Summary of Significant Accounting Policies (Policies)	12 Months Ended
Dec. 31, 2023
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation. The accompanying financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”).
Principles of Consolidation	Principles of Consolidation. The accompanying consolidated financial statements include the accounts of HCI Group, Inc. and its majority-owned and controlled subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. In addition, the Company evaluates its relationships or investments for consolidation pursuant to authoritative accounting guidance related to the consolidation of variable interest entities under the Variable Interest Model prescribed by the Financial Accounting Standards Board (“FASB”). A variable interest entity is consolidated when the Company has the power to direct activities that most significantly impact the economic performance of the variable interest entity and has the obligation to absorb losses or the right to receive benefits from the variable interest entity that could potentially be significant to the variable interest entity. When a variable interest entity is not consolidated, the Company uses the equity method to account for the investment. Under this method, the carrying value is generally the Company’s share of the net asset value of the unconsolidated entity, and changes in the Company’s share of the net asset value are recorded in net investment income.
Use of Estimates	Use of Estimates. The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as well as the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ materially from these estimates. Material estimates that are particularly susceptible to significant change in the near term are primarily related to losses and loss adjustment expenses, reinsurance with retrospective provisions, reinsurance recoverable, deferred income taxes, limited partnership investments, intangible assets acquired from United, allowance for credit losses, and stock-based compensation expense.
Cash and Cash Equivalents	Cash and Cash Equivalents. The Company considers all short-term highly liquid investments with original maturities of less than three months to be cash and cash equivalents. At December 31, 2023 and 2022, cash and cash equivalents consisted of cash on deposit with financial institutions and securities brokerage firms, and certificates of deposit.
Restricted Cash	Restricted Cash. Restricted cash represents funds in the Company’s sole ownership held by certain states in which the Company’s insurance subsidiaries conduct business to meet regulatory requirements and not available for immediate business use. Funds withheld in an account for which the Company is a co-owner but not the named beneficiary are not considered restricted cash and are included in funds withheld for assumed business on the consolidated balance sheets.
Available-for-Sale Fixed-Maturity Securities	Available-for-Sale Fixed-Maturity Securities. Fixed-maturity securities that are available for sale include debt securities and redeemable preferred stock. The Company’s available-for-sale securities are carried at fair value. Changes in the fair value of available-for-sale securities representing unrealized gains or losses, other than credit losses, are excluded from net investment income and reported in stockholders’ equity as a component of accumulated other comprehensive income (loss), net of deferred income taxes. Realized investment gains and losses from sales are recorded on the trade date and are determined using the first-in first-out (“FIFO”) method. Investment income is recognized as earned and discounts or premiums arising from the purchase of debt securities are recognized in investment income using the interest method over the estimated remaining term of the security. Gains and losses from call redemptions and repayments are charged to investment income. The Company reviews fixed-maturity securities for impairment on a monthly basis. 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 impairment losses in income. Impaired securities where the Company has the ability and intent to hold until recovery and believes it is not probable that the Company will be required to sell these securities prior to their anticipated recovery or maturity, are evaluated for the existence of credit-related losses. 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, the failure of the issuer to make a scheduled payment, 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 are 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. If such credit-related losses exist, an allowance for credit losses is established with a charge in the consolidated statement of income. Subsequent changes in the allowance, whether favorable or unfavorable, are recorded on the consolidated statement of income. See additional information in the Allowance for Credit Losses section within this note. Any remaining impairment loss related to other non-credit factors such as changes in interest rates or market conditions is reflected as a component of accumulated other comprehensive income (loss).
Allowance for Credit Losses	Allowance for Credit Losses. Allowance for credit losses represents an estimation of potential losses that the Company may experience due to credit risk. The allowance for credit losses account is a contra account of a financial asset to reflect the net amount expected to be collected. Any increase or decrease in the allowance for credit losses related to investments is recognized and reflected as credit losses on investments in the Company’s consolidated statement of income. For all other financial assets, credit loss expense is included in other operating expenses. When the risk of credit loss becomes certain, the allowance for credit losses account will be written off against the financial asset. Under the Current Expected Credit Loss (“CECL”) model, the Company measures all expected credit losses related to relevant financial assets based on historical experience, current conditions, and reasonable and supportable forecasts which incorporate forward-looking information. The Company primarily uses a discounted cash flow method and a rating-based method in estimating credit losses at a reporting date for financial assets under the scope of the CECL model. The discounted cash flow method is a valuation method used to estimate the value of a financial asset based on its future cash flows. The Company uses this method to determine the expected credit losses for available-for-sale fixed-maturity securities. In addition, the Company elected not to measure an allowance for credit losses for accrued interest receivable as any uncollectible amount is adjusted to interest income on a monthly basis. At present, the exposure to credit losses for certain financial assets related to non-insurance business is considered immaterial to the Company’s financial position. For certain financial assets related to insurance business such as reinsurance recoverable and reinsurance receivable for premium refund, the Company uses a rating-based method, which is a modified version of the probability of default method. It requires two key inputs: a) the liquidation rate and b) the amount of loss exposure. The liquidation rate, which is published annually, is the ratio of impaired insurance companies that were eventually liquidated to the group of insurance companies considered by A.M. Best in its study. The amount of loss exposure represents the future billing balance, net of any collateral, spread over the projected periods that are based on the Company’s historical claim payment pattern. The rating-based method measures credit losses by multiplying the future billings grouped by insurance rating over the projected periods by their corresponding liquidation rates by insurance rating. For paid reinsurance recoverable which is due within 90 days after billing, the Company will rely heavily on each reinsurer’s credit rating, recent financial condition, and historical collection problems, if any, in determining the expected credit loss. For risk attributable to disagreements between an insurer and reinsurer regarding a difference in interpretation of provisions in a reinsurance agreement (“dispute risk”), the Company will continue to use an incurred loss method to estimate losses. At December 31, 2023, there was no dispute risk associated with the reinsurance recoverable balance.
Equity Securities	Equity Securities. Equity securities represent ownership interests held by the Company in entities for investment purposes. Unrealized holding gains and losses related to equity securities are reported in the consolidated statements of income as net unrealized investment gains and losses. Realized investment gains and losses from sales are recorded on the trade date and are determined using the FIFO method (see b) Equity Securities in Note 5 -- “Investments”).
Limited Partnership Investments	Limited Partnership Investments. The Company has interests in limited partnerships that are not registered under the United States Securities Act of 1933, as amended, the securities laws of any state or the securities laws of any other jurisdictions. The partnership interests cannot be resold in the public market and any withdrawal is subject to the terms and conditions of the partnership agreements. The Company has no influence over partnership operating and financial policies. The Company uses the equity method to account for the investments with ownership interest greater than five percent. For the investments with ownership interest at five percent or less, the Company uses the net asset value method to estimate the fair value of these investments. The Company generally recognizes its share of the limited partnerships’ earnings or losses on a three-month lag. Due to the lag, the Company may record an adjustment to the Company’s most recent share of net asset value when the amount can be reasonably estimated and a significant adverse impact on the net asset value is expected as a result of a major economic event. Net investment income or loss from limited partnerships represents a net aggregate amount of operating results allocated to the Company based on the percentage of ownership interest in each limited partnership. 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 statements 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. The Company had a 90% equity interest in a limited liability company (treated as a joint venture under U.S. GAAP) that owned land for lease or for sale. The joint venture was determined to be a variable interest entity as it lacked sufficient equity to finance its activities without additional subordinated financial support. Despite having a majority equity interest, the Company did not have the power to direct the activities that most significantly impact the economic performance of the joint venture and, accordingly, was not required to consolidate the joint venture as its primary beneficiary. As a result, the Company used the equity method to account for this investment.
