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 $27.5 billion.  The retirement systems
derive revenue from employer and employee contributions, court
fees, and investment income.
