Accounting Policies [Abstract] |
Basis of Presentation | The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The year-end consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. In the opinion of management, all estimates and adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2025 are not necessarily indicative of the results that may be expected for the year ending December 31, 2025. This Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and footnotes thereto included in L.B. Foster Company’s Annual Report on Form 10-K for the year ended December 31, 2024. In this Quarterly Report on Form 10-Q, references to “we,” “us,” “our,” and the “Company” refer collectively to L.B. Foster Company and its consolidated subsidiaries.
Recently Issued Accounting Standards | Recently Issued Accounting Standards In December 2023, the FASB issued Accounting Standards Update 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 requires entities to disclose additional information with respect to the effective tax rate reconciliation and disaggregation of income tax expense and income taxes paid by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company does not expect the adoption of ASU 2023-09 to have an impact to its consolidated financial condition, results of operations, and cash flows other than its disclosures. In November 2024, the FASB issued Accounting Standards Update 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40) (“ASU 2024-03”), which requires entities to provide more detailed disaggregation of expenses in the income statement, focusing on the nature of the expenses rather than their function. The new disclosures will require public business entities to disclose in the notes to the financial statements, at each interim and annual reporting period, specific information about certain costs and expenses, including purchases of inventory, employee compensation, depreciation, and intangible asset amortization included in each expense caption presented on the face of the income statement, and the total amount of an entity's selling expenses. The amendments are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, and may be applied either prospectively or retrospectively. Early adoption is permitted. The Company is currently evaluating the impact of adopting this guidance on the consolidated financial statements. In September 2025, the FASB issued Accounting Standards Update 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) (“ASU 2025-06”), which provides targeted improvements related to the accounting for costs incurred in the development of internal-use software. The amendment replaces the previous stage-based model with clearer guidance on capitalization thresholds and implementation costs. The amendments are effective for annual periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. Early adoption is permitted as of the beginning of an annual reporting period. The Company is currently evaluating the impact of adopting this guidance on the consolidated financial statements and related disclosures.
