In 2006, a German government investigation uncovered slush funds in secret bank accounts maintained by Siemens in order to win contracts. Investigators found no evidence of wrongdoing by Kleinfeld and no charges were brought against him. In 2009, Kleinfeld, along with other former top Siemens executives, agreed to pay Siemens a sum to settle a related civil matter. In June 2007, Kleinfeld left Siemens, citing uncertainty about his future with the company after divisions among Siemens board members concerning the extension of his contract became public.
