If the savings created by centralizing data and services were $45 million, that would mean that your study would have cost 5% of future savings. I think that's huge.
As for potential future savings, you estimated that the cost reductions would be between 6% and 36% of the amounts currently committed, or $45 million to $293 million, which is a fairly large margin. Why be so cautious? Why such a margin? Is it because it's difficult for you to really see how much we'll save?
