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, 2014 are not necessarily indicative of the results to be expected for the full year ending December 31, 2014.
	The Consolidated Balance Sheet at December 31, 2013 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 2013 Annual Report on Form 10-K filed on March 14, 2014 with the Securities and Exchange Commission.

	Noncurrent portion of inventory		(7,034	)		(7,350	)
		$	79,415		$	73,835
	Cost of inventories for certain material is determined using the last-in-first-out (LIFO) method and totaled approximately $25.5 million at September 30, 2014 and $25.1 million at December 31, 2013. 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 must be 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 months ended September 30, 2014, the net change in LIFO inventories resulted in a $.2 million and $.1 million charge to Income before income taxes, respectively. During the three and nine months ended September 30, 2013, the net change in LIFO inventories resulted in a $.1 million benefit to and a $.2 million charge to Income before income taxes, respectively.
	Noncurrent inventory is included in Other assets on the Consolidated Balance Sheets.

Computation of Earnings Per Share	'
	NOTE E – COMPUTATION OF EARNINGS PER SHARE
	Basic earnings per share was 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, 2014 and 2013 was as follows:
		Three Months Ended				Nine Months Ended
		September 30				September 30

	For the three and nine months ended September 30, 2014, 25,750 and 20,750 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 months ended September 30, 2013, 22,500 and 17,750 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 months ended September 30, 2014, 51,425 and 49,967 restricted share units, respectively, were excluded from the calculation of diluted earnings per share as the effect of the exercise would have been anti-dilutive. For the three and nine months ended September 30, 2013, no restricted shares were excluded from the calculation of diluted earnings per share as the effect of the exercise would not have been anti-dilutive.

	Indefinite-lived intangible assets
	Goodwill	$	18,359					$	13,873
	The aggregate amortization expense for other intangibles with finite lives for the three and nine months ended September 30, 2014 and 2013 was $.4 million and $1.2 million, respectively. Amortization expense is estimated to be $.4 million for the remaining period of 2014, $1.3 million for 2015, $1.2 million for 2016, $1.1 million for 2017 and $1.1 million for 2018. The weighted-average remaining amortization period by intangible asset class is as follows: patents, 2 years; land use rights, 61.9 years; trademark, 11 years; technology, 17.1 years; and customer relationships, 15.4 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.
	During the third quarter of 2014, the Company experienced softening in the demand for the products sold by one of its locations in the Asia-Pacific region. This was identified as an interim indicator of impairment. As such, the Company performed an interim goodwill impairment assessment of this location. The result of this interim assessment was the Company passed step one by a margin of 7%, which compares to a margin of 41% at October 1, 2013. The Company had a goodwill balance of $3.5 million for this location at September 30, 2014. The Company also assessed whether there was any impairment of its other long-lived assets of this location and determined there was no impairment. The Company had a balance of $3.6 million for its intangible assets of this location at September 30, 2014. The Company will continue to monitor the results of this operation.
	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, 2014, are as follows:
		The Americas			EMEA			Asia-Pacific			Total
	Balance at January 1, 2014	$	3,078		$	1,754		$	9,041		$	13,873
	Additions		4,976			0			0			4,976

	Balance at September 30, 2014	$	8,015		$	1,615		$	8,729		$	18,359
	The additions to goodwill relate to the acquisition of Helix Uniformed Limited on January 31, 2014.

