Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	NOTE A – BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements of Preformed Line Products Company and subsidiaries (the “Company” or “PLPC”) have been prepared in accordance with United States of America (U.S.) generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. The preparation of these consolidated financial statements requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and the accompanying notes. Actual results could differ from these estimates. In the opinion of management, these consolidated financial statements contain all estimates and adjustments, consisting of normal recurring accruals, required to fairly present the financial position, results of operations, and cash flows for the interim periods. Operating results for the three and nine months ended September 30, 2017 are not necessarily indicative of the results to be expected for the full-year ending December 31, 2017. The Consolidated Balance Sheet at December 31, 2016 has been derived from the audited consolidated financial statements, but does not include all of the information and notes required by U.S. GAAP for complete financial statements. For further information, refer to the consolidated financial statements and notes to consolidated financial statements included in the Company’s 2016 Annual Report on Form 10-K filed on March 10, 2017 with the Securities and Exchange Commission.

Other Financial Statement Information	NOTE B – OTHER FINANCIAL STATEMENT INFORMATION Inventories – net September 30, 2017 December 31, 2016 Raw materials $ 41,354 $ 37,535 Work-in-process 9,781 9,057 Finished Goods 32,889 35,629 84,024 82,221 Excess of current cost over LIFO cost (2,964 ) (2,784 ) Noncurrent portion of inventory (5,385 ) (4,953 ) $ 75,675 $ 74,484 Cost of inventories for certain material is determined using the last-in-first-out (LIFO) method and totaled approximately $26.2 million at September 30, 2017 and $28.6 million at December 31, 2016. An actual valuation of inventories under the LIFO method can be made only at the end of the year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations are based on management’s estimates of expected year-end inventory levels and costs. Because these estimates are subject to change and may be different than the actual inventory levels and costs at the end of the year, interim results are subject to the final year-end LIFO inventory valuation. During the three and nine-month periods ended September 30, 2017, the net change in LIFO inventories resulted in $.1 million of expense and $.2 million of expense, respectively, to Income before income taxes. During the three and nine months ended September 30, 2016, the net change in LIFO inventories resulted in a $.2 million and $.3 million benefit to Income before income taxes, respectively. Noncurrent inventory is included in Other assets on the Consolidated Balance Sheets. Property, plant and equipment—net Major classes of Property, plant and equipment are stated at cost and were as follows: September 30, 2017 December 31, 2016 Land and improvements $ 13,287 $ 12,584 Buildings and improvements 75,652 72,662 Machinery, equipment and aircraft 169,916 158,078 Construction in progress 4,020 3,877 262,875 247,201 Less accumulated depreciation 154,568 142,097 $ 108,307 $ 105,104 Legal proceedings The Company and its subsidiaries Helix Uniformed Ltd. (“Helix”) and Preformed Line Products (Canada) Limited (“PLPC Canada”), were each named, jointly and severally, with each of SNC-Lavalin ATP, Inc. (“SNC ATP”), HD Supply Canada Inc., by its trade names HD Supply Power Solutions and HD Supply Utilities (“HD Supply”), and Anixter Power Solutions Canada Inc. (the corporate successor to HD Supply, “Anixter” and, together with the Company, PLPC Canada, Helix, SNC ATP and HD Supply, the “Defendants”) in a complaint filed by Altalink, L.P. (the “Plaintiff”) in the Court of Queen’s Bench of Alberta in Alberta, Canada in November 2016 (the “Complaint”). The Complaint states that Plaintiff engaged SNC ATP to design, engineer, procure and construct numerous power distribution and transmission facilities in Alberta (the “Projects”) and that through SNC ATP and HD Supply (now Anixter), spacer dampers manufactured by Helix were procured and installed in the Projects. The Complaint alleges that the spacer dampers have and may continue to become loose, open and detach from the conductors, resulting in damage and potential injury and a failure to perform the intended function of providing spacing and damping to the Project. The Plaintiffs are seeking an estimated $56 million in damages jointly and severally from the Defendants, representing the costs of monitoring and replacing the spacer dampers and remediating property damage, due to alleged defects in the design and construction of, and supply of materials for, the Projects by SNC ATP and HD Supply/Anixter and in the design of the spacer dampers by Helix. The lawsuit is in its very early stages, but the Company believes the claims against it are without merit and intends to vigorously defend against such claims. However, the Company is unable to predict the outcome of this case and, if determined adversely to the Company, it could have a material effect on the Company’s financial results. The Company is not a party to any other pending legal proceedings that the Company believes would, individually or in the aggregate, have a material adverse effect on its financial condition, results of operations or cash flows.

