Accounting Policies [Abstract]
Basis of Accounting [Text Block]	Basis of Presentation The condensed consolidated financial statements included herein have been prepared by PerkinElmer, Inc. (the “Company”), in accordance with accounting principles generally accepted in the United States of America (the “U.S.” or the "United States") and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information in the footnote disclosures of the financial statements has been condensed or omitted where it substantially duplicates information provided in the Company’s latest audited consolidated financial statements, in accordance with the rules and regulations of the SEC. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes included in its Annual Report on Form 10-K for the fiscal year ended January 3, 2016 , filed with the SEC (the “ 2015 Form 10-K”). The balance sheet amounts at January 3, 2016 in this report were derived from the Company’s audited 2015 consolidated financial statements included in the 2015 Form 10-K. The condensed consolidated financial statements reflect all adjustments that, in the opinion of management, are necessary to present fairly the Company’s financial position, results of operations and cash flows for the periods indicated. The preparation of financial statements in conformity with U.S. Generally Accepted Accounting Principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts and classifications of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The results of operations for the three and six months ended July 3, 2016 and June 28, 2015 , respectively, are not necessarily indicative of the results for the entire fiscal year or any future period. The Company has evaluated subsequent events from July 3, 2016 through the date of the issuance of these condensed consolidated financial statements and has determined that other than the events the Company has disclosed within the footnotes to the financial statements, no material subsequent events have occurred that would affect the information presented in these condensed consolidated financial statements or would require additional disclosure. The Company’s fiscal year ends on the Sunday nearest December 31. The Company reports fiscal years under a 52/53 week format and as a result, certain fiscal years will contain 53 weeks. The fiscal year ending January 1, 2017 (" fiscal year 2016 ") will include 52 weeks, while the fiscal year ended January 3, 2016 (" fiscal year 2015 ") included 53 weeks. The additional week in fiscal year 2015 was reflected in the Company's third quarter, which consisted of 14 weeks as compared to the Company's third quarter of fiscal year 2016, which will consist of 13 weeks. Recently Adopted and Issued Accounting Pronouncements: From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (the "FASB") and are adopted by the Company as of the specified effective dates. Unless otherwise discussed, such pronouncements did not have or will not have a significant impact on the Company’s condensed consolidated financial position, results of operations and cash flows or do not apply to the Company’s operations. In March 2016, the FASB issued Accounting Standards Update No. 2016-09, Compensation—Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting ("ASU No. 2016-09"). The new standard simplifies the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory withholding requirements, as well as the related classification in the statement of cash flows. The new standard is effective for annual reporting periods beginning after December 15, 2016, and interim periods within those years, with early adoption permitted. The standard requires an entity to recognize all excess tax benefits and tax deficiencies as income tax benefit or expense in the income statement as discrete items in the reporting period in which they occur, and such tax benefits and tax deficiencies are not included in the estimate of an entity’s annual effective tax rate, applied on a prospective basis. Further, the standard eliminates the requirement to defer the recognition of excess tax benefits until the benefit is realized through a reduction to taxes payable. All excess tax benefits previously unrecognized, along with any valuation allowance, should be recognized on a modified retrospective basis as a cumulative adjustment to retained earnings as of the date of adoption. Under ASU No. 2016-09, an entity that applies the treasury stock method in calculating diluted earnings per share is required to exclude excess tax benefits and deficiencies from the calculation of assumed proceeds since such amounts are recognized in the income statement. Excess tax benefits should also be classified as operating activities in the same manner as other cash flows related to income taxes on the statement of cash flows, as such excess tax benefits no longer represent financing activities since they are recognized in the income statement, and should be applied prospectively or retrospectively to all periods presented. The Company adopted ASU No. 2016-09 at the beginning of the first quarter of fiscal year 2016. The Company recorded a cumulative increase of $14.2 million in the beginning of the first quarter of fiscal year 2016 retained earnings with a corresponding increase in deferred tax assets related to the prior years' unrecognized excess tax benefits. Excess tax benefits related to exercised options and vested restricted stock and restricted stock units during the six months ended July 3, 2016 have been recognized in the current period’s income statement. The Company also excluded the excess tax benefits from the calculation of diluted earnings per share for the three and six months ended July 3, 2016 . The Company applied the cash flow presentation section of the guidance on a prospective basis, and the prior period statement of cash flows was not adjusted. ASU No. 2016-09 also allows an entity to elect as an accounting policy either to continue to estimate the total number of awards for which the requisite service period will not be rendered or to account for forfeitures for service based awards as they occur. An entity that elects to account for forfeitures as they occur should apply the accounting change on a modified retrospective basis as a cumulative effect adjustment to retained earnings as of the date of adoption. The Company has elected to account for forfeitures as they occur. The adoption of this accounting policy did not have a material impact on the Company’s consolidated financial position, results of operations and cash flows. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases . The new guidance requires lessees to recognize a lease liability and right-of-use asset on the balance sheet for financing and operating leases. The provisions of this guidance are to be applied using a modified retrospective approach and are effective for annual reporting periods beginning after December 15, 2018, and interim periods within those years, with early adoption permitted. The Company is evaluating the requirements of this guidance and has not yet determined the impact of its adoption on the Company's consolidated financial position, results of operations and cash flows. In July 2015, the FASB issued Accounting Standards Update No. 2015-11, Simplifying the Measurement of Inventory . Under this new guidance, companies that use inventory measurement methods other than last-in, first-out or the retail inventory method should measure inventory at the lower of cost and net realizable value. The provisions of this guidance are to be applied prospectively and are effective for interim and annual reporting periods beginning after December 15, 2016, with early adoption permitted. The Company is evaluating the requirements of this guidance. The adoption is not expected to have a material impact on the Company’s consolidated financial position, results of operations and cash flows. In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). Under this new guidance, an entity should use a five-step process to recognize revenue, depicting the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard also requires new disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Subsequent to the issuance of the standard, the FASB decided to defer the effective date for one year to annual reporting periods beginning after December 15, 2017, with early adoption permitted for annual reporting periods beginning after December 15, 2016. In May 2016, the FASB also issued Accounting Standards Update No. 2016-12, Revenue from Contracts with Customers (Topic 606), Narrow-Scope Improvements and Practical Expedients ("ASU 2016-12") , which amended its revenue recognition guidance in ASU 2014-09 on transition, collectibility, non-cash consideration and the presentation of sales and other similar taxes. In April 2016, the FASB also issued Accounting Standards Update No. 2016-10, Revenue from Contracts with Customers (Topic 606), Identifying Performance Obligations and Licensing ("ASU 2016-10") , which amended its revenue recognition guidance in ASU 2014-09 on identifying performance obligations to allow entities to disregard items that are immaterial in the context of the contract, clarify when a promised good or service is separately identifiable (i.e., distinct within the context of the contract) and allow an entity to elect to account for the cost of shipping and handling performed after control of a good has been transferred to the customer as a fulfillment cost (i.e., an expense). ASU 2016-10 also clarifies how an entity should evaluate the nature of its promise in granting a license of intellectual property ("IP") and requires entities to classify IP in one of two categories: functional IP or symbolic IP, which will determine whether it recognizes revenue over time or at a point in time. ASU 2016-10 also address how entities should consider license renewals and restrictions and apply the exception for sales- and usage-based royalties received in exchange for licenses of IP. ASU 2016-12, ASU 2016-10 and ASU 2014-09 may be adopted either using a full retrospective approach or a modified retrospective approach. The Company is evaluating the requirements of the foregoing standards and has not yet determined the transition method to use or the impact of their adoption on the Company’s consolidated financial position, results of operations and cash flows. The Company does not intend to early adopt these standards.

