About our options  



Purchase fee:

A fee charged by some mutual funds when an investor buys shares. This fee is not a sales charge or load because it is paid directly to the fund to offset the costs of trading certain securities.

Redemption fee:

A fee charged by some mutual funds when an investor sells shares. A redemption fee differs from a back-end load because the money is paid back into the fund. Many funds charge redemption fees only when shares are bought and then sold within a specific period of time, generally in an effort to discourage market-timing and short-term trading. Some brokers also charge their clients redemption fees for the sale of securities.

* Credit-quality ratings are measured on a scale that generally ranges from AAA (highest) to D (lowest). “NR” is used to classify securities for which a rating is not available. U.S. Treasury, U.S. Agency, and U.S. Agency mortgage-backed securities appear under “U.S. Government.” Credit-quality ratings for each issue are obtained from Barclays using ratings derived from Moody’s Investors Service, Fitch Ratings, and Standard & Poor’s. When ratings from all three agencies are available, the median rating is used. When ratings are available from two of the agencies, the lower rating is used. When one rating is available, that rating is used.

Risk and volatility are based on the share class with the earliest inception date.

Risk measures are calculated from trailing 36-month fund returns relative to the associated benchmarks.

The fund is designed for investors with a low tolerance for risk; however, the fund’s performance could be hurt by:

  • Interest rate risk: The chance that bond prices overall will decline because of rising interest rates. Interest rate risk should be low for the fund because it invests primarily in short-term bonds, whose prices are much less sensitive to interest rate changes than are the prices of long-term bonds.
  • Income risk: The chance that the fund’s income will decline because of falling interest rates.
  • Credit risk: The chance that a bond issuer will fail to pay interest and principal in a timely manner, or that negative perceptions of the issuer’s ability to make such payments will cause the price of that bond to decline.
  • Index sampling risk: The chance that the securities selected for the fund, in the aggregate, will not provide investment performance matching that of the index. Index sampling risk for the fund should be low.
