SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q (“Report”) contains certain forward-looking statements that are subject to various risks and uncertainties. Forward-looking statements are generally identifiable by use of forward-looking terminology such as “may,” “will,” “should,” “potential,” “intend,” “expect,” “seek,” “anticipate,” “estimate,” “approximately,” “believe,” “could,” “project,” “predict,” “continue,” “plan” or other similar words or expressions.

Forward-looking statements are based on certain assumptions, discuss future expectations, describe future plans and strategies, contain financial and operating projections or state other forward-looking information. Examples of forward-looking statements include the following:

• projections of our revenues, income, earnings per share, capital structure or other financial items;

• descriptions of our plans or objectives for future operations, products or services;

• forecasts of our future economic performance, interest rates, profit margins and our share of future markets; and

• descriptions of assumptions underlying or relating to any of the foregoing expectations regarding the timing of generating any revenues.

Our ability to predict results or the actual effect of future events, actions, plans or strategies is inherently uncertain. Although we believe that the expectations reflected in such forward-looking statements are based on reasonable assumptions, our actual results and performance could differ materially from those set forth in the forward-looking statements. There are a number of factors, many of which are beyond our control that could cause actual results to differ significantly from management’s expectations. Some of these factors are discussed below.

You should not place undue reliance on any forward-looking statement and should consider the following uncertainties and risks, as well as the risks and uncertainties discussed elsewhere in this Report and the section entitled “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2016, filed with the Securities and Exchange Commission (“SEC”) on February 28, 2017.

Factors that could cause actual results to differ materially from historical results or those anticipated include, but are not limited to:

• changes in our investment objectives or investment or operational strategies, including any new lines of business or new products and services that may subject us to additional risks;

• volatility in our industry, the debt or equity markets, the general economy or the real estate finance and real estate markets specifically, whether the result of market events or otherwise;

• events or circumstances which undermine confidence in the financial markets or otherwise have a broad impact on financial markets, such as the sudden instability or collapse of large depository institutions or other significant corporations, terrorist attacks, natural or man-made disasters, or threatened or actual armed conflicts;

• changes in general business, economic, market, employment and political conditions, or in consumer confidence and spending habits from those expected;

• declines in real estate or significant changes in U.S. housing prices or activity in the U.S. housing market;

• the availability of, and level of competition for, attractive risk-adjusted investment opportunities in mortgage loans and mortgage-related assets that satisfy our investment objectives;

• the inherent difficulty in winning bids to acquire mortgage loans, and our success in doing so;

• the concentration of credit risks to which we are exposed;

• the degree and nature of our competition;

• our dependence on our manager and servicer, potential conflicts of interest with such entities and their affiliates, and the performance of such entities;

• changes in personnel and lack of availability of qualified personnel at our manager, servicer or their affiliates;

• the availability, terms and deployment of short-term and long-term capital;

• the adequacy of our cash reserves and working capital;

1

• our ability to maintain the desired relationship between our financing and the interest rates and maturities of our assets;

• the timing and amount of cash flows, if any, from our investments;

• unanticipated increases or volatility in financing and other costs, including a rise in interest rates;

• the performance, financial condition and liquidity of borrowers;

• the ability of our servicer, which also provides us with fulfillment services, to approve and monitor correspondent sellers and underwrite loans to investor standards;

• incomplete or inaccurate information or documentation provided by customers or counterparties, or adverse changes in the financial condition of our customers and counterparties;

• our indemnification and repurchase obligations in connection with mortgage loans we purchase and later sell or securitize;

• the quality and enforceability of the collateral documentation evidencing our ownership and rights in the assets in which we invest;

• increased rates of delinquency, default and/or decreased recovery rates on our investments;

• the performance of mortgage loans underlying mortgage-backed securities (“MBS”) in which we retain credit risk;

• our ability to foreclose on our investments in a timely manner or at all;

• increased prepayments of the mortgages and other loans underlying our MBS or relating to our mortgage servicing rights (“MSRs”), excess servicing spread (“ESS”) and other investments;

• the degree to which our hedging strategies may or may not protect us from interest rate volatility;

• the effect of the accuracy of or changes in the estimates we make about uncertainties, contingencies and asset and liability valuations when measuring and reporting upon our financial condition and results of operations;

• our failure to maintain appropriate internal controls over financial reporting;

• technologies for loans and our ability to mitigate security risks and cyber intrusions;

• our ability to obtain and/or maintain licenses and other approvals in those jurisdictions where required to conduct our business;

• our ability to detect misconduct and fraud;

• our ability to comply with various federal, state and local laws and regulations that govern our business;

• developments in the secondary markets for our mortgage loan products;

• legislative and regulatory changes that impact the mortgage loan industry or housing market;

• changes in regulations or the occurrence of other events that impact the business, operations or prospects of government agencies such as the Government National Mortgage Association (“Ginnie Mae”), the Federal Housing Administration (the “FHA”) or the Veterans Administration (the “VA”), the U.S. Department of Agriculture (“USDA”), or government-sponsored entities such as the Federal National Mortgage Association (“Fannie Mae”) or the Federal Home Loan Mortgage Corporation (“Freddie Mac”) (Fannie Mae, Freddie Mac and Ginnie Mae are each referred to as an “Agency” and, collectively, as the “Agencies”), or such changes that increase the cost of doing business with such entities;

• the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) and its implementing regulations and regulatory agencies, and any other legislative and regulatory changes that impact the business, operations or governance of mortgage lenders and/or publicly-traded companies;

• the Consumer Financial Protection Bureau (“CFPB”) and its issued and future rules and the enforcement thereof;

• changes in government support of homeownership;

• changes in government or government-sponsored home affordability programs;

• limitations imposed on our business and our ability to satisfy complex rules for us to qualify as a real estate investment trust (“REIT”) for U.S. federal income tax purposes and qualify for an exclusion from the Investment Company Act of 1940 (the “Investment Company Act”) and the ability of certain of our subsidiaries to qualify as REITs or as taxable REIT subsidiaries (“TRSs”) for U.S. federal income tax purposes, as applicable, and our ability and the ability of our subsidiaries to operate effectively within the limitations imposed by these rules;

2

• changes in governmental regulations, accounting treatment, tax rates and similar matters (including changes to laws governing the taxation of REITs, or the exclusions from registration as an investment company);

• our ability to make distributions to our shareholders in the future;

• the effect of public opinion on our reputation;

• the occurrence of natural disasters or other events or circumstances that could impact our operations; and

• our organizational structure and certain requirements in our charter documents.

Other factors that could also cause results to differ from our expectations may not be described in this Report or any other document. Each of these factors could by itself, or together with one or more other factors, adversely affect our business, results of operations and/or financial condition.

Forward-looking statements speak only as of the date they are made, and we undertake no obligation to update any forward-looking statement to reflect the impact of circumstances or events that arise after the date the forward-looking statement was made.

PENNYMAC MORTGAGE INVESTMENT TRUST AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Note 1—Organization and Basis of Presentation

PennyMac Mortgage Investment Trust (“PMT” or the “Company”) was organized in Maryland on May 18, 2009, and commenced operations on August 4, 2009, when it completed its initial offerings of common shares of beneficial interest (“common shares”). The Company is a specialty finance company, which, through its subsidiaries (all of which are wholly-owned), invests primarily in residential mortgage-related assets.

The Company operates in four segments: correspondent production, credit sensitive strategies, interest rate sensitive strategies and corporate:

• The correspondent production segment represents the Company’s operations aimed at serving as an intermediary between mortgage lenders and the capital markets by purchasing, pooling and reselling newly originated prime credit quality mortgage loans either directly or in the form of mortgage-backed securities (“MBS”), using the services of PNMAC Capital Management, LLC (“PCM” or the “Manager”) and PennyMac Loan Services, LLC (“PLS”), both indirect controlled subsidiaries of PennyMac Financial Services, Inc. (“PFSI”).

Most of the mortgage loans the Company has acquired in its correspondent production activities have been eligible for sale to government-sponsored entities such as the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”) or through government agencies such as the Government National Mortgage Association (“Ginnie Mae”). Fannie Mae, Freddie Mac and Ginnie Mae are each referred to as an “Agency” and, collectively, as the “Agencies.”

• The credit sensitive strategies segment represents the Company’s investments in distressed mortgage loans, real estate acquired in settlement of mortgage loans (“REO”), credit risk transfer agreements (“CRT Agreements”), non-Agency subordinated bonds and small balance commercial real estate mortgage loans.

• The interest rate sensitive strategies segment represents the Company’s investments in mortgage servicing rights (“MSRs”), excess servicing spread (“ESS”), Agency and senior non-Agency MBS and the related interest rate hedging activities.  

• The corporate segment includes certain interest income, management fee and corporate expense amounts.

The Company believes that it qualifies, and has elected to be taxed, as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended, beginning with its taxable period ended on December 31, 2009. To maintain its tax status as a REIT, the Company has to distribute at least 90% of its taxable income in the form of qualifying distributions to shareholders.

The Company conducts substantially all of its operations and makes substantially all of its investments through its subsidiary, PennyMac Operating Partnership, L.P. (the “Operating Partnership”), and the Operating Partnership’s subsidiaries. A wholly-owned subsidiary of the Company is the sole general partner, and the Company is the sole limited partner, of the Operating Partnership.

The accompanying consolidated financial statements have been prepared in compliance with accounting principles generally accepted in the United States (“GAAP”) as codified in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) for interim financial information and with the Securities and Exchange Commission’s instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, these financial statements and notes do not include all of the information required by GAAP for complete financial statements. The interim consolidated information should be read together with the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

The accompanying unaudited consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, but are not necessarily indicative of the results of operations that may be anticipated for the full year. Intercompany accounts and transactions have been eliminated.

Preparation of financial statements in compliance with GAAP requires the Manager to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the reporting period. Actual results will likely differ from those estimates.

Note 2—Concentration of Risks

As discussed in Note 1— Organization and Basis of Presentation above, PMT’s operations and investing activities are centered in residential mortgage-related assets, a substantial portion of which were distressed at acquisition. The mortgage loans at fair value not acquired for sale or held in a variable interest entity (“VIE”) are generally purchased at discounts reflecting their distressed state or perceived higher risk of default, as well as a greater likelihood of collateral documentation deficiencies.

Due to the nature of the Company’s investments, PMT is exposed, to a greater extent than traditional mortgage investors, to the risks associated with loan resolution, including that borrowers may be in economic distress and/or may have become unemployed, bankrupt or otherwise unable or unwilling to make payments when due, and that fluctuations in the residential real estate market may affect the performance of its investments. Factors influencing these risks include, but are not limited to:

• changes in the overall economy, unemployment rates and residential real estate values in the markets where the properties securing the Company’s mortgage loans are located;

• PCM’s ability to identify and PLS’ ability to execute optimal resolutions of certain mortgage loans;

• the accuracy of valuation information obtained during the Company’s due diligence activities;

• PCM’s ability to effectively model, and to develop appropriate model inputs that properly anticipate, future outcomes;

• the level of government support for resolution of certain mortgage loans and the effect of current and future proposed and enacted legislative and regulatory changes on the Company’s ability to effect cures or resolutions to distressed mortgage loans; and

• regulatory, judicial and legislative support of the foreclosure process, and the resulting effect on the Company’s ability to acquire and liquidate the real estate securing its portfolio of distressed mortgage loans in a timely manner or at all.

Due to these uncertainties, there can be no assurance that risk management activities identified and executed on PMT’s behalf will prevent significant losses arising from the Company’s investments in real estate-related assets.

A substantial portion of the distressed mortgage loans and REO has been acquired by the Company in prior years from or through one or more subsidiaries of Citigroup Inc. and JPMorgan Chase & Co., as presented in the following summary:

Operating Activities

Correspondent Production Activities

The Company is provided fulfillment and other services by PLS under a mortgage banking services agreement. The Company’s mortgage banking services agreement provides for a fulfillment fee paid to PLS based on the type of mortgage loan that the Company acquires. The fulfillment fee is equal to a percentage of the unpaid principal balance of mortgage loans purchased by the Company. PLS has also agreed to provide such services exclusively for the Company’s benefit, and PLS and its affiliates are prohibited from providing such services for any other party.

11

Before September 12, 2016, the applicable fulfillment fee percentages were (i) 0.50% for conventional mortgage loans, (ii) 0.88% for loans sold in accordance with the Ginnie Mae Mortgage-Backed Securities Guide, and (iii) 0.50% for all other mortgage loans not contemplated above; provided, however, that PLS was permitted, in its sole discretion, to reduce the amount of the applicable fulfillment fee and credit the amount of such reduction to any reimbursement that would have otherwise been due based on volumes tied to the aggregate unpaid principal balance of the mortgage loans purchased by the Company in the related month. This reduction was only credited to the reimbursement applicable to the month in which the related mortgage was funded.

Effective as of September 12, 2016, pursuant to the terms of an amended and restated mortgage banking services agreement the applicable fulfillment fee percentages are (i) 0.35% for mortgage loans sold or delivered to Fannie Mae or Freddie Mac, and (ii) 0.85% for all other mortgage loans; provided however, that no fulfillment fee shall be due or payable to PLS with respect to any mortgage loans underwritten to Ginnie Mae guidelines. The Company does not hold the Ginnie Mae approval required to issue securities guaranteed by Ginnie Mae MBS and act as a servicer. Accordingly, under the agreement, PLS currently purchases loans salable in accordance with the Ginnie Mae Mortgage-Backed Securities Guide “as is” and without recourse of any kind from the Company at cost less any administrative fees paid by the Correspondent to PMT plus accrued interest and a sourcing fee ranging from two to three and one-half basis points, generally based on the average number of calendar days loans are held by the Company prior to purchase by PLS. The discretionary reductions and volume reimbursements described above are no longer in effect.

In consideration for the mortgage banking services provided by PLS with respect to the Company’s acquisition of mortgage loans under PLS’s early purchase program, PLS is entitled to fees accruing (i) at a rate equal to $1,500 per annum per early purchase facility, and (ii) in the amount of $35 for each mortgage loan that the Company acquires.

The mortgage banking services agreement expires on September 12, 2020, subject to automatic renewal for additional 18-month periods, unless terminated earlier in accordance with the terms of the agreement.

Mortgage Loan Servicing Activities

The Company, through its Operating Partnership, has a mortgage loan servicing agreement with PLS. The servicing agreement provides for servicing fees earned by PLS that are based on a percentage of the mortgage loan’s unpaid principal balance or fixed per loan monthly amounts based on the delinquency, bankruptcy and/or foreclosure status of the serviced mortgage loan or the REO. PLS is also entitled to market-based fees and charges including boarding and deboarding fees, liquidation and disposition, assumption, modification and origination fees and late charges relating to mortgage loans it services for the Company. The servicing agreement was amended and restated as of September 12, 2016; however, the fee structure was not amended in any material respect.

• The base servicing fees for distressed mortgage loans are calculated based on a monthly per-loan dollar amount, with the actual dollar amount for each mortgage loan based on the delinquency, bankruptcy and/or foreclosure status of such mortgage loan or the related underlying real estate. Presently, the base servicing fees for distressed mortgage loans range from $30 per month for current mortgage loans up to $100 per month for mortgage loans where the borrower has declared bankruptcy. PLS is also entitled to certain activity-based fees for distressed mortgage loans that are charged based on the achievement of certain events. These fees range from 0.50% for a streamline modification to 1.50% for a liquidation and $500 for a deed-in-lieu of foreclosure. PLS is not entitled to earn more than one liquidation fee, reperformance fee or modification fee in any 18-month period.

• The base servicing fee rate for REO is $75 per month. To the extent that the Company rents its REO under an REO rental program, the Company pays PLS an REO rental fee of $30 per month per REO, an REO property lease renewal fee of $100 per lease renewal, and a property management fee in an amount equal to PLS’ cost if property management services and/or any related software costs are outsourced to a third-party property management firm or 9% of gross rental income if PLS provides property management services directly. PLS is also entitled to retain any tenant paid application fees and late rent fees and seek reimbursement for certain third party vendor fees.

• The base servicing fees for non-distressed mortgage loans subserviced by PLS on the Company’s behalf are also calculated through a monthly per-loan dollar amount, with the actual dollar amount for each loan based on whether the mortgage loan is a fixed-rate or adjustable-rate loan. The base servicing fees for loans subserviced on the Company’s behalf are $7.50 per month for fixed-rate loans and $8.50 per month for adjustable-rate mortgage loans.

• To the extent that these non-distressed mortgage loans become delinquent, PLS is entitled to an additional servicing fee per mortgage loan ranging from $10 to $55 per month and based on the delinquency, bankruptcy and foreclosure status of the mortgage loan or $75 per month if the underlying mortgaged property becomes REO. PLS is also entitled to customary ancillary income and certain market-based fees and charges, including boarding and deboarding fees, liquidation and disposition fees, assumption, modification and origination fees.

• PLS is required to provide a range of services and activities significantly greater in scope than the services provided in connection with a customary servicing arrangement because the Company does not have any employees or infrastructure. For these services, PLS received a supplemental fee of $25 per month for each distressed whole loan. PLS is entitled to reimbursement for all customary, good faith reasonable and necessary out-of-pocket expenses incurred in performance of its servicing obligations.

• PLS, on behalf of the Company, is entitled to retain any incentive payments made to it and to which it is entitled under the U.S. Department of Treasury’s Home Affordable Modification Plan (“HAMP”); provided, however, that with respect to any such incentive payments paid to PLS under HAMP in connection with a mortgage loan modification for which the Company previously paid PLS a modification fee, PLS shall reimburse the Company an amount equal to the incentive payments.

The term of the servicing agreement, as amended, expires on September 12, 2020, subject to automatic renewal for additional 18-month periods, unless terminated earlier in accordance with the terms of the servicing agreement.

Pursuant to the terms of an MSR recapture agreement, if PLS refinances through its consumer direct lending business mortgage loans for which the Company previously held the MSRs, PLS is generally required to transfer and convey to one of the Company’s wholly-owned subsidiaries without cost to the Company, the MSRs with respect to new mortgage loans originated in those refinancings (or, under certain circumstances, other mortgage loans) that have an aggregate unpaid principal balance that is not less than 30% of the aggregate unpaid principal balance of all the loans so originated. Where the fair value of the aggregate MSRs to be transferred for the applicable month is less than $200,000, PLS may, at its option, pay cash to the Company in an amount equal to such fair value instead of transferring such MSRs.

The MSR recapture agreement was amended and restated as of September 12, 2016; however, the fee structure was not amended in any material respect. The MSR recapture agreement expires, unless terminated earlier in accordance with the agreement, on September 12, 2020, subject to automatic renewal for additional 18-month periods.

Management Fees

Under a management agreement, the Company pays PCM management fees as follows:

• A base management fee that is calculated quarterly and is equal to the sum of (i) 1.5% per year of average shareholders’ equity up to $2 billion, (ii) 1.375% per year of average shareholders’ equity in excess of $2 billion and up to $5 billion, and (iii) 1.25% per year of average shareholders’ equity in excess of $5 billion.

• A performance incentive fee that is calculated at a defined annualized percentage of the amount by which “net income,” on a rolling four-quarter basis and before deducting the incentive fee, exceeds certain levels of return on “equity.”

The performance incentive fee is calculated quarterly and is equal to: (a) 10% of the amount by which net income for the quarter exceeds (i) an 8% return on equity plus the high watermark, up to (ii) a 12% return on equity; plus (b) 15% of the amount by which net income for the quarter exceeds (i) a 12% return on equity plus the high watermark, up to (ii) a 16% return on equity; plus (c) 20% of the amount by which net income for the quarter exceeds a 16% return on equity plus the high watermark.

For the purpose of determining the amount of the performance incentive fee:

“Net income” is defined as net income or loss computed in accordance with GAAP and certain other non-cash charges determined after discussions between PCM and PMT’s independent trustees and after approval by a majority of PMT’s independent trustees.

“Equity” is the weighted average of the issue price per common share of all of PMT’s public offerings, multiplied by the weighted average number of common shares outstanding (including restricted share units) in the rolling four-quarter period.

14

The “high watermark” is the quarterly adjustment that reflects the amount by which the net income (stated as a percentage of return on equity) in that quarter exceeds or falls short of the lesser of 8% and the Fannie Mae MBS yield (the target yield) for such quarter. The “high watermark” starts at zero and is adjusted quarterly. If the net income is lower than the target yield, the high watermark is increased by the difference. If the net income is higher than the target yield, the high watermark is reduced by the difference. Each time a performance incentive fee is earned, the high watermark returns to zero. As a result, the threshold amounts required for PCM to earn a performance incentive fee are adjusted cumulatively based on the performance of PMT’s net income over (or under) the target yield, until the net income in excess of the target yield exceeds the then-current cumulative high watermark amount, and a performance incentive fee is earned.

The base management fee and the performance incentive fee are both payable quarterly in arrears. The performance incentive fee may be paid in cash or a combination of cash and PMT’s common shares (subject to a limit of no more than 50% paid in common shares), at the Company’s option.

The management agreement was amended and restated as of September 12, 2016; however, the fee structure was not amended in any material respect. Following is a summary of the base management and performance incentive fees payable to PCM recorded by the Company:

	Quarter ended March 31,

	(in thousands)
Base management	$	5,008	$	5,352
Performance incentive		—		—
	$	5,008	$	5,352

In the event of termination of the management agreement between the Company and PFSI, PFSI may be entitled to a termination fee in certain circumstances. The termination fee is equal to three times the sum of (a) the average annual base management fee, and (b) the average annual performance incentive fee earned by PFSI, in each case during the 24-month period before termination.

Expense Reimbursement and Amounts Payable to and Receivable from PFSI

Under the management agreement, PCM is entitled to reimbursement of its organizational and operating expenses, including third-party expenses, incurred on the Company’s behalf, it being understood that PCM and its affiliates shall allocate a portion of their personnel’s time to provide certain legal, tax and investor relations services for the direct benefit of the Company. With respect to the allocation of PCM’s and its affiliates personnel, from and after September 12, 2016, PCM shall be reimbursed $120,000 per fiscal quarter, such amount to be reviewed annually and to not preclude reimbursement for any other services performed by PCM or its affiliates.

The Company is required to pay PCM and its affiliates a pro rata portion of rent, telephone, utilities, office furniture, equipment, machinery and other office, internal and overhead expenses of PCM and its affiliates required for the Company’s and its subsidiaries’ operations. These expenses will be allocated based on the ratio of the Company’s and its subsidiaries’ proportion of gross assets compared to all remaining gross assets managed by PCM as calculated at each fiscal quarter end:

Investing Activities

On February 29, 2016, the Company and PLS terminated that certain master spread acquisition and MSR servicing agreement that the parties entered into effective February 1, 2013 (the “2/1/13 Spread Acquisition Agreement”) and all amendments thereto. In connection with the termination of the 2/1/13 Spread Acquisition Agreement, PLS reacquired from the Company all of its right, title and interest in and to all of the Fannie Mae ESS previously sold by PLS to the Company under the 2/1/13 Spread Acquisition Agreement and then subject to such 2/1/13 Spread Acquisition Agreement. On February 29, 2016, PLS also reacquired from the Company all of its right, title and interest in and to all of the Freddie Mac ESS previously sold to the Company by PLS. The amount of ESS sold by the Company to PLS under these reacquisitions was $59.0 million.

Repurchase Agreement with PLS

On December 19, 2016, the Company, through a wholly-owned subsidiary, PennyMac Holdings, LLC (“PMH”), entered into a master repurchase agreement with PLS (the “PMH Repurchase Agreement”), pursuant to which PMH may borrow from PLS for the purpose of financing PMH’s participation certificates representing beneficial ownership in ESS. PLS then re-pledges such participation certificates to PNMAC GMSR ISSUER TRUST (the “Issuer Trust”) under a master repurchase agreement by and among PLS, the Issuer Trust and Private National Mortgage Acceptance Company, LLC, as guarantor (the “PC Repurchase Agreement”). The Issuer Trust was formed for the purpose of allowing PLS to finance MSRs and ESS relating to such MSRs (the “GNMA MSR Facility”).

In connection with the GNMA MSR Facility, PLS pledges and/or sells to the Issuer Trust participation certificates representing beneficial interests in MSRs and ESS pursuant to the terms of the PC Repurchase Agreement. In return, the Issuer Trust (a) has issued to PLS, pursuant to the terms of an indenture, the Series 2016-MSRVF1 Variable Funding Note, dated December 19, 2016, known as the “PNMAC GMSR ISSUER TRUST MSR Collateralized Notes, Series 2016-MSRVF1” (the “VFN”), and (b) may, from time to time pursuant to the terms of any supplemental indenture, issue to institutional investors additional term notes (“Term Notes”), in each case secured on a pari passu basis by the participation certificates relating to the MSRs and ESS. The maximum principal balance of the VFN is $1,000,000,000.

The principal amount paid by PLS for the participation certificates under the PMH Repurchase Agreement is based upon a percentage of the market value of the underlying ESS. Upon PMH’s repurchase of the participation certificates, PMH is required to repay PLS the principal amount relating thereto plus accrued interest (at a rate reflective of the current market and consistent with the weighted average note rate of the VFN and any outstanding Term Notes) to the date of such repurchase. PLS is then required to repay the Issuer Trust the corresponding amount under the PC Repurchase Agreement.

