BASIS OF PRESENTATION

BASIS OF PRESENTATION	3 Months Ended

Disclosure Text Block [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	NOTE 1. BASIS OF PRESENTATION U.S. Global Investors, Inc. (the “Company” or “U.S. Global”) has prepared the consolidated financial statements pursuant to accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the rules and regulations of the United States Securities and Exchange Commission (“SEC”) that permit reduced disclosure for interim periods. The financial information included herein reflects all adjustments (consisting solely of normal recurring adjustments), which are, in management’s opinion, necessary for a fair presentation of results for the interim periods presented. The Company has consistently followed the accounting policies set forth in the notes to the consolidated financial statements in the Company’s Form 10-K for the fiscal year ended June 30, 2018, except for the adoption of new accounting pronouncements discussed below. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, U.S. Global Brokerage, Inc., U.S. Global Investors (Bermuda) Limited, U.S. Global Investors (Canada) Limited (“USCAN”), and U.S. Global Indices, LLC, and its 65 percent interest in Galileo Global Equity Advisors Inc. (“Galileo”). U.S. Global Brokerage, Inc. ceased operations in December 2015 and was dissolved on July 27, 2018. Galileo is consolidated with the operations of the Company. The non-controlling interest in this subsidiary is included in “Non-Controlling Interest in Subsidiary” in the equity section of the Consolidated Balance Sheets. Frank Holmes, CEO, and Lisa Callicotte, CFO, serve as directors of Galileo. 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 lack 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, but is not deemed to be the primary beneficiary of, certain funds it advises, specifically, certain funds in U.S. Global Investors Funds (“USGIF” or the “Funds”) and, until November 2017, one of the offshore funds. The Company’s interests in these VIEs consist of the Company’s direct ownership therein and any fees earned but uncollected. See further information about these funds in Notes 2 and 3. 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 3 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 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 $9.7 million at September 30, 2018, and $9.6 million at June 30, 2018. Since the Company is not the primary beneficiary of the above 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 above funds it advises; therefore, the Company does not consolidate any of these funds. The Company holds a variable interest in a fund advised by Galileo, and during fiscal year 2018 held a variable interest in another fund advised by Galileo, but these funds do not qualify as VIEs. Since the funds are not VIEs, the Company evaluated if it should consolidate the funds 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 the funds and, therefore, does not consolidate the funds. However, for one of the funds, the Company’s ownership ranged between approximately 23 and 30 percent during fiscal year 2018 until the investment was redeemed in full, and the Company was considered to have the ability to exercise significant influence. Thus, the investment was accounted for under the equity method of accounting. The Company’s ownership of the other fund has ranged between approximately 20 and 25 percent since original purchase in the third quarter of fiscal year 2018, and was approximately 25 percent at September 30, 2018. The Company is considered to have the ability to exercise significant influence, and thus, that investment has been also accounted for the investment under the equity method of accounting. See further information about these investments in Note 2. All significant intercompany balances and transactions have been eliminated in consolidation. Certain amounts have been reclassified for comparative purposes. The results of operations for the three months ended September 30, 2018, are not necessarily indicative of the results to be expected for the entire year. The unaudited interim financial information in these condensed financial statements should be read in conjunction with the consolidated financial statements contained in the Company’s annual report.

Disclosure Text Block Supplement [Abstract]
Investments and Other Noncurrent Assets [Text Block]	NOTE 2. INVESTMENTS As of September 30, 2018, the Company held investments in securities at fair value totaling approximately $14.3 million with a cost basis of approximately $12.3 million. The fair value of these investments is 53.3 percent of the Company’s total assets at September 30, 2018. In addition, the Company held other investments of $2.2 million and investments of approximately $281,000 accounted for under the equity method of accounting. As discussed in Note 1, the Company adopted ASU 2016-01, which amended the guidance on the classification and measurement of investments in equity securities, effective July 1, 2018. There is no longer an available-for-sale classification (with changes in fair value reported in other comprehensive income) for equity securities with readily determinable fair values. Under the amended guidance, all of the Company’s equity investments with readily determinable fair values are classified as securities at fair value, and changes in unrealized gains or losses are reported in current period earnings. 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. For these securities, the Company generally elects to value using the measurement alternative, under which such securities are measured at cost, less impairment, plus or minus observable price changes for identical or similar securities of the same issuer with such changes recorded in investment income (loss). Prior to fiscal year 2019 and the adoption of ASU 2106-01, these investments were accounted for under the cost method of accounting and evaluated periodically for impairment. See further information about these investments in a separate section of this note. The cost basis of investments may also be adjusted for amortization of premium or accretion of discount on debt securities held or the recharacterization of distributions from investments in partnerships. The following details the components of the Company’s investments recorded at fair value as of September 30, 2018, and June 30, 2018. Note that the change in presentation is the result of the adoption of ASU 2016-01.

