According to a new securities filing, Peabody Energy Corp. must file its plan of reorganization by Dec. 21.

The filing noted the U.S. Bankruptcy Court for the Eastern District of Missouri approved a stipulation to its debtor in possession credit agreement setting the date. The company will be required to file a related disclosure statement on the same date.

Peabody will be the latest of the large coal producers to emerge from bankruptcy. Arch Coal Inc. emerged largely intact , while Alpha Natural Resources Inc. spun out some of its most productive assets into Contura Energy Inc. in its reorganization.
