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 worldwide integrated electronic manufacturing services (EMS) , engineering and design services, and precision machining services . The Company provides services to original equipment manufacturers (OEMs) in the following industries: industrial contr ol s, aerospace and defense (A&D) , telecommunication s , computers and related products for busin ess enterprises, medical devices , and testing and instrumentation. 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 intercompany balances and transactions have been eliminated in consolidation. (c) Cash and Cash Equivalents The Company considers all highly liquid debt instruments wi th an original maturity at the date of purchase of three months or less to be cash equivalents. Cash equivalents of $ 581.4 million and $ 531.8 million at December 31, 2017 and 2016 , respectively, consist ed primarily of money-market funds and time depo sits 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 f inancial 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 li tigation, where appropriate) have been exhausted. During 2017 , the Company recorded a $ 1 .7 million charge for provisions to accounts receivable associated with the insolvency of a customer. (e ) Inventories Inventories include material, labor and overhead and are stated at the lower of cost (principally first-in, first-out method) or market. (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. Leasehold 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 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 amortization , 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 as set 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 liabilities 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, at a minimum, and whenever events and c hanges 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 is 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 goodwill impairment assessments as of December 31, 2017 , 2016 and 2015 , the Company conc luded that goodwill was not impaired. (i ) Earnings 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 instrume nts, 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 repurchase 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) 2017 2016 2015 Net income (loss) $ (31,965) $ 64,047 $ 95,401 Denominator for basic earnings per share – weighted-average number of common shares outstanding during the period 49,680 49,298 51,573 Incremental common shares attributable to exercise of dilutive options — 313 318 Incremental common shares attributable to outstanding restricted stock units — 214 197 Denominator for diluted earnings per share 49,680 49,825 52,088 Basic earnings (loss) per share $ (0.64) $ 1.30 $ 1.85 Diluted earnings (loss) per share $ (0.64) $ 1.29 $ 1.83 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 million and 1.3 mi llion common shares in 2016 and 2015 , respectively, were not included in the computation of diluted earnings per share because their effect would have been anti-dilutive. (j ) Revenue Recognition Revenue from the sale of manufact ured products built to customer specifications and excess inventory is recognized when title and risk of ownership have passed, the price to the buyer is fixed or determinable and recoverability is reasonably assured, which generally is when the goods are shipped. Revenue from design, development and engineering services is recognized when the services are performed and collectibility is reasonably certain. Such services provided under fixed price contracts are accounted for using the percentage-of-completi on method. The Company assumes no significant obligations after shipment as it typically warrants workmanship only. Therefore, the warranty provisions are generally not significant. ( k ) Income Taxes Income taxes are accounted for under the asset and liab ility 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 respective tax bases. Deferred tax assets and liabi lities 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 scheduled 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, are recognized in the financia l statements based on their grant date fair values. The total compensation cost recognized for stock-based awards was $7.8 million, $5.3 million and $7.7 million for 2017 , 2016 and 2015 , respectively. The total income tax benefit r ecognized in the income statement for stock-based awards was $2.8 million, $1 . 1 million and $3.1 million for 2017 , 2016 and 2015 , respectively. The compensation expense for stock-based awards is recognized over the vesting per iod of the awards using the straight-line method. Awards of restricted shares, restricted stock units and performance-based restricted stock units are valued at the closing market price of the Company’s common shares on the date of grant. For performance-b ased 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 expectatio n of performance during the measurement period, that more or less than the previous estimate of the awarded shares will vest, an adjustment to stock-ba sed compensation expense is recognized as a change in accounting estimate. As of December 31, 2017 , 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 $ 535 $ 10,738 $ 3,345 Remaining weighted-average amortization period 0.6 years 2.2 years 1.8 years (1) Based on the probable achievement of the performance goals identified in each award. