Itron Inc.'s chief financial officer exercised stock options that netted him $803,430 before taxes in the days leading up to the company's disappointing third-quarter earnings report, but Itron said there are no insider trading concerns. The executive, Steven Helmbrecht, used a prearranged trading plan designed to comply with a U.S. Securities & Exchange Commission rule, called 10b5-1, that addresses insider trades, the company said in response to a reporter's questions. Under the plan, Helmbrecht exercised four sets of stock options in October – the latest coming Oct. 29 as the company prepared to release earnings results to Wall Street.
