Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	1. Organization NI Holdings, Inc. (“NI Holdings”) is a North Dakota business corporation that is the stock holding company of Nodak Insurance Company and became such in connection with the conversion of Nodak Mutual Insurance Company from a mutual to stock form of organization and the creation of a mutual holding company. The conversion was consummated on March 13, 2017. Immediately following the conversion, all of the outstanding shares of common stock of Nodak Insurance Company (the successor to Nodak Mutual Insurance Company) were issued to Nodak Mutual Group, Inc., which then contributed the shares to NI Holdings in exchange for 55% of the outstanding shares of common stock of NI Holdings. Nodak Insurance Company then became a wholly-owned stock subsidiary of NI Holdings. Prior to completion of the conversion, NI Holdings conducted no business and had no assets or liabilities. As a result of the conversion, NI Holdings became the holding company for Nodak Insurance Company and its existing subsidiaries. The newly issued shares of NI Holdings were available for public trading on March 16, 2017. The consolidated financial statements of NI Holdings consist primarily of five entities: Nodak Insurance Company (“Nodak Insurance”, formerly Nodak Mutual Insurance Company prior to the conversion), Nodak Agency, Inc. (“Nodak Agency”), American West Insurance Company (“American West”), Primero Insurance Company (“Primero”), and an affiliated company, Battle Creek Mutual Insurance Company (“Battle Creek”). Nodak Insurance is the largest domestic property and casualty insurance company in North Dakota. Nodak Insurance was incorporated on April 15, 1946 under the laws of North Dakota, and benefits from a strong marketing affiliation with the North Dakota Farm Bureau (“NDFB”). Nodak Insurance specializes in providing private passenger auto, homeowners, farmowners, commercial, crop hail, and Federal multi-peril crop insurance coverages. Nodak Agency, a wholly-owned subsidiary of Nodak Insurance, is an inactive shell corporation. American West, a wholly-owned subsidiary of Nodak Insurance, is a property and casualty insurance company licensed in eight states in the Midwest and Western regions of the United States. American West began writing policies in 2002 and primarily writes personal auto, homeowners, and farm coverages in South Dakota. American West also writes personal auto in North Dakota, as well as crop hail and Federal multi-peril crop insurance coverages in Minnesota and South Dakota. Primero is a wholly-owned subsidiary of Tri-State, Ltd. Tri-State, Ltd. is an inactive shell corporation 100% owned by Nodak Insurance. Primero is a property and casualty insurance company writing non-standard automobile coverage in the states of Nevada, Arizona, North Dakota and South Dakota. Battle Creek is controlled by Nodak Insurance via a surplus note and 100% quota-share agreement. The terms of the surplus note and quota-share agreement allow Nodak Insurance to appoint two-thirds of the Battle Creek Board of Directors. Battle Creek is a property and casualty insurance company writing personal auto, homeowners, and farm coverages solely in the state of Nebraska. The same executive management and underwriting personnel administer products, classes of business, pricing practices, and underwriting standards of Nodak Insurance and its insurance subsidiaries. In addition, the insurance companies share a combined business plan to achieve market penetration and underwriting profitability objectives. Distinctions within the products of the insurance companies generally relate to the states in which the risk is located and specific risk profiles targeted within similar classes of business.

Basis of Presentation	2. Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the interim periods ended June 30, 2018 are not necessarily indicative of the results that may be expected for the year ended December 31, 2018. Our consolidated financial statements include our accounts and those of our wholly-owned subsidiaries, as well as Battle Creek, an entity we control via contract. We have eliminated all significant inter-company accounts and transactions in consolidation. The terms “we”, “us”, “our”, or “the Company” as used herein refer to the consolidated entity.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	3. Summary of Significant Accounting Policies Use of Estimates: In preparing our consolidated financial statements, management makes estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the balance sheet and revenues and expenses for the periods then ended. Actual results could differ significantly from those estimates. We make estimates and assumptions that can have a significant effect on amounts and disclosures we report in our consolidated financial statements. The most significant estimates relate to our reserves for unpaid losses and loss adjustment expenses, earned premiums for crop insurance, valuation of investments, determination of other-than-temporary impairments, valuation allowances for deferred income tax assets, and deferred policy acquisition costs. While we believe our estimates are appropriate, the ultimate amounts may differ from the estimates provided. We regularly review our methods for making these estimates as well as the continuing appropriateness of the estimated amounts, and we reflect any adjustment we consider necessary in our current results of operations. Variable-Interest Entities: Any company deemed to be a variable interest entity (“VIE”) is required to be consolidated by the primary beneficiary of the VIE. We assess our investments in other entities at inception to determine if any meet the qualifications of a VIE. We consider an investment in another company to be a VIE if (a) the total equity investment at risk is not sufficient to permit the entity to finance its activities without additional subordinated financial support, (b) the characteristics of a controlling financial interest are missing (either the ability to make decisions through voting or other rights, the obligation to absorb expected losses of the entity or the right to receive the expected residual returns of the entity), or (c) the voting rights of the equity holders are not proportional to their obligations to absorb the expected losses of the entity and/or the rights to receive the expected residual returns of the entity, and substantially all of the entity’s activities either involve or are conducted on behalf of an investor that has disproportionately few voting rights. Upon the occurrence of certain events, we would reassess our initial determination of whether the investment is a VIE. We evaluate whether we are the primary beneficiary of each VIE and we consolidate the VIE if we have both (1) the power to direct the economically significant activities of the entity and (2) the obligation to absorb losses of, or the right to receive benefits from, the entity. We consider the contractual agreements that define the ownership structure, distribution of profits and losses, risks, responsibilities, indebtedness, voting rights, and board representation of the respective parties in determining whether we qualify as the primary beneficiary. Our assessment of whether we are the primary beneficiary of a VIE is performed at least annually. We control Battle Creek via a 100% quota-share reinsurance agreement between Nodak Insurance and Battle Creek, as well as the ability to control a majority of the Board of Directors of Battle Creek. Through the effects of the 100% quota-share agreement with Battle Creek, we are considered the primary beneficiary of Battle Creek’s operating results excluding investment income, bad debt expense, and income taxes. Therefore, we consolidate the financial statements of Battle Creek, and Battle Creek’s policyholders’ interest in Battle Creek is reflected as a non-controlling interest in Equity in our Consolidated Balance Sheet. Cash and Cash Equivalents: Cash and cash equivalents include certain investments in highly liquid debt instruments with original maturities of three months or less. Cost approximates fair value for these short-term investments. Investments: We have categorized our investment portfolio as “available-for-sale” and have reported the portfolio at fair value, with unrealized gains and losses, net of income taxes, reported in accumulated other comprehensive income. Fair values are based on quoted market prices or dealer quotes, if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities. Amortization of premium and accretion of discount are computed using an effective interest method. Realized gains and losses are determined using the specific identification method and included in the determination of net income. Net investment income includes interest and dividend income together with amortization of purchase premiums and discounts, and is net of investment management and custody fees. We review our investments each quarter to determine whether a decline in fair value below the amortized cost basis is other than temporary. Accordingly, we assess whether we intend to sell or it is more likely than not that we will be required to sell a security before recovery of its amortized cost basis. For fixed income securities that are considered other-than-temporarily impaired and that we do not intend to sell and will not be required to sell prior to recovery of the amortized cost basis, we separate the amount of the impairment into the amount that is credit related (credit loss component) and the amount due to all other factors. The credit loss component is recognized in earnings and is the difference between the security’s amortized cost basis and the present value of its expected future cash flows discounted at the security’s effective yield. The remaining difference between the security’s fair value and the present value of future expected cash flows is due to factors that are not credit related and, therefore, is not required to be recognized as losses in the Consolidated Statement of Operations, but is recognized in other comprehensive income. We classify each fair value measurement at the appropriate level in the fair value hierarchy. The hierarchy gives the highest priority to unadjusted quoted market price in active markets for identical assets or liabilities (Level I measurements) and the lowest priority to unobservable inputs (Level III measurements). An asset’s or liability’s classification within the fair value hierarchy is based on the lowest level of significant input to its valuation. Level I – Quoted price in active markets for identical assets and liabilities. Level II – Quoted prices in markets that are not active or inputs that are observable either directly or indirectly. Level II inputs include quoted prices for similar assets or liabilities other than quoted in prices in Level I, quoted prices in markets that are not active, or other inputs that are observable or can be derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities. Level III – Unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities. Unobservable inputs reflect the reporting entity’s own assumptions that market participants would use in pricing the asset or liability. Level III assets and liabilities include financial instruments whose values are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. Fair Value of Other Financial Instruments: Our other financial instruments, aside from investments, are cash and cash equivalents, premiums and agents’ balances receivable, and accrued expenses and accounts payable. The carrying amounts for cash and cash equivalents, premiums and agents’ balances receivable, and accrued expenses and accounts payable approximate their fair value based on their short-term nature. Other invested assets that do not have observable inputs and little or no market activity are carried on a cost basis. The carrying value of these other invested assets was $1,954 at June 30, 2018 and $1,972 at December 31, 2017. Reclassifications: Certain amounts in the 2017 consolidated financial statements have been reclassified to conform to the 2018 presentation. This includes a change in the Company’s reportable segments that was made in the fourth quarter of the year ended December 31, 2017. The prior segments were non-standard auto, crop, and other property and casualty. The new segments used throughout this report are private passenger auto, non-standard auto, home and farm, crop, and all other. Revenue Recognition: We record premiums written at policy inception and recognize them as revenue on a pro rata basis over the policy term or, in the case of crop insurance, over the period of risk. The portion of premiums that could be earned in the future is deferred and reported as unearned premiums. When policies lapse, the Company reverses the unearned portion of the written premium and removes the applicable unearned premium. Policy-related fee income is recognized when collected. The Company uses the direct write-off method for recognizing bad debts. Accounts are deemed to be delinquent after 60 days except for those accounts associated with amounts due from insureds for premiums, in which case policy cancellation procedures are commenced in accordance with state insurance regulations. Any earned but uncollected premiums are written off immediately upon the effective date of policy cancellation. Policy Acquisition Costs: We defer our policy acquisition costs, consisting primarily of commissions, premium taxes and certain other underwriting costs, reduced by ceding commissions, which vary with and relate directly to the production of business. We amortize these deferred policy acquisition costs over the period in which we earn the premiums. The method we follow in computing deferred policy acquisition costs limits the amount of such deferred costs to their estimated realizable value, which gives effect to the premium to be earned, related investment income, losses and loss adjustment expenses, and certain other costs we expect to incur as we earn the premium. Property and Equipment: We report property and equipment at cost less accumulated depreciation. Depreciation is computed using the straight-line method based upon the estimated useful lives of the assets. Losses and Loss Adjustment Expenses: Liabilities for unpaid losses and loss adjustment expenses are estimates at a given point in time of the amounts we expect to pay with respect to policyholder claims based on facts and circumstances then known. At the time of establishing our estimates, we recognize that our ultimate liability for losses and loss adjustment expenses will exceed or be less than such estimates. We base our estimates of liabilities for unpaid losses and loss adjustment expenses on assumptions as to future loss trends, expected claims severity, judicial theories of liability, and other factors. During the loss adjustment period, we may learn additional facts regarding certain claims, and, consequently, it often becomes necessary for us to refine and adjust our estimates of the liability. We reflect any adjustments to our liabilities for unpaid losses and loss adjustment expenses in our operating results in the period in which we determine the need for a change in the estimates. We maintain liabilities for unpaid losses and loss adjustment expenses with respect to both reported and unreported claims. We establish these liabilities for the purpose of covering the ultimate costs of settling all losses, including investigation and litigation costs. We base the amount of our liability for reported losses primarily upon a case-by-case evaluation of the type of risk involved, knowledge of the circumstances surrounding each claim, and the insurance policy provisions relating to the type of loss our policyholder incurred. We determine the amount of our liability for unreported losses and loss adjustment expenses on the basis of historical information by line of insurance. Inflation is not explicitly selected in the loss reserve analysis. However, historical inflation is embedded in the estimated loss reserving function through analysis of costs and trends and reviews of historical reserving results. We closely monitor our liabilities and update them periodically using new information on reported claims and a variety of statistical techniques. We do not discount our liabilities for unpaid losses and loss adjustment expense. Reserve estimates can change over time because of unexpected changes in assumptions related to our external environment and, to a lesser extent, assumptions as to our internal operations. Assumptions related to our external environment include the absence of significant changes in tort law and the legal environment which may impact liability exposure, the trends in judicial interpretations of insurance coverage and policy provisions, and the rate of loss cost inflation. Internal assumptions include consistency in the recording of premium and loss statistics, consistency in the recording of claims, payment and case reserving methodologies, accurate measurement of the impact of rate changes and changes in policy provisions, consistency in the quality and characteristics of business written within a given line of business, and consistency in reinsurance coverage and collectability of reinsured losses, among other items. To the extent we determine that underlying factors impacting our assumptions have changed, we attempt to make appropriate adjustments for such changes in our reserves. Accordingly, our ultimate liability for unpaid losses and loss adjustment expenses will likely differ from the amount recorded. Income Taxes: With the exception of Battle Creek, which files a stand-alone federal income tax return, we currently file a consolidated federal income tax return. For the year ended December 31, 2016, the consolidated federal income tax return included Nodak Mutual Insurance Company and its wholly-owned subsidiaries. For the year ended December 31, 2017 and thereafter, the consolidated federal income tax return included and will include thereafter NI Holdings and its wholly-owned subsidiaries. The Company reports tax-related interest and penalties, if any, as part of income tax expense in the year such amounts are determinable. We account for deferred income taxes using the asset and liability method. The objective of the asset and liability method is to establish deferred income tax assets and liabilities for the temporary differences between the financial reporting basis and the income tax basis of our assets and liabilities at enacted tax rates expected to be in effect when we realize or settle such amounts. Accounting guidance requires that companies re-measure existing deferred income tax assets (including loss carryforwards) and liabilities when a change in tax rate occurs, and record an offset for the net amount of the change as a component of income tax expense from continuing operations in the period of enactment. The guidance also requires any change to a previously recorded valuation allowance as a result of re-measuring existing temporary differences and loss carryforwards to be reflected as a component of income tax expense from continuing operations. The Company has elected to reclassify any tax effects stranded in accumulated other comprehensive income as a result of a change in income tax rates to retained earnings. Credit Risk: Our primary investment objective is to earn competitive returns by investing in a diversified portfolio of securities. Our portfolio of fixed income securities and, to a lesser extent, short-term investments, is subject to credit risk. We define this risk as the potential loss in fair value resulting from adverse changes in the borrower’s ability to repay the debt. We manage this risk by performing an analysis of prospective investments and through regular reviews of our portfolio by our investment staff and advisors. We also limit the amount of our total investment portfolio that we invest in any one security. Property and liability insurance coverages are marketed through captive agents in North Dakota and through independent insurance agencies located throughout all operating areas. All business is billed directly to policyholders. We maintain cash balances primarily at one bank, which are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250. During the normal course of business, balances are maintained above the FDIC insurance limit. The Company maintains short-term investment balances in investment grade money market accounts that are insured by the Securities Investor Protection Corporation (“SIPC”) up to $500. On occasion, balances for these accounts are maintained in excess of the SIPC insurance limit. Reinsurance: The Company limits the maximum net loss that can arise from large risks or risks in concentrated areas of exposure by reinsuring (ceding) certain levels of risks to other insurers or reinsurers, either on an automatic basis under general reinsurance contracts knows as “treaties” or by negotiation on substantial individual risks. Ceded reinsurance is treated as the risk and liability of the assuming companies. Reinsurance contracts do not relieve the Company from its obligations to policyholders. In the event that all or any of the reinsuring companies might be unable to meet their obligations under existing reinsurance agreements, the Company would be liable for such defaulted amounts. Goodwill and Other Intangible Assets: Goodwill represents the excess of the purchase price over the underlying fair value of acquired entities. When completing acquisitions, we seek also to identify separately identifiable intangible assets that we have acquired. We assess goodwill and intangible assets with an indefinite useful life for impairment annually. We also assess goodwill and other intangible assets for impairment upon the occurrence of certain events. In making our assessment, we consider a number of factors including operating results, business plans, economic projections, anticipated future cash flows, and current market data. Inherent uncertainties exist with respect to these factors and to our judgment in applying them when we make our assessment. Impairment of goodwill and other intangible assets could result from changes in economic and operating conditions in future periods. We did not record any impairments of goodwill or other intangible assets during the three and six month periods ended June 30, 2018 and 2017. Goodwill arising from the acquisition of Primero in 2014 represents the excess of the purchase price over the fair value of the net assets acquired, and is reported separately in the Consolidated Balance Sheet. The purchase price in excess of the fair value of net assets acquired was negotiated at arms-length with an unrelated party and was based upon the strategic decision by Company management to expand both the geographic footprint and product lines of the Company. The nature of the business acquired was such that there were limited intangible assets not reflected in the net assets acquired. The purchase price was paid with a combination of cash and cancellation of obligations owed to the acquired company by the sellers. The goodwill which arose from this transaction is included in the basis of the net assets acquired and is not deductible for income tax purposes.

