The wealth management segment’s net income contribution was $547,000 in the third quarter and $1,510,000 for the first nine months of 2020 which was $70,000 higher than the third quarter of 2019 and $145,000 higher for the nine-month time period. The increase is due to wealth management fees increasing in both time periods as this segment was positively impacted by management’s effective execution of managing client accounts. The entire wealth management division has been resilient and performed well in spite of the volatility of the markets and a major market value decline that occurred in late March. The wealth management division also benefitted from a lower level of meals & travel related expenses due to travel restrictions from the pandemic. Slightly offsetting these favorable items were higher levels of professional fees, incentive compensation and equipment costs. Overall, the fair market value of trust assets under administration totaled $2.290 billion at September 30, 2020, an increase of $147 million, or 6.9%, from the September 30, 2019 total of $2.143 billion.
The investment/parent segment reported a net loss of $1,978,000 in the third quarter of 2020 and a net loss of $5,392,000 in the first nine months of 2020 which is a greater loss by $399,000 for the quarter and by $765,000 for the nine-month period. The increased loss was due to securities interest income decreasing by a higher amount than the decrease to total short term FHLB borrowings interest expense. Also, short-term investment interest income decreased for the quarter and only demonstrated a slight increase for the nine months even though the Company experienced exceptionally strong growth in its liquidity position between years from the significant influx of deposits that resulted from the government stimulus programs. However, the yield on commercial paper decreased significantly during the third quarter and resulted in reduced interest income. In 2019, this segment benefited from an investment security sale gain and there was no such gain in 2020, as discussed previously. Finally, the greater net loss at the investment/parent segment results from higher salaries and group insurance expense.
…..BALANCE SHEET…..The Company’s total consolidated assets were $1.26 billion at September 30, 2020, which increased by $86.9 million, or 7.4%, from the December 31, 2019 asset level. This change was related, primarily, to increased levels of cash and cash equivalents and loans. Specifically, short-term investments increased $16.2 million, or 430.6%, as the Company utilized the liquidity created by the significant influx of deposits, that resulted from the government stimulus programs, to purchase commercial paper. In addition, loans, net of unearned fees, and loans held for sale increased by $61.8 million, or 7.0%, as a result of the Company’s participation in the Paycheck Protection Program (PPP) and higher levels of residential mortgage loan production. In addition, total investment securities increased $2.7 million, or 1.5%, as the market value of the available for sale securities increased since year-end, accrued interest income receivable increased $2.3 million, or 65.9%, due to the loan modifications executed related to COVID-19 which deferred the payment of interest on certain loans for a period of three to six months, and other assets increased $2.6 million, or 42.2%, driven by an increase in the fair value of the interest rate swap assets.
Total deposits increased by $81.7 million, or 8.5%, in the first nine months of 2020. This robust growth is the result of consumers’ behavior to, 1) deposit their PPP funds into deposit accounts, 2) deposit government stimulus checks into the bank, and 3) keep higher balances in their accounts since they are not able to spend as much as they otherwise would because of the COVID-19 pandemic’s impact to the economy and our community. As of September 30, 2020, the 25 largest depositors represented 20.7% of total deposits, which is a slight decrease from December 31, 2019 when it was 20.9%. Total borrowings have increased by $4.1 million, or 4.1%, since year-end 2019. The increase was driven, primarily, by a higher level of FHLB term advances which totaled $74.3 million at September 30, 2020, an increase of $20.7 million, or 38.5%. The increase in FHLB term advances more than offset the decrease in short-term borrowings. Specifically, short-term borrowings decreased by $16.5 million, or 73.7%, and totaled $5.9 million. The Company has utilized the FHLB term advances to help manage interest rate risk and the lower U.S. Treasury yield curve and its flat shape allowed the Company to prudently extend borrowings.
The Company’s total shareholders’ equity increased by $4.8 million over the first nine months of 2020 due to the retention of earnings more than offsetting our common stock dividend payments to shareholders and the impact of our common stock buyback program. Additionally, the improved value of the investment securities portfolio had a positive impact on accumulated other comprehensive loss.