Business Combinations [Abstract]
Business Combinations	Business Combinations Acquisitions in fiscal year 2016 During the first six months of fiscal year 2016, the Company completed the acquisition of a business for total consideration of $8.8 million in cash. The excess of the purchase price over the fair value of the acquired business's net assets represents cost and revenue synergies specific to the Company, as well as non-capitalizable intangible assets, such as the employee workforce acquired. As a result of the acquisition, the Company recorded goodwill of $3.7 million , which is not tax deductible, and intangible assets of $2.0 million . The Company has reported the operations for this acquisition within the results of the Company's Environmental Health segment from the acquisition date. Identifiable definite-lived intangible assets, such as core technology and trade name, acquired as part of this acquisition had weighted average amortization periods of 11 years . Subsequent to July 3, 2016, the Company completed the acquisition of a business for total consideration of $61.0 million in cash, net of cash acquired, as of the closing date. The operations for this acquisition will be reported within the results of the Company's Human Health and Environment Health segments from the acquisition date. Acquisitions in fiscal year 2015 During fiscal year 2015, the Company completed the acquisition of five businesses for a total consideration of $77.1 million in cash. The acquired businesses included Vanadis Diagnostics AB (“Vanadis”), which was acquired for total consideration of $35.1 million in cash, as further described in Note 17 below, and other acquisitions for aggregate consideration of $42.0 million in cash. The Company has a potential obligation to pay the shareholders of Vanadis additional contingent consideration of up to $93.0 million , which at closing had an estimated fair value of $56.9 million . The excess of the purchase prices over the fair values of each of the acquired business's net assets represents cost and revenue synergies specific to the Company, as well as non-capitalizable intangible assets, such as the employee workforce acquired, and has been allocated to goodwill, of which $9.2 million is tax deductible. The Company has reported the operations for these acquisitions within the results of the Company’s Human Health and Environmental Health segments from the acquisition dates. Identifiable definite-lived intangible assets, such as core technology and trade names, acquired as part of these acquisitions had weighted average amortization periods of nine years . The total purchase price for the acquisitions in fiscal year 2015 has been allocated to the estimated fair values of assets acquired and liabilities assumed as follows: 2015 Acquisitions (In thousands) Fair value of business combination: Cash payments $ 75,285 Contingent consideration 56,878 Working capital and other adjustments 1,832 Less: cash acquired (3,864 ) Total $ 130,131 Identifiable assets acquired and liabilities assumed: Current assets $ 2,551 Property, plant and equipment 998 Identifiable intangible assets: Core technology 15,759 Trade names 200 Licenses 116 Customer relationships 3,073 In-process research and development ("IPR&D") 75,700 Goodwill 51,356 Deferred taxes (16,772 ) Liabilities assumed (2,850 ) Total $ 130,131 The preliminary allocations of the purchase prices for acquisitions are based upon initial valuations. The Company's estimates and assumptions underlying the initial valuations are subject to the collection of information necessary to complete its valuations within the measurement periods, which are up to one year from the respective acquisition dates. The primary areas of the preliminary purchase price allocations that are not yet finalized relate to the fair value of certain tangible and intangible assets acquired and liabilities assumed, assets and liabilities related to income taxes and related valuation allowances, and residual goodwill. The Company expects to continue to obtain information to assist in determining the fair values of the net assets acquired at the acquisition dates during the measurement periods. During the measurement periods, the Company will adjust assets or liabilities if new information is obtained about facts and circumstances that existed as of the acquisition dates that, if known, would have resulted in the recognition of those assets and liabilities as of those dates. These adjustments will be made in the periods in which the amounts are determined and the cumulative effect of such adjustments will be calculated as if the adjustments had been completed as of the acquisition dates. All changes that do not qualify as adjustments made during the measurement periods are also included in current period earnings. Allocations of the purchase price for acquisitions are based on estimates of the fair value of the net assets acquired and are subject to adjustment upon finalization of the purchase price allocations. The accounting for business combinations requires estimates and judgments as to expectations for future cash flows of the acquired business, and the allocation of those cash flows to identifiable intangible assets, in determining the estimated fair values for assets acquired and liabilities assumed. The fair values assigned to tangible and intangible assets acquired and liabilities assumed, including contingent consideration, are based on management’s estimates and assumptions, as well as other information compiled by management, including valuations that utilize customary valuation procedures and techniques. Contingent consideration is measured at fair value at the acquisition date, based on the probability that revenue thresholds or product development milestones will be achieved during the earnout period, with changes in the fair value after the acquisition date affecting earnings to the extent it is to be settled in cash. Increases or decreases in the fair value of contingent consideration liabilities primarily result from changes in the estimated probabilities of achieving revenue thresholds, changes in discount rates or product development milestones during the earnout period. As of July 3, 2016 , the Company may have to pay contingent consideration related to acquisitions with open contingency periods of up to $94.6 million . As of July 3, 2016 , the Company has recorded contingent consideration obligations with an estimated fair value of $62.9 million , of which $9.7 million was recorded in accrued expenses and other current liabilities, and $53.2 million was recorded in long-term liabilities. As of January 3, 2016 , the Company had recorded contingent consideration obligations with an estimated fair value of $57.4 million , of which $9.4 million was recorded in accrued expenses and other current liabilities, and $48.0 million was recorded in long-term liabilities. The expected maximum earnout period for acquisitions with open contingency periods does not exceed six years from the respective acquisition dates, and the remaining weighted average expected earnout period at July 3, 2016 was two years . If the actual results differ from the estimates and judgments used in these fair values, the amounts recorded in the condensed consolidated financial statements could result in a possible impairment of the intangible assets and goodwill, require acceleration of the amortization expense of definite-lived intangible assets or the recognition of additional contingent consideration which would be recognized as a component of operating expenses from continuing operations. Total transaction costs related to acquisition activities for the three and six months ended July 3, 2016 were $0.2 million and $0.5 million , respectively. Total transaction costs related to acquisition activities for the three and six months ended June 28, 2015 were $0.2 million and $0.4 million , respectively. These transaction costs were expensed as incurred and recorded in selling, general and administrative expenses in the Company's condensed consolidated statements of operations.

