Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

1)	Basis of Presentation

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 June 30, 2016 and for the three and six months ended June 30, 2016 and 2015 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, 2015 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 Form 10-Q and do not include all of the information and note disclosures required by United States generally accepted accounting principles (“U.S. GAAP”). The 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 Form 10-K for the year ended December 31, 2015 filed with the Securities and Exchange Commission on February 26, 2016.

On April 29, 2016, the Company completed its acquisition of Newport Corporation which is more fully described in Note 3 below. This transaction was recorded using the purchase method of accounting; accordingly, the financial results of the acquisition are included in the accompanying unaudited condensed consolidated financial statements for the periods subsequent to the acquisition.

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 an on-going basis, management evaluates its estimates and judgments, including those related to revenue recognition, stock-based compensation, inventory, intangible assets, goodwill and other long-lived assets, 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.

Accounting Changes and Error Corrections [Abstract]

Recently Issued Accounting Pronouncements

2)	Recently Issued Accounting Pronouncements

In January 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-01, “Financial Instruments—Overall (Subtopic 825-10): 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 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. The Company does not expect adoption of this ASU to have a material impact on the Company’s consolidated statements of financial position and results of operations.

In March 2016, the FASB issued ASU 2016-09, “Compensation - Stock Compensation (Topic 718)—Improvements to Employee Share-Based Payment Accounting.” This standard simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The provisions of this ASU are effective for annual periods beginning after December 15, 2016, including interim periods within those fiscal years and early adoption is permitted. The Company is currently evaluating the requirements of this ASU and has not yet determined its impact on the Company’s consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, “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. The Company is currently evaluating the requirements of this ASU and has not yet determined its impact on the Company’s consolidated financial statements.

In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330)—Simplifying the Measurement of Inventory.” The amendments in this ASU apply to all inventory that is measured using first-in, first-out or average cost. This standard requires that an entity measure inventory within the scope of this update at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The amendments in this ASU are effective for annual periods beginning after December 15, 2016, 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 statements of financial position and results of operations.

In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” Under this guidance, management will be required to assess an entity’s ability to continue as a going concern, and to provide related footnote disclosures in certain circumstances. The provisions of this ASU are effective for annual periods beginning after December 15, 2016, including interim periods within those fiscal years. The Company does not expect the adoption of this ASU to have an impact on the Company’s consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” which supersedes all existing revenue recognition requirements, including most industry-specific guidance. This standard requires a company to recognize revenue when it transfers goods and services to customers in an amount that reflects the consideration that the company expects to be entitled to in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and assets recognized from costs incurred to obtain or fulfill a contract. This pronouncement is effective for annual periods beginning after December 15, 2017, including interim periods within those fiscal years. 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 has not yet selected a transition method. The Company is currently evaluating the requirements of this ASU and has not yet determined its impact on the Company’s consolidated financial statements.

Acquisitions

3)	Acquisitions

Newport Corporation

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 and sub-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.

The purchase price of Newport consisted of the following:


Cash paid for outstanding shares ⁽¹⁾	$	905,254
Settlement of share-based compensation awards ⁽²⁾		8,824
Cash paid for Newport debt ⁽³⁾		93,200

Total purchase price	$	1,007,278

Less: Cash and cash equivalents acquired		(61,463	)

Total purchase price, net of cash and cash equivalents acquired	$	945,815

⁽¹⁾	Represents cash paid of $23.00 per share for approximately 39,359,000 shares of Newport common stock, without interest and subject to a deduction for any required withholding tax.

⁽²⁾	Represents the vested but not issued portion of Newport share-based compensation awards as of the acquisition date of April 29, 2016.

⁽³⁾	Represents the cash paid for the outstanding balance of Newport’s senior secured revolving credit agreement.

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 11.

Under the acquisition method of accounting, the total estimated 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 expects that all such goodwill and intangible assets will not be deductible for tax purposes.

