Yes, Austin, this is Sean, happy to take that one for you. It's in the supply in Southern Cal, yes, we do expect to increase year-over-year from 1.6% of inventory to about 2.3 to 70 basis points. As I mentioned in my prepared remarks, just first on this cycle is exceeded 2%. We don’t think it's going to last one frankly because supply in '19 is projected back down at about 1.2% of inventory. There is a number of things potentially driving that and the pipeline make it more constrain in certain markets like Los Angeles, which has, as you may know, passed the JJJ ordinance, which is imposed new affordable requirements and other things on developers that make the economics quite challenging. But in terms of what’s expected for 2018, the biggest groups is really in LA, we are going from about 9,000 units to 15,000. Orange County is up about 1,500 units to about 7,400, and then Santiago about 2,400 units to about 6,000 in total, which is fairly heavy amount for somewhat smaller markets. In terms of your question about concessions and such, it's in the sub markets where we would have expected it, so at Santiago it's not significant at all, but for the most you see it in Downturn Santiago in terms of the concentration of supply, and therefore more concessions. In Orange County, it tends to run in Irvine, Anaheim and a little bit Huntington Beach where you see concessions, but again we're not talking about significant levels here. And then LA, it's -- where it’s a little bit to play heavy so you see some concessions in Downtown LA, for sure, which is where a heavy amount of supply is being delivered and we'll continue to be delivered in 2018, and then that includes Korea town as well. So, Downtown LA create sound, there is a healthy amount of supply there and then the other concessions that really kind of in the West Hollywood, Hollywood, Mid-Wilshire portion of LA. So we're not material in terms of maybe what we saw when we opened some deals in San Francisco last year, but I'd say in terms of any concession activity that slightly above the norm, those are bit of submarkets that become mind.
