Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation, Nature of Business and Significant Accounting Policies and Practices	Note 1. Basis of Presentation, Nature of Business and Significant Accounting Policies and Practices Business Description Heritage Insurance Holdings, Inc. is an insurance holding company. Our insurance subsidiaries are Heritage Property & Casualty Insurance Company (“Heritage P&C”), Zephyr Insurance Company (“Zephyr”), Narragansett Bay Insurance Company (“NBIC”) and Pawtucket Insurance Company (“PIC”). PIC is currently inactive and has no policies in force or outstanding claims. Our other subsidiaries include: Heritage MGA, LLC (“MGA”), the managing general agent that manages substantially all aspects of our insurance subsidiaries’ business; Contractors’ Alliance Network, LLC, our vendor network manager; Skye Lane Properties, LLC, our property management subsidiary; First Access Insurance Group, LLC, our retail agency; Osprey Re Ltd., our reinsurance subsidiary that may provide a portion of the reinsurance protection purchased by our insurance subsidiaries; Heritage Insurance Claims, LLC, an inactive subsidiary reserved for future development; Zephyr Acquisition Company (“ZAC”); NBIC Holdings, Inc., NBIC Service Company which provides services to NBIC and Westwind Underwriters, Inc., an inactive subsidiary of NBIC Holdings, Inc. Our primary products are personal and commercial residential insurance, which we currently offer in Alabama, Connecticut, Florida, Georgia, Hawaii, Massachusetts, New Jersey, New York, North Carolina, Rhode Island, South Carolina, and Virginia. We conduct our operations under a single reporting segment. Basis of Presentation The consolidated financial statements include the accounts of Heritage Insurance Holdings, Inc. and its wholly-owned subsidiaries. The accompanying consolidated financial statements include the accounts of the Company and all other entities in which the Company has a controlling financial interest (none of which are variable interest entities). All intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates The preparation of consolidated financial statements in conformity with United States Generally Accepted Accounting Principles (“U.S. GAAP”) requires us to make estimates and assumptions about future events that affect the amounts reported in our consolidated financial statements and accompanying notes. We evaluate our estimates on an ongoing basis when updated information related to such estimates becomes available. We base our estimates on historical experience and information available to us at the time these estimates are made. Actual results could differ materially from these estimates. Cash and Cash Equivalents The Company’s cash and cash equivalents include demand deposits with financial institutions and short-term, highly-liquid financial instruments with original maturities of three months or less when purchased. The carrying amounts reported in the consolidated balance sheets for interest bearing deposits approximate their fair value because of the short maturity of these financial instruments. The Company excludes from cash and cash equivalents negative cash balances that the Company has with an individual financial institution. The liability presents outstanding checks not yet presented to the financial institution and is reported in accounts payable and other liabilities. Restricted Cash As of December 31, 2019, and 2018, restricted cash was $14.7 million and $12.3 million, respectively. For the years ended December 31, 2019 and 2018, Heritage P&C held approximately $9.0 million and $9.0 million relating to a reinsurance agreement with an entity that issued catastrophe (“CAT”) bonds, as Heritage P&C is contractually required to deposit certain installments of reinsurance premiums into a trust account and $5.7 million and $3.2 million in restricted cash relating to individual regulatory state deposits, respectively. The Company earned interest income of $28,969 and $36,532 on its restricted cash deposits. Investments The Company classifies all of its investments in debt securities as available-for-sale and reports them at fair value. Subsequent to its acquisition of debt securities available-for-sale, the Company records changes in value through the date of disposition as unrealized holding gains and losses, net of tax effects, and includes them as a component of other comprehensive income. Equity securities are recorded at fair value with changes in fair value reflected in net income and presented with realized gains and losses. The Company includes realized gains and losses, which it calculates using the specific-identification method for determining the cost of securities sold, in net income. The Company amortizes any premium or discount on fixed maturities over the remaining maturity period of the related securities using the effective interest method and reports the amortization in net investment income. The Company recognizes dividends and interest income when earned. Quarterly, the Company performs an assessment of its debt securities available-for-sale to determine if any are “other-than-temporarily” impaired. An investment is impaired when the fair value of the investment declines to an amount less than the cost or amortized cost of that investment. As part of the assessment process, the Company determines whether the impairment is temporary or “other-than-temporary”. The Company bases its assessment on both quantitative criteria and qualitative information, considering a number of factors including, but not limited to: how long the security has been impaired; the amount of the impairment; the Company intends to sell the investment or it is more likely than not that the Company will have to sell the investment before it recovers the amortized cost or cost; the financial condition and near-term prospects of the issuer; whether the issuer is current on contractually-obligated interest and principal payments; key corporate events pertaining to the issuer and whether the market decline was affected by macroeconomic conditions. If the Company were to determine that a debt security or participation in a commercial mortgage loan was impaired and the Company either intends to sell the investment or it is more likely than not that the Company will have to sell the investment before it is able to recover the amortized cost or cost, then the Company would record the full amount of the impairment in its consolidated statement of operations and other comprehensive income. A large portion of the Company’s investment portfolio consists of debt securities available-for-sale, which may be adversely affected by changes in interest rates as a result of governmental monetary policies, domestic and international economic and political conditions and other factors beyond its control. A rise in interest rates would decrease the net unrealized holding gains of our investment portfolio, offset by the Company’s ability to earn higher rates of return on funds reinvested. Conversely, a decline in interest rates would increase the net unrealized holding gains of our investment portfolio, offset by lower rates of return on funds reinvested. Accumulated other comprehensive income consists solely of unrealized gains and losses on debt securities available-for-sale, net of income tax. Fair Value Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants (an exit price). When reporting the fair values of the Company’s financial instruments, the Company prioritizes those fair value measurements into one of three levels based on the nature of the inputs, as follows: • Level 1—Assets and liabilities with values based on unadjusted quoted prices for identical assets or liabilities in an active market that the Company is able to access. • Level 2—Asset and liabilities with values based on quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets in markets that are not active; or valuation models with inputs that are observable, directly or indirectly for substantially the term of the asset or liability. • Level 3—certain inputs are unobservable (supported by little or no market activity) and significant to the fair value measurement. Unobservable inputs reflect the Company’s best estimate of what hypothetical market participants would use to determine a transaction price for the asset or liability at the reporting date based on the best information available in the circumstances. The Company estimates the fair value of its investments using the closing prices on the last business day of the reporting period, obtained from active markets such as the NYSE and NASDAQ. For securities for which quoted prices in active markets are unavailable, the Company uses observable inputs such as quoted prices in inactive markets, quoted prices in active markets for similar instruments, benchmark interest rates, broker quotes and other relevant inputs. The Company does not have any investments in its portfolio which require the use of unobservable inputs. The Company’s estimate of fair value reflects the interest rate environment that existed as of the close of business on December 31, 2019. Changes in interest rates after December 31, 2019 may affect the fair value of the Company’s investments. The Company believes the carrying amounts of its cash and cash equivalents, accounts receivable, accounts payable, accrued expenses, and other current liabilities approximate their fair values at December 31, 2019 and 2018, due to the immediate or short-term maturity of these instruments. The Company’s non-financial assets, such as goodwill and property, plant and equipment are carried at cost until there are indicators of impairment and are recorded at fair value only when an impairment charge is recognized. Long term debt is recorded at carrying value, see Note 14 – Long-Term Debt Premiums The Company records direct and assumed premiums written as revenue net of ceded amounts on a daily pro rata basis over the contract period of the related in force policies or reinsurance contract. For any portion of premiums not earned at the end of the reporting period, the Company records an unearned premium liability. Premiums receivable represents amounts due from our policyholders for billed premiums and related policy fees. We perform a policy-level evaluation to determine the extent to which the balance of premiums receivable exceeds the balance of unearned premiums. We then age any resulting exposure based on the last date the policy was billed to the policyholder, and we establish an allowance for credit losses for any amounts outstanding for more than 90 days. When we receive payments on amounts previously charged off, we reduce bad debt expense in the period we receive the payment. Balances in premiums receivable and the associated allowance account are removed upon cancellation of the policy due to non-payment. We recorded $290,300 allowance for the year ended December 31, 2019. We recorded no allowance for the years ended December 31, 2018 and 2017, respectively. Bad debt expense related to uncollectible premiums was $290,300, $0 and $0 for the years ended December 31, 2019, 2018 and 2017, respectively. When the Company receives premium payments from policyholders prior to the effective date of the related policy, the Company records an advance premiums liability. On the policy effective date, the Company reduces the advance premium liability and records the premiums as described above. Policy Acquisition Costs The Company incurs policy acquisition costs that vary with, and are directly related to, the production of new business. Policy acquisition costs consist of the following four items: (i) commissions paid to outside agents at the time of policy issuance; (ii) policy administration fees paid to a third-party administrator at the time of policy issuance; (iii) premium taxes; and (iv) inspection fees. The Company capitalizes policy acquisition costs to the extent recoverable, then the Company amortizes those costs over the contract period of the related policy. At each reporting date, the Company determines whether it has a premium deficiency. A premium deficiency would result if the sum of the Company’s expected losses, deferred policy acquisition costs, and policy maintenance costs (such as costs to store records and costs incurred to collect premiums and pay commissions) exceeded the Company’s related unearned premiums plus investment income. Should the Company determine that a premium deficiency exists, the Company would write off the unrecoverable portion of deferred policy acquisition cost. We earn ceding commission on its gross and net quota share reinsurance contracts. Our accounting policy is to allocate ceding commission between policy acquisition costs and general and administrative expenses for financial reporting purposes. Ceding commission is allocated between policy acquisition costs and general and administrative expenses based upon the proportion these costs bear to production of new business. For the years ended December 31, 2019 and 2018, we earned ceding commission income of $62.4 million and $73.0 million of which $47.0 million and $54.9 million was allocable to policy acquisition costs. Ceding commission income is deferred and recognized over the quota share contract period. The amount and rate of ceding reinsurance commissions earned on the net quota share contract can slide within a prescribed minimum and maximum, depending on loss performance and how future losses develop. Reinsurance The Company follows industry practice of reinsuring a portion of our risks. Reinsurance involves transferring, or “ceding”, all or a portion of the risk exposure on policies the Company writes to another insurer, known as a reinsurer. To the extent that the Company’s reinsurers are unable to meet the obligations they assume under the Company’s reinsurance agreements, the Company remains liable for the entire insured loss. The Company’s reinsurance agreements are generally short-term, prospective contracts. The Company records an asset, prepaid reinsurance premiums, and a liability, reinsurance payable, for the entire contract amount upon commencement of new reinsurance agreements. The Company amortizes its prepaid reinsurance premiums over the 12-month contract period. When the Company incurs losses recoverable under its reinsurance program, the Company records amounts recoverable from its reinsurers on paid losses plus an estimate of amounts recoverable on unpaid losses. The estimate of amounts recoverable on unpaid losses is a function of the Company’s liability for unpaid losses associated with the reinsured policies; therefore, the amount changes in conjunction with any changes to the estimate of unpaid losses. Given that an estimate of amounts recoverable from reinsurers on unpaid losses may change at any point in the future because of its relation to the Company’s reserves for unpaid losses, a reasonable possibility exists that an estimated recovery may change significantly from initial estimates. The Company estimates uncollectible amounts receivable from reinsurers based on an assessment of factors including the creditworthiness of the reinsurers and the adequacy of collateral obtained, where applicable. The Company recorded no uncollectible amounts under its reinsurance program or bad debt expense related to reinsurance for the years ended December 31, 2019, 2018 and 2017. The Company remains liable for claims payments if any reinsurer is unable to meet its obligations under the reinsurance agreements. 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 concentration of credit risk arising from similar geographic regions, activities or economics characteristics of the reinsurers to minimize its exposure to significant loses from reinsurers insolvencies. The Company contracts with several reinsurers to secure its annual reinsurance coverage, which the excess of loss treaties generally becomes effective June 1st each year. The Company purchases reinsurance each year taking into consideration probable maximum losses and reinsurance market condition. Long-Lived Assets—Property and Equipment Property and equipment is stated at cost less accumulated depreciation and amortization. Depreciation is calculated on a straight-line basis over the estimated useful lives as follows: building—40 years; computer hardware and software 3—years; office and furniture equipment—3 to 7 years. Leasehold improvements are amortized over the shorter of the lease term or the asset’s useful life. Expenditures for improvements are capitalized to the property accounts. Replacements and maintenance and repairs that do not improve or extend the life of the respective assets are expensed as incurred. Leases We lease office space under operating leases with expiration dates through 2023. We determine whether an arrangement constitutes a lease and record lease liabilities and right-of-use assets on our consolidated balance sheets at lease commencement. We primarily use our incremental borrowing rates for our operating leases (rates are not readily determinable) and implicit rates for our financing leases in determining the present value of lease payments. For short-term leases, we record rent expense in our consolidated statements of operations on a straight-line basis over the lease term and record variable lease payments as incurred. Business Acquisition The application of the purchase method of accounting for business combinations requires the use of significant estimates and assumptions in determining the fair value of assets acquired and liabilities assumed in order to properly allocate the fair value of the acquired business. The estimates of the fair value of the assets acquired and liabilities assumed are based upon assumptions believed to be reasonable using established valuation techniques that consider a number of factors and when appropriate, valuations performed by independent third-party appraisers. Assets acquired, and liabilities assumed in connection with business combinations are recorded based on their respective fair values at the date of acquisition. Goodwill and Intangible Assets Goodwill represents the excess of costs over the fair value of net assets acquired. Goodwill is subject to evaluation for impairment using a fair value-based test. This evaluation is performed annually, during the fourth quarter or more frequently if facts and circumstances warrant. The Company uses a qualitative approach to test goodwill for impairment by first assessing qualitative factors to determine whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. The Company applies this qualitative approach as of October 1 annually to any and all reporting units. If required following the qualitative assessment, the first step in the goodwill impairment test involves comparing the fair value of each of a reporting unit to the carrying value of a reporting unit. If the carrying value of a reporting unit exceeds the fair value of the reporting unit, the Company is required to proceed to the second step. In the second step, the fair value of the reporting unit would be allocated to the assets (including unrecognized intangibles) and liabilities of the reporting unit, with any residual representing the implied fair value of goodwill. An impairment loss would be recognized if, and to the extent that, the carrying value of goodwill exceeded the implied value. The Company reviews amortizable intangible assets for impairment whenever events or circumstances indicate that carrying amounts may not be recoverable. If the Company concludes that impairment exists, the carrying amount is reduced to fair value. No impairment was recognized in any period presented. Impairment of Long-Lived Assets Including Intangible Assets Subject to Amortization The Company assesses the recoverability of long-lived assets when events or circumstances indicate that the assets might have become impaired. The Company determines whether the assets can be recovered from undiscounted future cash flows and, if not recoverable, the Company recognizes impairment to reduce the carrying value to fair value. Recoverability of long-lived assets is dependent upon, among other things, the Company’s ability to maintain profitability, so as to be able to meet its obligations when they become due. No impairment was recognized in any period presented. Unpaid Losses and Loss Adjustment Expenses The Company’s reserves for unpaid losses and loss adjustment expenses represent the estimated ultimate cost of settling all reported claims plus all claims we incurred related to insured events that have occurred as of the reporting date, but that policyholders have not yet reported to the Company (incurred but not reported, or “IBNR”). The Company estimates its reserves for unpaid losses and loss adjustment expenses using individual case-based estimates for reported claims and actuarial estimates for IBNR losses. The Company continually reviews and adjusts its estimated losses as necessary based on industry development trends, the Company’s evolving claims experience and new information obtained. If the Company’s unpaid losses and loss adjustment expenses are considered to be deficient or redundant, the Company increases or decreases the liability in the period in which it identifies the difference and reflects the change in its current period results of operations. Though the Company’s estimate of the ultimate cost of settling all reported and unreported claims may change at any point in the future, a reasonable possibility exists that its estimate may vary significantly in the near term from the estimated amounts included in the Company’s consolidated financial statements. The Company reports its reserves for unpaid losses and loss adjustment expenses gross of the amounts related to unpaid losses recoverable from reinsurers and reports loss and loss adjustment expenses net of amounts ceded to reinsurers. The Company does not discount its loss reserves for financial statement purposes. Other revenue Our insurance affiliates may charge policyholders a policy fee on each policy written; to the extent these fees are not subject to refund, and the Company recognizes the income immediately when collected. The Company also charges pay-plan fees to policyholders that pay its premiums in more than one installment and records the fees as income when collected. Other income also includes rental income due under non-cancelable leases for space at the Company’s commercial property. Assessment Guaranty fund and other insurance-related assessments imposed upon the Company’s insurance company affiliates are recorded as policy acquisition costs in the period the regulatory agency imposes the assessment. To recover guaranty or other insurance-related assessments, the Company in turn submits a plan for recoupment to the Insurance Commissioner for approval and upon approval, begins collecting a policy surcharge that will allow it to collect the prior year’s assessments. There were no assessments during the periods presented. The Company collects other assessments imposed upon policyholders as a policy surcharge and records the amounts collected as a liability until the Company remits the amounts to the regulatory agency that imposed the assessment. Convertible Notes In August 2017 and September 2017, the Company issued collectively $136.8 million of 5.875% Convertible Senior Notes (the “Convertible Notes”) due August 1, 2037. The Convertible notes are accounted for in accordance with ASC 470-20. At the time of issuance and until December 1, 2017, the Company recorded the fair value of the derivatives on its balance sheet at fair value with changes in the values of these derivatives reflected in the consolidated statement of operations. As of December 31, 2019, the Company has $23.4 million of the Convertible Notes outstanding. Beginning December 1, 2017, the conversion option of the Convertibles Notes qualifies for the equity classification and will no longer be accounted for as a separate derivative instrument liability in accordance with applicable U.S. GAAP guidance. The Company separately accounts for the liability and equity components of Convertible Notes that can be settled in cash by allocating the proceeds from issuance between the liability component and the embedded conversion option, or equity component, in accordance with accounting for convertible debt instruments that may be settled in cash (including partial cash settlement) upon conversion. The value of the equity component is calculated by first measuring the fair value of the liability component, using the interest rate of a similar liability that does not have a conversion feature, as of the issuance date. The difference between the proceeds from the convertible debt issuance and the amount measured as the liability component is recorded as the equity component with a corresponding discount recorded on the debt. The Company recognizes the accretion of the resulting discount using the effective interest method as part of interest expense in its consolidated statements of operations. Debt Extinguishment The Company has reacquired convertible senior notes over a series of transactions. In accordance with ASC 470 “ Debt Debt Issuance and Discount Costs In connection with the issuance of debt, any debt issuance and discount costs are reflected on the balance sheet as an offset to long-term debt and amortized using the effective interest method over the life of the underlying debt instrument. Stock-Based Compensation The Company measures stock-based compensation at the grant date based on the fair value of the award and recognizes stock-based compensation expense over the requisite vesting period. Determining the fair value of stock option awards requires judgment, including estimating stock price volatility, forfeiture rates and expected option life. Restricted stock awards are valued based on the fair value of the stock on the grant date and the related compensation expense is recognized over the vesting period. Earnings Per Share The Company reports both basic earnings per share and diluted earnings per share. To calculate basic earnings per share, the Company divides net income attributable to common shareholders by the weighted-average number of shares outstanding during the period, including vested restricted shares. The Company calculates diluted earnings per share by dividing net income attributable to common shareholders by the weighted-average number of shares, and the effect of share equivalents, vested and unvested restricted shares and convertible notes outstanding during the period using the treasury stock method to calculate common stock equivalents. Income tax Income taxes are accounted for under the asset and liability method, that recognizes the amount of income taxes payable or refundable for the current year and recognizes deferred tax assets and liabilities based on the tax rates expected to be in effect during the periods in which the temporary differences reverse. Temporary differences arise when income or expenses are recognized in different periods in the consolidated financial statements than on the tax returns. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that all, or some portion, of the benefits related to deferred tax assets will not be realized. Income taxes includes both, estimated federal and state income taxes. Concentrations of Risk The Company’s current operations subject us to the following concentrations of risk: • Revenue—The Company writes residential property and liability policies exclusively. • Geographic—The Company writes its premium in coastal states in the southeastern and northeastern United States and Hawaii • Group concentration of credit risk—All of the Company’s reinsurers engage in similar activities and have similar economic characteristics that could cause their ability to repay us to be similarly affected by changes in economic or other conditions. • Credit risk—The Company chooses to deposit all its cash at twelve financial institutions. The Company mitigates its geographic and group concentrations of risk by entering into reinsurance contracts with highly rated, financially-stable reinsurers, and by securing irrevocable letters of credit from reinsurers when necessary. With regard to cash, the Company had $267.4 million and $244.6 million in excess of Federal Deposit Insurance Corporation (“FDIC”) insurance limits at December 31, 2019 and 2018, respectively. Deposits held in non- interest-bearing transaction accounts are combined with interest-bearing accounts and are insured up to $250,000. Reclassification Certain prior year amounts have been reclassified to conform to the current year presentation. Recently Adopted Accounting Pronouncements In February 2016, the FASB updated guidance on the accounting for leases that requires lessees to recognize a right-to-use asset and a lease liability for leases with terms of more than 12 months and retains the two classifications of a lease as either an operating or finance lease. The updated guidance was effective for reporting periods after December 31, 2018 and required that the earliest comparative period presented include the measurement and recognition of exiting leases with an adjustment to equity as if the updated guidance had always been applied. Alternatively, an entity may elect to recognize a cumulative effect adjustment to the opening balance of retained earnings in the year adopted. Early adoption was permitted. We adopted the guidance prospectively during the first quarter of 2019. As part of our adoption, we elected not to reassess historical lease classification or recognize short-term leases on our balance sheet. At implementation, we recorded approximately $2.5 million as right-of-use operating and financing We did not recognize an opening adjustment to retained earnings. Note 8 Accounting Pronouncements Not Yet Adopted The Company describes below recent pronouncements that may have a significant effect on its consolidated financial statements or on its disclosures upon future adoption. The Company does not discuss recent pronouncements that are not anticipated to have an impact on, or are unrelated to, its financial condition, results of operations, or related disclosures. In December 2019, The FASB issued ASU 2019-12— Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, Topic 740 . In November 2019, the FASB issued ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Financial Instruments-Credit Losses (Topic 326): Targeted Transition Relief Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments Financial Instruments-Overall Recognition and Measurement of Financial Assets and Financial Liabilities In August 2018, the FASB issued ASU 2018-12 , Financial Services – Insurance (Topic 944) Targeted Improvements to the Accounting for Long-Duration Contracts In March 2018, the FASB issued ASU 2018-04, Investments-Debt Securities (Topic 320) and Regulated Operations (Topic 980). Investments-Debt Securities Regulated Operations In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other FASB ASU 2016-13 Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments The updated guidance also amends the current other-than-temporary impairment model for available-for-sale debt securities by requiring the recognition of impairments relating to the credit losses through an allowance account and limits the amount of credit loss to the difference between a security’s amortized costs basis and its fair value. Any adjustments identified will be recorded in net realized and unrealized gains (losses) on the Company’s Consolidated Statement of Operations and Other Comprehensive Income. In addition, the Company will no longer use as a measurement the length of time a security has been in an unrealized loss position in determining i

