Proceedings under this subpart are commenced by the issuance of a notice by the Board. Such notice shall state the time, place, and nature of the hearing, the name and address of the presiding officer if one has been designated, and a statement of the matters of fact and law constituting the grounds for the hearing. The matters of fact and law alleged in a notice may be amended by the Board at any stage of the proceeding and such amended notice may require an answer from the party or parties served and may set a new hearing date. A copy of any notice served by the FCA on any System association, director, officer or other person participating in the conduct of the affairs of the association will also be sent to the supervisory bank.