Real Estate Investments	Real Estate Investments. Real estate investments include real estate and the related assets purchased for investment purposes (see Note 5 -- “Investments”). Real estate and the related depreciable assets are carried at cost, net of accumulated depreciation, which is included in net investment income and allocated over the estimated useful life of the asset using the straight-line method of depreciation. Land is not depreciated. Real estate is evaluated for impairment when events or circumstances indicate the carrying value of the real estate may not be recoverable.
Deferred Policy Acquisition Costs	Deferred Policy Acquisition Costs. Deferred policy acquisition costs (“DAC”) represent direct costs to acquire insurance contracts and consist of premium taxes, inspection fees and commissions paid to outside agents at the time of collection of the policy premium. DAC may also include expenses associated with the transition of policies from other insurers for replacement policies and the issuance of renewal policies under the Company’s own rates and terms. DAC is amortized over the life of the related policy in relation to the amount of gross premiums earned. Ceding commission and related costs paid associated with assumed business are also deferred and amortized over the life of the reinsurance agreement. 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 gross premium earned 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 gross premium earned estimates discussed above are revised.
Property and Equipment	Property and Equipment. Property and equipment is stated at cost less accumulated depreciation and amortization, which is included in other operating expenses. Depreciation is calculated on a straight-line basis over the estimated useful lives as follows: land improvements, five years; building, 39 years; building improvements, three to ten years; computer hardware and software, three years; and furniture and office equipment, three to seven years. Leasehold improvements are amortized over the shorter of the lease term or the asset’s useful life. Land is not depreciated. Expenditures for improvements are capitalized to the property accounts. Replacements and maintenance and repairs that do not improve or extend the life of the respective assets are expensed as incurred. The Company capitalizes both internal and external costs for internally developed software during the application development stage. During the preliminary project and post-implementation stage, internal-use software development costs are expensed as incurred. Capitalized software costs are depreciated on a straight-line basis over the estimated useful life of seven years.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets. Long-lived assets, such as property and equipment, are reviewed for impairment annually or whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. The Company assesses the recoverability of long-lived assets by determining whether the assets can be recovered from undiscounted future cash flows. Recoverability of long-lived assets is dependent upon, among other things, the Company’s ability to maintain profitability so as to be able to meet its obligations when they become due. In our opinion, based upon current information and projections, tangible long-lived assets will be recovered over the period of benefit.
Leases	Leases. The Company leases office equipment, storage units, and office space from non-affiliates under terms ranging from one month up to nine years. In assessing whether a contract is or contains a lease, the Company first determines whether there is an identified asset in the contract. The Company then determines whether the contract conveys the right to obtain substantially all of the economic benefits from use of the identified asset or the right to direct the use of the identified asset. The Company elects not to record any lease with a term of 12 months or less on the consolidated balance sheet. For such short-term leases, the Company recognizes the lease payments in expense on a straight-line basis over the lease term. If the contract is or contains a lease and the Company has the right to control the use of the identified asset, the right-of-use (“ROU”) asset and the lease liability is measured from the lease component of the contract and recognized on the consolidated balance sheet. In measuring the lease liability, the Company uses its incremental borrowing rate for a loan secured by a similar asset that has a term similar to the lease term to discount the lease payments. The contract is further evaluated to determine the classification of the lease as to whether it is finance or operating. If the lease is a finance lease, the ROU asset is depreciated to depreciation expense over the shorter of the useful life of the asset or the lease term. Interest expense is recorded in connection with the lease liability using the effective interest method. If the lease is an operating lease, the ROU asset is amortized to lease expense on a straight-line basis over the lease term. For the presentation of finance leases on the Company’s consolidated balance sheets, ROU assets and corresponding lease liabilities are included with property and equipment, net, and long-term debt, respectively. For the presentation of operating leases on the Company’s consolidated balance sheets, ROU assets are presented as right-of-use assets - operating leases and corresponding lease liabilities are reflected as lease liabilities - operating leases.
Lessor Leases	The Company as a lessor leases its commercial and retail properties, boat slips, and docks to non-affiliates at various terms. If the contract gives the Company’s customer the right to control the use of the identified asset, revenue is recognized on a straight-line basis over the lease term. Initial direct costs incurred by the Company are deferred and amortized on a straight-line basis over the lease term. The Company also records an unbilled receivable, which is the amount by which straight-line revenue exceeds the amount billed in accordance with the lease.
Intangible Assets	Intangible Assets. Intangibles related to real estate investments consist of the value attributable to the acquired in-place leases and the primary, or anchor tenant relationships. The value attributable to the anchor tenant relationship represents the economic benefits of having a nationally recognized retailer as the lead tenant, which draws consumer traffic and other tenants to the retail center. These intangibles are amortized to expense over the related lease term. Amortization of the intangibles related to real estate investments is reflected in net investment income in the consolidated statements of income. The Company reviews these intangible assets for impairment annually or when events or changes in circumstances indicate the carrying value may not be recoverable. In the event the Company determines the carrying value is not recoverable, an impairment loss is recorded in the Company’s consolidated statements of income. Acquired intangible assets represent the fair value of consideration the Company paid and is estimated to pay in exchange for the renewal rights and non-compete intangible assets acquired from the seller. In the renewal rights transactions, the Company purchased the right, but not the obligation, to offer homeowners insurance coverage to all policyholders of the seller in certain states on the agreed-upon policy replacement date. The renewal rights agreements also contain a non-compete clause whereby the seller agrees not to offer homeowners insurance policies in these states through a specified date. The Company records these intangible assets based on the fair value of the consideration it paid and is estimated to pay to the seller as provided in the renewal rights agreements with the seller. The Company engaged a third-party valuation specialist to assist with the allocation of the renewal rights and non-compete intangible assets acquired. Intangible assets are amortized over their estimated useful lives. Amortization of the renewal rights and non-compete intangible assets is reflected in other operating expenses in the consolidated statements of income. Intangible assets are evaluated to ensure that there is no impairment to carrying value and no change required in the amortization period. See Note 10 -- “Intangible Assets, Net” for additional information.
Funds Withheld for Assumed Business	Funds Withheld for Assumed Business. Pursuant to the Company’s quota share reinsurance agreements with United, trust accounts were established for the benefit of United as beneficiary. The trust balances represent the net amount owed to the Company under the reinsurance agreements. The trusts consist of a) funds deposited to establish the accounts and b) premiums, including any subsequent premium adjustment, and are reduced by commissions and paid losses and loss adjustment expenses. The assets within the trust accounts consist primarily of cash. Funds remaining at the completion of the quota share agreements are to be distributed according to the trust agreements. Prior to United being placed into receivership by the State of Florida on February 27, 2023, United had the exclusive and unconditional right to withdraw funds from the trust accounts on demand with written notice in compliance with the quota share reinsurance agreements. The funds are now under the control of the receiver.
