	ORGANIZATION
	U.S. Global Investors, Inc. (the “Company” or “U.S. Global”) serves as investment adviser to U.S. Global Investors funds (“USGIF” or the “Fund(s)”), a Delaware statutory trust that is a no-load, open-end investment company offering shares in numerous mutual funds to the investing public. The Company also provides administrative services and distribution to USGIF and through December 6, 2013, provided transfer agency functions. For these services, the Company receives fees from USGIF. The Company also provides advisory services to offshore clients and, effective June 1, 2014, holds a controlling interest in Galileo Global Equity Advisors Inc. (“Galileo”), a privately held Toronto-based asset management firm. See Note 2 Significant Accounting Policies and Note 3 Business Combination for additional information on the acquisition of controlling interest of Galileo.
	U.S. Global formed the following companies to provide transfer agent and distribution services to USGIF: United Shareholder Services, Inc. (“USSI”) and U.S. Global Brokerage, Inc. (“USGB”).
	The Company formed three subsidiaries utilized primarily for corporate investment purposes: U.S. Global Investors (Guernsey) Limited (“USGG”), incorporated in Guernsey (on August 3, 2013, USGG was dissolved), U.S. Global Investors (Bermuda) Limited (“USBERM”), incorporated in Bermuda, and U.S. Global Investors (Canada) Limited (“USCAN”), formed in March 2013. In addition, in July 2013, the Company created U.S. Global Indices, LLC, a Texas limited liability company, of which the Company is the sole member. U.S. Global Indices, LLC did not have operations during fiscal year 2014.

	SIGNIFICANT ACCOUNTING POLICIES
	Principles of Consolidation. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries: USSI, USGB, USGG, USBERM and USCAN.
	In addition, effective June 1, 2014, the Company, through USCAN, completed its purchase of an additional 15 percent interest in Galileo from the company’s founder, Michael Waring. This additional investment brings USCAN’s ownership to 65 percent of the issued and outstanding shares of Galileo and represents a controlling interest of Galileo. With the additional investment, the Company expects to increase its presence in Canada. The non-controlling interest in this subsidiary is included in “non-controlling interest in subsidiary” in the equity section of the Consolidated Balance Sheets. See Note 3 Business Combination for additional information. After the purchase of the additional interest, Galileo changed its fiscal year end from December 31 to June 30, effective June 30, 2014, to correspond to the Company’s year end. This change was treated as a change in accounting principle.
	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 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 6 Investment Management and Other Fees 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.
	Prior to March 31, 2014, the Company classified investments in private and venture capital companies as available-for-sale Level 3 securities. Since these equity investments do not have readily determinable fair values, these investments should have been classified as “other investments” on the Consolidated Balance Sheets and accounted for under the cost method of accounting rather than at fair value. The Company determined that the difference between the fair value and the value using the cost method of accounting for these securities is not material to “accumulated other comprehensive income (loss)” or “other comprehensive income (loss)” and did not affect net income or earnings per share. To correct this balance sheet misclassification, the Company has reclassified $385,000 of investments as “other investments” on the face of the Consolidated Balance Sheets at cost adjusted for impairments. This reclassification was not material to “accumulated other comprehensive income (loss)” or “other comprehensive income (loss)” and did not affect net income or earnings per share.
	All significant intercompany balances and transactions have been eliminated in consolidation. Certain amounts have been reclassified for comparative purposes.
	Business Combinations. Business combinations are accounted for under the acquisition method of accounting. Results of operations of an acquired business are included from the date of acquisition. Management estimates the fair value of the acquired assets, including identifiable intangible assets, assumed liabilities, and non-controlling interest in the acquiree based on their estimated fair values as of the date of acquisition. Any excess acquisition date fair value of the consideration transferred over fair value of the acquired net assets, if any, is recorded as “goodwill” on the Consolidated Balance Sheets. Any excess fair value of the acquired net assets over the acquisition date fair value of the consideration transferred is recorded as a gain on the Consolidated Statements of Operations.
	Cash and Cash Equivalents. Cash and cash equivalents include highly liquid investments with original maturities of three months or less.
	Investments. The Company classifies its investments based on intent at the time of purchase and reevaluates such designation as of each reporting period date. The Company records security transactions on trade date. Realized gains (losses) from security transactions are calculated on the first-in/first-out cost basis, unless otherwise identifiable, and are recorded in earnings on the date of sale.
	Trading Securities. Securities that are purchased and held principally for the purpose of selling in the near term are classified as trading securities and reported at fair value. Unrealized gains and losses on these securities are included in Investment income (loss).
	Held-to-Maturity Securities. Investments in debt securities that are purchased with the intent and ability to hold until maturity are classified as held-to-maturity and measured at amortized cost. The Company currently has no investments in held-to-maturity securities.
