The Fund’s returns will vary, and you could lose money by investing in the Fund. The Fund’s investments in obligations issued or guaranteed by U.S. Government agencies or instrumentalities may not be backed by the full faith and credit of the United States and may differ in the degree of support provided by the U.S. Government. As interest rates rise, bond prices will fall and bond funds become more volatile. The Fund is subject to credit risk. The Fund’s net asset value and total return may be adversely affected by the inability of the issuers of the Fund’s securities to make interest payments or payment at maturity. International investing involves special risk considerations, including currency fluctuations, lower liquidity, economic and political risk. Investing in emerging markets can increase these risks, including higher volatility and lower liquidity. The Fund’s investments in collateralized mortgage obligations are subject to prepayment and extension risk. Prepayment of high interest rate mortgage-backed securities during times of declining interest rates will tend to lower the return of the Fund and may even result in losses to the Fund if the prepaid securities were acquired at a premium. Slower prepayments during periods of rising interest rates may increase the duration of the Fund’s mortgage-backed securities and asset-backed securities and reduce their value. This is not a money market fund. Rule 144A securities are not registered for resale in the general securities market and may be classified as illiquid. It may not be possible to sell or otherwise dispose of illiquid securities both at the price and within a time period deemed desirable by the Fund.

The U.S. News Mutual Fund Score is produced using an equal weighting of the overall ratings provided by Morningstar, Lipper, Zacks, TheStreet.com, and Standard & Poor’s.

Individual fund rating systems are normalized to a 100-point scale based on point totals assigned to individual scoring systems. For Morningstar's and S&P's five-star ranking and Zacks five-point scale, each star or point awarded would receive 20 points. In TheStreet.com's A-to-E scale, a highly rated "A" fund would receive 100 points, while a low-rated "E" would receive 20 points. The five Lipper Leader categories are each worth a total of 20 points, giving 4 points to each 1-to-5 point scale assigned to each section of the Lipper rankings. The U.S. News score is calculated by dividing total points awarded according to the above system by the number data sources (5). The combined U.S. News Mutual Fund Score ranks funds numerically based on this score. Funds with identical scores to one decimal place are awarded the same numerical ranking.
Funds must be ranked by all five data sources to receive a U.S. News Mutual Fund Score.

The U.S. News Mutual Fund Score groups funds by their Morningstar fund category. However, some systems use different categorizations when ranking funds.
