2004 Restatement Liabilities As part of the restatement we presented in our 2004 Annual Report on Form 10-K (the “2004 Restatement”), we recognized liabilities related to vendor discounts and credits where we had a contractual or legal obligation to rebate such amounts to our clients or vendors. Reductions to these liabilities are achieved through settlements with clients and vendors, but also may occur if the applicable statute of limitations in a jurisdiction has lapsed. As of March 31, 2012 and December 31, 2011, we had vendor discounts and credit liabilities of $52.0 and $55.5, respectively, related to the 2004 Restatement. Other Expense, net Results of operations for the three months ended March 31, 2012 and 2011 include certain items which are not directly associated with our revenue-producing operations.

Sales of Businesses and Investments – During each of the three months ended March 31, 2012 and 2011, we recognized a loss relating to the sale of a business in the domestic market within our Integrated Agency Networks ("IAN") segment. Vendor Discounts and Credit Adjustments – We are in the process of settling our liabilities related to vendor discounts and credits established as part of the 2004 Restatement. These adjustments reflect the reversal of certain of these liabilities as a result of settlements with clients or vendors or where the statute of limitations has lapsed. Share Repurchase Program In February 2012, our Board of Directors (the “Board”) authorized a new share repurchase program to repurchase from time to time up to $300.0, excluding fees, of our common stock (the "2012 share repurchase program"). In 2011, the Board authorized a share repurchase program to repurchase from time to time up to $450.0, excluding fees, of our common stock (the "2011 share repurchase program"). We may effect such repurchases through open market purchases, trading plans established in accordance with SEC rules, derivative transactions or other means. The following table presents our share repurchase activity under our share repurchase programs.
