GLOBAL GROWTH SERIES
Supplement to Current Prospectus
As disclosed in the Trust's Prospectus, Foreign & Colonial Management Ltd.
("FCM") and its subsidiary, Foreign & Colonial Emerging Markets Limited
("FCEM"), have been retained by MFS to serve as sub-advisers to the series to
manage the assets of the series invested in foreign emerging market securities.
Effective September 1, 1999, MFS will assume all portfolio management
responsibilities for emerging market securities from FCM and FCEM for the
series, and the sub-investment advisory agreements pursuant to which FCM and
FCEM provide their services will terminate. Effective September 1, 1999, the
description of the manner in which foreign emerging markets securities are
managed is revised as follows:
Foreign Emerging Markets Managed by a committee of investment research
analysts. This committee includes investment
analysts employed by MFS and by MFS' foreign
branches and affiliates. This portion of the
series' assets is allocated among countries and
industries by the analysts acting together as
a group. Individual analysts are then
responsible for selecting what they view as the
securities best suited to meet each such series
investment objective within their assigned
geographic and industry responsibility.
The date of this Supplement is July 16, 1999.