Included in the above table as of September 30, 2018, was $9.6 million at fair value invested in USGIF. The following table shows the gross unrealized losses and fair values of available-for-sale investment securities with unrealized losses aggregated by investment category and length of time that individual securities were in a continuous unrealized loss position as of June 30, 2018. No disclosures are required as of September 30, 2018, due the adoption of ASU 2016-01.

Prior to the adoption of ASU 2016-01, investment income (loss) from the Company’s investments included: • realized gains and losses on sales of securities; • unrealized gains and losses on trading securities; • realized foreign currency gains and losses; • other-than-temporary impairments on available-for-sale securities; • other-than-temporary impairments on held-at-cost securities; and • dividend and interest income.

These classifications were used prior to the adoption of ASU 2016-01 effective July 1, 2018 . 2 The prior year amount shown includes $686 in unrealized gains on trading securities for the three months ended September 30, 2017 (classification used prior to the adoption of ASU 2016-01 effective July 1, 2018). The three months ended September 30, 2018, includes $951,000 of net unrealized losses recognized on securities at fair value; all of these investments were still held at September 30, 2018. The majority of this amount is related to declines in unrealized gains on securities formerly classified as available-for-sale, which previously would have been reported through other comprehensive income rather than in investment income. Proceeds from sales of available-for-sale investments were approximately $32,000 for the three months ended September 30, 2017. Gross gains on sales of available-for-sale investments were approximately $7,000 and there were no gross losses on sales of available-for-sale investments for the three months ended September 30, 2017. No disclosures are required for fiscal year 2019 due to the adoption of ASU 2016-01. Prior to fiscal year 2019, gains and losses realized upon sales of available-for-sale investments were reclassified from other comprehensive income into investment income. Investment income can be volatile and varies depending on market fluctuations, the Company’s ability to participate in investment opportunities, and timing of transactions. The Company expects that gains and losses will continue to fluctuate in the future. Fair Value Hierarchy ASC 820, Fair Value Measurement and Disclosures Financial instruments measured and reported at fair value are classified and disclosed in one of the following categories: Level 1 – Valuations based on quoted prices in active markets for identical assets or liabilities at the reporting date. Since valuations are based on quoted prices that are readily and regularly available in an active market, value of these products does not entail a significant degree of judgment. Level 2 – Valuations based on quoted prices in markets for which not all significant inputs are observable, directly or indirectly. Corporate debt securities valued in accordance with the evaluated price supplied by an independent service are categorized as Level 2 in the hierarchy. Other securities categorized as Level 2 include securities valued at the mean between the last reported bid and ask quotation and securities valued with an adjustment to the quoted price due to restrictions. Level 3 – Valuations based on inputs that are unobservable and significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the financial instrument. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with the investing in those securities. Because of the inherent uncertainties of valuation, the values reflected may materially differ from the values received upon actual sale of those investments. For actively traded securities, the Company values investments using the closing price of the securities on the exchange or market on which the securities principally trade. If the security is not traded on the last business day of the quarter, it is generally valued at the mean between the last bid and ask quotation. The fair value of a security that has a restriction is based on the quoted price for an otherwise identical unrestricted instrument that trades in a public market, adjusted for the estimated effect of the restriction. Mutual funds, which include open- and closed-end funds, exchange-traded funds, and offshore funds, are valued at net asset value or closing price, as applicable. Certain corporate debt securities not traded on an exchange may be valued by an independent pricing service using an evaluated quote based on such factors as institutional-size trading in similar groups of securities, yield, quality maturity, coupon rate, type of issuance and individual trading characteristics and other market data. As part of its independent price verification process, a portfolio management team, which includes representatives from the investment and accounting departments, periodically reviews the fair value provided by the pricing service using information such as transactions in these investments, broker quotes, market transactions in comparable investments, general market conditions and the issuer’s financial condition. Certain debt securities may be valued based on review of similarly structured issuances in similar jurisdictions, when possible, or based on other traded debt securities issued by the issuer. The portfolio management team also takes into consideration numerous other factors that could affect valuation such as overall market conditions, liquidity of the security and bond structure. For other securities included in the fair value hierarchy with unobservable inputs, the portfolio management team considers a number of factors in determining a security’s fair value, including the security’s trading volume, market values of similar class issuances, investment personnel’s judgment regarding the market experience of the issuer, financial status of the issuer, the issuer’s management, and back testing, as appropriate. The fair values may differ from what may have been used had a broader market for these securities existed. The portfolio management team reviews inputs and assumptions and reports material items to the board of directors. Securities which do not have readily determinable fair values are also periodically reviewed by the portfolio management team. The