Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business and Basis of Presentation	1. Nature of Business and Basis of Presentation Nature of Business Mr. Cooper Group Inc., collectively with its consolidated subsidiaries, (“Mr. Cooper”, the “Company”, “we”, “us” or “our”) provides servicing, origination and transaction-based services related to single family residences throughout the United States with operations under its primary brands: Mr. Cooper® and Xome®. Mr. Cooper is one of the largest home loan servicers in the country focused on delivering a variety of servicing and lending products, services and technologies. Xome provides technology and data enhanced solutions to homebuyers, home sellers, real estate agents and mortgage companies. The Company’s corporate website is located at www.mrcoopergroup.com . Mr. Cooper, which was previously known as WMIH Corp. (“WMIH”), is a corporation duly organized and existing under the laws of the State of Delaware since May 11, 2015. On July 31, 2018, Wand Merger Corporation (“Merger Sub”), a wholly-owned subsidiary of WMIH merged with and into Nationstar Mortgage Holdings Inc. (“Nationstar”), with Nationstar continuing as a wholly-owned subsidiary of WMIH (the “Merger”). Prior to the Merger, WMIH had limited operations other than its reinsurance business that operated in runoff mode. As a result of the Merger, shares of Nationstar common stock were delisted from the New York Stock Exchange. Following the Merger closing, the combined company traded on NASDAQ under the ticker symbol “WMIH” until October 10, 2018, when WMIH changed its name to “Mr. Cooper Group Inc.” and its ticker symbol to “COOP”. Basis of Presentation For the purpose of financial statement presentation, Mr. Cooper was determined to be the accounting acquirer in the Merger, and Nationstar’s assets and liabilities were recorded at estimated fair value as of the acquisition date. Mr. Cooper’s interim consolidated financial statements for periods following the Merger closing are labeled “Successor” and reflect the acquired assets and liabilities from Nationstar. Under Securities and Exchange Commission (“SEC”) rules, when a registrant succeeds to substantially all of the business of another entity and the registrant’s own operations before the succession appear insignificant relative to the operations assumed or acquired, the registrant is required to present financial information for the acquired entity (the “Predecessor”) for all comparable periods being presented before the acquisition. Due to the acquisition, the Predecessor and Successor financial statements have been prepared on different basis of accounting and are therefore not comparable. Pursuant to the Merger, Nationstar is considered the predecessor company. Therefore, the Company is providing additional information in the accompanying unaudited condensed consolidated financial statements regarding Nationstar’s business for periods prior to July 31, 2018. The predecessor company financial information in this report is labeled “Predecessor” in these consolidated interim financial statements. The consolidated interim financial statements of the Company and Predecessor have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the SEC. Accordingly, the financial statements do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Reports on Form 10-K for the year ended December 31, 2018 . Upon the consummation of the Merger, the Company adopted the significant accounting policies that were implemented by Nationstar and applied to the Predecessor’s financial statements, as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. The interim consolidated financial statements are unaudited; however, in the opinion of management, all adjustments, consisting of normal recurring items, considered necessary for a fair presentation of the results of the interim periods have been included. Dollar amounts are reported in millions, except per share data and other key metrics, unless otherwise noted. The Company evaluated subsequent events through the date these interim consolidated financial statements were issued. Basis of Consolidation The basis of consolidation described below was adopted by Nationstar and applied to the Predecessor financial statements for the periods impacted by the adoption. The Successor’s financial statements reflect the adoption of such standards. The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries, other entities in which the Company has a controlling financial interest and those variable interest entities (“VIE”) where the Company’s wholly-owned subsidiaries are the primary beneficiaries. Assets and liabilities of VIEs and their respective results of operations are consolidated from the date that the Company became the primary beneficiary through the date the Company ceases to be the primary beneficiary. The Company applies the equity method of accounting to investments where it is able to exercise significant influence, but not control, over the policies and procedures of the entity and owns less than 50% of the voting interests. Investments in certain companies over which the Company does not exert significant influence are accounted for as cost method investments. Intercompany balances and transactions on consolidated entities have been eliminated. Business combinations are included in the consolidated financial statements from their respective dates of acquisition. Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates due to factors such as adverse changes in the economy, changes in interest rates, secondary market pricing for loans held for sale and derivatives, strength of underwriting and servicing practices, changes in prepayment assumptions, declines in home prices or discrete events adversely affecting specific borrowers, and such differences could be material. Recent Accounting Guidance Adopted Accounting Standards Update No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), No.2018-10, Codification Improvements to Topic 842, Leases (“ASU 2018-10”), and No. 2018-11, Leases (Topic 842): Targeted Improvements (“ASU 2018-11”), primarily impact lessee accounting by requiring the recognition of a right-of-use asset and a corresponding lease liability on the balance sheet for long-term lease agreements. ASU 2016-02 was effective for the Company on January 1, 2019. ASU 2016-02 provides for a modified retrospective transition approach requiring lessees to recognize and measure leases on the balance sheet at the beginning of either the earliest period presented or as of the beginning of the period of adoption with the option to elect certain practical expedients. The Company has elected to apply ASU 2016-02 as of the beginning of the period of adoption (January 1, 2019) and has not restated comparative periods. The Company elected the package of practical expedients, which, among other items, permits the Company not to reassess under the new standard its prior conclusions about lease identification, lease classification and initial direct costs. The Company also elected the short-term lease recognition exemption for all leases that qualify. Under this practical expedient, for those leases that qualify, the Company does not recognize right-of-use (“ROU”) assets or lease liabilities, which includes not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition. The Company also elected the practical expedient to not separate lease and non-lease components for all of our leases. The Company did not elect the use-of-hindsight practical expedient. As a result of implementing ASU 2016-02, the Company recognized an operating lease ROU asset of $114 and an operating lease liability of $124 on January 1, 2019, with no impact on its consolidated statement of operations. There was no cumulative-effect adjustment to the opening balance of accumulated deficit as a result of the adoption of this standard. The ROU asset and operating lease liability are recorded in other assets, and payables and other liabilities, respectively, in the consolidated balance sheets. See Note 7, Leases for additional information. Accounting Standards Update No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40 - Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract " (“ASU 2018-15”) aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). ASU 2018-15 will be effective for the Company on January 1, 2020. Early adoption is permitted, including adoption in any interim period. In the first quarter of 2019, the Company early adopted ASU 2018-15. The standard did not have a material impact to the Company’s consolidated financial statements. Recent Accounting Guidance Not Yet Adopted Accounting Standards Update No. 2016-13, Financial Instruments - Credit Losses (Topic 326) (“ASU 2016-13”), requires expected credit losses for financial instruments held at the reporting date to be measured based on historical experience, current conditions and reasonable and supportable forecasts. The update eliminates the probable initial recognition threshold in current GAAP and instead reflects an entity’s current estimate of all expected credit losses. Previously, when credit losses were measured under GAAP, an entity generally only considered past events and current conditions in measuring the incurred loss. ASU 2016-13 is effective for interim periods beginning after December 15, 2019. The Company is currently evaluating the potential impact of ASU 2016-13 on its consolidated financial statements. Accounting Standards Update No. 2018-13, Fair Value Measurement (Topic 820) - Changes to the Disclosure Requirements for Fair Value Measurement , (“ASU 2018-13”) removes the requirement to disclose the amount of and reasons for transfers between Level 1 and Level 2 fair value measurement methodologies, the policy for timing of transfers between levels and the valuation processes for Level 3 fair value measurements. It also adds a requirement to disclose changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level 3 measurements. For certain unobservable inputs, entities may disclose other quantitative information in lieu of the weighted average if the other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. ASU 2018-13 will be effective for the Company on January 1, 2020. The Company is currently evaluating the potential impact of ASU 2018-13 on its consolidated financial statements.

