The restrictive covenant measures, as was previously mentioned, are directed at a couple of Federal Court of Appeal cases. We would view them as integrity measures.
The question that comes up is that when the restrictive covenant was given, the taxpayer, based on the cases, would take the position that the value of the covenant was not taxable. So the portion of a share sale, for example, that was related to the value of the covenant would become non-taxable.
That could have significant revenue implications, because it could arise on any sale of any business asset. As you can imagine, across the economy there would be a lot of sales in a given year. But in terms of the particular amounts for the particular sales, we'd not be able to come up with a firm figure on that, because that depends upon the Canada Revenue Agency finding the particular transactions under audit. The Canada Revenue Agency, of course, in the particular two cases that came up on appeal, found the particular transactions, reassessed the particular transactions, and the courts indicated that they thought the values were not taxable.
So these measures come back to that situation, and we say, look, that's not an appropriate tax policy result to have the particular value not subject to tax. The measures are meant to impose the tax. The risk to Treasury would be significant, but what's the particular revenue saving on it? It would be next to impossible to determine that.
