2Information for mortgage-backed securities, collateralized mortgage obligations, and small business administration securities reflect weighted average life, including anticipated future prepayments.

As of December 31, 2024, our investment securities portfolio was comprised of securities with an average remaining duration of approximately 4.83 years, which does not consider the impact of the interest rate swaps that hedge a portion of our available-for-sale portfolio.

We continually evaluate our investment securities portfolio in response to established asset/liability management objectives, changing market conditions that could affect profitability, and level of interest rate risk to which we are exposed. These evaluations may cause us to change the level of funds deployed into investment securities, change the composition of our investment securities portfolio, and change the proportion of investments made into the available-for-sale and held-to-maturity investment categories.

These securities carry the explicit and/or implicit guarantee of the U.S. government and have a long history of zero credit loss. Total gross unrealized losses were primarily attributable to changes in interest rates, relative to when the investment securities were purchased, and not due to the credit quality of the investment securities. At December 31, 2024, we had the intent and ability to hold the investment securities that were in an unrealized loss position and it is not more likely than not