Discontinued Operations

Discontinued Operations	6 Months Ended

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	As part of the Company’s continuing efforts to focus on higher growth opportunities, the Company has discontinued certain businesses. The Company has accounted for these businesses as discontinued operations and, accordingly, has presented the results of operations and related cash flows as discontinued operations for all periods presented. Any remaining assets and liabilities of these businesses have been presented separately, and are reflected within assets and liabilities from discontinued operations in the accompanying condensed consolidated balance sheets as of July 3, 2016 and January 3, 2016 . During the first six months of each of fiscal years 2016 and 2015 , the Company settled various commitments related to the divestiture of discontinued operations and recognized pre-tax losses of $0.01 million and $0.02 million , respectively. The Company recorded a tax benefit of $2.6 million on discontinued operations and dispositions for each of the three and six months ended July 3, 2016 . The Company recorded a tax provision of $0.05 million and $0.03 million on discontinued operations and dispositions for the three and six months ended June 28, 2015 , respectively. During the second quarter of 2016, the Company completed the sale of its investment in PerkinElmer Labs, Inc., recognizing a pre-tax gain of $7.1 million . The sale generated a capital loss for tax purposes of $7.3 million , which resulted in an income tax benefit of $2.5 million that was recognized as a discrete benefit during the second quarter of 2016.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company regularly reviews its tax positions in each significant taxing jurisdiction in the process of evaluating its unrecognized tax benefits. The Company makes adjustments to its unrecognized tax benefits when: (i) facts and circumstances regarding a tax position change, causing a change in management’s judgment regarding that tax position; (ii) a tax position is effectively settled with a tax authority at a differing amount; and/or (iii) the statute of limitations expires regarding a tax position. At July 3, 2016 , the Company had gross tax effected unrecognized tax benefits of $28.2 million , of which $26.5 million , if recognized, would affect the continuing operations effective tax rate. The remaining amount, if recognized, would affect discontinued operations. The Company believes that it is reasonably possible that approximately $1.8 million of its uncertain tax positions at July 3, 2016 , including accrued interest and penalties, and net of tax benefits, may be resolved over the next twelve months as a result of lapses in applicable statutes of limitations and potential settlements. Various tax years after 2009 remain open to examination by certain jurisdictions in which the Company has significant business operations, such as Finland, Germany, Italy, Netherlands, Singapore, the United Kingdom and the United States. The tax years under examination vary by jurisdiction. During the first six months of fiscal years 2016 and 2015 , the Company recorded net discrete income tax benefit s of $5.4 million and $2.8 million , respectively. The discrete tax benefit in the first six months of fiscal year 2016 includes tax benefits from the sale of a subsidiary.

Debt Disclosure [Abstract]
Debt	Debt Senior Unsecured Revolving Credit Facility. The Company's senior unsecured revolving credit facility provides for $700.0 million of revolving loans and has an initial maturity of January 8, 2019 . As of July 3, 2016 , undrawn letters of credit in the aggregate amount of $11.5 million were treated as issued and outstanding when calculating the borrowing availability under the senior unsecured revolving credit facility. As of July 3, 2016 , the Company had $161.5 million available for additional borrowing under the facility. The Company uses the senior unsecured revolving credit facility for general corporate purposes, which may include working capital, refinancing existing indebtedness, capital expenditures, share repurchases, acquisitions and strategic alliances. The interest rates under the senior unsecured revolving credit facility are based on the Eurocurrency rate or the base rate at the time of borrowing, plus a margin. The base rate is the higher of (i) the rate of interest in effect for such day as publicly announced from time to time by JP Morgan Chase Bank, N.A. as its "prime rate," (ii) the Federal Funds rate plus 50 basis points or (iii) one-month Libor plus 1.00%. At July 3, 2016 , borrowings under the senior unsecured revolving credit facility were accruing interest primarily based on the Eurocurrency rate. The Eurocurrency margin as of July 3, 2016 was 108 basis points. The weighted average Eurocurrency interest rate as of July 3, 2016 was 0.50% , resulting in a weighted average effective Eurocurrency rate, including the margin, of 1.58% . As of July 3, 2016 , the senior unsecured revolving credit facility had an aggregate carrying value of $525.0 million , which was net of $2.0 million of unamortized debt issuance costs. As of January 3, 2016 , the senior unsecured revolving credit facility had an aggregate carrying value of $479.6 million , which was net of $2.4 million of unamortized debt issuance costs. The credit agreement for the facility contains affirmative, negative and financial covenants and events of default. The financial covenants in the Company's senior unsecured revolving credit facility include a debt-to-capital ratio, and two contingent covenants, a maximum consolidated leverage ratio and a minimum consolidated interest coverage ratio, applicable if the Company's credit rating is downgraded below investment grade. On July 19, 2016 , the Company repaid in full the outstanding balance of the senior unsecured revolving credit facility, thereby increasing the borrowing availability from $161.5 million as of July 3, 2016 to $688.5 million as of July 19, 2016 . As previously disclosed in connection with the Company’s issuance on July 19, 2016 of €500.0 million aggregate principal amount of senior unsecured notes due in 2026, the Company expects to terminate the current senior unsecured revolving credit facility and enter into a new senior unsecured revolving credit facility with a five year term and an expansion of borrowing capacity from $700.0 million to $1.0 billion. 5% Senior Unsecured Notes due in 2021. On October 25, 2011, the Company issued $500.0 million aggregate principal amount of senior unsecured notes due in 2021 (the “2021 Notes”) in a registered public offering and received $496.9 million of net proceeds from the issuance. The 2021 Notes were issued at 99.372% of the principal amount, which resulted in a discount of $3.1 million . As of July 3, 2016 , the 2021 Notes had an aggregate carrying value of $495.4 million , net of $1.9 million of unamortized original issue discount and $2.7 million of unamortized debt issuance costs. As of January 3, 2016 , the 2021 Notes had an aggregate carrying value of $495.1 million , net of $2.0 million of unamortized original issue discount and $2.9 million of unamortized debt issuance costs. The 2021 Notes mature in November 2021 and bear interest at an annual rate of 5% . Interest on the 2021 Notes is payable semi-annually on May 15th and November 15th each year. Prior to August 15, 2021 (three months prior to their maturity date), the Company may redeem the 2021 Notes in whole or in part, at its option, at a redemption price equal to the greater