P24, here is a little info about the Advanced Notice Policy:

Shareholders or proxyholders may, at a meeting called for the purpose of electing directors, nominate from the floor of the meeting one or more persons to serve as a director. Since no prior notice of such nomination need be given to the issuer or its shareholders, this type of nomination is often referred to as an ‘ambush.'

Advance notice provisions have been designed to prevent shareholders from nominating directors through a proxy fight or an ambush, without in each case providing an issuer with adequate time to consider and respond in an informed way to such proposed nominations.
