MKS INSTRUMENTS, INC.
NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
(Tables in thousands, except share and per share data)
1)   Basis of Presentation
    The terms “MKS” and the “Company” refer to MKS Instruments, Inc. and its subsidiaries. The interim financial data as of June 30, 2011 and for the three and six months ended June 30, 2011 and 2010 are unaudited; however, in the opinion of MKS, the interim data includes all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the results for the interim periods. The consolidated balance sheet presented as of December 31, 2010 has been derived from the audited consolidated financial statements as of that date. The unaudited consolidated financial statements presented herein have been prepared in accordance with the instructions to Form 10-Q and do not include all of the information and note disclosures required by United States generally accepted accounting principles (“U.S. GAAP”). The consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the MKS Annual Report on Form 10-K for the year ended December 31, 2010 filed with the Securities and Exchange Commission on February 25, 2011.
    The preparation of these consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an on-going basis, management evaluates its estimates and judgments, including those related to revenue recognition, stock-based compensation, inventory, intangible assets, goodwill and other long-lived assets, acquisition expenses, income taxes and investments. Management bases its estimates and judgments on historical experience and on various other factors that are believed 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.
2)   Recently Issued Accounting Pronouncements
    In June 2011, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) which eliminates the option to present the components of other comprehensive income as part of the statement of equity and requires an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The amendments are effective retrospectively for fiscal years, and interim periods within those years, beginning after December 15, 2011. The ASU requires changes in presentation only and the Company does not expect it will have a material effect on its consolidated financial statements.
    In May 2011, the FASB issued an ASU which applies to all reporting entities that are required or permitted to measure or disclose the fair value of an asset, a liability, or an instrument classified in a reporting entity’s shareholders’ equity in the financial statements. The amendments do not extend the use of fair value accounting, but provide guidance on how it should be applied where its use is already required or permitted by other standards within U.S. GAAP. The amendments change the wording used to describe many requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements. Additionally, the ASU clarifies the FASB’s intent about the application of existing fair value measurements. The amendments in this ASU are to be applied prospectively. For public entities, the amendments are effective during interim and annual periods beginning after December 15, 2011. Early application by public entities is not permitted. The Company does not expect the new ASU to have a material effect on its financial position, results of operations or cash flows.
    In October 2009, the FASB issued an ASU that established new accounting and reporting provisions for arrangements including multiple revenue-generating activities. This ASU provides amendments to the criteria for separating deliverables, measuring and allocating arrangement consideration to one or more units of accounting. The amendments in this ASU also established a selling price hierarchy for determining the selling price of a deliverable. Significantly enhanced disclosures are also required to provide information about a vendor’s multiple-deliverable revenue arrangements, including information about the nature and terms, significant deliverables, and its performance within arrangements. The amendments also require providing information about the significant judgments made and changes to those judgments and about how the application of the relative selling-price method affects the timing or amount of revenue recognition. The amendments in this ASU were effective prospectively for revenue arrangements entered into or materially modified in the fiscal years beginning on or after June 15, 2010. The Company adopted the new ASU in the first quarter of 2011, and the adoption did not have a material impact on the Company’s financial position, results of operations or cash flows.

(Tables in thousands, except share and per share data)
    In October 2009, the FASB issued an ASU that changed the accounting model for revenue arrangements that include both tangible products and software elements that are “essential to the functionality,” and scoped these products out of current software revenue guidance. The new ASU includes factors to help companies determine what software elements are considered “essential to the functionality.” The amendments now subject software-enabled products to other revenue guidance and disclosure requirements, such as guidance surrounding revenue arrangements with multiple-deliverables. The amendments in this ASU were effective prospectively for revenue arrangements entered into or materially modified in the fiscal years beginning on or after June 15, 2010. The Company adopted the new ASU in the first quarter of 2011, and the adoption did not have a material impact on the Company’s financial position, results of operations or cash flows.

(1)   The cash and cash equivalent amounts presented in the tables above do not include cash amounts of $105,292,000 and $107,815,000 as of June 30, 2011 and December 31, 2010, respectively.
    Interest income is accrued as earned. Dividend income is recognized as income on the date the stock trades “ex-dividend.” The cost of marketable securities sold is determined by the specific identification method and realized gains or losses are reflected in income and were not material for the three and six months ended June 30, 2011 and 2010.
4)   Fair Value Measurements
    In accordance with the provisions of fair value accounting, a fair value measurement assumes that the transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability and defines fair value based upon an exit price model.
    The fair value measurement guidance establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The guidance describes three levels of inputs that may be used to measure fair value:
  Level 1   Quoted prices in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 1 assets and liabilities include money market funds and debt and equity securities.
 
  Level 2   Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange-traded instruments and derivative contracts whose value is determined using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. This category generally includes certain time deposits, time drafts and non-exchange traded derivative contracts.
 
