That holding company is Porsche SE, the investment arm of the Piëch and Porsche families (Ferdinand Porsche's descendants) which holds over 50 percent of VW's shares. In 2008, Porsche SE acquired majority interest in the Volkswagen Group which in turn acquired Porsche the automaker – and placed VW's Winterkorn at the head of the executive board of the holding company. Though Winterkorn has resigned from his position as chairman of VW's management board, he has apparently yet to step down from running Porsche SE.
That's not the only job that Winterkorn still retains in VW's senior management. He also continues to serve as chairman of Audi, as well as truck manufacturer Scania, and the new Truck & Bus GmbH into which Scania has been grouped together with Man. It remains unclear if or when Winterkorn might resign from those positions as well, or how his tenure in those posts might affect the company's effort to start over in the aftermath of the scandal in which it is currently embroiled.
Also unclear, Reuters reports, is how much, exactly, Winterkorn will receive in compensation after having stepped down from his chair at the head of the VW executive board. His pension is reported at over $30 million, but he could be awarded a large severance package as well amounting to as much as two years' worth of his annual compensation, which amounted to around $18 million last year. Whether he receives the severance pay or not is expected to depend on whether his resignation is considered by the supervisory board to have been the result of his own missteps or independent of the situation that resulted in his resignation. One way or another, he's not likely to go poor anytime soon.
