ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 28, 2013
ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'
ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'
	NOTE 1        ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Organization
	Newport Corporation, including its subsidiaries (collectively, the Company), is a global supplier of advanced-technology products and systems, including lasers, photonics instrumentation, precision positioning and vibration isolation products and systems, optical components, subassemblies and subsystems and three-dimensional non-contact measurement equipment.  The Company’s products are used worldwide in a variety of industries including scientific research, defense and security, microelectronics, life and health sciences and industrial markets.  Prior to 2013, the Company operated within three distinct business segments: its Lasers Division, its Photonics and Precision Technologies (PPT) Division and its Ophir Division.  In January 2013, the Company reorganized its operations to create three new operating groups: its Photonics Group, its Lasers Group and its Optics Group, which represent the Company’s reportable segments commencing in 2013.  The information related to the Company’s reportable segments for the years 2011 and 2012, which is included in the accompanying financial statements, has been restated to conform to these new reportable segments.  All of these groups offer a broad array of advanced technology products and services to original equipment manufacturer (OEM) and end-user customers across a wide range of applications in all of the Company’s targeted end markets.
	Basis of Presentation
	The accompanying financial statements include the accounts of Newport Corporation and its wholly owned and majority owned subsidiaries.  All intercompany transactions and balances have been eliminated in consolidation.
	The Company uses a 52/53-week accounting fiscal year ending on the Saturday closest to December 31, and its fiscal quarters end on the Saturday that is generally closest to the end of each corresponding calendar quarter.  Fiscal year 2013 (referred to herein as 2013) ended on December 28, 2013, fiscal year 2012 (referred to herein as 2012) ended December 29, 2012 and fiscal year 2011 (referred to herein as 2011) ended December 31, 2011.  Each of these fiscal years consisted of 52 weeks.
	Foreign Currency Translation
	Assets and liabilities for the Company’s international operations are translated into U.S. dollars using current rates of exchange in effect at the balance sheet dates.  Items of income and expense for the Company’s international operations are translated using the monthly average exchange rates in effect for the period in which the items occur.  The functional currency for all of the Company’s international operations is the local currency, except for Israel and Canada, for which the functional currency is the U.S. dollar.  Where the local currency is the functional currency, the resulting translation gains and losses are included as a component of stockholders’ equity in accumulated other comprehensive income (loss).  Where the U.S. dollar is the functional currency, the resulting translation gains and losses are included in the results of operations.  Realized foreign currency transaction gains and losses for all entities are included in the results of operations.
	Derivative Instruments
	The Company recognizes all derivative financial instruments in the consolidated financial statements at fair value regardless of the purpose or intent for holding the instrument.  The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and further, on the type of hedging relationship.  The Company does not engage in currency speculation; however, the Company uses forward exchange contracts and foreign currency option contracts to mitigate the risks associated with certain foreign currency transactions entered into in the ordinary course of business, primarily foreign currency denominated receivables and payables.  The Company has not elected hedge accounting treatment and, accordingly, changes in fair values are reported in the consolidated statements of operations and comprehensive income (loss).  The forward exchange contracts and foreign currency option contracts generally result in the Company paying or receiving net amounts, based on the change in foreign currency rates between inception of the contracts and maturity of the contracts.  If the counterparties to the contracts (typically highly rated banks) do not fulfill their obligations to deliver the contracted currencies, the Company could be at risk for any currency related fluctuations.  Changes in fair values and transaction gains and losses are included in interest and other expense, net in the results of operations.  Such amounts were not material for 2013, 2012 or 2011.
	Cash and Cash Equivalents and Marketable Securities
	The Company considers cash and highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents.  Investments with original maturities exceeding three months at the date of purchase are classified as marketable securities.  All marketable securities are classified as available for sale and are recorded at market value using the specific identification method; unrealized gains and losses are reflected in accumulated other comprehensive income (loss) unless the Company determines there is an other-than-temporary impairment, in which case the loss is recorded in the consolidated statements of operations and comprehensive income (loss).
	Restricted Cash
	The Company has certain agreements, which require it to maintain specified cash balances as collateral.  Such amounts have been classified as restricted cash.
	Accounts Receivable
	The Company records reserves for specific receivables deemed to be at risk for collection, as well as a reserve based on its historical collections experience. The Company estimates the collectability of customer receivables on an ongoing basis by reviewing past due invoices and assessing the current creditworthiness of each customer.  A considerable amount of judgment is required in assessing the ultimate realization of these receivables.
	Concentrations of Credit Risk
	Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, foreign exchange contracts and accounts receivable.  The Company maintains cash and cash equivalents with and purchases its foreign exchange contracts from major financial institutions and performs periodic evaluations of the relative credit standing of these financial institutions in order to limit the amount of credit exposure with any one institution.  Substantially all of the Company’s marketable securities are currently invested in Euro Over Night Index Average (Eonia) securities or certificates of deposit.  The Company’s senior financial management and the Company’s Board of Directors periodically review the marketable securities to determine the appropriate investment strategy.
	The Company’s customers are concentrated in the scientific research, defense and security, microelectronics, life and health sciences and industrial markets, and their ability to pay may be influenced by the prevailing macroeconomic conditions present in these markets.  Receivables from the Company’s customers are generally unsecured.  To reduce the overall risk of collection, the Company performs ongoing evaluations of its customers’ financial condition.  For the years ended December 28, 2013, December 29, 2012 and December 31, 2011, no customer accounted for 10% or more of the Company’s net sales or 10% or more of the Company’s gross accounts receivable as of the end of such year.
	Pension Plans
	Several of the Company’s non-U.S. subsidiaries have defined benefit pension plans covering substantially all full-time employees at those subsidiaries.  Some of the plans are unfunded, as permitted under the plans and applicable laws.  For financial reporting purposes, the calculation of net periodic pension costs is 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 are based upon management’s judgment, considering all known trends and uncertainties.
	The Company accounts for its Israeli pension plans 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.  In addition, the assets and liabilities of the plans are accounted for on a gross basis.
	Inventories
	Inventories are stated at the lower of cost (determined on a first-in, first-out (FIFO) basis) or fair market value and include materials, labor and manufacturing overhead.  Inventories that are expected to be sold within one year are classified as current inventories and are included in inventories, and inventories that the Company expects to hold for longer than one year are included in investments and other assets.  The Company writes down excess and obsolete inventory to net realizable value.  Once the Company writes down the carrying value of inventory, a new cost basis is established, and the Company does not increase the newly established cost basis based on subsequent changes in facts and circumstances.  In assessing the ultimate realization of inventories, the Company makes judgments as to future demand requirements and compares those requirements with the current or committed inventory levels.  The Company records any amounts required to reduce the carrying value of inventory to net realizable value as a charge to cost of sales.
	Property and Equipment
	Property and equipment are stated at cost, less accumulated depreciation.  Depreciation expense includes amortization of assets under capital leases.  Depreciation is recorded on a straight-line basis over the estimated useful lives of the assets as follows:
	Buildings and improvements	3 to 40 years
	Machinery and equipment	2 to 20 years
	Office equipment	3 to 10 years
	Leasehold improvements are amortized over the shorter of their estimated useful life or the remaining lease term.
	Capitalized Software Costs
	All direct costs related to developing internal use software during the application development stage are capitalized and amortized using the straight-line method over the estimated useful lives of the assets.  Costs incurred in the preliminary project stage, maintenance costs and training costs are expensed as incurred.
	Intangible Assets, including Goodwill
	Developed technology is amortized on a straight line basis over 10 to 20 years, depending on the life of the product technology.  Intangible assets related to customer relationships are primarily amortized over a period of up to 10 years on an accelerated basis.  In-process research and development is amortized on a straight line basis over the product’s estimated useful life upon completion of the technology.  Other intangible assets include acquired backlog, product trademarks and trade names, non-competition agreements and defensible assets.  With the exception of product trademarks and trade names, such assets are amortized on a straight line basis over a period of three months to 10 years, depending on the asset.  Trademarks and trade names associated with products are amortized on a straight line basis over the estimated remaining life of the product technology, which ranges from 10 to 20 years.  Trademarks and trade names associated with a business have indefinite lives and are not amortized.
	Goodwill represents the excess of the purchase price of the net assets of acquired entities over the fair value of such assets.  Under Accounting Standards Codification (ASC) 350, Intangibles — Goodwill and Other, goodwill and other indefinite-lived intangible assets are not amortized but are tested for impairment at least annually or when circumstances exist that would indicate an impairment of such goodwill or other intangible assets.  The Company performs the annual impairment test as of the beginning of the fourth quarter of each year.  A two-step test is used to identify the potential impairment and to measure the amount of impairment, if any.  The first step is based upon a comparison of the fair value of each of the Company’s reporting units, as defined, and the carrying value of the reporting unit’s net assets, including goodwill.  If the fair value of the reporting unit exceeds its carrying value, goodwill is considered not to be impaired; otherwise, step two is required.  Under step two, the implied fair value of goodwill, calculated as the difference between the fair value of the reporting unit and the fair value of the net assets of the reporting unit, is compared with the carrying value of goodwill.  The excess of the carrying value of goodwill over the implied fair value represents the amount impaired.
	The Company determines its reporting units by identifying those operating segments or components for which discrete financial information is available which is regularly reviewed by the management of that unit.  For any acquisition, the Company allocates goodwill to the applicable reporting unit at the completion of the purchase price allocation through specific identification.
	Fair value of the Company’s reporting units is determined using a combination of a comparative company analysis and a discounted cash flow analysis.  The comparative company analysis establishes fair value by applying market multiples to the Company’s revenue and earnings before interest, income taxes, depreciation and amortization.  Such multiples are determined by comparing the Company’s reporting units with other publicly traded companies within the respective industries that have similar economic characteristics.  In addition, a control premium is added to reflect the value an investor would pay to obtain a controlling interest, which is consistent with the median control premium for transactions in those industries in which the Company does business.  The discounted cash flow analysis establishes fair value by estimating the present value of the projected future cash flows of each reporting unit and applying a terminal growth rate.  The present value of estimated discounted future cash flows is determined using the Company’s estimates of revenue and costs for the reporting units, using a combination of historical results, industry data and competitor data, as well as appropriate discount rates.  The discount rate is determined using a weighted-average cost of capital that incorporates market participant data and a risk premium applicable to each reporting unit.  See Note 5 for an explanation of impairment charges recorded during 2012.  There were no impairment charges in 2013 or 2011.
	Long-Lived Assets
