The forecast for the disability pension grant decreased due to fewer eligible war service veterans than originally forecast. This is an example. VAC reallocates this money to programs that require additional funding before seeking new funding from the fiscal framework. The transfer payment table lists all the grants that require an increase in authority regardless of whether new funding was required, and this is the reason that the total of these grants and contributions exceeds the amount of new funding being requested.
