SUPPLEMENT TO THE PROSPECTUS OF
DEAN WITTER VARIABLE INVESTMENT SERIES DATED FEBRUARY 11, 1994
The seventh paragraph under the section of the Prospectus entitled "The
Fund and its Management" is revised to reflect that, effective May 1, 1994,
the Trustees of the Fund have amended the Fund's Investment Management
Agreement to reduce the compensation received by the Investment Manager under
the Agreement in respect of each of the Dividend Growth Portfolio and the
Utilities Portfolio for assets exceeding $500 million, so that the
compensation under the Agreement in respect of these Portfolios is calculated
daily by applying the following annual rates to the assets of each of these
Portfolios determined as of the close of each business day: 0.625% of the
portion of the daily net assets of the Dividend Growth Portfolio up to $500
million and 0.50% of the portion of the daily net assets of that Portfolio
exceeding $500 million; and 0.65% of the portion of the daily net assets of
the Utilities Portfolio not exceeding $500 million and 0.55% of the portion
of the daily net assets of that Portfolio exceeding $500 million.
The subsection entitled "Portfolio Management" under the subsection
entitled "General Portfolio Techniques" in the section of the Prospectus
entitled "Investment Objectives and Policies" is revised to reflect that, on
April 1, 1994, Jeremy G. Lodwick became the primary portfolio manager of the
European Growth Portfolio. Mr. Lodwick is a Director of the Sub-Adviser and
has been managing portfolios consisting of equity securities issued by
European issuers for the Sub-Adviser since January, 1992; prior thereto, he
was employed by the Sub-Adviser in another capacity.
