BOSTON PARTNERS BOND FUND
(INVESTOR CLASS)
OF
THE RBB FUND, INC.
SUPPLEMENT DATED JULY 30, 1998
TO THE PROSPECTUS DATED JANUARY 1, 1998
The following paragraph is added to the section entitled RISK FACTORS on
pages 5-7 of the Prospectus:
ASSET ALLOCATION
From time to time, the Fund may experience relatively large purchases or
redemptions due to asset allocation decisions made by the Adviser for clients
receiving Asset Allocation account management services involving investments in
the Fund. These transactions may have a material effect on the Fund, since
redemptions caused by reallocations may result in the Fund selling portfolio
securities, and purchases caused by reallocations may result in the Fund
receiving additional cash that it will have to invest. While it is impossible to
predict the overall impact of these transactions over time, there could be
adverse effects on portfolio management to the extent that the Fund may be
required to sell securities at times when it would not otherwise do so, or
receive cash that cannot be invested in an expeditious manner. These
transactions could also have tax consequences if the sale of securities results
in gains and could also increase transaction costs. The Adviser is committed to
minimizing the impact of such transactions on the Fund to the extent it is
consistent with pursuing the investment objectives of clients for which the
Adviser provides Asset Allocation account management services involving
investments in the Fund and monitors the impact of asset allocation decisions on
the Fund.
