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 loans and mortgage-related assets. The Company operates in two segments, correspondent production and investment activities: • 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 (“PCM” or the “Manager”) and PennyMac Loan Services, LLC (“PLS” or the “Servicer”), both indirect 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 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 investment activities segment represents the Company’s investments in mortgage-related assets, which include distressed mortgage loans, real estate acquired in settlement of loans (“REO”), MBS, mortgage servicing rights (“MSRs”) and excess servicing spread (“ESS”). The Company seeks to maximize the fair value of its acquired distressed mortgage loans through proprietary loan modification programs, special servicing or other initiatives focused on keeping borrowers in their homes. Where this is not possible, such as in the case of many nonperforming mortgage loans, the Company seeks to effect property resolution in a timely, orderly and economically efficient manner, including through the use of resolution alternatives to foreclosure. 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 (the “Internal Revenue Code”), 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 The accompanying unaudited consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, income, and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year ending December 31, 2015. Intercompany accounts and transactions have been eliminated. Preparation of financial statements in compliance with GAAP requires management to make estimates and assumptions 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. Reclassification of previously presented balances In April of 2015, the FASB issued Accounting Standards Update (“ASU”) No. 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs Other assets Mortgage loans sold under agreements to repurchase Following is a summary of the balance sheet reclassifications: December 31, 2014 As reported As previously reported Reclassification (in thousands) ASSETS Other assets $ 59,155 $ 66,193 $ (7,038 ) Total assets $ 4,897,258 $ 4,904,296 $ (7,038 ) LIABILITIES Assets sold under agreements to repurchase $ 2,729,027 $ 2,730,130 $ (1,103 ) Mortgage loan participation and sale agreement 20,222 20,236 (14 ) Exchangeable senior notes 244,079 250,000 (5,921 ) Total liabilities 3,319,086 3,326,124 (7,038 ) Total liabilities and shareholders’ equity $ 4,897,258 $ 4,904,296 $ (7,038 )

Risks and Uncertainties [Abstract]
Concentration of Risks	Note 2—Concentration of Risks As discussed in Note 1— Organization and Basis of Presentation Because of the Company’s investment focus, PMT is exposed, to a greater extent than traditional mortgage investors, to the risks 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 to the effects of fluctuations in the residential real estate market on the performance of its investments. Factors influencing these risks include, but are not limited to: • changes in the overall economy and 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 the Servicer’s ability to execute optimal resolutions of problem 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 assumptions that properly anticipate, future outcomes; • the level of government support for problem mortgage loan resolution 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 purchased by the Company in prior years has been acquired from or through one or more subsidiaries of Citigroup Inc. The following tables present purchases for the Company’s investment portfolio of mortgage loans and REO (including purchases under forward purchase agreements), and the portion thereof representing assets purchased from or through one or more subsidiaries of Citigroup Inc.: Quarter ended June 30, Six months ended June 30, 2015 2014 2015 2014 (in thousands) Investment portfolio purchases: Mortgage loans $ — $ 27,203 $ 241,981 $ 284,403 REO — 30 — 3,117 $ — $ 27,233 $ 241,981 $ 287,520 Investment portfolio purchases above through one or more subsidiaries of Citigroup Inc.: Mortgage loans $ — $ 26,737 $ — $ 26,737 REO — 30 — 68 $ — $ 26,767 $ — $ 26,805 Following is a summary of the Company’s holdings of assets purchased through one or more subsidiaries of Citigroup Inc.: June 30, December 31, (in thousands) Mortgage loans at fair value $ 882,881 $ 943,163 REO 93,171 108,302 $ 976,052 $ 1,051,465 Total holdings of mortgage loans and REO $ 3,055,098 $ 3,030,180 During the year ended December 31, 2013, the Company entered into forward purchase agreements with Citigroup Global Markets Realty Corp. (“CGM”), a subsidiary of Citigroup Inc., to purchase certain nonperforming mortgage loans and REO (collectively, the “CGM Assets”). The CGM Assets were acquired by CGM from unaffiliated money center banks and were held in a trust subsidiary by CGM pending settlement by the Company. The commitment under the forward purchase agreement was settled in full during the quarter ended June 30, 2014. The Company recognized these assets and related obligations as of the dates of the forward purchase agreements and recognized all subsequent income and changes in value relating to such assets. As a result of recognizing these assets, the Company’s consolidated statements of income and cash flows for the periods presented include the following amounts related to the forward purchase agreements: Quarter ended Six months ended (in thousands) Statements of income: Interest income $ 1,430 $ 3,584 Interest expense $ 783 $ 2,364 Net gain on investments $ 1,743 $ 803 Net loan servicing fees $ 201 $ 517 Results of REO $ (72 ) $ (473 ) Statements of cash flows: Repayments of mortgage loans $ 1,084 $ 6,413 Sales of REO $ 3,743 $ 5,365 Repayments of borrowings under forward purchase agreements $ (214,742 ) $ (227,866 ) The Company has no other variable interests in the trust entity or other exposure to the creditors of the trust entity that could expose the Company to loss.

