26 Asset - sensitive Interest Rate Risk Profile Citizens & Northern uses a simulation model to calculate the potential effects of interest rate fluctuations on net interest income and the market value of portfolio equity. The model makes estimates, at each level of interest rate change, regarding cash flows from principal repayments on loans and mortgage - backed securities and call activity on other investment securities. Actual results could vary significantly from these estimates, which could result in significant differences in the calculations of projected changes in net interest income and market value of portfolio equity.
