There are risks involved with investing in ETFs including possible loss of money. Shares are not actively managed and are subject to risk similar to stocks and covered call options, as well as those risks related to short selling and margin maintenance. Ordinary brokerage commissions apply.

Small- and Medium-Sized Company Risk Information

An investment in securities of small- and medium-sized companies involves greater risk than is customarily associated with investing in more established, larger sized companies.

Foreign Risk Information

An investment in the securities of non-U.S. issuers involves risks beyond those associated with investments in U.S. securities, including, but not limited to: greater market volatility, the availability of less reliable financial information, higher transactional and custody costs, taxation by foreign governments, decreased market liquidity, political instability, negative impact of changes in currency exchange rates or foreign governmental regulation, currency risk, fluctuation due to changes in interest rates, effects of monetary policies issued by the United States, foreign governments, central banks or supranational entities and currency controls or other national or global political economic developments, among others.

Non-Diversified Fund Risk Information

The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund.

Industry and Sector Risk

When a Fund is focused in a specific industry or sector, it presents greater risks than if it were broadly diversified over numerous industries and sectors of the economy. There are additional risks associated with investing in companies involved in the steel, gold and precious metals, coal and agriculture industries. Please read the prospectus for a summary of these risks pertaining to each industry or sector.