  Level 3   Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.
    The following tables provide a summary of assets and liabilities of the Company measured at fair value on a recurring basis as of June 30, 2011 and December 31, 2010:

    Equity mutual funds
    As of June 30, 2011 and December 31, 2010, this asset class consisted of certain U.S. and international equity mutual funds, classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices in an active market for identical assets. The equity mutual funds are associated with the Company’s supplemental defined contribution retirement obligations.
    U.S. treasury and agency obligations
    As of June 30, 2011 and December 31, 2010, this asset class consisted of U.S. treasury and agency obligations classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices in an active market for identical assets.
    Derivatives
    As a result of the Company’s global operating activities, the Company is exposed to market risks from changes in foreign currency exchange rates, which may adversely affect its operating results and financial position. When deemed appropriate, the Company minimizes its risks from foreign currency exchange rate fluctuations through the use of derivative financial instruments. The principal market in which the Company executes its foreign currency contracts is the institutional market in an over-the-counter environment with a relatively high level of price transparency. The market participants usually are large commercial banks. The forward foreign currency exchange contracts are valued using broker quotations, or market transactions and are classified within Level 2 of the fair value hierarchy.
5)   Derivatives
    The Company enters into derivative instruments for risk management purposes only, including derivatives designated as hedging instruments and those utilized as economic hedges. The Company operates internationally and, in the normal course of business, is exposed to fluctuations in interest rates and foreign exchange rates. These fluctuations can increase the costs of financing, investing and operating the business. The Company has used derivative instruments, such as forward contracts, to manage certain foreign currency exposure.
    By nature, all financial instruments involve market and credit risks. The Company enters into derivative instruments with major investment grade financial institutions and no collateral is required. The Company has policies to monitor the credit risk of these counterparties. While there can be no assurance, the Company does not anticipate any material non-performance by any of these counterparties.
    The Company hedges a portion of its forecasted foreign currency denominated intercompany sales of inventory, over a maximum period of eighteen months, using forward foreign exchange contracts accounted for as cash-flow hedges related to Japanese, South Korean, British and European currencies. To the extent these derivatives are effective in off-setting the variability of the hedged cash flows, and otherwise meet the hedge accounting criteria, changes in the derivatives’ fair value are not included in current earnings but are included in other comprehensive income (“OCI”) in stockholders’ equity. These changes in fair value will subsequently be reclassified into earnings, as applicable, when the forecasted transaction occurs. To the extent that a previously designated hedging transaction is no longer an effective hedge, any ineffectiveness measured in the hedging relationship is recorded currently in earnings in the period it occurs. The cash flows resulting from forward exchange contracts are classified in the consolidated statements of cash flows as part of cash flows from operating activities. The Company does not enter into derivative instruments for trading or speculative purposes.
    To the extent the hedge accounting criteria is not met, the related foreign currency forward contracts are considered as economic hedges and changes in the fair value of these contracts are recorded immediately in earnings in the period in which they occur. These include hedges that are used to reduce exchange rate risks arising from the change in fair value of certain foreign currency denominated assets and liabilities (i.e., payables, receivables) and other economic hedges where the hedge accounting criteria were not met.

7)   Goodwill and Intangible Assets
    Goodwill
    The Company tests goodwill for impairment on an annual basis, which has been determined to be as of October 31 of each fiscal year. The Company also tests goodwill between annual tests if an event occurs or circumstances change that indicate that the fair value of a reporting unit may be below its carrying value.
    Goodwill impairment is determined using a two-step process. The first step involves a comparison of the estimated fair value of a reporting unit to its carrying amount, including goodwill. In performing the first step, the Company determines the fair value of a reporting unit using a discounted cash flow (“DCF”) analysis. Determining fair value requires the exercise of significant judgment, including judgments about appropriate discount rates, perpetual growth rates, and the amount and timing of expected future cash flows. Discount rates are based on a weighted average cost of capital (“WACC”), which represents the average rate a business must pay its providers of debt and equity. The WACC used to test goodwill was derived from a group of comparable companies. The cash flows employed in the DCF analysis were derived from internal earnings and forecasts and external market forecasts. If the estimated fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired and the second step of the impairment test is not necessary. If the carrying amount of a reporting unit exceeds its estimated fair value, then the second step of the goodwill impairment test must be performed.
    The second step of the goodwill impairment test compares the implied fair value of the reporting unit’s goodwill with its carrying amount of goodwill to measure the amount of impairment loss, if any. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination, whereby the estimated fair value of the reporting unit is allocated to all of the assets and liabilities of that unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination and the fair value of the reporting unit was the purchase price paid. If the carrying amount of the reporting unit’s goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess.
    As of October 31, 2010, the Company performed its annual impairment assessment of goodwill and determined that no impairment charges were required, as the fair value of each reporting unit exceeded its book value.
    The changes in the carrying amount of goodwill and accumulated impairment losses during the six months ended June 30, 2011 and twelve months ended December 31, 2010 were as follows:
                                                 
    2011     2010  
    Gross     Accumulated             Gross     Accumulated

(1)   In November 2010, the Company purchased a technology company for $2,447,000 to enhance its product portfolio. The Company recorded $2,292,000 of goodwill in connection with the acquisition.

