Perhaps I can explain what is meant by that.
Initially with any policy item, but particularly with a new bill, a lot of details need to be sorted out. So the first cost estimates are necessarily going to be high level. They're only going to take some factors into account. As more and more pieces of the puzzle fall into place, as the bill becomes law, as the initiatives under the bill become fleshed out, as you determine how many FTEs you need, as all those details become fleshed out, the costs become more precise. So from a high level to a more detailed level is really what I was trying to explain. We don't have all the details in the beginning. You do the best you can on the costs involved and then you end up with something that is very detailed for consideration for funding and for approval in Parliament as well.
