Restructuring

Aon Hewitt Restructuring Plan

On October 14, 2010, Aon announced a global restructuring plan (“Aon Hewitt Plan”) in connection with the acquisition of Hewitt Associates, Inc. ("Hewitt"). The Aon Hewitt Plan is intended to streamline operations across the combined Aon Hewitt organization and includes approximately 2,200 job eliminations. The Company expects these restructuring activities and related expenses to affect operations into 2013. The Aon Hewitt Plan is expected to result in cumulative costs of approximately $325 million through the end of the plan, consisting of approximately $213 million in employee termination costs and approximately $112 million in real estate rationalization costs across the Company.

From the inception of the Aon Hewitt Plan through March 31, 2013, approximately 2,180 jobs have been eliminated and total expenses of $281 million have been incurred. The Company recorded $26 million and $12 million of restructuring and related charges in the three months ended March 31, 2013 and 2012, respectively. Charges related to the restructuring are included in Compensation and benefits and Other general expenses in the accompanying Condensed Consolidated Statements of Income.
