Accounting Policies [Abstract]
Nature of Business and Significant Accounting Policies	Basis of Presentation The accompanying consolidated financial statements of FLIR Systems, Inc. and its consolidated subsidiaries (the “Company”) are unaudited and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. In the opinion of management, these statements have been prepared on the same basis as the audited consolidated financial statements and include all adjustments, consisting of only normal recurring adjustments, necessary for a fair presentation of the Company’s consolidated financial position and results of operations for the interim periods. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations. These consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018 . The accompanying consolidated financial statements include the accounts of FLIR Systems, Inc. and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. The results of operations for the interim periods presented are not necessarily indicative of the operating results to be expected for any subsequent interim period or for the year ending December 31, 2019 . Recently Adopted Accounting Pronouncements Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") No. 2016-02, "Leases ("ASC 842"). Effective January 1, 2019, the Company adopted ASC 842 and all the related amendments using the modified retrospective method, using the permitted practical expedients, to those contracts still outstanding as of January 1, 2019. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. The most significant impact was the recognition, on a discounted basis, of right-of-use (ROU) assets totaling approximately $31.9 million and lease liabilities totaling approximately $34.2 million under non-cancelable operating leases as of January 1, 2019 and the related new required disclosures. The standard did not have an impact on the Company's consolidated income statements or consolidated statements of cash flows. For additional disclosures required under the new standard, see Note 9 , " Leases " of the Notes to the Consolidated Financial Statements. FASB ASU No. 2017-04, "Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment" ("ASU 2017-04"). Effective January 1, 2019, the Company adopted ASU 2017-04. The amendments in this update simplify the subsequent measurement of goodwill by removing the second step of the two-step impairment test. The amendment also requires an entity to perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The standard did not have an impact on the Company's consolidated financial statements. FASB ASU No. 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income" ("ASU 2018-02"). Effective January 1, 2019, the Company adopted ASU 2018-02. The standard allows companies to reclassify stranded tax effects in Accumulated other comprehensive earnings (loss) that have been caused by the Tax Cuts and Jobs Act of 2017 (the Act) to Retained earnings for each period in which the effect of the change in the U.S. federal corporate income tax rate is recorded . However, the FASB made the reclassification optional. As a result, the Company assessed the impact of the ASU on its financial statements and did not exercise the option to reclassify the stranded tax effects caused by the Act. FASB ASU No. 2018-07, "Improvements to Nonemployee Share-Based Payment Accounting" ("ASU 2018-07"). Effective January 1, 2019, the Company adopted ASU 2018-07. The standard more closely aligns the accounting for employee and nonemployee share-based payments. The standard did not have a material impact on the Company's consolidated financial statements or disclosures. Note 1.

Revenue Revenue

Revenue Revenue	6 Months Ended
	Jun. 30, 2019
Revenue from Contract with Customer [Abstract]
Revenue	Revenue Revenue Recognition The Company designs, markets and sells products primarily as commercial, off-the-shelf products. Certain customers request different system configurations, based on standard options or accessories that the Company offers. Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company regularly enters into contracts that can include various combinations of products and services, which are generally capable of being distinct and accounted for as separate performance obligations. In such situations, contract values are allocated to each performance obligation based on its relative estimated standalone selling price. The vast majority of the Company's revenues are recognized at a point in time when goods are transferred to a customer. However, for certain contracts that include highly customized components, if performance does not create an asset with an alternative use and termination for convenience clauses provide an enforceable right to payment for performance completed to date, revenue is recognized over time as the performance obligation is satisfied. Revenue includes certain shipping and handling costs and is stated net of third party agency fees. