Data and key economic assumptions, as well as the valuation's sensitivity to interest rate fluctuations, related to the Company’s mortgage servicing rights as of June 30, 2026 and December 31, 2025 are as follows:

The sensitivity calculations above are hypothetical changes and should not be considered to be predictive of future performance. Changes in fair value based on adverse changes in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, the effect of an adverse variation in a particular assumption on the fair value of the mortgage servicing rights is calculated without changing any other assumption, while in reality changes in one factor may result in changes in another, which may either magnify or counteract the effect of the change. The derivative instruments utilized by the Company, which were not included in the above sensitivities, would serve to offset the estimated impacts to fair value included in the table above. See Note 10, “Derivatives” for additional information on these derivative instruments.
As of June 30, 2026 and December 31, 2025, the Company held mortgage escrow deposits totaling $113,556 and $69,055, respectively, related to loans sold with servicing retained.
