The Company also provides advisory services to SEC registered exchange traded funds (“ETFs”) and formerly provided advisory services to offshore clients. Until March 2020, the Company held a controlling interest in Galileo Global Equity Advisors Inc. (“Galileo”), a privately held Toronto-based asset management firm.

The Company has the following subsidiaries utilized primarily for corporate investment purposes: U.S. Global Investors (Bermuda) Limited (“USBERM”), incorporated in Bermuda, and U.S. Global Investors (Canada) Limited (“USCAN”). The Company created U.S. Global Indices, LLC, a Texas limited liability company, of which the Company is the sole member, to provide indexing services to exchange-traded funds managed by the Company.

U.S. Global formed U.S. Global Brokerage, Inc. (“USGB”) to provide distribution services to USGIF. USGB ceased operations in December 2015. On July 27, 2018, USGB was dissolved.

Effective March 2, 2020, the Company sold its shares in Galileo back to Galileo. Through the date of sale, Galileo was consolidated with the operations of the Company.

To limit the spread of the novel coronavirus (“COVID-19”), governments have taken various actions including the issuance of stay-at-home orders and social distancing guidelines, causing some businesses to suspend operations, disrupting the global supply chain, and creating a reduction in demand for many products. This has negatively affected global financial markets and has caused significant financial market depreciation, thus reducing certain of the Company’s assets under management (“AUM”), the revenue related to those assets, and returns on corporate investments.

Should the negative effect on global financial markets continue for an extended period, there could be an adverse material financial impact on the Company’s results of operations, cash flows and financial position.
