On December 4, 2023, the FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures ("ASU 2023-09"). ASU 2023-09 amends ASC 740, Income Taxes to expand income tax disclosures and requires that the Company disclose (i) the income tax rate reconciliation using both percentages and reporting currency amounts;  (ii) specific categories within the income tax rate reconciliation; (iii) additional information for reconciling items that meet a quantitative threshold; (iv) the composition of state and local income taxes by jurisdiction; and (v) the amounts of income taxes paid disaggregated by jurisdiction.  The Company adopted ASU 2023-09 for the year ended December 31, 2025 on a prospective basis.

In November 2024, The FASB issued ASU No. 2024-03, Disaggregation of Income Statement Expenses, which requires more detailed information about the types of expenses included in certain expense captions presented on the consolidated statements of operations. Additionally, this amendment requires the disclosure of a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively and the disclosure of the total amount of selling expenses. The new standard is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. We are currently evaluating the impact of adoption on our financial disclosures.

In July 2025, the FASB issued ASU 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which allows for a practical expedient election to assume that current conditions as of the balance sheet date do not change for the remaining life of the asset in the development of a reasonable and supportable forecast as part of estimating expected credit losses. The new standard is effective for annual periods beginning after December 15, 2025, with early adoption permitted. We are currently evaluating the impact of adoption on our consolidated financial statements.

In September 2025, the FASB issued ASU No. 2025-06, Targeted Improvements to the Accounting for Internal-Use Software, which removes references to project stages and clarifies the timing of capitalizing costs based on certain thresholds. Additionally, this amendment requires certain disclosures in the notes to the financial statements regardless of financial statement presentation of software costs. The new standard is effective for annual periods beginning after December 15, 2027, and interim periods within those annual reporting periods with early adoption permitted. We are currently evaluating the impact of adoption on our consolidated financial statements and disclosures.
