Let me just add one point.
On that as well, they need to recognize that it's not just written off in one year. The accelerated capital cost allowance can only be written off to the extent of revenue from the mine, and it has to wait until you actually have production coming forward or be subject to the available-for-use rule. So there are restrictions on it. As in the example I showed, it actually doesn't all get written off in year six when you start up. It's limited, and it gets stretched out over a longer period. But it is not over the entire life of the mine, that is correct.