	The Company assesses the impairment of long-lived assets, other than goodwill and other indefinite-lived intangible assets, to determine if their carrying value may not be recoverable.  The determination of related estimated useful lives and whether or not these assets are impaired involves significant judgments, related primarily to the future profitability and/or future value of the assets.  Changes in the Company’s strategic plan and/or other-than-temporary changes in market conditions could significantly impact these judgments and could require adjustments to recorded asset balances.  Long-lived assets are evaluated for impairment at least annually, as well as whenever an event or change in circumstances has occurred that could have a significant adverse effect on the fair value of long-lived assets.  In the fourth quarter of 2012, in connection with the Company’s annual evaluation of long-lived assets, it determined that certain assets of its former Ophir Division (which are now a part of the Company’s Photonics Group) were impaired.  Accordingly, the Company recorded an impairment charge of $0.5 million related to fixed assets.  There were no impairment charges during 2013 or 2011.
	Warranty
	Unless otherwise stated in the Company’s product literature or in its agreements with customers, products sold by the Company’s Photonics and Optics Groups generally carry a one-year warranty from the original invoice date on all product materials and workmanship, other than filters and gratings products, which generally carry a 90-day warranty, and laser beam profilers and dental CAD/CAM scanners, which generally carry a two-year warranty.  Products sold by the Photonics and Optics Groups to original equipment manufacturer (OEM) customers carry warranties generally ranging from 15 to 19 months.  Products sold by the Company’s Lasers Group carry warranties that vary by product and product component, but generally range from 90 days to two years.  In certain cases, such warranties for Lasers Group products are limited by either a set time period or a maximum amount of hourly usage of the product, whichever occurs first.  Defective products will be either repaired or replaced, generally at the Company’s option, upon meeting certain criteria.  The Company accrues a provision for the estimated costs that may be incurred for warranties relating to a product (based on historical experience) as a component of cost of sales.
	Environmental Reserves
	The Company accrues for losses associated with environmental remediation obligations when such losses are probable and reasonably estimable.  Accruals for estimated losses from environmental remediation obligations generally are recognized no later than completion of the remedial feasibility study.  Such accruals are adjusted as further information develops or circumstances change.  Costs of future expenditures are discounted to their present value.  Recoveries of environmental remediation costs from other parties are recognized as assets when their receipt is deemed probable.  See Note 10 for additional information.
	Revenue Recognition
	The Company recognizes revenue after title to and risk of loss of products have passed to the customer, or delivery of the service has been completed, provided that persuasive evidence of an arrangement exists, the price is fixed or determinable and collectability is reasonably assured.  Title to and risk of loss of products generally pass to the customer upon delivery, but in certain cases pass upon acceptance.  The Company recognizes revenue and related costs for arrangements with multiple deliverables, such as equipment and installation, as each element is delivered or completed based upon its relative selling price, determined based upon the price that would be charged on a standalone basis.  If a portion of the total contract price is not payable until installation is complete, the Company does not recognize such portion as revenue until completion of installation.  Revenue for extended service contracts is recognized over the related contract periods.  Revenue for programs involving design and development services and delivery of product prototypes and/or other deliverables is recognized upon the completion of specified milestones, or over the term of the program based upon the percentage of completion of the program, depending on the terms of the associated contract.  Certain sales to international customers are made through third-party distributors and revenue is recognized upon the sale to the distributor.  A discount below list price is generally provided at the time the product is sold to the distributor, and such discount is reflected as a reduction in net sales.  Freight costs billed to customers are included in net sales, and freight costs incurred are included in selling, general and administrative expenses.  Sales taxes collected from customers are recorded on a net basis and any amounts not yet remitted to tax authorities are included in accrued expenses and other current liabilities.
	Customers (including distributors) generally have 30 days from the original invoice date (generally 60 days for international customers) to return a standard catalog product purchase for exchange or credit.  Catalog products must be returned in the original condition and meet certain other criteria.  Custom, option-configured and certain other products as defined in the terms and conditions of sale cannot be returned without the Company’s consent.  For certain products, the Company establishes a sales return reserve based on the historical product returns.
	Advertising
	The Company expenses the costs of advertising as incurred, except for the costs of its product catalogs, which are accounted for as prepaid supplies until they are distributed to customers or are no longer expected to be used.  Capitalized catalog costs were not material at December 28, 2013 and December 29, 2012.  Advertising costs, including the costs of the Company’s participation at industry trade shows, totaled $4.2 million, $3.9 million and $4.2 million for 2013, 2012 and 2011, respectively.
	Shipping and Handling Costs
	The Company expenses the costs of shipping and handling as incurred.  Shipping and handling costs of $4.7 million, $5.2 million and $5.0 million are included in selling, general and administrative expenses for 2013, 2012 and 2011, respectively.
	Research and Development
	All research and development costs are expensed as incurred.
	Non-Controlling Interests
	In October 2011, the Company acquired Ophir Optronics Ltd. (Ophir), as discussed in Note 2.  As of December 28, 2013, Ophir’s subsidiaries, Ophir Japan, Ltd. in Japan, Ophir Optronics GmbH in Germany, and Optical Metrology Ltd. in Israel, had non-controlling interest holders of 33.3%, 25% and 14.1%, respectively.  Earnings (losses) attributable to the non-controlling interests are separately identified in the Company’s consolidated financial statements.
	During the first quarter of 2014, Ophir purchased all shares owned by the holders of the non-controlling interests in Optical Metrology Ltd for $0.9 million.
	Income Taxes
	The Company utilizes the asset and liability method of accounting for income taxes.  Deferred income taxes are recognized for the future tax consequences of temporary differences using enacted statutory tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  Temporary differences include the difference between the financial statement carrying amounts, and the tax bases of existing assets and liabilities as well as operating loss and tax credit carryforwards.  In accordance with the provisions of ASC 740, a valuation allowance for deferred tax assets is recorded to the extent the Company cannot determine that the ultimate realization of the net deferred tax assets is more likely than not.
	The Company utilizes ASC 740-10-25, Income Taxes - Recognition, for the recognition, measurement and disclosure of uncertain tax positions.  Under ASC 740-10-25, income tax positions must meet the more-likely-than-not threshold to be recognized in the financial statements.  The Company’s policy is to record interest and penalties associated with unrecognized tax benefits as income tax expense.
	Income (loss) per Share
	Basic income (loss) per share is computed by dividing net income (loss) by the weighted-average number of shares of common stock outstanding during the period.  Diluted income per share is computed using the weighted-average number of shares of common stock outstanding during the period plus the dilutive effects of common stock equivalents (restricted stock units, stock options and stock appreciation rights) outstanding during the period, determined using the treasury stock method.  Diluted loss per share excludes the antidilutive effects of common stock equivalents outstanding during the periods.
	Stock-Based Compensation
	The Company accounts for stock-based compensation in accordance with ASC 718, Compensation — Stock Compensation.  Under the fair value recognition provision of ASC 718, stock-based compensation cost is estimated at the grant date based on the fair value of the award.  The Company estimates the fair value of stock options and stock appreciation rights granted using the Black-Scholes-Merton option pricing model and a single option award approach.  The fair value of restricted stock unit awards is based on the closing market price of the Company’s common stock on the date of grant.
	Determining the appropriate fair value of stock options and stock appreciation rights at the grant date requires significant judgment, including estimating the volatility of the Company’s common stock and expected term of the awards.  The Company computes expected volatility based on historical volatility over the expected term.  The expected term represents the period of time that stock options and stock appreciation rights are expected to be outstanding and is determined based on historical experience, giving consideration to the contractual terms of the stock-based awards, vesting schedules and expected exercise behavior.
A substantial portion of the Company’s restricted stock unit awards vest based upon the achievement of one or more financial performance thresholds established by the Compensation Committee of the Company’s Board of Directors.  Currently, such performance thresholds relate to the fiscal year in which the award is granted, and if and to the extent that such performance thresholds are met, the awards vest in equal one-third (1/3) annual installments.  Until the Company has determined that performance thresholds have been met, the amount of expense that the Company records relating to performance-based awards is estimated based on the likelihood of achieving the performance thresholds.  The amount of expense recorded by the Company is also based on estimated forfeitures.  The fair value of stock-based awards, adjusted for estimated forfeitures (and adjusted for estimated or actual achievement of performance thresholds in the case of awards having performance-based vesting conditions), is amortized using the straight-line attribution method over the requisite service period of the award, which is generally the vesting period.
Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes.  Actual results could differ from those estimates.  Significant estimates made in preparing the consolidated financial statements include (but are not limited to) those related to revenue recognition, the allowance for doubtful accounts, inventory reserves, warranty obligations, pension plans, asset impairment valuations, income tax valuations, and stock-based compensation expenses.
Recent Accounting Pronouncements
In February 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2013-02, Comprehensive Income: Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which requires companies to disclose significant amounts that have been reclassified out of accumulated other comprehensive income.  Amounts that are required to be reclassified in their entirety to net income must be disclosed either on the face of the income statement or in the notes to the financial statements.  Amounts that are not required to be reclassified in their entirety to net income in the same reporting period must be disclosed by a cross reference to other disclosures that provide additional information regarding such amounts.  ASU No. 2013-02 is effective for fiscal years and interim periods beginning after December 15, 2012.  The adoption of ASU No. 2013-02 has not had a material impact on the Company’s financial position or results of operations.
In March 2013, the FASB issued ASU No. 2013-05, Foreign Currency Matters: Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity, which clarifies the guidance in Topics 810 and 830.  Topic 810 requires companies to deconsolidate a subsidiary or derecognize a group of assets if the parent ceases to hold a controlling financial interest in that subsidiary or group of assets.  Upon the loss of a controlling financial interest, the parent would recognize the cumulative translation adjustment in net income.  The guidance in Topic 810 does not distinguish between a sale or transfer of an investment in a foreign entity and a sale or transfer of a subsidiary or group of assets within a foreign entity.  Topic 830 requires the release of the cumulative translation adjustment into net income if a sale or transfer represented a complete or substantially complete liquidation of an investment in a foreign entity.  ASU No. 2013-05 clarifies that companies that cease to have a controlling financial interest in a subsidiary or group of assets within a foreign subsidiary should release the cumulative translation adjustment into net income if the sale or transfer results in a complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided.  ASU No. 2013-05 has become effective for fiscal years beginning after December 15, 2013.  The adoption of ASU No. 2013-05 has not had a material impact on the Company’s financial position or results of operations.
In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which provides explicit guidance on the financial statement presentation of an unrecognized tax benefit.  ASU No. 2013-11 requires unrecognized tax benefits to be presented as a reduction to a deferred tax asset, except that, if a net operating loss carryforward, a similar tax loss or a tax credit carryforward is not available at the reporting date to settle any additional income taxes that would result from the disallowance of a tax position, then the unrecognized tax benefit should be presented as a liability.  ASU No. 2013-11 has become effective for fiscal years and interim periods beginning after December 15, 2013.  The adoption of ASU No. 2013-11 has not had a material impact on the Company’s financial position or results of operations.

