Pursuant to State Law (Section 91 of Act No. 380 of the Public Acts of 1965,
as amended), the State Treasurer, State of Michigan is the investment
fiduciary for the following four State sponsored retirement systems:
Public School Employees' Retirement System; State Employees' Retirement System;
Michigan State Police Retirement System; and Judges' Retirement System.
The Michigan Department of Treasury's Bureau of Investments performs the
investment function, under the direction and on behalf of the State Treasurer.
The aforementioned State Law created an Investment Advisory Committee comprised
of the Director of the Department of Commerce, the Director of the Department
of Management & Budget, or their duly authorized representatives,
and three public members appointed by the Governor with the advice and consent
of the Senate. The committee meets quarterly and reviews investments, goals,
and objectives, and may submit recommendations to the State Treasurer.
The Investment Advisory Committee may also, by a majority vote, direct the
State Treasurer to dispose of any holdings which in the committee's judgement
is not suitable for the funds involved, and may by unanimous vote direct the
State Treasurer to make specific investments.
Act No. 314 of the Public Acts of 1965, as amended, authorizes the investment
of assets of public employee retirement systems or plans created and
established by the state or any political subdivision.
The acquisition of equity securities are made for investment purposes only.
Investments in equity securities are made from the assets of the
aforementioned four retirement systems with total assets of approximately
$40.0 billion. The retirement systems derive revenue from employer and
employee contributions, court fees, and investment income.<PAGE>
