That's why, if we're talking about liability, engineers design buildings to withstand a certain earthquake load, not the unimaginable earthquake that might occur sometime in the future. They have to pick an actual earthquake level that they design for. There's no point in designing for an earthquake that's so enormous that might have happened once or might possibly happen in the future. You have to design for the risk that you can reasonably foresee. And so once a decommissioning activity is complete, then at that point the directors in the company should be released from any future obligations.
