German children's production company EM.TV & Merchandising AG has named Rolf Rickmeyer chief financial officer. This move comes in light of deputy chairman Florian Haffa's stepping down from the position. EM.TV's stock has lost more than two-thirds of its value since an accounting error in the acquisition of the Jim Henson Co. and Formula One cut earnings for the first quarter. Previously, Rickmeyer served as CFO for Lahmeyer AG, a German utility and machinery company.
