The accompanying notes are an integral part of the unaudited condensed consolidated financial statements.

The terms “MKS” and the “Company” refer to MKS Instruments, Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The interim financial data as of ~~September 30, 2017,~~March 31, 2018, and for the three ~~and nine~~ months ended ~~September 30, 2017 and 2016~~March 31, 2018 are unaudited; however, in the opinion of MKS, the interim data includes all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results for the interim periods. The condensed consolidated balance sheet presented as of December 31, ~~2016~~2017 has been derived from the consolidated audited financial statements as of that date. The unaudited condensed consolidated financial statements presented herein have been prepared in accordance with the instructions to Form10-Q and do not include all of the information and note disclosures required by United States generally accepted accounting principles (“U.S. GAAP”). The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the MKS Annual Report on Form10-K for the year ended December 31, ~~2016~~2017 filed with the Securities and Exchange Commission on ~~March 1, 2017.~~February 28, 2018.

The preparation of these unaudited condensed 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 unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On anon-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, warranty liabilities, pension liabilities, 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.

The Company has historically recorded the revenue and related cost of revenue for the sale of its spare parts within Products in its Statements of Operations for the Vacuum & Analysis segment. The Company has now determined that these items are better presented within revenue and related cost of revenue in Services in its Statements of Operations to align with the current manner in which the Company operates its services business, and has elected to reclassify these amounts in previously issued financial statements as shown below. This change in presentation has no impact on total revenue or total cost of revenue.

In ~~August 2017,~~March 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-05, “Income Taxes (Topic 740).” This standard is an amendment that adopts the language of Securities and Exchange Commission Staff Accounting Bulletin No. 118 (“SAB 118”) and aims to address certain circumstances that may arise for registrants in accounting for the income tax effects of the Tax Cuts and Jobs Act (the “Act”) and to address any uncertainty or diversity of views in practice regarding the application of Topic 740 in situations where a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting under Topic 740 for certain income tax effects of the Act for the reporting period in which the Act was enacted. The provisions of this ASU were applied to the Company’s December 31, 2017 financial statements. The Company recorded provisional amounts with respect to the Act under SAB 118 at December 31, 2017 and March 31, 2018 and needs to complete additional analysis and receive additional guidance from the Internal Revenue Service with respect to provisions of the Act that affect the Company before the provisional determinations become final. Until the Company completes its analysis and receives additional guidance, the Company is not able to determine if the impact of ASU 2018-05 is material to the Company’s consolidated financial statements in any period.

In February 2018, the FASB issued ASU 2018-02, “Income Statement – Reporting Comprehensive Income (Topic 220).” The amendments in this standard allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Act. The provisions of this ASU are effective for annual periods beginning after December 15, 2018, including interim periods within those fiscal years. The Company does not expect adoption of this ASU to have a material impact on the Company’s consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815).” This standard better aligns an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. The provisions of this ASU are effective for annual periods beginning after December 15, 2018, including interim periods within those fiscal years. The Company does not expect adoption of this ASU to have a material impact on the Company’s consolidated financial statements.

In May 2017, the FASB issued ASU2017-09, “Compensation-Stock Compensation (Topic 718)-Scope of Modification Accounting.” This standard provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. The provisions of this ASU are effective for annual periods beginning after December 15, 2017, including interim periods within those fiscal years. ~~Early adoption is permitted for any interim period for which financial statements have not yet been issued.~~ The Company ~~does not expect~~adopted this ASU during the three month period ended March 31, 2018. The adoption of this ASU todid not have a material impact on the Company’s consolidated financial statements.

In March 2017, the FASB issued ASU2017-07, “Compensation-Retirement Benefits (Topic 715)-Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” This standard requires that an employer disaggregate the service cost component from the other components of net benefit cost. This standard also provides explicit guidance on how to present the service cost component and the other components of the net benefit cost in the income statement and allows only the service cost component of net benefit cost to be eligible for capitalization. The provisions of this ASU are effective for annual periods beginning after December 31, 2017, including interim periods within those fiscal years. ~~Early adoption is permitted as of the beginning of an annual period for which financial statements (interim or annual) have not been issued or made available for issuance.~~ The Company ~~does not expect~~adopted this ASU during the three month period ended March 31, 2018. The adoption of this ASU todid not have a material impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued ASU~~2017-04,~~ “Intangibles-Goodwill and Other (Topic 350).” This standard simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of goodwill. The provisions of this ASU are effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company expects to adopt this new standard in 2017 when it performs its annual goodwill impairment test in the fourth quarter. The Company does not expect adoption of this ASU to have a material impact on the Company’s consolidated financial statements.

~~NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS – (continued)~~

~~In January 2017, the FASB issued ASU~~2017-01, “Business Combinations (Topic 805)-Clarifying the Definition of a Business.” This standard clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This standard also provides a more robust framework to use in determining when a set of assets and activities is a business. Because the current definition of a business is interpreted broadly and can be difficult to apply, stakeholders indicated that analyzing transactions is inefficient and costly and that the definition does not permit the use of reasonable judgment. The provisions of this ASU are effective for annual periods beginning after December 15, 2017, including interim periods within those fiscal years. ~~Early adoption is applicable under certain circumstances.~~ The Company ~~does not expect~~adopted this ASU during the three month period ended March 31, 2018. The adoption of this ASU todid not have a material impact on the Company’s consolidated financial statements.

In November 2016, the FASB issued ASU2016-18, “Statement of Cash Flows (Topic 230)-Restricted Cash,” an amendment to ASU2016-15. This standard requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash and restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling thebeginning-of-period andend-of-period total amounts shown on the statement of cash flows. ~~Early adoption is permitted.~~ The provisions of this ASU are effective for annual periods beginning after December 15, 2017, including interim periods within those fiscal years and should be applied at the time of adoption of ASU2016-15. The Company ~~does not expect~~adopted this ASU during the three month period ended March 31, 2018. The adoption of this ASU todid not have a material impact on the Company’s consolidated financial statements.

In October 2016, the FASB issued ASU2016-16, “Income Taxes (Topic 740)-Intra-Entity Transfer of Assets Other Than Inventory.” This standard requires that an entity recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs as opposed to when the assets have been sold to an outside party. The provisions of this ASU are effective for annual periods beginning after December 15, 2017, including interim periods within those fiscal ~~years and early adoption is permitted.~~years. The Company ~~does not expect~~adopted this ASU during the three month period ended March 31, 2018. The adoption of this ASU todid not have a material impact on the Company’s consolidated financial statements.

In August 2016, the FASB issued ASU2016-15, “Statement of Cash Flows (Topic 230)-Classification of Certain Cash Receipts and Cash Payments.” This standard addresses eight specific cash flow issues with the objective of addressing the diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230. The

In February 2016, the FASB issued ASU2016-02, “Leases (Topic 842).” This standard requires the recognition of lease assets and liabilities for all leases, with certain exceptions, on the balance sheet. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. This ASU is effective for annual periods beginning after December 15, 2018, including interim periods within those fiscal years.

In January 2016, the FASB issued ASU2016-01, “Financial Instruments-Overall (Subtopic825-10): ~~Recognition~~-Recognition and Measurement of Financial Assets and Financial Liabilities.” This ASU provides guidance for the recognition, measurement, presentation, and disclosure of financial instruments. The new ~~pronouncement~~standard revises accounting related to equity investments and the presentation of certain fair value changes for financial assets and liabilities measured at fair value. Among other things, it amends the presentation and disclosure requirements of equity securities that do not result in consolidation and are not accounted for under the equity method.

This ~~pronouncement~~standard is effective for annual periods beginning after December 15, 2017, including interim periods within those fiscal years. The Company ~~does not expect~~adopted this ASU during the three month period ended March 31, 2018.

In May 2014, the FASB issued ASU2014-09, “Revenue from Contracts with Customers (Topic 606).” (“ASC 606”). This ASU~~2014-09~~ provides for a single comprehensive model to use in accounting for revenue arising from contracts with customers and ~~will replace~~has replaced most existing revenue recognition guidance in ~~GAAP when it becomes effective.~~GAAP. This ASU~~2014-09~~ is effective for fiscal years and interim periods within those years beginning after December 15, 2017. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. The Company ~~does not plan to early adopt the standard, but has concluded that it will use~~used the modified retrospective method upon adoption in the first quarter of 2018. The FASB issued additional updates to the new revenue standard in Topic 606 relating to reporting revenue on a gross versus net basis (Update 2016-08 in March 2016), identifying performance obligations and licensing arrangements (Update 2016-10 in April 2016), narrow-scope improvements and practical expedients (Update 2016-12 in May 2016), technical corrections and improvements (Update 2016-20 in December 2016), and SEC Updates (Update 2017-13 in September 2017 and Update 2017-14 in November 2017). The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements as described further in Note 3.

The Company adopted ASC 606 on January 1, 2018 using the modified retrospective method for all contracts not completed as of the date of adoption. The reported results for the three months ended March 31, 2018 reflect the application of ASC 606 guidance while the reported results for 2017 were prepared under the guidance of ASC 605, Revenue Recognition (ASC 605).

The Company has recorded a net increase to opening retained earnings of $1,809 as of January 1, 2018 due to the cumulative impact of adopting ASC 606, with the impact primarily related to its service business and certain custom products. The impact to revenues for the quarter ended March 31, 2018 was immaterial as a result of applying ASC 606.

The adoption of ASC 606 represents a change in accounting principle that will more closely align revenue recognition with the delivery of the Company’s goods or services and will provide financial statement readers with enhanced disclosures. To achieve this core principle, the Company applies the following five steps:

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS ~~– (continued)~~

Revenue under ASC 606 is recognized when or as obligations under the terms of a contract with the Company’s customer have been satisfied and control has transferred to the customer. The majority of the Company’s performance obligations, and associated revenue, are transferred to customers at a point in time, generally upon shipment of a product to the customer or receipt of the product by the customer and without significant judgments. Installation services are not significant and are usually completed in a short period of time (normally less than two weeks) and therefore, recorded at a point in time when the installation services are completed, rather than over time as they are not material. Extended warranty, service contracts, and repair services, which are transferred to the customer over time, are recorded as revenue as the services are performed. For repair services, the Company makes an accrual at quarter end based upon historical repair times within its product groups to record revenue based upon the estimated number of days completed to date, which is consistent with ratable recognition. Customized products with no alternative future use to the Company, and that have an enforceable right to payment for performance completed to date, are also recorded over time. The Company considers this to be a faithful depiction of the transfer to the customer of revenue over time as the work or service is performed.

Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring goods or providing services. Performance obligations promised in a contract are identified based on the products or services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the product or service either on its own or together with other resources that are readily available from third parties or from the Company, and are distinct in the context of the contract, whereby the transfer of the product or service is separately identifiable from other promises in the contract. Sales, value add, and other taxes the Company collects concurrent with revenue-producing activities are excluded from revenue. The Company’s normal payment terms are 30 to 60 days but vary by the type and location of its customers and the products or services offered. The time between invoicing and when payment is due is not significant. For certain products or services and customer types, the Company requires payment before the products or services are delivered to the customer. None of the Company’s contracts as of March 31, 2018 contain a significant financing component. Contract assets as of January 1 and March 31, 2018 were immaterial and included in other current assets.

