I would say, in terms of the spec pools, I mean, we're not -- some of the higher coupon made a kind of break between things, sort of a super premiums, 5.5s and higher, and 5s and under. And the 5.5s and over, I almost characterize as kind of museum pieces. They've run up a lot. TBA is just awful in those, and I think a lot of the pay up increases have been more of the TBA is terrible, given, if they are right in HARP wheelhouse, they're not going to look very good. So those are -- we're just letting them do their thing. They are still very paying very, very well, a lot of balance paper in those coupons that we own. In general, with higher pay ups, our thought is that in a rate backup, sort of buying IOs, would you want to own IO in that case? So I don't know that I'd necessarily agree that higher coupons would underperform lower coupons in a backup. Anyway, I guess we'll see what happens, if that ever does happen. So in terms of what we're buying now, certainly, during the quarter, we bought across all the different sectors of agency mortgages. We did buy a decent amount of hybrid ARMs, which we thought looked pretty attractive earlier in the quarter versus 15. And we are adjusting some of what we're buying in terms of mix, buying some more sort of investor property pools, some maybe slightly higher loan balance pools -- not the lowest low balance pools, trying to minimize some of the pay ups there for cost. But I mean, that's kind of what we're doing. It's not like -- I wouldn't characterize that the specified pool market is incredibly cheap, but it's certainly -- there are spots that we think that look attractive.
