Use of Estimates. Business Acquisitions. Before the adoption of Accounting Standards Update No. 2017-01, in-place in-place in-place After the adoption of Accounting Standards Update No. 2017-01 during the fourth quarter of 2017, the Company evaluates whether substantially all of the fair value of the gross assets acquired in a real estate transaction is concentrated in a single identifiable asset or group of similar identifiable assets. If such concentration is substantial, the transaction is accounted for as an asset acquisition. As a result, the cost of acquiring real estate is allocated to the individual assets based on the relative fair values of the individual assets. Acquisition related costs are capitalized and allocated among the assets acquired. Cash and Cash Equivalents. Available-for-Sale available-for-sale available-for-sale first-in first-out The Company reviews fixed-maturity securities for other-than-temporary impairment on a monthly basis. When the fair value of any investment is lower than its cost, an assessment is made to determine whether the decline is temporary or other-than-temporary. If the decline is determined to be other-than-temporary, the investment is written down to fair value and an impairment loss is recognized in income in the period in which the Company makes such determination. When reviewing impaired securities, the Company considers its ability and intent to hold these securities and whether it is probable that the Company will be required to sell these securities prior to their anticipated recovery or maturity. For the fixed-maturity securities that the Company intends to sell or it is probable that the Company will have to sell before recovery or maturity, the unrealized losses are recognized as other-than-temporary losses in income. In instances where there are credit related losses associated with the impaired fixed-maturity securities for which the Company asserts that it does not have the intent to sell, and it is probable that the Company will not be required to sell until a market price recovery or maturity, the amount of the other-than-temporary impairment loss related to credit losses is recognized in income, and the amount of the other-than-temporary impairment loss related to other non-credit When determining impairment due to a credit related loss, the Company carefully considers factors such as the issuer’s financial ratios and condition, the security’s current ratings and maturity date, and overall market conditions in estimating the cash flows expected to be collected. The expected cash flows discounted at the effective interest rate of the security implicit at the date of acquisition is then compared with the security’s amortized cost at the measurement date. A credit loss is incurred when the present value of the expected cash flows is less than the security’s amortized cost. The Company considers various factors in determining whether an individual security is other-than-temporarily impaired (see Available-for-Sale Equity Securities. Equity Securities Short-Term Investments. Limited Partnership Investments. Limited Partnership Investments The Company generally recognizes its share of the limited partnership’s earnings or losses on a three-month lag. Pursuant to U.S. GAAP, these limited partnerships which are private equity funds must measure their investments at fair value and reflect the unrealized gains and losses in the fair value of their investments on their statement of income. As a result, the carrying value of limited partnership investments at each reporting date approximates their estimated fair value. Investment in Unconsolidated Joint Venture. When evidence indicates an impairment may occur, the Company evaluates whether a decline in value is other than temporary. Evidence may include continuing operating losses of the joint venture, a declining occupancy rate, a decrease in real estate value, and an oversupply of rental property in close vicinity to the investment property. Should available evidence indicate the recovery of the initial investment is less likely, the Company would compare the carrying value of the investment with its expected residual value and recognize an impairment loss in earnings. Assets Held for Sale. In determining the fair value of the assets less costs to sell, the Company primarily relies on the value determined by an independent appraiser. If the estimated fair value less costs to sell is less than the carrying value of the asset, the asset is written down to its estimated fair value less costs to sell and an impairment loss is recognized in the consolidated statement of income. Depreciation is not recorded while assets are classified as held for sale. Real Estate Investments Deferred policy acquisition costs. The method followed in computing DAC limits the amount of such deferred costs to their estimated realizable value, which gives effect to the gross premium earned, related investment income, unpaid losses and loss adjustment expenses and certain other costs expected to be incurred as the premium is earned. DAC is reviewed to determine if it is recoverable from future premium income, including investment income. If such costs are determined to be unrecoverable, they are expensed at the time of determination. The amount of DAC considered recoverable could be reduced in the near term if the estimates of total revenues discussed above are reduced or permanently impaired as a result of the disposition of a line of business. The amount of amortization of DAC could be revised in the near term if any of the estimates discussed above are revised. Property and Equipment. internal-use Impairment of Long-Lived Assets. Intangible Assets. in-place Lease Acquisition Costs. Long-Term Debt. To determine the carrying values of the liability and equity components at issuance, the Company measures the fair value of a similar liability, including any embedded features other than the conversion option, and assigns such value to the liability component. The liability component’s fair value is then subtracted from the initial proceeds to determine the carrying value of the debt instrument’s equity component, which is included in additional paid-in Any embedded feature other than the conversion option is evaluated at issuance to determine if it is probable that such embedded feature will be exercised. If the Company concludes that the exercisability of that embedded feature is not probable, the embedded feature is considered to be non-substantive Transaction costs related to issuing a debt instrument that embodies both liability and equity components are allocated to the liability and equity components in proportion to the allocation of the proceeds and accounted for as debt issuance costs and equity issuance costs, respectively. Debt issuance costs are capitalized and presented as a deduction from the carrying value of the debt. Both debt discount and deferred debt issuance costs are amortized to interest expense over the expected life of the debt instrument using the effective interest method. Equity issuance costs are a reduction to the proceeds allocated to the equity component. Prepaid Share Repurchase Forward Contract. paid-in Losses and Loss Adjustment Expenses. The estimates of unpaid losses and LAE are subject to trends in claim severity and frequency and are continually reviewed. As part of the process, the Company reviews historical data and considers various factors, including known and anticipated regulatory and legal developments, changes in social attitudes, inflation and economic conditions. As experience develops and other data becomes available, these estimates are revised, as required, resulting in increases or decreases to the existing unpaid losses and LAE. Adjustments are reflected in the results of operations in the period in which they are made and the liabilities may deviate substantially from prior estimates. Losses and LAE ceded to or recovered from reinsurers are recorded as a reduction to losses and LAE on the consolidated statement of income. Advance Premiums Premium Revenue Reinsurance . st Certain of the Company’s current reinsurance contracts contain retrospective provisions including terms and conditions that adjust premiums, increase the amount of future coverage, or result in profit commissions based on the loss experience under the contracts. In such cases, a with-and-without The Company receives ceding commissions from ceding gross written premiums to a third-party reinsurer under one flood quota share reinsurance contract. The ceding commissions represent the reimbursement of the Company’s policy acquisition, underwriting and other operating expenses. Ceding commissions received cover a portion of premium taxes and agent commissions capitalized by the Company and a portion of non-capitalized pro-rata Reinsurance Recovered in Advance on Unpaid Losses. Premium Revenue. pro-rata Policy Fees. Florida Insurance Guaranty Association Assessments. in-force obligated-to-write in-force Foreign Currency. Non-monetary Income Taxes. tax-allocation The Company accounts for income taxes in accordance with U.S. GAAP, resulting in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term “more likely than not” means a likelihood of more than fifty percent; the terms “examined” and “upon examination” also include resolution of the related appeals or litigation processes, if any.

