Balance Sheet:
Total assets of $2.02 billion as of December 31, 2021, represented a decrease of $34.1 million, or 2%, compared to $2.05 billion at September 30, 2021 and an increase of $109.2 million, or 6%, compared to $1.91 billion at December 31, 2020. The decrease in total assets from the third quarter of 2021 was primarily due to a reduction in liquidity resulting from the seasonal outflow of deposits related to tax planning distributions made by certain commercial clients, partially offset by growth in the loan and investment portfolios. The year-over-year increase in total assets was primarily due to excess liquidity generated from growth in the deposit portfolio as the result of funding additional PPP loans combined with organic growth.
Total gross loans increased by $74.7 million, or 6%, to $1.38 billion at December 31, 2021 compared to $1.30 billion at September 30, 2021 and increased by $7.6 million, or 1%, compared to $1.37 billion at December 31, 2020.
During the fourth quarter of 2021, commercial and real estate other loans increased by $46.1 million and $33.0 million, respectively, due to organic growth. Additionally, during the fourth quarter of 2021 the Company purchased, net of discount, $22.7 million of residential solar loans. Partially offsetting these increases within the total loan portfolio, SBA loans decreased by $25.7 million primarily due to PPP loan forgiveness.
Year-over-year, commercial and real estate other loans increased by $59.7 million and $146.5 million, respectively, due to organic growth. The Company also purchased two portfolios of residential solar loans totaling approximately $42.7 million, net of discount. Partially offsetting these increases within the total loan portfolio, SBA loans decreased by $236.2 million primarily due to PPP loan forgiveness.
As a result of the CARES Act PPP, which was launched in April 2020 and re-launched in January 2021, the Company funded approximately $491.3 million in loans. Approximately $418.8 million of those balances have been granted forgiveness by the SBA as of December 31, 2021.
Total deposits decreased by $61.9 million, or 4%, to $1.68 billion at December 31, 2021, from $1.74 billion at September 30, 2021 and increased by $147.9 million, or 10%, over $1.53 billion at December 31, 2020. The decrease in total deposits from the end of the third quarter of 2021 was primarily due to a reduction in noninterest- bearing demand deposits of $19.4 million and a reduction in money market and savings deposits of $32.6 million.
Compared to the same period last year, deposit growth was primarily concentrated in noninterest-bearing demand and money market deposits as the result of funding PPP loans combined with organic growth. Noninterest-bearing deposits, consisting primarily of commercial business operating accounts, represented 46% of total deposits at December 31, 2021, compared to 45% at September 30, 2021 and 44% at December 31, 2020.
As of December 31, 2021, the Company had borrowing arrangements, excluding junior subordinated debt securities, of $106.4 million compared to $79.5 million at September 30, 2021 and $189.0 million as of December 31, 2020. The increase in borrowings during the fourth quarter of 2021 was comprised primarily of a $50.0 million short-term FHLB advance, partially offset by a $23.1 million reduction in PPPLF activity.
Asset Quality:
The provision for loan losses increased to $504,000 for the fourth quarter of 2021 compared to $300,000 for the third quarter of 2021 and decreased from $700,000 for the fourth quarter of 2020. Net loan recoveries in the fourth quarter of 2021 were $6,000, or 0.00% of gross loans, compared to net recoveries of $31,000, or 0.00% of gross loans, in the third quarter of 2021 and net recoveries of $26,000, or 0.00% of gross loans, in the fourth quarter 2020.
Non-performing assets (“NPAs”) to total assets of 0.01% at December 31, 2021 compared to 0.06% at September 30, 2021 and 0.01% at December 31, 2020, with non-performing loans of $232,000, $1.2 million, and $234,000 respectively, on those dates. The decrease in NPAs at December 31, 2021 compared to the September 30, 2021 primarily related to one commercial real estate loan that was paid off in full by the borrower.
