Accounting Policies [Abstract] |
Consolidation, Policy [Policy Text Block] | Principles of Consolidation. The Consolidated Financial Statements include the accounts of the Company and its subsidiaries: USBERM, USCAN and U.S. Global Indices, LLC. There are two primary consolidation models in U.S. GAAP, the variable interest entity (“VIE”) and voting interest entity models. The Company’s evaluation for consolidation includes whether entities in which it has an interest or from which it receives fees are VIEs and whether the Company is the primary beneficiary of any VIEs identified in its analysis. A VIE is an entity in which either (a) the equity investment at risk is not sufficient to permit the entity to finance its own activities without additional financial support or (b) the group of holders of the equity investment at risk lacks certain characteristics of a controlling financial interest. The primary beneficiary is the entity that has the obligation to absorb a majority of the expected losses or the right to receive the majority of the residual returns and consolidates the VIE on the basis of having a controlling financial interest. The Company holds variable interests in certain funds it advises, specifically, certain funds in USGIF and certain U.S. Global ETF clients. However, it is not deemed to be the primary beneficiary of these funds. The Company’s interests in these VIEs consist of the Company’s direct ownership therein and any fees earned but uncollected. In the ordinary course of business, the Company may choose to waive certain fees or assume operating expenses of the funds it advises for competitive, regulatory or contractual reasons (see Note 4 for information regarding fee waivers). The Company has not provided financial support to any of these entities outside the ordinary course of business. The Company’s risk of loss with respect to these VIEs is limited to the carrying value of its investments in, and fees receivable from, the entities. The Company is not deemed to be the primary beneficiary because it does not have the obligation to absorb a majority of the expected losses or the right to receive the majority of the residual returns. The Company does not consolidate these VIEs because it is not the primary beneficiary. The Company’s total exposure to unconsolidated VIEs, consisting of the carrying value of investment securities and receivables for fees, was $11.0 million and $10.5 million at June 30, 2025, and 2024, respectively. The carrying ﻿amount of assets and liabilities recognized in the Consolidated Balance Sheets related to the Company's interests in these non-consolidated VIEs were as follows:
| Carrying Value and Maximum Exposure to Loss
(dollars in thousands) | June 30, 2025 |  | June 30, 2024
Investments in trading securities at fair value, current | $ | 9,692 |  | $ | 9,644
Investments in trading securities at fair value, non-current |  | 872 |  |  | 806
Other receivables |  | 439 |  |  | 28
Total VIE assets, maximum exposure to loss | $ | 11,003 |  | $ | 10,478
Since the Company is not the primary beneficiary of the funds it advises, the Company evaluated if it should consolidate under the voting interest entity model. Under the voting interest model, for legal entities other than partnerships, the usual condition for control is ownership, directly or indirectly, of more than 50 percent of the outstanding voting shares over an entity. The Company does not have control of any of the funds it advises; therefore, the Company does not consolidate any of these funds. All significant intercompany balances and transactions have been eliminated in consolidation. Certain amounts have been reclassified for comparative purposes.
Cash and Cash Equivalents, Policy [Policy Text Block] | Cash and Cash Equivalents. Cash and cash equivalents include highly liquid investments with original maturities of three months or less.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block] | Restricted Cash. Restricted cash represents cash invested in a money market account as collateral for credit facilities that is not available for general corporate use.