	Available-for-sale Securities. Investments that are neither trading securities nor held-to-maturity securities and for which the Company does not have significant influence are classified as available-for-sale securities and reported at fair value. Unrealized gains and losses on these available-for-sale securities are excluded from earnings, reported net of tax as a separate component of shareholders’ equity, and recorded in earnings on the date of sale.
	The Company evaluates its available-for-sale investments for other-than-temporary decline in value on a periodic basis. This may exist when the fair value of an investment security has been below the current value for an extended period of time. When a security in the Company’s investment portfolio has an unrealized loss in fair value that is deemed to be other than temporary, the Company reduces the book value of such security to its current fair value, recognizing the credit related decline as a realized loss in the Consolidated Statements of Operations and a revised GAAP cost basis for the security is established. For available-for-sale securities with declines in value deemed other than temporary, the unrealized loss recorded net of tax in accumulated other comprehensive income (loss) is realized as a charge to net income.
	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. These equity investments are accounted for under the cost method of accounting and evaluated for impairment. The Company considers many factors in determining impairment, including the severity and duration of the decline in value below cost, the Company’s interest and ability to hold the security for a period of time sufficient for an anticipated recovery in value, and the financial condition and specific events related to the issuer.
	Equity Method Investments (Investment in Galileo). 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 Company’s proportional share of investee’s underlying net income or loss is recorded as a component of “other income” 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. No impairment was recognized for the Company’s equity method investment during the years presented. No investments were held at June 30, 2014, that are accounted for using the equity method. See Note 3 Business Combination for further information.
	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 because of the short maturity of the instruments.
	Receivables. Receivables consist primarily of monthly advisory and other fees owed to the Company by USGIF as well as receivables related to offshore investment advisory fees. Receivables also include advisory fees owed to Galileo by the funds and clients it manages. Management considers various factors including current sales amounts, historical charge-offs and specific accounts identified as high risk. Uncollectible accounts receivable, if any, are charged against the allowance for doubtful accounts when all reasonable efforts to collect the amounts due have been exhausted. The Company had no allowance for doubtful accounts as of June 30, 2014, and 2013.
	Property and Equipment. Fixed assets are recorded at cost. Other than as noted below, 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. Galileo fixed assets, consisting of furniture, equipment and leasehold improvements, are depreciated over 2 to 5 years.
	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 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.
	Intangible Asset. An intangible asset, consisting of a non-compete agreement, acquired in connection with the acquisition of Galileo shares effective June 1, 2014, is recorded at fair value determined using a discounted cash flow model as of the date of acquisition. The discounted cash flow model included various factors to project future cash flows expected to be generated from the asset, including: (1) an estimated rate of change for underlying managed assets; (2) expected revenue per managed assets; (3) incremental operating expenses; and (4) a discount rate. Management estimates a rate of change for underlying managed assets based on an estimated net redemption or sales rate. Expected revenue per managed assets and incremental operating expenses of the acquired assets are generally based on contract terms.
	The Company has determined that the non-compete agreement has a finite useful life. The Company will amortize this finite-lived identifiable intangible asset on a straight-line basis over its estimated useful life, currently expected to be approximately 2 years. Management periodically evaluates the remaining useful lives and carrying values of intangible assets to determine whether events and circumstances indicate that a change in the useful life or impairment in value may have occurred. Indicators of impairment monitored by management include a decline in the level of managed assets, changes to contractual provisions underlying the intangible assets and reductions in underlying operating cash flows. Should there be an indication of a change in the useful life or impairment in value of the finite-lived intangible asset, the Company compares the carrying value of the asset and its related useful life to the projected discounted cash flows expected to be generated from the underlying managed assets over its remaining useful life to determine whether impairment has occurred. If the carrying value of the asset exceeds the discounted cash flows, the asset is written down to its fair value determined using discounted cash flows.
	Non-Controlling Interests. The Company reports “non-controlling interest in subsidiary” as equity, separate from parent’s equity, on the Consolidated Balance Sheets. In addition, the Company’s Consolidated Statements of Operations includes “net income (loss) attributable to non-controlling interest.”
	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.
	Stock-Based Compensation. Stock-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.
	Income Taxes. The Company and its subsidiaries file a consolidated federal income tax return. 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. As of June 30, 2014, the Company did not have any accrued interest or penalties related to uncertain tax positions. The tax years from 2010 through 2013 remain open to examination by the tax jurisdictions to which the Company is subject.
	Revenue Recognition. The Company earns substantially all of its revenues from advisory, distribution services, and administrative fees that are calculated as a percentage of assets under management and are recorded as revenue as services are performed. Offshore advisory client contracts provide for monthly management fees, in addition to performance fees. The advisory contract for the equity funds within USGIF provides for a performance fee on the base advisory fee that are calculated and recorded monthly. Shareholder services fees are based on the assets of the funds held through institutions. Revenue shown on the Consolidated Statements of Operations is net of fee waivers.