Earnings Per Share [Abstract]
Computation of Earnings Per Share	NOTE E – COMPUTATION OF EARNINGS PER SHARE Basic earnings per share were computed by dividing Net income by the weighted-average number of common shares outstanding for each respective period. Diluted earnings per share were calculated by dividing Net income by the weighted-average of all potentially dilutive common stock that was outstanding during the periods presented. The calculation of basic and diluted earnings per share for the three and nine months ended September 30, 2017 and 2016 was as follows: Three Months Ended September 30 Nine Months Ended September 30 2017 2016 2017 2016 Numerator Net income $ 6,278 $ 4,742 $ 11,952 $ 10,154 Denominator Determination of shares Weighted-average common shares outstanding 5,104 5,146 5,113 5,180 Dilutive effect - share-based awards 16 23 16 20 Diluted weighted-average common shares outstanding 5,120 5,169 5,129 5,200 Earnings per common share Basic $ 1.23 $ 0.92 $ 2.34 $ 1.96 Diluted $ 1.23 $ 0.92 $ 2.33 $ 1.95 For the three and nine-month periods ended September 30, 2017, 27,000 and 35,584 stock options, respectively, were excluded from the calculation of diluted earnings per share as the effect would have been anti-dilutive. For the three and nine-month periods ended September 30, 2016, 47,850 and 55,350, respectively, stock options were excluded from the calculation of diluted earnings per share as the effect would have been anti-dilutive.

Goodwill And Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangibles	Note F – GOODWILL AND OTHER INTANGIBLES The Company’s finite and indefinite-lived intangible assets consist of the following: September 30, 2017 December 31, 2016 Gross Carrying Amount Accumulated Amortization Gross Carrying Amount Accumulated Amortization Finite-lived intangible assets Patents $ 4,808 $ (4,791 ) $ 4,816 $ (4,799 ) Land use rights 1,173 (199 ) 1,070 (180 ) Trademarks 1,798 (1,146 ) 1,725 (1,039 ) Technology 3,211 (1,201 ) 3,057 (1,031 ) Customer relationships 12,525 (5,774 ) 12,073 (5,217 ) $ 23,515 $ (13,111 ) $ 22,741 $ (12,266 ) Indefinite-lived intangible assets Goodwill $ 16,689 $ 15,769 The aggregate amortization expense for other intangibles with finite lives for the three and nine months ended September 30, 2017 was $.3 million and $.8 million, respectively. The aggregate amortization expense for other intangibles with finite lives for each of the three and nine months ended September 30, 2016 was $.3 million and $.8 million, respectively. Amortization expense is estimated to be $.3 million for the remaining period of 2017, $1.0 million annually for 2018 and 2019, and $.9 million for both 2020 and 2021. The weighted-average remaining amortization period is approximately 16.7 years. The weighted-average remaining amortization period by intangible asset class is as follows: patents, 8.3 years; land use rights, 58.3 years; trademarks, 9.3 years; technology, 14.2 years; and customer relationships, 12.5 years. The Company’s measurement date for its annual impairment test for goodwill is October 1st of each year. The Company performs its annual impairment test for goodwill utilizing a discounted cash flow methodology, market comparables, and an overall market capitalization reasonableness test in computing fair value by reporting unit. The Company then compares the fair value of the reporting unit with its carrying value to assess if goodwill has been impaired. Based on the assumptions as to growth, discount rates and the weighting used for each respective valuation methodology, results of the valuations could be significantly different. However, the Company believes that the methodologies and weightings used are reasonable and result in appropriate fair values of the reporting units. The Company’s valuation method uses Level 3 inputs under the fair value hierarchy. The Company’s only intangible asset with an indefinite life is goodwill. The changes in the carrying amount of goodwill, by segment, for the nine months ended September 30, 2017 are as follows: USA The Americas EMEA Asia-Pacific Total Balance at January 1, 2017 $ 3,078 $ 4,017 $ 1,287 $ 7,387 $ 15,769 Currency translation 0 364 129 427 920 Balance at September 30, 2017 $ 3,078 $ 4,381 $ 1,416 $ 7,814 $ 16,689