(2)   In May 2010, the Company sold its Ion Systems, Inc. (“Ion”) business and in August 2010 it sold the assets of its Yield Dynamics, LLC (“YDI”) business and as a result charged the related net goodwill to the gain on sale of discontinued operations.
    Intangible Assets
    Components of the Company’s intangible assets are comprised of the following:
                         
            Accumulated        
    Gross     Amortization     Net  
     
As of June 30, 2011:

  $ 110,407     $ (109,164 )   $ 1,243  
     
                         
            Accumulated        
    Gross     Amortization     Net  
     
As of December 31, 2010

  $ 76,829     $ (76,230 )   $ 599  
Customer relationships
    8,940       (8,083 )     857

    24,638       (24,351 )     287  
     
 
  $ 110,407     $ (108,664 )   $ 1,743  
     
    Aggregate amortization expense related to intangible assets for the three and six months ended June 30, 2011 was $250,000 and $500,000, respectively. Aggregate amortization expense related to intangible assets for the three and six months ended June 30, 2010 was $314,000 and $783,000, respectively. Estimated amortization expense for each of the three remaining fiscal years is as follows:
         
Year
  Amount
2011 (remaining)
  $ 488  
2012
    389  
2013
    366  
8)   Debt
    The Company’s Japanese subsidiary has lines of credit and short-term borrowing arrangements with two financial institutions which provide for aggregate borrowings as of June 30, 2011 of up to an equivalent of $30,941,000 U.S. dollars, which generally expire and are renewed at three month intervals. At June 30, 2011 total borrowings outstanding under these arrangements were $619,000 at an interest rate of 0.68%. There were no borrowings outstanding at December 31, 2010.
9)   Product Warranties
    The Company provides for the estimated costs to fulfill customer warranty obligations upon the recognition of the related revenue. While the Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of its component suppliers, the Company’s warranty obligation is affected by shipment volume, product failure rates, utilization levels, material usage, and supplier warranties on parts delivered to the Company. Should actual product failure rates, utilization levels, material usage, or supplier warranties on parts differ from the Company’s estimates, revisions to the estimated warranty liability would be required. The product warranty liability is included in other current liabilities in the consolidated balance sheets.
    Product warranty activities were as follows:
                 
    Six Months Ended June 30,
    2011   2010
     
Balance at January 1
  $ 9,865     $ 6,560  
Provision for product warranties
    3,638       4,731  
Direct charges to warranty liability
    (3,832 )     (2,309 )
     
Balance at June 30
  $ 9,671     $ 8,982

10)   Income Taxes
    The Company’s effective tax rate for both the three and six months ended June 30, 2011 was 33.0%. The Company’s effective tax rate for the three and six months ended June 30, 2010 was 34.0% and 33.0%, respectively. The effective tax rates for the six months ended June 30, 2011 and 2010, and the related income tax provisions were lower than the U.S. statutory tax rate primarily due to the geographic mix of income and profits earned by the Company’s international subsidiaries being taxed at rates lower than the U.S. statutory rate.
    At June 30, 2011, the total amount of gross unrecognized tax benefits, which excludes interest and penalties, was approximately $16,749,000. At December 31, 2010, the total amount of gross unrecognized tax benefits, which excludes interest and penalties, was approximately $15,270,000. The net increase from December 31, 2010 was primarily attributable to an increase in reserves for existing uncertain tax positions. If these benefits were recognized in a future period, the timing of which is not estimable, the net unrecognized tax benefit of $12,789,000, excluding interest and penalties, would impact the Company’s effective tax rate. The Company accrues interest expense and, if applicable, penalties for any uncertain tax positions. Interest and penalties are classified as a component of income tax expense. At June 30, 2011 and December 31, 2010, the Company had accrued interest on unrecognized tax benefits of approximately $1,253,000 and $986,000, respectively.
    The Company and its subsidiaries are subject to examination by federal, state and foreign tax authorities. The statute of limitations for the Company’s tax filings varies by tax jurisdiction between fiscal years 2001 through present.
    While the Company believes it has adequately provided for all tax positions, amounts asserted by taxing authorities could materially differ from the Company’s accrued positions as a result of uncertain and complex application of tax regulations. Additionally, the recognition and measurement of certain tax benefits include estimates and judgment by management and inherently includes subjectivity. Accordingly, the Company could record additional provisions or benefits due to U.S. federal, state, and foreign tax-related matters in the future as it revises estimates or settles or otherwise resolves the underlying matters.
11)   Discontinued Operations
    During the second quarter of 2010, the Company committed to a plan to divest two product lines, as their growth potential no longer met the Company’s long-term strategic objectives. The Company completed the sale of Ion on May 17, 2010 for $15,097,000 of net cash proceeds after expenses and recorded a pre-tax gain on the sale of $4,228,000. As a result of committing to a plan to divest a second product line and, therefore, meeting the asset held for sale criteria, during the second quarter of 2010, the Company performed a fair value analysis of its YDI business in order to measure it at the lower of its carrying value or fair value less cost to dispose. Based on the analysis, the Company determined that the carrying value was less than the fair value, less costs to dispose, and therefore, no impairment charge was required. The YDI business was considered held for sale of June 30, 2010. The Company completed the sale of the assets of its YDI business on August 11, 2010 for $490,000 of net cash proceeds after expenses and recorded a pre-tax gain on the sale of $224,000.
    The two product lines have been accounted for as discontinued operations. Accordingly, their results of operations have been reclassified to discontinued operations in the consolidated statements of operations for all periods presented. The assets and liabilities of these discontinued businesses have not been reclassified or segregated in the consolidated balance sheets or consolidated statements of cash flows due to their immaterial amounts. Net revenues and income from discontinued operations for the three and six months ended June 30, 2011 and 2010 are below:
                                 