The Company periodically enters into contracts with its customers in which a customer may purchase a combination of goods and or services, such as products with installation services or extended warranty obligations. These contracts include multiple promises that the Company evaluates to determine if the promises are separate performance obligations. Once the Company determines the performance obligations, the Company then determines the transaction price, which includes estimating the amount of variable consideration to be included in the transaction price, if any. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing either the expected value method or the most likely amount method depending on the method the Company expects to better predict the amount of consideration to which it will be entitled. There are no constraints on the variable consideration recorded. The Company then allocates the transaction price to each performance obligation in the contract based on a relative stand-alone selling price charged separately to customers or using an expected cost-plus-margin method. The corresponding revenues are recognized when or as the related performance obligations are satisfied, which are noted above. The impact of variable consideration was immaterial during the three months ended March 31, 2018.

The Company’s standard assurance warranty period is normally 12 to 24 months. The Company sells separately-priced service contracts and extended warranty contracts related to certain of its products, especially its laser products. The separately priced contracts generally range from 12 to 60 months. The Company normally receives payment at the inception of the contract and recognizes revenue over the term of the agreement in proportion to the costs expected to be incurred in satisfying the obligations under the contract. The Company has elected to use the practical expedient related to disclosing the remaining performance obligations as of March 31, 2018, as the majority have a duration of less than one year.

In addition, the Company does not expect any major changes to be made to its existing accounting systems or internal controls.

Management has the ability, if necessary, to liquidate any of its investments in order to meet the Company’s liquidity needs in the next 12 months. Accordingly, those investments with contractual maturities greater than one year from the date of purchase are classified as short-term on the accompanying balance sheets.

The Company reviews and evaluates its investments for any indication of possible impairment. Based on this review, the Company has determined that the unrealized losses related to these investments at ~~September 30, 2017~~March 31, 2018 and December 31, 2017, were temporary.

Interest income is accrued as earned. Dividend income is recognized as income on the date the stock trades~~“ex-dividend.~~ “ex-dividend.” The cost of marketable securities sold is determined by the specific identification method. Realized gains or losses are reflected in income and were not material for the three ~~and nine~~ months ended ~~September 30, 2017~~March 31, 2018 and ~~2016.~~2017.

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:

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the Company categorizes such assets and liabilities based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s 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 or liability.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS ~~– (continued)~~

Money market funds are cash and cash equivalents and are classified within Level 1 of the fair value hierarchy.

The Company has letters of credit, which require it to maintain specified cash deposit balances, consisting mainly of money market funds, as collateral. Such amounts have been classified as restricted cash and are classified as Level 1.

Available-for-sale investments consisted of time deposits and drafts, certificates of deposit, bankers acceptance drafts, asset-backed securities (which include auto loans, credit card receivables and equipment trust receivables), commercial paper, corporate obligations, municipal bonds, ~~promissory notes,~~ U.S. treasury obligations and U.S. agency obligations.

The Company measures its debt and equity investments at fair value. The Company’savailable-for-sale investments are classified within Level 2 of the fair value hierarchy.

Israeli pension assets represent investments in mutual funds, government securities and other time deposits. These investments are set aside for the retirement benefit of the employees at the Company’s Israeli subsidiaries. These funds are classified within Level 2 of the fair value hierarchy.

As a result of the Company’s global operating activities, the Company is exposed to market risks from changes in foreign currency exchange rates and variable interest rates, which may adversely affect its operating results and financial position. When deemed appropriate, the Company minimizes its risks from foreign currency exchange rate and interest rate fluctuations through the use of derivative financial instruments. The principal market in which the Company executes its foreign currency contracts and interest rate swaps is the institutional market in anover-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 and interest rate hedge are valued using broker quotations or market transactions and are classified within Level 2 of the fair value hierarchy.

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 foreign currency exchange contracts, to manage certain foreign currency exposure, and interest rate swaps to manage interest rate exposure.

By nature, all financial instruments involve market and credit risks. The Company enters into derivative instruments with major investment grade financial institutions, for which 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 materialnon-performance by any of these counterparties.

On September 30, 2016, the Company entered into an interest rate swap agreement to fix the rate on approximately 50% of its then-outstanding balance under the Credit Agreement, as described further in Note 9.10. This hedge fixes the interest rate paid on the hedged debt at 1.198% per annum plus the applicable credit spread, which was ~~2.25%~~2.00% as of ~~September 30, 2017,~~March 31, 2018, through September 30, 2020. The interest rate swap is recorded at fair value on the balance sheet and changes in the fair value are recognized in other comprehensive income (loss) (“OCI”). To the extent that this arrangement is no longer an effective hedge, any ineffectiveness measured in the hedging relationship is recorded currently in earnings in the period it occurs. The notional amount of this transaction was $305,000 and had a fair value of ~~$4,362~~$8,170 at ~~September 30,~~March 31, 2018. The notional amount of this transaction was $305,000 and had a fair value of $6,179 at December 31, 2017.

~~NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS – (continued)~~

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, Euro and Taiwanese currencies. To the extent these derivatives are effective inoff-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 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.

As of ~~September 30, 2017~~March 31, 2018 and December 31, ~~2016,~~2017, the Company had outstanding forward foreign exchange contracts with gross notional values of ~~$86,217~~$228,463 and ~~$120,208,~~$208,922, respectively.

On April 29, 2016, the Company completed its acquisition of Newport Corporation (“Newport”) pursuant to an Agreement and Plan of Merger, dated as of February 22, 2016 (the “Merger Agreement”), by and among the Company, PSI Equipment, Inc., a wholly owned subsidiary of the Company (“Merger Sub”), and Newport (the “Newport Merger”). At the effective time of the Newport Merger and pursuant to the terms and conditions of the Merger Agreement, each share of Newport’s common stock that was issued and outstanding immediately prior to the effective time of the Newport Merger was converted into the right to receive $23.00 in cash, without interest and subject to deduction for any required withholding tax.

~~Newport’s innovative solutions leverage its expertise in advanced technologies, including lasers, photonics and precision motion equipment, and optical components andsub-systems,~~ to enhance the capabilities and productivity of its customers’ manufacturing, engineering and research applications. Newport is a global supplier of advanced-technology products and systems to customers in the scientific research and defense/security, microelectronics, life and health sciences and industrial manufacturing markets.

~~NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS – (continued)~~

The Company funded the payment of the aggregate consideration with a combination of the Company’s available cash on hand and the proceeds from the Company’s senior secured Term Loan Facility, as described in Note 9.

Under the acquisition method of accounting, the total acquisition consideration is allocated to the acquired tangible and intangible assets and assumed liabilities of Newport based on their fair values as of the acquisition date. Any excess of the acquisition consideration over the fair value of assets acquired and liabilities assumed is allocated to goodwill. The Company concluded that all such goodwill and intangible assets will not be deductible for tax purposes.

~~The following table summarizes the allocation of the purchase price to the fair values assigned to assets acquired and liabilities assumed at the date of the Newport Merger:~~

~~The fair valuewrite-up~~ of acquired finished goods inventory was $15,090, the amount of which will be amortized over the expected period during which the acquired inventory is sold. Accordingly, the Company recorded incremental costs of sales charges associated with the fair value~~write-up~~ ~~of inventory acquired in the merger with Newport of $4,971 and $15,090 for the three and nine months ended September 30, 2016, respectively.~~

~~The fair valuewrite-up~~ ~~of acquired property, plant and equipment of $36,242 will be amortized over the useful life of the assets. Property, plant and equipment is valued at itsvalue-in-use,~~ ~~unless there was a known plan to dispose of the asset.~~

~~The acquired intangible assets are being amortized on a straight-line basis, which approximates the economic use of the asset.~~

~~NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS – (continued)~~

~~The following table reflects the allocation of the acquired intangible assets and liabilities and related estimate of useful lives:~~

The fair value of the acquired intangibles was determined using the income approach. In performing these valuations, the key underlying probability-adjusted assumptions of the discounted cash flows were projected revenues, gross margin expectations and operating cost estimates. The valuations were based on the information that was available as of the acquisition date and the expectations and assumptions that have been deemed reasonable by the Company’s management. There are inherent uncertainties and management judgment required in these determinations. This acquisition resulted in a purchase price that exceeded the estimated fair value of tangible and intangible assets, the excess amount of which was allocated to goodwill.

The Company believes the amount of goodwill relative to identifiable intangible assets relates to several factors including: (1) potential buyer-specific synergies related to market opportunities for a combined product offering; and (2) potential to leverage the Company’s sales force to attract new customers and revenue and cross sell to existing customers.

~~The results of this acquisition were included in the Company’s consolidated operations beginning on April 29, 2016. Newport constitutes the Company’s Light & Motion reportable segment (Note 16).~~

Certain executives from Newport had severance provisions in their respective Newport employment agreements. The agreements included terms that were accounted for as dual-trigger arrangements. Through the Company’s acquisition accounting, the expense relating to these benefits was recognized in the combined entity’s financial statements, however, the benefit itself will not be distributed until the final provision is met by each eligible executive. The Company recorded costs of $6,631 and $3,334 as compensation expense and stock-based compensation expense, respectively, for the three and nine months ended September 30, 2016, respectively, in connection with these severance provisions. The shares underlying the restricted stock units and stock appreciation rights that are eligible for accelerated vesting if the executive exercises his rights are not issued as of each reporting~~period-end~~ ~~and are excluded from the computation of basic earnings per share and included in the computation of diluted earnings per share for each reporting period.~~

~~The following unauditedpro-forma~~ ~~financial information presents the combined results of operations of the Company as if the acquisition of Newport had occurred on January 1, 2015. The unauditedpro-forma~~ financial information is not necessarily indicative of what the Company’s consolidated results of operations actually would have been had the acquisition occurred at the beginning of each year. In addition, the unaudited~~pro-forma~~ ~~financial information does not attempt to project the future results of operations of the combined company.~~

~~NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS – (continued)~~

~~The unauditedpro-forma~~ ~~financial information above gives effect primarily to the following:~~

In April 2016, the Company invested $9,300 for a minority interest in a private company, which operates in the field of semiconductor process equipment instrumentation. The Company accounted for this investment using the cost method of accounting. During the fourth quarter of 2016, the Company recognized an impairment loss on this investment of $5,000 based upon financial information of this private company. In July 2017, the Company invested an additional $100 in this private company.

In April 2017, the Company completed the sale of its Data Analytics Solutions business for total proceeds of $72,509, net of cash sold and recorded a gain of $74,856. This business, which had revenues in 2016 of $12,700 and was included in the Vacuum & Analysis segment, was no longer a part of the Company’s long-term strategic objectives.

The business did not qualify as a discontinued operation as this sale did not represent a strategic shift in the Company’s business, nor did the sale have a major effect on the Company’s operations. Therefore, the results of operations for all periods are included in the Company’s income from operations. The assets and liabilities of this business have not been reclassified or segregated in the consolidated balance sheet or consolidated statements of cash flows as the amounts were immaterial.