of (i) 100% of the principal amount of the 2021 Notes to be redeemed, plus accrued and unpaid interest, or (ii) the sum of the present values of the remaining scheduled payments of principal and interest in respect to the 2021 Notes being redeemed, discounted on a semi-annual basis, at the Treasury Rate plus 45 basis points, plus accrued and unpaid interest. At any time on or after August 15, 2021 (three months prior to their maturity date), the Company may redeem the 2021 Notes, at its option, at a redemption price equal to 100% of the principal amount of the 2021 Notes to be redeemed plus accrued and unpaid interest. Upon a change of control (as defined in the indenture governing the 2021 Notes) and a contemporaneous downgrade of the 2021 Notes below investment grade, each holder of 2021 Notes will have the right to require the Company to repurchase such holder's 2021 Notes for 101% of their principal amount, plus accrued and unpaid interest. Financing Lease Obligations. In fiscal year 2012, the Company entered into agreements with the lessors of certain buildings that the Company is currently occupying and leasing to expand those buildings. The Company provided a portion of the funds needed for the construction of the additions to the buildings, and as a result the Company was considered the owner of the buildings during the construction period. At the end of the construction period, the Company was not reimbursed by the lessors for all of the construction costs. The Company is therefore deemed to have continuing involvement and the leases qualify as financing leases under sale-leaseback accounting guidance, representing debt obligations for the Company and non-cash investing and financing activities. As a result, the Company capitalized $29.3 million in property, plant and equipment, net, representing the fair value of the buildings with a corresponding increase to debt. The Company has also capitalized $11.5 million in additional construction costs necessary to complete the renovations to the buildings, which were funded by the lessors, with a corresponding increase to debt. At July 3, 2016 , the Company had $37.6 million recorded for these financing lease obligations, of which $1.1 million was recorded as short-term debt and $36.5 million was recorded as long-term debt. At January 3, 2016 , the Company had $38.2 million recorded for these financing lease obligations, of which $1.1 million was recorded as short-term debt and $37.1 million was recorded as long-term debt. The buildings are being depreciated on a straight-line basis over the terms of the leases to their estimated residual values, which will equal the remaining financing obligation at the end of the lease term. At the end of the lease term, the remaining balances in property, plant and equipment, net and debt will be reversed against each other. 1.875% Senior Unsecured Notes due 2026. On July 19, 2016, the Company issued €500.0 million aggregate principal amount of senior unsecured notes due in 2026 (the “2026 Notes”) in a registered public offering and received approximately €492.3 million of net proceeds from the issuance. The 2026 Notes were issued at 99.118% of the principal amount, which resulted in a discount of €4.4 million . The 2026 Notes mature in July 2026 and bear interest at an annual rate of 1.875% . Interest on the 2026 Notes is payable annually on July 19th each year. The proceeds from the 2026 Notes were used to pay in full the outstanding balance of the Company's senior unsecured revolving credit facility. Prior to April 19, 2026 (three months prior to their maturity date), the Company may redeem the 2026 Notes in whole at any time or in part from time to time, at its option, at a redemption price equal to the greater of (i) 100% of the principal amount of the 2026 Notes to be redeemed, or (ii) the sum of the present values of the remaining scheduled payments of principal and interest in respect to the 2026 Notes being redeemed, discounted on an annual basis, at the applicable Comparable Government Bond Rate (as defined in the indenture governing the 2026 Notes) plus 35 basis points; plus, in each case, accrued and unpaid interest. In addition, at any time on or after April 19, 2026 (three months prior to their maturity date), the Company may redeem the 2026 Notes, at its option, at a redemption price equal to 100% of the principal amount of the 2026 Notes due to be redeemed plus accrued and unpaid interest. Upon a change of control (as defined in the indenture governing the 2026 Notes) and a contemporaneous downgrade of the 2026 Notes below investment grade, the Company will, in certain circumstances, make an offer to purchase the 2026 Notes at a price equal to 101% of their principal amount plus any accrued and unpaid interest.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per share was computed by dividing net income by the weighted-average number of common shares outstanding during the period less restricted unvested shares. Diluted earnings per share was computed by dividing net income by the weighted-average number of common shares outstanding plus all potentially dilutive common stock equivalents, primarily shares issuable upon the exercise of stock options using the treasury stock method. The following table reconciles the number of shares utilized in the earnings per share calculations: Three Months Ended Six Months Ended July 3, June 28, July 3, June 28, (In thousands) Number of common shares—basic 108,970 113,018 109,690 112,829 Effect of dilutive securities: Stock options 688 639 675 659 Restricted stock awards 186 176 155 148 Number of common shares—diluted 109,844 113,833 110,520 113,636 Number of potentially dilutive securities excluded from calculation due to antidilutive impact 250 493 674 713 Antidilutive securities include outstanding stock options with exercise prices and average unrecognized compensation cost in excess of the average fair market value of common stock for the related period. Antidilutive options were excluded from the calculation of diluted net income per share and could become dilutive in the future.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets, Net	Goodwill and Intangible Assets, Net The Company tests goodwill and non-amortizing intangible assets at least annually for possible impairment. Accordingly, the Company completes the annual testing of impairment for goodwill and non-amortizing intangible assets on the later of January 1 or the first day of each fiscal year. In addition to its annual test, the Company regularly evaluates whether events or circumstances have occurred that may indicate a potential impairment of goodwill or non-amortizing intangible assets. The process of testing goodwill for impairment involves the determination of the fair value of the applicable reporting units. The test consists of a two-step process. The first step is the comparison of the fair value to the carrying value of the reporting unit to determine if the carrying value exceeds the fair value. The second step measures the amount of an impairment loss, and is only performed if the carrying value exceeds the fair value of the reporting unit. The Company performed its annual impairment testing for its reporting units as of January 4, 2016 , its annual impairment date for fiscal year 2016 . The Company concluded based on the first step of the process that there was no goodwill impairment, and the fair value exceeded the carrying value by more than 20.0% for each reporting unit. The long-term terminal growth rate for the Company’s reporting units was 3.0% for the fiscal