None of the biggest firms on Wall Street have split their two top jobs permanently. At Merrill Lynch, David H. Komansky will remain chairman until April when he will yield that title to E. Stanley O'Neal, who succeeded Komansky as chief executive last year, a firm spokesman said.
At the Goldman Sachs Group, Henry M. Paulson Jr., who has criticized the governance of other companies, is chairman and chief executive. A Goldman spokesman said the firm had no plans to separate the jobs because it already had an independent board.
Citigroup, JP Morgan Chase, Morgan Stanley, Lehman Brothers Holdings and Bear Stearns each have one man serving as chairman and chief executive.
