Nature of Operations

Nature of Operations	9 Months Ended
	Sep. 30, 2020
Organization Consolidation And Presentation Of Financial Statements [Abstract]
Nature of Operations	Note 1 – Nature of Operations HCI Group, Inc., together with its subsidiaries (“HCI” or the “Company”), is primarily engaged in the property and casualty insurance business through two Florida domiciled insurance companies, Homeowners Choice Property & Casualty Insurance Company, Inc. (“HCPCI”) and TypTap Insurance Company (“TypTap”). HCPCI is authorized to underwrite various homeowners’ property and casualty insurance products and allied lines business in the state of Florida. HCPCI also offers flood-endorsed and wind-only policies to Florida customers and has regulatory approval to underwrite residential property and casualty insurance in the states of Arkansas, California, Maryland, North Carolina, New Jersey, Ohio, Pennsylvania, South Carolina and Texas. However, Florida is still HCPCI’s primary market. TypTap offers standalone flood and homeowners multi-peril policies. In October 2020, TypTap began applying to offer homeowners coverage in 20 states outside of Florida. The operations of both insurance subsidiaries are supported by HCI Group, Inc. and certain HCI subsidiaries. In particular, the Company is developing technologies to collect and analyze claims and other supplemental data to generate savings and efficiency for the operations of the insurance subsidiaries. In addition, Greenleaf Capital, LLC, the Company’s real estate subsidiary, is primarily engaged in the businesses of owning and leasing real estate and operating marina facilities and one restaurant. On February 5, 2020, HCPCI entered into a policy replacement agreement with Anchor Property & Casualty Insurance Company (“Anchor”). Under the agreement, Anchor cancelled all its policies as of April 1, 2020 and HCPCI offered short-term replacement policies to those policyholders, who were under no obligation to accept them. The replacement policies had substantially the same terms and rates as the cancelled polices and would expire on the same dates the cancelled policies would have expired had they not been cancelled. Upon expiration of the replacement policies, HCPCI will offer, but is not obligated to offer, renewals to those policyholders at its own rates and terms. Total replacement policies issued by the Company on April 1, 2020 approximated 40,000. Risks and Uncertainties Caused by Novel Coronavirus (“COVID-19”) On March 11, 2020, the World Health Organization (“WHO”) declared the outbreak of COVID-19 a pandemic. COVID-19 is a respiratory illness caused by a virus that can spread from person to person. To contain the spread of COVID-19, measures have been undertaken in the United States of America and elsewhere around the world. These measures include, but are not limited to, domestic and international travel restrictions, temporary closure of nonessential businesses, cessation of public activity, and work-from-home orders, which has led to significantly reduced economic activity. To prevent the U.S. economy from further deterioration, several state and local governments have relaxed or lifted some of these measures even though infection rates remain above five percent, the level at which the WHO recommends rates fall below for at least 14 days before reopening. In Florida where the Company’s headquarters is located, a statewide stay-at-home order was issued and later lifted in May 2020. In response to the pandemic, the Company temporarily closed its offices in Florida and asked employees to work from home. The Company also closed temporarily its restaurant, but later decided to exit the business permanently in October 2020. Since then, some employees who have gone through the Company’s health safety training are allowed to alternate their work location between home and office. The Company quickly adjusted its technologies and infrastructure to support a remote workforce and maintain business continuity. As a provider of homeowners insurance, the Company continually prepares for disasters and catastrophic events, including events that could disrupt business continuity. On March 27, 2020, Congress passed the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), which is intended to provide fast and direct economic assistance for American workers and families, small businesses, and to preserve jobs in American industries. The CARES Act includes, among other things, provisions relating to payroll tax credits and deferrals, net operating loss carryback periods, alternative minimum tax credits and technical corrections to tax depreciation methods for qualified improvement property. The Company qualifies as a small business under the CARES Act but d id not apply for any of the government loan programs . At present, the Company’s insurance subsidiaries do not foresee a direct material impact from the outbreak of COVID-19 in terms of increased claims and losses. However, the resulting economic uncertainty is adversely affecting the results of the Company’s investment portfolios (See Note 5 – Investments). The Company generally holds or invests premiums collected from policyholders in the financial markets in order to earn income before claims need to be paid. Since the economic outlook started to deteriorate, the Company’s investments in limited partnerships, equity and fixed-maturity securities have decreased in value. In addition, the Company’s insurance subsidiaries may experience difficulties collecting premiums from some policyholders. Policyholders with financial difficulties may decide not to renew insurance policies with the Company. Reinsurance companies with which the Company has contracted may also face liquidity issues and may not timely settle reinsurance balances that become due. Reinsurance costs have increased as reinsurers pay COVID-19 related claims worldwide and face the possibility of increases in the cost of capital needed to fund their operations. Furthermore, due to the impact of the COVID-19 outbreak on retail business activities, rent payments due from the Company’s lessees may be delayed or not received. Some lessees, with the exception of all anchor tenants, have sought rent concessions in order to stay in business. In the near term, the Company determined there is no impairment to its real estate investments or intangible assets as the real estate market is inherently slower moving than equity and debt security markets. For other auxiliary operations such as restaurant and marina business, the temporary closure of these operations has no material impact on the Company’s results of operations. It is too early to gauge the effectiveness of the CARES Act and any upcoming stimulus package in assisting targeted individuals and businesses and preventing further economic downturn. As of the date of issuance of these interim unaudited consolidated financial statements, the extent to which the COVID-19 pandemic may materially affect the Company’s financial condition, liquidity, or results of operations in the medium and long-term future remains uncertain and unquantifiable.

