Guggenheim Investments

Guggenheim Investments represents the investment management businesses of Guggenheim Partners, LLC, which consist of investment managers with approximately $127 billion in combined total assets.² Collectively, Guggenheim Investments has a long, distinguished history of serving institutional investors, ultra-high-net-worth individuals, family offices and financial intermediaries.

Shares of each CurrencyShares^® Trust may not be suitable for all investors. The value of the shares of each CurrencyShares^® Trust relates directly to the value of the foreign currency held by the particular Trust. This creates a concentration risk associated with fluctuations in the price of the applicable foreign currency. Accordingly, a decline in the price of that currency will have an adverse effect on the value of the shares of the particular CurrencyShares^® Trust. Factors that may have the effect of causing a decline in the price of a foreign currency include national debt levels and trade deficits, domestic and foreign inflation rates, domestic and foreign interest rates, investment and trading activities of institutions and global or regional political, economic or financial events and situations. Shares of each CurrencyShares^® Trust can be bought and sold through a broker; as such, investors may be required to pay brokerage commissions in connection with a purchase or sale. There can be no assurance that an active trading market for the shares of any CurrencyShares^® Trust will develop or be maintained. For a more complete discussion of risk factors applicable to each CurrencyShares^® Trust, carefully read the particular Trust’s prospectus.

The CurrencyShares^® Australian Dollar (FXA) Trust, CurrencyShares^® British Pound Sterling (FXB) Trust, CurrencyShares^® Canadian Dollar (FXC) Trust, CurrencyShares^® Chinese Renminbi (FXCH) Trust, CurrencyShares^® Euro (FXE) Trust, CurrencyShares^® Japanese Yen (FXY) Trust, CurrencyShares^® Swedish Krona (FXS) Trust, CurrencyShares^® Swiss Franc (FXF) Trust (each a “Trust” and collectively, the “Trusts”) has filed a registration statement (including a prospectus) with the SEC for the offerings to which this communication relates. Before you invest in the shares of a Trust, you should read the prospectus in the registration statement and other documents the Trust has filed with the SEC for more complete information about the Trust and its offering.