Acquisition of Direct Auto Insurance Company	4. Acquisition of Direct Auto Insurance Company On May 31, 2018, the Company entered into an agreement to acquire 100% of the stock of Direct Auto Insurance Company (“Direct Auto”) from private shareholders. The agreement contains customary representations, warranties, and covenants by the Company and the other parties to the agreement. Closing of the transaction is expected later this year, subject to the receipt of regulatory approvals and other customary closing conditions. Direct Auto is headquartered in Chicago, Illinois and underwrites specialty automobile insurance in the state of Illinois through independent agents. Following the completion of the transaction, it is expected that the current president (who is also one of the principal shareholders) of Direct Auto will continue to manage the Direct Auto insurance operations along with the current staff and management team. It is expected that Direct Auto will become part of the Company’s non-standard auto business segment as of the closing date. We account for business acquisitions in accordance with the acquisition method of accounting, which requires, among other things, that most assets acquired, liabilities assumed, and contingent consideration be recognized at their fair values as of the acquisition date, which is expected to be the closing date for the Direct Auto transaction. During the measurement period, adjustments to provisional purchase price allocations are recognized if new information is obtained about the facts and circumstances that existed as of the acquisition date that, if known, would have resulted in the recognition of those assets and liabilities as of that date. The measurement period ends as soon as it is determined that no more information is obtainable, but in no case shall the measurement period exceed one year from the acquisition date.

Accounting Policies [Abstract]
Summary of Recent Accounting Pronouncements	5. Recent Accounting Pronouncements As an emerging growth company, we have elected to use the extended transition period for complying with any new or revised financial accounting standards pursuant to Section 13(a) of the Exchange Act. The following discussion includes effective dates for both public business entities and emerging growth companies, as well as whether specific guidance may be adopted early. Adopted On July 1, 2017, the Company early adopted amended guidance from the Financial Accounting Standards Board (the “FASB”) on goodwill impairment testing. Under the amended guidance, the optional qualitative assessment (Step 0) and the first step of the quantitative assessment (Step 1) remain unchanged. Step 2 is eliminated. As a result, for annual impairment testing or in the event a test is required prior to the annual test, the Company will use Step 0 to determine if an impairment might exist and Step 1 to determine the amount of goodwill impairment. An impairment loss will be recognized for the amount by which the reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of goodwill in the reporting unit. This guidance is effective for annual and interim reporting periods beginning after December 15, 2019 for public business entities. For private companies and emerging growth companies, this guidance is also effective for annual and interim reporting periods beginning after December 15, 2021. Early adoption is permitted for all entities beginning in 2017. The Company early adopted this guidance on a prospective basis as a change in accounting principle, therefore at the date of adoption there was no impact to the Company’s financial position or results of operations. In March 2016, the FASB issued amended guidance to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the Consolidated Statement of Cash Flows. All excess income tax benefits and income tax deficiencies should be recognized as income tax expense or benefit in the Consolidated Statement of Operations, instead of affecting additional paid-in-capital on the Consolidated Balance Sheet. These discrete income tax items should be classified along with other income tax cash flows as an operating activity on the Consolidated Statement of Cash Flows. In addition, cash paid by an employer when directly withholding shares for tax-withholding purposes should be classified as a financing activity. This guidance is effective for annual periods beginning after December 15, 2016 for public business entities. For private companies and emerging growth companies, this guidance is effective for annual periods beginning after December 15, 2017, and interim periods within annual periods beginning after December 15, 2018. Early adoption is permitted for all entities in any period. An entity that elects early adoption must adopt all amendments in the same period. Amendments requiring recognition of excess income tax benefits and income tax deficiencies in the Consolidated Statement of Operations should be applied prospectively. The Company early adopted this guidance on a prospective basis for the year ended December 31, 2017. At the date of adoption, there was an immaterial impact to the computation of diluted earnings per share, but no impact to the Company’s financial position or results of operations. In February 2018, the FASB issued new guidance to provide companies the option to reclassify income tax effects that are stranded in accumulated other comprehensive income as a result of income tax reform to retained earnings. This guidance is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted for reporting periods for which financial statements have not yet been issued or made available for issuance. In the period of adoption, an entity would be able to choose whether to apply the amendments retrospectively or in the period of adoption. The Company elected to early adopt this guidance on a prospective basis, resulting in a $2,717 reclassification of stranded income tax effects from accumulated other comprehensive income to retained earnings within the Equity section of the Consolidated Balance Sheet as of December 31, 2017. There was no impact to the Company’s financial position, results of operations, or cash flows. Not Yet Adopted In May 2014, the FASB issued guidance that establishes the manner in which an entity recognizes the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. While the guidance will replace most existing GAAP revenue recognition guidance, the scope of the guidance excludes insurance contracts. The Company has reviewed its sources of revenues, and has determined that no material revenues are derived from non-insurance contracts and thus subject to the new revenue recognition guidance. This guidance is effective for annual and interim reporting periods beginning after December 15, 2017 for public business entities. For private companies and emerging growth companies, this guidance is effective for annual reporting periods beginning after December 15, 2018 and interim periods within fiscal years beginning after December 15, 2019. Early adoption is permitted for all entities. We currently believe that this guidance will have no impact on our financial position, results of operations, or cash flows. In January 2016, the FASB issued amended guidance that generally requires entities to measure equity securities at fair value and recognize changes in fair value in their results of operations. The amended guidance also simplifies the impairment assessment of equity securities without readily determinable fair values by requiring entities to perform a qualitative assessment to identify impairment. The FASB issued other disclosure and presentation improvements related to financial instruments within the guidance. The amended guidance is effective for annual and interim reporting periods beginning after December 15, 2017 for public business entities. For private companies and emerging growth companies, this guidance is effective for annual reporting periods beginning after December 15, 2018 and interim periods within fiscal years beginning after December 15, 2019. Early adoption is permitted for all non-public entities as of the fiscal year beginning after December 15, 2017, including interim periods within those fiscal years. We are evaluating the requirements of this amended measurement and classification of financial instruments guidance and the potential impact on our financial position, results of operations, and cash flows. In February 2016, the FASB issued new guidance that requires lessees to recognize leases, including operating leases, on the lessee’s Consolidated Balance Sheet, unless a lease is considered a short-term lease. The new guidance also requires entities to make new judgments to identify leases. The new guidance, which replaces the current lease guidance, is effective for annual and interim reporting periods beginning after December 15, 2018 for public business entities. For private companies and emerging growth companies, this guidance is effective for annual reporting periods beginning after December 15, 2019 and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted for all entities. We do not expect the adoption of this new guidance to have a significant impact on our financial position, results of operations, or cash flows. In June 2016, the FASB issued a new standard that will require timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The guidance will require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better form their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. Organizations will continue to use judgment to determine which loss estimation method is appropriate for their circumstances. Additionally, the guidance requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. These disclosures include qualitative and quantitative requirements that provide additional information about the amounts recorded in the financial statements. Finally, the guidance amends the accounting for credit losses on available-for-sale fixed income securities and purchased financial assets with credit deterioration. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019 for public business entities which are SEC filers. For private companies and emerging growth companies, this guidance is effective for annual reporting periods beginning after December 15, 2020 and interim periods within fiscal years beginning after December 15, 2021. Early adoption is permitted for all entities as of the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are evaluating the impact this new guidance will have on our financial position, results of operations, and cash flows. In August and November 2016, the FASB issued amended guidance on the presentation and classification of various items in the Consolidated Statement of Cash Flows. The amendments address specific cash flow issues, including debt prepayments and contingent consideration payments made after a business combination. The amended guidance also requires the Consolidated Statement of Cash Flows to explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Currently, the Consolidated Statement of Cash Flows only explains the change in cash and cash equivalents. The amended guidance is effective for annual and interim reporting periods beginning after December 15, 2017 for public business entities. For private companies and emerging growth companies, this guidance is effective for annual reporting periods beginning after December 15, 2018 and interim periods within fiscal years beginning after December 15, 2019. Early adoption is permitted for all entities, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The amendments are to be applied using a retrospective transition method to each period presented. The adoption of this amended guidance will not have an impact on our financial position or results of operations. We do not expect this amended guidance to have a significant impact on our Consolidated Statement of Cash Flows. In March 2017, the FASB issued amended guidance to shorten the amortization period of premiums on certain purchased callable fixed income securities to the earliest call date. The amended guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. For private companies and emerging growth companies, this amended guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity should apply the amendments on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. We are evaluating the requirements of this guidance and the potential impact to our financial position, results of operations, and cash flows.

We frequently review our investment portfolio for declines in fair value. Our process for identifying declines in the fair value of investments that are other than temporary involves consideration of several factors. These factors include (i) the time period in which there has been a significant decline in value, (ii) an analysis of the liquidity, business prospects, and overall financial condition of the issuer, (iii) the significance of the decline, and (iv) our intent and ability to hold the investment for a sufficient period of time for the value to recover. When our analysis of the above factors results in the conclusion that declines in fair values are other than temporary, the cost of the securities is written down to fair value and the previously unrealized loss is therefore reflected as a realized capital loss on investment. The Company recorded no impairments during the three or six months ended June 30, 2018. The Company recorded impairments of $206 in the three and six months ended June 30, 2017. As of June 30, 2018, we held 296 fixed income securities with unrealized losses. As of December 31, 2017, we held 196 fixed income securities with unrealized losses. In conjunction with our outside investment advisors, we analyzed the credit ratings of the securities as well as the historical monthly amortized cost to fair value ratio of securities in an unrealized loss position. This analysis yielded no fixed income securities which had fair values less than 80% of amortized cost for the preceding 12-month period. Net investment income consisted of the following: Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 Fixed income securities $ 1,674 $ 1,580 $ 3,273 $ 2,911 Equity securities 243 93 472 163 Real estate 91 87 182 173 Cash and cash equivalents 43 34 62 44 Total gross investment income 2,051 1,794 3,989 3,291 Investment expenses 528 491 1,097 989 Net investment income $ 1,523 $ 1,303 $ 2,892 $ 2,302 Net realized capital gain on investments consisted of the following: Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 Gross realized gains $ 626 $ 552 $ 1,195 $ 1,180 Gross realized losses, excluding other-than-temporary impairment losses (376 ) (7 ) (476 ) (19 ) Other-than-temporary impairment losses — (206 ) — (206 ) Net realized capital gain on investments $ 250 $ 339 $ 719 $ 955

Investments, All Other Investments [Abstract]
Fair Value Measurements	7. Fair Value Measurements We maximize the use of observable inputs in our valuation techniques and apply unobservable inputs only to the extent that observable inputs are unavailable. The largest class of assets and liabilities carried at fair value by the Company at June 30, 2018 and December 31, 2017 were fixed income securities. Prices provided by independent pricing services and independent broker quotes can vary widely, even for the same security. Our available-for-sale investments are comprised of a variety of different securities, which are classified into levels based on the valuation technique and inputs used in their valuation. The valuation of cash equivalents and equity securities are generally based on Level I inputs, which use the market approach valuation technique. The valuation of fixed income securities generally incorporates significant Level II inputs using the market and income approach techniques. We may assign a lower level to inputs typically considered to be Level II based on our assessment of liquidity and relative level of uncertainty surrounding inputs. There were no assets or liabilities classified as Level III at June 30, 2018 or December 31, 2017. The following tables set forth our assets which are measured on a recurring basis by the level within the fair value hierarchy in which fair value measurements fall: June 30, 2018 Total Level I Level II Level III Fixed income securities: U.S. Government and agencies $ 15,287 $ — $ 15,287 $ — Obligations of states and political subdivisions 56,962 — 56,962 — Corporate securities 92,150 — 92,150 — Residential mortgage-backed securities 40,841 — 40,841 — Commercial mortgage-backed securities 14,582 — 14,582 — Asset-backed securities 21,765 — 21,765 — Total fixed income securities 241,587 — 241,587 — Equity securities: Basic materials 1,263 1,263 — — Communications 4,781 4,781 — — Consumer, cyclical 9,149 9,149 — — Consumer, non-cyclical 11,355 11,355 — — Energy 2,054 2,054 — — Financial 3,214 3,214 — — Industrial 8,410 8,410 — — Technology 9,579 9,579 — — Total equity securities 49,805 49,805 — — Cash and cash equivalents 30,955 30,955 — — Total assets at fair value $ 322,347 $ 80,760 $ 241,587 $ — December 31, 2017 Total Level I Level II Level III Fixed income securities: U.S. Government and agencies $ 9,649 $ — $ 9,649 $ — Obligations of states and political subdivisions 82,595 — 82,595 — Corporate securities 89,451 — 89,451 — Residential mortgage-backed securities 28,524 — 28,524 — Commercial mortgage-backed securities 11,170 — 11,170 — Asset-backed securities 15,369 — 15,369 — Total fixed income securities 236,758 — 236,758 — Equity securities: Basic materials 892 892 — — Communications 4,322 4,322 — — Consumer, cyclical 9,339 9,339 — — Consumer, non-cyclical 10,905 10,905 — — Energy 2,231 2,231 — — Financial 2,417 2,417 — — Industrial 9,205 9,205 — — Technology 8,250 8,250 — — Total equity securities 47,561 47,561 — — Cash and cash equivalents 27,594 27,594 — — Total assets at fair value $ 311,913 $ 75,155 $ 236,758 $ — There were no liabilities measured at fair value on a recurring basis at June 30, 2018 or December 31, 2017.