The scheduled contractual maturities of fixed-maturity securities at December 31, 2018 and 2017 are as follows: December 31, 2018 2017 Cost or Amortized Cost Estimated Fair Value Cost or Amortized Cost Estimated Fair Value Available-for-sale Due in one year or less $ 50,659 $ 50,574 $ 35,386 $ 35,364 Due after one year through five years 117,826 116,498 116,378 115,766 Due after five years through ten years 11,602 11,253 57,415 58,984 Due after ten years 4,583 4,398 26,454 27,370 $ 184,670 $ 182,723 $ 235,633 $ 237,484 Sales of Available-for-Sale Fixed-Maturity Securities Proceeds received, and the gross realized gains and losses from sales of available-for-sale fixed-maturity securities, for the years ended December 31, 2018, 2017 and 2016 were as follows: Proceeds Gross Realized Gains Gross Realized Losses Year ended December 31, 2018 $ 81,809 $ 1,293 $ (570 ) Year ended December 31, 2017 $ 31,759 $ 2,176 $ (181 ) Year ended December 31, 2016 $ 40,454 $ 604 $ (79 ) Other-than-temporary Impairment The Company regularly reviews its individual investment securities for other-than-temporary impairment. The Company considers various factors in determining whether each individual security is other-than-temporarily impaired, including- • the financial condition and near-term prospects of the issuer, including any specific events that may affect its operations or earnings; • the length of time and the extent to which the market value of the security has been below its cost or amortized cost; • general market conditions and industry or sector specific factors and other qualitative factors; • nonpayment by the issuer of its contractually obligated interest and principal payments; and • the Company’s intent and ability to hold the investment for a period of time sufficient to allow for the recovery of costs. For the year ended December 31, 2018, the Company recognized $80 of impairment loss on one fixed-maturity security in the consolidated statement of income. For the year ended December 31, 2017, the Company recognized impairment losses of $428 related to the sale of four intent-to-sell fixed-maturity securities. For the year ended December 31, 2016, the Company recognized $1,565 of impairment losses on four fixed-maturity securities, representing $1,335 of additional losses recorded during the period and $230 of the net change recorded in other comprehensive income.

These partnerships are private equity funds managed by general partners who make decisions with regard to financial policies and operations. As such, the Company is not the primary beneficiary and does not consolidate these partnerships. In February 2018, the Company entered into a subscription agreement to invest $5,000 with a limited partnership specializing in real estate private equity funds and portfolios. Subsequently, in September 2018, the Company increased its aggregate investment commitment with this limited partnership to $10,000. The following table provides information related to the Company’s investments in limited partnerships: December 31, 2018 December 31, 2017 Investment Strategy Carrying Value Unfunded Balance (%) (a) Carrying Value Unfunded Balance (%) (a) Primarily in senior secured loans and, to a limited extent, in other debt and equity securities of private U.S. lower-middle-market companies.

(j) Expected to have an eight-year term after the final fund closing date, which has yet to be determined. The following is the aggregated summarized unaudited financial information of limited partnerships included in the investment strategy table above, which in certain cases is presented on a three-month lag due to the unavailability of information at the Company’s respective balance sheet dates. In applying the equity method of accounting, the Company uses the most recently available financial information provided by the general partner of each of these partnerships. The financial statements of these limited partnerships are audited annually. Years Ended December 31, 2018 2017 2016 Operating results: Total income $ 1,821,935 $ 409,169 $ 310,998 Total expenses 146,079 105,281 185,126 Net income (loss) $ 1,675,856 $ 303,888 $ 125,872 December 31, 2018 2017 Balance Sheet: Total assets $ 6,689,792 $ 4,381,321 Total liabilities $ 394,029 $ 382,310 For the years ended December 31, 2018, 2017 and 2016, the Company recognized net investment income of $4,430, $2,334 and $1,207, respectively, for these investments. At December 31, 2018 and 2017, the Company’s cumulative contributed capital to the partnerships existing at each respective balance sheet date totaled $28,354 and $21,172, respectively, and the Company’s maximum exposure to loss aggregated $32,293 and $23,184, respectively. During the year ended December 31, 2018, the Company received in cash a return on investment of $2,345 and a return of capital of $158. During the year ended December 31, 2017, the Company received total cash distributions of $12,639, representing $11,758 of returned capital and $881 of return on investment. Included in the return of capital was $11,626 from one limited partnership the Company withdrew from in February 2017. During the year ended December 31, 2016, the Company received in cash $544 of return on investment. For the years ended December 31, 2018, 2017 and 2016, the Company recognized its share of earnings or losses based on the respective partnership’s statement of income. The carrying value of these investments approximates the amount the Company expected to recover at December 31, 2018 and 2017. d) Investment in Unconsolidated Joint Venture Melbourne FMA, LLC, a wholly owned subsidiary, currently has a 90% equity interest in FMKT Mel JV, LLC (“FMJV”), a Florida limited liability company treated as a joint venture under U.S. GAAP. FMJV is deemed a variable interest entity due to its lack of sufficient equity to finance its operations without direct or indirect additional financial support from parties to the joint venture. Although Melbourne FMA holds a majority interest in FMJV, certain major economic decisions specified in the agreement are not under Melbourne FMA’s control. As a result, Melbourne FMA is not the primary beneficiary and is not required to consolidate FMJV. In January 2016, FMJV sold a portion of its outparcel land for gross proceeds of $829, of which $515 was used to repay a portion of the construction loan obtained for its real estate development project. FMJV recognized a $404 gain on the outparcel sale of which $383 was allocated to the Company in accordance with the profit allocation specified in the operating agreement. On December 15, 2016, FMJV distributed its entire equity interest in FMKT Mel Manager, LLC (“FMKT MGA”), its wholly owned subsidiary, to Melbourne FMA and the other member, each of which received 90% and 10%, respectively. In addition to operating a retail shopping center business, FMKT MGA owned land which included two outparcels. Melbourne FMA accounted for this transaction as a business step acquisition using the fair value method and, as a result, recognized a $4,005 gain on remeasurement of previously held interest. The gain represented the difference between the fair value of the 90% equity interest and its carrying value under the equity method. The fair value of the equity interest was comprised of the fair value of FMKT MGA’s underlying assets primarily determined by an independent appraiser offset by the fair value of liabilities assumed on the date of distribution. Inputs used by the appraiser included, but were not limited to, information about market and surrounding environments, demographics, and the sale or rent of similar types of property within the vicinity. Due to their short-term nature, the carrying value of current assets and assumed liabilities, including a variable interest rate revolving credit line, approximated fair value. See Pineda Landings - Melbourne, Florida In March 2017, FMJV sold a portion of its outparcel land for gross proceeds of $825 and recognized a $331 gain on sale of which $199 was allocated to the Company in accordance with the profit allocation specified in the operating agreement. During 2017, FMKT MGA was merged with Melbourne FMA, LLC. In June 2018, FMJV sold one of its outparcels for $849 and recognized a gain of $438. At December 31, 2018 and 2017, the Company’s maximum exposure to loss relating to the variable interest entity was $845 and $1,304, respectively, representing the carrying value of the investment. At December 31, 2018 and 2017, there was no undistributed income from this equity method investment. There was an undistributed loss, after an equity distribution, of $25 at December 31, 2016, the amounts of which were included in the Company’s consolidated retained income. For the year ended December 31, 2018, the Company received a cash distribution of $763, representing a combined distribution of $68 in earnings and $695 in capital. For the year ended December 31, 2017, the Company received a cash distribution of $564, representing a combined distribution of $147 in earnings and $417 in capital. The limited liability company members received no cash distributions during 2016. The following tables provide FMJV’s summarized unaudited financial results and the unaudited financial positions: Years Ended December 31, 2018 2017 2016 Operating results: Total revenues $ 438 $ 331 $ — Total expenses 100 483 — Net income (loss) $ 338 $ (152 ) $ — The Company’s share of net income (loss) (a) $ 304 $ (234 ) $ — (a) Included in net investment income in the Company’s consolidated statements of income. Gain from the sale of the outparcel during 2017 was allocated in accordance with the method specified in the operating agreement.

