“Our results reflect solid performance in a volatile market environment during the fourth quarter,” said President and CEO David Spector. “PMT’s unique credit risk transfer investments, while somewhat impacted by credit spread widening, continued to deliver solid results and the returns on our Interest Rate Sensitive strategies reflect our disciplined focus on hedging through this period. Our correspondent production activities delivered strong volume growth as a result of our unique execution capabilities, driving continued growth in our CRT and MSR investment strategies.”

The following table presents the contributions of PMT’s segments, consisting of Correspondent Production, Credit Sensitive Strategies, Interest Rate Sensitive Strategies and Corporate:

Credit Sensitive Strategies Segment

The Credit Sensitive Strategies segment primarily includes results from CRT, distressed mortgage loans and non-Agency subordinated bonds. Pretax income for the segment was $17.9 million on revenues of $22.3 million, compared to pretax income of $33.1 million on revenues of $40.0 million in the prior quarter.

During the quarter, PMT continued to deliver to Fannie Mae loans eligible for CRT investments under a new REMIC structure.  The Company also settled its fourth CRT transaction with Fannie Mae in the quarter.

The Credit Sensitive Strategies segment recorded net gain on mortgage loans acquired for sale of $14.0 million, up from $12.3 million in the prior quarter, which represents the recognition of the fair value of firm commitments to acquire CRT securities under the REMIC structure.  The quarter-over-quarter increase in net gain on mortgage loans acquired for sale was driven by the higher volume of loans delivered into CRT investments resulting from increased loan production activity.

Net gain on investments was $12.2 million, down 54 percent from the prior quarter.  

Net gain on CRT investments was $9.8 million, compared to $29.5 million in the prior quarter.  Net gain on CRT investments included $19.6 million in valuation-related losses, driven by declines in fair value from credit spread widening and increased market volatility.  Net gain on CRT investments also included $30.1 million in realized gains and carry on CRT investments, up from $27.0 million in the prior quarter, as well as losses recognized during the quarter of $0.7 million, up from $0.4 million in the prior quarter, reflecting portfolio seasoning and in line with expectations.

PMT’s distressed mortgage loan portfolio generated realized and unrealized gains totaling $2.5 million, compared to a loss of $3.1 million in the prior quarter. Fair value gains on performing loans in the distressed portfolio were $7.7 million, while fair value losses on nonperforming loans were $4.0 million.

Net interest expense for the segment totaled $2.5 million, compared to $0.1 million in the prior quarter.  Interest income totaled $10.2 million, a 17 percent increase from the prior quarter, driven by an increase in deposits securing CRT agreements resulting from the settlement of our fourth CRT transaction during the quarter.  Interest expense totaled $12.7 million, up from $8.8 million in the prior quarter, resulting from the growth in CRT investments subject to financing arrangements.

Other investment losses were $1.4 million, compared to a gain of $1.5 million in the prior quarter, driven by costs related to ongoing reduction of the real estate acquired in the settlement of loans (REO) portfolio.  At quarter end, PMT’s inventory of REO properties totaled $85.7 million, down from $95.6 million at September 30, 2018.

Segment expenses were $4.4 million, down 36 percent from the prior quarter driven by servicing advance recoveries and lower professional services expense.

Interest Rate Sensitive Strategies Segment

The Interest Rate Sensitive Strategies segment includes results from investments in MSRs, ESS, Agency mortgage-backed securities (MBS), non-Agency senior MBS and interest rate hedges. Pretax income for the segment was $20.1 million on revenues of $30.2 million, compared to pretax income of $24.1 million on revenues of $33.2 million in the prior quarter. The segment includes investments that typically have offsetting fair value exposures to changes in interest rates. For example, in a period with increasing interest rates, MSRs and ESS typically increase in fair value whereas Agency MBS typically decrease in value.

The results in the Interest Rate Sensitive Strategies segment consist of net gains and losses on investments, net interest income and net loan servicing fees, as well as associated expenses.

Net gain on investments for the segment totaled $34.5 million, primarily consisting of $39.1 million of gains on MBS, partially offset by a $5.2 million loss in the value of hedging derivatives.

Net interest income for the segment was $3.2 million compared to $5.5 million in the prior quarter.  Interest income totaled $32.9 million, up from $30.6 million in the prior quarter primarily driven by growth in the MBS portfolio. Interest expense totaled $29.7 million, up from $25.1 million in the prior quarter, driven by increased financing costs from higher short-term interest rates and a larger MSR asset.