Investment, Policy [Policy Text Block] | Investments. The Company records security transactions on trade date. Realized gains (losses) from security transactions are calculated on a first-in/first-out cost basis, unless otherwise identifiable, and are recorded in earnings on the date of sale. Investments in Equity Securities. Equity securities are generally carried at fair value on the Consolidated Balance Sheets with changes in the fair value recorded through earnings within net investment income (loss). Investments in Debt Securities. The Company classifies debt investments based on the Company’s intent to sell the security or its intent and ability to hold the debt security to maturity. Debt securities classified as trading are acquired with the intent to sell in the near term and are carried at fair value with changes reported in earnings. Held-to-maturity debt securities are purchased with the intent and ability to hold until maturity and are measured at amortized cost. All other debt securities are classified as available-for-sale and are carried at fair value, and changes in unrealized gains and losses are reported net of tax in accumulated other comprehensive income (loss), except for declines in fair value determined to be a result of credit loss, which are reported in earnings. Upon the sale or other disposition of an available-for-sale security, the Company reclassifies the gain or loss on the security from accumulated other comprehensive income (loss) to net investment income (loss). Both available-for-sale and held-to-maturity debt securities are subject to an allowance for credit losses. Allowance for Credit Losses (Held-to-Maturity Debt Securities). For held-to-maturity debt securities, the Company is required to utilize the CECL methodology to estimate expected credit losses. Securities are evaluated on an individual basis. The individual assessment and determination of expected credit losses is generally based on the discounted cash flow method. Under the discounted cash flow method, the allowance for credit losses reflects the difference between the amortized cost basis and the present value of the expected cash flows. The Company adjusts the discount rate utilized to determine the present value of the expected cash flows quarterly for subsequent fluctuations in market interest rates. Changes in the present value attributable to the passage of time are those solely due to changes in the present value of the expected cash flows as the instrument approaches maturity rather than expectations of cash flow timing or amounts and are included in interest income within net investment income (loss) on the Consolidated Statements of Operations. Changes in the allowance attributable to expectations of cash flow timing or amounts are recorded as a provision (or release) for credit losses and are included within other income (loss) on the Consolidated Statements of Operations. Held-to-maturity debt securities, or portions thereof, are charged against the allowance when management believes the uncollectible status of a held-to-maturity security is confirmed. Accrued interest receivable, if any, is included within accounts and other receivables on the Consolidated Balance Sheets. Accrued interest receivable is excluded from the allowance for credit losses. For more information about held-to-maturity debt securities, see Note 3, Investments. Allowance for Credit Losses (Available-for-Sale Debt Securities). The impairment model for available-for-sale debt securities differs from the CECL methodology applied for held-to-maturity debt securities because available-for-sale debt securities are measured at fair value rather than amortized cost. For available-for-sale debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or whether it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either criterion is met, the security’s amortized cost basis is written down to fair value through earnings. If neither criterion is met, the Company evaluates whether the decline in fair value is attributable to credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the security's credit rating by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security is compared to its amortized cost basis. If the present value of expected cash flows is less than the amortized cost basis, a credit loss is deemed to exist, and an allowance for credit losses is recorded, limited to the amount by which fair value is less than the amortized cost basis. Any remaining unrealized loss not recorded through an allowance for credit losses is recognized in other comprehensive income (loss). Changes in the allowance are recorded as a provision (or release) for credit losses and are included within other income (loss) on the Consolidated Statements of Operations. Losses are charged against the allowance when management determines that the uncollectible status of an available-for-sale security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Accrued interest receivable, if any, is included within accounts and other receivables on the Consolidated Balance Sheets and is excluded from the allowance for credit losses. See Note 3, Investments, for more information about available-for-sale debt securities. Credit Quality Indicators. The Company monitors the credit quality of debt securities through credit ratings from various rating agencies. Credit ratings express opinions about the credit quality of a security and are utilized by the Company to make informed decisions. Investment grade securities are rated BBB-/Baa3 or higher and generally considered by the rating agencies and market participants to be of low credit risk. Conversely, securities rated below investment grade are considered to have distinctively higher credit risk than investment grade securities. For securities without credit ratings, the Company utilizes other financial information indicating the financial health of the underlying organization. Embedded derivatives. The Company does not use derivatives for trading, speculation, or hedging exposures. Certain financial instruments in which the Company invests contain both a derivative and a non-derivative component. In such cases, the derivative component is referred to as an embedded derivative, with the non-derivative component representing the host contract. If the economic characteristics and risks of the embedded derivative are not closely related to those of the host contract, and changes in the fair value of the host contact itself are not recorded through earnings within net investment income (loss), the embedded derivative is bifurcated and carried at fair value. Changes in its fair value are recorded through earnings within net investment income (loss) on the Consolidated Statements of Operations and included as an adjustment to reconcile net income (loss) to net cash provided by operating activities on the Consolidated Statements of Cash Flows. The host contract continues to be accounted for in accordance with the applicable accounting standard. The embedded derivative and the related host contract represent a single legal contract and are presented together on the Consolidated Balance Sheets and in the tables within Note 3, Investments, unless otherwise indicated. Other Investments. Other investments consist of equity investments in entities over which the Company is unable to exercise significant influence and which do not have readily determinable fair values. The Company generally elects to value these investments using the measurement alternative, under which such securities are measured at cost, less impairment, if any. If the Company identifies observable price changes for identical or similar securities of the same issuer, the equity security is measured at fair value as of the date the observable transaction occurred, with such changes recorded in net investment income (loss). The Company reassesses at each reporting period whether the equity investment's fair value becomes readily determinable, and if so, the Company subsequently elects to measure the equity investment at fair value.
