About Risk

Mutual funds that invest in bonds can lose their value. When interest rates rise, bond prices usually fall and vice versa. Credit risk (the risk that the issuer or borrower will fail to make timely payments of interest and/or principal) is heightened for lower rated or higher yielding fixed-income securities and lower rated borrowers. In addition, lower-rated debt securities may be subject to greater price volatility
High yield securities are subject to a high degree of market and credit risk. In addition, the secondary market for these securities may lack liquidity which, in turn may adversely affect the value of these securities and the value of the fund
Foreign investments involve special risks including greater economic, political and currency fluctuation risks, which may be even greater in emerging markets

Past performance is no guarantee of future results.

¹ For further detail regarding Minimum Initial Investment, please see the fund prospectus.

² Unlike net expense ratio, gross expense ratio does not reflect any potential reimbursement/waiver of expenses, if any, as stated in the most recent Fund prospectus. Fund expenses and expense reductions are subject to change. Expense reductions are contractual; Class I shares are set to expire 1/31/2014, Class R on 1/31/2014 . Investors should consult the most recent prospectus for more detailed information.

³Unsubsidized 30-day SEC yield is calculated using the gross expenses of the fund. Gross expenses do not include any fee waivers or reimbursement.

The Barclays US Intermediate Government/Credit Bond Index includes securities which have a remaining maturity of 1-10 years and includes Treasuries (public obligations of the US Treasury that have remaining maturities of more than one year) and agencies (publicly issued debt of US Government agencies, quasi-federal corporations and corporate or foreign debt guaranteed by the US Government), as well as other publicly issued investment grade corporate and non-corporate debentures that meet specified maturity, liquidity, and quality requirements. Indexes are unmanaged and do not incur fees. It is not possible to invest directly in an index.

Lipper and Morningstar rankings are based on total returns calculated by each ranking entity. Rankings do not take into account sales charges, if applicable, but include reinvestment of dividends and capital gains, if any.

Prior to the inception of Retail Class shares (5/28/10), performance is that of Institutional Class shares, restated to reflect the higher net expenses of Retail Class shares.

Total return assumes reinvestment of dividends and capital gains distributions, if any.

Performance data quoted represents past performance and is no guarantee of future results. Total return and value will vary and you may have a gain or loss when shares are sold. Current performance may be lower or higher than quoted. Returns include changes in share price and reinvestment of dividends and capital gains, if any.
