The ServiceMaster Co. anticipates completing the relocation of its corporate headquarters staff from Downers Grove, Ill., to Memphis, Tenn., by the end of 2007, according to the Memphis Business Journal. In March, the company announced it would be acquired by New York-based private equity firm Clayton, Dubilier & Rice Inc.

The company announced its plans to move last fall, saying that roughly 165 corporate positions would transfer. The company has since said that between one-half and one-third of the people currently in those positions won't make the move.
