Choosing a Fund
Use our Risk/Reward spectrum to navigate your way to the mutual fund that is right for you.

If you're a conservative, income-oriented investor who wants higher current income than that generally offered by the U.S. Government Fund and you're willing to assume moderately more risk in exchange, you may find this Fund suitable. This Fund can also be an appropriate choice for investors who want to broaden and diversify their fixed income portfolio. Our experienced investment team's approach is to monitor and control the portfolio risk relative to the overall market while maintaining an average maturity within the portfolio between seven and 12 years.

Performance quoted represents past performance and does not guarantee future results. Investment return and principal value will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than that shown here.

The Advisor has agreed to reimburse certain expenses of the Fund. The contractual reimbursement arrangement is expected to continue until at least July 31, 2011. After this date, the contractual arrangements may be terminated if it is determined to be in the best interest of the Fund and its shareholders. In the absence of fee waivers, yield, total return, growth since inception and dividends would have been reduced. Total return is based on net change in NAV assuming reinvestment of distributions. The 30-day SEC yield more closely reflects the current earnings of the Fund than the total returns.

Bond Risk: Bond funds will tend to experience smaller fluctuations in value than stock funds. However, investors in any bond fund should anticipate fluctuations in price, especially for longer-term issues and in environments of rising interest rates.

Mortgage-Backed Securities Risk: Mortgage-backed investments involve risk of loss due to prepayments and, like any bond, due to default. Because of the sensitivity of mortgage-related securities to changes in interest rates, the Fund’s performance may be more volatile than if it did not hold these securities.

Barclays Capital U.S. Aggregate Bond Index is an unmanaged index of prices of U.S. dollar-denominated investment-grade fixed income securities with remaining maturities of one year and longer. It is not possible to invest directly in an index.

Quality Distribution: Credit quality ratings primarily originate from data compiled by Barclays Capital within their POINT model. They are based on the conservative average of Moody's, Standard & Poor's, and Fitch ratings. If ratings from all three rating agencies disagree, the model assigns the middle rating to the security. If two of the three agree, the model assigns the rating from those two to the security. If none of these three rating agencies has assigned a rating the Fund will assign a rating of NR (non-rated security). The ratings represent the rating agencies' opinions of the quality of the securities they rate. The ratings, expressed in Moody's nomenclature, range from Aaa ("judged to be of the highest quality, with minimal credit risk") to C ("the lowest rated class of bonds, typically in default, with little prospect for recovery of principal or interest"). Ratings are relative and subjective and are not absolute standards of quality.
