Section 16 is in the nature of good housekeeping and simply provides that any excess revenue will be carried forward by the supervisory authority from one year to the next. Likewise, sections 17, 18, 19 and 20 have all to do with housekeeping matters and deal with the staff that the authority will have, the disclosure requirements of both directors and staff and the ability of the authority to establish appropriate superannuation arrangements for the chief executive officer and the staff of the supervisory authority.
