Accounting Policies [Abstract]
Significant Accounting Policies	Note 1 —Summary of Significant Accounting Policies (a) Business Benchmark Electronics, Inc. (the Company) is a Texas corporation that provides innovative product design, engineering services, technology solutions and advanced manufacturing services. From initial product concept to volume production, including direct order fulfillment and aftermarket services, the Company has been providi ng integrated services and solutions to original equipment manufacturers (OEMs) since 1979. The Company serves the following industries: aerospace and defense (A&D), medical technologies, complex industrials, test and instrumentation, next-generation telec ommunications and high-end computing. The Company has manufacturing operations located in the United States and Mexico (the Americas), Asia and Europe . (b) Principles of Consolidation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) and include the financial statements of Benchmark Electronics, Inc. and its wholly owned and majority owned subsidiaries. All significant interc ompany balances and transactions have been eliminated in consolidation. Effective January 1, 2018, the Company adopted the requirements of a new a c counting standard related to revenue recognition as discussed in Note 1 (q) . All amounts and disclosures set forth in this Form 10-K have been updated to comply with the new standard, as indicated by the “as adjusted” column heading. (c) Cash and Cash Equivalents The Company considers all highly liquid debt instruments with an original maturity at the date of purchase of three months or less to be cash equivalents. Cash equivalents of $ 265.4 million and $ 581.4 million at December 31, 2018 and 2017 , respectively, consist ed primarily of money-market funds and time deposits with an initial term of less than three months. (d) Allowance for Doubtful Accounts Accounts receivable are recorded net of allowances for amounts not expected to be collected. In estimating the allowance, management considers a specific customer’s financial condition, payment history, and various information or disclosures by the customer or other publicly available information. Acco unts receivable are charged against the allowance after all reasonable efforts to collect the full amount (including litigation, where appropriate) have bee n exhausted. During both the third quarter of 2018 and the first quarter of 2017 , the Company recorded $ 1 .7 million in charge s for a provision to accounts receivable associated with the insolvency of two customer s . (e ) Inventories Inventories include material, labor and overhead and are stated at the lower of cost (principally first -in, first-out method) or net realizable value . (f ) Property, Plant and Equipment Property, plant and equipment are stated at cost. Depreciation is calculated on the straight-line method over the useful lives of the assets – 5 to 40 years for buildings an d building improvements, 2 to 15 years for machinery and equipment, 2 to 12 years for furniture and fixtures and 2 to 8 years for vehicles. Leasehol d improvements are amortized on the straight-line method over the shorter of the useful life of the improvement or the remainder of the lease term. (g ) Goodwill and Other Intangible Assets Goodwill represents the excess of purchase price over fair value of net assets acquired. Goodwill and intangible assets acquired in a business combination and determined to have an indefinite useful life are not amortized, but instead assessed for impairment at least annually. Intangible assets , including those acquired in a business combination, with estimable useful liv es are amortized over their respective estimated useful lives to their estimated residual values. (h ) Impairment of Long-Lived Assets and Goodwill Long-lived assets, such as property, plant, and equipment, and purchased intangibles subject to amortizatio n, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is evaluated by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated undiscounted future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the a sset exceeds the estimated fair value of the asset. Assets to be disposed of would be separately disclosed and reported at the lower of the carrying amount or estimated fair value less costs to sell, and are no longer depreciated. The assets and liabilitie s of a disposed group classified as held for sale would be disclosed separately in the appropriate asset and liability sections of the consolidated balance sheet. Goodwill is tested for impairment on an annual basis, during the fourth quarter , and whenever events and changes in circumstances suggest that the carrying amount may be impaired. Circumstances that may lead to the impairment of goodwill include unforeseen decreases in future performance or industry demand or the restructuring of our operations as a result of a change in our business strategy. A qualitative assessment is allowed to determine if goodwill is potentially impaired. Based on this qualitative assessment, if the Company determines that it is more likely than not that the reporting unit’s fair value i s less than its carrying value, then it performs a two-step goodwill impairment test, otherwise no further analysis is required. In connection with its annual qualitative goodwill impairment assessments as of December 31, 2018 , 2017 and 2016 , the Company con cluded that goodwill was not impaired. (i ) Earnings (Loss) Per Share Basic earnings per share is computed using the weighted-average number of shares outstanding. Diluted earnings per share is computed using the weighted-average number of shares outstanding adjusted for the incremental shares attributed to outstanding stock equivalents. Stock equivalents include common shares issuable upon the exercise of stock options and other equity instruments, and are computed using the treasury stock method. Under the treasury stock method, the exercise price of a share, the amount of compensation cost, if any, for future service that the Company has not yet recognized are assumed to be used to rep urchase shares in the current period. The following table sets forth the calculation of basic and diluted earnings (loss) per share. Year Ended December 31, (in thousands, except per share data) 2018 2017 2016 (as adjusted) Net income (loss) $ 22,817 $ (31,901) $ 63,933 Denominator for basic earnings per share – weighted-average number of common shares outstanding during the period 46,332 49,680 49,298 Incremental common shares attributable to exercise of dilutive options 104 — 313 Incremental common shares attributable to outstanding restricted stock units 219 — 214 Denominator for diluted earnings per share 46,655 49,680 49,825 Basic earnings (loss) per share $ 0.49 $ (0.64) $ 1.30 Diluted earnings (loss) per share $ 0.49 $ (0.64) $ 1.28 Potentially dilutive securities totaling 0.6 million common shares in 2017 were not included in the computation of diluted loss per share because their effect would have decreased the loss per share. Options to purchase 0.4 mi llion common shares in 2016 were not included in the computation of diluted earnings per share because their effect would have been anti-dilutive. (j ) Revenue Recognition T he Company recognizes revenue as the customer takes control of the manufacture d products built to customer specifications. Under the majority of the Company’s manufacturing contracts with customers, the customer controls all of the work-in-progress as products are being built. Revenues under these con tracts are recognized over time based on the cost-to-cost method. Under other manufacturing contracts, the customer does not take control of the product until it is completed. Under these contracts, the Company continues to recognize revenue upon transfer of control of product to the cus tomer , which is generally when the goods are shipped . Revenue from design, development and engineering services also continues to be recognized over time as the services are performed . The Company’s performance obligations generally have an expected duration of one year or less. The Company applies the practical expedients and does not disclose information about remaining performance obligations that have original expected durations of one year or less or any significant financing components in the co ntracts. The Company recognizes the incremental costs, if any, of obtaining contracts as an expense when incurred since the amortization period of the assets that the Company otherwise would have recognized is one year less. ( k ) Income Taxes Income taxe s are accounted for under the asset and liability method. Deferred income taxes are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respect ive tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. The Company records a valuation allowance to reduce its deferred tax assets to the amounts that are more likely than not to be realized. The Company has considered the sch eduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in assessing the need for the valuation allowance. (l ) Stock-Based Compensation All share-based payments to employees, including grants of employee stock options (which have not been awarded since 2015) , are recognized in the financial statements based on their grant date fair values. The total compensation cost recognized for stock-based awards was $10.1 million, $7.8 million and $5.3 million for 2018 , 2017 and 2016 , respectively. The total income tax benefit recognized in the income statement for stock-based awards was $2.4 million, $2.8 million and $1.1 million for 2018 , 2017 and 2016 , respecti vely. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. Awards of restricted stock units and performance-based restricted stock units are valued at the closing market price of the Company’s common stock on the date of grant. For performance-based restricted stock units, compensation expense is based on the probability that the performance goals will be achieved, which is monitored by management throughout the requisite service period. When it becomes probable, based on the Company’s expectation of performance during the measurement period, that more or less than the previous estimate of the awarded shares will vest, an adjustment to stock-based compensation expense is recognized as a change in accounting estimate . As of December 31, 2018 , the unrecognized compensation cost and remaining weighted-average amortization related to stock-based awards were as follows: Performance- based Restricted Restricted Stock Stock Stock (in thousands) Options Units Units (1) Unrecognized compensation cost $ 44 $ 12,738 $ 2,461 Remaining weighted-average amortization period 0.2 years 2.4 years 1.2 years (1) Based on the probable achievement of the performance goals identified in each award. The total cash received as a result of stock option exercises in 2018 , 2017 and 2016 was approximately $3.6 million, $11.2 million and $18.8 million, respectively. The actual tax benefit realized as a result of stock option exercises and the vesting of other share-based awards during 2018 , 2017 and 2016 was $2.5 million, $5.0 million and $3.7 million, respectively. For 2018 , 2017 and 2016 , the total intrinsic value of stock options exercised was $2.3 million, $7.7 million and $5.1 million, respectively. The Company awarded performance-based restricted stock units to employees during 2018 , 2017 and 2016 . The number of performance-based restric ted stock units that will ultimately be earned will not be determined until the end of the corresponding performance periods, and may vary from as low as zero to as high as 2.5 times the target number depending on the level of achievement of certain perfor mance goals. The level of achievement of these goals is based upon the financial results of the Company for the last full calendar year within the performance period. The performance goals consist of certain levels of achievement using the following financ ial metrics: revenue growth, operating margin expansion, and return on invested capital. If the performance goals are not met based on the Company’s financial results, the applicable performance-based restricted stock units will not vest and will be forfei ted. Shares subject to forfeited performance-based restricted stock units will be available for issuance under the Company’s 2010 Omnibus Incentive Compensation Plan (the 2010 Plan). (m ) Use of Estimates Management of the Company has made a number of est imates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities to prepare these financial statements in accordance with U.S. GAAP. On an ongoing basis, management evaluates these estimates , including those related to accounts receivable, inventories, income taxes, long-lived assets, stock-based compensation a nd contingencies and litigation . Actual results could differ from those estimates. (n ) Fair Values of Financial Instruments Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A three-tier fair value hierarchy of inputs is employed to determine fair value measurements. Level 1 inputs are quoted prices (unadjusted) in active markets for id entical assets and liabilities. Level 2 inputs are observable prices that are not quoted on active exchanges, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; and model-derived valuations whose inputs are observable or whose significan t value drivers are observable. Level 3 inputs are unobservable inputs employed for measuring the fair value of assets or liabilities. This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. T he Company’s f inancial instruments include cash equivalents, accounts and other receivables, accoun ts payable, accrued liabilities and long-term debt and capital lease obligations. The Company believes that the carrying values of these instruments approxim ate their fair value. As of December 31, 2018 , all of the Company’s long-term investments and derivative instruments were recorded at f air value using Level 3 inputs. See Note 12 . (o ) Foreign Currency For foreign subsidiaries using the local currency as their functional currency, assets and liabilities are translated at exchange rates in effect at the balance sheet date and income and expenses are translated at average exchange rates. The effects of these translation adjustments are reported i n other comprehensive income. Exchange losses arising from transactions denominated in a currency other than the functional currency of the entity involved are included in other expense and totaled approximately $ 1.0 million, $ 2.1 million and $ 0.5 million in 2018 , 2017 and 2016 , respectively . These amounts include the amount of gain (loss) recognized in income due to forward currency exchange contract s. (p ) Derivative Instruments All derivative instruments are recorded on the balance sheet at fa ir value. The Company uses derivative instruments to manage the variability of foreign currency obligations and interest rates . The Company does not enter into derivative arrangements for speculative purposes . Generally, if a derivative instrument is desig nated as a cash flow hedge, the change in the fair value of the derivative is recorded in other comprehensive income to the extent the derivative is effective, and recognized in the consolidated statement of i ncome when the hedged item affects earnings. Ch anges in fair value of derivatives that are not designated as hedges are recorded in earnings. Cash receipts and cash payments related to derivative instruments are recorded in the same category as the cash flows from the items being hedged on the c onsolid ated s tatements of c ash f lows. (q) New Accounting Pronouncements Adopted in 2018 In May 2017, the Financial Accounting Standards Board (FASB) issued a new accounting standards update that provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The Company adopted the new guidance effective January 1, 2018. The impact of adoption on the Company's consolidated financial statements is dependent on future c hanges to stock-based compensation awards . In August 2016, the FASB issued a new accounting standards update, which seeks to reduce the existing diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The Company adopted this new update effective January 1, 2018. The adoption of this guidance had no impact on the consolidated financial statements of the Company . In May 2014, the FASB issued a new standard (commonly referred to as ASC 606), which changed the way the Company recognizes revenue and significantly expanded the disclosure requirements for revenue arrangements. The Company adopted ASC 606 with a date of the initial application of January 1, 2018. As a result, the Company has change d its accounting policy for revenue recognition as detailed below. The Company applied ASC 606 using the full retrospective transition method. The Company elected the ASC 606 practical expedient and does not disclose the information about remaining perfor mance obligations that have original expected durations of one year or less. Amounts prior to January 1, 2018 that have been adjusted in accordance with ASC 606 as described herein are noted “as adjusted” . Previously, the Company recognized revenue from t he sale of manufactured products built to cus tomer specifications and other inventory when title and risk of ownership passed, the price to the buyer was fixed or determinable and recoverability was reasonably assured, which was generally when the goods we re shipped. Under ASC 606, the Company recognizes revenue as the customer takes control of the products. Under the majority of the Company’s manufacturing contracts with customers, the customer controls all of the work-in-progress as products are being bui lt. Revenues under these contracts are recognized progressively based on the cost-to-cost method. Accordingly, the Company will recognize revenue under these contracts earlier than under the previous accounting rules . The following tables summarize the im pacts of ASC 606 adoption on the Company’s 2017 and 2016 consolidated financial statements.