	Dividends and Interest. Dividends are recorded on the ex-dividend date, and interest income is recorded on an accrual basis. Both dividends and interest income are included in investment income.
	Advertising Costs. The Company expenses advertising costs as they are incurred. Certain sales materials, which are considered tangible assets, are capitalized and then expensed during the period in which they are distributed. Net advertising expenditures were $615,000; $862,000; and $1.2 million during fiscal years 2014, 2013, and 2012, respectively.
	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 these translations are excluded from income and are recorded in “accumulated other comprehensive income (loss)” on the Consolidated Balance Sheets. 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 “investment income (loss)” on the Consolidated Statements of Operations.
	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. The Company computes and presents earnings per share attributable to U.S. Global Investors, Inc. in accordance with ASC 260, Earnings Per Share. Basic earnings per share (“EPS”) excludes dilution and is computed by dividing net income (loss) attributable to U.S. Global Investors, Inc. 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.
	Accumulated Other Comprehensive Income (Loss). Accumulated other comprehensive income (loss) (“AOCI”), net of tax is reported in the Consolidated Balance Sheets and the Consolidated Statements of Shareholders’ Equity and includes the unrealized gains and losses on securities classified as available-for-sale and foreign currency translation adjustments.
	Recent Accounting Pronouncements
	In July 2013, the FASB issued Accounting Standard Update (“ASU”) No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11”). ASU 2013-11 became effective for the Company on July 1, 2014. Management is evaluating the ASU and its potential impact on the financial statements.
	In April 2014, the FASB issued ASU No. 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 will become effective for the Company on July 1, 2015. Management is evaluating the ASU and its potential impact on the financial statements.
	In May 2014, the FASB issued ASU No. 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, 2016, 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 2017.

	BUSINESS COMBINATION
	Effective March 31, 2013, the Company, through USCAN, purchased 50 percent of the issued and outstanding shares of Galileo Global Equity Advisors, Inc., a privately held Toronto-based asset management firm, for $600,000 cash.
	Effective June 1, 2014, the Company, through USCAN, completed its purchase of an additional 15 percent interest in Galileo from the company’s founder, Michael Waring, for $180,000 cash. This strategic investment brings USCAN’s ownership to 65 percent of the issued and outstanding shares of Galileo, which represents a controlling interest of Galileo. Through Galileo, the Company expects to increase its presence in Canada. 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.
	From March 31, 2013, to June 1, 2014, the Company accounted for its interest in Galileo under the equity method with its share of Galileo’s profit or loss recognized in earnings, including $20,000 and $54,000 in other income in fiscal year 2014 and 2013, respectively.
	The Company accounted for the June 1, 2014, Galileo share purchase using the acquisition method of accounting, which requires, among other things, that the fair values of assets acquired, including an intangible asset, and liabilities assumed, along with the fair value of the non-controlling interest in the subsidiary, be recognized on the Consolidated Balance Sheets as of the acquisition date.
	Business combinations achieved in stages also must value prior investments at fair value. A $161,000 increase in fair value of the Company’s initial investment was recognized as a gain and included in investment income.
	The Company recognized a gain of $129,000 on the June 1, 2014, purchase since the fair value of the net assets acquired was greater than the fair value of consideration given. This gain is also included within investment income.
	The Consolidated Balance Sheet as of June 30, 2014, reflects the purchase price allocations based on an assessment of the fair value of the assets acquired, liabilities assumed and non-controlling interest in subsidiary. The Company is continuing to evaluate the transaction and future changes to the amounts recorded could occur. The table below presents the preliminary purchase price allocation as of the June 1, 2014, acquisition date:

	DISCONTINUED OPERATIONS
	The Company’s Board of Directors formally agreed on August 23, 2013, to exit the transfer agency business so that the Company could focus more on its core strength of investment management. USSI served as transfer agent until conversion to the new transfer agent on December 9, 2013.
	The transfer agency results, together with expenses associated with discontinuing transfer agency operations, are reflected as “discontinued operations” in the Consolidated Statements of Operations and are therefore, excluded from continuing operations results. These expenses include approximately $65,000 of expenses related to leased equipment that will not be utilized. Comparative periods shown in the Consolidated Financial Statements have been adjusted to conform to this presentation.
	As of June 30, 2014, remaining liabilities related to the transfer agency business totaled approximately $47,000.
	The components of loss from discontinued operations were as follows:

	INVESTMENTS
	As of June 30, 2014, the Company held investments with a fair value of $24.0 million and a cost basis of $22.9 million. The market value of these investments is approximately 63.4 percent of the Company’s total assets. In addition, the Company held other investments of $1.4 million.
	Investments in securities classified as trading are reflected as current assets on the Consolidated Balance Sheets at their fair market value. Unrealized gains and losses on trading securities are included in earnings in the Consolidated Statements of Operations.
