An Ad Hoc bondholder committee is an unofficial committee which provides a mechanism by which creditors or equity interest holders with a common agenda can join together on an informal basis to advance their interests in the reorganization process. The committee can be formed by any group of creditors or equity holders to advance a common agenda through its legal counsel. Unlike the official creditor committee which is appointed by the United States Trustee and are expected to take positions for unsecured creditors or equity holders as a whole. The Ad hoc committee can advocate is its specific interests if it chooses.
