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.

An investment in the fund could lose money over short or even long periods. You should expect the fund’s share price and total return to fluctuate within a wide range, like the fluctuations of the overall bond market. The fund’s performance could be hurt by:

  • Interest rate risk: The chance that bond prices overall will decline because of rising interest rates.
  • 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.
  • Call risk: The chance that during periods of falling interest rates, the issuer of a bond will repay—or call—securities with higher coupons, or interest rates, before their maturity dates. Forced to reinvest the unanticipated proceeds at lower interest rates, the fund would experience a decline in income and lose the opportunity for additional price appreciation associated with falling interest rates.
  • Index sampling risk: The chance that the securities selected for the fund will not provide investment performance matching that of the index.
