The Company’s customers include large multi-national original equipment manufacturers (“OEMs”) and their affiliated subsidiaries. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information (Accounting Standards Codification (“ASC”) 270, Interim Reporting ) and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all of the information necessary for a full presentation of financial position, results of operations, and cash flows in conformity with accounting principles generally accepted in the United States of America (“GAAP”). In the opinion of management, the condensed consolidated financial statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the results of the Company for the periods presented. Intercompany transactions and balances have been fully eliminated in consolidation. Operating results for interim periods are not necessarily indicative of results that may be expected for the fiscal year as a whole. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, certain components of equity, sales, expenses, and related disclosures at the date of the financial statements and during the reporting period. Actual results could differ materially from these estimates. For further information, refer to the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 29, 2017 .

The TLA Facility and TLB Facility are collectively referred to as the “Term Loan Facilities.” The TLB facility was issued at a 1% discount. Revolving Credit Facility The Revolving Credit Facility matures on October 27, 2020 . The Revolving Credit Facility also includes a $15 million sublimit for swingline loans and a $25 million sublimit for standby letters of credit. The Company is required to pay a commitment fee on the unused portion of the Revolving Credit Facility, which will range between 0.175% and 0.25% , depending on the Company’s Total Net Leverage Ratio (as defined in the Senior Secured Credit Facilities agreement). Interest rates on the Revolving Credit Facility, as well as the TLA Facility, are at the Company’s option, either at: (i) the prime rate plus the applicable margin, which will range between 0.75% and 2.25% , based on the Company’s Total Net Leverage Ratio, or (ii) the applicable LIBOR rate plus the applicable margin, which will range between 1.75% and 3.25% , based on the Company’s Total Net Leverage Ratio. As of March 30, 2018 , the Company had $74 million of outstanding borrowings on the Revolving Credit Facility and an available borrowing capacity of $116.8 million after giving effect to $9.2 million of outstanding standby letters of credit. As of March 30, 2018 , the weighted average interest rate on all outstanding borrowings under the Revolving Credit Facility was 5.10% . Subject to certain conditions, commitments under the Revolving Credit Facility may be increased through an incremental revolving facility so long as, on a pro forma basis, the Company’s first lien net leverage ratio does not exceed 4.25 :1.00. The outstanding amount of the Revolving Credit Facility approximated its fair value as of March 30, 2018 based upon the debt being variable rate and short-term in nature. Term Loan Facilities The TLA Facility and TLB Facility mature on October 27, 2021 and October 27, 2022 , respectively. Interest rates on the TLB Facility are, at the Company’s option, either at: (i) the prime rate plus 2.25% or (ii) the applicable LIBOR rate plus 3.25% , with LIBOR subject to a 1.00% floor. As of March 30, 2018 , the interest rates on the TLA Facility and TLB Facility were 5.13% and 4.99% , respectively. Additionally, if the Company receives both (a) a public corporate family credit rating from Moody’s Investors Services, Inc. of “B2” (stable outlook) or higher and (b) a public corporate credit rating from Standard & Poor’s Financial Services LLC of “B” (stable outlook) or higher, the interest rate margins for the TLB Facility will step down by an additional 25 basis points. Subject to certain conditions, one or more incremental term loan facilities may be added to the Term Loan Facilities so long as, on a pro forma basis, the Company’s first lien net leverage ratio does not exceed 4.25 :1.00. As of March 30, 2018 , the estimated fair value of the TLB Facility was approximately $839 million , based on quoted market prices for the debt, recent sales prices for the debt and consideration of comparable debt instruments with similar interest rates and trading frequency, among other factors, and is classified as Level 2 measurements within the fair value hierarchy. The par amount of the TLA Facility approximated its fair value as of March 30, 2018 based upon the debt being variable rate in nature. (4.) DEBT (Continued) Covenants The Revolving Credit Facility and TLA Facility contain covenants requiring (A) a maximum Total Net Leverage Ratio of 6.0 :1.00, subject to periodic step downs beginning in the third quarter of 2018 and (B) a minimum interest coverage ratio of adjusted EBITDA (as defined in the Senior Secured Credit Facilities) to interest expense of not less than 2.75 :1.00 subject to a step up beginning in the first quarter of 2019. As of March 30, 2018 , the Company was in compliance with these financial covenants. The TLB Facility does not contain any financial maintenance covenants. The Senior Secured Credit Facilities also contain negative covenants that restrict the Company’s ability to (i) incur additional indebtedness; (ii) create certain liens; (iii) consolidate or merge; (iv) sell assets, including capital stock of the Company’s subsidiaries; (v) engage in transactions with the Company’s affiliates; (vi) create restrictions on the payment of dividends or other amounts from the Company’s restricted subsidiaries; (vii) pay dividends on capital stock or redeem, repurchase or retire capital stock; (viii) pay, prepay, repurchase or retire certain subordinated indebtedness; (ix) make investments, loans, advances and acquisitions; (x) make certain amendments or modifications to the organizational documents of the Company or its subsidiaries or the documentation governing other senior indebtedness of the Company; and (xi) change the Company’s type of business.

