Accounting Policies [Abstract]
Significant Accounting Policies	Note A - Significant Accounting Policies Nature of Operations Preformed Line Products Company and subsidiaries (the “Company”) is a designer and manufacturer of products and systems employed in the construction and maintenance of overhead and underground networks for the energy, telecommunication, cable operators, data communication and other similar industries. The Company’s primary products support, protect, connect, terminate and secure cables and wires. The Company also provides solar hardware systems and mounting hardware for a variety of solar power applications. The Company’s customers include public and private energy utilities and communication companies, cable operators, governmental agencies, contractors and subcontractors, distributors and value-added resellers. The Company serves its worldwide markets through strategically located domestic and international manufacturing facilities. Principles of Consolidation and Noncontrolling Interests The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries for which it has a controlling interest. All intercompany accounts and transactions have been eliminated upon consolidation. Noncontrolling interests are presented in the Company’s Consolidated Financial Statements as if parent company investors (controlling interests) and other minority investors (noncontrolling interests) in partially owned subsidiaries have similar economic interests in a single entity. As a result, investments in noncontrolling interests are reported as equity in our Consolidated Financial Statements. Additionally, the Company’s Consolidated Financial Statements include 100 % of a controlled subsidiary’s earnings, rather than only our share. Transactions between the parent company and noncontrolling interests are reported in equity as transactions between stockholders, provided that these transactions do not create a change in control. Cash and Cash Equivalents Cash, cash equivalents and restricted cash (“Cash”) are stated at fair value and consist of highly liquid investments with original maturities of three months or less at the time of acquisition. Restricted cash is included on the Cash and cash equivalents on the Company’s Consolidated Balance Sheets. Accounts Receivable Allowances The Company maintains an allowance for credit losses for estimated losses resulting from the inability of its customers to make required payments. Prior to the adoption of Financial Accounting Standards Board (“FASB”) ASC 326 “Financial Instruments – Credit Losses", the allowances for uncollectible accounts receivable were based upon the number of days the accounts are past due, the current business and macroeconomic environment, geographic considerations and specific information such as bankruptcy or liquidity issues of its customers. Rather than recognizing losses when they are deemed to be probable, the Company now uses a current expected credit loss model in order to immediately recognize an estimate of credit losses that are expected to occur over the life of the financial instruments, mainly trade receivables. Additionally, the allowance is based upon identified delinquent accounts, customer payment patterns and other analyses of historical data trends. The Company also maintains an allowance for future sales credits related to sales recorded during the year. The estimated allowance is based on historical sales credits issued in the subsequent year related to the prior year and any significant, preapproved open return good authorizations as of the balance sheet date. Inventories The Company uses the last-in, first-out (“LIFO”) method of determining cost for the majority of its material portion of inventories in PLP-USA. All other inventories are determined by the first-in, first-out (“FIFO”) or average cost methods. Inventories are carried at net realizable value. Reserves are maintained for estimated obsolescence or excess inventory based on past usage and future demand. Fair Value of Financial Instruments Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) 825, “Disclosures about Fair Value of Financial Instruments,” requires disclosures of the fair value of financial instruments. The estimated fair value of financial instruments was principally based on market prices where such prices were available, and when unavailable, fair values were estimated based on market prices of similar instruments. Property, Plant and Equipment and Depreciation Property, plant, and equipment is recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives. The estimated useful lives used, when purchased new, are: land improvements, ten years ; buildings, forty years ; building improvements, five to forty years ; machinery and equipment, three to ten years ; and aircraft, fifteen years . Appropriate reductions in estimated useful lives are made for property, plant and equipment purchased in connection with an acquisition of a business or in a used condition when purchased. Long-Lived Assets The Company records impairment losses on long-lived assets used in operations when events and circumstances indicate that the carrying value of the assets are impaired and the undiscounted future cash flows estimated to be generated by such assets are less than the carrying value. The Company’s cash flows are based on historical results adjusted to reflect the Company’s best estimate of future market and operating conditions. The net carrying value of assets not recoverable is then reduced to fair value. The estimate of fair value represents the Company’s best estimate based on industry trends and reference to market rates and transactions. The Company did not record any impairment to long-lived assets during the years ended December 31, 2021 and 2020. Goodwill and Other Intangibles Goodwill and other intangible assets are generally recoded as a result of a business acquisition. Goodwill represents the excess of purchase price over the fair value of the tangible and identifiable net assets acquired during a business combination and is not subject to amortization but is subject to annual impairment testing. Goodwill is reviewed for impairment annually on October 1 or more frequently when changes in circumstances indicate the carrying amount may be impaired. Such events or changes may include, but are not limited to, a significant deterioration in overall economic conditions, changes in the business climate of the Company's industry, overall performance indicators, a decline in the Company's market capitalization, business reorganization or restructuring or disposal of all or part of a reporting unit. Goodwill is tested for impairment at the reporting unit level, and is based on the net assets for each reporting unit, including goodwill and intangible assets. The Company’s reporting units are equivalent to the reportable operating segments, except for the Americas segment which has two reporting units (Canada and Other Americas). Goodwill is assigned to each reporting unit, as this represents the lowest level that constitutes a business and is the level at which management regularly reviews the operating results. The Other Americas reporting unit does not have any allocated goodwill. Intangible assets with definite lives, consisting primarily of purchased customer relationships, patents, technology, customer backlogs, trademarks and land use rights, are generally amortized over periods from four years to eighty-two years . The Company has no indefinite lived intangible assets other than goodwill. The Company’s intangible assets with finite lives are generally amortized over the period in which the economic benefits of the intangibles are consumed, using either a projected cash flow basis method or the straight-line method. The straight-line method is used in circumstances in which it better reflects the pattern in which the economic benefits of the intangible asset are consumed or otherwise expire compared to using a projected cash flow basis method. An evaluation of the remaining useful life of intangible assets with a determinable life is performed on a periodic basis and when events and circumstances warrant an evaluation. The Company assesses intangible assets with a determinable life for impairment when the carrying amount may not be recoverable, consistent with its policy for assessing other long-lived assets. Approximately $ 0.3 million of impairment charges were recorded in 2021 related to finite-lived intangible assets. The Company may use both quantitative and qualitative approaches when testing goodwill for impairment. A qualitative analysis is performed by assessing certain trends and factors, including projected market outlook and growth rates, forecasted and actual sales and gross profit margins, discount rates and other relevant qualitative factors. These trends and factors are compared to, and based on, the assumptions used in the most recent quantitative analysis performed for each reporting unit to determine if it is more likely than not that the fair value of the reporting unit exceeds its carrying amount. If that determination is made, no further evaluation is necessary. Otherwise, the Company performs a quantitative impairment test on the reporting unit. For the quantitative approach, the Company uses a combination of the income approach, which uses a discounted cash flow methodology, and the market approach, which uses comparable market multiples, 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. The fair value estimates are subjective and sensitive to significant assumptions, such as future cash flows, revenue growth rates, operating margins, the weighted-average cost of capital ("WACC"), and estimated market multiples, of which are affected by expectations of future market or economic conditions. The future cash flows are based on the Company’s long-term operating plan and a terminal value was used to estimate the reporting unit’s cash flows beyond the period covered by the operating plan. The WACC is an estimate of the overall after-tax rate of return required by equity and debt market holders of a business enterprise. The Company believes that the methodologies, significant assumptions, and weightings used are reasonable and result in appropriate fair values of the reporting units. Impairment assessments inherently involve management judgments regarding a number of assumptions such as those described above. Due to the multiple variables inherent in arriving at the estimates of the reporting unit's fair value, differences in assumptions could have an effect on the estimated fair value of a reporting unit and could result in goodwill impairment charges in a future period. Revenue Recognition Net sales include products and shipping and handling charges, net of estimates for product returns. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products. All revenue is recognized when the Company satisfies the performance obligations under the contract and control of the product is transferred to the customer, primarily based on shipping terms. Revenue for shipping and handling charges are recognized at the time the products are shipped to, delivered to or picked up by the customer. Payment terms vary by the type and location of the customer and the products offered but are generally short-term in nature. The Company estimates product returns based on historical return rates. Research and Development Research and development costs for new products are expensed as incurred and totaled $ 3.3 million in 2021, $ 2.8 million in 2020 and $ 3.0 million in 2019. Income Taxes Income taxes are computed in accordance with the provisions of FASB ASC 740, “Income Taxes” and includes U.S. (federal and state) and foreign income taxes. In the Consolidated Financial Statements, the benefits of a consolidated return have been reflected where such returns have or could be filed based on the entities and jurisdictions included in the financial statements. Uncertain tax positions are recorded in accordance with ASC 740 on the basis of a two-step process whereby (1) the Company determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, the Company recognizes the largest amount of tax benefit that is more than likely than not to be realized upon ultimate settlement with the related tax authority. Deferred taxes are recognized at currently enacted tax rates for temporary differences between the financial reporting and income tax basis of assets and liabilities and operating loss and tax credit carryforwards. The Company establishes a valuation allowance to record deferred tax assets at an amount that is more-likely-than-not to be realized. In the event the Company were to determine that it would be able to realize our deferred tax assets in the future in excess of the recorded amount, an adjustment to the valuation allowance would increase income in the period such determination was made. Likewise, should the Company determine that it would not be able to realize all or part of the net deferred tax assets in the future, an adjustment to the valuation allowance would be charged to expense in the period such determination was made. Advertising Advertising costs are expensed as incurred and totaled $ 1.5 million in 2021, $ 0.3 million in 2020 and $ 1.9 million in 2019. Foreign Currency Translation Asset and liability accounts are translated into U.S. dollars using exchange rates in effect at the date of the Consolidated Balance Sheet. The translation adjustments are recorded in Accumulated other comprehensive income (loss). Revenues and expenses are translated at weighted average exchange rates in effect during the period. Transaction gains and losses arising from exchange rate changes on transactions denominated in a currency other than the functional currency are included in income and expense as incurred. Aggregate transaction losses, including hedge activity, for both years ended December 31, 2021 and 202 0 was $ 1.0 milli on and was $ 1.2 million for the year ended December 31, 2019. Upon sale or substantially complete liquidation of an investment in a foreign entity, the cumulative translation adjustment for that entity is reclassified from Accumulated other comprehensive income (loss) to earnings. Effective July 1, 2018, Argentina was designated as a highly inflationary economy as the projected three-year cumulative inflation rate exceeded 100 %. As such, beginning July 1, 2018, the functional currency for the Company’s Argentina subsidiary became the U.S. dollar. The impact to the Company’s consolidated financial statements for accounting of the Argentina subsidiary under highly inflationary economy rules is not material. Revenue from operations in Argentina was less than 1 % of total consolidated net sales for both years ended December 31, 2021 and 2020 and less than 2 % of consolidated net sales for the year ended December 31, 2019. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates. Business Combinations Upon acquisition of a business, the Company uses the income, market or cost approach (or a combination thereof) for the valuation as appropriate. The valuation inputs in these models and analyses are based on market participant assumptions. Market participants are considered to be buyers and sellers unrelated to the Company in the principal or most advantageous market for the asset or liability. In the event there is an earn-out associated with an acquisition, the Company uses a valuation model to measure the contingent consideration, which may include significant assumptions such as revenue projections and discount rates. The Company uses a discounted cash flow model to measure the useful lives of intangible assets. The significant assumptions used to estimate the fair value of the intangible assets include discount rates and certain assumptions that form the basis of future cash flows (such as revenue growth rates, attrition rates, and royalty rates). These assumptions relate to the future performance of the acquired businesses, are forward-looking and could be affected by future economic and market conditions. Fair value estimates are based on a series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. Management values property, plant and equipment using the cost approach supported where available by observable market data, which includes consideration of obsolescence. Acquired inventories are marked to fair value. For certain items, the carrying value is determined to be a reasonable approximation of fair value based on information available to the Company. Derivative Financial Instruments The Company operates internationally and enters into intercompany transactions denominated in foreign currencies. Consequently, the Company is subject to market risk arising from exchange rate movements between the dates foreign currency transactions occur and the dates they are settled. The Company currently uses foreign currency forward contracts to reduce the risk related to some of these transactions. These contracts usually have maturities of 90 days or less and generally require an exchange of foreign currencies for U.S. dollars at maturity at rates stated in the contracts. These contracts are not designated as hedging instruments under U.S. GAAP. Accordingly, the changes in the fair value of the foreign currency forward contracts are recognized in each accounting period in “Other operating expense - net” on the Consolidated Statements of Income together with the transaction gain or loss from the related balance sheet position. The Company records the contracts at fair value in the Consolidated Balance Sheets. The Company does not hold derivatives for trading purposes. Recently Adopted Accounting Pronouncements On January 1, 2021 , the Company adopted Account Standards Update (ASU) 2019-12 , Income Taxes (ASC 740) – Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC 740 and also clarifies and amends existing guidance to improve consistent application. The adoption of ASU 2019-12 did not have a material impact on the Consolidated financial statements. No other recently issued or effective ASU's had, or are expected to have, a material impact on the Company's results of operations, financial condition or liquidity.

Machinery, equipment and aircraft includes $ 0.6 million and $ 0.3 million of financing leases at December 31, 2021 and 2020, respectively. Legal proceedings The Company can be party to a variety of pending legal proceedings and claims arising in the normal course of business, including, but not limited to, litigation relating to employment, workers’ compensation, product liability, environmental and intellectual property. The Company has liability insurance to cover many of these claims. Although the outcomes of these matters are not predictable with certainty, the Company records a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. In the event the Company determines that a loss is not probable, but is reasonably possible, and the likelihood to develop what the Company believes to be a reasonable range of potential loss exists, the Company will include disclosure related to such matters. To the extent that there is a reasonable possibility the losses could exceed amounts already accrued, the Company will adjust the accrual in the period in which the determination is made, disclose an estimate of the additional loss or range of loss and if the amount of such adjustment cannot be reasonably estimated, disclose that an estimate cannot be made. During the years ended December 31, 2021 and 2020, the Company maintained approximately $ 2.3 million and $ 2.2 million, respectively, representing its best estimate for losses to be incurred on global legal matters. 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 $ 56.0 million Canadian dollars 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 Company believes the claims against it are without merit and intends to vigorously defend against such claims. The Company is unable to predict the outcome of this case, however, it has recorded a reserve for the low end of the range for potential loss associated with this matter. If this matter is concluded in a manner adverse 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 flow.

