Accounting Policies [Abstract] |
Basis of Accounting, Policy [Policy Text Block] | Basis of Presentation and Summary of Significant Accounting Policies The unaudited consolidated financial statements of Harvard Bioscience, Inc. and its wholly-owned subsidiaries (collectively, the “Company”) as of March 31, 2024 and for the three months ended March 31, 2024 and 2023, have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. The December 31, 2023 consolidated balance sheet was derived from audited financial statements but does not include all disclosures required by U.S. GAAP. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023. In the opinion of management, all adjustments, which include normal recurring adjustments necessary to present a fair statement of financial position as of March 31, 2024, results of operations and comprehensive income (loss) and cash flows for the three months ended March 31, 2024 and 2023, as applicable, have been made. The results of operations for the three months ended March 31, 2024, are not necessarily indicative of the operating results for the full fiscal year or any future periods. The accounting policies underlying the accompanying unaudited consolidated financial statements are set forth in Note 2 to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. There have been no material changes in the Company’s significant accounting policies during the three months ended March 31, 2024.
Use of Estimates, Policy [Policy Text Block] | Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires the use of management estimates. Such estimates include the determination and establishment of certain accruals and provisions, including those for income taxes, credit losses on receivables, and defined benefit pension obligations. Estimates are also required to evaluate the value for inventories reported at lower of cost or net realizable value, stock-based compensation expense, and the recoverability of long-lived and intangible assets, including goodwill. On an ongoing basis, the Company reviews its estimates based upon currently available information. Actual results could differ materially from those estimates.
Other Operating Expenses [Policy Text Block] | Other Operating Expenses Other operating expenses for the three months ended March 31, 2024 included a fee of $0.5 million in connection with the receipt of employee retention credits (See Note 5) and an estimated loss of $0.5 million related to an unclaimed property audit (See Note 13).
New Accounting Pronouncements, Policy [Policy Text Block] | Recently Issued Accounting Pronouncements Yet to Be Adopted In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax, which enhances disclosures related to the effective tax rate reconciliation, income taxes paid, as well as other disclosures. The new standard impacts footnote disclosures and is effective for the Company’s annual financial statements for the year ended December 31, 2025. The Company is currently evaluating the potential impact of adopting ASU No. 2023-09 will have on the disclosures in its consolidated financial statements.
