Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Reporting	Basis of Reporting The accompanying unaudited interim condensed consolidated financial statements include the accounts of National General Holdings Corp. and its subsidiaries (the “Company” or “NGHC”) and have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial statements and with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the U.S. Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. These interim condensed consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, previously filed with the SEC on February 20, 2020. The balance sheet at December 31, 2019, has been derived from the audited consolidated financial statements at that date. These interim condensed consolidated financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the interim period and all such adjustments are of a normal recurring nature. The results of operations for the interim period are not necessarily indicative, if annualized, of those to be expected for the full year. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates. The unaudited condensed consolidated financial statements include the accounts and operations of Adirondack Insurance Exchange, a New York reciprocal insurer, and New Jersey Skylands Insurance Association, a New Jersey reciprocal insurer (together with Mountain Valley Indemnity Company, a subsidiary of Adirondack Insurance Exchange, the “Reciprocal Exchanges” or “Exchanges”); variable interest entities (“VIE”) of which the Company is the primary beneficiary. The Company has no ownership interest in the Reciprocal Exchanges but is paid a fee to manage their business operations and has the ability to direct their activities through its wholly-owned management companies. The Reciprocal Exchanges are property and casualty insurers. A detailed description of the Company’s significant accounting policies and management judgments is located in the notes to the audited consolidated financial statements, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, filed with the SEC. In March 2020, the outbreak of COVID-19 caused by a novel strain of the coronavirus was recognized as a pandemic by the World Health Organization. The pandemic outbreak has caused an economic downturn on a global scale. The Company continues to monitor the impact of the pandemic as it unfolds. As of June 30, 2020, and for the three and six months ended June 30, 2020, the Company did not experience a material adverse impact due to COVID-19, and cannot, at this time, predict the impact the pandemic will have on its future consolidated financial position, cash flows or results of operations.

Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted During 2020 Standard Description Date of Adoption Effect on the Company ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, and related amendments. This standard changed the impairment model to a new forward-looking expected loss model for most financial assets and certain other instruments. The standard requires immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets, which generally results in earlier recognition of allowances for credit losses on loans and other financial instruments. Many of the loss estimation techniques applied prior the adoption of the standard are still permitted, although the inputs to those techniques changed to reflect the full amount of expected credit losses. The Company continues to use judgement to determine which loss estimation method is appropriate for its circumstances. The standard became effective for interim and annual reporting periods beginning after December 15, 2019 and requires using a modified retrospective approach, recognizing a cumulative-effect adjustment as of the beginning of the first reporting period in which the standard is effective. January 1, 2020 The Company adopted ASU 2016-13 using the modified retrospective approach and recorded a cumulative-effect adjustment, net of tax of $1,010 to the opening balance of retained earnings and increased the allowance for premiums receivable, reinsurance recoverable and deferred taxes by the same amount. ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This standard established a one-step process for testing the value of the goodwill which an entity carries. ASU 2017-04 requires the goodwill impairment to be measured as the excess of the reporting unit’s carrying amount over its fair value. January 1, 2020 The adoption of ASU 2017-04 did not have a material impact on the Company’s condensed consolidated financial statements. With the exception of the adopted accounting pronouncements discussed above, there have been no recent accounting pronouncements, or quantitative or qualitative progress made toward implementation of outstanding accounting pronouncements during the six months ended June 30, 2020, as compared to those described in Note 2, “Significant Accounting Policies” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, that are of significance, or potential significance, to the Company. Accounting Policies The following accounting policies have been updated to reflect the Company's adoption of Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments as described above. Premiums and Other Receivables also was updated to include the accounting of the premium refund. Investment Impairments The Company conducts a periodic review to identify and evaluate invested assets that may have credit impairments. Beginning on January 1, 2020, credit losses on available-for-sale debt securities are recognized through an allowance account. See Note 4, “Investments” for additional information. The Company reports accrued investment income separately from debt securities in the Condensed Consolidated Balance Sheets, and has elected not to measure an allowance for credit losses. Accrued investment income is written off by reversing interest income through net investment income at the time the issuer of the bond defaults or is expected to default on payments. Uncollectible debt securities are written-off to net gain (loss) on investments when the Company determines that no additional payments of principal or interest will be received. Premiums and Other Receivables The Company recognizes earned premium on a pro rata basis over the terms of the policies, generally periods of six or twelve months. Unearned premiums represent the portion of premiums written applicable to the unexpired terms of the policies. Premium refunds are recorded against gross premium written. Premiums and other receivables are reported net of an allowance for expected credit losses. The allowance is based upon the Company’s ongoing review of amounts outstanding, historical loss data, including delinquencies and write-offs, current and forecasted economic conditions, and other relevant factors. The Company uses a loss-rate method to estimate the expected credit losses. Credit risk is partially mitigated by the Company’s ability to cancel the policy if the policyholder does not pay the premium. Reinsurance Recoverable Amounts recoverable from reinsurers are estimated in a manner consistent with the associated claim liability. The Company reports its reinsurance recoverable net of an allowance for estimated uncollectible reinsurance. The allowance is based upon the Company’s ongoing review of amounts outstanding, length of collection periods, changes in reinsurer credit standing, applicable coverage defenses, and other relevant factors. The Company evaluates and monitors the financial condition of its reinsurers under voluntary reinsurance arrangements to minimize its exposure to significant losses from reinsurer insolvencies.