    Three Months Ended     Six Months Ended

    Basic earnings per share (“EPS”) is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding during the period. The computation of diluted EPS is similar to the computation of basic EPS except that the denominator is increased to include the number of additional common shares that would have been outstanding (using the treasury stock method) if securities containing potentially dilutive common shares (stock options and restricted stock units) had been converted to such common shares, and if such assumed conversion is dilutive.
    As of June 30, 2011, stock options and restricted stock units relating to an aggregate of approximately 1,638,000 shares were outstanding. For the three and six months ended June 30, 2011, the potential dilutive effect of 331,000 and 256,000 weighted-average shares, respectively, of restricted stock units and stock options were excluded from the computation of diluted weighted-average shares outstanding as the shares would have an anti-dilutive effect on EPS.
    As of June 30, 2010, stock options and restricted stock units relating to an aggregate of approximately 3,637,000 shares were outstanding. For the three and six months ended June 30, 2010, the potential dilutive effect of 1,201,000 and 1,295,000 weighted-average shares, respectively, of restricted stock units and stock options were excluded from the computation of diluted weighted-average shares outstanding as the shares would have an anti-dilutive effect on EPS.

     This Quarterly Report on Form 10-Q contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act and Section 21E of the Securities Exchange Act. When used herein, the words “believes,” “anticipates,” “plans,” “expects,” “estimates,” “would,” “will,” “intends” and similar expressions are intended to identify forward-looking statements. These forward-looking statements reflect management’s current opinions and are subject to certain risks and uncertainties that could cause results to differ materially from those stated or implied. While we may elect to update forward looking statements at some point in the future, we specifically disclaim any obligation to do so even if our estimates or expectations change. Risks and uncertainties include, but are not limited to those discussed in our Annual Report on Form 10-K for the year ended December 31, 2010 in the section entitled “Risk Factors” as referenced in Part II, Item 1A “Risk Factors” of this Quarterly Report on Form 10-Q.
Overview
     We are a leading global provider of instruments, subsystems and process control solutions that measure, control, power, monitor and analyze critical parameters of advanced manufacturing processes to improve process performance and productivity. We also provide services relating to the maintenance and repair of our products, software maintenance, installation services and training.
     Our products are used in diverse markets, applications and processes. The primary markets we serve are manufacturers of capital equipment for semiconductor devices and for other thin film applications including flat panel displays, light emitting diodes (“LEDs”), solar cells, data storage media and other advanced coatings. We also leverage our technology into other markets with advanced manufacturing applications including medical equipment, pharmaceutical manufacturing, energy generation and environmental monitoring.
     We are managed as one operating segment. We group our products into three product groups: Instruments and Control Systems, Power and Reactive Gas Products and Vacuum Products. Our products are derived from our core competencies in pressure measurement and control, materials delivery, gas composition analysis, control and information technology, power and reactive gas generation and vacuum technology.
     We have a diverse base of customers that includes manufacturers of semiconductor capital equipment and semiconductor devices, thin film capital equipment used in the manufacture of flat panel displays, LEDs, solar cells, data storage media, and other coating applications; and industrial, medical, pharmaceutical manufacturing, energy generation, environmental monitoring and other advanced manufacturing companies, as well as university, government and industrial research laboratories. For the six months ended June 30, 2011 and the full year ended December 31, 2010, we estimate that 62% and 64% of our net sales, respectively, were to semiconductor capital equipment manufacturers and semiconductor device manufacturers. We expect that sales to semiconductor capital equipment manufacturers and semiconductor device manufacturers will continue to account for a substantial portion of our sales.
     Through the second quarter of 2011, we saw an improvement in the global economy, which contributed to an increase in our business, financial condition and results of operations for the six months ended June 30, 2011 compared to the same period for the prior year. As a result of the improved global economy, our net revenues to semiconductor capital equipment manufacturers and semiconductor device manufacturers increased 7% for the six months ended June 30, 2011 compared to the same period for the prior year. Although our business levels increased for the six months ended June 30, 2011 compared to the same period for the prior year, the semiconductor capital equipment industry is subject to rapid demand shifts, which are difficult to predict, and we are uncertain as to the timing or extent of future demand or any future weakness in the semiconductor capital equipment industry. As we recently reported, we have recently begun to see a moderation in our semiconductor capital equipment manufacture and semiconductor devise manufacture customers’ order rates.
     Our net revenues sold to other advanced markets, which exclude semiconductor capital equipment and semiconductor device product applications, increased 18% for the six months ended June 30, 2011 compared to the same period for the prior year. The increase was mainly due to product revenues from a thin film solar customer in China during the first quarter of 2011. These advanced and growing markets include LED, medical, biopharm, environmental, thin films, solar and other markets and we anticipate that these markets will continue to grow and will represent a larger portion of our revenue.
     A significant portion of our net sales is to customers in international markets. International net sales include sales by our foreign subsidiaries, but exclude direct export sales. For the six months ended June 30, 2011 and the year ended December 31, 2010, international net sales accounted for approximately 52% and 43% of our net sales, respectively. A significant portion of our international net sales were in Japan and China. We expect that international net sales will continue to represent a significant percentage of our total net sales.