Under the terms of the amendment, the maximum loan amount increased from $257 million to $407 million. The $150 million increase was implemented for the purpose of facilitating the financing of excess servicing spread (“ESS”) by the Company. The aggregate loan amount outstanding under the lending facility and relating to advances outstanding with the Company is guaranteed in full by PMT. In connection with the amendment to the lending facility, the Company and PFSI entered into an underlying loan and security agreement, dated as of April 30, 2015, pursuant to which the Company may borrow up to $150 million from PFSI for the purpose of financing ESS. The principal amount of the borrowings under the Loan and Security Agreement is based upon a percentage of the market value of the ESS pledged by the Company, subject to the maximum loan amount described above. Pursuant to the underlying loan and security agreement, the Company granted to PFSI a security interest in all of its right, title and interest in, to and under the ESS pledged to secure loans. The Company and PFSI have agreed that the Company is required to repay PFSI the principal amount of such borrowings plus accrued interest to the date of such repayment, and PFSI is required to repay their lender the corresponding amount under the lending facility. The Company is also required to pay PFSI a fee for the structuring of the lending facility in an amount equal to the portion of the corresponding fee paid by PFSI to their lender under the lending facility and allocable to the increase in the maximum loan amount resulting from the ESS financing. The note matures on October 30, 2015 and interest accrues at a rate based on the lender’s cost of funds. In connection with the initial public offering of PMT’s common shares (“IPO”) on August 4, 2009, the Company entered into an agreement with PCM pursuant to which the Company agreed to reimburse PCM for the $2.9 million payment that it made to the IPO underwriters if the Company satisfied certain performance measures over a specified period (the “Conditional Reimbursement”). Effective February 1, 2013, the Company amended the terms of the reimbursement agreement to provide for the reimbursement of PCM of the Conditional Reimbursement if the Company is required to pay PCM performance incentive fees under the management agreement at a rate of $10 in reimbursement for every $100 of performance incentive fees earned. The reimbursement of the Conditional 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. During the quarter and six months ended June 30, 2015, the Company paid $230,000 and $387,000 to PCM, respectively, compared to $36,000 for the quarter and six months ended June 30, 2014. The Company has also agreed to pay the IPO underwriters an amount to which it agreed at the time of the offering if the Company satisfies certain performance measures over a specified period. As PCM earns performance incentive fees under the management agreement, such 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. During the quarter and six months ended June 30, 2015, the Company paid $459,000 and 772,000 to the underwriters, respectively, compared to $315,000 and $387,000 for the same periods in 2014. In the event the termination fee is payable to PCM under the management agreement and PCM and the underwriters have not received the full amount of the reimbursements and payments under the reimbursement agreement, such amount will be paid in full. The term of the reimbursement agreement expires on February 1, 2019. Other Transactions Following is a summary of the base management and performance incentive fees payable to PCM recorded by the Company: Quarter ended June 30, Six months ended June 30, 2015 2014 2015 2014 (in thousands) Base $ 5,709 $ 5,838 $ 11,439 $ 11,359 Performance incentive 70 3,074 1,343 5,627 Total management fee incurred during the period $ 5,779 $ 8,912 $ 12,782 $ 16,986 In the event of termination of the management agreement between the Company and PCM, PCM 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. The Company reimburses PCM and its affiliates for other expenses, including common overhead expenses incurred on its behalf by PCM and its affiliates, in accordance with the terms of its management agreement as summarized below: Quarter ended June 30, Six months ended June 30, 2015 2014 2015 2014 (in thousands) Reimbursement of: Common overhead incurred by PCM and its affiliates (1) $ 2,702 $ 2,691 $ 5,431 $ 5,269 Expenses incurred on the Company’s behalf 83 104 462 549 $ 2,785 $ 2,795 $ 5,893 $ 5,818 Payments and settlements during the period (2) $ 24,114 $ 14,894 $ 46,866 $ 33,280 (1) For the quarter ended June 30, 2015, in accordance with the terms of the management agreement, PCM provided the Company a discretionary waiver of $700,000 of overhead expenses that otherwise would have been allocable to the Company.