Business Acquisitions	Note 2. Business Acquisitions Acquisition of NBIC On November 30, 2017, the Company completed the acquisition of all the outstanding capital stock of NBIC Holdings, Inc., the parent company of Narragansett Bay Insurance Company, a leading specialty underwriter of personal residential insurance products and services in several states in the northeastern United States for $250.0 million, including $210.0 million in cash, plus 2,222,215 shares of the Company’s common stock with an aggregate fair value of $40.0 million. The completion of the NBIC acquisition represents a significant advancement in executing the Company’s geographic diversification strategy by leveraging our combined platform to accelerate growth along the Eastern region. The transaction was accounted for using the acquisition method of accounting, which requires, assets acquired, and liability assumed be recognized at their fair values as of the acquisition date. The Company recognized goodwill of $106 million, attributable to expected growth and profitability, none of which is expected to be deductible for income tax purposes.

The Company does not intend to sell, nor is it likely that it would be required to sell, the fixed maturity securities before the Company recovers its amortized cost basis. Limited Partnerships, REIT’s and Limited Liability Company Investments The Company has interest in limited partnerships (LPs), Partnership Real Estate Investment Trust (REITs) and Limited Liability Companies (“LLCs”) totaling $6.4 million and $2.5 million at December 31, 2019 and 2018, respectively that are not registered or readily tradable on a securities exchange. The Company is not the primary beneficiary and does not consolidate these investments. These investments are carried at net asset value, which approximates fair value with changes in fair value recorded in net unrealized gains (losses) on the Company’s consolidated statement of income and comprehensive income. Realized gains (losses) on sales of these investments are reported within net realized and unrealized gains (losses) on the Company’s consolidated statement of income and comprehensive income. During 2019 the Company invested in a LP fund in the amount of $20.0 million. In November 2019, the Company was notified the Fund was terminating and in December received 95%, net of allocated costs of $275,900 of its total distribution. Upon completion of the funds audit the Company would receive the remaining 5% or $1.1 million. In January 2020, the Company received the $1.1 million representing the full holdback from the investment. The Company recorded the 5% hold back to other assets and the original unrealized gains from the fund in the amount of $1.1 million to realized gains, there was no change in the consolidated statement of operations and comprehensive income from this transaction. During the fourth quarter of 2019, Company invested in aggregate $4.0 million at $10 per share in a newly formed LP that conducts its business through an umbrella REIT. The REIT is a self-managed and self-administered company focusing on the purchase development and leasing of specialized agricultural, industrial and retail properties. The portfolio was 100% leased and had lease expirations through October 2029.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 6. Fair Value Measurements The Company performs fair value measurements in accordance with FASB Accounting Standards Codification (ASC) 820, Fair Value Measurement For the Company’s investments in U.S. government securities that do not have prices in active markets, agency securities, state and municipal governments, and corporate bonds, the Company obtains the fair values from its third-party valuation service and evaluates the relevant inputs, assumptions, methodologies and conclusions associated with such valuations. The valuation service calculates prices for the Company’s investments in the aforementioned security types on a month-end basis by using several matrix-pricing methodologies that incorporate inputs from various sources. The model the valuation service uses to price U.S. government securities and securities of states and municipalities incorporates inputs from active market makers and inter-dealer brokers. To price corporate bonds and agency securities, the valuation service calculates non-call yield spreads on all issuers, uses option-adjusted yield spreads to account for any early redemption features, then adds final spreads to the U.S. Treasury curve as of quarter end. The inputs the valuation service uses in their calculations are not quoted prices in active markets, but are observable inputs, and therefore represent Level 2 inputs. The following table presents information about the Company’s assets measured at fair value on a recurring basis. The Company assesses the levels for the investments at each measurement date, and transfers between levels are recognized on the actual date of the event or change in circumstances that caused the transfer in accordance with the Company’s accounting policy regarding the recognitions of transfers between levels of the fair value hierarchy. For the years ended December 31, 2019 and 2018, there were no transfers in or out of Level 1, 2, and 3. Investments excluded from the fair value hierarchy The Company also invests in LPs, REITs and LLCs. This investment categorization has the potential for higher returns but also the potential for higher degrees of risk, including less than stable rates of returns and may provide less liquidity. These investments are carried at net asset value, as reported by the managers of the funds, and are excluded from the fair value hierarchy. December 31, 2019 Total Level 1 Level 2 Level 3 Invested Assets: (in thousands) Debt Securities Available-for-sale U.S. government and agency securities $ 54,191 $ 366 $ 53,825 $ — States, municipalities and political subdivisions 76,355 — 76,355 — Special revenue 250,226 — 250,226 — Hybrid securities 101 — 101 — Industrial and miscellaneous 206,383 — 206,383 — Total debt securities 587,256 366 586,890 — Investment reported at NAV 7,993 — — — Total investments $ 595,249 $ 366 $ 586,890 $ — December 31, 2018 Total Level 1 Level 2 Level 3 Invested Assets: (in thousands) Debt Securities Available-for-sale U.S. government and agency securities $ 48,041 $ 354 $ 47,687 $ — States, municipalities and political subdivisions 59,289 — 59,289 — Special revenue 245,355 — 245,355 — Industrial and miscellaneous 152,457 — 152,457 — Redeemable preferred stock 4,507 4,507 — — Total debt securities 509,649 4,861 504,788 — Equity Securities Common stock 3,686 3,686 — — Non-redeemable preferred stock 12,770 12,770 — — Total equity securities 16,456 16,456 — — Investment reported at NAV 2,488 — — — Total investments $ 528,593 $ 21,317 $ 504,788 $ — Non-recurring fair value measurements Assets and liabilities that are measured at fair value on a non-recurring basis include intangible assets and goodwill which are recognized at fair value during the period in which an acquisition is completed, from updated estimates and assumptions during the measurement period, or when they are considered to be impaired. These non-recurring fair value measurements, primarily for intangible assets acquired, were based on Level 3 unobservable inputs. For the years ended December 31, 2019 and 2018, these non-recurring fair values inputs consisted of brand, agent relationships, renewal rights, customer relations, trade names, non-compete and goodwill. To evaluate such assets for a potential impairment, we determine the fair value of the goodwill and intangible assets using a combination of a discounted cash flow approach and market approaches, which contain significant unobservable inputs and therefore are considered a Level 3 fair value measurement. The unobservable inputs in the analysis generally include future cash flow projections and a discount rate. There were no non-recurring fair value adjustments to intangible assets and goodwill during 2019, 2018 and 2017. The measurement period may be up to one year from the acquisition date. We record any measurement period adjustments to the fair value of assets acquired and liabilities assumed, with the corresponding offset to goodwill.