	Forfeited		0		$	0
	Outstanding (exercisable and vested) at September 30, 2014		12,000		$	41.44		3.1	$	136
	There were 1,000 and 12,400 stock options exercised during the nine months ended September 30, 2014 and 2013, respectively. The total intrinsic value of stock options exercised during the nine months ended September 30, 2014 and 2013 was less than $.1 million and $.3 million, respectively. Cash received for the exercise of stock options during the nine months ended September 30, 2014 and 2013 was less than $.1 million and $.5 million, respectively. Excess tax benefits from share-based awards for the nine months ended September 30, 2014 and 2013 were $0 and $.1 million, respectively.
	For the nine months ended September 30, 2014 and 2013, the Company recorded no compensation expense related to stock options for either period as all options are fully vested.
	Long Term Incentive Plan of 2008
	Under the Preformed Line Products Company Long Term Incentive Plan of 2008 (the “LTIP”), certain employees, officers, and directors are eligible to receive awards of options, restricted shares and restricted share units. The purpose of this LTIP is 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. The total number of Company common shares reserved for awards under the LTIP is 900,000. Of the 900,000 common shares, 800,000 common shares have been reserved for restricted share units and 100,000 common shares have been reserved for stock options. The LTIP expires on April 17, 2018.
	Restricted Share Units
	For all of the participants except the CEO, a portion of the restricted share units (RSUs) is subject to time-based cliff vesting and a portion is subject to vesting based upon the Company’s performance over a three-year period. All of the CEO’s RSUs are subject to vesting based upon the Company’s performance over a three-year period.
	The RSUs are offered at no cost to the employees; however, the participant must remain employed with the Company until the restrictions on the RSUs lapse. The fair value of RSUs is based on the market price of a common share on the grant date. The Company currently estimates that no RSUs will be forfeited. Dividends declared are accrued in cash.
	A summary of the RSUs for the nine months ended September 30, 2014 is as follows:
		Restricted Share Units
		Performance			Service		Total		Weighted-Average
		and Service			Required		Restricted		Grant-Date
		Required					Share Units		Fair Value
	Nonvested as of January 1, 2014		89,459			10,202		99,661	$	65.86
	Granted		40,676			4,799		45,475		63.95
	Vested		0			0		0		0
	Forfeited		0			0		0		0
	Nonvested as of September 30, 2014		130,135			15,001		145,136	$	65.26
	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. Compensation expense related to the time-based RSUs for the three and nine months ended September 30, 2014 and 2013 was $.1 million and $.2 million, respectively. As of September 30, 2014, there was $.4 million of total unrecognized compensation cost related to time-based RSUs that is expected to be recognized over the weighted-average remaining period of approximately 1.7 years.
	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 pretax income and sales growth over a requisite performance period. Depending on the extent to which the performance criterions are probable of being 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, 2014 was a less than $.1 million reduction to compensation expense and $.4 million compensation expense, respectively. During the three and nine months ended September 30, 2014, a $.4 million reduction in performance-based compensation expense was recorded related to the 2012 performance-based RSU grant, due to changes in estimates for growth in pretax income. During the three and nine months ended September 30, 2014, a $.2 million and $1.1 million reduction in performance-based compensation expense was recorded related to the 2013 performance-based RSU grant, due to changes in estimates for growth in pretax income. Performance-based compensation expense for the three and nine months ended September 30, 2013 was $.7 million and $.2 million, respectively. As of September 30, 2014, the remaining performance-based RSUs compensation expense of $2.7 million is expected to be recognized over a period of approximately 1.9 years.
	The excess tax benefits from RSUs for the nine months ended September 30, 2014 and 2013 was $.2 million and $0, respectively.
	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 maximum potential payout. Actual shares awarded at the end of the performance period may be less than the maximum potential payout level depending on achievement of performance-based award objectives.
	To satisfy the vesting of its RSU awards, the Company has issued new shares from its authorized but unissued shares. Any additional granted awards will also be issued from the Company’s authorized but unissued shares. Under the LTIP, there are 384,398 common shares currently available for additional RSU grants.
	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 LTIP 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 stock 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, 2014, 249,931 shares have been deferred and are being held by the rabbi trust.
	Share Option Awards
	The LTIP 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. At September 30, 2014 there were 35,000 shares remaining available for issuance under the LTIP. Options issued to date under the Plan 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. Forfeitures have been estimated to be zero.
	There were 22,000 and 0 options granted for the nine months ended September 30, 2014 and 2013, respectively.
	The fair value for the stock options granted in 2014 was estimated at the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:
		2014
	Risk-free interest rate		1.8	%
	Dividend yield		1.7	%
	Expected life (years)		5
	Expected volatility		44.3	%
	Activity in the Company’s LTIP plan for the nine months ended September 30, 2014 was as follows:
		Number of			Weighted		Weighted		Aggregate
		Shares			Average		Average		Intrinsic
					Exercise Price		Remaining		Value
					per Share		Contractual
							Term (Years)
	Outstanding at January 1, 2014		17,000		$	54.2
	Granted		22,000		$	68.2
	Exercised		(1,250	)	$	52.1
	Forfeited		(2,750	)	$	67.5
	Outstanding (vested and expected to vest) at September 30, 2014		35,000		$	62.03		8.6	$	269
	Exercisable at September 30, 2014		11,375		$	54.3		7.4	$	4
	The weighted-average grant-date fair value of options granted during 2014 was $24.02. There were 1,250 and 12,750 stock options exercised during the nine months ended September 30, 2014 and 2013, respectively. The total intrinsic value of stock options exercised during the nine months ended September 30, 2014 and 2013 was less than $.1 million and $.3 million, respectively. Cash received for the exercise of stock options during the nine months ended September 30, 2014 and 2013 was $.1 million and $.6 million, respectively. Excess tax benefits from share-based options for the nine months ended September 30, 2014 and 2013 were $0 and $.1 million, respectively.
	For the three and nine months ended September 30, 2014, the Company recorded compensation expense related to the stock options currently vesting of $.1 million and $.2 million, respectively. For the three and nine months ended September 30, 2013, the Company recorded compensation expense related to the stock options currently vesting of less than $.1 million and $.1 million, respectively. The total compensation cost related to nonvested awards not yet recognized at September 30, 2014 is expected to be a combined total of $.4 million over a weighted-average period of approximately 2.3 years.