There were 267 and 1,337 individual security lots at June 30, 2020, and December 31, 2019, respectively, that accounted for the gross unrealized loss. As of June 30, 2020, and December 31, 2019, the unrealized losses for those securities in unrealized loss positions for a period of twelve or more consecutive months were not greater than or equal to 25% of their amortized cost. The Company recorded a credit loss allowance of $2,927 on seven securities in the energy sector as of March 31, 2020; however, market improvements have resulted in $1,724 of the allowance being reversed as of June 30, 2020. Some of the factors considered in assessing credit loss and impairment of fixed maturities due to credit-related factors include: (1) the magnitude of the unrealized loss in relation to the amortized cost; (2) the credit rating of the issuing entity and market or issuer events that could impact the issuer’s ability to repay the debt security; (3) the likelihood of the recoverability of principal and interest; and (4) whether it is more likely than not that the Company will be required to sell the investment prior to an anticipated recovery in value. The Company did not record any new credit loss during the three months ended June 30, 2020. The following tables display the roll forward of the allowance for credit losses: Three Months Ended June 30, 2020 Corporate bonds Total Balance, beginning of the period $ 2,927 $ 2,927 Decreases to the allowance for credit losses (1) (1,724) (1,724) Balance, end of the period $ 1,203 $ 1,203 Six Months Ended June 30, 2020 Corporate bonds Total Balance, beginning of the period $ — $ — Additions to the allowance for credit losses on securities not previously recorded (1) 2,927 2,927 Decreases to the allowance for credit losses (1) (1,724) (1,724) Balance, end of the period $ 1,203 $ 1,203 (1) Current period increases or decreases for expected losses are recorded in net gain (loss) on investments.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company carries certain financial instruments at fair value. Assets and liabilities recorded at fair value in the Condensed Consolidated Balance Sheets are measured and classified in accordance with a fair value hierarchy consisting of three “levels” based on the observability of valuation inputs: Level 1 - Inputs are quoted prices in active markets for identical assets or liabilities as of the measurement date. Additionally, the entity must have the ability to access the active market and the quoted prices cannot be adjusted by the entity. Level 2 - Inputs are other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices in active markets for similar assets or liabilities; quoted prices in inactive markets for identical or similar assets or liabilities; or inputs that are observable or can be corroborated by observable market data by correlation or other means for substantially the full term of the assets or liabilities. Level 3 - Unobservable inputs are supported by little or no market activity. The unobservable inputs represent management’s best assumptions of how market participants would price the assets or liabilities. Generally, Level 3 assets and liabilities are valued using pricing models, discounted cash flow methodologies, or similar techniques that require significant judgment or estimation. The following describes the valuation techniques used by the Company to determine the fair value measurements on a recurring basis of financial instruments held as of June 30, 2020, and December 31, 2019. The Company utilizes a pricing service (“pricing service”) to estimate fair value measurements for all its debt and equity securities. Level 1 measurements: • U.S. Treasury and federal agencies. The fair values of U.S. government securities are based on quoted market prices in active markets. The Company believes the market for U.S. government securities is an actively traded market given the high level of daily trading volume. • Short-term investments. Comprised of money market funds that are traded in active markets and fair values are based on quoted market prices. • Other Investments, at fair value. Common and preferred equity securities. The pricing service utilizes market quotations for equity securities that have quoted market prices in active markets and their respective quoted prices are provided at fair value. Level 2 measurements: • States and political subdivision bonds, and foreign government. The primary inputs