“PMT’s performance in the first quarter demonstrates the earnings potential of our organic investments in CRT and MSRs,” said President and CEO David Spector.  “CRT investments delivered strong performance during the quarter, resulting from investment growth and credit spread tightening that reversed valuation-related losses from the prior quarter.  Our sophisticated interest rate risk management strategies mitigated the impact of declining rates on the fair value of our MSR and excess servicing spread (ESS) investments. Furthermore, the decline in mortgage rates has improved the outlook for mortgage originations and the prospects for growth of CRT and MSR investments sourced from PMT’s correspondent production activities.  As a result of PMT’s scale and market position, we are optimistic regarding our prospects for growth.  In order to continue capturing the significant investment opportunities available to us, we raised approximately $147 million in new equity during the quarter and are deploying this capital into new investments at attractive returns.”

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 $58.4 million on revenues of $61.1 million, compared to pretax income of $17.9 million on revenues of $22.3 million in the prior quarter.

The Credit Sensitive Strategies segment recorded a net gain on mortgage loans acquired for sale of $11.1 million, a decrease from $14.0 million in the prior quarter. These amounts represent the recognition of the fair value of firm commitment to acquire CRT securities under a new REMIC structure; for the first quarter of 2019, an additional $8.6 million was attributed to the Correspondent Production segment.

Net gain on investments in the segment was $53.8 million, up 341 percent from the prior quarter.  

Net gain on CRT investments for the quarter was $53.1 million, compared to $9.8 million in the prior quarter, and included $20.4 million in valuation-related gains driven by credit spread tightening from improved market conditions, which reversed losses related to credit spread

widening in the prior quarter.  Net gain on CRT investments also included $33.6 million in realized gains and carry, up from $30.1 million in the prior quarter, and recognized losses of $0.9 million, up from $0.7 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 $0.5 million, down from $2.5 million in the prior quarter. Fair value gains on performing loans in the distressed portfolio were $0.4 million, while fair value gains on nonperforming loans were $0.5 million and realized losses related to payoffs and loan sales were $0.4 million.

Net interest expense for the segment totaled $3.8 million, compared to $2.5 million in the prior quarter.  Interest income totaled $8.3 million, a 19 percent decrease from the prior quarter, driven by a smaller distressed loan portfolio.  Interest expense totaled $12.0 million, down from $12.6 million in the prior quarter.

Other investment losses in the segment were $30,000, compared to losses of $1.4 million in the prior quarter, driven by the continued liquidation of the real estate acquired in the settlement of loans (REO) portfolio.  At quarter end, PMT’s inventory of REO properties totaled $72.2 million, down from $85.7 million at December 31, 2018.

Segment expenses were $2.7 million, down 38 percent from the prior quarter driven by elevated professional services expense in the prior quarter and a reduction in servicing expenses resulting from the ongoing liquidation of the distressed loan portfolio.

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 $0.8 million on revenues of $11.2 million, compared to pretax income of $20.1 million on revenues of $30.2 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 decreasing interest rates, MSRs and ESS typically decrease in fair value whereas Agency MBS typically increase 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 $41.3 million, and primarily consisted of $36.7 million of gains on MBS and $7.4 million of gains in the value of hedging derivatives, partially offset by a $3.6 million loss in the value of ESS investments.

Net mortgage loan servicing fees resulted in a loss of $31.1 million, compared to a loss of $7.5 million in the prior quarter.  Net mortgage loan servicing fees included $61.3 million in servicing fees and $3.2 million in ancillary and other fees, reduced by $40.8 million in realization of MSR cash flows.  Net mortgage loan servicing fees also included a $96.5 million decrease in the fair value of MSRs, $41.1 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.

MSR valuation losses were primarily driven by a decrease in mortgage rates during the quarter, resulting in expectations for higher prepayment activity in the future.  ESS investments also declined in value from a decrease in mortgage rates and the ongoing paydown of the underlying loans, partially offset by 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.

