MFS/SUN LIFE SERIES TRUST
FOREIGN & COLONIAL EMERGING MARKETS EQUITY 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"), currently manage the assets of the series invested in foreign emerging
market securities, which constitute the primary investment focus of the series.
The following changes will take effect on December 1, 1999:
o 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.
o The series' name will change to "Emerging Markets Equity Series".
o The description of the manner in which foreign emerging markets
securities are managed, as contained in the Prospectus, will be
revised as follows:
The series is managed by a committee of investment research
analysts. This committee includes investment analysts not
only employed by MFS but also by MFS' foreign advisory
affiliates. The series' assets are 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 the series'
investment objective within their assigned geographic and
industry responsibility.
The date of this Supplement is November 18, 1999.