At June 30, 2015, the balance represents payments receivable relating to cash flows from the Company’s investment in ESS and amounts receivable relating to unsettled ESS recaptures. PFSI held 75,000 of the Company’s common shares at both June 30, 2015 and December 31, 2014.

Earnings Per Share

Earnings Per Share [Abstract]
Earnings Per Share	Note 4—Earnings Per Share Basic earnings per share is determined using the two-class method, under which 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. 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. 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 potentially 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 June 30, Six months ended June 30, 2015 2014 2015 2014 (in thousands except per share amounts) Basic earnings per share: Net income $ 28,071 $ 75,211 $ 35,579 $ 113,084 Effect of participating securities—share-based compensation awards (438 ) (433 ) (1,015 ) (841 ) Net income attributable to common shareholders $ 27,633 $ 74,778 $ 34,564 $ 112,243 Weighted-average shares outstanding 74,683 74,065 74,618 72,803 Basic earnings per share $ 0.37 $ 1.01 $ 0.46 $ 1.54 Diluted earnings per share: Net income $ 27,633 $ 75,211 $ 34,564 $ 113,084 Interest on Exchangeable Notes, net of income taxes 2,121 2,079 — 4,156 Net income attributable to diluted shareholders $ 29,754 $ 77,290 $ 34,564 $ 117,240 Weighted-average shares outstanding 74,683 74,065 74,618 72,803 Potentially dilutive securities: Shares issuable pursuant to exchange of the Exchangeable Notes 8,467 8,393 — 8,393 Shares issuable under share-based compensation plan 330 292 379 338 Diluted weighted-average number of shares outstanding 83,480 82,750 74,997 81,535 Diluted earnings per share $ 0.36 $ 0.93 $ 0.46 $ 1.44 Dividends and undistributed earnings allocated to participating securities under the basic and diluted earnings per share calculations require specific shares to be included or excluded that may differ in certain circumstances. For the six months ended June 30, 2015, approximately 8,467,000 shares issuable pursuant to the exchange feature embedded in the Exchangeable Notes were excluded from the diluted earnings per share calculation as inclusion of the exchange of such shares would have been antidilutive.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Loan Sales and Variable Interest Entities	Note 5—Loan Sales and Variable Interest Entities The Company is a variable interest holder in various special purpose entities that relate to its loan transfer and financing activities. These entities are classified as variable interest entities (“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. Unconsolidated VIEs with Continuing Involvement The following table summarizes cash flows between the Company and transferees in transfers that are accounted for as sales where PMT maintains continuing involvement with the mortgage loans, as well as unpaid principal balance information at period end: Quarter ended June 30, Six months ended June 30, 2015 2014 2015 2014 (in thousands) Cash flows: Proceeds from sales $ 3,063,397 $ 2,763,138 $ 5,707,641 $ 4,789,444 Servicing fees received (1) $ 22,738 $ 19,019 $ 44,641 $ 34,907 Period end information: Unpaid principal balance of mortgage loans outstanding $ 36,448,945 $ 29,268,039 Unpaid principal balance of delinquent mortgage loans: 30-89 days delinquent $ 129,316 $ 90,091 90 or more days delinquent Not in foreclosure 28,805 13,325 In foreclosure or bankruptcy 20,063 11,306 48,868 24,631 $ 178,184 $ 114,722 (1) Net of guarantee fees. Consolidated VIE On September 30, 2013, the Company completed a securitization transaction in which a wholly-owned VIE issued $537.0 million in certificates backed by fixed-rate prime jumbo mortgage loans of PMT Loan Trust 2013-J1, at a 3.9% weighted yield. The Company retained $366.8 million of those certificates. The Manager concluded that the Company is the primary beneficiary of the VIE and, as a result, the Company consolidates the VIE. Consolidation of the VIE results in the securitized mortgage loans remaining on the consolidated balance sheets of the Company and the certificates issued by the VIE to nonaffiliates being accounted for as a secured financing. The certificates are secured solely by the assets of the VIE and not by any other assets of the Company. The assets of the VIE are the only source of repayment of the certificates.

