BERLIN (AP) — German prosecutors have widened their investigation into Volkswagen’s handling of the emissions scandal to include its board chairman, Hans Dieter Poetsch, the company said Sunday.
Poetsch was VW’s chief financial officer when the company’s efforts to rig cars to cheat on U.S. diesel emissions tests became public in September 2015.
Volkswagen said in a statement that prosecutors in the German city of Braunschweig are investigating three members of the board including Poetsch. Prosecutors were already investigating former Volkswagen CEO Martin Winterkorn and VW brand chief Herbert Diess over allegations they didn’t inform investors soon enough.
VW rejects those allegations.
“Based on careful examination by internal and external legal experts, the company reaffirms its belief that the Volkswagen board of management duly fulfilled its disclosure obligation under German capital markets law,” it said in the statement Sunday.
The company said VW and Poetsch would “continue to give the inquiries by the public prosecutor’s office their full support.”
German law requires publicly traded companies to alert investors as soon as they become aware of unforeseen developments that could affect a decision to buy or sell the stock.
The company has acknowledged learning in May 2014 that an environmental group had uncovered emissions irregularities, but that top officials didn’t discuss the matter until more than a year later. The U.S. Environmental Protection Agency issued a violation notice on Sept. 18, 2015, leading Volkswagen to assess the risks as more serious and issue its investor advisory on Sept. 22, 2015.
Last month, a U.S. federal judge in San Francisco approved a $15 billion settlement under which Volkswagen will buy back or fix almost half a million cars affected by the emissions scandal in the United States.
