Full-Year 2016 Highlights

“PMT’s fourth quarter earnings reflect contributions from its credit and interest-rate sensitive strategies as well as its correspondent production activities. Credit risk transfer investments and correspondent production delivered strong performance; however, the distressed loan portfolio underperformed expectations,” said Executive Chairman Stanford L. Kurland.  “Returns on our net interest-rate sensitive strategies were primarily driven by gains on MSRs and ESS resulting from the significant rise in mortgage rates during the quarter.  Correspondent production lock volumes and margins decreased from last quarter’s recent highs, pressured by the increase in mortgage rates and seasonality.  This quarter’s results also included an income tax benefit primarily driven by the performance of interest rate hedges held in our taxable REIT subsidiary, which produced a loss offset by gains on other interest-rate sensitive assets.”  

PMT reported pretax income of $13.9 million for the quarter ended December 31, 2016, compared to pretax income of $45.0 million in the third quarter.

The following table presents the contribution of PMT’s Investment Activities and Correspondent Production segments:

Investment Activities Segment

The Investment Activities segment generated pretax income of $2.1 million on revenues of $26.3 million in the fourth quarter, compared to pretax income of $13.6 million on revenues of $41.3 million in the third quarter. Net gain on investments in the fourth quarter included $18.9 million of gains and recapture income related to excess servicing spread (ESS); $10.4 million of gains on CRT investments; and $7.5 million of gains related to hedging derivatives.  These gains were partially offset by net losses on mortgage backed securities (MBS) of $23.1 million; losses on distressed mortgage loans of $1.0 million; and $0.4 million of losses on mortgage loans held by a variable interest entity, net of the related asset-backed secured funding.

Net loan servicing fees were $7.8 million, down from $15.8 million in the third quarter. Net loan servicing fees included $37.1 million in servicing fees, reduced by $17.9 million of amortization and realization of MSR cash flows. Net loan servicing fees also included $48.6 million of impairment reversals and fair value gains related to MSRs, offset by $60.7 million of related hedging losses. Net loan servicing fees also included $0.7 million of MSR recapture income.  PMT’s hedging activities are intended to manage its net exposure across all interest rate-sensitive strategies, which include MSRs, ESS and MBS.

MSR fair value gains, impairment reversals and ESS valuation gains in the fourth quarter resulted from expectations for lower future prepayment activity due to the sharp rise in mortgage rates during the quarter.  ESS gains also included recapture income totaling $1.8 million payable to PMT for prepayment activity during the quarter.  When prepayment of a loan underlying PMT’s ESS results from a refinancing by PennyMac Financial Services, Inc. (NYSE: PFSI), PMT generally benefits from recapture income.

Net interest income from PMT’s investments was $11.6 million in the fourth quarter, a 6 percent decrease from the prior quarter.  Interest income totaled $41.1 million dollars, a 5 percent decrease from the third quarter.  Interest income included $22.0 million of capitalized interest from loan modifications, which declined modestly from the third quarter due to a reduction in modification activity. Capitalized interest increases interest income and reduces loan valuation gains.  Interest expense totaled $29.6 million in the fourth quarter, a 4 percent decrease from the prior quarter.

Other investment losses were $5.4 million, compared with a $1.1 million loss in the third quarter, driven by REO valuation losses and higher REO expenses due to a seasonal increase in real estate tax payments.  At quarter end, PMT’s inventory of REO properties totaled $274.0 million, down from $288.4 million at September 30, 2016.

Segment expenses were $24.1 million, down from $27.6  million in the third quarter, driven by adjustments to estimates of liquidation expenses, partially offset by $1.3 million in servicing activity fees related to a sale of performing loans from the distressed portfolio.

Distressed Mortgage Investments

PMT’s distressed mortgage loan portfolio generated realized and unrealized losses totaling $1.0 million, compared with realized and unrealized losses of $3.4 million in the third quarter.  In the fourth quarter, fair value losses on the performing loans in the distressed portfolio were $0.6 million while fair value losses on nonperforming loans were $1.5 million.

The schedule below details the realized and unrealized (losses) gains on distressed mortgage loans:  

Income contribution from the distressed portfolio declined modestly from the third quarter and underperformed PMT’s expectations.  The underperformance was driven by increased recidivism of previously performing loans and reduced expectations for future loan performance and recoveries. These factors were partially offset by actual home prices which performed better than prior forecasts.

Mortgage Servicing Rights

PMT’s MSR portfolio, which is subserviced by PFSI, grew to $56.3 billion in UPB compared with $50.9 billion at September 30, 2016.  Servicing fees and MSR recapture revenue of $37.8 million was reduced by $17.9 million of amortization. Impairment reversals and fair value gains totaled $48.6 million, which were offset by $60.7 million of losses on hedging derivatives.

The following schedule details net loan servicing fees:

Correspondent Production Segment

PMT acquires newly originated mortgage loans from third-party correspondent sellers and typically sells or securitizes the loans, resulting in current-period income and ongoing investments in MSRs and GSE credit risk transfers related to a portion of its production.  For the fourth quarter, PMT’s Correspondent Production segment generated pretax income of $11.7 million, versus $31.4 million in the third quarter.

Through its correspondent production activities, PMT acquired $20.0 billion in UPB of loans and issued IRLCs totaling $19.2 billion, compared with $18.9 billion and $21.6 billion, respectively, in the third quarter.  Of the correspondent acquisitions, conventional conforming and jumbo acquisitions totaled $7.5 billion, and government-insured or guaranteed acquisitions totaled $12.5 billion, compared with $7.3 billion and $11.7 billion, respectively, in the third quarter.

Segment revenues were $42.7 million, a 31 percent decrease from the third quarter, driven by a decline in net gain on mortgage loans.  Net gain on mortgage loans acquired for sale in the quarter declined 47 percent from the third quarter, driven by a 20 percent quarter-over-quarter decline in conventional lock volume and lower margins.  Third quarter results also included a $5.1 million benefit in provision for representations and warranties due to a change in estimate.

The following schedule details the net gain on mortgage loans acquired for sale:

Segment expenses were $30.9 million, up slightly from $30.7 million in the third quarter, primarily due to the increase in acquisition volumes.  The weighted average fulfillment fee rate in the fourth quarter was 36 basis points, down from 38 basis points in the prior quarter.¹

Management Fees and Taxes

Management fees were $5.1 million, up slightly from $5.0 million in the third quarter. There were no incentive fees due for the fourth quarter.

PMT recorded an income tax benefit of $17.3 million in the fourth quarter, versus a provision for income taxes of $9.6 million in the third quarter. The income tax benefit was primarily driven by the performance of interest rate hedges held in the taxable REIT subsidiary, which produced a loss offset by gains on other interest-rate sensitive assets.

Mr. Kurland concluded, “While earnings from PMT’s investments in the fourth quarter were lower, largely driven by underperformance of the distressed loan portfolio, the cash flows from PMT’s existing investments remained strong.  As we enter what appears to be a period of higher interest rates, we expect that the mortgage market will normalize from the elevated margins and volumes seen in 2016.  However, robust macroeconomic trends bode well for home purchase demand and PMT’s purchase-money oriented correspondent production.  In addition, higher rates and a vibrant economy are expected to positively impact the performance of the company’s CRT, MSRs, ESS and distressed loan investments.”
