In a deal worth almost $5 billion, consulting and insurance company Aon Corporation is buying HR outsourcing firm Hewitt Associates. The newly-formed Aon Hewitt division will function much like Hewitt Associates did before the purchase. The companies estimate that this merger will eventually save the companies $355 million each year.

The Aon Hewitt purchase

Announced this morning and expected to close in November, the Aon purchase of Hewitt Associates will cost $4.9 billion. Aon Corporation is paying about $50 per share for Hewitt Associates, about 41 percent more than current value. Current Hewitt stockholders will get $25.61 in cash and .63 pieces of stock in Aon Corporation. Aon Hewitt will keep the same CEO and business model as Hewitt Associates while combining back-office operations with Aon. After news of this purchase, Hewitt Associates stock jumped, while Aon stock fell on Monday morning. This new company will be based in Illinois. No word yet on how many employees of Aon or Hewitt may lose their jobs during this combination of business operations.
