GREEN CENTURY FUNDS
SUPPLEMENT DATED JULY 7, 1999
TO PROSPECTUS DATED OCTOBER 28, 1998
At a special meeting held on June 18, 1999, the shareholders of the Green
Century Balanced Fund (the "Fund") approved a new subadvisory agreement (the
"new subadvisory agreement") effective April 1, 1999 with Green Century Capital
Management, Inc. (the "Adviser"), Winslow Management Company ("Winslow"), a
separate operating division of Adams, Harkness & Hill, Inc. ("AHH"), and the
Green Century Funds on behalf of the Fund. Before April 1, 1999, Winslow was a
separate operating division of Eaton Vance Management ("Eaton Vance"). Winslow
has been the subadviser to the Fund since July 1, 1995. By mutual agreement of
Eaton Vance, Winslow and AHH, ownership of Winslow was transferred from Eaton
Vance to AHH effective April 1, 1999; consequently, the old subadvisory
agreement dated July 1, 1995 was terminated effective March 31, 1999.
Under the new subadvisory agreement, Jackson W. Robinson, the President of
Winslow, (the "portfolio manager") will continue to manage the Fund's portfolio
in accordance with its existing investment objective, policies, restrictions and
criteria for corporate environmental responsibility. The subadvisory fee rate
payable by the Adviser to Winslow will be calculated at the same rate, and the
new subadvisory agreement is in substantially the same form as the old
subadvisory agreement. The Adviser, and not the Fund, will pay the subadvisory
fees to Winslow. The new subadvisory agreement will continue in effect for one
year from April 1, 1999.
The Green Century Balanced Fund may invest any portion of its assets in the
securities of small and micro-capitalization companies. Small companies are
defined here as companies with market capitalizations between $250 million and
$1 billion; micro-capitalization companies have capitalizations of less than
$250 million. The Fund's portfolio manager believes that the environmentally
distinguished companies in which the Fund seeks to invest tend to have smaller
market capitalizations and that investments in such companies may offer greater
opportunities for growth than larger, more established companies. Investing in
the securities of smaller companies however involves greater risks than
investing in the securities of larger companies. Small companies may lack the
management experience, financial resources and product diversification of large
companies. In addition, the frequency and volume of trading in their securities
may be substantially less than that of larger companies. Therefore, the
securities of small companies may be subject to wider and more erratic price
fluctuations.
