Deutsche Bank (DBKGn.DE) is freezing 2015 cash bonuses for its executive board as it examines whether some managers could have done a better job at avoiding problems that led to expensive litigation, a person familiar with the matter said. The bonus freeze hits all members of the management board except Deutsche Bank’s new Chief Executive John Cryan, new Chief Financial Officer Marcus Schenck and new retail bank head Christian Sewing, the person said.
