Thank you, Ambassador.
I wanted to follow up on something Mr. Fonseca was asking about in his questions, and I only have about a minute left. He spoke to the fact that Canada has imposed a range of sanctions on a number of individuals who have been involved in the invasion of eastern Ukraine and the annexation of Crimea.
You spoke to the fact that sanctions are necessary. You mentioned Magnitsky. You mentioned SWIFT. You talked about Russia's sovereign debt. For the members of the committee who may not be familiar with it, could you talk about what SWIFT is and what you mean when you refer to that?