Retirement Benefits [Abstract]
Pension Plans	Note C - Pension Plans PLP-USA hourly employees of the Company who meet specific requirements as to age and length and date of service are covered by a defined benefit pension plan (“Plan”). On December 12, 2012, the Company approved a freeze on further benefit accruals under the Plan and notified the participants of the freeze on December 19, 2012. Beginning February 1, 2013, participants ceased earning additional benefits under the Plan and no new participants entered the Plan. The Company uses a December 31 measurement date for its Plan. Net periodic pension cost for the Plan consists of the following components for the year ended December 31: 2021 2020 2019 Service cost $ 0 $ 0 $ 299 Interest cost 1,138 1,301 1,411 Expected return on plan assets ( 2,343 ) ( 2,251 ) ( 1,946 ) Recognized net actuarial loss 614 475 520 Net periodic pension (income) cost $ ( 591 ) $ ( 475 ) $ 284 The following tables set forth benefit obligations, plan assets and the accrued benefit cost of the Plan at December 31: 2021 2020 Projected benefit obligation at beginning of the year $ 42,582 $ 37,936 Interest cost 1,138 1,301 Actuarial (gain) loss ( 958 ) 4,590 Benefits paid ( 1,352 ) ( 1,245 ) Projected benefit obligation at end of year $ 41,410 $ 42,582 Fair value of plan assets at beginning of the year $ 36,756 $ 32,658 Actual return on plan assets 2,353 5,013 Employer contributions 0 330 Benefits paid ( 1,352 ) ( 1,245 ) Fair value of plan assets at end of the year $ 37,757 $ 36,756 Unfunded pension obligation $ 3,653 $ 5,826 The actuarial gain in 2021 was primarily the result of an increase in the Plan discount rate from 3.50 % in 2020 to 2.69 % in 2021. In accordance with ASC 715-20, the Company recognizes the underfunded status of the Plan as a liability. The amount recognized in Accumulated other comprehensive loss related to the Plan at December 31 is comprised of the following: 2021 2020 Balance at January 1 $ ( 6,704 ) $ ( 5,671 ) Reclassification adjustments: Pre-tax amortized net actuarial gain 614 475 Tax provision ( 145 ) ( 112 ) 469 363 Adjustment to recognize (gain) loss on unfunded Pre-tax gain (loss) 968 ( 1,829 ) Tax (provision) / benefit ( 229 ) 433 739 ( 1,396 ) Balance at December 31 $ ( 5,496 ) $ ( 6,704 ) The 2021 pre-tax unfunded pension obligation gain of $ 1.0 million included a gain of $ 1.5 million due to a .23 % increase in the discount rate to 2.92 %, a loss of $ 0.1 million associated with the industry updates to the mortality table used and a loss of $ 0.3 million due to demographic changes. Asset performance exceeding the 6.50 % rate of return assumption had a negligible effect on the unfunded obligation. There is no prior service cost to be amortized in the future. The Plan had accumulated benefit obligations in excess of Plan assets as follows: 2021 2020 Accumulated benefit obligation $ 41,410 $ 42,582 Fair market value of assets 37,757 36,756 Weighted-average assumptions used to determine benefit obligations at December 31: 2021 2020 Discount rate 2.92 % 2.69 % Rate of compensation increase n/a n/a Weighted -average assumptions used to determine net periodic benefit cost at December 31: 2021 2020 2019 Discount rate 2.69 % 3.50 % 3.50 % Rate of compensation increase n/a n/a n/a Expected long-term return on plan assets 6.50 % 7.00 % 7.00 % The net periodic pension cost for 2021 was based on a long-term asset rate-of-return of 6.50 %. This rate is based upon management’s estimate of future long-term rates of return on similar assets and is consistent with historical returns on such assets. At December 31, 2021 and 2020, the Plan’s pooled investment funds were measured at fair value using the net asset value ("NAV"). The NAV is based on the value of the assets owned by the plan, less liabilities. These pooled assets are not quoted on an active exchange. The fair value of the Plan assets at December 31, 2021 and 2020 was $ 37.8 million and $ 36.8 million, respectively. The Plan weighted-average asset allocations at December 31, 2021 and 2020, by asset category, are as follows: Plan assets at December 31 2021 2020 Asset category Equity securities 49 % 47 % Debt securities 51 53 100 % 100 % Management seeks to maximize the long-term total return of financial assets consistent with the fiduciary standards of ERISA. The ability to achieve these returns is dependent upon the need to accept moderate risk to achieve long-term capital appreciation. In recognition of the expected returns and volatility from financial assets, Plan assets are invested in the following ranges with the target allocation noted: Range Target Equities 40 - 60 % 50 % Fixed Income 40 - 60 % 50 % Cash Equivalents 0 - 10 % 0 % Investment in these markets is projected to provide performance consistent with expected long-term returns with appropriate diversification. The Company's policy is to fund amounts deductible for federal income tax purposes. The Company is currently evaluating the option to contribute to the Plan in 2022. The benefits expected to be paid out of the Plan assets in each of the next five years and the aggregate benefits expected to be paid for the subsequent five years are as follows: Year Pension Benefits 2022 $ 1,385 2023 1,467 2024 1,550 2025 1,624 2026 1,690 2027-2031 9,728 The Company also provides retirement benefits through various defined contribution plans including PLP-USA’s Profit Sharing Plan. Expense for these defined contribution plans was $ 5.8 million in 2021, $ 5.9 million in 2020 and $ 4.9 million in 2019. Further, the Company also provides retirement benefits through the Supplemental Profit Sharing Plan. To the extent an employee’s award under PLP-USA’s Profit Sharing Plan exceeds the maximum allowable contribution permitted under existing tax laws, the excess is accrued for (but not funded) under a non-qualified Supplemental Profit Sharing Plan. The Supplemental Profit Sharing Plan allows participants the ability to hypothetically invest their proportionate award into various investment options, which primarily includes mutual funds. Expense for the Supplemental Profit Sharing Plan was $ 0.9 million for the year ended December 31, 2021 and $ 1.1 million for both years ended December 31, 2020 and 2019. The Supplemental Profit Sharing Plan unfunded status for the years ended December 31, 2021 and 2020 was $ 8.0 million and $ 7.1 million, respectively, and is included in Other noncurrent liabilities.

Leases	Note F - Leases The Company regularly enters into leases in the normal course of business. As of December 31, 2021, the leases in effect were related to land, buildings, vehicles, office equipment and other production equipment under operating leases with lease terms of up to 99 years. The Company often has the option to renew lease terms for buildings and other assets. The exercise of lease renewal options is generally at the Company’s sole discretion. In addition, certain lease arrangements may be terminated prior to their original expiration date at the Company’s discretion. The Company evaluates renewal and termination options at the lease commencement date to determine if the Company is reasonably certain to exercise the option on the basis of economic factors. The weighted average remaining lease term for the Company’s operating and financing leases as of December 31, 2021 was 18.4 and 3.0 years, respectively. Lease expense is recognized for these leases on a straight-line basis over the lease term with variable lease payments recognized in the period those payments are incurred. The components of operating and finance lease costs are recognized in Costs and expenses and Interest expense, respectively, on the Company’s Consolidated Statements of Income. The Company’s operating and finance lease costs for the years ended December 31, 2021 and 2020 were as follows: Year Ended December 31 2021 2020 Components of lease expense Operating lease cost $ 2,870 $ 2,957 Finance lease cost Amortization of right-of-use assets 388 66 Interest on lease liabilities 13 9 Total lease cost $ 3,271 $ 3,032 The discount rate implicit within each lease is often not determinable and, therefore, the Company establishes the discount rate based on its incremental borrowing rate. The incremental borrowing rate for the Company’s leases is determined based on lease term and currency in which lease payments are made, adjusted for impacts of collateral. The weighted average discount rate used to measure the Company’s operating and finance lease liabilities as of December 31, 2021 was 4.96 % and 4.21 %, respectively. The weighted average discount rate used to measure the Company’s operating and finance lease liabilities as of December 31, 2020 was 4.46 % and 4.33 %, respectively. Future maturities of the Company’s lease liabilities as of December 31, 2021 are as follows: Year Ended December 31, 2021 Operating Leases Finance Leases 2022 $ 2,448 $ 267 2023 1,762 146 2024 1,019 100 2025 883 82 2026 and thereafter 9,713 20 Total lease payments $ 15,825 $ 615 Less amount of lease payment representing interest 5,685 6 Total present value of lease payments $ 10,140 $ 609 Amounts recognized as finance lease obligations are reported in Accrued expense and other liabilities and Other noncurrent liabilities in the Consolidated Balance sheets. The Company received sublease income of $ 1.0 million for both years ended December 31, 2021 and 2020. The total minimum sublease rentals under noncancelable subleases to be received through 2023 is $ 1.6 million. Supplemental cash flow information related to leases for the years ended December 31, 2021 and 2020 was as follows: Year Ended December 31 2021 2020 Supplemental cash flow information Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 2,608 $ 2,793 Operating cash flows from finance leases 13 9 Financing cash flows from finance leases 375 118

Income Tax Disclosure [Abstract]