Note Payable to PLS

Before entering into the PMH Repurchase Agreement, PLS was a party to a repurchase agreement between it and Credit Suisse First Boston Mortgage Capital LLC (“CSFB”) (the “MSR Repo”), pursuant to which PLS financed Ginnie Mae MSRs and servicing advance receivables and pledged all of its rights and interests in any Ginnie Mae MSRs it owned to CSFB, and a separate acknowledgement agreement with respect thereto, by and among Ginnie Mae, CSFB and PLS. In connection with the MSR Repo, the Company was party to an underlying loan and security agreement with PLS, pursuant to which the Company was able to borrow up to $150 million from PLS for the purpose of financing its investment in ESS (the “Underlying LSA”). The principal amount of the borrowings under the Underlying LSA was based upon a percentage of the market value of the ESS pledged to PLS, subject to the $150 million sublimit described above. Pursuant to the Underlying LSA, the Company granted to PLS a security interest in all of its right, title and interest in, to and under the ESS pledged to secure the borrowings, and PLS, in turn, re-pledged such ESS to CSFB under the MSR Repo. Interest accrued on the Company’s note relating to the Underlying LSA at a rate based on CSFB’s cost of funds under the MSR Repo. The underlying LSA was terminated in connection with the execution of the PMH Agreement.

Conditional Reimbursement of Initial Public Offering (“IPO”) Underwriting Fees

In connection with its IPO, the Company conditionally agreed to reimburse PCM up to $2.9 million for underwriting fees paid to the IPO underwriters by PCM on the Company’s behalf (the “Conditional Reimbursement”). Also in connection with its IPO, the Company agreed to pay the IPO underwriters up to $5.9 million in contingent underwriting fees.

Note 4—Earnings Per Share

The Company grants restricted share units which entitle the recipients to receive dividend equivalents during the vesting period on a basis equivalent to the dividends paid to holders of common shares. Unvested share-based compensation awards containing non-forfeitable rights to receive dividends or dividend equivalents (collectively, “dividends”) are classified as “participating securities” and are included in the basic earnings per share calculation using the two-class method.

Under the two-class method, all earnings (distributed and undistributed) are allocated to common shares and participating securities, based on their respective rights to receive dividends. Basic earnings per share is determined by dividing net income, reduced by income attributable to the participating securities, by the weighted-average common shares outstanding during the period.

Diluted earnings per share is determined by dividing net income attributable to diluted shareholders, which adds back to net income the interest expense, net of applicable income taxes, on the Company’s exchangeable senior notes (the “Exchangeable Notes”), by the weighted-average common shares outstanding, assuming all dilutive securities were issued. In periods in which the Company records a loss, potentially dilutive securities are excluded from the diluted loss per share calculation, as their effect on loss per share is anti-dilutive.

The following table summarizes the basic and diluted earnings per share calculations:

	Quarter ended March 31,

Note 5—Loan Sales and Variable Interest Entities

The Company is a variable interest holder in various special purpose entities that relate to its mortgage loan transfer and financing activities. These entities are classified as VIEs for accounting purposes. The Company has segregated its involvement with VIEs between those VIEs which the Company does not consolidate and those VIEs which the Company consolidates.

Credit Risk Transfer Agreements

The Company, through its wholly-owned subsidiary, PennyMac Corp. (“PMC”), entered into CRT Agreements with Fannie Mae, pursuant to which PMC, through subsidiary trust entities, sells pools of mortgage loans into Fannie Mae-guaranteed securitizations while retaining a portion of the credit risk underlying such mortgage loans (“Recourse Obligations”) as part of the retention of an interest-only ownership interest in such mortgage loans.  The mortgage loans subject to the CRT Agreements are transferred by PMC to subsidiary trust entities which sell the mortgage loans into Fannie Mae mortgage loan securitizations. Transfers of mortgage loans subject to CRT Agreements receive sale accounting treatment upon fulfillment of the criteria for sale recognition contained in the Transfers and Servicing topic of the ASC. The pledged cash represents the Company’s maximum contractual exposure to claims under its Recourse Obligations and is the sole source of settlement of losses under the CRT Agreements. Gains and losses on net derivatives related to CRT Agreements are included in Net gain on investments in the consolidated statements of income.

Jumbo Mortgage Loan Financing

On September 30, 2013, the Company completed a securitization transaction in which PMT Loan Trust 2013-J1, a VIE, issued $537.0 million in UPB of certificates backed by fixed-rate prime jumbo mortgage loans, at a 3.9% weighted yield. The Company initially retained $366.8 million in fair value of such certificates. During the quarter ended March 31, 2016 the Company sold $100.6 million in UPB of those certificates, which reduced the fair value of the certificates retained by the Company to $9.1 million as of March 31, 2017. The Company included the proceeds from the sales in Asset backed financing of a variable interest entity at fair value. The Company issued no certificates during the quarter ended March 31, 2017.

Note 6—Netting of Financial Instruments

The Company uses derivative financial instruments to manage exposure to interest rate risk created by its MBS, interest rate lock commitments (“IRLCs”), mortgage loans acquired for sale at fair value, mortgage loans at fair value held in a VIE, ESS and MSRs. All derivative financial instruments are recorded on the consolidated balance sheets at fair value. The Company has elected to net derivative asset and liability positions, and cash collateral obtained from (or posted to) its counterparties when subject to a legally enforceable master netting arrangement. The derivative financial instruments that are not subject to master netting arrangements are IRLCs and the derivatives related to CRT Agreements. As of March 31, 2017 and December 31, 2016, the Company did not enter into reverse repurchase agreements or securities lending transactions that are required to be disclosed in the following tables.

Note 7—Fair Value

The Company’s consolidated financial statements include assets and liabilities that are measured based on their fair values. Measurement at fair value may be on a recurring or nonrecurring basis depending on the accounting principles applicable to the specific asset or liability and whether the Manager has elected to carry the item at its fair value as discussed in the following paragraphs.

The Company groups its assets and liabilities at fair value in three levels, based on the markets in which the assets and liabilities are traded and the observability of the inputs used to determine fair value. These levels are:

• Level 1—Quoted prices in active markets for identical assets or liabilities.

• Level 2—Prices determined or determinable using other significant observable inputs. Observable inputs are inputs that other market participants would use in pricing the asset or liability and are developed based on market data obtained from sources independent of the Company. These may include quoted prices for similar assets or liabilities, interest rates, prepayment speeds, credit risk and other inputs.

• Level 3—Prices determined using significant unobservable inputs. In situations where significant observable inputs are unavailable unobservable inputs may be used. Unobservable inputs reflect the Company’s own judgments about the factors that market participants use in pricing assets and liabilities, and are based on the best information available in the circumstances.

As a result of the difficulty in observing certain significant valuation inputs affecting “Level 3” fair value assets and liabilities, the Manager is required to make judgments regarding these items’ fair values. Different persons in possession of the same facts may reasonably arrive at different conclusions as to the inputs to be applied in valuing these assets and liabilities and to their fair values. Likewise, due to the general illiquidity of some of these assets and liabilities, subsequent transactions may be at values significantly different from those reported.

23

Fair Value Accounting Elections

The Manager identified all of the Company’s non-cash financial assets and MSRs relating to non-commercial real estate secured mortgage loans with initial interest rates of more than 4.5%, to be accounted for at fair value. The Manager has elected to account for these assets at fair value so such changes in fair value will be reflected in income as they occur and more timely reflect the results of the Company’s performance.

The Manager has also identified the Company’s asset-backed financing of a VIE and interest only security payable at fair value to be accounted for at fair value to reflect the generally offsetting changes in fair value of these borrowings to changes in fair value of mortgage loans at fair value or other assets collateralizing these financings. For other borrowings, the Manager has determined that historical cost accounting is more appropriate because under this method debt issuance costs are amortized over the term of the debt, thereby matching the debt issuance cost to the periods benefiting from the availability of the debt.

Real Estate Acquired in Settlement of Loans

The Company evaluates its REO for impairment with reference to the respective properties’ fair values less cost to sell on a nonrecurring basis. The initial carrying value of the REO is measured at cost as indicated by the purchase price in the case of purchased REO or as measured by the fair value of the mortgage loan immediately before REO acquisition in the case of acquisition in settlement of a loan. REO may be subsequently revalued due to the Company receiving greater access to the property, the property being held for an extended period or receiving indications that the property’s value may not be supported by developing market conditions. Any subsequent change in fair value to a level that is less than or equal to the property’s cost is recognized in Results of real estate acquired in settlement of loans in the Company’s consolidated statements of income.

29

Mortgage Servicing Rights at Lower of Amortized Cost or Fair Value

The Company evaluates its MSRs at lower of amortized cost or fair value for impairment with reference to the asset’s fair value. For purposes of performing its MSR impairment evaluation, the Company stratifies its MSRs at lower of amortized cost or fair value based on the interest rates borne by the mortgage loans underlying the MSRs. Mortgage loans are grouped into pools with 50 basis point interest rate ranges for fixed-rate mortgage loans with interest rates between 3.0% and 4.5% and a single pool for mortgage loans with interest rates below 3.0%. MSRs relating to adjustable rate mortgage loans with initial interest rates of 4.5% or less are evaluated in a single pool. If the fair value of MSRs in any of the interest rate pools is below the amortized cost of the MSRs, those MSRs are impaired.

When MSRs are impaired, the impairment is recognized in current-period income and the carrying value of the MSRs is adjusted using a valuation allowance. If the fair value of the MSRs subsequently increases, the increase in fair value is recognized in current period income only to the extent of the valuation allowance for the respective impairment stratum.

The Manager periodically reviews the various impairment strata to determine whether the fair value of the impaired MSRs in a given stratum is likely to recover. When the Manager deems recovery of fair value to be unlikely in the foreseeable future, a write-down of the cost of the MSRs for that stratum to its estimated recoverable value is charged to the valuation allowance.

Fair Value of Financial Instruments Carried at Amortized Cost

Certain of the Company’s borrowings are carried at amortized cost. The Company’s Assets sold under agreements to repurchase, Mortgage loan participation and sale agreements, Notes payable, Exchangeable senior notes, Assets sold to PennyMac Financial Services, Inc. under agreements to repurchase and Federal Home Loan Bank advances are classified as “Level 3” fair value assets and liabilities due to the Company’s reliance on unobservable inputs to estimate these instruments’ fair values.

The Manager has concluded that the fair values of Assets sold under agreements to repurchase, Mortgage loan participation and sale agreements, and Notes payable approximate the agreements’ carrying values due to the borrowing agreements’ short terms and variable interest rates. The fair value of the Exchangeable senior notes at March 31, 2017 and December 31, 2016 was $244.0 million and $240.7 million, respectively. The fair value of the Exchangeable senior notes is estimated using a broker indication of  fair value.

Valuation Techniques and Inputs

Most of the Company’s assets, its Derivative liabilities, the Asset-backed financing of a VIE and the Interest-only security payable are carried at fair value with changes in fair value recognized in current period income. A substantial portion of these items are “Level 3” fair value assets and liabilities which require the use of unobservable inputs that are significant to the estimation of the assets and liabilities’ fair values. Unobservable inputs reflect the Company’s own judgments about the factors that market participants use in pricing an asset or liability, and are based on the best information available under the circumstances.

Due to the difficulty in estimating the fair values of “Level 3” fair value assets and liabilities, the Manager has assigned responsibility for estimating fair value of these assets and liabilities to specialized staff and subjects the valuation process to significant executive management oversight. The Manager’s Financial Analysis and Valuation group (the “FAV group”) is responsible for estimating the fair values of “Level 3” fair value assets and liabilities other than IRLCs and maintaining its valuation policies and procedures.

With respect to the Company’s non-IRLC “Level 3” fair value assets and liabilities, the FAV group reports to PCM’s valuation committee, which oversees and approves the valuations. The FAV group monitors the models used for valuation of the Company’s non-IRLC “Level 3” fair value assets and liabilities, including the models’ performance versus actual results, and reports those results to PCM’s valuation committee. PCM’s valuation committee includes PFSI’s executive chairman and chief executive, chief financial, chief enterprise operations, chief risk and deputy chief financial officers.

The FAV group is responsible for reporting to PCM’s valuation committee on a monthly basis on the changes in the valuation of the non-IRLC “Level 3” assets and liabilities, including major factors affecting the valuation and any changes in model methods and inputs. To assess the reasonableness of its valuations, the FAV group presents an analysis of the effect on the valuation of changes to the significant inputs to the models.

The fair value of the Company’s IRLCs is developed by the Manager’s Capital Markets Risk Management staff and is reviewed by the Manager’s Capital Markets Operations group.

30

The following is a description of the techniques and inputs used in estimating the fair values of “Level 2” and “Level 3” fair value assets and liabilities:

Mortgage-Backed Securities

The Company categorizes its current holdings of MBS as “Level 2” fair value assets. Fair value of these MBS is established based on quoted market prices for the Company’s MBS or similar securities. Changes in the fair value of MBS are included in Net gain (loss) on investments in the consolidated statements of income.

Mortgage Loans

Fair value of mortgage loans is estimated based on whether the mortgage loans are saleable into active markets:

• Mortgage loans that are saleable into active markets, comprised of the Company’s mortgage loans acquired for sale at fair value and mortgage loans at fair value held in a VIE, are categorized as “Level 2” fair value assets. The fair values of mortgage loans acquired for sale at fair value are established using their quoted market or contracted price or market price equivalent. For the mortgage loans at fair value held in a VIE, the quoted fair values of all of the individual securities issued by the securitization trust are used to derive a fair value for the mortgage loans. The Company obtains indications of fair value from nonaffiliated brokers based on comparable securities and validates the brokers’ indications of fair value using pricing models and inputs the Manager believes are similar to the models and inputs used by other market participants.

• Mortgage loans that are not saleable into active markets, comprised of distressed mortgage loans are categorized as “Level 3” fair value assets and their fair values are estimated using a discounted cash flow approach. Inputs to the discounted cash flow model include current interest rates, loan amount, payment status, property type, discount rates and forecasts of future interest rates, home prices, prepayment speeds, default speeds, loss severities and contracted selling price where applicable.

The valuation process includes the computation by stratum of the mortgage loans’ fair values and a review for reasonableness of various measures such as weighted average life, projected prepayment and default speeds, and projected default and loss percentages. The FAV group computes the effect on the valuation of changes in inputs such as interest rates, home prices, and delinquency status to assess the reasonableness of changes in the mortgage loan valuation.

Changes in fair value attributable to changes in instrument-specific credit risk are measured by the effect on fair value of the change in the respective mortgage loan’s delinquency status and performance history at period-end from the later of the beginning of the period or acquisition date.

The significant unobservable inputs used in the fair value measurement of the Company’s mortgage loans at fair value are discount rate, home price projections, voluntary prepayment speeds and default speeds. Significant changes in any of those inputs in isolation could result in a significant change to the mortgage loans’ fair value measurement. Increases in home price projections are generally accompanied by an increase in voluntary prepayment speeds. Changes in the fair value of mortgage loans at fair value are included in Net gain (loss) on investments in the consolidated statements of income.

Following is a quantitative summary of key inputs used in the valuation of mortgage loans at fair value:

Key inputs	March 31, 2017		December 31, 2016
Discount rate
Range	2.8% – 15.0%		2.6% – 15.0%
Weighted average		7.2%		7.1%
Twelve-month projected housing price index change
Range	2.4% – 3.6%		2.5% – 4.8%
Weighted average		3.4%		3.7%
Prepayment speed (1)
Range	0.1% – 6.1%		0.1% – 10.9%
Weighted average		4.0%		4.0%
Total prepayment speed (2)
Range	2.0% – 24.1%		2.9% – 24.6%
Weighted average		17.4%		17.7%

31

(1) Prepayment speed is measured using Life Voluntary Conditional Prepayment Rate (“CPR”).

(2) Total prepayment speed is measured using Life Total CPR.

Excess Servicing Spread Purchased from PFSI

The Company categorizes ESS as a “Level 3” fair value asset. The Company uses a discounted cash flow approach to estimate the fair value of ESS. The key inputs used in the estimation of the fair value of ESS include prepayment speed and discount rate. Significant changes to those inputs in isolation may result in a significant change in the ESS fair value measurement. Changes in these key inputs are not necessarily directly related.

ESS is generally subject to loss in fair value when interest rates decrease. Decreasing mortgage rates normally encourage increased mortgage refinancing activity. Increased refinancing activity reduces the expected life of the mortgage loans underlying the ESS, thereby reducing the cash flows expected to accrue to ESS. Reductions in the fair value of ESS affect income primarily through change in fair value. Changes in the fair value of ESS are included in Net gain (loss) on investments in the consolidated statements of income.

Following are the key inputs used in determining the fair value of ESS:

Key inputs	March 31, 2017		December 31, 2016
UPB of underlying mortgage loans (in thousands)	$	31,154,796	$	32,376,359
Average servicing fee rate (in basis points)		34		34
Average ESS rate (in basis points)		19		19
Pricing spread (1)
Range	3.8% - 4.8%		3.8% - 4.8%
Weighted average		4.4%		4.4%
Life (in years)
Range	1.3 - 8.6		1.4 - 8.6
Weighted average		6.8		6.8
Annual total prepayment speed (2)
Range	7.0% - 46.6%		7.0% - 41.3%
Weighted average		10.3%		10.5%

(1) Pricing spread represents a margin that is applied to a reference interest rate’s forward rate curve to develop periodic discount rates. The Company applies a pricing spread to the United States Dollar London Interbank Offered Rate (“LIBOR”) curve for purposes of discounting cash flows relating to ESS.

(2) Prepayment speed is measured using Life Total CPR.

Derivative Financial Instruments

Interest Rate Lock Commitments

The Company categorizes IRLCs as “Level 3” fair value assets and liabilities. The Company estimates the fair value of IRLCs based on quoted Agency MBS prices, its estimate of the fair value of the MSRs it expects to receive in the sale of the mortgage loan and the probability that the mortgage loans will be purchased under the commitment (the “pull-through rate”).

The significant unobservable inputs used in the fair value measurement of the Company’s IRLCs are the pull-through rate and the MSR component of the Company’s estimate of the fair value of the mortgage loans it has committed to purchase. Significant changes in the pull-through rate or the MSR component of the IRLCs, in isolation, may result in a significant change in fair value. The financial effects of changes in these inputs are generally inversely correlated as increasing interest rates have a positive effect on the fair value of the MSR component of IRLC value, but increase the pull-through rate for the mortgage loan principal and interest payment cash flow component that has decreased in fair value. Changes in fair value of IRLCs are included in Net gain on mortgage loans acquired for sale in the consolidated statements of income.

32

Following is a quantitative summary of key unobservable inputs used in the valuation of IRLCs:

Key inputs	March 31, 2017		December 31, 2016
Pull-through rate
Range	60.5% - 100.0%		60.7% - 100.0%
Weighted average		85.5%		88.5%
MSR value expressed as:
Servicing fee multiple
Range	2.3 - 6.0		2.6 - 6.0
Weighted average		4.7		5.0
Percentage of UPB
Range	0.0% - 1.5%		0.7% - 1.5%
Weighted average		1.2%		1.3%

Hedging Derivatives

The Company estimates the fair value of commitments to sell mortgage loans based on quoted MBS prices. These derivative financial instruments are categorized by the Company as “Level 1” assets and liabilities for those based on exchange traded market prices or as “Level 2” fair value assets and liabilities for those based on observable interest rate volatilities in the MBS market. Changes in the fair value of hedging derivatives are included in Net gain on mortgage loans acquired for sale, Net gain (loss) on investments, or Net mortgage loan servicing fees, as applicable, in the consolidated statements of income.

Real Estate Acquired in Settlement of Loans

REO is measured based on its fair value on a nonrecurring basis and is categorized as a “Level 3” fair value financial assets. Fair value of REO is established by using a current estimate of fair value from a broker’s price opinion or a full appraisal, or the price given in a current contract of sale.

REO fair values are reviewed by the Manager’s staff appraisers when the Company obtains multiple indications of fair value and there is a significant difference between the fair values received. PCM’s staff appraisers will attempt to resolve the difference between the indications of fair value. In circumstances where the appraisers are not able to generate adequate data to support a fair value conclusion, the staff appraisers will order an additional appraisal to determine fair value. Changes in the fair value of REO are included in Results of real estate acquired in settlement of loans in the consolidated statements of income.

Mortgage Servicing Rights

MSRs are categorized as “Level 3” fair value assets. The Company uses a discounted cash flow approach to estimate the fair value of MSRs. The key inputs used in the estimation of the fair value of MSRs include the applicable pricing spread, prepayment and default rates of the underlying mortgage loans, and annual per-loan cost to service mortgage loans, all of which are unobservable. Significant changes to any of those inputs in isolation could result in a significant change in the MSR fair value measurement. Changes in these key inputs are not necessarily directly related. Changes in the fair value of MSRs are included in Net mortgage loan servicing fees in the consolidated statements of income.

MSRs are generally subject to loss in fair value when mortgage interest rates decrease. Decreasing mortgage interest rates normally encourage increased mortgage refinancing activity. Increased refinancing activity reduces the expected life of the underlying mortgage loans, thereby reducing the cash flows expected to accrue to the MSRs. Reductions in the fair value of MSRs affect income primarily through change in fair value and change in impairment. For MSRs backed by mortgage loans with historically low interest rates, factors other than interest rates (such as housing price changes) take on increasing influence on prepayment behavior of the underlying mortgage loans.

33

Following are the key inputs used in determining the fair value of MSRs at the time of initial recognition:

(1) The Company applies a pricing spread to the United States Dollar LIBOR curve for purposes of discounting cash flows relating to MSRs.

(2) For MSRs carried at fair value, an adverse change in one of the above-mentioned key inputs is expected to result in a reduction in fair value which will be recognized in income. For MSRs carried at lower of amortized cost or fair value, an adverse change in one of the above-mentioned key inputs may result in recognition of MSR impairment. The extent of the recognized MSR impairment will depend on the relationship of fair value to the carrying value of such MSRs.

(3) Prepayment speed is measured using Life Total CPR.

The preceding sensitivity analyses are limited in that they were performed at a particular point in time; only account for the estimated effect of the movements in the indicated inputs; do not incorporate changes in the inputs in relation to other inputs; are subject to the accuracy of various models and inputs used; and do not incorporate other factors that would affect the Company’s overall financial performance in such events, including operational adjustments made by the Manager to account for changing circumstances. For these reasons, the preceding estimates should not be viewed as earnings forecasts.

Securities Sold Under Agreements to Repurchase

Fair value of securities sold under agreements to repurchase is based on the accrued cost of the agreements, which approximates the fair values of the agreements, due to the short maturities of such agreements.

Note 8—Mortgage Loans Acquired for Sale at Fair Value

Mortgage loans acquired for sale at fair value is comprised of recently originated mortgage loans purchased by the Company for resale. Following is a summary of the distribution of the Company’s mortgage loans acquired for sale at fair value:

Loan type	March 31, 2017		December 31, 2016
	(in thousands)
Conventional:
Agency-eligible	$	737,902	$	847,810

Mortgage loan participation and sale agreements		75,461		26,738
	$	1,257,927	$	1,653,748

The Company is not approved by Ginnie Mae as an issuer of Ginnie Mae-guaranteed securities which are backed by government-insured or guaranteed mortgage loans. The Company transfers government-insured or guaranteed mortgage loans that it purchases from correspondent lenders to PLS, which is a Ginnie Mae-approved issuer, and earns a sourcing fee ranging from two to three and one-half basis points, generally based on the average number of calendar days that mortgage loans are held prior to purchase by PLS.

Note 9—Derivative Financial Instruments

The Company’s activities involving derivative financial instruments are summarized below:

• The Company recognizes IRLCs in the normal course of business when it commits to purchase mortgage loans acquired for sale.

• The Company enters into CRT Agreements whereby it retains a Recourse Obligation relating to certain mortgage loans it sells into Fannie Mae guaranteed securitizations and an interest-only ownership interest in such mortgage loans. The fair values of the Recourse Obligations and the Company’s retention of the interest-only ownership interest are accounted for as derivative financial instruments.

• The Company engages in interest rate risk management activities in an effort to reduce the variability of earnings caused by the effects of changes in interest rates on the fair value of certain of its assets and liabilities. To manage the price risk resulting from interest rate risk, the Company uses derivative financial instruments acquired with the intention of moderating the risk that changes in market interest rates will result in unfavorable changes in the fair value of the Company’s MBS, inventory of mortgage loans acquired for sale, mortgage loans held in a VIE, ESS, IRLCs and MSRs.

The Company records all derivative financial instruments at fair value and records changes in fair value in current period income.

The Company is exposed to price risk relative to the IRLCs it issues to correspondent sellers and to the mortgage loans it purchases as a result of issuing the IRLCs. The Company bears price risk from the time an IRLC is issued to a correspondent seller to the time the purchased mortgage loan is sold. The Company is exposed to loss if market mortgage interest rates increase, because market interest rate increases generally cause the fair value of the IRLC or mortgage loan acquired for sale to decrease.

