Section 547(c)(2) of the Bankruptcy Code excepts from the trustee’s power to avoid preferential transfers any transaction in which the debtor transfers property to a creditor in the “ordinary course of business.” Exactly what constitutes “ordinary course of business,” however, is not a settled question of law. In Jubber v. SMC Electrical Products (In re C.W. Mining Co.), 798 F.3d 983 (10th Cir. 2015), the U.S. Court of Appeals for the Tenth Circuit considered whether a first-time transaction between a debtor and a creditor can satisfy the ordinary course exception.
