So, maybe I’ll start Doug. I think from a property perspective, we want our borrowers to succeed in their business plans. We expect our borrowers to succeed in their business plans and we think it’s very likely that our - succeed in the business plan and what is probably the least predictable, if you want to call back is the timing of when they can achieve those results. And so again, why we are very specific, we are very on top of our assets, we think we know what’s going on step by step as they reposition and further add value and cash to these assets. It's really the timing of when they achieved those results that could impact our prepayment reductions or assumptions either slower or faster. So, again, I think that from a loan-by-loan perspective is the biggest factor and when prepayments can happen. So, good news is sometimes not great news for us right because of the borrowers very successful and does it faster than they expect the faster than we expect, it’s likely though to accelerate that prepayment. Great news for the borrower great news from creation of value, unfortunately not so great news in terms of having an earlier prepayment then what we have projected. On the opposite sense again, if one of our borrowers takes longer than expected, obviously not great news in terms of executing the business plan, but good news in terms of holding on the asset longer, but still overtime, generating the value increase and cash flow increase that we expected. So, from a property by property perspective I think that is one impact. From a capital market standpoint, obviously if there was a sharp decrease in borrowing spreads where one of our borrowers said, hey I can, even though I haven’t completed my business plan, I can get cheaper financing today than what I have with the team for maker and they can try to refinance. We have not seen evidence of that very much in the past for a couple of reasons one is we do have some lockout protection of our loans that generally in a three-year loan will have anywhere from 12 to 18 months not in all cases, but in general we’ll have 12 to 18 months of lockout protection. And secondly, we build an upfront fees that in many cases we build in exit fees, so that it acts as somewhat of a barrier, if you want to call that, but somewhat of a discouragement to pay us early because those fees are going to be fully due whether they prepay us at whole maturity or they prepay as prior to that time period, so there are some things we can do to discourage prepayment even in the scenario of much lower borrowing spreads, but again I think those two would be the two ways to really think through and say, how could prepayment speeds impact our business.
