Accounting Policies [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION Integer Holdings Corporation (together with its consolidated subsidiaries, “Integer” or the “Company”) is a publicly traded corporation listed on the New York Stock Exchange under the symbol “ITGR.” Integer is one of the largest medical device outsource manufacturers in the world serving the cardiac, neuromodulation, vascular, orthopedics, advanced surgical and portable medical markets. The Company provides innovative, high-quality medical technologies that enhance the lives of patients worldwide. In addition, it develops batteries for high-end niche applications in the energy, military, and environmental markets. The Company’s reportable segments are: (1) Medical and (2) Non-Medical. The Company’s customers include large multi-national original equipment manufacturers (“OEMs”) and their affiliated subsidiaries. On May 3, 2018, the Company entered into a definitive agreement to sell the Advanced Surgical and Orthopedic product lines (the “AS&O Product Line”) within its Medical segment to Viant (formerly MedPlast, LLC), and on July 2, 2018 completed the sale. The results of operations of the AS&O Product Line are reported as discontinued operations in the Condensed Consolidated Statements of Operations for all periods presented. The Condensed Consolidated Statements of Cash Flows includes cash flows related to the discontinued operations due to Integer’s centralized treasury and cash management processes, and, accordingly, cash flow amounts for discontinued operations are disclosed in Note 2 “Discontinued Operations and Divestiture.” All results and information in the condensed consolidated financial statements are presented as continuing operations and exclude the AS&O Product Line unless otherwise noted specifically as discontinued operations. Refer to Note 2 “Discontinued Operations and Divestiture” for additional information. 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 28, 2018 . The Company utilizes a fifty-two, fifty-three week fiscal year ending on the Friday nearest December 31. The second quarter of 2019 and 2018 each contained 13 weeks and ended on June 28 and June 29, respectively. The Company’s 2019 fiscal year will end on January 3, 2020 and will be a fifty-three week period. Fiscal year 2018 ended on December 28, 2018 and was a fifty-two week period. Recent Accounting Pronouncements The Company considers the applicability and impact of all Accounting Standard Updates (“ASU”) issued by the Financial Accounting Standards Board ("FASB"). ASUs not yet adopted that are not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated result of operations, financial position and cash flows. With the exception of the accounting pronouncements adopted as discussed below, there have been no new or material changes to the significant accounting policies discussed in the Company’s Annual Report on Form 10-K for the fiscal year ended December 28, 2018, that are of significance, or potential significance, to the Company. (1.) BASIS OF PRESENTATION (Continued) Recently Adopted Accounting Guidance Adoption of ASC Topic 842 Effective December 29, 2018, the Company adopted ASC 842, Leases, which requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous guidance. The Company elected to transition to ASC 842 using the option to not restate comparative periods and apply the standard as of the date of initial application. In addition, certain practical expedients were elected which permit the Company to not reassess whether existing contracts are or contain leases, to not reassess the lease classification of any existing leases, and to not reassess initial direct costs for any existing leases. The Company also elected the practical expedient to not separate lease and non-lease components for all classes of underlying assets and the practical expedient related to land easements, allowing the Company to carry-forward its accounting treatment for land easements on existing agreements. The Company did not elect the practical expedient pertaining to the use of hindsight. The Company also made an accounting policy election to keep leases with an initial term of 12 months or less and no purchase option the Company is reasonably certain to exercise off the balance sheet for all classes of underlying assets. As a result of the adoption of ASC 842, the Company recognized operating lease right-of-use assets of $40.9 million and lease liabilities of $43.4 million on December 29, 2018. The difference between the lease assets and lease liabilities primarily represents the existing prepaid rent assets, deferred rent liabilities, and tenant improvement allowances, along with a cumulative-effect adjustment to beginning retained earnings. The adoption of ASC 842 did not have a material impact on the Company’s Condensed Consolidated Statement of Operations and Condensed Consolidated Statement of Cash Flows for the periods presented. Refer to Note 11 “Leases” for additional information on the Company’s leases. Adoption of ASU 2017-12 and ASU 2018-16 In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities . ASU 2017-12 amends the designation and measurement guidance for qualifying hedging transactions and the presentation of hedge results in an entity’s financial statements. The new guidance removes the concept of separately measuring and reporting hedge ineffectiveness and requires a company to present the earnings effect of the hedging instrument, including any ineffectiveness, in the same income statement line item in which the earnings effect of the hedged item is reported. ASU 2017-12 continues to allow an entity to exclude the time value of options and forward points from the assessment of hedge effectiveness. For excluded components in cash flow hedges, the base recognition model under this ASU is an amortization approach. An entity still may elect to record changes in the fair value of the excluded component currently in earnings; however, such an election will need to be applied consistently to similar hedges. The Company has elected to continue to record changes in the fair value of the excluded components of its derivative instruments currently in earnings given their highly effective nature. Finally, this ASU continues to require an initial prospective quantitative hedge effectiveness assessment and documentation at hedge inception. However, if certain criteria are met, entities can elect to subsequently perform prospective and retrospective effectiveness assessments qualitatively, unless facts and circumstances change, and the hedge effectiveness assessment generally does not need to be completed until the first quarterly hedge effectiveness assessment date (i.e., up to three months). The Company adopted ASU 2017-12 on December 29, 2018, the first day of the Company’s 2019 fiscal year, which did not materially affect the Company’s results of operations. The Company adopted the guidance on the modified retrospective basis and did not recognize a cumulative effect adjustment upon adoption as the Company had not recognized ineffectiveness on any of the hedging instruments existing as of the date of adoption. Refer to Note 14 “Financial Instruments and Fair Value Measurements” for additional information and disclosures of the Company’s derivatives and hedging activities. In October 2018, the FASB issued ASU 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes . The amendments in ASU 2018-16 permit the use of the OIS rate based on SOFR as a benchmark interest rate for hedge accounting purposes under Topic 815. The amendments in this update were effective for fiscal years beginning after December 15, 2018. The Company adopted this guidance prospectively as of December 29, 2018, concurrent with the adoption of ASU 2017-12, to be applied on a prospective basis for qualifying new or redesignated hedging relationships entered into on or after the date of adoption. Adoption of this guidance had no impact on the Condensed Consolidated Financial Statements.