Long Term Incentive Plan of 2008 and 2016 Incentive Plan The Company maintains an equity award program to give the Company a competitive advantage in attracting, retaining, and motivating officers, employees and directors and to provide an incentive to those individuals to increase shareholder value through long-term incentives directly linked to the Company’s performance. Under the Preformed Line Products Company Long Term Incentive Plan of 2008 (the “LTIP”), certain employees, officers, and directors were eligible to receive awards of options, restricted shares and restricted share units (RSUs). The total number of Company common shares reserved for awards under the LTIP was 900,000, of which 800,000 common shares were reserved for RSUs and 100,000 common shares have been reserved for share options. The LTIP was terminated and replaced with the Preformed Line Products Company 2016 Incentive Plan (the “Incentive Plan”) in May 2016 upon approval by the Company’s Shareholders at the 2016 Annual Meeting of Shareholders on May 10, 2016. No further awards will be made under the LTIP and previously granted awards remain outstanding in accordance with their terms. Under the Incentive Plan, certain employees, officers, and directors will be eligible to receive awards of options, restricted shares and RSUs. The total number of Company common shares reserved for awards under the Incentive Plan is 1,000,000 of which 900,000 common shares have been reserved for restricted share awards and 100,000 common shares have been reserved for share options. The Incentive Plan expires on May 10, 2026. Restricted Share Units For the regular annual grants, a portion of the RSUs is subject to time-based cliff vesting and a portion is subject to vesting based upon the Company’s performance over a set period for all participants except the CEO. All of the CEO’s regular annual RSUs are subject to vesting based upon the Company’s performance over a set-year period. The RSUs are offered at no cost to the employees. The fair value of RSUs is based on the market price of a common share on the grant date and the shares are restricted until they vest. The portion of the RSU’s granted to the Company’s former Chief Financial Officer in 2015, 2016 and 2017 that had not yet vested as of his retirement date of May 31, 2017 were forfeited. Dividends declared are accrued in cash. A summary of the RSUs outstanding under the LTIP for the nine months ended September 30, 2017 is as follows: Restricted Share Units Performance and Service Required (1) Service Required Total Restricted Share Units Weighted-Average Grant-Date Fair Value Nonvested as of January 1, 2017 130,168 15,974 146,142 $ 38.46 Granted 80,247 10,560 90,807 54.60 Vested 0 0 0 0.00 Forfeited (9,843 ) (2,461 ) (12,304 ) 46.86 Nonvested as of September 30, 2017 200,572 24,073 224,645 $ 44.53 (1) Nonvested performance-based RSUs are reflected at the maximum performance achievement level. For time-based RSUs, the Company recognizes stock-based compensation expense on a straight-line basis over the requisite service period of the award in General and administrative expense in the accompanying Statements of Consolidated Income. For the performance-based RSUs, the number of RSUs in which the participants will vest depends on the Company’s level of performance measured by growth in either operating or pre-tax income and sales growth over a requisite performance period. Depending on the extent to which the performance criterions are satisfied under the LTIP, the participants are eligible to earn common shares over the vesting period. Performance-based compensation expense for the three and nine months ended September 30, 2017 was $.9 million and $1.8 million, respectively. Performance-based compensation expense for the three and nine months ended September 30, 2016 was $.3 million and $.6 million, respectively. As of September 30, 2017, the remaining compensation expense of $4.2 million for outstanding performance-based RSU’s is expected to be recognized over a period of approximately 2.0 years. In the event of a Change in Control (as defined in the LTIP), vesting of the RSUs will be accelerated and all restrictions will lapse. Unvested performance-based awards are based on a target potential payout. Actual shares awarded at the end of the performance period may be less than the target potential payout level depending on achievement of performance-based award objectives. To satisfy the vesting of its RSU awards, the Company has reserved new shares from its authorized but unissued shares. Any additional awards granted will also be issued from the Company’s authorized but unissued shares. Share Option Awards The LTIP permitted and now the Incentive Plan permits the grant of 100,000 options to buy common shares of the Company to certain employees at not less than fair market value of the shares on the date of grant. Options issued to date under the LTIP vest 50% after