Investment Management And Other Fees [Abstract]
Investment Management And Other Fees [Text Block]	NOTE 4. INVESTMENT MANAGEMENT AND OTHER FEES The Company serves as investment adviser to U.S. Global Investors Funds (“USGIF” or the “Funds”) and receives a fee based on a specified percentage of net assets under management. The Company recorded base advisory fees from USGIF totaling $879,000 and $1.8 million for the three and six months ended December 31, 2015, respectively, compared with $1.4 million and $3.3 million, respectively, for the corresponding periods in the prior fiscal year. 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 when 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 three and six months ended December 31, 2015, the Company realized a decrease in its base advisory fee of $70,000 and $238,000, respectively. For the corresponding periods in fiscal year 2015, base advisory fees were adjusted downward by $247,000 and $430,000, respectively. The Company has agreed to contractually limit the expenses of the Near-Term Tax Free Fund through April 2016. 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 for USGIF for the three and six months ended December 31, 2015, were $373,000 and $751,000, respectively, compared with $337,000 and $614,000, respectively, for the corresponding periods in the prior fiscal year. Prior to the U.S. Government Securities Ultra-Short Bond Fund (“Government Fund”) conversion in December 2013 to a non-money market fund, the Company voluntarily agreed to waive fees and/or reimburse the Government Fund to the extent necessary to maintain the respective fund’s yield at a certain level as determined by the Company (“Minimum Yield”). The Company may recapture any fees waived and/or expenses reimbursed to maintain the Minimum Yield within three years after the end of the fund’s fiscal year of such waiver and/or reimbursement. Thus, $498,000 of the waiver for the Government Fund is recoverable by the Company through December 31, 2016. The Company receives administrative service fees from USGIF based on the average daily assets. However, effective December 10, 2015, administrative service fees paid to the Company by USGIF changed from an annual rate of 0.10 percent, plus a base fee of $7,000 per fund, to 0.05 percent per investor class and from 0.08 percent to 0.04 percent per institutional class of each fund, based on average daily net assets. The Company no longer receives a flat base fee per fund. As of December 31, 2015, the Company had $345,000 of receivables from USGIF. The Company also serves as investment adviser to an exchange traded fund (“ETF’) client, U. S. Global Jets ETF, that commenced operations in April 2015. The Company receives a unitary management fee of 0.60 percent of average net assets and has agreed to bear all expenses of the ETF. The Company recorded ETF advisory fees totaling $73,000 and $143,000 for the three and six months ended December 31, 2015, respectively. The Company provides advisory services for two offshore clients and received advisory fees based on the net asset values of the clients and performance fees, if any, based on the overall increase in net asset values. The Company recorded advisory and performance fees from these clients totaling $22,000 and $44,000 for the three and six months ended December 31, 2015, and $32,000 and $79,000, respectively, for the corresponding periods in the prior fiscal year. Frank Holmes, CEO, serves as a director of the offshore clients. Galileo provides advisory services for clients in Canada and receives advisory fees based on the net asset values of the clients. Galileo recorded advisory fees from these clients totaling $293,000 and $623,000 for the three and six months ended December 31, 2015, respectively, and $519,000 and $1.2 million, respectively, for the corresponding period in the prior fiscal year.