following presents fair value measurements, as of September 30, 2018, and June 30, 2018, for the major categories of U.S. Global’s investments measured at fair value on a recurring basis: September 30, 2018 Quoted Prices Significant Other Inputs Significant Unobservable Inputs (dollars in thousands) (Level 1) (Level 2) (Level 3) Total Securities at fair value Common stock - International $ 4,705 $ - $ - $ 4,705 Common stock - Domestic - - - - Mutual funds - Fixed income 8,790 - - 8,790 Mutual funds - Domestic equity 820 - - 820 Total securities at fair value $ 14,315 $ - $ - $ 14,315 June 30, 2018 Quoted Prices Significant Other Inputs Significant Unobservable Inputs (dollars in thousands) (Level 1) (Level 2) (Level 3) Total Trading securities Mutual funds - Fixed income $ 7,807 $ - $ - $ 7,807 Mutual funds - Domestic equity 372 - - 372 Other - - - - Total trading securities 8,179 - - 8,179 Available-for-sale securities Common stock - International 5,673 - - 5,673 Mutual funds - Fixed income 991 - - 991 Mutual funds - Domestic equity 422 - - 422 Total available-for-sale securities 7,086 - - 7,086 Total securities at fair value $ 15,265 $ - $ - $ 15,265 As of September 30, 2018, and June 30, 2018, 100 percent of the Company’s financial assets were classified in the fair value hierarchy as Level 1. The Company has an investment in 10 million common shares of HIVE Blockchain Technologies Ltd. (“HIVE”), a company that is headquartered and traded in Canada with cryptocurrency mining facilities in Iceland and Sweden, at a cost of $2.4 million. The shares are subject to Canadian securities regulations. The investment, classified as available-for-sale prior to the adoption of ASU 2016-01, was valued at approximately $4.6 million at September 30, 2018, and $5.6 million at June 30, 2018. Cryptocurrency markets and related stocks have been, and are expected to continue to be, volatile. Cryptocurrency mining is considered an early stage high-risk industry, and the nature of mining is expected to evolve. There has been significant volatility in the market price of HIVE, which has materially impacted the investment’s value included on the balance sheet and unrealized gain (loss) recognized in investment income. The unit trust investment fund managed by Galileo described below that was held as of September 30, 2018, also holds common shares of HIVE. The Company had both a direct ownership of HIVE and a combined direct and indirect ownership of HIVE of approximately 3.0 percent as of September 30, 2018. Frank Holmes is the non-executive chairman of HIVE and held shares and options at September 30, 2018. Effective August 31, 2018, Mr. Holmes was named Interim Executive Chairman of HIVE while a search for a new CEO is undertaken. Other Investment s The carrying value of equity securities without readily determinable fair values as of September 30, 2018, is approximately $2.2 million. There was an impairment adjustment to one security of $29,000 during the three months ended September 30, 2018. Cumulative impairment adjustments to all equity securities without readily determinable fair values are $378,000 since their acquisitions through September 30, 2018. Impairments are recognized as a loss in the Company’s earnings. The cumulative amount of other downward adjustments, which primarily consist of return of capital distributions, is $605,000. There have been no upward adjustments to these investments. Investment s Classified as Equity Method Investments classified as equity method consist of investments in companies in which the Company is able to exercise significant influence but not control. Under the equity method of accounting, the investment is initially recorded at cost, then the Company’s proportional share of investee’s underlying net income or loss is recorded as a component of “other income (loss)” with a corresponding increase or decrease to the carrying value of the investment. Distributions received from the investee reduce the Company’s carrying value of the investment. These investments are evaluated for impairment if events or circumstances arise that indicate that the carrying amount of such assets may not be recoverable. During fiscal year 2018, the Company, through USCAN, invested approximately $401,000 in the Galileo Technology and Blockchain Fund, a Canadian unit trust investment fund managed by Galileo. The Company owns approximately 25 percent of the fund as of September 30, 2018, and the Company is considered to have the ability to exercise significant influence. Thus, the investment is accounted for under the equity method of accounting. Under the equity method, the Company’s proportional share of the fund’s net income or loss, which primarily consists of realized and unrealized gains and losses on investments offset by fund expenses, is recognized in the Company’s earnings. Included in other income for the three months ended September 30, 2018, is $7,000 of equity method loss for this investment. The Company’s investment in the fund was valued at approximately $281,000 at September 30, 2018. This investment was not held at September 30, 2017. Frank Holmes also directly held an investment in the fund as of September 30, 2018. This fund has a concentration in technology and blockchain companies, which may result in volatility in the fund’s valuation. During fiscal year 2018, the Company, through USCAN, invested approximately $500,000 in the Galileo Partners Fund, a Canadian unit trust investment fund managed by Galileo. The investment was subsequently redeemed in full during fiscal year 2018, and the Company no longer had an investment in the Galileo Partners Fund as of June 30, 2018, or September 30, 2018. During the period of ownership, the investment was accounted for under the equity method of accounting. Included in other income for the three months ended September 30, 2017, is $1.5 million of equity method income of Galileo Partners Fund. Summarized income statement information on the Galileo Partners Fund for the period of the Company’s investment through September 30, 2017, is as follows: Galileo Partners Fund Summary Financial Information For the Period from August 31, 2017 (investment) to September 30, 2017 (dollars in thousands) Realized gains on sales of investments $ 154 Unrealized gains on investments 6,102 Fund fees and expenses, including performance fees (1,432 ) Net income of fund $ 4,824 Company's share of income from equity method investment $ 1,513