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


Current assets (including cash)	$	185,388
Inventory		142,914
Intangible assets		394,804
Goodwill		395,784
Property, plant and equipment		119,932
Long-term assets		22,726

Total assets acquired		1,261,548

Current liabilities		94,422
Other long-term liabilities		159,848

Total liabilities assumed		254,270

Fair value of assets acquired and liabilities assumed		1,007,278

Less: cash and cash equivalents acquired		(61,463	)

Total purchase price, net of cash and cash equivalents acquired	$	945,815

The fair value write-up of acquired finished goods inventory was $14,482, the amount of which will be amortized over the expected period during which the acquired inventory is sold. Accordingly, for the three and six months ended June 30, 2016, the Company recorded a $10,119 incremental cost of sales charge associated with the fair value write-up of inventory acquired in the merger with Newport.

The fair value write-up of acquired property, plant and equipment of $36,242 will be amortized over the useful life of the asset. Property, plant and equipment is valued at its value-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.

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


Order backlog	$	12,100	1 year
Customer relationships		243,093	6-18 years
Trademarks and trade names		55,200	Indefinite
Developed technology		75,386	4-8 years
In-process research and development		6,899	Undefined	⁽¹⁾
Leasehold interest		2,126	4-5 years

Total	$	394,804

(1)	The useful lives of in-process research and development will be defined in the future upon further evaluation of the status of these applications.

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.

While the Company uses its best estimates and assumptions as part of the purchase price allocation process to value the assets acquired and liabilities assumed on the acquisition date, its estimates and assumptions are subject to refinement. Fair value estimates are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. The judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact the Company’s results of operations. The finalization of the purchase accounting assessment will result in a change in the valuation of assets acquired and liabilities assumed and may have a material impact on the Company’s results of operations and financial position. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed with a corresponding offset to goodwill to reflect additional information received about facts and circumstances which existed at the date of acquisition. The Company records adjustments to the assets acquired and liabilities assumed subsequent to the purchase price allocation period in the Company’s operating results in the period in which the adjustments were determined. The size and breadth of the Newport Merger will necessitate the use of this measurement period to adequately analyze and assess a number of the factors used in establishing the fair value of certain tangible and intangible assets acquired and liabilities assumed as of the acquisition date and the related tax impacts of any changes made. Any potential adjustments made could be material in relation to the preliminary values presented above.

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 Division reportable segment (see Segment Note 19).

Certain executives from Newport have severance provisions in their respective Newport employment agreements. The agreements include terms that are 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 while the benefit itself will not be distributed until the change in control provision is exercised 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 six months ended June 30, 2016 associated with these severance provisions. The restricted stock units and stock appreciation rights that are eligible for accelerated vesting if the executive exercises his rights, but are not issued as of each reporting period-end, will be excluded from the computation of basic earnings per share and included in the computation of diluted earnings per share for such reporting period.

Pro Forma Results

The following unaudited pro forma financial information presents the combined results of operations of the Company as if the Newport Merger had occurred on January 1, 2015. The unaudited pro forma financial information is not necessarily indicative of what the Company’s condensed 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.


	Three Months Ended June 30,				Six Months Ended June 30,
	2016		2015		2016		2015
Total net revenues	$	358,483	$	365,125	$	687,650	$	734,800

The unaudited pro forma financial information above gives effect primarily to the following:

(1)

Incremental amortization and depreciation expense related to the estimated fair value of identifiable intangible assets and property, plant and equipment from the purchase price allocation.

(2)

Revenue adjustments as a result of the reduction in deferred revenue related to its estimated fair value.

(3)

Incremental interest expense related to the Company’s term loan credit agreement.

(4)

The exclusion of acquisition costs and inventory step-up amortization from the three and six month periods ended June 30, 2016 and the addition of these items to the six month period ended June 30, 2015.

(5)

The estimated tax impact of the above adjustments.

Investment in Reno Sub-Systems, Inc.