Lease Acquisition Costs	Lease Acquisition Costs. Lease acquisition costs represent capitalized costs of finding and acquiring tenants such as leasing commissions, legal, and marketing expenses. The costs are included in other assets on the consolidated balance sheets. The Company amortizes these costs in other operating expenses on a straight-line basis over the term of a lease.
Long-Term Debt	Long-Term Debt. Long-term debt includes debt instruments and finance lease obligations. A debt instrument is generally classified as a liability and carried at amortized cost, net of any issuance costs. Debt issuance costs are capitalized and amortized to interest expense over the expected life of the debt instrument using the effective interest method. At issuance, a debt instrument with embedded features such as conversion and redemption options is evaluated to determine whether bifurcation and derivative accounting is applicable. 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 and would not impact the initial measurement and expected life of the debt instrument.
Redeemable Noncontrolling Interest	Redeemable Noncontrolling Interest. Redeemable noncontrolling interest represents an economic interest in TTIG and is presented in the temporary equity (mezzanine) section of the consolidated balance sheets. The interest contains rights in dividends, voting, conversion, participation, liquidation preference and redemption. The redemption feature is not solely within the control of TTIG. The redeemable noncontrolling interest is initially recorded at fair value and is decreased by related issuance costs. The fair value is estimated using a residual fair value approach. The effect of increasing dividend rates is accreted to the redeemable noncontrolling interest with a corresponding reduction in retained income. The effective interest method is used for accretion over the period of the increasing dividend rates. The carrying value of the interest is also subsequently adjusted for accrued dividends and dividend payments. The Company has an option to pay the dividends in cash or make a payment-in-kind. The dividends are accrued monthly assuming that they will be settled in cash. When the redeemable noncontrolling interest is probable of becoming redeemable, the Company elects to recognize changes in the redemption value immediately as it occurs and adjust the carrying value of the interest to the maximum redemption value which is the higher of the redemption price or fair market value at the reporting date. Such changes in the redemption value are treated as dividends when calculating income available to common stockholders.
Noncontrolling Interests	Noncontrolling Interests. The Company has noncontrolling interests attributable to TTIG. A noncontrolling interest arises when the Company has less than 100% of the voting rights and economic interests in a subsidiary. The noncontrolling interest is periodically adjusted for the expensing of TTIG’s stock-based awards granted to its employees, the interest’s share of TTIG’s net income or loss to common stockholders and change in other comprehensive income or loss.
Prepaid Share Repurchase Forward Contract	Prepaid Share Repurchase Forward Contract. A prepaid share repurchase forward contract is generally a contract that allows the Company to buy from a counterparty a specified number of common shares at a specific time at a given forward price. The Company entered into such a contract and evaluated the characteristics of the forward contract to determine whether it met the definition of a derivative financial instrument pursuant to U.S. GAAP. The Company determined the forward contract was an equity contract on the Company’s common shares requiring physical settlement in common shares of the Company. As such, the transaction was recognized as a component of stockholders’ equity with a charge to additional paid-in capital equal to the prepayment amount, which represents the cash paid to the counterparty. There was no recognition in earnings for changes in fair value in subsequent periods.
Losses and Loss Adjustment Expenses	Losses and Loss Adjustment Expenses. Reserves for losses and loss adjustment expenses (“LAE”) are determined by establishing liabilities in amounts estimated to cover incurred losses and LAE. Such reserves are determined based on the assessment of claims reported and the development of pending claims. These reserves are based on individual case estimates for the reported losses and LAE and estimates of such amounts that are incurred but not reported. Changes in the estimated liability are charged or credited to income as the losses and LAE are settled. 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 statements of income.
Advance Premiums	Advance Premiums. Premium payments received prior to the policy effective date are recorded as advance premiums. Once the policy is in force, the premiums are recorded as described under “Premium Revenue” below.
Premiums Receivable	Premiums Receivable. Premiums receivable represent the amount of premiums due from policyholders for insurance coverage. Premiums are recorded as receivable in the Company’s general ledger on the effective date of the policy. Premiums are billed to the policyholder 45-60 days in advance of the effective date. The policyholder is given a 30-day grace period after the effective date to pay the premium before the insurance coverage is cancelled. If the policyholder does not pay the premium, the Company can cancel the policy and has no obligation to provide insurance coverage. Unpaid renewal policies are cancelled at midnight on the last day of the period for which the policyholder has paid. The unearned premium liability for the cancelled policy is reversed along with the premium receivable balance. Therefore, there is no unpaid earned premium and credit loss associated with the cancelled policy. However, when the 30-day grace period falls between two reporting periods, the premium receivable balance at the end of the first reporting period may potentially be overstated for not considering the policy that is subsequently cancelled during the following reporting period. To mitigate the overstatement issue, the Company estimates the monetary impact from the subsequent policy cancellation by multiplying the historical cancellation rate to the premiums receivable balance at the reporting date. An allowance for uncollectible premiums, which offsets the balance of premiums receivable, is established by reducing the unearned premiums liability and earned revenues. At December 31, 2023 and 2022, allowances for uncollectible premiums were $3,152 and $5,362, respectively. The decrease in allowances for uncollectible premiums during 2023 resulted in a $2,113 increase in unearned premiums during the year ended December 31, 2023. The increase in allowances for uncollectible premiums during 2022 resulted in a $3,432 decrease in unearned premiums during the year ended December 31, 2022. For the year ended December 31, 2023, an increase in earned revenues was $97 as opposed to decreases in earned revenues of $180 and $15 for the years ended December 31, 2022 and 2021, respectively.
Reinsurance	Reinsurance Ceded. In the normal course of business, the Company seeks to reduce the loss that may arise from catastrophes or other events by reinsuring certain levels of risk in various areas of exposure with other insurance enterprises or reinsurers. The Company contracts with a number of reinsurers to secure its annual reinsurance coverage, which generally becomes effective June 1st of each year. The Company purchases reinsurance each year taking into consideration probable maximum losses and reinsurance market conditions. Amounts recoverable from reinsurers are estimated in a manner consistent with the applicable reinsurance contract or contracts. Premiums ceded to other companies have been reported as a reduction of gross premiums earned to arrive at net premiums earned. Prepaid reinsurance premiums represent the unexpired portion of premiums ceded to reinsurers. From time to time, the Company may elect to pay a reinstatement premium to a reinsurer in order to restore an amount of reinsurance coverage limit exhausted by a loss event. When that occurs, the unamortized portion of the existing prepaid reinsurance premium associated with the first coverage limit will be immediately expensed. The reinstatement premium will be recognized as prepaid reinsurance premium which will be amortized to premiums ceded over the remaining coverage period of a contract. One of the Company’s current reinsurance contracts contains retrospective provisions including terms and conditions that adjust premiums based on the loss experience under the contract. In such cases, a with-and-without method is used to estimate the asset or liability amount to be recognized at each reporting date. The amount of the estimate is the difference between the net contract costs before and after the loss experience under the contract. Estimates related to premium adjustments are recognized in ceded premiums earned. These estimates are reviewed monthly based on the loss experience to date and as adjustments become necessary. Such adjustments in premiums ceded are reflected in the Company’s current operations and recorded in other assets until received upon the expiration of the contract. See Note 14 -- “Reinsurance” for additional information. 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 acquisition costs and other underwriting expenses. Ceding commissions are recognized as income on a pro-rata basis over the terms of the policies reinsured, the amount of which is included in policy acquisition and other underwriting expenses in the consolidated statement of income. The unearned portion of ceding commissions that represents recovery of capitalized acquisition costs is classified as a reduction of DAC whereas the remaining unearned balance is classified as deferred revenue in other liabilities. Reinsurance Assumed. From time to time, the Company agrees to assume risk from another insurance company. Reinsurance premiums, commission, cost allowance, and reserves related to reinsured business are accounted for on a basis consistent with those used in accounting for the original policies issued and the terms of the reinsurance contracts. Premiums assumed from other insurance companies are included in gross premiums earned. Ceding commissions on assumed gross written premiums and related costs paid are reflected as DAC which is amortized as expense on a pro-rata basis over the life of the reinsurance agreement. This amortized expense is included in policy acquisition and other underwriting expenses in the consolidated statements of income. Reinsurance Recovered in Advance on Unpaid Losses. Reinsurance recovered in advance on unpaid losses represents cash received in advance from a reinsurer under a reinsurance contract to reimburse the Company’s losses and loss adjustment expenses. The Company is contractually permitted to apply these funds to offset the paid portion of reinsurance recoverable only.