to the valuation include quoted prices for identical or similar assets in markets that are not active. • Corporate bonds. Comprised of bonds issued by corporations, public and privately placed. The fair values of short-term corporate bonds are priced using the spread above the London Interbank Offering Rate (“LIBOR”) yield curve, and the fair value of long-term corporate bonds are priced using the spread above the risk-free yield curve. The spreads are sourced from broker dealers, trade prices and the new issue market. Where pricing is unavailable from pricing services, the Company obtains non-binding quotes from broker-dealers. The primary inputs to the valuation include quoted prices for identical or similar assets in markets that are not active. • Residential and commercial mortgage-backed securities, asset-backed securities and structured securities. The primary inputs to the valuation include quoted prices for identical or similar assets in markets that are not active, contractual cash flows, benchmark yields, prepayment speeds, collateral performance and credit spreads. Level 3 measurements: • States and political subdivision bonds. The Company holds certain municipal bonds that finance economic development, infrastructure and environmental projects which do not have an active market. These bonds are valued based on non-binding broker quotes where the inputs have not been corroborated to be market observable. • Corporate bonds. The Company holds certain structured notes and term loans that do not have an active market. These bonds are valued based on non-binding broker quotes where the inputs have not been corroborated to be market observable. • Other investments, at fair value. Comprised of the Company’s right to receive the Excess Servicing Spread (“ESS”) related to servicing rights. The Company uses a discounted cash flow method to estimate the fair value of the ESS. The key inputs used in the estimation of ESS include prepayment speed and discount rate. Changes in the fair value of the ESS are recorded in net investment income . • Other Investments, at cost or amortized cost. From time to time, the Company also holds certain equity securities that are issued by privately-held entities or direct equity investments that do not have an active market. The Company estimates the fair value of these securities primarily based on inputs such as third-party broker quotes, issuers’ book value, market multiples, and other inputs. These bonds are valued based on non-binding broker quotes where the inputs have not been corroborated to be market observable. Assets measured at fair value on a recurring basis are as follows: June 30, 2020 Level 1 Level 2 Level 3 Total Debt securities, available-for-sale: U.S. Treasury $ 61,022 $ — $ — $ 61,022 Federal agencies 565 — — 565 States and political subdivision bonds — 302,814 2,519 305,333 Foreign government — 1,845 — 1,845 Corporate bonds — 2,168,133 5,306 2,173,439 Residential mortgage-backed securities — 1,150,462 — 1,150,462 Commercial mortgage-backed securities — 643,419 — 643,419 Asset-backed securities — 42,997 — 42,997 Structured securities — 202,449 — 202,449 Total debt securities, available-for-sale 61,587 4,512,119 7,825 4,581,531 Short-term investments 196,484 20,000 — 216,484 Other investments 4,811 — 3,921 8,732 Total $ 262,882 $ 4,532,119 $ 11,746 $ 4,806,747 NGHC $ 229,695 $ 4,225,203 $ 11,746 $ 4,466,644 Reciprocal Exchanges 33,187 306,916 — 340,103 Total $ 262,882 $ 4,532,119 $ 11,746 $ 4,806,747 December 31, 2019 Level 1 Level 2 Level 3 Total Debt securities, available-for-sale: U.S. Treasury $ 67,006 $ — $ — $ 67,006 Federal agencies 3,915 — — 3,915 States and political subdivision bonds — 298,582 3,100 301,682 Foreign government — 1,802 — 1,802 Corporate bonds — 1,908,235 8,328 1,916,563 Residential mortgage-backed securities — 1,277,460 — 1,277,460 Commercial mortgage-backed securities — 612,193 — 612,193 Asset-backed securities — 75,611 — 75,611 Structured securities — 220,126 — 220,126 Total debt securities, available-for-sale 70,921 4,394,009 11,428 4,476,358 Short-term investments 59,953 7,400 — 67,353 Other investments 4,881 — 4,484 9,365 Total $ 135,755 $ 4,401,409 $ 15,912 $ 4,553,076 NGHC $ 116,602 $ 4,091,068 $ 15,912 $ 4,223,582 Reciprocal Exchanges 19,153 310,341 — 329,494 Total $ 135,755 $ 4,401,409 $ 15,912 $ 4,553,076 For the six months ended June 30, 2020, and 2019, there were no transfers between Level 2 and Level 3.