Discontinued Operations and Disposal Groups [Abstract]
DISCONTINUED OPERATIONS	DISCONTINUED OPERATIONS AND DIVESTITURE On May 3, 2018, the Company entered into a definitive agreement to sell its AS&O Product Line to Viant, and on July 2, 2018, completed the sale, collecting cash proceeds of approximately $581 million , which is net of transaction costs and adjustments set forth in the definitive agreement. In connection with the sale, the parties executed a transition services agreement whereby the Company would provide certain corporate services (including accounting, payroll, and information technology services) to Viant for a period of up to one year from the date of the closing to facilitate an orderly transfer of business operations. Viant paid Integer for these services as specified in the transition services agreement, which ended during the second quarter of 2019. For the performance of services during the three and six months ended June 28, 2019 , the Company recognized $1.2 million and $2.9 million , respectively, of income under the transition services agreement. For the six months ended June 28, 2019 , $0.1 million is recorded as a reduction of Cost of sales and for the three and six months ended June 28, 2019 , $1.2 million and $2.8 million , respectively, is recorded as a reduction of Selling, general and administrative expenses. In addition, the parties executed long-term supply agreements under which the Company and Viant have agreed to supply the other with certain products at prices specified in the agreements for a term of three years . In connection with the closing of the transaction but prior to a net working capital adjustment, the Company recognized a pre-tax gain on sale of discontinued operations of $195.0 million during the year ended December 28, 2018. During the quarter ended June 28, 2019, the Company received $4.8 million due to a net working capital adjustment agreed to with Viant. This was recognized as gain on sale from discontinued operations, during the quarter ended June 28, 2019. The operating results of the AS&O Product Line have been classified as discontinued operations in the Condensed Consolidated Statements of Operations for all periods presented.

