Siemens AG said Tuesday it plans to sue two former CEOs and nine other ex-executives for alleged supervisory failings in a corruption scandal that has cost the company millions in fines and damaged its reputation. Siemens' supervisory board decided to seek damages from former chief executive Heinrich von Pierer and his successor, Klaus Kleinfeld, now the chief executive of U.S.-based Alcoa Inc., and others, the industrial conglomerate said in a statement.