Unpaid Losses and Loss Adjustme

Unpaid Losses and Loss Adjustment Expense Reserves	6 Months Ended

Insurance [Abstract]
Unpaid Losses and Loss Adjustment Expenses	Unpaid Losses and Loss Adjustment Expense Reserves The unpaid losses and loss adjustment expense (“LAE”) reserves are an estimate of the Company’s liability from incurred claims at the end of the reporting period. The unpaid losses and loss adjustment expense reserves are the result of an ongoing analysis of recent loss development trends and emerging historical experience. Original estimates are increased or decreased as additional information becomes known regarding individual claims. In setting its reserves, the Company reviews its loss data to estimate expected loss development. Management believes that its use of standard actuarial methodology applied to its analyses of its historical experience provides a reasonable estimate of future losses. However, actual future losses may differ from the Company’s estimate, and may be affected by future events beyond the control of management, including inflation, which may favorably or unfavorably impact the ultimate settlement of the Company’s losses and LAE, as well as changes in the law and judicial interpretations. The anticipated effect of inflation is implicitly considered when estimating liabilities for losses and LAE. In addition to inflation, the average severity of claims is affected by a number of factors that may vary by types and features of policies written. Future average severities are projected from historical trends, adjusted for implemented changes in underwriting standards and policy provisions, as well as general economic trends. These estimated trends are monitored and revised as necessary based on actual development.

