Equity Real Estate Investment Trusts (REITs) may be affected by changes in the value of the underlying property owned by the trust, while mortgage REITs may be affected by the quality of any credit extended. This fund is subject to some of the risks associated with direct ownership of real estate, including market value declines, risks related to general and local economic conditions and increases in interest rates. This fund, however, does not own real estate directly.
