Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The consolidated financial statements include accounts, after elimination of intercompany accounts and transactions, of Conifer Holdings, Inc. (the “Company” or “Conifer”), its wholly owned subsidiaries, Conifer Insurance Company ("CIC"), White Pine Insurance Company ("WPIC"), Red Cedar Insurance Company ("RCIC"), and Sycamore Insurance Agency, Inc ("SIA"). CIC, WPIC, and RCIC are collectively referred to as the "Insurance Company Subsidiaries." On a stand-alone basis, Conifer Holdings, Inc. is referred to as the "Parent Company." The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Company has applied the rules and regulations of the United States Securities and Exchange Commission (“SEC”) regarding interim financial reporting and therefore the consolidated financial statements do not include all of the information and notes required by GAAP for annual financial statements. In the opinion of Management, all adjustments, consisting of items of a normal recurring nature, necessary for a fair presentation of the consolidated interim financial statements, have been included. The results of operations for the three months ended March 31, 2018 , are not necessarily indicative of the results expected for the year ended December 31, 2018 . These consolidated financial statements and the notes thereto should be read in conjunction with the Company's audited consolidated financial statements and related notes included in its Annual Report on Form 10-K for the year ended December 31, 2017 , as filed with the SEC on March 15, 2018. Business The Company is engaged in the sale of property and casualty insurance products and has organized its business model around two classes of insurance businesses: commercial and personal lines. The Company underwrites a variety of specialty insurance products, including property, general liability, liquor liability, automobile, homeowners and dwelling policies. The Company markets and sells its insurance products through a network of independent retail agents and managing general agents. Policies are written in all 50 states. The Company’s corporate headquarters is located in Birmingham, Michigan with additional office facilities in Florida, Pennsylvania and Tennessee. The Company also generates other revenues through investment income and other income which mainly consists of installment fees and policy issuance fees generally related to the policies we write. We also generate equity earnings from SIA's 50% owned agency (the "Affiliate"). The Affiliate places small commercial risks mainly for alarm and security guard markets. Use of Estimates The preparation of financial statements in conformity with GAAP requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. While management believes the amounts included in the consolidated financial statements reflect Management's best estimates and assumptions, actual results may differ from these estimates. Recently Issued Accounting Guidance Effective January 1, 2018, the Company adopted FASB Accounting Standards Update ("ASU") No. 2016-01, Financial Instruments (Topic 825): Recognition and Measurement of Financial Assets and Financial Liabilities . As a result of adoption of this ASU, equity instruments that do not result in consolidation and are not accounted for under the equity method are measured at fair value and any changes in fair value are recognized in net income. Previously, the Company’s equity securities were classified as available-for-sale and changes in fair value were recorded in other comprehensive income. Upon adoption of this ASU, cumulative net unrealized gains on equity securities of $1.1 million , net of deferred income taxes of $0.5 million , were reclassified from accumulated other comprehensive income into accumulated deficit. Prior periods have not been recast to conform to the current presentation. See Note 2 ~ Investments for details regarding the change in net unrealized gains on equity securities included in net income for the quarter ended March 31, 2018 . Effective January 1, 2018, the Company early adopted ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The ASU provides an option to reclassify tax effects remaining in accumulated other comprehensive income as a result of the Tax Cuts and Jobs Act (TCJA) to retained earnings. Upon enactment of the TCJA, the U.S. corporate tax rate was reduced from 35% to 21% and the Company's U.S. deferred tax balances were remeasured to the lower enacted U.S. corporate tax rate. GAAP requires the effects of changes in tax rates and laws on deferred tax balances to be recorded as a component of income tax expense in the period of enactment, even if the assets and liabilities relate to items of accumulated other comprehensive income. As a result of adopting the ASU, the Company reclassified $77,000 of previously recognized deferred taxes from accumulated other comprehensive income into accumulated deficit as of January 1, 2018. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which addresses the financial reporting of leasing transactions. This update will require the recognition of a right-of-use asset and a corresponding lease liability, discounted to the present value, for all leases that extend beyond 12 months. For operating leases, the asset and liability will be expensed over the lease term on a straight-line basis, with all cash flows included in the operating section of the consolidated statement of cash flows. For finance leases, interest on the lease liability will be recognized separately from the amortization of the right-of-use asset in the consolidated statement of operations and the repayment of the principal portion of the lease liability will be classified as a financing activity while the interest component will be included in the operating section of the consolidated statement of cash flows. This ASU is effective for annual and interim reporting periods beginning after December 15, 2018. Early adoption is permitted. Management is currently evaluating the impact of the guidance. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326), which amends the current methodology and timing for recognizing credit losses. This amendment will replace the current GAAP "incurred loss" methodology for credit losses with a methodology based on expected credit losses. The new guidance will also require expanded consideration of a broader range of reasonable and increased supportable information for the credit loss estimates. This ASU is effective for annual and interim reporting periods beginning after December 15, 2019. Early adoption is permitted for years beginning after December 15, 2018. Management is currently evaluating the impact of the guidance.