The Company’s methodology for allocating the purchase price relating to purchase acquisitions is determined through established and generally accepted valuation techniques. Goodwill is measured as the excess of the cost of the acquisition over the sum of the amounts assigned to tangible and identifiable intangible assets acquired less liabilities assumed. The Company assigns assets acquired (including goodwill) and liabilities assumed to one or more reporting units as of the date of acquisition. Typically acquisitions relate to a single reporting unit and thus do not require the allocation of goodwill to multiple reporting units. If the products obtained in an acquisition are assigned to multiple reporting units, the goodwill is distributed to the respective reporting units as part of the purchase price allocation process.

Goodwill and purchased intangible assets with indefinite useful lives are not amortized, but are reviewed for impairment annually during the fourth quarter of each fiscal year and whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. The process of evaluating the potential impairment of goodwill and intangible assets requires significant judgment. The Company regularly monitors current business conditions and other factors including, but not limited to, adverse industry or economic trends, restructuring actions and lower projections of profitability that may impact future operating results.

In connection with the completion of the Company’s acquisition of Newport ~~Merger,~~Corporation (“Newport”) in April 2016 (the “Newport Merger”), the Company entered into a term loan credit agreement (the “Credit Agreement”) with Barclays Bank PLC, as administrative agent and collateral agent, and the lenders from time to time party thereto (the “Lenders”), that provided senior secured financing of $780,000, subject to increase at the Company’s option in accordance with the Credit Agreement (the “Term Loan Facility”). Borrowings under the Term Loan Facility bear interest per annum at one of the following rates selected by the Company: (a) a base rate determined by reference to the highest of (1) the federal funds effective rate plus 0.50%, (2) the “prime rate” quoted in The Wall Street Journal, (3) a LIBOR rate determined by reference to the costs of funds for U.S. dollar deposits for an interest period of one month adjusted for certain additional costs, plus 1.00%, and (4) a floor of 1.75%, plus, in each case, an applicable ~~margin (that was initially 3.00% and was decreased as described below);~~margin; or (b) a LIBOR rate determined by reference to the costs of funds for U.S. dollar deposits for the interest period relevant to such borrowing adjusted for certain additional costs, subject to a LIBOR rate floor of 0.75%, plus an applicable ~~margin (that was initially 4.00% and was decreased as described below).~~margin. The Company has elected the interest rate as described in clause (b). The Credit Agreement provides that all loans will be determined by reference to the Base Rate if the LIBOR rate cannot be ascertained, if regulators impose material restrictions on the authority of a lender to make LIBOR rate loans, or for other reasons. The Term Loan Facility was issued with original issue discount of 1.00% of the principal amount thereof.

On June 9, 2016, the Company entered into Amendment No. 1 (the~~“Re-pricing~~ “Repricing Amendment 1”) to the Credit Agreement by and among the Company, the Lenders and Barclays Bank PLC, as administrative agent and collateral agent for the Lenders. The~~Re-pricing~~ Repricing Amendment 1 decreased the applicable margin for borrowings under the Company’s Term Loan Facility to 2.50% for base rate borrowings and 3.50% for LIBOR borrowings and extended the period during which a~~pre-payment~~ prepayment premium may be required for a~~“Re-pricing~~ “Repricing Transaction” (as defined in the Credit Agreement) until six months after the effective date of the~~Re-pricing~~ Repricing Amendment 1. In connection with the execution of the~~Re-pricing~~ Repricing Amendment 1, the Company paid a~~pre-payment~~ prepayment premium of 1.00%, or $7,300, as well as certain fees and expenses of the administrative agent and the Lenders, in accordance with the terms of the Credit Agreement. Immediately prior to the effectiveness of the~~Re-pricing~~ Repricing Amendment 1, the Company prepaid $50,000 of principal under the Credit Agreement. In September 2016, the Company prepaid an additional $60,000 under the Credit Agreement.

On September 30, 2016, the Company entered into an interest rate swap agreement, which has a maturity date of September 30, 2020, to fix the rate on $335,000 of the then-outstanding balance of the Credit Agreement.

Under the Credit Agreement, the Company is required to prepay outstanding term loans, subject to certain exceptions, with portions of its annual excess cash flow as well as with the net cash proceeds of certain asset sales, certain casualty and condemnation events and the incurrence or issuance of certain debt. The Company is also required to make scheduled quarterly payments each equal to 0.25% of the principal amount of the term loans outstanding, ~~on December 14, 2016 (the date of theRe-pricing~~ ~~Amendment 2)~~ less the amount of certain voluntary and mandatory repayments after such date, with the balance due on the seventh anniversary of the closing date. As a result of making total ~~pre-payments~~prepayments of ~~$325,000, as of September 30, 2017~~$425,000 through March 31, 2018, the Company is no longer required to make any scheduled principal payments until maturity date of the loan.

All obligations under the Term Loan Facility are guaranteed by certain of the Company’s domestic subsidiaries, and are collateralized by substantially all of the Company’s assets and the assets of such subsidiaries, subject to certain exceptions and exclusions.

The Credit Agreement contains customary representations and warranties, affirmative and negative covenants and provisions relating to events of default. If an event of default occurs, the Lenders under the Term Loan Facility will be entitled to take various actions, including the acceleration of amounts due under the Term Loan Facility and all actions generally permitted to be taken by a secured creditor. At ~~September 30, 2017,~~March 31, 2018, the Company was in compliance with all covenants under the Credit Agreement.

In connection with the completion of the Newport Merger, the Company also entered into an asset-based credit agreement with Deutsche Bank AG New York Branch, as administrative agent and collateral agent, the other borrowers from time to time party thereto, and the lenders and letters of credit issuers from time to time party thereto (the “ABL Facility”), that provides senior secured financing of up to $50,000, subject to a borrowing base limitation. The borrowing base for the ABL Facility at any time equals the sum of: (a) 85% of certain eligible accounts; plus (b) subject to certain notice and field examination and appraisal requirements, the lesser of (i) the lesser of (A) 65% of the lower of cost or market value of certain eligible inventory and (B) 85% of the net orderly liquidation value of certain eligible inventory and (ii) 30% of the borrowing base; minus (c) reserves established by the administrative agent; provided that until the administrative agent’s receipt of a field examination of accounts receivable the borrowing base shall be equal to 70% of the book value of certain eligible accounts. The ABL Facility includes borrowing capacity in the form of letters of credit up to $15,000. The Company has not drawn against the ABL Facility as of ~~September 30, 2017.~~March 31, 2018.

Borrowings under the ABL Facility bear interest per annum at one of the following rates selected by the Company: (a) a base rate determined by reference to the highest of (1) the federal funds effective rate plus 0.50%, (2) the “prime rate” quoted in The Wall Street Journal, and (3) a LIBOR rate determined by reference to the costs of funds for U.S. dollar deposits for an interest period of one month adjusted for certain additional costs, plus 1.00%, plus, in each case, an initial applicable margin of 0.75%; and (b) a LIBOR rate determined by reference to the costs of funds for U.S. dollar deposits for the interest period relevant to such borrowing

adjusted for certain additional costs, plus an initial applicable margin of 1.75%. Commencing with the completion of the first fiscal quarter ending after the closing of the ABL Facility, the applicable margin for borrowings thereunder is subject to upward or downward adjustment each fiscal quarter, based on the average historical excess availability during the preceding quarter.

~~NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS – (continued)~~

The Company incurred $1,201 of costs in connection with the ABL Facility, which were capitalized and included in other assets in the accompanying consolidated balance sheets and ~~will be~~are being amortized to interest expense using the straight-line method over the contractual term of five years of the ABL Facility.

In addition to paying interest on outstanding principal under the ABL Facility, the Company is required to pay a commitment fee in respect of the unutilized commitments thereunder. The initial commitment fee is 0.375% per annum. The total commitment fee recognized in interest expense for the ~~nine~~three months ended ~~September 30, 2017,~~March 31, 2018, was ~~$242.~~$95. Commencing with the completion of the first fiscal quarter ending after the closing of the ABL Facility, the commitment fee is subject to downward adjustment based on the amount of average unutilized commitments for the three month period immediately preceding such adjustment date. The Company must also pay customary letter of credit fees and agency fees.

One of the Company’s Japanese subsidiaries has lines of credit and short-term borrowing arrangements with two financial institutions, which arrangements generally expire and are renewed at three month intervals. The lines of credit provided for aggregate borrowings as of ~~September 30, 2017~~March 31, 2018 of up to an equivalent of ~~$20,444~~$21,641 U.S. dollars. One of the borrowing arrangements has an interest rate based on the Tokyo Interbank Offer Rate at the time of borrowing and the other has an interest rate based on the Japanese Short-Term Prime Lending Rate. Total borrowings outstanding under these arrangements were $941 at March 31, 2018. There were no borrowings outstanding under these arrangements at ~~September 30, 2017 and~~ December 31, ~~2016.~~2017.

The Company assumed various revolving lines of credit and a financing facility with the completion of the Newport Merger. These revolving lines of credit and financing facility have no expiration date and provided for aggregate borrowings as of ~~September 30, 2017~~March 31, 2018 of up to an equivalent of ~~$11,111~~$9,879 U.S. dollars. These lines of credit have a base interest rate of 1.25% plus a Japanese Yen overnight LIBOR rate. Total borrowings outstanding under these arrangements were $3,828 and $2,965 at March 31, 2018 and December 31, 2017.

One of the Company’s Austrian subsidiaries has ~~four~~various outstanding loans from the Austrian government to fund research and development. These loans are unsecured and do not require principal repayment as long as certain conditions are met. Interest on these loans is payable semi-annually. The interest rates associated with these loans range from 0.75% -to 2.00%.

The Company records 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 Act was enacted on December 22, 2017. The Act reduces the U.S. federal corporate income tax rate from 35% to 21%, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred, and creates new taxes on certain foreign sourced earnings. The Company is applying SAB 118 when accounting for the enactment effects of the Act. As of March 31, 2018, the Company has not completed the accounting for all of the tax effects of the Act, however provisional estimates have been recorded.

For the quarter ended March 31, 2018, the Company recognized a tax benefit of $790 related to the provisional estimates recorded for the Act and included these adjustments as a component of income tax expense from continuing operations. The calculations will continue to be refined and adjusted as additional analysis is completed and more guidance is issued. These future adjustments could be material to income tax expense.

The global intangible low-taxed income (“GILTI”) provision from the Act subjects a U.S. shareholder to current tax on GILTI earned by certain foreign subsidiaries. The FASB Staff Q&A, Topic 740 No. 5, Accounting for Global Intangible Low-Taxed Income, states that an entity can make an accounting policy election to either recognize deferred taxes for temporary differences expected to reverse as GILTI in future years or to recognize the resulting tax on GILTI as a period expense in the period the tax is incurred. The Company has elected to recognize the resulting tax on GILTI as a period expense in the period the tax is incurred and expects to incur tax for the year ended December 31, 2018. The reasonable estimate for this adjustment, net of foreign tax credits, increased the Company’s effective tax rate for 2018 by approximately 1.0%.

