We do. It varies, realistically, because some of the communities we're heading into are very remote. If we were to compare the cost per kilowatt hour of a lighting upgrade in a city to putting insulation into a remote community where you have to take a barge and fly materials in, they're not equitable to compare.
I can provide some of that information later, but it's not a metric that we use to compare our internal programs that are so different in scope. We really focus on, within each community, what the major issues are and what needs to happen and the best business case for that community itself.