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of goods sold. Revenue is recognized net of allowances for returns and net of taxes collected from customers which are subsequently remitted to governmental authorities. The Company's products are sold with warranty provisions that require it to remedy deficiencies in quality or performance of the Company's products over a specified period of time, generally twelve to twenty-four months, at no cost to its customers. Warranty liabilities are established at the time that revenue is recognized at levels that represent the Company's estimate of the costs that will be incurred to fulfill those warranty requirements. Provisions for estimated losses on sales or related receivables are recorded when identified. Service revenue is deferred and recognized over the contract period, as is the case for extended warranty contracts, or recognized as services are provided. See Note 19 , " Operating Segments and Related Information - Revenue and Long-Lived Assets by Geographic Area " for information related to the Company’s revenues disaggregated by significant geographical region and operating segment. Contract Balances The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables and deferred revenue and advance payments from customers on the Consolidated Balance Sheets. Contract assets and liabilities are reported on a contract-by-contract basis. The Company had no material deferred contract costs recorded on the Consolidated Balance Sheet as of June 30, 2019 . Contract assets : The Company recognizes unbilled receivables as contract assets when the Company has rights to consideration for work completed but has not yet billed at the reporting date. Unbilled receivables are included within accounts receivable, net on the Consolidated Balance Sheets. The balance of unbilled receivables as of June 30, 2019 and December 31, 2018 were $12.3 million and $10.5 million , respectively. Note 2. Revenue - (Continued) Contract Balances Contract Liabilities : The Company records contract liabilities when cash payments are received or due in advance of the Company's performance. Contract liabilities include deferred revenue and advance payments from customers. Contract liabilities are classified as either current or long-term in the Consolidated Balance Sheets based on the timing of when the Company expects to recognize revenue. As of June 30, 2019 and December 31, 2018 , contract liability balances totaled $73.5 million and $66.4 million , respectively. These balances included amounts classified as long-term as of June 30, 2019 and December 31, 2018 and were $13.5 million and $14.0 million , respectively, and are included within pension and other long-term liabilities in the accompanying Consolidated Balance Sheets. Approximately $35.9 million of revenue recognized during the six month period ended June 30, 2019 was included in the combined opening contract liability balances. Remaining Performance Obligations Remaining performance obligations represent the aggregate transaction price allocated to performance obligations with an original contract term greater than one year which are fully or partially unsatisfied at the end of the period. While the remaining performance obligation disclosure is similar in concept to backlog, the definition of remaining performance obligations excludes contracts that provide the customer with the right to cancel or terminate for convenience with no substantial penalty, even if historical experience indicates the likelihood of cancellation or termination is remote. The Company has elected to exclude contracts with customers with an original term of one year or less from remaining performance obligations while these contracts are included within backlog. As of June 30, 2019 , the aggregate amount of the transaction price allocated to remaining performance obligations was approximately $144.8 million . The Company expects to recognize revenue on approximately 72 percent of the remaining performance obligations over the next twelve months, and the remainder recognized thereafter.

Share-based Compensation [Abstract]
Stock-based Compensation	Stock-based Compensation Stock Incentive Plans The Company has a stock-based compensation program that provides equity incentives for employees, consultants and directors. This program includes incentive and non-statutory stock options and non-vested stock awards (referred to as restricted stock unit awards) granted under two plans: the FLIR Systems, Inc. 2002 Stock Incentive Plan (the “2002 Plan”) and the FLIR Systems, Inc. 2011 Stock Incentive Plan (the “2011 Plan”). The Company has discontinued issuing awards out of the 2002 Plan but previously-granted awards under the 2002 Plan remain outstanding. The Company has granted time-based options, time-based restricted stock unit awards, market-based restricted stock unit awards and performance-based restricted stock unit awards. Options generally expire ten years from the grant date. Time-based options and restricted stock unit awards generally vest over a three year period. Market-based restricted stock unit awards were earned based upon the Company's total shareholder return compared to the total shareholder return of the