SUPPLEMENT TO THE PROSPECTUS DATED DECEMBER 24, 1997
===============================================================================
Delaware Pooled Trust, Inc. June 5, 1998
The performance of the G&I Emerging Markets Fund has been presented to provide
investors with additional information on which to base their investment
decision. Emerging markets investment performance can be volatile and should
be evaluated over a multi-year period. The performance of the G&I Emerging
Markets Fund is not the performance of The Emerging Markets Portfolio of DPT
and should not be considered as a substitute for the performance of The
Emerging Markets Portfolio of DPT. The performance of the G&I Emerging Markets
Fund should not be considered indicative of the past or future performance of
The Emerging Markets Portfolio of DPT.
The charts on the following pages contain certain additional performance
information. For a description of the differences between The Emerging Markets
Portfolio of DPT and the G&I Emerging Markets Fund, see Differences Between
Funds.
Differences Between Funds
- -------------------------------------------------------------------------------
The investment objective of The Emerging Markets Portfolio of DPT is identical
to the investment objective of the G&I Emerging Markets Fund and the two funds
invest in substantially similar securities. Investment strategies for the two
funds will be substantially similar; however, because of the nature of investors
in The Emerging Markets Portfolio of DPT, cash flows can be expected to be
substantial and irregular, while cash flows in the G&I Emerging Markets Fund
tend to be more regular and in smaller amounts. The differences in cash flows
may affect the timing of investment decisions, the relative speed with which
such decisions may be implemented, the investments held by each Fund from time
to time, and, consequently, performance. In addition, investments may be made
for each fund during varying market conditions.
Shares of each of The Emerging Markets Portfolio of DPT and the G&I Emerging
Markets Fund Institutional Class may be purchased and sold without the
imposition of a sales charge; however, investors in The Emerging Markets
Portfolio of DPT are subject to a purchase reimbursement fee and a redemption
reimbursement fee equal in each case to 0.75% (as a percentage of the dollar
amount purchased or redeemed). The reimbursement fees, which are paid directly
to The Emerging Markets Portfolio of DPT, are designed to reflect an
approximation of the brokerage and related transaction costs associated with the
investment of an investor's purchase amount or the disposition of assets to meet
redemptions, and to limit the extent to which The Emerging Markets Portfolio of
DPT and its existing shareholders would have to bear such costs. The G&I
Emerging Markets Fund does not assess reimbursement fees; therefore, all
transaction costs associated with purchases and redemptions are borne by the G&I
Emerging Markets Fund.
After giving effect to voluntary expense limitations described in each fund's
prospectus, the total operating expenses of The Emerging Markets Portfolio of
DPT during the current fiscal year are not expected to exceed 1.55% of the
average net assets of the Portfolio, compared to 1.70% for the Institutional
Class of the G&I Emerging Markets Fund. A component of the total operating
expenses is the investment management fee payable to Delaware International,
which is currently subject to a limit of 1.00% for The Emerging Markets
Portfolio of DPT compared to a maximum fee of 1.25% for the G&I Emerging Markets
Fund.

Emerging Markets Fund (the "G & I Emerging Markets Fund") Institutional

or 5.5% annualized.
