INVESTMENTS Securities Available-for-Sale The amortized cost, gross unrealized gains and losses, and fair value of the Company’s debt securities available-for-sale are as follows for the periods presented: March 31, 2023 Cost or Adjusted / Gross Unrealized Gross Unrealized Fair Value Debt Securities Available-for-sale (In thousands) U.S. government and agency securities (1) $ 104,455 $ 62 $ 3,071 $ 101,446 States, municipalities and political subdivisions 102,209 — 10,604 91,605 Special revenue 281,872 12 28,823 253,061 Industrial and miscellaneous 182,482 173 15,591 167,064 Total $ 671,018 $ 247 $ 58,089 $ 613,176 (1) Includes securities at March 31, 2023 with a carrying amount of $ 23.3 million that were pledged as collateral for the advance agreement entered into with a financial institution in 2018. The Company is permitted to withdraw or exchange any portion of the pledged collateral over the minimum requirement at any time. December 31, 2022 Cost or Adjusted / Gross Unrealized Gross Unrealized Fair Value Debt Securities Available-for-sale (In thousands) U.S. government and agency securities (1) $ 121,811 $ 24 $ 4,093 $ 117,742 States, municipalities and political subdivisions 104,361 — 12,734 91,627 Special revenue 284,946 1 34,817 250,130 Industrial and miscellaneous 194,430 90 18,447 176,073 Total $ 705,548 $ 115 $ 70,091 $ 635,572 (1) Includes securities at December 31, 2022 with a carrying amount of $ 24.3 million that were pledged as collateral for the advance agreement entered into with a financial institution in 2018. The Company is permitted to withdraw or exchange any portion of the pledged collateral over the minimum requirement at any time. The Company’s unrealized losses on corporate bonds have not been recognized because the bonds are of a high credit quality with investment grade ratings. The average rating was an A+ for the three months ended March 31, 2023. The unrealized losses are deemed to be caused by interest rates rising after the bonds were purchased and no credit loss allowance was recorded for the three months ended March 31, 2023 or for the year ended December 31, 2022. Net Realized Gains (Losses) The following table presents net realized gains (losses) on the Company’s debt securities available-for-sale for the three months ended March 31, 2023 and 2022, respectively : 2023 2022 Three Months Ended March 31, Gains Fair Value at Sale Gains Fair Value at Sale (In thousands) Debt Securities Available-for-Sale Total realized gains $ — $ — $ 7 $ 910 Total realized losses ( 2 ) 356 ( 23 ) 1,685 Net realized (losses) gains $ ( 2 ) $ 356 $ ( 16 ) $ 2,595 The following table presents the reconciliation of net realized gains (losses) on the Company’s investments reported for the three months ended March 31, 2023 and 2022, respectively: As of March 31, 2023 2022 Gross realized gains on sales of available-for-sale securities $ — $ 23 Gross realized losses on sales of available-for-sale securities ( 2 ) ( 39 ) Gross realized gains on sale of other investments 1,900 — Net realized gains (losses) $ 1,898 $ ( 16 ) During the first quarter of March 31, 2023, the Company sold its investment in an Insurtech company for $ 4.0 million, resulting in a $ 1.9 million realized gain on the investment. The table below summarizes the Company’s debt securities at March 31, 2023 by contractual maturity periods. Actual results may differ as issuers may have the right to call or prepay obligations, with or without penalties, prior to the contractual maturity of those obligations.

The Company does not intend to sell and it is unlikely the Company will be required to sell the securities prior to their anticipated recovery, and the decline in fair value is deemed due to changes in interest rates and other market conditions. The debt issuers continue to make timely principal and interest payments on the bonds. After taking into account these and other factors previously described, the Company believes these unrealized losses generally were caused by a decrease in market interest rates since the time the securities were purchased and not as a result of credit losses. Quarterly, the Company considers whether it intends to sell an available-for-sale security or if it is more likely than not that it will be required to sell the security before recovery of its amortized costs. In these instances, a decline in fair value is recognized in net income based on the fair value of the security at the time of assessment, resulting in a new cost basis for the security. Other Investments Non-Consolidating Variable Interest Entities (“VIEs”) The Company makes passive investments in limited partnerships (“LPs”), which are accounted for using the equity method, with income reported in earnings. The Company also holds a passive investment in a Real Estate Investment Trust (“REIT”), which is accounted for using the measurement alternative method, and reported at cost less impairment (if any), plus or minus changes from observable price changes. The following table summarizes the carrying value and maximum loss exposure of the Company’s non-consolidated VIEs at March 31, 2023 and December 31, 2022, respectively: As of March 31, 2023 As of December 31, 2022 Carrying Value Maximum Loss Exposure Carrying Value Maximum Loss Exposure Investments in non-consolidated VIEs - Equity method $ 3,416 $ 3,416 $ 3,517 $ 3,517 Investments in non-consolidated VIEs - Amortized cost $ 8,490 $ 8,490 $ 8,490 $ 8,490 Investments in non-consolidated VIEs - Measurement alternative $ 2,377 $ 2,377 $ 4,477 $ 4,477 Total non-consolidated VIEs $ 14,283 $ 14,283 $ 16,484 $ 16,484 No agreements exist requiring the Company to provide additional funding to any of the non-consolidated VIEs in excess of the Company’s initial investment.

