I think to be philosophical, the best regulation is the responsibility of the chief executive to protect the assets the shareholders have paid for. When you look at safety cultures, you go to a potash mine in Saskatchewan and you'll see a huge billboard on the outside of the potash mine saying how many thousand or million person hours that mine has had without a single workplace incident.
One of our member companies mottos is “Safety Today”, not “Safety Tomorrow” but “Safety Today”. They drive this safety philosophy all the way through their corporate structure and that's a responsibility to their shareholders. I think that is more effective than regulation by government in terms of a cost-effective way of improving safety.