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. The weighted-average fair value per option granted during 2015 was $8.76. No options were granted during 2017 or 2016 . The weighted-average assumptions used to value the options granted during the year ended December 31, 2015 were as follows: (in thousands) Options granted 289 Expected term of options 6.4 years Expected volatility 35% Risk-free interest rate 1.886% Dividend yield zero The expected term of the options represents the estimated period of time until exercise and is based on historical experience, giving consideration to the contractual terms, vesting schedules and expectations of future plan participant behavior. Separate groups of plan participants that have similar historical exercise behavior are considered separately for valuation purposes. Expected stock price volatility is based on the historical volatility of the Company’s common shares. The risk-free interest rate i s based on the U.S. Treasury zero-coupon rates in effect at the time of grant with an equivalent remaining term. The dividend yield reflects that the Company has not paid any cash dividends since inception and does not anticipate paying cash dividends in t he foreseeable future . The total cash received as a result of stock option exercises in 2017 , 2016 and 2015 was approximately $11.2 million, $18.8 million and $2.0 million, respectively. The actual tax benefit realized as a result of stock option exercises and the vesting of other share-based awards during 2017 , 2016 and 2015 was $5.0 million, $3.7 million and $2.1 million, respectively. For 2017 , 2016 and 2015 , the total intrinsic value of stock options exercised was $7.7 million, $5.1 million and $0.7 million, respectively. The Company awarded performance-based restricted stock units to employees during 2017 , 2016 and 2015 . The number of performan ce-based restricted 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 o f certain performance 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 financial 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 an d will be forfeited. 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 ma de a number of estimates 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 evaluat es 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 Inst ruments 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 drive rs 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. The 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 approximate their fair value. As of December 31, 2017 , all of the Company’s long-term investments and derivative instruments were recorded at f air value using Level 3 inputs. See Note 11 . (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 translati on adjustments are reported in 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 $ 2.1 million, $ 0.5 million and $ 2.3 million in 2017 , 2016 and 2015 , 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 recorde d on the balance sheet at fair 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 de rivative instrument is designated 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 hedg ed item affects earnings. Changes 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 2017 Effective January 1, 2017, the Company adopted a new accounting standard s update that simplifies several aspects of the accounting for employee share-based payment transactions, including accounting for income taxes, forfeitures, and statutory withholding requirements, as well as classification in the Consolidated Statements of Cash Flows. As required by this standard, excess tax benefits recognized on stock-based compensation expense are reflected in the accompanying Consolidated Income Statement as a component of the provision for income taxes on a prospective basis (See Note 9 ). As a result of including the income tax effects from excess tax benefits in income tax expense, the effects of the excess tax benefits are no longer included in the calculation of diluted shares outstanding, resulting in an increase in the number of diluted shares outstanding. The Company adopted this change in the method of calculating diluted shares outstanding on a prospective basis. Additionally, excess tax benefits or deficiencies recognized on stock-based compensation expense are classified as an operating activit y in the accompanying Consolidated Statements of Cash Flows. The Company has applied this provision prospectively. Additionally, the Company is now required to present the cost of shares withheld from the employee to satisfy the empl oyees’ income tax liability as a financing activity on the statement of cash flows rather than as an operating cash flow. The Company adopted this change r etrospectively. As a result, in both of the years ended December 31, 2016 and 2015 , net cash pr ovided by operations increased by $0.6 million with a corresponding offset to net cash used in financing activities. The standard also allows for the option to account for forfeitures as they occur when determining the amount of compensation cost to be rec ognized, rather than estimating expected forfeitures over the course of a vesting period. The Company elected to account for forfeitures as they occur. The net cumulative effect to the Company from the adoption of this accounting standard update was an inc rease to paid-in capital of $0.2 million and a reduction to retained earnings of $0.2 million. Effective January 1, 2017 , the Company adopted an accounting standards update which applies to inventory that is measured using first-in, first-out or average c ost, with new guidance on simplifying the measurement of inventory. Inventory within the scope of this update is required to be measured at the lower of its cost or net realizable value, with net realizable value being the estimated selling price in the or dinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The adoption of this update by the Company did not have a material impact on the Company’s consolidated financial statements . 