in the table above has been restated to reflect the current fees. Prior to
April 30, 1999, the investment adviser, Morgan Stanley Dean Witter Advisors
Inc., assumed all expenses of the Portfolio and waived the compensation
provided for the Portfolio in its management agreement with the Fund.

Debt Portfolios, the investment advisers have voluntarily agreed to waive
their investment advisory fees and to reimburse certain expenses of the