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, ESS and MSRs. All derivative financial instruments are recorded on the balance sheet at fair value. The Company has elected to net derivative asset and liability positions, and cash collateral obtained (or posted) by (or 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. As of June 30, 2015 and December 31, 2014, the Company did not enter into reverse repurchase agreements or securities lending transactions that are required to be disclosed in the following tables. Offsetting of Derivative Assets Following is a summary of net derivative assets. As discussed above, all derivatives with the exception of IRLCs are subject to master netting arrangements.

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. Fair Value Accounting Elections The Manager identified all of the Company’s non-cash financial assets and MSRs relating to 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 financial statement items 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 secured financing of the VIE 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 collateralizing this financing. The Company’s subsequent 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 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. For assets sold under agreements to repurchase, borrowings under forward purchase agreements and the Exchangeable Notes, 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.

The initial carrying value of the REO is measured by 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 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 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 assets’ 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% and 4.5% and a single pool for mortgage loans with interest rates below 3%. 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 reduced by the existing valuation allowance for that pool, 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 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 The Company’s cash balances as well as certain of its borrowings are carried at amortized cost. Cash is measured using “Level 1” inputs. The Company’s assets sold under agreements to repurchase and mortgage loans participation and sale agreement are classified as “Level 3” financial statement instruments as of June 30, 2015 due to the lack of current market activity and the Company’s reliance on unobservable inputs to estimate these instruments’ fair values. The Manager has concluded that the fair values of Cash Assets sold under agreements to repurchase, Mortgage loan participation and sale agreement Credit Risk Transfer financing at fair value The Exchangeable Notes are carried at amortized cost. The fair value of the Exchangeable Notes at June 30, 2015 and December 31, 2014 was $233.0 million and $239.0 million, respectively. The fair value of the Exchangeable Notes is estimated using a broker indication of value. The Company has classified the Exchangeable Notes as “Level 3” financial statement items as of June 30, 2015 due to the lack of current market activity and use of a broker’s indication of value to estimate the instrument’s fair value. Valuation Techniques and Inputs Most of the Company’s assets and asset-backed financing agreements are carried at fair value with changes in fair value recognized in current period income. A substantial portion of these items are “Level 3” financial statement items which require the use of unobservable inputs that are significant to the estimation of the items’ fair values. Unobservable inputs reflect the Company’s own assumptions 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” financial statement items, the Manager has assigned the responsibility for estimating fair value of these items 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” financial statement items other than IRLCs and maintaining its valuation policies and procedures. With respect to the Level 3 valuations, the FAV group reports to the Manager’s senior management valuation committee, which oversees and approves the valuations. The FAV group monitors the models used for valuation of the Company’s “Level 3” financial statement items, including the models’ performance versus actual results, and reports those results to the Manager’s senior management valuation committee. The Manager’s senior management valuation committee includes PFSI’s chief executive, financial, operating, credit and asset/liability management officers. The FAV group is responsible for reporting to the Manager’s senior management valuation committee on a monthly basis on the changes in the valuation of the portfolio, 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. With respect to IRLCs, the Manager has assigned responsibility for developing fair values to its capital markets risk management staff. The fair values developed by the capital markets risk management staff are submitted to the Manager’s senior management secondary marketing working group. The Manager’s secondary marketing working group includes PFSI’s chief executive, operating, institutional mortgage banking, capital markets, asset/liability, portfolio risk, and capital markets operations officers. The following is a description of the techniques and inputs used in estimating the fair values of “Level 2” and “Level 3” financial statement items: Mortgage-Backed Securities The Company’s MBS include Agency and senior non-agency MBS. The Company categorized its MBS as “Level 2” financial statement items. Fair value of Agency and senior non-Agency MBS is estimated based on quoted market prices for the Company’s MBS or similar securities. 