Premium Revenue	Premium Revenue. Premium revenue includes premium from the direct issuance of policies to insureds or the renewal or replacement of insureds’ policies and assumed premium for providing coverage under reinsurance agreements. Premium revenue is earned on a daily pro-rata basis over the term of the policies and is included in gross premiums earned. Unearned premiums represent the portion of the premiums attributable to the unexpired policy term. The Company reviews its policy detail and establishes an allowance for any amount outstanding for more than 90 days.
Policy Fees	Policy Fees. Policy fees represent nonrefundable fees for insurance coverage, which are intended to reimburse a portion of the costs incurred to underwrite the policy. Policy fees are recognized ratably over the policy coverage period.
Revenue from Claims Processing Services	Revenue from Claims Processing Services. The Company provides a claims processing service to a third-party insurance company as a third-party administrator (“TPA”). The service includes investigation, evaluation, adjustment and settlement of a claim. These highly interrelated activities are combined to fulfill the Company’s obligation to provide the claims processing service under a contract. As such, they are considered a single performance obligation for revenue recognition purposes. Fees are established on a per-claim basis by type of claim. For each type of claim, the per-claim fee revenue is recognized over an average claim processing period. The Company may incur additional costs for outsourced services in connection with the investigation, coverage analysis, adjustment, negotiation, settlement, defense or general processing of a claim. These costs are reimbursable from the customer. The Company has control over how an outsourced service is performed on its behalf. Thus, these pass-through costs are recognized as revenue in the gross amount to which the Company expects to be entitled and when the outsourced service is completed and paid or accrued by the Company. For a certain type of claim and in addition to the per-claim service fee, the Company is entitled to additional revenue which is determined based on a fixed percent of the paid indemnification of the loss per claim. The revenue is recognized when the indemnification is paid by the Company. Revenue related to claims processing services is included in other revenue in the consolidated statements of income. For the years ended December 31, 2023, 2022 and 2021, revenues from claims processing services were $766, $3,425 and $4,554, respectively. At December 31, 2023 and 2022, other assets included $0 and $2,543, respectively, of amounts receivable attributable to this service.
Insurance Guaranty Association Assessments	Insurance Guaranty Association Assessments. The Company’s insurance subsidiaries may be assessed by state associations such as the Florida Insurance Guaranty Association. The assessments are intended to be used for the payment of covered claims of insolvent insurance entities. The assessments are generally based on a percentage of premiums written during or following the year of insolvency. Liabilities are recognized when the assessments are probable to be imposed on the premiums on which they are expected to be based and the amounts can be reasonably estimated. An insurer is generally permitted to recover the entire amount of assessments from in-force and future policyholders through policy surcharges. U.S. GAAP provides that the Company should record an asset based on the amount of written or obligated-to-write premiums and limited to the amounts recoverable over the life of the in-force policies.
Foreign Currency	Foreign Currency. The functional currency of the Company’s Indian subsidiary is the U.S. dollar. As such, the monetary assets and liabilities of this subsidiary are remeasured into U.S. dollars at the exchange rate in effect on the balance sheet date. Non-monetary assets and liabilities are remeasured using historical rates. Expenses recorded in the local currency are remeasured at the prevailing exchange rate. Exchange gains and losses resulting from these remeasurements are included in other operating expenses.
Income Taxes	Income Taxes. The Company files consolidated federal and state income tax returns and allocates taxes among its subsidiaries in accordance with a written tax-allocation agreement. The Company accounts for income taxes in accordance with U.S. GAAP, resulting in two components of income tax expense and benefit: current and deferred. Current income tax expense and benefit 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 and benefit 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. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than fifty percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management’s judgment. Deferred tax assets are reduced by a valuation allowance if, based on the weight of both positive and negative evidence available including recent operating results, available tax planning strategies, and projected future taxable income, it is more likely than not that some portion or all of a deferred tax asset will not be realized.
Fair Value of Financial Instruments	Fair Value of Financial Instruments. The carrying amounts for the Company’s cash and cash equivalents approximate their fair values at December 31, 2023 and 2022. Fair values for securities or financial instruments are based on the framework for measuring fair value established by U.S. GAAP (see Note 7 -- “Fair Value Measurements”).
Stock-Based Compensation	Stock-Based Compensation. The Company accounts for stock-based compensation under the fair value recognition provisions of U.S. GAAP which require the measurement and recognition of compensation for all stock-based awards made to employees, non-employee directors (see Note 23 -- “Stock-Based Compensation”), and third-party award recipients based on estimated fair values. In accordance with U.S. GAAP, the fair value of stock-based awards granted to employees and non-employee directors is generally recognized as compensation expense over the requisite service period, which is defined as the period during which a recipient is required to provide service in exchange for an award. Forfeitures of the Company’s stock-based awards are accounted for as they occur. The Company uses a straight-line attribution method for all grants that include only a service-based vesting condition. Restricted stock grants with market-based vesting conditions are expensed over the derived service period. Expensing market-based awards may be expedited if the conditions are met sooner than anticipated. For awards granted to third-party recipients, the cost of the grant is recognized in the same period(s) and in the same manner as if the Company had paid cash. The Company’s outstanding stock-based awards include stock options, warrants, and restricted stock awards with service and market-based vesting conditions. Compensation expense related to all awards granted to employees and non-employee directors is included in general and administrative personnel expenses. The Company receives a windfall tax benefit for certain stock option exercises and for restricted stock awards if these awards vest at a higher value than the value used to recognize compensation expense. In the event the restricted stock awards vest at a lower value than the value used to recognize compensation expense, the Company experiences a tax shortfall. The Company recognizes tax windfalls and shortfalls in the consolidated statement of income.
Basic and Diluted Earnings Per Common Share	Basic and Diluted Earnings Per Common Share. Basic earnings or loss per common share is computed by dividing net income or loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period. U.S. GAAP requires the inclusion of restricted stock as participating securities since holders of the Company’s restricted stock have the right to share in dividends, if declared, equally with common stockholders. In addition, the intrinsic value of restricted stock declines when the Company experiences operating losses. As a result, holders of the Company’s restricted stock are allocated a proportional share of net income and loss determined by dividing total weighted-average shares of restricted stock by the sum of total weighted-average common shares and shares of restricted stock (the “two-class method”). Diluted earnings per common share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted as well as participating equities. During loss periods, common stock equivalents such as stock options and convertible debt are excluded from the calculation of diluted loss per share, as the inclusion would have an anti-dilutive effect. See Note 20 -- “Earnings Per Share” for potentially dilutive securities at December 31, 2023, 2022 and 2021.
Statutory Accounting Practices	Statutory Accounting Practices. The Company’s U.S. insurance subsidiaries comply with statutory accounting practices prescribed by the National Association of Insurance Commissioners and as adopted or permitted by the FLOIR. There are no state prescribed or permitted practices that have been adopted by the Company’s U.S. subsidiaries. In addition, the Company’s Bermuda insurance subsidiary prepares and files financial statements in accordance with the prescribed regulatory accounting practices of the Bermuda Monetary Authority.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2023