STOCKHOLDERS’ EQUITY Payment of cash dividends is within the discretion of the Company’s board of directors and is dependent on earnings, operations, capital requirements, general financial condition of the Company, and general business conditions. A monthly dividend of $0.0025 per share was paid during fiscal year 2018 and for July 2018 through September 2018. Subsequent to September 30, 2018, the Board authorized a monthly dividend of $0.0025 per share for October 2018 through December 2018, at which time it will be considered for continuation. The Company has a share repurchase program, approved by the Board of Directors, authorizing the Company to annually purchase up to $2.75 million of its outstanding common shares, as market and business conditions warrant, on the open market in compliance with Rule 10b-18 of the Securities Exchange Act of 1934 through December 31, 2018. The repurchase program has been in place since December 2012, and the Board of Directors has annually renewed the repurchase program each calendar year. The acquired shares may be used for corporate purposes, including shares issued to employees in the Company’s stock-based compensation programs. For the three months ended September 30, 2018, and 2017, the Company repurchased 1,000 and 9,199 class A shares using cash of $2,000 and $14,000, respectively.

Earnings Per Share [Abstract]
Earnings Per Share [Text Block]	NOTE 8 . EARNINGS PER SHARE The basic earnings per share (“EPS”) calculation excludes dilution and is computed by dividing net income 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 following table sets forth the computation for basic and diluted EPS: Three Months Ended September 30, (dollars in thousands, except per share data) 2018 2017 Net Income (Loss) $ (1,232 ) $ 1,236 Less: Net Loss Attributable to Non-Controlling Interest (83 ) (34 ) Net Income (Loss) Attributable to U.S. Global Investors, Inc. $ (1,149 ) $ 1,270 Weighted average number of outstanding shares Basic 15,144,884 15,182,651 Effect of dilutive securities Employee stock options - - Diluted 15,144,884 15,182,651 Earnings Per Share Attributable to U.S. Global Investors, Inc. Basic $ (0.08 ) $ 0.08 Diluted $ (0.08 ) $ 0.08 The diluted EPS calculation excludes the effect of stock options when their exercise prices exceed the average market price for the period. For the three months ended September 30, 2018, and 2017, 4,000 and 2,000 options were excluded from diluted EPS, respectively. During the three months ended September 30, 2018, and 2017, the Company repurchased class A shares on the open market. Upon repurchase, these shares are classified as treasury shares and are deducted from outstanding shares in the earnings per share calculation.

INCOME TAXES

INCOME TAXES	3 Months Ended
	Sep. 30, 2018
Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	NOTE 9 . INCOME TAXES The Company and its non-Canadian subsidiaries file a consolidated U.S. federal income tax return. USCAN and Galileo file separate tax returns in Canada. 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 Tax Cuts and Jobs Act (“the Act”) was enacted on December 22, 2017. The Act reduced the U.S. federal corporate tax rate from 35 percent to 21 percent. The rate change was effective on January 1, 2018; therefore, the Company’s U.S. statutory tax rate for the fiscal year ended June 30, 2019, is 21 percent, while the rate for fiscal year 2018 was a bended rate of approximately 28 percent. The current applicable Canadian statutory rate for the Canadian subsidiaries is approximately 26.5 percent. At September 30, 2018, the Company has not completed its accounting for the tax effects of enactment of the Act; however, in certain cases, as described below, the Company has made a reasonable estimate of the effects on existing deferred