Income Taxes	Note G - Income Taxes The Company recorded net tax provisions of $ 13.2 million, $ 10.8 million, and $ 8.1 million for the years ended December 31, 2021, 2020, and 2019, respectively. Cash taxes paid, net of refunds, were $ 16.9 million, $ 7.7 million, and $ 7.8 million for the years ending December 31, 2021, 2020, and 2019, respectively. The 2021 payment includes a $ 5.0 million extension payment during the year ended December 31, 2021 which was related to the 2020 tax return. Income before income taxes was derived from the following sources: 2021 2020 2019 United States $ 32,570 $ 22,725 $ 11,353 Foreign 16,326 17,846 20,105 $ 48,896 $ 40,571 $ 31,458 The components of income taxes for the years ended December 31 are as follows: 2021 2020 2019 Current Federal $ 649 $ 7,909 $ 2,835 Foreign 5,065 5,093 6,170 State and local 917 1,188 391 6,631 14,190 9,396 Deferred Federal 7,172 ( 2,290 ) ( 10 ) Foreign ( 75 ) ( 445 ) ( 1,347 ) State and local ( 553 ) ( 645 ) 83 6,544 ( 3,380 ) ( 1,274 ) Income taxes $ 13,175 $ 10,810 $ 8,122 The differences between the provision for income taxes at the U.S. federal statutory rate and the tax shown in the Statements of Consolidated Income for the years ended December 31 are summarized as follows: 2021 2020 2019 U. S. federal statutory tax rate 21.0 % 21.0 % 21.0 % Federal tax at statutory rate $ 10,268 $ 8,520 $ 6,606 State and local taxes, net of federal benefit 721 942 308 Non-deductible officers' compensation 763 1,161 1,005 Other U.S. federal permanent items 35 162 ( 384 ) Global intangible low-taxed income 770 1,222 1,738 Foreign tax credits ( 1,222 ) ( 1,204 ) ( 1,422 ) Non-U.S. tax rate variances 2,936 1,330 929 Valuation allowance ( 738 ) ( 245 ) ( 346 ) Tax credits ( 807 ) ( 349 ) ( 464 ) Other, net 449 ( 729 ) 152 $ 13,175 $ 10,810 $ 8,122 Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the tax basis of assets and liabilities and their carrying value for financial statement purposes. The tax effects of temporary differences that give rise to the Company’s deferred tax assets and liabilities at December 31 are as follows: 2021 2020 Deferred tax assets: Accrued compensation and benefits $ 1,175 $ 1,518 Inventory valuation reserves 2,504 2,535 Allowance for credit losses 663 480 Benefit plan reserves 7,048 7,564 Net operating loss carryforwards 2,383 1,851 Foreign tax credit 543 0 Other accrued expenses 2,453 3,825 Unrealized foreign exchange 213 799 Other 0 284 Gross deferred tax assets 16,982 18,856 Valuation allowance ( 1,932 ) ( 2,912 ) Net deferred tax assets 15,050 15,944 Deferred tax liabilities: Depreciation and other basis differences ( 11,023 ) ( 4,514 ) Intangibles ( 2,594 ) ( 3,419 ) Other ( 404 ) ( 69 ) Deferred tax liabilities ( 14,021 ) ( 8,002 ) Net deferred tax assets $ 1,029 $ 7,942 2021 2020 Change in net deferred tax assets: Deferred income tax expense Ordinary movement $ ( 6,544 ) $ 3,380 Items of other comprehensive (loss) income ( 371 ) 319 Currency translation 2 ( 205 ) Total change in net deferred tax assets $ ( 6,913 ) $ 3,494 Deferred taxes are recorded at a rate at which such items are expected to reverse based on currently enacted tax rates for temporary differences between the financial reporting and income tax basis of assets and liabilities and operating loss and tax credit carryforwards. At December 31, 2021, the Company had $ 13.8 million of foreign net operating loss carryforwards of which $ 9.2 million has an indefinite carryforward and $ 4.6 million will expire between the years 2024 and 2030 . The Company assesses the available positive and negative evidence to determine if it is more likely than not that sufficient future taxable income will be generated to utilize the existing deferred tax assets by jurisdiction. Based on this evaluation, the Company has established a valuation allowance of $ 1.9 million at December 31, 2021 in order to measure only the portion of the deferred tax asset that is more likely than not to be realized. The net decrease in the valuation allowance during the year was $ 1.0 million, of which $ 0.7 million impacts the income tax provision and the remainder relates to currency translation. The Company considers the majority of the earnings in our non-U.S. subsidiaries to be permanently reinvested and accordingly did not record any associated deferred income taxes on such earnings. Accordingly, the Company intends to continue to invest approximately $ 114.9 million of such earnings, as well as our capital in these subsidiaries, indefinitely outside of the U.S. The Company is subject to taxation in the U.S. and various state and foreign jurisdictions. As of December 31, 2021, with few exceptions, the Company is no longer subject to U.S. federal examinations by tax authorities for years before 2017 and state, local or foreign examinations by tax authorities for years before 2015. The following is a tabular reconciliation of the total amounts of unrecognized tax benefits related to uncertain tax positions, excluding interest and penalties, for the year ended December 31: 2021 2020 2019 Balance at January 1 $ 66 $ 118 $ 0 Additions for tax positions of prior years 0 0 118 Expiration of statutes of limitations ( 66 ) ( 52 ) 0 Balance at December 31 $ 0 $ 66 $ 118 The Company records accrued interest as well as penalties related to unrecognized tax benefits as part of the provision for income taxes. During the year ended December 31, 2021, the remaining portion of the Company’s uncertain tax position which was $ 0.1 million expired due to the statute of limitation taking effect. The Company had no significant activity with regard to unrecognized tax benefits. The Company had less than $ 0.1 million of accrued interest and penalties as of December 31, 2021.

Share-Based Compensation

Share-Based Compensation	12 Months Ended

Share-based Payment Arrangement [Abstract]
Share-Based Compensation	Note H - Share-Based Compensation 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 were reserved for share options. The Preformed Line Products Company 2016 Incentive Plan (the “Incentive Plan”) was put in place 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. As of December 31, 2021, 43,500 options and 380,278 restricted shares have been granted under the Incentive Plan. 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, 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. Dividends declared are accrued. A summary of the RSUs for the year ended December 31, 2021 is as follows: Restricted Share Awards Performance Total Weighted-Average and Service Service Restricted Grant-Date Required (1) Required Awards Fair Value Nonvested as of January 1, 2021 183,777 15,786 199,563 $ 60.33 Granted 51,308 12,285 63,593 71.84 Vested ( 56,973 ) ( 7,198 ) ( 64,171 ) 71.77 Forfeited ( 5,145 ) ( 1,286 ) ( 6,431 ) 54.55 Nonvested as of December 31, 2021 172,967 19,587 192,554 $ 60.34 (1) Nonvested, performance-based RSU's are reflected above 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. Annual compensation expense related to the time-based RSUs for the years ended December 31, 2021, 2020 and 2019 was $ 0.5 million, $ 0.4 million and $ 0.5 million, respectively. During the year ended December 31, 2021, a former Officer of the Company forfeited 1,286 time-based RSUs that were granted during 2020 and 2019. As of December 31, 2021, there was $ 0.7 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 1.8 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 pre-tax income and sales growth over a requisite performance period. Depending on the extent to which the performance criteria are satisfied under the LTIP, the participants are eligible to earn common shares over the vesting period. Performance-based compensation expense for the years ended December 31, 2021, 2020 and 2019 was $ 3.4 million, $ 3.5 million and $ 3.9 million, respectively. During the year ended December 31, 2021, a former Officer of the Company forfeited 5,145 performance-based RSUs that were granted during 2020 and 2019. As of December 31, 2021, the remaining performance-based RSUs compensation expense of $ 3.7 million is expected to be recognized over a period of approximately 1.7 years. The excess tax benefits from service and performance-based RSUs was $ 0.2 million, $ 0.4 million and $ 0.5 million for the years ended December 31, 2021, 2020 and 2019, respectively. This represents the reduction in income taxes otherwise payable during the period attributable to the actual gross tax benefits in excess of the expected tax benefits for restricted shares vested in the current period. In the event of a Change in Control (as defined in the LTIP and Incentive Plan), vesting of the RSUs will be accelerated and all restrictions will lapse. Nonvested performance-based awards are based on a maximum target 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 RSUs, the Company has reserved new shares from its authorized but unissued shares. Any additional granted awards will also be issued from the Company’s authorized but unissued shares. 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 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 December 31, 2021, 243,138 LTIP shares have been deferred and are being held by the rabbi trust. 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 and Incentive 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 3,000 options granted during the year ended December 31, 2021 and 25,500 and 5,000 options granted in the years ended December 31, 2020 and 2019, respectively. The fair values for the stock options granted were estimated at the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions: 2021 2020 2019 Risk-free interest rate 1.1 % 1.8 % 1.8 % Dividend yield 1.4 % 1.6 % 1.6 % Expected life (years) 5 5 5 Expected volatility 39.7 % 42.0 % 42.0 % Activity in the Company’s LTIP and Incentive Plan for the year ended December 31, 2021 was as follows: Number of Weighted Weighted Aggregate Outstanding at January 1, 2021 50,950 $ 54.81 Granted 3,000 $ 69.89 Exercised ( 7,000 ) $ 47.66 Forfeited 0 - Outstanding (vested and expected to vest) at 46,950 $ 56.84 6.4 $ 454 Exercisable at December 31, 2021 29,950 $ 57.39 5.2 $ 325 The weighted-average grant-date fair value of options granted during 2021 was $ 69.89 . There were 7,000 , 5,050 , and 4,000 stock options exercised during the years ended December 31, 2021, 2020 and 2019, respectively. The total intrinsic value of stock options exercised was $ 0.2 million, $ 0.1 million for both years ended December 31, 2021 and 2020 and less than $ 0.1 million for the year December 31, 2019. Cash received for the exercise of stock options during the year ended December 31, 2021 was $ 0.3 million and $ 0.2 million during both years ended December 31, 2021 and 2020. The Company recorded compensation expense related to the stock options currently vested of $ 0.2 million, $ 0.1 million and less than $ 0.1 million during the years ended December 31, 2021, 2020 and 2019, respectively. The total compensation cost related to nonvested awards not yet recognized at December 31, 2021 is expected to be $ 0.2 million over a weighted-average period of approximately 1.6 years. The excess tax benefits from share-based awards for each of the years ended December 31, 2021, 2020 and 2019 was less than $ 0.1 million. This represents the reduction in income taxes otherwise payable during the period attributable to the actual gross tax benefits in excess of the expected tax benefits for options exercised in the current period.