In 2017, FMJV decided to terminate its development plan for nearby land, thereby expensing $382 of deferred costs associated with the land feasibility study. FMJV’s assets at December 31, 2018 and 2017 included primarily outparcels for sale or lease which have increased in value since the adjacent retail shopping center was completed. The Company determined that there was no impairment loss associated with these assets for the years ended December 31, 2018 and 2017. e) Assets Held for Sale On November 5, 2018, Greenleaf Capital, LLC, the Company’s wholly-owned subsidiary, listed its 10-acre waterfront property in Treasure Island, Florida for sale. The property primarily consists of land, commercial and marina buildings. This property, which is owned by the real estate division, was reclassified from real estate investments to assets held for sale in the Company’s consolidated balance sheet. The recording of depreciation on the buildings ceased November 5, 2018 resulting in a $34 decrease in depreciation expense in 2018 compared with 2017. f) Real Estate Investments Real estate investments include buildings with office and retail space for lease, outparcels, and one marina. Real estate investments consist of the following as of December 31, 2018 and 2017: December 31, 2018 2017 Land $ 23,884 $ 26,315 Land improvements 8,717 9,904 Building 19,201 21,284 Tenant and leasehold improvements 1,261 1,204 Other 5,266 3,050 Total, at cost 58,329 61,757 Less: accumulated depreciation and amortization (3,839 ) (3,399 ) Real estate investments $ 54,490 $ 58,358 In November 2018, the Company reclassified a net carrying value of $9,810 from real estate investments to assets held for sale.

On January 26, 2018, the Company gained full ownership of this limited liability company by acquiring the noncontrolling interest for $539 which was reported in the Company’s consolidated statement of stockholders’ equity. Prior to the acquisition date, the Company already consolidated this limited liability company as its primary beneficiary. As a result, the acquisition was accounted for as an equity transaction. No gain or loss was recognized as there was no change in control.

Business Acquisitions	Note 7 — Business Acquisitions Sorrento Hills Village - Sorrento, Florida On August 16, 2016, the Company’s wholly owned subsidiary, Greenleaf Capital, LLC, assigned the right to purchase the developed property to its subsidiary, Sorrento PBX, LLC. Sorrento PBX simultaneously exercised the purchase option and acquired the property from Sorrento Retail Investments, LLC. The acquired assets included a retail shopping center and appurtenant facilities in Sorrento, Florida as well as existing tenant lease agreements to use the property. The purchase price was $12,250, which was determined using a predetermined capitalization rate and the projected net operating income of the property. The Company recognized a $2,071 gain on bargain purchase, resulting primarily from a favorable fair value at the date of acquisition as compared with the Company’s purchase price. The Company relied on an independent appraisal report, which is based on the weighted results of two valuation approaches, in determining the estimated fair values of the significant assets acquired. This acquisition was financed in part by the proceeds from the issuance of a 3.75% promissory note. See Note 14 — “Long-Term Debt” for additional information. The table below presents an allocation of the purchase price to the net assets acquired based on their fair values at the acquisition date: Identifiable assets acquired and liabilities assumed: Cash $ 194 Land 1,600 Land improvements 3,045 Buildings 7,120 Intangibles 2,580 Tenant improvements 76 Building improvement 29 Other assets 33 Other liabilities (356 ) Total net assets acquired 14,321 Less: Gain on bargain purchase (2,071 ) Purchase price $ 12,250 Pineda Landings With regard to the 90% equity interest in FMKT MGA distributed by FMJV as described in Investment in Unconsolidated Joint Venture The table below presents the fair values of the net assets acquired at the acquisition date: Identifiable assets acquired and liabilities assumed: Cash $ 502 Land 2,857 Land improvements 4,671 Buildings 5,480 Intangibles 2,619 Tenant improvements 403 Building improvement 403 Other property and equipment 17 Other assets 940 Construction loan (8,214 ) Other liabilities (550 ) Total net assets acquired 9,128 Less: Carrying value of 90% equity method investment (2,859 ) Gain on remeasurement of previously held interest (4,005 ) Payable to the 10% joint venture partner (200 ) Cash paid to the 10% joint venture partner $ 2,064 Subsequent to the acquisition date, the Company incurred an impairment loss of $388 in 2016 resulting from the write-down of lease intangibles and other assets associated with the unexpected closure of one tenant’s business at this property. The acquired businesses, in aggregate, contributed $426 of rental income and $460 of net loss to the Company for the period from the acquisition date to December 31, 2016. Pro forma results of operations are not presented as the effects of the acquisition were not material to the Company’s consolidated results of operations.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 8 — Fair Value Measurements The Company records and discloses certain financial assets at their estimated fair value. The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels as follows: Level 1 - Unadjusted quoted prices in active markets for identical assets. Level 2 - Other inputs that are observable for the assets, either directly or indirectly such as quoted prices for identical assets that are not observable throughout the full term of the asset. Level 3 - Inputs that are unobservable. Valuation Methodology Cash and cash equivalents Cash and cash equivalents primarily consist of money-market funds and certificates of deposit maturing within 90 days. Their carrying value approximates fair value due to the short maturity and high liquidity of these funds. Short-term investments Short-term investments consist of certificates of deposit and zero-coupon Fixed-maturity and equity securities Estimated fair values are determined in accordance with U.S. GAAP, using valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Fair values are generally measured using quoted prices in active markets for identical securities or other inputs that are observable either directly or indirectly, such as quoted prices for similar securities. In those instances where observable inputs are not available, fair values are measured using unobservable inputs. Unobservable inputs reflect the Company’s own assumptions about the assumptions that market participants would use in pricing the security and are developed based on the best information available in the circumstances. Fair value estimates derived from unobservable inputs are significantly affected by the assumptions used, including the discount rates and the estimated amounts and timing of future cash flows. The derived fair value estimates cannot be substantiated by comparison to independent markets and are not necessarily indicative of the amounts that would be realized in a current market exchange. The estimated fair values for securities that do not trade on a daily basis are determined by management, utilizing prices obtained from an independent pricing service and information provided by brokers, which are level 2 inputs. Management reviews the assumptions and methods utilized by the pricing service and then compares the relevant data and pricing to broker-provided data. The Company gains assurance of the overall reasonableness and consistent application of the assumptions and methodologies and compliance with accounting standards for fair value determination through ongoing monitoring of the reported fair values. Limited Partnership Investments As described in Note 5 — “Investments” under Limited Partnership Investments Long-term debt The following table summarizes components of the Company’s long-term debt and methods used in estimating their fair values: Maturity Valuation Methodology 3.875% Convertible Senior Notes 2019 Quoted price 4.25% Convertible Senior Notes 2037 Quoted price 3.95% Promissory Note 2020 Discounted cash flow method/Level 3 inputs 4% Promissory Note 2031 Discounted cash flow method/Level 3 inputs 3.75% Callable Promissory Note 2036 Discounted cash flow method/Level 3 inputs 4.55% Promissory Note 2036 Discounted cash flow method/Level 3 inputs Assets Measured at Estimated Fair Value on a Recurring Basis: The following tables present information about the Company’s financial assets measured at estimated fair value on a recurring basis.

