Let me add one point here because it is a really important point -- and you hear a lot of conference calls, everyone want to talk about their strategy doing X, Y or Z. You are in global environment that we could grab from my careers, there's no rate absolute returns per say, they're great relative returns, during zero to negative interest rate environment, and even if the fed increases or rates rise a bit, you are in a zero to negative interest rate environment, and the probability that there's a fed policy here is extremely high, but this environment is backed up on further defined by an enormous amount of global debt, conflicting governmental policies, and that's the backdrop. So we talk about spread moving here, spread moving a little spread movement is that -- yes, we are sticking with our strategy, we would in a major business decisions we think about it historically, in 2014 we went up in credit, we got out of our low credit rating instrument, and we've got a philosophy of high in term to move our overall credit exposure, so with agency in AAA, and spread may move around, they may tighten, they may widen which we try to lean on that the CBS products, a shorter duration instrument, that actually amortizes the rolls that occur similar situation in terms of agency ARMS. So spread may move here or there, you hear a lot of stories about this relative value; this strategy, that strategy; we're sticking to our thought process, and there is a defining moment in early 2014 where we said, we believe the overall global environment is complex and fragile but we made some major adjustments at that time. We haven't shifted, we've still got our agency ARMs, we still got our CMBS exposure, our CBS is heavily there because we have not taken-off the table that you could have a materially surprising low -- lower rate environment meeting where we are today, so we're protecting ourselves repayments, that's come through this year, that's come to in a big way, we're very happy with it. So I'm only adding that in there, because it's just spreads -- not I'm not turning over with these types of spreads, with these type of variations in terms of the spread sheet, we got a philosophy in terms of how we structure this portfolio, will believe in it over the long-term and at the end of the day, the old cliché, we're sticking with it.
