I hate to even take a stab at it. We certainly have our tax specialists, who aren't here today, although I can't speak for Gary.
The issue on the gross production only is that it doesn't have any weighting on the cost. From my own experience with AREVA in the last several years, it's not like our profit margins at the McClean Lake property--which is our mine and is now a shut-down mill--were significant. So if it's just based on a pure pound, it's difficult to recover your costs.
Gary, if you could....
