**Calculation is a 90 day rolling return

Mutual fund investing involves risk, including loss of principal. For specific risk associated with each investment choice, please click on the fund name and refer to the "Investment Considerations" or "Investor Profile."

Bond funds will tend to experience smaller fluctuation in price than stock funds. The return of principal in bond funds is not guaranteed. The principal value of a bond falls when interest rates rise and rise when interest rates fall. During periods of rising interest rates, the value of a bond investment is at greater risk than during periods of stable or falling rates. Bond funds have the same interest rate, inflation, reinvestment, credit and prepayment risks associated with the underlying bonds in the portfolio.

Tax Exempt Funds: The fund's income may be subject to certain state and local taxes and, depending on your tax status, the federal alternative minimum tax.

The recent growth rate in the stock market has helped to produce short-term returns for some asset classes that are not typical and may not continue in the future. Because of ongoing market volatility, fund performance may be subject to substantial short-term changes.
