2006 Comprehensive Annual Financial Report 2006 Popular Annual Financial Report

June 22, 2007

Enclosed is a copy of the 2006 Comprehensive Annual Financial Report of the Illinois Municipal Retirement Fund. In addition to the financial statements and statistical data, the report includes a summary of benefits and the following commentaries from professional consultants engaged by IMRF:

We have not included a detailed list of investments in the 2006 financial report due to its length. The Addendum to the 2006 Comprehensive Annual Financial Report, which lists our investments, is available on IMRF’s website, www.imrf.org.

Also enclosed is a copy of IMRF’s 2006 Popular Annual Financial Report. A popular annual financial report is designed to meet the needs of readers who may not be interested in using traditional financial reports. Its goal is to make financial information more readily accessible to a broader audience.

Both the comprehensive and popular annual financial reports are available on IMRF’s website, www.imrf.org.

IMRF printed a small supply of both our 2006 Comprehensive Annual Financial Report and our 2006 Popular Annual Financial Report. Members and employers can request copies by calling 1-800-ASK-IMRF (1-800-275-4673) Monday through Friday, 7:30 a.m. to 5:30 p.m. We hope you will find these reports informative and useful.
