Supplement to the May 1, 1997 Prospectus
The following language deletes and replaces in its entirety the
paragraph entitled "MFS/Foreign & Colonial International Growth and Income
Series" on the cover page of the current Prospectus:
MFS/Foreign & Colonial International Growth and Income Series will seek
capital appreciation and current income by investing, under normal market
conditions, at least 65% of its total assets in equity securities of issuers
whose principal activities are outside the U.S. (see page 23).
In addition, the following language deletes and replaces in its
entirety the language in the section entitled "(8) MFS/Foreign & Colonial
International Growth and Income Series ("International Growth and Income
Series")" on pages 23 and 24 of the current Prospectus:
The International Growth and Income Series' investment objective is to
seek capital appreciation and current income. The series seeks to achieve its
objective by investing primarily in equity securities of issuers whose principal
activities are outside the U.S. The series will invest, under normal market
conditions, at least 65% of its total assets (and generally expects to invest a
substantial portion of its total assets) in equity securities of foreign "blue
chip" companies and foreign growth companies. See "Investment Instruments and
Techniques - Foreign Growth Securities" below. The series considers a security
to be "blue chip" if the total equity market capitalization of the issuer is at
least U.S. $5 billion. It is expected that the series' equity securities will
include securities which pay relatively high current dividends.
The series may invest up to 10% of its net assets in securities of
issuers whose principal activities are located in emerging market countries. See
"Investment Instruments and Techniques - Emerging Market Securities" below.