On April 27, 2016, the Company invested $9,300 for a minority interest in Reno Sub-Systems, Inc., a Delaware corporation, which operates in the field of semiconductor process equipment instrumentation. The Company accounted for this investment using the cost method of accounting.

Precisive, LLC

On March 17, 2015, the Company acquired Precisive, LLC (“Precisive”) for $12,085, net of cash acquired of $435. The purchase price included a deferred payment amount of $2,600 to cover any potential indemnification claims, which amount was paid to the Sellers in the second quarter of 2016. Precisive is an innovative developer of optical analyzers based on Tunable Filter Spectroscopy, which provide real-time gas analysis in the natural gas and hydrocarbon processing industries, including refineries, hydrocarbon processing plants, gas-to-power machines, biogas processes and fuel gas transportation and metering, while delivering customers a lower total cost of ownership.

The following table summarizes the estimated fair value of the assets acquired and liabilities assumed at the date of the Precisive acquisition:


Current assets	$	693
Non-current assets		18
Intangible assets		5,110
Goodwill		7,042

Total assets acquired		12,863

Total current liabilities assumed		(343	)

Fair value of assets acquired and liabilities assumed		12,520

Less cash acquired		(435	)

Total purchase price, net of cash acquired	$	12,085

Substantially all of the purchase price is deductible for tax purposes. The following table reflects the allocation of the acquired intangible assets and related estimates of useful lives. These acquired intangibles will be amortized on a straight-line basis, which approximates the pattern of use.


Order backlog	$	50	18 months
Customer relationships		1,430	8 years
Exclusive patent license		2,600	10 years
Trade names		210	10 years
Developed technology		820	10 years

Total	$	5,110

The fair value of the acquired intangibles was determined using the income approach. The Precisive 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; (2) potential to leverage the Company’s sales force and intellectual property to attract new customers and revenue; and (3) potential to strengthen and expand into new but complementary markets, including targeting new applications such as natural gas processing, hydrocarbon processing and other oil and gas segments.

The results of this acquisition were included in the Company’s consolidated operations beginning on March 17, 2015. Precisive is included in the Company’s Instruments, Control and Vacuum Products group within the Vacuum & Analysis Division segment.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

5)	Fair Value Measurements

In accordance with the provisions of fair value accounting, a fair value measurement assumes that the transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability and defines fair value based upon an exit price model.

The fair value measurement guidance establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The guidance describes three levels of inputs that may be used to measure fair value:


Level 1		Quoted prices in active markets for identical assets or liabilities assessed as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2		Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange-traded instruments or securities or derivative contracts that are valued using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data.

Level 3		Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.

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.

Assets and liabilities of the Company are measured at fair value on a recurring basis as of June 30, 2016 and are summarized as follows:

Money Market Funds

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

Restricted Cash

The Company has letters of credit, which require it to maintain specified cash deposit balances as collateral. Such amounts have been classified as restricted cash.

Available-For-Sale Investments

As of June 30, 2016, available-for-sale investments consisted of time deposits and drafts denominated in the Euro currency, certificates of deposit, bankers’ acceptance drafts, asset-backed securities (which include auto loans, credit card receivables and equipment trust receivables), corporate obligations, municipal bonds, U.S. treasury obligations, U.S. agency obligations and group insurance contracts.

The Company measures its debt and equity investments at fair value. The Company’s available-for-sale investments are classified within Level 1 and Level 2 of the fair value hierarchy.

Israeli Pension Assets

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.

