I am going to have Jeff Wojahn, responsible for our USA Division, provide a little bit more insight. But we are in a lot of these plays still building acreage positions. So we are trying not to be too specific on results in those areas. There are other areas which you can comment on, where we have largely captured the plays, and really just working through the technical details now. But as I mentioned, we have in the U.S alone about a million net acres in shale plays. So it's a very substantial position. Over to you, Jeff.
Jeff Wojahn - Executive Vice-President & President, USA Region: Good morning Mark. You know I can comment a little bit on some of the plays which we have talked about in the past. In the U.S, it is very much a year of evaluation for gas shales and I’ll go down the list, and some of these place you may be already aware of. In the Piceance Basin, we believe the Niabrara has potential over about 400,000 acre area. This is a zone that we have done some vertical testing on, but we are now going to proceed to drilling some horizontals this year. We have about 400,000 acres over a prospective area, on our 900,000 acres plus in the Piceance Basin. So you don't hear much of industry talking about it and the reason why, is because own it. But we are talking about it now, so you will hear more about that play when we have some more results. The Pearsall play, the Pearsall Shale in the Maverick Basin is an area of current activity. We have a joint venture partnership with TXCO. We plan to drill three wells this year. We have one well completed and it's producing gas right now. More to come there, we’ve 167,000 net acres on that play. Of course, the Delaware Barnett Shale play we are partners, joint venture partners with Chesapeake. We have a little bit under 300,000, 287,000 net acres on that play and we are working our way through a nine-well commitment program, as we speak there. And we have some interesting early results there as well. And of course the Barnett Shale is one of our key resource plays, we have about 150,000 net acres on that play. As Randy mentioned, we also have some plays that we are not going to talk about today. Above and beyond the ones I mentioned, but even just adding up to the ones that I have just talked about, I think you can get yourself to a million net acres.