Net interest income for the segment was $1.0 million compared to $3.2 million in the prior quarter.  Interest income totaled $34.1 million, up from $32.9 million in the prior quarter primarily driven by a larger average MBS portfolio.  Interest expense totaled $33.1 million, up from $29.7 million in the prior quarter, driven by increased financing costs related to growth in MBS and MSR investments.

Segment expenses were $10.4 million, a 4 percent increase from the prior quarter, primarily driven by higher servicing fee expense on a growing MSR portfolio.

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 pretax income of $3.6 million, compared to a loss of $0.6 million in the prior quarter.  

Through its correspondent production activities, PMT acquired $15.1 billion in UPB of loans from nonaffiliates compared to $18.1 billion in the prior quarter.  Of total correspondent acquisitions, conventional conforming and jumbo acquisitions from nonaffiliates totaled $8.3 billion, and government-insured or guaranteed acquisitions totaled $6.8 billion, compared to $9.2 billion and $8.9 billion, respectively, in the prior quarter. PMT also acquired $0.7 billion of conventional loans from PennyMac Financial, compared to $0.9 billion in the prior quarter.

PMT issued interest rate lock commitments on conventional loans totaling $9.0 billion, compared to $9.7 billion in the prior quarter.

Segment revenues were $33.8 million, a 9 percent increase from the prior quarter and included a net gain on mortgage loans of $10.2 million, other income of $13.0 million, which primarily consists of volume-based origination fees, and net interest income of $10.7 million.  Net gain on mortgage loans acquired for sale in the quarter increased by $6.6 million from the prior quarter, driven by improved production margins and which includes CRT-related gains as discussed earlier. Net interest income decreased $1.6 million from the prior quarter, primarily driven by lower production volumes.  Net interest income includes the recognition of incentives the Company is entitled to receive under one of its master repurchase agreements to finance mortgage loans that satisfy certain consumer relief characteristics.  These incentives totaled $7.5 million, down from $8.7 million in the fourth quarter.  As previously noted, the Company expects to cease accruing incentives under this repurchase agreement in the second quarter of 2019. While there can be no assurance, the Company expects that the loss of any such incentives will be partially offset by an improvement in pricing margins.

Segment expenses were $30.2 million, down 4 percent from the prior quarter resulting from a decrease in production activity, partially offset by an increase in the weighted average fulfillment fee during the quarter.  The weighted average fulfillment fee rate in the first quarter was 34 basis points, up from 32 basis points in the prior quarter.

Corporate Segment

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

Segment revenues were $436,000, up from $417,000 in the prior quarter.

Management fees were $7.2 million, up 11 percent from the prior quarter driven by a combination of increased incentive fees paid to PFSI based on PMT’s profitability and an increase in PMT’s shareholders’ equity from the issuance of common shares during the quarter.

Other segment expenses were $6.1 million, up from $5.1 million in the prior quarter.

Taxes

PMT recorded a $3.7 million benefit for income tax expense compared to a $15.4 million benefit in the prior quarter, driven by fair value losses on investments held in PMT’s taxable subsidiary.

“The availability of opportunities in today’s mortgage market, combined with PMT’s access to the operational capabilities of PFSI to organically generate attractive investments, drives our optimistic outlook,” concluded Executive Chairman Stanford L. Kurland. “To facilitate our long-term growth and maximize returns, we continue to develop innovative ways to strengthen our balance sheet and reduce liquidity risk.  The groundbreaking CRT financing structure we launched this quarter began to provide term financing for our CRT investments through a cost-effective and capital-efficient structure.  The term notes we issued more effectively match the duration of our CRT assets and improves the return on equity of our CRT investments.  We now

have in place term financing solutions for both of PMT’s core investments – CRT and MSRs – which will help PMT support its growth trajectory and strong performance in the future.  As we pursue PMT’s growth strategy, we also expect to gain efficiencies as we leverage our corporate infrastructure across a larger asset base and realize greater economies of scale.”