year 2016 impairment analysis. The range for the discount rates for the reporting units was 9.5% to 12.5% . Keeping all other variables constant, a 10.0% change in any one of these input assumptions for the various reporting units would still allow the Company to conclude, based on the first step of the process, that there was no impairment of goodwill. The Company has consistently employed the income approach to estimate the current fair value when testing for impairment of goodwill. A number of significant assumptions and estimates are involved in the application of the income approach to forecast operating cash flows, including markets and market share, sales volumes and prices, costs to produce, tax rates, capital spending, discount rates and working capital changes. Cash flow forecasts are based on approved business unit operating plans for the early years’ cash flows and historical relationships in later years. The income approach is sensitive to changes in long-term terminal growth rates and the discount rates. The long-term terminal growth rates are consistent with the Company’s historical long-term terminal growth rates, as the current economic trends are not expected to affect the long-term terminal growth rates of the Company. The Company corroborates the income approach with a market approach. The Company has consistently employed the relief from royalty model to estimate the current fair value when testing for impairment of non-amortizing intangible assets. The impairment test consists of a comparison of the fair value of the non-amortizing intangible asset with its carrying amount. If the carrying amount of a non-amortizing intangible asset exceeds its fair value, an impairment loss in an amount equal to that excess is recognized . In addition, the Company evaluates the remaining useful lives of its non-amortizing intangible assets at least annually to determine whether events or circumstances continue to support an indefinite useful life. If events or circumstances indicate that the useful lives of non-amortizing intangible assets are no longer indefinite, the assets will be tested for impairment. These intangible assets will then be amortized prospectively over their estimated remaining useful lives and accounted for in the same manner as other intangible assets that are subject to amortization. The Company performed its annual impairment testing as of January 4, 2016 , and concluded that there was no impairment of non-amortizing intangible assets. An assessment of the recoverability of amortizing intangible assets takes place when events have occurred that may give rise to an impairment. No such events occurred during the first six months of fiscal year 2016 . The changes in the carrying amount of goodwill for the six months ended July 3, 2016 were as follows: Human Health Environmental Health Consolidated (In thousands) Balance at January 3, 2016 $ 1,672,491 $ 603,658 $ 2,276,149 Foreign currency translation 266 65 331 Disposition of businesses (7,923 ) — (7,923 ) Acquisitions and other (28 ) 3,673 3,645 Balance at July 3, 2016 $ 1,664,806 $ 607,396 $ 2,272,202 Identifiable intangible asset balances at July 3, 2016 and January 3, 2016 by category were as follows: July 3, January 3, (In thousands) Patents $ 39,921 $ 39,911 Less: Accumulated amortization (31,113 ) (29,788 ) Net patents 8,808 10,123 Trade names and trademarks 40,429 40,249 Less: Accumulated amortization (22,445 ) (20,686 ) Net trade names and trademarks 17,984 19,563 Licenses 59,137 58,969 Less: Accumulated amortization (47,477 ) (45,286 ) Net licenses 11,660 13,683 Core technology 309,935 307,242 Less: Accumulated amortization (226,752 ) (211,829 ) Net core technology 83,183 95,413 Customer relationships 383,378 391,566 Less: Accumulated amortization (201,960 ) (191,655 ) Net customer relationships 181,418 199,911 IPR&D 85,462 85,679 Less: Accumulated amortization (4,692 ) (4,145 ) Net IPR&D 80,770 81,534 Net amortizable intangible assets 383,823 420,227 Non-amortizing intangible assets: Trade names 70,584 70,584 Total $ 454,407 $ 490,811 Total amortization expense related to definite-lived intangible assets was $18.9 million and $37.9 million for the three and six months ended July 3, 2016 , respectively, and $19.9 million and $39.7 million for the three and six months June 28, 2015 , respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	Derivatives and Hedging Activities The Company uses derivative instruments as part of its risk management strategy only, and includes derivatives utilized as economic hedges that are not designated as hedging instruments. By nature, all financial instruments involve market and credit risks. The Company enters into derivative instruments with major investment grade financial institutions and has policies to monitor the credit risk of those counterparties. The Company does not enter into derivative contracts for trading or other speculative purposes, nor does the Company use leveraged financial instruments. Approximately 60% of the Company’s business is conducted outside of the United States, generally in foreign currencies. As a result, fluctuations in foreign currency exchange rates can increase the costs of financing, investing and operating the business. In the ordinary course of business, the Company enters into foreign exchange contracts for periods consistent with its committed exposures to mitigate the effect of foreign currency movements on transactions denominated in foreign currencies. The intent of these economic hedges is to offset gains and losses that occur on the underlying exposures from these currencies, with gains and losses resulting from the forward currency contracts that hedge these exposures. Transactions covered by hedge contracts include intercompany and third-party receivables and payables. The contracts are primarily in European and Asian currencies, have maturities that do not exceed 12 months, have no cash requirements until maturity, and are recorded at fair value on the Company’s condensed consolidated balance sheets. The unrealized gains and losses on the Company’s foreign currency contracts are recognized immediately in interest and other expense, net. The cash flows related to the settlement of these hedges are included in cash flows from operating activities within the Company’s condensed consolidated statement of cash flows. Principal hedged currencies include the British Pound, Euro, Japanese Yen and Singapore Dollar. The Company held forward foreign exchange contracts, designated as economic hedges, with U.S. dollar equivalent notional amounts totaling $131.5 million , $127.3 million and $101.6 million at July 3, 2016 , January 3, 2016 and June 28, 2015 , respectively, and the fair value of these foreign currency derivative contracts was insignificant. The gains and losses realized on these foreign currency derivative contracts are not material. The duration of these contracts was generally 30 days or less during each of the six months ended July 3, 2016 and June 28, 2015 . In addition, in connection with certain intercompany loan agreements utilized to finance its acquisitions and stock repurchase program, the Company enters into forward foreign exchange contracts intended to hedge movements in foreign exchange rates prior to settlement of such intercompany loans denominated in foreign currencies. The Company records these hedges at fair value on the Company’s condensed consolidated balance sheets. The unrealized gains and losses on these hedges, as well as the gains and losses associated with the remeasurement of the intercompany