Reinsurance

Insurance [Abstract]
Reinsurance	Reinsurance The Company utilizes various excess of loss, quota share, state-based industry pools or facilities, and catastrophe reinsurance programs to limit its exposure. Reinsurance agreements transfer portions of the underlying risk of the business the Company writes. Reinsurance does not discharge or diminish the Company’s obligation to pay claims covered by the insurance policies it issues; however, it does permit the Company to recover certain incurred losses from its reinsurers and the Company’s reinsurance recoveries reduce the maximum loss that it may incur as a result of a covered loss event. The Company’s reinsurers generally carry at least an A.M. Best rating of “A-” (Excellent) or the reinsurance recoverable balances are collateralized. The Company also maintains funds held liabilities under the auto quota share reinsurance agreement. The total amount, cost and limits relating to the reinsurance coverage the Company purchases may vary from year to year based upon a variety of factors, including the availability of quality reinsurance at an acceptable price and the level of risk that the Company chooses to retain for its account. The Company assumes and cedes insurance risks under various reinsurance agreements, on both a pro-rata basis and excess of loss basis. The Company purchases reinsurance to mitigate the volatility of direct and assumed business, which may be caused by the aggregate value or the concentration of written exposures in a particular geographic area or business segment and may arise from catastrophes or other events. The Company pays a premium as consideration for ceding the risk. Reinsurance recoverable is as follows: June 30, 2020 December 31, 2019 Reinsurance recoverable on paid losses $ 202,595 $ 282,500 Reinsurance recoverable on unpaid losses 1,090,558 1,111,808 Allowance for uncollectible reinsurance (517) — Reinsurance recoverable, net $ 1,292,636 $ 1,394,308 The following is the effect of reinsurance on unpaid loss and LAE reserves and unearned premiums: June 30, 2020 December 31, 2019 Assumed Ceded Assumed Ceded Unpaid Loss and LAE reserves $ 45,123 $ 1,090,558 $ 50,884 $ 1,111,808 Unearned premiums 18,590 518,082 15,278 575,747 The following is the effect of reinsurance on premiums and loss and LAE: Three Months Ended June 30, Six Months Ended June 30, 2020 2019 2020 2019 Premiums: Written Earned Written Earned Written Earned Written Earned Direct $ 1,324,549 $ 1,370,172 $ 1,293,591 $ 1,356,695 $ 2,783,082 $ 2,760,322 $ 2,782,779 $ 2,672,400 Assumed 17,052 15,654 20,317 19,843 35,073 31,760 40,907 40,843 Total Gross Premium 1,341,601 1,385,826 1,313,908 1,376,538 2,818,155 2,792,082 2,823,686 2,713,243 Ceded (326,693) (320,259) (318,510) (345,887) (593,644) (651,309) (663,624) (718,435) Net Premium $ 1,014,908 $ 1,065,567 $ 995,398 $ 1,030,651 $ 2,224,511 $ 2,140,773 $ 2,160,062 $ 1,994,808 Three Months Ended June 30, Six Months Ended June 30, 2020 2019 2020 2019 Assumed Ceded Assumed Ceded Assumed Ceded Assumed Ceded Loss and LAE $ 7,136 $ 190,165 $ 11,324 $ 150,709 $ 13,771 $ 386,651 $ 16,646 $ 360,031 Industry Pools and Facilities The Company’s reinsurance programs include premiums written under state-mandated involuntary plans for automobile, motorcycle and commercial vehicles and premiums ceded to state-provided reinsurance facilities such as Michigan Catastrophic Claims Association (“MCCA”) and North Carolina Reinsurance Facility (“NCRF”), for which the Company retains no loss indemnity risk. Prepaid reinsurance premiums are recognized on a pro-rata basis over the period of risk, consistent with premiums written. The Company believes that it is unlikely to incur any material loss as a result of non-payment of amounts owed to the Company by MCCA and NCRF because (i) the payment obligations are extended over many years, resulting in relatively small current payment obligations, (ii) both MCCA and NCRF are supported by assessments permitted by statute, and (iii) the Company has not historically incurred losses as a result of non-payment. Because MCCA and NCRF are supported by assessments permitted by statute, and there have been no significant and uncollectible balances from MCCA and NCRF, the Company believes that it has no significant exposure to uncollectible reinsurance balances from these entities. Quota Share Agreements In 2017, the Company entered into an Auto Quota Share Agreement (the “Auto Quota Share Agreement”) covering the Company’s auto lines of business. Effective January 1, 2019, the Company ceded 7.0% of net liability. On July 1, 2019, the Company renewed its Auto Quota Share Agreement for a two-year term. Effective July 1, 2019, the Company ceded 10.0% of net liability with the ability to increase the cession to up to 30.0% and decrease the cession down to 5.0% under certain conditions. The Company receives a 31.2% provisional ceding commission on premiums ceded to the reinsurer during the term of the Auto Quota Share Agreement, subject to a sliding scale adjustment to a maximum of 32.8% if the loss ratio for the reinsured business is 64.7% or less and a minimum of 30.0% if the loss ratio is 67.5% or higher. Effective January 1, 2020, the Company cedes 5.0% of net liability under new and renewal auto policies written. In 2017, the Company entered into a Homeowners Quota Share Agreement (the “HO Quota Share Agreement”) covering the Company’s homeowners line of business. On July 1, 2019, the Company renewed its HO Quota Share Agreement for a one-year term. Effective July 1, 2019, the Company ceded 40.0% of net liability and received a 36.0% ceding commission on new and renewal business and a portion of the in-force business. A portion of the in-force business is being run-off under the prior agreements. On July 1, 2020, the Company renewed its HO Quota Share Agreement for a one-year term. Effective July 1, 2020, the Company cedes 20.0% of net liability and receives a 37.0% ceding commission on in-force, new and renewal business. In 2019, the Reciprocal Exchanges entered into a personal lines quota share agreement for a one-year term. The Reciprocal Exchanges ceded 42.3% of net liability on new and renewal homeowners multiple peril, dwelling fire, and automobile physical damage (comprehensive only) policies written in the states of New Jersey and New York. Effective July 1, 2020, the Reciprocal Exchanges renewed their personal lines quota share agreement for a one-year term, ceding 42.0% combined weighted average of net liability. This includes a 55.0% quota share covering homeowners multiple peril, dwelling fire, and automobile physical damage (comprehensive only) policies written in the states of New Jersey and New York as well as a 25.0% quota share on automobile liability and collision coverages. Catastrophe and Casualty Reinsurance Effective May 1, 2020, with additional purchases made at June 1, 2020, and July 1, 2020, the Company renewed its property catastrophe excess of loss program, protecting the Company against catastrophic events and other large losses. The mainframe treaty provides coverage up to $650,000 with one reinstatement. The mainframe treaty attaches at $70,000 for the first event and $50,000 for the second event. The Company purchased additional first event coverage for named wind that attaches at $50,000. Effective July 17, 2020, the Company purchased an additional $115,000 of top layer coverage. Effective October 1, 2019, the Company’s casualty program provides $35,000 in coverage in excess of a $5,000 retention. The Company pays a premium as consideration for ceding the risk. Effective July 1, 2020, the Reciprocal Exchanges’ property catastrophe excess of loss program provided coverage up to $475,000 with a $20,000 retention, and one reinstatement. Effective July 17, 2020, the Company purchased an additional $125,000 of top layer coverage.

