Q3 2023
The provision in the current quarter was primarily due to an increase in the reserve evaluated on a collective basis, driven by a small number of large new loans and renewals and credit quality deterioration of certain commercial real estate (CRE) and commercial and institutional (C&I) loans, partially offset by a net improvement in the overall macroeconomic outlook. The reserve evaluated on a collective basis relates to pooled financial assets sharing similar risk characteristics.
Q2 2023
The release of credit reserves in the prior quarter was primarily due to a decrease in the reserve evaluated on a collective basis, driven by improved credit quality in certain C&I and certain CRE loans, partially offset by expectations for higher economic stress at the time in the CRE market, particularly Office CRE.
Q3 2022
The provision in the prior-year quarter was primarily due to an increase in the collective basis reserve, driven by a weaker macroeconomic outlook at the time, partially offset by improvements in credit quality mainly within the C&I portfolio.

RECONCILIATION TO FULLY TAXABLE EQUIVALENT
The following table presents a reconciliation of interest income, net interest income, net interest margin, and total revenue prepared in accordance with generally accepted accounting principles to such measures on an FTE basis, which are non-generally accepted accounting financial measures. Net interest margin is calculated by dividing annualized net interest income by average interest-earning assets. Management believes this presentation provides a clearer indication of these financial measures for comparative purposes. When adjusted to an FTE basis, yields on taxable, nontaxable and partially taxable assets are comparable; however, the adjustment to an FTE basis has no impact on net income.
