“PMT’s results for the second quarter were driven by strong growth across our correspondent and investment activities,” said Chairman and Chief Executive Officer Stanford L. Kurland.  “During the quarter PMT’s correspondent volume grew to new highs and we added to our portfolio of distressed whole loans through four acquisitions.  Through PCM, our manager, and PLS, our servicer and fulfillment provider, we exceeded our target for correspondent of purchasing $1 billion per month in June by over $400 million and continue to see excellent resolutions in our distressed portfolio.

Achieving a return on average equity of over 17 percent during the quarter in which we raised over $200 million in new equity capital demonstrates our ability to quickly and effectively deploy new capital into accretive transactions.”

During the quarter ended June 30, 2012, PMT recorded investment income on financial instruments totaling $62.0 million, as detailed on the following table:

(1)   Amounts in this column represent accrual of unearned discounts

(2)   Total return represents the sum of the interest yield and the net gain on the respective investment and does not take into account expenses associated with managing the asset.

“Investment income from financial instruments increased over 50 percent from the first quarter of 2012, driven largely by the increase in gains on our correspondent activity and on our whole loan portfolio,” continued Mr. Kurland.  “Net gains on our distressed whole loan portfolio totaled $27.3 million.  Correspondent lending generated another $18.0 million in gains from mortgage loans acquired for sale.  PMT’s strategy continues to evolve with the current market environment and we believe the Company is well positioned to continue its growth.”

Correspondent Lending

During the quarter, correspondent lending funded $3.4 billion in UPB of loans, and IRLCs amounted to $4.6 billion, compared to $1.8 billion and $2.3 billion, respectively, in the first quarter of 2012.  Of total correspondent fundings, conventional loans amounted to $1.8 billion, FHA loans were $1.6 billion, and jumbo loans were $2.6 million.

Pretax income attributable to the correspondent lending segment was $12.0 million for the quarter, primarily driven by an $18.0 million net gain on mortgage loans acquired for sale and $3.2 million of interest income.

The following details the composition of net gain on mortgage loans acquired for sale in the second quarter of 2012:

Distressed Mortgage Investments

PMT’s distressed mortgage loan portfolio generated realized and unrealized gains totaling $27.3 million in the second quarter of 2012 compared to $11.1 million in the first quarter of 2012.  Of the gains in the second quarter of 2012, $6.5 million was realized through payoffs, which resulted from collections on the loan balances at levels higher than their recorded fair values.  Valuation gains totaled $20.9 million in the second quarter of 2012, compared to $6.3 million in the first quarter of 2012 and were primarily driven by the Company’s portfolio of nonperforming whole loans.  The major contributing factors to the increase in valuation gains on the portfolio were stabilizing home prices, the continued progression of loans towards their ultimate resolution, and growth in the size of the investment portfolio.

Expenses

Expenses for the second quarter of 2012 totaled $26.4 million, compared to $22.1 million in the first quarter of 2012.  The increase is primarily attributable to the overall increase in correspondent activity, which resulted in increased loan fulfillment fees in line with that growth, as well as increases in professional services and management fees.  Professional services increased to $1.2 million in the second quarter, from $442,000 in the first quarter, due to diligence fees relating to the acquisition of distressed assets during the second quarter.  The increased expense associated with the management fee resulted largely as a result of the increased equity of the Company.  PMT’s effective income tax rate remained at 22% for the quarter, flat from the first quarter.

Stanford L. Kurland, Chairman and Chief Executive Officer of PMT, concluded, “The Company continues to demonstrate strong performance and growth across its business segments.  We believe we are currently in a unique window of time in the restructuring of the mortgage markets, and there are numerous opportunities in front of PMT.  We are seeing more opportunities in the market today for mortgage assets than we have at any other time in the Company’s history and feel PMT is well positioned to capitalize on these opportunities.”