Note 14—Mortgage Loan Participation and Sale Agreements

Certain borrowing facilities secured by mortgage loans acquired for sale are in the form of mortgage loan participation and sale agreements. Participation certificates, each of which represents an undivided beneficial ownership interest in a pool of mortgage loans that have been pooled with Fannie Mae or Freddie Mac, are sold to a lender pending the securitization of such mortgage loans and the sale of the resulting security. A commitment between the Company and a nonaffiliate to sell such security is also assigned to the lender at the time a participation certificate is sold.

The purchase price paid by the lender for each participation certificate is based on the trade price of the security, plus an amount of interest expected to accrue on the security to its anticipated delivery date, minus a present value adjustment, any related hedging costs and a holdback amount. The holdback amount is based on a percentage of the purchase price and is not required to be paid to the Company until the settlement of the security and its delivery to the lender.

On March 9, 2017, the Company issued 4,600,000 of its 8.125% Series A Fixed-to-Floating Rate Cumulative Redeemable Preferred Shares of Beneficial Interest, $0.01 par value per share (“Series A Preferred Shares”). From, and including, the date of original issuance to, but not including, March 15, 2024, the Company will pay cumulative dividends on the Series A Preferred Shares at a fixed rate of 8.125% per annum based on the $25.00 per share liquidation preference.

PMT will pay quarterly cumulative dividends on the Series A Preferred Shares, in arrears, on the 15th day of each March, June, September and December, beginning on June 15, 2017 (provided that if any dividend payment date is not a business day, then the dividend that would otherwise have been payable on that dividend payment date may be paid on the next succeeding business day).

The Series A Preferred Shares will not be redeemable before March 15, 2024, except in connection with the Company’s qualification as a REIT for U.S. federal income tax purposes or upon the occurrence of a change of control of the Company as described in the prospectus supplement filed with the SEC on March 6, 2017.

Conditional Reimbursement of IPO Underwriting Costs

As more fully described in Note 3—Transactions with Related Parties, on February 1, 2013, the Company entered into a Reimbursement Agreement, by and among the Company, the Operating Partnership and PCM. The Reimbursement Agreement provides that, to the extent the Company is required to pay PCM performance incentive fees under the management agreement, the Company will reimburse PCM for underwriting costs it paid on the IPO offering date at a rate of $10 in reimbursement for every $100 of performance incentive fees earned. The reimbursement is subject to a maximum reimbursement in any particular 12-month period of $1.0 million, and the maximum amount that may be reimbursed under the agreement is $2.9 million. No payments were made during the quarters ended March 31, 2017 and March 31, 2016.

The Reimbursement Agreement also provides for the payment to the IPO underwriters of the amount that the Company agreed to pay to them at the time of the IPO if the Company satisfied certain performance measures over a specified period of time. As PCM earns performance incentive fees under the management agreement, the IPO underwriters will be paid at a rate of $20 of payments for every $100 of performance incentive fees earned by PCM. The payment to the underwriters is subject to a maximum reimbursement in any particular 12-month period of $2.0 million and the maximum amount that may be paid under the agreement is $5.9 million. No payments were made during the quarters ended March 31, 2017 and March 31, 2016. The Reimbursement Agreement expires on February 1, 2019.

Note 28—Income Taxes

The Company’s effective tax rate was (27.1)% and (31.3)% for the quarters ended March 31, 2017 and 2016, respectively. The Company’s taxable REIT subsidiary recognized a tax benefit of $6.6 million on a loss of $14.8 million while the Company’s reported consolidated pretax income was $22.6 million for the quarter ended March 31, 2017. For the same period in 2016, the Company’s taxable REIT subsidiary recognized a tax benefit of $3.5 million on a loss of $6.0 million while the Company’s reported consolidated pretax income was $11.0 million. The relative values between the tax benefit at the taxable REIT subsidiary and the Company’s consolidated pretax income drive the fluctuation in the effective tax rate. The primary difference between the Company’s effective tax rate and the statutory tax rate is due to non-taxable REIT income resulting from the dividends paid deduction.

In general, cash dividends declared by the Company will be considered ordinary income to shareholders for income tax purposes. Some portion of the dividends may be characterized as capital gain distributions or a return of capital.

Note 29—Segments and Related Information

During the quarter ended March 31, 2017, the Company changed the composition of its operating segments. The reporting used by the Company’s chief operating decision maker changed as the Company’s investment activities have become more diversified. The Manager has focused this broadened investment base on two classes of investments: credit sensitive and interest rate sensitive mortgage related assets.  As this focus has developed, the Manager’s reporting on and management of the Company’s investments has also developed along these lines.  Accordingly, during the quarter ended March 31, 2017, management re-evaluated this new information in relation to its definition of its operating segments.

The Company has redefined its segment reporting to separately distinguish its investment activities between credit sensitive and interest rate sensitive investments and certain corporate activities.

Credit sensitive investment strategies include investments in distressed mortgage loans, REO, CRT Agreements, non-Agency subordinated bonds and small balance commercial real estate mortgage loans. Interest rate sensitive strategies include investments in MSRs, ESS, Agency and senior non-Agency MBS and the related interest rate hedging activities.  The corporate segment includes certain interest income, management fee and corporate expense amounts.

Segment results for the quarter ended March 31, 2016 have been restated to conform prior year presentation to the new segment composition.

Financial highlights by operating segment are summarized below:

Note 32—Recently Issued Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Subtopic 606) (“ASU 2014-09”), which supersedes the guidance in the Revenue Recognition topic of the ASC. ASU 2014-09 clarifies the principles for recognizing revenue in order to improve comparability of revenue recognition practices across entities and industries with certain scope exceptions including financial instruments, leases, and guarantees. ASU 2014-09 provides guidance intended to assist in the identification of contracts with customers and separate performance obligations within those contracts, the determination and allocation of the transaction price to those identified performance obligations and the recognition of revenue when a performance obligation has been satisfied. ASU 2014-09 also requires disclosures regarding the nature, amount, timing, and uncertainty of revenues and cash flows from contracts with customers.

Upon adoption, ASU 2014-09 provides for transition through either a full retrospective approach requiring the restatement of all presented prior periods or a modified retrospective approach, which allows the new recognition standard to be applied to only those contracts that are not completed at the date of transition. If the modified retrospective approach is adopted, a cumulative-effect adjustment to retained earnings is performed with additional disclosures required including the amount by which each line item is affected by the transition as compared to the guidance in effect before adoption and an explanation of the reasons for significant changes in these amounts.

The FASB has issued several amendments to ASU 2014-09, including:

• In August 2015, ASU 2015-14, Revenue From Contracts With Customers (“ASU 2015-14”). This update deferred the initial effective date of ASU 2014-09. As a result of the issuance of ASU 2015-14, ASU 2014-09 is effective for annual reporting periods beginning on or after December 15, 2017, and interim periods within those annual periods. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period.

• In March 2016, ASU 2016-08, Principal Versus Agent Considerations (Reporting Revenue Gross versus Net). The amendments to this update are intended to improve the implementation guidance on principal versus agent considerations in ASU 2014-09 by clarifying how an entity should identify the unit of accounting (i.e. the specified good or service) and how an entity should apply the control principle to certain types of arrangements.

• In May 2016, ASU 2016-12, Narrow-Scope Improvements and Practical Expedients. The amendments to this update clarify certain core recognition principles and provide practical expedients available at transition. The improvements address collectability, sales tax presentation, noncash consideration, contract modifications and completed contracts at transition.

• In December 2016, ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers. The amendments to this update:

o Clarify that guarantee fees within the scope of the Guarantees topic of the ASC (other than product or service warranties) are not within the scope of the Revenue from Contracts with Customers topic of the ASC. Entities should see the Derivatives and Hedging topic of the ASC, for guarantees accounted for as derivatives.

54

o Clarify the Other Assets and Deferred Costs—Contracts with Customers subtopic of the ASC that when performing impairment testing an entity should (a) consider expected contract renewals and extensions and (b) include both the amount of consideration it already has received but has not recognized as revenue and the amount it expects to receive in the future.

o Clarify the interaction of impairment testing with guidance in other ASC topics that impairment testing first should be performed on assets not within the scope of the Other Assets and Deferred Costs, Intangibles-Goodwill and Other and the Property, Plant, and Equipment topics (such as assets within the Inventory topic of the ASC), then assets within the scope of the Other Assets and Deferred Costs topic of the ASC, then asset groups and reporting units within the scope of the Other Assets and Deferred Costs, Intangibles-Goodwill and Other and the Property, Plant, and Equipment topics of the ASC.

o Clarify that all contracts within the scope of the Financial Services – Insurance topic of the ASC are excluded from the scope of the Revenue from Contracts with Customers topic.

o Provide optional exemptions from the disclosure requirement for remaining performance obligations for specific situations in which an entity need not estimate variable consideration to recognize revenue and expands the information that is required to be disclosed when an entity applies one of the optional exemptions.

o Clarify that the disclosure of revenue recognized from performance obligations satisfied (or partially satisfied) in previous periods applies to all performance obligations and is not limited to performance obligations with corresponding contract balances.

• In February 2017, ASU 2017-05, Other Income—Gains and Losses from the Derecognition ofNonfinancial Assets (Subtopic 610-20) (“ASU 2017-05”). The amendments to this update clarify the scope of the Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets subtopic of the ASC, and to add guidance for partial sales of nonfinancial assets. ASU 2017-05 clarifies that:

o A financial asset is within the scope of the Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets subtopic of the ASC if it meets the definition of an in substance nonfinancial asset and defines the term in substance nonfinancial asset, in part, as a financial asset promised to a counterparty in a contract if substantially all of the fair value of the assets (recognized and unrecognized) that are promised to the counterparty in the contract is concentrated in nonfinancial assets.

o It excludes all businesses and nonprofit activities from the scope of the Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets subtopic of the ASC. Derecognition of all businesses and nonprofit activities should be accounted for in accordance with the Consolidation—Overall subtopic of the ASC.

o An entity should identify each distinct nonfinancial asset or in substance nonfinancial asset promised to a counterparty and derecognize each asset when a counterparty obtains control of it.

o An entity should allocate consideration to each distinct asset by applying the guidance in the Revenue from Contracts with Customers topic of the ASC on allocating the transaction price to performance obligations.

o An entity must derecognize a distinct nonfinancial asset or distinct in substance nonfinancial asset in a partial sale transaction when it (1) does not have (or ceases to have) a controlling financial interest in the legal entity that holds the asset in accordance with the Consolidations topic and (2) transfers control of the asset in accordance with the Revenue from Contracts with Customers topic of the ASC. Once an entity transfers control of a distinct nonfinancial asset or distinct in substance nonfinancial asset, it is required to measure any noncontrolling interest it receives (or retains) at fair value.

The Manager is currently evaluating the pending adoption of ASU 2014-09 and its amendments and their impact on the consolidated financial statements. The Manager does not expect the adoption of ASU 2014-09 to have a significant effect on the consolidated financial statements of the Company and has not yet identified which transition method will be applied upon adoption.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments–Overall: Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). ASU 2016-01 affects the accounting for equity investments, financial liabilities under the fair value option, the presentation and disclosure requirements for financial instruments, and the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities.

55

ASU 2016-01 requires that:

• All equity investments in unconsolidated entities (other than those accounted for using the equity method of accounting) with readily determinable fair values will generally be measured at fair value through earnings.

• When the fair value option has been elected for financial liabilities, changes in fair value due to instrument-specific credit risk will be recognized separately in other comprehensive income. The accumulated gains and losses due to these changes will be reclassified from accumulated other comprehensive income to earnings if the financial liability is settled before maturity.

• For financial instruments measured at amortized cost, public business entities will be required to use the exit price when measuring the fair value of financial instruments for disclosure purposes.

• Financial assets and financial liabilities shall be presented separately in the notes to the financial statements, grouped by measurement category (e.g., fair value, amortized cost, lower of cost or fair value) and form of financial asset (e.g., loans, securities).

• Public business entities will no longer be required to disclose the methods and significant assumptions used to estimate the fair value of financial instruments carried at amortized cost.

• Entities will have to assess the realizability of a deferred tax asset related to a debt security classified as available for sale in combination with the entity’s other deferred tax assets.

The classification and measurement guidance will be effective for public business entities in fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption of the provision to record fair value changes for financial liabilities under the fair value option resulting from instrument-specific credit risk in other comprehensive income is permitted and can be elected for all financial statements of fiscal years and interim periods that have not yet been issued or that have not yet been made available for issuance. The Manager does not believe that the adoption of ASU 2016-01 will have a significant effect on its consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). ASU 2016-09 simplifies several aspects of the accounting for share-based payment award transactions, including:

• Modifies the accounting for income taxes relating to share-based payments. All excess tax benefits and tax deficiencies (including tax benefits of dividends on share-based payment awards) will be recognized as income tax expense or benefit in the consolidated statement of income. The tax effects of exercised or vested awards will be treated as discrete items in the reporting period in which they occur. An entity will recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period. Under current GAAP, excess tax benefits are recognized in additional paid-in capital; tax deficiencies are recognized either as an offset to accumulated excess tax benefits, if any, or in the consolidated statement of income in the period they reduce income taxes payable.

• Changes the classification of excess tax benefits on the consolidated statement of cash flows. In the consolidated statement of cash flows, excess tax benefits will be classified along with other income tax cash flows as an operating activity. Under current GAAP, excess tax benefits are separated from other income tax cash flows and classified as a financing activity.

• Changes the requirement to estimate the number of awards that are expected to vest. Under ASC 2016-09, an entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest as presently required or account for forfeitures when they occur. Under current GAAP, accruals of compensation cost are based on the number of awards that are expected to vest.

• Changes the tax withholding requirements for share-based payment awards to qualify for equity accounting. The threshold to qualify for equity classification permits withholding up to the maximum statutory tax rates in the applicable jurisdictions. Under current GAAP, for an award to qualify for equity classification is that an entity cannot partially settle the award in cash in excess of the employer’s minimum statutory withholding requirements.

• Establishes GAAP for the classification of employee taxes paid when an employer withholds shares for tax withholding purposes. Cash paid by an employer when directly withholding shares for tax- withholding purposes should be classified as a financing activity. This guidance establishes GAAP related to the classification of withholding taxes in the statement of cash flows as there is no such guidance under current GAAP.

56

ASU 2016-09 is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any organization in any interim or annual period. The adoption ASU 2016-09 did not have a significant effect on the Company’s consolidated financial statements.

Note 33—Subsequent Events

Management has evaluated all events and transactions through the date the Company issued these consolidated financial statements. During this period:

• On April 28, 2017, the Company, through POP, PMC, PMH and PMC REO Financing Trust, LLC (“REO Subsidiary”), entered into a Second Amended and Restated Master Repurchase Agreement with CSFB, as administrative agent to the buyers, Credit Suisse AG, Cayman Islands Branch, as a buyer (“CS Cayman”), and Alpine Securitization LTD, as a buyer (“Alpine” and, together with CS Cayman, the “CS Buyers”)(the “CS Repurchase Agreement”), pursuant to which POP, PMC and/or PMH, as applicable, finance (i) newly originated mortgage loans that PMC purchases from correspondent lenders pending sale and/or securitization, and (ii) distressed mortgage loans and equity interests in REO Subsidiary owning real estate acquired upon settlement of mortgage loans (the “REO Properties”).

The maximum combined purchase price under the CS Repurchase Agreement, together with the Re-warehouse Facility (as defined below), was increased in connection with the amendment and restatement to $1.5 billion. The maximum combined committed purchase price is $650 million, all of which is committed and available for purchases under the CS Repurchase Agreement to the extent not reduced by purchased amounts outstanding under the Re-warehouse Facility and two other master repurchase agreements entered into by the Company in the ordinary course of its business to finance asset-backed securities with CS Cayman and one of its affiliates.

• On April 28, 2017, the Company, through POP, also entered into a Second Amended and Restated Master Repurchase Agreement with CSFB, as administrative agent, and CS Buyers, pursuant to which POP may sell to CS Buyers, and later repurchase, newly originated mortgage loans for which POP provides financing to third-party mortgage loan originators (the “Re-warehouse Facility”). The maximum combined purchase price under the Re-warehouse Facility, together with the CS Repurchase Agreement, was increased in connection with the amendment and restatement to $1.5 billion. The maximum combined committed purchase price is $650 million, and the committed amount under the Re-warehouse Facility is equal to the lesser of (a) $300 million and (b) the maximum combined committed purchase price less all purchased amounts outstanding under the CS Repurchase Agreement.

• On May 3, 2017, the Company, through PMC, entered into an amendment (the “Repurchase Amendment”) to its Master Repurchase Agreement, dated as of September 14, 2015, by and among Barclays, PMC, PLS and the Company (the “Barclays Repurchase Agreement”), pursuant to which PMC finances newly originated mortgage loans. Under the terms of the Repurchase Amendment, the maximum aggregate purchase price provided for in the Repurchase Agreement was temporarily increased from $400 million to $600 million, the available amount of which is reduced by any outstanding purchase amounts under the Participation Agreement (as defined below) and any borrowed amounts under a loan and security agreement by and among PMC, the Company and Barclays dated September 14, 2015. The period of the increase runs from May 15, 2017 to and including September 30, 2017.

• On May 3, 2017, the Company, through PMC, also entered into an amendment (the “Participation Amendment) to its Mortgage Loan Participation Purchase and Sale Agreement, dated as of September 14, 2015, by and among Barclays, PMC and PLS (the “Participation Agreement”), pursuant to which PMC may sell to Barclays participation certificates, each of which represents an undivided beneficial ownership interest in a pool of mortgage loans that have been pooled with Fannie Mae or Freddie Mac and are pending securitization. Under the terms of the Participation Amendment, the maximum aggregate purchase price provided for in the Participation Agreement was temporarily increased from $400 million to $600 million, the available amount of which is reduced by any outstanding repurchase amounts under the Barclays Repurchase Agreement and any borrowed amounts under a loan and security agreement by and among PMC, the Company and Barclays dated September 14, 2015. The period of the increase runs from May 15, 2017 to and including September 30, 2017.

Our Company

We are a specialty finance company that invests primarily in residential mortgage loans and mortgage-related assets. Our objective is to provide attractive risk-adjusted returns to our investors over the long-term, primarily through dividends and secondarily through capital appreciation. We have pursued this objective largely by investing in distressed mortgage assets and acquiring, pooling and selling newly originated prime credit quality residential mortgage loans (“correspondent production”) and retaining the mortgage servicing rights (“MSRs”). We have also invested in excess servicing spread (“ESS”) on MSRs acquired by PennyMac Loan Services, LLC (“PLS”) and mortgage-backed securities (“MBS”). In 2015, we began investing in credit risk transfer agreements (“CRT Agreements”) on certain of the mortgage loans acquired through our correspondent production activity. Our assets are transitioning away from distressed mortgage loans to investments obtained through our correspondent production such as CRT and MSRs. We have also invested in excess servicing spread (“ESS”) on MSRs acquired by PennyMac Loan Services, LLC (“PLS”), mortgage-backed securities (“MBS”), and commercial real estate loans that finance multifamily and other commercial real estate.

We are externally managed by PNMAC Capital Management, LLC (“PCM”), an investment adviser that specializes in and focuses on, U.S residential mortgage loans. Most of our mortgage loan portfolio is serviced by PLS.

Our objective is to provide attractive risk-adjusted returns to our investors over the long-term, primarily through dividends and secondarily through capital appreciation. Our targeted investments are in the U.S. mortgage market, including credit sensitive assets such as distressed mortgage loans, credit risk transfer agreements (“CRT Agreements”) related to our correspondent production, non-Agency subordinate bonds, small-balance commercial real estate (including multifamily) loans and subordinate interests; and interest rate sensitive assets such as MSRs, ESS, MBS, and non-Agency senior MBS.

We have invested in distressed mortgage loans through direct acquisitions of mortgage loan portfolios from institutions such as banks and mortgage companies. A substantial portion of the nonperforming mortgage loans we have purchased has been acquired from or through one or more subsidiaries of JPMorgan Chase & Co. and of Citigroup Inc.

We seek to maximize the value of the distressed mortgage loans that we acquired using means that are appropriate for the particular loan, including both proprietary and nonproprietary loan modification programs, special servicing and other initiatives focused on avoiding foreclosure, when possible. When we are unable to effect a cure for a mortgage loan delinquency, our objective is timely acquisition and/or liquidation of the property securing the mortgage loan through the use, in part, of short sales and deed-in-lieu of foreclosure programs. During the quarter ended March 31, 2017, we did not acquire distressed mortgage loans and we received proceeds from liquidation, payoffs, paydowns and sales from our portfolio of mortgage loans and real estate acquired in settlement of loans (“REO”) totaling $190.8 million. During the quarter ended March 31, 2016, we did not acquired distressed mortgage loans and we received proceeds from liquidation, payoffs, paydowns and sales from our portfolio of mortgage loans and REO totaling $112.8 million.

58

During the quarter ended March 31, 2017 and March 31, 2016, we purchased newly originated prime credit quality loans with fair values totaling $14.5 billion and $10.2 billion, respectively, in furtherance of our correspondent production business. To the extent that we purchase mortgage loans that are insured by the U.S. Department of Housing and Urban Development (“HUD”) through the Federal Housing Administration (the “FHA”), or insured or guaranteed by the Veterans Administration (the “VA”) or U.S. Department of Agriculture (“USDA”), we and PLS have agreed that PLS will fulfill and purchase such mortgage loans, as PLS is a Ginnie Mae-approved issuer and we are not. This arrangement has enabled us to compete with other correspondent lenders that purchase both government and conventional mortgage loans. We receive a sourcing fee from PLS ranging from two to three and one-half basis points, generally based on the average number of calendar days that mortgage loans are held by us prior to purchase by PLS, on the unpaid principal balance (“UPB”) of each mortgage loan. During the quarter ended March 31, 2017, we received sourcing fees totaling $ 2.9 million relating to $ 9.6 billion in UPB of mortgage loans at fair value that we sold to PLS, as compared to $2.0 million relating to $6.5 billion in UPB loans that we sold to PLS for the same period in 2016.

During the quarter ended March 31, 2017, we received MSRs with fair values at initial recognition totaling $58.7 million compared to $36.2 million for the same period in 2016.

We believe that CRT Agreements are a long-term investment that can produce attractive risk-adjusted returns through our own mortgage production while aligning with Fannie Mae’s strategic goal to attract private capital investment in GSE credit risk. We believe there is significant potential for investment in front-end credit risk transfer and MSRs that result from our correspondent production activities as we redeploy capital from the liquidation of distressed whole loans. During the quarter ended March 31, 2017, we made investments in CRT Agreements totaling $15.8 million and commitments to fund an additional $48.2 million of such agreements and held CRT related investments (composed of restricted cash and derivative financial instruments) totaling $489.5 million at March 31, 2017.

We supplement these activities through our participation in other mortgage-related activities, including:

• Acquisition of REIT-eligible mortgage-backed or mortgage-related securities. We purchased MBS with fair values totaling $251.9 million and $50.7 million during the quarter ended March 31, 2017 and 2016, respectively.

• Acquisition of ESS relating to MSRs held by PFSI. We did not purchase any ESS from PFSI and we received $1.6 million pursuant to a recapture agreement with PFSI, compared to receipt of $1.9 million of ESS pursuant to such recapture agreement for the same period in 2016.

• Acquisition of small balance (typically under $10 million) commercial real estate loans. During the quarter ended March 31, 2017, we acquired $21.1 million in fair value of small balance commercial real estate loans.

• To the extent that we transfer correspondent production loans into private label securitizations, retention of a portion of the securities created in the securitization transaction. Our private label securitization is accounted for as a financing arrangement. Sales of securities included in the securitization are treated as issuances of debt. During the quarter ended March 31, 2017, we did not issue any of such securities.

Our board of trustees has authorized a repurchase program under which we may repurchase up to $200 million of our outstanding common shares. During the quarter ended March 31, 2017, we repurchased approximately 139,000 common shares at a cost of $2.3 million, for a cumulative total of 8.6 million common shares repurchased at a cost of $117.0 million under the program. The repurchased common shares were canceled upon settlement of the repurchase transactions and returned to the authorized but unissued share pool.

We believe that we qualify to be taxed as a real estate investment trust (“REIT”). We believe that we will not be subject to federal income tax on that portion of our income that is distributed to shareholders as long as we meet certain asset, income and share ownership tests. If we fail to qualify as a REIT, and do not qualify for certain statutory relief provisions, our profits will be subject to income taxes and we may be precluded from qualifying as a REIT for the four tax years following the year we lose our REIT qualification. A portion of our activities, including our correspondent production business, is conducted in our TRS, which is subject to corporate federal and state income taxes. Accordingly, we have made a provision for income taxes with respect to the operations of our TRS. We expect that the effective rate for the provision for income taxes may be volatile in future periods. Our goal is to manage the business to take full advantage of the tax benefits afforded to us as a REIT.

