I think the best estimates are that we'd save about 30% of what we're spending at that time, and at the time we did the Canadian Medical Association Journal study, that was about $7 billion of the drugs eligible for coverage. By the time Canada rolls such a program out, it will be a different number. It will be bigger than $7 billion or around $7 billion, depending on whether or not we're able to keep the spending levels constant right now under the pressures we're facing.
