Risk-adjusted Capital Amounts and Ratios
The risk-adjusted capital amounts and ratios, and leverage ratios, of MUFG, MUFG Bank and Mitsubishi UFJ Trust and Banking presented in the following table are based on amounts calculated in accordance with Japanese GAAP as required by the FSA.
Starting from the fiscal year ended March 31, 2025, the fiscal year of Krungsri has been changed from the previous January to December period to an April to March period for consolidation purposes. In connection with the change, the amount of retained earnings under Japanese GAAP which is included in MUFG's Common Equity Tier 1 capital component as of March 31, 2025, reflects Krungsri's relevant amount for the fifteen months ended March 31, 2025.

Notes:
(1)Effective March 31, 2016, the FSA’s capital conservation buffer, countercyclical buffer and G-SIB surcharge requirements became applicable to Japanese banking institutions with international operations conducted through foreign offices. As a result, in addition to the 4.50% minimum Common Equity Tier 1 capital ratio, MUFG is required to maintain a capital conservation buffer of 2.5% and a G-SIB surcharge of 1.5% as of March 31, 2025 and 2026, respectively, and the countercyclical buffer of 0.16% and 0.18% as of March 31, 2025 and 2026, respectively.
(2)Effective March 31, 2023, the G-SIB leverage ratio buffer requirement became applicable to Japanese banking institutions with international operations conducted through foreign offices. As a result, in addition to the 3.00% minimum leverage ratio, MUFG is required to maintain a G-SIB leverage ratio buffer of 0.75% as of March 31, 2024. On and after April 1, 2024, the minimum leverage ratio has been raised to 3.15% and MUFG is required to maintain a G-SIB leverage ratio buffer of 0.75% plus 0.05%.
