The U.S. Trustee plays a major role in monitoring Chapter 11 cases by overseeing the debtor's operations and financial reporting. The U.S. Trustee conducts creditor meetings, ensures compliance with reporting requirements, and can seek to convert a case or have a trustee appointed for noncompliance. A trustee can be appointed if the debtor is dishonest or mismanaging the business, or a party requests it. The trustee then takes over management of the business from the debtor in possession and must file a reorganization plan.