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. This up date is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017, with early adoption permitted. The Company is evaluating the impact of the adoption of this guidance on its consolidated financial sta tements and related disclosures but does not expect it to have a material impact. The Company adopted the new guidance effective January 1, 2018. In August 2016, the FASB issued a new accounting standards update, which seeks to reduce the existing diversi ty 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. In May 2014, the FASB issued a new standard (commonly referred to as ASC 606) , wh ich will change the way the Company recognizes revenue and significantly expands the disclosure requirements for revenue arrangements. The new standard is effective for annual reporting periods beginning after December 15, 2017. The Company adopted the re quirements of the new standard on January 1, 2018 using the full retrospective transition method . We will adjust prior period consolidated financial statements to reflect full retrospective adoption beginning with the Quarterly Report on Form 10-Q for the first quarter of 2018. As ASC 606 supersedes substantially all existing revenue guidance affecting the Company under current U.S. GAAP, it will impact revenue and cost recognition across its business, as well as its business processes. The Company has subs tantially completed the implementation of changes to internal controls over financial reporting to allow the Company to timely compile the information needed to account for transactions under this new guidance and to adjust its prior periods’ consolidated financial statements . Under ASC 606, revenue will be recognized as or when the customer obtains control of the goods or services promised in the contract. Given the nature of the terms and conditions in substantially all of the Company’s customer contract s, the customer obtains control as the Company per forms work under the contract. For these contracts, the Company expects t o recognize revenue over time. Revenue for all other goods will be recognized at a point in time, upon transfer of control of the pro duct to the customer (i.e., effectively no change to current accounting). The Company currentl y recognizes the majority of its manufacturing revenue when title and risk of ownership have passed, the price to the buyer is fixed or determinable and recovera bility is reasonably assured, which generally is when the goods are shipped. Under ASC 606, the Company will recognize revenue over time for a significant majority of its manufacturing contracts. This will change the timing of revenue recognition for a sig nificant portion of the Company’s business, whereby revenue will be recognized earlier than under the current accounting rules. ASC 606 will also have material impacts to the Company’s balance sheet, primarily related to a reduction in finished goods and w ork-in-process inventories and an increase in contract assets . The Company has completed its preliminary assessment of adopting ASC 606 on the Company’s 2017 and 2016 operating results, which will reduce diluted earnings per share by approximately $ 0.02 f or 2017 and increase diluted earnings per share by approximately $ 0.02 for 2016. The impact of adopting ASC 606 on the Company’s 2017 and 2016 operating results may not be indicative of the adoption imp acts in future periods or of its operating performance . Total net cash provided by operating activities and net cash used by investing and financing activities on its consolidated statements of cash flows will not be impacted by the adoption of ASC 606 . Not Yet Adopted In February 2018, the FASB issued new accounting guidance on the reclassification of certain tax effects from accumulated other comprehensive income to retained earnings. This optional guidance is effective January 1, 2019, with early adoption permitted. The Company is eval uating whether it wi ll adopt this new guidance along with any impacts on the Company’s financial position, results of operations and cash flows, none of which are expected 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 annua l 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. In February 2016, the FASB issued a new accounting standards update changing the accounting for leases and including a requirement to record all leases on the consolidated balance sheets as assets and liabilities. This update is effective for fiscal years beginning after December 15, 2018. The Company will adopt this update effective January 1, 2019, which will impact its consolidated balance sheet. The Company is currently evaluating the impact this standard will have on its consolidated financial statements. The Company has determined tha t all other recently issued accounting standards will not have a material impact on its consolidated financial position, results of operations and cash flows, or do not apply to its operations.

