Notes written by strategy chief Ruediger Grube three months before Daimler-Benz combined with Chrysler Corporation describe a takeover rather than a merger, according to documents released last month in a federal court in Delaware, Bloomberg News said. The Grube notes conflict with the public statements of executives in later months and may support assertions in a lawsuit by billionaire investor Kirk Kerkorian and other shareholders seeking as much as $US15 billion from DaimlerChrysler AG, the news agency said.