one year following the date of the grant, 75% after two years, and 100% after three years, and expire from five to ten years from the date of grant. Shares issued as a result of stock option exercises will be funded with the issuance of new shares. The Company utilizes the Black-Scholes option pricing model for estimating fair values of options. The Black-Scholes model requires assumptions regarding the volatility of the Company’s stock, the expected life of the stock award and the Company’s dividend yield. The Company utilizes historical data in determining these assumptions. The risk-free rate for periods within the contractual life of the option is based on the U.S. zero coupon Treasury yield in effect at the time of grant. There were 5,000 options granted for the nine months ended September 30, 2017 and 1,000 options granted for the nine months ended September 30, 2016. Stock option activity under the Company’s LTIP for nine months ended September 30, 2017 was as follows: Number of Shares Weighted Average Exercise Price per Share Weighted Average Remaining Contractual Term (Years) Aggregate Intrinsic Value (000's) Outstanding at January 1, 2017 52,750 $ 54.54 Granted 5,000 $ 48.00 Exercised 0 $ 0.00 Forfeited 0 $ 0.00 Outstanding (vested and expected to vest) at September 30, 2017 57,750 $ 53.98 6.8 $ 821 Exercisable at September 30, 2017 44,625 $ 56.34 6.2 $ 541 There were 0 and 1,000 stock options exercised during the nine months ended September 30, 2017 or 2016, respectively. The total intrinsic value of stock options exercised during the nine months ended September 30, 2016 was less than $.1 million. Cash received for the exercise of stock options during the nine months ended September 30, 2016 was less than $.1 million. For the three and nine-month periods ended September 30, 2017, the Company recorded compensation expense related to the stock options currently vested of less than $.1 million and $.1 million, respectively. For the three and nine months ended September 30, 2016, the Company recorded compensation expense related to the stock options currently vested of less than $.1 million and $.1 million, respectively. The total compensation cost related to nonvested awards not yet recognized at September 30, 2017 is expected to be $.1 million over a weighted-average period of approximately 1.9 years. Deferred Compensation Plan The Company maintains a trust, commonly referred to as a rabbi trust, in connection with the Company’s deferred compensation plan. This plan allows for two deferrals. First, Directors make elective deferrals of Director fees payable and held in the rabbi trust. The deferred compensation plan allows the Directors to elect to receive Director fees in common shares of the Company at a later date instead of fees paid each quarter in cash. Second, this plan allows certain Company employees to defer restricted shares or RSUs for future distribution in the form of common shares. Assets of the rabbi trust are consolidated, and the value of the Company’s common shares held in the rabbi trust is classified in Shareholders’ equity and generally accounted for in a manner similar to treasury stock. The Company recognizes the original amount of the deferred compensation (fair value of the deferred stock award at the date of grant) as the basis for recognition in common shares issued to the rabbi trust. Changes in the fair value of amounts owed to certain employees or Directors are not recognized as the Company’s deferred compensation plan does not permit diversification and must be settled by the delivery of a fixed number of the Company’s common shares. As of September 30, 2017, 298,160 shares have been deferred and are being held in the rabbi trust.

Fair Value Disclosures [Abstract]
Fair Value of Financial Assets and Liabilities	NOTE H – FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES The carrying value of the Company’s current financial instruments, which include cash and cash equivalents, accounts receivable, accounts payable, notes payable, and short-term debt, approximates its fair value because of the short-term maturity of these instruments. At September 30, 2017, the fair value of the Company’s long-term debt was estimated using discounted cash flow analysis based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements which are considered to be Level 2 inputs. There have been no transfers in or out of Level 2 for the nine months ended September 30, 2017. Based on the analysis performed, the carrying value of the Company’s long-term debt approximates fair value at September 30, 2017 and December 31, 2016.

