DIMENSIONAL INVESTMENT GROUP INC.
RWB/DFA U.S. High Book to Market Portfolio
RWB/DFA Two-Year Corporate Fixed Income Portfolio
RWB/DFA Two-Year Government Portfolio
SUPPLEMENT DATED OCTOBER 13, 1997
TO THE PROSPECTUS DATED MARCH 28, 1997
The Board of Directors of Dimensional Investment Group Inc. (the
"Fund") have approved separate investment advisory agreements ("Advisory
Agreements") with Dimensional Fund Advisors Inc. ("Advisor") for the
management of the assets of RWB/DFA Two-Year Corporate Fixed Income Portfolio
("Corporate Portfolio") and RWB/DFA Two Year Government Portfolio
("Government Portfolio"), subject to the approval of the shareholders of
the respective Portfolios. If shareholders of the Portfolios vote to approve
the Advisory Agreements, the Corporate Portfolio will redeem its entire
investment in the DFA Two-Year Corporate Fixed Income Series of The DFA
Investment Trust Company (the "Trust") and the Government Portfolio will
redeem its entire investment in the DFA Two-Year Government Series of the
Trust. In order to satisfy this redemption request, it is contemplated that
each Series would then distribute its assets (consisting of portfolio
securities and cash) to its corresponding Portfolio. Following such
redemption, each Portfolio will then seek to achieve its investment objective
by investing directly in a portfolio of securities in accordance with its
investment policies and restrictions. The terms of the Advisory Agreements are
substantially the same as the terms of the existing investment management
agreements between the Advisor and each Series, and provide for the same rate
of management fee. If approved by the shareholders of the Portfolios, it is
expected that the Advisory Agreements will become effective on or about
November 30, 1997.