Fair Value of Financial Instruments, Policy [Policy Text Block] | Fair Value of Financial Instruments. The financial instruments of the Company are reported on the Consolidated Balance Sheets at market or fair values or at carrying amounts that approximate fair values.
Accounts Receivable [Policy Text Block] | Receivables and Allowance for Credit Losses. Accounts and other receivables consist primarily of advisory and other fees owed to the Company by clients. The Company records an expense based on a forward-looking current expected credit loss model to maintain an allowance for credit losses. When determining the allowance for receivables, the probability of recoverability of the receivable based on past experience, taking into account current collection trends and general economic factors, including bankruptcy rates, is considered. The Company also considers future economic trends to estimate expected credit losses over the lifetime of the asset. Credit risks are assessed based on historical write-offs, net of recoveries, as well as an analysis of the aged accounts receivable balances with allowances generally increasing as the receivable ages. Accounts receivable may be fully reserved for when specific collection issues are known to exist, such as pending bankruptcies. Due to the short-term nature, the Company had no allowance for credit losses related to receivables as of as of June 30, 2025, or 2024.
Property, Plant and Equipment, Policy [Policy Text Block] | Property and Equipment. Fixed assets are recorded at cost. Depreciation for fixed assets is recorded using the straight-line method over the estimated useful life of each asset as follows: furniture and equipment are depreciated over 3 to 10 years, and the building and related improvements are depreciated over 14 to 40 years.
Lessee, Leases [Policy Text Block] | Leases. The Company leases equipment under various leasing arrangements. Leases may be classified as either financing leases or operating leases, as appropriate. The Company determines if a contract is a lease or contains a lease at inception. The Company accounts for lease and non-lease components as a single component for its leases. The Company elected the short-term lease exception for leases with an initial term of 12 months or less. Consequently, such leases are not recorded on the Consolidated Balance Sheets. The Company’s lease terms include options to extend or terminate the lease when it is reasonably certain they will be exercised or not, respectively. Fixed lease payments are included in right of use (“ROU”) assets and lease liabilities within other assets and liabilities, respectively, on the Consolidated Balance Sheets. ROU assets and lease liabilities are recognized based on the present value of the future lease payments over the lease term at the commencement date using the Company’s incremental borrowing rate as the discount rate. Fixed lease payments made over the lease term are recorded as lease expense on a straight-line basis. Variable lease payments based on usage, changes in an index or market rate are expensed as incurred. For new leases, the discount rates are based on the entire noncancelable lease term. The Company is the lessor of certain areas of its owned office building under operating leases. The Company determines if a contract is a lease or contains a lease at inception. The Company elected not to separate lease and related non-lease components and account for the combined component as an operating lease.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block] | Impairment of Long-Lived Assets. The Company reviews property and equipment and other long-lived assets for impairment whenever events or changes in business circumstances indicate the net book values of the assets may not be recoverable. Impairment is indicated when the assets’ net book value is less than the fair value of the asset. If this occurs, an impairment loss is recognized for the difference between the fair value and net book value. Factors that indicate potential impairment include: a significant decrease in the market value of the asset or a significant change in the asset’s physical condition or use. No impairments of long-lived assets were recorded during the years included in these financial statements.
Stockholders' Equity, Policy [Policy Text Block] | Treasury Stock. Treasury stock purchases are accounted for under the cost method. The subsequent issuances of these shares are accounted for based on their weighted-average cost basis.
Share-Based Payment Arrangement [Policy Text Block] | Share-Based Compensation. Share-based compensation expense is measured at the grant date based on the fair value of the award, and the cost is recognized as expense ratably over the award’s vesting period. Forfeitures are recognized as they occur.