The Company’s effective tax rate for the three ~~and nine~~ months ended ~~September 30,~~March 31, 2018 and 2017 was ~~25.0%~~17.1% and ~~22.3%~~15.8%, respectively. The effective tax rate for the three ~~and nine~~ months ended ~~September 30, 2017~~March 31, 2018, and related income tax expense, was lower than the U.S. statutory tax rate mainly due to the geographic mix of income earned by the Company’s international subsidiaries being taxed at rates lower than the U.S. statutory tax rate, windfall benefits of stock compensation, and the new deduction for foreign derived intangible income

from the Act offset by the tax ~~benefit~~effects of ~~windfall stock compensation deductions and~~ the ~~deduction~~new provision for ~~domestic production activities. These amounts were partially offset by taxes accrued, net of foreign tax credits, on actual and planned distributions~~global intangible low taxed income from the ~~Company’s international subsidiaries. The Company’s effective tax rate for the three~~Act and ~~nine months ended September 30, 2016 was 23.0% and 24.4%, respectively.~~ state income taxes.

The effective tax rate for the three ~~and nine~~ months ended ~~September 30, 2016~~March 31, 2017 was lower than the U.S. statutory tax rate ~~primarily~~mainly due to the ~~geographic mix~~impact of ~~income and profits earned by the Company’s international subsidiaries being taxed at~~lower tax rates ~~lower than the U.S. statutory tax rate, the federal research credit and~~on foreign income, the deduction for domestic production ~~activities. These amounts were partially offset by taxes paid in connection with the Company’s reorganization~~activities and windfall benefits of ~~certain international subsidiaries and state income taxes.~~stock compensation.

As of ~~September 30,~~March 31, 2018 and December 31, 2017, the total amount of gross unrecognized tax benefits, which excludes interest and penalties, was approximately ~~$26,571. At December 31, 2016 the total amount of gross unrecognized tax benefits, which excludes interest~~$27,938 and ~~penalties, was approximately $25,465.~~$27,345, respectively. As of ~~September 30, 2017, there~~March 31, 2018, if these benefits were ~~$18,091~~recognized in a future period, the timing of which is not estimable, the net unrecognized tax ~~benefits,~~benefit of $20,525, excluding interest and penalties, ~~that, if recognized,~~ 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. As of ~~September 30, 2017~~March 31, 2018 and December 31, ~~2016,~~2017, the Company had accrued interest on unrecognized tax benefits of approximately ~~$367~~$532 and ~~$491,~~$327, respectively.

Over the next 12 months it is reasonably possible that the Company may recognize approximately ~~$1,733~~$1,047 of previously net unrecognized tax benefits, excluding interest and penalties, related to various U.S. federal, state and foreign tax positions primarily as a result of the expiration of certain statutes of limitations.

The Company and its subsidiaries are subject to examination by U.S. federal, state and foreign tax authorities. The United States Internal Revenue Service commenced an examination of the Company’s U.S. federal income tax ~~filing~~filings for ~~the~~tax years 2015 ~~tax year~~and 2016 during the quarter ended September 30, 2017. This audit was effectively settled during the quarter ended March 31, 2018, and the impact was not material. Also during the quarter, the Company received notification from the United States Internal Revenue Service that a new audit is scheduled to begin for its U.S. subsidiary, Newport Corporation, for tax year 2015. The U.S. statute of limitations remains open for tax years 2014 through present. The statute of limitations for the Company’s tax filings in other jurisdictions varies between fiscal years 2012 through present. ~~The Company~~We also ~~has~~have certain federal credit carry-forwards and state tax loss and credit carry-forwards that are open to examination for tax years 2000 through the present.

As a result of the acquisition of Newport, the Company has assumed all assets and liabilities of Newport’s defined benefit pension plans, which ~~cover~~covers substantially all of its full-time employees in France, Germany, Israel and Japan. In addition, there are certain pension liabilities relating to former employees in the United Kingdom. The German plan is unfunded, as permitted under the plan and applicable laws. The net periodic benefit costs were ~~approximately $254 and $761,~~immaterial for both the three ~~and nine~~ month periods ended ~~September 30, 2017, respectively,~~March 31, 2018 and ~~approximately $673 and $1,126 for the three and nine month periods ended September 30, 2016, respectively.~~2017.

The following table sets forth the computation of basic and diluted net income per share:

Diluted	$	1.38	$	0.60	$	4.75	$	1.10	$	1.90	$	1.18

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~~

(using the treasury stock method) if securities containing potentially dilutive common shares (restricted stock units and stock appreciation rights) had been converted to such common shares, and if such assumed conversion is dilutive.

For the three ~~and nine~~ months ended ~~September 30, 2017,~~March 31, 2018, there were approximately ~~200 and 300~~380 weighted-average restricted stock units ~~respectively,~~and no weighted-average stock appreciation rights, that would have had an anti-dilutive effect on EPS, and would thus need to be excluded from the computation of diluted weighted-average shares. For the three ~~and nine~~ months ended ~~September 30, 2016,~~March 31, 2017, there were ~~0 and approximately 500~~no weighted-average shares of restricted stock units ~~respectively,~~or stock appreciation rights that would have had an anti-dilutive effect on EPS, and would thus need to be excluded from the computation of diluted weighted-average shares.

On July 25, 2011, the Company’s Board of Directors approved a share repurchase program for the repurchase of up to an aggregate of $200,000 of its outstanding 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. The Company has repurchased approximately 1,770,000 shares of common stock for approximately $52,000 pursuant to the program since its adoption.

Future dividend declarations, if any, as well as the record and payment dates for such dividends, are subject to the final determination of the Company’s Board of Directors. In addition, under the terms of the Company’s senior secured Term Loan Facility and its senior secured asset-based revolving credit facility, the Company may be restricted from paying dividends under certain circumstances.

The Company has granted Restricted Stock Units (“RSUs”) to employees and directors under the 2014 Stock Incentive Plan (the “2014 Plan”). The 2014 Plan is administered by the Compensation Committee of the Company’s Board of Directors. The 2014 Plan is intended to attract and retain employees and directors, and to provide an incentive for these individuals to assist the Company to achieve long-range performance goals and to enable these individuals to participate in the long-term growth of the Company.

As of the effective time of the Newport Merger, based on a formula provided in the Merger Agreement, (a) the Newport RSUs were converted automatically into RSUs with respect to 360,674 shares of the Company’s common stock (the “Assumed RSUs”), and (b) the Newport stock appreciation rights were converted automatically into stock appreciation rights with respect to 899,851 shares of the Company’s common stock (the “Assumed SARs”).

Included in the total number of Assumed RSUs were 36,599 RSUs for outside directors that were part of the Newport Deferred Compensation Plan (the “DC Plan”), from which 19,137 underlying shares were released in May 2016, and 5,515 underlying shares were released in May 2017. Combined with an additional 286 shares that were added to the DC Plan due to reinvested dividends as of September 30, 2017, 12,233 RSUs remain outstanding under the DC Plan. These Assumed RSUs will not become issued shares until their respective release dates.

~~The shares of the Company’s common stock that are subject to the Assumed SARs and the Assumed RSUs are issuable pursuant to the Company’s 2014 Stock Incentive Plan (the “Plan”).~~

The 1,260,525 shares of the Company’s common stock that are issuable pursuant to the Assumed RSUs and the Assumed SARs under the Plan were registered under the Securities Act of 1933, as amended (the “Securities Act”), on a registration statement on Form~~S-8.~~ These shares are in addition to the 18,000,000 shares of the Company’s common stock reserved for issuance under the Plan and previously registered under the Securities Act on a registration statement on Form~~S-8.~~

During the ~~nine~~three months ended ~~September 30, 2017,~~March 31, 2018, the Company granted ~~388,137~~122,831 RSUs with a weighted average grant date fair value of ~~$67.58.~~$109.62. During the three months ended March 31, 2017, the Company granted 171,179 RSUs with a weighted average grant date fair value of $66.06. There were no SARs granted during the ~~nine~~three months ended ~~September 30,~~March 31, 2018 or 2017.

The future compensation expense is recognized on a straight-line basis over the requisite service period, net of estimated forfeitures except for retirement eligible employees in which the Company expenses the fair value of the grant in the period the grant is issued. The Company considers many factors when estimating expected forfeitures, including types of awards and historical experience. Actual results and future changes in estimates may differ substantially from the Company’s current estimates.

At September 30, 2017 the Company’s outstanding and exercisable SARs, the weighted-average base value, the weighted average remaining contractual life and the aggregate intrinsic value thereof, were as follows:

The Company is a global provider of instruments, subsystems and process control solutions that measure, ~~control,~~monitor, deliver, analyze, power ~~monitor~~ and ~~analyze~~control critical parameters of advanced manufacturing processes to improve process performance and productivity. The Company’s products are derived from its core competencies in pressure measurement and control, flow measurement and control, gas and vapor delivery, gas composition analysis, residual gas analysis, leak detection, control technology, ozone generation and delivery, RF & DC power, reactive gas generation, vacuum technology, lasers, photonics,sub-micron positioning, vibration ~~isolation,~~control, and optics. The Company also provides services related to the maintenance and repair of its products, installation services and training.

The Company’s Chief Operating Decision Maker (“CODM”) utilizes financial information to make decisions about allocating resources and assessing performance for the entire Company, which is used in the decision making process to assess performance. Based upon the information provided to the CODM, the Company has determined it has two reportable segments.

~~NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS – (continued)~~

Effective April 29, 2016, in conjunction with the Newport Merger, the Company changed its reportable segments based upon the organizational structure of the Company and how the CODM utilizes information provided to allocate resources and make decisions. The Company’s two reportable segments are: Vacuum & Analysis and Light & Motion. ~~The Vacuum & Analysis segment represents the legacy MKS business and the Light & Motion segment represents the legacy Newport business.~~

The Vacuum & Analysis segment provides a broad range of instruments, components and subsystems which are derived from the Company’s core competencies in pressure measurement and control, flow measurement and control, gas and vapor delivery, gas composition analysis, residual gas analysis, leak detection, control technology, ozone generation and delivery, RF & DC power, reactive gas generation and vacuum technology.

The Light & Motion segment provides a broad range of instruments, components and subsystems which are derived from the Company’s core competencies in lasers, photonics,sub-micron positioning, vibration ~~isolation,~~control, and optics.

The Company derives its segment results directly from the manner in which results are reported in its management reporting system.

~~The activity related to the Company’s restructuring accrual is shown below:~~Restructuring activities were as follows:

On March 9, 2016, a putative class action lawsuit captionedDixon Chung v. Newport Corp., et al.,, Case No.A-16-733154-C, was filed in the District Court, Clark County, Nevada on behalf of a putative class of stockholders of Newport for claims related to the

Merger Agreement between the Company, Newport, and Merger Sub. The complaint, filed on March 9, 2016, named as defendants the Company, Newport and Merger Sub, and certain then-current and former members of Newport’s former board of directors. The complaint alleges that the named directors breached their fiduciary duties to Newport’s stockholders by agreeing to sell Newport through an inadequate and unfair process, which led to inadequate and unfair consideration, and by agreeing to unfair deal protection devices. The complaint also alleges that the Company, Newport, and Merger Sub aided and abetted the named directors’ alleged breaches of their fiduciary duties. The complaint seeks injunctive relief, including to enjoin or rescind the Merger Agreement, monetary damages, and an award of attorneys’ and other fees and costs, among other relief. On March 25, 2016, the plaintiff in the Chung action filed an amended complaint, which adds certain allegations, including that the preliminary proxy statement filed by Newport on March 15, 2016 (the “Proxy”) omitted material information. The amended complaint also names as defendants the Company, Newport, Merger Sub, and then-current members of Newport’s board of directors.