Derivatives

As a result of the Company’s global operating activities, the Company is exposed to market risks from changes in foreign currency exchange rates, which may adversely affect its operating results and financial position. When deemed appropriate, the Company minimizes its risks from foreign currency exchange rate fluctuations through the use of derivative financial instruments. The principal market in which the Company executes its foreign currency contracts is the institutional market in an over-the-counter environment with a relatively high level of price transparency. The market participants are usually large commercial banks. The forward foreign currency exchange and option contracts are valued using broker quotations, or market transactions and are classified within Level 2 of the fair value hierarchy.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

6)	Derivatives

The Company entered into derivative instruments for risk management purposes only, including derivatives designated as hedging instruments and those utilized as economic hedges. The Company operates internationally and, in the normal course of business, is exposed to fluctuations in interest rates and foreign exchange rates. These fluctuations can increase the costs of financing, investing and operating the business. The Company has used derivative instruments, such as forward contracts and foreign currency option contracts, to manage certain foreign currency exposure.

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

The Company hedges a portion of its forecasted foreign currency-denominated intercompany sales of inventory, over a maximum period of eighteen months, using forward foreign exchange contracts accounted for as cash-flow hedges related to Japanese, South Korean, British, Euro and Taiwanese currencies. To the extent these derivatives are effective in off-setting the variability of the hedged cash flows, and otherwise meet the hedge accounting criteria, changes in the derivatives’ fair value are not included in current earnings but are included in other comprehensive income (loss) (“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.

The Company also enters into forward exchange contracts to hedge certain balance sheet amounts and foreign currency option contracts related to the Israeli Shekel. To the extent the hedge accounting criteria is not met, the related foreign currency forward contracts and foreign currency option contracts are considered as economic hedges and changes in the fair value of these contracts are recorded immediately in earnings in the period in which they occur. These include hedges that are used to reduce exchange rate risks arising from the change in fair value of certain foreign currency-denominated assets and liabilities (i.e., payables, receivables) and other economic hedges where the hedge accounting criteria were not met.

As of June 30, 2016 and December 31, 2015, the Company had outstanding forward foreign exchange contracts with gross notional values of $65,504 and $89,989, respectively. The following tables provide a summary of the primary net hedging positions and corresponding fair values held as of June 30, 2016 and December 31, 2015:

Goodwill and Intangible Assets

8)	Goodwill and Intangible Assets

Goodwill

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.

The changes in the carrying amount of goodwill and accumulated impairment (loss) during the six months ended June 30, 2016 and year ended December 31, 2015 were as follows:


	Six Months Ended June 30,									Twelve Months Ended December 31,

Term Loan Credit Agreement

In connection with the completion of 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 of 3.00%; 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 of 4.00%. The Company has elected Option B for interest rates. The Term Loan Facility was issued with original issue discount of 1.00% of the principal amount thereof.

The term loans are prepayable in whole or in part from time to time, subject to a prepayment premium if prepayment is made on or prior to October 29, 2016 and only in certain circumstances. The Company will be obligated to pay a prepayment fee equal to 1.00% of the amount of the term loans outstanding immediately prior to any amendment resulting in a repricing transaction.

On June 9, 2016, the Company entered into Amendment No. 1 (the “Repricing Amendment”) 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 Repricing Amendment 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 prepayment premium may be required for a “Repricing Transaction” (as defined in the Credit Agreement) until six months after the effective date of the Repricing Amendment. In connection with the execution of the Repricing Amendment, the Company paid a 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 Repricing Amendment, the Company prepaid $50,000 of principal under the Credit Agreement, reducing the outstanding principal under the Credit Agreement from $780,000 to $730,000.

The Company incurred $28,747 of deferred finance fees, original issue discount and a repricing fee related to the term loans, which are included in long-term debt in the accompanying consolidated balance sheets and will be amortized to interest expense over the estimated life of the term loans using the effective interest method.

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 original principal amount of the term loans made on the closing date with such original principal amount reduced by any prepayments (such as the $50,000 prepaid to date), with the balance due on the seventh anniversary of the closing date.

All obligations under the Term Loan Facility are guaranteed by certain of the Company’s domestic subsidiaries, and are secured 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 June 30, 2016, the Company is in compliance with all covenants under the Credit Agreement.

Senior Secured Asset-Based Revolving Credit Facility

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.

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 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.

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 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. 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.

