Key members of the supervisory board tasked with nominating a successor to Josef Ackermann, have suggested a dual CEO model, with 62-year-old Germany chief Juergen Fitschen complementing 48-year-old Jain, people familiar with the matter told Reuters.

Also under discussion is a plan to elevate Ackermann to the supervisory board, a move that will require special shareholder approval, people familiar with the matter said.

A formal decision could come as soon as Tuesday, when the supervisory board gathers for a regular meeting.

Deutsche Bank will post second quarter earnings that day, with analysts forecasting a pretax profit of 1.97 billion euros ($2.8 billion).

A supervisory board member at Deutsche Bank, who declined to be named, said there had been “informal bilateral discussions about which models could work” and that although everything is theoretically open for debate “the discussions are not starting at zero.”

He said that one of these models was Jain-Fitschen.

He declined to be drawn further but said “let’s wait and see.”

Fitschen’s contact book in political and corporate Germany is seen as an asset to complement Jain’s ability to deliver bumper earnings.

Deutsche Bank has operated with co-CEO arrangements in the past. Former CEO Alfred Herrhausen shared power with F. Wilhelm Christians before becoming sole chief executive of Deutsche Bank in May 1988.

Ackermann himself became CEO designate in September 2000 and waited until 2002 to succeed Rolf Breuer.

Breuer then went on to join Deutsche Bank’s supervisory board.