This guidance is effective January 1, 2019, with early adoption permitted. The Company is evaluating whether it will adopt this new guidance along with any impacts on the Company’s financial position, results of operations and cash flows, none of which are exp ected to be material. In June 2016, the FASB issued a new accounting standards update, which replaces the current incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This update is effective for annual reporting periods beginning after December 15, 2019 . The Company does not expect the implementation of this update to have a material impact on its consolidated financial position, results of operations or cash flows ; and will adopt this update effective January 1, 2020 . In February 2016, the FASB established Topic 842, Leases, and issued a new accounting standards u pdate (ASU) No. 2016-02, which re quires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10, Codification Improvements to Topic 842, Leases; and ASU No. 2018-11, Targeted Improvements. The new standard establishes a right-of-use model (ROU) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term long er than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The Company adopted the new standard on its effective date of January 1, 20 19 using the effective date as our date of initial application under the modified retrospective transition approach. Consequently, financial information will not be updated and the disclosures required under the new standard will not be provided for dates and p eriods before January 1, 2019. The new standard provides a number of optional practi cal expedients in transition. Management elected the ‘package of practic al expedients’, which permits the Company not to rea ssess under the new standard its prior conc lusions about lease identification, lease classificat ion and initial direct costs. Management do es not expect to elect the use-of-hindsight or the practical expedient pertaining to land easements; the l atter not being applicable to the Company . Management elect ed all of the new standard’s available tra nsition practical expedients. The Company has completed its preliminary assessment of adopting ASC 842 as of January 1, 2019. The adoption of the standard wi ll have a material effect on its financial statem ents. The most significant effects of adoption relate to (1) the recognition of new ROU ass ets and lease liabilities on the Company’s balance sheet for its real estate and equipment operating leases; and (2) providing significant new disclosures about our leasing activities beginning with the Quarterly Report on Form 10-Q f or the first quarter of 2019. Management do es not ex pect a significant change in the Company’s leasing activities as a result of the adoption. On adoption, the Company expect s to recogn ize additional operating liabilities in the range of approximately $ 85 million to $ 90 million , with corresponding ROU assets based on the presen t value of the remaining expected rental payments. The new standard also provides practical expedients for an e ntity’s ongoing accounting. Management currently expect s to elect the short-term lease re cognition exemption for all of the Company’s leases that qualify. This means, f or those leases that qualify, the Company will not recognize ROU assets or lease liabili ties, and this includes not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition. Th e Company also expect s to elect the practical expedient to not separate lease and non -lease components for all of its le ases other than leases of real estate. The Company has determined that other recently issued accounting standards will either have no material impact on its consolidated financial pos ition, results of operations or cash flows, or will not apply to its operat ions.

The U.S. Tax Reform reduced the U.S. corporate income tax rate from a maximum of 35% to a flat 21% rate, effective January 1, 2018 . The C ompany recorded the effects of the changes in the tax rate in our deferred tax assets and liabilities as of December 31, 2017 . To minimize tax base erosion with a territorial tax system, the U.S. Tax Reform enacted a new global intang ible low-taxed income (GILTI) provision that requires the Company to include in its U . S . income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiaries tangible assets. The taxable earnings can be offset by a lim ited deemed paid foreign tax credit with no carrybac ks or carryforwards available. The Company is su bject to the GILTI provisions. The Company elected to account for the GILTI as a period cost and include the effect in the period in which it is incurred an d not include it as a factor in the determination of deferred taxes . On December 22, 2017, additional guidance was issued on accounting for the tax effects of the U.S. Tax Reform ( Staff Accoun ting Bulletin No. 118 (SAB 118 ) ) . SAB 118 provided a measuremen t period that should not extend beyond one year from the U.S. Tax Reform enactment date for companie s to complete their accounting. The Company recorded a provisional tax expense of $101.6 million for the Transition Tax, and recognized a provisional deferr ed tax benefit of $3.9 million for a total net expense of $97.7 m illion as of December 31, 2017. As of December 31, 2018, the Company has completed the accounting for the tax effects of U.S. Tax Reform within the period required from the enactment date. Th e Company recognized during the fourth quarter of 2018 after filing its U.S. income tax return, a discr ete tax benefit adjustment of $6.4 million for the Transition Tax, and recorded a discrete tax expense adjustment of $2.0 million for the finalization of the deferred tax assets and liabilities for a net total adjustment of $4.4 million. These adjustments were based on additional analysis of undistributed cumulative foreign earnings, cumulative foreign taxes, changes in interpretations, and additional regu latory guidance that was issued during 2018 by the Internal Revenue Service (IRS) . As a result of the completed accounting for the Transition Tax, the Company determined that its total Transiti on Tax liability is currently $63.8 million after reduction fo r U.S. tax carryforward losses, U.S. tax credit carryforwards, and foreign tax credit carrybacks that are allowed to be utilized against the total liability. The Company intends to pay this liability over the remaining seven year payment period as prescrib ed by the U.S. Tax Reform and regulatory guidance issued by the IRS . $58.4 million of the Transition Tax liability is included in other long term liabilities. During 2018, the Company repatriated $560.6 million of foreign earnings to the U.S. As of December 31, 2018 , the Company has approximately $330 million in cumulative undistributed foreign earnings of its foreign subsidiaries. These earnings would not be subject to U.S. income tax, if distributed to the Company. The C ompany has changed its asser tion on its foreign subsidiaries earnings th at are permanently reinvested. A certain amount of earnings from specific foreign subsidiaries are permanently reinvested, and certain foreign earnings from other specific foreign subsidiaries is considered to be non-permanently reinvested and is available for immediat e distribution to the Company. Income taxes have been accrued on the non-permanently reinvested foreign earnings including the 2017 Transition Tax, the U.S. tax on Global Intangible Low Taxed Income (GILTI), and any applicable local withholding taxes. The Company estimates that it has approximately $2.3 million of unrecognized deferred tax liability related to any remaining undistributed foreign earnings that have not already been subject to the 2017 Transition Tax, the U.S. tax on GILTI, and any applicable foreign income tax or local withholding taxes on cash distributions . As a result of this change in assertion for undistributed earnings prior to