Lines of Credit and Short-Term Borrowing Arrangements

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 June 30, 2016 of up to an equivalent of $22,369 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. There were no borrowings outstanding under these arrangements at June 30, 2016 and December 31, 2015.

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 June 30, 2016 of up to an equivalent of $9,726 U.S. dollars. Both revolving lines of credit have a base interest rate of 1.25% plus a Japanese Yen overnight LIBOR rate.

One of the Company’s Austrian subsidiaries has four 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% - 2.00%.

Product Warranties

12) Product Warranties

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 product warranty liability is included in other current liabilities in the condensed consolidated balance sheet.

Product warranty activities were as follows:

Pension Plans

13)	Pension Plans

As a result of the Newport Merger, the Company has assumed all assets and liabilities of Newport’s defined benefit pension plans, which cover 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.

For financial reporting purposes, the calculation of net periodic pension costs was based upon a number of actuarial assumptions including a discount rate for plan obligations, an assumed rate of return on pension plan assets and an assumed rate of compensation increase for employees covered by the plan. All of these assumptions were based upon management’s judgment, considering all known trends and uncertainties. Actual results that differ from these assumptions would impact future expense recognition and the cash funding requirements of the Company’s pension plans.

The Company has included the net periodic benefit costs for the plans from the date of the acquisition on April 29, 2016 through June 30, 2016. The net periodic benefit costs included the following components:


	Two months ended June 30, 2016
Service cost	$	403
Interest cost on projected benefit obligations		80
Expected return on plan assets		(31	)

	$	452

The projected benefit obligation and plan assets assumed as part of the acquisition, the changes to these amounts and their balances as of June 30, 2016 were as follows:


	June 30, 2016
Change in projected benefit obligations:
Liabilities assumed through acquisition on April 29, 2016	$	22,563
Service cost		403
Interest cost		80
Benefits paid		(121	)
Currency translation adjustments		(598	)

Projected benefit obligation as of June 30, 2016	$	22,327

Change in plan assets:
Assets assumed through acquisition on April 29, 2016		7,907
Company contributions		35
Gain on plan assets		23

Fair value of plan assets as of June 30, 2016		7,965

Funded status	$	(14,362	)

Amounts recognized in the balance sheet:
Current portion of pension liabilities	$	(100	)
Pension liabilities		(14,262	)

Net amount recognized	$	(14,362	)

The Company’s Israeli subsidiaries have pension plans that are accounted for using the shut-down method of accounting. Under the shut-down method, the liability is calculated as if it was payable as of each balance sheet date, on an undiscounted basis and plan assets are reported separate from the pension liability. As a result, the Israeli plan assets and vested benefit obligation are not included in the Company’s plan assets and projected benefit obligation shown above. These Israeli plans had assets of $13,611 and vested benefit obligations of $16,147, which were presented on a gross basis as of June 30, 2016. Israeli plan assets and liabilities are included in other assets and other liabilities, respectively in the accompanying condensed consolidated balance sheet.

Other Pension-Related Assets

As of June 30, 2016, the Company had assets with an aggregate market value of $5,930, which it has set aside in connection with its German pension plans. These assets are invested in group insurance contracts through the insurance company administering these plans, in accordance with applicable pension laws. Because these assets were not separate legal assets of the pension plan, they were not included in the Company’s plan assets shown above. However, the Company has designated such assets to pay pension benefits and these assets are included in long-term investments in the accompanying condensed consolidated balance sheet.

Income Taxes

14)	Income Taxes

The Company’s effective tax rate for the three and six months ended June 30, 2016 was 25.5% and 26.0%, respectively. The effective tax rate for the three and six months ended June 30, 2016 was lower than the U.S. statutory tax rate primarily due to the geographic mix of income and profits earned by the Company’s international subsidiaries being taxed at rates lower than the U.S. statutory tax rate, the federal research credit and the deduction for domestic production activities, offset by non-deductible acquisition-related costs and state income taxes. The Company’s effective tax rate for the three and six months ended June 30, 2015 was 29.1% and 29.0%, respectively. The effective tax rate for the three and six months ended June 30, 2015 was lower than the U.S. statutory tax rate primarily due to the geographic mix of income and profits earned by the Company’s international subsidiaries being taxed at rates lower than the U.S. statutory tax rate and the deduction for domestic production activities.