Earnings Per Share [Abstract]
Computation of Earnings Per Share	Note I - 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 shares that were outstanding during the years presented. The calculation of basic and diluted earnings per share for the year ended December 31 was are as follows: 2021 2020 2019 Numerator Net income $ 35,729 $ 29,803 $ 23,303 Denominator Determination of shares (in thousands) Weighted-average common shares outstanding 4,907 4,923 5,031 Dilutive effect - share-based awards 63 61 56 Diluted weighted-average common shares outstanding 4,970 4,984 5,087 Earnings per common share Basic $ 7.28 $ 6.05 $ 4.63 Diluted $ 7.19 $ 5.98 $ 4.58 For the year ended December 31, 2021, 2020 and 2019, 13,000 , 37,919 and 15,041 stock options, respectively, 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 J - Goodwill and Other Intangibles The Company’s finite and indefinite-lived intangible assets consist of the following: December 31, 2021 December 31, 2020 Gross Carrying Accumulated Gross Carrying Accumulated Amount Amortization Amount Amortization Finite-lived intangible assets Patents $ 4,806 $ ( 4,806 ) $ 4,806 $ ( 4,806 ) Land use rights 1,293 ( 437 ) 1,286 ( 396 ) Trademark 1,837 ( 1,533 ) 1,756 ( 1,474 ) Technology 7,306 ( 2,830 ) 7,673 ( 2,402 ) Customer relationships 15,046 ( 8,643 ) 16,441 ( 8,441 ) $ 30,288 $ ( 18,249 ) $ 31,962 $ ( 17,519 ) Indefinite-lived intangible assets Goodwill $ 28,194 $ 29,508 The aggregate amortization expense for other intangibles with finite lives, ranging from 4 to 82 years, for the years ended December 31, 2021, 2020 and 2019 was $ 1.9 million, $ 1.8 million and $ 1.5 million, respectively. Amortization expense is estimated to be $ 1.7 million for 2022, $ 1.6 million for 2023 and 2024, $ 1.4 million for 2025 and $ 1.3 million for 2026. The weighted-average remaining amortization period is approximately 11.8 years. The weighted-average remaining amortization period by intangible asset class; land use rights, 54.4 years; trademark, 6.6 years; technology, 9.1 years and customer relationships, 8.6 years. Goodwill and other intangible assets are generally recoded as a result of a business acquisition. Goodwill represents the excess of purchase price over the fair value of the tangible and identifiable net assets acquired during a business combination and is not subject to amortization but is subject to annual impairment testing. Intangible assets with definite lives, consisting primarily of purchased customer relationships, patents, technology, customer backlogs, trademarks and land use rights, are generally amortized over periods from four years to eighty-two years . The Company’s intangible assets with finite lives are generally amortized over the period in which the economic benefits of the intangibles are consumed, using either a projected cash flow basis method or the straight-line method. The straight-line method is used in circumstances in which it better reflects the pattern in which the economic benefits of the intangible asset are consumed or otherwise expire compared to using a projected cash flow basis method. An evaluation of the remaining useful life of intangible assets with a determinable life is performed on a periodic basis and when events and circumstances warrant an evaluation. The Company assesses intangible assets with a determinable life for impairment consistent with its policy for assessing other long-lived assets. Goodwill and intangible assets are also reviewed for impairment annually in the fourth quarter or more frequently when changes in circumstances indicate the carrying amount may be impaired, or in the case of finite-lived intangible assets, when the carrying amount may not be recoverable. Such events or changes may include, but are not limited to, a significant deterioration in overall economic conditions, changes in the business climate of the Company's industry, overall performance indicators, a decline in the Company's market capitalization, business reorganization or restructuring or disposal of all or part of a reporting unit. Impairment charges are recognized pursuant to FASB ASC 350-20, “Goodwill.” The Company's goodwill is tested for impairment at a level referred to as the reporting unit. The level at which goodwill is tested for impairment indicates whether the operations within the reporting unit constitute a self-sustaining business. The Company may use both quantitative and qualitative approaches when testing goodwill for impairment. For selected reporting units where the qualitative approach is utilized, a qualitative evaluation of events and circumstances impacting the reporting unit is performed to determine if it is more likely than not that the fair value of the reporting unit exceeds its carrying amount. If that determination is made, no further evaluation is necessary. Otherwise, the Company performs a quantitative impairment test on the reporting unit. For the quantitative approach, the Company uses a combination of the income approach, which uses a discounted cash flow methodology, and the market approach, which uses comparable market multiples 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. The fair value estimates are subjective and sensitive to significant assumptions, such as revenue growth rates, operating margins, the weighted-average cost of capital ("WACC"), and estimated market multiples, of which are affected by expectations of future market or economic conditions. The Company believes that the methodologies, significant assumptions, and weightings used are reasonable and result in appropriate fair values of the reporting units. Given the continued decline in the Company’s results in the Asia-Pacific region and the uncertainty surrounding COVID-19, including the lingering impacts of the Delta variant, the Company concluded that an indicator of impairment was present and conducted an interim quantitative impairment review of its goodwill in the Asia-Pacific reporting unit as of September 30, 2021. The Company reassessed its previous forecasts for this reporting unit which predicted increased sales levels in the second half of 2021. However, actual results were lower than forecast due to extended lockdowns and the postponement of projects within the region. The interim impairment assessment was performed utilizing the same methodologies as the annual assessments discussed above and included revised projections, which are subject to various risks and uncertainties, including forecasted revenues, expenses and cash flows. Based on the interim impairment assessment and annual assessment at October 1, 2021, the Asia-Pacific reporting unit’s fair value exceeded its carrying value by approximately 10 % as compared to 15 % as of October 1, 2020. No indicators of impairment were identified for the Company's other reporting units . The Company re-evaluated the results of its Asia-Pacific region at December 31, 2021 and did not identify additional impairment indicators. The Company will continue to evaluate the results of its Asia-Pacific region and conduct interim testing if additional impairment indicators are present in future quarters. At December 31, 2021, the Asia-Pacific reporting unit's goodwill was $ 7.3 million. The qualitative goodwill impairment test approach was used on the Company's remaining reporting units and there was no evidence that the fair value of each reporting unit would not exceed its carrying value at the October 1, 2021 measurement date. As such, no impairment was recorded at the measurement date. Total combined goodwill for the remaining reporting units was $ 21.3 million as shown in the following table: USA The Americas EMEA Asia-Pacific Total Balance at January 1, 2020 $ 3,078 $ 4,158 $ 13,442 $ 7,162 $ 27,840 Currency translation 0 93 1,007 568 1,668 Balance at December 31, 2020 3,078 4,251 14,449 7,730 29,508 Currency translation 0 ( 7 ) ( 888 ) ( 419 ) ( 1,314 ) Balance at December 31, 2021 $ 3,078 $ 4,244 $ 13,561 $ 7,311 $ 28,194 Impairment assessments inherently involve management judgments regarding a number of assumptions such as those described above. Due to the multiple variables inherent in arriving at the estimates of the reporting unit's fair value, differences in assumptions could have an effect on the estimated fair value of a reporting unit and could result in goodwill impairment charges in a future period. The Company’s only intangible asset with an indefinite life is goodwill. The Company’s goodwill is not deductible for tax purposes.

