Explanatory statement requirement: notice for special business must disclose directors' interests and state where documents can be inspected. Section 173 requires that notices for meetings containing special business be accompanied by an explanatory statement setting out all material facts about each item, including the nature of any concern or interest of every director and the manager. If the special business affects another company, the statement must state the extent of directors' or managers' shareholding interest in that other company when it meets the statutory threshold. If approval of any document is sought, the statement must specify where and when the document may be inspected.
