In 2012, the Company implemented restructuring actions which resulted in costs totaling $78 million. Approximately $58 million of the restructuring charges are related to Mercer, approximately $51 million of which was incurred in the fourth quarter of 2012 related to senior management's recent operations review, including costs of approximately $16 million related to the disposal of Mercer's Canadian outsourcing business. The remaining restructuring costs consist primarily of severance and benefits, costs for future rent and other real estate costs. These costs were incurred as follows: Risk and Insurance Services—$8 million (all acquisition related); Consulting—$58 million (acquisition related—$1 million); and Corporate—$12 million.
