Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1 — Summary of Significant Accounting Policies 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 June 30, 2019 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, 2019. 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, 2018 included in the Company’s Form 10-K, 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 February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2016-02 2016-02”), 2016-02 2016-02 No. 2018-01, No. 2018-10, No. 2018-11, No. 2018-20, 2019-01, right-of-use Effective January 1, 2019, the Company adopted the new standard using the effective date as its date of initial application. As a result, financial information is not updated and the disclosures required under the new standard are not provided for dates and periods prior to January 1, 2019. The Company elected a package of practical expedients, which permits the Company to not reassess under the new standard its prior conclusions about lease identification, lease classification, and initial direct costs. Upon adoption, the Company, as a lessee, recognized ROU assets of approximately $771 and lease liabilities of approximately $812 for all operating leases except for those that have a lease term of 12 months or less. Leases The Company leases office equipment, storage units, and office space from non-affiliates If the contract is or contains a lease and the Company has the right to control the use of the identified asset, the 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 sheet, 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 sheet, ROU assets and corresponding lease liabilities are included with other assets and other liabilities, respectively. The Company as a lessor leases its commercial and retail properties, boat slips, and docks to non-affiliates Reclassification Certain reclassifications of prior year amounts have been made to conform to the current year presentation.

The scheduled contractual maturities of fixed-maturity securities as of June 30, 2019 and December 31, 2018 are as follows: Amortized Estimated As of June 30, 2019 Due in one year or less $ 43,816 $ 44,011 Due after one year through five years 151,617 153,201 Due after five years through ten years 7,576 7,916 Due after ten years 4,554 4,786 $ 207,563 $ 209,914 Amortized Estimated As of December 31, 2018 Due in one year or less $ 50,659 $ 50,574 Due after one year through five years 117,826 116,498 Due after five years through ten years 11,602 11,253 Due after ten years 4,583 4,398 $ 184,670 $ 182,723 Sales of Available-for-Sale Proceeds received, and the gross realized gains and losses from sales of available-for-sale Proceeds Gross Gross Three months ended June 30, 2019 $ 74 $ — $ — Three months ended June 30, 2018 $ 559 $ — $ (35 ) Six months ended June 30, 2019 $ 2,985 $ 34 $ (1 ) Six months ended June 30, 2018 $ 77,769 $ 1,161 $ (500 ) Other-than-temporary Impairment The Company regularly reviews its individual investment securities for other-than-temporary impairment. The Company considers various factors in determining whether each individual security is other-than-temporarily impaired, including- • the financial condition and near-term prospects of the issuer, including any specific events that may affect its operations or earnings; • the length of time and the extent to which the market value of the security has been below its cost or amortized cost; • general market conditions and industry or sector specific factors and other qualitative factors; • nonpayment by the issuer of its contractually obligated interest and principal payments; and • the Company’s intent and ability to hold the investment for a period of time sufficient to allow for the recovery of costs. There was no impairment loss recognized for the three and six months ended June 30, 2019. For the three and six months ended June 30, 2018, the Company recognized $40 and $80, respectively, of impairment loss on one fixed-maturity security. At June 30, 2019, none of the fixed-maturity securities were considered other-than-temporarily impaired versus one fixed-maturity security at June 30, 2018. Securities with gross unrealized loss positions at June 30, 2019 and December 31, 2018, aggregated by investment category and length of time the individual securities have been in a continuous loss position, are as follows: Less Than Twelve Months Twelve Months or Longer Total As of June 30, 2019 Gross Estimated Gross Estimated Gross Estimated U.S. Treasury and U.S. government agencies $ — $ — $ (13 ) $ 2,675 $ (13 ) $ 2,675 Corporate bonds — — (288 ) 31,727 (288 ) 31,727 Exchange-traded debt (5 ) 1,060 — — (5 ) 1,060 Total $ (5 ) $ 1,060 $ (301 ) $ 34,402 $ (306 ) $ 35,462 At June 30, 2019, there were 22 securities in an unrealized loss position.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 6 — 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. Short-term investments Short-term investments consist of certificates of deposit and zero-coupon 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. Limited Partnership Investments As described in Note 4 — “Investments” under Limited Partnership Investments 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 Valuation Methodology 3.875% Convertible senior notes 2019 Quoted price 4.25% Convertible senior notes 2037 Quoted price 3.95% Promissory note 2020 Discounted cash flow method/Level 3 inputs 4% Promissory note 2031 Discounted cash flow method/Level 3 inputs 3.75% Callable promissory note 2036 Discounted cash flow method/Level 3 inputs 4.55% Promissory note 2036 Discounted cash flow method/Level 3 inputs Assets Measured at Estimated Fair Value on a Recurring Basis The following table presents information about the Company’s financial assets measured at estimated fair value on a recurring basis.