tax balances and the one-time transition tax. The Securities and Exchange Commission has issued guidance that allows for a measurement period of up to one year after the enactment date of the Act to finalize the recording of the related tax impacts. The final transitional impacts of the Act may differ from the initial estimates. The Act also established new tax provisions that become effective in future periods, including but not limited to eliminating the corporate alternative minimum tax, creating the base erosion anti-abuse tax (“BEAT”), establishing new limitations on deductible interest expense and certain executive compensation, creating a new provision designed to tax global intangible low-tax income (“GILTI”) and generally eliminating U.S. Federal income taxes on dividends from foreign subsidiaries. The Company has included these provisions in its U.S. Federal income tax estimates. Under the new GILTI tax rules, an accounting policy election must be made to either treat taxes due on future GILTI inclusions in U.S. taxable income as a current period expense when incurred or reflect as a component of deferred taxes. This provision became effective for the Company on July 1, 2018. Given the complexity of the GILTI provisions, the Company is still evaluating the tax impact and has not yet made the accounting policy election. The Company has, however, included an estimate of the current GILTI impact in the tax provision for fiscal 2019. Provisional amounts Deferred tax assets and liabilities: Certain domestic-related deferred tax assets and liabilities were remeasured in the second quarter of fiscal year 2018 based on the rates at which they are expected to reverse in the future, which is generally 21 percent The Company is still analyzing certain aspects of the Act and refining the calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. As a valuation allowance is recorded for the full amount of these net deferred tax assets, the remeasurement of the net deferred tax assets was offset by a corresponding remeasurement of the valuation allowance. Foreign tax effects: The one-time transition tax is based on total post-1986 earnings and profits (“E&P”) that were previously deferred from U.S. income taxes. The Company has not yet completed its calculation of the total post-1986 E&P for these foreign subsidiaries. Carryovers For U.S. federal income tax purposes at September 30, 2018, the Company has U.S. federal net operating loss carryovers of $5.3 million with $1.9 million and $2.7 million expiring in fiscal years 2035 and 2036, respectively, and $660,000 with no expiration. Certain limitations apply to the utilization of net operating losses generated after fiscal year 2018. The Company has capital loss carryovers of $1.1 million with $750,000 and $348,000 expiring in fiscal years 2022 and 2023, respectively. The Company has charitable contribution carryovers totaling approximately $69,000 with $34,000; $19,000; $5,000; and $11,000 expiring in fiscal years 2019, 2020, 2021, and 2023, respectively. For Canadian income tax purposes, Galileo has net operating loss carryovers of $568,000 with $103,000; $45,000; $124,000; $73,000; and $223,000 expiring in fiscal years 2027, 2030, 2036, 2037 and 2038, respectively. If certain changes in the Company's ownership should occur, there could be an annual limitation on the amount of net operating loss carryovers that could be utilized. A valuation allowance is provided when it is more likely than not that some portion of the deferred tax amount will not be realized. At September 30, 2018, and June 30, 2018, a valuation allowance of $1.9 million and $1.7 million, respectively, was included to fully reserve for net operating loss carryovers, other carryovers and certain book/tax differences in the balance sheet.