     Product revenues decreased $0.2 million and increased $36.2 million during the three and six months ended June 30, 2011, respectively, compared to the same periods for the prior year. For the three months ended June 30, 2011 our product revenues related to our semiconductor capital equipment manufacturer and semiconductor device manufacturer customers increased by $2.9 million, or 2.3%. Although we have seen a recovery in the global economy since late 2009, which has contributed to an increase in demand for our products in many of the markets we serve, we have recently seen a moderation in our semiconductor capital equipment manufacturer and semiconductor device manufacturer customers’ order rates. Our product revenues sold to other advanced markets, which exclude semiconductor capital equipment and semiconductor device product applications decreased $3.1 million, or 4.3%, during the three months ended June 30, 2011 compared to the same period for the prior year primarily due to a reduction in product sales to the solar market.
     For the six months ended June 30, 2011 our product revenues related to our semiconductor capital equipment manufacturer and semiconductor device manufacturer customers increased by $17.3 million, or 7.4%. Our product revenues sold to other advanced markets, which exclude semiconductor capital equipment and semiconductor device product applications increased $18.9 million, or 13.8% during the

six months ended June 30, 2011 compared to the same period for the prior year. The increase in demand in our other markets included the LED, biopharm, environmental, thin films, solar and other markets. A significant portion of this increase was due to product revenues from a thin film solar customer in China during the first quarter of 2011.
     Service revenues consisted mainly of fees for services relating to the maintenance and repair of our products, software maintenance, installation services and training. Service revenues increased $4.1 million, or 18.6%, and $7.3 million, or 17.1%, during the three and six months ended June 30, 2011, respectively, compared to the same periods for the prior year, as a result of the improvement in the global economy, increase in product sales and due to our investment to grow our service business in Asia.
     Total international net revenues, including product and service, were $114.1 million, and $235.3 million, or 50.8% and 51.6% of net revenues for the three and six months ended June 30, 2011, respectively. Total international net revenues, including product and service, were $92.6 million, and $172.0 million, or 42.0% and 41.7% of net revenues, for the three and six months ended June 30, 2010, respectively. The increases are due to a general increase in worldwide demand from many of the markets we serve as a result of improvement in the global economy. A significant portion of the increase in international net revenues for the six months ended June 30, 2011 was due to product revenues from a thin film solar customer in China during the first quarter of 2011.

     Gross profit on product revenues increased by 3.0 percentage points for the three months ended June 30, 2011, compared to the same period for the prior year. The increase is due to an increase of 4.8 percentage points due to favorable product mix and an increase of 1.0 percentage points from favorable foreign exchange fluctuations. These increases were partially offset by 1.8 percentage points due to higher overhead and 1.4 percentage points related to higher excess and obsolete inventory related net charges. The higher overhead spending is due to higher salary and fringe related costs for additional personnel due to the higher business levels and an increase in incentive compensation.
     Gross profit on product revenues increased by 2.3 percentage points for the six months ended June 30, 2011, compared to the same period for the prior year. The increase is due to an increase of 4.4 percentage points due to favorable product mix, and an increase of 0.9 percentage points from favorable foreign exchange fluctuations. These increases were partially offset by 1.9 percentage points due to higher overhead and 1.0 percentage points related to higher excess and obsolete inventory related net charges. The higher overhead spending is due to higher salary and fringe related costs for additional personnel due to the higher business levels and an increase in incentive compensation.
     Cost of service revenues consists primarily of costs of providing services for repair and training which includes salaries and related expenses and other fixed costs. Service gross profit increased by 0.2 percentage points and 0.6 percentage points for the three and six months ended June 30, 2011, respectively, compared to the same periods for the prior year. The increase is mainly a result of higher service revenues since a majority of our overhead costs are fixed.

