial instruments to minimize the impact of foreign exchange rate changes on earnings and cash flows. In the normal course of business, our operations are exposed to fluctuations in foreign exchange rates. In order to reduce the effect of fluctuating foreign currencies on short-term foreign currency-denominated intercompany transactions and other known foreign currency exposures, we enter into monthly forward contracts. We do not use derivative financial instruments for trading or speculative purposes. Our forward contracts are not expected to subject us to material risks due to exchange rate movements because gains and losses on these contracts are intended to offset exchange gains and losses on the underlying assets and liabilities. The forward contracts are marked-to-market through earnings. We conduct our derivative transactions with highly rated financial institutions in an effort to mitigate any material counterparty risk.

	Restructuring and Other Charges
	During the three months ended March 31, 2014, we announced the consolidation of our Ft. Collins, Colorado facility into our Plainview, New York facility and took additional measures to improve profitability in a challenging business environment. We expect to substantially complete the consolidation by the end of 2014. We recorded restructuring charges of $0.4 million and notified approximately 49 employees of their termination from the Company. These charges consisted of personnel severance and related costs. We expect to incur approximately $1.3 million of additional restructuring charges in our Data Storage segment throughout the remainder of 2014 related to these actions. The reductions in head count principally relate to our Data Storage and MBE businesses.
	During the three months ended March 31, 2013, we took measures to improve profitability in a challenging business environment and notified approximately 20 employees of their termination from the Company. As a result, we recorded restructuring charges of $0.5 million consisting of personnel severance and related costs.

	Use of Estimates
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates made by management include: the best estimate of selling price for our products and services; allowance for doubtful accounts; inventory obsolescence; recoverability and useful lives of property, plant and equipment and identifiable intangible assets; investment valuations; fair value of derivatives; recoverability of goodwill and long lived assets; recoverability of deferred tax assets; liabilities for product warranty; accounting for acquisitions; accruals for contingencies; equity-based payments, including forfeitures and performance based vesting; and liabilities for tax uncertainties. Actual results could differ from those estimates.

