On December 17 ZZZZ Best Co., Inc. (the debtor), borrowed $7 million from Union Bank (the bank). On July 8 of the following year the debtor filed a voluntary petition for bankruptcy under Chapter 7. During the preceding ninety days, the debtor had made interest payments of $100,000 to the bank on the loan. The trustee of the debtor’s estate filed a complaint against the bank to recover those payments as a voidable preference. The bank asserts that the payments were not voidable because they came within the ordinary course of business exception. The trustee maintains that the exception applies only to shortterm, not long-term, debt. Who is correct? Explain.