As of March 30, 2018 , the Company was in compliance with all negative covenants under the Senior Secured Credit Facilities. The Senior Secured Credit Facilities provide for customary events of default. Upon the occurrence and during the continuance of an event of default, the outstanding advances and all other obligations under the Senior Secured Credit Facilities become immediately due and payable. 9.125% Senior Notes due 2023 On October 27, 2015, the Company completed a private offering of $360 million aggregate principal amount of 9.125% senior notes due on November 1, 2023 (the “Senior Notes”). All of the Senior Notes are outstanding as of March 30, 2018 .

The indenture for the Senior Notes contain certain restrictive covenants and provides for customary events of default, subject in certain cases to customary cure periods, as a result of which the Senior Notes and any unpaid interest would become due and payable. As of March 30, 2018 , the Company was in compliance with all restrictive covenants under the indenture governing the Senior Notes.

The loss from extinguishment of debt represents the portion of the unamortized discount and debt issuance costs related to the portion of the TLB Facility that was prepaid. Interest Rate Swap During 2016, the Company entered into a three -year $200 million interest rate swap to hedge against potential changes in cash flows on the outstanding variable rate debt, which is indexed to the one-month LIBOR rate. The variable rate received on the interest rate swap and the variable rate paid on the outstanding debt will have the same rate of interest, excluding the credit spread, and will reset and pay interest on the same date. The swap is being accounted for as a cash flow hedge. Information regarding the Company’s outstanding interest rate swap designated as a cash flow hedge as of March 30, 2018 is as follows (dollars in thousands): Notional Amount Start Date End Date Pay Fixed Rate Receive Current Floating Rate Fair Value Balance Sheet Location $ 200,000 Jun-17 Jun-20 1.1325 % 1.8750 % $ 5,544 Other Long-Term Assets The estimated fair value of the interest rate swap agreement represents the amount the Company would receive (pay) to terminate the contract.

The amounts recorded to Interest Expense during the quarters ended March 30, 2018 and March 31, 2017 related to the Company’s interest rate swap were a reduction of $0.2 million and $0.1 million , respectively. The estimated Accumulated Other Comprehensive Income related to the Company’s interest rate swaps that is expected to be reclassified into earnings within the next twelve months is a $2.0 million gain.

STOCK-BASED COMPENSATION (Continued) During the three months ended March 30, 2018 , the Company awarded grants of 0.3 million RSUs to certain members of management, of which 0.2 million are performance-based RSUs (“PSUs”) and the remainder are time-based RSUs that vest over three years. Of the PSUs, 0.1 million of the shares subject to each grant will be earned based upon achievement of specific Company performance metrics over a three -year performance period ending January 1, 2021, and 0.1 million of the shares subject to each grant will be earned based on the Company’s achievement of a relative total shareholder return (“TSR”) performance requirement, on a percentile basis, compared to a defined group of peer companies over a three -year performance period ending January 1, 2021. The number of PSUs earned based on the achievement of the Company performance metrics and TSR performance requirements, if any, will vest based on the recipient’s continuous service to the Company over a period of generally one to three years from the grant date. The time-based RSUs generally vest ratably over a three -year period. The grant-date fair value of the TSR portion of the PSUs granted during the three months ended March 30, 2018 was determined using the Monte Carlo simulation model on the date of grant, assuming the following (i) expected term of 2.92 years , (ii) risk free interest rate of 2.28% , (iii) expected dividend yield of 0.0% and (iv) expected stock price volatility over the expected term of the TSR award of 40% . The grant-date fair value of all other restricted stock awards is equal to the closing market price of Integer common stock on the date of grant.