Acquisitions	2. Acquisitions Acquisition of Pacific Union Financial, LLC On February 1, 2019, the Company completed the acquisition of all the limited liability units of Pacific Union Financial, LLC (“Pacific Union”), a California limited liability company. The purchase price was estimated to be $116 , which is subject to adjustment. Pacific Union was a privately-held company that was engaged in the origination as well as servicing of residential mortgage loans, and operated throughout the United States. The acquisition allows the Company to expand its servicing portfolio and increase its mortgage lending volume and capabilities. The acquisition has been accounted for in accordance with Financial Accounting Standard Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 805 (“ASC 805”), Business Combinations , using the acquisition method of accounting. Under the acquisition method of accounting, the Company allocated the purchase price of the acquisition to identifiable assets acquired and liabilities assumed based on its estimated fair values as of the acquisition date. The determination of fair value estimates requires management to make certain estimates about discount rates, future expected cash flows, market conditions, and other future events that are highly subjective in nature and may require adjustments. The Company’s estimates are subject to change as the Company obtains additional information and finalizes its review of estimates during the measurement period (up to one year from the acquisition date). The primary areas of the preliminary allocation of fair value of consideration transferred that are not yet finalized relate to the fair value of mortgage servicing rights, loans held for sale, advances and other receivables and payables and accrued liabilities as the Company continues to evaluate the underlying inputs and assumptions that are being used in fair value estimates. Based on the preliminary allocation of fair value, goodwill of $29 has been recorded, which represents the excess of the purchase price over the estimated fair value of tangible and intangible assets acquired, net of the liabilities assumed. The goodwill is primarily attributable to the assembled workforce and synergies with the Company’s current operations. The goodwill is assigned to the Origination and Servicing segments based on expected cash flows and is expected to be deductible for tax purposes. Preliminary Estimated Fair Value of Net Assets Acquired: Cash and cash equivalents $ 37 Restricted cash 2 Mortgage servicing rights 271 Advances and other receivables 84 Mortgage loans held for sale 536 Mortgage loans held for investment 1 Property and equipment 10 Other assets 483 Fair value of assets acquired 1,424 Notes payable (1) 294 Advance facilities 13 Warehouse facilities 393 Payables and other liabilities 519 Other nonrecourse debt 129 Fair value of liabilities assumed 1,348 Total fair value of net tangible assets acquired 76 Intangible assets: Customer relationships (2) 11 Preliminary goodwill 29 $ 116 (1) Notes payables was subsequently paid off in February 2019 after the consummation of the acquisition. (2) The estimated fair values for customer relationships were measured using the excess earnings method and were determined to have a remaining useful life of 10 years. The purchase price allocation has not been finalized as of March 31, 2019 , as the Company continues to analyze respective valuations of acquired assets and assumed liabilities as specified above. The Company incurred total acquisition costs of $2 during the three months ended March 31, 2019 , of which $1 are included in salaries, wages and benefits expense and $1 in general and administrative expense in the Company’s consolidated statements of operations. The acquisition costs were primarily related to legal, accounting and consulting services. For the three months ended March 31, 2019 , the operations contributed by this acquisition generated consolidated total revenues of $39 and income before income tax of $14 , which are reported in the Company’s consolidated statements of operations. The following unaudited pro forma financial information presents the combined results of operations for the three months ended March 31, 2019 as if the transaction had occurred on January 1, 2019. Three Months Ended March 31, 2019 Pro forma total revenues $ 269 Pro forma net loss $ (184 ) Acquisition of Nationstar Mortgage Holdings Inc. Upon the Merger with Nationstar on July 31, 2018, each share of Nationstar’s common stock issued and outstanding immediately prior to the Effective Time was converted into the right to receive, at the election of the holder of such share, (i) $18.00 per share in cash, without interest, or (ii) 12.7793 shares (prior to the 1-for-12 reverse stock split) of validly issued, fully paid and nonassessable shares of WMIH common stock (the “Merger Consideration”). The Merger Consideration was subject to automatic proration and adjustment pursuant to the Merger Agreement to ensure that the total amount of cash paid (excluding cash paid in lieu of fractional shares) equaled approximately $1,226 . Pursuant to the Merger Agreement, immediately prior to the Effective Time, subject to certain exceptions, (i) each then-outstanding share of Nationstar restricted stock automatically vested in full and was converted into the right to receive the Merger Consideration, as elected by the holder thereof, and (ii) each then-outstanding Nationstar restricted stock unit, whether vested or unvested, was automatically vested in full, assumed by WMIH and converted into a WMIH restricted stock unit entitling the holder thereof to receive upon settlement the Merger Consideration, as elected by the holder. Upon closing the Merger, all outstanding WMIH Series B Preferred Stock and all outstanding warrants to purchase shares of WMIH common stock were converted into common stock of WMIH. Total purchase price was approximately $1,777 , consisting of cash paid of $1,226 and transferred stock valued at $551 . The purchase price was funded from available cash on hand and borrowings under senior unsecured notes (see discussion below). Prior to the acquisition, Nationstar was a publicly-held company that earned fees through the delivery of servicing, origination and transaction-based services related primarily to single-family residences throughout the United States. This acquisition marks the Company’s initial entry into the mortgage servicing industry that Nationstar operates in and is consistent with the Company’s business strategy. On July 13, 2018, Merger Sub closed the offering of $950 aggregate principal amount of 8.125% Notes due 2023 (the “2023 Notes”) and $750 aggregate principal amount of 9.125% Notes due 2026 (the “2026 Notes” and, together with the 2023 Notes, the “New Notes”). The proceeds from the New Notes were used, together with the proceeds from the issuance of the Company’s common stock and the Company’s cash and restricted cash on hand, to consummate the Company’s acquisition of Nationstar and the refinancing of certain of Nationstar’s existing debt and to pay related fees and expenses. At the consummation of the acquisition, Merger Sub merged with and into Nationstar, with Nationstar continuing as a wholly-owned subsidiary of the Company. After the Merger, Nationstar assumed all of Merger Sub’s obligations under the New Notes. The acquisition has been accounted for in accordance with ASC 805, Business Combinations , using the acquisition method of accounting. Under the acquisition method of accounting, the Company allocated the purchase price of the acquisition to identifiable assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date. The Company recorded preliminary goodwill of $65 , which represents the excess of the purchase price over the estimated fair value of tangible and intangible assets acquired, net of the liabilities assumed. The goodwill is primarily attributable to the assembled workforce and synergies from the future growth and strategic advantages in the mortgage industry. The entire goodwill is assigned to the Servicing segment and will not be deductible for tax purposes. The table below presents the calculation of aggregate purchase price. Purchase Price: Converted WMIH common shares (prior to reverse stock split) in millions 394 Price per share, based on price of $1.398 for WMIH stock on July 31, 2018 $ 1.398 Purchase price from common stock issued 551 Purchase price from cash payment 1,226 Total purchase price $ 1,777 The allocation of the fair value of the acquired business was based on preliminary valuations of the estimated net fair value of the assets acquired. The determination of fair value estimates requires management to make certain estimates about discount rates, future expected cash flows, market conditions, and other future events that are highly subjective in nature and may require adjustments. The Company’s estimates are subject to change as the Company obtains additional information and finalizes its review of estimates during the measurement period (up to one year from the acquisition date). The primary areas of the preliminary allocation of fair value of consideration transferred that are not yet finalized relate to the fair value of advances and other receivables and payables and accrued liabilities. The Company will record any adjustments to the preliminary fair value estimates in the reporting period in which the adjustments are determined. Fair value adjustments based on updated estimates could materially affect the goodwill recorded on the acquisition. The preliminary allocation of the purchase price to the acquired assets and liabilities is as follows: Preliminary Estimated Fair Value of Net Assets Acquired: Cash and cash equivalents $ 166 Restricted cash 430 Mortgage servicing rights 3,422 Advances and other receivables 1,262 Reverse mortgage interests 9,189 Mortgage loans held for sale 1,514 Mortgage loans held for investment 125 Property and equipment 96 Other assets 610 Fair value of assets acquired 16,814 Unsecured senior notes 1,830 Advance facilities 551 Warehouse facilities 2,701 Payables and other liabilities 1,352 MSR related liabilities—nonrecourse 1,065 Mortgage servicing liabilities 123 Other nonrecourse debt 7,583 Fair value of liabilities assumed 15,205 Total fair value of net tangible assets acquired 1,609 Intangible assets (1) 103 Preliminary goodwill 65 $ 1,777 (1) The following intangible assets were acquired in the Nationstar acquisition. Useful Life (Years) Fair Value Customer relationships (i) 6 $ 61 Tradename (ii) 5 8 Technology (ii) 3-5 11 Internally developed software (iii) 2 23 Total $ 103 (i) The estimated fair values for customer relationships were measured using the excess earnings method. (ii) The estimated fair values for tradename and technology were measured using the relief-from-royalty method. This method assumes the tradename and technology have value to the extent the owner is relieved of the obligation to pay royalties for the benefits received from these assets. (iii) The estimated fair values for internally developed software were measured using the replacement cost method. The preliminary allocation of fair value as of December 31, 2018 resulted in goodwill of $10 . As previously disclosed, the fair value related to reverse mortgage assets and liabilities had not been finalized. During the first quarter of 2019, the Company obtained additional information in finalizing its review regarding a market participant view of the cost to service assumption related to the valuation of reverse mortgage assets and liabilities. This additional information was used in finalizing the Company’s review of the fair value of the reverse mortgage assets and liabilities and resulted in a reduction of $24 in reverse mortgage interests, a reduction of $6 in reverse mortgage servicing rights and an increase of $37 in mortgage servicing liabilities. In addition, a reduction of $12 in payables and other liabilities was recorded for the tax impact related to the revised valuation, for a total adjustment to goodwill of $55 . As a result of the revised fair value, the Company recorded $7 to service related, net revenue and $1 to interest income, for a total $8 increase to earnings in the consolidated statement of operations for the three months ended March 31, 2019 . Goodwill totaled $65 as of March 31, 2019 after taking into account these measurement period adjustments. The purchase price allocation has not been finalized as of March 31, 2019 , as the Company continues to analyze the valuations assigned to the acquired assets and assumed liabilities. During the three months ended March 31, 2019 , the Company finalized its valuation of reverse mortgage assets and liabilities related to loan specific cash flows. However, the Company has not yet finalized valuation related to advances and other receivables recorded within reverse mortgage interest primarily as unsecuritized interests in addition to payables and accrued liabilities. WMIH incurred total acquisition costs of $92 prior to the consummation of the Merger, of which $4 was incurred in the three months ended March 31, 2018 . The acquisition costs were primarily related to legal, accounting and consulting services and were expensed as incurred through July 31, 2018. Included in the total acquisition costs was a transaction fee of $25 to KKR Capital Markets LLC (“KCM”), an affiliate of KKR Wand Investors Corporation, which is WMIH’s largest stockholder, for acting as a non-exclusive financial advisor to WMIH with respect to the Merger and an arrangement fee of $7 to KCM for acting as a placement agent with respect to a bridge financing facility in connection with the Merger that was not executed. In addition, WMIH incurred $38 of costs related to borrowings under the Notes, which was capitalized in debt costs. WMIH also paid KCM a deferred fee of $8 , which initially reduced the carrying value of the Series B Preferred Stock. This fee was payable in connection with the conversion of Series B Preferred Stock to WMIH’s common stock upon consummation of the Merger. The Predecessor incurred total acquisition costs of $27 in connection with the Merger. Included in the Predecessor’s consolidated statements of operations for the three months ended March 31, 2018 were $3 of acquisition costs incurred by Nationstar. Included in the Company’s consolidated statements of operations for the three months ended March 31, 2019 were $1 of acquisition costs related to the compensation arrangements incurred by the Company related to the Merger. Acquisition of Assurant Mortgage Solutions (“AMS”) On August 1, 2018, Xome Holdings LLC, a wholly-owned subsidiary of the Company, acquired AMS for $38 in cash with additional consideration dependent on the achievement of certain future performance targets, which was initially estimated at $15 as of December 31, 2018. Total purchase price was estimated at $53 . The acquisition expands Xome’s product footprint and grows its third-party client portfolio across its valuation, title and field services businesses. The Company finalized its purchase price allocation and recorded intangible assets of $24 and goodwill of $13 in 2018. The Company expects entire goodwill to be deductible for tax purposes. Under ASC 805, Business Combinations , the contingent consideration was remeasured to fair value of $4 at March 31, 2019 . The $11 change in the fair value was included in other income (expenses) within the consolidated statement of operations for the three months ended March 31, 2019 .