component company at the 60th percentile level in the S&P 500 Index over a three year period. Performance-based restricted stock unit awards granted during the year ended December 31, 2016 were earned based upon the Company's return on invested capital over a three year period. Performance-based restricted stock unit awards granted during the year ended December 31, 2017 may be earned based upon the Company's operating margin performance over a three year period. Performance-based restricted stock unit awards granted during the year ended December 31, 2018 and during the quarter ended June 30, 2019 may be earned based upon a combination of the Company's revenue and operating performance over a three year period. Certain shares vested under the performance-based restricted stock unit awards and the market-based restricted stock unit awards must be held by the participant for a period of one year from the vest date. Employee Stock Purchase Plan The Company has an Employee Stock Purchase Plan (the “ESPP”) which allows employees to purchase shares of the Company’s common stock at 85 percent of the fair market value at the lower of either the date of enrollment or the purchase date. The ESPP provides for six-month offerings commencing on May 1 and November 1 of each year with purchases on April 30 and October 31 of each year. Shares purchased under the 2009 ESPP must be held by employees for a period of at least 18 months after the date of purchase. On April 19, 2019, the Company's shareholders approved the FLIR Systems, Inc. 2019 Employee Stock Purchase Plan ("2019 ESPP"). The final purchase under the 2009 ESPP was on April 30, 2019 and the first offering under the 2019 ESPP commenced on May 1, 2019. Note 3.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments Factors used in determining the fair value of financial assets and liabilities are summarized into three broad categories in accordance with FASB ASC Topic 820, “Fair Value Measurements”: Level 1 – quoted prices in active markets for identical securities as of the reporting date; Level 2 – other significant directly or indirectly observable inputs, including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, and observable market prices for identical instruments that are traded in less active markets; and Level 3 – significant inputs that are generally less observable than objective sources, including our own assumptions in determining fair value. The factors or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The Company had $1.3 million and $200.0 million of cash equivalents at June 30, 2019 and December 31, 2018 , respectively, which were primarily investments in money market funds and overnight deposits. The Company has categorized its cash equivalents as a Level 1 financial asset, measured at fair value based on quoted prices in active markets of identical assets. All cash equivalents are in instruments that are convertible to cash daily. The fair value of the Company’s foreign currency contracts as of June 30, 2019 and December 31, 2018 , and the interest rate swap contract as of June 30, 2019 are disclosed in Note 6 , " Derivative Financial Instruments ," and are based on Level 2 inputs. The fair value of the Company's borrowings under the Credit Agreement as described in Note 13 , " Credit Agreement ," as of June 30, 2019 approximates the carrying value. The fair value of the Company’s senior unsecured notes as described in Note 14 , " Long-Term Debt ," is approximately $430.6 million and $418.8 million based upon Level 2 inputs at June 30, 2019 and December 31, 2018 , respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments Foreign Currency Exchange Rate Risk The Company enters into foreign currency forward contracts not formally designated as hedges to manage the consolidated exchange rate risk associated with the remeasurement of non-functional currency denominated monetary assets and liabilities. Changes in fair value of foreign currency forward contracts are recognized in income at the end of each reporting period based on the difference between the contract rate and the spot rate. In general, these gains and losses are offset in the Consolidated Statements of Income by the reciprocal gains and losses from the underlying assets or liabilities which originally gave rise to the exposure. The net amount of the gains and losses related to derivative instruments recorded in other (income) expense, net for the three and six months ended June 30, 2019 were net losses of $0.6 million and $0.3 million , respectively. The net losses for the three and six month and 2018 were $4.0 million and $8.6 million , respectively. The table below presents the net notional amounts of the Company’s outstanding foreign currency forward contracts by currency (in thousands): June 30, December 31, 2019 2018 European euro $ 71,168 $ 61,452 Canadian dollar 19,441 19,685 British pound sterling 11,570 609 Brazilian real 8,518 8,598 Swedish kronor 5,963 3,608 Norwegian kroner 4,295 — Australian dollar 1,054 1,131 Other 743 813 $ 122,752 $ 95,896 At June 30, 2019 , the Company’s foreign