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, 2015. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, United Shareholder Services, Inc. (“USSI”) , 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 Advisor Inc. (“Galileo”). The Company’s wholly-owned subsidiary, USSI, which ceased operations in fiscal year 2014, was legally dissolved in December 2015. U.S. Global Brokerage, Inc. is in the process of winding down operations as discussed in Note 12. Galileo is consolidated with the operations of the Company. The non-controlling interest in this subsidiary is included in “non-controlling interest in subsidiaries” in the equity section of the Consolidated Balance Sheets. Frank Holmes, CEO, and Susan McGee, President and General Counsel, serve as directors of Galileo. The Company's evaluation for consolidation includes whether entities in which it has an interest are variable interest entities (“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 power to direct the activities that most significantly impact the VIE’s economic performance and the obligation to absorb losses of or right to receive benefits from the VIE that could potentially be significant to the VIE. If the VIE qualifies for the investment company deferral, 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. The Company holds variable interests in, but is not deemed to be the primary beneficiary of, the funds it advises. The Company has determined that these entities qualify for the investment company deferral in Accounting Standards Codification (“ASC”) 810-10-65-2 (aa) and thus determines whether it is the primary beneficiary of these entities by virtue of its exposure to the expected losses and expected residual returns of the entity. The Company’s interests in these entities consist of the Company’s direct ownership therein, which in each case is insignificant to the total ownership of the fund, 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 managed entities 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 of these VIEs. 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 six months ended December 31, 2015, 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. Recent Accounting Pronouncements In April 2014, the FASB issued ASU 2014-08, Presentation of Financial Statements and Property, Plant, and Equipment - Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (“ASU 2014-08”). ASU 2014-08 became effective for the Company on July 1, 2015. The adoption of ASU 2014-08 was not material to the consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five-step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP. The standard is effective for annual periods beginning after December 15, 2017, and interim periods therein, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). We are currently evaluating the impact of our pending adoption of ASU 2014-09 on our consolidated financial statements and have not yet determined the method by which we will adopt the standard in 2018. In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern (“ASU 2014-15”). This update requires an entity's management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the date that the financial statements are available to be issued when applicable). When conditions or events raise substantial doubts about an entity’s ability to continue as a going concern, management shall disclose: i) the principal conditions or events that raise substantial doubt about the entity's ability to continue as a going concern; ii) management's evaluation of the significance of those conditions or events in relation to the entity's ability to meet its obligations; and iii) management's plans that are intended to mitigate the conditions or events - and whether or not those plans alleviate the substantial doubt about the entity's ability to continue as a going concern. ASU 2014-15 is effective for the annual period ending after December 15, 2016, and early application is permitted. Management does not currently anticipate that this update will have any impact on the Company’s financial statement disclosures. In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis (“ASU 2015-02”), which amends the consolidation requirements in ASC 810, Consolidation. This standard modifies existing consolidation guidance for reporting organizations that are required to evaluate whether they should consolidate certain legal entities. ASU 2015-02 is effective for fiscal years and interim periods within those years beginning after December 15, 2015, and requires either a retrospective or a modified retrospective approach to adoption. Early adoption is permitted. The Company is currently evaluating the potential impact of this standard on its consolidated financial statements, as well as the available transition methods. In May 2015, the FASB issued ASU 2015-07, Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent) (“ASU 2015-07”). ASU 2015-07 removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the NAV per share practical expedient. The update is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2015, and early adoption is permitted. The update requires the retrospective adoption approach. The Company is currently evaluating the potential impact of this standard on its consolidated financial statements. In November 2015, the FASB issued ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes (“ASU 2015-17”). ASU 2015-17 requires entities to present deferred tax assets and deferred tax liabilities as noncurrent in a classified balance sheet. It simplifies the current guidance, which requires entities to separately present deferred tax assets and liabilities as current or noncurrent in a classified balance sheet. Netting by tax jurisdiction is still required under the new guidance. The update is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods, and early adoption is permitted. Entities are permitted to apply the amendments either prospectively or retrospectively. The Company is currently evaluating the potential impact of this standard on its consolidated financial statements.
