Some Eastman Kodak Co. shareholders who want compensation for losing their stock are heading to federal bankruptcy court this week, fighting a company objection to their claims, the Rochester Democrat & Chronicle reported today. Bankruptcy Judge Allan Gropper is scheduled to hear arguments today from various shareholders who have filed a claim against Kodak and now are objecting to the company's efforts to get those claims declared null and void. Throughout its bankruptcy and since exiting chapter 11 in September, Kodak has regularly filed objections in U.S. Bankruptcy Court, essentially saying that it doesn't owe anything to a particular party seeking money. The deadline for the last of those claims was Oct. 18. In November and December, Kodak filed a series of objections to claims with lists of hundreds of former shareholders who had filed claims asking to be compensated for their lost stock. Some of those shareholders are objecting to Kodak's objections.
