Earnings per share for the quarter increased 24% from the second quarter results of $0.59 per diluted share. In addition, the Board of Trustees of PMT has declared a cash dividend of $0.50 per common share of beneficial interest, the same amount declared for the prior quarter.

This is presented on the Company’s balance sheet as mortgage loan assets and related financing of mortgage assets. At the end of the quarter, the Company’s portfolios of residential mortgage whole loans and REOs were valued at $938 million, an increase of 33% from the previous quarter.

The Company’s distressed mortgage loans generated realized and unrealized gains totaling $32.3 million in the third quarter. Of these gains, $8.5 million was realized through payoffs, the result of collections on the loan balances at levels higher than recorded fair values. During the quarter ended September 30, 2011, the Company recognized valuation gains totaling $23.8 million. The following is detail of the realized and unrealized gains on mortgage loans for the third quarter:

Valuation changes		$23,767
Payoffs		8,544
		$32,311

Expenses for the third quarter of 2011 totaled $17.1 million, compared to $12.2 million in the second quarter of 2011. This increase was largely attributable to increases in interest expense of $2.2 million and loan servicing fees of $1.2 million. Servicing costs increased with the growth in managed assets and increased activity of the portfolio, which grew by $343 million in unpaid principal balance during the third quarter. Interest expense rose due to an increase in the amount of mortgage assets financed. The weighted average interest rate on borrowings for the third quarter was 3.67%.

During the third quarter, PMT entered into a $40 million master repurchase agreement with Wells Fargo Bank, N.A. The facility is committed for a period of 364 days and can be used to finance non-performing loans (NPLs). With the addition of this facility, PMT’s total available credit for NPLs and REOs increased to $590 million, $323 million of which had been drawn as of the end of the third quarter. PMT has pledged $689 million of its NPLs and REOs to secure this capital.

Stanford L. Kurland, chairman and chief executive officer of PMT, stated, “PMT today reported another strong quarter, driven by consistently solid returns on our distressed mortgage investments. We have continued to add selectively to our portfolio, while maintaining prudent leverage and aggressively extending our successful track record of loan resolutions. We continue to build our portfolio of distressed assets by utilizing innovative techniques, such as purchasing loans through the forward trade, which we announced last quarter. PennyMac Loan Services, PMT’s servicer, continues to progress through the whole loans portfolio at a steady pace, maintaining its high rate of loan resolutions.

“The opportunity to continue to acquire legacy mortgage assets should continue for the next couple of years,” continued Mr. Kurland. “Over that time, we look to continue our leadership in the acquisition of distressed mortgage assets, while expanding our funding levels in the correspondent lending market. We continue to see growth opportunities in the correspondent business and are targeting volume reaching $1 billion per month by the end of 2012.

“We believe the mortgage market is in the midst of a transformation,” Kurland concluded. “As regulators introduce new capital requirements for banks, reform the GSEs, seek to reduce the mortgage market concentration of the large banks, and grapple with legacy issues of the past few years, new non-bank mortgage entities are uniquely positioned to serve an important role in the new mortgage landscape. With the capabilities of its investment manager and servicer, we believe PMT is very well positioned to fill the void left by the large banks and to offer our investors attractive long-term value.”

Management will host a live earnings and investor day webcast which, along with a slide presentation, will be available in the Investor Relations section of the Company’s website at www.PennyMacMortgageInvestmentTrust.com beginning at 5:30 a.m. (PT) on Thursday, October 27, 2011.