Fair Value Disclosures [Abstract]
Fair Value of Financial Assets and Liabilities	Note K - Fair Value of Financial Assets and Liabilities The Company measures and records certain assets and liabilities at fair value. A fair value hierarchy is used for those assets and liabilities measured at fair value that distinguishes between assumptions based on market data (observable inputs), and the Company’s assumptions (unobservable inputs). The hierarchy consists of the following three levels: Level 1 Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets. Level 2 Inputs other than Level 1 inputs that are either directly or indirectly observable, which may include: • Quoted prices for similar assets in active markets; • Quoted prices for identical or similar assets or liabilities in inactive markets; • Inputs other than quoted prices that are observable for the asset or liability; and • Inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 3 Inputs to the valuation methodology are unobservable and developed using estimates and assumptions developed by the Company which reflect those that a market participant would use. The following table summarizes the Company’s assets and liabilities, recorded and measured at fair value, in the consolidated balance sheets as of December 31, 2021 and 2020: Description Balance as of Quoted Prices in Active Markets for Identical Assets or Liabilities Significant Other Observable Inputs Significant Unobservable Inputs Assets: Foreign currency forward contracts $ 534 $ 0 $ 534 $ 0 Total Assets $ 534 $ 0 $ 534 $ 0 Liabilities: Supplemental profit sharing plan $ 8,015 $ 0 $ 8,015 $ 0 Total Liabilities $ 8,015 $ 0 $ 8,015 $ 0 Description Balance as of Quoted Prices in Active Markets for Identical Assets or Liabilities Significant Other Observable Inputs Significant Unobservable Inputs Assets: Foreign currency forward contracts $ 359 $ 0 $ 359 $ 0 Total Assets $ 359 $ 0 $ 359 $ 0 Liabilities: Supplemental profit sharing plan $ 7,143 $ 0 $ 7,143 $ 0 Foreign currency forward contracts 56 0 56 0 Total Liabilities $ 7,199 $ 0 $ 7,199 $ 0 The Company operates internationally and enters into intercompany transactions denominated in foreign currencies. Consequently, the Company is subject to market risk arising from exchange rate movements between the dates foreign currency transactions occur and the dates they are settled. The Company currently uses foreign currency forward contracts to reduce the risk related to some of these transactions. These contracts usually have maturities of 90 days or less and generally require an exchange of foreign currencies for U.S. dollars at maturity at rates stated in the contracts. These contracts are not designated as hedging instruments under U.S. GAAP. Accordingly, the changes in the fair value of the foreign currency forward contracts are recognized in each accounting period in “Other operating expense - net” on the Consolidated Statements of Income together with the transaction gain or loss from the related balance sheet position. For the twelve months ended December 31, 2021 and 2020, the Company recognized a net loss of $ 0.7 million and gain of $ 0.4 million, respectively, on foreign currency forward contracts. The gains and losses on foreign currency forward contracts are recorded in Other operating expense, net on the Company’s Statement of Consolidated Income. The Company has a non-qualified Supplemental Profit Sharing Plan for its executives. The liability for this unfunded Supplemental Profit Sharing Plan was $ 8.0 million at December 31, 2021 and $ 7.1 million at December 31, 2020. These amounts are recorded within Other noncurrent liabilities on the Company’s Consolidated Balance Sheets. The Supplemental Profit Sharing Plan allows participants the ability to hypothetically invest their proportionate award into various investment options, which primarily includes mutual funds. The Company credits earnings, gains and losses to the participants’ deferred compensation account balances based on the investments selected by the participants. The Company measures the fair value of the Supplemental Profit Sharing Plan liability using the market values of the participants’ underlying investment accounts. The carrying value of the Company’s current financial instruments, which include cash, cash equivalents and restricted cash, accounts receivable, accounts payable and short-term debt, approximates fair value because of the short-term maturity of these instruments. At December 31, 2021, 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 that are considered to be Level 2 inputs. Based on the analysis performed, the fair value and the carrying value of the Company’s long-term debt are as follows: December 31, 2021 December 31, 2020 Fair Value Carrying Value Fair Value Carrying Value Long-term debt and related current maturities $ 46,577 $ 43,164 $ 38,726 $ 38,549

Revenue from Contract with Customer [Abstract]
Revenue	Note L - Revenue Revenue recognition Sales are recognized when obligations under the terms of the contract are satisfied and control of promised goods or services have transferred to our customers. Control is transferred when the customer has the ability to direct the use of and obtain benefits from the goods or services and is primarily based on shipping terms. Sales are measured as the amount of consideration the Company expects to receive in exchange for transferring products. Net sales include products and shipping and handling charges, net of estimates for product returns. The Company estimates product returns based on historical return rates. Revenue for shipping and handling charges are recognized at the time the products are shipped to, delivered to or picked up by the customer. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as fulfillment costs and are included in cost of goods sold. Payment terms vary by the type and location of the customer and the products or services offered. Generally, the time between when revenue is recognized, and payment is due is not significant. Sales, value added, and other taxes collected concurrent with revenue are excluded from sales. PLP records reductions to sales for returns, and customer and distributor incentives, primarily comprised of rebates, at the time of the initial sale. Rebates are estimated based on sales terms, historical experience, trend analysis, and projected market conditions in the various markets served. Sales commissions are expensed when the amortization period is less than a year and are generally not capitalized as they are typically earned at the completion of the contract when the customer is invoiced or when the customer pays PLP. Sales of products and services varies by segment and are discussed in Note M, "Segment Information". Disaggregated revenue The Company’s revenues by segment and product type are as follows: Year Ended December 31, 2021 Product Type PLP-USA The Americas EMEA Asia-Pacific Consolidated Energy 57 % 68 % 55 % 71 % 61 % Communications 37 % 29 % 39 % 3 % 30 % Special Industries 6 % 3 % 6 % 26 % 9 % Total 100 % 100 % 100 % 100 % 100 % Year Ended December 31, 2020 Product Type PLP-USA The Americas EMEA Asia-Pacific Consolidated Energy 62 % 78 % 57 % 70 % 66 % Communications 32 % 17 % 36 % 4 % 24 % Special Industries 6 % 5 % 7 % 26 % 10 % Total 100 % 100 % 100 % 100 % 100 % Credit losses for receivables The Company maintains an allowance for credit losses for estimated losses resulting from the inability of its customers to make required payments. The Company uses a current expected credit loss model in order to immediately recognize an estimate of credit losses that are expected to occur over the life of the financial instruments, mainly trade receivables. Additionally, the allowance is based upon identified delinquent accounts, customer payment patterns and other analyses of historical data trends. Receivable balances are written off against an allowance for credit losses after a final determination has been made. The change in the allowance for credit losses includes expense and net write-offs, which are identified in the following table: 2021 2020 2019 Allowance for credit losses, beginning of period $ 2,848 $ 3,224 $ 2,652 Additions charged to costs and expenses 931 1,279 1,294 Write-offs ( 435 ) ( 1,527 ) ( 697 ) Foreign exchange and other ( 253 ) ( 128 ) ( 25 ) Allowance for credit losses, end of period $ 3,091 $ 2,848 $ 3,224

Segment Reporting [Abstract]
Segment Information	Note M - Segment Information The Company designs, manufactures and sells hardware employed in the construction and maintenance of telecommunication, energy and other utility networks, data communication products and mounting hardware for solar power applications. Principal products include cable anchoring, control hardware and splice enclosures, which are sold primarily to customers in North and South America, Europe, South Africa and Asia-Pacific. The Company reports its segments in four geographic regions: PLP-USA, The Americas, EMEA (Europe, Middle East & Africa) and Asia-Pacific in accordance with accounting standards codified in Financial Accounting Standards Board “FASB” Accounting Standards Codification “ASC” 280, “Segment Reporting”. Each segment distributes a full range of the Company’s primary products. The PLP-USA segment is comprised of U.S. operations manufacturing the Company’s traditional products primarily supporting domestic energy, telecommunications and solar products. The other three segments, The Americas, EMEA and Asia-Pacific support the Company’s energy, telecommunications, data communication and solar products in each respective geographical region. The segment managers responsible for each region report directly to the Company’s Chief Executive Officer, who is the chief operating decision maker and are accountable for the financial results and performance of their entire segment for which they are responsible. The business components within each segment are managed to maximize the results of the entire company rather than the results of any individual business component of the segment. The amount of each segment’s performance reported to the chief operating decision maker is for purposes of making decisions about allocating resources to the segment and assessing its performance. The Company evaluates segment performance and allocates resources based on several factors primarily based on sales and income from continuing operations, net of tax. The accounting policies of the operating segments are the same as those described in Note A in the Notes to Consolidated Financial Statements. No single customer accounts for more than ten percent of the Company’s consolidated revenue. U.S. net sales for the years ended December 31, 2021, 2020, and 2019 were $ 257.6 million, $ 201.2 million and $ 178.3 million, respectively. U.S. long-lived assets as of December 31, 2021 and 2020 were $ 71.7 million and $ 44.2 million, respectively. The following table presents a summary of the Company’s reportable segments for the years ended December 31, 2021, 2020 and 2019. Financial results for the PLP-USA segment include the elimination of all segments’ intercompany profits in inventory.