     Research and development expense decreased $0.6 million during the three months ended June 30, 2011, compared to the same period for the prior year. The decrease includes a $0.4 million decrease in spending on project materials due to changes in the timeline of certain projects and a $0.2 million decrease in patent and other legal related costs.
     Research and development expense increased $0.7 million during the six months ended June 30, 2011, compared to the same period for the prior year. The increase includes a $1.2 million increase in compensation expense and a $0.2 million increase in patent and other legal related costs offset by a $0.9 million decrease in spending on project materials. The increase in compensation expense is due to higher salary costs for additional personnel and an increase in stock-based compensation costs. In addition, compensation costs increased as fringe related costs were higher as a result of increased taxes related to an incentive compensation payment and the restoration in the second quarter of 2010 of the employer match portion of the 401(k) profit-sharing plan and employee stock purchase plans.

Table of Contents

     Our research and development is primarily focused on developing and improving our instruments, components, subsystems and process control solutions to improve process performance and productivity.
     We have thousands of products and our research and development efforts primarily consist of a large number of projects related to these products, none of which is individually material to us. Current projects typically have a duration of 3 to 30 months depending upon whether the product is an enhancement of existing technology or a new product. Our current initiatives include projects to enhance the performance characteristics of older products, to develop new products and to integrate various technologies into subsystems. These projects support in large part the transition in the semiconductor industry to smaller integrated circuit geometries and in the flat panel display and solar markets to larger substrate sizes, which require more advanced process control technology. Research and development expenses consist primarily of salaries and related expenses for personnel engaged in research and development, fees paid to consultants, material costs for prototypes and other expenses related to the design, development, testing and enhancement of our products as well as legal costs associated with maintaining and defending our intellectual property.
     We believe that the continued investment in research and development and ongoing development of new products are essential to the expansion of our markets, and we expect to continue to make significant investment in research and development activities. We are subject to risks if products are not developed in a timely manner, due to rapidly changing customer requirements and competitive threats from other companies and technologies. Our success primarily depends on our products being designed into new generations of equipment for the semiconductor industry and other advanced technology markets. We develop products that are technologically advanced so that they are positioned to be chosen for use in each successive generation of semiconductor capital equipment. If our products are not chosen to be designed into our customers’ products, our net revenues may be reduced during the lifespan of those products.

     Interest income, net was unchanged for the three and six months ended June 30, 2011 compared to the same periods for the prior year. Although the total cash and marketable securities balance was approximately $170 million higher on average for the six months ended June 30, 2011 compared to the same period for the prior year, interest income, net was unchanged due to a reduction in interest rates and a change in the mix of the investment portfolio.

     Our effective tax rate for both the three and six months ended June 30, 2011 was 33.0%. Our effective tax rate for the three and six months ended June 30, 2010 was 34.0% and 33.0%, respectively. The effective tax rates for the six months ended June 30, 2011 and 2010, and the related income tax provisions were lower than the U.S. statutory tax rate primarily due to the geographic mix of income and profits earned by our international subsidiaries being taxed at rates lower than the U.S. statutory rate.
     At June 30, 2011, our total amount of gross unrecognized tax benefits, which excludes interest and penalties, was approximately $16.7 million. At December 31, 2010, our total amount of gross unrecognized tax benefits, which excludes interest and penalties, was approximately $15.3 million. The net increase from December 31, 2010 was primarily attributable to an increase in reserves for existing uncertain tax positions. If these benefits were recognized in a future period, the timing of which is not estimable, the net unrecognized tax benefit of $12.8 million, excluding interest and penalties, would impact our effective tax rate. We accrue interest expense and, if applicable, penalties for any uncertain tax positions. Interest and penalties are classified as a component of income tax expense. At June 30, 2011 and December 31, 2010, we had accrued interest on unrecognized tax benefits of approximately $1.3 million and $1.0 million, respectively.
     We and our subsidiaries are subject to examination by federal, state and foreign tax authorities. The statute of limitations for our tax filings varies by tax jurisdiction between fiscal years 2001 through present.
     Our future effective income tax rate depends on various factors, such as tax legislation and the geographic composition of our pre-tax income. We monitor these factors and timely adjust our effective tax rate accordingly. Additionally, the effective tax rate could be adversely affected by changes in the valuation of deferred tax assets and liabilities. In particular, the carrying value of deferred tax assets, which are predominantly in the United States, is dependent on our ability to generate sufficient future taxable income in the United States. While we believe we have adequately provided for all tax positions, amounts asserted by taxing authorities could materially differ from our accrued positions as a result of uncertain and complex application of tax regulations. Additionally, the recognition and measurement of certain tax benefits include estimates and judgment by management and inherently includes subjectivity. Accordingly, we could record additional provisions or benefits due to U.S. federal, state, and foreign tax-related matters in the future as we revise estimates or settle or otherwise resolve the underlying matters.