Basis of Presentation. The accompanying financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

Principles of Consolidation

Principles of Consolidation. The accompanying consolidated financial statements include the accounts of HCI Group, Inc. and its majority-owned and controlled subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. In addition, the Company evaluates its relationships or investments for consolidation pursuant to authoritative accounting guidance related to the consolidation of variable interest entities under the Variable Interest Model prescribed by the Financial Accounting Standards Board (“FASB”). A variable interest entity is consolidated when the Company has the power to direct activities that most significantly impact the economic performance of the variable interest entity and has the obligation to absorb losses or the right to receive benefits from the variable interest entity that could potentially be significant to the variable interest entity. When a variable interest entity is not consolidated, the Company uses the equity method to account for the investment. Under this method, the carrying value is generally the Company’s share of the net asset value of the unconsolidated entity, and changes in the Company’s share of the net asset value are recorded in net investment income.

Use of Estimates

Use of Estimates. The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as well as the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ materially from these estimates. Material estimates that are particularly susceptible to significant change in the near term are primarily related to losses and loss adjustment expenses, reinsurance with retrospective provisions, reinsurance recoverable, deferred income taxes, limited partnership investments, intangible assets acquired from United, allowance for credit losses, and stock-based compensation expense.

Cash and Cash Equivalents

Cash and Cash Equivalents. The Company considers all short-term highly liquid investments with original maturities of less than three months to be cash and cash equivalents. At December 31, 2023 and 2022, cash and cash equivalents consisted of cash on deposit with financial institutions and securities brokerage firms, and certificates of deposit.

Restricted Cash

Restricted Cash. Restricted cash represents funds in the Company’s sole ownership held by certain states in which the Company’s insurance subsidiaries conduct business to meet regulatory requirements and not available for immediate business use. Funds withheld in an account for which the Company is a co-owner but not the named beneficiary are not considered restricted cash and are included in funds withheld for assumed business on the consolidated balance sheets.

Available-for-Sale Fixed-Maturity Securities

Available-for-Sale Fixed-Maturity Securities. Fixed-maturity securities that are available for sale include debt securities and redeemable preferred stock. The Company’s available-for-sale securities are carried at fair value. Changes in the fair value of available-for-sale securities representing unrealized gains or losses, other than credit losses, are excluded from net investment income and reported in stockholders’ equity as a component of accumulated other comprehensive income (loss), net of deferred income taxes. Realized investment gains and losses from sales are recorded on the trade date and are determined using the first-in first-out (“FIFO”) method. Investment income is recognized as earned and discounts or premiums arising from the purchase of debt securities are recognized in investment income using the interest method over the estimated remaining term of the security. Gains and losses from call redemptions and repayments are charged to investment income.

The Company reviews fixed-maturity securities for impairment on a monthly basis. 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 impairment losses in income.

Impaired securities where the Company has the ability and intent to hold until recovery and believes it is not probable that the Company will be required to sell these securities prior to their anticipated recovery or maturity, are evaluated for the existence of credit-related losses. 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, the failure of the issuer to make a scheduled payment, 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 are 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. If such credit-related losses exist, an allowance for credit losses is established with a charge in the consolidated statement of income. Subsequent changes in the allowance, whether favorable or unfavorable, are recorded on the consolidated statement of income. See additional information in the Allowance for Credit Losses section within this note. Any remaining impairment loss related to other non-credit factors such as changes in interest rates or market conditions is reflected as a component of accumulated other comprehensive income (loss).

Allowance for Credit Losses

Allowance for Credit Losses. Allowance for credit losses represents an estimation of potential losses that the Company may experience due to credit risk. The allowance for credit losses account is a contra account of a financial asset to reflect the net amount expected to be collected. Any increase or decrease in the allowance for credit losses related to investments is recognized and reflected as credit losses on investments in the Company’s consolidated statement of income. For all other financial assets, credit loss expense is included in other operating expenses. When the risk of credit loss becomes certain, the allowance for credit losses account will be written off against the financial asset. Under the Current Expected Credit Loss (“CECL”) model, the Company measures all expected credit losses related to relevant financial assets based on historical experience, current conditions, and reasonable and supportable forecasts which incorporate forward-looking information. The Company primarily uses a discounted cash flow method and a rating-based method in estimating credit losses at a reporting date for financial assets under the scope of the CECL model. The discounted cash flow method is a valuation method used to estimate the value of a financial asset based on its future cash flows. The Company uses this method to determine the expected credit losses for available-for-sale fixed-maturity securities. In addition, the Company elected not to measure an allowance for credit losses for accrued interest receivable as any uncollectible amount is adjusted to interest income on a monthly basis. At present, the exposure to credit losses for certain financial assets related to non-insurance business is considered immaterial to the Company’s financial position.

For certain financial assets related to insurance business such as reinsurance recoverable and reinsurance receivable for premium refund, the Company uses a rating-based method, which is a modified version of the probability of default method. It requires two key inputs: a) the liquidation rate and b) the amount of loss exposure. The liquidation rate, which is published annually, is the ratio of impaired insurance companies that were eventually liquidated to the group of insurance companies considered by A.M. Best in its study. The amount of loss exposure represents the future billing balance, net of any collateral, spread over the projected periods that are based on the Company’s historical claim payment pattern. The rating-based method measures credit losses by multiplying the future billings grouped by insurance rating over the projected periods by their corresponding liquidation rates by insurance rating.

For paid reinsurance recoverable which is due within 90 days after billing, the Company will rely heavily on each reinsurer’s credit rating, recent financial condition, and historical collection problems, if any, in determining the expected credit loss. For risk attributable to disagreements between an insurer and reinsurer regarding a difference in interpretation of provisions in a reinsurance agreement (“dispute risk”), the Company will continue to use an incurred loss method to estimate losses. At December 31, 2023, there was no dispute risk associated with the reinsurance recoverable balance.

Equity Securities

Equity Securities. Equity securities represent ownership interests held by the Company in entities for investment purposes. Unrealized holding gains and losses related to equity securities are reported in the consolidated statements of income as net unrealized investment gains and losses. Realized investment gains and losses from sales are recorded on the trade date and are determined using the FIFO method (see b) Equity Securities in Note 5 -- “Investments”).

Limited Partnership Investments

Limited Partnership Investments. The Company has interests in limited partnerships that are not registered under the United States Securities Act of 1933, as amended, the securities laws of any state or the securities laws of any other jurisdictions. The partnership interests cannot be resold in the public market and any withdrawal is subject to the terms and conditions of the partnership agreements. The Company has no influence over partnership operating and financial policies. The Company uses the equity method to account for the investments with ownership interest greater than five percent. For the investments with ownership interest at five percent or less, the Company uses the net asset value method to estimate the fair value of these investments. The Company generally recognizes its share of the limited partnerships’ earnings or losses on a three-month lag. Due to the lag, the Company may record an adjustment to the Company’s most recent share of net asset value when the amount can be reasonably estimated and a significant adverse impact on the net asset value is expected as a result of a major economic event.

Net investment income or loss from limited partnerships represents a net aggregate amount of operating results allocated to the Company based on the percentage of ownership interest in each limited partnership.

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 statements 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. The Company had a 90% equity interest in a limited liability company (treated as a joint venture under U.S. GAAP) that owned land for lease or for sale. The joint venture was determined to be a variable interest entity as it lacked sufficient equity to finance its activities without additional subordinated financial support. Despite having a majority equity interest, the Company did not have the power to direct the activities that most significantly impact the economic performance of the joint venture and, accordingly, was not required to consolidate the joint venture as its primary beneficiary. As a result, the Company used the equity method to account for this investment.

