The Company and its Subsidiarie

Accounting Policies [Abstract]
The Company and its Subsidiaries	Note 1: The Company and its Subsidiaries WMIH Corp. WMIH Corp. (“WMIH”) is a corporation duly organized and existing under the laws of the State of Delaware. On May 11, 2015, WMIH merged with its parent corporation, WMI Holdings Corp., a Washington corporation (“WMIHC”), with WMIH as the surviving corporation in the merger (the “Merger”). The Merger occurred as part of the reincorporation of WMIHC from the State of Washington to the State of Delaware effective May 11, 2015 (the “Reincorporation Date”). WMIH, formerly known as WMIHC and Washington Mutual, Inc. (“WMI”), is the direct parent of WM Mortgage Reinsurance Company, Inc., a Hawaii corporation (“WMMRC”), and WMI Investment Corp., a Delaware corporation (“WMIIC”). Since the emergence from bankruptcy on March 19, 2012, our business activities consist of operating WMMRC’s legacy reinsurance business in runoff mode. In addition, we are actively seeking acquisition opportunities across a broad array of industries with a specific focus in the financial services industry, including targets with consumer finance, specialty finance, leasing and insurance operations. As of December 31, 2016, WMIH was authorized to issue up to 3,500,000,000 shares of common stock, and up to 10,000,000 shares of preferred stock (in one or more series), in each case with a par value of $0.00001 per share. As of December 31, 2016 and December 31, 2015, 206,380,800 and 206,168,035 shares, respectively, of WMIH’s common stock were issued and outstanding. As of December 31, 2016 and December 31, 2015, 1,000,000 shares of WMIH’s Series A Convertible Preferred Stock (the “Series A Preferred Stock”) were issued and outstanding. As of December 31, 2016 and December 31, 2015, 600,000 shares of WMIH’s 3% Series B Convertible Preferred Stock (the “Series B Preferred Stock”) were issued and outstanding. WMMRC WMMRC is a wholly-owned subsidiary of WMIH. Prior to August 2008 (at which time WMMRC became a direct subsidiary of WMI), WMMRC was a wholly-owned subsidiary of FA Out-of-State Holdings, Inc., a second-tier subsidiary of Washington Mutual Bank (“ WMMRC was originally organized to reinsure private mortgage insurance risk for seven primary mortgage insurers then offering private mortgage insurance on loans originated or purchased by former subsidiaries of WMI. The seven primary mortgage insurers are United Guaranty Residential Insurance Company (“UGRIC”), Genworth Mortgage Insurance Corporation (“GMIC”), Mortgage Guaranty Insurance Corporation (“MGIC”), PMI Mortgage Insurance Company (“PMI”), Radian Guaranty Incorporated (“Radian”), Republic Mortgage Insurance Company (“RMIC”) and Triad Guaranty Insurance Company (“Triad”). Due to the then deteriorating performance in the mortgage guarantee markets and the closure and receivership of WMB, the reinsurance agreements with each of the primary mortgage insurers were terminated or placed into runoff during 2008. The agreements with UGRIC and Triad were placed into runoff effective May 31, 2008. The agreements with all other primary mortgage insurers were placed into runoff effective September 26, 2008. As a result, effective September 26, 2008, WMMRC’s continuing operations consisted solely of the runoff of coverage associated with mortgages placed with the primary mortgage carriers prior to September 26, 2008. In runoff, an insurer generally writes no new business but continues to service its obligations under in force policies and otherwise continues as a licensed insurer. Management does not believe any additional adjustments to the carrying values of assets and liabilities, which were recorded at fair market value as a result of fresh start accounting as of March 19, 2012, are required as a result of WMMRC’s runoff status. The reinsurance agreements with Triad, PMI, and UGRIC were commuted on August 31, 2009, October 2, 2012 and April 3, 2014, respectively, and the related trust assets were distributed in accordance with the commutation agreements. As a result, WMMRC’s current continuing operations consist solely of the runoff of coverage associated with mortgages placed with four remaining carriers; GMIC, MGIC, Radian and RMIC. WMIIC WMIIC does not currently have any operations and is fully eliminated upon consolidation.

