In the opinion of management, all normal recurring adjustments necessary for a fair presentation of the consolidated financial position and results of operations for the periods presented have been included. All significant intercompany balances and transactions have been eliminated in consolidation. Prior period amounts are reclassified when necessary to conform to the current year’s presentation. These reclassifications did not have any effect on the consolidated operating results or financial position of the Company. The consolidated operating results and financial position of the Company for the three months ended and as of March 31, 2024, are not necessarily indicative of the results of consolidated operations and financial position that may be expected in the future. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates that are particularly susceptible to material change in the near term relate to the determination of the allowance for credit losses, fair value of financial instruments, the valuation of deferred tax assets, and impairment of goodwill. Actual results could differ from those estimates. For additional information and disclosures required under GAAP, reference is made to the Company’s Annual Report on Form 10-K for the period ended December 31, 2023.