Effective January 1, 2018, the Company adopted ASU No. 2016-01. As a result, equity securities are no longer classified as available-for-sale with unrealized gains and losses recognized in other comprehensive income; rather, all changes in fair value of equity securities are now recognized in net income. The change in fair value of equity securities included in net income for the quarter ended March 31, 2018 , was a $297 thousand loss, prior periods have not been recast for the adoption of this guidance.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company’s financial instruments include assets and liabilities carried at fair value, as well as assets and liabilities carried at cost or amortized cost but disclosed at fair value in these consolidated financial statements. Fair value is defined as the price that would be received for an asset or paid to transfer a liability in the principally most advantageous market for the asset or liability in an orderly transaction between market participants. In determining fair value, the Company applies the market approach, which uses prices and other relevant data based on market transactions involving identical or comparable assets and liabilities. The inputs to valuation techniques used to measure fair value are prioritized into a three-level hierarchy. The hierarchy gives the highest priority to quoted prices from sources independent of the reporting entity (“observable inputs”) and the lowest priority to prices determined by the reporting entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (“unobservable inputs”). The fair value hierarchy is as follows: Level 1 —Valuations that are based on quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 —Valuations that are based on observable inputs (other than Level 1 prices) such as quoted prices for similar assets or liabilities at the measurement date; quoted prices in markets that are not active; or other inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability. Level 3 —Unobservable inputs that are supported by little or no market activity. The unobservable inputs represent the Company’s best assumption of how market participants would price the assets or liabilities.

The Company uses unadjusted quoted prices for identical instruments to measure fair value. Level 1 also includes money market funds and other interest-bearing deposits at banks, which are reported as short-term investments. The fair value measurements that were based on Level 1 inputs comprise 5.2% of the fair value of the total investment portfolio as of March 31, 2018 . Level 2 investments include debt securities, which consist of U.S. government agency securities, state and local municipal bonds (including those held as restricted securities), corporate debt securities, mortgage-backed and asset-backed securities. The fair value of securities included in the Level 2 category were based on the market values obtained from a third party pricing service that were evaluated using pricing models that vary by asset class and incorporate available trade, bid and other observable market information. The third party pricing service monitors market indicators, as well as industry and economic events. The fair value measurements that were based on Level 2 inputs comprise 92.0% of the fair value of the total investment portfolio as of March 31, 2018 . The Company obtains pricing for each security from independent pricing services, investment managers or consultants to assist in determining fair value for its Level 2 investments. To validate that these quoted prices are reasonable estimates of fair value, the Company performs various quantitative and qualitative procedures, such as (i) evaluation of the underlying methodologies, (ii) analysis of recent sales activity, (iii) analytical review of our fair values against current market prices and (iv) comparison of the pricing services’ fair value to other pricing services’ fair value for the same investment. No markets for the investments were determined to be inactive at period-ends. Based on these procedures, the Company did not adjust the prices or quotes provided from independent pricing services, investment managers or consultants. As of March 31, 2018 , Level 3 is entirely comprised of the Company's subordinated debt. In determining the fair value of the subordinated debt outstanding at March 31, 2018 , the security attributes (issue date, maturity, coupon, calls, etc.) and market rates on September 29, 2017 (the date of issuance) were fed into a valuation model. A lognormal trinomial interest rate lattice was created within the model to compute the option adjusted spread (“OAS”) which is the amount, in basis points, of interest rate required to be paid under the debt agreement over the risk-free U.S. Treasury rates. The OAS was then fed back into the model along with the March 31, 2018 , U.S. Treasury rates. A new lattice was generated and the fair value was computed from the OAS. There were no changes in assumptions of credit risk from the issuance date. The Company’s policy on recognizing transfers between hierarchy levels is applied at the end of each reporting period. There were no transfers between Levels 1, 2 and 3 for the three months ended March 31, 2018 and 2017 , respectively.

