Thank you, Mr. Chair.
I just want to clarify something on Mr. Julian's first question that sort of equated indirect expropriation with a loss of profit. Frankly, there's not really a basis for that equation. Loss of profit does not amount to indirect expropriation. There is an annex in the agreement that does elaborate on what indirect expropriation is, and that annex is there precisely to ensure that tribunals considering the issue of indirect expropriation look at the full range of circumstances that would constitute indirect expropriation under international law.
I would also like to point out that there is a paragraph in that annex--this is building on what Mr. MacKay just said--that says the following: “...non-discriminatory measures of a Party that are designed and applied to protect legitimate public welfare objectives, such as health, safety and the environment, do not constitute indirect expropriation.”
Also, perhaps you would indulge me and repeat the question you had about social security. I'd like to make sure we have it right when we provide a response to the committee.
