We have a study on file that's listed in our submission. What happens— and I'll pick a smaller one. Bob's picked some big ones—is a $4-billion investment that's under active consideration will take about five years to construct.
In the meantime, all that capital, all the investment, is inactive, but if the companies could recover some of that in rapid writeoff against other expenses, it would allow them to borrow in that particular case, per billion dollars, about $220 million less right up front. That cash flow allows you to make that much more investment. It's just a good way to incent the industry, yet get all the taxes back within the next year.