Leases [Abstract]
Leases	Note 8. Leases The Company has entered into operating and financing leases primarily for real estate and vehicles. The Company will determine whether an arrangement is a lease at inception of the agreement. The operating leases have terms of one to ten years, and often include one or more options to renew. These renewal terms can extend the lease term from two to ten years and are included in the lease term when it is reasonably certain that the Company will exercise the option. The Company considers these options in determining the lease term used in establishing our right-of-use assets and lease obligations. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. Because the rate implicit in each operating lease is not readily determinable, the Company uses its incremental borrowing rate to determine present value of the lease payments. The Company used the implicit rates within the finance leases. The components of lease costs were as follows: For the Year Ended December 31, 2019 For the Year Ended December 31, 2018 Amortization of ROU assets - Finance leases $ 21 $ 79 Interest on lease liabilities - Finance leases 6 23 Variable lease cost (cost excluded from lease payments) 114 451 Operating lease cost (cost resulting from lease payments) 332 1,250 Total lease cost $ 473 $ 1,803 Supplemental balance sheet information related to leases was as follows: Balance Sheet Classification December 31, 2019 Right-of-use assets - operating Other assets $ 6,342 Right-of-use assets - finance Other assets $ 303 Lease Liability (1) Accounts payable and other liabilities $ (8,045 ) Lease Liability - finance Accounts payable and other liabilities $ (324 ) 1.

Deferred Reinsurance Ceding Commission The Company defers certain income in connection with its quota share treaties, the ceded reinsurance commissions income, called deferred reinsurance ceding commissions (“DRCC”), which are deferred and earned over the terms of the reinsurance agreements. Ceding commission on quota share agreements call for provisional ceding rate, subject sliding scale adjustments based on the loss experience of the reinsurers. Adjustments are reflected in current operations. The Company allocates 75% of total ceding commission income to policy acquisition costs and 25% of total ceding commission income to general and administrative expense. The Company defers reinsurance ceding commission income, which is amortized over the effective period of the related insurance policies.

