Notes:
(1)The fair value of derivative instruments is presented on a gross basis even when derivative instruments are subject to master netting agreements. Cash collateral payable and receivable associated with derivative instruments are not added to or netted against the fair value amounts.
(2)Except for the derivative instruments described in (6), the derivative instruments which are not designated as a hedging instrument are held for trading and risk management purposes and are presented in Trading account assets and liabilities.
(3)The MUFG Group adopts hedging strategies and applies hedge accounting to certain derivative transactions entered into by certain subsidiaries. The derivative instruments which are designated as hedging instruments are presented in Other assets or Other liabilities on the accompanying condensed consolidated balance sheets.
(4)This table does not include contracts with embedded derivatives for which the fair value option has been elected.
(5)For more information about fair value measurement and assumptions used to measure the fair value of derivatives, see Note 31 to the consolidated financial statements for the fiscal year ended March 31, 2025.
(6)Other mainly includes bifurcated embedded derivatives carried at fair value, which are presented in Loans, Deposits and Long-term debt.
