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 $26,637 to increase undistributed
net investment income by $26,637 for the year ended July 31,
1998.
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.
To the Board of Trustees and Shareholders
The Green Century Funds
In planning and performing our audit of the financial statements of
the Green Century Balanced Fund (the "Fund") at July 31, 1998
and for the month then ended, we considered its internal control,
including procedures for safeguarding securities, in order to
determine our auditing procedures for the purpose of expressing
our opinion on the financial statements and to comply with the
requirements of Form N-SAR, not to provide assurance on internal
control.
The management of the Fund is responsible for establishing and
maintaining internal control. In fulfilling this responsibility,
estimates and judgments by management are required to assess the
expected benefit and related costs of controls. Generally, controls
that are relevant to an audit pertain to the entity's objective of
preparing financial statements for external purposes that are fairly
presented in conformity with generally accepted accounting
principles. Those controls include the safeguarding of assets
against unauthorized acquisition, use, or disposition.
Because of inherent limitations in internal control, errors or
irregularities may occur and not be detected. Also, projection of
any evaluation of internal control to future periods is subject to the
risk that it may become inadequate because of changes in
conditions or that the effectiveness of the design and operation
may deteriorate.
Our consideration of internal control would not necessarily
disclose all matters in internal control that might be material
weaknesses under standards established by the American Institute
of Certified Public Accountants. A material weakness is a
condition in which the design or operation of any specific internal
control component does not reduce to a relatively low level the
risk that errors or irregularities in amounts that would be material
in relation to the financial statements being audited may occur and
not be detected within a timely period by employees in the normal
course of performing their assigned functions. However, we noted
no matters involving internal control, including controls over
safeguarding securities, that we consider to be material weaknesses
as defined above as of July 31, 1998.
This report is intended solely for the information and use of
management and the Securities and Exchange Commission.