~~Also on~~ March 25, 2016, a second putative class action complaint captionedHubert C. Pincon v. Newport Corp., et al., Case No.A-16-734039-B, was filed in the District Court, Clark County, Nevada, on behalf of a putative class of Newport’s stockholders for claims related to the Merger Agreement.

On April 14, 2016, the Court granted plaintiffs’ motion to consolidate the Pincon and Chung actions and appointed counsel in the Pincon action as lead counsel. Also on April 14, 2016, the Court granted plaintiffs’ motion for expedited discovery and scheduled a hearing on plaintiffs’ anticipated motion for a preliminary injunction for April 25, 2016. On April 20, 2016, plaintiffs filed a motion to vacate the hearing on their anticipated motion for a preliminary injunction and notified the Court that they did not presently intend to file a motion for a preliminary injunction regarding the Merger Agreement. On April 22, 2016, the Court vacated the hearing on plaintiffs’ anticipated motion for a preliminary injunction. In August 2016, plaintiffs completed the expedited discovery that the Court ordered.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

This Quarterly Report on Form10-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 of 1934, as amended (the “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 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 Form10-K for the year ended December 31, ~~2016~~2017 in the section entitled “Risk Factors” as referenced in Part II, Item 1A “Risk Factors” of this Quarterly Report on Form10-Q.

We are a global provider of instruments, subsystems and process control solutions that measure, ~~control,~~monitor, deliver, analyze, power ~~monitor~~ and ~~analyze~~control critical parameters of advanced manufacturing processes to improve process performance and productivity. Our products are derived from our core competencies in pressure measurement and control, flow measurement and control, gas and vapor delivery, gas composition analysis, residual gas analysis, leak detection, control technology, ozone generation and delivery, RF & DC power, reactive gas generation, vacuum technology, lasers, photonics,sub-micron positioning, vibration ~~isolation,~~control, and optics. We also provide services ~~related~~relating to the maintenance and repair of our products, installation services and training.

~~Our primary served markets include semiconductor capital equipment, general industrial, life sciences, and research.~~

On April 29, 2016, we completed our acquisition of Newport Corporation (“Newport”) pursuant to an Agreement and Plan of Merger dated as of February 22, 2016 (the “Newport Merger”). At the effective time of the Newport Merger, each share of Newport’s common stock issued and outstanding as of immediately prior to the effective time of the Newport Merger was converted into the right to receive $23.00 in cash, without interest and subject to deduction for any required withholding tax. We paid to the former Newport stockholders aggregate consideration of $905 million, excluding related transaction fees and expenses, and repaid $93 million of Newport’s U.S. indebtedness outstanding as of immediately prior to the effective time of the Newport Merger. We funded the payment of the aggregate consideration with a combination of our available cash on hand of $240 million and the proceeds from the senior secured Term Loan Facility of $780 million described below.

Newport is a global supplier of advanced-technology products and systems to customers in the scientific research and defense/security, microelectronics, life and health sciences and industrial manufacturing markets.

Effective April 29, 2016, in conjunction with our acquisition of Newport, we changed the structure of our reportable segments based upon our organizational structure and how our Chief Operating Decision Maker utilizes information provided to allocate resources and make decisions. Our two reportable segments are the Vacuum & Analysis segment and the Light & Motion segment. ~~The Vacuum & Analysis segment represents the legacy MKS business and the Light & Motion segment represents the legacy Newport business.~~

The Vacuum & Analysis segment provides a broad range of instruments, components and subsystems which are derived from our core competencies in pressure measurement and control, flow measurement and control, gas and vapor delivery, gas composition analysis, residual gas analysis, leak detection, control technology, ozone generation and delivery, RF & DC power, reactive gas generation and vacuum technology. The Light & Motion segment provides a broad range of instruments, components and subsystems which are derived from our core competencies in lasers, photonics,sub-micron positioning, vibration ~~isolation~~control, and optics.

Our primary served markets are manufacturers of capital equipment for semiconductor manufacturing, industrial technologies, life and health sciences, as well as research and defense. We have a diverse base of customers. Approximately ~~60% and 58% of~~57% our net revenues for both the ~~nine~~three months ended ~~September 30,~~March 31, 2018 and 2017, ~~and 2016, respectively,~~ were from sales to semiconductor capital equipment manufacturers and semiconductor device manufacturers.

Approximately ~~40% and 42%~~43% of our net revenues for ~~the nine~~both three months ended ~~September 30,~~March 31, 2018 and 2017, ~~and 2016, respectively,~~ were from other advanced manufacturing applications. These include, but are not limited to, ~~electronic thin film,~~industrial technologies, life and health sciences, ~~process and industrial technologies~~ and research and defense.

Net revenues from semiconductor capital equipment manufacture and semiconductor device manufacture customers increased by ~~$80.4~~$65.0 million or ~~38%~~26% for the three months ended ~~September 30, 2017,~~March 31, 2018, compared to ~~the same period in the prior year.~~2017. This increase is comprised of ~~an increase in~~ net semiconductor revenues of $73.8 million in the Vacuum & Analysis segment (the legacy MKS business) and $6.6 million in the Light & Motion segment (the legacy Newport business). These increases are primarily due to volume increases from our semiconductor customers. Net revenues from semiconductor ~~capital equipment manufacture and semiconductor device manufacture~~ customers ~~increased by $326.5 million, or 63% for the nine months ended September 30, 2017, compared to the same period~~ in ~~the prior year. This increase is comprised of an increase in net semiconductor revenues from the~~our Vacuum & Analysis segment of ~~$256.9~~$56.9 million and ~~an increase from the~~in our Light & Motion segment ~~$69.6~~of $8.1 million. These increases are primarily due to volume increases from our semiconductor customers. In addition, the increase in revenue in the Light & Motion segment is due to the fact that the nine month period ended September 30, 2016, only included five months of revenue as a result of the Newport Merger, compared to the respective period in 2017. 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.

~~Net~~ Our net revenues from customers in other advanced markets, which exclude semiconductor capital equipment and semiconductor device ~~product applications,~~manufacture customers, increased by ~~$25.2~~$52.1 million, or ~~15%~~28%, for the three months ended ~~September 30, 2017,~~March 31, 2018, compared to ~~the same period in the prior year. This~~2017. The increase was ~~mainly due~~primarily attributed to ~~an increase~~increases in ~~revenues from customers in the process and~~our industrial technologies ~~market of $14.9 million, electronic thin film market of $5.7 million~~ and life and health sciences market of $5.0 million. Net revenues from customers in other advanced markets increased by $187.5 million for the nine month period ended September 30, 2017, compared to the same period in the prior year. The increase was primarily driven by the Light & Motion segment, whose net revenues increased $168.5 million, compared to the same period in the prior year, due to the fact that the nine month period ended September 30, 2016, only included five months of revenue as a result of the Newport Merger. In addition, revenues from customers in our Vacuum & Analysis segment increased, primarily in the process and industrial technologies market of $9.2 million and electronic thin film market of $8.8 million. Revenues from customers in other advanced markets are made up of many different markets, including electronic thin film, life and health sciences, process and industrial technologies and research and defense.markets.

A significant portion of our net revenues isare from sales to customers in international markets. For ~~the nine months~~both periods ended ~~September 30,~~March 31, 2018 and 2017, ~~and 2016,~~ international net revenues accounted for approximately 50% ~~and 48%~~ of our total net ~~revenues, respectively.~~revenues. A significant portion of our international net revenues were in Japan, South Korea, ~~Japan,~~Germany, Israel ~~China~~ and ~~Germany.~~China. We expect that international net revenues will continue to represent a significant percentage of our total net revenues. Long-lived assets located in the United States were $127.6 million and $124.7 million as of March 31, 2018 and December 31, 2017, respectively, excluding goodwill and intangibles, and long-term tax-related accounts. Long-lived assets located outside of the United States were $78.4 million and $78.5 million as of March 31, 2018 and December 31, 2017, respectively, excluding goodwill and intangibles, and long-term tax-related accounts.

In April 2017, we completed the sale of our Data Analytics Solutions business for total proceeds of $72.5 million, net of cash sold and recorded apre-tax gain of $74.9 million. This business, which had net revenues in 2016 of $12.7 million and was included in the Vacuum & Analysis segment, was no longer a part of our long-term strategic objectives.

The business did not qualify as a discontinued operation as this sale did not represent a strategic shift in our business, nor did the sale have a major effect on our ~~operations, therefore,~~operations. Therefore, the results of operations for all periods are included in our income from operations. The assets and liabilities of this business have not been reclassified or segregated in the consolidated balance sheet or consolidated statements of cash flows as the amounts were immaterial.

The preparation of our consolidated financial statements and related disclosures in conformity with accounting principles generally accepted in the United States ~~of America~~ requires management to make judgments, assumptions and estimates that affect the amounts reported. There have been no material changes in our critical accounting policies since December 31, ~~2016.~~ 2017, other than the adoption of Accounting Standard Update 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASC 606”) as outlined below.

For further information, please see the discussion of critical accounting policies in our Annual Report on Form10-K for the year ended December 31, ~~2016~~2017 in the section captioned “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Estimates.”

We adopted ASC 606 on January 1, 2018 using the modified retrospective method for all contracts not completed as of the date of adoption. The reported results for the three months ended March 31, 2018 reflect the application of ASC 606 guidance while the reported results for 2017 were prepared under the guidance of ASC 605, Revenue Recognition (ASC 605).

We have recorded a net increase to opening retained earnings of $1.8 million as of January 1, 2018 due to the cumulative impact of adopting ASC 606, with the impact primarily related to our service business and certain custom products. The impact to revenues for the quarter ended March 31, 2018 was immaterial as a result of applying ASC 606.

The adoption of ASC 606 represents a change in accounting principle that will more closely align revenue recognition with the delivery of our goods or services and will provide financial statement readers with enhanced disclosures. To achieve this core principle, we apply the following five steps:

Revenue under ASC 606 is recognized when or as obligations under the terms of a contract with our customer have been satisfied and control has transferred to the customer. The majority of our performance obligations, and associated revenue, are transferred to customers at a point in time, generally upon shipment of a product to the customer or receipt of the product by the customer and without significant judgments. Installation services are not significant and are usually completed in a short period of time (normally less than two weeks) and therefore, recorded at a point in time when the installation services are completed, rather than over time as they are not material. Extended warranty, service contracts, and repair services, which are transferred to the customer over time, are recorded as revenue as the services are performed. For repair services, we make an accrual at quarter end based upon historical repair times within our product groups to record revenue based upon the estimated number of days completed to date, which is consistent with ratable recognition. Customized products with no alternative future use to us, and that have an enforceable right to payment for performance completed to date, are also recorded over time. We consider this to be a faithful depiction of the transfer to the customer of revenue over time as the work or service is performed.

Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Performance obligations promised in a contract are identified based on the products or services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the product or service either on its own or together with other resources that are readily available from third parties or from us, and are distinct in the context of the contract, whereby the transfer of the product or service is separately identifiable from other promises in the contract. Sales, value add, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. Our normal payment terms are 30 to 60 days but vary by the type and location of our customers and the products or services offered. The time between invoicing and when payment is due is not significant. For certain products or services and customer types, we require payment before the products or services are delivered to the customer. None of our contracts as of March 31, 2018 contain a significant financing component. Contract assets as of January 1 and March 31, 2018 were immaterial and included in other current assets.