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” financial statement items. The fair values of mortgage loans acquired for sale at fair value are estimated using their quoted market or contracted price or market price equivalent. For the mortgage loans at fair value held in a VIE, the 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 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. • Loans that are not saleable into active markets, comprised of the Company’s mortgage loans at fair value held outside the VIE and mortgage loans under forward purchase agreements at fair value, are categorized as “Level 3” financial statement items 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 or contracted selling price, discount rates and forecasts of future interest rates, home prices, prepayment speeds, default speeds and loss severities. 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 input variables such as interest rates, home prices, and delinquency status to assess the reasonableness of changes in the loan valuation. The results of the estimates of fair value of “Level 3” mortgage loans are reported to the Manager’s valuation committee as part of its review and approval of monthly valuation results. 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 loan’s delinquency status and 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 loans’ fair value measurement. Increases in home price projections are generally accompanied by an increase in voluntary prepayment speeds. Following is a quantitative summary of key inputs used in the valuation of mortgage loans at fair value: Key inputs June 30, 2015 December 31, 2014 Discount rate Range 2.3% – 15.0% 2.3% – 15.0% Weighted average 7.2% 7.7% Twelve-month projected housing price index change Range 1.9% – 5.2% 4.0% – 5.3% Weighted average 3.9% 4.8% Prepayment speed (1) Range 0.1% – 5.1% 0.0% – 6.5% Weighted average 3.6% 3.1% Total prepayment speed (2) Range 3.6% – 29.6% 0.0% – 27.9% Weighted average 20.9% 21.6% (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 PennyMac Financial Services, Inc. The Company categorizes ESS as a “Level 3” financial statement item. 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 life of the mortgage loans underlying the ESS, thereby reducing the fair value of ESS. Reductions in the fair value of ESS affect income primarily through change in fair value. Interest income for ESS is accrued using the interest method, based upon the expected interest yield from the ESS through the expected life of the underlying mortgages. Changes to expected interest yield result in a change in Interest income Net gain (loss) on investments Following are the key inputs used in determining the fair value of ESS: Range (Weighted average) Key inputs June 30, 2015 December 31, 2014 Unpaid principal balance of underlying mortgage loans (in thousands) $46,809,508 $28,227,340 Average servicing fee rate (in basis points) 32 31 Average ESS rate (in basis points) 16 16 Pricing spread (1) Range 1.7% – 12.4% 1.7% – 12.0% Weighted average 5.0% 5.3% Life (in years) Range 0.3 – 7.3 0.4 – 7.3 Weighted average 6.2 5.8 Annual total prepayment speed (2) Range 7.6% – 74.3% 7.6% – 74.6% Weighted average 9.7% 11.2% (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 The Company categorizes IRLCs as a “Level 3” financial statement item. 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 loans and the probability that the mortgage loan will be purchased as a percentage of the commitments it has made (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 and 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 loans that have decreased in fair value. Following is a quantitative summary of key unobservable inputs used in the valuation of IRLCs: Key inputs June 30, 2015 December 31, 2014 Pull-through rate Range 63.6% – 99.9% 65.0% – 98.0% Weighted average 93.7% 94.9% MSR value expressed as: Servicing fee multiple Range 1.4 – 5.2 0.7 – 5.2 Weighted average 4.4 4.3 Percentage of unpaid principal balance Range 0.3% – 3.7% 0.2% – 1.3% Weighted average 1.1% 1.1% The Company estimates the fair value of commitments to sell loans based on quoted MBS prices. The Company estimates the fair value of the interest rate options and futures it purchases and sells based on observed interest rate volatilities in the MBS market. These derivative financial instruments are categorized by the Company as “Level 2” financial statement items. 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” financial statement item. 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 th

