It's pretty good. We don't have the data with us today, but I think one of the big things we focus on is what the homeowners say.
The homeowners are saying their bills are going down. They're more comfortable. They understand what energy efficiency is. They know that putting in a light bulb saves them energy. Then maybe six months down the road they're going to install insulation, and then maybe in another year they're going to go for a furnace. It's really a journey that we lead our participants on.
