Review of Financial Position:
Total assets increased $349,723, or 16.2% annualized, to $3,233,525 at September 30, 2021, from $2,883,802 at December 31, 2020. The substantial increase in assets during the nine months was primarily due to organic growth of commercial deposits and inflows of public fund deposits. Total loans increased to $2,205,661 at September 30, 2021, compared to $2,177,982 at December 31, 2020, an increase of $27,679. Excluding PPP loans and a net decrease of $106,178 to PPP loan balances, loan growth during the first nine months of 2021 totaled $133,856, or 9.0% annualized. Investments increased $191,093 or 63.0% due to the purchase of higher yielding investment securities with a portion of our lower earning excess cash position. Despite the increase to investment balances our federal funds sold balances increased $136,500 to $319,500 at September 30, 2021 from $183,000 at December 31, 2020. Deposits increased by $403,806 or 22.2% annualized, the result of strong organic growth of core deposits from new and existing relationships, inflows of public fund deposits, and federal government stimulus payments. Interest-bearing deposits increased $313,680 while noninterest-bearing deposits increased $90,126. Deposit growth and our excess cash position were utilized to pay down short-term borrowings and payoff a matured long-term borrowing. Total borrowings at September 30, 2021 total $36,235. Total stockholders’ equity increased $10,855 or 3.4%, from $316,877 at year-end 2020 to $327,732 at September 30, 2021 due to net income, partially offset by a decrease to accumulated other comprehensive income (“AOCI”), resulting from a decrease to the unrealized gain on investment securities, and dividends paid to shareholders. For the nine months ended September 30, 2021, total assets averaged $3,002,248, an increase of $370,413 from $2,631,835 for the same period of 2020.
Investment Portfolio:
The majority of the investment portfolio is classified as available-for-sale, which allows for greater flexibility in using the investment portfolio for liquidity purposes by allowing securities to be sold when market opportunities occur. Investment securities available-for-sale totaled $461,372 at September 30, 2021, an increase of $165,461, or 55.9% from $295,911 at December 31, 2020. The increase was due to the purchase of U.S. Treasury notes, taxable and tax-exempt municipal bonds and mortgage-backed securities as we deployed a portion of excess cash into higher earning assets. A decrease in the market value of the available-for-sale portfolio of $8,409 since December 31, 2020, due to higher market rates and principal received from mortgage-backed securities and maturing bonds partially offset the increases. Investment securities held-to-maturity totaled $32,848 at September 30, 2021, an increase of $25,623 from $7,225 at December 31, 2020 due to classifying new low coupon security purchases to mitigate market value risk.
For the nine months ended September 30, 2021, the investment portfolio averaged $347,085, an increase of $47,860 or 16.0% compared to $299,225 for the same period last year. Average tax-exempt municipal bonds have increased $34,673 or 79.1% to $78,512 for the nine months ended September 30, 2021 from $43,839 during the comparable period of 2020. The increase in tax-exempt municipal bonds is due to purchases during the last twelve months with a portion of excess liquidity. The tax-equivalent yield on the investment portfolio decreased 32 basis points to 2.09% for the nine months ended September 30, 2021, from 2.41% for the comparable period of 2020. The decrease in yield is due to lower reinvestment rates for cash flow from matured and called bonds.
Securities available-for-sale are carried at fair value, with unrealized gains or losses net of deferred income taxes reported in the AOCI component of stockholders’ equity. We reported net unrealized gains, included as a separate component of stockholders’ equity of $1,017 net of deferred income taxes of $270 at September 30, 2021, and net unrealized gains of $7,660, net of deferred income taxes of $2,036, at December 31, 2020.
