I think the simple answer is the latter part of your question, Mr. Allen. It would be a tremendous undertaking for us to quantify that, even for our own industry. Our companies are individual corporate entities with competitive interests. They don't share that information even with us. Then you have the other major industries that you would need to look at as well.
Mr. Hemmes, who testified earlier, is one of the people who would have the skill set and the capacity to help guide that study.
