The accompanying unaudited consolidated financial statements include all the accounts of the holding company’s wholly owned subsidiaries, Vitamin Cottage Natural Food Markets, Inc.

The Company has one reporting segment: natural and organic retail stores.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of financial statements in conformity with GAAP 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 reporting period. Management reviews its estimates on an ongoing basis, including those related to valuation of inventories, useful lives of long-lived assets for depreciation and amortization, impairment of finite-lived intangible assets, long-lived assets, and goodwill, lease assumptions, allowances for self-insurance reserves, deferred tax assets and liabilities, and litigation based on currently available information. Changes in facts and circumstances may result in revised estimates and actual results could differ from those estimates.

On December 15, 2022, the Company amended the Credit Facility (as defined in Note 5 below) to, among other things, replace the LIBOR-based interest rate benchmark provisions with interest rate benchmark provisions based on the Secured Overnight Financing Rate (SOFR).

ASU 2019-10, issued in November 2019, delayed the effective date of ASU 2016-13 for smaller reporting companies such as the Company. The Company adopted ASU 2016-13 effective October 1, 2023 by recognizing the cumulative effect of initially applying the new credit loss standard as an adjustment to the opening balance of retained earnings.

In addition, the provisions enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements.

The ASU 2023-09 provisions require entities, on an annual basis, to disclose specific categories in the rate reconciliation and provide additional information for reconciling items equal to or greater than 5% of the statutory income tax rate amount. ASU 2023-09 also requires that entities disclose on an annual basis information about the amount of income taxes paid disaggregated by federal, state, and foreign taxes and disaggregated by individual jurisdictions in which income taxes paid is equal to or greater than 5% of total income taxes paid. In addition, ASU 2023-09 eliminates some disclosures relating to estimates of the change in unrecognized tax benefits reasonably possible within 12 months. The provisions of ASU 2023-09 will be effective for the Company’s fiscal year ending September 30, 2026. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of these provisions will have on its consolidated financial statements. No other new accounting pronouncements issued or effective during the three months ended June 30, 2024 had, or are expected to have, a material impact on the Company’s consolidated financial statements.