During the quarter ended March 31, 2017, we recorded net income of $28.7 million, or $0.40 per diluted share. Our net income for the quarter ended March 31, 2017 reflects net gain on mortgage loans acquired for sale of $19.0 million, supplemented by net gain on investments of $16.7 million and net interest income of $10.9 million. During the quarter ended March 31, 2017, we purchased $14.5 billion in fair value of newly originated mortgage loans. We recognized net gains on such loans totaling approximately $19.0 million including $58.7 million of MSRs retained upon sale of such loans. At March 31, 2017, we held mortgage loans acquired for sale with fair values totaling $1.3 billion, $506.6 million of which were pending sale to PLS.

During the quarter ended March 31, 2016, we recorded net income of $14.5 million, or $0.20 per diluted share. Our net income for the quarter ended March 31, 2016 reflects net interest income of $22.4 million, supplemented by net gains on our investments totaling $3.9 million and net mortgage loan servicing fees of $15.6 million. During the quarter ended March 31, 2016, we purchased $10.2 billion in fair value of newly originated mortgage loans. We recognized gains on such loans totaling approximately $15.0 million, including $36.2 million of MSRs retained upon securitization or sale of such loans.

Our net income increased during the quarter ended March 31, 2017, as compared to the same period in 2016, primarily due to an increase in pretax income in our credit sensitive strategies segment of $11.2 million. Pretax income from this segment was $19.4 million during the quarter ended March 31, 2017, compared to pretax income of $8.3 million for the same period in 2016. During the quarter ended March 31, 2017, our credit sensitive strategies segment benefited from improved performance in its investment in CRT Agreements due to credit spread tightening compounded by growth in our investment in CRT Agreements partially offset by reduced gains on distressed mortgage loans.

60

In our correspondent production activities, our pretax net investment income increased during the quarter ended March 31, 2017, as compared to the same period in 2016, by $0.8 million from $11.7 million to $12.5 million. We received proceeds of $14.9 billion from the sale of mortgage loans during the quarter ended March 31, 2017, as compared to $10.1 billion during the same period in 2016. We issued $5.2 billion of IRLCs relating to Agency mortgage loans in the quarter ended March 31, 2017, an increase of $1.3 billion from the same period in 2016. Our net gain on mortgage loans acquired for sale increased due to an increase in mortgage loan volume that was partially offset by lower margins. Our increase in mortgage volume reflects the continued growth in the number of our correspondent sellers which more than offset the effect of the smaller mortgage origination market in 2017. The decrease in our margins reflects the effects of heightened competition resulting from the smaller mortgage origination market.

Net Investment Income

During the quarter ended March 31, 2017, we recorded net investment income of $64.5 million, comprised primarily of $19.0 million of net gain on mortgage loans acquired for sale, $16.7 million net gain on investments, $11.8 million of net loan servicing fees $10.9 million of net interest income, and $8.3 million of mortgage loan origination fees, partially offset by $4.2 million of losses from results of REO.

During the quarter ended March 31, 2016, we recorded net investment income of $52.2 million, comprised primarily of net interest income of $22.4 million, $15.0 million of net gain on mortgage loans acquired for sale, $15.6 million of net loan servicing fees, and $6.9 million of loan origination fees, partially offset by $6.0 million of losses from results of REO and $3.9 of net loss on investments.

Net investment income includes non-cash fair value adjustments and the fair value of assets created and liabilities incurred in mortgage loan sale transactions and the capitalization and amortization of certain assets and liabilities. Because we have elected, or are required by GAAP, to record our financial assets (comprised of MBS, mortgage loans acquired for sale at fair value, mortgage loans at fair value, ESS, and derivatives), a portion of our MSRs and our asset-backed financing at fair value and interest-only security payable, a substantial portion of the income or loss we record with respect to such assets and liabilities results from non-cash changes in fair value. Net investment income also includes non-cash interest income arising from capitalization of delinquent interest on mortgage loans upon completion of the modification of such loans and accrual of unearned discounts relating to MBS, mortgage loans held in a VIE, and asset-backed financing.

Cash is generated when mortgage loan investments are paid off, paid down or sold, when payments of principal and interest occur on such mortgage loans, generally after they are modified, or when the property securing a mortgage loan that has been settled through acquisition of the property securing the mortgage loan has been sold. We receive proceeds on the sale of mortgage loans acquired for sale that include both cash and our estimate of the fair value of MSRs and we recognize a liability for potential losses relating to representations and warranties created in the mortgage loan sales transactions. We receive cash related to MSRs in the form of mortgage loan servicing fees and we pay cash relating to our provision for representations and warranties when we repurchase mortgage loans from investors. Cash flows relating to hedging instruments are generally produced when the instruments mature or when we effectively cancel the transactions through an offsetting trade.

The following table illustrates the proceeds received during the period from dispositions and paydowns of distressed mortgage loan investments and REO, net gain in fair value that we accumulated over the period during which we owned mortgage loan investments and REO liquidated during the period, and additional net gain realized upon liquidation of such assets:

(1) Represents valuation gains and losses recognized during the period we held the respective asset but excludes the gain or loss recorded upon sale or repayment of the respective asset.

(2) Represents the gain or loss recognized upon sale or repayment of the respective asset.

(3) Excludes $14.8 million in proceeds received during the quarter ended March 31, 2017 from the sale of seasoned loans originally acquired in our correspondent production business.

The amounts included in accumulated gains and gains on liquidation do not include the cost of managing the liquidated assets which may be substantial depending on the collection status of the mortgage loan at acquisition and on our success in working with the borrower to resolve the distress in the mortgage loan. Accumulated gains include the amount of accumulated valuation gains and losses recognized throughout the holding period and, in the case of REO, include estimated direct transaction costs to be incurred in the sale of the property. Accordingly, the preceding amounts do not represent periodic earnings on a cash basis and the amount of gain will have accumulated over varying periods depending on the holding periods for individual assets.

The primary expenses incurred at a loan level in managing our portfolio of distressed assets are servicing and activity fees. From the time of acquisition of the distressed assets through their deboarding dates, we incurred servicing and activity fees of $6.4 million and $3.8 million for assets liquidated during the quarter ended March 31, 2017 and 2016, respectively.

Our net gain on mortgage loans acquired for sale includes both cash and non-cash elements. We receive proceeds on sale that include both cash and our estimate of the fair value of MSRs. We also recognize a liability for potential losses relating to representations and warranties created in the mortgage loan sales transactions.

64

The increase in gain on mortgage loans acquired for sale during the quarter ended March 31, 2017, as compared to the same period in 2016 was due to an increase in mortgage loan volume partially offset by reduced margins. Our increase in mortgage volume reflects the continued growth in our correspondent network which more than the offset the effect of the smaller mortgage market in 2017. The decrease in our margins reflects the effects of heightened price competition in the smaller mortgage market.

Provision for Losses on Representations and Warranties

We provide for our estimate of the future losses that we may be required to incur as a result of our breach of representations and warranties to the purchasers. Our agreements with the purchasers include representations and warranties related to the mortgage loans we sell. The representations and warranties require adherence to purchaser and issuer origination and underwriting guidelines, including but not limited to the validity of the lien securing the mortgage loan, property eligibility, borrower credit, income and asset requirements, and compliance with applicable federal, state and local law.

In the event of a breach of our representations and warranties, we may be required to either repurchase the mortgage loans with the identified defects or indemnify the investor or insurer. In such cases, we bear any subsequent credit loss on the mortgage loans. Our credit loss may be reduced by any recourse we have to correspondent lenders that, in turn, had sold such mortgage loans to us and breached similar or other representations and warranties. In such event, we have the right to seek a recovery of related repurchase losses from that correspondent lender.

The method we use to estimate the liability for representations and warranties is a function of estimated future defaults, mortgage loan repurchase rates, the potential severity of loss in the event of default and the probability of reimbursement by the correspondent mortgage loan seller. We establish a liability at the time mortgage loans are sold and review our liability estimate on a periodic basis.

Following is a summary of the indemnification and repurchase activity and UPB of mortgage loans subject to representations and warranties:

	Quarter ended March 31,

65

During the quarter ended March 31, 2017, we repurchased mortgage loans with UPBs totaling $4.1 million and recorded no net losses charged to the liability for representations and warranties, as compared to repurchases of $3.8 million and net losses of $306,000 during the same period in 2016. The losses we have recorded to date have been moderated by our ability to recover most of the losses inherent in the repurchased mortgage loans from the correspondent sellers. As the outstanding balance of mortgage loans we purchase and sell subject to representations and warranties increases and the mortgage loans sold season, we expect the level of repurchase activity and associated losses may increase.

The amount of the liability for representations and warranties is difficult to estimate and requires considerable judgment. The level of mortgage loan repurchase losses is dependent on economic factors, investor loss mitigation strategies, our ability to recover any losses inherent in the repurchased mortgage loan from the selling correspondent originator and other external conditions that may change over the lives of the underlying mortgage loans. We may be required to incur losses related to such representations and warranties for several periods after the mortgage loans are sold or liquidated.

As economic fundamentals change, and as investor and Agency evaluations of their loss mitigation strategies (including claims under representations and warranties) change and as economic conditions affect our correspondent sellers’ ability or willingness to fulfill their recourse obligations to us, the level of repurchase activity and ensuing losses will change, and we may be required to record adjustments to our recorded liability for losses on representations and warranties which may be material to our financial condition and income. Such adjustments are included as a component of our Net gains on mortgage loans acquired for sale at fair value. We recorded a $4.6 million reduction in liabilities for representations and warranties during the quarter ended March 31, 2017 due to our revised expectation of lower than originally anticipated losses in part due to the effects of the Agencies’ previously announced limitations on claims relating to mortgage loans with certain performance histories preceding their default.

Loan Origination Fees

Loan origination fees represent fees we charge correspondent sellers relating to our purchase of mortgage loans from those sellers. The increase in fees during the quarter ended March 31, 2017, as compared to the same period in 2016 is reflective of the increase in the volume of mortgage loans we purchased during the 2017 period.

Net Gain (Loss) on Investments

Net gain (loss) on investments is summarized below:

	Quarter ended March 31,
	2017			2016
	(in thousands)
Net gain (loss) on investments:
From non-affiliates:
Mortgage-backed securities	$	140		$	5,099

From PFSI—ESS		(1,370	)		(17,627	)
	$	16,721		$	(3,898	)

The increase in net gain (loss) on investments during the quarter ended March 31, 2017, as compared to the same period in 2016, was caused by gains in our CRT Agreements during the quarter ended March 31, 2017 as compared to losses during the quarter ended March 31, 2016 compounded by the growth in the average investment in CRT Agreements. The gain in the quarter ended March 31, 2017 reflects credit spread tightening during the period as compared to credit spread widening during the quarter ended March 31, 2016. This improvement was supplemented by a significantly reduced loss on the Company’s investment in ESS during the quarter ended March 31, 2017. This improvement reflects relative stability of the interest rate environment during the quarter ended March 31, 2017, along with a smaller average investment in ESS as compared to 2016.

66

Mortgage-Backed Securities

During the quarter ended March 31, 2017, we recognized net valuation gains on MBS of $140,000, as compared to net valuation gains of $5.1 million for the quarter ended March 31, 2016. The decrease in gains we recorded for the quarter ended March 31, 2017 reflects the effects of a steeper decline in mortgage interest rates during the quarter ended March 31, 2016, as compared to the quarter ended March 31, 2017.

Mortgage Loans at Fair Value – Distressed Mortgage Loans

Net gains on our investment in distressed mortgage loans at fair value are summarized below:

	Quarter ended March 31,
	2017			2016
	(in thousands)
Valuation changes:
Performing loans	$	5,970		$	4,884
Nonperforming loans		(3,169	)		7,965
		2,801			12,849
Gain on payoffs		415			1,548
Loss on sales		—			(2	)
	$	3,216		$	14,395
Average portfolio balance	$	1,327,421		$	2,064,101
Interest and fees capitalized	$	9,903		$	23,294
Number of mortgage loans relating to gain recognized on payoffs		81			106
UPB of mortgage loans relating to gain recognized on payoffs	$	24,746		$	26,273
Number of mortgage loans relating to loss recognized on sales		373			1
UPB of mortgage loans relating to loss recognized on sales	$	103,767		$	500

Because we have elected to record our mortgage loans at fair value, a substantial portion of the income we record with respect to such mortgage loans results from changes in fair value. Valuation changes amounted to gains of $2.8 million in the quarter ended March 31, 2017, as compared to gains of $12.8 million for the same period in 2016. We recognize gain (loss) relating to mortgage loans subject to pending sales contracts in the valuation changes. Gains on sales represent settlement adjustments realized at the date of sale. Cash is generated when mortgage loans are paid off or sold, when payments of principal and interest occur on such loans, generally after they are modified, or when the property securing a mortgage loan that has been settled through acquisition of the property has been sold.

The valuation changes on performing mortgage loans reflect the effects of capitalization of delinquent interest on loans we modify. When we capitalize interest in a loan modification, we increase the carrying value of the mortgage loan. However, the fair value of the loan does not immediately increase significantly. Therefore, the interest income we recognize is offset by a valuation loss of corresponding magnitude. Changes in other inputs may result in further valuation changes to the mortgage loan, and subsequent performance of a modified mortgage loan will be reflected in its future fair value. During the quarter ended March 31, 2017, we capitalized interest totaling $9.9 million, as compared to $23.3 million for the quarter ended March 31, 2016.

Implementing long-term, sustainable loan modification is one means by which we endeavor to increase the fair value of the distressed mortgage loans which we have typically purchased at discounts to their UPB.

Gains on nonperforming mortgage loans decreased during the quarter ended March 31, 2017 as compared to the same period in 2016 as our expected cash flow realization for certain segments of the portfolio declined due to lower expected recoveries in the event of default as well as higher realized and expected collection costs associated with the resolution of those loans.

Absent sale or securitization of reperforming and modified mortgage loans, and unlike liquidation of a defaulted mortgage loan, we expect that recovery of our investment in a performing modified mortgage loan will take place generally over a period of several years, during which we earn and collect interest income on such mortgage loan. Our current expectation is that we will receive cash on modified mortgage loans through monthly borrower payments, payoffs or acquisition of the property securing the mortgage loans and liquidation of the property in the event the borrower subsequently defaults.

67

Large-scale refinancing of modified distressed mortgage loans is not expected to occur for an extended period. Borrowers who have recently modified their mortgage loans typically have credit profiles that do not qualify them for refinancing or have mortgage loans on properties whose loan-to-value ratios exceed current underwriting guidelines for new mortgage loans. Further, modified mortgage loans generally require a period of acceptable borrower performance for consideration in most Agency refinance programs.

The following tables present a summary of mortgage loan modifications completed:

	Quarter ended March 31,

Carrying value of investments in CRT Agreements (1)	$	489,465		$	465,669

(1) Carrying value of investments in CRT Agreements includes Deposits securing CRT Agreements and CRT derivatives.

The increase in gains recognized on CRT Agreements is due to growth in the portfolio of mortgage loans subject to CRT Agreements during 2017 as compared to 2016 and the effect of credit spread decreases (credit spreads represent the yield premium demanded by investors for securities similar to CRT Agreements as compared to a U.S. Treasury security) on the fair value of the derivative assets included in the CRT Agreements. During 2016, we experienced increased credit spreads related to our CRT Agreements resulting in unrealized losses.

ESS Purchased from PFSI

We recognized fair value losses relating to our investment in ESS totaling $1.4 million for the quarter ended March 31, 2017, as compared to fair value losses of $17.6 million for the quarter ended March 31, 2016. The reduction in losses was driven by the relative stability of the interest rate environment in 2017 compared to the same period in 2016 along with a decrease in our investment in ESS. Our average investment in ESS decreased from $379.3 million for the quarter ended March 31, 2016 to $285.4 million for the quarter ended March 31, 2017.

Net Mortgage Loan Servicing Fees

Our correspondent production activity is the primary source of our mortgage loan servicing portfolio. When we sell mortgage loans, we generally enter into a contract to service the mortgage loans and recognize the fair value of such contracts as MSRs. Under these contracts, we are required to perform mortgage loan servicing functions in exchange for fees and the right to other compensation.

The servicing functions, which are performed on our behalf by PLS, typically include, among other responsibilities, collecting and remitting mortgage loan payments; responding to borrower inquiries; accounting for principal and interest, holding custodial (impound) funds for payment of property taxes and insurance premiums; counseling delinquent mortgagors; and supervising foreclosures and property dispositions.

Net loan servicing fees are summarized below:

Average servicing portfolio	$	57,927,056		$	43,253,977

(1) Includes contractually specified servicing and ancillary fees, net of guarantee fees.

Net loan servicing fees decreased $3.8 million, or 24%, during the quarter ended March 31, 2017, as compared to the same period in 2016. The decrease during the quarter ended March 31, 2017, as compared to the same period in 2016, was primarily due to a $13.6 million increase in the negative effect of MSRs that was caused by a $38.7 million increase in hedge costs that more than offset a $28.6 million decrease in impairment and fair value reduction. This effect was partially offset by an increase in loan servicing fees of $9.6 million, or 33%.

We have entered into an MSR recapture agreement that requires PLS to transfer to us the MSRs with respect to new mortgage loans originated in refinancing transactions where PLS refinances a mortgage loan for which we previously held the MSRs. PLS is generally required to transfer MSRs relating to such mortgage loans (or, under certain circumstances, other mortgage loans) that have an aggregate unpaid principal balance that is not less than 30% of the aggregate unpaid principal balance of all the loans so originated. Where the fair value of the aggregate MSRs to be transferred for the applicable month is less than $200,000, PLS may, at its option, settle in cash with us in an amount equal to such fair market value in place of transferring such MSRs. We recognized MSR recapture income during the quarter ended March 31, 2017 of $292,000, as compared to $130,000 for the quarter ended March 31, 2016.

We have identified two classes of MSRs: originated MSRs backed by mortgage loans with initial interest rates of less than or equal to 4.5% and MSRs backed by mortgage loans with initial interest rates of more than 4.5%. Our accounting for MSRs is based on the class of MSRs. Originated MSRs backed by mortgage loans with initial interest rates of less than or equal to 4.5% are accounted for using the amortization method. Originated MSRs backed by mortgage loans with initial interest rates of more than 4.5% are accounted for at fair value with changes in fair value recorded in current period income.

Net interest income	$	(1,318	)	$	(10,123	)	$	(11,441	)

During the quarter ended March 31, 2017, we earned net interest income of $10.9 million, as compared to $22.4 million for the quarter ended March 31, 2016. The decrease in net interest income between quarters was due to a decrease in average investment in mortgage loans at fair value, which are our highest yielding assets, compounded by the growth in our borrowings to finance non-interest earning MSRs. This reduction was partially offset by growth in our average investment in MBS and mortgage loans acquired for sale.

During the quarter ended March 31, 2017, we recognized interest income on mortgage loans at fair value and mortgage loans at fair value held by VIEs totaling $23.4 million, including $9.9 million of interest capitalized pursuant to loan modifications, which compares to $34.7 million, including $23.3 million of interest capitalized pursuant to loan modifications in the quarter ended March 31, 2016. The decrease in interest income was primarily the result of continuing sales and liquidations of our distressed mortgage loans.

74

At March 31, 2017, approximately 54% of the fair value of our distressed mortgage loan portfolio was nonperforming, as compared to 55% at December 31, 2016. We do not accrue interest on nonperforming mortgage loans and generally do not recognize revenues during the period we hold REO. We calculate the yield on our mortgage loan portfolio based on the portfolio’s average fair value, which most closely reflects our investment in the mortgage loans. Accordingly, the yield we realize is substantially higher than would be recorded based on the mortgage loans’ UPBs and performance status as we generally have purchased our distressed mortgage loans at substantial discounts to their UPB.

Nonperforming mortgage loans and REO generally take longer than performing mortgage loans to generate cash flow due to the time required to work with borrowers to resolve payment issues through our modification programs, and to acquire and liquidate the property securing the mortgage loans. The value and returns we realize from these assets are determined by our ability to assist borrowers in curing defaults, or when curing of borrower defaults is not a viable solution, by our ability to effectively manage the liquidation process. At March 31, 2017, we held $663.6 million in fair value of nonperforming mortgage loans and $224.8 million in carrying value of REO, as compared to $743.0 million in fair value of nonperforming mortgage loans and $274.1 million in carrying value of REO at December 31, 2016.

During the quarter ended March 31, 2017, we incurred interest expense totaling $37.2 million, as compared to $32.0 million during the quarter ended March 31, 2016. Our interest cost on interest bearing liabilities was 3.29% for the quarter ended March 31, 2017 and 3.16% for the quarter ended March 31, 2016. The increase in interest expense reflects higher borrowing costs associated with funding investments in MSRs and ESS in the quarter ended March 31, 2017, as compared to the quarter ended March 31, 2016.

Results of Real Estate Acquired in Settlement of Loans

Results of REO includes the gains or losses we record upon sale of the properties as well as valuation adjustments we record during the period we hold those properties. During the quarter ended March 31, 2017, we recorded net losses of $4.2 million as compared to $6.0 million for the same period in 2016, in Results of real estate acquired in settlement of loans.

Results of REO are summarized below:

	Quarter ended March 31,
	2017			2016
	(dollars in thousands)
During the period:
Proceeds from sales of REO	$	63,224		$	64,908
Results of real estate acquired in settlement of loans:
Valuation adjustments, net		(8,175	)		(10,645	)

End of period:
Carrying value	$	224,831		$	327,212
Number of properties		911			1,501

Losses from REOs during the quarter ended March 31, 2017 decreased from the same period in 2016. The decrease in losses from REOs during the quarter ended March 31, 2017, as compared to 2016, was due to smaller overall REO portfolio during 2017 as compared to 2016.

Expenses

Our expenses are summarized below:

	Quarter ended March 31,
	2017		2016
	(in thousands)
Expenses payable to PFSI:
Mortgage loan fulfillment fees	$	16,570	$	12,935
Mortgage loan servicing fees		10,486		11,453
Management fees		5,008		5,352
Compensation		1,892		1,289
Mortgage loan origination		1,512		1,121
Professional services		1,453		2,293
Mortgage loan collection and liquidation		354		2,214
Other		4,591		4,515
	$	41,866	$	41,172

Expenses increased $694,000, or 2%, during the quarter ended March 31, 2017, as compared to the same period in 2016, primarily due to higher mortgage loan fulfillment fees from an increase in the volume of Agency-eligible mortgage loans we purchased in our correspondent production activities, partially offset by a reduction in mortgage loan collection and liquidation expenses resulting from increased recoveries in 2017 as compared to 2016.

Mortgage Loan Fulfillment Fees

Mortgage loan fulfillment fees represent fees we pay to PLS for the services it performs on our behalf in connection with our acquisition, packaging and sale of mortgage loans. The fee is calculated as a percentage of the UPB of the mortgage loans purchased. Mortgage loan fulfillment fees and related fulfillment volume are summarized below:

	Quarter ended March 31,
	2017		2016
	(dollars in thousands)
Fulfillment fee expense	$	16,570	$	12,935
UPB of mortgage loans fulfilled by PLS	$	4,631,906	$	3,259,363
Average fulfillment fee rate (in basis points)		36		40

The increase in loan fulfillment fees of $3.6 million during the quarter ended March 31, 2017, as compared to the same period in 2016 is primarily due to an increase in the volume of Agency-eligible mortgage loans we purchased in our correspondent production activities, partially offset by a decrease in the average fulfillment fee rate charged by PFSI due to contractual reductions in the fulfillment fee following a change in the mortgage banking services agreement with PFSI in September 2016.

Mortgage Loan Servicing Fees

Mortgage loan servicing fees decreased by $967,000 during the quarter ended March 31, 2017, as compared to the same period in 2016. We incur mortgage loan servicing fees primarily in support of our investment in mortgage loans at fair value and our mortgage loan servicing portfolio. The decrease in mortgage loan servicing fees for the quarter ended March 31, 2017, as compared to the same period in 2016, was primarily due to a decrease in our average investment in distressed mortgage loans at fair value of $736.7 million as a result of the sales and liquidations of our distressed loans during 2016. Servicing fees relating to distressed mortgage loans are significantly higher than those relating to MSRs due to the increased cost of servicing such loans. Therefore, reductions in the balance of distressed mortgage loans have a much more significant effect on mortgage loan servicing fees than the additions of new MSRs.

Management Fees

The components of our management fee payable to PCM are summarized below:

	(in thousands)
Base	$	5,008	$	5,352
Performance incentive		—		—
	$	5,008	$	5,352

Management fees decreased by $344,000 during the quarter ended March 31, 2017, as compared to the same period in 2016, primarily due to the decrease in our shareholders’ equity, which is the basis for the calculation of our base management fee, as a result of our share repurchases and dividend distributions.

We expect our management fees to fluctuate in the future based on: (1) changes in our shareholders’ equity with respect to our base management fee; and (2) the level of our profitability in excess of the return thresholds specified in our management agreement with respect to the performance incentive fee.

