Important Disclosures
An investor should consider the investment objectives, risks, charges and expenses of each fund carefully before investing. To obtain a fund’s Prospectus, which contains this and other information, contact your financial professional, call 1.888.622.1813 or visit SprottETFs.com. Read the Prospectus carefully before investing.
Exchange Traded Funds (ETFs) are considered to have continuous liquidity because they allow for an individual to trade throughout the day, which may indicate higher transaction costs and result in higher taxes when fund shares are held in a taxable account.
The funds are non-diversified and can invest a greater portion of assets in securities of individual issuers, particularly those in the natural resources and/or precious metals industry, which may experience greater price volatility. Relative to other sectors, natural resources and precious metals investments have higher headline risk and are more sensitive to changes in economic data, political or regulatory events, and underlying commodity price fluctuations. Risks related to extraction, storage and liquidity should also be considered.
Shares are not individually redeemable. Investors buy and sell shares of the funds on a secondary market. Only “authorized participants” may trade directly with the fund, typically in blocks of 10,000 shares.
