Investments in stocks are subject to risk, including the possible loss of principal. Stocks of small-cap and micro-cap companies may be subject to additional risks. Companies with smaller market capitalizations tend to be at early stages of development with limited product lines, market access for products, financial resources, access to new capital, or depth in management. It may be difficult to obtain reliable information and financial data about these companies. Consequently, the securities of smaller companies may not be as readily marketable and may be subject to more abrupt or erratic market movements.

In attempting to track the performance of the Russell 2000 Index, the Fund may be more susceptible to adverse developments concerning a particular security, company or industry because the Fund’s index component generally will not use any defensive strategies to mitigate its risk exposure. Please see the prospectus for additional risks.