currency forward contracts, in general, had maturities of three months or less. Note 6. Derivative Financial Instruments - (Continued) Foreign Currency Exchange Rate Risk - (Continued) The carrying amounts of the foreign exchange contracts included in the Consolidated Balance Sheets are as follows (in thousands): June 30, 2019 December 31, 2018 Prepaid Expenses and Other Current Assets Other Current Liabilities Prepaid Expenses and Other Current Assets Other Current Liabilities Foreign exchange contracts $ 1,690 $ 647 $ 431 $ 951 Interest Rate Swap Contracts The Company's outstanding debt at June 30, 2019 consists of fixed rate notes and an unsecured credit facility consisting of a revolving loan facility, a U.S. dollar term loan facility and a Swedish kronor term loan facility, all of which accrue interest at a floating rate. As discussed in Note 13 , " Credit Agreement ," interest expense on the Company's floating rate debt is calculated based on a fixed spread over the applicable Eurocurrency rate (e.g. LIBOR). Therefore, fluctuations in market interest rates will cause interest expense increases or decreases on a given amount of floating rate debt. The Company is managing its interest rate risk related to certain floating rate debt through a floored amortizing interest rate swap (“floored swap”) in which the Company receives floating rate payments subject to a floor of zero percent and makes fixed rate payments. The impact of the floored swap is to fix the floating rate basis for the calculation of interest on the unsecured Swedish kronor term loan at the levels indicated in the table below. The effective interest rate paid is equal to the fixed rates shown below plus the applicable spread then in effect. At June 30, 2019 , the effective interest rate on the Swedish kronor term loan which includes the impact of the floored swap was 1.840 percent . As of June 30, 2019 , the following floored swap was outstanding: Effective Date Current Notional Amount (in millions Swedish Kronor) Fixed Rate Maturity Date March 29, 2019 1,372.8 0.59% March 31, 2024 The floored swap is designated and effective as a cash flow hedge with individual swap cash flows recorded as an asset or liability in the Company's Consolidated Balance Sheets at fair value. Fair value adjustments are recorded as an adjustment to accumulated other comprehensive earnings, except that any gains and losses on ineffectiveness of the floored swap would be recorded as an adjustment to other expense (income), net. The net fair value carrying amount of the Company's floored swap was an unrealized loss of $2.1 million , which has been recorded in prepaid expenses and other current assets, other current liabilities and pension and other long-term liabilities in the Consolidated Balance Sheet as of June 30, 2019 . All of the Company's derivative counterparties have investment grade credit ratings. The Company is a party to master netting arrangements that contain features that allow counterparties to net settle amounts arising from multiple separate derivative transactions or net settle in the case of certain triggering events such as a bankruptcy or major default of one of the counterparties to the transaction. The Company has not pledged assets or posted collateral as a requirement for entering into or maintaining derivative positions.

Leases [Abstract]
Leases	Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in other assets, other current liabilities, and pension and other long-term liabilities on the consolidated balance sheets. The Company does not have any finance leases at June 30, 2019 . Operating lease right-of-use assets ("ROU assets") represent the Company’s right to use an underlying asset for the lease term and operating lease liabilities represent the obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the commencement date of the lease based on the present value of minimum fixed lease payments over the lease term. As most of the leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. ROU assets also include prepaid lease payments made prior to commencement of the lease plus initial capitalized direct costs and exclude tenant improvement allowances. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the option will be exercised. Lease expense for minimum fixed lease payments is recognized on a straight-line basis over the lease term. The Company has elected to apply the short-term lease exemption in accordance with guidance, and therefore, short-term leases (leases with a term of twelve months or less) are not recorded on the balance sheet. The Company has only a small number of leases that qualify for the exemption and the amount of its remaining short-term lease commitments is not significant. Most of the Company’s operating leases are for buildings, warehouses and office space. These leases have remaining lease terms of approximately one year to ten years . The components of lease expense was as follows (in thousands): Three Months Ended June 30, 2019 Six Months Ended June 30, 2019 Operating lease expense $ 2,837 $ 5,472 Short-term lease expense 327 573 Variable lease expense 602 1,116 Total lease expense $ 3,766 $ 7,161 Supplemental cash flow information related to operating leases (in thousands): Three Months Ended June 30, 2019 Six Months Ended June 30, 2019 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 2,761 $ 5,183 Right-of-use assets obtained in exchange for lease obligations: Operating leases $ 7,086 $ 7,386 Supplemental balance sheet information related to operating leases (in thousands): June 30, 2019 Operating lease right-of-use assets $ 33,527 Operating lease liabilities $ 37,091 Note 9.