The cumulative loss rate used as the basis for the estimate of credit losses is comprised of the Company's historical loss experience from December 31, 2011 to June 30, 2025. As of June 30, 2025, the Company expects that the markets in which it operates will experience minimal changes to economic conditions, stable trend in unemployment rate, and a level trend of delinquencies. Management adjusted historical loss experience for these expectations. No reversion adjustments were necessary, as the starting point for the Company's estimate was a cumulative loss rate covering the expected contractual term of the portfolio. While there are many factors that go into the calculation of the allowance for credit losses, the change in the balances from June 30, 2024 to June 30, 2025 is largely attributed to three commercial real estate non-owner occupied relationships individually evaluated and specifically reserved for, loss ratio trends of commercial real estate non-owner occupied, and increased loan balances. These factors were partially offset by adjustments made to the maximum loss rates that anchor the qualitative factors and adjustments to the Portfolio Composition and Growth qualitative factor.
