Organization Consolidation And Presentation Of Financial Statements [Abstract]

NOTE A – BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements of Preformed Line Products Company and subsidiaries (the “Company” or “PLPC”) have been prepared in accordance with United States of America (U.S.) generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X.

The preparation of these consolidated financial statements requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and the accompanying notes. Actual results could differ from these estimates. In the opinion of management, these consolidated financial statements contain all estimates and adjustments, consisting of normal recurring accruals, required to fairly present the financial position, results of operations, and cash flows for the interim periods. Operating results for the three and nine months ended September 30, 2021 are not necessarily indicative of the results to be expected for the full-year ending December 31, 2021.

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.

The Consolidated Balance Sheet at December 31, 2020 has been derived from the audited consolidated financial statements but does not include all of the information and notes required by U.S. GAAP for complete financial statements. For further information, refer to the consolidated financial statements and notes to consolidated financial statements included in the Company’s 2020 Annual Report on Form 10-K filed on March 5, 2021 with the Securities and Exchange Commission.
