Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been omitted. The condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2024 included in the Company’s Annual Report on Form 10-K.

Recently Issued Accounting Standards – Not Adopted In December 2023, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which provides qualitative and quantitative updates to the rate reconciliation and income taxes paid disclosures, among others, in order to enhance the transparency of income tax disclosures, including consistent categories and greater disaggregation of information in the rate reconciliation and disaggregation by jurisdiction of income taxes paid. The amendments in ASU 2023-09 are effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments will be applied prospectively. The ASU will result in additional income tax disclosures within the Company’s financial statements but is not expected to impact the Company’s financial condition, results of operations or cash flows. In November 2024, the FASB issued ASU No. 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures, which is intended to improve disclosures about a public business entity’s expense and provide more detailed information to investors about the types of expenses in commonly presented expense captions. The amendments in ASU 2024-03 are effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, on either a prospective or retrospective basis, with early adoption permitted. The Company is currently evaluating the impact this ASU may have on its consolidated financial statements.