OTHER OPERATING EXPENSES (Continued) Strategic Reorganization and Alignment During the fourth quarter of 2017, the Company began to take steps to better align its resources in order to enhance the profitability of its portfolio of products. This includes improving its business processes and redirecting investments away from projects where the market does not justify the investment, as well as aligning resources with market conditions and the Company’s future strategic direction. The Company estimates that it will incur aggregate pre-tax charges in connection with the strategic reorganization and alignment plan of between approximately $10 million to $12 million , of which an estimated $8 million to $12 million are expected to result in cash outlays. During the three months ended March 30, 2018 , the Company incurred charges relating to this initiative which primarily included severance and personnel related costs for terminated employees and fees for professional services. These expenses were primarily recorded within the Medical Segment. As of March 30, 2018 , total expense incurred for this initiative since inception was $9.4 million . These actions are expected to be substantially completed by the end of the second quarter of 2018. Manufacturing Alignment to Support Growth In 2017, the Company initiated several initiatives designed to reduce costs, improve operating efficiencies and increase manufacturing capacity to accommodate growth. The plan involves the relocation of certain manufacturing operations and expansion of certain of the Company's facilities. The Company estimates that it will incur aggregate pre-tax restructuring related charges in connection with the realignment plan of between approximately $9 million to $11 million , the majority of which are expected to be cash expenditures, and capital expenditures of between approximately $4 million to $6 million . Costs related to the Company’s manufacturing alignment to support growth initiative were primarily recorded within the Medical Segment. As of March 30, 2018 , total expense incurred for this initiative since inception was $0.9 million . These actions are expected to be substantially completed by the end of 2019. Consolidation and Optimization Initiatives In 2014, the Company initiated plans to transfer certain manufacturing functions performed at its facility in Beaverton, OR to a new facility in Tijuana, Mexico. Additionally, during 2016, the Company announced it would be closing its facility in Clarence, NY after transferring the machined component product lines manufactured in that facility to other Integer locations in the U.S. Costs related to the Company’s consolidation and optimization initiatives were primarily recorded within the Medical Segment. The Company does not expect to incur any material additional costs associated with these activities as they were substantially completed as of March 30, 2018. The following table summarizes the change in accrued liabilities related to the initiatives described above (in thousands): Severance and Retention Other Total December 29, 2017 $ 1,308 $ — $ 1,308 Restructuring charges 3,274 1,336 4,610 Cash payments (3,136 ) (897 ) (4,033 ) March 30, 2018 $ 1,446 $ 439 $ 1,885 Acquisition and Integration Expenses The Company did not incur any additional costs associated with these activities during the three months ended March 30, 2018 . During the three months ended March 31, 2017 , the Company incurred $4.8 million in acquisition and integration costs related to the acquisition of Lake Region Medical, consisting primarily of integration costs. Integration costs primarily include professional, consulting, severance, retention, relocation, and travel costs. The $0.4 million of acquisition and integration costs accrued as of December 29, 2017 were paid during the three months ended March 30, 2018 . These projects were completed as of December 29, 2017. Asset Dispositions, Severance and Other During the first quarter of 2018 and 2017, the Company recorded losses in connection with various asset disposals and/or write-downs. The 2017 amount also includes approximately $4.7 million in expense related to the Company’s leadership transitions, which were recorded within the corporate unallocated segment.