Income Tax, Policy [Policy Text Block] | Income Taxes. Provisions for income taxes include deferred taxes for temporary differences in the bases of assets and liabilities for financial and tax purposes, resulting from the use of the liability method of accounting for income taxes. The liability method requires that deferred tax assets be reduced by a valuation allowance in cases where it is more likely than not that the deferred tax assets will not be realized. The Company accounts for income taxes in accordance with ASC 740, Income Taxes. The Company’s policy is to recognize interest and penalties related to uncertain tax positions in income tax expense. The Company also maintains a reserve for uncertain tax positions. The Company evaluates tax positions taken or expected to be taken in a tax return for recognition in the Consolidated Financial Statements. Prior to recording the related tax benefit in the Consolidated Financial Statements, the Company must conclude that tax positions will be more-likely-than-not to be sustained, assuming those positions will be examined by taxing authorities with full knowledge of all relevant information. The benefit recognized in the Consolidated Financial Statements is the amount the Company expects to realize after examination by taxing authorities. If a tax position drops below the more-likely-than-not standard, the benefit can no longer be recognized. Assumptions, judgment, and the use of estimates are required in determining if the more-likely-than-not standard has been met when developing the provision for income taxes and in determining the expected benefit. A change in the assessment of the more-likely-than-not standard could materially impact the Company’s results of operations or financial position. See Note 12 for further discussion of the Company’s reserve for uncertain tax positions. The Company has elected to treat the global intangible low-taxed income (GILTI) tax as a period expense. The Company also elected to use the tax law ordering approach when assessing the realization of net operating losses related to GILTI.
Revenue [Policy Text Block] | Revenue Recognition. The Company’s operating revenue is earned from investment advisory and administrative services provided to clients. Each distinct service promised in the agreements is considered a performance obligation and is the basis for determining when revenue is recognized. The fees are allocated to each distinct performance obligation and revenue is recognized when, or as, promises are satisfied. The consideration for services is generally variable and included in net revenues when it is improbable that a significant reversal could occur in the future. The timing of when clients are billed and related payment received varies in accordance with agreed-upon contractual terms. For current agreements, billing occurs after the Company has recognized revenue which results in accounts receivable and revenue. Investment Advisory Fees. The investment advisory agreements have a single performance obligation, since the promised services are not separately identifiable from other promises in the agreements and, therefore, are not distinct. Investment advisory fees consist of a base fee. During fiscal 2025 and 2024, investment advisory fees also included a performance fee component, as applicable. Base investment advisory fees are recognized as the services are performed over time and are based upon agreed-upon percentages of average assets under management (“AAUM”), depending on contractual terms. These fees are received in cash after the end of each monthly period within 30 days. Investment advisory fees are affected by changes in assets under management, including market appreciation or depreciation, foreign exchange translation, and net inflows or outflows. Investment advisory fees are reported net of fee waivers. Performance Fees. USGI received or paid investment advisory performance fees for certain funds. Performance fees for the equity funds within USGIF were fulcrum fees consisting of a 0.25 percent upwards or downwards adjustment of the base investment advisory fees when there was a 5 percent difference between a fund’s performance and that of its benchmark index over the prior rolling 12 months. Performance fees were recorded when it was determined that they were no longer probable of significant reversal. These fees were received in cash or paid in cash after the end of each monthly period within 30 days. Performance fees were affected by changes in fund performance, benchmark index performance, and assets under management. Performance fees began to be phased out during the fourth quarter of fiscal 2024 and ceased during the fourth quarter of fiscal 2025. During the phase-out period, the adjustment for the performance fee could only be adjusted downward. Administrative Services Fees. The administrative services agreement has a single performance obligation, since the promised services are not separately identifiable from other promises in the agreement and, therefore, are not distinct. Administrative services fees are recognized as the services are performed over time and are based upon agreed-upon percentages of AAUM. These fees are received in cash after the end of each monthly period within 30 days. Administrative services fees are affected by changes in assets under management, including market appreciation or depreciation, foreign exchange translation, and net inflows or outflows. Administrative services fees are reported net of fee waivers. Fee Waivers. For certain clients, the Company has agreed to contractually limit the expenses or voluntarily waive or reduce its fees and/or agreed to pay expenses for funds. These fee waivers are deemed to be a reduction of the transaction price and are reported as a reduction of investment advisory fees and/or administrative services fees. These fees are paid in cash after the end of each monthly period within 30 days.
Dividends and Interest [Policy Text Block] | Dividends and Interest. Dividends are recorded on the ex-dividend date, and interest income is recorded on an accrual basis. Debt investments are placed on a non-accrual status when they are past due 180 days or more as to contractual obligations or when other circumstances indicate that collection is not probable. When a debt investment is placed on a non-accrual status, any interest accrued but not received is reversed against interest income. Any discount between the cost and the principal amount of debt investments is amortized to interest income using the effective interest method. When the discounted cash flow method is utilized to estimate expected credit losses for held-to-maturity debt securities, any changes in the allowance for credit losses that are attributable to the passage of time are recognized in interest income. Both dividends and interest income are included within net investment income (loss) on the Consolidated Statements of Operations.