Accounting Policies [Abstract]
Significant Accounting Policies	Note 2: Significant Accounting Policies Basis of Presentation WMIH resumed timely filing of all periodic reports for a reporting company under the Securities Exchange Act of 1934, as amended, for all periods after emergence from bankruptcy on March 19, 2012 (the “Effective Date”). All significant intercompany transactions and balances have been eliminated in preparing the consolidated financial statements. Use of Estimates The preparation of financial statements in conformity with Generally Accepted Accounting Principles in the United States (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Management has made significant estimates in certain areas, including valuing certain financial instruments, other assets and liabilities, the determination of the contingent risk liabilities, and in determining appropriate insurance reserves. Actual results could differ substantially from those estimates. Fair Value of Certain Financial Instruments Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Generally, for assets that are reported at fair value, the Company uses quoted market prices or valuation models to estimate their fair value. These models incorporate inputs such as forward yield curves, market volatilities and pricing spreads, utilizing market-based inputs where readily available. The degree of management judgment involved in estimating the fair value of a financial instrument or other asset is dependent upon the availability of quoted market prices or observable market inputs. For financial instruments that are actively traded in the marketplace or whose values are based on readily available market value data, little judgment is necessary when estimating the instrument’s fair value. When observable market prices and data are not readily available, significant management judgment often is necessary to estimate fair value. In those cases, different assumptions could result in significant changes in valuation. The Company classifies fixed-maturity investments as trading securities, which are recorded at fair value. As such, changes in unrealized gains and losses on investments held at the balance sheet date are recognized and reported as a component of net investment income on the consolidated statements of operations. The Company believes fair value provides better matching of investment earnings to potential cash flow generated from the investment portfolio and reduces subjectivity related to evaluating other-than-temporary impairment on the Company’s investment portfolio. The carrying value of cash and cash equivalents, restricted cash, accounts payable and accrued liabilities approximate their respective fair values due to their short-term nature. The carrying value of the loss contract reserve approximates its fair value and is based on valuation methodologies using discounted cash flows at interest rates which approximate the Company’s weighted-average cost of capital. The carrying value of the derivative embedded conversion feature of the Series B Preferred Stock is adjusted to its fair value as determined using Level 3 inputs described below under fair value measurement. The carrying value of notes payable approximates fair value based on time to maturity, underlying collateral, and prevailing interest rates. Fair Value Measurement The Company’s estimates of fair value for financial assets and financial liabilities are based on the framework established in the Financial Accounting Standards Board Fair Value Measurements and Disclosures accounting guidance. The framework is based on the inputs used in valuation and requires that observable inputs be used in the valuations when available. The disclosure of fair value estimates in the fair value accounting guidance hierarchy is based on whether the significant inputs into the valuation are observable. In determining the level of the hierarchy in which the estimate is disclosed, the highest priority is given to unadjusted quoted prices in active markets and the lowest priority to unobservable inputs that reflect the Company’s significant market assumptions. The three levels of the hierarchy are as follows: Level 1—Inputs to the valuation methodology are quoted prices for identical assets or liabilities traded in active markets. Level 2—Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and market corroborated inputs. Level 3—Valuations based on models where significant inputs are not observable. The unobservable inputs reflect the Company’s own assumptions about the inputs that market participants would use. Fair values are based on quoted market prices when available (Level 1). The Company receives the quoted market prices from a third party, nationally recognized pricing service. When quoted prices are not available, the Company utilizes a pricing service to determine an estimate of fair value. The fair value is generally estimated using current market inputs for similar financial instruments with comparable terms and credit quality, commonly referred to as matrix pricing (Level 2). These valuation techniques involve some level of management estimation and judgment. The Company recognizes transfers between levels in the fair value hierarchy at the end of the reporting period. Fixed-Maturity Securities Fixed-maturity securities consist of U.S. Treasury securities, obligations of U.S. government sponsored agencies, and domestic and foreign corporate debt securities. Fixed-maturity securities held in trust are for the benefit of the primary insurers as more fully described in Note 3: Insurance Activity. Investments in fixed-maturity securities are reported at their estimated fair values and are classified as trading securities in accordance with applicable accounting guidance. Realized gains and losses on the sale of fixed-maturity securities are determined using the specific identification method and are reported as a component of net investment income within the consolidated statements of operations. Investments Held in Trust Investments held in trust consist of cash equivalents, which include highly liquid overnight money market instruments, and fixed-maturity securities which are held in trust for the benefit of the primary insurers as more fully described in Note 3: Insurance Activity and Note 4: Investment Securities, and are subject to the restrictions on distribution of net assets of subsidiaries as described below. Third Party Restrictions on Distribution of Net Assets of Wholly-Owned Subsidiaries The net assets of WMMRC are subject to restrictions on distribution from multiple sources including the primary insurers who have approval control of distributions from the trust, the Insurance Division of the State of Hawaii who has approval authority over distributions or intercompany advances, and additional restrictions as described in Note 7: Notes Payable. Premium Recognition Premiums assumed are earned on a daily pro-rata basis over the underlying policy terms. Premiums assumed relating to the unexpired portion of policies in force at the balance sheet date are recorded as unearned premiums. Unearned premiums also include a reserve for post default premium reserves. Post default premium reserves occur when a loan is in a default position and the servicer continues to advance the premiums. If the loan ultimately goes to claim, the premiums advanced during the period of default are subject to recapture. The Company records a post default premium reserve based on information provided by the underlying mortgage insurers when they provide information on the post default premium reserve separately from other reserves. The change in the post default premium reserve is reflected as a reduction or increase, as the case may be, in premiums assumed. The Company has recorded unearned premiums totaling $0.3 million and $0.8 million as of December 31, 2016 and December 31, 2015, respectively. The Company recognizes premium deficiencies when there is a probable loss on an insurance contract. Premium deficiencies are recognized if the sum of the present value of expected losses and loss adjustment expenses, unamortized deferred acquisition costs, and maintenance costs, excluding intercompany charges, exceed expected future unearned premiums and anticipated investment income. Premium deficiency reserves have been recorded totaling $0.3 million and $0.8 million as of December 31, 2016 and December 31, 2015, respectively. Due to the runoff nature of the WMMRC business, the intercompany maintenance costs were excluded from the computation of premium deficiencies during the current period and will also be excluded during future periods. The Company’s premium deficiency analysis was performed on a single book basis and includes all book years and reinsurance treaties aggregated together using assumptions based on the actuarial best estimates at the balance sheet date. The calculation for premium deficiency requires significant judgment and includes estimates of future expected premiums, claims, loss adjustment expenses and investment income as of the balance sheet date. To the extent ultimate losses are higher or premiums are lower than estimated, additional premium deficiency reserves may be required in the future. Cash and Cash Equivalents Cash and cash equivalents include cash on hand, amounts due from banks, U.S. Treasury bills and overnight investments. Except as described above in Investments Held in Trust, the Company considers all amounts that are invested in highly liquid overnight money market instruments to be cash equivalents. The Federal Deposit Insurance Corporation (“FDIC”) Restricted Cash Restricted cash includes (i) amounts held for the express purposes of paying principal, interest and related fees on the Runoff Notes (as defined in Note 7: Notes Payable) pursuant to the terms of the Indentures (as defined in Note 7: Notes Payable) and (ii) proceeds of the Series B Preferred Stock offering held in escrow. Ceding Commission Expense The Company is required to pay a ceding commission to certain primary insurers pursuant to certain reinsurance agreements. Losses and Loss Adjustment Reserves The losses and loss adjustment reserve includes case basis estimates of reported losses and supplemental amounts for incurred but not reported losses (“IBNR”). A default is considered the incident (e.g., the failure to make timely payment of mortgage payments) that may give rise to a claim for mortgage insurance. In establishing the losses and loss adjustment reserve, the Company based its estimates primarily on the ceded loss and loss adjustment reserves as provided by the primary mortgage guaranty carriers. WMMRC has recorded reserves at the ceded case reserves and IBNR levels established and reported by the primary mortgage guaranty carriers as of December 31, 2016 and December 31, 2015, respectively. Management believes that the recorded aggregate liability for unpaid losses and loss adjustment expenses at period end represents the Company’s best estimate, based upon the available data, of the amount necessary to cover the current cost of losses. However, due to the inherent uncertainty arising from fluctuations in the persistency rate of mortgage insurance claims, the Company’s size and lack of prior operating history, external factors such as future changes in regional or national economic conditions, judicial decisions, federal and state legislation related to mortgage restructuring and foreclosure restrictions, claims denials and coverage rescissions by primary carriers and other factors beyond the Company’s control, it is not presently possible to determine whether actual loss experience will conform to the assumptions used in determining the estimated amounts for such liability at the balance sheet date. Accordingly, the ultimate liability could be significantly higher or lower, as the case may be, than the amount indicated in the financial statements and there can be no assurance that the reserve amounts recorded will be sufficient. As adjustments to these estimates become necessary, such adjustments are reflected in current operations. Loss Contract Reserves A loss contract reserve relating to contractual obligations of WMMRC was established at March 19, 2012 as a result of applying fresh start accounting and in compliance with Accounting Standards Codification (“ASC”) 805-10-55-21 (b) (1) which defines a loss contract as a “contract in which the unavoidable costs of meeting the obligations under the contract exceed the economic benefits expected to be received under it.” The value of this reserve is analyzed quarterly and is adjusted accordingly. This adjustment (if any) to the reserve produces an expense or contra-expense in the consolidated statements of operations. Derivative Embedded Conversion Features The Company has recorded a derivative embedded conversion feature of the Series B Preferred Stock which is adjusted to its fair value as determined using Level 3 inputs described below under fair value measurement. The change in fair value of the derivative embedded conversion feature is calculated at each reporting date and recorded as other income or other expense on the statement of operations. Other liabilities At December 31, 2016, the total balance of $14.1 million of other liabilities is comprised of $12.3 million of accrued fees relating to the Series B Preferred Stock Financing, an accrual for professional fees and recurring business expenses currently payable of approximately $1.1 million and $0.7 million of accrued dividends relating to the Series B Preferred Stock. Comprehensive Income (Loss) The Company has no comprehensive income (loss) other than the net income (loss) disclosed in the consolidated statements of operations. Net Income (Loss) Per Common Share In calculating earnings per share, the Company follows the two-class method, which distinguishes between the classes of securities based on the proportionate participation rights of each security type in the Company's undistributed income. The Series A Preferred Stock and the Series B Preferred Stock are treated as one class for purposes of applying the two-class method, because they have substantially equal rights and share equally on an as converted basis with respect to income available to WMIH common stockholders. Basic net income (loss) per common share is computed by dividing net income (loss) applicable to WMIH’s common stockholders by the weighted-average number of common shares outstanding for the period after subtracting the weighted-average of any unvested restricted shares outstanding, as these are subject to repurchase. Basic net income (loss) attributable to common stockholders is computed by deducting preferred dividends and the basic calculation of undistributed earnings attributable to participating securities from net income. Diluted net income per common share is computed by dividing net income applicable to WMIH’s common stockholders by the weighted-average number of common shares outstanding during the period after subtracting the weighted-average of any unvested restricted shares outstanding, as these are subject to repurchase and adding any potentially dilutive WMIH common stock equivalents outstanding during the period. Diluted net income attributable to common stockholders is computed by deducting preferred dividends and the diluted calculation of undistributed earnings attributable to participating securities from net income. If common share equivalents exist, in periods where there is a net loss, diluted loss per common share would be equal to or less than basic net loss per common share, since the effect of including any common share equivalents would be antidilutive. Equity-Based Compensation On May 22, 2012, WMIH’s Board of Directors (the “Board” or “Board of Directors”) approved the Company’s 2012 Long-Term Incentive Plan (the “2012 Plan”) so that awards of restricted stock could be made to its non-employee directors and to have a plan in place for awards of equity based compensation to executives and others in connection with the Company’s operations and future strategic plans. A total of 2.0 million shares of WMIH’s common stock were initially reserved for future issuance under the 2012 Plan, which became effective upon the Board approval on May 22, 2012. On February 10, 2014, the Board approved and adopted a First Amendment to the 2012 Plan, pursuant to which the number of shares of WMIH’s common stock reserved and available for grants under the 2012 Plan was increased from 2.0 million shares to 3.0 million shares, and the terms of the 2012 Plan were modified to permit such an increase through action of the Board, except when stockholder approval is necessary to comply with any applicable law, regulation or rule of any stock exchange on which WMIH’s shares are listed, quoted or traded. On February 25, 2015, the number of shares authorized and available for awards under the 2012 Plan was increased from 3.0 million to 12.0 million shares of WMIH’s common stock, subject to approval of stockholders of WMIH. This approval was received at the Company’s Annual Meeting of Stockholders on April 28, 2015. The 2012 Plan provides for the granting of restricted shares and other cash and share based awards. The value of restricted stock is generally determined using the fair market value determined to be the trading price at the close of business on the respective date the awards were granted. Income Taxes The Company follows the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future income tax consequences attributable to differences between the carrying amounts and tax bases of assets and liabilities and losses carried forward and tax credits. Deferred tax assets and liabilities are measured using enacted tax rates and laws applicable to the years in which the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided to the extent that it is more likely than not that deferred tax assets will not be realized. The Company recognizes the financial statement effects of a tax position when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. Penalties and interest, of which there are none, would be reflected in income tax expense. Tax years are open to the extent the Company has net operating loss (“NOL”) carry-forwards available to be utilized currently. Dividend Policy WMIH has paid no dividends on its common stock on or after the Effective Date and currently has no plans to pay a dividend on its common stock. WMIH has declared and paid $18.0 million and $17.0 million of dividends on its Series B Preferred Stock during the years ended December 31, 2016 and December 31, 2015, respectively. An additional $0.7 million of dividends were accrued as of December 31, 2016 and December 31, 2015, respectively, based on the Series B Preferred Stock dividends that accrue at a rate of 3% per year. The Series B Preferred Stock was issued on January 5, 2015; therefore, no dividends were due or paid for any prior period. New Accounting Pronouncements In November 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-18—Statement of Cash Flows (Topic 230): Restricted Cash. This update contains amendments that are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. Stakeholders indicated that diversity exists in the classification and presentation of changes in restricted cash on the statement of cash flows under Topic 230, Statement of Cash Flows. Entities classify transfers between cash and restricted cash as operating, investing, or financing activities, or as a combination of those activities, in the statement of cash flows. Also, some entities present direct cash receipts into, and direct cash payments made from, a bank account that holds restricted cash as cash inflows and cash outflows, while others disclose those cash flows as noncash investing or financing activities. This Update addresses that diversity. The Company has reviewed this standard and determined that it is not expected to have a material impact on the Company’s consolidated financial position, results of operations or disclosure requirements, except as they relate to restricted cash in the statement of cash flows.