The accompanying unaudited consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 201 9 included in the Company’s Form 10-K, which was filed with the SEC on March 6 , 20 20 . In preparing the interim unaudited consolidated financial statements, management was required to make certain judgments, assumptions, and estimates that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures at the financial reporting date and throughout the periods being reported upon. Certain of the estimates result from judgments that can be subjective and complex and consequently actual results may differ from these estimates. Material estimates that are particularly susceptible to significant change in the near term are related to the Company’s losses and loss adjustment expenses, which include amounts estimated for claims incurred but not yet reported. The Company uses various assumptions and actuarial data it believes to be reasonable under the circumstances to make these estimates. In addition, accounting policies specific to reinsurance with retrospective provisions, reinsurance recoverable, deferred income taxes, and stock-based compensation expense involve significant judgments and estimates material to the Company’s consolidated financial statements. All significant intercompany balances and transactions have been eliminated. Adoption of New Accounting Standards In June 2016, the Financial Accounting Standards Board issued Accounting Standards Update No. 2016-13 (“ASU 2016-13”), Financial Instruments – Credit Losses (Topic 326), effective January 1, 2020. This update amends guidance on the recognition and measurement of credit losses for assets held at amortized cost and available-for-sale debt securities. For assets held at amortized cost, ASU 2016-13 eliminates the probable initial recognition threshold and, instead, requires credit losses to be measured using the Current Expected Credit Loss (“CECL”) model. The CECL model requires the measurement of all expected credit losses based on historical experience, current conditions, and reasonable and supportable forecasts which incorporate forward-looking information. For available-for-sale debt securities, credit losses will continue to be measured in a manner similar to the current standard. Effective January 1, 2020, the Company used a modified retrospective method for transition to the CECL model. The Company recognized a cumulative-effect adjustment of $453 related to reinsurance recoverable to beginning retained income with a corresponding entry to an allowance for credit losses account. Any subsequent changes to the expected credit losses will be recognized in the Company’s consolidated statement of income. 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 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 elects 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. 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. 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. 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 agreement. 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 partnership’s 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 statement of income. As a result, the carrying value of limited partnership investments at each reporting date approximates their estimated fair value. Premium Receivable Premium receivable represents 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 premium receivable balance at the reporting date. The premium receivable balance, together with the unearned premium liability is then reduced by the computed amount. At September 30, 2020 and December 31, 2019, allowances for uncollectible premiums were $2,369 and $528, respectively. Deferred Policy Acquisition Costs Deferred policy acquisition costs (“DAC”) represent direct costs to acquire insurance contracts and consist of premium taxes and commissions paid to outside agents at the time of collection of the policy premium. DAC also includes a cash bonus and other related expenses in association with the successful transition of policies from Anchor for the replacement policies and 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. The method followed in computing DAC limits the amount of such deferred costs to their estimated realizable value, which gives effect to the gross premium earned, related investment income, unpaid losses and loss adjustment expenses and certain other costs expected to be incurred as the premium is earned. DAC is reviewed to determine if it is recoverable from future premium income, including investment income. If such costs are determined to be unrecoverable, they are expensed at the time of determination. The amount of DAC considered recoverable could be reduced in the near term if the estimates of total revenues discussed above are reduced or permanently impaired as a result of the disposition of a line of business. The amount of amortization of DAC could be revised in the near term if any of the estimates discussed above are revised.

