Thank you very much.
Mr. Brock, I'm curious to know, with respect to the issues you've raised here today.... We heard from officials on this previously. What they were saying was that the current state of affairs they are trying to correct—we can argue the merits of that and obviously we will; you have to some extent already—is this: Because it's hard to identify the customer, given the makeup of mining pools and the anonymity that exists with respect to some of those pools and the way they're constructed, it's impossible to assess the GST. There's no way for government to raise revenue on the GST. I think their claim is that the input tax credits are designed to offset tax that would be paid. Here, structurally, we have a situation in which tax cannot be paid, so it doesn't make sense to extend the input tax credit. That's what I understood from officials.
Is that your understanding, as well, or do you think there's something else about it that the committee ought to know?
