The value of utility stocks changes as long-term interest rates change. Funds investing in a single sector, such as utilities, may be subject to more volatility than funds that invest more broadly. The utilities industries can be significantly affected by government regulation, financing difficulties, supply or demand of services, or fuel and natural resources conservation.

The Fund's share price will fluctuate with changes in the market value of the Fund's portfolio securities. Stocks are subject to market, economic and business risks that cause their prices to fluctuate. When you sell Fund shares, they may be worth less than what you paid for them. Consequently, you can lose money by investing in the Fund.

Investors should consider the investment objectives, risks, sales charges and expense of the fund carefully before investing. The prospectus contains more complete information about this and other matters. The prospectus should be read carefully before investing.