	Investments in securities classified as available-for-sale, which may not be readily marketable but have readily determinable fair values, are reflected as non-current assets on the Consolidated Balance Sheets at their fair value. Unrealized gains and losses on available-for-sale securities are excluded from earnings and reported in other comprehensive income (loss) as a separate component of shareholders’ equity until realized.
	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. These equity investments are accounted for under the cost method of accounting and evaluated for impairment. The Company considers many factors in determining impairment, including the severity and duration of the decline in value below cost, the Company’s interest and ability to hold the security for a period of time sufficient for an anticipated recovery in value, and the financial condition and specific events related to the issuer. When an impairment of an equity security is determined to be other-than-temporary, the impairment is recognized in earnings.
	In December 2013, the shareholders of the U.S. Government Securities Savings Fund approved a proposal resulting in the conversion of the fund from a money market fund to a U.S. Government ultra-short bond fund that is not a money market fund. The fund was renamed U.S. Government Securities Ultra-Short Bond Fund (“Government Fund”). Prior to the conversion, while the fund was a money market fund, the amount held in the fund was classified as a cash equivalent. After the conversion, the amount held in the fund is classified as a Level 1 trading mutual fund investment. The amount held in the fund by the Company as of the conversion date was $14.1 million.
	The following details the components of the Company’s investments recorded at fair value as of June 30, 2014, and 2013:

Many of the investments included above are early-stage or start-up businesses whose fair values fluctuate.
Fair Value Hierarchy
ASC 820, Fair Value Measurement and Disclosures, defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 establishes a hierarchy that prioritizes inputs to valuation techniques used to measure fair value and requires companies to disclose the fair value of their financial instruments according to a fair value hierarchy (i.e., Levels 1, 2, and 3 inputs, as defined below). The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. Additionally, companies are required to provide enhanced disclosures regarding instruments in the Level 3 category (which have inputs to the valuation techniques that are unobservable and require significant management judgment), including a reconciliation of the beginning and ending values separately for each major category of assets or liabilities.
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 included securities valued at the mean between the last reported bid and ask quotation.
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. 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 are 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, the Company 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. Debt securities that are not valued by an independent pricing service are valued based on review of similarly structured issuances in similar jurisdictions when possible. The Company also takes into consideration numerous other factors that could affect valuation such as overall market conditions, liquidity of the security and bond structure. Securities for which market quotations are not readily available are valued at their fair value as determined by the portfolio management team. The portfolio management team includes representatives from the investment, accounting and legal/compliance departments. The portfolio management team meets periodically to consider 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.
Prior to March 31, 2014, the Company classified investments that were valued using the mean between the last reported bid ask quotation as Level 1 investments. The Company has determined that it is reasonable to classify these securities as Level 2 investments. This reclassification does not affect balance sheet presentation, net income or earnings per share.

As of June 30, 2014, approximately 90 percent of the Company’s financial assets, measured at fair value, are derived from Level 1 inputs, including SEC-registered mutual funds and equity securities traded on an active market; nine percent are derived from Level 2 inputs, including investments in offshore funds; and the remaining one percent are Level 3 inputs. As of June 30, 2013, approximately 58 percent of the Company’s financial assets measured at fair value are derived from Level 1 inputs including SEC-registered mutual funds and equity securities traded on an active market, 40 percent are derived from Level 2 inputs, including investments in offshore funds, and the remaining two percent are Level 3 inputs. The Company recognizes transfers between levels at the end of each quarter.
In Level 2, the Company has an investment in an affiliated offshore fund, classified as trading, with a fair value of $998,000 and $786,000 as of June 30, 2014, and 2013, respectively, based on the net asset value per share, which invests in companies in the energy and natural resources sectors. The Company may redeem this investment on the first business day of each month after providing a redemption notice at least forty-five days prior to the proposed redemption date.
In addition, the Company has investments in corporate debt securities, classified as available-for-sale, of $1.1 million as of June 30, 2014, categorized as Level 2 which the Company valued in accordance with the evaluated price supplied by an independent service.
The Company also had a Level 2 investment in an affiliated offshore fund with a fair value of $4.7 million as of June 30, 2013, classified as available-for-sale, which invested in dividend-paying equity and debt securities of companies located around the world. The fund liquidated in November 2013, and the Company received the fund’s underlying investments as a non-taxable redemption-in-kind.
The corporate debt in Level 3 is valued based on review of similarly structured issuances in similar jurisdictions. At June 30, 2014, the Level 3 corporate debt is valued at cost, which approximates fair value as a result of the Company’s review of similarly structured issuances in comparable jurisdictions.
At March 31, 2014, approximately $385,000 in investments in private and venture capital securities were transferred out of available-for-sale Level 3 assets and classified as other investments.
The following table is a reconciliation of investments recorded at fair value for which unobservable inputs (Level 3) were used in determining fair value during the years ended June 30, 2014, and 2013:

Investment Management and Other Fees	'
	INVESTMENT MANAGEMENT AND OTHER FEES
	The Company serves as investment adviser to USGIF and receives a fee based on a specified percentage of net assets under management.