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Matters Involving the United States Department of State and Department of Commerce On April 24, 2018, the Company entered into a Consent Agreement with the United States Department of State's Directorate of Defense Trade Controls (“DDTC”) to resolve allegations regarding the unauthorized export of technical data and defense services to dual and third country nationals from certain Company facilities, the failure to properly use and manage export licenses and export authorizations, and failures to report certain payments under 22 CFR Part 130 in potential violation of the International Traffic in Arms Regulation (“ITAR”). The Consent Agreement has a four-year term and provides for: (i) a civil penalty of $30.0 million with $15.0 million of this amount suspended on the condition that the funds have or will be used for Department-approved Consent Agreement remedial compliance measures, (ii) the appointment of an external Special Compliance Official to oversee compliance with the Consent Agreement and the ITAR; (iii) two external audits of the Company’s ITAR compliance program; and (iv) continued implementation of ongoing remedial compliance measures and additional remedial compliance measures related to automated systems and ITAR compliance policies, procedures, and training. During the three-month period ended March 31, 2018, the Company recorded a $15.0 million charge for the portion of the penalty that is not subject to suspension. In April 2018, the Company paid $1.0 million of the $15.0 million charge and as of March 31, 2019, the remaining amount payable of $3.5 million and $10.5 million has been recorded in other current liabilities and pension and other long-term liabilities, respectively. The remaining $14.0 million is payable in annual installments of $3.5 million through April 2022. The Company expects recent and future investments in remedial compliance measures will be sufficient to cover the $15.0 million suspension amount. As part of the Consent Agreement, DDTC acknowledged that the Company voluntarily disclosed certain of the alleged Arms Export Control Act and ITAR violations, which were resolved pursuant to the Consent Agreement, cooperated in the DDTC's review, and instituted a number of compliance program improvements. In May 2017, the Company submitted an initial notification to DDTC regarding potential violations related to certain export classifications obtained through the commodity jurisdiction process and a final voluntary disclosure in August 2017. The Company also submitted a voluntary self-disclosure regarding the same matter with the United States Department of Commerce Bureau of Industry and Security ("BIS"). DDTC and BIS both acknowledged the submissions and, at the request of the agencies, the Company executed tolling agreements for this matter. The DDTC tolling agreement has lapsed; the Company executed a tolling agreement with BIS, suspending the statute of limitations through November 1, 2019. The Company also executed a tolling agreement with the Department of Justice ("DOJ"), suspending the statute of limitations with the DOJ through December 1, 2019. This matter remains under review by DDTC, DOJ, and BIS. In June 2017, BIS informed the Company of additional export licensing requirements that restrict the Company’s ability to sell certain thermal products without a license to customers in China not identified on a list maintained by the United States Department of Commerce. This action was precipitated by concerns of sale without a license or potential diversion of some of the Company's products to prohibited end users and to countries subject to economic and other sanctions implemented by the United States. BIS subsequently favorably modified these restrictions to reduce the applicability of the restrictions to sales of FLIR's Tau camera cores (as opposed to finished products containing Tau camera cores) to customers in China not identified on a list maintained by the United States Department of Commerce and persons in a country other than those in EAR Country Group A:5 (Supplement No. 1 to Part 740 of the EAR). If the Company is found to have violated applicable rules and regulations with respect to customers and limitations on the export and end use of the Company’s products, the Company could be subject to substantial fines and penalties, suspension of existing licenses or other authorizations and/or loss or suspension of export privileges. The Company is unable to reasonably estimate