	NOTE 2                         ACQUISITIONS AND DIVESTITURES
	Divestiture of Advanced Packaging Systems Business
	During the third quarter of 2013, the Company developed a plan to sell its advanced packaging systems business and, based on negotiations for the sale of this business that occurred during the second half of 2013, the Company considered the assets and liabilities of this business as held for sale as of December 28, 2013.  The Company completed the sale of this business in January 2014 for a price of $6.0 million, consisting of $5.35 million in cash and an unsecured note receivable of $0.65 million.  The Company incurred $0.4 million in transaction costs.  The net book value of this business was $9.5 million as of December 28, 2013; however, because these assets were held for sale at such time, the Company wrote them down to their net realizable value as of December 28, 2013 based on the terms that had been negotiated with the purchaser and expected transaction costs, resulting in a loss of $4.7 million during 2013.  The net sales, operating income and cash flows of this business were not significant to the operations of the Company.
	Acquisition of Vistek Assets
	On October 10, 2012, the Company acquired substantially all of the assets of Advanced Vibration Technologies, Inc., a corporation doing business under the trade name of Vistek (Vistek), for a purchase price of $2.5 million.  The purchase price was paid in cash at closing, of which $0.25 million was deposited at closing into escrow until October 10, 2013, to secure certain indemnification obligations of Vistek and its sole shareholder under the asset purchase agreement.  The full amount of the escrow deposit was released to the seller upon the expiration of the escrow.  The Company incurred $49 thousand in transaction costs, which have been expensed as incurred and are included in selling, general and administrative expenses in the accompanying consolidated statements of operations and comprehensive income (loss).  This acquisition expanded the Company’s vibration control and isolation product offerings.  The results of the Vistek business are included in the results of the Company’s Photonics Group (previously part of the Company’s PPT Division).
	Acquisition of ILX
	On January 13, 2012, the Company acquired all of the outstanding capital stock of ILX Lightwave Corporation (ILX) by means of a merger of a wholly owned subsidiary of the Company with and into ILX.  The total purchase price for the acquisition was $9.0 million.  An initial purchase price of $9.3 million was paid in cash at closing, of which $1.2 million was deposited at closing into escrow until July 12, 2013, to secure certain indemnification and other obligations of the ILX securityholders.  The purchase price was subsequently reduced by $0.3 million, based on a calculation of ILX’s net assets at closing.  The full amount of the escrow deposit was released to the ILX securityholders upon the expiration of the escrow.  The Company incurred $0.1 million in transaction costs, which have been expensed as incurred and are included in selling, general and administrative expenses in the accompanying consolidated statements of operations and comprehensive income (loss).  This acquisition expanded the Company’s optical power meter, laser diode instrumentation and fiber optic source product offerings, and added laser diode and light emitting diode (LED) burn-in, test and characterization systems to its product portfolio.  The results of ILX are included in the results of the Company’s Photonics Group (previously part of the Company’s PPT Division).
	Purchase Price Allocation for 2012 Acquisitions
	The consideration paid by the Company for its acquisitions is allocated to the assets acquired, net of the liabilities assumed, based upon their estimated fair values as of the date of the acquisition.  The estimated fair values of intangible assets acquired were determined using an income approach.  The excess of the purchase price over the estimated fair value of the assets acquired, net of the estimated fair value of the liabilities assumed, is recorded as goodwill.  Below is a summary of the purchase price, assets acquired and liabilities assumed:
	(In thousands)	ILX			Vistek			Total
					Business
	Assets acquired and liabilities assumed:
	Cash	$	44		$	—		$	44