Insurance [Abstract]
Insurance Activity	Note 3: Insurance Activity The Company, through WMMRC, reinsures mortgage guaranty risks of mortgage loans originated by affiliates of the Company during the period from 1997 through 2008. WMMRC is (or was) a party to reinsurance agreements with UGRIC, GMIC, MGIC, PMI, Radian, RMIC and Triad. The agreements with UGRIC and Triad were placed into runoff effective May 31, 2008. The agreements with all other primary mortgage insurers were placed into runoff effective September 26, 2008. The reinsurance agreements with Triad, PMI and UGRIC were commuted on August 31, 2009, October 2, 2012 and April 3, 2014, respectively. All agreements between WMMRC and the primary mortgage insurers are on an excess of loss basis, except for certain reinsurance treaties with GMIC and Radian during 2007 and 2008, which are reinsured on a 50% quota share basis. Pursuant to the excess of loss reinsurance agreements, WMMRC reinsures a second loss layer which ranges from 5% to 10% of the risk in force in excess of the primary mortgage insurer’s first loss percentages which range from 4% to 5%. Each calendar year, or book year, is treated separately from other years when calculating losses. In return for accepting a portion of the risk, WMMRC receives, net of ceding commission, a percentage of the premium that ranges from 25% to 40%. As security for the ceding insurers, WMMRC has entered into separate trust agreements with each of the primary mortgage insurance companies whereby a portion of the funds from premiums assumed are held in trust accounts for the benefit of each separate insurer. Pursuant to the terms of the reinsurance agreements, WMMRC is required to keep such assets in trust for a minimum of five years and is subject to claims for up to ten years from termination of obligations arising from the last year in which insurance business was written prior to runoff. Release of funds from the trust by WMMRC requires approval from the primary mortgage guaranty companies. Premiums assumed and earned are as follows for the periods ended December 31, 2016, 2015 and 2014, respectively: Year ended December 31, 2016 Year ended December 31, 2015 Year ended December 31, 2014 Premiums assumed $ 2,656 $ 4,788 $ 6,869 Change in unearned premiums 491 333 300 Premiums earned $ 3,147 $ 5,121 $ 7,169 The components of the liability for losses and loss adjustment reserves are as follows as of December 31, 2016 and 2015, respectively: December 31, 2016 December 31, 2015 Case-basis reserves $ 553 $ 4,193 IBNR reserves — 75 Premium deficiency reserves 258 795 Total losses and loss adjustment reserves $ 811 $ 5,063 Losses and loss adjustment reserve activity are as follows for the years ended December 31, 2016 and 2015, respectively: Year ended December 31, 2016 Year ended December 31, 2015 Balance at beginning of period $ 5,063 $ 18,947 Released - prior periods (669 ) (1,115 ) Paid or terminated - prior periods (3,583 ) (12,769 ) Total losses and loss adjustment reserves $ 811 $ 5,063 The loss contract reserve balance is analyzed and adjusted quarterly. The balances in the reserve were $5.6 million and $9.6 million at December 31, 2016 and December 31, 2015, respectively. The loss contract reserve was established on March 19, 2012 at $63.1 million. The reserve was decreased by $4.0 million, $2.9 million and $33.8 million during the periods ended December 31, 2016, 2015 and 2014, respectively, resulting from the planned runoff of the underlying policies and the commutation of the UGRIC reinsurance agreement in 2014, resulting in corresponding decreases in expense of the respective amount for each period.

