Thanks, Don. As Rich emphasized, we've had a very strong start to 2012. Assets values are up across each sector of the portfolio. We have improved our risk position by reducing the leverage on our credit assets, and our portfolio is well positioned to provide a stable dividend going forward.
The most significant increase was seen in our CMBS portfolio, which contributed $0.80 per share in book value. CMBS 2.0 bonds were especially strong as investor demand for quality bonds pushed yields lower.
The non-agency book also benefited from the price rally and contributed $0.59 per share. We also saw pricing on our specified pool agencies move higher. Valuations reflected the excellent actual prepayment performance of these pools and contributed $0.40 per share of book value.
Finally, swap rates were slightly higher, adding an additional $0.15 per share. The improvement in our portfolio values added $234 million in additional equity for the quarter, which allowed us to reduce leverage while increasing our average portfolio by 9%.
Let's turn to Slide 5 to see the impact of the additional equity. Slide 5 provides a snapshot of the portfolio at quarter end. The overall leverage in the portfolio decreased from 6.4xto 6x. As I'll discuss in more detail in a moment, the composition of the leverage has changed.
The increase in asset value to -- served to improve our equity position. Roughly $190 million in equity was added to the credit book, and about $60 million was added to the agency book. We also received cash as we liquidated the bond side of our PPIP investment.
The reduction in credit leverage where we shifted our borrowing mix away from higher-cost repo served to reduce risks while keeping asset levels constant. The additional capital in the agency space allowed us to add more MBS assets, where we continue to find good opportunities in specified pool paper.
Moving to Slide 6, you'll see it was a very good quarter for our agency book. Higher-coupon agencies outperformed swaps, and the pay ups at our specified pool paper increased materially.
We opportunistically added assets throughout the quarter and continue to find good opportunities in this sector. We focused primarily on longer-dated hybrids, as they were attractive relative to 15s. The hybrids have appreciated materially. We also bought more 30-year prepaid protected pools focusing on geographic, FICO and other credit stories.
Net interest margin increased by 16 basis points to 140 basis points. This was driven primarily by high-cost year-end repo rolling off, as well as by a slightly lower hedge ratio, as no new hedges were added in the quarter.
The prepayment rate in the portfolio continues to be remarkably slow, as our fixed rate collateral paid a bit over 10 CPR. Our 3-month speed slowed by 14% quarter-over-quarter and our fixed rate book paid at roughly half the rate of comparable generic collateral.
Looking ahead, we still believe that agency mortgages look attractive despite their recent performance. Technicals are very positive, with limited supply and robust demand out of banks, insurance companies, REITs, as well as the Fed. And it's important to note that capacity constraints and borrowers' continued inability to qualify for credit has reduced the convexity risk of the sector.
Moving to Slide 7. It was also a very good year -- start to the year for credit assets, particularly for high quality credit assets, which is where our portfolio is concentrated. On previous calls, we've talked about the need for yield in the marketplace and how high quality cash flows would benefit, as investors are forced away from Treasurys by extremely low yields. This is exactly what we've seen this year.
In non-agencies, we reduced leverage to 2.77x from 4.07x. There are a number of factors that allowed us to accomplish that. We paid down $218 million in borrowings on non-agencies through a combination of cash paydowns, factoring [ph]changes and bond sales.
We also saw an increase in OCI of around $68 million as assets prices went up. This increase in equity in the sector led directly to the reduction in leverage without materially changing the amount of dollars we have invested in this sector. This allowed us to capture the price rally in book value, while repositioning our borrowings.
We believe these moves leave us well positioned. Reduced leverage on the credit book reduces risk as banks' willingness to lend on credit is impacted by macro events. This also leaves us with plenty of dry powder to capitalize on future opportunities. Even with the reduction in leverage, our high-quality book still generates ROEs in the mid-teens, allowing us to maintain our earnings power.
I'll finish up on Slide 8 and CMBS. It was a very similar story in the CMBS sector, as the demand for high-quality assets remained robust and led to significant increase in asset prices. The CMBS 2.0 bonds that we owned, for example, were up on average 10 points during the quarter. In fact, we have seen this demand carry over into the current quarter with a successful disposition of the latest Maiden Lane bid list. We reduced leverage slightly in CMBS to 2.4x, as some minor repositioning as well as an increase in OCI combined to increased equity by $45 million.
The CMBS book continues to generate an ROE in the mid-teens, with the added benefit of reducing the convexity risk of the portfolio. We continue to see good opportunities in this sector as well. We were able to add some assets recently as we participated in the Maiden Lane sale, and we will selectively add assets as they become available.
One final thought. We stated in our previous earnings call in February that our goals for the first quarter were to reduce credit leverage, given the volatile macro landscape; to continue to improve book value; and to maintain a stable dividend. We plan to continue to emphasize those 3 areas in this market environment.
With that, I'll open the floor to questions.