December 31, 2017, the Company recorded a net tax ex pense of $21.6 million consisting of tax expense of $30.8 million relating to foreign withholding tax from Asia and a net benefit of $9.2 million for U.S. foreign tax credits to offset the foreign taxes paid during 2018. In addition, the Company recorded a pplicable U.S. state income tax expense net of federal benefits related to the cash repatriation. Also during 2018, the Company incurred a net $4.4 million benefit associated with finalizing the provisional impact of the U.S. Tax Reform described above as required by SAB 118, and incurred a $3.2 million tax expense as a result of GILTI . The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities are presented below: December 31, (in thousands) 2018 2017 (as adjusted) Deferred tax assets: Carrying value of inventories $ 2,787 $ 2,474 Accrued liabilities and allowances deductible for tax purposes on a cash basis 6,108 6,387 Goodwill 2,351 2,732 Stock-based compensation 2,347 2,359 Net operating loss carryforwards 20,028 22,096 Tax credit carryforwards 1,923 2,007 Other 4,373 5,924 39,917 43,979 Less: valuation allowance (13,709) (15,823) Net deferred tax assets 26,208 28,156 Deferred tax liabilities: Plant and equipment, due to differences in depreciation (7,617) (8,543) Intangible assets, due to differences in amortization (18,593) (20,891) ASC 606 revenue recognition (1,640) (1,667) Foreign withholding tax (9,212) - Other (991) (1,715) Gross deferred tax liability (38,053) (32,816) Net deferred tax liability $ (11,845) $ (4,660) The net deferred tax liability is classified as follows: Long-term asset $ 2,478 $ 4,034 Long-term liability (14,323) (8,694) Total $ (11,845) $ (4,660) All deferred taxes are classified as non-current on the balan ce sheet as of December 31, 2018 and 2017 . All deferred tax assets and liabilities are offset and presented as a single net noncurrent a mount by each tax jurisdiction . The net change in the total valuation allowance for 2018 , 2017 and 2016 was a $ 2.1 million decrease , a $ 0.2 million decrease and a $ 1.2 million decrease , respectively. In assessing the realizability of deferred tax assets, management considers whether it is more l ikely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences becom e deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxab le income over the periods which the deferred tax assets are deductible, management believes it is more likely than not the Company will realize the benefits of these deductible differences, net of the existing valuation allowances as of De cember 31, 2018 . As of December 31, 2018 , the Company had $ 24.4 million in U.S. Federal operating loss carryforwards which will expire from 202 5 to 203 6 ; state operating loss carryforwards of approximately $ 67.0 million which will expire from 201 9 to 2031 ; foreign operating loss carryforwards of approximately $ 24.8 million with indefinite carryforward periods; and foreign operating loss carryforwards of approximately $ 20.5 million which will expire at varying dates through 202 8 . The utilization of these net operatin g loss carryforwards is limited to the future operations of the Company in the tax jurisdictions in which such carryforwards arose. The Company has state tax credit carryforwards of $1.9 million which will expire at varying dates through 20 36 . The Company has been granted certain tax incentives, including tax holidays, for its subsidiaries in China, Malaysia and Thailand that will expire at various dates, unless extended or otherwise renegotiated, through 201 8 in China, 20 21 in Malaysia and 20 28 in Thailand, and are subject to certain conditions with which the Company expects to comply. The net impact of these tax incentives was to lower income tax expense for 2018 , 2017 , and 2016 by approximately $7.9 million (appr oximately $ 0.17 per diluted share), $7.2 million (approximately $ 0 . 15 per d iluted share) and $6.7 million (approximately $ 0. 13 per diluted share), respectively, as follows: Year Ended December 31, (in thousands) 2018 2017 2016 China $ 1,884 $ 1,398 $ 1,302 Malaysia 3,287 4,295 2,346 Thailand 2,715 1,545 3,068 $ 7,886 $ 7,238 $ 6,716 The Company must determine whether it is “more-likely-than-not” that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Once it is determined that a position meets the more-likely-than-not recognition threshold, the position is measured to determine the amount of benefit to recognize in the financial statements. As of December 31, 2018 , the total amount of the reserve for uncertain tax benefits in cluding interest and penalties wa s $0.4 million. A reconciliation of the beginning and ending amount of unrecognized tax benefits, excluding interest and penalties, is as follows: December 31, (in thousands) 2018 2017 2016 Balance as of January 1 $ 708 $ 7,791 $ 13,114 Additions related to current year tax positions 137 220 — Decreases as a result of a lapse of applicable statute of limitations in current year — — (5,079) Additions related to prior year tax positions — 894 89 Decreases related to prior year tax positions (532) (8,197) (333) Balance as of December 31 $ 313 $ 708 $ 7,791 During 2018 , the Company released $0.5 million of uncertain tax benefits from a n IRS audit related to the Secure Communication Systems, Inc. acquisition. During the first quarter of 2018 , the IRS indicated that this examination of years 2013 to 2015 was closed. In addition, the IRS also notified the Company that the examination of the Company’s consolidated U.S. income tax return filings for 2014 was also closed with no additional tax costs. During 2017 , the C ompany released $0.9 million of uncertain tax benefits related to the liquidation of a foreign subsidiary company. Also during 2017 , the Company received a denial of its appeal to the local tax authorities related to an examination for a subsidiary in T hailand for the years 2004 to 2005. Consequently, the Company recorded $0.9 million of additional accruals for uncertain tax benefits. The Company decided not to challenge this decision and therefore, the $7.3 million reserve for uncertain tax benefits was wr itten off . This decrease in the unrecognized tax benefit reserve did not impact the Company’s effective tax rate. The decrease in the reserve during 2016 of $5.1 million was a result of the expiration of the statute of limitations for a foreign subsidi ary that was liquidated in 2011 and closed its operations in 2005. The reserve is classified as a current or long-term liability in the consolidated balance sheet based on the Company’s expectation of when the items will be settled. The Company records in terest expense and penalties accrued in relation to uncertain income tax benefits as a component of current income tax expense. The amount of accrued potential interest on unrecognized tax benefits included in the reserve as of December 31, 2018 is $0.1 million. The reserve for potential penalties is $17.0 thousand. T he total amount of interest and penalties included in income tax expe nse was $0.1 million during 2018 . The Company did not incur any interest and penalti es in 2017 or 2016 . The Company and its subsidiaries in Braz il, China, Ireland, Malaysia, Mexico, the Netherlands, Romania, Singapore, Thailand and the United States remain open to examination by the various local taxing authorities, in total or in part, for fiscal years 2011 to 2018 . Currently, the Company does not have any ongoing income tax ex aminations by any jurisdiction. During the course of such income tax examinations, disputes may occur as to matters of fact or law. Also, in most tax jur isdictions, the passage of time without examination will result in the expiration of applicable statutes of limitations thereby precluding examination of the tax period(s) for which such statute of limitation has expired. The Company believes that it has a dequately provided for its tax liabilities.

