Accounting Policies [Abstract] |
Basis of Presentation | The accompanying condensed consolidated financial statements have been prepared by CTS Corporation (“CTS”, “we”, “our”, “us” or the “Company”), without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been omitted pursuant to such rules and regulations. The unaudited condensed consolidated financial statements should be read in conjunction with the financial statements, notes thereto, and other information included in the Company’s Annual Report on Form 10‑K for the year ended December 31, 2025. The accompanying unaudited condensed consolidated financial statements reflect, in the opinion of management, all adjustments (consisting of normal recurring items) necessary for a fair statement, in all material respects, of the financial position and results of operations for the periods presented. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported period. Actual results could differ materially from those estimates. The results of operations for the interim periods are not necessarily indicative of the results for the entire year. During the three months ended March 31, 2026, the Company entered into a new agreement for the purchase of platinum used in the manufacturing process of certain products. The purchased platinum is presented in Property, plant and equipment, net on the Consolidated Balance Sheets. The platinum is not depreciated because it has very low physical loss and is repeatedly reclaimed and reused in our manufacturing process over a very long useful life. The physical loss of platinum in the manufacturing and reclamation process is treated as depletion and these losses are accounted for as a period expense based on actual units lost. Platinum is reviewed for impairment as part of our assessment of long-lived assets. This review considers all our platinum that is either in place in the production process; in reclamation, fabrication, or refinement in anticipation of re-use; or awaiting use to support increased capacity. Platinum is only acquired to support our operations and is not held for trading purposes. There have been no other material changes in the Company’s significant accounting policies as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. Accounting pronouncements recently adopted ASU No. 2025-05, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets” In July 2025, the FASB issued ASU 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which allows for a practical expedient election to assume that current conditions as of the balance sheet date do not change for the remaining life of the asset in the development of a reasonable and supportable forecast as part of estimating expected credit losses. The Company adopted ASU 2025-05 effective January 1, 2026 on a prospective basis and elected the practical expedient for the calculation of current expected credit losses. The adoption did not have a material effect on the Company’s consolidated financial statements.
Accounting Pronouncements Recently Adopted | Recently issued accounting pronouncements not yet adopted ASU No. 2024-03, “Income Statement (Subtopic 220-40): Disaggregation of Income Statement Expenses” In November 2024, the FASB issued ASU 2024-03, Income Statement (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires additional information about certain expenses in the notes to the financial statements. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, with early adoption permitted. The standard can be applied either prospectively or retrospectively. The Company is currently evaluating the impact of adopting ASU 2024-03. ASU No. 2025-06, “Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software” In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which is intended to improve the operability and application of guidance related to capitalized software development costs. ASU 2025-06 is effective for fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2025-06.