This guidance will not have a material impact on the Company’s consolidated financial statements. Accounting Standards Update No. 2020-0 6 . In August 2020, the FASB issued A ccounting S tandards U pdate No. 2020-06 (“ASU 2020-06”) Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic 815-40). ASU 2020-06 remove s certain bifurcation models for convertible debt instruments and convertible preferred stock. Therefore, the embedded conversion features no longer are separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815, Derivatives and Hedging, or that do not result in substantial premiums accounted for as paid-in-capital. The amendments also remove three settlement conditions that are required for equity contracts to qualify for the derivative scope exception and amend the derivative scope exception guidance for contracts in an entity’s own equity. In addition , the amendments expand disclosure requirements for convertible instruments and simplif y areas of the guidance for diluted earnings-per-share calculations that are impacted by the amendments. ASU 2020-06 is effective for the Company beginning with the first quarter of 2022 and will be applied prospectively. Early adoption is permitted.

Allowance for Credit Losses of Available-for-Sale Fixed-Maturity Securities The Company regularly reviews its individual investment securities for credit impairment. The Company considers various factors in determining whether each individual security is impaired, including- • the financial condition and near-term prospects of the issuer, including any specific events that may affect its operations or earnings; • the extent to which the market value of the security has been below its cost or amortized cost; • general market conditions and industry or sector specific factors and other qualitative factors; • nonpayment by the issuer of its contractually obligated interest and principal payments; and • the Company’s intent and ability to hold the investment for a period of time sufficient to allow for the recovery of costs.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 7 – Fair Value Measurements The Company records and discloses certain financial assets at their estimated fair value. The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels as follows: Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 - Other inputs that are observable for the asset, either directly or indirectly such as quoted prices for identical assets that are not observable throughout the full term of the asset. Level 3 - Inputs that are unobservable. Valuation Methodology Cash and cash equivalents Cash and cash equivalents primarily consist of money-market funds and certificates of deposit maturing within 90 days. Their carrying value approximates fair value due to the short maturity and high liquidity of these funds. Restricted cash Restricted cash represents cash held by state authorities and the carrying value approximates fair value. Short-term investments Short-term investments consist of certificates of deposit with maturities of 91 to 365 days. Due to their short maturity, the carrying value approximates fair value. Fixed-maturity and equity securities Estimated fair values of the Company’s fixed-maturity and equity securities are determined in accordance with U.S. GAAP, using valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Fair values are generally measured using quoted prices in active markets for identical securities or other inputs that are observable either directly or indirectly, such as quoted prices for similar securities. In those instances where observable inputs are not available, fair values are measured using unobservable inputs. Unobservable inputs reflect the Company’s own assumptions about the assumptions that market participants would use in pricing the security and are developed based on the best information available in the circumstances. Fair value estimates derived from unobservable inputs are significantly affected by the assumptions used, including the discount rates and the estimated amounts and timing of future cash flows. The derived fair value estimates cannot be substantiated by comparison to independent markets and are not necessarily indicative of the amounts that would be realized in a current market exchange. The estimated fair values for securities that do not trade on a daily basis are determined by management, utilizing prices obtained from an independent pricing service and information provided by brokers, which are level 2 inputs. Management reviews the assumptions and methods utilized by the pricing service and then compares the relevant data and pricing to broker-provided data. The Company gains assurance of the overall reasonableness and consistent application of the assumptions and methodologies and compliance with accounting standards for fair value determination through ongoing monitoring of the reported fair values. Revolving Credit Facility The Company’s revolving credit facility is a variable-rate loan. The interest rate is periodically adjusted based on the London Interbank Offered Rate plus a spread. As a result, its carrying value approximates fair value. Long-term debt The following table summarizes components of the Company’s long-term debt and methods used in estimating their fair values: Maturity Date Valuation Methodology 4.25% Convertible senior notes 2037 Quoted price 3.90% Promissory note 2032 Discounted cash flow method/Level 3 inputs 4% Promissory note 2031 Discounted cash flow method/Level 3 inputs 3.75% Callable promissory note 2036 Discounted cash flow method/Level 3 inputs 4.55% Promissory note 2036 Discounted cash flow method/Level 3 inputs Assets Measured at Estimated Fair Value on a Recurring Basis The following table presents information about the Company’s financial assets measured at estimated fair value on a recurring basis.

