 and incorporates market-based assumptions regarding the effect of changing interest rates on the prepayment rates of certain assets and attrition rates of certain liabilities. The model also includes senior management’s projections of the future volume and pricing of each of the product lines offered by the Bancorp as well as other pertinent assumptions. The NII simulation model does not represent a forecast of the Bancorp’s net interest income but is a tool utilized to assess the risk of the impact of changing market interest rates across a range of market interest rate environments. As a result, actual results will differ from simulated results for multiple reasons, which may include actual balance sheet composition differences, timing, magnitude and frequency of interest rate changes, deviations from projected customer behavioral assumptions as well as from changes in market conditions and management strategies.

As of December 31, 2024, the Bancorp’s interest rate risk exposure is governed by a risk framework that utilizes the change in NII over 12-month and 24-month horizons under parallel and non-parallel increases and decreases in interest rates. Risk appetite thresholds are utilized for scenarios assuming a 200 bps increase and a 200 bps decrease in interest rates over 12-month and 24-month horizons. The Bancorp routinely analyzes various potential and extreme scenarios, including parallel ramps and shocks as well as steepening and other non-parallel shifts in rates, to assess where risks to net interest income persist or develop as changes in the balance sheet and market rates evolve, and employs key risk indicators and early warning indicators to monitor and manage exposures under these types of scenarios. Additionally, the Bancorp routinely evaluates its exposures to changes in the basis between interest rates.

In order to recognize the risk of noninterest-bearing demand deposit balance migration or attrition in a rising interest rate environment, the Bancorp’s NII sensitivity modeling assumes additional attrition of approximately $470 million of demand deposit balances over a period of 24 months for each 100 bps increase in short-term market interest rates. Similarly, the Bancorp’s NII sensitivity modeling incorporates approximately $470 million of incremental growth in noninterest-bearing deposit balances over 24 months for each 100 bps decrease in short-term market interest rates. The incremental balance attrition and growth are modeled to flow into and out of funding products that reprice in conjunction with short-term market rate changes.