Fair Value of Financial Measure

Fair Value of Financial Measurements	3 Months Ended
	Mar. 31, 2023
Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	NOTE 3. FAIR VALUE OF FINANCIAL MEASUREMENTS Fair value is determined based on the exchange price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. The Company is required to use an established hierarchy for fair value measurements based upon the inputs to the valuation and degree to which they are observable or not observable in the market. The three levels in the hierarchy are as follows: • Level 1 – Unadjusted quoted prices are available in active markets for identical assets/liabilities as of the reporting date. • Level 2 – Valuations based on observable inputs, such as quoted prices for similar assets or liabilities at the measurement date; quoted prices in the markets that are not active; or other inputs that are observable, either directly or indirectly. • Level 3 – Pricing inputs are unobservable and significant to the overall fair value measurement, and the determination of fair value requires significant management judgment or estimation. The highest priority is assigned to Level 1 inputs and the lowest priority to Level 3 inputs. At March 31, 2023 and December 31, 2022, there were no transfers in or out of Level 1, 2, and 3. 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. The tables below present the balances of the Company’s invested assets measured at fair value on a recurring basis: March 31, 2023 Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Invested Assets: (in thousands) Debt Securities Available-for-sale U.S. government and agency securities $ 101,446 $ — $ 101,446 $ — States, municipalities and political subdivisions 91,605 — 91,605 — Special revenue 253,061 — 253,061 — Industrial and miscellaneous 167,064 — 167,064 — Total investments $ 613,176 $ — $ 613,176 $ — December 31, 2022 Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Invested Assets: (in thousands) Debt Securities Available-for-sale U.S. government and agency securities $ 117,742 $ — $ 117,742 $ — States, municipalities and political subdivisions 91,627 — 91,627 — Special revenue 250,130 — 250,130 — Industrial and miscellaneous 176,073 — 176,073 — Total investments $ 635,572 $ — $ 635,572 $ — Financial Instruments excluded from the fair value hierarchy The carrying value of premium receivables, accounts payable, accrued expense, revolving loans and borrowings under the Company’s senior secured credit facility approximate their fair value. The rate at which revolving loans and borrowings under the Company’s senior secured credit facility bear interest resets periodically at market interest rates. Non-recurring fair value measurements Assets and liabilities that are measured at fair value on a non-recurring basis include intangible assets 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. For the three months ended March 31, 2023, there were no assets or liabilities that were measured at fair value on a non-recurring basis. Certain of the Company's investments, in accordance with GAAP for the type of investment, are measured using methodologies other than fair value.

Leases [Abstract]
Leases	NOTE 5. 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 the Company’s right-of-use assets and lease obligations. The Company’s 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. Components of the Company’s lease costs were as follows (in thousands): For The Three Months Ended March 31, 2023 2022 Operating lease cost, included in General & Administrative expenses on the Consolidated Statements of Operations $ 393 $ 353 Finance lease cost: Amortization of assets, included in General & Administrative expenses on the Consolidated Statements of Operations 645 646 Interest on lease liabilities, included in Interest expense on the Consolidated Statements of Operations 227 249 Total finance lease cost $ 872 $ 895 Variable lease cost, included in General & Administrative expenses on the Consolidated Statements of Operations $ 409 $ 186 Short-term lease cost, included in General & Administrative expenses on the Consolidated Statements of Operations $ 30 $ 32 Supplemental balance sheet information related to the Company’s operating and financing leases were as follows (in thousands): Operating Leases March 31, 2023 December 31, 2022 Right of use assets $ 7,563 $ 7,335 Lease liability $ 8,890 $ 8,690 Finance Leases Right of use assets $ 19,490 $ 20,132 Lease liability $ 22,012 $ 22,557 Weighted-average remaining lease term and discount rate for the Company’s operating and financing leases for the periods presented below were as follows: Weighted-average remaining lease term March 31, 2023 December 31, 2022 Operating lease 6.31 yrs. 6.49 yrs.

