Total non-interest income in the third quarter of 2024 decreased by $53,000, or 1.2%, from the prior year's third quarter and declined by $103,000, or 0.8%, in the nine months of 2024 when compared to the nine months of 2023. The slight decrease for the nine-month period is primarily attributed to the Company recognizing a $1.7 million gain in the first quarter of 2023 from AmeriServ Financial Bank selling all 7,859 shares of the Class B common stock of Visa Inc. There was no such gain during the nine-month period ending September 30, 2024. Wealth management fees improved by $205,000, or 7.2%, for the quarter and by $1.0 million, or 12.0%, for the nine months due in part to a strong performance from our Financial Services division that resulted from new business growth. Also, the increase in wealth management fees reflects the improving market conditions particularly for equity securities as major market indexes continue their ascent to record highs in 2024. Overall, the fair market value of wealth management assets totaled $2.6 billion at September 30, 2024 and increased by $218.3 million, or 9.1%, since September 30, 2023. Other income is $159,000, or 23.4%, lower for the third quarter but $590,000, or 36.5%, higher for the nine months of 2024. The variances for both time periods primarily reflect the necessary adjustments to the fair market value of an interest rate swap related risk participation agreement as well as the credit valuation adjustment to the market value of the interest rate swap contracts that the Company executed to accommodate the needs of certain borrowers while managing our interest rate risk position. These adjustments reflect the changing national interest rates which unfavorably impacted other income by $234,000 during the third quarter of 2024 but were net favorable for the nine months by $188,000. In the first quarter of 2024, other income was favorably impacted by the Company recognizing a $250,000 signing bonus that resulted from successful negotiations related to the renewal of an expiring contract with Visa.
Total non-interest expense in the third quarter of 2024 decreased by $374,000, or 3.1%, when compared to the third quarter of 2023 and decreased by $353,000, or 0.9%, during the nine months of 2024 when compared to the nine months of 2023. Salaries and employee benefits expense decreased by $914,000, or 4.1%, for the nine months of 2024 due to the net impact of certain items within this broad category. Total salaries cost was down by $641,000, or 4.1%, after the Company incurred additional salary expense in 2023 related to a strategy to consolidate certain executive level positions in the wealth management business. This is part of our previously announced earnings improvement program and was designed to lower future employee costs, which is occurring in 2024. Also, total health care cost was $459,000, or 15.9%, lower compared to last year and reflects management’s effective negotiations with our current health care provider that resulted in not having to recognize any premium costs in January 2024. These favorable items were partially offset by an increased level of incentive compensation by $343,000, or 41.2%, which corresponds to the strong performance of our wealth management division. Other expenses were $520,000, or 15.3%, higher for the nine months of 2024 when compared to the nine months of 2023. The Company was required to recognize a settlement charge in connection with its defined benefit pension plan in the second and third quarters of 2024. The amount of the 2024 charge was $410,000. A settlement charge must be recognized when the total dollar amount of lump sum distributions paid from the pension plan to retired employees exceeds a threshold of expected annual service and interest costs in the current year. It is important to note that since the retired employees have chosen to take the lump sum payments, these individuals are no longer included in the pension plan. Therefore, the Company’s normal annual pension expense will continue to be lower in the future. This was evident in 2023 and so far in 2024 as the Company has recognized a pension credit in both years. FDIC insurance increased by $265,000, or 53.5%, due to an increase in both the asset assessment base as well as the assessment rate. Data processing and IT expenses increased by $291,000, or 8.8%, in the nine months of 2024 due to additional expenses related to monitoring our computing and network environment.
Professional fees in both 2024 and 2023 were impacted by litigation and responses to the actions of an activist investor. The Company reached a Cooperation and Settlement Agreement with activist investor Driver Opportunity Partners (Driver), which was described in a Current Report on Form 8-K filed on June 14, 2024. The Company’s activist related costs declined by approximately $400,000 when the third quarter of 2024 is compared to the third quarter of 2023. Through nine months of 2024, activist related costs totaled $1.5 million compared to $2.0 million recognized through nine months of 2023. The Company does not expect to incur any additional activist related costs through the remainder of 2024.
The Company recorded income tax expense of $237,000 in the third quarter of 2024 and income tax expense of $611,000, or an effective tax rate of 18.4%, in the nine months of 2024, which compares to income tax expense of $124,000, in the third quarter of 2023 and income tax expense of $435,000, or an effective tax rate of 18.0%, for the nine months of 2023.
The Company had total assets of $1.4 billion, shareholders' equity of $108.2 million, a book value of $6.55 per common share and a tangible book value of $5.72(1) per common share on September 30, 2024. Book value per common share increased by $0.59, or 9.9%, and tangible book value per common share increased by $0.56, or 10.9% since December 31, 2023, due to a favorable adjustment for both the unrealized loss on available for sale securities and the Company’s defined benefit pension plan and the accretive repurchase of 628,003 shares of common stock from Driver. The Company continued to maintain strong capital ratios that exceed the regulatory defined well capitalized status as of September 30, 2024.
