(1)During the fourth quarter of 2021, the Company enhanced its segment allocation methodology related to the fair values of interest rate and commodity derivative contracts, which are included in noninterest income. These fair values that were previously allocated to the “Commercial Banking” segment, have been reclassified between “Consumer and Business Banking” and “Commercial Banking.” Prior years’ balances have been reclassified to conform to the 2021 presentation.