The Company’s recent cash dividends on common stock have exceeded $0.35 per share, resulting in adjustments to the conversion rate of the 4.25% Convertible Notes. Accordingly, as of September 30, 2020, the conversion rate of the Company’s 4.25% Convertible Notes was 16.42 shares of common stock for each $1 in principal amount, which was the equivalent of approximately $60.91 per share.

Reinsurance

Insurance [Abstract]
Reinsurance	Note 13 – Reinsurance The Company cedes a portion of its homeowners’ insurance exposure to other entities under catastrophe excess of loss reinsurance contracts and one quota share reinsurance agreement. Ceded premiums under most catastrophe excess of loss reinsurance contracts are subject to revision resulting from subsequent adjustments in total insured value. Under the terms of the quota share reinsurance agreement, the Company is entitled to a 30% ceding commission on ceded premiums written. The reinsurance premiums under one flood catastrophe excess of loss reinsurance contract are generally determined on a quarterly basis based on the premiums associated with the applicable flood total insured value in force on the last day of the preceding quarter. The Company remains liable for claims payments in the event that any reinsurer is unable to meet its obligations under the reinsurance agreements. Failure of reinsurers to honor their obligations could result in losses to the Company. The Company evaluates the financial condition of its reinsurers and monitors concentrations of credit risk arising from similar geographic regions, activities or economic characteristics of the reinsurers to minimize its exposure to significant losses from reinsurer insolvencies. The Company contracts with a number of reinsurers to secure its annual reinsurance coverage, which generally becomes effective June 1 st The impact of the reinsurance contracts on premiums written and earned is as follows: Three Months Ended Nine Months Ended September 30, September 30, 2020 2019 2020 2019 Premiums Written: Direct $ 116,464 $ 97,331 $ 364,942 $ 298,384 Assumed (13 ) — (92 ) (2 ) Gross written 116,451 97,331 364,850 298,382 Ceded (44,231 ) (31,568 ) (109,304 ) (94,298 ) Net premiums written $ 72,220 $ 65,763 $ 255,546 $ 204,084 Premiums Earned: Direct $ 106,337 $ 86,002 $ 303,956 $ 251,916 Assumed 357 — 2,906 (2 ) Gross earned 106,694 86,002 306,862 251,914 Ceded (44,231 ) (31,568 ) (109,304 ) (94,298 ) Net premiums earned $ 62,463 $ 54,434 $ 197,558 $ 157,616 During the three and nine months ended September 30, 2020, the Company recognized ceded losses of $1,871 and $2,220, respectively, as a reduction in losses and loss adjustment expenses, and ceded losses of $113,888 were recognized in each of the three and nine months ended September 30, 2019. At September 30, 2020 and December 31, 2019, there were 38 and 31 reinsurers, respectively, participating in the Company’s reinsurance program. Total gross amounts recoverable and receivable from reinsurers at September 30, 2020 and December 31, 2019 were $95,274 and $132,678, respectively. Approximately 58.6% of the reinsurance recoverable balance at September 30, 2020 was receivable from three reinsurers, including the Florida Hurricane Catastrophe Fund, a state trust fund. Based on all available information considered in the rating-based method described in Note 2 – “Summary of Significant Accounting Policies,” the Company recognized a decrease in credit loss expense of $14 and $363 for the three and nine months ended September 30, 2020, respectively. Allowances for credit losses related to the reinsurance recoverable balance were $90 and $0 at September 30, 2020 and December 31, 2019, respectively. One of the reinsurance contracts includes retrospective provisions that adjust premiums in the event losses are minimal or zero. For the three and nine months ended September 30, 2020, the Company recognized reductions in premiums ceded of $4,680 and $10,440, respectively, related to these adjustments in the consolidated statement of income. For the three and nine months ended September 30, 2019, the Company recognized net reductions in premiums ceded of $2,520 and $4,258, respectively, related to these adjustments. Amounts receivable pursuant to retrospective provisions are reflected in other assets. At September 30, 2020 and December 31, 2019, other assets included $6,240 and $9,480 related to these adjustments, respectively. In June 2020, the Company received $13,680 of premium refund under the retrospective reinsurance contract that ended May 31, 2020. Management believes the credit risk associated with the collectability of these accrued benefits is minimal as the amount receivable is concentrated with one reinsurer and the Company monitors the creditworthiness of this reinsurer based on available information about the reinsurer’s financial condition.