Income Taxes	Note 5: Income Taxes For the year ended December 31, 2016, the Company recorded net income of approximately $201.7 million. For the year ended December 31, 2015, we recorded a net loss of approximately $61.8 million, and for the year ended December 31, 2014, we recorded net income of approximately $3.1 million. The Company has not recorded an income tax expense or benefit for the years ended December 31, 2016, 2015 or 2014. 2016 2015 2014 Current federal income tax expense $ — $ — $ — Provision for doubtful federal income tax receivable — — — Deferred federal income tax (benefit) expense — — — Federal income tax benefit $ — $ — $ — The items accounting for the difference between income taxes computed at the U.S. federal statutory rate and our effective rate were as follows: Year Ended Year Ended Year Ended December 31, 2016 December 31, 2015 December 31, 2014 Income tax at the federal statutory rate of 35% 35.0 % 35.0 % 35.0 % Effect of: Dividends on preferred securities 3.4 (8.0) — True-up of deferred assets (0.5 ) Adjustments to NOL due to 382 limitation — — (9.0) Change in valuation allowance (37.9) (27.0) (26.0) Effective rate —% —% —% The Company files a consolidated federal income tax return. Pursuant to a tax sharing agreement, WMMRC’s federal income tax liability is calculated on a separate return basis determined by applying 35% to taxable income, in accordance with the provisions of the United States Internal Revenue Code of 1986, as amended (the “Code”), that apply to property and casualty insurance companies. WMIH, as WMMRC’s parent, pays federal income taxes on behalf of WMMRC and settles the federal income tax obligation on a current basis in accordance with the tax sharing agreement. WMMRC made no tax payments to WMIH during the years ended December 31, 2016, 2015 or 2014 associated with the Company’s tax liability from the preceding year. Deferred federal income taxes arise from temporary differences between the valuation of assets and liabilities as determined for financial reporting purposes and income tax purposes. Temporary differences principally relate to discounting of loss reserves, accruals, derivate liabilities, net operating losses, and unrealized gains and losses on investments. As of December 31, 2016, 2015 and 2014, the Company recorded a valuation allowance equal to 100% of the net deferred federal income tax asset due to uncertainty regarding the Company’s ability to realize these benefits in the future. The components of the net deferred tax asset as of December 31, 2016, 2015 and 2014, respectively, are as follows: Year Ended Year Ended Year Ended December 31, 2016 December 31, 2015 December 31, 2014 Deferred federal income tax asset: Net operating loss carryforward $ 2,104,944 $ 2,102,482 $ 2,098,597 Accruals and reserves 2,177 3,481 4,531 Derivative liability — 19,117 — Restricted stock grants 157 160 — As filed adjustments — — 214 Net unrealized loss on investments 23 16 — Capital loss carryforward 52,475 52,490 52,603 Total deferred federal income tax asset 2,159,776 2,177,746 2,155,945 Deferred federal income tax liabilities: Net unrealized gain on investments — — 154 Losses and loss adjustments expense 500 411 102 Derivative asset 51,407 — — Total deferred federal income tax liabilities 51,907 411 256 Less: Valuation allowance 2,107,869 2,177,335 2,155,689 Net deferred federal income tax asset $ — $ — $ — On March 19, 2012, WMIH emerged from bankruptcy. Prior to emergence, WMI abandoned the stock of WMB, thereby generating a worthless stock deduction of approximately $8.37 billion which gives rise to an NOL for the year ended December 31, 2012. Under Section 382 of the Code (“Section 382”), and based on the Company’s analysis, we believe that the Company experienced an “ownership change” (generally defined as a greater than 50% change (by value) in our equity ownership over a three-year period) on March 19, 2012, and our ability to use our pre-change of control NOLs and other pre-change tax attributes against our post-change income was limited. The Section 382 limitation is applied annually so as to limit the use of our pre-change NOLs to an amount that generally equals the value of our stock immediately before the ownership change multiplied by a designated federal long-term tax-exempt rate. Due to applicable limitations under Section 382 and a reduction of tax attributes due to cancellation of indebtedness, a portion of these NOLs were limited and will expire unused. We believe that the total available and utilizable NOL carry forward at December 31, 2016 is approximately $6.0 billion. At December 31, 2016, there was no limitation on the use of these NOLs. These NOLs will begin to expire in 2031. The Company’s ability to utilize the NOLs or realize any benefits related to the NOLs is subject to a number of risks. The Company accounts for uncertain tax positions in accordance with the income tax accounting guidance. The Company has analyzed filing positions in the federal and state jurisdiction where it is required to file tax returns, as well as the open tax years in these jurisdictions. Tax years 2011 to present are subject to examination by the Internal Revenue Service. The Company believes that its federal income tax filing positions and deductions will be sustained on audit and does not anticipate any adjustments that will result in a material change to its financial position. Therefore, no reserves for uncertain federal income tax positions have been recorded. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of the provision for federal income taxes. The Company did not incur any federal income tax related interest income, interest expense or penalties for the years ended December 31, 2016, December 31, 2015 and December 31, 2014.

Related Party Transactions [Abstract]
Service Agreements and Related Party Transactions	Note 6: Service Agreements and Related Party Transactions WMMRC has engaged a Hawaii-based service provider, Marsh Management Services, Inc., to provide accounting and related management services for its operations. In exchange for performing these services, WMMRC pays such service provider a management fee. WMIH entered into an Investment Management Agreement and an Administrative Services Agreement with WMMRC on March 19, 2012. Each of these agreements was approved by WMMRC’s primary regulator, the Insurance Division of the State of Hawaii. Total amounts incurred under these agreements totaled $1.4 million, $1.4 million and $1.5 million for the years ended December 31, 2016, December 31, 2015 and December 31, 2014, respectively. The expense and related income eliminate on consolidation. These agreements are described below. Under the terms of such Investment Management Agreement, WMIH receives from WMMRC a fee equal to the product of (x) the ending dollar amount of assets under management during the calendar month in question and (y) .002 divided by 12. WMIH is responsible for investing the funds of WMMRC based on applicable investment criteria and subject to rules and regulations to which WMMRC is subject. Under the terms of such Administrative Services Agreement, WMIH receives from WMMRC a fee of $110 thousand per month. WMIH is responsible for providing administrative services to support, among other things, supervision, governance, financial administration and reporting, risk management, and claims management as may be necessary, together with such other general or specific administrative services that may be reasonably required or requested by WMMRC in the ordinary course of its business. On March 22, 2012, WMIH and the WMI Liquidating Trust (the “Trust”) entered into a Transition Services Agreement (the “TSA”). Pursuant to the TSA, the Trust makes available certain services and employees. The TSA provides the Company with basic infrastructure and support services to facilitate the Company’s operations. The TSA, as amended, extends the term of the agreement through April 30, 2017, with automatic renewals thereafter for successive additional three-month terms, subject to non-renewal at the end of any additional term upon written notice by either party at least 30 days prior to the expiration of the additional term. In connection with implementing the Plan, certain holders of specified “Allowed Claims” had the right to elect to receive such holder’s “Pro Rata Share of the Common Stock Allotment.” Essentially, the Plan defines the “Pro Rata Share of the Common Stock Allotment” as a pro rata share of ten million (10,000,000) shares of WMIH’s common stock (i.e., five percent (5%)) issued and outstanding on the Effective Date. Holders exercising the foregoing election did so in lieu of receiving (i) 50% of such holder’s interest in and to certain litigation proceeds that could be realized by the Trust on account of certain claims and causes of action asserted by the Trust as contemplated by the Plan (“Litigation Proceeds”), and (ii) some or all of the Runoff Notes to which such holder may be entitled (if such holder elected to receive Runoff Notes in accordance with the terms of the Plan). If a holder exercised the election described above and, as a result of such election, received shares of WMIH’s common stock, then such holder’s share of Runoff Notes to which the election was effective (i.e., One Dollar ($1.00) of original principal amount of Runoff Notes for each share of WMIH’s common stock) were not issued. In addition, as a result of making the aforementioned election, such holders conveyed to WMIH, and WMIH retained, an economic interest in Litigation Proceeds, if any, recovered by the Trust in connection with certain litigation brought by the Trust as contemplated by the Plan. Distributions, if any, to WMIH on account of the foregoing will be effected in accordance with the Plan and the court order confirming the Plan. On or about October 14, 2014, the Trust filed a lawsuit in King County Superior Court in the State of Washington against 16 former directors and officers of WMI (the “D&O Litigation”). The Trust’s complaint alleged, among other things, that the defendants named therein breached their fiduciary duties to WMI and committed corporate waste and fraud by squandering WMI’s financial resources. In connection with the settlement of the D&O Litigation, during the year ended December 31, 2015, among the Trust, certain former directors and officers of WMI and certain insurance carriers that underwrote director and officer liability insurance policies for the benefit of WMI and its affiliates (including such former directors and officers), such insurance carriers agreed to pay the Trust $37.0 million, of which $3.0 million would be placed into a segregated reserve account (the “RSA Reserve”) to be administered by a third party pursuant to the terms of a Reserve Settlement Agreement (the “RSA”). During the years ended December 31, 2016 and 2015, respectively, WMIH had other income of $123 thousand and $7.8 million as a result of its receipt of its share of net Litigation Proceeds related to the D&O Litigation. As of December 31, 2016, $2.0 million remained in the RSA Reserve. Under the RSA, funds are released from the RSA Reserve to the Trust if and when certain designated conditions are satisfied. If and when these funds are released to the Trust, and to the extent WMIH is entitled to receive such funds in accordance with the Plan, it is anticipated the Trust will make payments to WMIH in an amount equal to WMIH’s share of Litigation Proceeds as provided under the Plan. Due to the contingent nature of future distributions from the RSA Reserve, there can be no assurance that WMIH will receive any distributions from the remaining balance in the RSA Reserve in the future. As of December 31, 2016, WMIH had not received any Litigation Proceeds, other than as described above. In preparation for the offering of the Series B Preferred Stock, WMIH engaged KKR Capital Markets LLC (“KCM”), an affiliate of KKR & Co. L.P., to act as a joint book-running manager for the Series B Preferred Stock offering. KCM also acted as an initial purchaser of the Series B Preferred Stock. During the year ended December 31, 2015, as a result of satisfying a post-closing covenant to reincorporate in the State of Delaware within 180 days following the closing of the Series B Preferred Stock offering, we paid $8.25 million to KCM. Upon consummation of a “Qualified Acquisition” (as such term is defined in Article VI of WMIH’s Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”)), we will pay KCM an additional fee (the “KCM Deferred Fee”) of $8.25 million. We have recorded the KCM Deferred Fee in “other liabilities” on our consolidated balance sheet and this amount is included in “accrued fees relating to Series B Preferred Stock issuance” on our consolidated statements of cash flows.