Income Taxes

Income Taxes	3 Months Ended

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The income tax provision for interim periods is determined using an estimate of the annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter, the estimate of the annual effective tax rate is updated, and if the estimated effective tax rate changes, a cumulative adjustment is made. There is a potential for volatility of the effective tax rate due to several factors, including discrete items, changes in the mix and amount of pre-tax income and the jurisdictions to which it relates, changes in tax laws and foreign tax holidays, business reorganizations, settlements with taxing authorities and foreign currency fluctuations. On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Tax Reform Act”) was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017, the transition of U.S international taxation from a worldwide tax system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017. Under GAAP, the effect of a change in tax laws or rates to be recognized in income from continuing operations for the period that includes the enactment date. As such, the Company recognized an estimate of the impact of the Tax Reform Act in the year ended December 29, 2017. The Company had an estimated $147.5 million of undistributed foreign earnings and profit subject to the deemed mandatory repatriation as of December 29, 2017 and recognized a provisional $14.7 million in 2017 for the one-time transition tax. The Company has sufficient U.S. net operating losses to offset cash tax liabilities associated with the repatriation tax. In addition, as a result of the reduction in the U.S. corporate income tax rate from 35% to 21% under the Tax Reform Act, the Company revalued its ending net deferred tax liabilities at December 29, 2017 and recognized a $56.5 million tax benefit in the Company’s Consolidated Statement of Operations and Comprehensive Income (Loss) for the year ended December 29, 2017. For further discussion of the impact of the Tax Reform Act for the year ended December 29, 2017 reference is made to Note 12 of the Company’s consolidated financial statements as of and for the year ended December 29, 2017 included in the Company’s 2017 Annual Report on Form 10-K for the year ended December 29, 2017 . On December 22, 2017, the Securities and Exchange Commission issued Staff Accounting Bulletin (“SAB”) No. 118 to address the application of GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Reform Act. The Company recognized the tax impact of the revaluation of deferred tax assets and liabilities and the provisional tax impact related to deemed repatriated earnings and included these amounts in its consolidated financial statements for the year ended December 29, 2017. The ultimate impact may differ from the provisional amount, possibly materially, due to, among other things, additional analysis, changes in interpretations and assumptions the Company has made, additional regulatory guidance that may be issued, and actions the Company may take as a result of the Tax Reform Act. This accounting is expected to be complete by the date that the Company’s 2017 U.S. corporate income tax return is filed in 2018. During the three month period ended March 30, 2018, there were no changes made to the provisional amount recorded in 2017. In addition to the reduction of the U.S. federal corporate tax rate and the one-time transition tax discussed above, the Tax Reform Act also established new tax laws that affect 2018, including, but not limited to: (i) a general elimination of U.S. federal income taxes on dividends from foreign subsidiaries; (ii) a new U.S. Income inclusion on certain earnings of foreign subsidiaries (Global Intangible Low-Taxed Income (“GILTI”)); (iii) the repeal of the domestic production activity deductions; (iv) limitations on the deductibility of certain executive compensation; (v) an elimination of the deduction for certain deemed “base erosion payments” made to foreign affiliates (Base Erosion and Anti-Abuse Tax (“BEAT”)); and (vi) a new provision that allows a domestic corporation an immediate deduction for a portion of its foreign derived intangible income (“FDII”). (8.) INCOME TAXES (Continued) The GILTI provisions require the Company to include foreign subsidiary earnings in excess of a deemed return on the foreign subsidiary’s tangible assets in its U.S. income tax return. The Company expects that it will be subject to incremental U.S. tax on GILTI income beginning in 2018. Because of the complexity of the new GILTI tax rules and the ongoing regulatory interpretation of the GILTI provisions, the Company is continuing its evaluation of this provision of the Tax Reform Act and the application of ASC 740, Income Taxes . Under GAAP, the Company is allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current period expense when incurred (the “period cost method”) or (2) factoring such amounts into the Company's measurement of its deferred taxes (the “deferred method”). The Company's selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on analyzing its global income to determine whether it expects to have future U.S. inclusions in taxable income related to GILTI and, if so, what the impact is expected to be. Whether the Company expects to have future U.S. inclusions in taxable income related to GILTI depends on not only the Company's current structure and estimated future results of global operations, but also its intent and ability to modify its structure. While the Company has included an estimate of GILTI in its estimated effective tax rate for 2018, it has not finalized its analysis and is not yet able to determine which method to elect. Adjustments related to the amount of GILTI Tax recorded in its condensed consolidated financial statements may be required based on the outcome of this election. The BEAT provisions in the Tax Reform Act eliminate the deduction of certain base-erosion payments made to related foreign corporations, and impose a minimum tax if greater than regular tax. The Company does not expect to be materially impacted by the BEAT or FDII provisions and has not included any impact of the provisions in its estimated effective tax rate for 2018, however, it is still in the process of analyzing the effect of these provisions of the Tax Reform Act. The Company’s worldwide effective tax rate for the first quarter of 2018 was 33.5% on $12.2 million of income before the provision for income taxes compared to (3.4)% on $4.2 million of losses before the provision for income taxes for the same period in 2017. The 2018 estimated annual effective tax rate includes the estimated impact of all Tax Reform Act provisions. The Company’s effective tax rate for 2018 differs from the U.S. federal statutory tax rate of 21% due principally to the estimated impact of the GILTI tax. The Company’s earnings outside the United States are generally taxed at blended rates that are marginally lower than the U.S. federal rate. The GILTI provisions require the Company to include foreign subsidiary earnings in excess of a deemed return on the foreign subsidiary’s tangible assets in its U.S. income tax return. There is a statutory deduction of 50% of the GILTI inclusion, however the deduction is subject to limitations based on U.S. taxable income. The Company currently has net operating losses to offset forecasted U.S. taxable income and as such, is temporarily subject to the deduction limitation which correspondingly imposes an incremental impact on U.S. income tax. The foreign jurisdictions in which the Company operates and where its foreign earnings are primarily derived, include Switzerland, Mexico, Germany, Uruguay, Malaysia and Ireland. The Company’s effective tax rate for 2017 differs from the U.S. federal statutory tax rate of 35% due principally to the Company’s earnings outside the U.S. which are generally taxed at rates lower than the U.S. federal rate. In addition, the Company had positive income before taxes in its foreign jurisdictions but losses before taxes in U.S. jurisdictions. As of March 30, 2018 , the balance of unrecognized tax benefits is approximately $12.7 million . It is reasonably possible that a reduction of up to $1.1 million of the balance of unrecognized tax benefits may occur within the next twelve months as a result of potential audit settlements. Approximately $12.3 million of the balance of unrecognized tax benefits would favorably impact the effective tax rate, net of federal benefit on state issues, if recognized.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Litigation The Company is subject to litigation arising from time to time in the ordinary course of its business. The Company does not expect that the ultimate resolution of any pending legal actions will have a material effect on its consolidated results of operations, financial position, or cash flows. However, litigation is subject to inherent uncertainties. As such, there can be no assurance that any pending legal action, which the Company currently believes to be immaterial, will not become material in the future. (9.) COMMITMENTS AND CONTINGENCIES In April 2013, the Company commenced an action against AVX Corporation and AVX Filters Corporation (collectively “AVX”) alleging that AVX had infringed on the Company’s patents by manufacturing and selling filtered feedthrough assemblies used in implantable pacemakers and cardioverter defibrillators that incorporate the Company’s patented technology. On January 26, 2016, a jury in the U.S. District Court for the District of Delaware returned a verdict finding that AVX infringed two Integer patents and awarded Integer $37.5 million in damages. Following a second trial in August 2017, a jury found that AVX infringed an additional Integer patent. On March 30, 2018, the U.S. District Court for the District of Delaware vacated the original damage award and ordered a retrial on damages, which is scheduled for January 2019. The Company has recorded no gains in connection with this litigation as no cash has been received. Product Warranties The Company generally warrants that its products will meet customer specifications and will be free from defects in materials and workmanship. The Company does not expect future product warranty claims will have a material effect on its condensed consolidated results of operations, financial position, or cash flows. However, there can be no assurance that any future customer complaints or negative regulatory actions regarding the Company’s products, which the Company currently believes to be immaterial, does not become material in the future. The change in product warranty liability was comprised of the following (in thousands): December 29, 2017 $ 4,745 Additions to warranty reserve 256 Warranty claims settled (69 ) March 30, 2018 $ 4,932 Foreign Currency Contracts The Company periodically enters into foreign currency forward contracts to hedge its exposure to foreign currency exchange rate fluctuations in its international operations. The Company has designated these foreign currency forward contracts as cash flow hedges. Accordingly, the effective portions of the unrealized gains and losses on these contracts are reported in Accumulated Other Comprehensive Income in the Condensed Consolidated Balance Sheets and are reclassified to earnings in the same periods during which the hedged transactions affect earnings. The estimated Accumulated Other Comprehensive Income related to the Company’s foreign currency contracts that is expected to be reclassified into earnings within the next twelve months is a $2.2 million loss. The impact to the Company’s results of operations from its forward contract hedges is as follows (in thousands): Three Months Ended March 30, March 31, Increase in sales $ 139 $ 24 Increase (decrease) in cost of sales (436 ) 1,062 Ineffective portion of change in fair value — — Information regarding outstanding foreign currency contracts designated as cash flow hedges as of March 30, 2018 is as follows (dollars in thousands): Aggregate Notional Amount Start Date End Date $/Foreign Currency Fair Value Balance Sheet Location $ 2,313 Jan 2018 Jun 2018 0.0514 Peso $ 142 Prepaid expenses and other current assets 22,798 Jan 2018 Dec 2018 0.0507 Peso 1,403 Prepaid expenses and other current assets 21,900 Jan 2018 Dec 2018 1.2089 Euro 644 Prepaid expenses and other current assets