     During the second quarter of 2010, we committed to a plan to divest two product lines as their growth potential no longer met our long-term strategic objectives. We completed the sale of Ion Systems, Inc. in May 2010 for $15.1 million of net cash proceeds after expenses and recorded a pre-tax gain on the sale of $4.2 million. We sold of the assets of our Yield Dynamics, LLC business in August 2010 for a total of $0.5 million of net cash proceeds after expenses and recorded a $0.2 million pre-tax gain on the sales.
     The two product lines have been accounted for as discontinued operations. Accordingly, their results of operations have been reclassified to discontinued operations in the consolidated statements of operations for 2010. The assets and liabilities of these discontinued product lines have not been reclassified or segregated in the consolidated balance sheets or consolidated statements of cash flows due to their immaterial amounts.

Liquidity and Capital Resources
     Cash, cash equivalents, long-term and short-term investments totaled $501.6 million at June 30, 2011 compared to $431.9 million at December 31, 2010. This increase was mainly attributable to our net cash provided by operating activities as a result of our net income and net proceeds related to employee stock awards, partially offset by dividend payments to our common shareholders and capital expenditures.
     Net cash provided by operating activities of $58.7 million for the six months ended June 30, 2011, resulted mainly from net income of $76.6 million which included non-cash charges of $18.9 million, partially offset by an increase of $34.4 million in working capital. The increase in working capital consisted primarily of a $12.9 million increase in inventory and an $11.0 million increase in trade accounts receivable, both a result of our increased business levels, and a $9.9 million increase in other current assets partially due to an increase in our value-added tax receivable.
     Net cash provided by operating activities of $39.2 million for the six months ended June 30, 2010, resulted mainly from net income of $68.0 million and non-cash charges of $16.3 million, partially offset by a $41.8 million change in working capital. The increase in working capital consisted primarily of a $58.0 million increase in trade accounts receivable and an increase of $28.3 million of inventory as a result of our increased business levels. The increase in net operating assets was partially offset by an increase of $14.0 million in accounts payable related to inventory purchases to support our increased business levels, an increase of $17.3 million in accrued compensation and an increase of $10.4 million in accrued liabilities. The increase in accrued liabilities is mainly related to an increase in non-income taxes payable.
     Net cash used in investing activities of $11.1 million for the six months ended June 30, 2011, resulted primarily from $6.3 million in purchases of production related equipment and the net purchases of $4.6 million of short-term and long-term available-for-sale investments. Net cash provided by investing activities of $1.9 million for the six months ended June 30, 2010, resulted primarily from $15.1 million in net proceeds from the sale of a discontinued operation and proceeds of $2.1 million from the sale of two vacated facilities, partially offset by $7.2 million of net purchases of available-for-sale investments and by $6.6 million in purchases of property, plant and equipment.
     Net cash provided by financing activities was $14.9 million for the six months ended June 30, 2011 and consisted primarily of $29.3 million cash received from the exercise of previously issued stock options and $5.2 million from excess tax benefits from stock-based compensation. These increases were partially offset by two dividend payments to common stockholders of an aggregate of $15.6 million and $5.1 million in taxes paid upon the vesting of restricted stock units. Net cash provided by financing activities was $2.4 million for the six months ended June 30, 2010 and consisted primarily of $2.3 million related to cash received from the exercise of previously issued stock options.
     Our Japanese subsidiary has lines of credit and short-term borrowing arrangements with two financial institutions which provide for aggregate borrowings as of June 30, 2011 of up to an equivalent of $30.9 million U.S. dollars, which generally expire and are renewed at three month intervals. At June 30, 2011 total borrowings outstanding under these arrangements were $0.6 million at an interest rate of 0.68%. There were no borrowings outstanding at December 31, 2010.
     On July 25, 2011, our Board of Directors approved a share repurchase program for the repurchase of up to an aggregate of $200 million of our common stock from time to time in open market purchases, privately negotiated transactions or through other appropriate means. The timing and quantity of any shares repurchased will depend upon a variety of factors, including business conditions, stock market conditions and business development activities, including but not limited to merger and acquisition opportunities. These repurchases may be commenced, suspended or discontinued at any time without prior notice.
     On July 25, 2011, our Board of Directors authorized a quarterly cash dividend of $0.15 per share, payable on September 16, 2011 to shareholders of record as of September 1, 2011. On May 2, 2011, our Board of Directors authorized a quarterly cash dividend of $0.15 per share, paid on June 17, 2011 to shareholders of record as of June 1, 2011. Our cash payment for the dividend on June 17, 2011 was $7.9 million. On February 1, 2011, our Board of Directors authorized a quarterly cash dividend of $0.15 per share, paid on March 18, 2011 to shareholders of record as of March 1, 2011. Our cash payment for the dividend on March 18, 2011 was $7.8 million. Future dividend declarations, if any, as well as the record and payment dates for such dividends, are subject to the final determination of our Board of Directors.
     We believe that our current cash position and available borrowings will be sufficient to satisfy our estimated working capital and planned capital expenditure requirements through at least the next 12 months and the foreseeable future.
Off-Balance Sheet Arrangements
     We do not have any financial partnerships with unconsolidated entities, such as entities often referred to as structured finance, special purpose entities or variable interest entities, which are often established for the purpose of facilitating off-balance sheet arrangements or for other contractually narrow or limited purposes. Accordingly, we have no off-balance sheet arrangements that have or are reasonably expected

