On December 16th, according to The Bitcoin Historian, an editor at Bitcoin Magazine, the fair value accounting standards for Bitcoin by the Financial Accounting Standards Board (FASB) officially took effect. Previously, companies could only measure their held Bitcoin assets by historical cost and could not reflect their market value growth. The new standard allows companies to use fair value measurement methods to more accurately reflect the actual value of their Bitcoin assets, which will reduce accounting barriers for companies to include Bitcoin on their balance sheets. MicroStrategy founder Michael Saylor previously stated that FASB has officially passed fair value accounting rules for Bitcoin, which will apply to fiscal years beginning after December 15, 2024. This improvement will encourage companies to adopt Bitcoin as a reserve asset.
