The net interest margin increased 24 basis points to 3.80 percent for the three months ended September 30, 2022 from 3.56 percent for the three months ended June 30, 2022.

NON-INTEREST INCOME

Total non-interest income for the quarter ended September 30, 2022 decreased $0.1 million to $6.8 million from $6.9 million for the quarter ended June 30, 2022. The decrease was primarily driven by a decrease of $0.3 million in loan level derivative income, net, a decrease of $0.3 million in loan fees, and a decrease of $0.1 million in other non-interest income, partially offset by an increase of $0.6 million in gain on sales of loans and leases.

The Company recorded a provision for credit losses of $2.8 million for the quarter ended September 30, 2022, compared to $0.2 million for the quarter ended June 30, 2022. Total net recoveries for the third quarter of 2022 were $0.2 million compared to total net charge-offs of $1.2 million in the second quarter of 2022. The decrease of $1.4 million was primarily driven by a decrease in net charge-offs on equipment financing loans of $1.2 million, along with a decrease of $0.2 million on commercial loans. The ratio of net loan and lease charge-offs to average loans and leases on an annualized basis decreased to a negative 1 basis point for the third quarter of 2022 from 7 basis points for the second quarter of 2022.

The allowance for loan and lease losses represented 1.27 percent of total loans and leases at September 30, 2022, compared to 1.28 percent at June 30, 2022, and 1.48 percent at September 30, 2021.

NON-INTEREST EXPENSE

Non-interest expense for the quarter ended September 30, 2022 increased $0.1 million to $45.0 million from $44.9 million for the quarter ended June 30, 2022. The increase was primarily driven by an increase of $0.5 million in merger and acquisition expense, an increase of $0.1 million in equipment and data processing expense, and an increase of $0.1 million in occupancy expense, partially offset by a decrease of $0.5 million in compensation and employee benefits expense and a decrease of $0.1 million in professional services expense.

PROVISION FOR INCOME TAXES

The effective tax rate was 18.7 percent and 22.9 percent for the three and nine months ended September 30, 2022 compared to 25.2 percent for the three months ended June 30, 2022 and 25.0 percent and 25.1 percent for the three and nine months ended September 30, 2021. The effective tax rate for the three and nine months ended September 30, 2022 is reflective of the recognition of energy tax credits related to financing commercial investments in renewable energy platforms.

We may also make forward-looking statements in other documents we file with the Securities and Exchange Commission ("SEC"), in our annual reports to shareholders, in press releases and other written materials, and in oral statements made by our officers, directors or employees.

Forward-looking statements may differ, possibly materially, from what is included in this press release due to factors and future developments that are uncertain and beyond the scope of the Company's control.

Forward-looking statements involve risks and uncertainties which are difficult to predict. The Company's actual results could differ materially from those projected in the forward-looking statements as a result of, among others, the risks outlined in the Company's Annual Report on Form 10-K, as updated by its Quarterly Reports on Form 10-Q and other filings submitted to the SEC.
