The figures included in the tables above represent projections that were computed based upon certain assumptions including loan prepayment rates and deposit decay rates. These assumptions are inherently uncertain and, as a result, we cannot precisely predict the impact of changes in interest rates. Actual results may differ significantly due to timing, magnitude and frequency of interest rate changes and changes in market conditions. Compared to 2023, the simulations showed decreased interest rate sensitivity in rising rate scenarios which was driven by an increase in floating rate commercial loans. Additionally, decreased interest rate sensitivity was driven by decreased deposit beta assumptions that were revised after most current down rate environment. 

When assessing our interest rate sensitivity, analysis of historical trends indicates that loans will prepay at various speeds (or annual rates) depending on the variance between the weighted average portfolio rates and the current market rates. In preparing the table above, the following assumptions were used: (i) adjustable-rate mortgage loans will prepay at an annual rate of 8% to 23%; (ii) fixed-rate mortgage loans will prepay at an annual rate of 6% to 40%, depending on the type of loan; (iii) commercial loans will prepay at an annual rate of 10% to 30%; and (iv) consumer loans held by Northwest Bank will prepay at an annual rate of 15% to 25%. In regards to our deposits, it has been assumed that (i) fixed maturity deposits will not be withdrawn prior to maturity; (ii) a significant majority of money market accounts will re-price immediately; (iii) savings accounts will gradually re-price over three years; and (iv) checking accounts will re-price either when the rates on such accounts re-price as interest rate levels change, or when deposit holders withdraw funds from such accounts and select other types of deposit accounts, such as certificate accounts, which may have higher interest rates. For purposes of this analysis, management has estimated, based on historical trends, that $584 million, or 22%, of our interest-bearing demand accounts and $409 million, or 19%, of our savings deposits are interest sensitive and may re-price in one year or less, and that the remainder may re-price over longer time periods.

The above assumptions are annual percentages based on remaining balances and should not be regarded as indicative of the actual prepayments and withdrawals that we may experience. Moreover