We periodically enter into contracts with our customers in which a customer may purchase a combination of goods and or services, such as products with installation services or extended warranty obligations. These contracts include multiple promises that we evaluate to determine if the promises are separate performance obligations. Once we determine the performance obligations, we then determine the transaction price, which includes estimating the amount of variable consideration to be included in the transaction price, if any. To the extent the transaction price includes variable consideration, we estimate the amount of variable consideration that should be included in the transaction price utilizing either the expected value method or the most likely amount method depending on the method we expect to better predict the amount of consideration to which it will be entitled. There are no constraints on the variable consideration recorded. We then allocate the transaction price to each performance obligation in the contract based on a relative stand-alone selling price charged separately to customers or using an expected cost-plus-margin method. The corresponding revenues are recognized when or as the related performance obligations are satisfied, which are noted above. The impact of variable consideration was immaterial during the three months ended March 31, 2018.

Our standard assurance warranty period is normally 12 to 24 months. We sell separately-priced service contracts and extended warranty contracts related to certain of our products, especially our laser products. The separately priced contracts generally range from 12 to 60 months. We normally receive payment at the inception of the contract and recognize revenue over the term of the agreement in proportion to the costs expected to be incurred in satisfying the obligations under the contract. We have elected to use the practical expedient related to disclosing the remaining performance obligations as of March 31, 2018, as the majority have a duration of less than one year.

Under ASC 606, we expense sales commissions when incurred because the amortization period would have been one year or less. These costs are recorded within selling, general and administration expenses. We have elected to recognize the costs for freight and shipping when control over products has transferred to the customer as an expense in cost of sales.

We monitor and track the amount of product returns and reduce revenue at the time of shipment for the estimated amount of future returns, based on historical experience. We make estimates evaluating our allowance for doubtful accounts. We continuously monitor collections and payments from our customers and maintain a provision for estimated credit losses based upon our historical experience and any specific customer collection issues that we have identified.

Our research and development efforts are 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 durations 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.

We believe that the continued investment in research and development and ongoing development of new products are essential to the expansion of our markets. We expect to continue to make significant investment in research and development activities. We are subject to risks from products not being developed in a timely manner, as well as from 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.

The effective tax rate in 2018 and related income tax expense, was impacted by the Tax Cuts and Jobs Act (the “Act”) which was enacted into law on December 22, 2017. We account for income tax effects resulting from changes in tax laws in accordance with the authoritative guidance, which requires that these tax effects be recognized in the period in which the law is enacted and that the effects are recorded as a component of provision for income taxes from continuing operations. As a result, we recorded provisional amounts as of December 31, 2017 related to the one-time transition tax and the change in U.S. net deferred tax liabilities resulting from the change in the U.S. statutory rate resulting from the enactment of the Act in accordance with the Securities and Exchange Commission Staff Accounting Bulletin No. 118 (“SAB 118”). The provisional amounts associated with the Act were adjusted in the period ended March 31, 2018 and resulted in a decrease to our effective tax rate. We expect to finalize the provisional amounts when we file our 2017 tax returns in October 2018. The reduction in the corporate tax rate from 35% for 2017 to 21% for 2018, as a result of the Act, also impacted our effective tax rate and tax expense in the period ending March 31, 2018 as compared to March 31, 2017. In addition, the effective tax rate in the period ending March 31, 2018 was lower than the U.S. statutory rate due to foreign earnings taxed at lower rates, windfall benefits of stock compensation, and the new deduction for foreign derived intangible income from the Act offset by the tax effects of the new provisions for global intangible low taxed income from the Act and state income taxes.

The effective tax rate for the three ~~and nine~~ months ended ~~September 30,~~March 31, 2017 was lower than the U.S. statutory tax rate mainly due to the ~~geographic mix~~impact of ~~income and profits earned by our international subsidiaries being taxed at~~lower tax rates ~~lower than the U.S. statutory tax rate, the tax benefit of windfall stock compensation deductions and~~on foreign income, the deduction for domestic production ~~activities. These amounts were partially~~activities and windfall stock compensation tax benefit.

At March 31, 2018, the total amount of gross unrecognized tax benefits, which excludes interest and penalties, was approximately $27.9 million. At December 31, 2017, our total amount of gross unrecognized tax benefits, which excludes interest and penalties, was approximately $27.3 million. The net increase from December 31, 2017 was primarily attributable to the addition of reserves for state taxes

and certain non-U.S. items offset by ~~taxes~~decreases from settlement of an IRS audit. At March 31, 2018, excluding interest and penalties, there were $20.5 million of net unrecognized tax benefits that, if recognized, would impact our annual effective tax rate. We accrue interest and, if applicable, penalties for any uncertain tax positions. Interest and penalties are classified as a component of income tax expense. As of March 31, 2018 and December 31, 2017, we had accrued interest on unrecognized tax benefits of approximately $0.5 million and $0.3 million, respectively.

Over the next 12 months it is reasonably possible that we may recognize approximately $1.0 million of previously net ofunrecognized tax benefits, excluding interest and penalties, related to federal, state and foreign tax ~~credits, on actual~~positions as a result of the expiration of statutes of limitation. The U.S. statute of limitations remains open for tax years 2014 through present. The statute of limitations for our tax filings in other jurisdictions varies between fiscal years 2012 through the present. We also have certain federal credit carry-forwards and ~~planned distributions from~~state tax loss and credit carry-forwards that are open to examination for tax years 2000 through the present.

We are subject to examination by U.S. federal, state and foreign tax authorities. The U.S. Internal Revenue Service commenced an examination of our ~~international subsidiaries. Our effective~~U.S. federal income tax ~~rate~~filings for tax years 2015 and 2016 during the ~~three and nine months~~quarter ended September 30, ~~2016~~2017. This audit was ~~23.0% and 24.4%, respectively. Our effective tax rate for~~effectively settled during the ~~three and nine months~~quarter ended ~~September 30, 2016 was lower than~~March 31, 2018. Also during the quarter, we received notification from the U.S. ~~statutory~~Internal Revenue Service that a new audit is scheduled to begin for our U.S. subsidiary, Newport, for tax ~~rate due~~year 2015.

On a quarterly basis, we evaluate both positive and negative evidence that affects the realizability of net deferred tax assets and assess the need for a valuation allowance. The future benefit to ~~the geographic mix of~~be derived from our deferred tax assets is dependent upon our ability to generate sufficient future taxable income ~~and profits earned by our international subsidiaries being taxed at rates lower than the U.S. statutory tax rate, the federal research credit and the impact~~in each jurisdiction of the ~~deduction for domestic production activities.

Our future effective tax rate depends on various factors, including further interpretations and guidance from U.S. federal and state governments on the impact of ~~tax legislation,~~the enactment of the Act, as well as the geographic composition of ourpre-tax income, ~~the results of tax audits,~~ and changes in tax reserves for unrecognized tax benefits. We monitor these factors and timely adjust our estimates of the effective tax rate accordingly. We expect that the geographic mix ofpre-tax income will continue to have a favorable impact on our effective tax ~~rate;~~rate, however the geographic mix ofpre-tax income can change based on multiple factors resulting in changes to the effective tax rate in future periods. We also expect that the impact of the windfall stock compensation tax benefit on the tax rate will vary significantly from quarter to quarter due to the timing of vesting and exercise of stock grants and the impact of changes in our stock price.

~~Our~~The effective tax rate in 2018 could be ~~adversely~~ affected by ~~changes in~~adjustments to the ~~valuation~~provisional amounts recorded under the guidance of SAB 118 for the one-time transition tax and the revaluation of deferred tax assets and ~~liabilities.

Net cash provided by operating activities was $66.1 million for the three months ended March 31, 2017, and resulted from net income of $65.1 million, which included non-cash charges of $36.9 million, offset by a net increase in working capital of $35.9 million. The net increase in working capital was primarily due to a decrease in accrued compensation of $16.8 million, as year-end bonuses were paid, an increase in trade accounts receivable of $15.2 million and an increase in inventories of $11.7 million, related to an increase in business activities and an increase in other current ~~andnon-current~~assets of ~~$9.7~~$1.5 million.

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 outstanding 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 depends 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.

We have repurchased approximately 1,770,000 shares of common stock for approximately $52.0 million pursuant to the program since its adoption. During the ~~nine~~three months ended ~~September 30,~~March 31, 2018 and 2017, there were no repurchases of ~~our~~ common stock. ~~During the nine months ended September 30, 2016 we repurchased approximately 45,000 shares~~

Holders of our common stock ~~for $1.5~~are entitled to receive dividends when and if they are declared by our board of directors. During the three months ended March 31, 2018, we paid cash dividends of $9.8 million in the aggregate, or ~~an average price of $34.50~~$0.18 per share.

~~Our Board~~ During the three months ended March 31, 2017, we paid cash dividends of ~~Directors declared a cash dividend~~$9.4 million in the aggregate, or $0.175 per share during the first, second and third quarters of 2017 that totaled $28.4 million. Our Board of Directors declared a cash dividend of $0.17 per share during the first, second and third quarters of 2016 that totaled $27.2 million.

~~On October 30, 2017 the Company’s Board of Directors declared a quarterly cash dividend of $0.18 per share to be paid on December 8, 2017, to shareholders of record as of November 27, 2017.~~share. Future dividend declarations, if any, as well as the record and payment dates for such dividends, are subject to the final determination of ~~the Company’s~~our Board of Directors. In addition, under the terms of our senior secured Term Loan Facility and our senior secured asset-based revolving credit facility, we may be restricted from paying dividends under certain circumstances.

Our total cash and cash equivalents and short-term marketable investments at September 30, 2017, consisted of $207.7 million held in the United States and $326.9 million held by our foreign subsidiaries, substantially all of which cash held by foreign subsidiaries would be subject to tax in the United States if returned to the United States. We believe our existing United States cash and short-term investment balances are adequate to meet domestic operating needs, including estimated working capital, planned capital expenditure requirements, payment of debt and any future cash dividends, if declared, during the next twelve months and the foreseeable future.

In April 2016, we invested $9.3 million for a minority interest in a private company, which operates in the field of semiconductor process equipment instrumentation. We accounted for this investment using the cost method of accounting. During the fourth quarter of 2016, we recognized an impairment loss on this investment of $5.0 million. In July 2017, we invested an additional $0.1 million in this private company.

