Consistent with other tax treaties, and I think the general approach of countries worldwide, it's almost impossible to calculate the total costs and benefits of a tax treaty. That's because a tax treaty looks to improve trade and investment between two countries, and it's very difficult to attribute increased trade and investment specifically to one thing, such as a tax treaty. We have not done estimates with respect to Madagascar, but that's consistent with the rest of our treaty network. My general sense is that, internationally, there's no accepted or understood method to be able to price the costs and benefits of a tax treaty with any degree of certainty.