Reinsurance

Insurance [Abstract]
Reinsurance	Note 1 2 . Reinsurance Our insurance regulators require all insurance companies, like us, to have a certain amount of capital and reinsurance coverage in order to cover losses and loss adjustment expenses upon the occurrence of a catastrophic event. Our reinsurance program provides reinsurance in excess of our state regulator requirements, which are based on the probable maximum loss that we would incur from an individual catastrophic event estimated to occur once in every 100 years based on our portfolio of insured risks. The nature, severity and location of the event giving rise to such a probable maximum loss differs for each insurer depending on the insurer’s portfolio of insured risks, including, among other things, the geographic concentration of insured value within such portfolio. As a result, a particular catastrophic event could be a one-in-100-year loss event for one insurance company while having a greater or lesser probability of occurrence for another insurance company. We also purchase reinsurance coverage to protect against the potential for multiple catastrophic events occurring in the same year. We share portions of our reinsurance program coverage among our insurance company affiliates. Significant Reinsurance Contracts 2019-2020 Reinsurance Programs Catastrophe Excess of Loss Reinsurance Effective June 1, 2019, we entered into catastrophe excess of loss reinsurance agreements covering Heritage Property & Casualty Insurance Company (“Heritage P&C”), Zephyr Insurance Company (“Zephyr”) and Narragansett Bay Insurance Company (“NBIC”). The catastrophe reinsurance programs are allocated amongst traditional reinsurers, catastrophe bonds issued by Citrus Re Ltd., a Bermuda special purpose insurer formed in 2014 (“Citrus Re”), the Florida Hurricane Catastrophe Fund (“FHCF”) and Osprey Re Ltd, our captive reinsurer. The FHCF covers Florida risks only and we participate at 90%. Our third-party reinsurers are either rated “A-” or higher by A.M. Best or S&P or are fully collateralized, to reduce credit risk. The reinsurance program, which is segmented into layers of coverage, protects the Company for excess property catastrophe losses and loss adjustment expenses. The 2019-2020 reinsurance program provides first event coverage up to $1.5 billion for Heritage P&C, first event coverage up to $708.0 million for Zephyr, and first event coverage up to $936.0 million for NBIC. Our first event retention for each insurance company subsidiary follows: Heritage P&C - $20.0 million; Zephyr - $20.0 million; NBIC – $13.8 million. Our program was placed on a cascading basis which provides greater horizontal protection in a multiple small events scenario and features additional coverage enhancements. This coverage exceeds the requirements established by the ratings agency of our insurance company affiliates, Demotech, Inc., the Florida Office of Insurance Regulation, the Hawaii Insurance Division, and the Rhode Island Department of Business Regulation. We are responsible for all losses and loss adjustment expenses in excess of our reinsurance program. For second or subsequent catastrophic events, our total available coverage depends on the magnitude of the first event, as we may have coverage remaining from layers that were not previously fully exhausted. An aggregate of $2.6 billion of limit purchased in 2019 includes reinstatement through the purchase of reinstatement premium protection. In total, we have purchased $2.6 billion of potential reinsurance coverage, including our retention, for multiple catastrophic events. Our ability to access this coverage, however, will be subject to the severity and frequency of such events. The Company's estimated net cost for the 2019-2020 catastrophe reinsurance programs is approximately $249.2 million. Gross Quota Share Reinsurance NBIC did not enter into a gross quota share reinsurance program for its fiscal year beginning June 1, 2019. For its previous fiscal year, NBIC purchased an 8% gross quota share reinsurance treaty effective June 1, 2018 which provided ground up loss recoveries of up to $1.0 billion. Net Quota Share Reinsurance NBIC’s Net Quota Share coverage is proportional reinsurance for which certain of our other reinsurance inures to the quota share (property catastrophe excess of loss and reinstatement premium protection and the second layer of the general excess of loss). An occurrence limit of $20.0 million for catastrophe losses is in effect on the quota share, subject to certain aggregate loss limits that vary by reinsurer. The amount and rate of reinsurance commissions slide, within a prescribed minimum and maximum, depending on loss performance. The Net Quota Share program was renewed on December 31, 2019 ceding 56% of the net premiums and losses and 5% of the prior year quota share will run off. Aggregate Coverage A $931.0 million of limit is structured on an aggregate basis (Top and Aggregate, Layer 1, Layer 2, Layer 3, Layer 4, Layer 5, Stub layers, Multi-Zonal and 2017-1 Notes). To the extent that this coverage is not fully exhausted in the first catastrophic event, it provides coverage commencing at its reduced retention for second and subsequent events where underlying coverage has been previously exhausted. The Company purchased reinstatement premium protection for $627.0 million of this coverage, which can be reinstated one time. Layers (with exception to FHCF) are “net” of a $40.0 million attachment point. Layers inure to the subsequent layers if the aggregate limit of the preceding layer(s) is exhausted, and the subsequent layer cascades down in its place. NBIC placed 42.5% of an aggregate contract, which covers all catastrophe losses excluding named storms, on December 1, 2019, expiring March 31, 2020. The limit on the contract is $20.0 million, with a retention of $20.0 million and franchise deductible of $1.0 million. NBIC placed 100% of an occurrence contract, which covers all catastrophe losses excluding named storms, on December 31, 2019, expiring December 31, 2020. The limit on the contract is $20.0 million with a retention of $20.0 million and has one reinstatement available. Per Risk Coverage For southeast losses and northeast commercial residential losses, excluding losses from named storms, the Company purchased property per risk coverage for losses and loss adjustment expenses in excess of $1.0 million per claim. The limit recovered for an individual loss is $9.0 million and total limit for all losses is $27.0 million. There are two reinstatements available with additional premium due based on the amount of the layer exhausted. For Northeast personal residential losses only, the Company purchased property per risk coverage for losses and loss adjustments expenses in excess of $750,000 per claim. The limit recovered for an individual loss is $250,000 and total limit for all losses is $750,000. There are two reinstatements available with additional premium due based on the amount of the layer exhausted. In addition, the Company purchased facultative reinsurance for losses in excess of $10.0 million for any properties it insured where the total insured value exceeded $10.0 million. This coverage applies to Southeast losses and Northeast commercial residential losses, excluding losses from named storms. General Excess of Loss NBIC’s general excess of loss reinsurance protects NBIC from single risk losses, both property and casualty. The casualty coverage provided by this reinsurance contract also responds on a “Clash” basis, meaning that multiple policies involved in a single loss occurrence can be aggregated into one loss and applied to the reinsurance contract. The coverage is in two layers in excess of NBIC’s retention of the first $400,000 of loss. The first layer is $350,000 excess $400,000 and the second layer is $2.75 million excess $750,000 (Casualty second layer is $1.25 million excess $750,000). Both layers are 100% placed. Semi-Automatic Facultative Excess of Loss NBIC’s automatic property facultative reinsurance protects NBIC from single risk losses, for property risks with a total insured value excess of $3.5 million subject to a limit of $3.75 million, subject to special acceptance. 2018 – 2019 Reinsurance Programs Catastrophe Excess of Loss Reinsurance Effective June 1, 2018, we entered into catastrophe excess of loss reinsurance agreements covering Heritage P&C, Zephyr and NBIC. The catastrophe reinsurance programs are allocated amongst traditional reinsurers, catastrophe bonds issued by Citrus Re and FHCF. The FHCF covers Florida risks only and we participate at 45%. Citrus Re, which provides fully collateralized multi-year coverage, covers catastrophe losses incurred by Heritage P&C only through the 2016 Class D and 2017-1 Notes, and covers catastrophe losses incurred by Heritage P&C, Zephyr and NBIC through the 2016 Class E Note. Our third-party reinsurers are either rated “A-” or higher by A.M. Best or S&P or are fully collateralized, to reduce credit risk. The reinsurance program, which is segmented into layers of coverage, protects the Company for excess property catastrophe losses and loss adjustment expenses. The 2018-2019 reinsurance program provides first event coverage up to $1.6 billion for Heritage P&C, first event coverage up to $801.0 million for Zephyr, and first event coverage up to $1.0 billion for NBIC. Our first event retention for each insurance company subsidiary follows: Heritage P&C - $20.0 million; Zephyr - $20.0 million; NBIC – $12.8 million. Our second and third event retentions for each insurance company subsidiary follows: Heritage P&C - $16.0 million; Zephyr - $16.0 million; NBIC – $8.8 million. Our program was placed on a cascading basis which provides greater horizontal protection in a multiple small events scenario and features additional coverage enhancements. This coverage exceeds the requirements established by the Companies’ rating agency, Demotech, Inc., the Florida Office of Insurance Regulation, the Hawaii Insurance Division, and the Rhode Island Department of Business Regulation. For the twelve months ending May 31, 2019, no single uncollateralized private reinsurer represented more than 10% of the overall limit purchased from our total reinsurance coverage. We are responsible for all losses and loss adjustment expenses in excess of our reinsurance program. For second or subsequent catastrophic events, our total available coverage depends on the magnitude of the first event, as we may have coverage remaining from layers that were not previously fully exhausted. An aggregate of $3.4 billion of limit purchased in 2018 includes reinstatement through the purchase of reinstatement premium protection. In total, we have purchased $3.5 billion of potential reinsurance coverage, including our retention, for multiple catastrophic events. Our ability to access this coverage, however, will be subject to the severity and frequency of such events. The Company's estimated net cost for the 2018-2019 catastrophe reinsurance programs is approximately $252.0 million. Gross Quota Share Reinsurance NBIC purchased an 8% gross quota share reinsurance treaty effective June 1, 2018 which provides ground up loss recoveries of up to $1.0 billion. Prior to this treaty, NBIC’s gross quota share treaty was 18.75%. Net Quota Share Reinsurance NBIC’s Net Quota Share coverage is proportional reinsurance for which certain of our other reinsurance inures to the quota share (property catastrophe excess of loss and reinstatement premium protection and the second layer of the general excess of loss). An occurrence limit of $20.0 million for catastrophe losses is in effect on the quota share, subject to certain aggregate loss limits that vary by reinsurer. The amount and rate of reinsurance commissions slide, within a prescribed minimum and maximum, depending on loss performance. NBIC ceded 49.5% of net premiums and losses during 2018 to the Net Quota Share and 8% of the 2017 Net Quota Share was in runoff. The Net Quota Share program was renewed on December 31, 2018 ceding 52% of the net premiums and losses and 10% of the prior year quota share will run off. Aggregate Coverage A $1.1 billion of limit is structured on an aggregate basis (Top and Aggregate, Layer 1, Layer 2, Layer 3, Layer 4, Stub layers, Multi-Zonal, 2017-1 Notes and 2016 Class E Notes). To the extent that this coverage is not fully exhausted in the first catastrophic event, it provides coverage commencing at its reduced retention for second and subsequent events where underlying coverage has been previously exhausted. The Company purchased reinstatement premium protection for $669.0 million of this coverage, which can be reinstated one time. Layers (with exception to FHCF and 2016 Class D Notes) are “net” of a $40.0 million attachment point. Layers inure to the subsequent layers if the aggregate limit of the preceding layer(s) is exhausted, and the subsequent layer cascades down in its place. NBIC placed 42.5% of an aggregate contract, which covers all catastrophe losses excluding named storms, on May 31, 2018, expiring December 31, 2018. The limit on the contract is $20.0 million, with a retention of $3.0 million and franchise deductible of $1.5 million. NBIC placed 92% of an occurrence contract, which covers all catastrophe losses excluding named storms, on May 31, 2018, expiring December 31, 2018. The limit on the contract is $20.0 million with a retention of $20.0 million. NBIC placed 40% of an aggregate contract, which covers all catastrophe losses excluding named storms, on December 31, 2018, expiring May 31, 2019. The limit on the contract is $20.0 million, with a retention of $20.0 million and franchise deductible of $1.0 million. NBIC placed 100% of an occurrence contract, which covers all catastrophe losses excluding named storms, on December 31, 2018, expiring December 31, 2019. The limit on the contract is $20.0 million with a retention of $20.0 million and has one reinstatement available. Per Risk Coverage For southeast losses and northeast commercial residential losses, excluding losses from named storms, the Company purchased property per risk coverage for losses and loss adjustment expenses in excess of $1.0 million per claim. The limit recovered for an individual loss is $9.0 million and total limit for all losses is $27.0 million. There are two reinstatements available with additional premium due based on the amount of the layer exhausted. In addition, the Company purchased facultative reinsurance in excess of $10.0 million for any properties it insured where the total insured value exceeded $10.0 million. This coverage applied to Southeast losses and Northeast commercial residential losses, excluding losses from name storms. General Excess of Loss NBIC’s general excess of loss reinsurance protects NBIC from single risk losses, both property and casualty. The casualty coverage provided by this contract also responds on a “Clash” basis, meaning that multiple policies involved in a single loss occurrence can be aggregated into one loss and applied to the reinsurance contract. The coverage is in two layers in excess of NBIC’s retention of the first $300,000 of loss. The first layer is $450,000 excess $300,000 and the second layer is $2.75 million excess $750,000 (Casualty second layer is $1.25 million excess $750,000). Both layers are 92% placed with the gross quota share providing the additional 8% coverage. Semi-Automatic Facultative Excess of Loss NBIC’s automatic property facultative reinsurance protects NBIC from single risk losses, for property risks with a total insured value excess of $3.5 million subject to a limit. 2017 – 2018 Reinsurance Programs Heritage P&C and Zephyr Program The Company placed its reinsurance program for the period from June 1, 2017 through May 31, 2018 during the second quarter of 2017. This reinsurance program incorporated the catastrophe risk of our two insurance subsidiaries, Heritage P&C, a Florida based insurer writing property insurance in multiple states, and Zephyr, a Hawaii based insurer. The programs are allocated amongst traditional reinsurers, catastrophe bonds issued by Citrus Re Ltd., a Bermuda special purpose insurer formed in 2014 (“Citrus Re”), and the Florida Hurricane Catastrophe Fund (“FHCF”). Coverage is specific to each insurer unless otherwise noted. The 2017-2018 reinsurance program provides, including retention, first event coverage up to $1.75 billion in Florida, first event coverage up to $731 million in Hawaii, and multiple event coverage up to $2.6 billion. This coverage exceeds the requirements established by the Company’s rating agency, Demotech, Inc., the Florida Office of Insurance Regulation, and the Hawaii Insurance Division. For the twelve months ending May 31, 2018, no single uncollateralized private reinsurer represented more than 10% of the overall limit purchased from our total reinsurance coverage. The reinsurance program, which was segmented into layers of coverage, protects the Company for excess property catastrophe losses and loss adjustment expenses. The Company’s 2017-2018 reinsurance program incorporates the mandatory coverage required by law to be placed with FHCF, which was available only for Florida catastrophe risk. For the 2017 hurricane season, the Company maintained the prior year selected participation percentage in the FHCF at 45%. The Company also purchased private reinsurance below and alongside the FHCF layer, as well as aggregate reinsurance coverage. The Company did not utilize its captive, Osprey, for any catastrophe risk for the 2017 hurricane season. The Company had a primary retention of the first $20 million of losses and loss adjustment expenses. Additionally, the December 1, 2016 treaty between Heritage P&C and Osprey was commuted effective June 1, 2017. Heritage P&C provided property insurance coverage for states other than Hawaii. The following describes the various layers of its June 1, 2017 to May 31, 2018 reinsurance program: • Heritage P&C’s Retention . If a first catastrophic event strikes a Heritage P&C risk, its primary retention is the first $20 million ($15 million plus $5 million co-participation on the Top and Aggregate layer described below) of losses and loss adjustment expenses. If a second catastrophic event strikes a Heritage P&C risk, its primary retention decreases to $16 million and the remainder of the losses are ceded to third parties. In a first event exceeding approximately $878 million, there was an additional co-participation of 20% subject to a maximum co-participation of $727,000. Assuming a 1-100yr 1 st st • Shared Layers . Immediately above the retention, the Company had purchased $372 million of reinsurance from third party reinsurers . This coverage included the following layers: Top and Aggregate layer, Underlying layer, Layer 1, Layer 2 and a private sliver alongside those layers. Through the payment of a reinstatement premium, Heritage P&C and Zephyr was able to reinstate $352 million of this reinsurance one time. There was $20 million of shared coverage subject to a seasonal aggregate of $68 million. • FHCF Layer • Layers alongside the FHCF. • 2017-2 Notes: • 2016 Class D and E Notes: • 2015 Class B and C Notes : During April 2015, Heritage P&C entered into catastrophe reinsurance agreements with Citrus Re. Layers above the FHCF - Florida program • 2017-1 Notes: • 2015 Class A Notes: • Multi-Zonal Layers. • Aggregate Coverage Zephyr provides property insurance coverage for Hawaii. The various layers of its 2017-2018 reinsurance program area as follows: • Zephyr’s Retention . If a first catastrophic event strikes Hawaii, Zephyr has a primary retention of the first $20 million ($15 million plus $5 million co-participation on the Top and Aggregate layer) of losses and loss adjustment expenses. If a second event strikes Hawaii, Zephyr’s primary retention decreases to $16 million and the remainder of losses are ceded to third parties. In a first event exceeding approximately $386 million, there is an additional co-participation of 3.8% subject to a maximum co-participation of $12 million. Assuming a 1-100-year event, a second event exceeding approximately $386 million results in an additional co-participation of 117.7%, subject to a maximum co-participation of $56 million. Zephyr has a $16 million primary retention for events beyond the second catastrophic event. • Shared Layers above retention . Immediately above the retention, the Company has purchased $372 million of reinsurance from third party reinsurers. This coverage includes the following layers: Top and Aggregate layer, Underlying layer, Layer 1, Layer 2 and a private sliver alongside those layers. Through the payment of a reinsurance reinstatement premium, Heritage P&C and Zephyr are able to reinstate $352 million of this reinsurance one time. There is $20 million of shared coverage subject to a seasonal aggregate of $68 million. • Multi-Zonal Layers. • Top Hawaii only layer. • Aggregate Coverage For a first catastrophic event striking Florida, our reinsurance program provided coverage up to $1.75 billion of losses and loss adjustment expenses, including our retention, and we are responsible for all losses and loss adjustment expenses in excess of such amount. For a first catastrophic event striking Hawaii, our reinsurance program provided coverage up to $731 million of losses and loss adjustment expenses, including our retention, and we are responsible for all losses and loss adjustment expenses in excess of such amount. For subsequent catastrophic events, our total available coverage depends on the magnitude of the first event, as we may have coverage remaining from layers that were not previously fully exhausted. An aggregate of $632 million of limit purchased in 2017 includes reinstatement through the purchase of reinsurance reinstated premium. In total, we have purchased $2.6 billion of potential reinsurance coverage, including our retention, for multiple catastrophic events. Our ability to access this coverage, however, will be subject to the severity and frequency of such events. Hurricane losses in states other than Hawaii would be covered under the Heritage P&C program with the exception of the FHCF coverage and the series 2015, 2016 and 2017 catastrophe bonds. Management deemed this reinsurance protection to be sufficient given the level of catastrophe exposure in 2017 for Alabama, Georgia, North Carolina and South Carolina. In placing our 2017-2018 reinsurance program, we sought to capitalize on favorable reinsurance pricing and mitigate uncertainty surrounding the future cost of our reinsurance by negotiating multi-year arrangements. The $687.5 million of aggregate coverage we have purchased from Citrus Re Ltd, which includes the 2015 Class A, B, and C notes, the 2016 Class D & E notes, and the 2017 Series notes extends $277.5 million of coverage until May 2018, $250 million of coverage for two-year period and $160 million of coverage for a three-year period. To the extent coverage was all or partially exhausted before the end of three years, it cannot be reinstated. In the aggregate, multi-year coverage from Citrus Re Ltd accounts for approximately 26% of our purchases of private reinsurance for the 2017 hurricane season. The terms of each of the multi-year coverage arrangements described above are subject to adjustment depending on, among other things, the size and composition of our portfolio of insured risks in future periods. Per Risk Coverage: The Company also purchased property per risk coverage for losses and loss adjustment expenses in excess of $1 million per claim. The limit recovered for an individual loss is $9 million and total limit for all losses is $27 million. There are two reinstatements available with additional premium due based on the amount of the layer exhausted. In addition, the Company purchased facultative reinsurance in excess of $10 million for any commercial properties it insured where the total insured value exceeded $10 million. NBIC Program NBIC, our insurance subsidiary located in Rhode Island, provides property insurance coverage in the states of Connecticut, Massachusetts, New Jersey, New York and Rhode Island. NBIC’s catastrophe reinsurance program provides coverage for loss occurrences up to $1 billion (1:100-year event) on the first event and includes automatic reinstatement protection. The program includes coverage for catastrophic events such as severe winter storms, hurricanes and tornadoes. During 2017, NBIC’s net retention for a catastrophic event of up to $1.0 billion is $1.3 million. NBIC’s reinsurance program also covers non-catastrophic losses. A summary of NBIC’s combined reinsurance protection follows. The reinsurance program is placed with strong participation from leading reinsurers across global markets with no one reinsurer exceeding 10%. The reinsurance partners are all rated A- to A+ by Standard and Poor’s. Property Catastrophe Excess of Loss NBIC’s property catastrophe program protects NBIC from the aggregation of losses in a single occurrence. Reinstatement provisions (one reinstatement at 100% of premium) on the first three layers and a portion of the fourth layer provides protection for NBIC from a second catastrophic event. The program is 81.25% placed, with the remaining 18.75% of catastrophe protection coming from NBIC’s gross quota share contract. NBIC’s net retention of $20 million is further reduced with a net quota share reinsurance contract described below. Reinstatement Premium Protection NBIC’s Reinstatement Premium Protection locks in the cost of a potential reinstatement premium charge that would occur should an event trigger catastrophe reinsurance. NBIC buys reinstatement premium protection for the first three layers and a portion of the fourth catastrophe excess of loss layers. Aggregate Contract For the year ended December 31, 2017, NBIC had 25% of an Aggregate contract, in two sections: • Section 1: $20 million excess $21.5 million in the aggregate for all catastrophe losses excluding named tropical storms. • Section 2: $12 million excess $8 million for named tropical storm losses. NBIC placed 25% of an aggregate contract on December 31, 2017, expiring May 31, 2018. The limit on the contract is $13.5 million, retention of $18.5 million and franchise deductible of $1.0 million. Gross Quota Share NBIC purchased an 18.75% gross account quota share reinsurance treaty which provides ground up loss recoveries of up to $1 billion. Net Lines Quota Share NBIC’s net lines quota share is proportional reinsurance for which certain of our other reinsurance inures to the quota share (property catastrophe excess of loss and reinstatement premium protection and the second layer of the general excess of loss.) An occurrence limit of $20 million for catastrophe losses is in effect on the quota share, subject to certain aggregate loss limits that vary by reinsurer. The amount and rate of reinsurance commissions slide, within a prescribed minimum and maximum, depending on loss performance. NBIC ceded 60% of net premiums and losses during 2017 to the Net Quota Share. The net quota share program was renewed on December 31, 2017 ceding 49.5% of the net premiums and losses and 8% of the prior year quota share will runoff. General Excess of Loss NBIC’s general excess of loss reinsurance protects NBIC from single risk losses, both property and casualty. The casualty coverage provided by this contract also responds on a “Clash” basis, meaning that multiple policies involved in a single loss occurrence can be aggregated into one loss and applied to the reinsurance contract. The coverage is in two layers in excess of NBIC’s retention of the first $300,000 of loss. The first layer is $450,000 excess $300,000 and the second layer is $2.75 million excess $750,000 (Casualty second layer is $1.25 million excess $750,000). Both layers are 81.25% placed with the gross quota share providing the additional 18.75% coverage. Semi-Automatic Facultative Excess of Loss NBIC’s automatic property facultative reinsurance protects NBIC from single risk losses, for property risks with a total insured value excess of $3.5 million subject to a limit of $2.5 million. Product specific reinsurance for Umbrella and Home Systems Protection NBIC’s umbrella facultative program protects NBIC’s Umbrella Liability business through the quota share reinsurance contract. NBIC has limits of liability of up to $1 million with 90% quota share, subject to an additional limit of liability of up to $4 million with 100% quota share. The home system protection (HSP) product is designed to protect customers from sudden and accidental mechanical breakdowns to furnaces, boilers, HVAC systems, home entertainment systems, pool heating and filtering equipment, and other mechanical systems that are not covered by standard homeowners’ insurance policies. The coverage is included in NBIC’s base policy and is 100% reinsured through Hartford Steam Boiler. Property Per Risk Coverage The Company also purchased property per risk coverage for losses and loss adjustment expenses in excess of $1 million per claim. The limit recovered for an individual loss is $9 million and total limit for all losses is $27 million. There are two reinstatements available with additional premium due based on the amount of the layer exhausted. In addition, the Company purchased facultative reinsurance in excess of $10 million for any commercial properties it insured that the total insured value exceeded $10 million. Effect of Reinsurance The Company’s reinsurance arrangements had the following effect on certain items in the Consolidated Statement of Income for the year ended December 31, 2019 and 2018: For the Year Ended December 31, 2019 Premiums Written Premiums Earned Losses and Loss Adjustment Expenses (in thousands) Direct $ 937,937 $ 924,247 $ 696,289 Ceded (436,564 ) (445,534 ) (423,001 ) Net $ 501,373 $ 478,713 $ 273,288 For the Year Ended December 31, 2018 Premiums Written Premiums Earned Losses and Loss Adjustment Expenses (in thousands) Direct $ 923,349 $ 926,326 $ 855,780 Ceded (477,451 ) (472,144 ) (618,355 ) Net $ 445,898 $ 454,182 $ 237,425

