MFS World Growth Fund
Supplement to Prospectus dated March 1, 1997
On September 8, 1997, certain changes will be made with respect to the
services provided by Foreign & Colonial Management Ltd. ("FCM") and its
subsidiary, Foreign & Colonial Emerging Markets Limited ("FCEM"), as
sub-advisers to the Fund. FCM and FCEM will continue to manage the portion of
the Fund's assets invested in emerging market equity securities; however,
representatives of FCM will no longer serve on the committee of research
analysts which oversees the portion of the Fund's assets invested in foreign
developed markets. FCM has agreed to waive the sub-investment advisory fee it
receives from MFS with respect to the Fund from 1% per annum of the Fund's
average net assets managed by FCM to 0.65% per annum of the Fund's average daily
net assets managed by FCM (FCEM will, in turn, waive the sub-investment advisory
fee it receives from FCM to the same extent). These waivers do not affect the
amount of advisory fees paid by the Fund to MFS.
In addition, the strategic alliance described in the Fund's prospectus
under "Management of the Fund," pursuant to which MFS and FCM agreed to
cooperate in distributing, advising and managing investment products throughout
the world and to share certain expenses and revenues relating to their
cooperative activities, will terminate on September 8, 1997.
The date of this Supplement is September 5, 1997.