Real Estate Investments

Real Estate Investments. Real estate investments include real estate and the related assets purchased for investment purposes (see Note 5 -- “Investments”). Real estate and the related depreciable assets are carried at cost, net of accumulated depreciation, which is included in net investment income and allocated over the estimated useful life of the asset using the straight-line method of depreciation. Land is not depreciated. Real estate is evaluated for impairment when events or circumstances indicate the carrying value of the real estate may not be recoverable.

Deferred Policy Acquisition Costs

Deferred Policy Acquisition Costs. Deferred policy acquisition costs (“DAC”) represent direct costs to acquire insurance contracts and consist of premium taxes, inspection fees and commissions paid to outside agents at the time of collection of the policy premium. DAC may also include expenses associated with the transition of policies from other insurers for replacement policies and the issuance of renewal policies under the Company’s own rates and terms. DAC is amortized over the life of the related policy in relation to the amount of gross premiums earned. Ceding commission and related costs paid associated with assumed business are also deferred and amortized over the life of the reinsurance agreement.

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 gross premium earned 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 gross premium earned estimates discussed above are revised.

Property and Equipment

Property and Equipment. Property and equipment is stated at cost less accumulated depreciation and amortization, which is included in other operating expenses. Depreciation is calculated on a straight-line basis over the estimated useful lives as follows: land improvements, five years; building, 39 years; building improvements, three to ten years; computer hardware and software, three years; and furniture and office equipment, three to seven years. Leasehold improvements are amortized over the shorter of the lease term or the asset’s useful life. Land is not depreciated. Expenditures for improvements are capitalized to the property accounts. Replacements and maintenance and repairs that do not improve or extend the life of the respective assets are expensed as incurred. The Company capitalizes both internal and external costs for internally developed software during the application development stage. During the preliminary project and post-implementation stage, internal-use software development costs are expensed as incurred. Capitalized software costs are depreciated on a straight-line basis over the estimated useful life of seven years.

Impairment of Long-Lived Assets

Impairment of Long-Lived Assets. Long-lived assets, such as property and equipment, are reviewed for impairment annually or whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. The Company assesses the recoverability of long-lived assets by determining whether the assets can be recovered from undiscounted future cash flows. Recoverability of long-lived assets is dependent upon, among other things, the Company’s ability to maintain profitability so as to be able to meet its obligations when they become due. In our opinion, based upon current information and projections, tangible long-lived assets will be recovered over the period of benefit.

Leases

Leases. The Company leases office equipment, storage units, and office space from non-affiliates under terms ranging from one month up to nine years. In assessing whether a contract is or contains a lease, the Company first determines whether there is an identified asset in the contract. The Company then determines whether the contract conveys the right to obtain substantially all of the economic benefits from use of the identified asset or the right to direct the use of the identified asset. The Company elects not to record any lease with a term of 12 months or less on the consolidated balance sheet. For such short-term leases, the Company recognizes the lease payments in expense on a straight-line basis over the lease term.

If the contract is or contains a lease and the Company has the right to control the use of the identified asset, the right-of-use (“ROU”) asset and the lease liability is measured from the lease component of the contract and recognized on the consolidated balance sheet. In measuring the lease liability, the Company uses its incremental borrowing rate for a loan secured by a similar asset that has a term similar to the lease term to discount the lease payments. The contract is further evaluated to determine the classification of the lease as to whether it is finance or operating. If the lease is a finance lease, the ROU asset is depreciated to depreciation expense over the shorter of the useful life of the asset or the lease term. Interest expense is recorded in connection with the lease liability using the effective interest method. If the lease is an operating lease, the ROU asset is amortized to lease expense on a straight-line basis over the lease term. For the presentation of finance leases on the Company’s consolidated balance sheets, ROU assets and corresponding lease liabilities are included with property and equipment, net, and long-term debt, respectively. For the presentation of operating leases on the Company’s consolidated balance sheets, ROU assets are presented as right-of-use assets - operating leases and corresponding lease liabilities are reflected as lease liabilities - operating leases.

Lessor Leases

The Company as a lessor leases its commercial and retail properties, boat slips, and docks to non-affiliates at various terms. If the contract gives the Company’s customer the right to control the use of the identified asset, revenue is recognized on a straight-line basis over the lease term. Initial direct costs incurred by the Company are deferred and amortized on a straight-line basis over the lease term. The Company also records an unbilled receivable, which is the amount by which straight-line revenue exceeds the amount billed in accordance with the lease.

Intangible Assets

Intangible Assets. Intangibles related to real estate investments consist of the value attributable to the acquired in-place leases and the primary, or anchor tenant relationships. The value attributable to the anchor tenant relationship represents the economic benefits of having a nationally recognized retailer as the lead tenant, which draws consumer traffic and other tenants to the retail center. These intangibles are amortized to expense over the related lease term. Amortization of the intangibles related to real estate investments is

reflected in net investment income in the consolidated statements of income. The Company reviews these intangible assets for impairment annually or when events or changes in circumstances indicate the carrying value may not be recoverable. In the event the Company determines the carrying value is not recoverable, an impairment loss is recorded in the Company’s consolidated statements of income.

Acquired intangible assets represent the fair value of consideration the Company paid and is estimated to pay in exchange for the renewal rights and non-compete intangible assets acquired from the seller. In the renewal rights transactions, the Company purchased the right, but not the obligation, to offer homeowners insurance coverage to all policyholders of the seller in certain states on the agreed-upon policy replacement date. The renewal rights agreements also contain a non-compete clause whereby the seller agrees not to offer homeowners insurance policies in these states through a specified date. The Company records these intangible assets based on the fair value of the consideration it paid and is estimated to pay to the seller as provided in the renewal rights agreements with the seller. The Company engaged a third-party valuation specialist to assist with the allocation of the renewal rights and non-compete intangible assets acquired. Intangible assets are amortized over their estimated useful lives. Amortization of the renewal rights and non-compete intangible assets is reflected in other operating expenses in the consolidated statements of income. Intangible assets are evaluated to ensure that there is no impairment to carrying value and no change required in the amortization period. See Note 10 -- “Intangible Assets, Net” for additional information.

Funds Withheld for Assumed Business

Funds Withheld for Assumed Business. Pursuant to the Company’s quota share reinsurance agreements with United, trust accounts were established for the benefit of United as beneficiary. The trust balances represent the net amount owed to the Company under the reinsurance agreements. The trusts consist of a) funds deposited to establish the accounts and b) premiums, including any subsequent premium adjustment, and are reduced by commissions and paid losses and loss adjustment expenses. The assets within the trust accounts consist primarily of cash. Funds remaining at the completion of the quota share agreements are to be distributed according to the trust agreements. Prior to United being placed into receivership by the State of Florida on February 27, 2023, United had the exclusive and unconditional right to withdraw funds from the trust accounts on demand with written notice in compliance with the quota share reinsurance agreements. The funds are now under the control of the receiver.

Lease Acquisition Costs

Lease Acquisition Costs. Lease acquisition costs represent capitalized costs of finding and acquiring tenants such as leasing commissions, legal, and marketing expenses. The costs are included in other assets on the consolidated balance sheets. The Company amortizes these costs in other operating expenses on a straight-line basis over the term of a lease.