Reserve For Unpaid Losses

Reserve For Unpaid Losses	12 Months Ended

Insurance [Abstract]
Reserve for Unpaid Losses	Note 1 3 . Reserve For Unpaid Losses The Company determines the reserve for unpaid losses on an individual-case basis for all incidents reported. The liability also includes amounts which are commonly referred to as incurred but not reported, or “IBNR”, claims as of the balance sheet date. We estimate our IBNR reserves by projecting our ultimate losses using industry accepted actuarial methods and then deducting actual loss payments and case reserves from the projected ultimate losses. The table below summarizes the activity related to the Company’s reserve for unpaid losses: For the Year Ended December 31, 2019 2018 2017 (in thousands) Balance, beginning of period $ 432,359 $ 470,083 $ 140,137 Less: reinsurance recoverable on unpaid losses 250,507 315,353 589 Net balance, beginning of period 181,852 154,730 139,548 Incurred related to: Current year 276,985 224,080 188,914 Prior years (3,696 ) 13,345 12,567 Total incurred 273,289 237,425 201,481 Paid related to: Current year 137,764 104,368 114,344 Prior years 97,474 105,935 107,479 Total paid 235,238 210,303 221,823 Total unpaid claims assumed from acquisitions — — 35,524 Net balance, end of period 219,903 181,852 154,730 Plus: reinsurance recoverable on unpaid losses 393,630 250,507 315,353 Balance, end of period $ 613,533 $ 432,359 $ 470,083 The Company writes insurance in the coastal states of Alabama, Connecticut, Florida, Georgia, Hawaii, Massachusetts, New Jersey, New York, North Carolina, Rhode Island, South Carolina, and Virginia, which could be exposed to hurricanes or other natural catastrophes. Although the occurrence of a major catastrophe could have a significant effect on our monthly or quarterly results, such an event is unlikely to be so material as to disrupt our overall normal operations. However, the Company is unable to predict the frequency or severity of any such events that may occur in the near term or thereafter. The Company believes that the reserve for unpaid losses reasonably represents the amount necessary to pay all claims and related expenses which may arise from incidents that have occurred as of the balance sheet date. The reserve for unpaid losses is the estimate of amounts necessary to settle all reported and unreported incurred claims for the ultimate cost of insured losses, based upon the facts of each case and the Company’s experience with similar cases. Estimated amounts of salvage and subrogation are deducted from the reserve for claims and claims expense. The establishment of appropriate reserves, including reserves for catastrophe losses, is an inherently uncertain and complex process. Reserve estimates are primarily derived using an actuarial estimation process in which historical loss patterns are applied to actual paid losses and reported losses (paid losses plus individual case reserves established by claim adjusters) for an accident or report year to create an estimate of how losses are likely to develop over time. Development factors are calculated quarterly and periodically throughout the year for data elements such as claims reported and settled, paid losses, and paid losses combined with case reserves. The historical development patterns for these data elements are used as the assumptions to calculate reserve estimates, including the reserves for reported and unreported claims. Reserve estimates are regularly reviewed and updated, using the most current information available. Any resulting re-estimates are reflected in current results of operations. The Company’s losses incurred for the years ended December 31, 2019, 2018 and 2017 reflect prior year favorable development of $3.7 million and unfavorable development of $13.3 million and $12.6 million, respectively, associated with management’s best estimate of the actuarial loss and LAE reserves with consideration given to Company specific historical loss experience. While a portion of the 2018 development includes additional retention for hurricane losses, the majority of the 2018 loss development related to personal lines litigated and AOB claims from 2016 and 2017 accident years. Development in 2017 included $6.5 million for hurricane claims and strengthening of reserves for personal lines non-hurricane losses. The following is information about incurred and paid claims development as of December 31, 2019, net of reinsurance, as well as cumulative claim frequency and the total of incurred-but-not-reported liabilities plus expected development on reported claims included within the net incurred claims amounts.

Long-Term Debt

Long-Term Debt	12 Months Ended

Debt Disclosure [Abstract]
Long-Term Debt	Note 1 4 . Long-Term Debt Convertible Senior Notes In August 2017 and September 2017, the Company issued in aggregate $136.8 million of 5.875% Convertible Senior Notes (“Convertible Notes”) maturing on August 1, 2037, unless earlier repurchased, redeemed or converted. The Convertible Notes were issued in a private placement transaction pursuant to Rule 144A under the Securities Act, as amended. The Convertible Notes are senior unsecured obligations of the Company that will rank senior in right of payment to the Company’s future indebtedness that is expressly subordinated in right of payment to the Convertible Notes; equal in right of payment to the Company’s unsecured indebtedness that is not so subordinated; effectively junior to any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness or other liabilities by the Company’s subsidiaries other than the Guarantor, which will fully and unconditionally guarantee the Convertible Notes on a senior unsecured basis. Holders may convert their Convertible Notes at any time prior to the close of business on the business day immediately preceding February 1, 2037. On or after August 5, 2022 but prior to February 1, 2037, the Company may redeem for cash all or any portion of the Convertible Notes, at the Company’s option, at a redemption price equal to 100% of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest to , but excluding, the redemption date. Holders of the Convertible Notes will be able to cause the Company to repurchase their Convertible Notes for cash on any of August 1, 2022, August 1, 2027 and August 1, 2032, in each case at 100% of their principal amount, plus accrued unpaid interest to, but excluding, the relevant repurchase date. Interest accrues from August 16, 2017 and is payable semi-annually in arrears, on February 1 and August 1 of each year, beginning in 2018. At December 31, 2019, the Company had $21.3 million of the Convertible Notes outstanding, net of issuance and debt discount costs in aggregate of approximately, $2.1 million. For the year ended December 31, 2019, the Company made interest payments, net of affiliated Convertible Notes of approximately $1.5 million, on the outstanding Convertible Notes. As of December 31, 2018, the Company had $25.6 million of the Convertible Notes outstanding, net of debt issuance and debt discount costs which totaled approximately, $3.6 million. For the year ended December 31, 2018, the Company made interest payments of approximately $8.1 million on the Convertible Notes. During the fourth quarter of 2018, the Company exchanged Convertible Notes in the aggregate principal amount of $75.8 million for a combination of cash and the issuance of an aggregate of 3,595,452 shares of the Company’s common stock. Debt Extinguishment The Company has reacquired convertible senior notes over a series of transactions in 2019, 2018 and 2017. In accordance with ASC 470 “ Debt On February 19, 2019, the Company reacquired $5.8 million of its outstanding Convertible Notes, payment was made in cash of approximately $2.9 million and issuance of 285,201 shares of the Company’s common stock valued at $4.2 million. The repurchase resulted in a $48,000 non-operating loss. In October 2018, the Company reacquired $3.1 million of its outstanding Convertible Notes in the open market at a cost of $3.6 million. The repurchase resulted in a $73,000 non-operating loss. In December 2018, the Company repurchased in aggregate $72.7 million of its outstanding Convertible Notes. As consideration for the repurchase, the Company paid in cash $35.9 million and converted $53.0 million into 3,595,452 shares of the Company’s common stock. The Company recorded a $572,000 non-operating loss on the extinguishment and a reduction in debt discount liability of $6.2 million. In January 2019, in connection with the October 2018 settlement, the Company retired the repurchased $3.1 million Convertible Notes. In April 2018, the Company reacquired $10.6 million of its outstanding Convertible Notes in the open market at a cost of $13.4 million. The Company recognized a non-operating loss of $383,000 on extinguishment. In August 2018, in connection with the April 2018 settlement of the open market repurchase, the Company retired the repurchased $10.6 million Convertible Notes. The impact of the purchase of convertible notes during 2018 resulted in a net increase to additional paid-in capital from issuance of common stock on conversion of the Convertible Notes valued at $53.0 million reduced by the impact from the extinguishment of the allocated portion of the convertible option of $26.0 million. For 2019 and 2018 debt repurchases, the Company removed the respective net debt amount and the related portion of the derivative that was included in shareholders’ equity. The extinguishment of debt was measured at the then-current fair value at the time of purchase, with any difference recorded as a gain or loss on the extinguishment. In accordance with the purchase agreement governing the Company’s offer and sale of convertible debt, the Company or its affiliates are prohibited from reselling the notes once acquired. The repurchased Convertible Notes hold no registration rights. In December 2017, the conversion option of the Convertible Notes for equity classification no longer accounted for a separate derivative instruments’ liability in accordance with U.S. GAAP. The Company valued the embedded derivative and recorded additional paid-in-capital of $51.6 million. In connection with the change in the fair value, the Company recognized a fair value change in the year ended December 31, 2017 of $41.0 million as non-operating expenses in the consolidated statements of operations and comprehensive income (loss). On December 1, 2017, the Company held a Special Meeting of Stockholders, at which the Company’s stockholders approved, as required by Rule 312 of the New York Stock Exchange Listed Company Manual, the issuance of the Company’s common stock upon conversion of the Convertible Notes. Pursuant to the approval, the Company has the ability to settle the conversion option in shares of common stock, cash or a combination thereof. Upon conversion of the Convertible Notes, the Company intends to pay cash in respect of only the principal amount of the Convertible Notes being converted or (if lower) the conversion value thereof, and to settle any amounts in excess thereof in cash, shares of common stock or a combination thereof, at the Company’s election. In October and November 2017, the Company, through our subsidiary Heritage P&C, reacquired $21.1 million of its outstanding Convertible Notes in the open market at a cost of $25.2 million. The Company recognized a non-operating loss of $1.2 million on extinguishment. In connection with the repurchase, the Company removed the net debt of $17.7 million and liability derivative at the carrying amount of $6.2 million Mortgage Loan In October 2017, the Company and its subsidiary, Skye Lane Properties LLC, jointly obtained a commercial real estate mortgage loan in the amount of $12.7 million, bearing interest of 4.95% per annum and maturing on October 30, 2027. On October 30, 2022, the interest rate shall adjust to an interest rate equal to the annualized interest rate of the United States 5-year Treasury Notes as reported by Federal Reserve on a weekly average basis plus 3.10%. The Company makes monthly principal and interest payments against the loan. For each of the respective years ended December 31, 2019 and 2018, the Company made principal and interest payments of $892,850 on the mortgage loan. Senior Secured Credit Facility In December 2018, the Company entered into a five-year, $125.0 million credit agreement (the “Credit Agreement”) with a syndicate of lenders consisting of $75.0 million senior secured term loan facility (the “Term Loan Facility”) and a $50.0 million senior secured revolving credit facility (the “Revolving Credit Facility” and together with the Term Loan Facility, the “Credit Facilities”). Term Loan Facility: The principal amount of the Term Loan Facility amortizes in quarterly installments, beginning with the close of the fiscal quarter ending March 31, 2019, in an amount equal to $1.9 million per quarter, with the remaining balance payable at maturity. As of December 31, 2018, there was $75.0 million in aggregate principal outstanding on the Term Loan Facility. As of December 31, 2019, the balance of the term loan was $69.4 million. For the year ended December 31, 2019, the Company made interest payments of approximately $4.0 million on the term loan Revolving Credit Facility : The Revolving Credit Facility allows for borrowings of up to $50.0 million inclusive of a $5.0 million sublimit for the issuance of letters of credit and a $10.0 million sublimit for swingline loans. As of December 31, 2018, there was $20.0 million in aggregate principal outstanding under the Revolving Credit Facility. As of December 31, 2019, the Company had $10.0 million of borrowings and no letters of credit outstanding under the Revolving Credit Facility. For the year ended December 31, 2019, the Company made interest payments of $564,600 under the credit facility, respectively At December 31, 2019, the Company’s effective interest rate for the Term Loan Facility was 5.0625% and 5.0625% for the Revolving Credit Facility. The Company monitors the rates prior to the reset date which allows it to establish if the payment is monthly or quarterly payment based on the most beneficial rate used to calculate the interest payment. FHLB Loan Agreements In December 2018, a subsidiary of the Company received a fixed interest rate 3.094% cash loan of $19.2 million from the Federal Home Loan Bank (“FHLB”) Atlanta, with a maturity date of December 13, 2023. In connection with the agreement, the subsidiary became a member of FHLB. Membership in the FHLB required an investment in FHLB’s common stock which was purchased in December 2018 and valued at $1.4 million. Additionally, the transaction required securities be pledged as collateral. As of December 31, 2019, the fair value of the collateralized securities was $20.2 million and the equity investment in FHLB common stock was $1.4 million. As of December 31, 2019, the Company made quarterly interest payments of approximately $602,300 per the terms of the agreement.

