Business Outlook We believe that we are in a cyclical recovery in commercial real estate with annual growth expected to be similar to our long-term business model This model (on a normalized basis) is: Revenue growth of 7-9% EBITDA growth of 12-14% EPS growth of high-teens to 20% Outsourcing is likely to grow at one of the faster rates among our businesses, in the low double digits Investment sales will likely be paced by broader economic recovery driven by core asset demand in major markets with increasing contributions from secondary markets Leasing growth rates will likely continue to be modest until we see sustained job growth and rental rate increases Investment management will benefit from a full year of contribution from ING REIM We expect to once again deliver the industry’s highest normalized EBITDA margin in 2012, in large part due to our expense discipline All these factors support our 2012 normalized EPS guidance range of $1.20 to $1.25 per diluted share