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Assets and Liabilities Measured at Fair Value on a Recurring Basis Fair value measurement standards apply to certain financial assets and liabilities that are measured at fair value on a recurring basis (each reporting period). For the Company, these financial assets and liabilities include its derivative instruments. The Company does not have any nonfinancial assets or liabilities that are measured at fair value on a recurring basis. The Company also holds cost method and equity method investments which are measured at fair value on a nonrecurring basis. Foreign Currency Contracts The fair value of foreign currency contracts were determined through the use of cash flow models that utilize observable market data inputs to estimate fair value. These observable market data inputs included foreign exchange rate and credit spread curves. In addition, the Company received fair value estimates from the foreign currency contract counterparties to verify the reasonableness of the Company’s estimates. The Company’s foreign currency contracts are categorized in Level 2 of the fair value hierarchy. Refer to Note 9 “Commitments and Contingencies” for further discussion regarding the fair value of the Company’s foreign currency contracts. Interest Rate Swaps The fair value of the Company’s interest rate swap contracts outstanding were determined through the use of a cash flow model that utilizes observable market data inputs. These observable market data inputs include LIBOR, swap rates, and credit spread curves. In addition, the Company received a fair value estimate from the interest rate swap counterparty to verify the reasonableness of the Company’s estimate. Refer to Note 4 “Debt” for further discussion regarding the fair value of the Company’s interest rate swap. The following table provides information regarding assets and liabilities recorded at fair value on a recurring basis (in thousands): Fair Value Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) March 30, 2018 Assets: Foreign currency contracts (Note 9) $ 2,189 $ — $ 2,189 $ — Assets: Interest rate swap (Note 4) 5,544 — 5,544 — December 29, 2017 Assets: Interest rate swaps $ 4,279 $ — $ 4,279 $ — Liabilities: Foreign currency contracts 861 — 861 — Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Fair value standards also apply to certain assets and liabilities that are measured at fair value on a nonrecurring basis. The carrying amounts of cash, accounts receivable, accounts payable, and accrued expenses approximate fair value because of the short-term nature of these items. Refer to Note 4 “Debt” for further discussion regarding the fair value of the Company’s Senior Secured Credit Facilities and Senior Notes. A summary of the valuation methodologies for assets and liabilities measured on a nonrecurring basis is as follows: Cost and Equity Method Investments The Company holds investments in equity and other securities that are accounted for as either cost method or equity method investments, which are classified as Other Assets on the Condensed Consolidated Balance Sheets. The total carrying value of these investments is reviewed quarterly for changes in circumstance or the occurrence of events that suggest the Company’s investment may not be recoverable. The fair value of cost method investments are not adjusted if there are no identified events or changes in circumstances that may have a material effect on the fair value of the investments. The aggregate recorded amount of cost and equity method investments at March 30, 2018 and December 29, 2017 was $25.8 million and $20.8 million , respectively. (12.) FAIR VALUE MEASUREMENTS (Continued) As of March 30, 2018 and December 29, 2017 , the recorded amount of the Company’s equity method investment was $18.8 million and $13.8 million , respectively. The Company’s equity method investment is in a Chinese venture capital fund focused on investing in life sciences companies. This fund accounts for its investments at fair value with the unrealized change in fair value of these investments recorded as income or loss to the fund in the period of change. As of March 30, 2018 , the Company owned 6.6% of this fund. During the three months ended March 30, 2018 and March 31, 2017 , the Company recognized a net gain of $5.0 million and a net loss of $0.4 million , respectively, on its equity method investment. The Company’s recorded amount of cost method investments was $7.0 million at March 30, 2018 and December 29, 2017. The Company did not recognize any impairment charges related to cost method investments during the three months ended March 30, 2018 and March 31, 2017 . The fair value of these investments is primarily determined by reference to recent sales data of similar shares to independent parties in an inactive market and categorized in Level 2 of the fair value hierarchy.