The Subordinated Debentures require interest-only payments to be made on a quarterly basis, with principal due at maturity. The Subordinated Debentures’ principal amounts of $41,238 and $30,930 mature on 2035 and 2037, respectively, and bear interest at an annual rate equal to LIBOR plus 3.40% and LIBOR plus 4.25%, respectively.

The 2019 Credit Agreement is currently a $340,000 base revolving credit facility with a letter of credit sublimit of $150,000 and an expansion feature of up to $50,000. Borrowings under the 2019 Credit Agreement bear interest at either the Alternate Base Rate (“ABR”) or the LIBOR rate.

Eurodollar borrowings under the 2019 Credit Agreement will bear interest at the adjusted LIBOR rate plus the Eurodollar spread for the interest period in effect. Fees payable by the Company under the 2019 Credit Agreement include a letter of credit participation fee, a letter of credit fronting fee with respect to each letter of credit (0.125%) and a commitment fee on the available commitments of the lenders (a range of 0.175% to 0.25% based on the Company’s consolidated leverage ratio; and as of June 30, 2020, the rate was 0.225% ).

The 2019 Credit Agreement contains certain restrictive covenants customary for facilities of this type (subject to negotiated exceptions and baskets), including restrictions on indebtedness, liens, acquisitions and investments, restricted payments and dispositions. There are also financial covenants that require the Company to maintain a minimum consolidated net worth, a maximum consolidated leverage ratio, a minimum risk-based capital and a minimum rating. The 2019 Credit Agreement also provides for customary events of default, with grace periods where customary, including failure to pay principal when due, failure to pay interest or fees within three business days after becoming due, failure to comply with covenants, breaches of representations and warranties, default under certain other indebtedness, certain insolvency or receivership events affecting the Company and its subsidiaries, the occurrence of certain material judgments, or a change in control of the Company.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Litigation The Company is routinely involved in legal proceedings arising in the ordinary course of business, in particular in connection with claims adjudication with respect to its policies. Management believes it has recorded adequate reserves for these liabilities and that there is no individual case pending that is likely to have a material adverse effect on our financial condition or results of operations. On July 25, 2019, the City of North Miami Beach Police Officers’ and Firefighters’ Retirement Plan filed a complaint in the U.S. District Court for the Central District of California against the Company and certain of its officers. On November 19, 2019, the U.S. District Court for the Central District of California granted the Company’s Motion to Transfer the case to the Southern District of New York. On January 10, 2020, lead plaintiffs Town of Davie Police Officers Retirement System and Massachusetts Laborers’ Pension Fund filed an amended Complaint asserting claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 promulgated thereunder based on allegedly false and misleading statements made by the Company in its SEC filings in relationship to the Company’s involvement in the historical and no longer existing Wells Fargo collateral protection insurance program on behalf of a purported class of individuals and entities who purchased or otherwise acquired shares of the Company’s common stock between July 15, 2015, and August 9, 2017. The amended complaint seeks damages in an amount to be proven at trial. The Company filed a Motion to Dismiss the amended complaint on March 10, 2020. Management believes that the claims set forth in the amended complaint are unfounded and without merit and intends to vigorously contest them. The Company notes, however, that in light of the inherent uncertainty in legal proceedings, the Company can give no assurance as to the ultimate resolution of the matter, and an estimate of the possible loss or range of loss, if any, cannot be made at this time.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company files a consolidated Federal income tax return. The Reciprocal Exchanges are not included in the Company’s consolidated tax return as the Company does not have an ownership interest in the Reciprocal Exchanges, and they are not a part of the consolidated tax sharing agreement among the Company and its subsidiaries. The Company uses the estimated annual effective tax rate method. Certain items, including those deemed to be unusual, infrequent or that cannot be reliably estimated, are excluded from the estimated annual effective tax rate. In these cases, the actual tax expense or benefit is reported in the same period as the related item. Certain tax effects are also not reflected in the estimated annual effective tax rate, primarily certain changes in the realizability of deferred tax assets and uncertain tax positions. The Company’s consolidated effective tax rate was 22.4% for both the three months ended June 30, 2020, and 2019. The Company’s consolidated effective tax rate increased to 22.2% for the six months ended June 30, 2020, from 21.6% for the six months ended June 30, 2019. The increase in consolidated effective tax rate for the six months ended June 30, 2020, was primarily driven by an increase in tax associated with U.S shareholder’s income and other nondeductible items. All tax liabilities are payable to the Internal Revenue Service (“IRS”) and various state and local taxing agencies. The Company’s subsidiaries are currently under audit by the IRS for the years ended December 31, 2016, 2017 and 2018, and open to audit years thereafter for federal tax purposes. For state and local tax purposes, the Company is open to audit for tax years ended December 31, 2016, and forward, depending on jurisdiction. On March 27, 2020, the U.S. enacted the Coronavirus Aid, Relief and Economic Security Act (the “CARES” Act) to mitigate the economic impacts of COVID-19. The Company believes that the provisions of the CARES Act will not have a material impact on its U.S. federal tax liabilities.

