This goes back to how we originally set Annual General Meetings, they were held in the first or middle of December. It only changed because the then Board of Directors got very sloppy when planning for our 'Turnover' election and missed the time frame for announcing the AGM for that year, by the time they noticed they were past the notification date for an early/mid December meeting and the meeting had to go into January, then the next one (the coming meeting) was also set for January.
Now we are going back to how it was done previously and probably all our coming AGM's will be in early or mid December with a BOD meeting following it.
