strategy.

*    Return after Taxes on Distributions and Sale of Fund Shares is higher than
     other return figures for the same period due to a capital loss occurring
     upon redemption resulting in an assumed tax deduction for the shareholder.

grade fixed-income measure comprised of three component indices, the U.S.