Mortgage Servicing Rights (MSRs) and Related Liabilities	3. Mortgage Servicing Rights and Related Liabilities The following table sets forth the carrying value of the Company’s mortgage servicing rights (“MSRs”) and the related liabilities. Successor MSRs and Related Liabilities March 31, 2019 December 31, 2018 Forward MSRs - fair value $ 3,481 $ 3,665 Reverse MSRs - amortized cost 7 11 Mortgage servicing rights $ 3,488 $ 3,676 Mortgage servicing liabilities - amortized cost $ 90 $ 71 Excess spread financing - fair value $ 1,309 $ 1,184 Mortgage servicing rights financing - fair value 34 32 MSR related liabilities - nonrecourse at fair value $ 1,343 $ 1,216 Mortgage Servicing Rights The Company owns and records at fair value the rights to service traditional residential mortgage (“forward”) loans for others either as a result of purchase transactions or from the retained servicing associated with the sales and securitizations of loans originated. MSRs are comprised of servicing rights related to both agency and non-agency loans. The following table sets forth the activities of forward MSRs. Successor Predecessor MSRs - Fair Value Three Months Ended March 31, 2019 Three Months Ended March 31, 2018 Fair value - beginning of period $ 3,665 $ 2,937 Additions: Servicing retained from mortgage loans sold 66 68 Purchases of servicing rights (1) 409 19 Dispositions: Sales of servicing assets (260 ) — Changes in fair value: Changes in valuation inputs or assumptions used in the valuation model (332 ) 239 Other changes in fair value (67 ) (69 ) Fair value - end of period $ 3,481 $ 3,194 (1) Purchases of servicing rights during the three months ended March 31, 2019 includes $271 of mortgage servicing rights that were acquired from Pacific Union. See Note 2, Acquisitions for further discussion. From time to time, the Company sells its ownership interest in certain MSRs and is retained as the subservicer for the sold assets. The Company has evaluated the sale accounting requirements related to these transactions, including the Company’s continued involvement as the subservicer, and concluded that these transactions qualify for sale accounting treatment. During the three months ended March 31, 2019 , the Company sold $19,409 in unpaid principal balance (“UPB”) of forward MSRs, of which $19,276 in UPB were retained by the Company as subservicer. MSRs measured at fair value are segregated between credit sensitive and interest sensitive pools at acquisition of MSRs. Credit sensitive pools are primarily impacted by borrower performance under specified repayment terms, which most directly impacts involuntary prepayments and delinquency rates. Interest sensitive pools are primarily impacted by changes in forecasted interest rates, which in turn impact voluntary prepayment speeds. The Company assesses whether acquired portfolios are more credit sensitive or interest sensitive in nature on the date of acquisition. Numerous factors are considered in making this assessment, including loan-to-value ratios, FICO scores, percentage of portfolio previously modified, portfolio seasoning and similar criteria. The determination between credit sensitive and interest sensitive for a pool is made at the date of acquisition, and no subsequent changes are made. Credit sensitive portfolios generally consist of higher delinquency, single-family non-conforming residential forward mortgage loans serviced for agency and non-agency investors. Due to the Company’s focus on recapture and modifications, significant amounts of the credit sensitive portfolio have been re-underwritten and, therefore, behave more like the interest sensitive portfolio. Interest sensitive portfolios generally consist of lower delinquency, single-family conforming residential forward mortgage loans for agency investors. The following table provides a breakdown of credit sensitive and interest sensitive unpaid principal balance (“UPB”) for the Company’s forward MSRs. Successor March 31, 2019 December 31, 2018 MSRs - Sensitivity Pools UPB Fair Value UPB Fair Value Credit sensitive $ 153,565 $ 1,626 $ 135,752 $ 1,495 Interest sensitive 150,127 1,855 159,729 2,170 Total $ 303,692 $ 3,481 $ 295,481 $ 3,665 The Company used the following key weighted-average inputs and assumptions in estimating the fair value of MSRs. Successor March 31, 2019 December 31, 2018 Credit Sensitive Discount rate 11.3 % 11.3 % Total prepayment speeds 13.5 % 11.8 % Expected weighted-average life 6.0 years 6.4 years Interest Sensitive Discount rate 9.4 % 9.3 % Total prepayment speeds 12.5 % 10.0 % Expected weighted-average life 6.1 years 7.0 years The following table shows the hypothetical effect on the fair value of the Successor’s MSRs when applying certain unfavorable variations of key assumptions to these assets for the dates indicated. Successor Discount Rate Total Prepayment Speeds MSRs - Hypothetical Sensitivities 100 bps Adverse Change 200 bps Adverse Change 10% Adverse Change 20% Adverse Change March 31, 2019 Mortgage servicing rights $ (125 ) $ (241 ) $ (147 ) $ (283 ) December 31, 2018 Mortgage servicing rights $ (137 ) $ (265 ) $ (129 ) $ (250 ) These hypothetical sensitivities should be evaluated with care. The effect on fair value of a 10% adverse change in assumptions generally cannot be determined because the relationship of the change in assumptions to the fair value may not be linear. Additionally, the impact of a variation in a particular assumption on the fair value is calculated while holding other assumptions constant. In reality, changes in one factor may lead to changes in other factors, which could impact the above hypothetical effects. Reverse Mortgage Servicing Rights and Liabilities - Amortized Cost The Company services certain HECM reverse mortgage loans with an unpaid principal balance of $27,014 and $28,415 as of March 31, 2019 and December 31, 2018 , respectively. Mortgage servicing liabilities (“MSL”) had an ending balance of $90 and $71 as of March 31, 2019 and December 31, 2018 , respectively. For the three months ended March 31, 2019 and 2018 , the Company and Predecessor accreted $18 and $8 of the MSL and recorded other MSL adjustments of $37 and $3 , respectively. The MSL adjustment recorded by the Company relates to the fair value adjustments for MSL assumed from the Merger as a result of revised cost to service assumption in the valuation of MSL during the measurement period. See Note 2, Acquisitions for further information. Such accretion recorded by the Predecessor relates to previous portfolio acquisitions. Reverse MSR had an ending balance of $7 and $11 as of March 31, 2019 and December 31, 2018 , respectively. For the three months ended March 31, 2019 , the Company amortized $2 and recorded other MSR adjustments of $6 . The MSR adjustment recorded by the Company relates to the fair value adjustments for MSR assumed from the Merger as a result of revised cost to service assumption in the valuation of MSR during the measurement period. See Note 2, Acquisitions for further information. For the three months ended March 31, 2018 , the Predecessor recorded other MSR adjustments of $4 . The fair value of the reverse MSR was $7 and $11 as of March 31, 2019 and December 31, 2018 , respectively. The fair value of the MSL was $75 and $53 as of March 31, 2019 and December 31, 2018 , respectively. Management evaluates reverse MSRs and MSLs each reporting period for impairment. Based on management’s assessment at March 31, 2019 , no impairment or increased obligation was needed. Excess Spread Financing - Fair Value In order to finance the acquisition of certain MSRs on various portfolios, the Company has entered into sale and assignment agreements with a third-party associated with funds and accounts under management of BlackRock Financial Management Inc. (“BlackRock”), a third-party associated with funds and accounts under management of V ä rde Partners, Inc. (“Varde”) and with certain affiliated entities formed and managed by New Residential Investment Corp. (“New Residential”). The Company sold to such entities the right to receive a specified percentage of the excess cash flow generated from the Portfolios after receipt of a fixed base servicing fee per loan. Servicing fees associated with traditional MSRs can be segregated into a contractually specified base servicing fee component and an excess servicing fee. The base servicing fee, along with ancillary income and earnings on escrows, is designed to cover costs incurred to service the specified pool plus a reasonable profit margin. The remaining servicing fee is considered excess. The Company retains all the base servicing fee, along with ancillary revenues and earnings on escrows, associated with servicing the Portfolios and retains a portion of the excess servicing fee. The Company continues to be the servicer of the Portfolios and provides all servicing and advancing functions. Contemporaneous with the above, the Company entered into refinanced loan obligations with New Residential, BlackRock and Varde. Should the Company refinance any loan in the Portfolios, subject to certain limitations, it will be required to transfer the new loan or a replacement loan of similar economic characteristics into the Portfolios. The new or replacement loan will be governed by the same terms set forth in the sale and assignment agreement described above, which is the primary driver of the recapture rate assumption. The range of key assumptions used in the Company’s valuation of excess spread financing are as follows. Successor Excess Spread Financing Prepayment Speeds Average Discount Rate Recapture Rate March 31, 2019 Low 6.8% 4.7 8.5% 7.9% High 18.3% 7.2 13.9% 33.1% Weighted-average 12.9% 5.9 10.4% 20.4% December 31, 2018 Low 6.0% 5.0 8.5% 8.5% High 16.7% 8.1 13.9% 30.5% Weighted-average 11.0% 6.5 10.4% 18.6% The following table shows the hypothetical effect on Company’s excess spread financing fair value when applying certain unfavorable variations of key assumptions to these liabilities for the dates indicated. Successor Discount Rate Prepayment Speeds Excess Spread Financing - Hypothetical Sensitivities 100 bps Adverse Change 200 bps Adverse Change 10% Adverse Change 20% Adverse Change March 31, 2019 Excess spread financing $ 50 $ 104 $ 50 $ 106 December 31, 2018 Excess spread financing $ 47 $ 99 $ 38 $ 81 As the cash flow assumptions utilized in determining the fair value amounts in the excess spread financing are based on the related cash flow assumptions utilized in the financed MSRs, any fair value changes recognized in the financed MSRs attributable to a related cash flow assumption would inherently have an inverse impact on the carrying amount of the related excess spread financing. For example, while an increase in discount rates would negatively impact the value of the Company’s financed MSRs, it would reduce the carrying value of the associated excess spread financing liability. These hypothetical sensitivities should be evaluated with care. The effect on fair value of a 10% variation in assumptions generally cannot be determined because the relationship of the change in assumptions to the fair value may not be linear. Additionally, the impact of a variation in a particular assumption on the fair value is calculated while holding other assumptions constant. In reality, changes in one factor may lead to changes in other factors, which could impact the above hypothetical effects. Also, a positive change in the above assumptions would not necessarily correlate with the corresponding decrease in the net carrying amount of the excess spread financing. Mortgage Servicing Rights Financing - Fair Value From December 2013 through June 2014, the Company entered into agreements to sell a contractually specified base servicing fee component of certain MSRs and servicing advances under specified terms to a joint venture capitalized by New Residential and certain unaffiliated third-party investors. The Company continues to be the named servicer, and, for accounting purposes, ownership of the mortgage servicing rights continues to reside with the Company. Accordingly, the Company records the MSRs and an MSR financing liability associated with this transaction in its consolidated balance sheets. The following table sets forth the weighted average assumptions used in the valuation of the mortgage servicing rights financing liability. Successor Mortgage Servicing Rights Financing Assumptions March 31, 2019 December 31, 2018 Advance financing rates 3.9 % 4.2 % Annual advance recovery rates 19.3 % 19.0 % The following table sets forth the items comprising revenues associated with servicing loan portfolios. Successor Predecessor Servicing Revenue Three Months Ended March 31, 2019 Three Months Ended March 31, 2018 Contractually specified servicing fees (1) $ 281 $ 250 Other service-related income (1)(2) 50 28 Incentive and modification income (1) 7 15 Late fees (1) 25 24 Reverse servicing fees 9 19 Mark-to-market adjustments (3) (293 ) 152 Counterparty revenue share (4) (48 ) (45 ) Amortization, net of accretion (5) (23 ) (48 ) Total servicing revenue $ 8 $ 395 (1) Amounts include subservicing related revenues. (2) Amount for the three months ended March 31, 2019 included a gain of $21 from the execution of a clean-up call option on a reverse mortgage loan trust, as the Company was the master servicer and holder of clean-up call rights. (3) Mark-to-market (“MTM”) adjustments include fair value adjustments on MSR, excess spread financing and MSR financing liabilities. The amount of MSR MTM includes the impact of negative modeled cash flows which have been transferred to reserves on advances and other receivables. The negative modeled cash flows relate to advances and other receivables associated with inactive and liquidated loans that are no longer part of the MSR portfolio. The impact of negative modeled cash flows was $11 for the three months ended March 31, 2019 . The impact of negative modeled cash flows for the Predecessor was $12 for three months ended March 31, 2018 . (4) Counterparty revenue share represents the excess servicing fee that the Company pays to the counterparties under the excess spread financing arrangements and the payments made associated with MSRs financing arrangements. (5) Amortization is net of excess spread accretion of $36 and MSL accretion of $18 for the three months ended March 31, 2019 . Amortization for the Predecessor is net of excess spread accretion of $30 for the three months ended March 31, 2018 . The Predecessor recorded MSL accretion within reverse servicing fees, whereas the Successor has elected to record MSL accretion within Amortization, net of accretion.

