In fact, you wouldn't want levies in perpetuity, I think for the reason you gave earlier, Minister, which is that, first of all, you may not require them. The ship-source oil pollution fund I think is a perfect example of that, where there was a target initially for it and the levies ultimately stopped, but the fund continued to grow based on interest on the fund, to a significant level. This would function in very much the same respect, if I understand that clearly.
