. . . Core Efficiency Ratio1 Expense Discipline and Focused Investment 11  Q4-21 expenses were elevated due to additional costs relating to the: (i) core conversion; (ii) a year-end adjustment to the incentive plan; and (iii) expenses associated with the contribution of additional shares to the ESOP retirement plan. These expenses will moderate in Q1-22 and the Bank will realize expense savings from the branch optimization strategy. As a result, Management expects Q1-22 expenses to range between $54 million to $55 million.  Technology expense, which represents data processing, communications, and digitally focused departments, accounted for 21.2% of total core non- interest expense for the full year 2021. For the full year 2020, these costs accounted for 17.8% of core non- interest expense.  The branch optimization strategy (19 branch consolidations and 2 branch sales in December 2021 and January 2022) is expected to significantly improve the non-interest expense run-rate beginning in Q1-22.