Advances are primarily recovered through reimbursement from the investor, proceeds from sale of loan collateral or mortgage insurance claims. Reserves for advances and other receivables on loans transferred out of the MSR portfolio are established within advances and other receivables. The Company estimates and records an asset for estimated recoveries to be collected from prior servicers for their respective portion of the losses associated with the underlying loans that were not serviced in accordance with established guidelines. Receivables from prior servicers totaled $94 and $94 for Company’s forward loan portfolio at March 31, 2019 and December 31, 2018 , respectively. The following table sets forth the activities of the reserves for advances and other receivables.

Other additions represent reclassifications of required reserves provisioned within other balance sheet accounts as associated serviced loans become inactive or liquidate. Purchase Discount for Advances and Other Receivables In connection with the acquisition of Pacific Union in February 2019, the Company recorded the acquired advances and other receivables at estimated fair value as of the acquisition date, which resulted in a preliminary purchase discount of $19 . Refer to Note 2, Acquisitions for discussion of the Pacific Union acquisition. In 2018, the Company recorded the acquired advances and other receivables in connection with the Merger at estimated fair value as of the acquisition date, which resulted in a preliminary purchase discount of $302 . As of March 31, 2019 , a total of $104 purchase discount has been utilized with $217 purchase discount remaining.

Reverse Mortgage Interests [Abstract]
Reverse Mortgage Interests, Net	5. Reverse Mortgage Interests, Net Reverse mortgage interests, net consists of the following: Successor Reverse Mortgage Interests, Net March 31, 2019 December 31, 2018 Participating interests in HECM mortgage-backed securities (“HMBS”), net of $36 and $58 premium, respectively $ 5,293 $ 5,664 Other interests securitized, net of $112 and $100 discount, respectively 950 1,064 Unsecuritized interests, net of $95 and $122 discount, respectively 1,254 1,219 Reserves (8 ) (13 ) Total reverse mortgage interests, net $ 7,489 $ 7,934 Participating Interests in HMBS Participating interests in HMBS consist of the Company’s reverse mortgage interests in HECM loans which have been transferred to GNMA and subsequently securitized through the issuance of HMBS. During the three months ended March 31, 2019 and 2018, a total of $82 and $85 in UPB was transferred to GNMA and securitized by the Company and Predecessor, respectively. In March 2019, the Company entered into an agreement with Fannie Mae for the transfer of reverse mortgage loans. As a result, $61 was transferred from Fannie Mae and securitized into GNMA HMBS during the three months ended March 31, 2019 . Other Interests Securitized Other interests securitized consist of reverse mortgage interests that no longer meet HMBS program eligibility criteria and have been repurchased out of HMBS. These reverse mortgage interests have subsequently been transferred to private securitization trusts and are accounted for as a secured borrowing. No such securitizations occurred during the three months ended March 31, 2019 . The Company sold $20 UPB of Trust 2018-3 during the three months ended March 31, 2019 . During the three months ended March 31, 2018 , the Predecessor securitized a total of $443 UPB through Trust 2018-1 and Trust 2018-2 and a total of $284 UPB from Trust 2016-2 and Trust 2016-3 were called and the related debt was extinguished. Refer to Other Nonrecourse Debt in Note 10, Indebtedness , for additional information. Unsecuritized Interests Unsecuritized interests in reverse mortgages consists of the following: Successor March 31, 2019 December 31, 2018 Repurchased HECM loans (exceeds 98% MCA) $ 941 $ 949 HECM related receivables 270 300 Funded borrower draws not yet securitized 114 76 REO-related receivables 24 16 Purchase discount (95 ) (122 ) Total unsecuritized interests $ 1,254 $ 1,219 Unsecuritized interests include repurchased HECM loans for which the Company is required to repurchase from the HMBS pool when the outstanding principal balance of the HECM loan is equal to or greater than 98% of the maximum claim amount (“MCA”) established at origination in accordance with HMBS program guidelines. The Company and the Predecessor repurchased a total of $740 and $1,051 of HECM loans out of GNMA HMBS securitizations during the three months ended March 31, 2019 and 2018, respectively, of which $188 and $229 were subsequently assigned to a third party in accordance with applicable servicing agreements, respectively. To the extent a loan is not subject to applicable servicing agreements and assigned to a third party, the loan is either subject to assignment to U.S. Department of Housing and Urban Development (“HUD”), per contractual obligations with GNMA, liquidated via a payoff from the borrower or liquidated via a foreclosure according to the terms of the underlying mortgage. The Company and the Predecessor also estimate and record an asset for probable recoveries from prior servicers for their respective portion of the losses associated with the underlying loans that were not serviced in accordance with established guidelines. Receivables from prior servicers totaled $16 and $18 for the Company’s reverse loan portfolio at March 31, 2019 and December 31, 2018 , respectively. Reserves for Reverse Mortgage Interests The Company records reserves related to reverse mortgage interests based on potential unrecoverable costs and loss exposures expected to be realized. Recoverability is determined based on the Company’s ability to meet HUD servicing guidelines and is viewed as two different categories of expenses: financial and operational. Financial exposures are defined as the cost of doing business related to servicing the HECM product and include potential unrecoverable costs primarily based on HUD claim guidelines related to recoverable expenses and unfavorable changes in the appraised value of the loan collateral. Operational exposures are defined as unrecoverable debenture interest curtailments imposed for missed HUD-specified servicing timelines. Reserves for reverse mortgage interests are related to both financial and operational exposures. The activity of the reserves for reverse mortgage interests is set forth below.

Mortgage Loans Held for Sale and Investment [Abstract]
Mortgage Loans Held for Sale and Investment	6. Mortgage Loans Held for Sale and Investment Mortgage Loans Held for Sale The Company maintains a strategy of originating and purchasing residential mortgage loan products primarily for the purpose of selling to GSEs or other third-party investors in the secondary market on a servicing-retained basis. The Company focuses on assisting customers currently in the Company’s servicing portfolio with refinancing of loans or new home purchases. Generally, all newly originated mortgage loans held for sale are securitized and transferred to GSEs or delivered to third-party purchasers shortly after origination on a servicing-retained basis. Mortgage loans held for sale are recorded at fair value as set forth below. Successor March 31, 2019 December 31, 2018 Mortgage loans held for sale – UPB $ 2,077 $ 1,568 Mark-to-market adjustment (1) 93 63 Total mortgage loans held for sale $ 2,170 $ 1,631 (1) The mark-to-market adjustment is recorded in net gain on mortgage loans held for sale in the consolidated statements of operations. The Company accrues interest income as earned and places loans on non-accrual status after any portion of principal or interest has been delinquent for more than 90 days. Accrued interest is recorded as interest income in the consolidated statements of operations. The total UPB of mortgage loans held for sale on non-accrual status was as follows: Successor March 31, 2019 December 31, 2018 Mortgage Loans Held for Sale - UPB UPB Fair Value UPB Fair Value Non-accrual (1) $ 26 $ 23 $ 45 $ 42 (1) Non-accrual includes $22 and $40 of UPB related to Ginnie Mae repurchased loans as of March 31, 2019 and December 31, 2018, respectively. From time to time, the Company exercises its right to repurchase individual delinquent loans in Ginnie Mae securitization pools to minimize interest spread losses, to re-pool into new Ginnie Mae securitizations or to otherwise sell to third-party investors. During the three months ended March 31, 2019 , the Company repurchased $67 of delinquent Ginnie Mae loans and securitized or sold to third-party investors $39 of previously repurchased loans. During the three months ended March 31, 2018 , the Predecessor repurchased $68 of delinquent Ginnie Mae loans and securitized or sold to third-party investors $88 of previously repurchased loans. As of March 31, 2019 and 2018 , $43 and $39 of the repurchased loans have re-performed and were held in accrual status, respectively, and remaining balances continue to be held under a nonaccrual status. The total UPB of mortgage loans held for sale for which the Company has begun formal foreclosure proceedings was $20 and $33 as of March 31, 2019 and December 31, 2018 , respectively. The following table details a roll forward of the change in the account balance of mortgage loans held for sale. Successor Predecessor Mortgage loans held for sale Three Months Ended March 31, 2019 Three Months Ended March 31, 2018 Balance - beginning of period $ 1,631 $ 1,891 Mortgage loans originated and purchased, net of fees (1) 6,252 5,088 Loans sold (6,088 ) (5,649 ) Repurchase of loans out of Ginnie Mae securitizations 364 251 Transfer of mortgage loans held for sale to advances/accounts receivable, net related to claims (2) (3 ) (3 ) Net transfer of mortgage loans held for sale from REO in other assets (3) 3 8 Changes in fair value 10 (5 ) Other purchase-related activities (4) 1 8 Balance - end of period $ 2,170 $ 1,589 (1) Mortgage loans originated and purchased during the three months ended March 31, 2019 includes $536 of loans held for sale that were acquired from Pacific Union. See Note 2, Acquisitions for further discussion. (2) Amounts are comprised of claims made on certain government insured mortgage loans upon completion of the REO sale. (3) Net amounts are comprised of REO in the sales process, which are transferred to other assets, and certain government insured mortgage REO, which are transferred from other assets upon completion of the sale so that the claims process can begin. (4) Amounts are comprised primarily of non-Ginnie Mae loan purchases and buyouts. For the three months ended March 31, 2019 and 2018 , the Company received proceeds of $6,194 and $5,709 , respectively, on the sale of mortgage loans held for sale, resulting in gains of $106 and $60 , respectively. The Company has the right to repurchase any individual loan in a Ginnie Mae securitization pool if that loan meets certain criteria, including being delinquent greater than 90 days. The majority of Ginnie Mae repurchased loans are repurchased solely with the intent to re-pool into new Ginnie Mae securitizations upon re-performance of the loan or to otherwise sell to third-party investors. Therefore, these loans are classified as held for sale. The amounts repurchased out of Ginnie Mae pools, as presented above, are primarily in connection with loan modifications and loan resolution activity as part of the Company’s contractual obligations as the servicer of the loans.

Leases [Abstract]
Leases, Finance	7. Leases Operating leases in which the Company is the lessee are recorded as operating lease ROU assets and operating lease liabilities, included in other assets and payables and other liabilities, respectively, on its consolidated balance sheets as of March 31, 2019 . The Company does not currently have any significant finance leases in which it is the lessee. Operating lease ROU assets represent the Company’s right to use an underlying asset during the lease term and operating lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and operating lease liabilities are recognized at lease commencement based on the present value of the remaining lease payments using a discount rate that represents the Company’s incremental borrowing rate at the lease commencement date. ROU assets are further adjusted for lease incentives. Operating lease expense, which is comprised of amortization of the ROU asset and the implicit interest accreted on the operating lease liability, is recognized on a straight-line basis over the lease term, and is recorded in general and administrative expenses in the consolidated statements of operations. The Company’s leases relate primarily to office space and equipment, with remaining lease terms of generally 1 to 9 years . Certain lease arrangements contain extension options, which typically range from 3 to 5 years , at the then fair market rental rates. As these extension options are not generally considered reasonably certain of exercise, they are not included in the lease term. As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the lease commencement date in determining the present value of the lease payments. As of March 31, 2019 , operating lease ROU assets and liabilities were $133 and $142 , respectively. The table below summarizes the Company’s net lease cost: Successor Three Months Ended March 31, 2019 Operating lease cost $ 8 Short-term lease cost 1 Sublease income (1) — Net lease cost $ 9 (1) Amount is less than $1 .