In April 2017, we completed the sale of our Data Analytics Solutions business for total proceeds of $72.5 million, net of cash sold and recorded apre-tax gain of $74.9 million. ~~This business, which had net revenues in 2016 of $12.7 million and was included in the Vacuum & Analysis segment, was no longer a part of our long-term strategic objectives.~~

In connection with the completion of the Newport Merger, we entered into a term loan credit agreement (the “Credit Agreement”) with Barclays Bank PLC, as administrative agent and collateral agent, and the lenders from time to time party thereto (the “Lenders”), that provided senior secured financing of $780.0 million, subject to increase at our option in accordance with the Credit Agreement (the “Term Loan Facility”). Borrowings under the Term Loan Facility bear interest per annum at one of the following rates selected by the Company: (a) a base rate determined by reference to the highest of (1) the federal funds effective rate plus 0.50%, (2) the “prime rate” quoted in The Wall Street Journal, (3) a LIBOR rate determined by reference to the costs of funds for U.S. dollar deposits for an interest period of one month adjusted for certain additional costs, plus 1.00%, and (4) a floor of 1.75%, plus, in each case, an applicable ~~margin (that was initially 3.00% and was decreased as described below);~~margin; or (b) a LIBOR rate determined by reference to the costs of funds for U.S. dollar deposits for the interest period relevant to such borrowing adjusted for certain additional costs, subject to a LIBOR rate floor of 0.75%, plus an applicable ~~margin (that was initially 4.00% and was decreased as described below).~~margin. We have elected the interest rate as described in clause (b). The Credit Agreement provides that all loans will be determined by reference to the Base Rate if the LIBOR rate cannot be ascertained, if regulators impose material restrictions on the authority of a lender to make LIBOR rate loans, and for other reasons. The Term Loan Facility was issued with original issue discount of 1.00% of the principal amount thereof.

In June 2016, we entered into Amendment No. 1 (the~~“Re-pricing~~ “Repricing Amendment 1”) to the Credit Agreement by and among the Company, the Lenders and Barclays Bank PLC, as administrative agent and collateral agent for the Lenders. The~~Re-pricing~~ Repricing Amendment 1 decreased the applicable margin for borrowings under our Term Loan Facility to 2.50% for base rate borrowings and 3.50% for LIBOR borrowings and extended the period during which a~~pre-payment~~ prepayment premium may be required for a~~“Re-pricing~~ “Repricing Transaction” (as defined in the Credit Agreement) until six months after the effective date of the~~Re-pricing~~ Repricing Amendment 1. In connection with the execution of the~~Re-pricing~~ Repricing Amendment 1, we paid a~~pre-payment~~ prepayment premium of 1.00%, or $7.3 million, as well as certain fees and expenses of the administrative agent and the Lenders, in accordance with the terms of the Credit Agreement. Immediately prior to the effectiveness of the~~Re-pricing~~ Repricing Amendment 1, we prepaid $50.0 million of principal under the Credit Agreement. In September 2016, we prepaid an additional $60.0 million under the Credit Agreement.

In September 2016, we entered into an interest rate swap agreement, which has a maturity date of September 30, 2020, to fix the rate on $335.0 million of the then-outstanding balance under the Credit Agreement. The rate is fixed at 1.198% per annum plus the applicable credit spread, which was ~~2.25%~~2.00% at ~~September 30, 2017.~~March 31, 2018. At ~~September 30, 2017,~~March 31, 2018, the notional amount of the interest rate swap agreement was $305.0 million.

In December 2016, we entered into Amendment No. 2 (the~~“Re-pricing~~ “Repricing Amendment 2”) to the Credit Agreement by and among the Company, the Lenders and Barclays Bank PLC, as administrative agent and collateral agent for the Lenders. The~~Re-pricing~~ Repricing Amendment 2 decreased the applicable margin for our term loan under the Credit Agreement to 2.75% for LIBOR borrowings and 1.75% for base rate borrowings and reset the period during which a~~pre-payment~~ prepayment premium may be required for a~~Re-pricing~~ Repricing Transaction until six months after the effective date of the~~Re-pricing~~ ~~Amendment.~~ Repricing Amendment 2. In November 2016, prior to the effectiveness of the~~Re-pricing~~ Repricing Amendment 2, we prepaid an additional $40.0 million of principal under the Credit Agreement. In March 2017, ~~the Company~~we prepaid an additional $50.0 million of principal under the Credit Agreement.

In July 6, 2017, we entered into Amendment No. 3 (the~~“Re-pricing~~ “Repricing Amendment 3”) to our Credit Agreement by and among the Company, the Lenders and Barclays Bank PLC, as administrative agent and collateral agent for the Lenders. The~~Re-pricing~~ Repricing Amendment 3 decreased the applicable margin for our term loan under the Credit Agreement to 2.25% for LIBOR rate loans when the Total Leverage Ratio (as defined in the Credit Agreement) is at or above 1.25:1 and decreased to 2.00% when the Total Leverage Ratio iswas below 1.25:1, both with a LIBOR floor of 0.75%. The margin for base rate borrowings ~~will decrease~~decreased to 1.25% when ~~the~~our Total Leverage Ratio iswas at or above 1.25:1 and will decrease to 1.00% when the Total Leverage Ratio is below 1.25:1. The period in which a prepayment premium may be required for a~~Re-pricing~~ Repricing Transaction was reset to six months after the effective date of the~~Re-pricing~~ Repricing Amendment 3.

In July 2017, ~~and~~ August 2017, November 2017 and March 2018 we voluntarily prepaid $50.0 million, $75.0 million, $50.0 million and ~~$75.0~~$50.0 million, respectively, of principal under the Credit Agreement. As of ~~September 30, 2017,~~March 31, 2018, after total~~pre-payments~~ principal prepayments of ~~$325.0~~$425.0 million and regularly scheduled principal payments of $6.5 million, the total outstanding principal balance was ~~$448.5~~$348.5 million. AsThe interest rate as of ~~September 30, 2017,~~March 31, 2018 was 3.648%.

In April 2018, we entered into Amendment No. 4 (the “Repricing Amendment 4”) to the ~~Total Leverage Ratio~~Credit Agreement by and among the Company, the Lenders and Barclays Bank PLC, as administrative agent and collateral agent for the Lenders. The Repricing Amendment 4 decreased the applicable margin for our term loan under the Credit Agreement to 1.75%, with a LIBOR rate floor of 0.75%. The margin for base rate borrowings decreased to 0.75%, with a base rate floor of 1.75%. The period during which a prepayment premium may be required for a Repricing Transaction was ~~below 1.25:1.~~reset to six months after the effective date of the Repricing Amendment 4.

We incurred $28.7 million of deferred finance fees, original issue discount and a~~re-pricing~~ ~~fee~~repricing fees related to the term loans under the Term Loan Facility, which are included in long-term debt in the accompanying consolidated balance sheets and ~~will be~~are being amortized to interest expense over the estimated life of the term loans using the effective interest method. A portion of these fees have been accelerated in connection with the various debt~~pre-payments~~ prepayments during 2016, 2017 and ~~2017.~~2018. As of ~~September 30, 2017,~~March 31, 2018, the remaining balance of the deferred finance fees, original issue discount and~~re-pricing~~ ~~fee~~ repricing fees related to the Term Loan Facility was ~~$13.4~~$7.2 million.

Under the Credit Agreement, we are required to prepay outstanding term loans, subject to certain exceptions, with portions of our annual excess cash flow as well as with the net cash proceeds of certain asset sales, certain casualty and condemnation events and the incurrence or issuance of certain debt. We are also required to make scheduled quarterly payments each equal to 0.25% of the principal amount of the term ~~loans outstanding on July 6, 2017 (the date of theRe-pricing~~ ~~Amendment 3),~~loan, less the amount of certain voluntary and mandatory repayments after such date, with the balance due on the seventh anniversary of the closing date. As a result of making total ~~pre-payments~~prepayments of ~~$325.0~~$425.0 million ~~as of September 30, 2017,~~through March 31, 2018, we are no longer required to make any scheduled quarterly principal payments until maturity of the loan.

All obligations under the Term Loan Facility are guaranteed by certain of our domestic subsidiaries, and are secured by substantially all of our assets and the assets of such subsidiaries, subject to certain exceptions and exclusions.

The Credit Agreement contains customary representations and warranties, affirmative and negative covenants and provisions relating to events of default. If an event of default occurs, the Lenders under the Term Loan Facility will be entitled to take various actions, including the acceleration of amounts due under the Term Loan Facility and all actions generally permitted to be taken by a secured creditor. At ~~September 30, 2017,~~March 31, 2018, we were in compliance with all covenants under the Credit Agreement.

In connection with the completion of the Newport Merger, we also entered into an asset-based credit agreement with Deutsche Bank AG New York Branch, as administrative agent and collateral agent, the other borrowers from time to time party thereto, and the lenders and letters of credit issuers from time to time party thereto (the “ABL Facility”), that provides senior secured financing of up to $50.0 million, subject to a borrowing base limitation. The borrowing base for the ABL Facility at any time equals the sum of: (a) 85% of certain eligible accounts; plus (b) subject to certain notice and field examination and appraisal requirements, the lesser of (i) the lesser of (A) 65% of the lower of cost or market value of certain eligible inventory and (B) 85% of the net orderly liquidation value of certain eligible inventory and (ii) 30% of the borrowing base; minus (c) reserves established by the administrative agent; provided that until the administrative agent’s receipt of a field examination of accounts receivable the borrowing base shall be equal to 70% of the book value of certain eligible accounts. The ABL Facility includes borrowing capacity in the form of letters of credit up to $15.0 million. We have not drawn against the ABL Facility.

Borrowings under the ABL Facility bear interest per annum at one of the following rates selected by us: (a) a base rate determined by reference to the highest of (1) the federal funds effective rate plus 0.50%, (2) the “prime rate” quoted in The Wall Street Journal, and (3) a LIBOR rate determined by reference to the costs of funds for U.S. dollar deposits for an interest period of one month adjusted for certain additional costs, plus 1.00%, plus, in each case, an initial applicable margin of 0.75%; and (b) a LIBOR rate determined by reference to the costs of funds for U.S. dollar deposits for the interest period relevant to such borrowing adjusted for certain additional costs, plus an initial applicable margin of 1.75%. Commencing with the completion of the first fiscal quarter ending after the closing of the ABL Facility, the

applicable margin for borrowings thereunder is subject to upward or downward adjustment each fiscal quarter, based on the average historical excess availability during the preceding quarter.

We have incurred $1.2 million of costs in connection with the ABL Facility, which were capitalized and included in other assets in the accompanying consolidated balance sheets and ~~will be~~are being amortized to interest expense using the straight-line method over the contractual term of five years of the ABL Facility.

In addition to paying interest on outstanding principal under the ABL Facility, we are required to pay a commitment fee in respect of the unutilized commitments thereunder. The initial commitment fee is 0.375% per annum. The total commitment fee recognized in interest expense for the ~~nine~~three months ended ~~September 30, 2017~~March 31, 2018 was ~~$0.2~~$0.1 million. Commencing with the completion of the first fiscal quarter ending after the closing of the ABL Facility, the commitment fee is subject to downward adjustment based on the amount of average unutilized commitments for the three month period immediately preceding such adjustment date. We must also pay customary letter of credit fees and agency fees.

One of our Japanese subsidiaries has lines of credit and short-term borrowing arrangements with two financial institutions which arrangements generally expire and are renewed at ~~three month~~three-month intervals. The lines of credit provide for aggregate borrowings as of ~~September 30, 2017,~~March 31, 2018, of up to an equivalent of ~~$20.4~~$21.6 million U.S. dollars. One of the borrowing arrangements has an interest rate based on the Tokyo Interbank Offer Rate at the time of borrowing and the other has an interest rate based on the Japanese Short-Term Prime Lending Rate. Total borrowings outstanding under these arrangements were $0.9 million at March 31, 2018. There were no borrowings outstanding under these arrangements at ~~September 30, 2017 and~~ December 31, ~~2016.~~2017.