	Other liabilities	(644		)	—			(644		)
		$	8,983		$	2,500		$	11,483
	The goodwill related to the Company’s acquisitions of ILX and Vistek had originally been allocated to the Company’s former PPT Division.  However, as a result of the reorganization of the Company’s operating segments, as discussed in Notes 1 and 15, the goodwill allocated to the Company’s former PPT Division has been reallocated to its Photonics and Optics Groups.  See Note 5 for additional detail regarding this reallocation.  The goodwill related to the Company’s acquisition of ILX is not deductible for tax purposes, as the transaction was a merger.  The goodwill related to the Company’s acquisition of the Vistek business is deductible for tax purposes, as the transaction was an asset purchase.
	Acquisition of Opticoat Assets
	On December 29, 2011, the Company acquired substantially all of the assets of Opticoat SRL (Opticoat) for a purchase price of $3.0 million in cash, of which $2.0 million was paid upon the closing and $1.0 million was held back to secure certain obligations of Opticoat under the acquisition agreement.  The Company paid $0.85 million in 2012 and the remaining $0.15 million in 2013.  The present value of these payments was determined to be $2.9 million.  The Company incurred $0.1 million in transaction costs, which have been expensed as incurred and are included in selling, general and administrative expenses in the accompanying statements of operations and comprehensive income (loss).  This acquisition provided the Company with additional low-cost manufacturing capacity in the areas of precision optical components and coatings.
	Acquisition of Ophir
	On October 4, 2011, the Company acquired all of the outstanding capital stock of Ophir for $242.3 million in cash, of which $242.1 million was allocated to the purchase price and $0.2 million was allocated to the fair value of unearned compensation related to unvested stock options.  The Company funded the purchase price with a combination of $162.8 million of cash on hand and $79.5 million of the net proceeds received from the senior secured credit facility obtained by the Company in October 2011.  After considering the cash held by Ophir as of the closing date, the net cash used by the Company for this transaction was $219.2 million.  The Company incurred $4.7 million in transaction costs, which have been expensed as incurred and are included in selling, general and administrative expenses in the accompanying statements of operations and comprehensive income (loss).  This acquisition added Ophir’s precision infrared optics, laser measurement instrumentation and three-dimensional non-contact measurement sensors and equipment to the Company’s product offerings.
	Acquisition of High Q
	On July 29, 2011, the Company acquired all of the capital stock of High Q Technologies GmbH (High Q).  The total purchase price was $18.5 million, consisting of an initial purchase price of $17.2 million, $2.9 million of which was deposited into escrow until December 31, 2013 to secure representations and warranties made by the sellers, and a subsequent payment of $1.3 million, which was paid to the sellers based on a calculation of High Q’s net assets at closing.  The full amount of the escrow deposit was released to the sellers upon the expiration of the escrow.  After considering the cash held by High Q as of the closing date, the net cash used by the Company for this transaction was $12.5 million.  The Company incurred $0.4 million in transaction costs, which have been expensed as incurred and are included in selling, general and administrative expenses in the accompanying statements of operations and comprehensive income (loss).  This acquisition broadened the Company’s ultrafast laser capabilities, particularly for applications in the life and health sciences and industrial markets, and expanded the Company’s presence in European laser markets.
	Prior to the closing of the acquisition, High Q sold the building that houses its corporate headquarters and its operations to a company established by the then-largest shareholder of High Q for €3.5 million, and leased the building from the purchaser for a period of at least ten years.  High Q financed the purchase price of the building pursuant to a loan agreement with the purchaser that is secured by a mortgage on the building in favor of High Q.  Such loan will be repaid over ten years and accrues interest at an annual rate of 2.0%.  The principal balance of the loan was €3.1 million ($4.2 million) as of December 28, 2013.  As of December 28, 2013, the current portion of the loan was $0.3 million and is included in prepaid expenses and other current assets and the long-term portion of the loan was $3.9 million and is included in investments and other assets.

	For the Company’s Ophir and Opticoat acquisitions, goodwill had been allocated to the Company’s former Ophir Division.  However, in 2012, the Company determined that such goodwill was impaired, as discussed below and in Note 5.  For the Company’s High Q acquisition, goodwill has been allocated to the Company’s Lasers Group, a portion of which will be deductible for Austrian tax purposes.
	In 2012, the Company determined that goodwill and other assets related to its former Ophir Division were impaired and recorded impairment charges of $67.8 million related to goodwill, $62.6 million related to other acquired intangible assets and $0.5 million related to fixed assets.  See Note 5 for additional information.

