First of all, the U.S. sought as much as possible to have identity in the agreements they negotiated with every country. Understandably, if they're trying to negotiate with the world, and I think they've signed as of today 30 of these agreements, they weren't much minded to be very novel. That made it very difficult, a tougher discussion, but we did push to achieve as much as we could in relation to Canada.
The two types of exemptions—the key ones I would identify so I don't take up the whole hour with this answer—are for small financial institutions, those having less than $175 million in assets. Also, another definition was those that had 98% or more of their client base as Canadian, and weren't part of a multinational group. Those institutions would be exempt from reporting. I rush to add, that's common to other agreements as well.
Something that's specific to Canada is the exclusion of a wide range of accounts, specifically registered accounts. It's not a complete list but it's nearly so: registered retirement savings plans, registered retirement income funds, pooled registered pension plans, registered pension plans generally, tax-free savings accounts, registered disability savings plans, registered education savings plans, and deferred profit-sharing plans. These are all exempt from reporting under the IGA in support of FATCA.
