NEW YORK, Oct. 29 2004 LAWFUEL – Class action, lawsuit, legal, law, law firm news — On October 29, 2004, Wolf Haldenstein
 Adler Freeman & Herz LLP filed a class action lawsuit in the United States
 District Court for the Northern District of Illinois, on behalf of all
 participants and beneficiaries of the 401(k) Savings Plan (the “Plan”) of Aon
 Corporation (“Aon” or the “Company”) (NYSE: AOC), between November 1, 1998 and
 the present, inclusive (the “Class Period”), against defendant Aon and certain
 officers and directors of the Company.
A copy of the Complaint is available from the Court, or can be viewed on
 the Wolf Haldenstein Adler Freeman & Herz LLP website at http://www.whafh.com.
The Complaint alleges that during the Class Period, Plan fiduciaries knew
 or should have known, that the Company was paying illegal and concealed
 “contingent commissions” pursuant to illegal “contingent commission
 agreements;” that violated applicable principles of fiduciary law, subjecting
 the Company to enormous fines and penalties totaling potentially tens — if
 not hundreds — of millions of dollars.
Plan fiduciaries knew, or should have known, that this business practice
 was improper and unsustainable and that the value of the Company’s stock, and
 thus the value of the Plan, was based on financial results dependent on these
 unsustainable business practices.
By no later than November 1, 1998, AON and the Individual Defendants knew,
 or should have known, that AON’s stock was a highly inappropriate investment
 for a long-term retirement savings plan such as the Plan because of the
 financial issues described above and other questionable business practices.
 Despite this, Defendants continued to offer AON’s stock as a Plan investment
 alternative, continued to cause AON matching contributions to be invested in
 AON stock, and failed to impute their full knowledge of the Company’s
 operations on Plan participants so that the Plan participants could make an
 informed decision concerning their Plan investments in Company stock.
If you were a participant or a beneficiary of the Plan, you may retain
 Wolf Haldenstein, or other counsel of your choice, to serve as your counsel in
 this action.
