"Our raw sugar costs in the fourth fiscal quarter should see little relief, while sales prices thus far in the fourth quarter have only improved modestly," said John Sheptor, president and CEO of Imperial Sugar.

"The company is reviewing potential operating and capital improvements, particularly in the utilities, raw sugar melt and water management areas of the refinery, to begin addressing mechanical reliability in these operations. These areas, which were not part of the reconstruction efforts following the accident, have proved to be impediments to sustaining efficient operations at the production rates achieved prior to the accident," said Sheptor.
