Coffeyville refinery shut to Sept

Independent U.S. refiner Coffeyville Resources’ debt ratings were cut on Monday as an industry source said the company’s flooded Kansas refinery was unlikely to restart until early September.

Moody’s Investors Service pushed Coffeyville’s corporate family rating deeper into speculative territory, cutting it from B2 to B3 amid uncertainty over the losses Coffeyville faces from the shutdown of the refinery and an associated oil spill.