INCOME TAXES For the three months ended March 31, 2023 and 2022, the Company recorded an income tax provision of $ 3.2 million and a tax benefit of $ 10.6 million, respectively, which corresponds to effective tax rates of 18.6 % and 25.7 %, respectively. Effective tax rates are dependent upon components of pre-tax earnings and the related tax effects. The effective tax rate for each period was affected by various permanent tax differences, including disallowed executive compensation deductions which was further limited in 2018 and future years upon the enactment of H.R.1, commonly referred to as the Tax Cuts and Jobs Act (“Tax Act”). Additionally, the state effective income tax rate can also fluctuate as a result of changes in the geographic dispersion of the Company’s business. The effective tax rate can fluctuate throughout the year as estimates used in the tax provision for each quarter are updated as more information becomes available throughout the year. The table below summarizes the significant components of the Company’s net deferred tax assets: March 31, 2023 December 31, 2022 Deferred tax assets: (in thousands) Unearned premiums $ 23,251 $ 17,060 Unearned commission 9,566 10,053 Net operating loss 567 1,189 Tax-related discount on loss reserve 4,705 4,902 Stock-based compensation 386 297 Accrued expenses 997 1,016 Leases 892 885 Unrealized losses 14,131 16,987 Dual Consolidated loss limitation 6,960 9,740 Other 277 238 Total deferred tax asset 61,732 62,367 Valuation allowance ( 4,712 ) ( 6,376 ) Adjusted deferred tax asset 57,020 55,991 Deferred tax liabilities: Deferred acquisition costs $ 23,048 $ 23,420 Prepaid expenses 256 180 Property and equipment 2,358 2,200 Note discount 290 290 Basis in purchased investments 26 28 Basis in purchased intangibles 10,823 11,178 Internal revenue code 481(a) — — Other 2,257 1,854 Total deferred tax liabilities 39,058 39,150 Net deferred tax assets $ 17,962 $ 16,841 The income tax (benefit) expense differs from the amounts computed by applying the U.S. federal income tax rate of as indicated below to pretax income as a result of the following (in thousands): March 31, 2023 March 31, 2022 Change Expected income tax expense at federal rate 21.0 % 21.0 % 0.0 % Tax exempt interest ( 0.3 ) % 0.1 % ( 0.3 ) % Executive compensation 162(m) 0.2 % ( 0.2 ) % 0.4 % Permanent items 1.1 % ( 0.3 ) % 1.4 % State tax expense 5.4 % 2.8 % 2.6 % Prior period adjustment/penalties/interest 0.9 % 0.6 % 0.3 % Valuation allowance ( 9.7 ) % 0.0 % ( 9.7 ) % Non-deductible stock compensation 0.0 % 0.0 % 0.0 % Goodwill impairment 0.0 % 1.7 % ( 1.7 ) % Reported income tax expense 18.6 % 25.7 % ( 7.0 ) % For the quarters ended March 31, 2023 and 2022, the effective tax rate was 18.6 % and 25.7 %, respectively. The 7.0 point change can be attributed to the impact of permanent differences to the pre-tax income or loss. For the quarter ended March 31, 2022, the effective tax rate was impacted primarily by the goodwill impairment and state taxes. For the three months ended March 31, 2023, the effective tax rate was impacted primarily by the valuation allowance that was reduced from $ 6.4 million to $ 4.7 million and state taxes, which had a favorable impact on the effective tax rate for the quarter. The statute of limitations related to the Company’s federal and state income tax returns remains open from the Company’s filings for 2019 through 2022. At March 31, 2023 and December 31, 2022, the Company had no significant uncertain tax positions or unrecognized tax benefits that, if recognized, would impact the effective income tax rate.

