That's a million dollar question. It's a great question. I think the first thing is obviously, what we've been really eyeing is cash flow coverage during this, as we talk to our tenants. On our portfolio, to gauge how quickly they are moving and while our numbers that I quote every quarter which is the top 15 as we are looking backward number. What we've tried to do lately, as we're doing underwriting, may be in the past, we would have said, at this point in a year show me your '07 numbers, show me your '06 numbers and see if you can get me an update, to underwrite that. We are now saying, show me your last 12 months trailing and quite frankly, I don't really care about and what's these big seasonal adjustments, the 6 months from the back end to that, I want to see your last 8 weeks, and what you're hearing from your stores. I think we're really tightening up the number we're trying to use for cash flow coverage's and then if we were looking for a 2.5 in the past, I'd say, we'd be looking for 2 and 3 quarters and a 3 today, because as always, it's margin of safety. And then it'd be really trying to focus in, on the real estate side of the risk and not get too far away from replacement cost and then just be mindful of their industry. We're not doing any restaurants, but an example, might be if we were doing upper end restaurants and you look at their trailing 12 months and the numbers look just fantastic which some of them do. I think if you look at the last 6 to 8 weeks and their numbers, you'd be looking at, it really declining and I would say that you may see it decline quite a bit more. So industry specifically, I think we'd be careful. So in this, we're going to have a higher cash flow coverage. We don't want to get away too far from replacement cost and then we just want to think too carefully where they are going. But at this point not buying anything, we haven't had to do that.