The Tax Reform Act reduces the U.S. corporate income tax rate from a maximum of 35% to a flat 21% rate, effective January 1, 2018. Under the accounting rules, companies are required to recognize the effects of changes in tax laws and tax rates on deferred tax assets and liabilities in the period in which the new legislation is enacted. As of December 31, 2017, the Company had approximately $928 million in cumulative undistributed foreig n earnings outside the U.S. A ll of these undistributed earnings are subjec t to the U.S. mandatory transi tion tax and are eligible to be repatriated to the U.S. without additional U.S. tax under the U.S. Tax Reform. As of December 31, 2017, the Company has provisional income tax expense of $ 101.6 million for the estimated mandatory deemed repatriation of undistributed foreign earnings. After reduction by U.S. tax loss carryforwards and U.S. tax credit carryforwards, the Company accrued U.S. income tax liabil ities of $ 87.7 million in 2017. The Company intends to pay this estimated tax liability over an eight-year payment schedule as prescribed by the U.S. Tax Reform . As such, other long-term liabilities includes $ 80.7 million of this estimated liability . Thoug h these foreign earnings have been deemed to be repatriated from a U.S. federal tax perspective, the Company has not yet completed its assessment of the U.S. Tax Reform on its plans to reinvest foreign earnings and as such has not changed its prior conclus ion that the earnings are indefinitely reinvested. The repatriation tax is based on currently available information and technical guidance related to the new tax law. The provisional estimate will be updated when additional information related to undistrib uted foreign earnings, foreign taxes and foreign cash and equivalents becomes available, prepared and analyzed. In addition, as a result of the reduction in the U.S. corporate income tax rate from 35% to 21%, the Company remeasured its ending net deferred tax liabilities at December 31, 2017 a nd recognized a provisional $ 3.9 million deferred tax benefit. Given the significance of the legislation, the SEC staff issued Staff Accounting Bulletin No. 118 (SAB 118), which provides guidance on accounting for th e tax effects of the Tax Reform Act. SAB 118 provides a measurement period that should not extend beyond one year from the U.S. Tax Reform enactment date for companies to complete their accounting. The Company has recognized the provisional tax impacts rel ated to deemed repatriated earnings and the revaluation of deferred tax assets and liabilities and included these amounts in its consolidated financial statements for the year ended December 31, 2017. These preliminary estimates are subject to the finaliza tion of management’s analysis related to certain matters, such as developing interpretations of the provisions of the U.S. Tax Reform, changes to certain estimates and amounts related to the earnings and profits of certain subsidiaries and the filing our t ax returns. U.S. Treasury regulations, administrative interpretations or court decisions interpreting the U.S. Tax Reform may require further adjustments and changes in the Company’s estimates. The Company will finalize its accounting of the impact no late r than the fourth quarter of 2018 . 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) 2017 2016 Deferred tax assets: Carrying value of inventories $ 2,474 $ 2,400 Accrued liabilities and allowances deductible for tax purposes on a cash basis 6,387 5,663 Goodwill 2,732 4,814 Stock-based compensation 2,359 3,856 Net operating loss carryforwards 22,096 38,988 Tax credit carryforwards 2,007 8,688 Other 5,924 6,812 43,979 71,221 Less: valuation allowance (15,823) (16,026) Net deferred tax assets 28,156 55,195 Deferred tax liabilities: Plant and equipment, due to differences in depreciation (8,543) (11,499) Intangible assets, due to differences in amortization (20,891) (35,492) Other (1,715) (1,632) Gross deferred tax liability (31,149) (48,623) Net deferred tax asset (liability) $ (2,993) $ 6,572 The net deferred tax asset (liability) is classified as follows: Long-term asset $ 4,034 $ 6,572 Long-term liability (7,027) — Total $ (2,993) $ 6,572 All deferred taxes are classified as non-current on the balan ce sheet as of December 31, 2017 and 2016 . All deferred tax assets and liabilities are offset and presented as a single net noncurrent a mount by each tax jurisdiction. During 2017 , the Company utilized it s U.S. federal tax loss carryforwards, and various US federal tax credit carryforwards against the provisional mandatory deemed repatriation tax. The net change in the total valuation allowance for 2017 , 2016 and 2015 was a de crease of $ 0.2 million, $ 1.2 million and $ 19.5 million, respectively. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. T he ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, pro jected future taxable income and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods which the deferred tax assets are deductible, management believ es 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, 2017 . During 2015 , the Company evaluated the recoverability of its deferred tax assets u sing the criteria described above and concluded that the Company’s projected future taxable income in the U.S. is sufficient to utilize additional net operating loss carryforwards and other deferred tax a ssets. As a result, during 2015 , the Company red uced its valuation allowance by $ 19.6 million. As of December 31, 2017 , the Company had $ 32.4 million in U.S. Federal operating loss carryforwards which will expire from 202 5 to 203 6 ; state operating loss carryforwards of approximately $ 77.5 million w hich will expire from 201 8 to 2031 ; foreign operating loss carryforwards of approximately $ 24.6 million with indefinite carryforward periods; and foreign operating loss carryforwards of approximately $ 25.7 million which will expir e at varying dates through 202 7 . The utilization of these net operating 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 $2.0 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 incom e tax expense for 2017 , 2016 , and 2015 by approximately $7.2 million (approximately $ 0.15 per diluted share), $6 .7 million (approximately $ 0 . 