Proceeds are received in exchange for securitized advances on the HECM loan amounts transferred to GNMA, and the Company retains a beneficial interest (referred to as a “participating interest”) in the securitization trust in which the HECM loans and HMBS obligations are held and assume both issuer and servicer responsibilities in accordance with GNMA HMBS program guidelines. Monthly cash flows generated from the HECM loans are used to service the HMBS obligations. The interest rate is based on the underlying HMBS rate with a range of 2.8% to 6.1% . Securitizations of Nonperforming HECM Loans From time to time, the Company securitizes its interests in non-performing reverse mortgages. The transactions provide investors with the ability to invest in a pool of both non-performing HECM loans secured by one-to-four-family residential properties and a pool of REO properties acquired through foreclosure of a deed in lieu of foreclosure in connection with HECM loans that are covered by FHA insurance. The transactions provide the Company with access to liquidity for the non-performing HECM loan portfolio, ongoing servicing fees, and potential residual returns. The transactions are structured as secured borrowings with the reverse mortgage loans included in the consolidated financial statements as reverse mortgage interests and the related financing included in other nonrecourse debt. Interest is accrued at a rate of 2.0% to 6.0% on the outstanding securitized notes and recorded as interest expense in consolidated statements of operations. The HECM securitizations are callable with expected weighted average lives of less than one to four years. The Company may re-securitize the previously called loans from earlier HECM securitizations to achieve a lower cost of funds. Nonrecourse Debt – Legacy Assets During November 2009, the Company completed the securitization of approximately $222 of Asset-Backed Securities (“ABS”), which was accounted for as a secured borrowing. This structure resulted in the Company carrying the securitized mortgage loans in its consolidated balance sheets and recognizing the asset-backed certificates acquired by third parties. The principal and interest on these notes are paid using the cash flows from the underlying mortgage loans, which serve as collateral for the debt. The interest rate paid on the outstanding securities is 7.5% , which is subject to an available funds cap. The total outstanding principal balance on the underlying mortgage loans serving as collateral for the debt was approximately $156 and $160 at March 31, 2019 and December 31, 2018 , respectively. The UPB on the outstanding loans were $26 and $29 at March 31, 2019 and December 31, 2018 , respectively, and the carrying value of the nonrecourse debt were $26 and $29 , respectively. Financial Covenants The Company’s borrowing arrangements and credit facilities contain various financial covenants which primarily relate to required tangible net worth amounts, liquidity reserves, leverage requirements, and profitability requirements. The Company was in compliance with its required financial covenants as of March 31, 2019 . The Company is required to maintain a minimum tangible net worth of at least $682 as of each quarter-end related to its outstanding Master Repurchase Agreements on its outstanding repurchase facilities. As of March 31, 2019 , the Company was in compliance with these minimum tangible net worth requirements.

Payables and Other Liabilities Payables and other liabilities consist of the following: Successor March 31, 2019 December 31, 2018 Loans subject to repurchase from Ginnie Mae $ 774 $ 266 Payables to servicing and subservicing investors 483 494 Operating lease liability 142 — Payables to GSEs and securitized trusts 57 105 MSR purchases payable including advances 30 182 Other Liabilities 489 496 Total payables and other liabilities $ 1,975 $ 1,543 Loans Subject to Repurchase from Ginnie Mae See Note 8, Other Assets , for a description of assets and liabilities related to loans subject to repurchase from Ginnie Mae. The amount as of March 31, 2019 includes $510 related to Pacific Union. Payables to Servicing and Subservicing Investors and Payables to GSEs and Securitized Trusts Payables to servicing and subservicing investors, GSEs and securitized trusts represent amounts due to investors, GSEs and securitized trusts in connection with loans serviced that are paid from collections of the underlying loans, insurance proceeds or proceeds from property disposal. Operating lease liabilities Operating lease liabilities are recognized as a result of adoption of ASC 842. See Note 7, Leases for additional information. MSR purchases payable including advances MSR purchases payable including advances represents the amounts owed to the seller in connection with the purchase of MSRs. Other Liabilities Other liabilities primarily include accrued bonus and payroll, accrued interest, accrued legal expenses, payable to insurance carriers and insurance cancellation reserves, derivative financial instruments, repurchase reserves, accounts payable and other accrued liabilities. Payables to insurance carriers and insurance cancellation reserves consist of insurance premiums received from borrower payments awaiting disbursement to the insurance carrier and/or amounts due to third-party investors on liquidated loans. See Note 9, Derivative Financial Instrument , for further details on derivative financial instruments. Successor Predecessor Repurchase Reserves Three Months Ended March 31, 2019 Three Months Ended March 31, 2018 Balance - beginning of period $ 8 $ 9 Provisions (1) 8 1 Releases — (1 ) Charge-offs — — Balance - end of period $ 16 $ 9 (1) Provision for the three months ended March 31, 2019 is primarily due to repurchase reserve liability assumed in connection with the acquisition of Pacific Union. See Note 2, Acquisitions for further information. The provision for repurchases represents an estimate of losses to be incurred on the repurchase of loans or indemnification of purchaser’s losses related to forward loans. Certain sale contracts and GSE standards require the Predecessor and subsequently the Company to repurchase a loan or indemnify the purchaser or insurer for losses if a borrower fails to make initial loan payments or if the accompanying mortgage loan fails to meet certain customary representations and warranties, such as the manner of origination, the nature and extent of underwriting standards. In the event of a breach of the representations and warranties, the Predecessor and subsequently the Company may be required to either repurchase the loan or indemnify the purchaser for losses it sustains on the loan. In addition, an investor may request that the Predecessor and subsequently the Company refund a portion of the premium paid on the sale of mortgage loans if a loan is prepaid within a certain amount of time from the date of sale. The Predecessor and the Company record a reserve for estimated losses associated with loan repurchases, purchaser indemnification and premium refunds. The provision for repurchase losses is charged against net gain on mortgage loans held for sale. A release of repurchase reserves is recorded when the Predecessor and Company’s assessment reveals that previously recorded reserves are no longer needed. A selling representation and warranty framework was introduced by the GSEs in 2013 and enhanced in 2014 that helps address concerns of loan sellers with respect to loan repurchase risk. Under the framework, a GSE will not exercise its remedies, including the issuance of repurchase requests, for breaches of certain selling representations and warranties if a mortgage meets certain eligibility requirements. For loans sold to GSEs on or after January 1, 2013, repurchase risk for Home Affordable Refinance Program (“HARP”) loans is lowered if the borrower stays current on the loan for 12 months and representation and warranty risks are limited for non-HARP loans that stay current for 36 months. The Company regularly evaluates the adequacy of repurchase reserves based on trends in repurchase and indemnification requests, actual loss experience, settlement negotiation, estimated future loss exposure and other relevant factors including economic conditions. Current loss rates have significantly declined attributable to stronger underwriting standards and due to the falloff of loans underwritten prior to mortgage loan crisis period prior to 2008. The Company believes its reserve balance as of March 31, 2019 is sufficient to cover loss exposure associated with repurchase contingencies.

Variable Interest Entities and Securitizations [Abstract]
Securitizations and Financings	12. Securitizations and Financings Variable Interest Entities (VIE) In the normal course of business, the Company enters into various types of on- and off-balance sheet transactions with special purpose entities (“SPEs”) determined to be VIEs, which primarily consist of securitization trusts established for a limited purpose. Generally, these SPEs are formed for the purpose of securitization transactions in which the Company transfers assets to an SPE, which then issues to investors various forms of debt obligations supported by those assets. The Company has determined that the SPEs created in connection with the (i) Nationstar Home Equity Loan Trust 2009-A, (ii) Nationstar Mortgage Advance Receivables Trust (NMART), (iii) Nationstar Agency Advance Financing Trust (NAAFT) and (iv) Nationstar Advance Agency Receivables Trust (NAART) should be consolidated as the Company is the primary beneficiary of each of these entities. Also, the Company consolidated four reverse mortgage SPEs as it is the primary beneficiary of each of these entities. These SPEs include the Nationstar HECM Loan Trusts. A summary of the assets and liabilities of the Company’s transactions with VIEs included in the Company’s consolidated financial statements is presented below.

Equity [Abstract]
Stockholders' Equity	13. Stockholders' Equity Upon the consummation of the Merger, the Company assumed and adopted the Nationstar Mortgage Holdings Inc. Second Amended and Restated 2012 Incentive Compensation Plan (“2012 Plan”), as may be amended, that offers equity-based awards to certain key employees of the Company, consultants, and non-employee directors. The equity-based awards include restricted stock units (“RSUs”) granted to employees. These awards are valued at the fair market value of the Company’s common stock on the grant date as defined in the 2012 Plan. During the three months ended March 31, 2019 and 2018 , certain employees of the Company and Predecessor were granted 1,873 thousand and 934 thousand RSUs, respectively. The stock awards generally vest in installments of 33.3% , 33.3% and 33.4% respectively on each of the first three anniversaries of the awards, provided that (i) the participant remains continuously employed with the Company during that time or (ii) the participant’s employment has terminated by reason of retirement. In addition, upon death, disability or generally a change in control of the Company, the unvested shares of an award will vest. The value of the stock awards is measured based on the market value of common stock of the Company or its Predecessor on the grant date. The Company and the Predecessor recorded $4 and $4 of expenses related to equity-based awards during the three months ended March 31, 2019 and 2018 , respectively.

Earnings Per Share [Abstract]
Earnings Per Share	14. Earnings Per Share The Company computes earnings per share using the two-class method, which is an earnings allocation formula that determines earnings per share for common stock and any participating securities according to dividends declared (whether paid or unpaid) and participation rights in undistributed earnings. The Series A Preferred Stock is considered participating securities because it has dividend rights determined on an as-converted basis in the event of Company’s declaration of a dividend or distribution for common shares. The following table sets forth the computation of basic and diluted net (loss) income per common share (amounts in millions, except per share amounts).