Reinsurance Disclosures [Abstract]
Reinsurance	8. Reinsurance The Company will assume and cede certain premiums and losses to and from various companies and associations under various reinsurance agreements. The Company seeks to limit the maximum net loss that can arise from large risks or risks in concentrated areas of exposure through use of these agreements, either on an automatic basis under general reinsurance contracts known as treaties or by negotiation on substantial individual risks. Reinsurance contracts do not relieve the Company from its obligation to policyholders. Additionally, failure of reinsurers to honor their obligations could result in significant losses to us. There can be no assurance that reinsurance will continue to be available to us at the same extent, and at the same cost, as it has in the past. The Company may choose in the future to reevaluate the use of reinsurance to increase or decrease the amounts of risk ceded to reinsurers. As a group at June 30, 2018, the Company retained the first $10,000 of weather-related losses from catastrophic events and had reinsurance under various reinsurance agreements up to $74,600 in excess of its $10,000 retained risk. These reinsurance risk limits are unchanged from 2017. The Company actively monitors and evaluates the financial condition of the reinsurers and develops estimates of the uncollectible amounts due from reinsurers. Such estimates are made based on periodic evaluation of balances due from reinsurers, judgments regarding reinsurers’ solvency, known disputes, reporting characteristics of the underlying reinsured business, historical experience, current economic conditions, and the state of reinsurer relations in general. Collection risk is mitigated from reinsurers by entering into reinsurance arrangements only with reinsurers that have strong credit ratings and statutory surplus above certain levels. The Company’s largest reinsurance recoverables on paid and unpaid losses were due from reinsurance companies with A.M. Best ratings of “A” or higher. A reconciliation of direct to net premiums on both a written and an earned basis is as follows: Three Months Ended June 30, 2018 Six Months Ended June 30, 2018 Premiums Written Premiums Earned Premiums Written Premiums Earned Direct premium $ 88,580 $ 53,987 $ 127,854 $ 91,179 Assumed premium 3,249 3,249 4,532 4,488 Ceded premium (6,559 ) (6,559 ) (8,878 ) (8,878 ) Net premiums $ 85,270 $ 50,677 $ 123,508 $ 86,789 Percentage of assumed earned premium to net earned premium 6.4 % 5.2 % Three Months Ended June 30, 2017 Six Months Ended June 30, 2017 Premiums Written Premiums Earned Premiums Written Premiums Earned Direct premium $ 83,671 $ 48,564 $ 120,051 $ 82,680 Assumed premium 3,396 3,368 4,591 4,539 Ceded premium (8,953 ) (6,279 ) (11,431 ) (8,757 ) Net premiums $ 78,114 $ 45,653 $ 113,211 $ 78,462 Percentage of assumed earned premium to net earned premium 7.4 % 5.8 % A reconciliation of direct to net losses and loss adjustment expenses is as follows: Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 Direct losses and loss adjustment expenses $ 41,121 $ 36,093 $ 59,758 $ 55,735 Assumed losses and loss adjustment expenses 487 2,024 1,076 2,613 Ceded losses and loss adjustment expenses (887 ) (1,887 ) (1,264 ) (4,397 ) Net losses and loss adjustment expenses $ 40,721 $ 36,230 $ 59,570 $ 53,951 If 100% of our ceded reinsurance was cancelled as of June 30, 2018 or December 31, 2017, no ceded commissions would need to be returned to the reinsurers. Reinsurance contracts are typically effective from January 1 through December 31 each year.

Related Party Transactions	12. Related Party Transactions We were organized by the NDFB to provide insurance protection for its members. We have a royalty agreement with the NDFB that recognizes the use of their trademark and provides royalties to the NDFB based on the premiums written on Nodak Insurance’s insurance policies. Royalties paid to the NDFB were $375 and $357 during the three months ended June 30, 2018 and 2017, respectively. Royalties paid to the NDFB were $682 and $651 during the six months ended June 30, 2018 and 2017, respectively. Royalty amounts payable of $166 and $99 were accrued as a liability to the NDFB at June 30, 2018 and December 31, 2017, respectively. State insurance laws require our insurance subsidiaries to maintain certain minimum capital and surplus amounts on a statutory basis. Our insurance subsidiaries are subject to regulations that restrict the payment of dividends from statutory surplus and may require prior approval from their domiciliary insurance regulatory authorities. Our insurance subsidiaries are also subject to risk-based capital (“RBC”) requirements that may further affect their ability to pay dividends. Our insurance subsidiaries statutory capital and surplus at December 31, 2017 exceeded the amount of statutory capital and surplus necessary to satisfy regulatory requirements, including the RBC requirements, by a significant margin. The amount available for payment of dividends from Nodak Insurance to NI Holdings after the conversion without the prior approval of the North Dakota Insurance Department is $15,654 based upon the policyholders’ surplus of Nodak Insurance at December 31, 2017. Prior to its payment of any extraordinary dividend, Nodak Insurance will be required to provide notice of the dividend to the North Dakota Insurance Department. This notice must be provided to the North Dakota Insurance Department 30 days prior to the payment of an extraordinary dividend and 10 days prior to the payment of an ordinary dividend. The North Dakota Insurance Department has the power to limit or prohibit dividend payments if Nodak Insurance is in violation of any law or regulation. These restrictions or any subsequently imposed restrictions may affect our future liquidity. No dividends were declared or paid by Nodak Insurance during the six months ended June 30, 2018 or the year ended December 31, 2017.

Compensation Related Costs [Abstract]
Benefit Plans	13. Benefit Plans The Company sponsors a profit-sharing plan that covers all eligible employees. Plan costs are funded annually as they are earned. The Company’s contribution expense for the profit-sharing plan totaled $138 and $157 during the three months ended June 30, 2018 and 2017, respectively, and totaled $592 and $526 during the six months ended June 30, 2018 and 2017, respectively. The Company also sponsors a 401(k) plan with an automatic contribution to all eligible employees and a matching contribution for eligible employees of 50% up to 3% of eligible compensation. The Company’s contributions expense to the 401(k) plan totaled $99 and $115 during the three months ended June 30, 2018 and 2017, respectively, and totaled $239 and $230 during the six months ended June 30, 2018 and 2017, respectively. All fees associated with both plans are deducted from the eligible employee accounts. Deferred Compensation Plan Effective April 28, 2016, the Board of Directors authorized a non-qualified deferred compensation plan covering key executives of the Company as designated by the Board of Directors. The Company’s policy is to fund the plan in a given calendar year by amounts that exceed the maximum contribution allowed by the Employee Retirement Income Security Act (“ERISA”), beginning in 2017. Funds deposited were $14 and $12 during the three months ended June 30, 2018 and 2017, respectively. Funds deposited were $158 and $117 during the six months ended June 30, 2018 and 2017, respectively. Employee Stock Ownership Plan The Company has established an Employee Stock Ownership Plan (the “ESOP”). The ESOP is intended to be an employee stock ownership plan within the meaning of Internal Revenue Code Section 4975(e)(7) and will invest primarily in common stock of the Company. In connection with our initial public offering in March 2017, Nodak Insurance loaned $2,400 to the ESOP’s related trust (the “ESOP Trust”). The ESOP loan will be for a period of ten years and bears interest at the long-term Applicable Federal Rate effective on the closing date of the offering (2.79% annually). The ESOP Trust used the proceeds of the loan to purchase shares in our initial public offering, which results in the ESOP Trust owning approximately 1.0% of the Company’s authorized shares. The ESOP has purchased the shares for investment and not for resale. The shares purchased by the ESOP Trust in the offering are held in a suspense account as collateral for the ESOP loan. The shares held in the ESOP’s suspense account are not considered outstanding for earnings per share purposes. Nodak Insurance will make semi-annual cash contributions to the ESOP in amounts no smaller than the amounts required for the ESOP Trust to make its loan payments to Nodak Insurance. While the ESOP makes two loan payments per year, a pre-determined portion of the shares will be released from the suspense account and allocated to participant accounts at the end of the calendar year. This release and allocation will occur on an annual basis over the ten-year term of the ESOP loan. Nodak Insurance will have a lien on the shares of common stock of the Company held by the ESOP to secure repayment of the loan from the ESOP to Nodak Insurance. If the ESOP is terminated as a result of a change in control of the Company, the ESOP may be required to pay the costs of terminating the plan. It is anticipated that the only assets held by the ESOP will be shares of the Company’s common stock. Participants in the ESOP cannot direct the investment of any assets allocated to their accounts. The initial ESOP participants are employees of Nodak Insurance. The employees of Primero will not participate in the ESOP. Each employee of Nodak Insurance will automatically become a participant in the ESOP if such employee is at least 21 years old, has completed a minimum of one thousand hours of service with Nodak Insurance, and has completed an Eligibility Computation Period. Employees are not permitted to make any contributions to the ESOP. Participants in the ESOP will receive annual reports from the Company showing the number of shares of common stock of the Company allocated to the participant’s account and the market value of those shares. The shares are allocated to participants based on compensation as provided for in the ESOP. In connection with the initial public offering, the Company created a contra-equity account on the Company’s Consolidated Balance Sheet equal to the ESOP’s basis in the shares. The basis of those shares was set at $10.00 per share as part of the initial public offering. As shares are released from the ESOP suspense account, the contra-equity account will be credited, which shall reduce the impact of the contra-equity account on the Company’s Consolidated Balance Sheet. The Company shall record a compensation expense related to the shares released, which compensation expense is equal to the number of shares released from the suspense account multiplied by the average market value of the Company’s stock during the period. The Company recognized compensation expense of $100 and $203 during the three and six months ended June 30, 2018, respectively. At December 31, 2017, 24,315 ESOP shares were released and allocated to participants, with a remainder of 215,685 ESOP shares in suspense at both December 31, 2017 and June 30, 2018. Using the Company’s quarter-end market price of $16.95 per share, the fair value of the unearned ESOP shares was $3,656 at June 30, 2018.

