I don't think it's a trend quite yet. It's something that we suggested in our first environment report back in 2007 and that we brought up again in our most recent one, in 2016. It's something that I don't think has caught on yet, just because I don't think there's a lot of information available out there for it.
One of our recommendations is really to provide education to business owners and landlords, because business owners may have more incentives to request such a lease from their landlord if they even know it exists.
As far as I know, it hasn't really been something that has caught on fully yet.
