Peabody Energy Corp., the largest U.S. coal producer, raised substantial doubt about its ability to remain as a going concern and said it may need to seek chapter 11 protection, after it delayed an interest payment, Reuters reported today. Peabody said that it skipped a $71.1 million interest payment on its senior notes due on Tuesday, kicking off a 30-day grace period. The company flagged bankruptcy risk under the "risk factors" section of a regulatory filing on Wednesday.