Commitments and Contingencies Disclosure [Text Block]	NOTE 1 2 . CONTINGENCIES AND COMMITMENTS The Company continuously reviews all investor, employee and vendor complaints, and pending or threatened litigation. The likelihood that a loss contingency exists is evaluated through consultation with legal counsel, and a loss contingency is recorded if probable and reasonably estimable.

These matters are subject to various uncertainties, and it is possible that some of these matters may be resolved unfavorably. The Company establishes accruals for matters for which the outcome is probable and can be reasonably estimated.

The Company has consistently followed the accounting policies set forth in the notes to the consolidated financial statements in the Company’s Form 10-K for the fiscal year ended June 30, 2018, except for the adoption of new accounting pronouncements discussed below. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, U.S. Global Brokerage, Inc., U.S. Global Investors (Bermuda) Limited, U.S. Global Investors (Canada) Limited (“USCAN”), and U.S. Global Indices, LLC, and its 65 percent interest in Galileo Global Equity Advisors Inc. (“Galileo”). U.S. Global Brokerage, Inc. ceased operations in December 2015 and was dissolved on July 27, 2018. Galileo is consolidated with the operations of the Company. The non-controlling interest in this subsidiary is included in “Non-Controlling Interest in Subsidiary” in the equity section of the Consolidated Balance Sheets. Frank Holmes, CEO, and Lisa Callicotte, CFO, serve as directors of Galileo. 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 lack 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, but is not deemed to be the primary beneficiary of, certain funds it advises, specifically, certain funds in U.S. Global Investors Funds (“USGIF” or the “Funds”) and, until November 2017, one of the offshore funds. The Company’s interests in these VIEs consist of the Company’s direct ownership therein and any fees earned but uncollected. See further information about these funds in Notes 2 and 3. 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 3 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 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 $9.7 million at September 30, 2018, and $9.6 million at June 30, 2018. Since the Company is not the primary beneficiary of the above 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 above funds it advises; therefore, the Company does not consolidate any of these funds. The Company holds a variable interest in a fund advised by Galileo, and during fiscal year 2018 held a variable interest in another fund advised by Galileo, but these funds do not qualify as VIEs. Since the funds are not VIEs, the Company evaluated if it should consolidate the funds 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 the funds and, therefore, does not consolidate the funds. However, for one of the funds, the Company’s ownership ranged between approximately 23 and 30 percent during fiscal year 2018 until the investment was redeemed in full, and the Company was considered to have the ability to exercise significant influence. Thus, the investment was accounted for under the equity method of accounting. The Company’s ownership of the other fund has ranged between approximately 20 and 25 percent since original purchase in the third quarter of fiscal year 2018, and was approximately 25 percent at September 30, 2018. The Company is considered to have the ability to exercise significant influence, and thus, that investment has been also accounted for the investment under the equity method of accounting. See further information about these investments in Note 2. All significant intercompany balances and transactions have been eliminated in consolidation. Certain amounts have been reclassified for comparative purposes. The results of operations for the three months ended September 30, 2018, are not necessarily indicative of the results to be expected for the entire year. The unaudited interim financial information in these condensed financial statements should be read in conjunction with the consolidated financial statements contained in the Company’s annual report.
