I'm going to ask Carolyn to address the revision of potential and what that means.
I would just say, in general terms “potential” is a very uncertain concept, so it's not a brick wall somewhere out there. It can be affected by many things that we've talked about in committee today, a lot of things that can mean more potential as the economy reaches its full stride, and that postpones that point where we're going to run out of extra resources, such as 120,000 youth who have withdrawn from the workforce. That's not early retirement. That's a discouraging effect. Bringing them back in will make all the difference.
Carolyn, why don't you walk through a couple of the numbers?