The 2017 effective tax rate was affected by the valuation change for the conversion option liability (refer to Note 14 - Long Term Debt) The Tax Act was signed into law on December 22, 2017 and contains several key provisions that impact the Company's business, including the reduction of the U.S. federal corporate tax rate from 35% to 21% effective January 1, 2018, the reduction in the amount of executive compensation that could qualify as a tax deduction, and a change in how property and casualty taxpayers discount loss reserves. Under current accounting guidance, the effects of changes in tax rates and laws are recognized in the period in which the new legislation is enacted. However, due to the timing of the enactment of the Tax Act and its proximity to December 31, 2017, the SEC issued SAB 118 which provides a framework for companies to account for uncertainties in applying the provisions of the Tax Act. SAB 118 allows companies to record a provisional amount in situations where a company does not have the necessary information available but can make a reasonable estimate. In situations where companies cannot make a reasonable estimate due to various factors, including lack of information, a provisional amount is not recorded. Instead, companies will continue to apply current accounting guidance based on the provision of the tax laws that were in effect immediately prior to the Tax Act being enacted. The measurement period, as defined in SAB 118 for the Tax Act, begins on the enactment date of the Tax Act and ends when a company has obtained, prepared and analyzed the information that was needed in order to complete the accounting requirements under current accounting guidance. However, under no circumstances will the measurement period extend beyond one year from the enactment date of the Tax Act. The Company’s accounting for all elements of the Tax Act is now complete, consistent with the closing of the SAB 118 measurement period on December 22, 2018. As a result of guidance released by the IRS, namely Revenue Procedures 2019-06, the Company recorded the following adjustments to the accounting for the Tax Act during 2018: Property and Casualty Reserves: The Act changes the discount rate and payment patterns utilized to discount certain lines of business when computing the allowable tax reserve deduction. In July 2019, the IRS issued Revenue Procedure 2019-31 to finalize the revised unpaid loss discount factors. As a result of this additional guidance, the Company recorded an increase to its gross deferred tax asset for lo and an increase to its gross deferred tax liabilities for reserv during 2018. The recorded adjustment had no impact on the Company’s effective tax rate. The significant components of deferred tax assets and liabilities included in the consolidated balance sheets as December 31 were as follows: For the Year Ended December 31, 2019 2018 Deferred tax assets: (in thousands) Unearned premiums $ 12,585 $ 12,090 Unearned commission 8,671 10,733 Net operating loss — 109 Tax-related discount on loss reserve 2,716 2,329 Unrealized loss — 2,631 Stock-based compensation 297 297 Accrued expenses 757 2,321 Leases 331 — Other 1,890 1,443 Total deferred tax asset 27,247 31,953 Deferred tax liabilities: Deferred acquisition costs 17,871 17,494 Prepaid expenses 153 112 Unrealized gain 2,195 — Property and equipment 1,029 664 Note discount 478 710 Basis in purchased investments 100 163 Basis in purchased intangibles 16,977 18,982 Other 1,067 1,533 Total deferred tax liabilities 39,870 39,658 Net deferred tax liability $ (12,623 ) $ (7,705 ) As of December 31, 2019, the Company has net operating loss carryforwards for federal and state income tax purposes of $450,000 and $0, respectively. The losses will expire in 2031. In addition, the Company had a $400,000 capital loss carryforward which will expire in 2023. In assessing the net carrying The statute of limitations related to our federal and state income tax returns remains open from our filings for 2016 through 2018. For the 2014 tax year, the federal income tax return was examined by the tax authority resulting in no material adjustments. In April 2019, the Company was notified by the tax authority that the federal income tax returns for the years 2015, 2016 and 2017 will be examined. The Company does not believe the examination will have an adverse impact on our consolidated financial statements. Our reinsurance affiliate, Osprey Re, Ltd., which is based in Bermuda, made an irrevocable election under section 953(d) of the U.S. Internal Revenue Code of 1986, as amended, to be treated as a domestic insurance company for U.S. Federal income tax purposes. As a result of this election, our reinsurance subsidiary is subject to United States income tax as if it were a U.S. corporation. As of December 31, 2019, the Company had no uncertain tax positions or unrecognized tax benefits that, if recognized, would impact the effective income tax rate.

Statutory Accounting and Regula

Statutory Accounting and Regulations	12 Months Ended

Insurance [Abstract]
Statutory Accounting and Regulations	Note 1 6 . Statutory Accounting and Regulations State laws and regulations, as well as national regulatory agency requirements, govern the operations of all insurers such as our insurance subsidiaries. The various laws and regulations require that insurers maintain minimum amounts of statutory surplus and risk-based capital; restrict insurers’ ability to pay dividends; restrict the allowable investment types and investment mixes and subject the Company’s insurers to assessments. The Company’s insurance subsidiaries are required to file with state insurance regulatory authorities an “Annual Statement” which reports, among other items, net income and surplus as regards policyholders, which is called stockholder’s equity under GAAP. Combined results of the Company’s insurance subsidiaries reported statutory net loss of $16.3 million and $64.5 for the years ended December 31, 2019 and 2018, respectively. The Company’s insurance subsidiaries must maintain capital and surplus ratios or balances as determined by the regulatory authority of the states in which they are domiciled. Heritage P&C is required to maintain capital and surplus equal to the greater of $15 million or 10% of their respective liabilities. Zephyr is required to maintain a deposit of $750,000 in a federally insured financial institution. NBIC is required to maintain capital and surplus of $3.0 million. The combined statutory surplus for Heritage P&C, NBIC, and Zephyr was $351.8 million at December 31, 2019. The combined statutory surplus for Heritage P&C, NBIC, and Zephyr was $375.1 million at December 31, 2018. State laws also require the Company’s insurance subsidiaries to adhere to prescribed premium-to-capital surplus ratios, with which the Company’s insurance affiliates are complying. At December 31, 2019, our insurance subsidiaries met the financial and regulatory requirements of the states in which they do business. The legislatures of the states of domicile of our insurance affiliates have adopted the National Association of Insurance Commissioners (“NAIC”) recommendations with regard to expansion of the regulation of insurers to include non-insurance entity affiliates. Specifically, the new law permits the state insurance regulators to examine affiliated entities within an insurance holding company system in order to ascertain the financial condition of the insurer. The law also provides for certain disclosures regarding enterprise risk, which are satisfied by the provision of related information filed with the SEC. The NAIC published risk-based capital guidelines for insurance companies that are designed to assess capital adequacy and to raise the level of protection that statutory surplus provides for policy holders. Most states, including Florida, Hawaii, and Rhode Island, have enacted the NAIC guidelines as statutory requirements, and insurers having less statutory surplus than required will be subject to varying degrees of regulatory action, depending on the level of capital inadequacy. State insurance regulatory authorities could require an insurer to cease operations in the event the insurer fails to maintain the required statutory capital. The level of required risk-based capital (“RBC”) is calculated and reported annually. There are five outcomes to the RBC calculation set forth by the NAIC which are as follows: 1. No Action Level—If RBC is greater than 200%, no further action is required. 2. Company Action Level—If RBC is between 150%-200%, the insurer must prepare a report to the regulator outlining a comprehensive financial plan that identifies conditions that contributed to the insurer’s financial condition and proposes corrective actions. 3. Regulatory Action Level—If RBC is between 100%-150%, the state insurance commissioner is required to perform any examinations or analyses to the insurer’s business and operations that he or she deems necessary as well as issuing appropriate corrective orders. 4. Authorized Control Level—If RBC is between 70%-100%, this is the first point that the regulator may take control of the insurer even if the insurer is still technically solvent and is in addition to all the remedies available at the higher action levels. 5. Mandatory Control Level—If RBC is less than 70%, the regulator is required to take steps to place the insurer under its control regardless of the level of capital and surplus. At December 31, 2019, the ratio of adjusted capital to authorized control level risk based capital for each of our insurance company subsidiaries was above 300%. State laws for Florida, Hawaii, and Rhode Island permit an insurer to pay dividends or make distributions out of that part of statutory surplus derived from net operating profit and net realized capital gains. The applicable laws pertain to the state of domicile of each insurance company affiliate and provide calculations to determine the amount of dividends or distributions that can be made without the prior approval of the insurance regulatory authority and the amount of dividends or distributions that would require prior approval of the insurance regulatory authority. In the state of Florida, a dividend may be taken without regulatory approval if the dividend is equal to or less than the greater of 10% of the insurer’s surplus or the insurer’s net income. In the state of Rhode Island, a dividend may be taken without regulatory approval if the dividend is equal to or less than the lesser of 10% of the insurer’s surplus or the insurer’s net income excluding realized capital gains. The state of Hawaii restricts dividends without regulatory approval to the smaller of prior years’ net income or 10% of prior year’s surplus. Heritage P&C and NBIC have not paid dividends in any of the last three years. Zephyr paid dividends of $6.9 million and $7.6 million for the years ended December 31, 2019 and 2018. Statutory risk-based capital requirements may further restrict our insurance subsidiaries ability to pay dividends or make distributions if the amount of the intended dividend or distribution would cause statutory surplus to fall below minimum risk-based capital requirements. However, the consent order authorizing commencement of operations for Heritage P&C precluded payment of dividends without the prior approval of FLOIR until July 31, 2017. State insurance laws limits an insurer’s investment in equity instruments and also restricts investments in medium to low quality debt instruments. The Company’s insurance affiliates were in compliance with all investment restrictions at December 31, 2019 and 2018. Governmental agencies or certain quasi-governmental entities can levy assessments upon the Company in the states in which the Company writes policies. See Note 1 Basis of Presentation, Nature of Business and Significant Accounting Policies and Practices” The Company reported its insurance subsidiaries’ assets, liabilities and results of operations in accordance with GAAP, which varies from statutory accounting principles prescribed or permitted by state laws and regulations, as well as by general industry practices. The following items are principal differences between statutory accounting and GAAP: • Statutory accounting requires that the Company excluded certain assets, called non-admitted assets, from the balance sheet. • Statutory accounting requires the Company to expense policy acquisition costs when incurred, while GAAP allows the Company to defer and amortize policy acquisition costs over the estimated life of the policies. • Statutory accounting dictates how much of a deferred income tax asset the Company can admit on a statutory balance sheet. • Statutory accounting requires that the Company record certain investments at cost or amortized cost, while the Company records other investments at fair value; however, GAAP requires that we record all available for sale investments at fair value. • Statutory accounting requires that surplus notes, also known as surplus debentures, be recorded in statutory surplus, while GAAP requires the Company to record surplus notes as a liability. • Statutory accounting allows bonds to be carried at amortized cost or fair value based on the rating received from the Securities Valuation Office of the NAIC, while they are recorded at fair value for GAAP if designated as available for sale. • Statutory accounting requires unrealized gains and losses from equity securities to be reported as direct adjustments to surplus, but under GAAP ASU 2016-01 the reporting of unrealized gains and losses on equity securities are reported in net income • Statutory accounting allows ceding commission income to be recognized when written if the cost of acquiring and renewing the associated business exceeds the ceding commissions, but under GAAP such income is deferred and recognized over the coverage period. • Statutory accounting requires that unearned premiums and loss reserves be presented net of related reinsurance rather than on a gross basis under GAAP. • Statutory accounting requires a provision for reinsurance liability be established for reinsurance recoverable on paid losses aged over ninety days and for unsecured amounts recoverable from unauthorized reinsurers. Under GAAP there is no charge for uncollateralized amounts ceded to a company not licensed in the insurance affiliate’s domiciliary state and a reserve for uncollectable reinsurance is charged through earnings rather than surplus or equity. • Statutory accounting requires an additional admissibility test outlined in Statements on Statutory Accounting Principles, No. 101 and the change in deferred income tax is reported directly in capital and surplus, rather than being reported as a component of income tax expense under GAAP. The table below reconciles the Company’s consolidated GAAP net (loss) income to statutory net income of its insurance subsidiaries (in thousands): For the Year Ended December 31, 2019 2018 2017 Consolidated GAAP net income (loss) $ 28,636 $ 27,155 $ (1,119 ) (Decrease) increase due to: Deferred income taxes (339 ) (16,868 ) 32,644 Deferred acquisition costs (4,156 ) (31,377 ) 1,101 Surplus note interest — — (4 ) Non-statutory subsidiaries (37,005 ) (31,158 ) 5,410 Investment basis difference 247 335 446 Pre-acquisition income — — 20,839 Equity compensation (1,265 ) (2,408 ) (2,408 ) Convertible notes (1,613 ) (1,570 ) 1,051 Commission revenue 1,394 (6,289 ) (6,700 ) Change in fair value income statement (2,429 ) 2,078 — Lease accounting standard 137 — — Other 94 (4,372 ) (709 ) Statutory net (loss) income of insurance subsidiaries $ (16,299 ) $ (64,474 ) $ 50,553 The Company’s reinsurance subsidiary, Osprey, which was incorporated on April 23, 2013, is licensed as a Class 3a Insurer under The Bermuda Insurance Act 1978 and related regulations. Osprey is required to maintain statutory capital and surplus of at least $1.0 million and maintain liquid resources or have access to liquid resources equal to its maximum obligation for which it is responsible under the terms of any reinsurance arrangement to which it is a party. Osprey maintains sufficient collateral to comply with regulatory requirements as of December 31, 2019. Bermuda’s standard for financial statement reporting is U.S. GAAP.

The Company’s stop loss coverage per employee is $150,000 for which any excess cost would be covered by the reinsurer subject to an aggregate limit for losses in excess of $1.5 million which would provide up to $1.0 million of coverage. Any excess of the $1.5 million retention and the $1 million of aggregate coverage would be borne by the Company. The aggregate stop loss commences once our expenses exceed 125% of the annual aggregate expected claims.

