Companies must hold an annual general meeting every year, with no more than 15 months between meetings. Extraordinary general meetings can be called to discuss urgent matters. Board meetings can be called by the secretary, director, or on the chairman's direction. Meetings must be chaired and have quorum to be valid. Notice must be sent in advance of meetings, and include time, place, agenda, and signature. Resolutions are passed by ordinary majority or 75% majority for special resolutions. Minutes record the discussions and decisions.