Insurance [Abstract]
Losses and Loss Adjustment Expenses	Note 14 – Losses and Loss Adjustment Expenses The liability for losses and loss adjustment expenses is determined on an individual case basis for all claims reported. The liability also includes amounts for unallocated expenses, anticipated future claim development and losses incurred but not reported. The Company primarily writes insurance in the state of Florida, which could be exposed to hurricanes or other natural catastrophes. The occurrence of a major catastrophe could have a significant effect on the Company’s quarterly results and cause a temporary disruption of the normal operations of the Company. However, the Company is unable to predict the frequency or severity of any such events that may occur in the near term or thereafter. Activity in the liability for unpaid losses and loss adjustment expenses is summarized as follows: Three Months Ended Nine Months Ended September 30, September 30, 2020 2019 2020 2019 Net balance, beginning of period* $ 123,129 $ 95,345 $ 98,174 $ 94,826 Incurred, net of reinsurance, related to: Current period 50,543 25,177 116,839 70,914 Prior period 1,200 2,150 2,825 7,702 Total incurred, net of reinsurance 51,743 27,327 119,664 78,616 Paid, net of reinsurance, related to: Current period (21,175 ) (15,111 ) (36,988 ) (32,819 ) Prior period (9,386 ) (12,763 ) (36,539 ) (45,825 ) Total paid, net of reinsurance (30,561 ) (27,874 ) (73,527 ) (78,644 ) Net balance, end of period 144,311 94,798 144,311 94,798 Add: reinsurance recoverable before allowance for credit losses 75,034 143,123 75,034 143,123 Gross balance, end of period $ 219,345 $ 237,921 $ 219,345 $ 237,921 *Net balance represents beginning-of-period liability for unpaid losses and loss adjustment expenses less beginning-of-period reinsurance recoverable for unpaid losses and loss adjustment expenses. The establishment of loss reserves is an inherently uncertain process and changes in loss reserve estimates are expected as these estimates are subject to the outcome of future events. Changes in estimates, or differences between estimates and amounts ultimately paid, are reflected in the operating results of the period during which such estimates are adjusted. During the three months ended September 30, 2020, the Company recognized losses related to prior periods of $1,200 primarily to increase the reserve for 2017, 2015 and prior loss years. For the nine months ended September 30, 2020, the Company recognized losses related to prior periods of $2,825 for unfavorable development for 2019 and prior loss years resulting from litigation. Estimated losses of $17,700, net of reinsurance, related to Hurricane Sally are included in the 2020 loss year.

Segment Reporting [Abstract]
Segment Information	Note 15 – Segment Information The Company identifies its operating divisions based on organizational structure and revenue source. Currently, the Company has three reportable segments: insurance operations, real estate operations, and corporate and other. Due to their economic characteristics, the Company’s property and casualty insurance division and reinsurance division are grouped together into one reportable segment under insurance operations. The real estate operations segment includes companies engaged in operating commercial properties the Company owns for investment purposes or for use in its own operations. The corporate and other segment represents the activities of the holding companies, the information technology division, and other companies that do not meet the quantitative and qualitative thresholds for a reportable segment. The determination of segments may change over time due to changes in operational emphasis, revenues, and results of operations. The Company’s chief executive officer, who serves as the Company’s chief operating decision maker, evaluates each division’s financial and operating performance based on revenue and operating income. For the three months ended September 30, 2020 and 2019, revenues from the Company’s insurance operations before intracompany elimination represented 71.1% and 95.2%, respectively, of total revenues of all operating segments. For the nine months ended September 30, 2020 and 2019, revenues from the Company’s insurance operations before intracompany elimination represented 86.2% and 95.0%, respectively, of total revenues of all operating segments. At September 30, 2020 and December 31, 2019, insurance operations’ total assets represented 83.0% and 85.5%, respectively, of the combined assets of all operating segments. The following tables present segment information reconciled to the Company’s consolidated statements of income. Intersegment transactions are not eliminated from segment results.

