The closing of this transaction is subject to specified closing conditions, including the approval of the Bankruptcy Court.

On December 18, 2017, the subsidiaries of the Company conducting its New England Wood Pellet business, which have not filed for bankruptcy protection, entered into an Asset Purchase Agreement with Lignetics of New England, Inc., a subsidiary of Lignetics, Inc., for the sale of substantially all of the assets of that business.