Subsequent Events [Abstract]
Subsequent Events	Note P - Subsequent Events On January 2, 2022, Director Emeritus Barbara P. Ruhlman passed away at the age of 89. Barbara was member of the Company’s Board of Directors from 1988 to 2016, at which time she elected to resign and was appointed as the Company’s Director Emeritus. Barbara was the daughter of the Company’s founder, Thomas F. Peterson, and was the mother of the Company’s current Chief Executive Officer, Robert G. Ruhlman. A Company-owned life insurance policy was maintained for Barbara until her death. At December 31, 2021, the cash surrender value was recorded in Other assets on the Company’s Consolidated Balance Sheets. The Company expects to receive cash proceeds from the life insurance policy of approximately $ 7.0 million during the first quarter of 2022 and will be recorded in the Company’s Consolidated Financial Statements upon receipt. On January 4, 2022, the Company acquired all issued and outstanding shares of Maxxweld Conectores Eletricos Ltda. ("Maxxweld"), a Brazilian entity headquartered in Curitiba, Brazil, from its shareholders. Maxxweld designs and manufactures substation connector systems and accessory hardware for high voltage AC systems. The acquisition of Maxxweld will expand and strengthen the Company's operational and technical capabilities in the region while supporting its overall substation strategy. The purchase price was approximately $ 11.2 million as of the closing date. The purchase price is subject to a holdback of approximately $ 1.8 million. To fund the Maxxweld acquisition, the Company borrowed $ 11.2 million on the Facility. On March 1, 2022, the Company acquired all issued and outstanding shares of Holplast, s.r.o (“Holplast”), an entity headquartered in Prostejov, Czech Republic from its shareholder. Holplast specializes in injection molding and will expand the Company’s operational capabilities in the region and strengthen the Company’s position in the global communications market. The purchase price was approximately $ 5.3 million with a holdback of $ 0.8 million. To fund the Holplast acquisition, the Company borrowed $ 4.4 million on its Facility. After the incremental borrowings to fund both the Maxxweld and Holplast, the Company had total borrowings on the Facility of $ 35.1 million as of March 2, 2022. On March 2, 2022, the Company amended its credit facility to increase the capacity from $ 65.0 million to $ 90.0 million. As part of this amendment, the index used to determine the interest rate changed from LIBOR to the Bloomberg Short Term Bank Yield Index (“BSBY”). The interest rate will now be defined as BSBY plus 1.125 % unless the Company’s funded debt to Earnings before Interest, Taxes and Depreciation ratio exceeds 2.25 to 1, at which point the BSBY spread becomes 1.500 %. The amendment also allows the Company to change its rate from BSBY to the Secured Overnight Financing Rate (“SOFR”) at the Company’s discretion. The amendment extended the maturity from June 30, 2024 to March 2, 2026 . All other terms remain the same. The Company does not expect this change in index to have a material impact on the Company’s consolidated financial statements.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Nature of Operations	Nature of Operations Preformed Line Products Company and subsidiaries (the “Company”) is a designer and manufacturer of products and systems employed in the construction and maintenance of overhead and underground networks for the energy, telecommunication, cable operators, data communication and other similar industries. The Company’s primary products support, protect, connect, terminate and secure cables and wires. The Company also provides solar hardware systems and mounting hardware for a variety of solar power applications. The Company’s customers include public and private energy utilities and communication companies, cable operators, governmental agencies, contractors and subcontractors, distributors and value-added resellers. The Company serves its worldwide markets through strategically located domestic and international manufacturing facilities.
Principles of Consolidation and Noncontrolling Interests	Principles of Consolidation and Noncontrolling Interests The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries for which it has a controlling interest. All intercompany accounts and transactions have been eliminated upon consolidation. Noncontrolling interests are presented in the Company’s Consolidated Financial Statements as if parent company investors (controlling interests) and other minority investors (noncontrolling interests) in partially owned subsidiaries have similar economic interests in a single entity. As a result, investments in noncontrolling interests are reported as equity in our Consolidated Financial Statements. Additionally, the Company’s Consolidated Financial Statements include 100 % of a controlled subsidiary’s earnings, rather than only our share. Transactions between the parent company and noncontrolling interests are reported in equity as transactions between stockholders, provided that these transactions do not create a change in control.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash, cash equivalents and restricted cash (“Cash”) are stated at fair value and consist of highly liquid investments with original maturities of three months or less at the time of acquisition. Restricted cash is included on the Cash and cash equivalents on the Company’s Consolidated Balance Sheets.
Accounts Receivable Allowances	Accounts Receivable Allowances The Company maintains an allowance for credit losses for estimated losses resulting from the inability of its customers to make required payments. Prior to the adoption of Financial Accounting Standards Board (“FASB”) ASC 326 “Financial Instruments – Credit Losses", the allowances for uncollectible accounts receivable were based upon the number of days the accounts are past due, the current business and macroeconomic environment, geographic considerations and specific information such as bankruptcy or liquidity issues of its customers. Rather than recognizing losses when they are deemed to be probable, the Company now uses a current expected credit loss model in order to immediately recognize an estimate of credit losses that are expected to occur over the life of the financial instruments, mainly trade receivables. Additionally, the allowance is based upon identified delinquent accounts, customer payment patterns and other analyses of historical data trends. The Company also maintains an allowance for future sales credits related to sales recorded during the year. The estimated allowance is based on historical sales credits issued in the subsequent year related to the prior year and any significant, preapproved open return good authorizations as of the balance sheet date.
Inventories	Inventories The Company uses the last-in, first-out (“LIFO”) method of determining cost for the majority of its material portion of inventories in PLP-USA. All other inventories are determined by the first-in, first-out (“FIFO”) or average cost methods. Inventories are carried at net realizable value. Reserves are maintained for estimated obsolescence or excess inventory based on past usage and future demand.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) 825, “Disclosures about Fair Value of Financial Instruments,” requires disclosures of the fair value of financial instruments. The estimated fair value of financial instruments was principally based on market prices where such prices were available, and when unavailable, fair values were estimated based on market prices of similar instruments.
Property, Plant and Equipment and Depreciation	Property, Plant and Equipment and Depreciation Property, plant, and equipment is recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives. The estimated useful lives used, when purchased new, are: land improvements, ten years ; buildings, forty years ; building improvements, five to forty years ; machinery and equipment, three to ten years ; and aircraft, fifteen years . Appropriate reductions in estimated useful lives are made for property, plant and equipment purchased in connection with an acquisition of a business or in a used condition when purchased.
Long-Lived Assets	Long-Lived Assets The Company records impairment losses on long-lived assets used in operations when events and circumstances indicate that the carrying value of the assets are impaired and the undiscounted future cash flows estimated to be generated by such assets are less than the carrying value. The Company’s cash flows are based on historical results adjusted to reflect the Company’s best estimate of future market and operating conditions. The net carrying value of assets not recoverable is then reduced to fair value. The estimate of fair value represents the Company’s best estimate based on industry trends and reference to market rates and transactions. The Company did not record any impairment to long-lived assets during the years ended December 31, 2021 and 2020.
