SUPPLEMENT TO THE PROSPECTUS OF
DEAN WITTER HIGH INCOME SECURITIES DATED JUNE 16, 1997
On June 30, 1997, the Board of Trustees of Dean Witter High Income
Securities (the "Fund") approved an Agreement and Plan of Reorganization
between the Fund and Dean Witter High Yield Securities Inc. ("High Yield"),
pursuant to which the assets of the Fund would be combined with those of High
Yield and shareholders of the Fund would become shareholders of High Yield,
receiving shares of High Yield equal to the value of their holdings in the
Fund (the "Reorganization"). On July 28, 1997, High Yield will begin offering
its shares in multiple classes, each with different distribution arrangements
and sales charges. Class B shares will be offered at net asset value without
an initial sales charge but will under most circumstances be subject to a
declining contingent deferred sales charge ("CDSC"). Shareholders of the Fund
will receive Class B shares of High Yield in connection with the
Reorganization.
Shares of the Fund purchased prior to the Reorganization by trusts for
which Dean Witter Trust Company ("DWTC") or Dean Witter Trust FSB ("DWTFSB")
provides discretionary trustee services will convert to Class A shares of
High Yield shortly after the Reorganization. The CDSC will not be applicable
to such shares. Class A shares of High Yield are subject to lower ongoing
distribution fees than those of Class B.
The Reorganization is subject to the approval of shareholders of the Fund.
A proxy statement formally detailing the proposal and the reasons for the
Trustees' action, as well as information concerning High Yield, will be
distributed to shareholders of the Fund.
The Board of Trustees of the Fund also approved expanding the category of
retirement plans that are eligible for a waiver of any applicable CDSC, which
category currently pertains only to certain 401(k) plans, to include
redemptions of shares of the Fund held by all employer-sponsored plans
qualified under Internal Revenue Code Section 401(a) that offer investment
companies managed by Dean Witter InterCapital Inc., the Fund's investment
manager, or its subsidiary, Dean Witter Services Company Inc., as
self-directed investment alternatives and for which DWTC or DWTFSB serves as
Trustee or the 401(k) Support Services Group of Dean Witter Reynolds Inc.
serves as recordkeeper ("Eligible Plan"), provided that either (a) the plan
continues to be an Eligible Plan after the redemption or (b) the redemption
is in connection with the complete termination of the plan involving the
distribution of all plan assets to participants.
