Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation References in this Quarterly Report on Form 10-Q to “Interface,” “the Company,” “we,” “our,” “ours” and “us” refer to Interface, Inc. and its subsidiaries or any of them, unless the context requires otherwise. As contemplated by the Securities and Exchange Commission (the “Commission”) instructions to Form 10-Q, the following footnotes have been condensed and, therefore, do not contain all disclosures required in connection with annual financial statements. Reference should be made to the Company’s year-end financial statements and notes thereto contained in its Annual Report on Form 10-K for the fiscal year ended December 29, 2024, as filed with the Commission. In the opinion of management, the unaudited financial information prepared by the Company and included in this report contains all adjustments necessary for a fair presentation of the results for the interim periods. All such adjustments are of a normal recurring nature unless otherwise disclosed. Nevertheless, the results shown for interim periods are not necessarily indicative of results to be expected for the full year. The December 29, 2024, consolidated condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States (“GAAP”). The nine-month periods ended September 28, 2025 and September 29, 2024 both include 39 weeks. The three-month periods ended September 28, 2025 and September 29, 2024 both include 13 weeks. Risks and Uncertainties Global economic challenges including but not limited to the impacts of government-imposed tariffs and retaliatory tariffs, inflation, supply chain disruptions, the Russia-Ukraine war and the conflicts in the Middle East, and slow market conditions in certain parts of the globe could cause economic uncertainty and volatility. The Company considered these impacts and subsequent general uncertainties and volatility in the global economy on the assumptions and estimates used herein. These uncertainties could result in a future material adverse effect to the amounts reported within the Company’s consolidated condensed financial statements if actual results differ from these estimates. Recently Issued Accounting Pronouncements – Not Yet Adopted In September 2025, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2025-06 - “Intangibles - Goodwill and Other Internal Use Software (Topic 350-40)”. This ASU amends the accounting for internal-use software costs by removing reference to prescriptive and sequential software development stages used to evaluate capitalizable costs. The ASU requires entities to consider whether significant uncertainties associated with development activities have been resolved prior to capitalization of software costs and aligns disclosure requirements with ASC 360, “Property, Plant, and Equipment”. The new guidance in ASU 2025-06 is effective for annual periods beginning after December 15, 2027, and interim periods within those annual reporting periods, and may be applied prospectively, retrospectively, or using a modified retrospective approach. Early adoption is permitted. The Company is currently evaluating the impact of this ASU to its consolidated financial statements. In November 2024, the FASB issued ASU 2024-03, “Income Statement Reporting - Comprehensive Income - Expense Disaggregation (Topic 220-40)”. This ASU requires public entities to provide additional footnote disclosures to disaggregate the cost and expense line items presented in the income statement into specific categories including (a) purchases of inventory; (b) employee compensation; (c) depreciation; and (d) intangible asset amortization. The ASU also requires qualitative disclosure of other relevant expense categories not separately disclosed, the total amount of selling expenses, and the definition of selling expenses in annual reporting periods. The new guidance in ASU 2024-03 is effective for annual periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of this ASU to its consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”. This ASU requires public entities on an annual basis to disclose a rate reconciliation with explicit categories, as outlined in the ASU, and requires additional disclosures for reconciling items that meet certain quantitative thresholds. Other disclosures include disaggregation of income taxes paid, pre-tax income, and income tax expense. The new guidance is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments in this ASU should be applied on a prospective basis, however retrospective application is permitted. The Company is currently assessing the updated guidance; however, it is not expected to have a material impact to its consolidated financial statements.