Notes Payable	Note 7: Notes Payable On the Effective Date, WMIH issued $110.0 million aggregate principal amount of its 13% Senior First Lien Notes due 2030 (the “First Lien Notes”) under an indenture, dated as of March 19, 2012, (the “First Lien Indenture”), between WMIH and Wilmington Trust, National Association, as Trustee. Additionally, WMIH issued $20.0 million aggregate principal amount of its 13% Senior Second Lien Notes due 2030 (the “Second Lien Notes” and, together with the First Lien Notes, the “Runoff Notes”) under an indenture, dated as of March 19, 2012, (the “Second Lien Indenture” and, together with the First Lien Indenture, the “Indentures”), between WMIH and The Law Debenture Trust Company of New York, as Trustee. On January 5, 2017, The Law Debenture Trust Company of New York notified WMIH that it had completed the transfer of substantially all of its corporate trust business to Delaware Trust Company, and that Delaware Trust Company had become the successor trustee under the Second Lien Indenture. The Runoff Notes are scheduled to mature on March 19, 2030 and pay interest quarterly. The Runoff Notes are secured by, and have a specified priority in right of payment in, a securities or deposit account into which WMIH is required to deposit distributions it receives of Runoff Proceeds (as defined in the Indentures) (the “Collateral Account”).

As of the Effective Date, and pursuant to WMIHC’s Amended and Restated Articles of Incorporation (the “Articles”), WMIHC was authorized to issue up to 500,000,000 shares of common stock and up to 5,000,000 shares of blank check preferred stock, in one or more series, each with a par value of $0.00001 per share. 200,000,000 shares of common stock were issued by WMIH pursuant to the Plan and in reliance on Section 1145 of the United States Bankruptcy Code on the Effective Date. On the Reincorporation Date, all shares of common and preferred equity securities previously issued by WMIHC automatically were converted into one share of the substantially similar common stock, Series A Preferred Stock or Series B Preferred Stock, as applicable, of WMIH. At the same time, each outstanding option, right or warrant to acquire shares of WMIHC’s common stock was converted into an option, right or warrant to acquire an equal number of shares of WMIH’s common stock under the same terms and conditions as the original options, rights or warrants. As of the Reincorporation Date, and pursuant to WMIH’s Certificate of Incorporation, WMIH is authorized to issue up to 3,500,000,000 shares of common stock and up to 10,000,000 shares of preferred stock, in one or more series, each with a par value of $0.00001 per share.

The Series A Preferred Stock has rights substantially similar to those associated with WMIH’s common stock, with the exception of a liquidation preference, conversion rights and customary anti-dilution protections. The Series A Preferred Stock has a liquidation preference equal to the greater of (i) $10.00 per one million shares of Series A Preferred Stock plus declared but unpaid dividends on such shares and (ii) the amount that the holder would be entitled to in a relevant transaction had the Series A Preferred Stock been converted to common stock of WMIH. The Series A Preferred Stock is convertible at a conversion price of $1.10 per share into shares of common stock of WMIH either at the option of the holder or automatically upon transfer by KKR Fund to a non-affiliated party. As a result of the calculation of a beneficial conversion feature as required by accounting standards codification topic 470, Debt a preferred deemed dividend of $9.5 million was recorded in conjunction with the issuance of the Series A Preferred Stock. This preferred deemed dividend resulted in an increase to our accumulated deficit, and an increase in additional paid in capital. Further, KKR Fund, as the holder of the Series A Preferred Stock and the Warrants, has received other rights pursuant to the Investor Rights Agreement as described below. The Warrants have a five-year term from the date of issuance and are subject to customary structural adjustment provisions for stock splits, combinations, recapitalizations and other similar transactions.

Pursuant to the Investor Rights Agreement, for so long as the Series A Holders own 50% of the Series A Preferred Stock issued as of January 30, 2014 (or the underlying common stock of WMIH), the Series A Holders will have the right to appoint two of the nine directors that currently comprise the Board. In accordance with the Investor Rights Agreement, except for the issuance of WMIH’s common stock in respect of the Warrants and the Series A Preferred Stock, KKR Fund and its affiliates shall not purchase or acquire any equity securities of WMIH or its subsidiaries without WMIH’s prior written consent, subject to certain exceptions. The Investor Rights Agreement also provides the Series A Holders with registration rights, including three long form demand registration rights, unlimited short form demand registration rights and customary piggyback registration rights with respect to WMIH’s common stock (and WMIH’s common stock underlying the Series A Preferred Stock and the Warrants), subject to certain minimum thresholds, customary blackout periods and lockups of 180 days.

The R The foregoing description of the Registration Rights Agreement is qualified in its entirety by the provisions of the Registration Rights Agreement, filed on Form 8-K on January 5, 2015, as Exhibit 10.1 and incorporated by reference herein. On January 5, 2015, in connection with the offering and pursuant to the Purchase Agreement, WMIH entered into an Escrow Agreement (the “Escrow Agreement”) with Citibank, N.A., as Escrow Agent (the “Escrow Agent”), pursuant to which WMIH caused to be deposited with the Escrow Agent the amount of $598.5 million, representing the proceeds of the offering of Series B Preferred Stock less offering fees payable on the Issue Date but before payment of other offering fees and expenses (including fees contingent upon future events). These net proceeds will be released from escrow from time to time to WMIH as instructed by WMIH in amounts necessary to (i) pay certain fees related to the offering that may become payable to the Initial Purchasers, (ii) finance WMIH’s efforts to explore and/or fund, in whole or in part, acquisitions, whether completed or not, including reasonable attorney fees and expenses related thereto, accounting expenses, due diligence and financial advisor fees and expenses, (iii) pay certain amounts that may become payable to the holders of the Series B Preferred Stock upon the occurrence of certain put events, (iv) pay certain amounts that would become payable to the holders of the Series B Preferred Stock upon a mandatory redemption of the Series B Preferred Stock, and (v) pay certain expenses related to the offering.

If a Qualified Acquisition is not consummated by January 5, 2018, and no Acquisitions (as defined in Article VI of the Certificate of Incorporation) have been consummated such that all of the Series B Preferred Stock remains outstanding and has not been converted to WMIH’s common stock, the outstanding Series B Preferred Stock becomes redeemable. The aggregate redemption costs, assuming all 600,000 shares remain outstanding, of all of the Series B Preferred Stock is $600.0 million, plus accrued and unpaid dividends, if any, whether or not declared. As of December 31, 2016 and December 31, 2015, the balance remaining in the escrow account totaled approximately $572.9 million and $571.4 million, respectively.

