Thank you very much for the question. I'll try to be brief, being aware of the time there.
We track the number of pre-retrofit evaluations and the number of post-retrofit evaluations, which are in fact grant applications. We track the spending week by week. We track the spending forecast every week for the next 18 months, or March 31, 2011—in other words, the forecast liabilities associated with all of the participants in the programs to date. We track the emission reductions, the energy reductions, the turnaround time in dealing with the applications, and the number of calls and letters we receive about the program and many other things, but those are probably the most important. Certainly all of this information will be used in the evaluation to inform future decisions.