Deferred Policy Acquisition Costs Disclosures [Abstract]
Deferred Policy Acquisition Costs	Deferred Policy Acquisition Costs The Company defers costs incurred which are incremental and directly related to the successful acquisition of new or renewal insurance business, net of corresponding amounts of ceded reinsurance commissions. Net deferred policy acquisition costs are amortized and charged to expense in proportion to premium earned over the estimated policy term. The Company anticipates that its deferred policy acquisition costs will be fully recoverable and there were no premium deficiencies for the three months ended March 31, 2018 and 2017 . The activity in deferred policy acquisition costs, net of reinsurance transactions, is as follows (dollars in thousands): Three Months Ended 2018 2017 Balance at beginning of period $ 12,781 $ 13,290 Deferred policy acquisition costs 5,782 6,138 Amortization of policy acquisition costs (6,513 ) (6,472 ) Net change (731 ) (334 ) Balance at end of period $ 12,050 $ 12,956

Unpaid Losses and Loss Adjustme

Insurance Loss Reserves [Abstract]
Unpaid Losses and Loss Adjustment Expenses	Unpaid Losses and Loss Adjustment Expenses The Company establishes reserves for unpaid losses and loss adjustment expenses ("LAE") which represent the estimated ultimate cost of all losses incurred that were both reported and unreported (i.e., incurred but not yet reported losses; or “IBNR”) and LAE incurred that remain unpaid at the balance sheet date. The Company’s reserving process takes into account known facts and interpretations of circumstances and factors including the Company’s experience with similar cases, actual claims paid, historical trends involving claim payment patterns and pending levels of unpaid claims, loss management programs, product mix and contractual terms, changes in law and regulation, judicial decisions, and economic conditions. In the normal course of business, the Company may also supplement its claims processes by utilizing third party adjusters, appraisers, engineers, inspectors, and other professionals and information sources to assess and settle catastrophe and non-catastrophe related claims. The effects of inflation are implicitly considered in the reserving process. Reserves are estimates of unpaid portions of losses that have occurred, including IBNR losses; therefore the establishment of appropriate reserves is an inherently uncertain and complex process. The ultimate cost of losses may vary materially from recorded amounts, which are based on management’s best estimates. The highest degree of uncertainty is associated with reserves for losses incurred in the current reporting period as it contains the greatest proportion of losses that have not been reported or settled. The Company regularly updates its reserve estimates as new information becomes available and as events unfold that may affect the resolution of unsettled claims. Changes in reserve estimates, which may be material, are reported in the results of operations in the period such changes are determined to be needed and recorded. Management believes that the reserve for losses and LAE, net of reinsurance recoverables, is appropriately established in the aggregate and adequate to cover the ultimate net cost of reported and unreported claims arising from losses which had occurred by the date of the consolidated financial statements based on available facts and in accordance with applicable laws and regulations. The table below provides the changes in the reserves for losses and LAE, net of reinsurance recoverables, for the periods indicated as follows (dollars in thousands): Three Months Ended 2018 2017 Gross reserves - beginning of period $ 87,896 $ 54,651 Less: reinsurance recoverables on unpaid losses 20,066 6,658 Net reserves - beginning of period 67,830 47,993 Add: incurred losses and LAE, net of reinsurance: Current period 13,344 12,654 Prior period (16 ) 3,079 Total net incurred losses and LAE 13,328 15,733 Deduct: loss and LAE payments, net of reinsurance: Current period 1,588 1,903 Prior period 12,711 8,813 Total net loss and LAE payments 14,299 10,716 Net reserves - end of period 66,859 53,010 Plus: reinsurance recoverables on unpaid losses 20,063 9,125 Less: deferred gain on ADC (1,431 ) — Gross reserves - end of period $ 85,491 $ 62,135 On September 28, 2017, the Company entered into an adverse development cover reinsurance agreement (the "ADC") to cover loss development of up to $17.5 million in excess of stated reserves as of June 30, 2017. The ADC provides up to $17.5 million of reinsurance for adverse net loss reserve development for accident years 2005 through 2016. The ADC attaches when net losses exceed $1.4 million of the $36.6 million carried reserves at June 30, 2017, and extends to $19.5 million in coverage up to $57.5 million . The Company retains a 10% co-participation for any development in excess of the retention. The Company accounts for the agreement as retroactive reinsurance. For the quarter ended March 31, 2018 , the Company recorded $1.7 million of net adverse loss development covered under this agreement, which increased the retroactive reinsurance recoverable to $8.9 million , leaving $8.6 million of coverage remaining on the ADC. The Company recorded the retroactive reinsurance recoverable in excess of the consideration as a deferred gain that is amortized to earnings using the interest method over the estimated claims settlement period. As of March 31, 2018 , the