STOCK-BASED COMPENSATION (Continued) During the six months ended June 28, 2019 , the Company awarded grants to members of its Board of Directors and certain members of management. The Board of Directors received grants of RSUs that vest in equal quarterly installments of 25% on the first day of each quarter of the Company’s 2019 fiscal year. The members of management received either RSUs or a mix of RSUs and PRSUs. The RSUs vest ratably, subject to the recipient’s continuous service to the Company over a period of generally three to four years from the grant date. For the Company's PRSUs, in addition to service conditions, the ultimate number of shares to be earned depends on the achievement of financial performance or market-based conditions. The financial performance condition is based on the Company's sales targets. The market conditions are 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 three year performance periods. The Company uses a Monte Carlo simulation model to determine the grant-date fair value of TSR awards. 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. The weighted average fair value and assumptions used to value the TSR portion of the PRSUs granted are as follows: Six Months Ended June 28, June 29, Weighted average fair value $ 117.03 $ 37.46 Risk-free interest rate 2.46 % 2.28 % Expected volatility 40 % 40 % Expected life (in years) 2.8 2.9 Expected dividend yield — % — % The following table summarizes RSA and RSU activity: Time-Vested Activity Weighted Average Fair Value Nonvested at December 28, 2018 142,236 $ 49.78 Granted 97,296 83.70 Vested (18,310 ) 59.66 Forfeited (5,310 ) 48.57 Nonvested at June 28, 2019 215,912 $ 64.29 The following table summarizes PRSU activity: Performance- Vested Activity Weighted Average Fair Value Nonvested at December 28, 2018 287,134 $ 36.15 Granted 50,492 101.17 Vested (75,008 ) 28.41 Forfeited (65,293 ) 32.68 Nonvested at June 28, 2019 197,325 $ 56.87

These initiatives include 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, including projects reported in discontinued operations, of between approximately $20 million to $ 22 million , of which an estimated $16 million to $20 million are expected to result in cash outlays. During the six months ended June 28, 2019 , the Company incurred charges relating to this initiative, which primarily included severance and fees for professional services recorded within the Medical segment. As of June 28, 2019 , total expense incurred for this initiative since inception, including amounts reported in discontinued operations, was $19.9 million . These actions are expected to be substantially completed by the end of 2019. Manufacturing Alignment to Support Growth In 2017, the Company initiated several initiatives designed to reduce costs, increase manufacturing capacity to accommodate growth and improve operating efficiencies. 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 $7 million to $9 million , the majority of which are expected to be cash expenditures. Costs related to the Company’s manufacturing alignment to support growth initiative were primarily recorded within the Medical segment. As of June 28, 2019 , total expense incurred for this initiative since inception, including amounts reported in discontinued operations, was $4.6 million . These actions are expected to be substantially completed by the end of 2019. Consolidation and Optimization Initiatives 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. The following table summarizes the change in accrued liabilities, presented within Accrued Expense and Other Current Liabilities on the Condensed Consolidated Balance Sheets, related to the initiatives described above (in thousands): Severance and Retention Other Total December 28, 2018 $ 1,668 $ 202 $ 1,870 Restructuring charges 1,263 3,273 4,536 Cash payments (887 ) (3,469 ) (4,356 ) June 28, 2019 $ 2,044 $ 6 $ 2,050 Asset Dispositions, Severance and Other During the six months ended June 28, 2019 and June 29, 2018, the Company recorded expenses related to other initiatives not described above, which relate primarily to integration and operational initiatives to reduce future operating costs and improve operational efficiencies.