Convertible Senior Notes The Company’s Convertible Senior Notes consist of 3.875% Convertible Senior Notes due 2019 (“3.875% Convertible Notes”) and 4.25% Convertible Senior Notes due 2037 (“4.25% Convertible Notes”). The 3.875% Convertible Notes were issued in late 2013 in a private offering for an aggregate principal amount of $103,000. During the first quarter of 2016, the Company repurchased an aggregate of $13,010 in principal, thereby decreasing the aggregate principal balance of its 3.875% Convertible Notes to $89,990. On March 3, 2017, the Company issued 4.25% Convertible Notes in a private offering for an aggregate principal amount of $143,750. The net proceeds of the 4.25% Convertible Notes were $138,775 after $4,975 in related issuance and transaction costs. The following table summarizes Convertible Senior Notes Interest Payment Terms 3.875% Convertible Notes, due March 15, 2019 Semiannually in arrears: March 15 and September 15 4.25% Convertible Notes, due March 1, 2037 Semiannually in arrears: March 1 and September 1 The Convertible Senior Notes rank equally in right of payment to the Company’s existing and future unsecured and unsubordinated obligations. These Convertible Senior Notes do not contain any financial or operating covenants or restrictions on the payments of dividends, the incurrence of indebtedness or the issuance or repurchase of securities by the Company or any of its subsidiaries. The Convertible Senior Notes provide no protection to the note holders in the event of a fundamental change or other corporate transaction involving the Company except those described in each respective indenture. These Convertible Senior Notes do not require a sinking fund to be established for the purpose of redemption. The following table summarizes information regarding the equity and liability components of the Convertible Senior Notes: December 31, 2018 2017 Principal amount $ 233,740 $ 233,740 Unamortized discount (11,316 ) (17,354 ) Liability component – net carrying value before issuance costs $ 222,424 $ 216,386 Equity component – conversion, net of offering costs $ 31,051 $ 31,051 Embedded Conversion Feature The conversion feature of these Convertible Senior Notes is subject to conversion rate adjustments upon the occurrence of specified events (including payment of dividends above a specified amount) but will not be adjusted for any accrued and unpaid interest. 3.875% Convertible Notes 4.25% Convertible Notes The holders of the Convertible Senior Notes may convert all or a portion of their Convertible Senior Notes during specified periods as follows: (1) during any calendar quarter commencing after the calendar quarter ending on the dates specified in each respective indenture, if the last reported sale price of the Company’s common stock for at least 20 trading days during the period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than 130% of the conversion price on each applicable trading day; (2) during the five business-day trading-day The note holders who elect to convert their Convertible Senior Notes in connection with a fundamental change as described in the indentures will be entitled to a “make-whole” adjustment in the form of an increase in the conversion rate. Upon conversion, the Company has options to satisfy its conversion obligation by paying or delivering cash, shares of its common stock or a combination of cash and shares of its common stock. As of December 31, 2018, none of the conditions allowing the holders of either class of the Convertible Senior Notes to convert had been met. The Company determined that the Convertible Senior Notes’ embedded conversion feature is not a derivative financial instrument but rather is required to be separately accounted for in equity because the Company may elect to settle the conversion option entirely or partially in cash. At issuance, the Company accounted for the equity component of the embedded conversion feature as a reduction in the carrying amount of the debt and an increase in additional paid-in Embedded Redemption Feature – Fundamental Change The note holders have the right to require the Company to repurchase for cash all or any portion of the Convertible Senior Notes at par prior to the maturity date should any of the fundamental change events described in the indentures occur. The Company concluded that this embedded redemption feature is not a derivative financial instrument and that it is not probable at issuance that any of the specified fundamental change events will occur. Therefore, this embedded redemption feature is not substantive and will not affect the expected life of the liability component. Embedded Redemption Feature – Put Option of the Note Holder At the option of the holders of the 4.25% Convertible Notes, the Company is required to repurchase for cash all or any portion of the 4.25% Convertible Notes at par on March 1, 2022, March 1, 2027 or March 1, 2032. The Company concluded that this embedded feature is not a derivative financial instrument. In addition, based on economic factors at the time when the 4.25% Convertible Notes were issued, the Company determined it is probable that the note holders will exercise this option. Thus, the Company amortizes the liability component and related issuance costs associated with the 4.25% Convertible Notes over the period from March 3, 2017 to March 1, 2022. The effective interest rates for the 3.875% Convertible Notes and the 4.25% Convertible Notes, taking into account both cash and non-cash 20-year 3.95% Promissory Note On February 27, 2017, the Company converted its outstanding revolving credit facility of $9,441 into a three-year mortgage loan primarily collateralized by a retail shopping center in Melbourne, Florida.

Approximately $50 of principal and interest is payable in 35 monthly installments beginning March 17, 2017 plus a final balloon payment of $8,891 including principal and unpaid interest payable on February 17, 2020 3.75% Promissory Note In connection with the business acquisition described in Note 7 — Business Acquisitions, Sorrento PBX, LLC entered into a 20-year 4% Promissory Note On January 14, 2016, HCPCI Holdings, LLC, a subsidiary of the Company, entered into a 15-year 4.55% Promissory Note On July 6, 2018, Century Park Holdings, LLC, a subsidiary of the Company, entered into a 18-year