13 per d iluted share) and $13.7 million (approximately $ 0. 26 per dil uted share), respectively, as follows: Year Ended December 31, (in thousands) 2017 2016 2015 China $ 1,398 $ 1,302 $ 5,347 Malaysia 4,295 2,346 2,075 Thailand 1,545 3,068 6,271 $ 7,238 $ 6,716 $ 13,693 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, 2017 , the total amount of the reserve for uncertain tax benefits in cluding interest and penalties wa s $ 0.8 million. A reconciliation of the beginning and ending amount of unrecognized tax benefits, excluding interest and penalties, is as follows: December 31, (in thousands) 2017 2016 2015 Balance as of January 1 $ 7,791 $ 13,114 $ 14,756 Additions related to current year tax positions 220 — — Decreases as a result of a lapse of applicable statute of limitations in current year — (5,079) (1,653) Additions related to prior year tax positions 894 89 800 Decreases related to prior year tax positions (8,197) (333) (789) Balance as of December 31 $ 708 $ 7,791 $ 13,114 During 2017 , the Company 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 Thailand 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, therefore, the $7.3 million reserve for uncertain tax benefits was written 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 l imitations for a foreign subsidiary that was liquidated in 2011 and closed its operations in 2005. The decrease in the reserve during 2015 of $1.7 million wa s the result of the expiration of the statute of limitations for a dormant foreign subsidiary i n Thailand. 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 interest expense and penalties accrued in relation to unc ertain 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, 2017 is $ 0.1 million. There was no reserve for potential penalties . The decrease in the reserve relating to interest and penalties on unrecognized tax benefits from $3.3 million in 2015 to $0.1 million in 2016 results from the corresponding reduction for the Thailand subsidiary discussed above. The total amount of interest and penalties included in income tax expe nse was $0.1 million during 2015 . The Company did not incur any interest and penalties in 2017 or 2016 . The Company and its subsidiaries in Brazil, China, Ireland, Luxembourg, Malaysia, Mexico, t he 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 y ears 2011 to 2017 . The Company is currently under examination by the U.S. Internal R evenue Service for 2014. In addition, Secure Communication Systems, Inc. and its subsidiaries (the Secure Group), companies that the Company acquired on November 11, 2015, are under a U.S. income tax audit for calendar years 2013, 2014 and through November 11, 2015. Since this audit is for the period of time prior to the acquisition of the Secure Group by the Company, any resulting tax liabilities are the responsibility of the seller. The Company does not expect to incur any income tax costs with respect to this audit. During the course of such examinations, disputes may occur as to matters of fact or law. Also, in most tax jurisdictions, the passage of time without examination will result in the expiration of applicable statutes of limitations thereby pre cluding examination of the tax period(s) for which such statute of limitation has expired. The Company believes that it has adequately provided for its tax liabilities.

Major Customers [Abstract]
Major Customers [Text Block]	Note 10 —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. Sales to the ten largest custo mers represented 46%, 43% and 47 % of total sales for 2017 , 2016 and 2015 , respectively.

Financial Instruments And Concentration Of Credit Risk [Abstract]
Financial Instruments And Concentration Of Credit Risk [Text Block]	Note 11 —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, 2017 , 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 contracts in place as of December 31, 2017 have not been designa ted as accounting hedges and, therefore, changes in fair value are recorded within our Con solidated Statements of Income. The Company has an interest rate swap agreement with a notional amount of $155.3 million and $163.9 million as of December 31, 2017 and 2016 , respectively, to 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 LI BOR rate and pays fixed rate interest payments. The fixed interest rate for the contract is 1.4935%. 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 ra te swap contract and the underlying 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 recorded in other comprehensive income on the accompanying Condensed Consolidated Balance Sheets until earnings are affected by the variability of cash flows . The fair value of the interest rate swap was a $2.0 million asset as o f December 31, 2017 and $0.5 as of December 31, 201 6, which was its effective date. During th e year ended December 31, 2017 , the Company recorded unrealized gains of $1.5 million ($0.9 million net of tax) on the swap in other comprehensive income. Du ring the year ended December 31, 2016 , the Company recorded unrealized gains of $0.5 million ($0.3 million net of tax) on the swap in other comprehensive income. See Note 19 . 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 accou nts 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 res pond accordingly. Management considers these concentrations of credit risks in establishing our allowance for doubtful accounts and believes these allowances are adequate. The Company had two customers whose gross accounts receivable exceeded 10% of total gross accounts receivable as of December 31, 2017 . One customer represented 19 % of our total gross accounts receivable and the second customer represented 11 %.