the time it may take to resolve these matters or the amount or range of potential loss, penalty or other government action, if any, that may be incurred in connection with these matters. However, an unfavorable outcome could result in substantial fines and penalties or loss or suspension of export privileges or of particular authorizations that could be material to the Company’s financial position, results of operations or cash flows in and following the period in which such an outcome becomes estimable or known. Note 17. Contingencies - (Continued) SkyWatch Product Quality Matters In March 2016, the Company learned of potential quality concerns with respect to as many as 315 Level III and Level IV SkyWatch Surveillance Towers sold by FLIR and companies acquired by FLIR from 2002 through 2014. The Company notified customers who purchased the affected SkyWatch Towers of the potential concerns and, as a precautionary measure, also temporarily suspended production of all Level III and Level IV SkyWatch Towers pending the completion of its review and the implementation of any necessary remedial measures. The Company identified the cause of these quality issues, notified customers of their option to request repair and modification of their in-field units, and has begun in-field repairs of identified affected units. While there still remains uncertainty related to estimating the costs associated with a potential remedy and number of units which may require such remedy, the Company currently estimates the range of potential loss on remaining units to be between $5.1 million and $11.7 million . As no single amount within the range is a better estimate than any other amount within the range, the Company has recorded an accrual of $5.1 million in other current liabilities as of June 30, 2019. Factors underlying this estimated range of loss may change from time to time, and actual results may vary significantly from this estimate. Shareholder Derivative Lawsuit In October 2018, a shareholder filed a derivative lawsuit in the Circuit Court of the State of Oregon for the County of Multnomah under the caption Stein v. Carter, et al., Case No. 18CV46824, against the Company, as a nominal defendant, and certain current and former directors of the Company. Pointing to the Company’s 2015 settlement with the United States Securities and Exchange Commission of alleged United States Foreign Corrupt Practices Act violations and 2018 settlement with United States Department of State of alleged export control violations, the complaint alleges that the Company’s directors breached their fiduciary duties by failing to ensure that the Company had internal controls in place that would have prevented the alleged underlying misconduct and these settlements. The complaint also asserts claims for corporate waste and unjust enrichment, and seeks unspecified monetary damages from the individual defendants, injunctive relief, disgorgement of director compensation, and attorneys’ fees and costs. Because the complaint is derivative in nature, it does not seek monetary damages from the Company. However, the Company may be required to advance, and ultimately be responsible for, the legal fees and costs incurred by the individual defendants. On January 16, 2019, the defendants moved to dismiss the complaint. On March 21, 2019, instead of opposing the defendants' motion, the plaintiff filed an amended complaint. On April 25, 2019, the defendants moved to dismiss the amended complaint. On July 22, 2019, after complete briefing and oral argument, the court granted the defendants’ motion to dismiss the amended complaint without prejudice and with leave to amend. On July 29, 2019, the plaintiff informed the court that the plaintiff would not file a second amended complaint. The court has indicated that it will enter an order of judgment and dismissal without prejudice which is expected in the third quarter of 2019. Other Matters The Company is also subject to other legal and administrative proceedings, investigations, claims and litigation arising in the ordinary course of business not specifically identified above. In these identified matters and others not specifically identified, the Company records a liability with respect to a matter when management believes it is both probable that a liability has been incurred and the Company can reasonably estimate the amount of the loss. The Company believes it has recorded adequate provisions for any probable and estimable losses for matters in existence on the date hereof. The Company reviews these provisions to reflect the impact of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular matter. While the outcome of each of these matters is currently not determinable, the Company does not expect that the ultimate resolution of any such matter will individually have a material adverse effect on the Company’s financial position, results of operations or cash flows. The costs to resolve all such matters may in the aggregate have a material adverse effect on the Company’s financial position, results of operations or cash flows.