	The advisory agreement for the equity funds within USGIF provides for a base advisory fee that is adjusted upwards or downwards by 0.25 percent if there is a performance difference of 5 percent or more between a fund’s performance and that of its designated benchmark index over the prior rolling 12 months. For the years ended June 30, 2014, 2013, and 2012, the Company realized a decrease in its base advisory fee of $815,000; $133,000; and $2.2 million; respectively.
	The following changes were made during the current fiscal year to the mutual funds the Company manages: (1) the Global Emerging Markets Fund liquidated on October 31, 2013, (2) the MegaTrends Fund was reorganized into the Holmes Growth Fund (renamed Holmes Macro Trends Fund), (3) the Tax Free Fund was reorganized into the Near-Term Tax Free Fund, (4) the U.S. Government Securities Savings Fund changed from a money market fund to the U.S. Government Securities Ultra-Short Bond Fund, and (5) the U.S. Treasury Securities Cash Fund was liquidated on December 27, 2013.
	The Company agreed to contractually limit the expenses of the Near-Term Tax Free Fund through December 2014. The Company has voluntarily waived or reduced its fees and/or agreed to pay expenses on the remaining funds. These caps will continue on a voluntary basis at the Company’s discretion. The aggregate fees waived and expenses borne by the Company were $2.4 million; $3.3 million; and $3.1 million; for the years ended June 30, 2014, 2013, and 2012, respectively.
	Prior to the U.S. Treasury Securities Cash Fund liquidation and the Government Fund conversion, the Company voluntarily agreed to waive fees and/or reimburse these funds to the extent necessary to maintain the respective fund’s yield at a certain level as determined by the Company (Minimum Yield). The above waived fees include fees waived and/or expenses reimbursed for these funds as a result of this agreement totaling $583,000 for the year ended June 30, 2014.
	The Company may recapture any fees waived and/or expenses reimbursed to maintain Minimum Yield within three years after the end of the funds’ fiscal year of such waiver and/or reimbursement to the extent that such recapture would not cause the funds’ yield to fall below the Minimum Yield. Thus, $737,000 of the waiver for the Government Fund is recoverable by the Company through December 31, 2014; $510,000 through December 31, 2015; and $498,000 through December 31, 2016. The U.S. Treasury Securities Cash Fund also had waivers subject to future recapture; however, because the fund was liquidated in December 2013, there will be no recapture. Management cannot predict the impact of the waivers due to the number of variables and the range of potential outcomes.
	In addition, effective December 2013, the Funds’ board of trustees increased the administrative services fees paid to the Company from an annual rate of 0.08 percent to 0.10 percent per investor class and from 0.06 percent to 0.08 percent per institutional class of each Fund, based on average daily net assets, plus $10,000 per Fund.
	In connection with obtaining and/or providing administrative services to the beneficial owners of USGIF through broker-dealers, banks, trust companies and similar institutions which provide such services, the Company receives shareholder services fees at an annual rate of up to 0.20 percent of the value of shares held in accounts at the institutions. The Company receives distribution and administrative services fees from USGIF based on average net assets.
	The Company’s Board of Directors formally agreed on August 23, 2013, to exit the transfer agency business so that the Company could focus more on its core strength of investment management. USSI served as transfer agent to USGIF until conversion to a new transfer agent on December 9, 2013. Before the conversion, USSI received fees based on the number of shareholder accounts, transaction and activity-based fees and certain miscellaneous fees. The transfer agency fees are included in “discontinued operations” in the Consolidated Statements of Operations.
	The Company provided advisory services to three offshore clients and received a monthly advisory fee based on the net asset values of the clients and performance fees based on the overall increase in net asset values, if any. One of the offshore funds liquidated in November 2013. The contracts between the Company and the offshore clients expire periodically, and management anticipates that its remaining offshore clients will renew the contracts. The Company recorded advisory and performance fees from these clients totaling $190,000 and $4,000 for the year ended June 30, 2014; $299,000 and $19,000 for the year ended June 30, 2013; and $352,000 and $6,000 for the year ended June 30, 2012, respectively.

	Dividends
	The monthly dividend of $0.005 is authorized through December 31, 2014, and will be considered for continuation at that time by the Board of Directors. 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. On a per share basis, the holders of the class C common stock and the nonvoting class A common stock participate equally in dividends as declared by the Company’s Board of Directors.
	Share Repurchase Plan
	The Board of Directors approved a share repurchase program on December 7, 2012, authorizing the Company to 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, 2013. On December 12, 2013, the Board of Directors renewed the repurchase program for calendar year 2014. The total amount of shares that may be repurchased in 2014 under the renewed program is $2.75 million. The acquired shares may be used for corporate purposes, including shares issued to employees in the Company’s stock-based compensation programs. As of June 30, 2014, there remains approximately $2.57 million available for repurchase under this authorization.