Reinsurance

Reinsurance	3 Months Ended
	Mar. 31, 2023
Insurance [Abstract]
Reinsurance	NOTE 12. REINSURANCE Overview In order to limit the Company’s potential exposure to individual risks and catastrophic events, the Company purchases significant reinsurance from third party reinsurers. Purchasing reinsurance is an important part of the Company’s risk strategy, and premiums ceded to reinsurers is one of the Company’s largest costs. The Company has strong relationships with reinsurers, which it attributes to its management’s industry experience, disciplined underwriting, and claims management capabilities. For each of the twelve months beginning June 1, 2021 and 2022, the Company purchased reinsurance from the following sources: (i) the Florida Hurricane Catastrophe Fund, a state-mandated catastrophe fund (“FHCF”) for Florida policies only, (ii) private reinsurers, all of which were rated “A-” or higher by A.M. Best Company, Inc. (“A.M. Best”) or Standard & Poor’s Financial Services LLC (“S&P”) or were fully collateralized, and (iii) the Company’s wholly-owned reinsurance subsidiary, Osprey Re Ltd. (“Osprey Re”). The Company also sponsored catastrophe bonds in 2022 through Citrus Re Ltd. In addition to purchasing excess of loss catastrophe reinsurance, the Company also purchased quota share, property per risk and facultative reinsurance. The Company’s quota share program limits its exposure on catastrophe and non-catastrophe losses and provides ceding commission income. The Company’s per risk programs limit its net exposure in the event of a severe non-catastrophe loss impacting a single location or risk. The Company also utilizes facultative reinsurance to supplement its per risk reinsurance program where the Company capacity needs dictate. Purchasing a sufficient amount of reinsurance to cover catastrophic losses from single or multiple events or significant non-catastrophe losses is an important part of the Company’s risk strategy. Reinsurance involves transferring, or “ceding”, 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 insurance regulators require all insurance companies, like the Company, 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. The Company’s reinsurance program provides reinsurance in excess of its state regulator requirements, which are based on the probable maximum loss that it would incur from an individual catastrophic event estimated to occur once in every 100 years based on its 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. The Company also purchases reinsurance coverage to protect against the potential for multiple catastrophic events occurring in the same year. The Company shares portions of its reinsurance program coverage among its insurance company affiliates. For a detailed discussion of the Company’s 2022-2023 Reinsurance Program please Refer to Part II, Item 8, “Financial Statements and Supplementary Data” and “ Note 12. Reinsurance ” in the Company’s 2022 Form 10-K. Additionally, please refer to Note 17, Commitments and Contingencies, for discussion related to the upcoming commutation of the Company’s 2017 reinsurance contract with the FHCF. Effect of Reinsurance The Company’s reinsurance arrangements had the following effect on certain items in the condensed consolidated statement of income for the three months ended March 31, 2023 and 2022: Three Months Ended March 31, 2023 2022 (In thousands) Premium written: Direct $ 310,309 $ 283,196 Ceded ( 32,776 ) ( 47,131 ) Net $ 277,533 $ 236,065 Premiums earned: Direct $ 317,022 $ 287,368 Ceded ( 150,993 ) ( 134,439 ) Net $ 166,029 $ 152,929 Loss and Loss Adjustment Expenses Direct $ 162,817 $ 199,668 Ceded ( 65,365 ) ( 59,630 ) Net $ 97,452 $ 140,038

Reserve for Unpaid Losses	NOTE 13. 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. The Company estimates its IBNR reserves by projecting its 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: Three Months Ended March 31, 2023 2022 (In thousands) Balance, beginning of period $ 1,131,807 $ 590,166 Less: reinsurance recoverable on unpaid losses 759,682 301,757 Net balance, beginning of period 372,125 288,409 Incurred related to: Current year 98,914 137,626 Prior years ( 1,462 ) 2,412 Total incurred 97,452 140,038 Paid related to: Current year 30,374 39,628 Prior years 78,429 77,136 Total paid 108,803 116,764 Net balance, end of period 360,774 311,683 Plus: reinsurance recoverable on unpaid losses 620,218 276,737 Balance, end of period $ 980,992 $ 588,420 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. As of March 31, 2023, the Company reported $ 360.8 million in unpaid losses and loss adjustment expenses, net of reinsurance which included $ 284.0 million attributable to IBNR net of reinsurance recoverable, or 78.7 % of net reserves for unpaid losses and loss adjustment expenses. Reinsurance recoverable on unpaid losses includes expected reinsurance recoveries associated with reinsurance contracts the Company has in place. The amount may include recoveries from catastrophe excess of loss reinsurance, net quota share reinsurance, per risk reinsurance, and facultative reinsurance contracts.