For 2018, ceded losses related to Hurricane Irma and Hurricane Michael were $143,890 and $5,230, respectively. For 2017, the reduction in losses and LAE entirely related to Hurricane Irma. During the year ended December 31, 2016, there were no recoveries pertaining to reinsurance contracts that were deducted from losses incurred. At December 31, 2018 and 2017, there were 38 and 37 reinsurers, respectively, participating in the Company’s reinsurance program. Amounts receivable with respect to reinsurers at December 31, 2018 and 2017 were $123,911 and $103,104, respectively. Approximately 29.1% of the reinsurance recoverable balance at December 31, 2018 was concentrated in two reinsurers. Based on the insurance ratings, the payment history and the financial strength of the reinsurers, management believes there was no significant credit risk associated with its reinsurers’ obligations to perform on any prepaid reinsurance contract and to fund any reinsurance recoverable balance as of December 31, 2018. The ratio of assumed premiums earned to net premiums earned for the years ended December 31, 2018, 2017 and 2016 was 0.98%, 4.9%, and 2.5%, respectively. Certain of the reinsurance contracts include retrospective provisions that adjust premiums, increase the amount of future coverage, or result in a profit commission in the event losses are minimal or zero. Due to the losses incurred by Hurricane Irma, the balances of previously accrued benefits and deferred reinsurance premiums were adjusted with the changes recognized in the consolidated statement of income as additional ceded premiums. For the year ended December 31, 2018, the Company recognized a net reduction in ceded premiums of $485 compared with a net increase in ceded premiums of $5,740 for the year ended December 31, 2017. Included in these adjustments attributable to the Company’s contract with Oxbridge for the years ended December 31, 2018 and 2017 were $448 and $933, respectively, of net increase in ceded premiums. These adjustments were reflected as a net reduction in premiums ceded of $12,677 for the year ended December 31, 2016, of which $1,929 related to the Company’s contract with Oxbridge. In addition, adjustments related to retrospective provisions are reflected in other assets. At December 31, 2018 and 2017, other assets included $3,136 and $2,393, respectively, of which $0 and $479 related to the contract with Oxbridge. In June 2016, the Company received a total of $37,800 in cash benefits related to two retrospective reinsurance contracts that terminated May 31, 2016 of which $7,560 was received from Oxbridge. In September 2016, the Company received the final cash payment of $5,716 under the terms of the remaining retrospective reinsurance contract which terminated May 31, 2016. See Note 26 — “Related Party Transaction” regarding the termination of the Company’s reinsurance contract with Oxbridge. Management believes the credit risk associated with the collectability of these accrued benefits is minimal as the amount receivable is concentrated with one reinsurer and the Company monitors the creditworthiness of this reinsurer based on available information about the reinsurer’s financial condition.

Losses and Loss Adjustment Expenses	Note 16 — Losses and Loss Adjustment Expenses The liability for losses and LAE is determined on an individual case basis for all claims reported. The liability also includes amounts for unallocated expenses, anticipated future claim development and losses incurred, but not reported. See Loss and Loss Adjustment Expenses The Company writes insurance primarily in the state of Florida, which could be exposed to hurricanes or other natural catastrophes. The occurrence of a major catastrophe could have a significant effect on the Company’s quarterly results and cause a temporary disruption of the normal operations of the Company. However, the Company is unable to predict the frequency or severity of any such events that may occur in the near term or thereafter. Activity in the liability for losses and LAE is summarized as follows: Years Ended December 31, 2018 2017 2016 Net balance, beginning of year* $ 97,818 $ 70,492 $ 51,690 Incurred, net of reinsurance, related to: Current year 96,860 146,922 104,128 Prior years 12,468 18,707 20,539 Total incurred, net of reinsurance 109,328 165,629 124,667 Paid, net of reinsurance, related to: Current year (54,698 ) (87,770 ) (64,812 ) Prior years (57,622 ) (50,533 ) (41,053 ) Total paid, net of reinsurance (112,320 ) (138,303 ) (105,865 ) Net balance, end of year 94,826 97,818 70,492 Add: reinsurance recoverable 112,760 100,760 — Gross balance, end of year $ 207,586 $ 198,578 $ 70,492 * Net balance represents beginning-of-period beginning-of-period The establishment of loss reserves is an inherently uncertain process and changes in loss reserve estimates are expected as these estimates are subject to the outcome of future events. Changes in estimates, or differences between estimates and amounts ultimately paid, are reflected in the operating results of the period during which such adjustments are adjusted. During the year ended December 31, 2018, the Company incurred approximately $16,520 of net losses related to Hurricane Michael and experienced unfavorable development of $12,468, of which $9,614 $2,101 $144 .

Segment Reporting [Abstract]
Segment Information	Note 17 — Segment Information The Company identifies its operating divisions based on organizational structure and revenue source. Currently, the Company has three reportable segments: insurance operations, real estate operations, and corporate and other. Due to their economic characteristics, the Company’s property and casualty insurance division and reinsurance division are grouped together into one reportable segment under insurance operations. The real estate operations segment includes companies engaged in operating commercial properties the Company owns for investment purposes or for use in its own operations. The corporate and other segment represents the activities of the holding companies, the information technology division, and other companies that do not meet the quantitative thresholds for a reportable segment. The determination of segments may change over time due to changes in operational emphasis, revenues, and results of operations. The Company’s chief executive officer, who serves as the Company’s chief operating decision maker, evaluates each division’s financial and operating performance based on revenue and operating income. For the years ended December 31, 2018, 2017 and 2016, revenues from the Company’s insurance operations before intracompany elimination represented 95.0%, 96.2% and 95.5%, respectively, of total revenues of all operating segments. At December 31, 2018, 2017 and 2016, insurance operations’ total assets represented 85.9%, 87.1% and 87.9%, respectively, of the combined assets of all operating segments. See Note 1 — “Nature of Operations” for a description of the Company’s insurance operations. The following tables present segment information reconciled to the Company’s consolidated statements of income. Intersegment transactions are not eliminated from segment results.

The tax returns filed for the years ending December 31, 2017, 2016, and 2015 remain subject to examination by the Company’s major taxing jurisdictions. The Company elected to classify, if any, interest, and penalties arising from uncertain tax positions as income tax expense as permitted by current accounting standards. There have been no material amounts of interest or penalties for the years ended December 31, 2018, 2017 and 2016. In July 2017, the Company received notice from the Internal Revenue Service stating the Company’s 2015 federal income tax return would be examined. In August 2018, the Internal Revenue Service notified the Company that the examination of the Company’s 2015 federal income tax return was completed with no change to the Company’s reported tax. On December 22, 2017, the Tax Cuts and Jobs Act (the “2017 Tax Act”) was passed and signed into law. Key components of the 2017 Tax Act are: a permanent reduction to the federal corporate income tax rate from a bracket system with a top tax rate of 35% to a flat rate of 21% beginning on January 1, 2018; implementation of a territorial tax system; an amendment to Internal Revenue Code Section 965 that requires U.S. shareholders (10% or greater) of controlled foreign corporations and other specified foreign corporations to include in income, for the last taxable year of such foreign corporation beginning before January 1, 2018, such U.S. shareholder’s pro rata share of a deemed repatriation amount; and changes to carryback and carryforward rules for net operating losses arising after December 31, 2017. Under U.S. GAAP, the tax effects of changes in tax laws or rates need to be recognized in the period in which the law is enacted. For the year ended December 31, 2018, the Company recorded approximately $9,177 of income taxes, which resulted in an effective tax rate of 34.1%. For the year ended December 31, 2017, the Company recorded approximately $8,731 of income tax benefits, which resulted in an effective tax rate of 55.9%. The decrease in the effective tax rate in 2018 as compared with the prior year was primarily attributable to the reduction of the federal corporate income tax rate from 35% to 21%, offset by the negative effect of the derecognition of deferred tax assets of $1,825 for restricted stock awards of which market conditions will not be met prior to their expiry date, the disallowance of the deductibility of the $1,887 expense representing dividends cumulatively paid on such restricted stock awards which were reclassified from retained income (see Restricted Stock Awards Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s net deferred income tax assets are as follows: December 31, 2018 2017 Deferred tax assets: Unearned premiums $ 5,455 $ 5,753 Losses and loss adjustment expenses 3,001 3,154 Stock-based compensation 716 2,455 Net unrealized investment losses 1,641 — Other-than-temporary impairment losses 6 386 Organizational costs 76 90 Accrued expenses 78 — Unearned revenue 231 339 State net operating losses — 333 State capital loss carryforwards — 175 Bad debt reserve 20 2 Other 26 — Total deferred tax assets 11,250 12,687 Deferred tax liabilities: Property and equipment (1,430 ) (1,517 ) Intangible assets (1,841 ) (1,541 ) Deferred policy acquisition costs (4,347 ) (4,365 ) Net unrealized investment gains — (1,907 ) Basis difference related to partnership investments (1,193 ) (599 ) Basis difference related to convertible senior notes (2,429 ) (4,099 ) Prepaid expenses (394 ) (312 ) Accrued expenses — (37 ) Other (684 ) (200 ) Total deferred tax liabilities (12,318 ) (14,577 ) Net deferred tax liabilities $ (1,068 ) $ (1,890 ) State net operating loss carryforwards were fully utilized in 2018 and as such, there are no state net operating loss carryforwards as of December 31, 2018. A valuation allowance is established if, based upon the relevant facts and circumstances, management believes any portion of the deferred tax assets will not be realized. Although realization of deferred income tax assets is not certain, management believes it is more likely than not that deferred tax assets will be realized. Thus, the Company did not have a valuation allowance established as of December 31, 2018 or 2017. The 2017 Tax Act implemented a mandatory one-time one-time one-time one-time