A derivative liability results primarily when the Company average stock price (as defined in the Certificate of Incorporation) exceeds the conversion price, including the ceiling conversion price of $2.25, as defined by the Certificate of Incorporation. A derivative asset results when the Company’s average stock price is less than the conversion price, including the floor price of $1.75. constitute other income or expense, as the case may be, in the applicable reporting period.

Earnings Per Share [Abstract]
Net (Loss) Income Per Common Share	Note 12: Net (Loss) Income Per Common Share In calculating earnings per share, the Company follows the two-class method, which distinguishes between the classes of securities based on the proportionate participation rights of each security type in the Company's undistributed income. The Series A Preferred Stock and the Series B Preferred Stock are treated as one class for purposes of applying the two-class method, because they have substantially equal rights and share equally on an as converted basis with respect to income available to WMIH common stockholders. Basic net income per WMIH share attributable to common and participating stockholders is computed by dividing net income attributable to WMIH’s common stockholders by the weighted-average number of common shares outstanding for the period after subtracting the weighted-average of any unvested restricted shares outstanding, as these shares are subject to repurchase. Basic net income attributable to common stockholders is computed by deducting preferred dividends and the basic calculation of undistributed earnings attributable to participating securities from net income. Diluted net income per WMIH share would be computed by dividing net income attributable to WMIH’s common stockholders for the period by the weighted-average number of common shares outstanding after subtracting the weighted-average of any incremental unvested restricted shares outstanding and adding any potentially dilutive common equivalent shares outstanding during the period, if dilutive. Potentially dilutive common equivalent shares are composed of the incremental common shares issuable upon the exercise of warrants for WMIH’s common stock and the potential conversion of preferred shares to common shares and the dilutive effect of unvested restricted stock. Diluted net income attributable to common stockholders is computed by deducting preferred dividends and the diluted calculation of undistributed earnings attributable to participating securities from net income. The dilutive effect of outstanding warrants and restricted stock subject to repurchase is reflected in diluted earnings per share by application of the treasury stock method. There would be no dilutive effects from any equity instruments for periods presented reflecting a net loss, therefore diluted net loss per share would be the same as basic net loss for periods that reflect a net loss attributable to common stockholders. Certain unvested restricted shares and convertible preferred stock are excluded from the calculation of diluted earnings per share until the non-market based contingency occurs. The following table presents the calculation of basic net income (loss) per share attributable to common stockholders for the periods presented: (in thousands, except share and per share data) Year ended December 31, 2016 Year ended December 31, 2015 Year ended December 31, 2014 Numerator for basic net income (loss) per share: Net income (loss) $ 201,700 $ (61,833 ) $ 3,070 Less: Series B preferred stock dividends (18,000 ) (17,748 ) — Less: Preferred deemed dividend — — (9,455 ) Less: undistributed earnings attributed to participating securities (basic calculation) (116,774 ) — — Basic net income (loss) attributable to common stockholders $ 66,926 $ (79,581 ) $ (6,385 ) Denominator for basic net income (loss) per share: Weighted-average shares outstanding 206,291,857 204,776,405 202,208,619 Weighted-average unvested restricted shares outstanding (4,020,970 ) (3,029,792 ) (1,338,691 ) Denominator for basic net income (loss) per share 202,270,887 201,746,613 200,869,928 Basic net income (loss) per share attributable to common stockholders $ 0.33 $ (0.39 ) $ (0.03 ) The following table presents the calculation of diluted net income (loss) per share attributable to common stockholders for the periods presented: (in thousands, except share and per share data) Year ended December 31, 2016 Year ended December 31, 2015 Year ended December 31, 2014 Numerator for basic net income (loss) per share: Net income (loss) $ 201,700 $ (61,833 ) $ 3,070 Less: Series B preferred stock dividends (18,000 ) (17,748 ) — Less: Preferred deemed dividend — — (9,455 ) Less: Net income attributed to participating securities (112,115 ) — — Diluted net income (loss) attributable to common stockholders $ 71,585 $ (79,581 ) $ (6,385 ) Denominator for diluted net income (loss) per share: Weighted-average shares outstanding 206,291,857 204,776,405 202,208,619 Weighted-average unvested restricted shares outstanding (4,020,970 ) (3,029,792 ) (1,338,691 ) Effect of dilutive potential shares * 33,135,473 — — Denominator for diluted net income (loss) per share: 235,406,360 201,746,613 200,869,928 Diluted net income (loss) per share attributable to common shareholders $ 0.30 $ (0.39 ) $ (0.03 ) *There were no dilutive effects from any equity instruments for periods presented which did not have net income, therefore diluted net (loss) income per share was the same as basic net (loss) income for periods presented which reflect a net loss.

Fair Value Measurement

Fair Value Measurement	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurement	Note 13: Fair Value Measurement We use a fair-value approach to value certain liabilities. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. We use a fair value hierarchy, which distinguishes between assumptions based on market data (observable inputs) and an entity’s own assumptions (unobservable inputs). The hierarchy consists of three levels: • Level 1 — Inputs to the valuation methodology are quoted prices for identical assets or liabilities traded in active markets; • Level 2 — Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and market corroborated inputs; and • Level 3 — Valuations based on models where significant inputs are not observable. The unobservable inputs reflect the Company’s own assumptions about the inputs that market participants would use. Determining which category an asset or liability falls within the fair value accounting guidance hierarchy requires significant judgment. We evaluate our hierarchy disclosures each quarter. Assets and liabilities measured at fair value on a recurring basis are summarized as follows: The financial instrument that is measured at fair value on a recurring basis is summarized as follows as of December 31, 2016: Assets Level 1 Level 2 Level 3 December 31, 2016 Derivative embedded conversion feature $ — $ — $ 80,651 $ 80,651 The financial instrument that is measured at fair value on a recurring basis is summarized as follows as of December 31, 2015: Liabilities Level 1 Level 2 Level 3 December 31, 2015 Derivative embedded conversion feature $ — $ — $ 120,848 $ 120,848 At December 31, 2014, we had no Level 3 assets or liabilities measured at fair value. The following table shows the change in Level 3 financial instrument measured at fair value on a recurring basis for the period ended December 31, 2016: Derivative asset (liability) embedded conversion feature Balance, December 31, 2014 $ — Issuance during 2015 (66,227 ) Unrealized (loss) on change in fair value (54,621 ) Balance, December 31, 2015 (120,848 ) Issuance during 2016 — Unrealized gain on change in fair value 201,499 Balance, December 31, 2016 $ 80,651 On January 5, 2015, WMIH raised $600.0 million of capital (less transaction costs) through the issuance of 600,000 shares of Series B Preferred Stock. The shares carry a liquidation preference of $1,000 per share, equal to their initial purchase price. In addition, they have a mandatory redemption right three years from the issuance date at a price equal to the initial investment amount, and accrue dividends at 3% per annum. The purpose of the capital raise was principally to pursue strategic acquisitions of operating companies that fit the Company’s desired business model. Management intends to pursue such an acquisition or acquisitions with the proceeds of the capital raise, and should it occur during the three-year term of the Series B Preferred Stock, there is a mandatory conversion of these shares into common stock of WMIH. Mandatory conversion occurs at a price that is the lesser of: i) $2.25 per share of WMIH’s common stock; and ii) the arithmetic average of daily volume weighted-average prices of WMIH’s common stock during the 20 trading day period ending on the trading day immediately preceding the public announcement by WMIH of its entry into a definitive agreement for such acquisition, subject to a floor of $1.75 per share of WMIH’s common stock. We use a binomial lattice option pricing model to value the embedded conversion feature that is subject to fair value liability accounting. The key inputs which we utilize in the Our reported net income attributable to common and participating stockholders (“Net Income”) was approximately $183.7 million for the twelve months ended December 31, 2016. If the closing stock price of WMIH’s common stock had been 10% lower, our Net Income would have been approximately $23.2 million higher. If the closing stock price of WMIH’s common stock had been 10% higher, our Net Income would have been approximately $30.4 million lower. If our volatility assumption on December 31, 2016 had been 10% lower, our Net Income would have been approximately $5.4 million lower and if our volatility assumption had been 10% higher, our Net Income would have been approximately $0.9 million lower. If our probability of a transaction occurring assumption on December 31, 2016 had been 10% lower, our Net Income would have been approximately $9.0 million lower and if our probability of a transaction occurring assumption had been 10% higher, our Net Income would have been approximately $9.0 million higher.