As of June 30, 2016, the total amount of gross unrecognized tax benefits, which excludes interest and penalties, was approximately $23,740. At December 31, 2015, the total amount of gross unrecognized tax benefits, which excludes interest and penalties, was approximately $4,332. The net increase from December 31, 2015 was primarily attributable to the addition of historical Newport gross unrecognized tax benefits included as a result of the Newport Merger. As of June 30, 2016, if these gross unrecognized tax benefits were recognized in a future period, the timing of which is not estimable, the net unrecognized tax benefit of $20,000, excluding interest and penalties, would impact the Company’s effective tax rate. The Company accrues interest expense, and if applicable, penalties, for any uncertain tax positions.

Interest and penalties are classified as a component of income tax expense. As of June 30, 2016 and December 31, 2015, the Company had accrued interest on unrecognized tax benefits of approximately $746 and $157, respectively.

Over the next 12 months it is reasonably possible that the Company may recognize approximately $3,015 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 tax filings for tax years 2011 through 2013 during the quarter ended March 31, 2015. The audit was effectively settled during the three months ended December 31, 2015 upon the Company’s acceptance of the income tax examination changes. As part of the audit, the Company consented to extend the U.S. statute of limitations for tax year 2011 until September 30, 2016.

The U.S. statute of limitations remains open for tax years 2011 through present. The statute of limitations for the Company’s tax filings in other jurisdictions varies between fiscal years 2007 through present. The Company also has certain federal credit carry-forwards and state tax loss and credit carry-forwards that are open for examination for tax years 2000 through present.

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


	Three Months Ended June 30,				Six Months Ended June 30,
	2016		2015		2016		2015
Numerator:
Net income	$	9,210	$	33,220	$	26,773	$	67,006

Denominator:
Shares used in net income per common share – basic		53,461,000		53,384,000		53,348,000		53,299,000
Effect of dilutive securities:
Stock options, restricted stock, stock appreciation rights and employee stock purchase plan		345,000		205,000		337,000		260,000

Shares used in net income per common share – diluted		53,806,000		53,589,000		53,685,000		53,559,000

Net income per common share:
Basic	$	0.17	$	0.62	$	0.50	$	1.26
Diluted	$	0.17	$	0.62	$	0.50	$	1.25

Basic earnings per share (“EPS”) is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding during the period. The computation of diluted EPS is similar to the computation of basic EPS except that the denominator is increased to include the number of additional common shares that would have been outstanding (using the treasury stock method) if securities containing potentially dilutive common shares (stock options, restricted stock units and stock appreciation rights) had been converted to such common shares, and if such assumed conversion is dilutive.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Stock-Based Compensation

18)	Stock-Based Compensation

In connection with the completion of the Newport Merger, the Company assumed:

•

all restricted stock units (“RSUs”) granted under any Newport equity plan that were outstanding immediately prior to the effective time of the Newport Merger, and as to which shares of Newport common stock were not fully distributed in connection with the closing of the Newport Merger, and

•

all stock appreciation rights granted under any Newport equity plan, whether vested or unvested, that were outstanding immediately prior to the effective time of the Newport Merger.

As of the effective time of the Newport Merger, based on a formula provided in the Merger Agreement, (a) such RSUs were converted automatically into RSUs with respect to 360,674 shares of the Company’s common stock (the “Assumed RSUs”), and (b) such 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 shares for outside directors that were part of the Newport Deferred Compensation plan (the “DC Plan”), of which 19,137 shares were released from the DC Plan in May 2016. The remaining 17,462 shares 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 on the 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 of 1933 on the Registration Statement on Form S-8.