	Basic weighted average shares outstanding	39,177	38,716
	Dilutive effect of stock options and restricted stock	760	—
	Diluted weighted average shares outstanding	39,937	38,716
	Basic income (loss) per common share is computed using the weighted average number of common shares outstanding during the period. Diluted income (loss) per common share is computed using the weighted average number of common shares and common equivalent shares outstanding during the period. For the three months ended March 31, 2013, we reported a net loss applicable to common shareholders, and accordingly, the basic and diluted weighted average shares outstanding are equal because any increase to basic weighted average shares outstanding would be antidilutive. As a result, for the three months ended March 31, 2013, we excluded 0.5 million common equivalent shares that would have otherwise been dilutive.
	Additionally, not included above, were additional stock options and restricted stock outstanding that had exercise or grant prices in excess of the average market value of our common stock during the period and are therefore antidilutive. There were 1.4 million of such underlying shares for the three months ended March 31, 2014 and 2013, respectively.
Revenue Recognition	'
	Revenue Recognition
	We recognize revenue when all of the following criteria have been met: persuasive evidence of an arrangement exists with a customer; delivery of the specified products has occurred or services have been rendered; prices are contractually fixed or determinable; and collectability is reasonably assured. Revenue is recorded including shipping and handling costs and excluding applicable taxes related to sales. A significant portion of our revenue is derived from contractual arrangements with customers that have multiple elements, such as systems, upgrades, components, spare parts, maintenance and service plans. For sales arrangements that contain multiple elements, we split the arrangement into separate units of accounting if the individually delivered elements have value to the customer on a standalone basis. We also evaluate whether multiple transactions with the same customer or related party should be considered part of a multiple element arrangement, whereby we assess, among other factors, whether the contracts or agreements are negotiated or executed within a short time frame of each other or if there are indicators that the contracts are negotiated in contemplation of each other. When we have separate units of accounting, we allocate revenue to each element based on the following selling price hierarchy: vendor-specific objective evidence (“VSOE”) if available; third party evidence (“TPE”) if VSOE is not available; or our best estimate of selling price (“BESP”) if neither VSOE nor TPE is available. We utilize BESP for the majority of the elements in our arrangements. The accounting guidance for selling price hierarchy did not include BESP for arrangements entered into prior to January 1, 2011, and as such we recognized revenue for those arrangements as described below.
	We consider many facts when evaluating each of our sales arrangements to determine the timing of revenue recognition, including the contractual obligations, the customer’s creditworthiness and the nature of the customer’s post-delivery acceptance provisions. Our system sales arrangements, including certain upgrades, generally include field acceptance provisions that may include functional or mechanical test procedures. For the majority of our arrangements, a customer source inspection of the system is performed in our facility or test data is sent to the customer documenting that the system is functioning to the agreed upon specifications prior to delivery. Historically, such source inspection or test data replicates the field acceptance provisions that will be performed at the customer’s site prior to final acceptance of the system. As such, we objectively demonstrate that the criteria specified in the contractual acceptance provisions are achieved prior to delivery and, therefore, we recognize revenue upon delivery since there is no substantive contingency remaining related to the acceptance provisions at that date, subject to the retention amount constraint described below. For new products, new applications of existing products or for products with substantive customer acceptance provisions where we cannot objectively demonstrate that the criteria specified in the contractual acceptance provisions have been achieved prior to delivery, revenue and the associated costs are deferred and fully recognized upon the receipt of final customer acceptance, assuming all other revenue recognition criteria have been met.
	Our system sales arrangements, including certain upgrades, generally do not contain provisions for right of return or forfeiture, refund, or other purchase price concessions. In the rare instances where such provisions are included, we defer all revenue until such rights expire. In many cases our products are sold with a billing retention, typically 10% of the sales price (the “retention amount”), which is typically payable by the customer when field acceptance provisions are completed. The amount of revenue recognized upon delivery of a system or upgrade, if any, is limited to the lower of i) the amount billed that is not contingent upon acceptance provisions or ii) the value of the arrangement consideration allocated to the delivered elements, if such sale is part of a multiple-element arrangement.
	For transactions entered into prior to January 1, 2011, under the accounting rules for multiple-element arrangements in place at that time, we deferred the greater of the retention amount or the relative fair value of the undelivered elements based on VSOE.  When we could not establish VSOE or TPE for all undelivered elements of an arrangement, revenue on the entire arrangement was deferred until the earlier of the point when we did have VSOE for all undelivered elements or the delivery of all elements of the arrangement.
	Our sales arrangements, including certain upgrades, generally include installation. The installation process is not deemed essential to the functionality of the equipment since it is not complex; that is, it does not require significant changes to the features or capabilities of the equipment or involve building elaborate interfaces or connections subsequent to factory acceptance. We have a demonstrated history of consistently completing installations in a timely manner and can reliably estimate the costs of such activities. Most customers engage us to perform the installation services, although there are other third-party providers with sufficient knowledge who could complete these services. Based on these factors, we deem the installation of our systems to be inconsequential or perfunctory relative to the system as a whole, and as a result, do not consider such services to be a separate element of the arrangement. As such, we accrue the cost of the installation at the time of revenue recognition for the system.
	In Japan, where our contractual terms with customers generally specify title and risk and rewards of ownership transfer upon customer acceptance, revenue is recognized and the customer is billed upon the receipt of written customer acceptance. During the fourth quarter of fiscal 2013, we began using a distributor for almost all of our product and service sales to customers in Japan. Title and risk and rewards of ownership of our system sales still transfer to our end-customers upon their acceptance.  As such, there is no impact to our policy of recognizing revenue upon receipt of written acceptance from the end customer.
	Revenue related to maintenance and service contracts is recognized ratably over the applicable contract term. Component and spare part revenue are recognized at the time of delivery in accordance with the terms of the applicable sales arrangement.

	Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. In April 2014, the FASB issued ASU No. 2014-08 that changes the threshold for reporting discontinued operations and adds new disclosures. The new guidance defines a discontinued operation as a disposal of a component or group of components that is disposed of or is classified as held for sale and “represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results.” For disposals of individually significant components that do not qualify as discontinued operations, an entity must disclose pre-tax earnings of the disposed component. For public business entities, this guidance is effective prospectively for all disposals (or classifications as held for sale) of components of an entity that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements.
	Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or Tax Credit Carryforward Exists: In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or Tax Credit Carryforward Exists. ASU 2013-11 requires entities to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward when settlement in this manner is available under the tax law. This ASU is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. We adopted this as of January 1, 2014 and it did not have a material impact on our consolidated financial statements.
	Presentation of Financial Statements: In April 2013, the FASB issued ASU No. 2013-07, “Presentation of Financial Statements (Topic 205): Liquidation Basis of Accounting.” The objective of ASU 2013-07 is to clarify when an entity should apply the liquidation basis of accounting. The update provides principles for the recognition and measurement of assets and liabilities and requirements for financial statements prepared using the liquidation basis of accounting. This ASU is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. We adopted this as of January 1, 2014 and will evaluate the materiality of its impact on our consolidated financial statements when there are any indications that liquidation is imminent.
	Parent’s Accounting for the Cumulative Translation Adjustment: In March 2013, the FASB issued ASU No. 2013-05, Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity. This new standard is intended to resolve diversity in practice regarding the release into net income of a cumulative translation adjustment (“CTA”) upon derecognition of a subsidiary or group of assets within a foreign entity. ASU No. 2013-05 is effective prospectively for fiscal years (and interim reporting periods within those years) beginning after December 15, 2013. We have adopted this as of January 1, 2014 and currently anticipate that it could have an impact on our consolidated financial statements, in the event of derecognition of a foreign subsidiary in 2014 or subsequently. We cannot currently estimate the amount of CTA to be released into income from any potential derecognition.