Equity [Abstract]
Equity	Note 2 2 . Equity The total amount of authorized capital stock consists of 50,000,000 shares of common stock and 5,000,000 shares of preferred stock. As of December 31, 2019, the Company had 28,650,918 shares of common stock outstanding, 8,349,483, treasury shares of common stock and 345,534 unvested restricted common stock issued reflecting total paid-in capital of $329.6 million as of such date. Common Stock Holders of common stock are entitled to one vote for each share held on all matters subject to a vote of stockholders, subject to the rights of holders of any outstanding preferred stock. Accordingly, holders of a majority of the shares of common stock entitled to vote in any election of directors may elect all of the directors standing for election, subject to the rights of holders of any outstanding preferred stock. Holders of common stock will be entitled to receive ratably any dividends that the board of directors may declare out of funds legally available therefor, subject to any preferential dividend rights of outstanding preferred stock. Upon the Company’s liquidation, dissolution or winding up, the holders of common stock will be entitled to receive ratably its net assets available after the payment of all debts and other liabilities and subject to the prior rights of holders of any outstanding preferred stock. Holders of common stock have no preemptive, subscription, redemption or conversion rights. There is no redemption or sinking fund provisions applicable to the common stock. All outstanding shares of the Company’s capital stock (excluding restricted stock) are fully paid and nonassessable. Stock Repurchase Program On August 1, 2018, the Company announced that its Board of Directors authorized a stock repurchase program authorizing the Company to repurchase up to $50.0 million of its common stock through December 31, 2020 under our current Rule 10b5-1 trading plan, which allows the Company to purchase shares below a predetermined price per share. At December 31, 2019, the Company has the capacity to repurchase $33.8 million of its common shares until December 31, 2020. In addition, the Company acquired 237,620 shares for approximately $3.5million for the year ended December 31, 2019, that were not part of the publicly announced share repurchase authorization. These shares consisted of shares retained to cover payroll withholding taxes in connection with the vesting of restricted stock awards Dividends The declaration and payment of any future dividends will be subject to the discretion of the Board of Directors and will depend on a variety of factors including the Company’s financial condition and results of operations. Dividends For the year ended December 31, 2019, we recorded quarterly cash dividends of approximately $7.1 million as follows: Quarter Ended March 31, 2019 June 30, 2019 September 30, 2019 December 31, 2019 Cash dividend per common share $ 0.06 $ 0.06 $ 0.06 $ 0.06 Total cash dividends paid $ 1,806,944 $ 1,791,323 $ 1,772,063 $ 1,749,800 Record date March 15, 2019 June 14, 2019 September 16, 2019 December 16, 2019 Payment date April 3, 2019 July 3, 2019 October 3, 2019 January 6, 2020