deferred gain of $1.4 million , net of amortization, is included in Other Liabilities on the consolidated balance sheets. The Company’s incurred losses during the three months ended March 31, 2018 , included favorable prior-year reserve development of $16,000 . Excluding the effect of the ADC, the commercial lines of business reported $104,000 of favorable prior-year development offset by $366,000 of unfavorable development from the personal lines of business of which $266,000 was attributable to additional 2017 losses from Hurricane Harvey. The ADC had a favorable impact of $278,000 on prior year reserve development. The Company’s incurred losses during the three months ended March 31, 2017, included prior-year adverse reserve development of $3.1 million . For the three months ended March 31, 2017, there was adverse development of $1.6 million from the commercial property line, $1.3 million from the commercial liability line of business, $325,000 from the Florida homeowners line, and $201,000 from the personal auto line of business. The adverse development was offset by $456,000 of favorable development in other lines of business for the same period.

Reinsurance Disclosures [Abstract]
Reinsurance	Reinsurance In the normal course of business, the Company seeks to minimize the loss that may arise from catastrophes or other events that cause unfavorable underwriting results by reinsuring certain levels of risk in various areas of exposure with reinsurers. The Company participates in reinsurance agreements in order to limit its loss exposure including protecting against catastrophe losses. The Company primarily ceded all specific commercial risks in excess of $500,000 in both 2018 and 2017 . Reinsurance does not discharge the direct insurer from liability to its policyholders. Failure of reinsurers to honor their obligations could result in losses to the Company. The Company evaluates the financial condition of its reinsurers and monitors the concentration of credit risk arising from similar geographic regions, activities, or economic characteristics of the reinsurers to minimize its exposure to significant losses from reinsurer insolvencies. To date, the Company has not experienced any significant difficulties in collecting reinsurance recoverables. The Company assumes written premiums under a few fronting arrangements, most of which are net of other reinsurance arrangements. The fronting arrangements are with unaffiliated insurers who write on behalf of the Company in markets that require a higher A.M. Best rating than the Company’s current rating, or where the policies are written in a state where the Company is not licensed or for other strategic reasons. The consideration for the ADC entered into in the third quarter of 2017 was a payment of $7.2 million , which resulted in a one-time charge to ceded premiums fully earned in the third quarter. There is a 35% contingent recovery depending on the performance of the reserves over time. No recovery is currently reflected in the financial statements. The following table presents the effects of such reinsurance and assumption transactions on premiums and losses and LAE (dollars in thousands). The 2018 ceded written and earned premium amounts include $367,000 of reinsurance reinstatement costs relating to Hurricane Irma. Three Months Ended 2018 2017 Written premiums: Direct $ 18,855 $ 20,900 Assumed 4,882 5,574 Ceded (3,892 ) (4,150 ) Net written premiums $ 19,845 $ 22,324 Earned premiums: Direct $ 21,224 $ 22,060 Assumed 6,500 6,204 Ceded (3,924 ) (4,124 ) Net earned premiums $ 23,800 $ 24,140 Losses and LAE: Direct $ 12,958 $ 16,033 Assumed 3,554 3,875 Ceded (3,184 ) (4,175 ) Net Losses and LAE $ 13,328 $ 15,733

Debt Disclosure [Abstract]
Debt	Debt On September 29, 2017, the Company executed $30.0 million in private placement subordinated notes (the "Notes"). The Notes have a maturity date of September 29, 2032, bear interest, payable quarterly at a fixed annual rate of 8.0% , and allow for up to four quarterly interest deferrals. On the fifth and tenth anniversary of the notes, the interest rate resets to 1,250 basis points and 1,500 basis points, respectively, above the 5 -year mid-swap rate. The Notes include an issuer call option at par from July 31, 2018, through October 31, 2018, and at 105% of par any time after September 29, 2020. The carrying value of the Notes is offset by $957,000 of debt issuance costs that will be amortized through interest expense over the life of the loan. The carrying value of the Notes was $29.0 million at March 31, 2018 and December 31, 2017 , respectively. The Notes replaced the Company's senior debt facility ("Credit Facility"), which was terminated upon execution of the Notes. The Credit Facility was comprised of three notes: a $17.5 million revolving line of credit ("Revolver") which commenced in October 2013; a $5.0 million five -year term note ("Term Note") which commenced in October 2013; and a $7.5 million five -year term note which commenced in September 2014 ("2014 Term Note"). The proceeds from the Notes were utilized, in part, to repay the outstanding balances on the Credit Facility, which were $16.4 million in total. The Notes contain various restrictive covenants that relate to the Company’s tangible net worth, fixed-charge coverage ratios, dividend paying capacity, reinsurance retentions, and risk-based capital ratios. At March 31, 2018 , the Company was in compliance with all of its subordinated debt financial covenants.

