Willis to Keep Name on Chicago Tower

Insurance broker Willis Group Holdings Plc plans to keep its name on the Chicago tower that is being sold to Blackstone Group LP.

The broker “is involved in a long-term contract for its naming rights for Willis Tower,” Colleen McCarthy, a spokeswoman for the London-based company said on March 17 in an e- mail. “The building’s naming rights are unconnected to the transaction announced yesterday.”

The 1,450-foot (442-meter) building, formerly known as the Sears Tower, is the second-tallest in the U.S., and was the world’s highest from its completion in the early 1970s until 1998, according to the Council on Tall Buildings and Urban Habitat.
