I'm not aware of any connection between us signing the tax treaty and there being a tax haven angle to it. But it was the second point that I wanted to draw out.
In addition to simply having low tax rates, one can arrive at having low or no tax through lack of concordance in two countries' tax rules. That's the tower structure illustrated in the materials that were issued yesterday. It's a structure that's exclusively between Canada and the United States and involves no other country. But the effect of it is to achieve a deduction in Canada and a deduction in the U.S.
So I'm not calling us a tax haven and I'm not calling the U.S. a tax haven, but the effect of it is perhaps even better than one can get with some low-tax jurisdictions.