Accounting Changes And Error Corrections [Abstract]
Recently Adopted Accounting Pronouncements	NOTE I – RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update “ASU 2016-09”, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” ASU 2016-09 amends several aspects of the accounting for share-based payment transactions including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The Company adopted ASU 2016-09 effective January 1, 2017. ASU 2016-09 requires prospective recognition of excess tax benefits and deficiencies resulting from stock-based compensation awards vesting and exercises to be recognized as a discrete income tax adjustment in the income statement. Previously, these amounts were recognized in Paid in capital. The Company had $0 excess tax benefit recorded during the nine months ended September 30, 2017. In addition, ASU 2016-09 requires excess tax benefits and deficiencies to be prospectively excluded from the assumed future proceeds in the calculation of diluted shares, resulting in an insignificant increase in diluted weighted average number of shares outstanding for the nine months ended September 30, 2017 and an immaterial impact on earnings per share. ASU 2016-09 requires that excess tax benefits from share-based compensation awards be reported as operating activities in the Statements of Consolidated Cash Flows. Previously, this activity was included in financing activities on the Statements of Consolidated Cash Flows. As permitted, the Company has elected to apply this change prospectively. ASU 2016-09 requires that employee taxes paid when an employer withholds shares for tax withholding purposes be reported as financing activities in the Statements of Consolidated Cash Flows on a retrospective basis. Previously, this activity was included in financing activities and, therefore, this resulted in no impact to the Statements of Consolidated Cash Flows. The Company has elected to account for forfeitures as they occur to estimate the number of stock-based awards expected to vest as permitted by ASU 2016-09. In July 2015, the FASB issued Accounting Standards Update 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory.” The amendments in this Update more closely align the measurement of inventory in GAAP with the measurement of inventory in International Financial Reporting Standards (IFRS). The Company adopted ASU 2015-11 effective January 1, 2017. Under ASU 2015-11, an entity should measure inventory within the scope of this Update at the lower of cost and net realizable value. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Subsequent measurement is unchanged for inventory measured using LIFO or the retail inventory method. The amendments in this Update are effective for fiscal years beginning after December 15, 2016 including interim periods within those fiscal years. The amendments in this Update have been applied prospectively and did not have an effect on Company’s consolidated financial statements for the three and nine months ended September 30, 2017.

New Accounting Standards to be

New Accounting Standards to be Adopted	9 Months Ended
	Sep. 30, 2017
Accounting Changes And Error Corrections [Abstract]
New Accounting Standards to be Adopted	NOTE J – NEW ACCOUNTING STANDARDS TO BE ADOPTED In March 2017, the FASB issued ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost,” which requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. The guidance is effective for fiscal years beginning after December 15, 2017. Early adoption is permitted for any entity in any interim or annual period. If an entity early adopts the amendment in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period as well as the nature and reason for the change in accounting principle. The Company is currently evaluating what impact, if any, its adoption will have to the presentation of the Company’s consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment,” to eliminate Step 2 from the goodwill impairment test in order to simplify the subsequent measurement of goodwill. The guidance is effective for fiscal years beginning after December 15, 2019. Early application is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. Adoption of this guidance is not expected to have a material impact on the Company’s Consolidated Financial Statements. In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash.” The amendments in this Update require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. This ASU is effective for annual reporting periods beginning after December 15, 2017, including interim periods within the annual reporting period. Early adoption is permitted for any entity in any interim or annual period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The amendments in this Update should be applied using a retrospective transition method to each period presented. The Company is currently evaluating what impact, if any, its adoption will have to the presentation of the Company’s consolidated financial statements. In October 2016, the FASB issued ASU 2016-16, “Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory.” ASU 2016-16 modifies the recognition of income tax expense resulting from intra-entity transfers of assets other than inventory. Pursuant to this amendment, entities should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. This amendment eliminates the exception for an intra-entity transfer of assets other than inventory. This ASU is effective for annual reporting periods beginning after December 15, 2017, including interim periods within the annual reporting period. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” The amendments in this Update require the recognition of assets and liabilities arising from lease transactions on the balance sheet and the disclosure of key information about leasing arrangements. Accordingly, a lessee will recognize a lease asset for its right to use the underlying asset and a lease liability for the corresponding lease obligation. Both the asset and liability will initially be measured at the present value of the future minimum lease payments over the lease term. Subsequent measurement, including the presentation of expenses and cash flows, will depend on the classification of the lease as either a finance or an operating lease. Initial costs directly attributable to negotiating and arranging the lease will be included in the asset. For leases with a term of 12 months or less, a lessee can make an accounting policy election by class of underlying asset to not recognize an asset and corresponding liability. Lessees will also be required to provide additional qualitative and quantitative disclosures regarding the amount, timing and uncertainty of cash flows arising from leases. These disclosures are intended to supplement the amounts recorded in the financial statements and provide additional information about the nature of an organization’s leasing activities. The amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating what impact, if any, its adoption will have to the presentation of the Company’s consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” or ASU 2014-09. ASU 2014-09 requires an entity to recognize revenue in a matter that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, the amendment provides five steps that an entity should apply when recognizing revenue. The amendment also specifies the accounting of some costs to obtain or fulfill a contract with a customer and expands the disclosure requirements around contracts with customers. An entity can either adopt this amendment retrospectively to each prior reporting period presented or retrospectively with cumulative effect of initially applying the update recognized at the date of initial application. In August 2015, the FASB issued ASU No. 2015-14 deferring the effective date of the amendment to annual reporting periods beginning after December 15, 2017, including interim periods therein. Although early adoption is permitted, the Company plans to adopt the new guidance effective January 1, 2018 and has developed and is executing on an implementation plan to meet this adoption date. The Company has established a transition team to analyze the impact of the standard on our revenue contracts, which has included scoping our revenue streams in order to compare historical accounting policies and practices to the new revenue standards. The Company’s analysis is ongoing with respect to whether certain contracts will be recognized over time or at a point in time. Additionally, the Company is in the process of identifying and assessing appropriate changes to our business processes, systems and controls to support revenue recognition and disclosures under the new standard. The Company will continue to update the assessment of the impact of ASU 2014-09 and related impacts to the Company’s consolidated financial statements and will disclose material impacts, if any.