For the three months ended March 31, 2018 in the Predecessor period, the effective tax rate differed slightly from the statutory federal rate of 21% primarily due to permanent differences including executive compensation disallowed under Internal Revenue Code Section 162(m), favorable discrete adjustments in connection with the remediation of the Company’s uncertain tax position, and other recurring adjustments, such as state tax expense offset by excess tax benefit related to restricted share-based compensation.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	16. Fair Value Measurements Fair value is a market-based measurement, not an entity-specific measurement, and should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, a three-tiered fair value hierarchy has been established based on the level of observable inputs used in the measurement of fair value (e.g., Level 1 representing quoted prices for identical assets or liabilities in an active market; Level 2 representing values using observable inputs other than quoted prices included within Level 1; and Level 3 representing estimated values based on significant unobservable inputs). The following describes the methods and assumptions used by the Company in estimating fair values: Cash and Cash Equivalents, Restricted Cash (Level 1) – The carrying amount reported in the consolidated balance sheets approximates fair value. Mortgage Loans Held for Sale (Level 2) – The Company originates mortgage loans in the U.S. that it intends to sell into Fannie Mae, Freddie Mac and Ginnie Mae (collectively, the “Agencies”) MBS. Additionally, the Company holds mortgage loans that it intends to sell into the secondary markets via whole loan sales or securitizations. The Company measures newly originated prime residential mortgage loans held for sale at fair value. Mortgage loans held for sale are typically pooled together and sold into certain exit markets, depending upon underlying attributes of the loan, such as agency eligibility, product type, interest rate and credit quality. Mortgage loans held for sale are valued on a recurring basis using a market approach by utilizing either: (i) the fair value of securities backed by similar mortgage loans, adjusted for certain factors to approximate the fair value of a whole mortgage loan, including the value attributable to mortgage servicing and credit risk, (ii) current commitments to purchase loans or (iii) recent observable market trades for similar loans, adjusted for credit risk and other individual loan characteristics. As these prices are derived from market observable inputs, the Company classifies these valuations as Level 2 in the fair value disclosures. The Company may acquire mortgage loans held for sale from various securitization trusts for which it acts as servicer through the exercise of various clean-up call options as permitted through the respective pooling and servicing agreements. The Company has elected to account for these loans at the lower of cost or market. The Company classifies these valuations as Level 2 in the fair value disclosures. The Company may also purchase loans out of a Ginnie Mae securitization pool if that loan meets certain criteria, including being delinquent greater than 90 days. The Company has elected to carry these loans at fair value. See Note 6, Mortgage Loans Held for Sale and Investment , for more information. Mortgage Loans Held for Investment (Level 3) – Mortgage loans held for investment primarily consist of nonconforming or subprime mortgage loans that were transferred in 2009 from mortgage loans held for sale at fair value and which the Company intends to hold these loans to their maturities. The Company determines the fair value of loans held for investment, on a recurring basis, based on various underlying attributes such as market participants’ views, loan delinquency, recent observable loan pricing and sales for similar loans, individual loan characteristics and internal market evaluation. These internal market evaluations require the use of judgment by the Company and can have a significant impact on the determination of the loan’s fair value. As these fair values are derived from internally developed valuation models, using observable inputs, the Company classifies these valuations as Level 3 in the fair value disclosures. See Note 6, Mortgage Loans Held for Sale and Investment , for more information. Mortgage Servicing Rights – Fair Value (Level 3) – The Company estimates the fair value of its forward MSRs on a recurring basis using a process that combines the use of a discounted cash flow model and analysis of current market data to arrive at an estimate of fair value. The cash flow assumptions and prepayment assumptions used in the model are based on various factors, with the key assumptions being mortgage prepayment speeds, discount rates, ancillary revenues, earnings on escrows and costs to service. These assumptions are generated and applied based on collateral stratifications including product type, remittance type, geography, delinquency and coupon dispersion. These assumptions require the use of judgment by the Company and can have a significant impact on the fair value of the MSRs. Quarterly, management obtains third-party valuations to assess the reasonableness of the fair value calculations provided by the internal cash flow model. Because of the nature of the valuation inputs, the Company classifies these valuations as Level 3 in the fair value disclosures. See Note 3, Mortgage Servicing Rights and Related Liabilities , for more information. Advances and Other Receivables, Net (Level 3) - Advances and other receivables, net are valued at their net realizable value after taking into consideration the reserves. Advances have no stated maturity. Their net realizable value approximates fair value as the net present value based on discounted cash flow is not materially different from the net realizable value. Reverse Mortgage Interests, Net (Level 3) – The Company’s reverse mortgage interests are primarily comprised of HECM loans that are insured by FHA and guaranteed by Ginnie Mae upon securitization. Quarterly, the Company estimates fair value using discounted cash flows, obtained from a third-party, with the discount rate approximate that of similar financial instruments. Key assumptions within the model are based on market participant benchmarks and include discount rates, cost to service, weighted average life of the portfolio, and estimated servicing fee income. Discounted cash flows are applied based on collateral stratifications and include loan rate type, loan status (active vs. inactive), and securitization. Prices are also influenced from both internal models and other observable inputs. The Predecessor determined fair value for active reverse mortgage loans based on pricing of the recent securitizations with similar attributes and characteristics, such as collateral values and prepayment speeds and adjusted as necessary for differences. The related timing of these transactions allowed the pricing to consider the current interest rate risk exposures. The fair value of inactive reverse mortgage loans was established based upon a discounted par value of the loan derived from the Predecessor’s historical loss factors experience on foreclosed loans. Derivative Financial Instruments (Level 2) – The Company enters into a variety of derivative financial instruments as part of its hedging strategy and measures these instruments at fair value on a recurring basis in the consolidated balance sheets. The majority of these derivatives are exchange-traded or traded within highly active dealer markets. In order to determine the fair value of these instruments, the Company utilizes the exchange price or dealer market price for the particular derivative contract; therefore, these contracts are classified as Level 2. In addition, the Company enters into IRLCs and LPCs with prospective borrowers and other loan originators. These commitments are carried at fair value based on the fair value of underlying mortgage loans which are based on observable market data. The Company adjusts the outstanding IRLCs with prospective borrowers based on an expectation that it will be exercised and the loan will be funded. IRLCs and LPCs are recorded in derivative financial instruments in the consolidated balance sheets. These commitments are classified as Level 2 in the fair value disclosures, as the valuations are based on market observable inputs. The Company has entered into Eurodollar futures contracts as part of its hedging strategy. The futures contracts are measured at fair value on a recurring basis and classified as Level 2 in the fair value disclosures as the valuation is based on market observable data. See Note 9, Derivative Financial Instrument , for more information. Advance Facilities and Warehouse Facilities (Level 2) – As the underlying warehouse and advance finance facilities bear interest at a rate that is periodically adjusted based on a market index, the carrying amount reported on the consolidated balance sheets approximates fair value. See Note 10, Indebtedness , for more information. Unsecured Senior Notes (Level 1) – The fair value of unsecured senior notes, which are carried at amortized cost, is based on quoted market prices and is considered Level 1 from the market observable inputs used to determine fair value. See Note 10, Indebtedness , for more information. Nonrecourse Debt – Legacy Assets (Level 3) – The Company estimates fair value based on the present value of future expected discounted cash flows with the discount rate approximating current market value for similar financial instruments. These prices are derived from a combination of internally developed valuation models and quoted market prices, and are classified as Level 3. See Note 10, Indebtedness , for more information. Excess Spread Financing (Level 3) – The Company estimates fair value on a recurring basis based on the present value of future expected discounted cash flows with the discount rate approximating current market value for similar financial instruments. The cash flow assumptions and prepayment assumptions used in the model are based on various factors, with the key assumptions being mortgage prepayment speeds, average life, recapture rates and discount rate. As these prices are derived from a combination of internally developed valuation models and quoted market prices based on the value of the underlying MSRs, the Company classifies these valuations as Level 3 in the fair value disclosures. See Note 3, Mortgage Servicing Rights and Related Liabilities , for more information. Mortgage Servicing Rights Financing Liability (Level 3) - The Company estimates fair value on a recurring basis based on the present value of future expected discounted cash flows with the discount rate approximating current market value for similar financial instruments. The cash flow assumptions and prepayment assumptions used in the model are based on various factors, with the key assumptions being advance financing rates and annual advance recovery rates. As these assumptions are derived from internally developed valuation models based on the value of the underlying MSRs, the Company classifies these valuations as Level 3 in the fair value disclosures. See Note 3, Mortgage Servicing Rights and Related Liabilities , for more information. Participating Interest Financing (Level 2) – The Company estimates fair value based on the present value of future expected discounted cash flows with the discount rate approximating that of similar financial instruments. As the prices are derived from both internal models and other observable inputs, the Company classifies these valuations as Level 3 in the fair value disclosures. The Predecessor estimated the fair value using a market approach by utilizing the fair value of securities backed by similar participating interests in reverse mortgage loans. The Predecessor classified these valuations as Level 2 in the fair value disclosures. See Note 3, Mortgage Servicing Rights and Related Liabilities , and Note 10, Indebtedness , for more information. HECM Securitizations (Level 3) – The Company estimates fair value using a market approach by utilizing the fair value of executed HECM securitizations. Since the executed HECM securitizations are private placements, the Company classifies these valuations as Level 3 in the fair value disclosures. The Predecessor estimated fair value of the nonrecourse debt related to HECM securitization based on the present value of future expected discounted cash flows with the discount rate approximating that of similar financial instruments. As the prices are derived from both internal models and other observable inputs, the Predecessor classified this as Level 3 in the fair value disclosures. See Note 10, Indebtedness for more information.

