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.