Long-Term Debt

Long-Term Debt. Long-term debt includes debt instruments and finance lease obligations. A debt instrument is generally classified as a liability and carried at amortized cost, net of any issuance costs. Debt issuance costs are capitalized and amortized to interest expense over the expected life of the debt instrument using the effective interest method. At issuance, a debt instrument with embedded features such as conversion and redemption options is evaluated to determine whether bifurcation and derivative accounting is applicable. 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 and would not impact the initial measurement and expected life of the debt instrument.

Redeemable Noncontrolling Interest

Redeemable Noncontrolling Interest. Redeemable noncontrolling interest represents an economic interest in TTIG and is presented in the temporary equity (mezzanine) section of the consolidated balance sheets. The interest contains rights in dividends, voting, conversion, participation, liquidation preference and redemption. The redemption feature is not solely within the control of TTIG.

The redeemable noncontrolling interest is initially recorded at fair value and is decreased by related issuance costs. The fair value is estimated using a residual fair value approach. The effect of increasing dividend rates is accreted to the redeemable noncontrolling interest with a corresponding reduction in retained income. The effective interest method is used for accretion over the period of the increasing dividend rates. The carrying value of the interest is also subsequently adjusted for accrued dividends and dividend payments. The Company has an option to pay the dividends in cash or make a payment-in-kind. The dividends are accrued monthly assuming that they will be settled in cash.

When the redeemable noncontrolling interest is probable of becoming redeemable, the Company elects to recognize changes in the redemption value immediately as it occurs and adjust the carrying value of the interest to the maximum redemption value which is the higher of the redemption price or fair market value at the reporting date. Such changes in the redemption value are treated as dividends when calculating income available to common stockholders.

Noncontrolling Interests

Noncontrolling Interests. The Company has noncontrolling interests attributable to TTIG. A noncontrolling interest arises when the Company has less than 100% of the voting rights and economic interests in a subsidiary. The noncontrolling interest is periodically adjusted for the expensing of TTIG’s stock-based awards granted to its employees, the interest’s share of TTIG’s net income or loss to common stockholders and change in other comprehensive income or loss.

Prepaid Share Repurchase Forward Contract

Prepaid Share Repurchase Forward Contract. A prepaid share repurchase forward contract is generally a contract that allows the Company to buy from a counterparty a specified number of common shares at a specific time at a given forward price. The Company entered into such a contract and evaluated the characteristics of the forward contract to determine whether it met the definition of a derivative financial instrument pursuant to U.S. GAAP. The Company determined the forward contract was an equity contract on the Company’s common shares requiring physical settlement in common shares of the Company. As such, the transaction was recognized as a component of stockholders’ equity with a charge to additional paid-in capital equal to the prepayment amount, which represents the cash paid to the counterparty. There was no recognition in earnings for changes in fair value in subsequent periods.

Losses and Loss Adjustment Expenses

Losses and Loss Adjustment Expenses. Reserves for losses and loss adjustment expenses (“LAE”) are determined by establishing liabilities in amounts estimated to cover incurred losses and LAE. Such reserves are determined based on the assessment of claims reported and the development of pending claims. These reserves are based on individual case estimates for the reported losses and LAE and estimates of such amounts that are incurred but not reported. Changes in the estimated liability are charged or credited to income as the losses and LAE are settled.

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 statements of income.

Advance Premiums

Advance Premiums. Premium payments received prior to the policy effective date are recorded as advance premiums. Once the policy is in force, the premiums are recorded as described under “Premium Revenue” below.

Premiums Receivable

Premiums Receivable. Premiums receivable represent the amount of premiums due from policyholders for insurance coverage. Premiums are recorded as receivable in the Company’s general ledger on the effective date of the policy. Premiums are billed to the policyholder 45-60 days in advance of the effective date. The policyholder is given a 30-day grace period after the effective date to pay the premium before the insurance coverage is cancelled. If the policyholder does not pay the premium, the Company can cancel the policy and has no obligation to provide insurance coverage. Unpaid renewal policies are cancelled at midnight on the last day of the period for which the policyholder has paid. The unearned premium liability for the cancelled policy is reversed along with the premium receivable balance. Therefore, there is no unpaid earned premium and credit loss associated with the cancelled policy.

However, when the 30-day grace period falls between two reporting periods, the premium receivable balance at the end of the first reporting period may potentially be overstated for not considering the policy that is subsequently cancelled during the following reporting period. To mitigate the overstatement issue, the Company estimates the monetary impact from the subsequent policy cancellation by multiplying the historical cancellation rate to the premiums receivable balance at the reporting date. An allowance for uncollectible premiums, which offsets the balance of premiums receivable, is established by reducing the unearned premiums liability and earned revenues.

At December 31, 2023 and 2022, allowances for uncollectible premiums were $3,152 and $5,362, respectively. The decrease in allowances for uncollectible premiums during 2023 resulted in a $2,113 increase in unearned premiums during the year ended December 31, 2023. The increase in allowances for uncollectible premiums during 2022 resulted in a $3,432 decrease in unearned premiums during the year ended December 31, 2022. For the year ended December 31, 2023, an increase in earned revenues was $97 as opposed to decreases in earned revenues of $180 and $15 for the years ended December 31, 2022 and 2021, respectively.

Reinsurance

Reinsurance Ceded. In the normal course of business, the Company seeks to reduce the loss that may arise from catastrophes or other events by reinsuring certain levels of risk in various areas of exposure with other insurance enterprises or reinsurers. The Company contracts with a number of reinsurers to secure its annual reinsurance coverage, which generally becomes effective June 1st of each year. The Company purchases reinsurance each year taking into consideration probable maximum losses and reinsurance market conditions. Amounts recoverable from reinsurers are estimated in a manner consistent with the applicable reinsurance contract or contracts. Premiums ceded to other companies have been reported as a reduction of gross premiums earned to arrive at net premiums earned. Prepaid reinsurance premiums represent the unexpired portion of premiums ceded to reinsurers.

From time to time, the Company may elect to pay a reinstatement premium to a reinsurer in order to restore an amount of reinsurance coverage limit exhausted by a loss event. When that occurs, the unamortized portion of the existing prepaid reinsurance premium associated with the first coverage limit will be immediately expensed. The reinstatement premium will be recognized as prepaid reinsurance premium which will be amortized to premiums ceded over the remaining coverage period of a contract.

One of the Company’s current reinsurance contracts contains retrospective provisions including terms and conditions that adjust premiums based on the loss experience under the contract. In such cases, a with-and-without method is used to estimate the asset or liability amount to be recognized at each reporting date. The amount of the estimate is the difference between the net contract costs before and after the loss experience under the contract. Estimates related to premium adjustments are recognized in ceded premiums earned. These estimates are reviewed monthly based on the loss experience to date and as adjustments become necessary. Such adjustments in premiums ceded are reflected in the Company’s current operations and recorded in other assets until received upon the expiration of the contract. See Note 14 -- “Reinsurance” for additional information.

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 acquisition costs and other underwriting expenses. Ceding commissions are recognized as income on a pro-rata basis over the terms of the policies reinsured, the amount of which is included in policy acquisition and other underwriting expenses in the consolidated statement of income. The unearned portion of ceding commissions that represents recovery of capitalized acquisition costs is classified as a reduction of DAC whereas the remaining unearned balance is classified as deferred revenue in other liabilities.

Reinsurance Assumed. From time to time, the Company agrees to assume risk from another insurance company. Reinsurance premiums, commission, cost allowance, and reserves related to reinsured business are accounted for on a basis consistent with those used in accounting for the original policies issued and the terms of the reinsurance contracts. Premiums assumed from other insurance companies are included in gross premiums earned. Ceding commissions on assumed gross written premiums and related costs paid are

reflected as DAC which is amortized as expense on a pro-rata basis over the life of the reinsurance agreement. This amortized expense is included in policy acquisition and other underwriting expenses in the consolidated statements of income.

