 that are sourced using a combination of third-party prepayment models and internal historical experience, terminal maturity for non-maturity deposits, decay attrition, and pricing sensitivity derived from the Company's data and other internally-developed analysis and models. These assumptions are reviewed at least annually and are adjusted periodically to reflect changes in market conditions and the Company's balance sheet composition. As simulated model results are based on a number of assumptions outlined above, including forecasted market conditions, actual amounts may differ significantly from the projections set forth below should market conditions vary from the underlying assumptions. 

This simulation model assesses the changes in the market value of interest rate sensitive financial instruments that would occur in response to an instantaneous and sustained increase or decrease (shock) in market interest rates. The Company continues to evaluate the scenarios that are presented as interest rates change and will update these scenario disclosures as appropriate.

The following table shows the Company's projected change in EVE for this set of rate shocks at March 31, 2025:

At March 31, 2025, the Company's EVE exposure related to these hypothetical changes in market interest rates was within the Company's current limits. 

Derivative Contracts. In the normal course of business, the Company uses derivative instruments to meet the needs of its customers and manage exposure to fluctuations in interest rates. For additional discussion on how derivatives in a hedging relationship (fair value hedges) are used to manage the Company's interest rate risk, see "Note 12. Derivatives and Hedging Activities" to the Unaudited Consolidated Financial Statements.
