Volkswagen just released a statement asserting that the company's board members were not involved in the emissions scandal and that only a small group of employees were responsible. The company's chairman, Hans Dieter Poetsch, said the investigation is ongoing and complex as there was a series of "errors" that led to the ultimate emissions snafu. The company also announced that it agreed to implement steps to improve oversight of the engine-software development to "avoid any future emissions test manipulations." They are also hoping to reach an agreement with U.S. environmental authorities in order to recall cars affected in the U.S. The company is still doing well despite the scandal and sales are up 3.5%. Chief Executive Matthias Mueller stated that the crisis has allowed the corporation to create structural change that was needed to improve the company and correct perceived errors.