We assumed various revolving lines of credit and a financing facility with the completion of the Newport Merger. These revolving lines of credit and financing facility have no expiration date and provide for aggregate borrowings as of ~~September 30, 2017~~March 31, 2018 of up to an equivalent of ~~$11.1~~$9.9 million U.S. dollars. These lines of credit have a base interest rate of 1.25% plus a Japanese Yen overnight LIBOR rate. Total borrowings outstanding under these arrangements were $3.8 million and $3.0 million at March 31, 2018 and December 31, 2017.

One of our Austrian subsidiaries has ~~four~~various outstanding loans from the Austrian government to fund research and development. These loans are unsecured and do not require principal repayment as long as certain conditions are met. Interest on these loans is payable semi-annually. The interest rates associated with these loans range from 0.75% -to 2.00%.

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 facilitatingoff-balance sheet arrangements or for other contractually narrow or limited purposes. Accordingly, we have nooff-balance sheet arrangements that have or are reasonably expected to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors.

As a result of making total ~~pre-payments~~prepayments since the inception of the Credit Agreement, ~~of $325.0 million, the Company is~~we are no longer required to make any scheduled principal payments until the maturity date of the loan.

In ~~August 2017,~~March 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-05, “Income Taxes (Topic 740).” This standard is an amendment that adopts the language of SAB 118 and aims to address certain circumstances that may arise for registrants in accounting for the income tax effects of the Act and to address any uncertainty or diversity of views in practice regarding the application of Topic 740 in situations where a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting under Topic 740 for certain income tax effects of the Act for the reporting period in which the Act was enacted. The provisions of this ASU were applied to our December 31, 2017 financial statements. We recorded provisional amounts with respect to the Act under SAB 118 at December 31, 2017 and March 31, 2018 and need to complete additional analysis and receive additional guidance from the Internal Revenue Service with respect to provisions of the Act that affect us before the provisional determinations become final. Until we complete our analysis and receive additional guidance, we are not able to determine if the impact of ASU 2018-05 is material to our consolidated financial statements in any period.

In February 2018, the FASB issued ASU 2018-02, “Income Statement – Reporting Comprehensive Income (Topic 220).” The amendments in this standard allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Act. The provisions of this ASU are effective for annual periods beginning after December 15, 2018, including interim periods within those fiscal years. We do not expect adoption of this ASU to have a material impact on our consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815).” This standard better aligns an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. The provisions of this ASU are effective for annual periods beginning after December 15, 2018, including interim periods within those fiscal years. We do not expect adoption of this ASU to have a material impact on our consolidated financial statements.

In ~~May 2017, the FASB issued ASU2017-09,~~ “Compensation-Stock Compensation (Topic 718)-Scope of Modification Accounting.” This standard provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. The provisions of this ASU are effective for annual periods beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted for any interim period for which financial statements have not yet been issued. We do not expect the adoption of this ASU to have a material impact on our consolidated financial statements.

~~In March 2017, the FASB issued ASU2017-07,~~ “Compensation-Retirement Benefits (Topic 715)-Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” This standard requires that an employer disaggregate the service cost component from the other components of net benefit cost. This standard also provides explicit guidance on how to present the service cost component and the other components of the net benefit cost in the income statement and allows only the service cost component of net benefit cost to be eligible for capitalization. The provisions of this ASU are effective for annual periods beginning after December 31, 2017, including interim periods within those fiscal years. Early adoption is permitted as of the beginning of an annual period for which financial statements (interim or annual) have not been issued or made available for issuance. We do not expect adoption of this ASU to have a material impact on our consolidated financial statements.

~~In January 2017, the FASB issued ASU2017-04,~~ “Intangibles-Goodwill and Other (Topic 350).” This standard simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of goodwill. The provisions of this ASU are effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We expect to adopt this new standard in 2017 when we perform our annual goodwill impairment test in the fourth quarter. We do not expect the adoption of this ASU to have a material impact on our consolidated financial statements.

~~In January 2017, the FASB issued ASU2017-01,~~ “Business Combinations (Topic 805)-Clarifying the Definition of a Business.” This standard clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This standard also provides a more robust framework to use in determining when a set of assets and activities is a business. Because the current definition of a business is interpreted broadly and can be difficult to apply, stakeholders indicated that analyzing transactions is inefficient and costly and that the definition does not permit the use of reasonable judgment. The provisions of this ASU are effective for annual periods beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is applicable under certain circumstances. We do not expect adoption of this ASU to have a material impact on our consolidated financial statements.

~~In November 2016, the FASB issued ASU2016-18,~~ ~~“Statement of Cash Flows (Topic 230)-Restricted Cash,” an amendment to ASU2016-15.~~ This standard requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash and restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the~~beginning-of-period~~ ~~andend-of-period~~ total amounts shown on the statement of cash flows. Early adoption is permitted. The provisions of this ASU are effective for annual periods beginning after December 15, 2017, including interim periods within those fiscal years and should be applied at the time of adoption of ASU~~2016-15.~~ ~~We do not expect adoption of this ASU to have a material impact on our consolidated financial statements.~~

~~In October 2016, the FASB issued ASU2016-16,~~ “Income Taxes (Topic 740)-Intra-Entity Transfer of Assets Other Than Inventory.” This standard requires that an entity recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs as opposed to when the assets have been sold to an outside party. The provisions of this ASU are effective for annual periods beginning after December 15, 2017, including interim periods within those fiscal years and early adoption is permitted. We do not expect adoption of this ASU to have a material impact on our consolidated financial statements.

~~In August 2016, the FASB issued ASU2016-15,~~ “Statement of Cash Flows (Topic 230)-Classification of Certain Cash Receipts and Cash Payments.” This standard addresses eight specific cash flow issues with the objective of addressing the diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230. The provisions of this ASU are effective for annual periods beginning after December 15, 2017, including interim periods within those fiscal years. We are currently evaluating the requirements of this ASU and have not yet determined its impact on our consolidated financial statements.

In February 2016, the FASB issued ASU2016-02, “Leases (Topic 842).” This standard requires the recognition of lease assets and liabilities for all leases, with certain exceptions, on the balance sheet. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. This ASU is effective for annual periods beginning after December 15, 2018, including interim periods within those fiscal years. We ~~are currently evaluating~~have reviewed the requirements of the new standard and have formulated a plan for implementation. We have communicated our approach to our Audit Committee and will provide regular updates as appropriate. We are currently working at accumulating a complete population of leases from all of our locations. We have selected a software repository to track all of our lease agreements and to assist in the reporting and disclosure requirements required by the standard. We will continue to assess and disclose the impact that this ASU ~~and~~will have ~~not yet determined its impact~~ on our consolidated financial ~~statements.~~

~~In January 2016, the FASB issued ASU2016-01,~~ ~~“Financial Instruments-Overall (Subtopic825-10):~~ ~~Recognition~~statements, disclosures and Measurement of Financial Assets and Financial Liabilities.” This ASU provides guidance for the recognition, measurement, presentation, and disclosure of financial instruments. The new pronouncement revises accounting related to equity investments and the presentation of certain fair value changes for financial assets and liabilities measured at fair value. Among other things, it amends the presentation and disclosure requirements of equity securities that do not result in consolidation and are not accounted for under the equity method. Changes in the fair value of these equity securities will be recognized directly in net income. This pronouncement is effective for annual periods beginning after December 15, 2017, including interim periods within those fiscal years. We do not expect adoption of this ASU to have a material impact on our consolidated financial statements.controls, when known.

In May 2014, the FASB issued ASU2014-09, “Revenue from Contracts with Customers (Topic 606).” This ASU~~2014-09~~ provides for a single comprehensive model to use in accounting for revenue arising from contracts with customers and ~~will replace~~has replaced most existing revenue recognition guidance in Generally Accepted Accounting ~~Principles when it becomes effective.~~Principles. This ASU~~2014-09~~ is effective for fiscal years and interim periods within those years beginning after December 15, 2017. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. We ~~do not plan to early adopt the standard, but have concluded that we will use~~used the modified retrospective method upon adoption in the first quarter of 2018.

In March, April, May and December 2016 and September 2017, the FASB issued additional updates to the new revenue standard relating to reporting revenue on a gross versus net basis, identifying performance obligations and licensing arrangements, narrow-scope improvements and practical expedients, and technical corrections and improvements, respectively. We have established a cross functional project steering committee and implementation team to identify potential differences that would result from applying the requirements of the new standard to our revenue contracts and related expense line items. We have reviewed our plan for the implementation and will continue to report the status against that plan to our Audit Committee. To date, we have made significant progress in evaluating the potential changes that the The adoption of the new standard may have on our future financial reporting and disclosures. We have identified the various revenue streams, including product revenues, service revenues, installation and training, that could be impacted by Topic 606 and have reviewed individual customer contracts related to these revenue streams. The new revenue standard will primarily impact our recording of repair revenue and customized products, which will be recognized over time under Topic 606 as opposed to a point in time under the current standard. We are in the process of finalizing and documenting our assumptions used in quantifying the impact adoption of the new revenue standard will have on us, which could vary quarter to quarter.Based on our preliminary analysis, we dothis ASU did not ~~expect the adoption of the new guidance to~~ have a material impact on ~~the timing or amount~~our financial statements as described further in Note 3 of ~~our revenue recognition. In addition, we do not expect any major changes to be made to our existing accounting systems or internal controls. We will continue to assess~~ the ~~effect that the new revenue guidance will have on our~~ consolidated financial ~~statements, disclosures and related controls, and will disclose any material effects, if any, when known.~~statements.

Information concerning market risk is contained in the section entitled “Quantitative and Qualitative Disclosures About Market Risk” contained in our Annual Report on Form10-K for the year ended December 31, ~~2016~~2017 filed with the Securities and Exchange Commission on ~~March 1, 2017.~~February 28, 2018. As of ~~September 30, 2017,~~March 31, 2018, there were no material changes in our exposure to market risk from December 31, ~~2016.~~2017.

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 ~~September 30, 2017.~~March 31, 2018. The term “disclosure controls and procedures,” as defined in Rules13a-15(e) and15d-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 Securities and Exchange Commission’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, or persons performing similar functions 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 ~~September 30, 2017,~~March 31, 2018, 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.

There was no change in our internal control over financial reporting (as defined in Rules13a-15(f) and15d-15(f) under the Exchange Act) during the quarter ended ~~September 30, 2017,~~March 31, 2018, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

On March 9, 2016, a putative class action lawsuit captionedDixon Chung v. Newport Corp., et al., Case No.A-16-733154-C, was filed in the District Court, Clark County, Nevada on behalf of a putative class of ~~the Company’s~~ stockholders of Newport for claims related to

The complaint names as defendants the Company, Newport, Merger Sub, and certain then-current and former members of Newport’s former board of directors. The complaint alleges that the named directors breached their fiduciary duties to Newport’s stockholders by agreeing to sell Newport through an inadequate and unfair process, which led to inadequate and unfair consideration, and by agreeing to unfair deal protection devices. The complaint also alleges that the Company, Newport, and Merger Sub aided and abetted the named directors’ alleged breaches of their fiduciary duties.