	During fiscal years 2014 and 2013, the Company repurchased 93,351 and 55,052, respectively, of its class A shares on the open market using cash of $289,000 and $174,000, respectively. To date, the Company has repurchased a total of 148,403 class A shares under the repurchase program using cash of $463,000. The Company did not repurchase any of its class A common stock during fiscal year 2012.
	Other Activity
	The Company did not grant any shares of class A common stock to employees during fiscal year 2014 and 2013. During fiscal year 2012, the Company granted 15,600 shares of class A common stock to certain employees at a weighted average fair value on grant date of $4.73. Grants vest immediately after issuance.
	The Company granted 3,600; 3,600; and 3,600 shares of class A common stock at a weighted average fair value of $3.07, $4.16, and $6.65 to its non-employee directors in fiscal years 2014, 2013, and 2012, respectively. Grants vest immediately after issuance.
	Shareholders of class C shares are allowed to convert to class A. During fiscal years 2014, 2013, and 2012, 1,340; 2,516; and 60 shares, respectively, were converted from class C to class A. Conversions are one class A share for one class C share and are recorded at par value. There are no restrictions or requirements to convert.
	Stock-based compensation
	In November 1989, the Board of Directors adopted the 1989 Non-Qualified Stock Option Plan (“1989 Plan”), amended in December 1991, which provides for the granting of options to purchase 1,600,000 shares of the Company’s class A common stock to directors, officers and employees of the Company and its subsidiaries. Options issued under the 1989 Plan vest six months from the grant date or 20 percent on the first, second, third, fourth, and fifth anniversaries of the grant date. Options issued under the 1989 Plan expire ten years after issuance. As of June 30, 2014, there were no options outstanding under the 1989 Plan.
	In April 1997, the Board of Directors adopted the 1997 Non-Qualified Stock Option Plan (“1997 Plan”), which provides for the granting of stock appreciation rights (SARs) and/or options to purchase 400,000 shares of the Company’s class A common stock to directors, officers, and employees of the Company and its subsidiaries. Options issued under the 1997 Plan expire ten years after issuance. No options were granted in fiscal years 2014 and 2013. One option for 5,000 shares was granted in fiscal year 2012 with a fair value, net of tax, of $8,000 and was to vest over five years with 20 percent vesting on each anniversary date. This option was forfeited in fiscal year 2014.
	The estimated fair value of options granted is amortized to expense over the options’ vesting period. The fair value of these options is estimated at the date of the grant using a Black-Scholes option pricing model with the following assumptions for the option granted in fiscal year 2012: expected volatility factor based on historical volatility of 49.9 percent, risk-free interest rate of 2.4 percent and an expected life of 5.67.
	Stock option transactions under the various employee stock option plans for the past three fiscal years are summarized below:

	INCOME TAXES
	The Company and its non-Canadian subsidiaries file a consolidated federal income tax return. 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. At June 30, 2014, the current deferred tax asset primarily consists of temporary differences in the deductibility of prepaid expenses, accrued liabilities and unrealized gains on trading securities. The long-term deferred tax asset is composed primarily of unrealized losses and other than temporary impairments on available-for-sale securities and capital loss carryovers.
	For federal income tax purposes at June 30, 2014, the Company has capital loss carryovers of approximately $754,000 expiring in fiscal year 2019. The Company also has charitable contribution carryovers of approximately $68,000 expiring in fiscal year 2018 and $34,000 expiring in fiscal year 2019.
	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 June 30, 2014 and 2013, a valuation allowance of $35,000 and $27,000, respectively, was included related to the charitable contribution carryover. No valuation allowance was included at June 30, 2012.

	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.
	During the normal course of business, the Company may be subject to claims, legal proceedings, and other contingencies. 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. Management believes that any liability in excess of these accruals upon the ultimate resolution of these matters will not have a material adverse effect on the consolidated financial statements of the Company.
	The Board of Directors has authorized a monthly dividend of $0.005 per share through December 2014, at which time it will be considered for continuation by the Board of Directors. 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. The total amount of cash dividends to be paid to class A and class C shareholders from July 2014 to December 2014 will be approximately $463,000.

Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]	'
Principles of Consolidation	'
	Principles of Consolidation. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries: USSI, USGB, USGG, USBERM and USCAN.
	In addition, effective June 1, 2014, the Company, through USCAN, completed its purchase of an additional 15 percent interest in Galileo from the company’s founder, Michael Waring. This additional investment brings USCAN’s ownership to 65 percent of the issued and outstanding shares of Galileo and represents a controlling interest of Galileo. With the additional investment, the Company expects to increase its presence in Canada. The non-controlling interest in this subsidiary is included in “non-controlling interest in subsidiary” in the equity section of the Consolidated Balance Sheets. See Note 3 Business Combination for additional information. After the purchase of the additional interest, Galileo changed its fiscal year end from December 31 to June 30, effective June 30, 2014, to correspond to the Company’s year end. This change was treated as a change in accounting principle.
