Accounting Policies [Abstract]
Significant Accounting Policies	NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES The accompanying unaudited consolidated financial statements of Preformed Line Products Company and subsidiaries (the “Company” or “PLPC”) have been prepared in accordance with United States ("U.S.") generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. This Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes included in our Form 10-K for the year ended December 31, 2024 filed on March 13, 2025 with the Securities and Exchange Commission. Management has evaluated subsequent events through the date this Form 10-Q was filed with the Securities and Exchange Commission. The preparation of these consolidated financial statements requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and the accompanying notes. Actual results could differ from these estimates. In the opinion of management, these consolidated financial statements contain all estimates and adjustments, consisting of normal recurring accruals, required to fairly present the financial position, results of operations, and cash flows for the interim periods. Operating results for the three and six months ended June 30, 2025 are not necessarily indicative of the results to be expected for the full-year ending December 31, 2025. 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 the Company’s consolidated financial statements. Additionally, the Company’s consolidated financial statements include 100% of a controlled subsidiary’s earnings, rather than only its 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. Certain prior year amounts have been reclassified to conform to the current year presentation. Recently Adopted or Issued Accounting Pronouncements and Regulations Adopted In November 2023, the FASB issued Accounting Standards Update ("ASU") No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” This ASU enhances reportable segment disclosures on both an annual and interim basis primarily in regards to the disclosure of significant segment expenses that are regularly provided to the chief operating decision maker ("CODM") and included within the reported measure(s) of segment profit or loss. In addition, the ASU requires disclosure, by segment, of other items included in the reported measure(s) of segment profit or loss, including qualitative information describing the composition, nature and type of each item. The ASU also expands disclosure requirements related to the CODM, including how the reported measure(s) of segment profit or loss are used to assess segment performance and allocate resources, the method used to allocate overhead for significant segment expenses and others. Lastly, all current required annual segment reporting disclosures under Topic 280 are now effective for interim periods. The ASU was effective for the Company's 2024 fiscal year and interim periods beginning with the quarter ended March 31, 2025. The adoption of this new standard did not have a material impact on the consolidated financial statements, other than the updated segment disclosures included within Note 13, "Segment Information". Not Yet Adopted In December 2023, the FASB issued Accounting Standards Update No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” This ASU enhances income tax disclosures by providing information to better assess how an entity's operations, related tax risks, tax planning and operational opportunities affect its tax rate and prospects for future cash flows. This ASU requires additional disclosures to the annual effective tax rate reconciliation including specific categories and further disaggregated reconciling items that meet the quantitative threshold. Additionally, the ASU requires disclosures relating to income tax expense and payments made to federal, state, local and foreign jurisdictions. This ASU is effective for fiscal years beginning after December 15, 2024. The Company is evaluating the impact of adopting this ASU and expects the standard will only impact its income tax disclosures with no material impact to the consolidated financial statements. In November 2024, the FASB issued Accounting Standards Update No. 2024-03, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” This ASU improves disclosures about a public business entity’s expenses and addresses requests from investors for more detailed information about the types of expenses commonly presented in expense captions. Coupled with recent standards that enhanced the disaggregation of revenue and income tax information, the disaggregated expense information required by the amendments in this ASU will enable investors to better understand the major components of an entity’s income statement. This ASU is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is evaluating the impact of adopting this ASU. New Regulations On July 4, 2025, the One Big Beautiful Bill Act ("OBBBA") was enacted in the U.S. The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain businesses. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The Company is currently assessing its impact on the consolidated financial statements.
