Prior to the freeze of all future benefit accruals and accrual of benefit service as of December 31, 2020, the service cost component was recorded on our consolidated income statements as salaries and employee benefits in noninterest expense. All other components other than service costs are recorded in other noninterest expense.

During the three months ended June 30, 2021, we updated our expected long-term rate of return on plan assets for the Retirement Plan and the Acquired Retirement Plan from 6.50% to 6.125%.