Income Taxes

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. In addition, we continue to explore tax planning opportunities that may have a material impact on our effective tax rate. The Company’s effective tax rate for continuing operations for the second quarter of 2019 was 19.0% on $34.8 million of income from continuing operations before taxes compared to 27.5% on $31.8 million of income from continuing operations before taxes for the same period in 2018. The Company’s effective tax rate for continuing operations for the first six months of 2019 was 17.3% on $60.0 million of income from continuing operations before taxes compared to 28.1% on $50.3 million of income from continuing operations before taxes for the same period of 2018. The difference between the Company’s effective tax rates and the U.S. federal statutory income tax rate of 21% for the second quarter and first six months of 2019 is primarily attributable to discrete tax benefits of $0.4 million and $2.1 million , respectively, as well as the estimated net impact of the Global Intangible Low-Taxed Income tax, the Company’s earnings outside the U.S., which are generally taxed at rates that differ from the U.S federal rate, and the availability of certain tax credits. The discrete tax benefits for 2019 are predominately related to excess tax benefits recognized upon vesting of RSUs or exercise of stock options. As of June 28, 2019 , the balance of unrecognized tax benefits from continuing operations is approximately $5.4 million . It is reasonably possible that a reduction of up to $0.9 million of the balance of unrecognized tax benefits may occur within the next twelve months as a result of potential audit settlements. Approximately $5.3 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. 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. Two juries in the U.S. District Court for the District of Delaware have returned verdicts finding that AVX infringed on three of the Company’s patents and awarded the Company $37.5 million in damages. In March 2018, the U.S. District Court for the District of Delaware vacated the original damage award and ordered a retrial on damages. In the January 2019 retrial on damages, the jury awarded the Company $22.2 million in damages. That award is subject to post-trial proceedings. On July 31, 2019, the U. S. District Court for the District of Delaware entered an order in the AVX litigation denying AVX’s post-trial motion to overturn the jury verdict in favor of the Company. To date, the Company has recorded no gains in connection with this litigation. (10.) COMMITMENTS AND CONTINGENCIES (Continued) 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 product warranty liability is presented within Accrued Expense and Other Current Liabilities on the Condensed Consolidated Balance Sheets. The change in product warranty liability was comprised of the following (in thousands): December 28, 2018 $ 2,600 Additions to warranty reserve 195 Adjustments to pre-existing warranties (635 ) Warranty claims settled (465 ) June 28, 2019 $ 1,695

Leases

Leases [Abstract]
Leases	LEASES The Company primarily leases certain office and manufacturing facilities under operating leases, with additional operating leases for machinery, office equipment and vehicles. An arrangement is considered to contain a lease if it conveys the right to use an identified asset for a period of time in exchange for consideration. If it is determined that an arrangement contains a lease, classification of a lease as operating or finance is determined by evaluating the five criteria outlined within ASC 842 at inception. The Company does not currently have any finance leases. The Company’s lease agreements do not contain any residual value guarantees or any material restrictive covenants. Right-of-use (“ROU”) lease assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make payments in exchange for that right of use. Operating lease ROU assets are presented as Operating Lease Assets, the current portion of operating lease liabilities are presented within Accrued Expense and Other Current Liabilities, and the non-current portion of operating lease liabilities are presented as Operating Lease Liabilities on the Condensed Consolidated Balance Sheets. The current portion of operating lease liabilities was $7.3 million as of June 28, 2019 . Leases with a term of 12 months or less are not recorded on the balance sheet. The Company’s real estate leases often contain options to renew, and less frequently, termination options. The exercise of such renewal and termination options are generally at the Company’s sole discretion. The Company evaluates renewal and termination options at lease commencement to determine if such options are reasonably certain to be exercised based on economic factors. For certain leases where rent escalates based upon a change in a financial index, such as the Consumer Price Index, the difference between the rate at lease inception and the subsequent fluctuations in that rate are included in variable lease costs. Additionally, because the Company has elected to not separate lease and non-lease components, variable costs also include payments to the landlord for common area maintenance, real estate taxes, insurance and other operating expenses. Lease expense is recognized on a straight-line basis over the lease term, with variable lease payments recognized in the period those payments are incurred. The discount rate implicit within our leases is not readily determinable, and therefore, the Company uses its estimated incremental borrowing rate in determining the present value of lease payments. The incremental borrowing rate is determined based on the Company’s recent debt issuances, lease term and the currency in which lease payments are made. The following table presents the weighted average remaining lease term and discount rate: June 28, Weighted-average remaining lease term of operating leases (in years) 7.7 Weighted-average discount rate of operating leases 5.5 % (11.)