Stock Based Compensation	19. Stock Based Compensation At its 2017 Annual Shareholders’ Meeting, the NI Holdings, Inc. 2017 Stock and Incentive Plan (the “Plan”) was approved by shareholders. The purpose of the Plan is to promote the interests of the Company and its shareholders by aiding the Company in attracting and retaining employees, officers, consultants, advisors, and non-employee directors capable of assuring the future success of the Company, to offer such persons incentives to put forth maximum efforts for the success of the Company’s business, to compensate such persons through various stock and cash-based arrangements, and to provide them with opportunities for stock ownership in the Company, thereby aligning the interests of such persons with the Company’s shareholders. The Plan provides for the grant of nonqualified stock options, incentive stock options, restricted stock units (“RSUs”), stock appreciation rights, dividend equivalents, and performance share units (“PSUs”) to employees, officers, consultants, advisors, non-employee directors, and independent contractors designated by the Compensation Committee of the Board of Directors (the “Compensation Committee”). Awards made under the Plan are based upon, among other things, a participant’s level of responsibility and performance within the Company. The total aggregate number of shares of common stock that awards may be issued under all awards made under the Plan shall not exceed 500,000 shares of common stock, subject to adjustments as provided in the Plan. No eligible participant may be granted more than 100,000 shares from any stock options, stock appreciation rights, or performance awards denominated in shares, in the aggregate in any calendar year, subject to adjustment in accordance with the Plan. The aggregate amount payable pursuant to all performance awards denominated in cash to any eligible person in any calendar year is limited to $1,000 in value. Directors who are not also employees of the Company may not be granted awards denominated in shares that exceed $100 in any calendar year. Restricted Stock Units On December 1, 2017, the Compensation Committee awarded RSUs to non-employee directors and select executives. RSUs are promises to issue actual shares of common stock at the end of a vesting period. The RSUs granted to executives under the Plan were based on salary and generally vest 20% per year over a five-year period, while RSUs granted to non-employee directors vest in May 2018. Dividend equivalents on RSUs are accrued during the vesting period and paid in cash at the end of the vesting period, but are subject to forfeiture until the underlying shares become vested. Participants do not have voting rights with respect to RSUs. On March 1, 2018, the first tranche of executive RSUs vested. On March 1, 2018, the Compensation Committee awarded additional RSUs to select executives with the same terms as the previous awards. On May 22, 2018, the RSUs awarded to non-employee directors vested. Additional RSUs were awarded to non-employee directors to vest on the date of the next annual meeting of shareholders. The Company recognizes stock-based compensation costs based on the grant date fair value over the vesting period of the awards. Estimated forfeitures are included in the determination of compensation costs. No forfeitures are currently estimated. A summary of the Company’s outstanding RSUs for the six months ended June 30, 2018, is presented below: Shares Weighted- Fair Value Per Share Units outstanding at December 31, 2017 65,500 $ 17.31 Grants 40,000 16.25 Vested (26,200 ) 17.31 Units outstanding at June 30, 2018 79,300 $ 16.88 The following table shows the impact of RSU activity to the Company’s financial results: Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 RSU compensation expense $ 208 $ — $ 642 $ — Income tax benefit (44 ) — (135 ) — RSU compensation expense, net of income taxes $ 164 $ — $ 507 $ — Note: Share-based compensation was not available prior to the Company’s initial public offering in March 2017. At June 30, 2018, there was $1,021 of unrecognized compensation cost related to outstanding RSUs. That cost is expected to be recognized over a weighted-average period of 3.55 years. Performance Stock Units On March 1, 2018, the Compensation Committee awarded PSUs to select executives. PSUs are promises to issue actual shares of common stock at the end of a vesting period, if certain performance conditions are met. The PSUs granted to employees under the Plan were based on salary and include a three-year book value cumulative growth target with threshold and stretch goals. They will vest on the third anniversary of the grant date, subject to the participant’s continuous employment through the vesting date and the level of performance achieved. Dividend equivalents on PSUs are accrued and paid in cash at the end of the performance period in accordance with the level of performance achieved, but are subject to forfeiture until the underlying shares become vested. Participants do not have voting rights with respect to PSUs. The Company recognizes stock-based compensation costs based on the grant date fair value over the performance period of the awards. Estimated forfeitures are included in the determination of compensation costs. No forfeitures are currently estimated. The current cost estimate assumes that the cumulative growth target will be achieved. A summary of the Company’s outstanding PSUs for the six months ended June 30, 2018, is presented below: Performance Share Weighted-Average Fair Value Per Share Units outstanding at December 31, 2017 — $ — Grants (at target) 48,600 16.25 Units outstanding at June 30, 2018 48,600 $ 16.25 The following table shows the impact of PSU activity to the Company’s financial results: Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 PSU compensation expense $ 71 $ — $ 93 $ — Income tax benefit (15 ) — (20 ) — PSU compensation expense, net of income taxes $ 56 $ — $ 73 $ — Note: Share-based compensation was not available prior to the Company’s initial public offering in March 2017. The PSU grants above represent initial target awards and do not reflect potential increases or decreases resulting from financial performance objectives to be determined at the end of the performance period. The actual number of shares to be issued at the end of the performance period will range from 0% to 150% of the initial target awards. At June 30, 2018, there was $697 of unrecognized compensation cost related to outstanding PSUs. That cost is expected to be recognized over a weighted-average period of 2.50 years.