Revenue from Contract with Customer [Abstract]
REVENUE FROM CONTRACTS WITH CUSTOMERS	REVENUE FROM CONTRACTS WITH CUSTOMERS The majority of the Company’s revenues consist of sales of various medical devices and products to large, multinational OEMs and their affiliated subsidiaries. The Company considers the customer’s purchase order, which in some cases is governed by a long-term agreement, and the Company’s corresponding sales order acknowledgment as the contract with the customer. The Company has elected to adopt the practical expedient provided in ASC 340-40-25-4 and recognize the incremental costs of obtaining a contract, which are primarily sales commissions, as expense when incurred because the amortization period is less than one year. Performance Obligations The Company considers each shipment of an individual product included on a purchase order to be a separate performance obligation, as each shipment is separately identifiable and the customer can benefit from each individual product separately from the other products included on the purchase order. Accordingly, a contract can have one or more performance obligations to manufacture products. Standard payment terms range from 30 to 90 days and can include a discount for early payment. The Company does not offer its customers a right of return. Rather, the Company warrants that each unit received by the customer will meet the agreed upon technical and quality specifications and requirements. Only when the delivered units do not meet these requirements can the customer return the non-compliant units as a corrective action under the warranty. The remedy offered to the customer is repair of the returned units or replacement if repair is not viable. Accordingly, the Company records a warranty reserve and any warranty activities are not considered to be a separate performance obligation. Historically, warranty reserves have not been material. Transaction Price Generally, the transaction price of the Company’s contracts consists of a unit price for each individual product included in the contract, which can be fixed or variable based on the number of units ordered. In some instances, the transaction price also includes a rebate for meeting certain volume-based targets over a specified period of time. The transaction price of a contract is determined based on the unit price and the number of units ordered, reduced by the rebate expected to be earned on those units. Rebates are estimated based on the expected achievement of the volume-based target using the most likely amount method and updated quarterly. Any adjustments to these estimates are recognized under the cumulative catch-up method, such that impact of the adjustment is recognized in the period in which it is identified. The transaction price is allocated to each performance obligation on a relative standalone selling price basis. As the majority of products sold to customers are manufactured to meet the specific requirements and technical specifications of that customer, the products are considered unique to that customer and the unit price stated in the contract is considered the standalone selling price. The Company has elected to adopt the practical expedient provided in ASC 606-10-50-14 and not disclose the aggregate amount of the transaction price allocated to unsatisfied performance obligations and an expectation of when those amounts are expected to be recognized as revenue because the majority of contracts have an original expected duration of one year or less. Revenue Recognition The Company recognizes revenue at the point in time when a performance obligation is satisfied and the customer has obtained control of the products. Control is defined as the ability to direct the use of and obtain substantially all of the remaining benefits of the product. The customer obtains control of the products when title and risk of ownership transfers to them, which is primarily based upon shipping terms. Accordingly, the majority of the Company’s revenues are recognized at the point of shipment. In instances where title and risk of ownership do not transfer to the customer until the products have reached the customer’s location, revenue is recognized at that point in time. Revenue is recognized net of sales tax, value-added taxes and other taxes. Contract Modifications Contract modifications, which can include a change in either or both scope and price, most often occur related to contracts that are governed by a long-term arrangement. Contract modifications typically relate to the same products already governed by the long-term arrangement, and therefore, are accounted for as part of the existing contract. If a contract modification is for additional products, it is accounted for as a separate contract. (14.) REVENUE FROM CONTRACTS WITH CUSTOMERS (Continued) Disaggregated Revenue In general, the Company's business segmentation is aligned according to the nature and economic characteristics of its products and customer relationships and provides meaningful disaggregation of each business segment's results of operations. For a summary by disaggregated product line sales for each segment, refer to Note 13, “Segment Information.” Additionally, the tables below disaggregate the Company’s revenues based upon significant customers, which are defined as any customer who individually represents 10% or more of a segment’s total revenues, and ship to country, which is defined as any country where 10% or more of a segment’s total revenues are shipped to. The Company believes that these categories best depict how the nature, amount, timing and uncertainty of revenues and cash flows are affected by economic factors. The following table presents revenues by customer for the three months ended March 30, 2018. Customer Medical Non-Medical Customer A 17 % — % Customer B 16 % — % Customer C 15 % — % Customer D — % 19 % Customer E — % 11 % All other customers 52 % 70 % The following table presents revenues by ship to country for the three months ended March 30, 2018. Ship to Location Medical Non-Medical United States 55 % 69 % Puerto Rico 10 % — % Canada — % 11 % All other Countries 35 % 20 % Contract Balances The timing of revenue recognition, billings and cash collections results in billed accounts receivable and less frequently, unearned revenue. Accounts receivable are recorded when the right to consideration becomes unconditional. Unearned revenue is recorded when customers pay or are billed in advance of the Company’s satisfaction of performance obligations. Contract liabilities were $4.4 million and $3.6 million as of March 30, 2018 and December 29, 2017, respectively, and are classified as Accrued Expenses on the Condensed Consolidated Balance Sheets. During the three months ended March 30, 2018, we recognized $0.7 million of revenue that was included in the contract liability balance as of December 29, 2017. The Company does no t have any contract assets.