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Note 9—Derivative Financial Instruments The Company engages in interest rate risk management activities in an effort to reduce the variability of earnings caused by changes in interest rates. 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, IRLCs and inventory of mortgage loans acquired for sale. 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 its mortgage loans acquired for sale as well as to the IRLCs it issues to correspondent lenders. The Company bears price risk from the time an IRLC is issued to a correspondent lender to the time the purchased mortgage loan is sold. The Company is exposed to loss if mortgage interest rates increase, because the value of the purchase commitment or mortgage loan acquired for sale decreases. The Company is also exposed to risk relative to the fair value of its MSRs. The Company is exposed to loss in fair value of its MSRs when interest rates decrease. The Company includes MSRs in its hedging activities. The Company enters into Eurodollar futures contracts, which settle daily, to economically hedge net fair value changes of MBS at fair value and the related variable rate repurchase agreement liabilities indexed to LIBOR and a portion of fixed-rate mortgage loans at fair value held by its consolidated VIE. The Company uses the Eurodollar futures with the intention of moderating the risk of changing market interest rates that will result in unfavorable changes in the value of the Company’s fixed-rate assets and economic performance of its LIBOR-indexed variable interest rate repurchase agreement liabilities. The Company does not use derivative financial instruments for purposes other than in support of its risk management activities other than IRLCs, which are generated in the normal course of business when the Company commits to purchase mortgage loans acquired for sale.

Mortgage Loan Participation and Sale Agreement	Note 15—Mortgage Loan Participation and Sale Agreement One of the borrowing facilities secured by mortgage loans acquired for sale is in the form of a mortgage loan participation and sale agreement. 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 the lender pending the securitization of such mortgage loans and the sale of the resulting security. A commitment between the Company and a non-affiliate 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 that 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.

The increase in the Company’s tax benefit is due primarily to an increased loss incurred at the Company’s taxable REIT subsidiary for the quarter and six months ended June 30, 2015 as compared to the same periods in 2014. 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.

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 32—Segments and Related Information The Company has two segments: correspondent production and investment activities. • 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 MBS, using the services of PFSI. Most of the loans the Company has acquired in its correspondent production activities have been eligible for sale to government-sponsored entities such as Fannie Mae and Freddie Mac or through government agencies such as Ginnie Mae. • The investment activities segment represents the Company’s investments in mortgage-related assets, which include distressed mortgage loans, REO, MBS, MSRs and ESS. The Company seeks to maximize the fair value of the distressed mortgage loans that it acquires through proprietary loan modification programs, special servicing or other initiatives focused on keeping borrowers in their homes. Where this is not possible, such as in the case of many nonperforming mortgage loans, the Company seeks to effect property resolution in a timely, orderly and economically efficient manner, including through the use of resolution alternatives to foreclosure.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Segment Reporting	The Company operates in two segments correspondent production and investment activities: • 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 (“PCM” or the “Manager”) and PennyMac Loan Services, LLC (“PLS” or the “Servicer”), both indirect 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 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 investment activities segment represents the Company’s investments in mortgage-related assets, which include distressed mortgage loans, real estate acquired in settlement of loans (“REO”), MBS, mortgage servicing rights (“MSRs”) and excess servicing spread (“ESS”). The Company seeks to maximize the fair value of its acquired distressed mortgage loans through proprietary loan modification programs, special servicing or other initiatives focused on keeping borrowers in their homes. Where this is not possible, such as in the case of many nonperforming mortgage loans, the Company seeks to effect property resolution in a timely, orderly and economically efficient manner, including through the use of resolution alternatives to foreclosure.
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 The accompanying unaudited consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, income, and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year ending December 31, 2015. Intercompany accounts and transactions have been eliminated.

Concentration Risk	Because of the Company’s investment focus, PMT is exposed, to a greater extent than traditional mortgage investors, to the risks 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 to the effects of fluctuations in the residential real estate market on the performance of its investments. Factors influencing these risks include, but are not limited to: • changes in the overall economy and 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 the Servicer’s ability to execute optimal resolutions of problem 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 assumptions that properly anticipate, future outcomes; • the level of government support for problem mortgage loan resolution 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. 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 potentially 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. Fair Value Accounting Elections The Manager identified all of the Company’s non-cash financial assets and MSRs relating to 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 financial statement items 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 secured financing of the VIE 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 collateralizing this financing. The Company’s subsequent 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 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.
