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.


The fund assesses a 0.50% fee ($5.00 per $1,000) on purchases. The fee is paid directly to the fund and therefore is not considered a load.

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.

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 an extremely wide range, much more than the fluctuations of the overall bond market.

  • Interest rate risk: The chance that bond prices overall will decline because of rising interest rates. Interest rate risk is expected to be extremely high for the fund because it invests mainly in zero-coupon long-term bonds, which have prices that are even more sensitive to interest rate changes than are coupon-bearing bonds of similar maturity.
  • 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.
