POSTPETITION CREDIT

post-petition credit: The debtor in possession is allowed to incur unsecured debt in the ordinary course of business without prior court approval. Such debt will be considered a post-petition claim, also referred to as an administrative expense claim. To have the new credit secured or be granted a superpriority, the extension of credit must be approved by the court.