to have a current or future effect on our financial condition, results of operations, liquidity, capital expenditures or capital resources that are material to investors.
Contractual Obligations
     We reviewed our contractual obligations and commercial commitments as of June 30, 2011 and determined that there were no significant changes from the ones set forth in the notes to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2010.
Recently Issued Accounting Pronouncements
     In June 2011, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) which eliminates the option to present the components of other comprehensive income as part of the statement of equity and requires an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The amendments are effective retrospectively for fiscal years, and interim periods within those years, beginning after December 15, 2011. The ASU requires changes in presentation only and we do not expect it will have a material effect on our consolidated financial statements.
     In May 2011, the FASB issued an ASU which applies to all reporting entities that are required or permitted to measure or disclose the fair value of an asset, a liability, or an instrument classified in a reporting entity’s shareholders’ equity in the financial statements. The amendments do not extend the use of fair value accounting, but provide guidance on how it should be applied where its use is already required or permitted by other standards within U.S. GAAP. The amendments change the wording used to describe many requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements. Additionally, the ASU clarifies the FASB’s intent about the application of existing fair value measurements. The amendments in this ASU are to be applied prospectively. For public entities, the amendments are effective during interim and annual periods beginning after December 15, 2011. Early application by public entities is not permitted. We do not expect the new ASU to have a material effect on our financial position, results of operations or cash flows.
     In October 2009, the FASB issued an ASU that established new accounting and reporting provisions for arrangements including multiple revenue-generating activities. This ASU provides amendments to the criteria for separating deliverables, measuring and allocating arrangement consideration to one or more units of accounting. The amendments in this ASU also established a selling price hierarchy for determining the selling price of a deliverable. Significantly enhanced disclosures are also required to provide information about a vendor’s multiple-deliverable revenue arrangements, including information about the nature and terms, significant deliverables, and its performance within arrangements. The amendments also require providing information about the significant judgments made and changes to those judgments and about how the application of the relative selling-price method affects the timing or amount of revenue recognition. The amendments in this ASU were effective prospectively for revenue arrangements entered into or materially modified in the fiscal years beginning on or after June 15, 2010. We adopted the new ASU in the first quarter of 2011 and the adoption did not have a material impact on our financial position, results of operations, or cash flows.
     In October 2009, the FASB issued an ASU that changed the accounting model for revenue arrangements that include both tangible products and software elements that are “essential to the functionality,” and scoped these products out of current software revenue guidance. The new ASU includes factors to help companies determine what software elements are considered “essential to the functionality.” The amendments now subject software-enabled products to other revenue guidance and disclosure requirements, such as guidance surrounding revenue arrangements with multiple-deliverables. The amendments in this ASU were effective prospectively for revenue arrangements entered into or materially modified in the fiscal years beginning on or after June 15, 2010. We adopted the new ASU in the first quarter of 2011 and the adoption did not have a material impact on our financial position, results of operations, or cash flows.
     ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.
     Information concerning market risk is contained in the section entitled “Quantitative and Qualitative Disclosures About Market Risk” contained in our Annual Report on Form 10-K for the year ended December 31, 2010 filed with the Securities and Exchange Commission on February 25, 2011.

     ITEM 4. CONTROLS AND PROCEDURES.
     Evaluation of Disclosure Controls and Procedures
     Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2011. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), means controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of June 30, 2011, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms and is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer as appropriate to allow timely decisions regarding required disclosure.
     Changes in Internal Control over Financial Reporting
     There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended June 30, 2011 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
     PART II. OTHER INFORMATION
     ITEM 1. LEGAL PROCEEDINGS.
     We are subject to various legal proceedings and claims, which have arisen in the ordinary course of business.
     In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on our results of operations, financial condition or cash flows.
     ITEM 1A. RISK FACTORS.
     Information regarding risk factors affecting the Company’s business are discussed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010 in the section entitled “Risk Factors.” There have been no material changes from the risks disclosed therein.