Restructuring Charges [Abstract]
Restructuring Charges	Note 17 —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 2017 , 2016 and 2015 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 Accoun29

Summary Of Significant Accounting Policies (Policy)	12 Months Ended
	Dec. 31, 2017
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 intercompany balances and transactions have been eliminated in consolidation.
Cash And Cash Equivalents	(c) Cash and Cash Equivalents The Company considers all highly liquid debt instruments wi th an original maturity at the date of purchase of three months or less to be cash equivalents. Cash equivalents of $ 581.4 million and $ 531.8 million at December 31, 2017 and 2016 , respectively, consist ed primarily of money-market funds and time depo sits 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 f inancial 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 li tigation, where appropriate) have been exhausted. During 2017 , the Company recorded a $ 1 .7 million charge for provisions to accounts receivable associated with the insolvency of a customer.
Inventories	(e ) Inventories Inventories include material, labor and overhead and are stated at the lower of cost (principally first-in, first-out method) or market.
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. Leasehold 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 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 amortization , 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 as set 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 liabilities 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, at a minimum, and whenever events and c hanges 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 is 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 goodwill impairment assessments as of December 31, 2017 , 2016 and 2015 , the Company conc luded that goodwill was not impaired.
Earnings Per Share	(i ) Earnings 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 instrume nts, 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 repurchase 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) 2017 2016 2015 Net income (loss) $ (31,965) $ 64,047 $ 95,401 Denominator for basic earnings per share – weighted-average number of common shares outstanding during the period 49,680 49,298 51,573 Incremental common shares attributable to exercise of dilutive options — 313 318 Incremental common shares attributable to outstanding restricted stock units — 214 197 Denominator for diluted earnings per share 49,680 49,825 52,088 Basic earnings (loss) per share $ (0.64) $ 1.30 $ 1.85 Diluted earnings (loss) per share $ (0.64) $ 1.29 $ 1.83 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 million and 1.3 mi llion common shares in 2016 and 2015 , respectively, were not included in the computation of diluted earnings per share because their effect would have been anti-dilutive.
Revenue Recognition	(j ) Revenue Recognition Revenue from the sale of manufact ured products built to customer specifications and excess inventory is recognized when title and risk of ownership have passed, the price to the buyer is fixed or determinable and recoverability is reasonably assured, which generally is when the goods are shipped. Revenue from design, development and engineering services is recognized when the services are performed and collectibility is reasonably certain. Such services provided under fixed price contracts are accounted for using the percentage-of-completi on method. The Company assumes no significant obligations after shipment as it typically warrants workmanship only. Therefore, the warranty provisions are generally not significant.
