The 6th Circuit Court of Appeals, in the case of In Re Finn, upheld a finding that an otherwise preferential transfer is not avoidable if it was payment of a debt incurred in the ordinary course of the debtor's business or financial affairs. The Court held that even the incurring of long-term consumer debt satisfies the Bankruptcy Code §547 (c) (2) (A) exception from avoidance rules, as long as it is a normal financial relationship. The Court held that a transfer can be in the ordinary course of financial affairs even if it is the first of such transactions undertaken by the debtor.
It should be noted however, that a majority of courts hold that interest payments on long term debts are not covered by the ordinary course of business exception. See Wolas v. Union Bank and In Re ZZZZ Best Co., Inc.
