"Notice Pursuant to Rule 304 of S-K"
Pursuant to the Regulation, Calvert Social Investment Fund hereby notifies the
Securities and Exchange Commission of the following:
Change in Independent Auditor
In September 2000, PricewaterhouseCoopers LLP (PricewaterhouseCoopers) resigned
in the normal course of business as independent auditor for the Calvert Group
Funds. Arthur Andersen LLP (Arthur Andersen) was selected as the Fund's
independent auditor. The Funds' selection of Arthur Andersen as its independent
auditor was recommended by the Fund's audit committee and was approved by the
Fund's Board of Trustees.
The reports on the financial statements audited by PricewaterhouseCoopers for
the years ended September 30, 1999 and prior for the Funds did not contain an
adverse opinion or a disclaimer of opinion, and were not qualified or modified
as to uncertainty, audit scope or accounting principles. There were no
disagreements between the Funds and PricewaterhouseCoopers on any matter of
accounting principles or practices, financial statement disclosure, or auditing
scope or procedures, which disagreements, if not resolved to the satisfaction of
PricewaterhouseCoopers would have caused it to make reference to the subject
matter of the disagreements in connection with its reports on the financial
statements of such years.