Capital Requirements

Capital Requirements	3 Months Ended

Mortgage Banking [Abstract]
Capital Requirements	17. Capital Requirements Certain of the Company’s secondary market investors require minimum net worth (“capital”) requirements, as specified in the respective selling and servicing agreements. In addition, these investors may require capital ratios in excess of the stated requirements to approve large servicing transfers. To the extent that these requirements are not met, the Company’s secondary market investors may utilize a range of remedies ranging from sanctions, suspension or ultimately termination of the Company’s selling and servicing agreements, which would prohibit the Company from further originating or securitizing these specific types of mortgage loans or being an approved servicer. Among the Company’s various capital requirements related to its outstanding selling and servicing agreements, the most restrictive of these requires the Company to maintain a minimum adjusted net worth balance of $829 . As of March 31, 2019 , the Company was in compliance with its selling and servicing capital requirements.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	18. Commitments and Contingencies Litigation and Regulatory Matters The Company and its subsidiaries are routinely and currently involved in a significant number of legal proceedings, including, but not limited to, judicial, arbitration, regulatory and governmental proceeds related to matters that arise in connection with the conduct of Company’s business. The legal proceedings are at varying stages of adjudication, arbitration or investigation and are generally based on alleged violations of consumer protection, securities, employment, contract, tort, common law fraud and other numerous laws, including, without limitation, the Equal Credit Opportunity Act, Fair Debt Collection Practices Act, Fair Credit Reporting Act, Real Estate Settlement Procedures Act, National Housing Act, Homeowners Protection Act, Service Member’s Civil Relief Act, Telephone Consumer Protection Act, Truth in Lending Act, Financial Institutions Reform, Recovery, and Enforcement Act of 1989, unfair, deceptive or abusive acts or practices in violation of the Dodd-Frank Act, the Securities Act of 1933, the Securities Exchange Act of 1934, the Home Mortgage Disclosure Act, Title 11 of the United States Code (aka the “Bankruptcy Code”), False Claims Act and Making Home Affordable loan modification programs. In addition, along with others in its industry, the Company is subject to repurchase and indemnification claims and may continue to receive claims in the future, regarding alleged breaches of representations and warranties relating to the sale of mortgage loans, the placement of mortgage loans into securitization trusts or the servicing of mortgage loans securitizations. The Company is also subject to legal actions or proceedings related to loss sharing and indemnification provisions of its various acquisitions. Certain of the pending or threatened legal proceedings include claims for substantial compensatory, punitive and/or statutory damages or claims for an indeterminate amount of damages. The Company’s business is also subject to extensive examinations, investigations and reviews by various federal, state and local governmental, regulatory and enforcement agencies. The Company has historically had a number of open investigations with these agencies and that trend continues. The Company is currently the subject of various governmental or regulatory investigations, subpoenas, examinations and inquiries related to its residential loan servicing and origination practices, bankruptcy and collections practices, its financial reporting and other aspects of its businesses. These matters include investigations by the Consumer Financial Protection Bureau (the “CFPB”), the Securities and Exchange Commission, the Executive Office of the United States Trustees, the Department of Justice, the Office of the Special Inspector General for the Troubled Asset Relief Program, the U.S. Department of Housing and Urban Development, the multi-state committee of mortgage banking regulators and various State Attorneys General. These specific matters and other pending or potential future investigations, subpoenas, examinations or inquiries may lead to administrative, civil or criminal proceedings or settlements, and possibly result in remedies including fines, penalties, restitution, or alterations in the Company’s business practices, and in additional expenses and collateral costs. Responding to these matters requires the Company to devote substantial resources, resulting in higher costs and lower net cash flows. For example, the Company continues to progress towards resolution of certain legacy regulatory matters involving examination findings for alleged violations of certain laws related to the Company’s business practices. The Company has been in discussions with the multi-state committee of mortgage banking regulators and various State Attorneys General concerning a potential resolution of their investigations. The Company is continuing to cooperate with all parties. In connection with these discussions, the Company previously recorded an accrual. These discussions may not result in a settlement of the matter; furthermore, any such settlement may exceed the amount accrued as of March 31, 2019 . Moreover, if the discussions do not result in a settlement, the regulators and State Attorneys General may seek to exercise their enforcement authority through litigation or other proceedings and seek injunctive relief, damages, restitution and civil monetary penalties, which could have a material adverse effect on the Company’s business, reputation, financial condition and results of operations. Further, on April 24, 2018, the CFPB notified Nationstar that, in accordance with the CFPB’s discretionary Notice and Opportunity to Respond and Advise (“NORA”) process, the CFPB’s Office of Enforcement is considering whether to recommend that the CFPB take enforcement action against the Company, alleging violations of the Real Estate Settlement Procedures Act, the Consumer Financial Protection Act, and the Homeowners Protection Act, which stems from a 2014 examination. The purpose of a NORA letter is to provide a party being investigated an opportunity to present its position to the CFPB before an enforcement action may be recommended or commenced. The CFPB may seek to exercise its enforcement authority through settlement, administrative proceedings or litigation and seek injunctive relief, damages, restitution and civil monetary penalties, which could have a material adverse effect on the Company’s business, reputation, financial condition and results of operations. The Company has not recorded an accrual related to this matter as of March 31, 2019 because it does not believe that the possible loss or range of loss arising from any such action is estimable. The Company is continuing to cooperate with the CFPB. Similarly, the Company is in discussions with the Executive Office of the United States Trustees concerning certain legacy issues with respect to bankruptcy servicing practices. In connection with these discussions, the Company is undertaking certain voluntary remediation activities with respect to loans at issue in these matters. While the Company and the Executive Office of the United States Trustees are engaged in discussions to potentially resolve these issues, there is no guarantee a resolution will occur. Moreover, if the discussions do not result in a resolution, the Executive Office of the United States Trustees may seek redress through litigation or other proceedings and seek injunctive relief, damages and restitution in addition to the remediation activities, which could have a material adverse effect on the Company’s business, reputation, financial condition and results of operations. However, the Company believes it is premature to predict the potential outcome or to estimate the financial impact to the Company in connection with any potential action or settlement arising from this matter, including the voluntary remediation activities undertaken and to be undertaken by the Company. In addition, the Company is a defendant in a class action proceeding originally filed in state court in March 2012 and then removed to the United States District Court for the Eastern District of Washington under the caption Laura Zamora Jordan v. Nationstar Mortgage LLC. The suit was filed on behalf of a class of Washington borrowers and challenges property preservation measures the Company took, as loan servicer, after the borrowers defaulted and the Company’s vendors determined that the borrowers had vacated or abandoned their properties. The case raises claims for (i) common law trespass, (ii) statutory trespass, and (iii) violation of Washington’s Consumer Protection Act, and seeks recovery of actual, statutory, and treble damages, as well as attorneys’ fees and litigation costs. On July 25, 2018, the Company entered into a settlement agreement to resolve this matter. The parties are currently seeking approval of the final settlement from the court. The Company is pursuing reimbursement of the settlement payment from the owners of the loans it serviced, but there can be no assurance that the Company would prevail with any claims for reimbursement. The Company is a defendant in a proceeding filed on January 2, 2018 in the U.S. District Court for the Northern District of California under the caption Collateral Analytics LLC v. Nationstar Mortgage LLC et al. The plaintiff alleges that the Company misappropriated plaintiff’s intellectual property for the purpose of replicating plaintiff’s products. The case raises federal and state law claims for misappropriation of trade secrets and breach of contract and seeks an award of actual damages, unjust enrichment, lost profits and/or a reasonable royalty, exemplary damages and injunctive relief preventing further misuse or disclosure of plaintiff’s intellectual property. The Company believes it has meritorious defenses and will vigorously defend itself in this matter. The Company is also a defendant in a proceeding filed on October 23, 2015 in the U.S. District Court for the Central District of California under the caption Alfred Zaklit and Jessy Zaklit, individually and on behalf of all others similarly situated v. Nationstar Mortgage LLC et al. The plaintiff alleges that the Company improperly recorded telephone calls without the knowledge or consent of borrowers in violation of the California Penal Code. On July 24, 2017, the court certified a class comprised of California borrowers who, from October 2014 to May 2016, participated in outbound telephone conversations with the Company’s employees who recorded the conversations without first informing the borrowers that the conversations were being recorded. The class seeks statutory damages and attorney’s fees. On September 10, 2018, the Company reached an agreement in principal to settle this matter, and the parties are currently seeking approval of the settlement from the court. The Company seeks to resolve all legal proceedings and other matters in the manner management believes is in the best interest of the Company and contests liability, allegations of wrongdoing and, where applicable, the amount of damages or scope of any penalties or other relief sought as appropriate in each pending matter. The Company has entered into agreements with a number of entities and regulatory agencies that toll applicable limitations periods with respect to their claims. On at least a quarterly basis, the Company assesses its liabilities and contingencies in connection with outstanding legal and regulatory and governmental proceedings utilizing the latest information available. Where available information indicates that it is probable, a liability has been incurred, and the Company can reasonably estimate the amount of the loss, an accrued liability is established. The actual costs of resolving these proceedings may be substantially higher or lower than the amounts accrued. As a legal matter develops, the Company, in conjunction with any outside counsel handling the matter, evaluates on an ongoing basis whether such matter presents a loss contingency that is both probable and estimable. If, at the time of evaluation, the loss contingency is not both probable and reasonably estimable, the matter will continue to be monitored for further developments that would make such loss contingency both probable and reasonably estimable. Once the matter is deemed to be both probable and reasonably estimable, the Company will establish an accrued liability and record a corresponding amount to legal-related expense. The Company will continue to monitor the matter for further developments that could affect the amount of the accrued liability that has been previously established. Legal-related expense for the Company and Predecessor, which includes legal settlements and the fees paid to external legal service providers, of $11 and $4 for the three months ended March 31, 2019 and 2018, respectively, was included in general and administrative expenses on the consolidated statements of operations. For a number of matters for which a loss is probable or reasonably possible in future periods, whether in excess of a related accrued liability or where there is no accrued liability, the Company may be able to estimate a range of possible loss. In determining whether it is possible to provide an estimate of loss or range of possible loss, the Company reviews and evaluates its material legal matters on an ongoing basis, in conjunction with any outside counsel handling the matter. For those matters for which an estimate is possible, management currently believes the aggregate range of reasonably possible loss is $14 to $36 in excess of the accrued liability (if any) related to those matters as of March 31, 2019 . This estimated range of possible loss is based upon currently available information and is subject to significant judgment, numerous assumptions and known and unknown uncertainties. The matters underlying the estimated range will change from time to time, and actual results may vary substantially from the current estimate. Those matters for which an estimate is not possible are not included within the estimated range. Therefore, this estimated range of possible loss represents what management believes to be an estimate of possible loss only for certain matters meeting these criteria. It does not represent the Company’s maximum loss exposure and the Company cannot provide assurance that its litigations reserves will not need to be adjusted in the future. Thus, the Company’s exposure and ultimate losses may be higher, possibly significantly so, than the amounts accrued or this aggregate amount. In the Company’s experience, legal proceedings are inherently unpredictable. One or more of the following factors frequently contribute to this inherent unpredictability: the proceeding is in its early stages; the damages sought are unspecified, unsupported or uncertain; it is unclear whether a case brought as a class action will be allowed to proceed on that basis or, if permitted to proceed as a class action, how the class will be defined; the other party is seeking relief other than or in addition to compensatory damages (including, in the case of regulatory and governmental investigations and inquiries, the possibility of fines and penalties); the matter presents meaningful legal uncertainties, including novel issues of law; the Company has not engaged in meaningful settlement discussions; discovery has not started or is not complete; there are significant facts in dispute; predicting possible outcomes depends on making assumptions about future decisions of courts or governmental or regulatory bodies or the behavior of other parties; and there are a large number of parties named as defendants (including where it is uncertain how damages or liability, if any, will be shared among multiple defendants). Generally, the less progress that has been made in the proceedings or the broader the range of potential results, the harder it is for the Company to estimate losses or ranges of losses that is reasonably possible the Company could incur. Based on current knowledge, and after consultation with counsel, management believes that the current legal accrued liability within payables and accrued liabilities, is appropriate, and the amount of any incremental liability arising from these matters is not expected to have a material adverse effect on the consolidated financial condition of the Company, although the outcome of such proceedings could be material to the Company’s operating results and cash flows for a particular period depending, on among other things, the level of the Company’s revenues or income for such period. However, in the event of significant developments on existing cases, it is possible that the ultimate resolution, if unfavorable, may be material to the Company’s consolidated financial statements. Other Loss Contingencies As part of the Company’s ongoing operations, it acquires servicing rights of forward and reverse mortgage loan portfolios that are subject to indemnification based on the representations and warranties of the seller. From time to time, the Company will seek recovery under these representations and warranties for incurred costs. The Company believes all balances sought from sellers recorded in advances and other receivables and reverse mortgage interests represent valid claims. However, the Company acknowledges that the claims process can be prolonged due to the required time to perfect claims at the loan level. Because of the required time to perfect or remediate these claims, management relies on the sufficiency of documentation supporting the claim, current negotiations with the counterparty and other evidence to evaluate whether a reserve is required for non-recoverable balances. In the absence of successful negotiations with the seller, all amounts claimed may not be recovered. Balances may be written-off and charged against earnings when management identifies amounts where recoverability from the seller is not likely. As of March 31, 2019 , the Company believes all recorded balances for which recovery is sought from the seller are valid claims, and no evidence suggests additional reserves are warranted at this time. Loan and Other Commitments The Company enters into IRLCs with prospective borrowers whereby the Company commits to lend a certain loan amount under specific terms and interest rates to the borrower. The Company also enters into LPCs with prospective sellers. These loan commitments are treated as derivatives and are carried at fair value. See Note 9, Derivative Financial Instrument , for more information. The Company and the Predecessor had certain reverse MSRs, reverse MSLs and reverse mortgage loans related to approximately $27,014 and $28,415 of UPB in reverse mortgage loans as of March 31, 2019 and December 31, 2018 , respectively. As servicer for these reverse mortgage loans, among other things, the Company is obligated to fund borrowers’ draws to the loan customers as required in accordance with the loan agreement. As of March 31, 2019 and December 31, 2018 , the Company’s maximum unfunded advance obligation to fund borrower draws related to these MSRs and loans was approximately $3,005 and $3,128 , respectively. Upon funding any portion of these draws, the Company and the Predecessor expect to securitize and sell the advances in transactions that will be accounted for as secured borrowings.

