Net Interest Income
Net interest income for the three months ended December 31, 2021 was $8,765, an increase of $163, or 1.89% compared to $8,602 for the three months ended September 30, 2021, and an increase of $272, or 3.20%, compared to $8,493 for the three months ended December 31, 2020. The net interest margin (“NIM”) was 2.85% for the current quarter, an increase of 11 bps from the linked quarter NIM of 2.74%. The NIM increased 21 bps from 2.64% compared to the same period in 2020.
The linked quarter increase in NIM is a result of management strategically reallocating the mortgage-back securities portfolio into securities that are less likely to prepay, such as higher yielding municipal investments.
Net interest income for the twelve months ended December 31, 2021 increased $360, or 1.09% to $33,494 from $33,134 for the same period in 2020. The year-to-date NIM was 2.60% as of December 31, 2021 compared to 2.53% at September 30, 2021 and 2.72% for the same period in 2020.
Margin compression for the year was a result of continued low interest rates decreasing the yield on loans and the securities portfolio coupled with negative loan growth; partially offset by lower costs of interest-bearing deposits.
Credit Quality
The provision for loan losses for the three months ended December 31, 2021 was $122. The provision was primarily driven by reclassifying the remaining acquired loan balances from the Charter Bank merger to loans held for investment. Other factors that affected the provision for the quarter were qualitatively applied due to the continued affects of the COVID-19 pandemic. Allowance to total loans held for investment was 0.79% and 0.73% at December 31, 2021 and 2020 respectively, representing a level management considers commensurate with the present risk in the loan portfolio.
As stated in the highlights, the Company’s non-performing assets decreased by $616, or (8.71%), to $6,455 at December 31, 2021 compared to $7,071 at September 30, 2021 and decreased $5,200 or (44.62%), from $11,655 at December 31, 2020. The decrease during the fourth quarter of 2021 reflects the writedown of $524 of other real estate owned (“OREO”) properties. The year-over-year decrease is the result of the foreclosure of one non-accrual impaired loan subsequently offset with total sales of $2,934 of OREO properties during the year coupled with writedowns of $914 for the year as well.
Net charge-offs total $928 in the fourth quarter. Year-to-date net charge-offs totaled $1,631, or 0.26% of average loans for 2021 compared to 0.08% for 2020. The increase in the net charge-offs for the fourth quarter and year-to-date was primarily driven by one impaired relationship that was fully reserved for in the third quarter of 2021.
Noninterest Income
Noninterest income decreased for the three months ended December 31, 2021, by $621, or (18.85%) compared to the three months ended September 30, 2021 and decreased by $299 or (10.06%) compared to the same period in 2020.