Income Tax Disclosure [Text Block]	Income Taxes The provision for income taxes was as follows: Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 Income tax provision $ 12,005 $ 11,390 $ 25,014 $ 26,810 Effective tax rate 20.7 % 13.7 % 18.8 % 19.5 % The effective tax rate for the three and six months ended June 30, 2019 , is lower than the United States Federal tax rate of 21.0 percent mainly due to a reduction in previously non-deductible interest expense and excess tax benefits from stock compensation, offset partially by state taxes, higher tax rates applied to income earned in certain foreign jurisdictions, and other discrete items. As of June 30, 2019 and December 31, 2018, the Company has accrued income tax liabilities of $42.9 million related to the transition tax enacted on December 22, 2017 as part of the Tax Cuts and Jobs Act. Of the amounts accrued, none are expected to be due within one year. The remaining transition tax will not accrue interest and will be paid in annual installments beginning in 2020 through 2024. As of June 30, 2019 , the Company had approximately $21.1 million of unrecognized tax benefits, all of which would affect the Company’s effective tax rate if recognized. The Company anticipates approximately $5.2 million of its net unrecognized tax benefits will be recognized within 12 months as the result of settlements or effective settlements with various tax authorities, the closure of certain audits and the lapse of the applicable statute of limitations. The Company classifies interest and penalties related to unrecognized tax benefits in the income tax provision. As of June 30, 2019 , the Company had $6.6 million of accrued interest and penalties related to unrecognized tax benefits that are recorded as current and non-current accrued income taxes on the Consolidated Balance Sheet. During the three-month period ending December 31, 2018, the Swedish Tax Authority (“STA”) issued a reassessment of tax for the year ending December 31, 2012 to one of the Company's non-operating subsidiaries in Sweden. The reassessment concerns the use of tax credits applied against capital gains pursuant to European Union Council Directive 2009/133/EC, commonly referred to as the EU Merger Directive, and assesses taxes and penalties totaling approximately $323.4 million (Swedish kronor 3.0 billion). The Company believes the STA’s assertions in the reassessment are not in accordance with Swedish tax regulations and plans to defend the Company's positions with the STA and through the Swedish court system, as necessary. Consequently, no adjustment to the Company's unrecognized tax benefits has been recorded in relation to this matter. Management believes that the Company's recorded tax liabilities are adequate in the aggregate for its income tax exposures. The Company currently has the following tax years open to examination by major taxing jurisdictions: Tax Years: United States Federal 2015 - 2017 State of California 2014 - 2017 State of Massachusetts 2014 - 2017 State of Oregon 2015 - 2017 Sweden 2012 - 2017 United Kingdom 2014 - 2017 Belgium 2011 - 2017

Accounting Policies [Abstract]
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") No. 2016-02, "Leases ("ASC 842"). Effective January 1, 2019, the Company adopted ASC 842 and all the related amendments using the modified retrospective method, using the permitted practical expedients, to those contracts still outstanding as of January 1, 2019. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. The most significant impact was the recognition, on a discounted basis, of right-of-use (ROU) assets totaling approximately $31.9 million and lease liabilities totaling approximately $34.2 million under non-cancelable operating leases as of January 1, 2019 and the related new required disclosures. The standard did not have an impact on the Company's consolidated income statements or consolidated statements of cash flows. For additional disclosures required under the new standard, see Note 9 , " Leases " of the Notes to the Consolidated Financial Statements. FASB ASU No. 2017-04, "Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment" ("ASU 2017-04"). Effective January 1, 2019, the Company adopted ASU 2017-04. The amendments in this update simplify the subsequent measurement of goodwill by removing the second step of the two-step impairment test. The amendment also requires an entity to perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The standard did not have an impact on the Company's consolidated financial statements. FASB ASU No. 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income" ("ASU 2018-02"). Effective January 1, 2019, the Company adopted ASU 2018-02. The standard allows companies to reclassify stranded tax effects in Accumulated other comprehensive earnings (loss) that have been caused by the Tax Cuts and Jobs Act of 2017 (the Act) to Retained earnings for each period in which the effect of the change in the U.S. federal corporate income tax rate is recorded . However, the FASB made the reclassification optional. As a result, the Company assessed the impact of the ASU on its financial statements and did not exercise the option to reclassify the stranded tax effects caused by the Act. FASB ASU No. 2018-07, "Improvements to Nonemployee Share-Based Payment Accounting" ("ASU 2018-07"). Effective January 1, 2019, the Company adopted ASU 2018-07. The standard more closely aligns the accounting for employee and nonemployee share-based payments. The standard did not have a material impact on the Company's consolidated financial statements or disclosures. Note 1. Basis of Presentation - (Continued) Recently Adopted Accounting Pronouncements - (Continued) FASB ASU No. 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract” (“ASU 2018-15”). Effective January 1, 2019, the Company adopted ASU 2018-15. The amendments in this update align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments in this update. The standard did not have a material impact on the Company’s consolidated financial statements.
