[1] In fourth quarter 2025, we changed the presentation of certain items on our consolidated balance sheet, including trading assets and liabilities and short-term borrowings, with corresponding changes to our consolidated statement of income. In connection with these changes, we reclassified the gains (losses) related to our physical commodities inventory, including the related hedging impacts, from other noninterest income to net gains from trading activities. Prior period balances have been revised to conform with the current period presentation. For additional information, see Note 1 (Summary of Significant Accounting Policies).