	As discussed in Note 1, the Company reorganized its operations in January 2013 to create three new operating groups: its Photonics Group, its Lasers Group and its Optics Group.  The Lasers Group is substantially the same as the former Lasers Division.  The Photonics Group is comprised primarily of the photonics products and technologies of the Company’s former PPT Division and the Company’s former Ophir Division.  The Optics Group is comprised primarily of the optical components and integrated solutions products and technologies of the former PPT Division and the former Ophir Division.  The goodwill, and the related impairment of goodwill, of the Company’s former Ophir Division was allocated to the Photonics Group and the Optics Group based on the relative fair values of the new operating groups as of the reorganization date.  The result was a 70% allocation of goodwill to the Photonics Group and a 30% allocation to the Optics Group.  The prior period amounts stated in the table above have been reclassified using these allocation percentages for comparative purposes.
	During 2013, the Company allocated $1.0 million of goodwill to its advanced packaging systems business, which was sold in January 2014, as discussed in Note 2.
	During 2012, the Company allocated $4.0 million of goodwill to the acquisition of ILX and the Vistek business.  These amounts have been reallocated to our Photonics and Optics Groups, as shown in the table above.
	During 2012, sales by the Company’s former Ophir Division were below the levels that it had originally forecasted at the time of the acquisition of Ophir.  In light of those sales levels and other factors, in connection with the annual evaluation of goodwill and other intangible assets in the fourth quarter of 2012, the Company determined that the cash flow projections of its former Ophir Division had diminished and, therefore, the goodwill and other intangible assets associated with that division were impaired.  As a result, the Company recorded an impairment charge of $67.8 million, which has been reallocated to our Photonics and Optics Groups, as shown in the table above.
	Intangible assets, excluding goodwill, were as follows:
		December 28,			December 29,

	Trademarks and trade names	18,305			18,305
	Intangible assets, net	$	67,342		$	77,446
	As discussed above, during 2012, the Company determined that intangible assets associated with its former Ophir Division were impaired.  As a result, the Company recorded an impairment charge related to acquired intangible assets of $62.6 million.  Such charges consisted of $33.8 million for customer relationships, $21.5 million for developed technology, $2.1 million for in-process research and development, $4.6 million for indefinite-lived trade names and $0.6 million for finite-lived trade names.  Trade names and developed technologies were valued using the relief-from-royalty method, and customer relationships and in-process research and development were valued using the multi-period excess earnings method.
	Amortization expense related to intangible assets totaled $10.3 million, $17.7 million and $7.7 million for 2013, 2012 and 2011, respectively.
	Estimated aggregate amortization expense for future fiscal years will be amortized over a remaining weighted-average life of 10.2 years as follows:

	The Company has excluded $0.6 million of amortization expense related to in-process research and development from the table above, as it was uncertain as of December 28, 2013 when the technology will be completed and when the amortization will begin.

STOCK INCENTIVE PLANS AND STOCK-BASED COMPENSATION	'
	NOTE 7                         STOCK INCENTIVE PLANS AND STOCK-BASED COMPENSATION
	Stock-Based Benefit Plans
	In March 2011, the Company’s Board of Directors adopted the 2011 Stock Incentive Plan (2011 Plan) subject to approval of its stockholders, which was received in May 2011.  The primary purpose of the 2011 Plan is to enhance the Company’s ability to attract, motivate and retain the services of qualified employees, officers and directors, consultants and other service providers upon whose judgment, initiative and efforts the successful conduct and development of the Company’s business largely depends.
	The 2011 Plan authorizes the Company to grant up to 6,000,000 shares of common stock.  This number of shares is subject to adjustments as to the number and kind of shares in the event of stock splits, stock dividends or certain other similar changes in the capital structure of the Company.  Upon approval of the 2011 Plan by the Company’s stockholders, the Company’s 2006 Performance-Based Stock Incentive Plan was terminated for purposes of future grants, and only the 6,000,000 shares authorized for issuance under the 2011 Plan remained available for future grants.
	The 2011 Plan permits the grant of stock appreciation rights, restricted stock, restricted stock units, incentive stock options and non-qualified stock options.  For purposes of calculating the total number of shares that may be issued under the 2011 Plan, the 2011 Plan provides that “full value” awards shall be counted against the share limit to a greater extent than “appreciation” awards.  Stock options and stock appreciation rights, which are “appreciation” awards, shall be counted against the share limit under the 2011 Plan as one (1) share for each share of common stock subject to such award.  Restricted stock and restricted stock units, which are “full value” awards, shall be counted against the share limit under the 2011 Plan as one and seven tenths (1.7) shares for each share of common stock subject to such award.
	Any stock options or stock appreciation rights granted under the 2011 Plan will have exercise prices or base values not less than the fair market value of the Company’s common stock on the date of grant and terms of not more than seven years.  The vesting of substantially all awards granted to directors under the 2011 Plan occurs over a period of one year.  The vesting of substantially all awards granted to officers and employees under the 2011 Plan occurs over a period of three years, and the vesting of substantially all restricted stock unit awards is also conditioned upon the achievement of performance thresholds established by the Compensation Committee of the Company’s Board of Directors.  Currently, such performance thresholds relate to the fiscal year in which the award is granted, and if and to the extent that such performance thresholds are met, the awards vest in equal one-third (1/3) annual installments.  All awards are subject to forfeiture if employment or other service terminates prior to the vesting of the awards.
	The Company maintains an Employee Stock Purchase Plan (Purchase Plan) to provide employees of the Company with an opportunity to purchase common stock through payroll deductions.  The Purchase Plan allows employees to purchase common stock in any quarterly offering period at 95% of the fair market value of the stock on the last day of the offering period.
	Stock-Based Compensation Expense
	ASC 718 requires the Company to recognize compensation expense related to the fair value of its stock-based awards.  The Company estimates the fair value of stock options and stock appreciation rights at the date of grant using a Black-Scholes-Merton option-pricing model.  The weighted average fair value and underlying assumptions for all stock appreciation rights are set forth in the table below.  No stock options were granted during the periods presented.

	Research and development expense	1,093			936			684
		$	9,173		$	8,369		$	6,201
	As required by ASC 718, the Company estimates the expected future forfeitures of stock options, stock appreciation rights and restricted stock units and recognizes compensation expense for only those equity awards expected to vest, excluding the expected future forfeitures.  If actual forfeitures differ from the Company’s estimates, the amount of compensation expense recognized for the applicable period is cumulatively adjusted.  The Company assumed forfeiture rates of 12.5%, 12.5% and 15.4% in recognizing compensation expense for 2013, 2012 and 2011, respectively.
	At December 28, 2013, the total compensation cost related to unvested stock-based awards granted to employees, officers and directors under the Company’s stock-based benefit plans that had not yet been recognized was $15.8 million, net of estimated forfeitures.  This future compensation expense will be amortized, using the straight-line attribution method over a weighted-average period of 1.9 years.  The actual compensation expense that the Company will recognize in the future related to stock-based awards outstanding at December 28, 2013 will be adjusted for subsequent forfeitures.  All performance conditions applicable to stock-based awards outstanding at December 28, 2013 have been met.

	Secured Credit Facility
	In October 2011, the Company entered into a credit agreement with certain lenders.  Such credit agreement and the related security agreement provided for a senior secured credit facility consisting of a $185 million term loan and a $65 million revolving line of credit, each with a term of five years.
	On July 18, 2013, the Company entered into a new credit agreement with certain lenders (New Credit Agreement), which replaced the Company’s prior credit agreement.  The New Credit Agreement consists of a senior secured revolving credit facility of $275 million with a term of five years (New Credit Facility).  The New Credit Agreement also provides the Company with the option to increase the aggregate principal amount of loans in the form of additional revolving loans or a separate tranche of term loans, in an aggregate amount that does not exceed $50 million, in each case subject to certain terms and conditions contained in the New Credit Agreement.  Concurrently with the closing of the New Credit Agreement, the Company terminated the prior credit agreement after repaying the entire outstanding principal amount of $152.6 million and all accrued interest and fees thereon, utilizing $120.0 million borrowed under the New Credit Facility together with a portion of the Company’s then-existing cash balances.  Upon terminating the prior credit agreement, the Company recorded a loss on extinguishment of debt of $3.4 million, to write off the remaining deferred debt issuance costs relating to the prior credit agreement.
	At December 28, 2013, the outstanding balance under the New Credit Facility was $83.0 million.  The interest rate per annum applicable to amounts outstanding under the New Credit Facility is, at the Company’s option, either (a) the base rate as defined in the New Credit Agreement (Base Rate) plus an applicable margin, or (b) the Eurodollar Rate as defined in the New Credit Agreement (Eurodollar Rate) plus an applicable margin.  A commitment fee is payable on the unused portion of the New Credit Facility.  The margins over the Base Rate and Eurodollar Rate applicable to the loans outstanding under the New Credit Facility, and the commitment fee, are adjusted periodically based on the consolidated leverage ratio of the Company, as calculated pursuant to the New Credit Agreement.  The maximum applicable margins are 1.25% per annum for Base Rate loans and 2.25% per annum for Eurodollar Rate loans, and the minimum applicable margins are 0.5% per annum for Base Rate loans and 1.5% per annum for Eurodollar Rate loans.  The maximum commitment fee is 0.40% per annum, and the minimum commitment fee is 0.25% per annum.  As of December 28, 2013, the interest rate per annum applicable to amounts outstanding under the New Credit Facility was 1.94%, and the commitment fee on the unused portion of the New Credit Facility was 0.30%.
	The Company’s obligations under the New Credit Agreement are secured by a lien on substantially all of the assets of Newport Corporation and certain of its U.S. subsidiaries, which are guarantors under the New Credit Agreement, as well as by a pledge of certain shares of international subsidiaries of Newport Corporation.
	Other Loans
	As part of the acquisition of Ophir, the Company assumed certain loans with Israeli and Japanese banks.  The effective interest rates and the principal amounts outstanding under these loans at December 28, 2013 are shown in the table above.  The loans in Japan are generally unsecured, and the loans in Israel are generally secured by pledges of and liens on certain of Ophir’s assets.

