Okay.
My final question will be to spell out the overall deposits or funds in trust for the government that we talked a bit about this morning, and the issue of how much is currently set aside for nuclear liability. How much is currently set aside for mining, and how does the government evaluate whether or not that's adequate?
Finally, for oil and gas, on the issue of what is in trust currently to deal with what could be multi-billion dollar cleanup costs, how much have agencies in trust currently to deal with that?
