Recently issued accounting pronouncements

The Company continually assesses new accounting pronouncements to determine their applicability. When it is determined that a new accounting pronouncement affects the Company’s financial reporting, the Company undertakes a study to determine the consequences of such change to its Consolidated Financial Statements and ensures that there are proper controls in place to ensure that the Company’s Consolidated Financial Statements properly reflect the change.

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 expands existing income tax disclosures for rate reconciliations by requiring disclosure of certain specific categories and additional reconciling items that meet quantitative thresholds and expands disclosures for income taxes paid by requiring disaggregation by certain jurisdictions. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. The Company adopted the updated guidance for the year ended December 31, 2025, and applied the new disclosure requirements prospectively to the current annual period. Prior period disclosures have not been adjusted to reflect the new disclosure requirements.

In December 2023, the FASB issued ASU No. 2023-08, Intangibles - Goodwill and Other - Crypto Assets (Subtopic 350-60): Accounting for and Disclosure of Crypto Assets (“ASU 2023-08”), which establishes accounting guidance for crypto assets meeting certain criteria. Bitcoin meets this criteria. The amendments require crypto assets meeting the criteria to be recognized at fair value with changes recognized in net income for each reporting period. Upon adoption, a cumulative-effect adjustment is made to the opening balance of retained earnings as of the beginning of the annual reporting period of adoption. ASU 2023-08 is effective for fiscal years beginning after December 15, 2024, including interim periods within those fiscal years. Early adoption is permitted. The Company elected to early adopt ASU 2023-08 for the year ended December 31, 2023. As a result of the adoption, the Company recorded a cumulative effect adjustment to its Accumulated deficit balance of approximately $6.0 million as of January 1, 2023, as a result of recognizing its bitcoin held as of January 1, 2023, at fair value.