Major Customers [Text Block]	Note 11 —Major Customers The Company’s customers operate in industries that are, to a varying extent, subject to rapid technological change, vigorous competition and short product life cycles. Developments adverse to the electronics industry, the Company’s customers or their products could impact the Company’s overall credit risk. The Company extends credit based on evaluation of its customers’ financial condition and generally does not require collateral or other security from its customers and w ould incur a loss equal to the carrying value of the accounts receivable if its customer failed to perform according to the terms of the credit arrangement.

Financial Instruments And Concentration Of Credit Risk [Abstract]
Financial Instruments And Concentration Of Credit Risk [Text Block]	Note 12 —Financial Instruments and Concentration of Credit Risk The Company’s financial instruments include cash equivalents, accounts and other receivables, accounts payable, accrued liabilities and long-term debt and capital lease obligations. The Company believes that the carrying values of these instruments approxi mate fair value . As of December 31, 2018 , the Company’s long-term investments and derivative instruments were recorded at fair value using Level 3 inputs. The Company uses derivat ive instruments to manage the variability of foreign currency obligations and interest rates. The Company does not enter into derivative arrangement s for speculative purposes . The forward currency exchange contract in plac e as of December 31, 2018 has not been designated as accounting hedges and, therefore, changes in fa ir value are recorded within the Con solidated Statements of Income. The Company has an interest rate swap agreement with a notional amount of $150.0 million as of December 31, 2018 t o hedge a portion of its interest rate exposure on outstanding borrowings under the Credit Agreement. Under this interest rate swap agreement, the Company receives variable rate interest rate payments based on the one-month LIBOR rate and pays fixed rate i nterest payments. The fixed interest rate for the contract is 2.928 %. The effect of this swap is to convert a portion of the floating rate interest expense to fixed interest rate expense. Based on the terms of the interest rate swap contract and the underl ying borrowings outstanding under the Credit Agreement, the interest rate contract was determined to be highly effective, and thus qualifies and has been designated as a cash flow hedge. As such, changes in the fair value of the interest rate swap are reco rded in other comprehensive income on the accompanying Condensed Consolidated Balance Sheets until earnings are affected by the variability of cash flows . As of December 31, 2017 , the Company had an interest rate swap agreement with a notional amount of $155.3 million with a fixed interest rate of 1.4935%. During 2018 , the Company terminated this agreement for $3.5 million and the gain is being amortized to offset interest expense over the original term of the swap agreement. The fair value of the i nterest rate swap agreements was a $3.0 million liability as of December 31, 2018 and a $2.0 million asset as of December 31, 201 7 . During th e year ended December 31, 2018 , the Company recorded unrealized losses of $1.5 million ($1.1 million net of tax) on the swap s in other comprehensive income and transferred unrealized gains of $0.3 million ($0.2 million net of tax) on the swaps to interest expense. During the year ended December 31, 2017 , the Company recorded unrealized gains of $1.5 milli on ($0.9 million net of tax) on the swap in other comprehensive income. See Note 21 . Financial instruments that subject the Company to credit risk consist of cash and cash equivalents, investments and trade accounts receivable. Management maintains the majority of the Company’s cash and cash equivalents with financial institutions. One of the most significant credit risks is the ultimate realization of accounts receivable. This risk is mitigated by (i) sales to well established companies, (ii) ongoi ng credit evaluation of customers, and (iii) frequent contact with customers, thus enabling management to monitor current changes in business operations and to respond accordingly. Management considers these concentrations of credit risks in establishing o ur allowance for doubtful accounts and believes these allowances are adequate. The Company had one customer whose gross accounts receivable exceeded 10% of total gross accounts receivable as of December 31, 2018 . Our largest customer represented 19% of our total gross accounts receivable.

Revenue From Contract With Customer [Abstract]
Revenue	Note 16 – Revenue The Company’s revenues are generated primarily from the sale of manufactured products bui lt to customer specifications. The Company also generates revenue from design, development and engineering services, in addition to the sale of other inventory. Revenue is measured based on the consideration specified in a contract with a customer. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a manufactured product to a customer. T he Company’s contracts with customers are generally short-term in nature. Customers are generally billed when the product is shipped or as services are performed. Under the majority of the Company’s manufacturing contracts with customers, the customer cont rols all of the work-in-progress as products are being built. Revenues under these contracts are recognized progressively based on the cost-to-cost method. For other manufacturing contracts, the customer does not take control of the product until it is com pleted. Under these contracts, the Company recognizes revenue upon transfer of control of the product to the customer . Revenue from design, development and engineering services is recognized over time as the services are performed. The Company assumes no s ignificant obligations after shipment as it typically warrants workmanship only. Therefore, the warranty provisions are generally not significant. If the Company records revenue, but does not issue an invoice, a contract asset is recognized. The contract asset is transferred to accounts receivable when the entitlement to payment becomes unconditional. Taxes assessed by governmental authorities that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as fulfillment costs and are included in cost of sales . Disaggregation of revenue In the following table s , revenue is d isaggregated by market sector. The table s also include a reconciliation of the disaggregated revenue with the reportable operating segments.