Long-Term Debt	NOTE 14. 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. Interest is payable semi-annually in arrears, on February 1, and August 1 of each year. As of March 31, 2023, pursuant to the guidance of ASU 2020-06, the outstanding Convertible Notes would have been converted into 59,263 shares of the Company's common stock as they are dilutive and as such have been included in the Company's quarterly diluted earnings per share results. For the three months ended March 31, 2022, the Company was in a net loss position, therefore the diluted earnings per share would not be considered for the conversion as the Convertible Notes were anti-dilutive for that period. As of March 31, 2023, the Company had approximately $ 885,000 of the Convertible Notes outstanding, net of $ 21.1 million of Convertible Notes held by an insurance company subsidiary. For each of the three-month periods ended March 31, 2023 and 2022, the Company made interest payments, net of affiliated Convertible Notes, of approximately $ 26,000 and $ 630,650 , on the outstanding Convertible Notes, respectively. In January 2022, the Company reacquired and retired $ 11.7 million of its outstanding Convertible Senior Notes. Payment was made in cash and the Convertible Notes were retired at the time of repurchase. In addition, the Company expensed $ 242,700 which was the proportionate amount of the unamortized issuance and debt discount costs associated with this repurchase. Senior Secured Credit Facility The Company is party to a credit agreement dated as of December 14, 2018 (as amended from time to time, the “Credit Agreement”) with a syndicate of lenders. The Credit Agreement, as amended, provides for (1) a five-year senior secured term loan facility in an aggregate principal amount of $ 100 million (the “Term Loan Facility”) and (2) a five-year senior secured revolving credit facility in an aggregate principal amount of $ 50 million (inclusive of a sublimit for the issuance of letters of credit equal to the unused amount of the revolving credit facility and a sublimit for swingline loans equal to the lesser of $ 25 million and the unused amount of the 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, which began with the close of the fiscal quarter ending March 31, 2019, in an amount equal to $ 1.9 million per quarter, payable quarterly, decreasing to $ 875,000 per quarter commencing with the quarter ending December 31, 2021, and increasing to $ 2.4 million per quarter commencing with the quarter ending December 31, 2022, with the remaining balance payable at maturity. The Term Loan Facility matures on July 28, 2026 . As of March 31, 2023, there was $ 86.8 million in aggregate principal outstanding under the Term Loan Facility and after giving effect to the additional term loan advance that was used to refinance amounts outstanding under the Revolving Credit Facility and to pay fees, costs and expenses related thereto, there was $ 10 million in aggregate principal outstanding under the Revolving Credit Facility. For the three months ended March 31, 2023 and 2022, the Company made principal and interest payments of approximately $ 4.1 million and $ 2.6 million, respectively, on the Term Loan Facility. Revolving Credit Facility: The Revolving Credit Facility allows for borrowings of up to $ 50 million inclusive of a sublimit for the issuance of letters of credit equal to the unused amount of the Revolving Credit Facility and a sublimit for swingline loans equal to the lesser of $ 25 million and the unused amount of the Revolving Credit Facility. As of December 31, 2022, we had $ 10.0 million in borrowings and $ 32.6 million letters of credit outstanding under the Revolving Credit Facility. In connection with the incurrence of additional amounts under the Term Loan Facility pursuant to a November 2022 amendment to the Credit Agreement, the borrowings under the Revolving Credit Facility were repaid in full. On December 23, 2022, the Company drew $ 10 million from the amended Revolving Credit Facility, resulting in an outstanding principal balance under the Revolving Credit Facility in the amount of $ 10 million. At December 31, 2022, the Company had multiple letters of credit that total $ 32.6 million outstanding under the Revolving Credit Facility. At January 31, 2023 , $ 22.6 million of the letters of credit were terminated and at March 31, 2023, there remained a single letter of credit in the amount of $ 10 million and $10 million outstanding under the Revolving Credit Facility. For the three months ended March 31, 2023, the Company made interest payments in aggregate of approximately $ 188,670 on the Revolving Credit Facility. At the Company's option, borrowings under the Credit Facilities bear interest at rates equal to either (1) a rate determined by reference to SOFR, plus an applicable margin and a credit adjustment spread equal to 0.10 % or (2) a base rate determined by reference to the highest of (a) the “prime rate” of Regions Bank, (b) the federal funds rate plus 0.50 %, and (c) the adjusted term SOFR in effect on such day for an interest period of one month plus 1.00 %, plus an applicable margin. At March 31 2023, the effective interest rate on for the Term Loan Facility and Revolving Credit Facility was 7.884 % and 7.661 %, respectively. 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. 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 . Pursuant to the terms of the mortgage loan, on October 30, 2022, the interest rate adjusted 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 %, which resulted in an increase of the rate from 4.95 % to 7.42 % per annum. The Company makes monthly principal and interest payments against the loan. For each of the three months ended March 31, 2023 and 2022, the Company made principal and interest payments of $ 223,212 on the mortgage loan, respectively. FHLB Loan Agreements In December 2018, a subsidiary of the Company received a 3.094 % fixed interest rate cash loan of $ 19.2 million from the Federal Home Loan Bank (“FHLB”) Atlanta. In connection with the loan agreement, the subsidiary became a member of the 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 the acquired FHLB common stock and certain other investments to be pledged as collateral. As of March 31, 2023, the fair value of the collateralized securities was $ 22.2 million and the equity investment in FHLB common stock was $ 1.2 million. For the three months ended March 31, 2023, and 2022, the Company made quarterly interest payments as per the terms of the loan agreement of approximately $ 148,500 and $ 150,160 , respectively.