Income Taxes	NOTE L – INCOME TAXES The Company’s effective tax rate was 36% and 27% for the three months ended September 30, 2017 and 2016, respectively, and 34% and 27% for the nine months ended September 30, 2017 and 2016, respectively. The higher effective tax rate for the three months ended September 30, 2017, compared to the U.S. federal statutory tax rate of 35%, was primarily due to U.S permanent items, predominantly related to the repatriation of foreign earnings that are not permanently reinvested, offset by an increase in earnings in jurisdictions with tax rates lower than the U.S. federal statutory tax rate where such earnings are reinvested. The lower effective tax rate for the nine months ended September 30, 2017 compared to the U.S federal statutory tax rate of 35% was primarily due to an increase in earnings in jurisdictions with lower tax rates than the U.S. federal statutory rate where such earnings are permanently reinvested and offset by U.S. permanent items primarily related to the repatriation of foreign earnings that are not permanently reinvested. The higher tax rate for the three and nine months ended September 30, 2017, compared with the same periods for 2016, was primarily due to the repatriation of foreign earnings that are not permanently reinvested. As described in Note I, effective January 1, 2017, the Company adopted the new guidance (ASU 2016-09) and will record excess tax benefits or tax deficiencies from stock-based compensation in the Statements of Consolidated Income within the provision for income taxes rather than in the Consolidated Balance Sheets within Paid-in capital. The related financial statement impacts of adopting ASU 2016-09 have not been material to the Company’s Consolidated Financial Statements. The Company provides valuation allowances against deferred tax assets when it is more likely than not that a portion or all of its deferred tax assets will not be realized. During the nine months ended September 30, 2017, the Company recorded a $.2 million valuation allowance as a discrete item against a deferred tax asset resulting from a capital loss carry forward generated in 2016. During the period ended September 30, 2017, the Company did not record any unrecognized tax benefits and as of September 30, 2017, the Company has no unrecognized tax benefits. The Company does not anticipate any significant changes to its gross unrecognized tax benefits within the next twelve months.

Restructuring And Related Activities [Abstract]
Charges Related to Restructuring Activities	NOTE N – CHARGES RELATED TO RESTRUCTURING ACTIVITIES The Company previously reconfigured one of its operations within its Asia Pacific segment by reducing its workforce and manufacturing facilities while outsourcing production predominantly to its locations with lower cost operations. This was done in response to a slowdown in economic activity in the region as well as continued downward market pressure on prices. These actions reduced go-forward infrastructure and manufacturing costs. No expense was recognized in the nine months ended September 30, 2017 and expense of $.1 million was recognized in the nine months ended September 30, 2016 for these restructuring activities. The restructuring liability remaining at September 30, 2017 A summary of the accruals recorded as a result of the restructuring is as follows: Lease Termination Severance Costs Other Total December 31, 2016 Balance $ 0 $ 478 $ 0 $ 478 Charges 0 0 0 0 Payments and other adjustments 0 (48 ) 32 (16 ) September 30, 2017 Balance $ 0 $ 430 $ 32 $ 462