As a result of these lease modifications, the Company re-measured the lease liability and adjusted the ROU asset on the modification dates.

Fair Value Disclosures [Abstract]
FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS	FINANCIAL INSTRUMENTS AND 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 is exposed to global market risks, including the effect of changes in interest rates and foreign currency exchange rates, and uses derivatives to manage these exposures that occur in the normal course of business. The Company does not hold or issue derivatives for trading or speculative purposes. All derivatives are recorded at fair value on the balance sheet. Interest Rate Swaps The Company periodically enters into interest rate swap agreements in order to reduce the cash flow risk caused by interest rate changes on its outstanding floating rate borrowings. Under these swap agreements, the Company pays a fixed rate of interest and receives a floating rate equal to one-month London Interbank Offered Rate (“LIBOR”). The variable rate received from the swap agreements 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 Company has designated these swap agreements as cash flow hedges based on concluding the hedged forecasted transaction is probable of occurring within the period the cash flow hedge is anticipated to affect earnings. The unrealized gains and losses on these contracts are reported in AOCI in the Condensed Consolidated Balance Sheets and are subsequently reclassified into earnings when interest on the related debt is accrued. The fair value of the Company’s swap agreements are 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 receives a fair value estimate from the swap agreement counterparty to verify the reasonableness of the Company’s estimate. The estimated fair value of the swap agreements represents the amount the Company would receive (pay) to terminate the contracts. Information regarding the Company’s outstanding interest rate swaps designated as cash flow hedges as of June 28, 2019 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 2017 Jun 2020 1.1325 % 2.4041 % $ 1,448 Accrued expenses and other current liabilities 200,000 Jun 2020 Jun 2023 2.1785 (a) (2,794 ) Other long-term liabilities 400,000 Apr 2019 Apr 2020 2.4150 2.4185 (1,485 ) Accrued expenses and other current liabilities __________ (a) The interest rate swap is not in effect until June 2020. 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. The unrealized gains and losses on these contracts are reported in AOCI in the Condensed Consolidated Balance Sheets and are reclassified to earnings in the same periods during which the hedged transactions affect earnings. Information regarding outstanding foreign currency forward contracts designated as cash flow hedges as of June 28, 2019 is as follows (dollars in thousands): Notional Amount Start Date End Date $/Foreign Currency Fair Value Balance Sheet Location $ 11,337 Jul 2019 Sep 2019 1.1628 Euro $ (195 ) Prepaid expenses and other current assets 10,499 Jul 2019 Dec 2019 0.0500 Peso 254 Prepaid expenses and other current assets 12,085 Jul 2019 Dec 2019 0.0504 Peso 205 Prepaid expenses and other current assets (14.) FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS (Continued) The fair value of foreign currency contracts are determined through the use of cash flow models that utilize observable market data inputs to estimate fair value. These observable market data inputs include foreign exchange rates and credit spread curves. In addition, the Company receives fair value estimates from the foreign currency contract counterparties to verify the reasonableness of the Company’s estimates. Derivative Instruments with Hedge Accounting Designation The following tables present the fair values of derivative instruments formally designated as hedging instruments as of June 28, 2019 and December 28, 2018 (in thousands).

