It depends, Chair, upon the nature of the items. If you have a new program in a budget, because of budget secrecy and other things, you may not see work started on a new program design in earnest until the budget is actually tabled. We do have examples of cases where it's two and three years after a budget before money is actually ready to be spent.
So that is a consideration. It's not the norm, but two to three years is not uncommon.