Restructuring Charges [Abstract]
Restructuring Charges	Note 19 —Restructuring Charges The Company has undertaken initiatives to restructure its business operations to improve utilization and realize cost savings. These initiatives have included changing the number and location of production facilities, largely to align capacity and infrastructure with current and anticipated customer demand. This alignment includes transferring programs from higher c ost geographies to lower cost geographies. The process of restructuring e ntails moving production between facilities, reducing staff levels, realigning our business processes, reorganizing our management and other activities. The Company recognized restru cturing charges during 2018 , 2017 and 2016 primarily related to the closure of facilities in the Americas, capacity reduction and reductions in workforce in certain facilities across various regions.

Summary Of Significant Accoun_2

Summary Of Significant Accounting Policies (Policy)	12 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
Principles of Consolidation	(b) Principles of Consolidation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) and include the financial statements of Benchmark Electronics, Inc. and its wholly owned and majority owned subsidiaries. All significant interc ompany balances and transactions have been eliminated in consolidation. Effective January 1, 2018, the Company adopted the requirements of a new a c counting standard related to revenue recognition as discussed in Note 1 (q) . All amounts and disclosures set forth in this Form 10-K have been updated to comply with the new standard, as indicated by the “as adjusted” column heading.
Cash And Cash Equivalents	(c) Cash and Cash Equivalents The Company considers all highly liquid debt instruments with an original maturity at the date of purchase of three months or less to be cash equivalents. Cash equivalents of $ 265.4 million and $ 581.4 million at December 31, 2018 and 2017 , respectively, consist ed primarily of money-market funds and time deposits with an initial term of less than three months.
Allowance For Doubtful Accounts	(d) Allowance for Doubtful Accounts Accounts receivable are recorded net of allowances for amounts not expected to be collected. In estimating the allowance, management considers a specific customer’s financial condition, payment history, and various information or disclosures by the customer or other publicly available information. Acco unts receivable are charged against the allowance after all reasonable efforts to collect the full amount (including litigation, where appropriate) have bee n exhausted. During both the third quarter of 2018 and the first quarter of 2017 , the Company recorded $ 1 .7 million in charge s for a provision to accounts receivable associated with the insolvency of two customer s .
Inventories	(e ) Inventories Inventories include material, labor and overhead and are stated at the lower of cost (principally first -in, first-out method) or net realizable value .
Property, Plant And Equipment	(f ) Property, Plant and Equipment Property, plant and equipment are stated at cost. Depreciation is calculated on the straight-line method over the useful lives of the assets – 5 to 40 years for buildings an d building improvements, 2 to 15 years for machinery and equipment, 2 to 12 years for furniture and fixtures and 2 to 8 years for vehicles. Leasehol d improvements are amortized on the straight-line method over the shorter of the useful life of the improvement or the remainder of the lease term.
Goodwill And Other Intangible Assets	(g ) Goodwill and Other Intangible Assets Goodwill represents the excess of purchase price over fair value of net assets acquired. Goodwill and intangible assets acquired in a business combination and determined to have an indefinite useful life are not amortized, but instead assessed for impairment at least annually. Intangible assets , including those acquired in a business combination, with estimable useful liv es are amortized over their respective estimated useful lives to their estimated residual values.
Impairment Of Long-Lived Assets And Goodwill	(h ) Impairment of Long-Lived Assets and Goodwill Long-lived assets, such as property, plant, and equipment, and purchased intangibles subject to amortizatio n, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is evaluated by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated undiscounted future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the a sset exceeds the estimated fair value of the asset. Assets to be disposed of would be separately disclosed and reported at the lower of the carrying amount or estimated fair value less costs to sell, and are no longer depreciated. The assets and liabilitie s of a disposed group classified as held for sale would be disclosed separately in the appropriate asset and liability sections of the consolidated balance sheet. Goodwill is tested for impairment on an annual basis, during the fourth quarter , and whenever events and changes in circumstances suggest that the carrying amount may be impaired. Circumstances that may lead to the impairment of goodwill include unforeseen decreases in future performance or industry demand or the restructuring of our operations as a result of a change in our business strategy. A qualitative assessment is allowed to determine if goodwill is potentially impaired. Based on this qualitative assessment, if the Company determines that it is more likely than not that the reporting unit’s fair value i s less than its carrying value, then it performs a two-step goodwill impairment test, otherwise no further analysis is required. In connection with its annual qualitative goodwill impairment assessments as of December 31, 2018 , 2017 and 2016 , the Company con cluded that goodwill was not impaired.
Earnings (Loss) Per Share	(i ) Earnings (Loss) Per Share Basic earnings per share is computed using the weighted-average number of shares outstanding. Diluted earnings per share is computed using the weighted-average number of shares outstanding adjusted for the incremental shares attributed to outstanding stock equivalents. Stock equivalents include common shares issuable upon the exercise of stock options and other equity instruments, and are computed using the treasury stock method. Under the treasury stock method, the exercise price of a share, the amount of compensation cost, if any, for future service that the Company has not yet recognized are assumed to be used to rep urchase shares in the current period. The following table sets forth the calculation of basic and diluted earnings (loss) per share. Year Ended December 31, (in thousands, except per share data) 2018 2017 2016 (as adjusted) Net income (loss) $ 22,817 $ (31,901) $ 63,933 Denominator for basic earnings per share – weighted-average number of common shares outstanding during the period 46,332 49,680 49,298 Incremental common shares attributable to exercise of dilutive options 104 — 313 Incremental common shares attributable to outstanding restricted stock units 219 — 214 Denominator for diluted earnings per share 46,655 49,680 49,825 Basic earnings (loss) per share $ 0.49 $ (0.64) $ 1.30 Diluted earnings (loss) per share $ 0.49 $ (0.64) $ 1.28 Potentially dilutive securities totaling 0.6 million common shares in 2017 were not included in the computation of diluted loss per share because their effect would have decreased the loss per share. Options to purchase 0.4 mi llion common shares in 2016 were not included in the computation of diluted earnings per share because their effect would have been anti-dilutive.