Significant Accounting Polici22

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Basis of Presentation	Basis of Presentation WMIH resumed timely filing of all periodic reports for a reporting company under the Securities Exchange Act of 1934, as amended, for all periods after emergence from bankruptcy on March 19, 2012 (the “Effective Date”). All significant intercompany transactions and balances have been eliminated in preparing the consolidated financial statements.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with Generally Accepted Accounting Principles in the United States (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Management has made significant estimates in certain areas, including valuing certain financial instruments, other assets and liabilities, the determination of the contingent risk liabilities, and in determining appropriate insurance reserves. Actual results could differ substantially from those estimates.
Fair Value of Certain Financial Instruments	Fair Value of Certain Financial Instruments Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Generally, for assets that are reported at fair value, the Company uses quoted market prices or valuation models to estimate their fair value. These models incorporate inputs such as forward yield curves, market volatilities and pricing spreads, utilizing market-based inputs where readily available. The degree of management judgment involved in estimating the fair value of a financial instrument or other asset is dependent upon the availability of quoted market prices or observable market inputs. For financial instruments that are actively traded in the marketplace or whose values are based on readily available market value data, little judgment is necessary when estimating the instrument’s fair value. When observable market prices and data are not readily available, significant management judgment often is necessary to estimate fair value. In those cases, different assumptions could result in significant changes in valuation. The Company classifies fixed-maturity investments as trading securities, which are recorded at fair value. As such, changes in unrealized gains and losses on investments held at the balance sheet date are recognized and reported as a component of net investment income on the consolidated statements of operations. The Company believes fair value provides better matching of investment earnings to potential cash flow generated from the investment portfolio and reduces subjectivity related to evaluating other-than-temporary impairment on the Company’s investment portfolio. The carrying value of cash and cash equivalents, restricted cash, accounts payable and accrued liabilities approximate their respective fair values due to their short-term nature. The carrying value of the loss contract reserve approximates its fair value and is based on valuation methodologies using discounted cash flows at interest rates which approximate the Company’s weighted-average cost of capital. The carrying value of the derivative embedded conversion feature of the Series B Preferred Stock is adjusted to its fair value as determined using Level 3 inputs described below under fair value measurement. The carrying value of notes payable approximates fair value based on time to maturity, underlying collateral, and prevailing interest rates.
Fair Value Measurement	Fair Value Measurement The Company’s estimates of fair value for financial assets and financial liabilities are based on the framework established in the Financial Accounting Standards Board Fair Value Measurements and Disclosures accounting guidance. The framework is based on the inputs used in valuation and requires that observable inputs be used in the valuations when available. The disclosure of fair value estimates in the fair value accounting guidance hierarchy is based on whether the significant inputs into the valuation are observable. In determining the level of the hierarchy in which the estimate is disclosed, the highest priority is given to unadjusted quoted prices in active markets and the lowest priority to unobservable inputs that reflect the Company’s significant market assumptions. The three levels of the hierarchy are as follows: Level 1—Inputs to the valuation methodology are quoted prices for identical assets or liabilities traded in active markets. Level 2—Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and market corroborated inputs. Level 3—Valuations based on models where significant inputs are not observable. The unobservable inputs reflect the Company’s own assumptions about the inputs that market participants would use. Fair values are based on quoted market prices when available (Level 1). The Company receives the quoted market prices from a third party, nationally recognized pricing service. When quoted prices are not available, the Company utilizes a pricing service to determine an estimate of fair value. The fair value is generally estimated using current market inputs for similar financial instruments with comparable terms and credit quality, commonly referred to as matrix pricing (Level 2). These valuation techniques involve some level of management estimation and judgment. The Company recognizes transfers between levels in the fair value hierarchy at the end of the reporting period.
Investments Held in Trust	Investments Held in Trust Investments held in trust consist of cash equivalents, which include highly liquid overnight money market instruments, and fixed-maturity securities which are held in trust for the benefit of the primary insurers as more fully described in Note 3: Insurance Activity and Note 4: Investment Securities, and are subject to the restrictions on distribution of net assets of subsidiaries as described below.
Third Party Restrictions on Distribution of Net Assets of Wholly-Owned Subsidiaries	Third Party Restrictions on Distribution of Net Assets of Wholly-Owned Subsidiaries The net assets of WMMRC are subject to restrictions on distribution from multiple sources including the primary insurers who have approval control of distributions from the trust, the Insurance Division of the State of Hawaii who has approval authority over distributions or intercompany advances, and additional restrictions as described in Note 7: Notes Payable.
Premium Recognition	Premium Recognition Premiums assumed are earned on a daily pro-rata basis over the underlying policy terms. Premiums assumed relating to the unexpired portion of policies in force at the balance sheet date are recorded as unearned premiums. Unearned premiums also include a reserve for post default premium reserves. Post default premium reserves occur when a loan is in a default position and the servicer continues to advance the premiums. If the loan ultimately goes to claim, the premiums advanced during the period of default are subject to recapture. The Company records a post default premium reserve based on information provided by the underlying mortgage insurers when they provide information on the post default premium reserve separately from other reserves. The change in the post default premium reserve is reflected as a reduction or increase, as the case may be, in premiums assumed. The Company has recorded unearned premiums totaling $0.3 million and $0.8 million as of December 31, 2016 and December 31, 2015, respectively. The Company recognizes premium deficiencies when there is a probable loss on an insurance contract. Premium deficiencies are recognized if the sum of the present value of expected losses and loss adjustment expenses, unamortized deferred acquisition costs, and maintenance costs, excluding intercompany charges, exceed expected future unearned premiums and anticipated investment income. Premium deficiency reserves have been recorded totaling $0.3 million and $0.8 million as of December 31, 2016 and December 31, 2015, respectively. Due to the runoff nature of the WMMRC business, the intercompany maintenance costs were excluded from the computation of premium deficiencies during the current period and will also be excluded during future periods. The Company’s premium deficiency analysis was performed on a single book basis and includes all book years and reinsurance treaties aggregated together using assumptions based on the actuarial best estimates at the balance sheet date. The calculation for premium deficiency requires significant judgment and includes estimates of future expected premiums, claims, loss adjustment expenses and investment income as of the balance sheet date. To the extent ultimate losses are higher or premiums are lower than estimated, additional premium deficiency reserves may be required in the future.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash on hand, amounts due from banks, U.S. Treasury bills and overnight investments. Except as described above in Investments Held in Trust, the Company considers all amounts that are invested in highly liquid overnight money market instruments to be cash equivalents. The Federal Deposit Insurance Corporation (“FDIC”)
Restricted Cash	Restricted Cash Restricted cash includes (i) amounts held for the express purposes of paying principal, interest and related fees on the Runoff Notes (as defined in Note 7: Notes Payable) pursuant to the terms of the Indentures (as defined in Note 7: Notes Payable) and (ii) proceeds of the Series B Preferred Stock offering held in escrow.
Ceding Commission Expense	Ceding Commission Expense The Company is required to pay a ceding commission to certain primary insurers pursuant to certain reinsurance agreements.