Advertising Cost [Policy Text Block] | Advertising Costs. The Company expenses advertising costs as they are incurred. The Company is reimbursed for certain advertising expenses related to USGIF from the distributor for USGIF.
Foreign Currency Transactions and Translations Policy [Policy Text Block] | Foreign Exchange. The balance sheets of certain foreign subsidiaries of the Company and certain foreign-denominated investment products are translated at the current exchange rate as of the end of the accounting period and the related income or loss is translated at the average exchange rate in effect during the period. Net exchange gains and losses resulting from balance sheet translations of foreign subsidiaries are excluded from income and are recorded in accumulated other comprehensive income (loss) on the Consolidated Balance Sheets. Net exchange gains and losses resulting from income or loss translations are included in income and are recorded in net investment income (loss) on the Consolidated Statements of Operations. Investment transactions denominated in foreign currencies are converted to U.S. dollars using the exchange rate on the date of the transaction and any related gain or loss is included in net investment income (loss) on the Consolidated Statements of Operations.
Use of Estimates, Policy [Policy Text Block] | Use of Estimates. The preparation of the Consolidated Financial Statements in conformity with generally accepted accounting principles requires the Company to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Actual results could differ from these estimates.
Earnings Per Share, Policy [Policy Text Block] | Earnings Per Share. The Company computes and presents earnings per share in accordance with ASC 260, Earnings Per Share. Basic earnings per share (“EPS”) excludes dilution and is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution of EPS that could occur if options to issue common stock were exercised. The Company has two classes of common stock with outstanding shares. Both classes share equally in dividend and liquidation preferences.
Comprehensive Income, Policy [Policy Text Block] | Accumulated Other Comprehensive Income (Loss). Accumulated other comprehensive income (loss), net of tax, is reported in the Consolidated Balance Sheets and the Consolidated Statements of Shareholders’ Equity and includes any unrealized gains and losses on debt securities classified as available-for-sale and foreign currency translation adjustments.
New Accounting Pronouncements, Policy [Policy Text Block] | Adoption of New Accounting Standard In June 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, and has subsequently issued several amendments (collectively, “ASU 2016-13”). ASU 2016-13 adds to U.S. GAAP an impairment model (known as the current expected credit loss model, or "CECL") that is based on expected losses rather than incurred losses for most financial assets and certain other instruments. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses. It also modifies the impairment model for available-for-sale debt securities; the concept of "other-than-temporary" impairment was replaced by a determination of whether any impairment is a result of a credit loss or other factors. To adopt the standard, entities are required to make a cumulative-effect adjustment to beginning retained earnings as of the beginning of the fiscal year in which the guidance is effective. The Company adopted the standard using the modified-retrospective approach for all financial assets measured at amortized cost on July 1, 2023, and recognized an initial allowance for credit losses of $232,000 for one held-to-maturity debt security. The cumulative-effect adjustment to beginning retained earnings, net of the related tax effect, was a decrease of $183,000. In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions (“ASU 2022-03”) to clarify the guidance in Topic 820, Fair Value Measurement, when measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of an equity security, and to introduce new disclosure requirements for equity securities subject to contractual sale restrictions that are measured at fair value. The standard became effective for the Company on July 1, 2024. The adoption of the standard did not have a material impact on the Company's Consolidated Financial Statements. In November 2023, the FASB issued Accounting Standards Update No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”), which enhances annual and interim disclosure requirements for reportable segments. The amendments require additional, more detailed disclosures about significant segment expenses and other segment items. The Company adopted ASU 2023-07 retrospectively for its fiscal year 2025 annual Consolidated Financial Statements and will apply it to interim periods beginning in fiscal year 2026. While the adoption of ASU 2023-07 did not have a material impact on the Company’s Consolidated Financial Statements, it resulted in enhanced segment disclosures. Recent Accounting Pronouncements In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), which enhances the transparency and decision usefulness of income tax disclosures. ASU 2023-09 will be effective for fiscal years beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The Company is currently evaluating the impact of ASU 2023-09 on its Consolidated Financial Statement disclosures. In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”), which requires public business entities to disclose specified information about certain costs and expenses. ASU 2024-03 will be effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods with annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2024-03 on its Consolidated Financial Statement disclosures.
