Okay, with that, I think we are going to wrap it up. But just before you do, I want to add one more point on the gold question, just to give some illustration of when we might do something in gold, and that has to do with mine life. One of the things in gold, geologically, is it tends to have much sort of mine life than what you will see in our portfolio. Our portfolio has several operations with 50 years plus, and we know that, if you have 50 years, that we are going to experience not one, but several cycles of two or three good years, when you get all your capital back. And if you back calculate your IRR again, the 50 years that you've had five, six or seven times, when you're going to come back [ph], you get a very good return. One dilemma with gold is that most of them are 10-12 years or even shorter, and if you get a bad run of three or four years, you don't get a chance to earn that kind of return. So that makes a big difference to us. We have a ratio that I have talked about before, but maybe not enough, that we use called mine life to payback. So for example if you have a large capital investment or acquisition cost that you normally think of a payback in the seven to eight year range. If we want a minimum mine life to payback of three, which is our target, then you want to have at least 25 year mine life. In several of our operations in QB and Fort Hills that we are building. These things have a six or seven times mine life to payback. So we have a lot of comfort that we are going to get a good return. Its very hard to find that in gold. But if we do, we'd be very interested. So I hope that adds a little bit color on how we think about that. And with that, I want to thank you very much for your questions. As Greg said, if you have further questions, please don't hesitate to call him directly, and with that, we look forward to talking to you next quarter. Bye for now.