	NOTE 10                  COMMITMENTS AND CONTINGENCIES
	Facility Leases
	The Company leases certain of its manufacturing and office facilities and equipment under non-cancelable leases, certain of which contain renewal options.  In addition to the base rent, the Company is generally required to pay insurance, real estate taxes and other operating expenses relating to such facilities.  In some cases, base rent increases during the term of the lease based on a predetermined schedule.  The Company recognizes rent expense on a straight-line basis over the life of the lease for leases containing stated rent escalations.
	Future minimum rental commitments under the terms of these leases at December 28, 2013 were as follows:
		Capital			Operating		Total
	(In thousands)	Leases			Leases		Obligations

	Rental expense, net of sublease income, under all leases totaled $11.5 million, $10.6 million and $9.1 million for 2013, 2012 and 2011, respectively.
	Environmental Reserves
	The Company’s former Mountain View, California facility is an EPA-designated Superfund site and is subject to a cleanup and abatement order from the California Regional Water Quality Control Board.  Spectra-Physics, along with several other entities with facilities located near the Mountain View, California facility, have been identified as Responsible Parties with respect to this Superfund site, due to releases of hazardous substances during the 1960s and 1970s.  The site is mature, and investigations and remediation efforts have been ongoing for approximately 30 years.  Spectra-Physics and the other Responsible Parties have entered into a cost-sharing agreement covering the costs of remediating the off-site groundwater contamination, pursuant to which Spectra-Physics is responsible for 30% of the remediation costs.
	At the time of the Company’s acquisition of Spectra-Physics, it established a reserve to cover known costs relating to this site for which it was liable, the balance of which was immaterial at December 28, 2013 and December 29, 2012.  In connection with the acquisition, Thermo Fisher Scientific, Inc., formerly known as Thermo Electron Corporation (Spectra-Physics’ former parent) has agreed, subject to certain conditions, to indemnify the Company for certain costs of remediation that are incurred and third party claims that are made prior to July 16, 2014 relating to this site.  Following the expiration of this indemnity, the Company will be responsible for any remediation costs.  However, the Company is currently unaware of any material future expenses associated with this site for which the Company will be liable.
	Indemnification Obligations
	The Company from time to time enters into certain types of agreements that contingently require the Company to indemnify the other parties against certain claims.  These contracts primarily include: (i) contracts for the development and/or sale of products, under which the Company customarily agrees to hold the other party harmless against losses arising from bodily injury or damage to personal property caused by the Company’s personnel or products or infringement by the Company’s products of third-party intellectual property rights; (ii) certain real estate leases, under which the Company may be required to indemnify property owners for environmental and other liabilities, and other claims arising from the Company’s use of the applicable premises; (iii) divestiture agreements, under which the Company may provide customary indemnifications to purchasers of the Company’s businesses or assets; and (iv) certain agreements with the Company’s officers, directors and employees, under which the Company may be required to indemnify such persons for liabilities incurred by them in the course of their employment.
	In each of these circumstances, payment by the Company is typically subject to the other party making a claim to and cooperating with the Company pursuant to the procedures specified in the particular contract. This usually allows the Company to challenge the other party’s claims and to control the defense or settlement of any third-party claims brought against the other party.  The Company’s obligations under these agreements are typically not limited in terms of amount or duration. In some instances, the Company may have recourse against third parties and/or insurance covering certain payments made by the Company.
	It is not possible to predict the maximum potential amount of future payments under these or similar agreements due to the conditional nature of the Company’s obligations and the unique facts and circumstances involved in each particular agreement.  Historically, the Company has not been obligated to make significant payments for these obligations, and no liabilities have been recorded for these obligations as of December 28, 2013 and December 29, 2012.
	Other Contingencies
	In November 2010, two former employees of Spectra-Physics, Linda Pope and Yvette Flores, together with their children, Tia Pope Hudson and Mark Flores, filed a complaint against Spectra-Physics and the Company in the Superior Court for Santa Clara County, California.  Plaintiffs alleged that between 1975 and 1985 they were harmed by exposure to toxic substances at Spectra-Physics, and that Spectra-Physics failed to warn them about dangers associated with the substances and failed to implement adequate safeguards to protect them from the substances.
	In June 2013, the court granted the Company’s motion for summary judgment of Yvette Flores’ claims on the grounds that they were barred by the exclusivity of the State of California’s workers’ compensation system.  In July 2013, the Company reached an agreement with Mark Flores to settle his claims, which were then the only claims remaining in the suit.  In September 2013, the Company entered into a Settlement Agreement and Release with Mark Flores documenting the specifics of the settlement.  The settlement amounts were paid in 2013 from coverage by applicable insurance policies. As such, this settlement did not have any net impact on the Company’s income, cash flows or stockholders’ equity.  An Order of Dismissal was filed in December 2013 with respect to Mark Flores’ claims, ending his case against the Company and Spectra-Physics.
	In November 2012, the Company reached an agreement with Linda Pope and Tia Pope Hudson to settle all claims related to their portion of the suit.  The settlement amount was paid in February 2014 from coverage by applicable insurance policies.  As such, this settlement did not have any net impact on the Company’s income, cash flows or stockholders’ equity.  The remainder of the case against the Company and Spectra-Physics was dismissed with prejudice in February 2014.
	From time to time, the Company may be involved in litigation relating to claims arising out of its operations in the normal course of business.  Except as described above, the Company currently is not a party to any other legal proceedings, the adverse outcome of which, in management’s opinion, individually or in the aggregate, would have a material adverse effect on the Company’s results of operations, financial position or cash flows.

		$	5,698		$	5,479		$	(29,154	)
	Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the deferred taxes were as follows:
		December 28,			December 29,
	(In thousands)	2013			2012
	Deferred tax assets:
	Net operating loss carryforwards	$	2,438		$	4,711
	Accruals and reserves not currently deductible	18,340			19,199
	Tax credit carryforwards	1,769			1,633
	Other basis differences	9,029			7,511
	Total gross deferred tax assets	31,576			33,054

		29,314			29,919
	Deferred tax liabilities:
	Intangible assets	14,025			17,011
	Property and equipment	3,402			4,446
	Other basis differences	463			368
	Total deferred tax liabilities	17,890			21,825
	Net deferred tax assets	$	11,424		$	8,094
	In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized.  The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible.  Management considers taxable income in carryback years, the scheduled reversal of deferred tax liabilities (exclusive of deferred tax liabilities related to indefinite lived intangibles), tax planning strategies and projected future taxable income in making this assessment.
	The Company had previously established a valuation allowance against substantially all domestic and certain foreign deferred tax assets due to the uncertainty as to the timing and ultimate realization of those assets.  During the fourth quarter of 2011, the Company achieved a cumulative three-year income position in the United States.  Management considered this position along with other available evidence, both positive and negative, and determined, as of December 31, 2011, that it was more likely than not that the net deferred tax assets (exclusive of deferred tax liabilities related to indefinite lived intangibles) would be realized, with the exception of domestic capital losses, domestic unrealized losses, foreign net operating loss carryforwards and other miscellaneous foreign deferred tax assets. Accordingly, the Company recorded a reduction in the valuation allowance of $41.7 million.  During 2012, the Company released $1.8 million of its valuation allowance related to certain domestic deferred tax assets due to the recovery of certain investments and capital loss carryovers.  Also during 2012, after evaluating all positive and negative facts, the Company determined that it was not more likely than not that the Company would realize certain deferred tax assets associated with its former Ophir Division.  Therefore, the Company recorded a valuation allowance of $1.9 million, substantially all of which was applicable to the Optical Metrology Ltd. subsidiary based in Jerusalem, Israel.  In 2013, the Company reduced its valuation allowance by $0.9 million, due primarily to Optical Metrology Ltd. qualifying for the beneficial tax rate of 0% on a portion of its earnings, which necessitated an adjustment to the underlying deferred tax assets and a corresponding adjustment to the valuation allowance.
	As of December 28, 2013, the Company could not determine that it is more likely than not that deferred tax assets related to domestic unrealized losses, certain domestic and foreign net operating loss carryforwards and other miscellaneous foreign deferred tax assets would be realized.  Therefore, the Company has maintained a valuation allowance of $2.3 million against its domestic and certain foreign subsidiaries’ deferred tax assets.
	At December 28, 2013, the Company had gross state and foreign net operating loss carryforwards totaling approximately $32.7 million and $10.2 million, respectively.  State net operating loss carryforwards begin to expire in 2015, Romania net operating losses begin to expire in 2019, and a majority of the remaining foreign net operating loss carryforwards may be carried forward indefinitely.
	At December 28, 2013, the Company had federal and state income tax credit carryforwards of $19.8 million and $11.2 million, respectively.  Certain unused federal carryforwards will begin to expire in 2016 and will continue to expire in future years if not fully utilized.  The state carryforwards do not expire.
	On September 13, 2013, the U.S. Treasury Department released final income tax regulations on the deduction and capitalization of expenditures related to tangible property.  These final regulations apply to tax years beginning on or after January 1, 2014.  Several of the provisions within the regulations will require a tax accounting method change to be filed with the Internal Revenue Service, however, the Company does not anticipate the impact of these changes to be material to its financial position or results of operations.
	The Company recognizes excess tax benefits associated with share-based compensation to stockholders’ equity only when realized.  When assessing whether excess tax benefits relating to share-based compensation have been realized, the Company follows the with-and-without approach excluding any indirect effects of the excess tax deductions.  Under this approach, excess tax benefits related to share-based compensation are not deemed to be realized until after the utilization of all other tax benefits available to the Company.  During the year ended December 28, 2013, the Company realized approximately $4.0 million of such excess tax benefits and, accordingly, recorded a corresponding increase in capital in excess of par value.  As of December 28, 2013, the Company had $17.5 million of unrealized excess tax benefits associated with share-based compensation.  These tax benefits, if and when realized, will be accounted for as an increase in capital in excess of par value rather than as a reduction in the provision for income taxes.
	If the Company has an “ownership change” as defined under the Internal Revenue Code, utilization of its net operating loss and tax credit carryforwards may be subject to an annual limitation against taxable income in future periods.
Undistributed earnings of the Company’s historic and acquired foreign subsidiaries for which no federal or state liability has been recorded totaled $32.9 million and $22.6 million at December 28, 2013 and December 29, 2012, respectively.  These undistributed earnings are considered to be indefinitely reinvested.  Accordingly, no provision for federal and state income taxes or foreign withholding taxes has been provided on such undistributed earnings. Determination of the potential amount of unrecognized deferred federal and state income tax liability and foreign withholding taxes is not practicable because of the complexities associated with this hypothetical calculation; however, unrecognized foreign tax credits would be available to reduce some portion of the federal liability.
As of December 29, 2012, the Company had $15.2 million of gross unrecognized tax benefits and a total of $12.4 million of net unrecognized tax benefits, which, if recognized, would affect the effective tax rate.  Interest and penalties related to unrecognized tax benefits were not significant as of December 29, 2012.
As of December 28, 2013, the Company had $17.4 million of gross unrecognized tax benefits and a total of $14.4 million of net unrecognized tax benefits, which, if recognized, would affect the effective tax rate.  Interest and penalties related to unrecognized tax benefits were not significant as of December 28, 2013.  The Company does not anticipate that its unrecognized tax benefits will change significantly over the next twelve months.
A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows:
	Year Ended
	December 28,			December 29,			December 31,
(In thousands)	2013			2012			2011

Unrecognized tax benefits at end of year	$	17,429		$	15,173		$	17,735
The Company and its subsidiaries file income tax returns in the United States and various state, local and foreign jurisdictions.  The tax years that remain subject to examination by significant jurisdiction are as follows:
U.S. Federal	2010 through current periods
California	2009 through current periods
France	2011 through current periods
Germany	2010 through current periods
Japan	2007 through current periods
Israel	2008 through current periods
However, the use of domestic net operating losses in future periods could trigger a review of attributes and other tax matters in years that are not otherwise subject to examination, beginning with the 2002 tax year.