Revenue Recognition	(j ) Revenue Recognition T he Company recognizes revenue as the customer takes control of the manufacture d products built to customer specifications. Under the majority of the Company’s manufacturing contracts with customers, the customer controls all of the work-in-progress as products are being built. Revenues under these con tracts are recognized over time based on the cost-to-cost method. Under other manufacturing contracts, the customer does not take control of the product until it is completed. Under these contracts, the Company continues to recognize revenue upon transfer of control of product to the cus tomer , which is generally when the goods are shipped . Revenue from design, development and engineering services also continues to be recognized over time as the services are performed . The Company’s performance obligations generally have an expected duration of one year or less. The Company applies the practical expedients and does not disclose information about remaining performance obligations that have original expected durations of one year or less or any significant financing components in the co ntracts. The Company recognizes the incremental costs, if any, of obtaining contracts as an expense when incurred since the amortization period of the assets that the Company otherwise would have recognized is one year less.
Income Taxes	( k ) Income Taxes Income taxe s are accounted for under the asset and liability method. Deferred income taxes are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respect ive tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. The Company records a valuation allowance to reduce its deferred tax assets to the amounts that are more likely than not to be realized. The Company has considered the sch eduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in assessing the need for the valuation allowance.
Stock-Based Compensation	(l ) Stock-Based Compensation All share-based payments to employees, including grants of employee stock options (which have not been awarded since 2015) , are recognized in the financial statements based on their grant date fair values. The total compensation cost recognized for stock-based awards was $10.1 million, $7.8 million and $5.3 million for 2018 , 2017 and 2016 , respectively. The total income tax benefit recognized in the income statement for stock-based awards was $2.4 million, $2.8 million and $1.1 million for 2018 , 2017 and 2016 , respecti vely. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. Awards of restricted stock units and performance-based restricted stock units are valued at the closing market price of the Company’s common stock on the date of grant. For performance-based restricted stock units, compensation expense is based on the probability that the performance goals will be achieved, which is monitored by management throughout the requisite service period. When it becomes probable, based on the Company’s expectation of performance during the measurement period, that more or less than the previous estimate of the awarded shares will vest, an adjustment to stock-based compensation expense is recognized as a change in accounting estimate . As of December 31, 2018 , the unrecognized compensation cost and remaining weighted-average amortization related to stock-based awards were as follows: Performance- based Restricted Restricted Stock Stock Stock (in thousands) Options Units Units (1) Unrecognized compensation cost $ 44 $ 12,738 $ 2,461 Remaining weighted-average amortization period 0.2 years 2.4 years 1.2 years (1) Based on the probable achievement of the performance goals identified in each award. The total cash received as a result of stock option exercises in 2018 , 2017 and 2016 was approximately $3.6 million, $11.2 million and $18.8 million, respectively. The actual tax benefit realized as a result of stock option exercises and the vesting of other share-based awards during 2018 , 2017 and 2016 was $2.5 million, $5.0 million and $3.7 million, respectively. For 2018 , 2017 and 2016 , the total intrinsic value of stock options exercised was $2.3 million, $7.7 million and $5.1 million, respectively. The Company awarded performance-based restricted stock units to employees during 2018 , 2017 and 2016 . The number of performance-based restric ted stock units that will ultimately be earned will not be determined until the end of the corresponding performance periods, and may vary from as low as zero to as high as 2.5 times the target number depending on the level of achievement of certain perfor mance goals. The level of achievement of these goals is based upon the financial results of the Company for the last full calendar year within the performance period. The performance goals consist of certain levels of achievement using the following financ ial metrics: revenue growth, operating margin expansion, and return on invested capital. If the performance goals are not met based on the Company’s financial results, the applicable performance-based restricted stock units will not vest and will be forfei ted. Shares subject to forfeited performance-based restricted stock units will be available for issuance under the Company’s 2010 Omnibus Incentive Compensation Plan (the 2010 Plan).
Use Of Estimates	(m ) Use of Estimates Management of the Company has made a number of est imates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities to prepare these financial statements in accordance with U.S. GAAP. On an ongoing basis, management evaluates these estimates , including those related to accounts receivable, inventories, income taxes, long-lived assets, stock-based compensation a nd contingencies and litigation . Actual results could differ from those estimates.
Fair Values Of Financial Instruments	(n ) Fair Values of Financial Instruments Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A three-tier fair value hierarchy of inputs is employed to determine fair value measurements. Level 1 inputs are quoted prices (unadjusted) in active markets for id entical assets and liabilities. Level 2 inputs are observable prices that are not quoted on active exchanges, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; and model-derived valuations whose inputs are observable or whose significan t value drivers are observable. Level 3 inputs are unobservable inputs employed for measuring the fair value of assets or liabilities. This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. T he Company’s f inancial instruments include cash equivalents, accounts and other receivables, accoun ts payable, accrued liabilities and long-term debt and capital lease obligations. The Company believes that the carrying values of these instruments approxim ate their fair value. As of December 31, 2018 , all of the Company’s long-term investments and derivative instruments were recorded at f air value using Level 3 inputs. See Note 12 .
Foreign Currency	(o ) Foreign Currency For foreign subsidiaries using the local currency as their functional currency, assets and liabilities are translated at exchange rates in effect at the balance sheet date and income and expenses are translated at average exchange rates. The effects of these translation adjustments are reported i n other comprehensive income. Exchange losses arising from transactions denominated in a currency other than the functional currency of the entity involved are included in other expense and totaled approximately $ 1.0 million, $ 2.1 million and $ 0.5 million in 2018 , 2017 and 2016 , respectively . These amounts include the amount of gain (loss) recognized in income due to forward currency exchange contract s.
Derivative Instruments	(p ) Derivative Instruments All derivative instruments are recorded on the balance sheet at fa ir value. The Company uses derivative instruments to manage the variability of foreign currency obligations and interest rates . The Company does not enter into derivative arrangements for speculative purposes . Generally, if a derivative instrument is desig nated as a cash flow hedge, the change in the fair value of the derivative is recorded in other comprehensive income to the extent the derivative is effective, and recognized in the consolidated statement of i ncome when the hedged item affects earnings. Ch anges in fair value of derivatives that are not designated as hedges are recorded in earnings. Cash receipts and cash payments related to derivative instruments are recorded in the same category as the cash flows from the items being hedged on the c onsolid ated s tatements of c ash f lows.