During the six months ended June 30, 2016, the Company granted 695,284 RSUs with a weighted average grant date fair value of $35.17 and the Company did not grant any stock appreciation rights during the six months ended June 30, 2016.

The total stock-based compensation expense included in the Company’s consolidated statements of income and comprehensive income was as follows:


	Three Months Ended June 30,				Six Months Ended June 30,
	2016		2015		2016		2015
Cost of revenues	$	890	$	578	$	1,330	$	1,057
Research and development expense		689		428		1,063		850
Selling, general and administrative expense		8,937		2,560		12,275		4,871

Total pre-tax stock-based compensation expense	$	10,516	$	3,566	$	14,668	$	6,778

At June 30, 2016, the total compensation expense related to unvested stock-based awards granted to employees, officers and directors under the Company’s stock–based compensation plan that had not been recognized was $33,207, net of estimated forfeitures. 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.

The following table presents the activity for RSUs under the Plan:


	Six Months Ended June 30, 2016
	Non-vested RSUs			Weighted Average Grant Date Fair value
Non-vested RSUs – beginning of period		733,162		$	30.94
Assumed shares from Newport Merger		324,075			35.01
Granted		695,284			35.17
Vested		(429,484	)		31.17
Forfeited or expired		(37,585	)		32.56

Non-vested RSUs – end of period		1,285,452		$	34.19

For the three and six months ended June 30, 2016, there were approximately 1,000 weighted-average restricted stock units that would have an anti-dilutive effect on EPS, and would thus need to be excluded from the computation of diluted weighted-average shares.

As of June 30, 2015, stock options and restricted stock units related to an aggregate of approximately 772,000 shares were

outstanding. For the three and six months ended June 30, 2015, there were no weighted-average shares of restricted stock units and stock options that were excluded from the computation of diluted weighted-average shares outstanding that would have an anti-dilutive effect on EPS.

At June 30, 2016, the Company’s outstanding and exercisable stock appreciation rights, the weighted-average base value, the weighted average remaining contractual life and the aggregate intrinsic value thereof, were as follows:


	Number of shares		Weighted Average Base Value		Weighted Average Remaining Contractual Life (years)		Aggregate Intrinsic Value
Stock appreciation rights outstanding		746,184	$	27.87		4.3	$	11,334
Stock appreciation rights exercisable		506,436	$	26.57		3.7	$	8,349

Segment Reporting [Abstract]

Business Segment, Geographic Area, Product and Significant Customer Information

19)	Business Segment, Geographic Area, Product and Significant Customer Information

The Company is a global provider of instruments, subsystems and process control solutions that measure, control, power, monitor and analyze critical parameters of advanced manufacturing processes to improve process performance and productivity. The Company also provides services relating to the maintenance and repair of products it sells, software maintenance, 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.

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 the Vacuum & Analysis Division and the Light & Motion Division.

The Vacuum & Analysis Division provides a broad range of instruments, components, subsystems and software 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 and information technology, ozone generation and delivery, RF & DC power, reactive gas generation and vacuum technology.

The Light & Motion Division 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 and optics.

The Company derives its segment results directly from the manner in which results are reported in its management reporting system. The accounting policies that the Company uses to derive reportable segment results are substantially the same as those used for external reporting purposes. The Company does not disclose external or intersegment revenues separately by reportable segment as this information is not presented to the CODM for decision making purposes.

The following is net revenues by reportable segment:


	Three Months Ended June 30,				Six Months Ended June 30,
	2016		2015		2016		2015
Vacuum & Analysis Division	$	207,359	$	217,966	$	391,040	$	431,805

Commitments and Contingencies

20)	Commitments and Contingencies

On March 9, 2016, a putative class action lawsuit captioned Dixon 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. The complaint, filed on March 9, 2016, named as defendants the Company, Newport, Merger Sub, and certain 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 captioned Hubert 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 the Newport’s stockholders for claims related to the Merger Agreement. The complaint names as defendants the Company, Newport, and Merger Sub and the then-current members of Newport’s former board of directors. It 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, by agreeing to unfair deal protection devices, and by omitting material information from the Proxy. 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, and an award of attorneys’ and other fees and costs, among other relief.

