Material Distribution Relationships	Material Distribution Relationships Ivantage Select Agency, Inc. The Company is a party to an insurance agency master agreement with Ivantage Select Agency, Inc. (“ISA”), an affiliate of Allstate Insurance Company (“Allstate”), pursuant to which the Company has been authorized by ISA to appoint Allstate agents to offer our FNIC homeowners insurance products to consumers in Florida. As a percentage of the total homeowners premiums we underwrote, 17.4% and 19.6% were from Allstate’s network of Florida agents, for the three months ended March 31, 2022 and 2021, respectively. SageSure Insurance Managers, LLC The Company is a party to a managing general underwriting agreement with SageSure Insurance Managers, LLC (“SageSure”) to facilitate our FNIC homeowners business outside of Florida. As a percentage of the total homeowners premiums, 11.7% and 24.5% of the Company’s premiums were underwritten by SageSure, for the three months ended March 31, 2022 and 2021, respectively. As part of our partnership with SageSure, previously we entered into a profit share agreement, whereby we shared 50% of net profits of this line of business through June 30, 2020, as calculated per the terms of the agreement, subject to certain limitations, which included limits on the net losses that SageSure could realize. The limit was based on the amount of inception to date profits within the profit share agreement. In addition, refer to Note 5 for information regarding a fully collateralized quota-share treaty on this book of business that became effective July 1, 2020.
Basis of Presentation	Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”). The consolidated financial statements include the accounts of FNHC and its wholly-owned subsidiaries and all entities in which the Company has a controlling financial interest and any variable interest entity (“VIE”) of which the Company is the primary beneficiary. The Company’s management believes the consolidated financial statements reflect all material adjustments, including normal recurring adjustments, necessary to fairly state the financial position, results of operations and cash flows of the Company for the periods presented. All significant intercompany accounts and transactions have been eliminated in consolidation. The Company identifies a VIE as an entity that does not have sufficient equity to finance its own activities without additional financial support or where the equity investors lack certain characteristics of a controlling financial interest. The Company assesses its contractual, ownership or other interests in a VIE to determine if the Company’s interest participates in the variability the VIE was designed to absorb and pass onto variable interest holders. The Company performs an ongoing qualitative assessment of its variable interests in a VIE to determine whether the Company has a controlling financial interest and would therefore be considered the primary beneficiary of the VIE. If the Company determines it is the primary beneficiary of a VIE, the Company consolidates the assets and liabilities of the VIE in its consolidated financial statements.

Accounting Estimates and Assumptions	Accounting Estimates and Assumptions The Company prepares the accompanying consolidated financial statements in accordance with GAAP, which requires management to make estimates and assumptions about future events that affect the amounts reported in the financial statements and accompanying notes. Future events and their effects cannot be determined with absolute certainty. Therefore, the determination of estimates requires the exercise of judgment. Actual results may materially differ from those estimates. Similar to other property and casualty insurers, the Company’s liability for loss and loss adjustment expenses ("LAE") reserves, although supported by actuarial projections and other data, is ultimately based on management’s reasoned expectations of future events. Although considerable variability is inherent in these estimates, the Company believes that the liability and LAE reserve is adequate. The Company reviews and evaluates its estimates and assumptions regularly and makes adjustments, reflected in current operations, as necessary, on an ongoing basis.
Recently Issued Accounting Pronouncements, Adopted	Recently Issued Accounting Pronouncements, Adopted In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") 2020-1, Accounting for Equity Securities and Equity Investments, which clarifies the interaction between accounting standards related to equity securities (Topic 321), equity method investments (Topic 323), and certain derivatives (Topic 815). The update clarifies that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. The Company adopted the guidance effective January 1, 2022, which did not have any impact on the Company’s consolidated financial condition, results of operations, or disclosures. In August 2020, the FASB issued ASU 2020-6, Accounting for Convertible Instruments and Contracts in an Entity's Own Equity ("ASU 2020-6"), which simplifies an issuer's accounting for convertible instruments by eliminating two of the three models in the current guidance that requires separate accounting for certain embedded conversion features. The new guidance simplifies the settlement assessment that entities are required to perform to determine whether a contract qualifies for equity classification. ASU 2020-6 requires entities to use the if-converted method for all convertible instruments in the diluted earnings per share calculation and include the effect of potential share settlement (if the effect is more dilutive) for instruments that may be settled in cash or shares, except for certain liability-classified share-based payment awards. This new guidance requires disclosures about events that occur during the reporting period and cause conversion contingencies to be met and about the fair value of convertible debt at the instrument level, among other things. The Company adopted the guidance effective January 1, 2022, which did not have any impact on the Company’s consolidated financial condition or results of operations.