Equity [Abstract]
Stockholders' Equity	Note 20 — Stockholders’ Equity Common Stock In December 2018, the Company’s Board of Directors authorized a plan to repurchase up to $20,000 of the Company’s common shares before commissions and fees. The repurchase plan allows the Company to repurchase shares from time to time through December 31, 2019. The shares may be purchased for cash in open market purchases, block transactions and privately negotiated transactions in accordance with applicable federal securities laws. The share repurchase plan may be modified, suspended, terminated or extended by the Company any time without prior notice. For each of the last two years, the Company’s Board of Directors authorized a one-year Series B Junior Participating Preferred Share Purchase Right On April 18, 2017, the Company’s Board of Directors terminated the Company’s shareholder rights plan by amending the share purchase right’s expiration date to April 18, 2017. Prior to the amended expiration date, one preferred share purchase right entitled a common shareholder to purchase from the Company one one-hundredth one-hundredth Share Repurchase Agreements In conjunction with the issuance of the 4.25% Convertible Notes as described in Note 14 — “Long-Term Debt” under Convertible Senior Notes Prepaid Share Repurchase Forward Contracts The Company has one outstanding prepaid share repurchase forward contract entered into with Societe Generale, a forward counterparty. The Company entered into this forward contract in conjunction with the March 2017 issuance of the 4.25 Convertible Senior Notes $9,400 in exchange for the future delivery of 191,000 shares of the Company’s common stock over a settlement period in 2022. The forward contract is subject to early settlement, in whole or in part, at any time prior to the final settlement date at the option of the forward counterparty, as well as early settlement or settlement with alternative consideration in the event of certain corporate transactions. In the event the Company pays any cash dividends on its common shares, the forward counterparty will pay an equivalent amount to the Company. The shares to be purchased under the forward contract will be treated as retired for financial statement purposes as of the effective date of the forward contract, but will remain outstanding for corporate law purposes, including for purposes of any future stockholders votes. The Company determined that the forward contract does not meet the characteristics of a derivative instrument and, as such, the transaction resulted in an immediate reduction of the outstanding shares used to calculate the weighted-average common shares outstanding for both basic and diluted earnings (loss) per share. In November 2018, the Company’s share repurchase forward contract with Deutsche Bank AG, London Branch, entered into in conjunction with the 2013 issuance of the 3.875 622,751 Preferred Stock Series A Cumulative Convertible Preferred Stock At December 31, 2018 and 2017, there were no Series A Cumulative Convertible Preferred Stock issued or outstanding. Series B Junior Participating Preferred Stock (“Series B Preferred”) At December 31, 2018 and 2017, there were no Series B Preferred issued or outstanding. Undesignated Preferred Stock The Company is authorized to issue up to an additional 18,100,000 shares of preferred stock, no par value. The authorized but unissued and undesignated preferred stock may be issued in one or more series and the shares of each series shall have such rights as determined by the Company’s Board of Directors subject to the rights of the holders of the Series A Cumulative Convertible Preferred Stock and Series B Preferred.

The Company expects to recognize the remaining compensation expense over a weighted-average period of 2.7 years. The following table provides assumptions used in the Black-Scholes option-pricing model to estimate the fair value of the stock options granted during the years ended December 31, 2018 and 2017: 2018 2017 Expected dividend yield 4.00 % 3.53 % Expected volatility 42.22 % 42.86 % Risk-free interest rate 2.57 % 1.92 % Expected life (in years) 5 5 Restricted Stock Awards From time to time, the Company has granted and may grant restricted stock awards to certain executive officers, other employees and nonemployee directors in connection with their service to the Company. The terms of the Company’s outstanding restricted stock grants may include service, performance and market-based conditions. The fair value of the awards with market-based conditions is determined using a Monte Carlo simulation method, which calculates many potential outcomes for an award and then establishes fair value based on the most likely outcome. The determination of fair value with respect to the awards with only performance or service-based conditions is based on the market value of the Company’s stock on the grant date. Information with respect to the activity of unvested restricted stock awards during the years ended December 31, 2018, 2017 and 2016 is as follows: Number of Restricted Stock Awards Weighted Average Grant Date Fair Value Nonvested at January 1, 2016 620,513 $ 30.33 Granted 142,440 $ 32.35 Vested (47,152 ) $ 42.27 Cancelled (160,000 ) $ 26.27 Forfeited (13,298 ) $ 39.06 Nonvested at December 31, 2016 542,503 $ 30.81 Granted 154,936 $ 42.92 Vested (75,983 ) $ 37.95 Forfeited (23,766 ) $ 36.32 Nonvested at December 31, 2017 597,690 $ 32.82 Granted 189,860 $ 41.81 Vested (98,617 ) $ 40.82 Forfeited (56,637 ) $ 36.46 Nonvested at December 31, 2018 632,296 $ 33.33 The Company recognized compensation expense related to restricted stock, which is included in general and administrative personnel expenses, of $ 4,111 4,217 4,198 2.8 2018 2017 2016 Deferred tax benefits recognized $ 862 $ 970 $ 1,619 Tax benefits realized for restricted stock and paid dividends $ 1,086 $ 1,396 $ 140 Fair value of vested restricted stock $ 4,025 $ 2,884 $ 1,993 During 2018, the Company reclassified from retained income dividends of $1,887 cumulatively paid on unvested restricted stock awards with market based vesting conditions to general and administrative personnel expenses for $1,346 and to other operating expenses for $541.