loans, are recognized immediately in interest and other expense, net. The cash flows related to the settlement of these hedges are included in cash flows from financing activities within the Company’s condensed consolidated statement of cash flows. As of July 3, 2016 , the outstanding forward exchange contracts designated as economic hedges, that were intended to hedge movements in foreign exchange rates prior to the settlement of certain intercompany loan agreements included combined Euro notional amounts of €45.4 million and combined U.S. Dollar notional amounts of $10.2 million . The combined Euro notional amounts of these outstanding hedges was €107.4 million and €156.1 million as of January 3, 2016 and June 28, 2015 , respectively. The net gains and losses on these derivatives, combined with the gains and losses on the remeasurement of the hedged intercompany loans were not material for each of the three and six months ended July 3, 2016 and June 28, 2015 . The Company received $1.3 million and $23.5 million during the six months ended July 3, 2016 and June 28, 2015 , respectively, from the settlement of these hedges. On July 19, 2016, in connection with the issuance of the 2026 Notes, the Company designated the 2026 Notes to hedge its investments in certain foreign subsidiaries. Realized and unrealized translation adjustments from these hedges will be included in the foreign currency translation component of accumulated other comprehensive income ("AOCI"), as well as to offset translation adjustments on the underlying net assets of foreign subsidiaries. The cumulative translation gains or losses will remain in AOCI until the foreign subsidiaries are liquidated or sold. As of July 19, 2016, €495.6 million in foreign currency denominated debt was designated to hedge investments in foreign subsidiaries. The Company does no t expect any material net pre-tax gains or losses to be reclassified from accumulated other comprehensive loss into interest and other expense, net within the next twelve months.

Fair Value Measurements

Fair Value Measurements	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash equivalents, derivatives, marketable securities and accounts receivable. The Company believes it had no significant concentrations of credit risk as of July 3, 2016 . The Company uses the market approach technique to value its financial instruments and there were no changes in valuation techniques during the six months ended July 3, 2016 . The Company’s financial assets and liabilities carried at fair value are primarily comprised of marketable securities, derivative contracts used to hedge the Company’s currency risk, and acquisition-related contingent consideration. The Company has not elected to measure any additional financial instruments or other items at fair value. Valuation Hierarchy: The following summarizes the three levels of inputs required to measure fair value. For Level 1 inputs, the Company utilizes quoted market prices as these instruments have active markets. For Level 2 inputs, the Company utilizes quoted market prices in markets that are not active, broker or dealer quotations, or utilizes alternative pricing sources with reasonable levels of price transparency. For Level 3 inputs, the Company utilizes unobservable inputs based on the best information available, including estimates by management primarily based on information provided by third-party fund managers, independent brokerage firms and insurance companies. A financial asset’s or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The following tables show the assets and liabilities carried at fair value measured on a recurring basis as of July 3, 2016 and January 3, 2016 classified in one of the three classifications described above: Fair Value Measurements at July 3, 2016 Using: Total Carrying Value at July 3, 2016 Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable (Level 3) (In thousands) Marketable securities $ 1,448 $ 1,448 $ — $ — Foreign exchange derivative assets 710 — 710 — Foreign exchange derivative liabilities (1,708 ) — (1,708 ) — Contingent consideration (62,878 ) — — (62,878 ) Fair Value Measurements at January 3, 2016 Using: Total Carrying Value at January 3, 2016 Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (In thousands) Marketable securities $ 1,586 $ 1,586 $ — $ — Foreign exchange derivative assets 2,659 — 2,659 — Foreign exchange derivative liabilities (442 ) — (442 ) — Contingent consideration (57,350 ) — — (57,350 ) Level 1 and Level 2 Valuation Techniques: The Company’s Level 1 and Level 2 assets and liabilities are comprised of investments in equity and fixed-income securities as well as derivative contracts. For financial assets and liabilities that utilize Level 1 and Level 2 inputs, the Company utilizes both direct and indirect observable price quotes, including common stock price quotes, foreign exchange forward prices and bank price quotes. Below is a summary of valuation techniques for Level 1 and Level 2 financial assets and liabilities. Marketable securities: Include equity and fixed-income securities measured at fair value using the quoted market prices in active markets at the reporting date. Foreign exchange derivative assets and liabilities: Include foreign exchange derivative contracts that are valued using quoted forward foreign exchange prices at the reporting date. The Company’s foreign exchange derivative contracts are subject to master netting arrangements that allow the Company and its counterparties to net settle amounts owed to each other. Derivative assets and liabilities that can be net settled under these arrangements have been presented in the Company's condensed consolidated balance sheet on a net basis and are recorded in other assets. As of both July 3, 2016 and January 3, 2016 , none of the master netting arrangements involved collateral. Level 3 Valuation Techniques: The Company’s Level 3 liabilities are comprised of contingent consideration related to acquisitions. For liabilities that utilize Level 3 inputs, the Company uses significant unobservable inputs. Below is a summary of valuation techniques for Level 3 liabilities. Contingent consideration: Contingent consideration is measured at fair value at the acquisition date using projected milestone dates, discount rates, probabilities of success and projected revenues (for revenue-based considerations). Projected risk-adjusted contingent payments are discounted back to the current period using a discounted cash flow model. During fiscal year 2015, the Company acquired certain assets and assumed certain liabilities from Vanadis. Under the terms of the acquisition, the initial purchase consideration was $32.0 million , net of cash and the Company will be obligated to make potential future milestone payments, based on completion of a proof of concept, regulatory approvals and product sales, of up to $93.0 million ranging from 2016 to 2019. The fair value of the contingent consideration as of the acquisition date was estimated at $56.9 million . During the second quarter of fiscal year 2016 , the Company updated the fair value of the contingent consideration and recorded a liability of $62.6 million as of July 3, 2016 . The key assumptions used to determine the fair value of the contingent consideration as of July 3, 2016 included projected milestone dates of 2016 to 2019 , discount rates ranging from 2.3% to 9.8% , conditional probabilities of success of each individual milestone ranging from 85% to 95% and cumulative probabilities of success for each individual milestone ranging from 56% to 95% . A