Thank you, Mr. Chairman. Yes, I appreciate that in some of the really longstanding deals before the whole consciousness of environmentalism and liability was really at the fore, that our government probably did not include the kind of contingent liability things that we should have in the transfer. I accept that. The main purpose of my question here is to make sure that on each and every one of these properties that we're dealing with and potentially taking over, that this is one of the criteria that we're looking at to explore whether there was a previous owner/operator and to what extent, if any, can they also be held responsible for the cost of the cleanup. I just want to make sure that that is part of the process that we use when we book these kinds of liabilities. That's all, Mr. Chairman.
