Yes. On the gas rig side, there's a number of gas rigs that we had drilling with the exception of the Haynesville, where we have four rigs running that were earning acreage or preserving acreage there. In most other areas of North America, for gas drilling, we've reduced our gas drilling to the number of rigs, where we have term contracts. So essentially we've laid down all our rigs that aren't contracted through the year. So we made a decision that we are not going to try and buy out of contracts just because you pay the contract money and you get nothing in return or at least if you drill in you get something in return. So that's one of the guiding factors there. As to when we would specifically shut in gas, we have curtailed shut in gas the past several years, typically in September, and we have kind of a threshold well head price that in our minds and I won't give it, but basically, we are not too anxious to sell gas below that price. So the overall strategy of the company this year is we are not going to cramp gas into markets that are already full, if storage gets full before November, we'll probably react to it by curtailing some gas, but we'll just have to see how that plays out. But what we are really doing with the company is we are switching the company toward crude oil and NGL production because we think that's going to be a more consistent value basis on a go-forward basis. There is a chart that we released on the IR chart last night on our Web site that kind of shows the ratio we expect to get to in North America for liquids versus crude and the bottom line of that chart is it was a pretty low level two years, three years ago we expect by 2013, just to give you an example, in 2006, our North American production mix was 24% liquid, 76% gas. And currently it's about 35% liquids, 65% gas for this year, and we expect that ratio by 2013 to go somewhere liquids would be 45% to 50% of our total North American production mix. That's a 10 to 1 BTU equivalent ratio.
David Tameron – Wachovia: I know you won't give me a price but can you talk regionally and then I'll hang up, let somebody else jump up. But regionally if you look at how prices today and service cost and you expect the rate of returns, what would be one, two, three, first to be shut in, second and third if you address that point?