The Company’s ability to secure future debt financing depends, in part, on its ability to remain in such compliance. The covenants in the Credit Agreement may limit the Company’s flexibility in connection with future financing transactions and in the allocation of capital in the future, including the Company’s ability to pay dividends and make stock repurchases, and contribute capital to its insurance subsidiaries that are not parties to the Credit Agreement.

Insurance [Abstract]
Statutory Accounting and Regulations	NOTE 16. STATUTORY ACCOUNTING AND REGULATIONS State laws and regulations, as well as national regulatory agency requirements, govern the operations of all insurers such as the Company’s 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 Heritage Property & Casualty Insurance Company (“Heritage P&C)”, Narragansett Bay Insurance Company (“NBIC”), Zephyr Insurance Company (“Zephyr”), and Pawtucket Insurance Company (“PIC”) 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 $ 15.0 million or 10 % of its 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, Zephyr, and NBIC was $ 260.5 million at March 31, 2023 and $ 276.3 million at December 31, 2022. State law also requires the Company’s insurance subsidiaries to adhere to prescribed premium-to-capital surplus ratios, and risk-based capital requirements with which the Company's insurance subsidiaries are in compliance. At March 31, 2023, the Company’s insurance subsidiaries met the financial and regulatory requirements of each of the states in which they conduct business.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 17. COMMITMENTS AND CONTINGENCIES The Company is involved in claims-related legal actions arising in the ordinary course of business. The Company accrues amounts resulting from claims-related legal actions in unpaid losses and loss adjustment expenses during the period that it determines an unfavorable outcome becomes probable and it can estimate the amounts. Management makes revisions to its estimates based on its analysis of subsequent information that the Company receives regarding various factors, including: (i) per claim information; (ii) company and industry historical loss experience; (iii) judicial decisions and legal developments in the awarding of damages; and (iv) trends in general economic conditions, including the effects of inflation. The Company’s Florida insurance company affiliate is required to enter into a reinsurance contract with the FHCF for a portion of its catastrophe risk transfer each year. Since the Company’s inception in 2012, few catastrophic events have resulted in losses which pierced the FHCF layer and resulted in reimbursements from the FHCF. To date, losses from only Hurricane Irma, which struck in 2017, and Hurricane Ian, which struck in 2022, have triggered the Company’s FHCF coverage. The Company’s 2017 reinsurance agreement with the FHCF is consistent among Florida insurance companies and requires a commutation no later than 60 months after the end of the contract year, which the commutation process is expected to begin in June 2023. This commutation represents an agreement between Heritage and the FHCF to terminate the 2017 reinsurance agreement and agree on the conditions under which all obligations for both parties are discharged. The terms of the 2017 reinsurance agreement with the FHCF provide for the commutation process as well as the process to settle any disagreements as to the present value of outstanding losses that will serve as the basis for determining the amount payable by FHCF upon termination of the reinsurance agreement. The commutation process has not yet begun, and the Company cannot predict whether the loss estimates determined by Heritage and the loss estimates determined by the FHCF will differ. As such, there is no assurance that the reported reinsurance recoverable for Hurricane Irma losses from the FHCF will differ from the final amount that will be paid by the FHCF. Further, social inflation and the litigated claims environment in the State of Florida, which affected Hurricane Irma claims could result in adverse development of these claims, which create uncertainty as to the ultimate cost to settle the remaining Hurricane Irma claims. Accordingly, the final amount that will be paid by the FHCF could vary from the Com pany’s current or future estimation of losses to be recovered from the FHCF. The commutation process will be final and binding on both parties once complete.