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.

The Company believes that the claims asserted in the complaints have no merit and the Company, Newport, Merger Sub and the named directors intend to defend vigorously against these claims.

We are also subject to various other legal proceedings and claims, which have arisen in the ordinary course of business. In our opinion, the ultimate disposition of these matters will not have a material adverse effect on our results of operations, financial condition or cash flows.

Recently Issued Accounting Pronouncements (Policies)	6 Months Ended
Recently Issued Accounting Pronouncements (Policies)	Jun. 30, 2016
Accounting Changes and Error Corrections [Abstract]
Recently Issued Accounting Pronouncements	In January 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-01, “Financial Instruments—Overall (Subtopic 825-10): 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 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. The Company does not expect adoption of this ASU to have a material impact on the Company’s consolidated statements of financial position and results of operations. In March 2016, the FASB issued ASU 2016-09, “Compensation - Stock Compensation (Topic 718)—Improvements to Employee Share-Based Payment Accounting.” This standard simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The provisions of this ASU are effective for annual periods beginning after December 15, 2016, including interim periods within those fiscal years and early adoption is permitted. The Company is currently evaluating the requirements of this ASU and has not yet determined its impact on the Company’s consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “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. The Company is currently evaluating the requirements of this ASU and has not yet determined its impact on the Company’s consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330)—Simplifying the Measurement of Inventory.” The amendments in this ASU apply to all inventory that is measured using first-in, first-out or average cost. This standard requires that an entity measure inventory within the scope of this update at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The amendments in this ASU are effective for annual periods beginning after December 15, 2016, 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 statements of financial position and results of operations. In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” Under this guidance, management will be required to assess an entity’s ability to continue as a going concern, and to provide related footnote disclosures in certain circumstances. The provisions of this ASU are effective for annual periods beginning after December 15, 2016, including interim periods within those fiscal years. The Company does not expect the adoption of this ASU to have an impact on the Company’s consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” which supersedes all existing revenue recognition requirements, including most industry-specific guidance. This standard requires a company to recognize revenue when it transfers goods and services to customers in an amount that reflects the consideration that the company expects to be entitled to in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and assets recognized from costs incurred to obtain or fulfill a contract. This pronouncement is effective for annual periods beginning after December 15, 2017, including interim periods within those fiscal years. 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 has not yet selected a transition method. The Company is currently evaluating the requirements of this ASU and has not yet determined its impact on the Company’s consolidated financial statements.

- Definition

Investments in debt and equity securities which are categorized neither as held-to-maturity nor trading and which are intended to be sold or mature more than one year from the balance sheet date or operating cycle, if longer. Such securities are reported at fair value; unrealized gains (losses) related to Available-for-sale Securities are excluded from earnings and reported in a separate component of shareholders' equity (other comprehensive income), unless the Available-for-sale security is designated as a hedge or is determined to have had an other than temporary decline in fair value below its amortized cost basis. All or a portion of the unrealized holding gain (loss) of an Available-for-sale security that is designated as being hedged in a fair value hedge is recognized in earnings during the period of the hedge, as are other than temporary declines in fair value below the cost basis for investments in equity securities and debt securities that an entity intends to sell or it is more likely than not that it will be required to sell before the recovery of its amortized cost basis. Other than temporary declines in fair value below the cost basis for debt securities categorized as Available-for-sale that an entity does not intend to sell and for which it is not more likely than not that the entity will be required to sell before the recovery of its amortized cost basis are bifurcated into credit losses and losses related to all other factors. Other than temporary declines in fair value below cost basis related to credit losses are recognized in earnings, and losses related to all other factors are recognized in other comprehensive income.
