Aside from all this, if you were running a business, and you had a key piece of equipment that needed to be replaced, and you are going to look at projecting what it would cost to replace it and so on, and what it would cost to run it, would you be interested in the delta—over operating your current piece of equipment versus the replacement piece of equipment? Because you already have the people there who are operating that old equipment. They can operate the new one, and so on. Would it not make sense to be more interested in the delta? What's already there for the old one is going to be there for the new one. Nothing changes.