Insurance [Abstract]
Reinsurance	Note 10 — Reinsurance The Company cedes a portion of its insurance exposure to other entities under catastrophe excess of loss reinsurance contracts and one quota share reinsurance agreement. 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 1st each year. The Company purchases reinsurance each year taking into consideration probable maximum losses and reinsurance market conditions. The impact of the reinsurance contracts on premiums written and earned is as follows: Three Months Ended Six Months Ended 2019 2018 2019 2018 Premiums Written: Direct $ 133,441 $ 132,391 $ 201,053 $ 202,616 Assumed — (19 ) (2 ) (97 ) Gross written 133,441 132,372 201,051 202,519 Ceded (31,317 ) (32,954 ) (62,730 ) (65,204 ) Net premiums written $ 102,124 $ 99,418 $ 138,321 $ 137,315 Premiums Earned: Direct $ 83,315 $ 85,207 $ 165,914 $ 170,036 Assumed — 712 (2 ) 1,655 Gross earned 83,315 85,919 165,912 171,691 Ceded (31,317 ) (32,954 ) (62,730 ) (65,204 ) Net premiums earned $ 51,998 $ 52,965 $ 103,182 $ 106,487 There were no ceded losses recognized during the three and six months ended June 30, 2019. During the three and six months ended June 30, 2018, ceded losses of $58,671 and $58,466, respectively, were recognized as a reduction in losses and losses adjustment expenses. At June 30, 2019 and December 31, 2018, there were 31 and 38 reinsurers, respectively, participating in the Company’s reinsurance program. Total amounts recoverable and receivable from reinsurers at June 30, 2019 and December 31, 2018 were $78,080 and $123,911, respectively. Approximately 36.0% of the reinsurance recoverable balance at June 30, 2019 was concentrated in five reinsurers. Based on the insurance ratings, the payment history and the financial strength of the reinsurers, management believes there was no significant credit risk associated with its reinsurers’ obligations to perform on any prepaid reinsurance contract and to fund any reinsurance recoverable balance as of June 30, 2019. One of the reinsurance contracts includes retrospective provisions that adjust premiums in the event losses are minimal or zero. For the three and six months ended June 30, 2019, the Company recognized reductions in premiums ceded of $1,226 and $1,738, respectively, related to these adjustments. In contrast, these adjustments were reflected in the consolidated statements of income as net increases in ceded premiums of $378 and $715 for the three and six months ended June 30, 2018, respectively, of which $400 and $448 related to the Company’s contract with Oxbridge Reinsurance Limited, a related party, which was terminated effective June 1, 2018. In addition, adjustments related to retrospective provisions are reflected in other assets. At June 30, 2019 and December 31, 2018, other assets included $4,440 and $3,136, respectively. 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 11 — 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 Six Months Ended 2019 2018 2019 2018 Net balance, beginning of period* $ 98,453 $ 91,403 $ 94,826 $ 97,818 Incurred, net of reinsurance, related to: Current period 21,416 20,917 45,737 40,407 Prior period 2,877 886 5,552 1,051 Total incurred, net of reinsurance 24,293 21,803 51,289 41,458 Paid, net of reinsurance, related to: Current period (13,778 ) (9,710 ) (17,708 ) (14,157 ) Prior period (13,623 ) (14,107 ) (33,062 ) (35,730 ) Total paid, net of reinsurance (27,401 ) (23,817 ) (50,770 ) (49,887 ) Net balance, end of period 95,345 89,389 95,345 89,389 Add: reinsurance recoverable 58,897 82,998 58,897 82,998 Gross balance, end of period $ 154,242 $ 172,387 $ 154,242 $ 172,387 * Net balance represents beginning-of-period beginning-of-period The establishment of loss reserves is an inherently uncertain process and changes in loss reserve estimates are expected as these estimates are subject to the outcome of future events. Changes in estimates, or differences between estimates and amounts ultimately paid, are reflected in the operating results of the period during which such estimates are adjusted. During the three and six months ended June 30, 2019, the Company recognized losses related to prior periods of $2,877 and $5,552, respectively, which were primarily attributable to unfavorable development resulting from litigation. Included in adverse development for the three and six months ended June 30, 2019 were losses related to Hurricane Matthew of $242 and $1,052, respectively. Losses for the 2019 loss year included estimated losses of $5,250 related to one severe storm event during the first quarter.

