The Company’s efficiency ratio was 48.7% for the three months ended September 30, 2023, as compared to 49.3% in 2022, despite our significant increase in resources including, but not limited to, people and technology to support growth, risk management, and compliance. This improvement is a result of our continued revenue growth driven by our core national platforms. These national platforms have benefited from our investments in technology, digital marketing, employees, and other branchless infrastructure that support our industry leading returns.
The effective tax rate was 26.0% for the third quarter of 2023, as compared to 26.5% for the same period in 2022. The effective tax rate in the third quarter of 2023 was impacted by certain discrete tax benefits related to share-based compensation.
Year to Date Earnings
Net income for the nine months ended September 30, 2023 was $31.1 million, or $3.74 per diluted share, compared to $19.4 million, or $2.37 per diluted share for the same period in 2022. Returns on average assets and equity for the nine months ended September 30, 2023 were 3.00% and 24.09%, respectively, compared to 2.14% and 17.88% for the same period of 2022. Excluding the year-to-date pretax gain of $5.3 million on our Litify investment and the $1.3 million equity method loss on our investment in a third party sponsored NFL consumer post settlement loan fund, adjusted(1) net income, diluted earnings per share, return on average assets, and return on average common equity for the nine months ended September 30, 2023 would have been $28.2 million, $3.39, 2.71% and 21.82%, respectively.
Net interest income for the nine months ended 2023 increased $20.1 million, or 49.0%, to $61.1 million, due to growth in average interest earning assets (funded with core deposits) totaling $175.6 million, or 15.0%, to $1.3 billion as well as a 139 basis point increase in our net interest margin to 6.08% when compared to the same period in 2022. Our net interest margin was positively impacted by growth in higher yielding variable rate commercial loans and increases in short-term interest rates. The average yield on loans increased 160 basis points to 7.68%, primarily driven by higher yielding variable rate commercial loan growth (approximately 60% of our portfolio is tied to prime). Average loans for the nine months ended September 30, 2023 increased $188.1 million, or 22.8%, to $1.0 billion when compared to the nine months ended September 30, 2022, primarily due to growth in our national commercial lending platform and, to a lesser extent, our regional real estate loans. Average securities for the nine months ended September 30, 2023 increased $6.8 million to $208.3 million as yields increased 33 basis points to 2.30% primarily due to reinvestment of portfolio cash flows into securities at current market interest rates, increasing interest income $606 thousand to $3.6 million for the nine months ended September 30, 2023. The movement in short-term interest rates increased yields and interest income on our reverse repurchase agreements and interest earning cash balances. Our deposit cost-of-funds, excluding demand deposits, increased 78 basis points when comparing the first nine months of 2023 to the same period in 2022 due to increases in short-term interest rates as well as management pro-actively increasing rates on IOLTA or escrow accounts in the various states where we operate. We anticipate additional increases in our cost-of-funds in the future due to the current short-term interest rate environment. These increases may negatively impact our net interest margin in future quarters.
The provision for credit losses was $3.0 million for the nine months ended September 30, 2023, an $885 thousand increase from the same period in 2022. The increase in the allowance as a percentage of loans was general reserve driven considering loan growth and qualitative factors associated with the current uncertain economic environment including, but not limited to, its potential impact on the New York metro commercial real estate market.
Noninterest income increased to $23.5 million for the nine months ended September 30, 2023, as compared to $18.1 million in same period in 2022. Payment processing income was $16.9 million for the nine months ended September 30, 2023, a $611 thousand increase from the same period in 2022. Payment processing volumes and transactions for the credit and debit card processing platform increased $3.8 billion, or 18.6%, to $24.5 billion and 61.0 million, or 15.4%, to 457.0 million transactions, respectively, for the nine months ended September 30, 2023 as compared to the same period in 2022. These increases were due to the expansion of sales channels through ISOs, the increased number of merchants, volume increases, and were facilitated by our focus on technology and other resources in the payments vertical. ASP fee income increased $375 thousand, or 24.8%, to $1.9 million for the nine months ended September 30, 2023 as average balances of off-balance sheet sweep funds and the increases in short-term interest rates directly impact fee income. In February 2023, Litify was reorganized into a partnership and an unrelated third party acquired majority ownership in the reorganized entity. As an equity holder and party to the reorganization and sale transaction, the Company’s partnership interests were exchanged for cash and undiscounted noncash consideration of approximately $8.3 million. As a result, the Company recognized a gain of $5.3 million in 2023. As previously noted, the Company also recognized an equity method loss of $1.3 million on its investment in a third party sponsored NFL consumer post settlement loan fund in 2023.
