I'm not sure what is referred to here.
We keep a running calendar of Board meetings and events that is updated and provided for information in the back of the materials sent out for every regular Board meeting. A precedent for this would not be useful as it would not be replicable from board to board.
We lso maintain a "checklist" for the Board and each committee which list all of the responsibilities to be met by the Board or relevant committee, as defined in their respective Terms of Reference, legislation and securities requirements (listed down the "Y" axis). Across the top, we list the months in which we schedule regular quarterly meetings and then make sure that each required activity is given a spot on one agenda. This enables us to ensure that nothing ever falls through the cracks. In addition, each checklist is reviewed annually or more often, if required, to ensure that it is comprehensive and that the Board's/committee's work is spaced evenly throughout the year.
Is this what is meant?
