Sir, the costing that we go through is with the Department of Finance. This also goes to your previous question. We rely on the actuaries. The actuaries in the office of the chief actuary do the costings for us based upon the best information they have at the time and the projections across the board. In addition, as the Minister indicated, whenever this comes into legislation and is approved, it becomes a statutory obligation. Basically it depends upon the uptake from veterans, whether they be drawing on the education benefit or indeed for injuries.
That's why in being able to come back on a cyclical basis through the supplementary estimates, using the quasi-statutory approach that we have with Treasury Board, we're able to revisit and get adjustments as required throughout the financial year.