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. Borrowings under the Company’s Revolving Credit Facility, TLA Facility and TLB Facility accrue interest at a floating rate tied to a standard short-term borrowing index, selected at the Company’s option, plus an applicable margin. The carrying amount of this floating rate debt approximates fair value based upon the respective interest rates adjusting with market rate adjustments. Equity Investments The Company holds long-term, strategic investments in companies to promote business and strategic objectives. These investments are included in Other Long-Term Assets on the Condensed Consolidated Balance Sheets. Non-marketable equity securities are equity securities without readily determinable fair value. The Company has elected the practicability exception to use an alternative approach that measures the securities at cost minus impairment, if any, plus or minus changes resulting from qualifying observable price changes. If an impairment is recognized on the Company’s non-marketable equity securities during the period, these assets are classified as Level 3 within the fair value hierarchy based on the nature of the fair value inputs. Equity investments are comprised of the following (in thousands): June 28, December 28, Equity method investment $ 14,910 $ 15,148 Non-marketable equity securities 6,092 7,667 Total equity investments $ 21,002 $ 22,815 (14.) FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS (Continued) The components of (Gain) Loss on Equity Investments, Net for each period were as follows (in thousands): Three Months Ended Six Months Ended June 28, June 29, June 28, June 29, Equity method investment (income) loss $ 36 $ (284 ) 77 (5,254 ) Impairment charges 1,575 — 1,575 — Observable price adjustments on non-marketable equity securities — — — — Total (gain) loss on equity investments, net $ 1,611 $ (284 ) $ 1,652 $ (5,254 ) In May 2019, the Company determined that an investment in one of its non-marketable equity securities was impaired and determined the fair value to be zero based upon available market information. An impairment charge of $1.6 million was recognized during the second quarter of 2019. This assessment was based on qualitative indications of impairment. Factors that significantly influenced the determination of the impairment loss included the equity security’s investee’s financial condition, priority claims to the equity security, distributions rights and preferences, and status of the regulatory approval required to bring its product to market. The Company’s equity method investment is in a Chinese venture capital fund focused on investing in life sciences companies. As of June 28, 2019 , the Company owned 6.7% of this fund.

Revenue from Contract with Customer [Abstract]
REVENUE FROM CONTRACTS WITH CUSTOMERS	REVENUE FROM CONTRACTS WITH CUSTOMERS Revenue Recognition The majority of the Company’s revenues consist of sales of various medical devices and products to large, multinational OEMs and their affiliated subsidiaries. Revenue is recognized when performance obligations are satisfied and the customer has obtained control of the products. Under the provisions of the majority of the Company’s contracts with customers, revenue is recognized at the point in time when title and risk of ownership transfers to the customer, which is primarily determined based upon the shipping terms. When contracts with customers for products that do not have an alternative use to the Company contain provisions that provide the Company with an enforceable right to payment for performance completed to date with a recapture of costs incurred plus an applicable margin throughout the duration of the contract, revenue is recognized over time as control is deemed to have transferred to the customer. The Company uses an input measure to determine progress towards completion and total estimated costs at completion. Under this method, sales and gross profit are recognized as work is performed generally based on actual costs incurred. For arrangements recognized over time, the Company records a contract asset for unbilled revenue associated with non-cancellable customer orders. Revenue is recognized net of sales tax, value-added taxes and other taxes. 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.

Basis of Presentation (Policies)	6 Months Ended
	Jun. 28, 2019
Accounting Policies [Abstract]
Interim Basis of Accounting	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 28, 2018 . 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.
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 second quarter of 2019 and 2018 each contained 13 weeks and ended on June 28 and June 29,
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. In addition, we continue to explore tax planning opportunities that may have a material impact on our effective tax rate.
Cost And Equity Method Investments	The Company holds long-term, strategic investments in companies to promote business and strategic objectives. These investments are included in Other Long-Term Assets on the Condensed Consolidated Balance Sheets. Non-marketable equity securities