	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 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 6 Investment Management and Other Fees 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.
	Prior to March 31, 2014, the Company classified investments in private and venture capital companies as available-for-sale Level 3 securities. Since these equity investments do not have readily determinable fair values, these investments should have been classified as “other investments” on the Consolidated Balance Sheets and accounted for under the cost method of accounting rather than at fair value. The Company determined that the difference between the fair value and the value using the cost method of accounting for these securities is not material to “accumulated other comprehensive income (loss)” or “other comprehensive income (loss)” and did not affect net income or earnings per share. To correct this balance sheet misclassification, the Company has reclassified $385,000 of investments as “other investments” on the face of the Consolidated Balance Sheets at cost adjusted for impairments. This reclassification was not material to “accumulated other comprehensive income (loss)” or “other comprehensive income (loss)” and did not affect net income or earnings per share.
	All significant intercompany balances and transactions have been eliminated in consolidation. Certain amounts have been reclassified for comparative purposes.
Business Combinations	'
	Business Combinations. Business combinations are accounted for under the acquisition method of accounting. Results of operations of an acquired business are included from the date of acquisition. Management estimates the fair value of the acquired assets, including identifiable intangible assets, assumed liabilities, and non-controlling interest in the acquiree based on their estimated fair values as of the date of acquisition. Any excess acquisition date fair value of the consideration transferred over fair value of the acquired net assets, if any, is recorded as “goodwill” on the Consolidated Balance Sheets. Any excess fair value of the acquired net assets over the acquisition date fair value of the consideration transferred is recorded as a gain on the Consolidated Statements of Operations.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents. Cash and cash equivalents include highly liquid investments with original maturities of three months or less.
Investments	'
	Investments. The Company classifies its investments based on intent at the time of purchase and reevaluates such designation as of each reporting period date. The Company records security transactions on trade date. Realized gains (losses) from security transactions are calculated on the first-in/first-out cost basis, unless otherwise identifiable, and are recorded in earnings on the date of sale.
	Trading Securities. Securities that are purchased and held principally for the purpose of selling in the near term are classified as trading securities and reported at fair value. Unrealized gains and losses on these securities are included in Investment income (loss).
	Held-to-Maturity Securities. Investments in debt securities that are purchased with the intent and ability to hold until maturity are classified as held-to-maturity and measured at amortized cost. The Company currently has no investments in held-to-maturity securities.
	Available-for-sale Securities. Investments that are neither trading securities nor held-to-maturity securities and for which the Company does not have significant influence are classified as available-for-sale securities and reported at fair value. Unrealized gains and losses on these available-for-sale securities are excluded from earnings, reported net of tax as a separate component of shareholders’ equity, and recorded in earnings on the date of sale.
	The Company evaluates its available-for-sale investments for other-than-temporary decline in value on a periodic basis. This may exist when the fair value of an investment security has been below the current value for an extended period of time. When a security in the Company’s investment portfolio has an unrealized loss in fair value that is deemed to be other than temporary, the Company reduces the book value of such security to its current fair value, recognizing the credit related decline as a realized loss in the Consolidated Statements of Operations and a revised GAAP cost basis for the security is established. For available-for-sale securities with declines in value deemed other than temporary, the unrealized loss recorded net of tax in accumulated other comprehensive income (loss) is realized as a charge to net income.
	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. These equity investments are accounted for under the cost method of accounting and evaluated for impairment. The Company considers many factors in determining impairment, including the severity and duration of the decline in value below cost, the Company’s interest and ability to hold the security for a period of time sufficient for an anticipated recovery in value, and the financial condition and specific events related to the issuer.
Equity Method Investments (Investment in Galileo)	'
	Equity Method Investments (Investment in Galileo). 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 Company’s proportional share of investee’s underlying net income or loss is recorded as a component of “other income” 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. No impairment was recognized for the Company’s equity method investment during the years presented. No investments were held at June 30, 2014, that are accounted for using the equity method. See Note 3 Business Combination for further information.
Fair Value of Financial Instruments	'
	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 because of the short maturity of the instruments.
Receivables	'
	Receivables. Receivables consist primarily of monthly advisory and other fees owed to the Company by USGIF as well as receivables related to offshore investment advisory fees. Receivables also include advisory fees owed to Galileo by the funds and clients it manages. Management considers various factors including current sales amounts, historical charge-offs and specific accounts identified as high risk. Uncollectible accounts receivable, if any, are charged against the allowance for doubtful accounts when all reasonable efforts to collect the amounts due have been exhausted. The Company had no allowance for doubtful accounts as of June 30, 2014, and 2013.