Segment Reporting [Abstract]
Business Segment Reporting	19. Business Segment Reporting Upon consummation of the Merger with Nationstar, the Company has identified four reportable segments: Servicing, Originations, Xome and Corporate and other. The Company’s segments are based upon the Company’s organizational structure, which focuses primarily on the services offered. Corporate functional expenses are allocated to individual segments based on the actual cost of services performed based on direct resource utilization, estimate of percentage use for shared services or headcount percentage for certain functions. Facility costs are allocated to individual segments based on cost per headcount for specific facilities utilized. Group insurance costs are allocated to individual segments based on global cost per headcount. Non-allocated corporate expenses include the administrative costs of executive management and other corporate functions that are not directly attributable to Company’s operating segments. Revenues generated on inter-segment services performed are valued based on similar services provided to external parties. The following tables present financial information by segment.

Transactions with Affiliates

Transactions with Affiliates	3 Months Ended

Related Party Transactions [Abstract]
Transactions with Affiliates	21. Transactions with Affiliates Nationstar previously entered into arrangements with Fortress Investment Group (“Fortress”), its subsidiaries managed funds, or affiliates for purposes of financing the Company’s MSR acquisitions and performing services as a subservicer. Prior to the Merger with Nationstar on July 31, 2018, an affiliate of Fortress held a majority of the outstanding common shares of the Predecessor. Subsequent to the Merger, Fortress is no longer an affiliate of the Company. Refer to Note 2, Acquisitions , for additional information. The following summarizes the Predecessor’s transactions with affiliates of Fortress prior to the Merger on July, 31 2018. New Residential Excess Spread Financing The Predecessor has entered into several agreements with certain entities managed by New Residential, in which New Residential and/or certain funds managed by Fortress own an interest (each a “New Residential Entity”). The Predecessor sold to the related New Residential Entity the right to receive a portion of the excess cash flow generated from certain acquired MSRs after a receipt of a fixed base servicing fee per loan. The Predecessor, as the servicer of the loans, retains all ancillary revenues and the remaining portion of the excess cash flow after payment of the fixed base servicing fee and also provides all advancing functions for the portfolio. The related New Residential Entity does not have prior or ongoing obligations associated with these MSR portfolios. Should the Company refinance any loan in such portfolios, subject to certain limitations, the Company will be required to transfer the new loan or a replacement loan of similar economic characteristics into the portfolios. The new or replacement loan will be governed by the same terms set forth in the agreements described above. The fees paid to New Residential Entity by the Predecessor totaled $53 during the three months ended March 31, 2018 , which were recorded as a reduction to servicing fee revenue, net. Mortgage Servicing Rights Financing From December 2013 through June 2014, the Predecessor entered into agreements to sell a contractually specified base fee component of certain MSRs and servicing advances under specified terms to a joint venture capitalized by New Residential and certain unaffiliated third-parties. The Company continues to be the named servicer, and, for accounting purposes, ownership of the mortgage servicing rights continues to reside with the Company. Accordingly, the Company accounts for the MSRs and the related MSRs financing liability on its consolidated balance sheets. The Company will continue to sell future servicing advances to New Residential. The Predecessor did not enter into any additional supplemental agreements with these affiliates in 2018 . Subservicing and Servicing In January 2017, the Predecessor entered into a subservicing agreement with a subsidiary of New Residential. The Predecessor earned $19 of subservicing fees and other subservicing revenues during the three months ended March 31, 2018 . In May 2014, the Predecessor entered into a servicing arrangement with New Residential whereby the Predecessor services residential mortgage loans acquired by New Residential and/or its various affiliates and trust entities. For the three months ended March 31, 2018 , the Predecessor recognized approximately $1 related to these service arrangements.

Nature of Business and Basis _2

Nature of Business and Basis of Presentation (Policies)	3 Months Ended
	Mar. 31, 2019
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation For the purpose of financial statement presentation, Mr. Cooper was determined to be the accounting acquirer in the Merger, and Nationstar’s assets and liabilities were recorded at estimated fair value as of the acquisition date. Mr. Cooper’s interim consolidated financial statements for periods following the Merger closing are labeled “Successor” and reflect the acquired assets and liabilities from Nationstar. Under Securities and Exchange Commission (“SEC”) rules, when a registrant succeeds to substantially all of the business of another entity and the registrant’s own operations before the succession appear insignificant relative to the operations assumed or acquired, the registrant is required to present financial information for the acquired entity (the “Predecessor”) for all comparable periods being presented before the acquisition. Due to the acquisition, the Predecessor and Successor financial statements have been prepared on different basis of accounting and are therefore not comparable. Pursuant to the Merger, Nationstar is considered the predecessor company. Therefore, the Company is providing additional information in the accompanying unaudited condensed consolidated financial statements regarding Nationstar’s business for periods prior to July 31, 2018. The predecessor company financial information in this report is labeled “Predecessor” in these consolidated interim financial statements. The consolidated interim financial statements of the Company and Predecessor have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the SEC. Accordingly, the financial statements do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Reports on Form 10-K for the year ended December 31, 2018 . Upon the consummation of the Merger, the Company adopted the significant accounting policies that were implemented by Nationstar and applied to the Predecessor’s financial statements, as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. The interim consolidated financial statements are unaudited; however, in the opinion of management, all adjustments, consisting of normal recurring items, considered necessary for a fair presentation of the results of the interim periods have been included. Dollar amounts are reported in millions, except per share data and other key metrics, unless otherwise noted. The Company evaluated subsequent events through the date these interim consolidated financial statements were issued.
Basis of Consolidation	Basis of Consolidation The basis of consolidation described below was adopted by Nationstar and applied to the Predecessor financial statements for the periods impacted by the adoption. The Successor’s financial statements reflect the adoption of such standards. The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries, other entities in which the Company has a controlling financial interest and those variable interest entities (“VIE”) where the Company’s wholly-owned subsidiaries are the primary beneficiaries. Assets and liabilities of VIEs and their respective results of operations are consolidated from the date that the Company became the primary beneficiary through the date the Company ceases to be the primary beneficiary. The Company applies the equity method of accounting to investments where it is able to exercise significant influence, but not control, over the policies and procedures of the entity and owns less than 50% of the voting interests. Investments in certain companies over which the Company does not exert significant influence are accounted for as cost method investments. Intercompany balances and transactions on consolidated entities have been eliminated.
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates due to factors such as adverse changes in the economy, changes in interest rates, secondary market pricing for loans held for sale and derivatives, strength of underwriting and servicing practices, changes in prepayment assumptions, declines in home prices or discrete events adversely affecting specific borrowers, and such differences could be material.
Recent Accounting Guidance Adopted and Not Yet Adopted	Recent Accounting Guidance Adopted Accounting Standards Update No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), No.2018-10, Codification Improvements to Topic 842, Leases (“ASU 2018-10”), and No. 2018-11, Leases (Topic 842): Targeted Improvements (“ASU 2018-11”), primarily impact lessee accounting by requiring the recognition of a right-of-use asset and a corresponding lease liability on the balance sheet for long-term lease agreements. ASU 2016-02 was effective for the Company on January 1, 2019. ASU 2016-02 provides for a modified retrospective transition approach requiring lessees to recognize and measure leases on the balance sheet at the beginning of either the earliest period presented or as of the beginning of the period of adoption with the option to elect certain practical expedients. The Company has elected to apply ASU 2016-02 as of the beginning of the period of adoption (January 1, 2019) and has not restated comparative periods. The Company elected the package of practical expedients, which, among other items, permits the Company not to reassess under the new standard its prior conclusions about lease identification, lease classification and initial direct costs. The Company also elected the short-term lease recognition exemption for all leases that qualify. Under this practical expedient, for those leases that qualify, the Company does not recognize right-of-use (“ROU”) assets or lease liabilities, which includes not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition. The Company also elected the practical expedient to not separate lease and non-lease components for all of our leases. The Company did not elect the use-of-hindsight practical expedient. As a result of implementing ASU 2016-02, the Company recognized an operating lease ROU asset of $114 and an operating lease liability of $124 on January 1, 2019, with no impact on its consolidated statement of operations. There was no cumulative-effect adjustment to the opening balance of accumulated deficit as a result of the adoption of this standard. The ROU asset and operating lease liability are recorded in other assets, and payables and other liabilities, respectively, in the consolidated balance sheets. See Note 7, Leases for additional information. Accounting Standards Update No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40 - Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract " (“ASU 2018-15”) aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). ASU 2018-15 will be effective for the Company on January 1, 2020. Early adoption is permitted, including adoption in any interim period. In the first quarter of 2019, the Company early adopted ASU 2018-15. The standard did not have a material impact to the Company’s consolidated financial statements. Recent Accounting Guidance Not Yet Adopted Accounting Standards Update No. 2016-13, Financial Instruments - Credit Losses (Topic 326) (“ASU 2016-13”), requires expected credit losses for financial instruments held at the reporting date to be measured based on historical experience, current conditions and reasonable and supportable forecasts. The update eliminates the probable initial recognition threshold in current GAAP and instead reflects an entity’s current estimate of all expected credit losses. Previously, when credit losses were measured under GAAP, an entity generally only considered past events and current conditions in measuring the incurred loss. ASU 2016-13 is effective for interim periods beginning after December 15, 2019. The Company is currently evaluating the potential impact of ASU 2016-13 on its consolidated financial statements. Accounting Standards Update No. 2018-13, Fair Value Measurement (Topic 820) - Changes to the Disclosure Requirements for Fair Value Measurement , (“ASU 2018-13”) removes the requirement to disclose the amount of and reasons for transfers between Level 1 and Level 2 fair value measurement methodologies, the policy for timing of transfers between levels and the valuation processes for Level 3 fair value measurements. It also adds a requirement to disclose changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level 3 measurements. For certain unobservable inputs, entities may disclose other quantitative information in lieu of the weighted average if the other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. ASU 2018-13 will be effective for the Company on January 1, 2020. The Company is currently evaluating the potential impact of ASU 2018-13 on its consolidated financial statements.