Compensation

Compensation expense increased $603,000 during the quarter ended March 31, 2017, as compared to the same period in 2016, primarily due to increased share-based compensation expense, reflecting the effects of a generally higher share price in the 2017 period than in the 2016 period on the portion of our restricted share unit grants that are accounted for using variable accounting.

77

Professional Services

Professional service expense decreased $840,000 during the quarter ended March 31, 2017 as compared to the same period in 2016, primarily due to a decrease in loan monitoring-related expenses resulting from sales and repayments of our portfolio of distressed mortgage loans and to initial costs relating to the CRT Agreements during 2016 that did not recur during 2017.

Mortgage loan collection and liquidation

Mortgage loan collection and liquidation expenses decreased $1.9 million during the quarter ended March 31, 2017, as compared to the same period in 2016, due to an increase in recoveries of previously incurred costs that we realized during 2017, as compared to 2016.

Other Expenses

Other expenses are summarized below:

	Quarter ended March 31,
	2017		2016

Common overhead allocation from PFSI	$	1,434	$	2,561

Insurance		338		318
Technology		318		435
Other		1,413		644
	$	4,591	$	4,515

Other expenses increased during the quarter ended March 31, 2017, as compared to the same period in 2016 by $76,000, primarily due to higher expenses incurred in the management of our real estate held for investment partially offset by a reduction in common overhead allocation from PFSI.

Income Taxes

We have elected to treat PMC as a taxable REIT subsidiary (“TRS”). Income from a TRS is only included as a component of REIT taxable income to the extent that the TRS makes dividend distributions of income to the REIT. No such dividend distributions have been made to date. A TRS is subject to corporate federal and state income tax. Accordingly, a provision for income taxes for PMC is included in the accompanying consolidated statements of operations.

Our effective tax rate was (27.1)% and (31.3)% for the quarter ended March 31, 2017 and 2016, respectively. Our taxable REIT subsidiary recognized a tax benefit of $6.6 million on a loss of $14.8 million while our consolidated pretax income was $22.6 million for the quarter ended March 31, 2017. For the same period in 2016, the taxable REIT subsidiary recognized a tax benefit of $3.5 million on a loss of $6.0 million while our consolidated pretax income was $11.0 million. The relative values between the tax benefit at the taxable REIT subsidiary and our consolidated pretax income drive the fluctuation in the effective tax rate. The primary difference between our effective tax rate and the statutory tax rate is due to non-taxable REIT income resulting from the dividends paid deduction.

In general, cash dividends declared by us will be considered ordinary income to shareholders for income tax purposes. Some portion of the dividends may be characterized as capital gain distributions or as return of capital.

These reductions were offset by a $224.5 million increase in MBS and a $13.8 million increase in deposits securing CRT Agreements.

The increase in correspondent purchases during the quarter ended March 31, 2017, as compared to the same period in 2016, is a result of the interest rate environment and continued growth in our correspondent production seller network.

Our ability to continue the expansion of our correspondent production business is subject to, among other factors, our ability to source additional mortgage loan volume, our ability to obtain additional inventory financing and our ability to fund the portion of the mortgage loans not financed, either through cash flows from business activities or the raising of additional equity capital. There can be no assurance that we will be successful in increasing our borrowing capacity or in obtaining the additional equity capital necessary or that we will be able to identify additional sources of mortgage loans.

Investment Activities

Following is a summary of our acquisitions of mortgage-related investments held in our interest rate sensitive strategies and credit-sensitive strategies segments:

	Quarter ended March 31,
	2017		2016
	(in thousands)
MBS	$	251,872	$	50,702
MSRs received in mortgage loan sales and purchases of MSRs		58,688		38,764

Additional commitments to fund deposits securing CRT Agreements		48,150		—
	$	374,503	$	156,172

Our acquisitions during the quarter ended March 31, 2017 and 2016 were financed through the use of a combination of proceeds from liquidations of existing investments and borrowings. We continue to identify additional means of increasing our investment portfolio through cash flow from our business activities, existing investments, borrowings, and transactions that minimize current cash outlays. However, we expect that, over time, our ability to continue our investment activities portfolio growth will depend on our ability to raise additional equity capital.

Mortgage Loans at Fair Value – Distressed

The relationship of the fair value of our distressed mortgage loans at fair value to the underlying real estate collateral is summarized below:

	March 31, 2017				December 31, 2016
	Loan		Collateral		Loan		Collateral
	(in thousands)
Fair values:
Performing loans	$	565,982	$	863,451	$	611,584	$	957,313
Nonperforming loans		663,571		1,016,425		742,988		1,123,277
	$	1,229,553	$	1,879,876	$	1,354,572	$	2,080,590

The collateral values presented above do not represent our assessment of the amount of future cash flows to be realized from the mortgage loans and/or underlying collateral. Future cash flows will be influenced by, among other considerations, our asset disposition strategies with respect to individual loans and the timing of such dispositions, the costs and expenses we incur in the disposition process, changes in borrower performance and the underlying collateral values. Ultimate realization in a disposition of these assets will be net of any servicing advances held on the balance sheet in relation to these investments.

The collateral values summarized above are estimated and may change over time due to various factors including our level of access to the properties securing the loans, changes in the real estate market or the condition of individual properties. The collateral values presented do not include any costs that would typically be incurred in obtaining the property in settlement of the mortgage loan, readying the property for sale, holding the property while it is being marketed or in the sale of a property.

We believe that our current fair value estimates are representative of fair value at the reporting date. However, the market for distressed mortgage assets is illiquid with a limited number of participants. Furthermore, our business strategy is to enhance value during the period in which the loans are held. Therefore, any resulting appreciation or depreciation in the fair value of the loans is recorded during such holding period and ultimately realized at the end of the holding period.

Following is a comparison of the key inputs we use in the valuation of our mortgage loans at fair value using “Level 3” fair value inputs:

Key inputs	March 31, 2017		December 31, 2016
Discount rate
Range	2.8% – 15.0%		2.6% – 15.0%
Weighted average		7.2%		7.1%
Twelve-month projected housing price index change
Range	2.4% – 3.6%		2.5% – 4.8%
Weighted average		3.4%		3.7%
Prepayment speed (1)
Range	0.1% – 6.1%		0.1% – 10.9%
Weighted average		4.0%		4.0%
Total prepayment speed (2)
Range	2.0% – 24.1%		2.9% – 24.6%
Weighted average		17.4%		17.7%

(1) Prepayment speed is measured using Life Voluntary CPR.

(2) Total prepayment speed is measured using Life Total CPR.

We monitor and value our investments in pools of distressed mortgage loans by payment status of the loans. Most of the measures we use to value and monitor the loan portfolio, such as projected prepayment and default speeds and discount rates, are applied or output at the pool level. The characteristics of the individual loans, such as loan size, loan-to-value ratio and current delinquency status, can vary widely within a pool.

The weighted average discount rate used in the valuation of mortgage loans at fair value increased slightly from 7.1% at December 31, 2016 to 7.2% at March 31, 2017 due to shifting characteristics of the portfolio given liquidations and loans sales in the period.

The weighted average twelve-month projected housing price index change used in the valuation of our portfolio of mortgage loans at fair value decreased from 3.7% at December 31, 2016 to 3.4 % at March 31, 2017, due to slightly lower near term forecasts for real estate price appreciation in the geographic areas in which our portfolio of mortgage loans is concentrated.

The weighted average total prepayment speed used in the valuation of our portfolio of mortgage loans at fair value decreased slightly from 17.7% at December 31, 2016 to 17.4 % at March 31, 2017 due to our projections of longer liquidation periods for certain of our mortgage loans.

Cash Flows

Our cash flows for the quarter ended March 31, 2017 and 2016 are summarized below:

	Quarter ended March 31,
	2017			2016			Change
	(in thousands)
Operating activities	$	395,383		$	(39,570	)	$	434,953
Investing activities		42,023			93,069			(51,046	)
Financing activities		(351,833	)		(44,635	)		(307,198	)
Net cash flows	$	85,573		$	8,864		$	76,709

Our cash flows resulted in a net increase in cash of $ 85.6 million during the quarter ended March 31, 2017, as discussed below.

Operating activities

Cash provided by operating activities totaled $395.4 million during the quarter ended March 31, 2017, as compared to cash used by operating activities of $39.6 million during the quarter ended March 31, 2016.  The increase in cash flows used by operating activities is primarily due to the reduction of our inventory of mortgage loans acquired for sale during the quarter ended March 31, 2017 as compared to the same period in 2016.

Investing activities

Net cash provided by our investing activities was $42.0 million for the quarter ended March 31, 2017, as compared to cash provided by investing activities of $93.1 million for the quarter ended March 31, 2016. The decrease in cash flows from investing activities reflects the increased purchases of MBS, offset by the benefits of reduced up front funding requirements relating to deposits securing CRT Agreements and the sale of reperforming mortgage loans.

Our investing activities have included the purchase of long-term assets which are not presently cash flowing or are at risk of interruption of cash flows in the near future. Furthermore, much of the investment income we recognize is in the form of valuation adjustments we record recognizing our estimates of the net appreciation in value of the assets as we work with borrowers to either modify their loans or acquire the property securing their loans in settlement thereof. Accordingly, the cash associated with a substantial portion of our revenues is often realized as part of the proceeds of the liquidation of the assets, either through payoff or sale of the mortgage loan or through acquisition and subsequent sale of the property securing the mortgage loans, many months after we record the revenues.

Financing activities

Net cash used in financing activities was $351.8 million for the quarter ended March 31, 2017, as compared to $44.6 million for the quarter ended March 31, 2016. We reduced assets sold under agreements to repurchase as a result of our reduced inventory of mortgage loans held for sale and through the use of proceeds of our preferred share issuance to pay down amounts outstanding.

We do not raise equity or enter into borrowings for the purpose of financing the payment of dividends. We believe that our cash flows from the liquidation of our investments, which include accumulated gains recorded during the periods we hold those investments, along with our cash earnings, are adequate to fund our operating expenses and dividend payment requirements. However, we manage our liquidity in the aggregate and are reinvesting our cash flows in new investments as well as using such cash to fund our dividend requirements.

Liquidity and Capital Resources

Our liquidity reflects our ability to meet our current obligations (including the purchase of loans from correspondent lenders, our operating expenses and, when applicable, retirement of, and margin calls relating to, our debt and derivatives positions), make investments as our Manager identifies them, pursue our share repurchase program and make distributions to our shareholders. We generally need to distribute at least 90% of our taxable income each year (subject to certain adjustments) to our shareholders to qualify as a REIT under the Internal Revenue Code. This distribution requirement limits our ability to retain earnings and thereby replenish or increase capital to support our activities.

We expect our primary sources of liquidity to be proceeds from liquidations from our investment portfolio, including distressed assets, cash earnings on our investments, cash flows from business activities, and proceeds from borrowings and/or additional equity

87

offerings. When we finance a particular asset, the amount borrowed is less than the asset’s value and we must provide the cash in the amount of such difference. Our ability to continue making investments is dependent on our ability to invest the cash representing such difference. Further, certain of our CRT Agreements may allow us, at the time we sell a mortgage loan, to deposit less than the full amount of cash we would otherwise be required to deposit with respect to such loan until the end of the aggregation period relating to the applicable CRT Agreement. At the end of such aggregation period, we will be required to deposit all remaining cash necessary to fully secure the related CRT Agreement, and our ability to fully invest in such CRT Agreement is dependent on our ability to deposit the required cash. We believe that our liquidity is sufficient to meet our current liquidity needs.

We do not expect repayments from contractual cash flows from our investments to be a primary source of liquidity as the majority of our investments are distressed assets that are nonperforming. Our portfolio of distressed mortgage loans was acquired with the expectation that the majority of the cash flows associated with these investments would result from liquidation of the property securing the loan, rather than from scheduled principal and interest payments. Our mortgage loans acquired for sale are generally held for fifteen days or less and, therefore, are not expected to generate significant cash flows from principal repayments.

Our current leverage strategy is to finance our assets where we believe such borrowing is prudent, appropriate and available. We have made collateralized borrowings in the form of sales of assets under agreements to repurchase, mortgage loan participation and sale agreements and notes payable. We also previously made collateralized borrowings in the form of borrowings under forward purchase agreements and advances from the Federal Home Loan Bank of Des Moines. To the extent available to us, we expect in the future to obtain long-term financing for assets with estimated future lives of more than one year; this may include term financing and securitization of performing, nonperforming and/or reperforming mortgage loans.

We will continue to finance most of our assets on a short-term basis until long-term financing becomes more available. Our short-term financings will be primarily in the form of agreements to repurchase and other secured lending and structured finance facilities, pending the ultimate disposition of the assets, whether through sale, securitization or liquidation. Because a significant portion of our current debt facilities consists of short-term borrowings, we expect to renew these facilities in advance of maturity in order to ensure our ongoing liquidity and access to capital or otherwise allow ourselves sufficient time to replace any necessary financing.

As of March 31, 2017 and December 31, 2016, we financed our investments in MBS, mortgage loans acquired for sale at fair value, mortgage loans at fair value, mortgage loans at fair value held by a VIE, MSRs, ESS, REO and deposits securing CRT Agreements with sales under agreements to repurchase, notes payable, asset-backed financing and mortgage loan participation and sale agreements. Following is a summary of our borrowings as of the dates presented:

	March 31, 2017			December 31, 2016
	(dollars in thousands)
Assets financed	$	6,712,143		$	5,814,378
Total assets in classes of assets financed	$	5,655,741		$	5,962,987
Secured borrowings (1)	$	4,164,095		$	4,589,606
Percentage of invested assets pledged		119	%		98	%
Advance rate against pledged assets		62	%		79	%
Leverage ratio (2)	3.02x			3.58x

(1) Excludes the effect of unamortized debt issuance costs.

(2) All borrowings divided by shareholders’ equity at end of period.

Our repurchase agreements represent the sales of assets together with agreements for us to buy back the assets at a later date. Following is a summary of the activities in our repurchase agreements financing:

	Quarter ended March 31,
Assets sold under agreements to repurchase	2017		2016
	(in thousands)
Average balance outstanding	$	3,267,864	$	2,797,301
Maximum daily balance outstanding	$	4,330,825	$	3,577,236
Ending balance	$	3,500,190	$	3,245,014

The difference between the maximum and average daily amounts outstanding is primarily due to increasing volume and the timing of loan purchases and sales in our correspondent acquisition business. The total facility size of our assets sold under agreements to repurchase was approximately $5.2 billion at March 31, 2017.

88

As discussed above, all of our repurchase agreements, notes payable, and mortgage loan participation and sale agreements have short-term maturities:

• The transactions relating to mortgage loans and REO under agreements to repurchase generally provide for terms of approximately one year.

• The transactions relating to mortgage loans under mortgage loan participation and sale agreements provide for terms of approximately one year.

• The transactions relating to assets under notes payable provide for terms of approximately one year.

As of March 31, 2017, leverage on MSRs and ESS continues to be limited in availability due to the requirement of each Agency that its rights and interest in the MSRs remain senior to those of any lender extending credit. As we continue to aggregate MSRs and ESS, the limited availability of financing could place stress on our capital and liquidity positions or require us to forego attractive investment opportunities.

Our debt financing agreements require us and certain of our subsidiaries to comply with various financial covenants. As of the filing of this Report, these financial covenants include the following:

• profitability at the Company for at least one (1) of the previous two consecutive fiscal quarters, as of the end of each fiscal quarter, and over the prior six month period measured at each calendar quarter end, and at the Company and our Operating Partnership over the prior three (3) calendar quarters;

• a minimum of $40 million in unrestricted cash and cash equivalents among the Company and/or our subsidiaries; a minimum of $40 million in unrestricted cash and cash equivalents among our Operating Partnership and its consolidated subsidiaries; a minimum of $25 million in unrestricted cash and cash equivalents between PMC and PMH; and a minimum of $10 million in unrestricted cash and cash equivalents at each of PMC and PMH;

• a minimum tangible net worth for the Company of $860 million; a minimum tangible net worth for our Operating Partnership of $700 million; a minimum tangible net worth for PMH of $250 million; and a minimum tangible net worth for PMC of $150 million;

• a maximum ratio of total liabilities to tangible net worth of less than 10:1 for PMC and PMH and 5:1 for the Company and our Operating Partnership; and

• at least two warehouse or repurchase facilities that finance amounts and assets similar to those being financed under our existing debt financing agreements.

Although these financial covenants limit the amount of indebtedness we may incur and impact our liquidity through minimum cash reserve requirements, we believe that these covenants currently provide us with sufficient flexibility to successfully operate our business and obtain the financing necessary to achieve that purpose.

PLS is also subject to various financial covenants, both as a borrower under its own financing arrangements and as our servicer under certain of our debt financing agreements. The most significant of these financial covenants currently include the following:

• positive net income during each calendar quarter;

• a minimum in unrestricted cash and cash equivalents of $20 million;

• a minimum tangible net worth of $200 million; and

• a maximum ratio of total liabilities to tangible net worth of 10:1.

In addition to the financial covenants imposed upon us and PLS under our debt financing agreements, we are also subject to liquidity and net worth requirements established by FHFA for Agency seller/servicers and Ginnie Mae for single-family issuers. FHFA and Ginnie Mae have established minimum liquidity and their net worth requirements for approved non-depository single-family sellers/servicers in the case of FHFA, and for approved single-family issuers in the case of Ginnie Mae, as summarized below:

• A minimum net worth of a base of $2.5 million plus 25 basis points of UPB for total 1-4 unit residential mortgage loans serviced.

• A tangible net worth/total assets ratio greater than or equal to 6%.

• Liquidity equal to or exceeding 3.5 basis points multiplied by the aggregate UPB of all mortgages secured by 1-4 unit residential properties serviced for Freddie Mac, Fannie Mae and Ginnie Mae (“Agency Mortgage Servicing”) plus 200 basis points multiplied by the sum of nonperforming (90 or more days delinquent) Agency Mortgage Servicing that exceed 6% of Agency Mortgage Servicing.

89

• In the case of PLS, liquidity equal to the greater of $1.0 million or 0.10% (10 basis points) of its outstanding Ginnie Mae single-family securities, which must be met with cash and cash equivalents.

• In the case of PLS, net worth equal to $2.5 million plus 0.35% (35 basis points) of its outstanding Ginnie Mae single-family obligations.

Our debt financing agreements also contain margin call provisions that, upon notice from the applicable lender at its option, require us to transfer cash or, in some instances, additional assets in an amount sufficient to eliminate any margin deficit. A margin deficit will generally result from any decline in the market value (as determined by the applicable lender) of the assets subject to the related financing agreement, although in some instances we may agree with the lender upon certain thresholds (in dollar amounts or percentages based on the market value of the assets) that must be exceeded before a margin deficit will arise. Upon notice from the applicable lender, we will generally be required to satisfy the margin call on the day of such notice or within one business day thereafter, depending on the timing of the notice.

Our Manager continues to explore a variety of additional means of financing our growth, including debt financing through bank warehouse lines of credit, repurchase agreements, term financing, securitization transactions and additional equity offerings. However, there can be no assurance as to how much additional financing capacity such efforts will produce, what form the financing will take or that such efforts will be successful.

Quantitative and Qualitative Disclosures About Market Risk

Market risk is the exposure to loss resulting from changes in interest rates, foreign currency exchange rates, commodity prices, equity prices, real estate values and other market-based risks. The primary market risks that we are exposed to are real estate risk, credit risk, interest rate risk, prepayment risk, inflation risk and market value risk. Our primary trading asset is our inventory of mortgage loans acquired for sale. We believe that such assets’ fair values respond primarily to changes in the market interest rates for comparable recently-originated mortgage loans. Our other market-risk assets are a substantial portion of our investments and are comprised of distressed mortgage nonperforming loans and MSRs. We believe that the fair values of MSRs also respond primarily to changes in the market interest rates for comparable mortgage loans. We believe that the fair values of our investment in distressed mortgage loans respond primarily to changes in the fair value of the real estate securing such loans.

The following sensitivity analyses are limited in that they were performed at a particular point in time; only contemplate the movements in the indicated variables; do not incorporate changes to other variables; are subject to the accuracy of various models and assumptions used; and do not incorporate other factors that would affect our overall financial performance in such scenarios, including operational adjustments made by management to account for changing circumstances. For these reasons, the following estimates should not be viewed as earnings forecasts.

Organization Consolidation And Presentation Of Financial Statements [Abstract]

Organization and Basis of Presentation

Note 1—Organization and Basis of Presentation

PennyMac Mortgage Investment Trust (“PMT” or the “Company”) was organized in Maryland on May 18, 2009, and commenced operations on August 4, 2009, when it completed its initial offerings of common shares of beneficial interest (“common shares”). The Company is a specialty finance company, which, through its subsidiaries (all of which are wholly-owned), invests primarily in residential mortgage-related assets.

The Company operates in four segments: correspondent production, credit sensitive strategies, interest rate sensitive strategies and corporate:

• The correspondent production segment represents the Company’s operations aimed at serving as an intermediary between mortgage lenders and the capital markets by purchasing, pooling and reselling newly originated prime credit quality mortgage loans either directly or in the form of mortgage-backed securities (“MBS”), using the services of PNMAC Capital Management, LLC (“PCM” or the “Manager”) and PennyMac Loan Services, LLC (“PLS”), both indirect controlled subsidiaries of PennyMac Financial Services, Inc. (“PFSI”).

Most of the mortgage loans the Company has acquired in its correspondent production activities have been eligible for sale to government-sponsored entities such as the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”) or through government agencies such as the Government National Mortgage Association (“Ginnie Mae”). Fannie Mae, Freddie Mac and Ginnie Mae are each referred to as an “Agency” and, collectively, as the “Agencies.”

• The credit sensitive strategies segment represents the Company’s investments in distressed mortgage loans, real estate acquired in settlement of mortgage loans (“REO”), credit risk transfer agreements (“CRT Agreements”), non-Agency subordinated bonds and small balance commercial real estate mortgage loans.

• The interest rate sensitive strategies segment represents the Company’s investments in mortgage servicing rights (“MSRs”), excess servicing spread (“ESS”), Agency and senior non-Agency MBS and the related interest rate hedging activities.  

• The corporate segment includes certain interest income, management fee and corporate expense amounts.

The Company believes that it qualifies, and has elected to be taxed, as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended, beginning with its taxable period ended on December 31, 2009. To maintain its tax status as a REIT, the Company has to distribute at least 90% of its taxable income in the form of qualifying distributions to shareholders.

The Company conducts substantially all of its operations and makes substantially all of its investments through its subsidiary, PennyMac Operating Partnership, L.P. (the “Operating Partnership”), and the Operating Partnership’s subsidiaries. A wholly-owned subsidiary of the Company is the sole general partner, and the Company is the sole limited partner, of the Operating Partnership.

The accompanying consolidated financial statements have been prepared in compliance with accounting principles generally accepted in the United States (“GAAP”) as codified in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) for interim financial information and with the Securities and Exchange Commission’s instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, these financial statements and notes do not include all of the information required by GAAP for complete financial statements. The interim consolidated information should be read together with the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

The accompanying unaudited consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, but are not necessarily indicative of the results of operations that may be anticipated for the full year. Intercompany accounts and transactions have been eliminated.

Preparation of financial statements in compliance with GAAP requires the Manager to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the reporting period. Actual results will likely differ from those estimates.

Risks And Uncertainties [Abstract]

Concentration of Risks

Note 2—Concentration of Risks

As discussed in Note 1— Organization and Basis of Presentation above, PMT’s operations and investing activities are centered in residential mortgage-related assets, a substantial portion of which were distressed at acquisition. The mortgage loans at fair value not acquired for sale or held in a variable interest entity (“VIE”) are generally purchased at discounts reflecting their distressed state or perceived higher risk of default, as well as a greater likelihood of collateral documentation deficiencies.

Due to the nature of the Company’s investments, PMT is exposed, to a greater extent than traditional mortgage investors, to the risks associated with loan resolution, including that borrowers may be in economic distress and/or may have become unemployed, bankrupt or otherwise unable or unwilling to make payments when due, and that fluctuations in the residential real estate market may affect the performance of its investments. Factors influencing these risks include, but are not limited to:

• changes in the overall economy, unemployment rates and residential real estate values in the markets where the properties securing the Company’s mortgage loans are located;

• PCM’s ability to identify and PLS’ ability to execute optimal resolutions of certain mortgage loans;

• the accuracy of valuation information obtained during the Company’s due diligence activities;

• PCM’s ability to effectively model, and to develop appropriate model inputs that properly anticipate, future outcomes;

• the level of government support for resolution of certain mortgage loans and the effect of current and future proposed and enacted legislative and regulatory changes on the Company’s ability to effect cures or resolutions to distressed mortgage loans; and

• regulatory, judicial and legislative support of the foreclosure process, and the resulting effect on the Company’s ability to acquire and liquidate the real estate securing its portfolio of distressed mortgage loans in a timely manner or at all.

Due to these uncertainties, there can be no assurance that risk management activities identified and executed on PMT’s behalf will prevent significant losses arising from the Company’s investments in real estate-related assets.

