So Mark this is Russell. I mean as we stated when we first completed the merger with Plum Creek that we are going to look at all of the components of the portfolio and we divested the Uruguay operations kind of as part of that review. And then we continued to look at the portfolio really in all regions and determined which timberlands make sense on a long-term basis which are strategic and where we want to grow and where we might want to divest. Again that's an ongoing process. The one thing we'll say about the North is their very low input costs, so it's very low cost type operations. But again we'll continue to review the portfolio and if it makes economic sense we'll act on that.