Net mortgage loan servicing fees resulted in a loss of $7.5 million, compared to a gain of $44.4 million in the prior quarter. Net mortgage loan servicing fees included $57.4 million in servicing fees and $1.4 million in ancillary and other fees, reduced by $34.9 million in realization of MSR cash flows. Net mortgage loan servicing fees also included a $40.9 million decrease in the fair value of MSRs, $8.8 million of related hedging gains and $0.6 million of MSR recapture income. PMT’s hedging activities are intended to manage the Company’s net exposure across all interest rate-sensitive strategies, which include MSRs, ESS and MBS.

Before January 1, 2018, PMT carried the majority of its MSRs at the lower of amortized cost or fair value.  Beginning January 1, 2018, and prospectively, the Company accounts for all MSRs at fair value.

MSR valuation losses were primarily driven by a decrease in mortgage rates at quarter end, resulting in expectations for higher prepayment activity in the future.  ESS investments also declined in value from a decrease in mortgage rates; however, the valuation losses were more than offset by higher recapture income from PFSI for prepayment activity during the quarter.  PMT generally benefits from recapture income when the prepayment of a loan underlying PMT’s ESS results from refinancing by PFSI.

Segment expenses were $10.0 million, a 10 percent increase from the prior quarter, primarily driven by higher servicing expenses on a growing MSR portfolio.

7

Correspondent Production Segment

PMT acquires newly originated mortgage loans from correspondent sellers and typically sells or securitizes the loans, resulting in current-period income and ongoing investments in MSRs and CRT related to a portion of its production.  PMT’s Correspondent Production segment generated a pretax loss of $0.6 million, compared to a profit of $6.0 million in the prior quarter.  

Through its correspondent production activities, PMT acquired $18.1 billion in UPB of loans and issued interest rate lock commitments totaling $19.1 billion in the fourth quarter, compared to $16.6 billion and $17.9 billion, respectively, in the third quarter.  Of the correspondent acquisitions, conventional conforming and jumbo acquisitions from nonaffiliates totaled $9.1 billion and government-insured or guaranteed acquisitions totaled $8.9 billion, compared to $7.5 billion and $9.0 billion, respectively, in the prior quarter.

Segment revenues were $31.0 million, an 11 percent decrease from the prior quarter and included a net gain on mortgage loans of $3.6 million, other income of $15.0 million, which primarily consists of volume-based origination fees, and net interest income of $12.3 million.  Net gain on mortgage loans acquired for sale in the quarter decreased by $8.9 million from the prior quarter, driven by heightened competition for conventional loans during the quarter.  Net interest income increased $2.5 million from the prior quarter, primarily driven by production volume growth and the corresponding recognition of incentives the Company is currently entitled to receive under one of its master repurchase agreements to finance mortgage loans that satisfy certain consumer relief characteristics.  These incentives totaled $8.7 million, up from $5.0 million in the third quarter.  The Company expects that it will cease to accrue incentives under this repurchase agreement beginning in the second quarter of 2019.  While there can be no assurance, the Company expects that the loss of any such incentives could be partially offset by an improvement in pricing margins.

Segment expenses were $31.6 million, up 10 percent from the prior quarter from increased production activity, partially offset by a reduction in the weighted average fulfillment fee during the quarter.  The weighted average fulfillment fee rate in the fourth quarter was 32 basis points, down from 35 basis points in the prior quarter, reflecting discretionary reductions made by PFSI to facilitate successful loan acquisitions by PMT.

Corporate Segment

The Corporate segment includes interest income from cash and short-term investments, management fees and corporate expenses.

Segment revenues were $417,000, down from $611,000 in the prior quarter.

Management fees were $6.6 million, up 1 percent from the prior quarter primarily driven by a 10 percent increase in incentive fees paid to PFSI in the fourth quarter based on PMT’s profitability.

Other segment expenses were $5.1 million, down from $5.6 million in the prior quarter.

Taxes

PMT recorded an income tax benefit of $15.4 million compared to a $5.1 million expense in the prior quarter, resulting from net losses driven by fair value declines in PMT’s taxable subsidiary.

Executive Chairman Stanford L. Kurland concluded, “PMT’s partnership with PFSI and exclusive access to unique investments in GSE CRT and MSRs from its own conventional correspondent production have delivered strong results, placing PMT among the top performing residential mortgage REIT stocks in 2018.  We remain focused on prudently growing PMT’s core investments in CRT and MSRs while continuing to seek attractive new opportunities in the dynamic U.S. mortgage market.  The recent launch of HELOC and prime non-QM loan products by our manager and service provider, PennyMac Financial, is expected to leverage PMT’s ability to securitize and retain credit risk investments from securitizations while further diversifying its investment portfolio.”

Management’s slide presentation will be available in the Investor Relations section of the Company’s website at www.pennymac-REIT.com beginning at 1:30 p.m. (Pacific Standard Time) on Thursday, February 7, 2019.
