Thank you, Brad, and good morning, everyone. This was a great quarter with respect to our portfolio performance, especially considering our conservative positioning. We are also proud to report several meaningful accomplishments within our mortgage loan conduit.
Let's turn to Slide 8. Our rate strategy performed well this quarter, driven largely by our positioning in shorter-duration assets and from a curve-flattening bias in our rate hedges.
We repositioned our hedges to protect against higher short-term rates in 2015 and '16, which contributed nicely to our performance as the curve flattened during the quarter.
Our credit strategy was driven by legacy non-Agency bond price appreciation, which contributed to our book value performance. The yields realized in our rate strategy decreased 20 basis points quarter-over-quarter to 3.6%. Despite this, we are pleased with the stable long-term performance of our Agency RMBS assets and the incremental yield provided by MSR. For example, in the third quarter, realized yields in our rate strategy were up 80 basis points year-over-year, due in part to our incremental investment in MSR.
Within our credit strategy, the yields on legacy and new issue non-Agencies were generally consistent with the second quarter. Our net economic interest in securitization yield declined as we chose to retain some of the AAAs from our securitizations, specifically those from the Agate Bay 2014-1 deal, due to their healthy projected ROEs. Going forward, we expect the yield on our net economic interest and securitization trust to increase as the amount of retained subs and IOs grows as a percentage of our retained interest.
Our aggregate portfolio generated an annualized net interest spread of 3%, down about 40 basis from the second quarter. This was principally driven by higher overall swap expense from 2- and 3-year swaps, which we will detail later as part of our hedging discussion.
Please turn to Slide 9. Our portfolio as of September 30 was $14.3 billion, including $10.4 billion in rates and $3.9 billion in credit. Approximately 56% of our capital is allocated to our rate strategy, including 44% to Agency and 12% to MSR. The remaining 44% of capital was allocated to our credit strategy with 7% to our conduit business.
We made 2 adjustments on the asset side of our portfolio during the quarter. First, we sold approximately $1.25 billion of MHA and low FICO pools, as we believe that, with the improvement in housing prices, these pools might lose their prepayment protection and show faster prepays going forward. We replaced them with lower loan balance pools, which we expect will demonstrate more stable prepays over time.
Second, we finished selling the remainder of the longer-reset ARMs that we held. You may recall we were trimming this position in the second quarter, as these assets returned to unattractive levels. We still own a few very seasoned ARMs that, from a risk and return profile, fit nicely in the portfolio.
In general, opportunities in the Agency space remained limited during the quarter. And as such, we continue to have low leverage on our Agency RMBS portfolio. We are also keeping our basis risk exposure low by focusing on shorter-duration Agency assets and through our MSR holdings, both of which serve to protect against the impact of potentially wider spreads in the future.
Our credit portfolio remains weighted toward legacy non-Agency RMBS, particularly sub-Prime. Last quarter, we released a webinar profiling a sub-Prime bond we held in our portfolio, housing price appreciation over the past few years and how the bond outperformed our original return assumption.
Today, affordability is about 26% better than the historical mean, which indicates that homes are still quite affordable. Therefore, we expect there could be continued home price appreciation performance over the next several years. With the average market price of our non-Agency bonds in the mid-70s, we believe upside optionality remains as the economy and housing market continue to improve.
While we have significant legacy non-Agency holdings, we're also excited about the opportunity our conduit business present and have increased our capital allocation to this platform from very little exposure at December 31 to over 7% at September 30. From a market value standpoint, our total net economic interest and securitization trust increased by approximately $250 million quarter-over-quarter to $490 million, as we retain the aforementioned AAAs, along with the subs and IOs.
Finally, our prime jumbo mortgage loans held for sale increased to $419 million this quarter versus $377 million at June 30. As a result, we expect our capital allocation to assets generated by the conduit to increase over the next few years. More on our conduit progress in a bit.
Turning to Slide 10. You will see that our leverage remains low, with our implied debt-to-equity ratio for RMBS Agency derivatives and mortgage loans held for sale, net of TBA, at 2.7x. Our Agency prepayments remain low and stable, dropping a bit in the quarter. Given the recent rally in rate, it is worth a reminder that over 96% of our Agency holdings are prepay-protected.
On the non-Agency side, however, prepays were higher in the quarter, which, given the deep discount of our holdings, is very beneficial.
Moving to the right-hand side of the slide. There are a few items I would like to discuss with respect to hedging that Brad touched on. During the quarter, we reduced our swaptions notional by approximately $4 billion and extended the maturity from 3 to 5 years. To offset this, we increased our notional swap position by up about $4 billion with a focus on the front end of the curve. This repositioning intends to protect against potentially higher rates in 2015 and '16 if the Fed decides to raise interest rates next year. It also creates a flattening bias to our hedges, benefiting if short rates rise faster than long rates.
This helped drive our performance in the third quarter. Overall, we continue to be positioned conservatively with low interest rate and basis risk and also low leverage. For more on our rates and credit holdings, please refer to the appendix, Slide 18 through 22, and see Slides 24 and 25 for more information on our hedging.
Turning to Slide 11. Our mortgage loan conduit was certainly a highlight of the third quarter. We completed 2 securitizations, Agate Bay 2014-1, a $268 million deal; and 2014-2, a $374 million deal. Additionally, our pipeline, which includes our prime jumbo loan and interest rate lock commitments, was approximately $750 million at September 30.
We expect this pipeline to lead to one securitization in the fourth quarter and tee up another for early 2015. We are excited about the maturation of our conduit program. We had 28 originators on our platform at quarter end, with more expected to be approved by the end of the year. As mentioned earlier, our FHLB facility was expanded to $2.5 billion during the quarter, which helps us efficiently provide permanent capital to the U.S. mortgage market. The long-term nature of this funding allows us to provide stable and consistently attractive pricing to our originator partners, both of which ultimately help homeowners finance the purchase of a home.
Please turn to Slide 12. While our conduit efforts have thus far been focused on sourcing prime jumbo loan, we are pleased to announce that we launched high-LTV and non-Prime programs post quarter end. Our high-LTV program is an extension of our current prime jumbo program, as it is focused on higher credit quality borrowers who need or desire to make smaller down payments in order to purchase a house.
Our non-Prime program provides products to meet the needs of borrowers with average credit quality who, so far, have been unable to get a loan due to the extremely tight credit standards that exist in the market today.
Given that we have just rolled out these products, it is important to note that it will likely take time to drive volumes in these programs. That said, it has been clear to us for some time that the market has a need for products like this, and we are excited to able to extend our reach as a capital provider to these segments of the mortgage market.
Finally, let me touch briefly on MSR. We remain pleased with the ramp of our flow arrangement with PHH, under which we added approximately $700 million UPB during the quarter. We are working on and anticipate adding more MSR flow sellers during the remainder of the year and throughout 2015.
A key benefit to our platform is the ability to cultivate a large network of sellers that we can use to access a variety of products, including MSR, prime jumbo, non-Prime and high-LTV.
In closing, we are excited about the potential for our business as our operational platform gains traction and with the launch of new products aimed at providing solutions to the quandary facing the mortgage market today. We remain focused on the creation of total return for our stockholders and are vigilant with respect to the protection of book value.
I will now turn the call back to Ben, and we would be happy to take questions.