Stockholders' Equity Note [Abstract]
Shareholders' Equity	Shareholders’ Equity In September 2017, the Company issued $5.0 million of common equity through a private placement for 800,000 shares priced at $6.25 per share. The participants in the private placement consisted mainly of members of the Company’s management team and insiders, including Chairman and CEO James Petcoff. The Company used the proceeds to strengthen its balance sheet through contributions to the Insurance Company Subsidiaries to support their future growth, and to cover the cost of the ADC and reserve strengthening. On February 25, 2016, the Company's Board of Directors authorized a stock repurchase program, under which the Company may repurchase up to $2.1 million of its outstanding common stock. Under this program, Management was authorized to repurchase shares at prevailing market prices through open market purchases, privately negotiated transactions, block purchases or otherwise in accordance with applicable federal securities laws, including Rule 10b5-1 and 10b-18 of the Securities Exchange Act of 1934, as amended. The actual timing, number and value of shares repurchased under the program was determined by Management in its discretion and depends on a number of factors, including the market price of the Company’s stock, general market conditions, and other factors. For the three months ended March 31, 2018 and 2017 , the Company had not repurchased any shares of stock. Repurchased shares remain authorized but not issued or outstanding, and are available to be reissued in the future. As of March 31, 2018 and December 31, 2017 , the Company had 8,520,328 issued and outstanding shares of common stock, respectively. Holders of common stock are entitled to one vote per share and to receive dividends only when and if declared by the board of directors.

Commitments and Contingencies	Commitments and Contingencies Legal proceedings The Company and its subsidiaries are subject at times to various claims, lawsuits and proceedings relating principally to alleged errors or omissions in the placement of insurance, claims administration, and other business transactions arising in the ordinary course of business. Where appropriate, the Company vigorously defends such claims, lawsuits and proceedings. Some of these claims, lawsuits and proceedings seek damages, including consequential, exemplary or punitive damages, in amounts that could, if awarded, be significant. Most of the claims, lawsuits and proceedings arising in the ordinary course of business are related to the insurance policy issued. On the basis of current information, the Company does not believe that there is a reasonable possibility that any material loss exceeding amounts already accrued, if any, will result from any of the claims, lawsuits and proceedings to which the Company is subject, either individually, or in the aggregate.