	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, 2014, the fair value of the Company’s long-term debt was estimated using discounted cash flows analysis, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements which are considered to be level two inputs. There have been no transfers in or out of level two for the nine months ended September 30, 2014. Based on the analysis performed, the fair value of the Company’s long-term debt approximates its carrying value as of September 30, 2014 and December 31, 2013.

	NOTE I – RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS
	In March 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2013-05, “Foreign Currency Matters (Topic 830): Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity.” ASU 2013-05 clarifies the applicable guidance for the release of the cumulative translation adjustment under current U.S. GAAP by emphasizing that the accounting for the release of the cumulative translation adjustment into net income for sales or transfers of a controlling financial interest within a foreign entity is the same irrespective of whether the sale or transfer is of a subsidiary or a group of assets that is a nonprofit activity or business. When a reporting entity ceases to have a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity, the parent is required to apply the guidance in Subtopic 830-30 to release any related cumulative translation adjustment into net income. The amendments are effective prospectively for fiscal years (and interim reporting periods within those years) beginning after December 15, 2013. The Company adopted the guidance in the first quarter of 2014 and it did not have an effect on the Company’s results of operations, financial condition or cash flow.

New Accounting Standards to be Adopted	'
	NOTE J – NEW ACCOUNTING STANDARDS TO BE ADOPTED
	In April 2014, the FASB issued ASU 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity”, or ASU 2014-08. ASU 2014-08 changes the criteria for reporting a discontinued operation. Under the new pronouncement, a disposal of a part of an organization that has a major effect on its operations and financial results is a discontinued operation. The Company is required to adopt ASU 2014-08 prospectively for all disposals or components of the business classified as held for sale during fiscal period beginning after December 15, 2014 and 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. The amendment is effective for annual reporting periods beginning after December 15, 2016. Early adoption is not permitted. The Company is currently evaluating what impact, if any, its adoption will have to the Company’s consolidated financial statements.
	In August 2014, the FASB issued ASU 2014-15 “Presentation of Financial Statements – Going Concern (Subtop 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. ASU 2014-15 provides guidance in GAAP about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The Company is required to adopt ASU 2014-15 prospectively for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The Company is currently evaluating what impact, if any, its adoption will have to the presentation of the Company’s consolidated financial statements.

	NOTE L – INCOME TAXES
	The Company’s effective tax rate was 52% and 29% for the three months ended September 30, 2014 and 2013, respectively; and 39% and 33% for the nine months ended September 30, 2014 and 2013, respectively. The higher effective tax rate for the three and nine months ended September 30, 2014 compared to the U.S. federal statutory tax rate of 35% was primarily due to the Company providing a valuation allowance against deferred tax assets, attributable to operating losses in certain foreign jurisdictions coupled with a decrease in earnings in jurisdictions with lower tax rates than the U.S. federal statutory rate, where such earnings are permanently reinvested. The higher effective tax rate for the nine months ended September 30, 2014 compared with the same period for 2013 was primarily due to the Company’s decision not to recognize the tax benefit attributable to operating losses in certain foreign jurisdictions coupled with a decrease in earnings in jurisdictions with lower tax rates than the U.S. federal statutory rate, where such earnings are permanently reinvested.
	The Company provides valuation allowances against deferred tax assets when it is more likely than not that some portion, or all, of its deferred tax assets will not be realized. The Company recorded a $.7 million valuation allowance as a discrete item against deferred tax assets existing as of December 31, 2013 for one of its foreign operations during the nine months ended September 30, 2014.
	As of September 30, 2014, the Company had gross unrecognized tax benefits of approximately $.6 million with no significant changes during the nine months ended September 30, 2014. The Company does not anticipate any material changes to the amount of unrecognized tax benefits within the next twelve months.
