 Eastman Kodak revealed on Wednesday that a series of internal errors allowed five former executives to sell roughly 5.1 million worth of stock options in July, the same month a highly scrutinized federal loan announcement sent the companys stock price soaring more than 2,100. The company learned of deficiencies in the controls used to protect its assets, David Bullwinkle, Kodaks chief financial officer, said in a Tuesday earnings call. The lack of proper controls allowed for the unauthorized issuance of common stock when previously forfeited stock options were exercised by the ex-executives in July, the CFO added.