Segment Reporting [Abstract]
Segment Information	Segment Information The Company is engaged in the sale of property and casualty insurance products and has organized its business model around two classes of insurance businesses: commercial and personal lines. Within these two insurance businesses, the Company offers various insurance products. Such insurance businesses are engaged in underwriting and marketing insurance coverages, and administering claims processing for such policies. The Company defines its operating segments as components of the business where separate financial information is available and used by the chief operating decision-making group in deciding how to allocate resources to its segments and in assessing its performance. In assessing performance of its operating segments, the Company’s chief operating decisionmaking group, comprised of key senior executives, reviews a number of financial measures including gross written premiums, net earned premiums and losses and LAE, net of reinsurance recoveries. The primary measure used for making decisions about resources to be allocated to an operating segment and assessing its performance is segment underwriting gain or loss which is defined as segment revenues, consisting of net earned premiums and other income, less segment expenses, consisting of losses and LAE, policy acquisition costs and operating expenses of the operating segments. Operating expenses primarily include compensation and related benefits for underwriting personnel, policy issuance and claims systems, rent and utilities. The Company markets, distributes and sells its insurance products through its own insurance agencies and a network of independent agents. All of the Company’s insurance activities are conducted in the United States with a concentration of activity in Florida, Michigan, Texas and Pennsylvania. For the three months ended March 31, 2018 and 2017 , gross written premiums attributable to these four states were 60% and 58% of the Company’s total gross written premiums. In addition to the reportable operating segments, the Company maintains a Corporate and Other category to reconcile segment results to the consolidated totals. The Corporate and Other category includes: (i) corporate operating expenses such as salaries and related benefits of the Company’s executive management team, and other corporate headquarters expenses, (ii) interest expense on the Company’s debt obligations; and (iii) all investment income activity. All investment income activity is reported within net investment income and net realized investment gains on the consolidated statements of operations. The Company’s assets on the consolidated balance sheet are not allocated to the reportable segments.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements include accounts, after elimination of intercompany accounts and transactions, of Conifer Holdings, Inc. (the “Company” or “Conifer”), its wholly owned subsidiaries, Conifer Insurance Company ("CIC"), White Pine Insurance Company ("WPIC"), Red Cedar Insurance Company ("RCIC"), and Sycamore Insurance Agency, Inc ("SIA"). CIC, WPIC, and RCIC are collectively referred to as the "Insurance Company Subsidiaries." On a stand-alone basis, Conifer Holdings, Inc. is referred to as the "Parent Company." The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Company has applied the rules and regulations of the United States Securities and Exchange Commission (“SEC”) regarding interim financial reporting and therefore the consolidated financial statements do not include all of the information and notes required by GAAP for annual financial statements. In the opinion of Management, all adjustments, consisting of items of a normal recurring nature, necessary for a fair presentation of the consolidated interim financial statements, have been included. The results of operations for the three months ended March 31, 2018 , are not necessarily indicative of the results expected for the year ended December 31, 2018 . These consolidated financial statements and the notes thereto should be read in conjunction with the Company's audited consolidated financial statements and related notes included in its Annual Report on Form 10-K for the year ended December 31, 2017 , as filed with the SEC on March 15, 2018.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. While management believes the amounts included in the consolidated financial statements reflect Management's best estimates and assumptions, actual results may differ from these estimates.
Recently Issued Accounting Guidance	Recently Issued Accounting Guidance Effective January 1, 2018, the Company adopted FASB Accounting Standards Update ("ASU") No. 2016-01, Financial Instruments (Topic 825): Recognition and Measurement of Financial Assets and Financial Liabilities . As a result of adoption of this ASU, equity instruments that do not result in consolidation and are not accounted for under the equity method are measured at fair value and any changes in fair value are recognized in net income. Previously, the Company’s equity securities were classified as available-for-sale and changes in fair value were recorded in other comprehensive income. Upon adoption of this ASU, cumulative net unrealized gains on equity securities of $1.1 million , net of deferred income taxes of $0.5 million , were reclassified from accumulated other comprehensive income into accumulated deficit. Prior periods have not been recast to conform to the current presentation. See Note 2 ~ Investments for details regarding the change in net unrealized gains on equity securities included in net income for the quarter ended March 31, 2018 . Effective January 1, 2018, the Company early adopted ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The ASU provides an option to reclassify tax effects remaining in accumulated other comprehensive income as a result of the Tax Cuts and Jobs Act (TCJA) to retained earnings. Upon enactment of the TCJA, the U.S. corporate tax rate was reduced from 35% to 21% and the Company's U.S. deferred tax balances were remeasured to the lower enacted U.S. corporate tax rate. GAAP requires the effects of changes in tax rates and laws on deferred tax balances to be recorded as a component of income tax expense in the period of enactment, even if the assets and liabilities relate to items of accumulated other comprehensive income. As a result of adopting the ASU, the Company reclassified $77,000 of previously recognized deferred taxes from accumulated other comprehensive income into accumulated deficit as of January 1, 2018. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which addresses the financial reporting of leasing transactions. This update will require the recognition of a right-of-use asset and a corresponding lease liability, discounted to the present value, for all leases that extend beyond 12 months. For operating leases, the asset and liability will be expensed over the lease term on a straight-line basis, with all cash flows included in the operating section of the consolidated statement of cash flows. For finance leases, interest on the lease liability will be recognized separately from the amortization of the right-of-use asset in the consolidated statement of operations and the repayment of the principal portion of the lease liability will be classified as a financing activity while the interest component will be included in the operating section of the consolidated statement of cash flows. This ASU is effective for annual and interim reporting periods beginning after December 15, 2018. Early adoption is permitted. Management is currently evaluating the impact of the guidance. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326), which amends the current methodology and timing for recognizing credit losses. This amendment will replace the current GAAP "incurred loss" methodology for credit losses with a methodology based on expected credit losses. The new guidance will also require expanded consideration of a broader range of reasonable and increased supportable information for the credit loss estimates. This ASU is effective for annual and interim reporting periods beginning after December 15, 2019. Early adoption is permitted for years beginning after December 15, 2018. Management is currently evaluating the impact of the guidance.
