Thank you for the opportunity.
We haven't identified a separate number in our reports; however, the savings that are realized from our greening operations are reflected in our annual ask for the operation of our inventory. As you know, part of our requests every year reflect changes in the costs of heating, cooling, and maintenance of our buildings, so each year it shows up more as something not asked—it is a cost avoidance. But it is not specifically targeted and carved out as a saving arriving from the implementation of these initiatives.
