On November 5, The Fred Hawes Organization, Inc., a small subcontractor, opened an account with Basic Distribution Corp., a supplier of construction materials. Hawes promised to pay its bills within 30 days of purchase. Although Hawes purchased a substantial quantity of goods on credit from Basic, it made few payments on the accounts until the following March when it paid Basic over $21,000. On May 14, Hawes filed a voluntary petition under Chapter 7. Does the bankruptcy trustee have a right to recover this payment? Is it fair to Hawes’s other creditors if Basic is allowed to keep the $21,000 payment?