Earnings Per Share [Abstract]
Earnings Per Share	20. Earnings Per Share As described in Note 1, the conversion of the mutual company to a stock company resulted in the issuance of NI Holdings common shares on March 13, 2017. Earnings per share are computed by dividing net income available to common shareholders for the period by the weighted average number of common shares outstanding for the same period. The weighted average number of common shares outstanding was 22,377,421 and 22,369,632, respectively, during the three and six months ended June 30, 2018, and 22,663,280 and 22,711,373, respectively, during the three and six months ended June 30, 2017. For the period prior to the date of the conversion, we assumed that the net common shares issued in the initial public offering of 22,760,000 shares were outstanding since January 1, 2017. Unearned ESOP shares are not considered outstanding until they are released and allocated to plan participants. Unearned RSU and PSU shares are not considered outstanding until they are earned by award participants. The following table presents a reconciliation of the numerators and denominators we used in the basic and diluted per share computations for our common stock: Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 Basic earnings per common share: Numerator: Net income attributable to NI Holdings, Inc. $ 226 $ 129 $ 6,348 $ 4,818 Denominator: Weighted average shares outstanding 22,377,421 22,663,280 22,369,632 22,711,373 Basic earnings per common share $ 0.01 $ 0.01 $ 0.28 $ 0.21 Diluted earnings per common share: Numerator: Net income attributable to NI Holdings, Inc. $ 226 $ 129 $ 6,348 $ 4,818 Denominator: Number of shares used in basic computation 22,377,421 22,663,280 22,369,632 22,711,373 Weighted average effect of dilutive securities Add: Restricted stock units and performance share units 19,537 — 15,939 — Number of shares used in per share computations 22,396,958 22,663,280 22,385,571 22,711,373 Diluted earnings per common share $ 0.01 $ 0.01 $ 0.28 $ 0.21

loss as its primary measure. As a result, these fees are allocated to the non-standard auto segment (included in fee and other income) in the above tables. The remaining fee and other income amounts are not allocated to any segment. We do not assign or allocate all Consolidated Statement of Operations or Consolidated Balance Sheet line items to our operating segments. Those line items include investment income, net realized capital gain on investments, other income excluding non-standard auto insurance fees, and income taxes for the Consolidated Statement of Operations. For the Consolidated Balance Sheet, those items include cash and investments, property and equipment, other assets, accrued expenses, federal income taxes recoverable or payable, and equity.

Summary of Significant Accoun31

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2018
Accounting Policies [Abstract]
Use of Estimates	Use of Estimates: In preparing our consolidated financial statements, management makes estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the balance sheet and revenues and expenses for the periods then ended. Actual results could differ significantly from those estimates. We make estimates and assumptions that can have a significant effect on amounts and disclosures we report in our consolidated financial statements. The most significant estimates relate to our reserves for unpaid losses and loss adjustment expenses, earned premiums for crop insurance, valuation of investments, determination of other-than-temporary impairments, valuation allowances for deferred income tax assets, and deferred policy acquisition costs. While we believe our estimates are appropriate, the ultimate amounts may differ from the estimates provided. We regularly review our methods for making these estimates as well as the continuing appropriateness of the estimated amounts, and we reflect any adjustment we consider necessary in our current results of operations.
Variable-Interest Entities	Variable-Interest Entities: Any company deemed to be a variable interest entity (“VIE”) is required to be consolidated by the primary beneficiary of the VIE. We assess our investments in other entities at inception to determine if any meet the qualifications of a VIE. We consider an investment in another company to be a VIE if (a) the total equity investment at risk is not sufficient to permit the entity to finance its activities without additional subordinated financial support, (b) the characteristics of a controlling financial interest are missing (either the ability to make decisions through voting or other rights, the obligation to absorb expected losses of the entity or the right to receive the expected residual returns of the entity), or (c) the voting rights of the equity holders are not proportional to their obligations to absorb the expected losses of the entity and/or the rights to receive the expected residual returns of the entity, and substantially all of the entity’s activities either involve or are conducted on behalf of an investor that has disproportionately few voting rights. Upon the occurrence of certain events, we would reassess our initial determination of whether the investment is a VIE. We evaluate whether we are the primary beneficiary of each VIE and we consolidate the VIE if we have both (1) the power to direct the economically significant activities of the entity and (2) the obligation to absorb losses of, or the right to receive benefits from, the entity. We consider the contractual agreements that define the ownership structure, distribution of profits and losses, risks, responsibilities, indebtedness, voting rights, and board representation of the respective parties in determining whether we qualify as the primary beneficiary. Our assessment of whether we are the primary beneficiary of a VIE is performed at least annually. We control Battle Creek via a 100% quota-share reinsurance agreement between Nodak Insurance and Battle Creek, as well as the ability to control a majority of the Board of Directors of Battle Creek. Through the effects of the 100% quota-share agreement with Battle Creek, we are considered the primary beneficiary of Battle Creek’s operating results excluding investment income, bad debt expense, and income taxes. Therefore, we consolidate the financial statements of Battle Creek, and Battle Creek’s policyholders’ interest in Battle Creek is reflected as a non-controlling interest in Equity in our Consolidated Balance Sheet.
Cash and Cash Equivalents	Cash and Cash Equivalents: Cash and cash equivalents include certain investments in highly liquid debt instruments with original maturities of three months or less. Cost approximates fair value for these short-term investments.
Investments	Investments: We have categorized our investment portfolio as “available-for-sale” and have reported the portfolio at fair value, with unrealized gains and losses, net of income taxes, reported in accumulated other comprehensive income. Fair values are based on quoted market prices or dealer quotes, if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities. Amortization of premium and accretion of discount are computed using an effective interest method. Realized gains and losses are determined using the specific identification method and included in the determination of net income. Net investment income includes interest and dividend income together with amortization of purchase premiums and discounts, and is net of investment management and custody fees. We review our investments each quarter to determine whether a decline in fair value below the amortized cost basis is other than temporary. Accordingly, we assess whether we intend to sell or it is more likely than not that we will be required to sell a security before recovery of its amortized cost basis. For fixed income securities that are considered other-than-temporarily impaired and that we do not intend to sell and will not be required to sell prior to recovery of the amortized cost basis, we separate the amount of the impairment into the amount that is credit related (credit loss component) and the amount due to all other factors. The credit loss component is recognized in earnings and is the difference between the security’s amortized cost basis and the present value of its expected future cash flows discounted at the security’s effective yield. The remaining difference between the security’s fair value and the present value of future expected cash flows is due to factors that are not credit related and, therefore, is not required to be recognized as losses in the Consolidated Statement of Operations, but is recognized in other comprehensive income. We classify each fair value measurement at the appropriate level in the fair value hierarchy. The hierarchy gives the highest priority to unadjusted quoted market price in active markets for identical assets or liabilities (Level I measurements) and the lowest priority to unobservable inputs (Level III measurements). An asset’s or liability’s classification within the fair value hierarchy is based on the lowest level of significant input to its valuation. Level I – Quoted price in active markets for identical assets and liabilities. Level II – Quoted prices in markets that are not active or inputs that are observable either directly or indirectly. Level II inputs include quoted prices for similar assets or liabilities other than quoted in prices in Level I, quoted prices in markets that are not active, or other inputs that are observable or can be derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities. Level III – Unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities. Unobservable inputs reflect the reporting entity’s own assumptions that market participants would use in pricing the asset or liability. Level III assets and liabilities include financial instruments whose values are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.
Fair Value of Other Financial Instruments	Fair Value of Other Financial Instruments: Our other financial instruments, aside from investments, are cash and cash equivalents, premiums and agents’ balances receivable, and accrued expenses and accounts payable. The carrying amounts for cash and cash equivalents, premiums and agents’ balances receivable, and accrued expenses and accounts payable approximate their fair value based on their short-term nature. Other invested assets that do not have observable inputs and little or no market activity are carried on a cost basis. The carrying value of these other invested assets was $1,954 at June 30, 2018 and $1,972 at December 31, 2017.
Reclassifications	Reclassifications: Certain amounts in the 2017 consolidated financial statements have been reclassified to conform to the 2018 presentation. This includes a change in the Company’s reportable segments that was made in the fourth quarter of the year ended December 31, 2017. The prior segments were non-standard auto, crop, and other property and casualty. The new segments used throughout this report are private passenger auto, non-standard auto, home and farm, crop, and all other.