Income Taxes	( k ) Income Taxes Income taxes are accounted for under the asset and liab ility 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 respective tax bases. Deferred tax assets and liabi lities 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 scheduled 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, are recognized in the financia l statements based on their grant date fair values. The total compensation cost recognized for stock-based awards was $7.8 million, $5.3 million and $7.7 million for 2017 , 2016 and 2015 , respectively. The total income tax benefit r ecognized in the income statement for stock-based awards was $2.8 million, $1 . 1 million and $3.1 million for 2017 , 2016 and 2015 , respectively. The compensation expense for stock-based awards is recognized over the vesting per iod of the awards using the straight-line method. Awards of restricted shares, restricted stock units and performance-based restricted stock units are valued at the closing market price of the Company’s common shares on the date of grant. For performance-b ased 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 expectatio n of performance during the measurement period, that more or less than the previous estimate of the awarded shares will vest, an adjustment to stock-ba sed compensation expense is recognized as a change in accounting estimate. As of December 31, 2017 , 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 $ 535 $ 10,738 $ 3,345 Remaining weighted-average amortization period 0.6 years 2.2 years 1.8 years (1) Based on the probable achievement of the performance goals identified in each award. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. The weighted-average fair value per option granted during 2015 was $8.76. No options were granted during 2017 or 2016 . The weighted-average assumptions used to value the options granted during the year ended December 31, 2015 were as follows: (in thousands) Options granted 289 Expected term of options 6.4 years Expected volatility 35% Risk-free interest rate 1.886% Dividend yield zero The expected term of the options represents the estimated period of time until exercise and is based on historical experience, giving consideration to the contractual terms, vesting schedules and expectations of future plan participant behavior. Separate groups of plan participants that have similar historical exercise behavior are considered separately for valuation purposes. Expected stock price volatility is based on the historical volatility of the Company’s common shares. The risk-free interest rate i s based on the U.S. Treasury zero-coupon rates in effect at the time of grant with an equivalent remaining term. The dividend yield reflects that the Company has not paid any cash dividends since inception and does not anticipate paying cash dividends in t he foreseeable future . The total cash received as a result of stock option exercises in 2017 , 2016 and 2015 was approximately $11.2 million, $18.8 million and $2.0 million, respectively. The actual tax benefit realized as a result of stock option exercises and the vesting of other share-based awards during 2017 , 2016 and 2015 was $5.0 million, $3.7 million and $2.1 million, respectively. For 2017 , 2016 and 2015 , the total intrinsic value of stock options exercised was $7.7 million, $5.1 million and $0.7 million, respectively. The Company awarded performance-based restricted stock units to employees during 2017 , 2016 and 2015 . The number of performan ce-based restricted 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 o f certain performance 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 financial 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 an d will be forfeited. 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 ma de a number of estimates 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 evaluat es 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 Inst ruments 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 drive rs 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. The 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 approximate their fair value. As of December 31, 2017 , all of the Company’s long-term investments and derivative instruments were recorded at f air value using Level 3 inputs. See Note 11 .
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 translati on adjustments are reported in 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 $ 2.1 million, $ 0.5 million and $ 2.3 million in 2017 , 2016 and 2015 , 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 recorde d on the balance sheet at fair 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 de rivative instrument is designated 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 hedg ed item affects earnings. Changes 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.
Recently Enacted Accounting Principles	(q) New Accounting Pronouncements Adopted in 2017 Effective January 1, 2017, the Company adopted a new accounting standard s update that simplifies several aspects of the accounting for employee share-based payment transactions, including accounting for income taxes, forfeitures, and statutory withholding requirements, as well as classification in the Consolidated Statements of Cash Flows. As required by this standard, excess tax benefits recognized on stock-based compensation expense are reflected in the accompanying Consolidated Income Statement as a component of the provision for income taxes on a prospective basis (See Note 9 ). As a result of including the income tax effects from excess tax benefits in income tax expense, the effects of the excess tax benefits are no longer included in the calculation of diluted shares outstanding, resulting in an increase in the number of diluted shares outstanding. The Company adopted this change in the method of calculating diluted shares outstanding on a prospective basis. Additionally, excess tax benefits or deficiencies recognized on stock-based compensation expense are classified as an operating activit y in the accompanying Consolidated Statements of Cash Flows. The Company has applied this provision prospectively. Additionally, the Company is now required to present the cost of shares withheld from the employee to satisfy the empl oyees’ income tax liability as a financing activity on the statement of cash flows rather than as an operating cash flow. The Company adopted this change r etrospectively. As a result, in both of the years ended