	NOTE 14                  EMPLOYEE BENEFIT PLANS
	Defined Contribution Plan
	The Company sponsors certain 401(k) defined contribution plans.  Generally, all U.S. employees are eligible to participate in and contribute to one of these plans.  The Company makes certain matching contributions to these plans based on participating employees’ contributions to the plans and their total compensation.  Expense recognized for the plans totaled $4.8 million, $4.8 million and $4.9 million for 2013, 2012 and 2011, respectively.
	Defined Benefit Pension Plans
	The Company has defined benefit pension plans covering substantially all full-time employees in France, Germany, Israel and Japan.  In addition, the Company has certain pension liabilities relating to former employees of the Company 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.
	December 28, 2013, December 29, 2012 and December 31, 2011 serve as the measurement dates for the respective amounts shown below.  Net periodic benefit costs for the plans in aggregate included the following components:

	At December 28, 2013 and December 29, 2012, the United Kingdom plan was overfunded and had assets of $3.3 million and $3.3 million, respectively, and a projected benefit obligation of $3.1 million and $3.0 million, respectively.  The Company’s Israeli plans account for the deferred vested benefits using the shut-down method of accounting, which resulted in assets of $11.5 million and $10.7 million and vested benefit obligations of $12.8 million and $12.2 million being reported on a gross basis as of December 28, 2013 and December 29, 2012, respectively.  Under the shut-down method, the liability is calculated as if it was payable as of each balance sheet date, on an undiscounted basis.  All other plans were underfunded and had combined assets of $5.9 million and $6.1 million at December 28, 2013 and December 29, 2012, respectively, and combined projected benefit obligations of $20.6 million and $21.9 million at December 28, 2013 and December 29, 2012, respectively.
	At December 28, 2013, the aggregate projected benefit obligations, accumulated benefit obligations and fair value of plan assets were $36.4 million, $33.7 million and $9.2 million, respectively.  At December 29, 2012, the aggregate projected benefit obligations, accumulated benefit obligations and fair value of plan assets were $37.2 million, $33.8 million and $9.4 million, respectively.
	At December 28, 2013, the estimated benefit payments for the next 10 years were as follows:
		Estimated
		Benefit
	(In thousands)	Payments
	2014	$	1,671
	2015	1,309
	2016	2,597
	2017	1,213
	2018	1,177
	2019-2024	22,939
		$	30,906
The Company expects to contribute $1.8 million to the plans during 2014.
The weighted-average rates used to determine the net periodic benefit costs were as follows:
	December 28,		December 29,		December 31,
	2013		2012		2011
Discount rate	1.87	%	2.29	%	2.44	%
Rate of increase in salary levels	1.67	%	2.38	%	2.25	%
Expected long-term rate of return on assets	1.89	%	1.59	%	1.59	%
The weighted-average rates used to determine projected benefit obligations for the respective periods were as follows:
	December 28,		December 29,
	2013		2012
Discount rate	1.96	%	1.87	%
Rate of increase in salary levels	1.58	%	1.67	%
Expected long-term rate of return on assets	1.83	%	1.89	%
In determining the expected long-term rate of return on plan assets, the Company considers the relative weighting of plan assets, the historical performance of total plan assets and individual asset classes, and economic and other indicators of future performance.
Plan assets were held in the following categories as a percentage of total plan assets:
	December 28, 2013					December 29, 2012
(Amounts in thousands)	Amount			Percentage		Amount			Percentage
Cash	$	575		6	%	$	2,249		24	%
Bonds	1,256			13		1,410			15
Equity securities	1,429			16		—			—
Insurance contracts	5,938			65		5,761			61
	$	9,198		100	%	$	9,420		100	%
In general, the Company’s asset management objectives include maintaining an adequate level of diversification to reduce interest rate and market risk while providing adequate liquidity to meet immediate and future benefit payment requirements.  In Japan, assets are primarily invested in pooled funds of insurance companies.  The expected long-term rate of return on these assets is 1.5%, which is based on the general yield environment for high quality instruments in Japan.  The United Kingdom pension plan invests in a combination of equity and bond funds.  The allocation mix is designed to minimize risk while providing a rate of return that will provide asset growth which will be sufficient to cover expected liabilities.  The expected long-term rate of return on these assets is 2.7%, which is based on bank base rates.  In France, assets are invested in group insurance contracts and the expected long-term rate of return on these assets is 1.2%, which is based on the expected return on the underlying assets.  The Company does not invest in derivative instruments, although the pooled funds it owns may use such instruments in a risk management capacity.
Other Pension-Related Assets
As of December 28, 2013 and December 29, 2012, the Company had assets with an aggregate market value of $6.9 million and $6.6 million, respectively, which it has set aside in connection with its German pension plans.  These assets are invested in group insurance contracts through the insurance companies administering these plans, in accordance with applicable pension laws.  The German contracts have a guaranteed minimum rate of return ranging from 2.25% to 4.0%, depending on the contract.  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.  Such assets are included in investments and other assets in the accompanying consolidated balance sheets.
The Company’s Israeli plans are accounted for using the shut-down method of accounting.  As a result, plan assets are reported separate from the net underfunded pension liability and were not included in the Company’s plan assets shown above.  The Israeli assets are invested in government regulated pension funds, which invest primarily in bonds.  As of December 28, 2013 and December 29, 2012, the aggregate market value of these assets was $11.5 million and $10.7 million, respectively.  Such assets are included in investments and other assets in the accompanying consolidated balance sheets.
Fair Value Measurements
The carrying amount of cash and cash equivalents approximates fair value due to the short-term maturities of these instruments.  The fair value of bond funds is based on quoted prices provided by the fund issuer and the fair value of insurance contracts is based on quoted prices provided by the insurance provider.  Because the bond funds and insurance contracts are not actively traded but are valued using observable inputs, they fall within Level 2 of the fair value hierarchy.  Equity securities are included within an equity fund and the fair value is based on quoted prices provided by the fund issuer.  Although the individual equity securities are actively traded, the fund is not publicly traded, therefore, these assets fall within Level 2 of the fair value hierarchy.

BUSINESS SEGMENT INFORMATION	'
	NOTE 15                  BUSINESS SEGMENT INFORMATION
	The operating segments reported herein are the segments of the Company for which separate financial information was available and for which operating results were evaluated regularly by the Company’s Chief Executive Officer, who is the Company’s chief operating decision maker, in deciding how to allocate resources and in assessing performance, during the periods covered by the accompanying financial statements.
	As discussed above, prior to 2013, the Company developed, manufactured and marketed its products within three distinct business segments: its Lasers Division, its PPT Division and its Ophir Division.  In January 2013, the Company reorganized its operations to create three new operating segments: its Photonics Group, its Lasers Group and its Optics Group.  As a result, the Company has revised its reportable segments to correspond with its new operating segments, reflecting the manner in which it now assesses performance and allocates resources.  The results of operations of the Company’s reportable segments for 2012 and 2011 reported below have been restated to conform to the new reportable segments.
	The Photonics Group products are sold to end-user customers in a wide range of markets, including the microelectronics, scientific research, defense and security, life and health sciences and industrial markets.  The products sold by this group include photonics instruments and systems, precision positioning systems and subsystems, vibration isolation systems and subsystems, optical components for research applications, optical hardware and three-dimensional non-contact measurement sensors and equipment.
	The Lasers Group offers a broad array of laser technology products and services to OEM and end-user customers across a wide range of applications and markets, including the microelectronics, scientific research, life and health sciences and industrial markets.  The lasers and laser-based systems include ultrafast lasers and amplifiers, diode-pumped solid-state lasers, high-energy pulsed lasers, tunable lasers, fiber lasers and gas lasers.
	The Optics Group products and systems are sold to end-user customers in a wide range of markets, including the microelectronics, defense and security, life and health sciences and industrial markets.  The products sold by this group include precision optics and lens assemblies, optical components and opto-mechanical subassemblies.  In addition, this group sells subsystems to customers that integrate these products into larger systems, particularly for microelectronics and life and health sciences applications.
	The Company measured income reported for each operating segment, which included only those costs that were directly attributable to the operations of that segment, and excluded unallocated operating expenses, such as corporate overhead and intangible asset amortization, certain gains and losses, interest and other expense, net, and income taxes.
	Selected segment financial information for the Company’s reportable segments for the years ended December 28, 2013, December 29, 2012 and December 31, 2011 were as follows:

ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'
Basis of Presentation	'
	Basis of Presentation
	The accompanying financial statements include the accounts of Newport Corporation and its wholly owned and majority owned subsidiaries.  All intercompany transactions and balances have been eliminated in consolidation.
	The Company uses a 52/53-week accounting fiscal year ending on the Saturday closest to December 31, and its fiscal quarters end on the Saturday that is generally closest to the end of each corresponding calendar quarter.  Fiscal year 2013 (referred to herein as 2013) ended on December 28, 2013, fiscal year 2012 (referred to herein as 2012) ended December 29, 2012 and fiscal year 2011 (referred to herein as 2011) ended December 31, 2011.  Each of these fiscal years consisted of 52 weeks.
Foreign Currency Translation	'
	Foreign Currency Translation
	Assets and liabilities for the Company’s international operations are translated into U.S. dollars using current rates of exchange in effect at the balance sheet dates.  Items of income and expense for the Company’s international operations are translated using the monthly average exchange rates in effect for the period in which the items occur.  The functional currency for all of the Company’s international operations is the local currency, except for Israel and Canada, for which the functional currency is the U.S. dollar.  Where the local currency is the functional currency, the resulting translation gains and losses are included as a component of stockholders’ equity in accumulated other comprehensive income (loss).  Where the U.S. dollar is the functional currency, the resulting translation gains and losses are included in the results of operations.  Realized foreign currency transaction gains and losses for all entities are included in the results of operations.
Derivative Instruments	'
	Derivative Instruments
	The Company recognizes all derivative financial instruments in the consolidated financial statements at fair value regardless of the purpose or intent for holding the instrument.  The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and further, on the type of hedging relationship.  The Company does not engage in currency speculation; however, the Company uses forward exchange contracts and foreign currency option contracts to mitigate the risks associated with certain foreign currency transactions entered into in the ordinary course of business, primarily foreign currency denominated receivables and payables.  The Company has not elected hedge accounting treatment and, accordingly, changes in fair values are reported in the consolidated statements of operations and comprehensive income (loss).  The forward exchange contracts and foreign currency option contracts generally result in the Company paying or receiving net amounts, based on the change in foreign currency rates between inception of the contracts and maturity of the contracts.  If the counterparties to the contracts (typically highly rated banks) do not fulfill their obligations to deliver the contracted currencies, the Company could be at risk for any currency related fluctuations.  Changes in fair values and transaction gains and losses are included in interest and other expense, net in the results of operations.  Such amounts were not material for 2013, 2012 or 2011.
Cash and Cash Equivalents and Marketable Securities	'
	Cash and Cash Equivalents and Marketable Securities
	The Company considers cash and highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents.  Investments with original maturities exceeding three months at the date of purchase are classified as marketable securities.  All marketable securities are classified as available for sale and are recorded at market value using the specific identification method; unrealized gains and losses are reflected in accumulated other comprehensive income (loss) unless the Company determines there is an other-than-temporary impairment, in which case the loss is recorded in the consolidated statements of operations and comprehensive income (loss).
Restricted Cash	'
	Restricted Cash
	The Company has certain agreements, which require it to maintain specified cash balances as collateral.  Such amounts have been classified as restricted cash.
Accounts Receivable	'
	Accounts Receivable
	The Company records reserves for specific receivables deemed to be at risk for collection, as well as a reserve based on its historical collections experience. The Company estimates the collectability of customer receivables on an ongoing basis by reviewing past due invoices and assessing the current creditworthiness of each customer.  A considerable amount of judgment is required in assessing the ultimate realization of these receivables.
Concentrations of Credit Risk	'
	Concentrations of Credit Risk
	Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, foreign exchange contracts and accounts receivable.  The Company maintains cash and cash equivalents with and purchases its foreign exchange contracts from major financial institutions and performs periodic evaluations of the relative credit standing of these financial institutions in order to limit the amount of credit exposure with any one institution.  Substantially all of the Company’s marketable securities are currently invested in Euro Over Night Index Average (Eonia) securities or certificates of deposit.  The Company’s senior financial management and the Company’s Board of Directors periodically review the marketable securities to determine the appropriate investment strategy.
	The Company’s customers are concentrated in the scientific research, defense and security, microelectronics, life and health sciences and industrial markets, and their ability to pay may be influenced by the prevailing macroeconomic conditions present in these markets.  Receivables from the Company’s customers are generally unsecured.  To reduce the overall risk of collection, the Company performs ongoing evaluations of its customers’ financial condition.  For the years ended December 28, 2013, December 29, 2012 and December 31, 2011, no customer accounted for 10% or more of the Company’s net sales or 10% or more of the Company’s gross accounts receivable as of the end of such year.
Pension Plans	'
	Pension Plans
	Several of the Company’s non-U.S. subsidiaries have defined benefit pension plans covering substantially all full-time employees at those subsidiaries.  Some of the plans are unfunded, as permitted under the plans and applicable laws.  For financial reporting purposes, the calculation of net periodic pension costs is 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 are based upon management’s judgment, considering all known trends and uncertainties.
	The Company accounts for its Israeli pension plans 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.  In addition, the assets and liabilities of the plans are accounted for on a gross basis.
Inventories	'
	Inventories
	Inventories are stated at the lower of cost (determined on a first-in, first-out (FIFO) basis) or fair market value and include materials, labor and manufacturing overhead.  Inventories that are expected to be sold within one year are classified as current inventories and are included in inventories, and inventories that the Company expects to hold for longer than one year are included in investments and other assets.  The Company writes down excess and obsolete inventory to net realizable value.  Once the Company writes down the carrying value of inventory, a new cost basis is established, and the Company does not increase the newly established cost basis based on subsequent changes in facts and circumstances.  In assessing the ultimate realization of inventories, the Company makes judgments as to future demand requirements and compares those requirements with the current or committed inventory levels.  The Company records any amounts required to reduce the carrying value of inventory to net realizable value as a charge to cost of sales.
Property and Equipment	'
	Property and Equipment
	Property and equipment are stated at cost, less accumulated depreciation.  Depreciation expense includes amortization of assets under capital leases.  Depreciation is recorded on a straight-line basis over the estimated useful lives of the assets as follows:
	Buildings and improvements	3 to 40 years
	Machinery and equipment	2 to 20 years
	Office equipment	3 to 10 years
	Leasehold improvements are amortized over the shorter of their estimated useful life or the remaining lease term.
Capitalized Software Costs	'
	Capitalized Software Costs
	All direct costs related to developing internal use software during the application development stage are capitalized and amortized using the straight-line method over the estimated useful lives of the assets.  Costs incurred in the preliminary project stage, maintenance costs and training costs are expensed as incurred.
Intangible Assets, including Goodwill	'
	Intangible Assets, including Goodwill
	Developed technology is amortized on a straight line basis over 10 to 20 years, depending on the life of the product technology.  Intangible assets related to customer relationships are primarily amortized over a period of up to 10 years on an accelerated basis.  In-process research and development is amortized on a straight line basis over the product’s estimated useful life upon completion of the technology.  Other intangible assets include acquired backlog, product trademarks and trade names, non-competition agreements and defensible assets.  With the exception of product trademarks and trade names, such assets are amortized on a straight line basis over a period of three months to 10 years, depending on the asset.  Trademarks and trade names associated with products are amortized on a straight line basis over the estimated remaining life of the product technology, which ranges from 10 to 20 years.  Trademarks and trade names associated with a business have indefinite lives and are not amortized.
	Goodwill represents the excess of the purchase price of the net assets of acquired entities over the fair value of such assets.  Under Accounting Standards Codification (ASC) 350, Intangibles — Goodwill and Other, goodwill and other indefinite-lived intangible assets are not amortized but are tested for impairment at least annually or when circumstances exist that would indicate an impairment of such goodwill or other intangible assets.  The Company performs the annual impairment test as of the beginning of the fourth quarter of each year.  A two-step test is used to identify the potential impairment and to measure the amount of impairment, if any.  The first step is based upon a comparison of the fair value of each of the Company’s reporting units, as defined, and the carrying value of the reporting unit’s net assets, including goodwill.  If the fair value of the reporting unit exceeds its carrying value, goodwill is considered not to be impaired; otherwise, step two is required.  Under step two, the implied fair value of goodwill, calculated as the difference between the fair value of the reporting unit and the fair value of the net assets of the reporting unit, is compared with the carrying value of goodwill.  The excess of the carrying value of goodwill over the implied fair value represents the amount impaired.
	The Company determines its reporting units by identifying those operating segments or components for which discrete financial information is available which is regularly reviewed by the management of that unit.  For any acquisition, the Company allocates goodwill to the applicable reporting unit at the completion of the purchase price allocation through specific identification.
	Fair value of the Company’s reporting units is determined using a combination of a comparative company analysis and a discounted cash flow analysis.  The comparative company analysis establishes fair value by applying market multiples to the Company’s revenue and earnings before interest, income taxes, depreciation and amortization.  Such multiples are determined by comparing the Company’s reporting units with other publicly traded companies within the respective industries that have similar economic characteristics.  In addition, a control premium is added to reflect the value an investor would pay to obtain a controlling interest, which is consistent with the median control premium for transactions in those industries in which the Company does business.  The discounted cash flow analysis establishes fair value by estimating the present value of the projected future cash flows of each reporting unit and applying a terminal growth rate.  The present value of estimated discounted future cash flows is determined using the Company’s estimates of revenue and costs for the reporting units, using a combination of historical results, industry data and competitor data, as well as appropriate discount rates.  The discount rate is determined using a weighted-average cost of capital that incorporates market participant data and a risk premium applicable to each reporting unit.  See Note 5 for an explanation of impairment charges recorded during 2012.  There were no impairment charges in 2013 or 2011.
Long-Lived Assets	'
	Long-Lived Assets
	The Company assesses the impairment of long-lived assets, other than goodwill and other indefinite-lived intangible assets, to determine if their carrying value may not be recoverable.  The determination of related estimated useful lives and whether or not these assets are impaired involves significant judgments, related primarily to the future profitability and/or future value of the assets.  Changes in the Company’s strategic plan and/or other-than-temporary changes in market conditions could significantly impact these judgments and could require adjustments to recorded asset balances.  Long-lived assets are evaluated for impairment at least annually, as well as whenever an event or change in circumstances has occurred that could have a significant adverse effect on the fair value of long-lived assets.  In the fourth quarter of 2012, in connection with the Company’s annual evaluation of long-lived assets, it determined that certain assets of its former Ophir Division (which are now a part of the Company’s Photonics Group) were impaired.  Accordingly, the Company recorded an impairment charge of $0.5 million related to fixed assets.  There were no impairment charges during 2013 or 2011.
Warranty	'
	Warranty
	Unless otherwise stated in the Company’s product literature or in its agreements with customers, products sold by the Company’s Photonics and Optics Groups generally carry a one-year warranty from the original invoice date on all product materials and workmanship, other than filters and gratings products, which generally carry a 90-day warranty, and laser beam profilers and dental CAD/CAM scanners, which generally carry a two-year warranty.  Products sold by the Photonics and Optics Groups to original equipment manufacturer (OEM) customers carry warranties generally ranging from 15 to 19 months.  Products sold by the Company’s Lasers Group carry warranties that vary by product and product component, but generally range from 90 days to two years.  In certain cases, such warranties for Lasers Group products are limited by either a set time period or a maximum amount of hourly usage of the product, whichever occurs first.  Defective products will be either repaired or replaced, generally at the Company’s option, upon meeting certain criteria.  The Company accrues a provision for the estimated costs that may be incurred for warranties relating to a product (based on historical experience) as a component of cost of sales.
Environmental Reserves	'
	Environmental Reserves
	The Company accrues for losses associated with environmental remediation obligations when such losses are probable and reasonably estimable.  Accruals for estimated losses from environmental remediation obligations generally are recognized no later than completion of the remedial feasibility study.  Such accruals are adjusted as further information develops or circumstances change.  Costs of future expenditures are discounted to their present value.  Recoveries of environmental remediation costs from other parties are recognized as assets when their receipt is deemed probable.  See Note 10 for additional information.
Revenue Recognition	'
	Revenue Recognition
	The Company recognizes revenue after title to and risk of loss of products have passed to the customer, or delivery of the service has been completed, provided that persuasive evidence of an arrangement exists, the price is fixed or determinable and collectability is reasonably assured.  Title to and risk of loss of products generally pass to the customer upon delivery, but in certain cases pass upon acceptance.  The Company recognizes revenue and related costs for arrangements with multiple deliverables, such as equipment and installation, as each element is delivered or completed based upon its relative selling price, determined based upon the price that would be charged on a standalone basis.  If a portion of the total contract price is not payable until installation is complete, the Company does not recognize such portion as revenue until completion of installation.  Revenue for extended service contracts is recognized over the related contract periods.  Revenue for programs involving design and development services and delivery of product prototypes and/or other deliverables is recognized upon the completion of specified milestones, or over the term of the program based upon the percentage of completion of the program, depending on the terms of the associated contract.  Certain sales to international customers are made through third-party distributors and revenue is recognized upon the sale to the distributor.  A discount below list price is generally provided at the time the product is sold to the distributor, and such discount is reflected as a reduction in net sales.  Freight costs billed to customers are included in net sales, and freight costs incurred are included in selling, general and administrative expenses.  Sales taxes collected from customers are recorded on a net basis and any amounts not yet remitted to tax authorities are included in accrued expenses and other current liabilities.
	Customers (including distributors) generally have 30 days from the original invoice date (generally 60 days for international customers) to return a standard catalog product purchase for exchange or credit.  Catalog products must be returned in the original condition and meet certain other criteria.  Custom, option-configured and certain other products as defined in the terms and conditions of sale cannot be returned without the Company’s consent.  For certain products, the Company establishes a sales return reserve based on the historical product returns.
Advertising	'
	Advertising
	The Company expenses the costs of advertising as incurred, except for the costs of its product catalogs, which are accounted for as prepaid supplies until they are distributed to customers or are no longer expected to be used.  Capitalized catalog costs were not material at December 28, 2013 and December 29, 2012.  Advertising costs, including the costs of the Company’s participation at industry trade shows, totaled $4.2 million, $3.9 million and $4.2 million for 2013, 2012 and 2011, respectively.
Shipping and Handling Costs	'
	Shipping and Handling Costs
	The Company expenses the costs of shipping and handling as incurred.  Shipping and handling costs of $4.7 million, $5.2 million and $5.0 million are included in selling, general and administrative expenses for 2013, 2012 and 2011, respectively.
Research and Development	'
	Research and Development
	All research and development costs are expensed as incurred.
Non-Controlling Interests	'
	Non-Controlling Interests
	In October 2011, the Company acquired Ophir Optronics Ltd. (Ophir), as discussed in Note 2.  As of December 28, 2013, Ophir’s subsidiaries, Ophir Japan, Ltd. in Japan, Ophir Optronics GmbH in Germany, and Optical Metrology Ltd. in Israel, had non-controlling interest holders of 33.3%, 25% and 14.1%, respectively.  Earnings (losses) attributable to the non-controlling interests are separately identified in the Company’s consolidated financial statements.
	During the first quarter of 2014, Ophir purchased all shares owned by the holders of the non-controlling interests in Optical Metrology Ltd for $0.9 million.
Income Taxes	'
	Income Taxes
	The Company utilizes the asset and liability method of accounting for income taxes.  Deferred income taxes are recognized for the future tax consequences of temporary differences using enacted statutory tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  Temporary differences include the difference between the financial statement carrying amounts, and the tax bases of existing assets and liabilities as well as operating loss and tax credit carryforwards.  In accordance with the provisions of ASC 740, a valuation allowance for deferred tax assets is recorded to the extent the Company cannot determine that the ultimate realization of the net deferred tax assets is more likely than not.
	The Company utilizes ASC 740-10-25, Income Taxes - Recognition, for the recognition, measurement and disclosure of uncertain tax positions.  Under ASC 740-10-25, income tax positions must meet the more-likely-than-not threshold to be recognized in the financial statements.  The Company’s policy is to record interest and penalties associated with unrecognized tax benefits as income tax expense.
Income (loss) per Share	'
	Income (loss) per Share
	Basic income (loss) per share is computed by dividing net income (loss) by the weighted-average number of shares of common stock outstanding during the period.  Diluted income per share is computed using the weighted-average number of shares of common stock outstanding during the period plus the dilutive effects of common stock equivalents (restricted stock units, stock options and stock appreciation rights) outstanding during the period, determined using the treasury stock method.  Diluted loss per share excludes the antidilutive effects of common stock equivalents outstanding during the periods.
Stock-Based Compensation	'
	Stock-Based Compensation
	The Company accounts for stock-based compensation in accordance with ASC 718, Compensation — Stock Compensation.  Under the fair value recognition provision of ASC 718, stock-based compensation cost is estimated at the grant date based on the fair value of the award.  The Company estimates the fair value of stock options and stock appreciation rights granted using the Black-Scholes-Merton option pricing model and a single option award approach.  The fair value of restricted stock unit awards is based on the closing market price of the Company’s common stock on the date of grant.
	Determining the appropriate fair value of stock options and stock appreciation rights at the grant date requires significant judgment, including estimating the volatility of the Company’s common stock and expected term of the awards.  The Company computes expected volatility based on historical volatility over the expected term.  The expected term represents the period of time that stock options and stock appreciation rights are expected to be outstanding and is determined based on historical experience, giving consideration to the contractual terms of the stock-based awards, vesting schedules and expected exercise behavior.
	A substantial portion of the Company’s restricted stock unit awards vest based upon the achievement of one or more financial performance thresholds established by the Compensation Committee of the Company’s Board of Directors.  Currently, such performance thresholds relate to the fiscal year in which the award is granted, and if and to the extent that such performance thresholds are met, the awards vest in equal one-third (1/3) annual installments.  Until the Company has determined that performance thresholds have been met, the amount of expense that the Company records relating to performance-based awards is estimated based on the likelihood of achieving the performance thresholds.  The amount of expense recorded by the Company is also based on estimated forfeitures.  The fair value of stock-based awards, adjusted for estimated forfeitures (and adjusted for estimated or actual achievement of performance thresholds in the case of awards having performance-based vesting conditions), is amortized using the straight-line attribution method over the requisite service period of the award, which is generally the vesting period.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes.  Actual results could differ from those estimates.  Significant estimates made in preparing the consolidated financial statements include (but are not limited to) those related to revenue recognition, the allowance for doubtful accounts, inventory reserves, warranty obligations, pension plans, asset impairment valuations, income tax valuations, and stock-based compensation expenses.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In February 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2013-02, Comprehensive Income: Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which requires companies to disclose significant amounts that have been reclassified out of accumulated other comprehensive income.  Amounts that are required to be reclassified in their entirety to net income must be disclosed either on the face of the income statement or in the notes to the financial statements.  Amounts that are not required to be reclassified in their entirety to net income in the same reporting period must be disclosed by a cross reference to other disclosures that provide additional information regarding such amounts.  ASU No. 2013-02 is effective for fiscal years and interim periods beginning after December 15, 2012.  The adoption of ASU No. 2013-02 has not had a material impact on the Company’s financial position or results of operations.
	In March 2013, the FASB issued ASU No. 2013-05, Foreign Currency Matters: Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity, which clarifies the guidance in Topics 810 and 830.  Topic 810 requires companies to deconsolidate a subsidiary or derecognize a group of assets if the parent ceases to hold a controlling financial interest in that subsidiary or group of assets.  Upon the loss of a controlling financial interest, the parent would recognize the cumulative translation adjustment in net income.  The guidance in Topic 810 does not distinguish between a sale or transfer of an investment in a foreign entity and a sale or transfer of a subsidiary or group of assets within a foreign entity.  Topic 830 requires the release of the cumulative translation adjustment into net income if a sale or transfer represented a complete or substantially complete liquidation of an investment in a foreign entity.  ASU No. 2013-05 clarifies that companies that cease to have a controlling financial interest in a subsidiary or group of assets within a foreign subsidiary should release the cumulative translation adjustment into net income if the sale or transfer results in a complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided.  ASU No. 2013-05 has become effective for fiscal years beginning after December 15, 2013.  The adoption of ASU No. 2013-05 has not had a material impact on the Company’s financial position or results of operations.
	In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which provides explicit guidance on the financial statement presentation of an unrecognized tax benefit.  ASU No. 2013-11 requires unrecognized tax benefits to be presented as a reduction to a deferred tax asset, except that, if a net operating loss carryforward, a similar tax loss or a tax credit carryforward is not available at the reporting date to settle any additional income taxes that would result from the disallowance of a tax position, then the unrecognized tax benefit should be presented as a liability.  ASU No. 2013-11 has become effective for fiscal years and interim periods beginning after December 15, 2013.  The adoption of ASU No. 2013-11 has not had a material impact on the Company’s financial position or results of operations.