Revenue Recognition	Revenue Recognition: We record premiums written at policy inception and recognize them as revenue on a pro rata basis over the policy term or, in the case of crop insurance, over the period of risk. The portion of premiums that could be earned in the future is deferred and reported as unearned premiums. When policies lapse, the Company reverses the unearned portion of the written premium and removes the applicable unearned premium. Policy-related fee income is recognized when collected. The Company uses the direct write-off method for recognizing bad debts. Accounts are deemed to be delinquent after 60 days except for those accounts associated with amounts due from insureds for premiums, in which case policy cancellation procedures are commenced in accordance with state insurance regulations. Any earned but uncollected premiums are written off immediately upon the effective date of policy cancellation.
Policy Acquisition Costs	Policy Acquisition Costs: We defer our policy acquisition costs, consisting primarily of commissions, premium taxes and certain other underwriting costs, reduced by ceding commissions, which vary with and relate directly to the production of business. We amortize these deferred policy acquisition costs over the period in which we earn the premiums. The method we follow in computing deferred policy acquisition costs limits the amount of such deferred costs to their estimated realizable value, which gives effect to the premium to be earned, related investment income, losses and loss adjustment expenses, and certain other costs we expect to incur as we earn the premium.
Property and Equipment	Property and Equipment: We report property and equipment at cost less accumulated depreciation. Depreciation is computed using the straight-line method based upon the estimated useful lives of the assets.
Losses and Loss Adjustment Expenses	Losses and Loss Adjustment Expenses: Liabilities for unpaid losses and loss adjustment expenses are estimates at a given point in time of the amounts we expect to pay with respect to policyholder claims based on facts and circumstances then known. At the time of establishing our estimates, we recognize that our ultimate liability for losses and loss adjustment expenses will exceed or be less than such estimates. We base our estimates of liabilities for unpaid losses and loss adjustment expenses on assumptions as to future loss trends, expected claims severity, judicial theories of liability, and other factors. During the loss adjustment period, we may learn additional facts regarding certain claims, and, consequently, it often becomes necessary for us to refine and adjust our estimates of the liability. We reflect any adjustments to our liabilities for unpaid losses and loss adjustment expenses in our operating results in the period in which we determine the need for a change in the estimates. We maintain liabilities for unpaid losses and loss adjustment expenses with respect to both reported and unreported claims. We establish these liabilities for the purpose of covering the ultimate costs of settling all losses, including investigation and litigation costs. We base the amount of our liability for reported losses primarily upon a case-by-case evaluation of the type of risk involved, knowledge of the circumstances surrounding each claim, and the insurance policy provisions relating to the type of loss our policyholder incurred. We determine the amount of our liability for unreported losses and loss adjustment expenses on the basis of historical information by line of insurance. Inflation is not explicitly selected in the loss reserve analysis. However, historical inflation is embedded in the estimated loss reserving function through analysis of costs and trends and reviews of historical reserving results. We closely monitor our liabilities and update them periodically using new information on reported claims and a variety of statistical techniques. We do not discount our liabilities for unpaid losses and loss adjustment expense. Reserve estimates can change over time because of unexpected changes in assumptions related to our external environment and, to a lesser extent, assumptions as to our internal operations. Assumptions related to our external environment include the absence of significant changes in tort law and the legal environment which may impact liability exposure, the trends in judicial interpretations of insurance coverage and policy provisions, and the rate of loss cost inflation. Internal assumptions include consistency in the recording of premium and loss statistics, consistency in the recording of claims, payment and case reserving methodologies, accurate measurement of the impact of rate changes and changes in policy provisions, consistency in the quality and characteristics of business written within a given line of business, and consistency in reinsurance coverage and collectability of reinsured losses, among other items. To the extent we determine that underlying factors impacting our assumptions have changed, we attempt to make appropriate adjustments for such changes in our reserves. Accordingly, our ultimate liability for unpaid losses and loss adjustment expenses will likely differ from the amount recorded.
Income Taxes	Income Taxes: With the exception of Battle Creek, which files a stand-alone federal income tax return, we currently file a consolidated federal income tax return. For the year ended December 31, 2016, the consolidated federal income tax return included Nodak Mutual Insurance Company and its wholly-owned subsidiaries. For the year ended December 31, 2017 and thereafter, the consolidated federal income tax return included and will include thereafter NI Holdings and its wholly-owned subsidiaries. The Company reports tax-related interest and penalties, if any, as part of income tax expense in the year such amounts are determinable. We account for deferred income taxes using the asset and liability method. The objective of the asset and liability method is to establish deferred income tax assets and liabilities for the temporary differences between the financial reporting basis and the income tax basis of our assets and liabilities at enacted tax rates expected to be in effect when we realize or settle such amounts. Accounting guidance requires that companies re-measure existing deferred income tax assets (including loss carryforwards) and liabilities when a change in tax rate occurs, and record an offset for the net amount of the change as a component of income tax expense from continuing operations in the period of enactment. The guidance also requires any change to a previously recorded valuation allowance as a result of re-measuring existing temporary differences and loss carryforwards to be reflected as a component of income tax expense from continuing operations. The Company has elected to reclassify any tax effects stranded in accumulated other comprehensive income as a result of a change in income tax rates to retained earnings.
Credit Risk	Credit Risk: Our primary investment objective is to earn competitive returns by investing in a diversified portfolio of securities. Our portfolio of fixed income securities and, to a lesser extent, short-term investments, is subject to credit risk. We define this risk as the potential loss in fair value resulting from adverse changes in the borrower’s ability to repay the debt. We manage this risk by performing an analysis of prospective investments and through regular reviews of our portfolio by our investment staff and advisors. We also limit the amount of our total investment portfolio that we invest in any one security. Property and liability insurance coverages are marketed through captive agents in North Dakota and through independent insurance agencies located throughout all operating areas. All business is billed directly to policyholders. We maintain cash balances primarily at one bank, which are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250. During the normal course of business, balances are maintained above the FDIC insurance limit. The Company maintains short-term investment balances in investment grade money market accounts that are insured by the Securities Investor Protection Corporation (“SIPC”) up to $500. On occasion, balances for these accounts are maintained in excess of the SIPC insurance limit.
Reinsurance	Reinsurance: The Company limits the maximum net loss that can arise from large risks or risks in concentrated areas of exposure by reinsuring (ceding) certain levels of risks to other insurers or reinsurers, either on an automatic basis under general reinsurance contracts knows as “treaties” or by negotiation on substantial individual risks. Ceded reinsurance is treated as the risk and liability of the assuming companies. Reinsurance contracts do not relieve the Company from its obligations to policyholders. In the event that all or any of the reinsuring companies might be unable to meet their obligations under existing reinsurance agreements, the Company would be liable for such defaulted amounts.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets: Goodwill represents the excess of the purchase price over the underlying fair value of acquired entities. When completing acquisitions, we seek also to identify separately identifiable intangible assets that we have acquired. We assess goodwill and intangible assets with an indefinite useful life for impairment annually. We also assess goodwill and other intangible assets for impairment upon the occurrence of certain events. In making our assessment, we consider a number of factors including operating results, business plans, economic projections, anticipated future cash flows, and current market data. Inherent uncertainties exist with respect to these factors and to our judgment in applying them when we make our assessment. Impairment of goodwill and other intangible assets could result from changes in economic and operating conditions in future periods. We did not record any impairments of goodwill or other intangible assets during the three and six month periods ended June 30, 2018 and 2017. Goodwill arising from the acquisition of Primero in 2014 represents the excess of the purchase price over the fair value of the net assets acquired, and is reported separately in the Consolidated Balance Sheet. The purchase price in excess of the fair value of net assets acquired was negotiated at arms-length with an unrelated party and was based upon the strategic decision by Company management to expand both the geographic footprint and product lines of the Company. The nature of the business acquired was such that there were limited intangible assets not reflected in the net assets acquired. The purchase price was paid with a combination of cash and cancellation of obligations owed to the acquired company by the sellers. The goodwill which arose from this transaction is included in the basis of the net assets acquired and is not deductible for income tax purposes.
