(NYSE: RF) and Union Planters Corp. (NYSE: UPC) have organized the top management structure of the new financial powerhouse created by the merger between the two, assigning geographical responsibilities to regional bank presidents and naming senior managers to other positions. "Deciding who will lead one of the top 15 bank holding companies in the United States was not a process we entered into lightly," said Regions Chairman and CEO Carl E. Jones Jr. "We balanced our associates' understandable desire to know something as soon as possible with a careful and deliberate approach to positioning ourselves for future stability and growth. "Our decisions were made both easier and more difficult by the fact that our two companies share such a strong talent pool," Jones said, referring to current Union Planters CEO Jackson W. Moore, who is both president and CEO-designate of the new company. Moore is also slated to become chairman of the new company upon Jones' planned retirement from that role in June 2006. "We congratulate our new team, and would like to invite all associates of both companies and their peers in the industry to join us in congratulating and supporting them," Jones said. Moore will oversee the consolidated banking operations and major banking product lines, and will have the combined company's six regional bank presidents reporting to him: John I. "Jack" Fleischauer, president-Western Region (Arkansas [excluding the greater West Memphis market area], Texas and Louisiana); Adolfo Henriques, president-Southern Region (Central and Southeastern Florida, international banking and emerging markets); Peter D. Miller, president-Eastern Region (East Tennessee, Georgia, North Carolina and South Carolina); Steven Schenck, president-Mid-West Region (Western Kentucky, Missouri, Indiana, Illinois, Iowa); Samuel E. Upchurch Jr., president-South Central Region (Alabama and the Florida Panhandle); and John White Jr., president-Mid- South Region (Middle and West Tennessee [including the greater Memphis market area] and Mississippi). Also reporting to Moore will be Doyle R. Rippee, William E. Askew and Lynn Harton. Rippee will head the company's corporate banking efforts and Askew its retail banking area. Harton will serve as the company's chief credit officer. Other key positions determined were John Daniel, head of human resources; David C. Gordon, head of operations; John Dick, information officer; J.R. Eldridge, head of risk management; Alan Deer, general counsel; Dale Calvin, head of management consulting; and Paul Crawford, head of Interstate Billing. Morgan Keegan will continue to report to its CEO, G. Douglas Edwards, and Allen B. Morgan Jr. remains chairman of Morgan Keegan and vice chairman of Regions. As stated in a previous release, Robert A. Goethe will head the new company's mortgage banking line of business; reporting to him will be E.
