Subsequent Events [Abstract]
Subsequent Events	Note 30 -- Subsequent Events On January 2, 2024, a $91,085 receivable from maturities of fixed-maturity securities was collected by the Company. On January 22, 2024, TTIG entered into a Stock Redemption Agreement with Centerbridge which allowed TTIG to redeem all of the TTIG Series A Preferred Stock held by Centerbridge. The redemption occurred prior to an optional February 26, 2025 redemption right held by Centerbridge. The redemption totaled $100,000 plus accrued and unpaid dividends of approximately $2,923. The redemption was funded with cash on hand, as well as $50,000 from HCI’s existing revolving credit facility with Fifth Third Bank. At redemption, the difference between the consideration transferred of $102,923 and the redemption date carrying value of $96,695 is recorded as a deemed dividend and is included in net income attributable to redeemable noncontrolling interest which is subtracted from net income when calculating income available to common stockholders. On January 22, 2024, in connection with TTIG's redemption of all of the TTIG Series A Preferred Stock held by Centerbridge, the Company extended the expiration date of the warrant currently held by Centerbridge to purchase 750,000 shares of HCI common stock. The amended and restated warrant extends the expiration as to 450,000 underlying warrant shares in 150,000-share increments to December 31, 2026, December 31, 2027, and December 31, 2028. The remaining 300,000 warrants will continue to have the same original expiration date of February 26, 2025. Such warrant modifications resulted in a $3,386 increase in the fair value of the warrants, which is recorded as a deemed dividend by decreasing retained income and increasing additional paid-in capital. The amount of deemed dividend is included in net income attributable to redeemable noncontrolling interest which is subtracted from net income when calculating net income available to common stockholders. On January 22, 2024, a new shelf registration statement on Form S-3 (the “Shelf Registration”) was filed, replacing the Company’s old universal shelf registration statement filed in September 2023. The new Shelf Registration permits the Company to offer and sell its common stock, preferred stock, debt securities, warrants, and stock purchase contracts and units, from time to time, subject to market conditions and its capital needs. The Shelf Registration will also enable Centerbridge to sell all or a portion of the above-described amended and restated warrant or the shares issuable pursuant to the warrant. As a part of the Shelf Registration, the Company also announced the implementation of an “at-the-market” facility (the “ATM facility”) under which the Company would have the ability to raise up to $75,000 through the issuance of new shares of common stock into the market if it were to so choose. On January 23, 2024, the Company, through TypTap, assumed an additional 9,478 insurance policies from Citizens, representing approximately $48,012 in annualized premiums written. On January 24, 2024, the Company’s Board of Directors declared a quarterly dividend of $0.40 per common share. The dividends are payable on March 15, 2024 to stockholders of record on February 16, 2024. On February 14, 2024, upon approval from the receiver of United, TypTap received $15,000 from the trust account that holds funds withheld for the assumed business on the Southeast Region quota share reinsurance agreement. In addition, $4,462 was withdrawn in February 2024 by the receiver from the trust accounts to settle for paid losses and LAE related to the Northeast Region and the Southeast Region quota share reinsurance agreements. On February 27, 2024, CORE, a consolidated VIE, assumed 323 insurance policies from Citizens, representing approximately $38,273 in annualized premiums written. Subsequent to the reporting date, the Company notified the holders of its outstanding 4.25% Convertible Senior Notes due 2037 that the Company has elected to redeem the remaining $23,916 principal balance of the 4.25% Convertible Senior Notes. As a result of this notice, the 4.25% Convertible Senior Notes became immediately convertible into the Company’s common shares. The redemption date is March 15, 2024. The Company expects to issue approximately 397,000 shares to convert these notes. Since the notification, the Company has converted $23,380 in aggregate principal of 4.25% Convertible Senior Notes for aggregate consideration of 387,928 shares of HCI’s common stock plus cash consideration in lieu of fractional shares.