Segment Reporting [Abstract]
Segment Information	Note 12 — 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 June 30, 2019 and 2018, revenues from the Company’s insurance operations before intracompany elimination represented 95.2% and 95.6%, respectively, of total revenues of all operating segments. For the six months ended June 30, 2019 and 2018, revenues from the Company’s insurance operations before intracompany elimination represented 94.9% and 95.2%, respectively, of total revenues of all operating segments. At June 30, 2019 and December 31, 2018, insurance operations’ total assets represented 84.6% and 85.9%, 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 Taxes	Note 14 — Income Taxes During the three months ended June 30, 2019 and 2018, the Company recorded approximately $2,762 and $5,117 respectively, of income taxes, which resulted in effective tax rates of 26.8% and 44.4%, respectively. The decrease in the effective tax rate was primarily attributable to the derecognition of deferred tax assets of $1,620 for restricted stock awards with market-based vesting conditions that would not vest and the disallowance of the deductibility of the $1,727 expense representing dividends cumulatively paid on such restricted stock awards, both of which occurred in the second quarter of 2018 (see Restricted Stock Awards tax-exempt

For the six months ended June 30, 2019 and 2018, the Company recognized $425 and $246, respectively, of compensation expense. Deferred tax benefits related to stock options were $20 for each of the three months ended June 30, 2019 and 2018, and $39 for each of the six months ended June 30, 2019 and 2018. At June 30, 2019 and December 31, 2018, there was $2,280 and $1,359, respectively, of unrecognized compensation expense related to nonvested stock options. The Company expects to recognize the remaining compensation expense over a weighted-average period of 2.9 years. The following table provides assumptions used in the Black-Scholes option-pricing model to estimate the fair value of the stock options granted during the six months ended June 30, 2019 and 2018: 2019 2018 Expected dividend yield 3.34 % 4.00 % Expected volatility 40.17 % 42.22 % Risk-free interest rate 2.53 % 2.57 % Expected life (in years) 5 5 Restricted Stock Awards From time to time, the Company has granted and may grant restricted stock awards to its executive officers, other employees and nonemployee directors in connection with their service to the Company. The terms of the Company’s outstanding restricted stock grants may include service, performance and market-based conditions. The fair value of the awards with market-based conditions is determined using a Monte Carlo simulation method, which calculates many potential outcomes for an award and then establishes fair value based on the most likely outcome. The determination of fair value with respect to the awards containing only performance or service-based conditions is based on the market value of the Company’s common stock on the grant date. Information with respect to the activity of unvested restricted stock awards during the three and six months ended June 30, 2019 and 2018 is as follows: Number of Weighted Nonvested at January 1, 2019 632,296 $ 33.33 Granted 40,000 $ 47.94 Vested (21,250 ) $ 37.69 Forfeited (4,681 ) $ 42.79 Nonvested at March 31, 2019 646,365 $ 34.03 Granted 133,160 $ 41.30 Vested (84,914 ) $ 41.58 Forfeited (264,211 ) $ 23.81 Nonvested at June 30, 2019 430,400 $ 41.06 Nonvested at January 1, 2018 597,690 $ 32.82 Granted 40,000 $ 34.92 Vested (28,643 ) $ 45.17 Forfeited (17,905 ) $ 38.55 Nonvested at March 31, 2018 591,142 $ 31.53 Granted 143,360 $ 43.83 Vested (59,974 ) $ 40.09 Forfeited (27,115 ) $ 32.76 