Exhibit to Accompany
Item 77J
Form N-SAR
Green Century Equity Fund
(the "Fund")
According to the provisions of Statement of Position 93 - 2 (SOP 93 - 2)
"Determination, Disclosure
and Financial Statement
Presentation of Income, Capital Gain and Return of Capital Distributions by
Investment Companies,"
the Fund is required to
report the accumulated net investment income (loss) and accumulated net
capital gain (loss) accounts to approximate amounts
available for future distributions on a tax basis (or to offset future
realized capital gains). As a result, the Fund has reclassified
net realized gain of $31,217 to increase undistributed net investment
income by $31,217 for the six months ended January 31,
1999.
This reclassification has no impact on the net asset value of the Fund
and is designed to present the Fund's capital account on a
tax basis.
