President’s Comments

Reflecting on the past year, Andrew J. Ryback, director, president and chief executive officer of Plumas Bancorp and Plumas Bank, stated, “United by the challenges and successes of a year in which we experienced a global pandemic, region-wide fires and power outages, and economic recession, Plumas Bank stands together with our clients and communities to move forward in recovery and with resilience.

Throughout 2020 banks stabilized the economy by acting as conduits of stimulus funds and offering deferrals and other forms of fiscal support. Plumas Bank addressed the well-being of clients, personnel, and communities by offering non-contact services via our mobile and online banking technologies, enacting optional federal initiatives for pandemic-related leave and tax deferments, and donating $15,000 to food banks in our communities which were then matched up to $10,000 by the Federal Home Loan Bank of San Francisco. To increase our resilience, Plumas Bank also installed solar panels on the Quincy branch along with a battery back-up system to allow for continuity of services in the event of power outages.”

Looking ahead, Ryback commented, “We have strengthened our reserves and continue to evaluate opportunities in light of the low-rate environment. Additionally, we continue to assess and address risks, including increased fraud and cybersecurity threats, by investing in enhanced monitoring and protection systems. With the recent approval of a second stimulus package, Plumas Bank is prepared to assist existing and new clients in navigating the Paycheck Protection Program process.”

Ryback remarked, “As we conclude our 40^th year, we would like to thank our shareholders, clients, team members, directors, and communities whose support and commitment have allowed us to deliver on our guiding principle, Plumas Bank - HERE. For Good.”

Loans, Deposits, Investments and Cash 

Gross loans increased by $90 million, or 15%, from $620 million at December 31, 2019 to $710 million at December 31, 2020. The three largest areas of growth in the Company’s loan portfolio were $69 million in commercial loans, $36 million in commercial real estate loans and $1 million in auto loans. The three largest decreases were $6 million in construction loans, $6 million in agricultural loans and $3 million in residential real estate loans. While construction loans were down from December 31, 2019 levels, we have seen a significant increase in demand for quality construction projects and expect this category to increase in the coming months. The increase in commercial loans relates to Payroll Protection Program (PPP) loans which totaled $71 million at December 31, 2020. Unamortized loan fees net of unamortized loan costs on these loans totaled $2.2 million at December 31, 2020.

We have instituted loan forbearance programs to assist borrowers with managing cash flows disrupted due to COVID-19.  As of December 31, 2020, there were 113 loan forbearance agreements outstanding which allow for the deferral of up to 6 months in payments representing approximately $37.4 million in loan balances. 

The following table presents loans under forbearance programs by loan type as of December 31, 2020 with the expected month that payments are to resume, dollars in thousands.

Total	$	12,446	$	3,767	$	1,265	$	18,903	$	972	$	37,353

Total deposits increased by $227 million from $747 million at December 31, 2019 to $974 million at December 31, 2020. We attribute much of this increase to retention of proceeds from PPP loans, a more cautious consumer, and continued growth in our customer base. The increase in deposits includes increases of $185 million in demand deposits, $60 million in savings accounts, $83 million in money market accounts, and $2 million in time deposits. These increases were partially offset by a decrease of $103 million in interest-bearing demand deposits.

During November 2020 we eliminated our interest-bearing demand deposit products transferring these accounts to either money market accounts or non-interest bearing demand accounts based on product type. We made this change in order to simplify our product offerings in light of the changes to Federal Reserve Board Regulation D which no longer limits the number of transfers or withdrawals from Money Market or Savings accounts.

At December 31, 2020, 53% of the Company’s deposits were in the form of non-interest-bearing demand deposits. The Company has no brokered deposits.

Total investment securities increased by $20 million from $159 million at December 31, 2019 to $179 million at December 31, 2020. Cash and due from banks increased by $138 million from $47 million at December 31, 2019 to $185 million at December 31, 2020.

Asset Quality

Nonperforming assets (which are comprised of nonperforming loans, other real estate owned (“OREO”) and repossessed vehicle holdings) at December 31, 2020 totaled $3.0 million, up from $2.8 million at December 31, 2019. Nonperforming assets as a percentage of total assets decreased to 0.27% at December 31, 2020 down from 0.33% at December 31, 2019. OREO declined by $304 thousand from $707 thousand at December 31, 2019 to $403 thousand at December 31, 2020. Nonperforming loans at December 31, 2020 were $2.5 million, up $0.5 million from $2.0 million at December 31, 2019. Nonperforming loans as a percentage of total loans increased to 0.36% at December 31, 2020, up from 0.33% at December 31, 2019.