Impact of Recently Issued Accou

Impact of Recently Issued Accounting Standards	3 Months Ended

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS	IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS The following table provides a brief description of recent Accounting Standard Updates ("ASU") issued by the Financial Accounting Standards Board ("FASB"): Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The new guidance allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act and will improve the usefulness of information reported to financial statement users. December 29, 2018 (beginning of 2019 fiscal year). Early adoption is permitted. The Company is currently evaluating the impact that the adoption of this ASU will have on its consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities. The new guidance improves the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. December 29, 2018. Early adoption is permitted. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial statements. In March 2017, the FASB issued ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The new guidance clarifies the presentation and classification of the components of net periodic benefit costs in the consolidated statement of operations. December 30, 2017. The Company adopted the new guidance effective December 30, 2017, the beginning of its 2018 fiscal year, using the retrospective transition method, as part of the FASB's simplification initiative. See Adoption of ASU 2017-07 section below for additional information. In October 2016, the FASB issued ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory. The new guidance requires the income tax consequences of an intra-entity transfer of assets other than inventory to be recognized when the transfer occurs rather than deferring until an outside sale has occurred. December 30, 2017. The Company adopted the new guidance effective December 30, 2017. The adoption of the new guidance did not have a material impact to the Company. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments. The new guidance clarifies the presentation and classification of certain cash receipts and cash payments in the statement of cash flows. December 30, 2017. The Company adopted the new guidance effective December 30, 2017. The adoption of the new guidance did not have a material impact to the Company. In February 2016, the FASB issued ASU 2016-02, Leases. The new guidance supersedes the lease guidance under ASC Topic 840, Leases , resulting in the creation of FASB ASC Topic 842, Leases . The guidance requires a lessee to recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term for both finance and operating leases. December 29, 2018. Early adoption is permitted. The Company is currently evaluating its population of leases, and is continuing to assess all potential impacts of the standard, but currently believes the most significant impact relates to its accounting for real estate operating leases. The Company anticipates recognition of additional assets and corresponding liabilities related to leases upon adoption, but has not yet quantified these at this time. The Company plans to adopt the standard effective December 29, 2018. (15.) IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS (Continued) Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. The new guidance updates certain aspects of recognition, measurement, presentation and disclosure of financial instruments. December 30, 2017. The Company adopted the new guidance effective December 30, 2017. The adoption of the new guidance did not have a material impact to the Company. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. Since that date, the FASB has issued additional ASUs clarifying certain aspects of ASU 2014-09. The new guidance requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. The new guidance provides alternative methods of adoption. Subsequent guidance issued after May 2014 did not change the core principle of ASU 2014-09. December 30, 2017. The Company adopted the new guidance effective December 30, 2017, using the modified retrospective transition method applied to those contracts which were not completed as of December 30, 2017. Prior period amounts have not been adjusted and continue to be reflected in accordance with the Company’s historical accounting. The adoption of this ASU did not have a material impact on the consolidated financial statements and therefore no cumulative adjustment was recorded to equity. The Company has updated its internal controls for changes and expanded disclosures have been made in the Notes to the Financial Statements as a result of adopting the standard. (See Note 14, “Revenue from Contracts with Customers”). Adoption of ASU 2017-07 On December 30, 2017, we retrospectively adopted the new accounting guidance on presentation of net periodic pension costs (ASU 2017-07). That guidance requires that we disaggregate the service cost component of net benefit costs and report those costs in the same line item or items in the Condensed Consolidated Statements of Operations and Comprehensive Income as other compensation costs arising from services rendered by the pertinent employees during the period. The other non-service components of net benefit costs are required to be presented separately from the service cost component. Following the adoption of this guidance, we continue to record the service cost component of net benefit costs in Cost of Sales and Selling, General and Administrative expenses. The interest cost component of net benefit costs is now recorded in Interest Expense and the remaining components of net benefit costs, amortization of net losses and expected return on plan assets, are now recorded in Other Loss, Net.

