An important factor in many successful chapter 11 reorganizations is the debtor’s ability to procure necessary goods and services postpetition. Without some additional incentive, however, third parties would be unlikely — if not altogether unwilling — to do business with a debtor postpetition. To this end, the Bankruptcy Code includes a number of provisions aimed at encouraging third parties to conduct business with chapter 11 debtors. One of the Bankruptcy Code’s most powerful incentives in this regard is section 507(a)(2)’s grant of priority for the “actual, necessary costs and expenses of preserving the estate” allowed as administrative expenses under section 503(b)(1). These provisions ensure that vendors providing postpetition goods and services to the debtor will generally receive payment ahead of the debtor’s prepetition unsecured creditors.