Fair Value Measurements	Level 1 investments consist of equity securities traded in an active exchange market. The Company uses unadjusted quoted prices for identical instruments to measure fair value. Level 1 also includes money market funds and other interest-bearing deposits at banks, which are reported as short-term investments. The fair value measurements that were based on Level 1 inputs comprise 5.2% of the fair value of the total investment portfolio as of March 31, 2018 . Level 2 investments include debt securities, which consist of U.S. government agency securities, state and local municipal bonds (including those held as restricted securities), corporate debt securities, mortgage-backed and asset-backed securities. The fair value of securities included in the Level 2 category were based on the market values obtained from a third party pricing service that were evaluated using pricing models that vary by asset class and incorporate available trade, bid and other observable market information. The third party pricing service monitors market indicators, as well as industry and economic events. The fair value measurements that were based on Level 2 inputs comprise 92.0% of the fair value of the total investment portfolio as of March 31, 2018 . The Company obtains pricing for each security from independent pricing services, investment managers or consultants to assist in determining fair value for its Level 2 investments. To validate that these quoted prices are reasonable estimates of fair value, the Company performs various quantitative and qualitative procedures, such as (i) evaluation of the underlying methodologies, (ii) analysis of recent sales activity, (iii) analytical review of our fair values against current market prices and (iv) comparison of the pricing services’ fair value to other pricing services’ fair value for the same investment. No markets for the investments were determined to be inactive at period-ends. Based on these procedures, the Company did not adjust the prices or quotes provided from independent pricing services, investment managers or consultants. As of March 31, 2018 , Level 3 is entirely comprised of the Company's subordinated debt. In determining the fair value of the subordinated debt outstanding at March 31, 2018 , the security attributes (issue date, maturity, coupon, calls, etc.) and market rates on September 29, 2017 (the date of issuance) were fed into a valuation model. A lognormal trinomial interest rate lattice was created within the model to compute the option adjusted spread (“OAS”) which is the amount, in basis points, of interest rate required to be paid under the debt agreement over the risk-free U.S. Treasury rates. The OAS was then fed back into the model along with the March 31, 2018 , U.S. Treasury rates. A new lattice was generated and the fair value was computed from the OAS. There were no changes in assumptions of credit risk from the issuance date. The Company’s policy on recognizing transfers between hierarchy levels is applied at the end of each reporting period. There were no transfers between Levels 1, 2 and 3 for the three months ended March 31, 2018 and 2017 , respectively. The Company’s financial instruments include assets and liabilities carried at fair value, as well as assets and liabilities carried at cost or amortized cost but disclosed at fair value in these consolidated financial statements. Fair value is defined as the price that would be received for an asset or paid to transfer a liability in the principally most advantageous market for the asset or liability in an orderly transaction between market participants. In determining fair value, the Company applies the market approach, which uses prices and other relevant data based on market transactions involving identical or comparable assets and liabilities. The inputs to valuation techniques used to measure fair value are prioritized into a three-level hierarchy. The hierarchy gives the highest priority to quoted prices from sources independent of the reporting entity (“observable inputs”) and the lowest priority to prices determined by the reporting entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (“unobservable inputs”). The fair value hierarchy is as follows: Level 1 —Valuations that are based on quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 —Valuations that are based on observable inputs (other than Level 1 prices) such as quoted prices for similar assets or liabilities at the measurement date; quoted prices in markets that are not active; or other inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability. Level 3 —Unobservable inputs that are supported by little or no market activity. The unobservable inputs represent the Company’s best assumption of how market participants would price the assets or liabilities.