Basis of Presentation (Policies

Basis of Presentation (Policies)	3 Months Ended

Accounting Policies [Abstract]
Interim Basis of Accounting	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information (Accounting Standards Codification (“ASC”) 270, Interim Reporting ) and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all of the information necessary for a full presentation of financial position, results of operations, and cash flows in conformity with accounting principles generally accepted in the United States of America (“GAAP”). In the opinion of management, the condensed consolidated financial statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the results of the Company for the periods presented. Intercompany transactions and balances have been fully eliminated in consolidation. Operating results for interim periods are not necessarily indicative of results that may be expected for the fiscal year as a whole. For further information, refer to the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 29, 2017 .
Use of Estimates	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, certain components of equity, sales, expenses, and related disclosures at the date of the financial statements and during the reporting period. Actual results could differ materially from these estimates.
Fiscal Period	The Company utilizes a fifty-two, fifty-three week fiscal year ending on the Friday nearest December 31. The first quarter of 2018 and 2017 each contained 13 weeks and ended on March 30, and March 31, respectively.
Income Taxes	The income tax provision for interim periods is determined using an estimate of the annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter, the estimate of the annual effective tax rate is updated, and if the estimated effective tax rate changes, a cumulative adjustment is made. There is a potential for volatility of the effective tax rate due to several factors, including discrete items, changes in the mix and amount of pre-tax income and the jurisdictions to which it relates, changes in tax laws and foreign tax holidays, business reorganizations, settlements with taxing authorities and foreign currency fluctuations.
Cost And Equity Method Investments	The Company holds investments in equity and other securities that are accounted for as either cost method or equity method investments, which are classified as Other Assets on the Condensed Consolidated Balance Sheets.

Impact of Recently Issued Acc36

Impact of Recently Issued Accounting Standards (Tables)	3 Months Ended

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Summary of Recently Issued Accounting Standards	The following table provides a brief description of recent Accounting Standard Updates ("ASU") issued by the Financial Accounting Standards Board ("FASB"): Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The new guidance allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act and will improve the usefulness of information reported to financial statement users. December 29, 2018 (beginning of 2019 fiscal year). Early adoption is permitted. The Company is currently evaluating the impact that the adoption of this ASU will have on its consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities. The new guidance improves the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. December 29, 2018. Early adoption is permitted. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial statements. In March 2017, the FASB issued ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The new guidance clarifies the presentation and classification of the components of net periodic benefit costs in the consolidated statement of operations. December 30, 2017. The Company adopted the new guidance effective December 30, 2017, the beginning of its 2018 fiscal year, using the retrospective transition method, as part of the FASB's simplification initiative. See Adoption of ASU 2017-07 section below for additional information. In October 2016, the FASB issued ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory. The new guidance requires the income tax consequences of an intra-entity transfer of assets other than inventory to be recognized when the transfer occurs rather than deferring until an outside sale has occurred. December 30, 2017. The Company adopted the new guidance effective December 30, 2017. The adoption of the new guidance did not have a material impact to the Company. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments. The new guidance clarifies the presentation and classification of certain cash receipts and cash payments in the statement of cash flows. December 30, 2017. The Company adopted the new guidance effective December 30, 2017. The adoption of the new guidance did not have a material impact to the Company. In February 2016, the FASB issued ASU 2016-02, Leases. The new guidance supersedes the lease guidance under ASC Topic 840, Leases , resulting in the creation of FASB ASC Topic 842, Leases . The guidance requires a lessee to recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term for both finance and operating leases. December 29, 2018. Early adoption is permitted. The Company is currently evaluating its population of leases, and is continuing to assess all potential impacts of the standard, but currently believes the most significant impact relates to its accounting for real estate operating leases. The Company anticipates recognition of additional assets and corresponding liabilities related to leases upon adoption, but has not yet quantified these at this time. The Company plans to adopt the standard effective December 29, 2018. (15.) IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS (Continued) Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. The new guidance updates certain aspects of recognition, measurement, presentation and disclosure of financial instruments. December 30, 2017. The Company adopted the new guidance effective December 30, 2017. The adoption of the new guidance did not have a material impact to the Company. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. Since that date, the FASB has issued additional ASUs clarifying certain aspects of ASU 2014-09. The new guidance requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. The new guidance provides alternative methods of adoption. Subsequent guidance issued after May 2014 did not change the core principle of ASU 2014-09. December 30, 2017. The Company adopted the new guidance effective December 30, 2017, using the modified retrospective transition method applied to those contracts which were not completed as of December 30, 2017. Prior period amounts have not been adjusted and continue to be reflected in accordance with the Company’s historical accounting. The adoption of this ASU did not have a material impact on the consolidated financial statements and therefore no cumulative adjustment was recorded to equity. The Company has updated its internal controls for changes and expanded disclosures have been made in the Notes to the Financial Statements as a result of adopting the standard. (See Note 14, “Revenue from Contracts with Customers”).