December 31, 2016 and 2015 , net cash pr ovided by operations increased by $0.6 million with a corresponding offset to net cash used in financing activities. The standard also allows for the option to account for forfeitures as they occur when determining the amount of compensation cost to be rec ognized, rather than estimating expected forfeitures over the course of a vesting period. The Company elected to account for forfeitures as they occur. The net cumulative effect to the Company from the adoption of this accounting standard update was an inc rease to paid-in capital of $0.2 million and a reduction to retained earnings of $0.2 million. Effective January 1, 2017 , the Company adopted an accounting standards update which applies to inventory that is measured using first-in, first-out or average c ost, with new guidance on simplifying the measurement of inventory. Inventory within the scope of this update is required to be measured at the lower of its cost or net realizable value, with net realizable value being the estimated selling price in the or dinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The adoption of this update by the Company did not have a material impact on the Company’s consolidated financial statements . 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. This up date is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017, with early adoption permitted. The Company is evaluating the impact of the adoption of this guidance on its consolidated financial sta tements and related disclosures but does not expect it to have a material impact. The Company adopted the new guidance effective January 1, 2018. In August 2016, the FASB issued a new accounting standards update, which seeks to reduce the existing diversi ty 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. In May 2014, the FASB issued a new standard (commonly referred to as ASC 606) , wh ich will change the way the Company recognizes revenue and significantly expands the disclosure requirements for revenue arrangements. The new standard is effective for annual reporting periods beginning after December 15, 2017. The Company adopted the re quirements of the new standard on January 1, 2018 using the full retrospective transition method . We will adjust prior period consolidated financial statements to reflect full retrospective adoption beginning with the Quarterly Report on Form 10-Q for the first quarter of 2018. As ASC 606 supersedes substantially all existing revenue guidance affecting the Company under current U.S. GAAP, it will impact revenue and cost recognition across its business, as well as its business processes. The Company has subs tantially completed the implementation of changes to internal controls over financial reporting to allow the Company to timely compile the information needed to account for transactions under this new guidance and to adjust its prior periods’ consolidated financial statements . Under ASC 606, revenue will be recognized as or when the customer obtains control of the goods or services promised in the contract. Given the nature of the terms and conditions in substantially all of the Company’s customer contract s, the customer obtains control as the Company per forms work under the contract. For these contracts, the Company expects t o recognize revenue over time. Revenue for all other goods will be recognized at a point in time, upon transfer of control of the pro duct to the customer (i.e., effectively no change to current accounting). The Company currentl y recognizes the majority of its manufacturing revenue when title and risk of ownership have passed, the price to the buyer is fixed or determinable and recovera bility is reasonably assured, which generally is when the goods are shipped. Under ASC 606, the Company will recognize revenue over time for a significant majority of its manufacturing contracts. This will change the timing of revenue recognition for a sig nificant portion of the Company’s business, whereby revenue will be recognized earlier than under the current accounting rules. ASC 606 will also have material impacts to the Company’s balance sheet, primarily related to a reduction in finished goods and w ork-in-process inventories and an increase in contract assets . The Company has completed its preliminary assessment of adopting ASC 606 on the Company’s 2017 and 2016 operating results, which will reduce diluted earnings per share by approximately $ 0.02 f or 2017 and increase diluted earnings per share by approximately $ 0.02 for 2016. The impact of adopting ASC 606 on the Company’s 2017 and 2016 operating results may not be indicative of the adoption imp acts in future periods or of its operating performance . Total net cash provided by operating activities and net cash used by investing and financing activities on its consolidated statements of cash flows will not be impacted by the adoption of ASC 606 . Not Yet Adopted In February 2018, the FASB issued new accounting guidance on the reclassification of certain tax effects from accumulated other comprehensive income to retained earnings. This optional guidance is effective January 1, 2019, with early adoption permitted. The Company is eval uating whether it wi ll adopt this new guidance along with any impacts on the Company’s financial position, results of operations and cash flows, none of which are expected 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 annua l 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. In February 2016, the FASB issued a new accounting standards update changing the accounting for leases and including a requirement to record all leases on the consolidated balance sheets as assets and liabilities. This update is effective for fiscal years beginning after December 15, 2018. The Company will adopt this update effective January 1, 2019, which will impact its consolidated balance sheet. The Company is currently evaluating the impact this standard will have on its consolidated financial statements. The Company has determined tha t all other recently issued accounting standards will not have a material impact on its consolidated financial position, results of operations and cash flows, or do not apply to its operations.

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 two customers whose gross accounts receivable exceeded 10% of total gross accounts receivable as of December 31, 2017. One customer represented 19% of our total gross accounts receivable and the second customer represented 11%.
