For each fund with at least a three-year history, Morningstar calculates a Morningstar Rating based on a Risk-Adjusted Return measure that accounts for variation in a fund's monthly performance (including the effects of sales charges, loads and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. Within each asset class, the top 10%, the next 22.5%, 35%, 22.5%, and the bottom 10% receive 5, 4, 3, 2, or 1 star, respectively. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages.) Each fund is rated exclusively against U.S. domiciled funds. The Overall Morningstar Rating™ is based on the weighted average of the number of stars assigned to the fund's applicable time periods. In cases where the fund has changed investment categories, its historical information is given less weight. If the fund has been in existence at least 10 years, the 10-year rating accounts for 50%, the 5-year for 30%, and the 3-year for 20%. If the fund has been in existence at least 5 years, but less than 10 years, the 5-year rating accounts for 60% and the 3-year for 40%. If the fund has been in existence for 3 years, but less than 5 years, the 3-year rating accounts for 100%. Morningstar rankings may vary among share classes and are based on historical total returns, which are not indicative of future results.

Load-waived (LW) Class A share star ratings do not include any front-end sales load and are intended for those investors who have access to such purchase terms (e.g., plan participants of a defined contribution plan). Not all A share mutual funds for which Morningstar calculates a load-waived A share star rating may actually waive their front-end sales load. Therefore, Morningstar strongly encourages investors to contact their investment professional to determine whether they are eligible to purchase the A share without paying the front load.

Important Risk Considerations

The fund may not achieve its objective and/or you could lose money on your investment in the fund.

Investments in debt instruments may decline in value as the result of declines in the credit quality of the issuer, borrower, counterparty, underlying collateral, or changes in economic, political, issuer-specific, or other conditions. Certain types of debt instruments can be more sensitive to these factors and therefore more volatile. In addition, debt instruments entail interest rate risk (as interest rates rise, prices usually fall), therefore the Fund's share price may decline during rising rate environments as the underlying debt instruments in the portfolio adjust to the rise in rates. Funds that consist of debt instruments with longer durations are generally more sensitive to a rise in interest rates than those with shorter durations. At times, and particularly during periods of market turmoil, all or a large portion of segments of the market may not have an active trading market. As a result, it may be difficult to value these investments and it may not be possible to sell a particular investment or type of investment at any particular time or at an acceptable price.

Investments in derivatives can be used to take both long and short positions, be highly volatile, result in leverage (which can magnify losses), and involve risks in addition to the risks of the underlying indicator(s) on which the derivative is based, such as counterparty and liquidity risk.

Investments in lower-quality debt instruments can be more volatile and have greater risk of default than higher-quality debt instruments.

The fund's performance could be more volatile than the performance of more diversified funds.

Mortgage-backed securities can be subject to prepayment and/or extension and therefore can offer less potential for gains and greater potential for loss.

U.S. government securities not supported as to the payment of principal or interest by the U.S. Treasury are subject to greater credit risk than are U.S. government securities supported by the U.S. Treasury.

Please see the prospectus for further information on these and other risk considerations.