Regulatory Requirements and Res

Regulatory Requirements and Restrictions	12 Months Ended

Text Block [Abstract]
Regulatory Requirements and Restrictions	Note 25 — Regulatory Requirements and Restrictions The Company has no restrictions on the payment of dividends to its shareholders except those restrictions imposed by the Florida Business Corporation Act and those restrictions imposed by insurance statutes and regulations applicable to the Company’s insurance subsidiaries. As of December 2018, without prior regulatory approval, $90,561 of the Company’s consolidated retained earnings was free from restriction under the insurance statutes and regulations and available for the payment of dividends in 2019. The following briefly describes certain related and other requirements and restrictions imposed by the states or jurisdiction in which the Company’s insurance subsidiaries are incorporated. Florida HCPCI and TypTap, which are domiciled in Florida, prepare their statutory financial statements in accordance with accounting principles and practices prescribed or permitted by the Florida Department of Financial Services, Office of Insurance Regulation, which Florida utilizes for determining solvency under the Florida Insurance Code (the “Code”). The commissioner of the FLOIR has the right to permit other practices that may deviate from prescribed practices. Prescribed statutory accounting practices are those practices that are incorporated directly or by reference in state laws, regulations, and general administrative rules applicable to all insurance enterprises domiciled in Florida. Permitted statutory accounting practices encompass all accounting practices that are not prescribed; such practices differ from state to state, may differ from entity to entity within a state, and may change in the future. The Code requires HCPCI to maintain capital and surplus equal to the greater of 10% of their respective liabilities or a statutory minimum as defined in the Code. TypTap, the Company’s insurance subsidiary organized in 2015, is subject to a consent order that requires TypTap to maintain minimum capital and surplus of $20,000 during each of the three years ending December 31, 2016, 2017, and 2018. At December 31, 2018, HCPCI was required to maintain minimum capital and surplus of $21,700. At December 31, 2017, HCPCI was required to maintain minimum capital and surplus of $25,900. HCPCI and TypTap were in compliance with these requirements at December 31, 2018 and 2017. U.S. GAAP differs in certain respects from the accounting practices prescribed or permitted by insurance regulatory authorities (statutory-basis). These entities’ statutory-basis financial statements are presented on the basis of accounting practices prescribed or permitted by the FLOIR. The FLOIR has adopted the National Association of Insurance Commissioner’s (“NAIC”) Accounting Practices and Procedures Manual Since inception, HCPCI and TypTap have each maintained a cash deposit with the Insurance Commissioner of the state of Florida in the amount of $300 to meet regulatory requirements. Under Florida law, a domestic insurer may not pay any dividend or distribute cash or other property to its stockholders except out of that part of its available and accumulated capital and surplus funds which is derived from realized net operating profits on its business and net realized capital gains. A Florida domestic insurer may not make dividend payments or distributions to stockholders without prior approval of the FLOIR if the dividend or distribution would exceed the larger of (1) the lesser of (a) 10.0% of its capital surplus or (b) net income, not including realized capital gains, plus a two year carry forward, (2) 10.0% of capital surplus with dividends payable constrained to unassigned funds minus 25% of unrealized capital gains or (3) the lesser of (a) 10.0% of capital surplus or (b) net investment income plus a three year carry forward with dividends payable constrained to unassigned funds minus 25% of unrealized capital gains. Alternatively, a Florida domestic insurer may pay a dividend or distribution without the prior written approval of the FLOIR if (1) the dividend is equal to or less than the greater of (a) 10.0% of the insurer’s capital surplus as regards to policyholders derived from realized net operating profits on its business and net realized capital gains or (b) the insurer’s entire net operating profits and realized net capital gains derived during the immediately preceding calendar year, (2) the insurer will have policy holder capital surplus equal to or exceeding 115.0% of the minimum required statutory capital surplus after the dividend or distribution, (3) the insurer files a notice of the dividend or distribution with the FLOIR at least ten business days prior to the dividend payment or distribution and (4) the notice includes a certification by an officer of the insurer attesting that, after the payment of the dividend or distribution, the insurer will have at least 115% of required statutory capital surplus as to policyholders. Except as provided above, a Florida domiciled insurer may only pay a dividend or make a distribution (1) subject to prior approval by the FLOIR or (2) 30 days after the FLOIR has received notice of such dividend or distribution and has not disapproved it within such time. As a result, HCPCI was qualified to make dividend payments at December 31, 2018, 2017 and 2016. In addition, Florida property and casualty insurance companies are required to adhere to prescribed premium-to-capital insurance Years Ended December 31, 2018 2017 2016 HCPCI: Gross 2.17 to 1 2.01 to 1 1.81 to 1 Net 1.27 to 1 1.11 to 1 1.07 to 1 TypTap: Gross 0.57 to 1 0.33 to 1 0.09 to 1 Net 0.38 to 1 0.27 to 1 0.07 to 1 Bermuda The Bermuda Monetary Authority requires Claddaugh Casualty Insurance Company, Ltd. (“Claddaugh”), the Company’s Bermuda domiciled reinsurance subsidiary, to maintain minimum capital and surplus of $2,000. At December 31, 2018 and 2017, Claddaugh’s statutory capital and surplus was approximately $45,000 and $63,000, respectively. For the years ended December 31, 2018 and 2017, Claddaugh reported statutory net losses of approximately $8,100 and $5,200, respectively, in contrast with a statutory net profit of approximately $13,200 for the year ended December 31, 2016. During 2018, Claddaugh made a return of capital distribution of $ 10,000 HCPCI and TypTap are subject to risk-based capital (“RBC”) requirements as specified by the NAIC. Under those requirements, the amount of minimum capital and surplus maintained by a property and casualty insurance company is to be determined based on the various risks related to it. Pursuant to the RBC requirements, insurers having less statutory capital than required by the RBC calculation will be subject to varying degrees of regulatory action, depending on the level of capital inadequacy. At December 31, 2018 and 2017, the Company’s insurance subsidiaries individually exceeded any applicable minimum risk-based capital requirements and no corrective actions have been required. As of December 31, 2018, the combined statutory capital and surplus and minimum capital and surplus of the Company’s U.S. insurance subsidiaries were approximately $175,077 and $41,700, respectively. At December 31, 2018 and 2017, restricted net assets represented by the Company’s insurance subsidiaries amounted to $181,571 and $180,286, respectively.

Related Party Transactions	Note 26 — Related Party Transactions Claddaugh had a reinsurance agreement with Oxbridge Reinsurance Limited (“Oxbridge”) whereby a portion of the business assumed from the Company’s insurance subsidiary, HCPCI, was ceded by Claddaugh to Oxbridge. On May 28, 2018, Claddaugh terminated its multi-year reinsurance contract with Oxbridge, effective June 1, 2018. Upon termination, Claddaugh agreed to pay Oxbridge a settlement fee of $600 and derecognized the benefits accrued in connection with retrospective provisions. The settlement fee and the derecognition of the $622 of accrued benefits were recorded in premiums ceded. With respect to the period from June 1, 2016 through May 31, 2017, Oxbridge assumed $6,000 of the total covered exposure for approximately $3,400 in premiums. With respect to the period from June 1, 2017 through May 31, 2018, Oxbridge assumed $7,400 of the total covered exposure for approximately $3,400 in premiums. See Note 15 — “Reinsurance” – which includes the amounts due from and paid by Oxbridge during the years ended December 31, 2017 and 2016 with respect to benefits accrued in connection with the Oxbridge agreements. The premiums charged by Oxbridge were at rates which management believed to be competitive with market rates available to Claddaugh. Oxbridge had deposited funds into trust accounts to satisfy certain collateral requirements under its reinsurance contract with Claddaugh. Trust assets could be withdrawn by Claddaugh, the trust beneficiary, in the event amounts were due under the Oxbridge reinsurance agreement. Among the Oxbridge shareholders are Paresh Patel, the Company’s chief executive officer, who is also chairman of the board of directors for Oxbridge, and members of his immediate family and three of the Company’s non-employee During the first quarter of 2018, the Company purchased six-month During 2016 and January 2017, one of the Company’s directors was a partner at a law firm that performs certain of the Company’s corporate legal matters.

