Let me stress the philosophy you are asking about, first don't kind of get to the cost of newness. It's really just the philosophy of what we're doing. And that is -- as Hap mentioned, the world is rapidly changing, I read a quote that said, customers live in an ever-increasing sensory-stimulating world that elevates their requirements for uniqueness. And basically the millennial today are just saying, we hear this when we sit down with the retailers and we talk to them that newness is important, they want exciting, they want updated brand. They just don't want the same old, and they are impatient. They want immediate gratification, which includes customer service and just the whole experience they get. They are not anti bricks and mortar, they are comfortable in both the real world, additional world, but if you're going to bring them to your centers, you got to make it as fresh and exciting as you can. So with that in mind, there is three prongs to get to improving that experience. One is the merchandising where we want to attract, really we want to attract the best tenants we can for the center whether that's one of our higher end centers or our bread and butter, expand the trade area with them, and therefore attract other better retailers, attract more traffic, which would grow sales, which would create a virtuous cycle that'll lead to higher NOI. And we've got lots of examples of that; we got in our Westlake development, Le Pain Quotidien, Pitfire Pizza there, Mendocino Farms we talked about. We talked about in the call Bartaco. So part of part of this merchandising, the second part is twice making it. We just want to make it a more inviting experience. You know this was a center you like to go to, you like to kind of just hang out there versus the ones you can't wait you to kind of get in and out because shopping done. And then the third thing we just speak connecting to the community and that can be technology with a social media the like, or it can just having the kind of tenants and having the kind of design that allows for things like sponsoring a 5K race. One of our tenants at Cameron Village is a fitter store, and they work these post work up pub crawlers with all of the restaurants and everything, so that's kind of theory. In terms to the cost the cost really having proving to be an issue yet. If you look at that Bartaco deal that we talked about in Atlanta, the return cost for doing that deal was over 10%, about 10.5%. If you look at Westlake village there is really four of these transformational tenants that we brought and the TIs are $25 to $30 per square foot. But including that $25 to $30 per square foot are money there are going to have to spend to do work that we would normally do. For example, we did not deliver restrooms or lighting. The restaurants want to provide their own restrooms and lighting. So that brings your TIs down to more like the $15 square foot range, which is very, very typical of what we do. I do think with these kinds of attention you can expect that TIs will go up somewhat, but again we're not going to do it unless we think the overall impact is going to be raise NOI for the entire center. And then I would say in terms of cost for each individual center, if it is a redevelopment, it's going to be part of redevelopment cost, where it's no part of redevelopment, I think expense on the centers, some centers might be $100,000 and others it could be as low as $10,000. So it's really going to depend on which profits we are talking about.