New Accounting Pronouncements	(q) New Accounting Pronouncements Adopted in 2018 In May 2017, the Financial Accounting Standards Board (FASB) issued a new accounting standards update that provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The Company adopted the new guidance effective January 1, 2018. The impact of adoption on the Company's consolidated financial statements is dependent on future c hanges to stock-based compensation awards . In August 2016, the FASB issued a new accounting standards update, which seeks to reduce the existing diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The Company adopted this new update effective January 1, 2018. The adoption of this guidance had no impact on the consolidated financial statements of the Company . In May 2014, the FASB issued a new standard (commonly referred to as ASC 606), which changed the way the Company recognizes revenue and significantly expanded the disclosure requirements for revenue arrangements. The Company adopted ASC 606 with a date of the initial application of January 1, 2018. As a result, the Company has change d its accounting policy for revenue recognition as detailed below. The Company applied ASC 606 using the full retrospective transition method. The Company elected the ASC 606 practical expedient and does not disclose the information about remaining perfor mance obligations that have original expected durations of one year or less. Amounts prior to January 1, 2018 that have been adjusted in accordance with ASC 606 as described herein are noted “as adjusted” . Previously, the Company recognized revenue from t he sale of manufactured products built to cus tomer specifications and other inventory when title and risk of ownership passed, the price to the buyer was fixed or determinable and recoverability was reasonably assured, which was generally when the goods we re shipped. Under ASC 606, the Company recognizes revenue as the customer takes control of the products. Under the majority of the Company’s manufacturing contracts with customers, the customer controls all of the work-in-progress as products are being bui lt. Revenues under these contracts are recognized progressively based on the cost-to-cost method. Accordingly, the Company will recognize revenue under these contracts earlier than under the previous accounting rules . The following tables summarize the im pacts of ASC 606 adoption on the Company’s 2017 and 2016 consolidated financial statements.

This guidance is effective January 1, 2019, with early adoption permitted. The Company is evaluating whether it will adopt this new guidance along with any impacts on the Company’s financial position, results of operations and cash flows, none of which are exp ected to be material. In June 2016, the FASB issued a new accounting standards update, which replaces the current incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This update is effective for annual reporting periods beginning after December 15, 2019 . The Company does not expect the implementation of this update to have a material impact on its consolidated financial position, results of operations or cash flows ; and will adopt this update effective January 1, 2020 . In February 2016, the FASB established Topic 842, Leases, and issued a new accounting standards u pdate (ASU) No. 2016-02, which re quires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10, Codification Improvements to Topic 842, Leases; and ASU No. 2018-11, Targeted Improvements. The new standard establishes a right-of-use model (ROU) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term long er than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The Company adopted the new standard on its effective date of January 1, 20 19 using the effective date as our date of initial application under the modified retrospective transition approach. Consequently, financial information will not be updated and the disclosures required under the new standard will not be provided for dates and p eriods before January 1, 2019. The new standard provides a number of optional practi cal expedients in transition. Management elected the ‘package of practic al expedients’, which permits the Company not to rea ssess under the new standard its prior conc lusions about lease identification, lease classificat ion and initial direct costs. Management do es not expect to elect the use-of-hindsight or the practical expedient pertaining to land easements; the l atter not being applicable to the Company . Management elect ed all of the new standard’s available tra nsition practical expedients. The Company has completed its preliminary assessment of adopting ASC 842 as of January 1, 2019. The adoption of the standard wi ll have a material effect on its financial statem ents. The most significant effects of adoption relate to (1) the recognition of new ROU ass ets and lease liabilities on the Company’s balance sheet for its real estate and equipment operating leases; and (2) providing significant new disclosures about our leasing activities beginning with the Quarterly Report on Form 10-Q f or the first quarter of 2019. Management do es not ex pect a significant change in the Company’s leasing activities as a result of the adoption. On adoption, the Company expect s to recogn ize additional operating liabilities in the range of approximately $ 85 million to $ 90 million , with corresponding ROU assets based on the presen t value of the remaining expected rental payments. The new standard also provides practical expedients for an e ntity’s ongoing accounting. Management currently expect s to elect the short-term lease re cognition exemption for all of the Company’s leases that qualify. This means, f or those leases that qualify, the Company will not recognize ROU assets or lease liabili ties, and this includes not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition. Th e Company also expect s to elect the practical expedient to not separate lease and non -lease components for all of its le ases other than leases of real estate. The Company has determined that other recently issued accounting standards will either have no material impact on its consolidated financial pos ition, results of operations or cash flows, or will not apply to its operat ions.

Credit Agreement description	On July 20, 2018, the Company entered into a $650 million credit agreement (the Credit Agreement) by and among the Company, certain of its subsidiaries, the lenders party thereto and Bank of America, N.A., as Administrative Agent, Swingline Lender and a L/C Issuer. The Credit Agreement is comprised of a five-year $500 million revolving credit facility (the Revolving Credit Facility) and a five-year $150 million term loan facility (the Term Loan Facility), both with a maturity date of July 20, 2023. The Term Loan Facility proceeds were used to (i) refinance a portion of existing indebtedness and terminate all commitments under the Company’s prior $430 million Credit Agreement and (ii) pay the fees, costs and expenses associated with the foregoing and the negotiation, execution and delivery of the Credit Agreement. The Revolving Credit Facility is available for general corporate purposes. The Credit Agreement includes an accordion feature pursuant to which the Company is permitted to add one or more incremental term loan and/or increase commitments under the Revolving Credit Facility in an aggregate amount not exceeding $275 million, subject to the satisfaction of certain conditions.

Concentration Risk [Line Items]
Concentration Risk Customer Accounts Receivable		One of the most significant credit risks is the ultimate realization of accounts receivable. This risk is mitigated by (i) sales to well established companies, (ii) ongoing credit evaluation of customers, and (iii) frequent contact with customers, thus enabling management to monitor current changes in business operations and to respond accordingly. Management considers these concentrations of credit risks in establishing our allowance for doubtful accounts and believes these allowances are adequate. The Company had one customer whose gross accounts receivable exceeded 10% of total gross accounts receivable as of December 31, 2018.