Stock-Based Compensation

Stock-Based Compensation	12 Months Ended

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Stock-Based Compensation	Note 23 . Stock-Based Compensation Common Stock The Company has adopted the Heritage Insurance Holdings, Inc., Omnibus Incentive Plan (the “Plan”) effective on May 22, 2014. The Plan authorized 2,981,737 shares of common stock for issuance under the Plan for future grants. At December 31, 2019 there were 1,551,018 shares available for grant under the Plan. The Company recognizes compensation expense under ASC 718 for its stock-based payments based on the fair value of the awards. In 2018, the Company granted 155,801 restricted shares vesting over three to five years, to the Company’s executives and other key employees. No restricted stock was granted during the year ended December 31, 2019. The Plan authorizes the Company to grant stock options at exercise prices equal to the fair market value of the Company’s stock on the dates the options are granted. Any options granted would typically have a maximum term of ten years from the date of grant and vest primarily in equal annual installments over a range of one to five-year periods following the date of grant for employee options. If a participant’s employment relationship ends, the participant’s vested awards would remain exercisable for the shorter of a period of 30 days or the period ending on the latest date on which such award could have been exercisable. The fair value of each option grant is separately estimated for each grant date. The fair value of each option is amortized into compensation expense on a straight-line basis between the grant date for the award and each vesting date. The Company estimates the fair value of all stock option awards as of the date of the grant by applying the Black-Scholes-Merton multiple-option pricing valuation model. The application of this valuation model involves assumptions that are judgmental and highly sensitive in the determination of compensation expense. The Company has not granted any stock options since 2015 and all unexercised stock options have since been forfeited. Restricted Stock The Company has also granted shares of its common stock subject to certain restrictions under the Plan. Restricted stock awards granted to employee’s vest in equal installments generally over a five-year period from the grant date subject to the recipient’s continued employment. The fair value of restricted stock awards is estimated by the market price at the date of grant and amortized on a straight-line basis to expense over the period of vesting. Recipients of restricted stock awards have the right to receive dividends. Restricted stock activity for the three years ended December 31, 2019, 2018 and 2017 is as follows: Weighted-Average Grant-Date Fair Number of shares Value per Share Non-vested, at December 31, 2016 900,000 $ 18.42 Granted — — Vested (137,935 ) 16.53 Canceled and surrendered (87,065 ) 17.41 Non-vested, at December 31, 2017 675,000 $ 21.40 Granted 155,801 16.10 Vested (112,500 ) 16.35 Canceled and surrendered (112,500 ) 16.35 Non-vested, at December 31, 2018 605,801 $ 20.41 Granted — — Vested (22,647 ) 14.28 Canceled and surrendered (237,620 ) 14.82 Non-vested, at December 31, 2019 345,534 $ 19.56 Awards are being amortized to expense over the three to five year vesting period. Relating to the restricted stock the Company recognized $5.4 million, $5.3 million and $4.8 million of compensation expense for the years ended December 31, 2019, 2018 and 2017, respectively. At December 31, 2019, there was approximately $5.6 million, representing unrecognized compensation expense related to the non-vested restricted stock, substantially all of which is expected to be recognized over the next one-year period. During the year ended December 31, 2019, restricted shares were vested and released, of which 260,267 shares had been granted to employees. Of the shares released to employees, 237,620 shares were withheld by the Company to cover withholding taxes of $3.5 million. During 2018 and 2017, 112,500 and 87,065 shares, respectively, were withheld to cover withholding taxes of $1.8 million and $1.6 million respectively, arising from the vesting of restricted shares. We recognized no tax benefit from the restricted stock awards and related paid dividends for the years 2019, 2018 and 2017, respectively.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements include the accounts of Heritage Insurance Holdings, Inc. and its wholly-owned subsidiaries. The accompanying consolidated financial statements include the accounts of the Company and all other entities in which the Company has a controlling financial interest (none of which are variable interest entities). All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with United States Generally Accepted Accounting Principles (“U.S. GAAP”) requires us to make estimates and assumptions about future events that affect the amounts reported in our consolidated financial statements and accompanying notes. We evaluate our estimates on an ongoing basis when updated information related to such estimates becomes available. We base our estimates on historical experience and information available to us at the time these estimates are made. Actual results could differ materially from these estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company’s cash and cash equivalents include demand deposits with financial institutions and short-term, highly-liquid financial instruments with original maturities of three months or less when purchased. The carrying amounts reported in the consolidated balance sheets for interest bearing deposits approximate their fair value because of the short maturity of these financial instruments. The Company excludes from cash and cash equivalents negative cash balances that the Company has with an individual financial institution. The liability presents outstanding checks not yet presented to the financial institution and is reported in accounts payable and other liabilities.
Restricted Cash	Restricted Cash As of December 31, 2019, and 2018, restricted cash was $14.7 million and $12.3 million, respectively. For the years ended December 31, 2019 and 2018, Heritage P&C held approximately $9.0 million and $9.0 million relating to a reinsurance agreement with an entity that issued catastrophe (“CAT”) bonds, as Heritage P&C is contractually required to deposit certain installments of reinsurance premiums into a trust account and $5.7 million and $3.2 million in restricted cash relating to individual regulatory state deposits, respectively. The Company earned interest income of $28,969 and $36,532 on its restricted cash deposits.
Investments	Investments The Company classifies all of its investments in debt securities as available-for-sale and reports them at fair value. Subsequent to its acquisition of debt securities available-for-sale, the Company records changes in value through the date of disposition as unrealized holding gains and losses, net of tax effects, and includes them as a component of other comprehensive income. Equity securities are recorded at fair value with changes in fair value reflected in net income and presented with realized gains and losses. The Company includes realized gains and losses, which it calculates using the specific-identification method for determining the cost of securities sold, in net income. The Company amortizes any premium or discount on fixed maturities over the remaining maturity period of the related securities using the effective interest method and reports the amortization in net investment income. The Company recognizes dividends and interest income when earned. Quarterly, the Company performs an assessment of its debt securities available-for-sale to determine if any are “other-than-temporarily” impaired. An investment is impaired when the fair value of the investment declines to an amount less than the cost or amortized cost of that investment. As part of the assessment process, the Company determines whether the impairment is temporary or “other-than-temporary”. The Company bases its assessment on both quantitative criteria and qualitative information, considering a number of factors including, but not limited to: how long the security has been impaired; the amount of the impairment; the Company intends to sell the investment or it is more likely than not that the Company will have to sell the investment before it recovers the amortized cost or cost; the financial condition and near-term prospects of the issuer; whether the issuer is current on contractually-obligated interest and principal payments; key corporate events pertaining to the issuer and whether the market decline was affected by macroeconomic conditions. If the Company were to determine that a debt security or participation in a commercial mortgage loan was impaired and the Company either intends to sell the investment or it is more likely than not that the Company will have to sell the investment before it is able to recover the amortized cost or cost, then the Company would record the full amount of the impairment in its consolidated statement of operations and other comprehensive income. A large portion of the Company’s investment portfolio consists of debt securities available-for-sale, which may be adversely affected by changes in interest rates as a result of governmental monetary policies, domestic and international economic and political conditions and other factors beyond its control. A rise in interest rates would decrease the net unrealized holding gains of our investment portfolio, offset by the Company’s ability to earn higher rates of return on funds reinvested. Conversely, a decline in interest rates would increase the net unrealized holding gains of our investment portfolio, offset by lower rates of return on funds reinvested. Accumulated other comprehensive income consists solely of unrealized gains and losses on debt securities available-for-sale, net of income tax.
Fair Value	Fair Value Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants (an exit price). When reporting the fair values of the Company’s financial instruments, the Company prioritizes those fair value measurements into one of three levels based on the nature of the inputs, as follows: • Level 1—Assets and liabilities with values based on unadjusted quoted prices for identical assets or liabilities in an active market that the Company is able to access. • Level 2—Asset and liabilities with values based on quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets in markets that are not active; or valuation models with inputs that are observable, directly or indirectly for substantially the term of the asset or liability. • Level 3—certain inputs are unobservable (supported by little or no market activity) and significant to the fair value measurement. Unobservable inputs reflect the Company’s best estimate of what hypothetical market participants would use to determine a transaction price for the asset or liability at the reporting date based on the best information available in the circumstances. The Company estimates the fair value of its investments using the closing prices on the last business day of the reporting period, obtained from active markets such as the NYSE and NASDAQ. For securities for which quoted prices in active markets are unavailable, the Company uses observable inputs such as quoted prices in inactive markets, quoted prices in active markets for similar instruments, benchmark interest rates, broker quotes and other relevant inputs. The Company does not have any investments in its portfolio which require the use of unobservable inputs. The Company’s estimate of fair value reflects the interest rate environment that existed as of the close of business on December 31, 2019. Changes in interest rates after December 31, 2019 may affect the fair value of the Company’s investments. The Company believes the carrying amounts of its cash and cash equivalents, accounts receivable, accounts payable, accrued expenses, and other current liabilities approximate their fair values at December 31, 2019 and 2018, due to the immediate or short-term maturity of these instruments. The Company’s non-financial assets, such as goodwill and property, plant and equipment are carried at cost until there are indicators of impairment and are recorded at fair value only when an impairment charge is recognized. Long term debt is recorded at carrying value, see Note 14 – Long-Term Debt
Premiums	Premiums The Company records direct and assumed premiums written as revenue net of ceded amounts on a daily pro rata basis over the contract period of the related in force policies or reinsurance contract. For any portion of premiums not earned at the end of the reporting period, the Company records an unearned premium liability. Premiums receivable represents amounts due from our policyholders for billed premiums and related policy fees. We perform a policy-level evaluation to determine the extent to which the balance of premiums receivable exceeds the balance of unearned premiums. We then age any resulting exposure based on the last date the policy was billed to the policyholder, and we establish an allowance for credit losses for any amounts outstanding for more than 90 days. When we receive payments on amounts previously charged off, we reduce bad debt expense in the period we receive the payment. Balances in premiums receivable and the associated allowance account are removed upon cancellation of the policy due to non-payment. We recorded $290,300 allowance for the year ended December 31, 2019. We recorded no allowance for the years ended December 31, 2018 and 2017, respectively. Bad debt expense related to uncollectible premiums was $290,300, $0 and $0 for the years ended December 31, 2019, 2018 and 2017, respectively. When the Company receives premium payments from policyholders prior to the effective date of the related policy, the Company records an advance premiums liability. On the policy effective date, the Company reduces the advance premium liability and records the premiums as described above.
Policy Acquisition Costs	Policy Acquisition Costs The Company incurs policy acquisition costs that vary with, and are directly related to, the production of new business. Policy acquisition costs consist of the following four items: (i) commissions paid to outside agents at the time of policy issuance; (ii) policy administration fees paid to a third-party administrator at the time of policy issuance; (iii) premium taxes; and (iv) inspection fees. The Company capitalizes policy acquisition costs to the extent recoverable, then the Company amortizes those costs over the contract period of the related policy. At each reporting date, the Company determines whether it has a premium deficiency. A premium deficiency would result if the sum of the Company’s expected losses, deferred policy acquisition costs, and policy maintenance costs (such as costs to store records and costs incurred to collect premiums and pay commissions) exceeded the Company’s related unearned premiums plus investment income. Should the Company determine that a premium deficiency exists, the Company would write off the unrecoverable portion of deferred policy acquisition cost. We earn ceding commission on its gross and net quota share reinsurance contracts. Our accounting policy is to allocate ceding commission between policy acquisition costs and general and administrative expenses for financial reporting purposes. Ceding commission is allocated between policy acquisition costs and general and administrative expenses based upon the proportion these costs bear to production of new business. For the years ended December 31, 2019 and 2018, we earned ceding commission income of $62.4 million and $73.0 million of which $47.0 million and $54.9 million was allocable to policy acquisition costs. Ceding commission income is deferred and recognized over the quota share contract period. The amount and rate of ceding reinsurance commissions earned on the net quota share contract can slide within a prescribed minimum and maximum, depending on loss performance and how future losses develop.
Reinsurance	Reinsurance The Company follows industry practice of reinsuring a portion of our risks. Reinsurance involves transferring, or “ceding”, all or a portion of the risk exposure on policies the Company writes to another insurer, known as a reinsurer. To the extent that the Company’s reinsurers are unable to meet the obligations they assume under the Company’s reinsurance agreements, the Company remains liable for the entire insured loss. The Company’s reinsurance agreements are generally short-term, prospective contracts. The Company records an asset, prepaid reinsurance premiums, and a liability, reinsurance payable, for the entire contract amount upon commencement of new reinsurance agreements. The Company amortizes its prepaid reinsurance premiums over the 12-month contract period. When the Company incurs losses recoverable under its reinsurance program, the Company records amounts recoverable from its reinsurers on paid losses plus an estimate of amounts recoverable on unpaid losses. The estimate of amounts recoverable on unpaid losses is a function of the Company’s liability for unpaid losses associated with the reinsured policies; therefore, the amount changes in conjunction with any changes to the estimate of unpaid losses. Given that an estimate of amounts recoverable from reinsurers on unpaid losses may change at any point in the future because of its relation to the Company’s reserves for unpaid losses, a reasonable possibility exists that an estimated recovery may change significantly from initial estimates. The Company estimates uncollectible amounts receivable from reinsurers based on an assessment of factors including the creditworthiness of the reinsurers and the adequacy of collateral obtained, where applicable. The Company recorded no uncollectible amounts under its reinsurance program or bad debt expense related to reinsurance for the years ended December 31, 2019, 2018 and 2017. The Company remains liable for claims payments if any reinsurer is unable to meet its obligations under the reinsurance agreements. 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 concentration of credit risk arising from similar geographic regions, activities or economics characteristics of the reinsurers to minimize its exposure to significant loses from reinsurers insolvencies. The Company contracts with several reinsurers to secure its annual reinsurance coverage, which the excess of loss treaties generally becomes effective June 1st each year. The Company purchases reinsurance each year taking into consideration probable maximum losses and reinsurance market condition.
Long-Lived Assets-Property and Equipment	Long-Lived Assets—Property and Equipment Property and equipment is stated at cost less accumulated depreciation and amortization. Depreciation is calculated on a straight-line basis over the estimated useful lives as follows: building—40 years; computer hardware and software 3—years; office and furniture equipment—3 to 7 years. Leasehold improvements are amortized over the shorter of the lease term or the asset’s useful life. Expenditures for improvements are capitalized to the property accounts. Replacements and maintenance and repairs that do not improve or extend the life of the respective assets are expensed as incurred.
Leases	Leases We lease office space under operating leases with expiration dates through 2023. We determine whether an arrangement constitutes a lease and record lease liabilities and right-of-use assets on our consolidated balance sheets at lease commencement. We primarily use our incremental borrowing rates for our operating leases (rates are not readily determinable) and implicit rates for our financing leases in determining the present value of lease payments. For short-term leases, we record rent expense in our consolidated statements of operations on a straight-line basis over the lease term and record variable lease payments as incurred.
Business Acquisition	Business Acquisition The application of the purchase method of accounting for business combinations requires the use of significant estimates and assumptions in determining the fair value of assets acquired and liabilities assumed in order to properly allocate the fair value of the acquired business. The estimates of the fair value of the assets acquired and liabilities assumed are based upon assumptions believed to be reasonable using established valuation techniques that consider a number of factors and when appropriate, valuations performed by independent third-party appraisers. Assets acquired, and liabilities assumed in connection with business combinations are recorded based on their respective fair values at the date of acquisition.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill represents the excess of costs over the fair value of net assets acquired. Goodwill is subject to evaluation for impairment using a fair value-based test. This evaluation is performed annually, during the fourth quarter or more frequently if facts and circumstances warrant. The Company uses a qualitative approach to test goodwill for impairment by first assessing qualitative factors to determine whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. The Company applies this qualitative approach as of October 1 annually to any and all reporting units. If required following the qualitative assessment, the first step in the goodwill impairment test involves comparing the fair value of each of a reporting unit to the carrying value of a reporting unit. If the carrying value of a reporting unit exceeds the fair value of the reporting unit, the Company is required to proceed to the second step. In the second step, the fair value of the reporting unit would be allocated to the assets (including unrecognized intangibles) and liabilities of the reporting unit, with any residual representing the implied fair value of goodwill. An impairment loss would be recognized if, and to the extent that, the carrying value of goodwill exceeded the implied value. The Company reviews amortizable intangible assets for impairment whenever events or circumstances indicate that carrying amounts may not be recoverable. If the Company concludes that impairment exists, the carrying amount is reduced to fair value. No impairment was recognized in any period presented.
Impairment of Long-Lived Assets Including Intangible Assets Subject to Amortization	Impairment of Long-Lived Assets Including Intangible Assets Subject to Amortization The Company assesses the recoverability of long-lived assets when events or circumstances indicate that the assets might have become impaired. The Company determines whether the assets can be recovered from undiscounted future cash flows and, if not recoverable, the Company recognizes impairment to reduce the carrying value to fair value. Recoverability of long-lived assets is dependent upon, among other things, the Company’s ability to maintain profitability, so as to be able to meet its obligations when they become due. No impairment was recognized in any period presented.
Unpaid Losses and Loss Adjustment Expenses	Unpaid Losses and Loss Adjustment Expenses The Company’s reserves for unpaid losses and loss adjustment expenses represent the estimated ultimate cost of settling all reported claims plus all claims we incurred related to insured events that have occurred as of the reporting date, but that policyholders have not yet reported to the Company (incurred but not reported, or “IBNR”). The Company estimates its reserves for unpaid losses and loss adjustment expenses using individual case-based estimates for reported claims and actuarial estimates for IBNR losses. The Company continually reviews and adjusts its estimated losses as necessary based on industry development trends, the Company’s evolving claims experience and new information obtained. If the Company’s unpaid losses and loss adjustment expenses are considered to be deficient or redundant, the Company increases or decreases the liability in the period in which it identifies the difference and reflects the change in its current period results of operations. Though the Company’s estimate of the ultimate cost of settling all reported and unreported claims may change at any point in the future, a reasonable possibility exists that its estimate may vary significantly in the near term from the estimated amounts included in the Company’s consolidated financial statements. The Company reports its reserves for unpaid losses and loss adjustment expenses gross of the amounts related to unpaid losses recoverable from reinsurers and reports loss and loss adjustment expenses net of amounts ceded to reinsurers. The Company does not discount its loss reserves for financial statement purposes.
Other Revenue	Other revenue Our insurance affiliates may charge policyholders a policy fee on each policy written; to the extent these fees are not subject to refund, and the Company recognizes the income immediately when collected. The Company also charges pay-plan fees to policyholders that pay its premiums in more than one installment and records the fees as income when collected. Other income also includes rental income due under non-cancelable leases for space at the Company’s commercial property.
Assessment	Assessment Guaranty fund and other insurance-related assessments imposed upon the Company’s insurance company affiliates are recorded as policy acquisition costs in the period the regulatory agency imposes the assessment. To recover guaranty or other insurance-related assessments, the Company in turn submits a plan for recoupment to the Insurance Commissioner for approval and upon approval, begins collecting a policy surcharge that will allow it to collect the prior year’s assessments. There were no assessments during the periods presented. The Company collects other assessments imposed upon policyholders as a policy surcharge and records the amounts collected as a liability until the Company remits the amounts to the regulatory agency that imposed the assessment.
Convertible Notes	Convertible Notes In August 2017 and September 2017, the Company issued collectively $136.8 million of 5.875% Convertible Senior Notes (the “Convertible Notes”) due August 1, 2037. The Convertible notes are accounted for in accordance with ASC 470-20. At the time of issuance and until December 1, 2017, the Company recorded the fair value of the derivatives on its balance sheet at fair value with changes in the values of these derivatives reflected in the consolidated statement of operations. As of December 31, 2019, the Company has $23.4 million of the Convertible Notes outstanding. Beginning December 1, 2017, the conversion option of the Convertibles Notes qualifies for the equity classification and will no longer be accounted for as a separate derivative instrument liability in accordance with applicable U.S. GAAP guidance. The Company separately accounts for the liability and equity components of Convertible Notes that can be settled in cash by allocating the proceeds from issuance between the liability component and the embedded conversion option, or equity component, in accordance with accounting for convertible debt instruments that may be settled in cash (including partial cash settlement) upon conversion. The value of the equity component is calculated by first measuring the fair value of the liability component, using the interest rate of a similar liability that does not have a conversion feature, as of the issuance date. The difference between the proceeds from the convertible debt issuance and the amount measured as the liability component is recorded as the equity component with a corresponding discount recorded on the debt. The Company recognizes the accretion of the resulting discount using the effective interest method as part of interest expense in its consolidated statements of operations.
Debt Extinguishment	Debt Extinguishment The Company has reacquired convertible senior notes over a series of transactions. In accordance with ASC 470 “ Debt
Debt Issuance and Discount Costs	Debt Issuance and Discount Costs In connection with the issuance of debt, any debt issuance and discount costs are reflected on the balance sheet as an offset to long-term debt and amortized using the effective interest method over the life of the underlying debt instrument.
Stock-Based Compensation	Stock-Based Compensation The Company measures stock-based compensation at the grant date based on the fair value of the award and recognizes stock-based compensation expense over the requisite vesting period. Determining the fair value of stock option awards requires judgment, including estimating stock price volatility, forfeiture rates and expected option life. Restricted stock awards are valued based on the fair value of the stock on the grant date and the related compensation expense is recognized over the vesting period.
Earnings Per Share	Earnings Per Share The Company reports both basic earnings per share and diluted earnings per share. To calculate basic earnings per share, the Company divides net income attributable to common shareholders by the weighted-average number of shares outstanding during the period, including vested restricted shares. The Company calculates diluted earnings per share by dividing net income attributable to common shareholders by the weighted-average number of shares, and the effect of share equivalents, vested and unvested restricted shares and convertible notes outstanding during the period using the treasury stock method to calculate common stock equivalents.
Income Tax	Income tax Income taxes are accounted for under the asset and liability method, that recognizes the amount of income taxes payable or refundable for the current year and recognizes deferred tax assets and liabilities based on the tax rates expected to be in effect during the periods in which the temporary differences reverse. Temporary differences arise when income or expenses are recognized in different periods in the consolidated financial statements than on the tax returns. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that all, or some portion, of the benefits related to deferred tax assets will not be realized. Income taxes includes both, estimated federal and state income taxes.
Concentrations of Risk	Concentrations of Risk The Company’s current operations subject us to the following concentrations of risk: • Revenue—The Company writes residential property and liability policies exclusively. • Geographic—The Company writes its premium in coastal states in the southeastern and northeastern United States and Hawaii • Group concentration of credit risk—All of the Company’s reinsurers engage in similar activities and have similar economic characteristics that could cause their ability to repay us to be similarly affected by changes in economic or other conditions. • Credit risk—The Company chooses to deposit all its cash at twelve financial institutions. The Company mitigates its geographic and group concentrations of risk by entering into reinsurance contracts with highly rated, financially-stable reinsurers, and by securing irrevocable letters of credit from reinsurers when necessary. With regard to cash, the Company had $267.4 million and $244.6 million in excess of Federal Deposit Insurance Corporation (“FDIC”) insurance limits at December 31, 2019 and 2018, respectively. Deposits held in non- interest-bearing transaction accounts are combined with interest-bearing accounts and are insured up to $250,000.
Reclassifications	Reclassification Certain prior year amounts have been reclassified to conform to the current year presentation.
Recent Accounting Pronouncements	Recently Adopted Accounting Pronouncements In February 2016, the FASB updated guidance on the accounting for leases that requires lessees to recognize a right-to-use asset and a lease liability for leases with terms of more than 12 months and retains the two classifications of a lease as either an operating or finance lease. The updated guidance was effective for reporting periods after December 31, 2018 and required that the earliest comparative period presented include the measurement and recognition of exiting leases with an adjustment to equity as if the updated guidance had always been applied. Alternatively, an entity may elect to recognize a cumulative effect adjustment to the opening balance of retained earnings in the year adopted. Early adoption was permitted. We adopted the guidance prospectively during the first quarter of 2019. As part of our adoption, we elected not to reassess historical lease classification or recognize short-term leases on our balance sheet. At implementation, we recorded approximately $2.5 million as right-of-use operating and financing We did not recognize an opening adjustment to retained earnings. Note 8 Accounting Pronouncements Not Yet Adopted The Company describes below recent pronouncements that may have a significant effect on its consolidated financial statements or on its disclosures upon future adoption. The Company does not discuss recent pronouncements that are not anticipated to have an impact on, or are unrelated to, its financial condition, results of operations, or related disclosures. In December 2019, The FASB issued ASU 2019-12— Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, Topic 740 . In November 2019, the FASB issued ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Financial Instruments-Credit Losses (Topic 326): Targeted Transition Relief Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments Financial Instruments-Overall Recognition and Measurement of Financial Assets and Financial Liabilities In August 2018, the FASB issued ASU 2018-12 , Financial Services – Insurance (Topic 944) Targeted Improvements to the Accounting for Long-Duration Contracts In March 2018, the FASB issued ASU 2018-04, Investments-Debt Securities (Topic 320) and Regulated Operations (Topic 980). Investments-Debt Securities Regulated Operations In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other FASB ASU 2016-13 Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments The updated guidance also amends the current other-than-temporary impairment model for available-for-sale debt securities by requiring the recognition of impairments relating to the credit losses through an allowance account and limits the amount of credit loss to the difference between a security’s amortized costs basis and its fair value. Any adjustments identified will be recorded in net realized and unrealized gains (losses) on the Company’s Consolidated Statement of Operations and Other Comprehensive Income. In addition, the Company will no longer use as a measurement the length of time a security has been in an unrealized loss position in determining if a credit loss exists. The updated guidance is effective for the quarter ended March 31, 2020. The implementation primarily impacts the Company’s debt securities and reinsurance recoverable. The cumulative effect adjustment, if any will be recognized to the Company’s retained earnings. The adoption of this standard is not expected to be material to our financial position, results of operations or cash flows. No other new accounting pronouncement issued or effective during the fiscal year had or is expected to have a material impact on our consolidated financial statements or disclosures.