significant delay in the product development (including projected regulatory milestone) achievement date in isolation could result in a significantly lower fair value measurement; a significant acceleration in the product development (including projected regulatory milestone) achievement date in isolation would not have a material impact on the fair value measurement; a significant change in the discount rate in isolation would not have a material impact on the fair value measurement; and a significant change in the probabilities of success in isolation could result in a significant change in fair value measurement. The fair values of contingent consideration are calculated on a quarterly basis based on a collaborative effort of the Company’s regulatory, research and development, operations, finance and accounting groups, as appropriate. Potential valuation adjustments are made as additional information becomes available, including the progress towards completion of a proof of concept, regulatory approvals and product sales as compared to initial projections, the impact of market competition and market landscape shifts from non-invasive prenatal testing products, with the impact of such adjustments being recorded in the Company's consolidated statements of operations. As of July 3, 2016 , the Company may have to pay contingent consideration related to acquisitions with open contingency periods of up to $94.6 million . The expected maximum earnout period for acquisitions with open contingency periods does not exceed six years from the respective acquisition dates, and the remaining weighted average earnout period at July 3, 2016 was two years . A reconciliation of the beginning and ending Level 3 net liabilities for contingent consideration is as follows: Three Months Ended Six Months Ended July 3, June 28, July 3, June 28, (In thousands) Balance at beginning of period $ (58,579 ) $ (81 ) $ (57,350 ) $ (91 ) Additions — (475 ) — (475 ) Amounts paid and foreign currency translation 6 — 100 10 Change in fair value (included within selling, general and administrative expenses) (4,305 ) 81 (5,628 ) 81 Balance at end of period $ (62,878 ) $ (475 ) $ (62,878 ) $ (475 ) The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate fair value due to the short-term maturities of these assets and liabilities. If measured at fair value, cash and cash equivalents would be classified as Level 1. As of July 3, 2016 , the Company’s senior unsecured revolving credit facility, which provides for $700.0 million of revolving loans, had borrowings outstanding of $527.0 million , which excluded $2.0 million of unamortized debt issuance costs and letters of credit. As of January 3, 2016 , the Company's senior unsecured revolving credit facility had $482.0 million of borrowings outstanding, which excluded $2.4 million of unamortized debt issuance costs and letters of credit. The interest rate on the Company’s senior unsecured revolving credit facility is reset at least monthly to correspond to variable rates that reflect currently available terms and conditions for similar debt. The Company had no change in credit standing during the first six months of fiscal year 2016 . Consequently, the borrowing value of the current year and prior year credit facilities approximate fair value and would be classified as Level 2. The Company's 2021 Notes, with a face value of $500.0 million , had an aggregate carrying value of $495.4 million , net of $1.9 million of unamortized original issue discount and $2.7 million of unamortized debt issuance costs as of July 3, 2016 . The 2021 Notes had an aggregate carrying value of $495.1 million , net of $2.0 million of unamortized original issue discount and $2.9 million of unamortized debt issuance costs as of January 3, 2016 . The 2021 Notes had a fair value of $552.2 million and $518.9 million as of July 3, 2016 and January 3, 2016 , respectively. The fair value of the 2021 Notes is estimated using market quotes from brokers and is based on current rates offered for similar debt. The Company's financing lease obligations had an aggregate carrying value of $37.6 million and $38.2 million as of July 3, 2016 and January 3, 2016 , respectively. The carrying values of the Company's financing lease obligations approximated their fair value as there has been minimal change in the Company's incremental borrowing rate. As of July 3, 2016 , the 2021 Notes and financing lease obligations were classified as Level 2. As of July 3, 2016 , there has not been any significant impact to the fair value of the Company’s derivative liabilities due to credit risk. Similarly, there has not been any significant adverse impact to the Company’s derivative assets based on the evaluation of its counterparties’ credit risks.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies The Company is conducting a number of environmental investigations and remedial actions at current and former locations of the Company and, along with other companies, has been named a potentially responsible party (“PRP”) for certain waste disposal sites. The Company accrues for environmental issues in the accounting period that the Company’s responsibility is established and when the cost can be reasonably estimated. The Company has accrued $11.5 million and $11.8 million as of July 3, 2016 and January 3, 2016 , respectively, which represents its management’s estimate of the cost of the remediation of known environmental matters, and does not include any potential liability for related personal injury or property damage claims. These amounts were included in accrued expenses and other current liabilities. The Company's environmental accrual is not discounted and does not reflect the recovery of any material amounts through insurance or indemnification arrangements. The cost estimates are subject to a number of variables, including the stage of the environmental investigations, the magnitude of the possible contamination, the nature of the potential remedies, possible joint and several liability, the time period over which remediation may occur, and the possible effects of changing laws and regulations. For sites where the Company has been named a PRP, management does not currently anticipate any additional liability to result from the inability of other significant named parties to contribute. The Company expects that the majority of such accrued amounts could be paid out over a period of up to ten years. As assessment and remediation activities progress at each individual site, these liabilities are reviewed and adjusted to reflect additional information as it becomes available. There have been no environmental problems to date that have had, or are expected to have, a material adverse effect on the Company’s condensed consolidated financial statements. While it is possible that a loss exceeding the amounts recorded in the condensed consolidated financial statements may be incurred, the potential exposure is not expected to be materially different from those amounts recorded. The Company is subject to various claims, legal proceedings and investigations covering a wide range of matters that arise in the ordinary course of its business activities. Although the Company has established accruals for potential losses that it believes are probable and reasonably estimable, in the opinion of the Company’s management, based on its review of the information available at this time, the total cost of resolving these contingencies at July 3, 2016 would not have a material adverse effect on the Company’s condensed consolidated financial statements.

Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Adopted and Issued Accounting Pronouncements: From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (the "FASB") and are adopted by the Company as of the specified effective dates. Unless otherwise discussed, such pronouncements did not have or will not have a significant impact on the Company’s condensed consolidated financial position, results of operations and cash flows or do not apply to the Company’s operations. In March 2016, the FASB issued Accounting Standards Update No. 2016-09, Compensation—Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting ("ASU No. 2016-09"). The new standard simplifies the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory withholding requirements, as well as the related classification in the statement of cash flows. The new standard is effective for annual reporting periods beginning after December 15, 2016, and interim periods within those years, with early adoption permitted. The standard requires an entity to recognize all excess tax benefits and tax deficiencies as income tax benefit or expense in the income statement as discrete items in the reporting period in which they occur, and such tax benefits and tax deficiencies are not included in the estimate of an entity’s annual effective tax rate, applied on a prospective basis. Further, the standard eliminates the requirement to defer the recognition of excess tax benefits until the benefit is realized through a reduction to taxes payable. All excess tax benefits previously unrecognized, along with any valuation allowance, should be recognized on a modified retrospective basis as a cumulative adjustment to retained earnings as of the date of adoption. Under ASU No. 2016-09, an entity that applies the treasury stock method in calculating diluted earnings per share is required to exclude excess tax benefits and deficiencies from the calculation of assumed proceeds since such amounts are recognized in the income statement. Excess tax benefits should also be classified as operating activities in the same manner as other cash flows related to income taxes on the statement of cash flows, as such excess tax benefits no longer represent financing activities since they are recognized in the income statement, and should be applied prospectively or retrospectively to all periods presented. The Company adopted ASU No. 2016-09 at the beginning of the first quarter of fiscal year 2016. The Company recorded a cumulative increase of $14.2 million in the beginning of the first quarter of fiscal year 2016 retained earnings with a corresponding increase in deferred tax assets related to the prior years' unrecognized excess tax benefits. Excess tax benefits related to exercised options and vested restricted stock and restricted stock units during the six months ended July 3, 2016 have been recognized in the current period’s income statement. The Company also excluded the excess tax benefits from the calculation of diluted earnings per share for the three and six months ended July 3, 2016 . The Company applied the cash flow presentation section of the guidance on a prospective basis, and the prior period statement of cash flows was not adjusted. ASU No. 2016-09 also allows an entity to elect as an accounting policy either to continue to estimate the total number of awards for which the requisite service period will not be rendered or to account for forfeitures for service based awards as they occur. An entity that elects to account for forfeitures as they occur should apply the accounting change on a modified retrospective basis as a cumulative effect adjustment to retained earnings as of the date of adoption. The Company has elected to account for forfeitures as they occur. The adoption of this accounting policy did not have a material impact on the Company’s consolidated financial position, results of operations and cash flows. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases . The new guidance requires lessees to recognize a lease liability and right-of-use asset on the balance sheet for financing and operating leases. The provisions of this guidance are to be applied using a modified retrospective approach and are effective for annual reporting periods beginning after December 15, 2018, and interim periods within those years, with early adoption permitted. The Company is evaluating the requirements of this guidance and has not yet determined the impact of its adoption on the Company's consolidated financial position, results of operations and cash flows. In July 2015, the FASB issued Accounting Standards Update No. 2015-11, Simplifying the Measurement of Inventory . Under this new guidance, companies that use inventory measurement methods other than last-in, first-out or the retail inventory method should measure inventory at the lower of cost and net realizable value. The provisions of this guidance are to be applied prospectively and are effective for interim and annual reporting periods beginning after December 15, 2016, with early adoption permitted. The Company is evaluating the requirements of this guidance. The adoption is not expected to have a material impact on the Company’s consolidated financial position, results of operations and cash flows. In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). Under this new guidance, an entity should use a five-step process to recognize revenue, depicting the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard also requires new disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Subsequent to the issuance of the standard, the FASB decided to defer the effective date for one year to annual reporting periods beginning after December 15, 2017, with early adoption permitted for annual reporting periods beginning after December 15, 2016. In May 2016, the FASB also issued Accounting Standards Update No. 2016-12, Revenue from Contracts with Customers (Topic 606), Narrow-Scope Improvements and Practical Expedients ("ASU 2016-12") , which amended its revenue recognition guidance in ASU 2014-09 on transition, collectibility, non-cash consideration and the presentation of sales and other similar taxes. In April 2016, the FASB also issued Accounting Standards Update No. 2016-10, Revenue from Contracts with Customers (Topic 606), Identifying Performance Obligations and Licensing ("ASU 2016-10") , which amended its revenue recognition guidance in ASU 2014-09 on identifying performance obligations to allow entities to disregard items that are immaterial in the context of the contract, clarify when a promised good or service is separately identifiable (i.e., distinct within the context of the contract) and allow an entity to elect to account for the cost of shipping and handling performed after control of a good has been transferred to the customer as a fulfillment cost (i.e., an expense). ASU 2016-10 also clarifies how an entity should evaluate the nature of its promise in granting a license of intellectual property ("IP") and requires entities to classify IP in one of two categories: functional IP or symbolic IP, which will determine whether it recognizes revenue over time or at a point in time. ASU 2016-10 also address how entities should consider license renewals and restrictions and apply the exception for sales- and usage-based royalties received in exchange for licenses of IP. ASU 2016-12, ASU 2016-10 and ASU 2014-09 may be adopted either using a full retrospective approach or a modified retrospective approach. The Company is evaluating the requirements of the foregoing standards and has not yet determined the transition method to use or the impact of their adoption on the Company’s consolidated financial position, results of operations and cash flows. The Company does not intend to early adopt these standards.