Fees incurred with respect to this law firm for the month ended January 31, 2017 and year ended December 31, 2016 were approximately $6 and $32, respectively. In connection with the acquisition of Pineda Landings described in Note 7 — “Business Acquisition,” the Company incurred and paid $20 of legal fees in 2016 for services provided by a law firm that specializes in real estate transactions at which one immediate family member of the Company’s directors is employed.

Before the adoption of Accounting Standards Update No. 2017-01, in-place in-place in-place After the adoption of Accounting Standards Update No. 2017-01 during the fourth quarter of 2017, the Company evaluates whether substantially all of the fair value of the gross assets acquired in a real estate transaction is concentrated in a single identifiable asset or group of similar identifiable assets. If such concentration is substantial, the transaction is accounted for as an asset acquisition. As a result, the cost of acquiring real estate is allocated to the individual assets based on the relative fair values of the individual assets. Acquisition related costs are capitalized and allocated among the assets acquired.
Cash and Cash Equivalents	Cash and Cash Equivalents.
Available-for-Sale Fixed-Maturity Securities	Available-for-Sale available-for-sale available-for-sale first-in first-out The Company reviews fixed-maturity securities for other-than-temporary impairment on a monthly basis. When the fair value of any investment is lower than its cost, an assessment is made to determine whether the decline is temporary or other-than-temporary. If the decline is determined to be other-than-temporary, the investment is written down to fair value and an impairment loss is recognized in income in the period in which the Company makes such determination. When reviewing impaired securities, the Company considers its ability and intent to hold these securities and whether it is probable that the Company will be required to sell these securities prior to their anticipated recovery or maturity. For the fixed-maturity securities that the Company intends to sell or it is probable that the Company will have to sell before recovery or maturity, the unrealized losses are recognized as other-than-temporary losses in income. In instances where there are credit related losses associated with the impaired fixed-maturity securities for which the Company asserts that it does not have the intent to sell, and it is probable that the Company will not be required to sell until a market price recovery or maturity, the amount of the other-than-temporary impairment loss related to credit losses is recognized in income, and the amount of the other-than-temporary impairment loss related to other non-credit When determining impairment due to a credit related loss, the Company carefully considers factors such as the issuer’s financial ratios and condition, the security’s current ratings and maturity date, and overall market conditions in estimating the cash flows expected to be collected. The expected cash flows discounted at the effective interest rate of the security implicit at the date of acquisition is then compared with the security’s amortized cost at the measurement date. A credit loss is incurred when the present value of the expected cash flows is less than the security’s amortized cost. The Company considers various factors in determining whether an individual security is other-than-temporarily impaired (see Available-for-Sale
Equity Securities	Equity Securities. Equity Securities
Short-Term Investments	Short-Term Investments.
Limited Partnership Investments	Limited Partnership Investments. Limited Partnership Investments The Company generally recognizes its share of the limited partnership’s earnings or losses on a three-month lag. Pursuant to U.S. GAAP, these limited partnerships which are private equity funds must measure their investments at fair value and reflect the unrealized gains and losses in the fair value of their investments on their statement of income. As a result, the carrying value of limited partnership investments at each reporting date approximates their estimated fair value.
Investment in Unconsolidated Joint Venture	Investment in Unconsolidated Joint Venture. When evidence indicates an impairment may occur, the Company evaluates whether a decline in value is other than temporary. Evidence may include continuing operating losses of the joint venture, a declining occupancy rate, a decrease in real estate value, and an oversupply of rental property in close vicinity to the investment property. Should available evidence indicate the recovery of the initial investment is less likely, the Company would compare the carrying value of the investment with its expected residual value and recognize an impairment loss in earnings.
Assets Held for Sale	Assets Held for Sale. In determining the fair value of the assets less costs to sell, the Company primarily relies on the value determined by an independent appraiser. If the estimated fair value less costs to sell is less than the carrying value of the asset, the asset is written down to its estimated fair value less costs to sell and an impairment loss is recognized in the consolidated statement of income. Depreciation is not recorded while assets are classified as held for sale.
Real Estate Investments	Real Estate Investments
Deferred Policy Acquisition Costs	Deferred policy acquisition costs. The method followed in computing DAC limits the amount of such deferred costs to their estimated realizable value, which gives effect to the gross premium earned, related investment income, unpaid losses and loss adjustment expenses and certain other costs expected to be incurred as the premium is earned. DAC is reviewed to determine if it is recoverable from future premium income, including investment income. If such costs are determined to be unrecoverable, they are expensed at the time of determination. The amount of DAC considered recoverable could be reduced in the near term if the estimates of total revenues discussed above are reduced or permanently impaired as a result of the disposition of a line of business. The amount of amortization of DAC could be revised in the near term if any of the estimates discussed above are revised.

Long-Term Debt	Long-Term Debt. To determine the carrying values of the liability and equity components at issuance, the Company measures the fair value of a similar liability, including any embedded features other than the conversion option, and assigns such value to the liability component. The liability component’s fair value is then subtracted from the initial proceeds to determine the carrying value of the debt instrument’s equity component, which is included in additional paid-in Any embedded feature other than the conversion option is evaluated at issuance to determine if it is probable that such embedded feature will be exercised. If the Company concludes that the exercisability of that embedded feature is not probable, the embedded feature is considered to be non-substantive Transaction costs related to issuing a debt instrument that embodies both liability and equity components are allocated to the liability and equity components in proportion to the allocation of the proceeds and accounted for as debt issuance costs and equity issuance costs, respectively. Debt issuance costs are capitalized and presented as a deduction from the carrying value of the debt. Both debt discount and deferred debt issuance costs are amortized to interest expense over the expected life of the debt instrument using the effective interest method. Equity issuance costs are a reduction to the proceeds allocated to the equity component.

Losses and Loss Adjustment Expenses	Losses and Loss Adjustment Expenses. The estimates of unpaid losses and LAE are subject to trends in claim severity and frequency and are continually reviewed. As part of the process, the Company reviews historical data and considers various factors, including known and anticipated regulatory and legal developments, changes in social attitudes, inflation and economic conditions. As experience develops and other data becomes available, these estimates are revised, as required, resulting in increases or decreases to the existing unpaid losses and LAE. Adjustments are reflected in the results of operations in the period in which they are made and the liabilities may deviate substantially from prior estimates. Losses and LAE ceded to or recovered from reinsurers are recorded as a reduction to losses and LAE on the consolidated statement of income.

Income Taxes	Income Taxes. tax-allocation The Company accounts for income taxes in accordance with U.S. GAAP, resulting in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term “more likely than not” means a likelihood of more than fifty percent; the terms “examined” and “upon examination” also include resolution of the related appeals or litigation processes, if any.
