Such guidance is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, although early adoption is permitted. This guidance should be applied either prospectively to financial statements issued for reporting periods after the effective date of this ASU or retrospectively to any or all prior periods presented in the financial statements. While the adoption of this ASU will not have an impact on our financial position and/or results of operations, we are currently evaluating the impact this ASU may have on our consolidated financial statement disclosures, including the processes and controls around the collection of this information.