A substantial portion of the distressed mortgage loans and REO has been acquired by the Company in prior years from or through one or more subsidiaries of Citigroup Inc. and JPMorgan Chase & Co., as presented in the following summary:

Operating Activities

Correspondent Production Activities

The Company is provided fulfillment and other services by PLS under a mortgage banking services agreement. The Company’s mortgage banking services agreement provides for a fulfillment fee paid to PLS based on the type of mortgage loan that the Company acquires. The fulfillment fee is equal to a percentage of the unpaid principal balance of mortgage loans purchased by the Company. PLS has also agreed to provide such services exclusively for the Company’s benefit, and PLS and its affiliates are prohibited from providing such services for any other party.

Before September 12, 2016, the applicable fulfillment fee percentages were (i) 0.50% for conventional mortgage loans, (ii) 0.88% for loans sold in accordance with the Ginnie Mae Mortgage-Backed Securities Guide, and (iii) 0.50% for all other mortgage loans not contemplated above; provided, however, that PLS was permitted, in its sole discretion, to reduce the amount of the applicable fulfillment fee and credit the amount of such reduction to any reimbursement that would have otherwise been due based on volumes tied to the aggregate unpaid principal balance of the mortgage loans purchased by the Company in the related month. This reduction was only credited to the reimbursement applicable to the month in which the related mortgage was funded.

Effective as of September 12, 2016, pursuant to the terms of an amended and restated mortgage banking services agreement the applicable fulfillment fee percentages are (i) 0.35% for mortgage loans sold or delivered to Fannie Mae or Freddie Mac, and (ii) 0.85% for all other mortgage loans; provided however, that no fulfillment fee shall be due or payable to PLS with respect to any mortgage loans underwritten to Ginnie Mae guidelines. The Company does not hold the Ginnie Mae approval required to issue securities guaranteed by Ginnie Mae MBS and act as a servicer. Accordingly, under the agreement, PLS currently purchases loans salable in accordance with the Ginnie Mae Mortgage-Backed Securities Guide “as is” and without recourse of any kind from the Company at cost less any administrative fees paid by the Correspondent to PMT plus accrued interest and a sourcing fee ranging from two to three and one-half basis points, generally based on the average number of calendar days loans are held by the Company prior to purchase by PLS. The discretionary reductions and volume reimbursements described above are no longer in effect.

In consideration for the mortgage banking services provided by PLS with respect to the Company’s acquisition of mortgage loans under PLS’s early purchase program, PLS is entitled to fees accruing (i) at a rate equal to $1,500 per annum per early purchase facility, and (ii) in the amount of $35 for each mortgage loan that the Company acquires.

The mortgage banking services agreement expires on September 12, 2020, subject to automatic renewal for additional 18-month periods, unless terminated earlier in accordance with the terms of the agreement.

Mortgage Loan Servicing Activities

The Company, through its Operating Partnership, has a mortgage loan servicing agreement with PLS. The servicing agreement provides for servicing fees earned by PLS that are based on a percentage of the mortgage loan’s unpaid principal balance or fixed per loan monthly amounts based on the delinquency, bankruptcy and/or foreclosure status of the serviced mortgage loan or the REO. PLS is also entitled to market-based fees and charges including boarding and deboarding fees, liquidation and disposition, assumption, modification and origination fees and late charges relating to mortgage loans it services for the Company. The servicing agreement was amended and restated as of September 12, 2016; however, the fee structure was not amended in any material respect.

• The base servicing fees for distressed mortgage loans are calculated based on a monthly per-loan dollar amount, with the actual dollar amount for each mortgage loan based on the delinquency, bankruptcy and/or foreclosure status of such mortgage loan or the related underlying real estate. Presently, the base servicing fees for distressed mortgage loans range from $30 per month for current mortgage loans up to $100 per month for mortgage loans where the borrower has declared bankruptcy. PLS is also entitled to certain activity-based fees for distressed mortgage loans that are charged based on the achievement of certain events. These fees range from 0.50% for a streamline modification to 1.50% for a liquidation and $500 for a deed-in-lieu of foreclosure. PLS is not entitled to earn more than one liquidation fee, reperformance fee or modification fee in any 18-month period.

• The base servicing fee rate for REO is $75 per month. To the extent that the Company rents its REO under an REO rental program, the Company pays PLS an REO rental fee of $30 per month per REO, an REO property lease renewal fee of $100 per lease renewal, and a property management fee in an amount equal to PLS’ cost if property management services and/or any related software costs are outsourced to a third-party property management firm or 9% of gross rental income if PLS provides property management services directly. PLS is also entitled to retain any tenant paid application fees and late rent fees and seek reimbursement for certain third party vendor fees.

• The base servicing fees for non-distressed mortgage loans subserviced by PLS on the Company’s behalf are also calculated through a monthly per-loan dollar amount, with the actual dollar amount for each loan based on whether the mortgage loan is a fixed-rate or adjustable-rate loan. The base servicing fees for loans subserviced on the Company’s behalf are $7.50 per month for fixed-rate loans and $8.50 per month for adjustable-rate mortgage loans.

• To the extent that these non-distressed mortgage loans become delinquent, PLS is entitled to an additional servicing fee per mortgage loan ranging from $10 to $55 per month and based on the delinquency, bankruptcy and foreclosure status of the mortgage loan or $75 per month if the underlying mortgaged property becomes REO. PLS is also entitled to customary ancillary income and certain market-based fees and charges, including boarding and deboarding fees, liquidation and disposition fees, assumption, modification and origination fees.

• PLS is required to provide a range of services and activities significantly greater in scope than the services provided in connection with a customary servicing arrangement because the Company does not have any employees or infrastructure. For these services, PLS received a supplemental fee of $25 per month for each distressed whole loan. PLS is entitled to reimbursement for all customary, good faith reasonable and necessary out-of-pocket expenses incurred in performance of its servicing obligations.

• PLS, on behalf of the Company, is entitled to retain any incentive payments made to it and to which it is entitled under the U.S. Department of Treasury’s Home Affordable Modification Plan (“HAMP”); provided, however, that with respect to any such incentive payments paid to PLS under HAMP in connection with a mortgage loan modification for which the Company previously paid PLS a modification fee, PLS shall reimburse the Company an amount equal to the incentive payments.

The term of the servicing agreement, as amended, expires on September 12, 2020, subject to automatic renewal for additional 18-month periods, unless terminated earlier in accordance with the terms of the servicing agreement.

Pursuant to the terms of an MSR recapture agreement, if PLS refinances through its consumer direct lending business mortgage loans for which the Company previously held the MSRs, PLS is generally required to transfer and convey to one of the Company’s wholly-owned subsidiaries without cost to the Company, the MSRs with respect to new mortgage loans originated in those refinancings (or, under certain circumstances, other mortgage loans) that have an aggregate unpaid principal balance that is not less than 30% of the aggregate unpaid principal balance of all the loans so originated. Where the fair value of the aggregate MSRs to be transferred for the applicable month is less than $200,000, PLS may, at its option, pay cash to the Company in an amount equal to such fair value instead of transferring such MSRs.

The MSR recapture agreement was amended and restated as of September 12, 2016; however, the fee structure was not amended in any material respect. The MSR recapture agreement expires, unless terminated earlier in accordance with the agreement, on September 12, 2020, subject to automatic renewal for additional 18-month periods.

Management Fees

Under a management agreement, the Company pays PCM management fees as follows:

• A base management fee that is calculated quarterly and is equal to the sum of (i) 1.5% per year of average shareholders’ equity up to $2 billion, (ii) 1.375% per year of average shareholders’ equity in excess of $2 billion and up to $5 billion, and (iii) 1.25% per year of average shareholders’ equity in excess of $5 billion.

• A performance incentive fee that is calculated at a defined annualized percentage of the amount by which “net income,” on a rolling four-quarter basis and before deducting the incentive fee, exceeds certain levels of return on “equity.”

The performance incentive fee is calculated quarterly and is equal to: (a) 10% of the amount by which net income for the quarter exceeds (i) an 8% return on equity plus the high watermark, up to (ii) a 12% return on equity; plus (b) 15% of the amount by which net income for the quarter exceeds (i) a 12% return on equity plus the high watermark, up to (ii) a 16% return on equity; plus (c) 20% of the amount by which net income for the quarter exceeds a 16% return on equity plus the high watermark.

For the purpose of determining the amount of the performance incentive fee:

“Net income” is defined as net income or loss computed in accordance with GAAP and certain other non-cash charges determined after discussions between PCM and PMT’s independent trustees and after approval by a majority of PMT’s independent trustees.

“Equity” is the weighted average of the issue price per common share of all of PMT’s public offerings, multiplied by the weighted average number of common shares outstanding (including restricted share units) in the rolling four-quarter period.

The “high watermark” is the quarterly adjustment that reflects the amount by which the net income (stated as a percentage of return on equity) in that quarter exceeds or falls short of the lesser of 8% and the Fannie Mae MBS yield (the target yield) for such quarter. The “high watermark” starts at zero and is adjusted quarterly. If the net income is lower than the target yield, the high watermark is increased by the difference. If the net income is higher than the target yield, the high watermark is reduced by the difference. Each time a performance incentive fee is earned, the high watermark returns to zero. As a result, the threshold amounts required for PCM to earn a performance incentive fee are adjusted cumulatively based on the performance of PMT’s net income over (or under) the target yield, until the net income in excess of the target yield exceeds the then-current cumulative high watermark amount, and a performance incentive fee is earned.

The base management fee and the performance incentive fee are both payable quarterly in arrears. The performance incentive fee may be paid in cash or a combination of cash and PMT’s common shares (subject to a limit of no more than 50% paid in common shares), at the Company’s option.

The management agreement was amended and restated as of September 12, 2016; however, the fee structure was not amended in any material respect. Following is a summary of the base management and performance incentive fees payable to PCM recorded by the Company:

	Quarter ended March 31,
	2017		2016
	(in thousands)
Base management	$	5,008	$	5,352
Performance incentive		—		—
	$	5,008	$	5,352

In the event of termination of the management agreement between the Company and PFSI, PFSI may be entitled to a termination fee in certain circumstances. The termination fee is equal to three times the sum of (a) the average annual base management fee, and (b) the average annual performance incentive fee earned by PFSI, in each case during the 24-month period before termination.

Expense Reimbursement and Amounts Payable to and Receivable from PFSI

Under the management agreement, PCM is entitled to reimbursement of its organizational and operating expenses, including third-party expenses, incurred on the Company’s behalf, it being understood that PCM and its affiliates shall allocate a portion of their personnel’s time to provide certain legal, tax and investor relations services for the direct benefit of the Company. With respect to the allocation of PCM’s and its affiliates personnel, from and after September 12, 2016, PCM shall be reimbursed $120,000 per fiscal quarter, such amount to be reviewed annually and to not preclude reimbursement for any other services performed by PCM or its affiliates.

The Company is required to pay PCM and its affiliates a pro rata portion of rent, telephone, utilities, office furniture, equipment, machinery and other office, internal and overhead expenses of PCM and its affiliates required for the Company’s and its subsidiaries’ operations. These expenses will be allocated based on the ratio of the Company’s and its subsidiaries’ proportion of gross assets compared to all remaining gross assets managed by PCM as calculated at each fiscal quarter end:

Investing Activities

On February 29, 2016, the Company and PLS terminated that certain master spread acquisition and MSR servicing agreement that the parties entered into effective February 1, 2013 (the “2/1/13 Spread Acquisition Agreement”) and all amendments thereto. In connection with the termination of the 2/1/13 Spread Acquisition Agreement, PLS reacquired from the Company all of its right, title and interest in and to all of the Fannie Mae ESS previously sold by PLS to the Company under the 2/1/13 Spread Acquisition Agreement and then subject to such 2/1/13 Spread Acquisition Agreement. On February 29, 2016, PLS also reacquired from the Company all of its right, title and interest in and to all of the Freddie Mac ESS previously sold to the Company by PLS. The amount of ESS sold by the Company to PLS under these reacquisitions was $59.0 million.

Financing Activities

PFSI held 75,000 of the Company’s common shares at both March 31, 2017 and December 31, 2016.

Repurchase Agreement with PLS

On December 19, 2016, the Company, through a wholly-owned subsidiary, PennyMac Holdings, LLC (“PMH”), entered into a master repurchase agreement with PLS (the “PMH Repurchase Agreement”), pursuant to which PMH may borrow from PLS for the purpose of financing PMH’s participation certificates representing beneficial ownership in ESS. PLS then re-pledges such participation certificates to PNMAC GMSR ISSUER TRUST (the “Issuer Trust”) under a master repurchase agreement by and among PLS, the Issuer Trust and Private National Mortgage Acceptance Company, LLC, as guarantor (the “PC Repurchase Agreement”). The Issuer Trust was formed for the purpose of allowing PLS to finance MSRs and ESS relating to such MSRs (the “GNMA MSR Facility”).

In connection with the GNMA MSR Facility, PLS pledges and/or sells to the Issuer Trust participation certificates representing beneficial interests in MSRs and ESS pursuant to the terms of the PC Repurchase Agreement. In return, the Issuer Trust (a) has issued to PLS, pursuant to the terms of an indenture, the Series 2016-MSRVF1 Variable Funding Note, dated December 19, 2016, known as the “PNMAC GMSR ISSUER TRUST MSR Collateralized Notes, Series 2016-MSRVF1” (the “VFN”), and (b) may, from time to time pursuant to the terms of any supplemental indenture, issue to institutional investors additional term notes (“Term Notes”), in each case secured on a pari passu basis by the participation certificates relating to the MSRs and ESS. The maximum principal balance of the VFN is $1,000,000,000.

The principal amount paid by PLS for the participation certificates under the PMH Repurchase Agreement is based upon a percentage of the market value of the underlying ESS. Upon PMH’s repurchase of the participation certificates, PMH is required to repay PLS the principal amount relating thereto plus accrued interest (at a rate reflective of the current market and consistent with the weighted average note rate of the VFN and any outstanding Term Notes) to the date of such repurchase. PLS is then required to repay the Issuer Trust the corresponding amount under the PC Repurchase Agreement.

Note Payable to PLS

Before entering into the PMH Repurchase Agreement, PLS was a party to a repurchase agreement between it and Credit Suisse First Boston Mortgage Capital LLC (“CSFB”) (the “MSR Repo”), pursuant to which PLS financed Ginnie Mae MSRs and servicing advance receivables and pledged all of its rights and interests in any Ginnie Mae MSRs it owned to CSFB, and a separate acknowledgement agreement with respect thereto, by and among Ginnie Mae, CSFB and PLS. In connection with the MSR Repo, the Company was party to an underlying loan and security agreement with PLS, pursuant to which the Company was able to borrow up to $150 million from PLS for the purpose of financing its investment in ESS (the “Underlying LSA”). The principal amount of the borrowings under the Underlying LSA was based upon a percentage of the market value of the ESS pledged to PLS, subject to the $150 million sublimit described above. Pursuant to the Underlying LSA, the Company granted to PLS a security interest in all of its right, title and interest in, to and under the ESS pledged to secure the borrowings, and PLS, in turn, re-pledged such ESS to CSFB under the MSR Repo. Interest accrued on the Company’s note relating to the Underlying LSA at a rate based on CSFB’s cost of funds under the MSR Repo. The underlying LSA was terminated in connection with the execution of the PMH Agreement.

Conditional Reimbursement of Initial Public Offering (“IPO”) Underwriting Fees

In connection with its IPO, the Company conditionally agreed to reimburse PCM up to $2.9 million for underwriting fees paid to the IPO underwriters by PCM on the Company’s behalf (the “Conditional Reimbursement”). Also in connection with its IPO, the Company agreed to pay the IPO underwriters up to $5.9 million in contingent underwriting fees.

Earnings Per Share [Abstract]

Earnings Per Share

Note 4—Earnings Per Share

The Company grants restricted share units which entitle the recipients to receive dividend equivalents during the vesting period on a basis equivalent to the dividends paid to holders of common shares. Unvested share-based compensation awards containing non-forfeitable rights to receive dividends or dividend equivalents (collectively, “dividends”) are classified as “participating securities” and are included in the basic earnings per share calculation using the two-class method.

Under the two-class method, all earnings (distributed and undistributed) are allocated to common shares and participating securities, based on their respective rights to receive dividends. Basic earnings per share is determined by dividing net income, reduced by income attributable to the participating securities, by the weighted-average common shares outstanding during the period.

Diluted earnings per share is determined by dividing net income attributable to diluted shareholders, which adds back to net income the interest expense, net of applicable income taxes, on the Company’s exchangeable senior notes (the “Exchangeable Notes”), by the weighted-average common shares outstanding, assuming all dilutive securities were issued. In periods in which the Company records a loss, potentially dilutive securities are excluded from the diluted loss per share calculation, as their effect on loss per share is anti-dilutive.

The following table summarizes the basic and diluted earnings per share calculations:

Credit Risk Transfer Agreements

The Company, through its wholly-owned subsidiary, PennyMac Corp. (“PMC”), entered into CRT Agreements with Fannie Mae, pursuant to which PMC, through subsidiary trust entities, sells pools of mortgage loans into Fannie Mae-guaranteed securitizations while retaining a portion of the credit risk underlying such mortgage loans (“Recourse Obligations”) as part of the retention of an interest-only ownership interest in such mortgage loans.  The mortgage loans subject to the CRT Agreements are transferred by PMC to subsidiary trust entities which sell the mortgage loans into Fannie Mae mortgage loan securitizations. Transfers of mortgage loans subject to CRT Agreements receive sale accounting treatment upon fulfillment of the criteria for sale recognition contained in the Transfers and Servicing topic of the ASC. The pledged cash represents the Company’s maximum contractual exposure to claims under its Recourse Obligations and is the sole source of settlement of losses under the CRT Agreements. Gains and losses on net derivatives related to CRT Agreements are included in Net gain on investments in the consolidated statements of income.

Jumbo Mortgage Loan Financing

On September 30, 2013, the Company completed a securitization transaction in which PMT Loan Trust 2013-J1, a VIE, issued $537.0 million in UPB of certificates backed by fixed-rate prime jumbo mortgage loans, at a 3.9% weighted yield. The Company initially retained $366.8 million in fair value of such certificates. During the quarter ended March 31, 2016 the Company sold $100.6 million in UPB of those certificates, which reduced the fair value of the certificates retained by the Company to $9.1 million as of March 31, 2017. The Company included the proceeds from the sales in Asset backed financing of a variable interest entity at fair value. The Company issued no certificates during the quarter ended March 31, 2017.

Netting of Financial Instruments

Note 6—Netting of Financial Instruments

The Company uses derivative financial instruments to manage exposure to interest rate risk created by its MBS, interest rate lock commitments (“IRLCs”), mortgage loans acquired for sale at fair value, mortgage loans at fair value held in a VIE, ESS and MSRs. All derivative financial instruments are recorded on the consolidated balance sheets at fair value. The Company has elected to net derivative asset and liability positions, and cash collateral obtained from (or posted to) its counterparties when subject to a legally enforceable master netting arrangement. The derivative financial instruments that are not subject to master netting arrangements are IRLCs and the derivatives related to CRT Agreements. As of March 31, 2017 and December 31, 2016, the Company did not enter into reverse repurchase agreements or securities lending transactions that are required to be disclosed in the following tables.

Following is a summary of net derivative assets.

Fair Value

Fair Value Disclosures [Abstract]

Fair Value

Note 7—Fair Value

The Company’s consolidated financial statements include assets and liabilities that are measured based on their fair values. Measurement at fair value may be on a recurring or nonrecurring basis depending on the accounting principles applicable to the specific asset or liability and whether the Manager has elected to carry the item at its fair value as discussed in the following paragraphs.

The Company groups its assets and liabilities at fair value in three levels, based on the markets in which the assets and liabilities are traded and the observability of the inputs used to determine fair value. These levels are:

• Level 1—Quoted prices in active markets for identical assets or liabilities.

• Level 2—Prices determined or determinable using other significant observable inputs. Observable inputs are inputs that other market participants would use in pricing the asset or liability and are developed based on market data obtained from sources independent of the Company. These may include quoted prices for similar assets or liabilities, interest rates, prepayment speeds, credit risk and other inputs.

• Level 3—Prices determined using significant unobservable inputs. In situations where significant observable inputs are unavailable unobservable inputs may be used. Unobservable inputs reflect the Company’s own judgments about the factors that market participants use in pricing assets and liabilities, and are based on the best information available in the circumstances.

As a result of the difficulty in observing certain significant valuation inputs affecting “Level 3” fair value assets and liabilities, the Manager is required to make judgments regarding these items’ fair values. Different persons in possession of the same facts may reasonably arrive at different conclusions as to the inputs to be applied in valuing these assets and liabilities and to their fair values. Likewise, due to the general illiquidity of some of these assets and liabilities, subsequent transactions may be at values significantly different from those reported.

Fair Value Accounting Elections

The Manager identified all of the Company’s non-cash financial assets and MSRs relating to non-commercial real estate secured mortgage loans with initial interest rates of more than 4.5%, to be accounted for at fair value. The Manager has elected to account for these assets at fair value so such changes in fair value will be reflected in income as they occur and more timely reflect the results of the Company’s performance.

The Manager has also identified the Company’s asset-backed financing of a VIE and interest only security payable at fair value to be accounted for at fair value to reflect the generally offsetting changes in fair value of these borrowings to changes in fair value of mortgage loans at fair value or other assets collateralizing these financings. For other borrowings, the Manager has determined that historical cost accounting is more appropriate because under this method debt issuance costs are amortized over the term of the debt, thereby matching the debt issuance cost to the periods benefiting from the availability of the debt.

	$	(5,556	)	$	(26,822	)

Real Estate Acquired in Settlement of Loans

The Company evaluates its REO for impairment with reference to the respective properties’ fair values less cost to sell on a nonrecurring basis. The initial carrying value of the REO is measured at cost as indicated by the purchase price in the case of purchased REO or as measured by the fair value of the mortgage loan immediately before REO acquisition in the case of acquisition in settlement of a loan. REO may be subsequently revalued due to the Company receiving greater access to the property, the property being held for an extended period or receiving indications that the property’s value may not be supported by developing market conditions. Any subsequent change in fair value to a level that is less than or equal to the property’s cost is recognized in Results of real estate acquired in settlement of loans in the Company’s consolidated statements of income.

Mortgage Servicing Rights at Lower of Amortized Cost or Fair Value

The Company evaluates its MSRs at lower of amortized cost or fair value for impairment with reference to the asset’s fair value. For purposes of performing its MSR impairment evaluation, the Company stratifies its MSRs at lower of amortized cost or fair value based on the interest rates borne by the mortgage loans underlying the MSRs. Mortgage loans are grouped into pools with 50 basis point interest rate ranges for fixed-rate mortgage loans with interest rates between 3.0% and 4.5% and a single pool for mortgage loans with interest rates below 3.0%. MSRs relating to adjustable rate mortgage loans with initial interest rates of 4.5% or less are evaluated in a single pool. If the fair value of MSRs in any of the interest rate pools is below the amortized cost of the MSRs, those MSRs are impaired.

When MSRs are impaired, the impairment is recognized in current-period income and the carrying value of the MSRs is adjusted using a valuation allowance. If the fair value of the MSRs subsequently increases, the increase in fair value is recognized in current period income only to the extent of the valuation allowance for the respective impairment stratum.

The Manager periodically reviews the various impairment strata to determine whether the fair value of the impaired MSRs in a given stratum is likely to recover. When the Manager deems recovery of fair value to be unlikely in the foreseeable future, a write-down of the cost of the MSRs for that stratum to its estimated recoverable value is charged to the valuation allowance.

Fair Value of Financial Instruments Carried at Amortized Cost

Certain of the Company’s borrowings are carried at amortized cost. The Company’s Assets sold under agreements to repurchase, Mortgage loan participation and sale agreements, Notes payable, Exchangeable senior notes, Assets sold to PennyMac Financial Services, Inc. under agreements to repurchase and Federal Home Loan Bank advances are classified as “Level 3” fair value assets and liabilities due to the Company’s reliance on unobservable inputs to estimate these instruments’ fair values.

The Manager has concluded that the fair values of Assets sold under agreements to repurchase, Mortgage loan participation and sale agreements, and Notes payable approximate the agreements’ carrying values due to the borrowing agreements’ short terms and variable interest rates. The fair value of the Exchangeable senior notes at March 31, 2017 and December 31, 2016 was $244.0 million and $240.7 million, respectively. The fair value of the Exchangeable senior notes is estimated using a broker indication of  fair value.

Valuation Techniques and Inputs

Most of the Company’s assets, its Derivative liabilities, the Asset-backed financing of a VIE and the Interest-only security payable are carried at fair value with changes in fair value recognized in current period income. A substantial portion of these items are “Level 3” fair value assets and liabilities which require the use of unobservable inputs that are significant to the estimation of the assets and liabilities’ fair values. Unobservable inputs reflect the Company’s own judgments about the factors that market participants use in pricing an asset or liability, and are based on the best information available under the circumstances.

Due to the difficulty in estimating the fair values of “Level 3” fair value assets and liabilities, the Manager has assigned responsibility for estimating fair value of these assets and liabilities to specialized staff and subjects the valuation process to significant executive management oversight. The Manager’s Financial Analysis and Valuation group (the “FAV group”) is responsible for estimating the fair values of “Level 3” fair value assets and liabilities other than IRLCs and maintaining its valuation policies and procedures.

