I spoke to this a bit earlier. I can only speak to the closed-loop network that we have, but we really have a layered security strategy in fraud monitoring and a robust security and risk strategy. It's multiple different controls and security standards that we have on our network.
The Mastercard and Visa networks are largely based out of the U.S., and then operate on a global basis, so they have a different set of standards that they're going to meet, a differently layered security structure that they're required to meet and a different risk appetite. I can't speak as much to theirs. I can only speak to the safety and soundness that ours provides to Canadians.