Income Tax Disclosure [Abstract]
Income Taxes	Note 17 -- Income Taxes During the three months ended September 30, 2020 and 2019, the Company recorded approximately $6,146 and $1,866 respectively, of income taxes, which resulted in effective tax rates of 28.5% and 24.2%, respectively. The increase in the effective tax rate as compared with the corresponding period in the prior year was primarily attributable to the non-deductibility of certain executive compensation. Furthermore, the Florida corporate income tax rate was reduced from 5.5% to 4.458% in September 2019. During the nine months ended September 30, 2020 and 2019, the Company recorded approximately $9,143 and $7,173, respectively, of income taxes, which resulted in effective tax rates of 26.9% and 26.3%, respectively. The slight increase in the effective tax rate in 2020 as compared with the corresponding period in the prior year was primarily attributable to the non-deductibility of executive compensation, offset by the recognition of the tax refund from the State of Florida for 2018 income taxes , and the recognition of windfall tax benefits related to share-based awards. The Company’s estimated annual effective tax rate differs from the statutory federal tax rate due to state and foreign income taxes as well as certain nondeductible and tax-exempt items. In addition, the Company determined there w ere no significant tax implications as a result of the CARES Act.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited, consolidated financial statements for HCI Group, Inc. and its majority-owned and controlled subsidiaries (collectively, the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information, and the Securities and Exchange Commission (“SEC”) rules for interim financial reporting. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been omitted pursuant to such rules and regulations. However, in the opinion of management, the accompanying consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the Company’s financial position as of September 30, 2020 and the results of operations and cash flows for the periods presented. The results of operations for the interim periods presented are not necessarily indicative of the results of operations to be expected for any subsequent interim period or for the fiscal year ending December 31, 2020. The accompanying unaudited consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 201 9 included in the Company’s Form 10-K, which was filed with the SEC on March 6 , 20 20 . In preparing the interim unaudited consolidated financial statements, management was required to make certain judgments, assumptions, and estimates that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures at the financial reporting date and throughout the periods being reported upon. Certain of the estimates result from judgments that can be subjective and complex and consequently actual results may differ from these estimates. Material estimates that are particularly susceptible to significant change in the near term are related to the Company’s losses and loss adjustment expenses, which include amounts estimated for claims incurred but not yet reported. The Company uses various assumptions and actuarial data it believes to be reasonable under the circumstances to make these estimates. In addition, accounting policies specific to reinsurance with retrospective provisions, reinsurance recoverable, deferred income taxes, and stock-based compensation expense involve significant judgments and estimates material to the Company’s consolidated financial statements. All significant intercompany balances and transactions have been eliminated.
Adoption of New Accounting Standards	Adoption of New Accounting Standards In June 2016, the Financial Accounting Standards Board issued Accounting Standards Update No. 2016-13 (“ASU 2016-13”), Financial Instruments – Credit Losses (Topic 326), effective January 1, 2020. This update amends guidance on the recognition and measurement of credit losses for assets held at amortized cost and available-for-sale debt securities. For assets held at amortized cost, ASU 2016-13 eliminates the probable initial recognition threshold and, instead, requires credit losses to be measured using the Current Expected Credit Loss (“CECL”) model. The CECL model requires the measurement of all expected credit losses based on historical experience, current conditions, and reasonable and supportable forecasts which incorporate forward-looking information. For available-for-sale debt securities, credit losses will continue to be measured in a manner similar to the current standard. Effective January 1, 2020, the Company used a modified retrospective method for transition to the CECL model. The Company recognized a cumulative-effect adjustment of $453 related to reinsurance recoverable to beginning retained income with a corresponding entry to an allowance for credit losses account. Any subsequent changes to the expected credit losses will be recognized in the Company’s consolidated statement of income.
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 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 elects 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. 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. 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.
Limited Partnerships 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 agreement. 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 partnership’s 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 statement of income. As a result, the carrying value of limited partnership investments at each reporting date approximates their estimated fair value.
Premium Receivable	Premium Receivable Premium receivable represents 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 premium receivable balance at the reporting date. The premium receivable balance, together with the unearned premium liability is then reduced by the computed amount. At September 30, 2020 and December 31, 2019, allowances for uncollectible premiums were $2,369 and $528, respectively.
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 and commissions paid to outside agents at the time of collection of the policy premium. DAC also includes a cash bonus and other related expenses in association with the successful transition of policies from Anchor for the replacement policies and 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. The method followed in computing DAC limits the amount of such deferred costs to their estimated realizable value, which gives effect to the gross premium earned, related investment income, unpaid losses and loss adjustment expenses and certain other costs expected to be incurred as the premium is earned. DAC is reviewed to determine if it is recoverable from future premium income, including investment income. If such costs are determined to be unrecoverable, they are expensed at the time of determination. The amount of DAC considered recoverable could be reduced in the near term if the estimates of total revenues discussed above are reduced or permanently impaired as a result of the disposition of a line of business. The amount of amortization of DAC could be revised in the near term if any of the estimates discussed above are revised.