Nonvested at June 30, 2018 647,413 $ 33.41 The Company recognized compensation expense related to restricted stock, which is included in general and administrative personnel expenses, of $1,269 and $897 for the three months ended June 30, 2019 and 2018, respectively, and $2,523 and $1,659 for the six months ended June 30, 2019 and 2018, respectively. At June 30, 2019 and December 31, 2018, there was approximately $15,712 and $11,199, respectively, of total unrecognized compensation expense related to nonvested restricted stock arrangements. The Company expects to recognize the remaining compensation expense over a weighted-average period of 2.9 years. The following table summarizes information about deferred tax benefits recognized and tax benefits realized related to restricted stock awards and paid dividends, and the fair value of vested restricted stock for the three and six months ended June 30, 2019 and 2018. Three Months Ended Six Months Ended 2019 2018 2019 2018 Deferred tax benefits recognized $ 244 $ 180 $ 490 $ 336 Tax benefits realized for restricted stock and paid dividends $ 924 $ 652 $ 985 $ 848 Fair value of vested restricted stock $ 3,530 $ 2,404 $ 4,331 $ 3,698 In May 2019, 260,000 shares of the Company’s restricted stock awards granted to employee and nonemployee directors were forfeited for not meeting their market-based vesting conditions. For the same reason, the Company expects another 24,000 shares of restricted stock awards with similar vesting conditions to be forfeited in November 2019. Any dividend payment associated with these awards was expensed when declared. As a result, for the three months ended June 30, 2019, the Company recognized dividends of $113 related to these awards in general and administrative personnel expenses for $85 and in other operating expenses for $28. For the six months ended June 30, 2019, the Company recognized dividends of $227 in general and administrative personnel expenses for $170 and in other operating expenses for $57. In May 2018, the Company reclassified from retained income dividends of $1,727 cumulatively paid on unvested restricted stock awards with market-based vesting conditions to general and administrative personnel expenses for $1,346 and to other operating expenses for $381.

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 June 30, 2019 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, 2019. 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, 2018 included in the Company’s Form 10-K, 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 February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2016-02 2016-02”), 2016-02 2016-02 No. 2018-01, No. 2018-10, No. 2018-11, No. 2018-20, 2019-01, right-of-use Effective January 1, 2019, the Company adopted the new standard using the effective date as its date of initial application. As a result, financial information is not updated and the disclosures required under the new standard are not provided for dates and periods prior to January 1, 2019. The Company elected a package of practical expedients, which permits the Company to not reassess under the new standard its prior conclusions about lease identification, lease classification, and initial direct costs. Upon adoption, the Company, as a lessee, recognized ROU assets of approximately $771 and lease liabilities of approximately $812 for all operating leases except for those that have a lease term of 12 months or less.
Leases	Leases The Company leases office equipment, storage units, and office space from non-affiliates If the contract is or contains a lease and the Company has the right to control the use of the identified asset, the 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 sheet, 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 sheet, ROU assets and corresponding lease liabilities are included with other assets and other liabilities, respectively. The Company as a lessor leases its commercial and retail properties, boat slips, and docks to non-affiliates
Reclassifications	Reclassification Certain reclassifications of prior year amounts have been made to conform to the current year presentation.