With respect to the Company’s non-IRLC “Level 3” fair value assets and liabilities, the FAV group reports to PCM’s valuation committee, which oversees and approves the valuations. The FAV group monitors the models used for valuation of the Company’s non-IRLC “Level 3” fair value assets and liabilities, including the models’ performance versus actual results, and reports those results to PCM’s valuation committee. PCM’s valuation committee includes PFSI’s executive chairman and chief executive, chief financial, chief enterprise operations, chief risk and deputy chief financial officers.

The FAV group is responsible for reporting to PCM’s valuation committee on a monthly basis on the changes in the valuation of the non-IRLC “Level 3” assets and liabilities, including major factors affecting the valuation and any changes in model methods and inputs. To assess the reasonableness of its valuations, the FAV group presents an analysis of the effect on the valuation of changes to the significant inputs to the models.

The fair value of the Company’s IRLCs is developed by the Manager’s Capital Markets Risk Management staff and is reviewed by the Manager’s Capital Markets Operations group.

The following is a description of the techniques and inputs used in estimating the fair values of “Level 2” and “Level 3” fair value assets and liabilities:

Mortgage-Backed Securities

The Company categorizes its current holdings of MBS as “Level 2” fair value assets. Fair value of these MBS is established based on quoted market prices for the Company’s MBS or similar securities. Changes in the fair value of MBS are included in Net gain (loss) on investments in the consolidated statements of income.

Mortgage Loans

Fair value of mortgage loans is estimated based on whether the mortgage loans are saleable into active markets:

• Mortgage loans that are saleable into active markets, comprised of the Company’s mortgage loans acquired for sale at fair value and mortgage loans at fair value held in a VIE, are categorized as “Level 2” fair value assets. The fair values of mortgage loans acquired for sale at fair value are established using their quoted market or contracted price or market price equivalent. For the mortgage loans at fair value held in a VIE, the quoted fair values of all of the individual securities issued by the securitization trust are used to derive a fair value for the mortgage loans. The Company obtains indications of fair value from nonaffiliated brokers based on comparable securities and validates the brokers’ indications of fair value using pricing models and inputs the Manager believes are similar to the models and inputs used by other market participants.

• Mortgage loans that are not saleable into active markets, comprised of distressed mortgage loans are categorized as “Level 3” fair value assets and their fair values are estimated using a discounted cash flow approach. Inputs to the discounted cash flow model include current interest rates, loan amount, payment status, property type, discount rates and forecasts of future interest rates, home prices, prepayment speeds, default speeds, loss severities and contracted selling price where applicable.

The valuation process includes the computation by stratum of the mortgage loans’ fair values and a review for reasonableness of various measures such as weighted average life, projected prepayment and default speeds, and projected default and loss percentages. The FAV group computes the effect on the valuation of changes in inputs such as interest rates, home prices, and delinquency status to assess the reasonableness of changes in the mortgage loan valuation.

Changes in fair value attributable to changes in instrument-specific credit risk are measured by the effect on fair value of the change in the respective mortgage loan’s delinquency status and performance history at period-end from the later of the beginning of the period or acquisition date.

The significant unobservable inputs used in the fair value measurement of the Company’s mortgage loans at fair value are discount rate, home price projections, voluntary prepayment speeds and default speeds. Significant changes in any of those inputs in isolation could result in a significant change to the mortgage loans’ fair value measurement. Increases in home price projections are generally accompanied by an increase in voluntary prepayment speeds. Changes in the fair value of mortgage loans at fair value are included in Net gain (loss) on investments in the consolidated statements of income.

Following is a quantitative summary of key inputs used in the valuation of mortgage loans at fair value:

Key inputs	March 31, 2017		December 31, 2016
Discount rate
Range	2.8% – 15.0%		2.6% – 15.0%
Weighted average		7.2%		7.1%
Twelve-month projected housing price index change
Range	2.4% – 3.6%		2.5% – 4.8%
Weighted average		3.4%		3.7%
Prepayment speed (1)
Range	0.1% – 6.1%		0.1% – 10.9%
Weighted average		4.0%		4.0%
Total prepayment speed (2)
Range	2.0% – 24.1%		2.9% – 24.6%
Weighted average		17.4%		17.7%

(1) Prepayment speed is measured using Life Voluntary Conditional Prepayment Rate (“CPR”).

(2) Total prepayment speed is measured using Life Total CPR.

Excess Servicing Spread Purchased from PFSI

The Company categorizes ESS as a “Level 3” fair value asset. The Company uses a discounted cash flow approach to estimate the fair value of ESS. The key inputs used in the estimation of the fair value of ESS include prepayment speed and discount rate. Significant changes to those inputs in isolation may result in a significant change in the ESS fair value measurement. Changes in these key inputs are not necessarily directly related.

ESS is generally subject to loss in fair value when interest rates decrease. Decreasing mortgage rates normally encourage increased mortgage refinancing activity. Increased refinancing activity reduces the expected life of the mortgage loans underlying the ESS, thereby reducing the cash flows expected to accrue to ESS. Reductions in the fair value of ESS affect income primarily through change in fair value. Changes in the fair value of ESS are included in Net gain (loss) on investments in the consolidated statements of income.

Following are the key inputs used in determining the fair value of ESS:

Key inputs	March 31, 2017		December 31, 2016
UPB of underlying mortgage loans (in thousands)	$	31,154,796	$	32,376,359
Average servicing fee rate (in basis points)		34		34
Average ESS rate (in basis points)		19		19
Pricing spread (1)
Range	3.8% - 4.8%		3.8% - 4.8%
Weighted average		4.4%		4.4%
Life (in years)
Range	1.3 - 8.6		1.4 - 8.6
Weighted average		6.8		6.8
Annual total prepayment speed (2)
Range	7.0% - 46.6%		7.0% - 41.3%
Weighted average		10.3%		10.5%

(1) Pricing spread represents a margin that is applied to a reference interest rate’s forward rate curve to develop periodic discount rates. The Company applies a pricing spread to the United States Dollar London Interbank Offered Rate (“LIBOR”) curve for purposes of discounting cash flows relating to ESS.

(2) Prepayment speed is measured using Life Total CPR.

Derivative Financial Instruments

Interest Rate Lock Commitments

The Company categorizes IRLCs as “Level 3” fair value assets and liabilities. The Company estimates the fair value of IRLCs based on quoted Agency MBS prices, its estimate of the fair value of the MSRs it expects to receive in the sale of the mortgage loan and the probability that the mortgage loans will be purchased under the commitment (the “pull-through rate”).

The significant unobservable inputs used in the fair value measurement of the Company’s IRLCs are the pull-through rate and the MSR component of the Company’s estimate of the fair value of the mortgage loans it has committed to purchase. Significant changes in the pull-through rate or the MSR component of the IRLCs, in isolation, may result in a significant change in fair value. The financial effects of changes in these inputs are generally inversely correlated as increasing interest rates have a positive effect on the fair value of the MSR component of IRLC value, but increase the pull-through rate for the mortgage loan principal and interest payment cash flow component that has decreased in fair value. Changes in fair value of IRLCs are included in Net gain on mortgage loans acquired for sale in the consolidated statements of income.

Following is a quantitative summary of key unobservable inputs used in the valuation of IRLCs:

Key inputs	March 31, 2017		December 31, 2016
Pull-through rate
Range	60.5% - 100.0%		60.7% - 100.0%
Weighted average		85.5%		88.5%
MSR value expressed as:
Servicing fee multiple
Range	2.3 - 6.0		2.6 - 6.0
Weighted average		4.7		5.0
Percentage of UPB
Range	0.0% - 1.5%		0.7% - 1.5%
Weighted average		1.2%		1.3%

Hedging Derivatives

The Company estimates the fair value of commitments to sell mortgage loans based on quoted MBS prices. These derivative financial instruments are categorized by the Company as “Level 1” assets and liabilities for those based on exchange traded market prices or as “Level 2” fair value assets and liabilities for those based on observable interest rate volatilities in the MBS market. Changes in the fair value of hedging derivatives are included in Net gain on mortgage loans acquired for sale, Net gain (loss) on investments, or Net mortgage loan servicing fees, as applicable, in the consolidated statements of income.

Real Estate Acquired in Settlement of Loans

REO is measured based on its fair value on a nonrecurring basis and is categorized as a “Level 3” fair value financial assets. Fair value of REO is established by using a current estimate of fair value from a broker’s price opinion or a full appraisal, or the price given in a current contract of sale.

REO fair values are reviewed by the Manager’s staff appraisers when the Company obtains multiple indications of fair value and there is a significant difference between the fair values received. PCM’s staff appraisers will attempt to resolve the difference between the indications of fair value. In circumstances where the appraisers are not able to generate adequate data to support a fair value conclusion, the staff appraisers will order an additional appraisal to determine fair value. Changes in the fair value of REO are included in Results of real estate acquired in settlement of loans in the consolidated statements of income.

Mortgage Servicing Rights

MSRs are categorized as “Level 3” fair value assets. The Company uses a discounted cash flow approach to estimate the fair value of MSRs. The key inputs used in the estimation of the fair value of MSRs include the applicable pricing spread, prepayment and default rates of the underlying mortgage loans, and annual per-loan cost to service mortgage loans, all of which are unobservable. Significant changes to any of those inputs in isolation could result in a significant change in the MSR fair value measurement. Changes in these key inputs are not necessarily directly related. Changes in the fair value of MSRs are included in Net mortgage loan servicing fees in the consolidated statements of income.

MSRs are generally subject to loss in fair value when mortgage interest rates decrease. Decreasing mortgage interest rates normally encourage increased mortgage refinancing activity. Increased refinancing activity reduces the expected life of the underlying mortgage loans, thereby reducing the cash flows expected to accrue to the MSRs. Reductions in the fair value of MSRs affect income primarily through change in fair value and change in impairment. For MSRs backed by mortgage loans with historically low interest rates, factors other than interest rates (such as housing price changes) take on increasing influence on prepayment behavior of the underlying mortgage loans.

Following are the key inputs used in determining the fair value of MSRs at the time of initial recognition:

(1) The Company applies a pricing spread to the United States Dollar LIBOR curve for purposes of discounting cash flows relating to MSRs.

(2) For MSRs carried at fair value, an adverse change in one of the above-mentioned key inputs is expected to result in a reduction in fair value which will be recognized in income. For MSRs carried at lower of amortized cost or fair value, an adverse change in one of the above-mentioned key inputs may result in recognition of MSR impairment. The extent of the recognized MSR impairment will depend on the relationship of fair value to the carrying value of such MSRs.

(3) Prepayment speed is measured using Life Total CPR.

The preceding sensitivity analyses are limited in that they were performed at a particular point in time; only account for the estimated effect of the movements in the indicated inputs; do not incorporate changes in the inputs in relation to other inputs; are subject to the accuracy of various models and inputs used; and do not incorporate other factors that would affect the Company’s overall financial performance in such events, including operational adjustments made by the Manager to account for changing circumstances. For these reasons, the preceding estimates should not be viewed as earnings forecasts.

Securities Sold Under Agreements to Repurchase

Fair value of securities sold under agreements to repurchase is based on the accrued cost of the agreements, which approximates the fair values of the agreements, due to the short maturities of such agreements.

Derivative Instruments And Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Note 9—Derivative Financial Instruments

The Company’s activities involving derivative financial instruments are summarized below:

• The Company recognizes IRLCs in the normal course of business when it commits to purchase mortgage loans acquired for sale.

• The Company enters into CRT Agreements whereby it retains a Recourse Obligation relating to certain mortgage loans it sells into Fannie Mae guaranteed securitizations and an interest-only ownership interest in such mortgage loans. The fair values of the Recourse Obligations and the Company’s retention of the interest-only ownership interest are accounted for as derivative financial instruments.

• The Company engages in interest rate risk management activities in an effort to reduce the variability of earnings caused by the effects of changes in interest rates on the fair value of certain of its assets and liabilities. To manage the price risk resulting from interest rate risk, the Company uses derivative financial instruments acquired with the intention of moderating the risk that changes in market interest rates will result in unfavorable changes in the fair value of the Company’s MBS, inventory of mortgage loans acquired for sale, mortgage loans held in a VIE, ESS, IRLCs and MSRs.

The Company records all derivative financial instruments at fair value and records changes in fair value in current period income.

The Company is exposed to price risk relative to the IRLCs it issues to correspondent sellers and to the mortgage loans it purchases as a result of issuing the IRLCs. The Company bears price risk from the time an IRLC is issued to a correspondent seller to the time the purchased mortgage loan is sold. The Company is exposed to loss if market mortgage interest rates increase, because market interest rate increases generally cause the fair value of the IRLC or mortgage loan acquired for sale to decrease.

The Company had the following derivative assets and liabilities recorded within Derivative assets and Derivative liabilities and related margin deposits recorded in Other assets on the consolidated balance sheets:

Mortgage Loan Participation and Sale Agreements

Note 14—Mortgage Loan Participation and Sale Agreements

Certain borrowing facilities secured by mortgage loans acquired for sale are in the form of mortgage loan participation and sale agreements. Participation certificates, each of which represents an undivided beneficial ownership interest in a pool of mortgage loans that have been pooled with Fannie Mae or Freddie Mac, are sold to a lender pending the securitization of such mortgage loans and the sale of the resulting security. A commitment between the Company and a nonaffiliate to sell such security is also assigned to the lender at the time a participation certificate is sold.

The purchase price paid by the lender for each participation certificate is based on the trade price of the security, plus an amount of interest expected to accrue on the security to its anticipated delivery date, minus a present value adjustment, any related hedging costs and a holdback amount. The holdback amount is based on a percentage of the purchase price and is not required to be paid to the Company until the settlement of the security and its delivery to the lender.

Mortgage loan participation and sale agreements are summarized below:

	Quarter ended March 31,

Weighted-average interest rate (1)		2.08	%		1.68	%

Note 21—Shareholders’ Equity

Issuance of Preferred Shares of Beneficial Interest

On March 9, 2017, the Company issued 4,600,000 of its 8.125% Series A Fixed-to-Floating Rate Cumulative Redeemable Preferred Shares of Beneficial Interest, $0.01 par value per share (“Series A Preferred Shares”). From, and including, the date of original issuance to, but not including, March 15, 2024, the Company will pay cumulative dividends on the Series A Preferred Shares at a fixed rate of 8.125% per annum based on the $25.00 per share liquidation preference. From, and including, March 15, 2024 and thereafter, the Company will pay cumulative dividends on the Series A Preferred Shares at a floating rate equal to three-month LIBOR as calculated on each applicable dividend determination date plus a spread of 5.831% per annum based on the $25.00 per share liquidation preference. PMT will pay quarterly cumulative dividends on the Series A Preferred Shares, in arrears, on the 15th day of each March, June, September and December, beginning on June 15, 2017 (provided that if any dividend payment date is not a business day, then the dividend that would otherwise have been payable on that dividend payment date may be paid on the next succeeding business day).

The Series A Preferred Shares will not be redeemable before March 15, 2024, except in connection with the Company’s qualification as a REIT for U.S. federal income tax purposes or upon the occurrence of a change of control of the Company as described in the prospectus supplement filed with the SEC on March 6, 2017. On or after March 15, 2024 or within 120 days of the occurrence of a change in control, the Company may, at its option, redeem any or all of the Series A Preferred Shares at $25.00 per share plus any accumulated and unpaid dividends thereon to, but not including, the redemption date.

The Series A Preferred Shares have no stated maturity, are not subject to any sinking fund or mandatory redemption and will remain outstanding indefinitely unless redeemed or repurchased by the Company or converted into common shares of beneficial interest, $0.01 par value per share, of PMT in connection with a change of control by the holders of the Series A Preferred Shares.

Common Share Repurchases

During August 2015, the Company’s board of trustees authorized a common share repurchase program under which the Company may repurchase up to $150 million of its outstanding common shares. During February 2016, the Company’s board of trustees approved an increase to its share repurchase program pursuant to which the Company is now authorized to repurchase up to $200 million of its common shares.

The following table summarizes the Company’s share repurchase activity:

	Quarter ended March 31,
	2017		2016		Cumulative Total (1)
	(in thousands)
Common shares repurchased		139		5,156		8,552

(1) Amounts represent the share repurchase program total from its inception in August 2015 through March 31, 2017.

The repurchased common shares were canceled upon settlement of the repurchase transactions and returned to the authorized but unissued common share pool.

Conditional Reimbursement of IPO Underwriting Costs

As more fully described in Note 3—Transactions with Related Parties, on February 1, 2013, the Company entered into a Reimbursement Agreement, by and among the Company, the Operating Partnership and PCM. The Reimbursement Agreement provides that, to the extent the Company is required to pay PCM performance incentive fees under the management agreement, the Company will reimburse PCM for underwriting costs it paid on the IPO offering date at a rate of $10 in reimbursement for every $100 of performance incentive fees earned. The reimbursement is subject to a maximum reimbursement in any particular 12-month period of $1.0 million, and the maximum amount that may be reimbursed under the agreement is $2.9 million. No payments were made during the quarters ended March 31, 2017 and March 31, 2016.

The Reimbursement Agreement also provides for the payment to the IPO underwriters of the amount that the Company agreed to pay to them at the time of the IPO if the Company satisfied certain performance measures over a specified period of time. As PCM earns performance incentive fees under the management agreement, the IPO underwriters will be paid at a rate of $20 of payments for every $100 of performance incentive fees earned by PCM. The payment to the underwriters is subject to a maximum reimbursement in any particular 12-month period of $2.0 million and the maximum amount that may be paid under the agreement is $5.9 million. No payments were made during the quarters ended March 31, 2017 and March 31, 2016. The Reimbursement Agreement expires on February 1, 2019.

Note 28—Income Taxes

The Company’s effective tax rate was (27.1)% and (31.3)% for the quarters ended March 31, 2017 and 2016, respectively. The Company’s taxable REIT subsidiary recognized a tax benefit of $6.6 million on a loss of $14.8 million while the Company’s reported consolidated pretax income was $22.6 million for the quarter ended March 31, 2017. For the same period in 2016, the Company’s taxable REIT subsidiary recognized a tax benefit of $3.5 million on a loss of $6.0 million while the Company’s reported consolidated pretax income was $11.0 million. The relative values between the tax benefit at the taxable REIT subsidiary and the Company’s consolidated pretax income drive the fluctuation in the effective tax rate. The primary difference between the Company’s effective tax rate and the statutory tax rate is due to non-taxable REIT income resulting from the dividends paid deduction.

In general, cash dividends declared by the Company will be considered ordinary income to shareholders for income tax purposes. Some portion of the dividends may be characterized as capital gain distributions or a return of capital.

Segment Reporting [Abstract]

Segments and Related Information

Note 29—Segments and Related Information

During the quarter ended March 31, 2017, the Company changed the composition of its operating segments. The reporting used by the Company’s chief operating decision maker changed as the Company’s investment activities have become more diversified. The Manager has focused this broadened investment base on two classes of investments: credit sensitive and interest rate sensitive mortgage related assets.  As this focus has developed, the Manager’s reporting on and management of the Company’s investments has also developed along these lines.  Accordingly, during the quarter ended March 31, 2017, management re-evaluated this new information in relation to its definition of its operating segments.

The Company has redefined its segment reporting to separately distinguish its investment activities between credit sensitive and interest rate sensitive investments and certain corporate activities.

Credit sensitive investment strategies include investments in distressed mortgage loans, REO, CRT Agreements, non-Agency subordinated bonds and small balance commercial real estate mortgage loans. Interest rate sensitive strategies include investments in MSRs, ESS, Agency and senior non-Agency MBS and the related interest rate hedging activities.  The corporate segment includes certain interest income, management fee and corporate expense amounts.

Segment results for the quarter ended March 31, 2016 have been restated to conform prior year presentation to the new segment composition.

Accounting Changes And Error Corrections [Abstract]

Recently Issued Accounting Pronouncements

Note 32—Recently Issued Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Subtopic 606) (“ASU 2014-09”), which supersedes the guidance in the Revenue Recognition topic of the ASC. ASU 2014-09 clarifies the principles for recognizing revenue in order to improve comparability of revenue recognition practices across entities and industries with certain scope exceptions including financial instruments, leases, and guarantees. ASU 2014-09 provides guidance intended to assist in the identification of contracts with customers and separate performance obligations within those contracts, the determination and allocation of the transaction price to those identified performance obligations and the recognition of revenue when a performance obligation has been satisfied. ASU 2014-09 also requires disclosures regarding the nature, amount, timing, and uncertainty of revenues and cash flows from contracts with customers.

Upon adoption, ASU 2014-09 provides for transition through either a full retrospective approach requiring the restatement of all presented prior periods or a modified retrospective approach, which allows the new recognition standard to be applied to only those contracts that are not completed at the date of transition. If the modified retrospective approach is adopted, a cumulative-effect adjustment to retained earnings is performed with additional disclosures required including the amount by which each line item is affected by the transition as compared to the guidance in effect before adoption and an explanation of the reasons for significant changes in these amounts.

The FASB has issued several amendments to ASU 2014-09, including:

• In August 2015, ASU 2015-14, Revenue From Contracts With Customers (“ASU 2015-14”). This update deferred the initial effective date of ASU 2014-09. As a result of the issuance of ASU 2015-14, ASU 2014-09 is effective for annual reporting periods beginning on or after December 15, 2017, and interim periods within those annual periods. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period.

• In March 2016, ASU 2016-08, Principal Versus Agent Considerations (Reporting Revenue Gross versus Net). The amendments to this update are intended to improve the implementation guidance on principal versus agent considerations in ASU 2014-09 by clarifying how an entity should identify the unit of accounting (i.e. the specified good or service) and how an entity should apply the control principle to certain types of arrangements.

• In May 2016, ASU 2016-12, Narrow-Scope Improvements and Practical Expedients. The amendments to this update clarify certain core recognition principles and provide practical expedients available at transition. The improvements address collectability, sales tax presentation, noncash consideration, contract modifications and completed contracts at transition.

• In December 2016, ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers. The amendments to this update:

o Clarify that guarantee fees within the scope of the Guarantees topic of the ASC (other than product or service warranties) are not within the scope of the Revenue from Contracts with Customers topic of the ASC. Entities should see the Derivatives and Hedging topic of the ASC, for guarantees accounted for as derivatives.

o Clarify the Other Assets and Deferred Costs—Contracts with Customers subtopic of the ASC that when performing impairment testing an entity should (a) consider expected contract renewals and extensions and (b) include both the amount of consideration it already has received but has not recognized as revenue and the amount it expects to receive in the future.

o Clarify the interaction of impairment testing with guidance in other ASC topics that impairment testing first should be performed on assets not within the scope of the Other Assets and Deferred Costs, Intangibles-Goodwill and Other and the Property, Plant, and Equipment topics (such as assets within the Inventory topic of the ASC), then assets within the scope of the Other Assets and Deferred Costs topic of the ASC, then asset groups and reporting units within the scope of the Other Assets and Deferred Costs, Intangibles-Goodwill and Other and the Property, Plant, and Equipment topics of the ASC.

o Clarify that all contracts within the scope of the Financial Services – Insurance topic of the ASC are excluded from the scope of the Revenue from Contracts with Customers topic.

o Provide optional exemptions from the disclosure requirement for remaining performance obligations for specific situations in which an entity need not estimate variable consideration to recognize revenue and expands the information that is required to be disclosed when an entity applies one of the optional exemptions.

o Clarify that the disclosure of revenue recognized from performance obligations satisfied (or partially satisfied) in previous periods applies to all performance obligations and is not limited to performance obligations with corresponding contract balances.

• In February 2017, ASU 2017-05, Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) (“ASU 2017-05”). The amendments to this update clarify the scope of the Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets subtopic of the ASC, and to add guidance for partial sales of nonfinancial assets. ASU 2017-05 clarifies that:

o A financial asset is within the scope of the Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets subtopic of the ASC if it meets the definition of an in substance nonfinancial asset and defines the term in substance nonfinancial asset, in part, as a financial asset promised to a counterparty in a contract if substantially all of the fair value of the assets (recognized and unrecognized) that are promised to the counterparty in the contract is concentrated in nonfinancial assets.

o It excludes all businesses and nonprofit activities from the scope of the Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets subtopic of the ASC. Derecognition of all businesses and nonprofit activities should be accounted for in accordance with the Consolidation—Overall subtopic of the ASC.

o An entity should identify each distinct nonfinancial asset or in substance nonfinancial asset promised to a counterparty and derecognize each asset when a counterparty obtains control of it.

o An entity should allocate consideration to each distinct asset by applying the guidance in the Revenue from Contracts with Customers topic of the ASC on allocating the transaction price to performance obligations.

o An entity must derecognize a distinct nonfinancial asset or distinct in substance nonfinancial asset in a partial sale transaction when it (1) does not have (or ceases to have) a controlling financial interest in the legal entity that holds the asset in accordance with the Consolidations topic and (2) transfers control of the asset in accordance with the Revenue from Contracts with Customers topic of the ASC. Once an entity transfers control of a distinct nonfinancial asset or distinct in substance nonfinancial asset, it is required to measure any noncontrolling interest it receives (or retains) at fair value.