Losses and Loss Adjustment Reserves	Losses and Loss Adjustment Reserves The losses and loss adjustment reserve includes case basis estimates of reported losses and supplemental amounts for incurred but not reported losses (“IBNR”). A default is considered the incident (e.g., the failure to make timely payment of mortgage payments) that may give rise to a claim for mortgage insurance. In establishing the losses and loss adjustment reserve, the Company based its estimates primarily on the ceded loss and loss adjustment reserves as provided by the primary mortgage guaranty carriers. WMMRC has recorded reserves at the ceded case reserves and IBNR levels established and reported by the primary mortgage guaranty carriers as of December 31, 2016 and December 31, 2015, respectively. Management believes that the recorded aggregate liability for unpaid losses and loss adjustment expenses at period end represents the Company’s best estimate, based upon the available data, of the amount necessary to cover the current cost of losses. However, due to the inherent uncertainty arising from fluctuations in the persistency rate of mortgage insurance claims, the Company’s size and lack of prior operating history, external factors such as future changes in regional or national economic conditions, judicial decisions, federal and state legislation related to mortgage restructuring and foreclosure restrictions, claims denials and coverage rescissions by primary carriers and other factors beyond the Company’s control, it is not presently possible to determine whether actual loss experience will conform to the assumptions used in determining the estimated amounts for such liability at the balance sheet date. Accordingly, the ultimate liability could be significantly higher or lower, as the case may be, than the amount indicated in the financial statements and there can be no assurance that the reserve amounts recorded will be sufficient. As adjustments to these estimates become necessary, such adjustments are reflected in current operations.
Loss Contract Reserves	Loss Contract Reserves A loss contract reserve relating to contractual obligations of WMMRC was established at March 19, 2012 as a result of applying fresh start accounting and in compliance with Accounting Standards Codification (“ASC”) 805-10-55-21 (b) (1) which defines a loss contract as a “contract in which the unavoidable costs of meeting the obligations under the contract exceed the economic benefits expected to be received under it.” The value of this reserve is analyzed quarterly and is adjusted accordingly. This adjustment (if any) to the reserve produces an expense or contra-expense in the consolidated statements of operations.
Derivative Embedded Conversion Features	Derivative Embedded Conversion Features The Company has recorded a derivative embedded conversion feature of the Series B Preferred Stock which is adjusted to its fair value as determined using Level 3 inputs described below under fair value measurement. The change in fair value of the derivative embedded conversion feature is calculated at each reporting date and recorded as other income or other expense on the statement of operations.
Other liabilities	Other liabilities At December 31, 2016, the total balance of $14.1 million of other liabilities is comprised of $12.3 million of accrued fees relating to the Series B Preferred Stock Financing, an accrual for professional fees and recurring business expenses currently payable of approximately $1.1 million and $0.7 million of accrued dividends relating to the Series B Preferred Stock.
Comprehensive Income (Loss)	Comprehensive Income (Loss) The Company has no comprehensive income (loss) other than the net income (loss) disclosed in the consolidated statements of operations.
Net Income (Loss) Per Common Share	Net Income (Loss) Per Common Share In calculating earnings per share, the Company follows the two-class method, which distinguishes between the classes of securities based on the proportionate participation rights of each security type in the Company's undistributed income. The Series A Preferred Stock and the Series B Preferred Stock are treated as one class for purposes of applying the two-class method, because they have substantially equal rights and share equally on an as converted basis with respect to income available to WMIH common stockholders. Basic net income (loss) per common share is computed by dividing net income (loss) applicable to WMIH’s common stockholders by the weighted-average number of common shares outstanding for the period after subtracting the weighted-average of any unvested restricted shares outstanding, as these are subject to repurchase. Basic net income (loss) attributable to common stockholders is computed by deducting preferred dividends and the basic calculation of undistributed earnings attributable to participating securities from net income. Diluted net income per common share is computed by dividing net income applicable to WMIH’s common stockholders by the weighted-average number of common shares outstanding during the period after subtracting the weighted-average of any unvested restricted shares outstanding, as these are subject to repurchase and adding any potentially dilutive WMIH common stock equivalents outstanding during the period. Diluted net income attributable to common stockholders is computed by deducting preferred dividends and the diluted calculation of undistributed earnings attributable to participating securities from net income. If common share equivalents exist, in periods where there is a net loss, diluted loss per common share would be equal to or less than basic net loss per common share, since the effect of including any common share equivalents would be antidilutive.
Equity Based Compensation	Equity-Based Compensation On May 22, 2012, WMIH’s Board of Directors (the “Board” or “Board of Directors”) approved the Company’s 2012 Long-Term Incentive Plan (the “2012 Plan”) so that awards of restricted stock could be made to its non-employee directors and to have a plan in place for awards of equity based compensation to executives and others in connection with the Company’s operations and future strategic plans. A total of 2.0 million shares of WMIH’s common stock were initially reserved for future issuance under the 2012 Plan, which became effective upon the Board approval on May 22, 2012. On February 10, 2014, the Board approved and adopted a First Amendment to the 2012 Plan, pursuant to which the number of shares of WMIH’s common stock reserved and available for grants under the 2012 Plan was increased from 2.0 million shares to 3.0 million shares, and the terms of the 2012 Plan were modified to permit such an increase through action of the Board, except when stockholder approval is necessary to comply with any applicable law, regulation or rule of any stock exchange on which WMIH’s shares are listed, quoted or traded. On February 25, 2015, the number of shares authorized and available for awards under the 2012 Plan was increased from 3.0 million to 12.0 million shares of WMIH’s common stock, subject to approval of stockholders of WMIH. This approval was received at the Company’s Annual Meeting of Stockholders on April 28, 2015. The 2012 Plan provides for the granting of restricted shares and other cash and share based awards. The value of restricted stock is generally determined using the fair market value determined to be the trading price at the close of business on the respective date the awards were granted.
Income Taxes	Income Taxes The Company follows the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future income tax consequences attributable to differences between the carrying amounts and tax bases of assets and liabilities and losses carried forward and tax credits. Deferred tax assets and liabilities are measured using enacted tax rates and laws applicable to the years in which the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided to the extent that it is more likely than not that deferred tax assets will not be realized. The Company recognizes the financial statement effects of a tax position when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. Penalties and interest, of which there are none, would be reflected in income tax expense. Tax years are open to the extent the Company has net operating loss (“NOL”) carry-forwards available to be utilized currently.
Dividend Policy	Dividend Policy WMIH has paid no dividends on its common stock on or after the Effective Date and currently has no plans to pay a dividend on its common stock. WMIH has declared and paid $18.0 million and $17.0 million of dividends on its Series B Preferred Stock during the years ended December 31, 2016 and December 31, 2015, respectively. An additional $0.7 million of dividends were accrued as of December 31, 2016 and December 31, 2015, respectively, based on the Series B Preferred Stock dividends that accrue at a rate of 3% per year. The Series B Preferred Stock was issued on January 5, 2015; therefore, no dividends were due or paid for any prior period.
New Accounting Pronouncements	New Accounting Pronouncements In November 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-18—Statement of Cash Flows (Topic 230): Restricted Cash. This update contains amendments that are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. Stakeholders indicated that diversity exists in the classification and presentation of changes in restricted cash on the statement of cash flows under Topic 230, Statement of Cash Flows. Entities classify transfers between cash and restricted cash as operating, investing, or financing activities, or as a combination of those activities, in the statement of cash flows. Also, some entities present direct cash receipts into, and direct cash payments made from, a bank account that holds restricted cash as cash inflows and cash outflows, while others disclose those cash flows as noncash investing or financing activities. This Update addresses that diversity. The Company has reviewed this standard and determined that it is not expected to have a material impact on the Company’s consolidated financial position, results of operations or disclosure requirements, except as they relate to restricted cash in the statement of cash flows.
Fixed Maturities [Member]
Fixed-Maturity Securities	Fixed-Maturity Securities Fixed-maturity securities consist of U.S. Treasury securities, obligations of U.S. government sponsored agencies, and domestic and foreign corporate debt securities. Fixed-maturity securities held in trust are for the benefit of the primary insurers as more fully described in Note 3: Insurance Activity. Investments in fixed-maturity securities are reported at their estimated fair values and are classified as trading securities in accordance with applicable accounting guidance. Realized gains and losses on the sale of fixed-maturity securities are determined using the specific identification method and are reported as a component of net investment income within the consolidated statements of operations.