Reinsurance Recovered in Advance on Unpaid Losses. Reinsurance recovered in advance on unpaid losses represents cash received in advance from a reinsurer under a reinsurance contract to reimburse the Company’s losses and loss adjustment expenses. The Company is contractually permitted to apply these funds to offset the paid portion of reinsurance recoverable only.

Premium Revenue

Premium Revenue. Premium revenue includes premium from the direct issuance of policies to insureds or the renewal or replacement of insureds’ policies and assumed premium for providing coverage under reinsurance agreements. Premium revenue is earned on a daily pro-rata basis over the term of the policies and is included in gross premiums earned. Unearned premiums represent the portion of the premiums attributable to the unexpired policy term. The Company reviews its policy detail and establishes an allowance for any amount outstanding for more than 90 days.

Policy Fees

Policy Fees. Policy fees represent nonrefundable fees for insurance coverage, which are intended to reimburse a portion of the costs incurred to underwrite the policy. Policy fees are recognized ratably over the policy coverage period.

Revenue from Claims Processing Services

Revenue from Claims Processing Services. The Company provides a claims processing service to a third-party insurance company as a third-party administrator (“TPA”). The service includes investigation, evaluation, adjustment and settlement of a claim. These highly interrelated activities are combined to fulfill the Company’s obligation to provide the claims processing service under a contract. As such, they are considered a single performance obligation for revenue recognition purposes. Fees are established on a per-claim basis by type of claim. For each type of claim, the per-claim fee revenue is recognized over an average claim processing period.

The Company may incur additional costs for outsourced services in connection with the investigation, coverage analysis, adjustment, negotiation, settlement, defense or general processing of a claim. These costs are reimbursable from the customer. The Company has control over how an outsourced service is performed on its behalf. Thus, these pass-through costs are recognized as revenue in the gross amount to which the Company expects to be entitled and when the outsourced service is completed and paid or accrued by the Company.

For a certain type of claim and in addition to the per-claim service fee, the Company is entitled to additional revenue which is determined based on a fixed percent of the paid indemnification of the loss per claim. The revenue is recognized when the indemnification is paid by the Company.

Revenue related to claims processing services is included in other revenue in the consolidated statements of income. For the years ended December 31, 2023, 2022 and 2021, revenues from claims processing services were $766, $3,425 and $4,554, respectively. At December 31, 2023 and 2022, other assets included $0 and $2,543, respectively, of amounts receivable attributable to this service.

Insurance Guaranty Association Assessments

Insurance Guaranty Association Assessments. The Company’s insurance subsidiaries may be assessed by state associations such as the Florida Insurance Guaranty Association. The assessments are intended to be used for the payment of covered claims of insolvent insurance entities. The assessments are generally based on a percentage of premiums written during or following the year of insolvency. Liabilities are recognized when the assessments are probable to be imposed on the premiums on which they are expected to be based and the amounts can be reasonably estimated. An insurer is generally permitted to recover the entire amount of assessments from in-force and future policyholders through policy surcharges. U.S. GAAP provides that the Company should record an asset based on the amount of written or obligated-to-write premiums and limited to the amounts recoverable over the life of the in-force policies.

Foreign Currency

Foreign Currency. The functional currency of the Company’s Indian subsidiary is the U.S. dollar. As such, the monetary assets and liabilities of this subsidiary are remeasured into U.S. dollars at the exchange rate in effect on the balance sheet date. Non-monetary assets and liabilities are remeasured using historical rates. Expenses recorded in the local currency are remeasured at the prevailing exchange rate. Exchange gains and losses resulting from these remeasurements are included in other operating expenses.

Income Taxes

Income Taxes. The Company files consolidated federal and state income tax returns and allocates taxes among its subsidiaries in accordance with a written tax-allocation agreement.

The Company accounts for income taxes in accordance with U.S. GAAP, resulting in two components of income tax expense and benefit: current and deferred. Current income tax expense and benefit 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 and benefit 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. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than fifty percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management’s judgment. Deferred tax assets are reduced by a valuation allowance if, based on the weight of both positive and negative evidence available including recent operating results, available tax planning strategies, and projected future taxable income, it is more likely than not that some portion or all of a deferred tax asset will not be realized.

Fair Value of Financial Instruments

Fair Value of Financial Instruments. The carrying amounts for the Company’s cash and cash equivalents approximate their fair values at December 31, 2023 and 2022. Fair values for securities or financial instruments are based on the framework for measuring fair value established by U.S. GAAP (see Note 7 -- “Fair Value Measurements”).

Stock-Based Compensation

Stock-Based Compensation. The Company accounts for stock-based compensation under the fair value recognition provisions of U.S. GAAP which require the measurement and recognition of compensation for all stock-based awards made to employees, non-employee directors (see Note 23 -- “Stock-Based Compensation”), and third-party award recipients based on estimated fair values. In accordance with U.S. GAAP, the fair value of stock-based awards granted to employees and non-employee directors is generally recognized as compensation expense over the requisite service period, which is defined as the period during which a recipient is required to provide service in exchange for an award. Forfeitures of the Company’s stock-based awards are accounted for as they occur. The Company uses a straight-line attribution method for all grants that include only a service-based vesting condition. Restricted stock grants with market-based vesting conditions are expensed over the derived service period. Expensing market-based awards may be expedited if the conditions are met sooner than anticipated. For awards granted to third-party recipients, the cost of the grant is recognized in the same period(s) and in the same manner as if the Company had paid cash. The Company’s outstanding stock-based awards include stock options, warrants, and restricted stock awards with service and market-based vesting conditions. Compensation expense related to all awards granted to employees and non-employee directors is included in general and administrative personnel expenses. The Company receives a windfall tax benefit for certain stock option exercises and for restricted stock awards if these awards vest at a higher value than the value used to recognize compensation expense. In the event the restricted stock awards vest at a lower value than the value used to recognize compensation expense, the Company experiences a tax shortfall. The Company recognizes tax windfalls and shortfalls in the consolidated statement of income.

Basic and Diluted Earnings Per Common Share

Basic and Diluted Earnings Per Common Share. Basic earnings or loss per common share is computed by dividing net income or loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period. U.S. GAAP requires the inclusion of restricted stock as participating securities since holders of the Company’s restricted stock have the right to share in dividends, if declared, equally with common stockholders. In addition, the intrinsic value of restricted stock declines when the Company experiences operating losses. As a result, holders of the Company’s restricted stock are allocated a proportional share of net income and loss determined by dividing total weighted-average shares of restricted stock by the sum of total weighted-average common shares and shares of restricted stock (the “two-class method”). Diluted earnings per common share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted as well as participating equities. During loss periods, common stock equivalents such as stock options and convertible debt are excluded from the calculation of diluted loss per share, as the inclusion would have an anti-dilutive effect. See Note 20 -- “Earnings Per Share” for potentially dilutive securities at December 31, 2023, 2022 and 2021.

Statutory Accounting Practices

Statutory Accounting Practices. The Company’s U.S. insurance subsidiaries comply with statutory accounting practices prescribed by the National Association of Insurance Commissioners and as adopted or permitted by the FLOIR. There are no state prescribed or permitted practices that have been adopted by the Company’s U.S. subsidiaries. In addition, the Company’s Bermuda insurance subsidiary prepares and files financial statements in accordance with the prescribed regulatory accounting practices of the Bermuda Monetary Authority.