The Manager is currently evaluating the pending adoption of ASU 2014-09 and its amendments and their impact on the consolidated financial statements. The Manager does not expect the adoption of ASU 2014-09 to have a significant effect on the consolidated financial statements of the Company and has not yet identified which transition method will be applied upon adoption.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments–Overall: Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). ASU 2016-01 affects the accounting for equity investments, financial liabilities under the fair value option, the presentation and disclosure requirements for financial instruments, and the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities.

ASU 2016-01 requires that:

• All equity investments in unconsolidated entities (other than those accounted for using the equity method of accounting) with readily determinable fair values will generally be measured at fair value through earnings.

• When the fair value option has been elected for financial liabilities, changes in fair value due to instrument-specific credit risk will be recognized separately in other comprehensive income. The accumulated gains and losses due to these changes will be reclassified from accumulated other comprehensive income to earnings if the financial liability is settled before maturity.

• For financial instruments measured at amortized cost, public business entities will be required to use the exit price when measuring the fair value of financial instruments for disclosure purposes.

• Financial assets and financial liabilities shall be presented separately in the notes to the financial statements, grouped by measurement category (e.g., fair value, amortized cost, lower of cost or fair value) and form of financial asset (e.g., loans, securities).

• Public business entities will no longer be required to disclose the methods and significant assumptions used to estimate the fair value of financial instruments carried at amortized cost.

• Entities will have to assess the realizability of a deferred tax asset related to a debt security classified as available for sale in combination with the entity’s other deferred tax assets.

The classification and measurement guidance will be effective for public business entities in fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption of the provision to record fair value changes for financial liabilities under the fair value option resulting from instrument-specific credit risk in other comprehensive income is permitted and can be elected for all financial statements of fiscal years and interim periods that have not yet been issued or that have not yet been made available for issuance. The Manager does not believe that the adoption of ASU 2016-01 will have a significant effect on its consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). ASU 2016-09 simplifies several aspects of the accounting for share-based payment award transactions, including:

• Modifies the accounting for income taxes relating to share-based payments. All excess tax benefits and tax deficiencies (including tax benefits of dividends on share-based payment awards) will be recognized as income tax expense or benefit in the consolidated statement of income. The tax effects of exercised or vested awards will be treated as discrete items in the reporting period in which they occur. An entity will recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period. Under current GAAP, excess tax benefits are recognized in additional paid-in capital; tax deficiencies are recognized either as an offset to accumulated excess tax benefits, if any, or in the consolidated statement of income in the period they reduce income taxes payable.

• Changes the classification of excess tax benefits on the consolidated statement of cash flows. In the consolidated statement of cash flows, excess tax benefits will be classified along with other income tax cash flows as an operating activity. Under current GAAP, excess tax benefits are separated from other income tax cash flows and classified as a financing activity.

• Changes the requirement to estimate the number of awards that are expected to vest. Under ASC 2016-09, an entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest as presently required or account for forfeitures when they occur. Under current GAAP, accruals of compensation cost are based on the number of awards that are expected to vest.

• Changes the tax withholding requirements for share-based payment awards to qualify for equity accounting. The threshold to qualify for equity classification permits withholding up to the maximum statutory tax rates in the applicable jurisdictions. Under current GAAP, for an award to qualify for equity classification is that an entity cannot partially settle the award in cash in excess of the employer’s minimum statutory withholding requirements.

• Establishes GAAP for the classification of employee taxes paid when an employer withholds shares for tax withholding purposes. Cash paid by an employer when directly withholding shares for tax- withholding purposes should be classified as a financing activity. This guidance establishes GAAP related to the classification of withholding taxes in the statement of cash flows as there is no such guidance under current GAAP.

ASU 2016-09 is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any organization in any interim or annual period. The adoption ASU 2016-09 did not have a significant effect on the Company’s consolidated financial statements.

Subsequent Events

Note 33—Subsequent Events

Management has evaluated all events and transactions through the date the Company issued these consolidated financial statements. During this period:

• On April 28, 2017, the Company, through POP, PMC, PMH and PMC REO Financing Trust, LLC (“REO Subsidiary”), entered into a Second Amended and Restated Master Repurchase Agreement with CSFB, as administrative agent to the buyers, Credit Suisse AG, Cayman Islands Branch, as a buyer (“CS Cayman”), and Alpine Securitization LTD, as a buyer (“Alpine” and, together with CS Cayman, the “CS Buyers”)(the “CS Repurchase Agreement”), pursuant to which POP, PMC and/or PMH, as applicable, finance (i) newly originated mortgage loans that PMC purchases from correspondent lenders pending sale and/or securitization, and (ii) distressed mortgage loans and equity interests in REO Subsidiary owning real estate acquired upon settlement of mortgage loans (the “REO Properties”).

The maximum combined purchase price under the CS Repurchase Agreement, together with the Re-warehouse Facility (as defined below), was increased in connection with the amendment and restatement to $1.5 billion. The maximum combined committed purchase price is $650 million, all of which is committed and available for purchases under the CS Repurchase Agreement to the extent not reduced by purchased amounts outstanding under the Re-warehouse Facility and two other master repurchase agreements entered into by the Company in the ordinary course of its business to finance asset-backed securities with CS Cayman and one of its affiliates.

• On April 28, 2017, the Company, through POP, also entered into a Second Amended and Restated Master Repurchase Agreement with CSFB, as administrative agent, and CS Buyers, pursuant to which POP may sell to CS Buyers, and later repurchase, newly originated mortgage loans for which POP provides financing to third-party mortgage loan originators (the “Re-warehouse Facility”). The maximum combined purchase price under the Re-warehouse Facility, together with the CS Repurchase Agreement, was increased in connection with the amendment and restatement to $1.5 billion. The maximum combined committed purchase price is $650 million, and the committed amount under the Re-warehouse Facility is equal to the lesser of (a) $300 million and (b) the maximum combined committed purchase price less all purchased amounts outstanding under the CS Repurchase Agreement.

• On May 3, 2017, the Company, through PMC, entered into an amendment (the “Repurchase Amendment”) to its Master Repurchase Agreement, dated as of September 14, 2015, by and among Barclays, PMC, PLS and the Company (the “Barclays Repurchase Agreement”), pursuant to which PMC finances newly originated mortgage loans. Under the terms of the Repurchase Amendment, the maximum aggregate purchase price provided for in the Repurchase Agreement was temporarily increased from $400 million to $600 million, the available amount of which is reduced by any outstanding purchase amounts under the Participation Agreement (as defined below) and any borrowed amounts under a loan and security agreement by and among PMC, the Company and Barclays dated September 14, 2015. The period of the increase runs from May 15, 2017 to and including September 30, 2017.

• On May 3, 2017, the Company, through PMC, also entered into an amendment (the “Participation Amendment) to its Mortgage Loan Participation Purchase and Sale Agreement, dated as of September 14, 2015, by and among Barclays, PMC and PLS (the “Participation Agreement”), pursuant to which PMC may sell to Barclays participation certificates, each of which represents an undivided beneficial ownership interest in a pool of mortgage loans that have been pooled with Fannie Mae or Freddie Mac and are pending securitization. Under the terms of the Participation Amendment, the maximum aggregate purchase price provided for in the Participation Agreement was temporarily increased from $400 million to $600 million, the available amount of which is reduced by any outstanding repurchase amounts under the Barclays Repurchase Agreement and any borrowed amounts under a loan and security agreement by and among PMC, the Company and Barclays dated September 14, 2015. The period of the increase runs from May 15, 2017 to and including September 30, 2017.

Organization and Basis of Presentation (Policies)

Organization Consolidation And Presentation Of Financial Statements [Abstract]

Segment Reporting

The Company operates in four segments: correspondent production, credit sensitive strategies, interest rate sensitive strategies and corporate:

• The correspondent production segment represents the Company’s operations aimed at serving as an intermediary between mortgage lenders and the capital markets by purchasing, pooling and reselling newly originated prime credit quality mortgage loans either directly or in the form of mortgage-backed securities (“MBS”), using the services of PNMAC Capital Management, LLC (“PCM” or the “Manager”) and PennyMac Loan Services, LLC (“PLS”), both indirect controlled subsidiaries of PennyMac Financial Services, Inc. (“PFSI”).

Most of the mortgage loans the Company has acquired in its correspondent production activities have been eligible for sale to government-sponsored entities such as the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”) or through government agencies such as the Government National Mortgage Association (“Ginnie Mae”). Fannie Mae, Freddie Mac and Ginnie Mae are each referred to as an “Agency” and, collectively, as the “Agencies.”

• The credit sensitive strategies segment represents the Company’s investments in distressed mortgage loans, real estate acquired in settlement of mortgage loans (“REO”), credit risk transfer agreements (“CRT Agreements”), non-Agency subordinated bonds and small balance commercial real estate mortgage loans.

• The interest rate sensitive strategies segment represents the Company’s investments in mortgage servicing rights (“MSRs”), excess servicing spread (“ESS”), Agency and senior non-Agency MBS and the related interest rate hedging activities.  

• The corporate segment includes certain interest income, management fee and corporate expense amounts.

Basis of Accounting

The Company conducts substantially all of its operations and makes substantially all of its investments through its subsidiary, PennyMac Operating Partnership, L.P. (the “Operating Partnership”), and the Operating Partnership’s subsidiaries. A wholly-owned subsidiary of the Company is the sole general partner, and the Company is the sole limited partner, of the Operating Partnership.

The accompanying consolidated financial statements have been prepared in compliance with accounting principles generally accepted in the United States (“GAAP”) as codified in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) for interim financial information and with the Securities and Exchange Commission’s instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, these financial statements and notes do not include all of the information required by GAAP for complete financial statements. The interim consolidated information should be read together with the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

The accompanying unaudited consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, but are not necessarily indicative of the results of operations that may be anticipated for the full year. Intercompany accounts and transactions have been eliminated.

Concentration Risk

Due to the nature of the Company’s investments, PMT is exposed, to a greater extent than traditional mortgage investors, to the risks associated with loan resolution, including that borrowers may be in economic distress and/or may have become unemployed, bankrupt or otherwise unable or unwilling to make payments when due, and that fluctuations in the residential real estate market may affect the performance of its investments. Factors influencing these risks include, but are not limited to:

• changes in the overall economy, unemployment rates and residential real estate values in the markets where the properties securing the Company’s mortgage loans are located;

• PCM’s ability to identify and PLS’ ability to execute optimal resolutions of certain mortgage loans;

• the accuracy of valuation information obtained during the Company’s due diligence activities;

• PCM’s ability to effectively model, and to develop appropriate model inputs that properly anticipate, future outcomes;

• the level of government support for resolution of certain mortgage loans and the effect of current and future proposed and enacted legislative and regulatory changes on the Company’s ability to effect cures or resolutions to distressed mortgage loans; and

• regulatory, judicial and legislative support of the foreclosure process, and the resulting effect on the Company’s ability to acquire and liquidate the real estate securing its portfolio of distressed mortgage loans in a timely manner or at all.

Due to these uncertainties, there can be no assurance that risk management activities identified and executed on PMT’s behalf will prevent significant losses arising from the Company’s investments in real estate-related assets.

Earnings Per Share

The Company grants restricted share units which entitle the recipients to receive dividend equivalents during the vesting period on a basis equivalent to the dividends paid to holders of common shares. Unvested share-based compensation awards containing non-forfeitable rights to receive dividends or dividend equivalents (collectively, “dividends”) are classified as “participating securities” and are included in the basic earnings per share calculation using the two-class method.

Under the two-class method, all earnings (distributed and undistributed) are allocated to common shares and participating securities, based on their respective rights to receive dividends. Basic earnings per share is determined by dividing net income, reduced by income attributable to the participating securities, by the weighted-average common shares outstanding during the period.

Diluted earnings per share is determined by dividing net income attributable to diluted shareholders, which adds back to net income the interest expense, net of applicable income taxes, on the Company’s exchangeable senior notes (the “Exchangeable Notes”), by the weighted-average common shares outstanding, assuming all dilutive securities were issued. In periods in which the Company records a loss, potentially dilutive securities are excluded from the diluted loss per share calculation, as their effect on loss per share is anti-dilutive.

Fair Value Measurement

The Company’s consolidated financial statements include assets and liabilities that are measured based on their fair values. Measurement at fair value may be on a recurring or nonrecurring basis depending on the accounting principles applicable to the specific asset or liability and whether the Manager has elected to carry the item at its fair value as discussed in the following paragraphs.

The Company groups its assets and liabilities at fair value in three levels, based on the markets in which the assets and liabilities are traded and the observability of the inputs used to determine fair value. These levels are:

• Level 1—Quoted prices in active markets for identical assets or liabilities.

• Level 2—Prices determined or determinable using other significant observable inputs. Observable inputs are inputs that other market participants would use in pricing the asset or liability and are developed based on market data obtained from sources independent of the Company. These may include quoted prices for similar assets or liabilities, interest rates, prepayment speeds, credit risk and other inputs.

• Level 3—Prices determined using significant unobservable inputs. In situations where significant observable inputs are unavailable unobservable inputs may be used. Unobservable inputs reflect the Company’s own judgments about the factors that market participants use in pricing assets and liabilities, and are based on the best information available in the circumstances.

As a result of the difficulty in observing certain significant valuation inputs affecting “Level 3” fair value assets and liabilities, the Manager is required to make judgments regarding these items’ fair values. Different persons in possession of the same facts may reasonably arrive at different conclusions as to the inputs to be applied in valuing these assets and liabilities and to their fair values. Likewise, due to the general illiquidity of some of these assets and liabilities, subsequent transactions may be at values significantly different from those reported.

Fair Value Accounting Elections

The Manager identified all of the Company’s non-cash financial assets and MSRs relating to non-commercial real estate secured mortgage loans with initial interest rates of more than 4.5%, to be accounted for at fair value. The Manager has elected to account for these assets at fair value so such changes in fair value will be reflected in income as they occur and more timely reflect the results of the Company’s performance.

The Manager has also identified the Company’s asset-backed financing of a VIE and interest only security payable at fair value to be accounted for at fair value to reflect the generally offsetting changes in fair value of these borrowings to changes in fair value of mortgage loans at fair value or other assets collateralizing these financings. For other borrowings, the Manager has determined that historical cost accounting is more appropriate because under this method debt issuance costs are amortized over the term of the debt, thereby matching the debt issuance cost to the periods benefiting from the availability of the debt.

Recently Issued Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Subtopic 606) (“ASU 2014-09”), which supersedes the guidance in the Revenue Recognition topic of the ASC. ASU 2014-09 clarifies the principles for recognizing revenue in order to improve comparability of revenue recognition practices across entities and industries with certain scope exceptions including financial instruments, leases, and guarantees. ASU 2014-09 provides guidance intended to assist in the identification of contracts with customers and separate performance obligations within those contracts, the determination and allocation of the transaction price to those identified performance obligations and the recognition of revenue when a performance obligation has been satisfied. ASU 2014-09 also requires disclosures regarding the nature, amount, timing, and uncertainty of revenues and cash flows from contracts with customers.

Upon adoption, ASU 2014-09 provides for transition through either a full retrospective approach requiring the restatement of all presented prior periods or a modified retrospective approach, which allows the new recognition standard to be applied to only those contracts that are not completed at the date of transition. If the modified retrospective approach is adopted, a cumulative-effect adjustment to retained earnings is performed with additional disclosures required including the amount by which each line item is affected by the transition as compared to the guidance in effect before adoption and an explanation of the reasons for significant changes in these amounts.

The FASB has issued several amendments to ASU 2014-09, including:

• In August 2015, ASU 2015-14, Revenue From Contracts With Customers (“ASU 2015-14”). This update deferred the initial effective date of ASU 2014-09. As a result of the issuance of ASU 2015-14, ASU 2014-09 is effective for annual reporting periods beginning on or after December 15, 2017, and interim periods within those annual periods. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period.

• In March 2016, ASU 2016-08, Principal Versus Agent Considerations (Reporting Revenue Gross versus Net). The amendments to this update are intended to improve the implementation guidance on principal versus agent considerations in ASU 2014-09 by clarifying how an entity should identify the unit of accounting (i.e. the specified good or service) and how an entity should apply the control principle to certain types of arrangements.

• In May 2016, ASU 2016-12, Narrow-Scope Improvements and Practical Expedients. The amendments to this update clarify certain core recognition principles and provide practical expedients available at transition. The improvements address collectability, sales tax presentation, noncash consideration, contract modifications and completed contracts at transition.

• In December 2016, ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers. The amendments to this update:

o Clarify that guarantee fees within the scope of the Guarantees topic of the ASC (other than product or service warranties) are not within the scope of the Revenue from Contracts with Customers topic of the ASC. Entities should see the Derivatives and Hedging topic of the ASC, for guarantees accounted for as derivatives.

o Clarify the Other Assets and Deferred Costs—Contracts with Customers subtopic of the ASC that when performing impairment testing an entity should (a) consider expected contract renewals and extensions and (b) include both the amount of consideration it already has received but has not recognized as revenue and the amount it expects to receive in the future.

o Clarify the interaction of impairment testing with guidance in other ASC topics that impairment testing first should be performed on assets not within the scope of the Other Assets and Deferred Costs, Intangibles-Goodwill and Other and the Property, Plant, and Equipment topics (such as assets within the Inventory topic of the ASC), then assets within the scope of the Other Assets and Deferred Costs topic of the ASC, then asset groups and reporting units within the scope of the Other Assets and Deferred Costs, Intangibles-Goodwill and Other and the Property, Plant, and Equipment topics of the ASC.

o Clarify that all contracts within the scope of the Financial Services – Insurance topic of the ASC are excluded from the scope of the Revenue from Contracts with Customers topic.

o Provide optional exemptions from the disclosure requirement for remaining performance obligations for specific situations in which an entity need not estimate variable consideration to recognize revenue and expands the information that is required to be disclosed when an entity applies one of the optional exemptions.

o Clarify that the disclosure of revenue recognized from performance obligations satisfied (or partially satisfied) in previous periods applies to all performance obligations and is not limited to performance obligations with corresponding contract balances.

• In February 2017, ASU 2017-05, Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) (“ASU 2017-05”). The amendments to this update clarify the scope of the Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets subtopic of the ASC, and to add guidance for partial sales of nonfinancial assets. ASU 2017-05 clarifies that:

o A financial asset is within the scope of the Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets subtopic of the ASC if it meets the definition of an in substance nonfinancial asset and defines the term in substance nonfinancial asset, in part, as a financial asset promised to a counterparty in a contract if substantially all of the fair value of the assets (recognized and unrecognized) that are promised to the counterparty in the contract is concentrated in nonfinancial assets.

o It excludes all businesses and nonprofit activities from the scope of the Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets subtopic of the ASC. Derecognition of all businesses and nonprofit activities should be accounted for in accordance with the Consolidation—Overall subtopic of the ASC.

o An entity should identify each distinct nonfinancial asset or in substance nonfinancial asset promised to a counterparty and derecognize each asset when a counterparty obtains control of it.

o An entity should allocate consideration to each distinct asset by applying the guidance in the Revenue from Contracts with Customers topic of the ASC on allocating the transaction price to performance obligations.

o An entity must derecognize a distinct nonfinancial asset or distinct in substance nonfinancial asset in a partial sale transaction when it (1) does not have (or ceases to have) a controlling financial interest in the legal entity that holds the asset in accordance with the Consolidations topic and (2) transfers control of the asset in accordance with the Revenue from Contracts with Customers topic of the ASC. Once an entity transfers control of a distinct nonfinancial asset or distinct in substance nonfinancial asset, it is required to measure any noncontrolling interest it receives (or retains) at fair value.

The Manager is currently evaluating the pending adoption of ASU 2014-09 and its amendments and their impact on the consolidated financial statements. The Manager does not expect the adoption of ASU 2014-09 to have a significant effect on the consolidated financial statements of the Company and has not yet identified which transition method will be applied upon adoption.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments–Overall: Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). ASU 2016-01 affects the accounting for equity investments, financial liabilities under the fair value option, the presentation and disclosure requirements for financial instruments, and the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities.

ASU 2016-01 requires that:

• All equity investments in unconsolidated entities (other than those accounted for using the equity method of accounting) with readily determinable fair values will generally be measured at fair value through earnings.

• When the fair value option has been elected for financial liabilities, changes in fair value due to instrument-specific credit risk will be recognized separately in other comprehensive income. The accumulated gains and losses due to these changes will be reclassified from accumulated other comprehensive income to earnings if the financial liability is settled before maturity.

• For financial instruments measured at amortized cost, public business entities will be required to use the exit price when measuring the fair value of financial instruments for disclosure purposes.

• Financial assets and financial liabilities shall be presented separately in the notes to the financial statements, grouped by measurement category (e.g., fair value, amortized cost, lower of cost or fair value) and form of financial asset (e.g., loans, securities).

• Public business entities will no longer be required to disclose the methods and significant assumptions used to estimate the fair value of financial instruments carried at amortized cost.

• Entities will have to assess the realizability of a deferred tax asset related to a debt security classified as available for sale in combination with the entity’s other deferred tax assets.

The classification and measurement guidance will be effective for public business entities in fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption of the provision to record fair value changes for financial liabilities under the fair value option resulting from instrument-specific credit risk in other comprehensive income is permitted and can be elected for all financial statements of fiscal years and interim periods that have not yet been issued or that have not yet been made available for issuance. The Manager does not believe that the adoption of ASU 2016-01 will have a significant effect on its consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). ASU 2016-09 simplifies several aspects of the accounting for share-based payment award transactions, including:

• Modifies the accounting for income taxes relating to share-based payments. All excess tax benefits and tax deficiencies (including tax benefits of dividends on share-based payment awards) will be recognized as income tax expense or benefit in the consolidated statement of income. The tax effects of exercised or vested awards will be treated as discrete items in the reporting period in which they occur. An entity will recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period. Under current GAAP, excess tax benefits are recognized in additional paid-in capital; tax deficiencies are recognized either as an offset to accumulated excess tax benefits, if any, or in the consolidated statement of income in the period they reduce income taxes payable.

• Changes the classification of excess tax benefits on the consolidated statement of cash flows. In the consolidated statement of cash flows, excess tax benefits will be classified along with other income tax cash flows as an operating activity. Under current GAAP, excess tax benefits are separated from other income tax cash flows and classified as a financing activity.

• Changes the requirement to estimate the number of awards that are expected to vest. Under ASC 2016-09, an entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest as presently required or account for forfeitures when they occur. Under current GAAP, accruals of compensation cost are based on the number of awards that are expected to vest.

• Changes the tax withholding requirements for share-based payment awards to qualify for equity accounting. The threshold to qualify for equity classification permits withholding up to the maximum statutory tax rates in the applicable jurisdictions. Under current GAAP, for an award to qualify for equity classification is that an entity cannot partially settle the award in cash in excess of the employer’s minimum statutory withholding requirements.

• Establishes GAAP for the classification of employee taxes paid when an employer withholds shares for tax withholding purposes. Cash paid by an employer when directly withholding shares for tax- withholding purposes should be classified as a financing activity. This guidance establishes GAAP related to the classification of withholding taxes in the statement of cash flows as there is no such guidance under current GAAP.

ASU 2016-09 is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any organization in any interim or annual period. The adoption ASU 2016-09 did not have a significant effect on the Company’s consolidated financial statements.

Summary of Credit Risk Transfer Agreements

The Company, through its wholly-owned subsidiary, PennyMac Corp. (“PMC”), entered into CRT Agreements with Fannie Mae, pursuant to which PMC, through subsidiary trust entities, sells pools of mortgage loans into Fannie Mae-guaranteed securitizations while retaining a portion of the credit risk underlying such mortgage loans (“Recourse Obligations”) as part of the retention of an interest-only ownership interest in such mortgage loans.  The mortgage loans subject to the CRT Agreements are transferred by PMC to subsidiary trust entities which sell the mortgage loans into Fannie Mae mortgage loan securitizations. Transfers of mortgage loans subject to CRT Agreements receive sale accounting treatment upon fulfillment of the criteria for sale recognition contained in the Transfers and Servicing topic of the ASC. The pledged cash represents the Company’s maximum contractual exposure to claims under its Recourse Obligations and is the sole source of settlement of losses under the CRT Agreements. Gains and losses on net derivatives related to CRT Agreements are included in Net gain on investments in the consolidated statements of income.

(1) The Company applies a pricing spread to the United States Dollar LIBOR curve for purposes of discounting cash flows relating to MSRs.

(2) For MSRs carried at fair value, an adverse change in one of the above-mentioned key inputs is expected to result in a reduction in fair value which will be recognized in income. For MSRs carried at lower of amortized cost or fair value, an adverse change in one of the above-mentioned key inputs may result in recognition of MSR impairment. The extent of the recognized MSR impairment will depend on the relationship of fair value to the carrying value of such MSRs.

(3) Prepayment speed is measured using Life Total CPR.