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation In 2019, the Company’s stockholders approved the 2019 Omnibus Incentive Plan (the “2019 Plan”). The 2019 Plan authorizes up to 2.5 million shares of the Company’s stock for awards of stock options, stock appreciation rights, restricted stock, restricted stock units (“RSUs”), performance share units, performance units, cash-based awards or other stock-based awards. The number of shares of common stock for which awards may be issued may not exceed 2.5 million shares, subject to the authority of the Company’s Board of Directors to adjust this amount in the event of a consolidation, reorganization, stock dividend, recapitalization or similar transaction affecting the Company’s common stock. The 2019 Plan serves as a successor of the Company’s prior equity incentive plans. Outstanding awards under the prior plans continue to be outstanding and subject to their terms and conditions. As of June 30, 2020, approximately 1.9 million shares of the Company’s common stock remained available for grants under the 2019 Plan. Stock Options A summary of the stock option awards granted under the prior plan is shown below: Shares Subject to Options Outstanding Six Months Ended June 30, 2020 Number of Shares Weighted- Weighted-Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (1) Outstanding at beginning of the period 3,025,587 $ 9.83 Exercised (218,622) 3.82 Outstanding and exercisable at end of the period 2,806,965 $ 10.30 2.8 $ 31,750 (1) The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying stock option awards and the closing price of the Company’s common stock of $21.61, as reported on the Nasdaq Global Market on June 30, 2020. No options were granted, forfeited or expired during the six months ended June 30, 2020. The total intrinsic value of the options exercised for the three months ended June 30, 2020, and 2019, was $1,633 and $749, respectively. The total intrinsic value of the options exercised for the six months ended June 30, 2020, and 2019, was $3,759 and $1,275, respectively.

Segment Information

Segment Reporting [Abstract]
Segment Information	Segment Information The Company currently operates two business segments, “Property and Casualty” and “Accident and Health.” The “Corporate and Other” column represents the activities of the holding company, as well as income from the Company’s investment portfolio. The Company evaluates segment profits attributable to the performance of activities within the segment separately from the results of the Company’s investment portfolio. Other operating expenses allocated to the segments are called “General and administrative expenses” which are allocated on an actual basis except corporate salaries and benefits where management’s judgment is applied. In determining total assets by segment, the Company identifies those assets that are attributable to a particular segment such as premiums receivable, deferred acquisition costs, reinsurance recoverable, prepaid reinsurance premiums, intangible assets and goodwill, while the remaining assets are allocated to Corporate and Other. The Property and Casualty segment, which includes the Reciprocal Exchanges and the management companies, reports the management fees earned by the Company from the Reciprocal Exchanges for underwriting, investment management and other services as service and fee income. The effects of these transactions between the Company and the Reciprocal Exchanges are eliminated in consolidation to derive consolidated net income. However, the management fee income is reported in net income attributable to NGHC and included in the basic and diluted earnings per share. The following tables summarize the results of operations of the operating segments: Three Months Ended June 30, 2020 Property Accident Corporate Total Underwriting revenues: Gross premium written $

