The Company’s average earning assets increased to $16.2 billion for the third quarter of 2011 from $15.0 billion in the second quarter of 2011. The Company’s net interest margin decreased to 1.64% for the third quarter of 2011 from 1.97% in the second quarter of 2011 as portfolio yield dropped and the Company’s cost of funds (including hedges) increased 0.02% to 1.08%. The Company’s average repurchase agreement (repo) rate increased to 0.29% in the third quarter of 2011, from 0.24% in the second quarter of 2011, on all outstanding short-term (less than 30 days) repo positions. The Company realized gain on sale of mortgage-backed securities (MBS) of $13.3 million during the quarter compared to $4.4 million for the previous quarter.

“Our flexible portfolio enabled us to effectively manage through a volatile quarter, producing strong returns for our shareholders while protecting book value”, said Michael R. Hough, the Company’s Chief Executive Officer. “We reduced exposure early in the quarter and slowly repositioned into better performing assets as market conditions stabilized and clarity emerged regarding the near term direction of interest rates. As we anticipated, prepayments increased moderately and within our estimates and we ended the quarter with a portfolio that is well positioned for the current environment.”

Dividend

The Company declared dividends of $1.00 per share of common stock with respect to the quarter ended September 30, 2011, which equaled the $1.00 per share dividend for the quarter ended June 30, 2011. Based on the closing share price of $25.16 on September 30, 2011, the third quarter dividend equates to an annualized yield of 15.9%.

Portfolio

The Company’s portfolio, consisting of Fannie Mae and Freddie Mac guaranteed mortgage securities (agency securities), increased to $17.6 billion at September 30, 2011, compared to $16.4 billion at the end of the previous quarter. The portfolio’s weighted average coupon was 3.54% for the third quarter of 2011, compared to 3.61% for the second quarter of 2011. The annualized yield on average assets declined to 2.72% for the third quarter of 2011, compared to 3.03% for the second quarter of 2011 as a result of the lower average coupon and increased premium amortization. The annualized cost of funds on average liabilities (including hedges) was essentially unchanged from the prior quarter at 1.08% in the third quarter of 2011, compared to 1.06% in the second quarter of 2011.

At September 30, 2011 the Company’s portfolio of agency securities consisted of 93.6% of adjustable-rate MBS and 6.4% of 15-year fixed-rate MBS. At September 30, 2011 the Company owned $16.5 billion of adjustable-rate MBS with a weighted average coupon of 3.56% and a weighted average cost basis of $102.39, and $1.1 billion of 15-year fixed-rate securities with a weighted average coupon of 3.13% and a weighted average cost basis of 103.56. The Company’s adjustable rate MBS portfolio at September 30, 2011 is summarized below.

During the third quarter of 2011, the expense of amortizing the premium on the Company’s securities was $30.1 million, compared to $17.8 million during the second quarter of 2011. The increase was the result of a larger portfolio of agency securities and faster prepayment speeds. The weighted-average principal repayment rate (scheduled and unscheduled principal payments as a percentage of the weighted-average portfolio, on an annual basis) during the third quarter of 2011 was 28.6%, compared to 18.5% during the second quarter of 2011. The Company’s weighted-average one-month constant prepayment rate (CPR) for the quarter ended September 30, 2011 was 21.7, as compared to 14.9 for the quarter ended June 30, 2011. CPR measures unscheduled repayment rate as a percentage of principle on an annualized basis.

Portfolio Financing and Leverage

At September 30, 2011, the Company financed its portfolio with approximately $15.9 billion of borrowings under repurchase agreements bearing fixed interest rates until maturity with 23 different counterparties. The Company’s repo debt-to-shareholders’ equity ratio at September 30, 2011, was 7.9 to 1, increasing from 7.4 to 1 from June 30, 2011, and averaged 7.3 to 1 during the quarter ended September 30, 2011. The Company’s repurchase agreements had a weighted-average term of approximately 24 days. The Company also uses interest rate swap agreements to synthetically extend the fixed interest period of these liabilities and hedge against the interest rate risk associated with financing the Company’s portfolio. As of September 30, 2011, the Company had in place, with 13 different counterparties, interest rate swaps with a notional amount of $7.5 billion. The swap agreements, which are indexed to 30-day LIBOR, have a weighted average remaining term of 36 months at a weighted average fixed rate of 1.82%.

Book Value

The Company’s book value (shareholders’ equity) per share on September 30, 2011 was $26.32, down $0.40, from the per share book value of $26.72 on June 30, 2011. On a per share basis, the book value at September 30, 2011 consisted of $24.79 of common equity, $0.01 of retained earnings, $4.56 of unrealized gains on agency securities, and ($3.04) of unrealized losses on interest rate swaps.

HARP Expansion

On October 24, 2011, the Federal Housing Finance Agency (FHFA) announced that it is revamping and expanding the rules regarding the Home Affordable Refinance Program (HARP) with intent of increasing significantly the number of homeowners eligible to refinance their mortgage under this program. While final guidance is not due until November 15, 2011, the FHFA announced the relaxation of underwriting guidelines, such as loan-to-value, appraisals, and certain fees, among other things, subject to a variety of qualifications. It does not change the time period which these loans were originated, maintaining the requirement that the loans must have been guaranteed by Fannie Mae or Freddie Mac prior to June 2009. The Company does not expect this announcement to have a significant impact on its results of operations. The following table shows the Company’s loan portfolio which could be impacted by this program.
