I'm not an expert in this area. I don't believe there's any sort of generic fund—certainly not a government-held fund that people in certain types of industries would have to contribute to. What happens in the current day, if you're a company involved in mining or whatever where there is a risk of pollution, is that you're are booking contaminated site liabilities just as we are. You are actually booking the liability, as you should, for their books, for their cleanup.
So they're recording the cost. Are they putting away money to allow them to clean it up? I'm not aware of any specific fund. I don't think anyone here is.