Accounting Policies [Abstract]
Basis of Accounting, Policy	The accompanying unaudited interim condensed consolidated financial statements include the accounts of National General Holdings Corp. and its subsidiaries (the “Company” or “NGHC”) and have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial statements and with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the U.S. Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. These interim condensed consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, previously filed with the SEC on February 20, 2020. The balance sheet at December 31, 2019, has been derived from the audited consolidated financial statements at that date. These interim condensed consolidated financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the interim period and all such adjustments are of a normal recurring nature. The results of operations for the interim period are not necessarily indicative, if annualized, of those to be expected for the full year. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates. The unaudited condensed consolidated financial statements include the accounts and operations of Adirondack Insurance Exchange, a New York reciprocal insurer, and New Jersey Skylands Insurance Association, a New Jersey reciprocal insurer (together with Mountain Valley Indemnity Company, a subsidiary of Adirondack Insurance Exchange, the “Reciprocal Exchanges” or “Exchanges”); variable interest entities (“VIE”) of which the Company is the primary beneficiary. The Company has no ownership interest in the Reciprocal Exchanges but is paid a fee to manage their business operations and has the ability to direct their activities through its wholly-owned management companies. The Reciprocal Exchanges are property and casualty insurers. A detailed description of the Company’s significant accounting policies and management judgments is located in the notes to the audited consolidated financial statements, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, filed with the SEC.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted During 2020 Standard Description Date of Adoption Effect on the Company ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, and related amendments. This standard changed the impairment model to a new forward-looking expected loss model for most financial assets and certain other instruments. The standard requires immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets, which generally results in earlier recognition of allowances for credit losses on loans and other financial instruments. Many of the loss estimation techniques applied prior the adoption of the standard are still permitted, although the inputs to those techniques changed to reflect the full amount of expected credit losses. The Company continues to use judgement to determine which loss estimation method is appropriate for its circumstances. The standard became effective for interim and annual reporting periods beginning after December 15, 2019 and requires using a modified retrospective approach, recognizing a cumulative-effect adjustment as of the beginning of the first reporting period in which the standard is effective. January 1, 2020 The Company adopted ASU 2016-13 using the modified retrospective approach and recorded a cumulative-effect adjustment, net of tax of $1,010 to the opening balance of retained earnings and increased the allowance for premiums receivable, reinsurance recoverable and deferred taxes by the same amount. ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This standard established a one-step process for testing the value of the goodwill which an entity carries. ASU 2017-04 requires the goodwill impairment to be measured as the excess of the reporting unit’s carrying amount over its fair value. January 1, 2020 The adoption of ASU 2017-04 did not have a material impact on the Company’s condensed consolidated financial statements. With the exception of the adopted accounting pronouncements discussed above, there have been no recent accounting pronouncements, or quantitative or qualitative progress made toward implementation of outstanding accounting pronouncements during the six months ended June 30, 2020, as compared to those described in Note 2, “Significant Accounting Policies” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, that are of significance, or potential significance, to the Company.
Investment Impairments	Investment Impairments The Company conducts a periodic review to identify and evaluate invested assets that may have credit impairments. Beginning on January 1, 2020, credit losses on available-for-sale debt securities are recognized through an allowance account. See Note 4, “Investments” for additional information. The Company reports accrued investment income separately from debt securities in the Condensed Consolidated Balance Sheets, and has elected not to measure an allowance for credit losses. Accrued investment income is written off by reversing interest income through net investment income at the time the issuer of the bond defaults or is expected to default on payments. Uncollectible debt securities are written-off to net gain (loss) on investments when the Company determines that no additional payments of principal or interest will be received.
Premiums and Other Receivables	Premiums and Other Receivables The Company recognizes earned premium on a pro rata basis over the terms of the policies, generally periods of six or twelve months. Unearned premiums represent the portion of premiums written applicable to the unexpired terms of the policies. Premium refunds are recorded against gross premium written. Premiums and other receivables are reported net of an allowance for expected credit losses. The allowance is based upon the Company’s ongoing review of amounts outstanding, historical loss data, including delinquencies and write-offs, current and forecasted economic conditions, and other relevant factors. The Company uses a loss-rate method to estimate the expected credit losses. Credit risk is partially mitigated by the Company’s ability to cancel the policy if the policyholder does not pay the premium.
Reinsurance Recoverable	Reinsurance Recoverable Amounts recoverable from reinsurers are estimated in a manner consistent with the associated claim liability. The Company reports its reinsurance recoverable net of an allowance for estimated uncollectible reinsurance. The allowance is based upon the Company’s ongoing review of amounts outstanding, length of collection periods, changes in reinsurer credit standing, applicable coverage defenses, and other relevant factors. The Company evaluates and monitors the financial condition of its reinsurers under voluntary reinsurance arrangements to minimize its exposure to significant losses from reinsurer insolvencies.