Goodwill and Other Intangibles	Goodwill and Other Intangibles Goodwill and other intangible assets are generally recoded as a result of a business acquisition. Goodwill represents the excess of purchase price over the fair value of the tangible and identifiable net assets acquired during a business combination and is not subject to amortization but is subject to annual impairment testing. Goodwill is reviewed for impairment annually on October 1 or more frequently when changes in circumstances indicate the carrying amount may be impaired. Such events or changes may include, but are not limited to, a significant deterioration in overall economic conditions, changes in the business climate of the Company's industry, overall performance indicators, a decline in the Company's market capitalization, business reorganization or restructuring or disposal of all or part of a reporting unit. Goodwill is tested for impairment at the reporting unit level, and is based on the net assets for each reporting unit, including goodwill and intangible assets. The Company’s reporting units are equivalent to the reportable operating segments, except for the Americas segment which has two reporting units (Canada and Other Americas). Goodwill is assigned to each reporting unit, as this represents the lowest level that constitutes a business and is the level at which management regularly reviews the operating results. The Other Americas reporting unit does not have any allocated goodwill. Intangible assets with definite lives, consisting primarily of purchased customer relationships, patents, technology, customer backlogs, trademarks and land use rights, are generally amortized over periods from four years to eighty-two years . The Company has no indefinite lived intangible assets other than goodwill. The Company’s intangible assets with finite lives are generally amortized over the period in which the economic benefits of the intangibles are consumed, using either a projected cash flow basis method or the straight-line method. The straight-line method is used in circumstances in which it better reflects the pattern in which the economic benefits of the intangible asset are consumed or otherwise expire compared to using a projected cash flow basis method. An evaluation of the remaining useful life of intangible assets with a determinable life is performed on a periodic basis and when events and circumstances warrant an evaluation. The Company assesses intangible assets with a determinable life for impairment when the carrying amount may not be recoverable, consistent with its policy for assessing other long-lived assets. Approximately $ 0.3 million of impairment charges were recorded in 2021 related to finite-lived intangible assets. The Company may use both quantitative and qualitative approaches when testing goodwill for impairment. A qualitative analysis is performed by assessing certain trends and factors, including projected market outlook and growth rates, forecasted and actual sales and gross profit margins, discount rates and other relevant qualitative factors. These trends and factors are compared to, and based on, the assumptions used in the most recent quantitative analysis performed for each reporting unit to determine if it is more likely than not that the fair value of the reporting unit exceeds its carrying amount. If that determination is made, no further evaluation is necessary. Otherwise, the Company performs a quantitative impairment test on the reporting unit. For the quantitative approach, the Company uses a combination of the income approach, which uses a discounted cash flow methodology, and the market approach, which uses comparable market multiples, 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. The fair value estimates are subjective and sensitive to significant assumptions, such as future cash flows, revenue growth rates, operating margins, the weighted-average cost of capital ("WACC"), and estimated market multiples, of which are affected by expectations of future market or economic conditions. The future cash flows are based on the Company’s long-term operating plan and a terminal value was used to estimate the reporting unit’s cash flows beyond the period covered by the operating plan. The WACC is an estimate of the overall after-tax rate of return required by equity and debt market holders of a business enterprise. The Company believes that the methodologies, significant assumptions, and weightings used are reasonable and result in appropriate fair values of the reporting units. Impairment assessments inherently involve management judgments regarding a number of assumptions such as those described above. Due to the multiple variables inherent in arriving at the estimates of the reporting unit's fair value, differences in assumptions could have an effect on the estimated fair value of a reporting unit and could result in goodwill impairment charges in a future period.
Revenue Recognition	Revenue Recognition Net sales include products and shipping and handling charges, net of estimates for product returns. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products. All revenue is recognized when the Company satisfies the performance obligations under the contract and control of the product is transferred to the customer, primarily based on shipping terms. Revenue for shipping and handling charges are recognized at the time the products are shipped to, delivered to or picked up by the customer. Payment terms vary by the type and location of the customer and the products offered but are generally short-term in nature. The Company estimates product returns based on historical return rates.
Research and Development	Research and Development Research and development costs for new products are expensed as incurred and totaled $ 3.3 million in 2021, $ 2.8 million in 2020 and $ 3.0 million in 2019.
Income Taxes	Income Taxes Income taxes are computed in accordance with the provisions of FASB ASC 740, “Income Taxes” and includes U.S. (federal and state) and foreign income taxes. In the Consolidated Financial Statements, the benefits of a consolidated return have been reflected where such returns have or could be filed based on the entities and jurisdictions included in the financial statements. Uncertain tax positions are recorded in accordance with ASC 740 on the basis of a two-step process whereby (1) the Company determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, the Company recognizes the largest amount of tax benefit that is more than likely than not to be realized upon ultimate settlement with the related tax authority. Deferred taxes are recognized at currently enacted tax rates for temporary differences between the financial reporting and income tax basis of assets and liabilities and operating loss and tax credit carryforwards. The Company establishes a valuation allowance to record deferred tax assets at an amount that is more-likely-than-not to be realized. In the event the Company were to determine that it would be able to realize our deferred tax assets in the future in excess of the recorded amount, an adjustment to the valuation allowance would increase income in the period such determination was made. Likewise, should the Company determine that it would not be able to realize all or part of the net deferred tax assets in the future, an adjustment to the valuation allowance would be charged to expense in the period such determination was made.
Advertising	Advertising Advertising costs are expensed as incurred and totaled $ 1.5 million in 2021, $ 0.3 million in 2020 and $ 1.9 million in 2019.
Foreign Currency Translation	Foreign Currency Translation Asset and liability accounts are translated into U.S. dollars using exchange rates in effect at the date of the Consolidated Balance Sheet. The translation adjustments are recorded in Accumulated other comprehensive income (loss). Revenues and expenses are translated at weighted average exchange rates in effect during the period. Transaction gains and losses arising from exchange rate changes on transactions denominated in a currency other than the functional currency are included in income and expense as incurred. Aggregate transaction losses, including hedge activity, for both years ended December 31, 2021 and 202 0 was $ 1.0 milli on and was $ 1.2 million for the year ended December 31, 2019. Upon sale or substantially complete liquidation of an investment in a foreign entity, the cumulative translation adjustment for that entity is reclassified from Accumulated other comprehensive income (loss) to earnings. Effective July 1, 2018, Argentina was designated as a highly inflationary economy as the projected three-year cumulative inflation rate exceeded 100 %. As such, beginning July 1, 2018, the functional currency for the Company’s Argentina subsidiary became the U.S. dollar. The impact to the Company’s consolidated financial statements for accounting of the Argentina subsidiary under highly inflationary economy rules is not material. Revenue from operations in Argentina was less than 1 % of total consolidated net sales for both years ended December 31, 2021 and 2020 and less than 2 % of consolidated net sales for the year ended December 31, 2019.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates.
Business Combinations	Business Combinations Upon acquisition of a business, the Company uses the income, market or cost approach (or a combination thereof) for the valuation as appropriate. The valuation inputs in these models and analyses are based on market participant assumptions. Market participants are considered to be buyers and sellers unrelated to the Company in the principal or most advantageous market for the asset or liability. In the event there is an earn-out associated with an acquisition, the Company uses a valuation model to measure the contingent consideration, which may include significant assumptions such as revenue projections and discount rates. The Company uses a discounted cash flow model to measure the useful lives of intangible assets. The significant assumptions used to estimate the fair value of the intangible assets include discount rates and certain assumptions that form the basis of future cash flows (such as revenue growth rates, attrition rates, and royalty rates). These assumptions relate to the future performance of the acquired businesses, are forward-looking and could be affected by future economic and market conditions. Fair value estimates are based on a series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. Management values property, plant and equipment using the cost approach supported where available by observable market data, which includes consideration of obsolescence. Acquired inventories are marked to fair value. For certain items, the carrying value is determined to be a reasonable approximation of fair value based on information available to the Company.
Derivative Financial Instruments	Derivative Financial Instruments The Company operates internationally and enters into intercompany transactions denominated in foreign currencies. Consequently, the Company is subject to market risk arising from exchange rate movements between the dates foreign currency transactions occur and the dates they are settled. The Company currently uses foreign currency forward contracts to reduce the risk related to some of these transactions. These contracts usually have maturities of 90 days or less and generally require an exchange of foreign currencies for U.S. dollars at maturity at rates stated in the contracts. These contracts are not designated as hedging instruments under U.S. GAAP. Accordingly, the changes in the fair value of the foreign currency forward contracts are recognized in each accounting period in “Other operating expense - net” on the Consolidated Statements of Income together with the transaction gain or loss from the related balance sheet position. The Company records the contracts at fair value in the Consolidated Balance Sheets. The Company does not hold derivatives for trading purposes.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements On January 1, 2021 , the Company adopted Account Standards Update (ASU) 2019-12 , Income Taxes (ASC 740) – Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC 740 and also clarifies and amends existing guidance to improve consistent application. The adoption of ASU 2019-12 did not have a material impact on the Consolidated financial statements. No other recently issued or effective ASU's had, or are expected to have, a material impact on the Company's results of operations, financial condition or liquidity.