Property and Equipment	'
	Property and Equipment. Fixed assets are recorded at cost. Other than as noted below, 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. Galileo fixed assets, consisting of furniture, equipment and leasehold improvements, are depreciated over 2 to 5 years.
Impairment of Long-Lived Assets	'
	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 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.
Intangible Asset	'
	Intangible Asset. An intangible asset, consisting of a non-compete agreement, acquired in connection with the acquisition of Galileo shares effective June 1, 2014, is recorded at fair value determined using a discounted cash flow model as of the date of acquisition. The discounted cash flow model included various factors to project future cash flows expected to be generated from the asset, including: (1) an estimated rate of change for underlying managed assets; (2) expected revenue per managed assets; (3) incremental operating expenses; and (4) a discount rate. Management estimates a rate of change for underlying managed assets based on an estimated net redemption or sales rate. Expected revenue per managed assets and incremental operating expenses of the acquired assets are generally based on contract terms.
	The Company has determined that the non-compete agreement has a finite useful life. The Company will amortize this finite-lived identifiable intangible asset on a straight-line basis over its estimated useful life, currently expected to be approximately 2 years. Management periodically evaluates the remaining useful lives and carrying values of intangible assets to determine whether events and circumstances indicate that a change in the useful life or impairment in value may have occurred. Indicators of impairment monitored by management include a decline in the level of managed assets, changes to contractual provisions underlying the intangible assets and reductions in underlying operating cash flows. Should there be an indication of a change in the useful life or impairment in value of the finite-lived intangible asset, the Company compares the carrying value of the asset and its related useful life to the projected discounted cash flows expected to be generated from the underlying managed assets over its remaining useful life to determine whether impairment has occurred. If the carrying value of the asset exceeds the discounted cash flows, the asset is written down to its fair value determined using discounted cash flows.
Non-Controlling Interests	'
	Non-Controlling Interests. The Company reports “non-controlling interest in subsidiary” as equity, separate from parent’s equity, on the Consolidated Balance Sheets. In addition, the Company’s Consolidated Statements of Operations includes “net income (loss) attributable to non-controlling interest.”
Treasury Stock	'
	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.
Stock-Based Compensation	'
	Stock-Based Compensation. Stock-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.
Income Taxes	'
	Income Taxes. The Company and its subsidiaries file a consolidated federal income tax return. 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. As of June 30, 2014, the Company did not have any accrued interest or penalties related to uncertain tax positions. The tax years from 2010 through 2013 remain open to examination by the tax jurisdictions to which the Company is subject.
Revenue Recognition	'
	Revenue Recognition. The Company earns substantially all of its revenues from advisory, distribution services, and administrative fees that are calculated as a percentage of assets under management and are recorded as revenue as services are performed. Offshore advisory client contracts provide for monthly management fees, in addition to performance fees. The advisory contract for the equity funds within USGIF provides for a performance fee on the base advisory fee that are calculated and recorded monthly. Shareholder services fees are based on the assets of the funds held through institutions. Revenue shown on the Consolidated Statements of Operations is net of fee waivers.
Dividends and Interest	'
	Dividends and Interest. Dividends are recorded on the ex-dividend date, and interest income is recorded on an accrual basis. Both dividends and interest income are included in investment income.
Advertising Costs	'
	Advertising Costs. The Company expenses advertising costs as they are incurred. Certain sales materials, which are considered tangible assets, are capitalized and then expensed during the period in which they are distributed. Net advertising expenditures were $615,000; $862,000; and $1.2 million during fiscal years 2014, 2013, and 2012, respectively.
Foreign Exchange	'
	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 these translations are excluded from income and are recorded in “accumulated other comprehensive income (loss)” on the Consolidated Balance Sheets. 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 “investment income (loss)” on the Consolidated Statements of Operations.
Use of Estimates	'
	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	'
	Earnings Per Share. The Company computes and presents earnings per share attributable to U.S. Global Investors, Inc. in accordance with ASC 260, Earnings Per Share. Basic earnings per share (“EPS”) excludes dilution and is computed by dividing net income (loss) attributable to U.S. Global Investors, Inc. 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.
Accumulated Other Comprehensive Income (Loss)	'
	Accumulated Other Comprehensive Income (Loss). Accumulated other comprehensive income (loss) (“AOCI”), net of tax is reported in the Consolidated Balance Sheets and the Consolidated Statements of Shareholders’ Equity and includes the unrealized gains and losses on securities classified as available-for-sale and foreign currency translation adjustments.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In July 2013, the FASB issued Accounting Standard Update (“ASU”) No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11”). ASU 2013-11 became effective for the Company on July 1, 2014. Management is evaluating the ASU and its potential impact on the financial statements.
	In April 2014, the FASB issued ASU No. 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 will become effective for the Company on July 1, 2015. Management is evaluating the ASU and its potential impact on the financial statements.
	In May 2014, the FASB issued ASU No. 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, 2016, 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 2017.
