I will just speak to the measure. Generally, when you have an exemption system and you recognize foreign earnings and you put them in an exempt surplus bucket such that they can be repatriated to the home country—in our case, Canada—without any further tax, you have to have protective measures in the system to avoid transactions that manufacture or fabricate exempt surplus in circumstances where there has really been no underlying surplus.
One of the mechanisms prior to hybrid surplus that may have been available to Canadian-based companies to do that would be when a foreign affiliate that is a holding company—so the holding company is owned by the Canadian parent and the holding company owns shares of other foreign affiliates below it—could sell the shares of the lower tier foreign affiliate to another company in the group, so there's no economic realization of gain outside of the group. That kind of transaction would create...to the extent there was a capital gain, mirroring the fact that we only tax half of the capital gains domestically. We put half of the capital gain in exempt surplus and half of the capital gain in taxable surplus. But provided the shares of the underlying affiliate are involved in an act of business only, we don't tax that gain currently. We will only tax that pool upon repatriation.
There's a couple of things at issue here. It's not really the case that there's been an amount of surplus created equal to the amount of the capital gain. There has, as a matter of form because there's been a real internal transfer, but there hasn't been a real realization by that corporate group, outside of the group, for cash proceeds. That's just one example of the potential to manufacture surplus, so that half of that gain, then—if there was cash available elsewhere in the group—could now be repatriated to Canada without any further tax.
The hybrid surplus concept bolts the taxable and the tax-free portion of that gain together, and if there is no underlying foreign tax related to the capital gain—and usually there is not because that holding company is in a jurisdiction that doesn't pay tax—then effectively now repatriating any amount out of the hybrid surplus pool will result in some level of additional residual Canadian tax. But you can't take the step of just creating an exempt surplus pool to the extent of one-half of that capital gain.