The provision for loan losses increased from $1.5 million during the twelve months ended December 31, 2019 to $3.2 million during 2020. We have added a new specific pandemic qualitative factor to our allowance for loan loss calculation and have increased the qualitative factors related to economic conditions. These changes resulted in the need for additional loan loss provision during the current year. Net charge-offs totaled $516 thousand and $1.2 million during the twelve months ended December 31, 2020 and 2019, respectively. The allowance for loan losses totaled $9.9 million at December 31, 2020 and $7.2 million at December 31, 2019. The allowance for loan losses as a percentage of total loans was 1.39% at December 31, 2020 and 1.17% at December 31, 2019. Excluding PPP loans, the allowance for loan losses as a percentage of total loans at December 31, 2020 totaled 1.55%.

Shareholders’ Equity

Total shareholders’ equity increased by $15.6 million from $84.5 million at December 31, 2019 to $100.1 million at December 31, 2020. The largest component of the $15.6 million increase was earnings during the twelve-month period totaling $14.5 million. In addition, we recorded an increase in accumulated other comprehensive income of $2.7 million, from $2.0 million at December 31, 2019 to $4.7 million at December 31, 2020. Stock option activity increased shareholders’ equity by $0.3 million. During 2020 the Company paid three 12 cent per share quarterly cash dividends which had the effect of reducing shareholders’ equity by $1.9 million.

Net Interest Income and Net Interest Margin

Net interest income was $10.5 million for the three months ended December 31, 2020, an increase of $1.1 million from the same period in 2019. The increase in net interest income includes an increase of $920 thousand in interest income and a decrease of $130 thousand in interest expense. Interest and fees on loans increased by $1.3 million related to the amortization of loan fees/costs on PPP loans. During the current quarter we recorded amortization of loan fees net of loan costs on PPP loans totaling $1.6 million. This includes normal amortization on our PPP portfolio and the effect of $48 million in PPP loan forgiveness. Average loan balances increased by $125 million; however, the average yield on loans decreased by 26 basis points from 5.66% during the fourth quarter of 2019 to 5.40% during the current quarter. The reduction in loan yield includes the effect of a reduction in market rates, including a decline in the average prime rate of 1.6% largely offset by the amortization of loan fees on PPP loans as discussed above. Interest on investment securities declined by $224 thousand related to a decline in yield of 57 basis points to 1.92%. Interest on cash balances declined by $138 thousand related to a decline in the rate paid on these balances from 1.66% during the fourth quarter of 2019 to 0.11% during the current quarter. This decline in rate was partially offset by an increase in average balance of $128 million. Net interest margin for the three months ended December 31, 2020 decreased 70 basis points to 3.90%, down from 4.60% for the same period in 2019.

3

Net interest income for the year ended December 31, 2020 was $38.4 million, an increase of $841 thousand from the $37.6 million earned in 2019. Interest income increased by $322 thousand as an increase in average interest earning assets of $164 million was partially offset by a decline in the average yield on interest earning assets of 82 basis points to 4.15%. Interest expense declined by $519 thousand including declines of $133 thousand on money market accounts, $190 thousand on time deposits and $146 thousand on junior subordinated debentures. Net interest margin for the twelve months ended December 31, 2020 decreased 73 basis points to 4.02%, down from 4.75% in 2019.

Non-Interest Income/Expense

During the three months ended December 31, 2020, non-interest income totaled $2.2 million, an increase of $140 thousand from the three months ended December 31, 2019. A reduction in NSF fees of $141 thousand which we attribute primarily to the pandemic was offset by increases in other items the largest of which was an increase of $319 thousand in gain on sale of SBA loans. Gains on sale of loans were abnormally low during the fourth quarter of 2019 at $79 thousand. During the current quarter we recorded gains totaling $398 thousand.

During the twelve months ended December 31, 2020, non-interest income totaled $8.5 million, an increase of $328 thousand from $8.1 million during 2019. This increase included a one-time gain totaling $218 thousand on sale of one of the Company’s administrative buildings. A portion of this building was used as record storage for Plumas Bank while the rest of the building was available for rental to third parties. Plumas Bank has entered into a five-year lease at a cost of $1,600 per month on that portion of the property used for its record storage.

Other significant increases in non-interest income were $194 thousand in interchange fees and $477 thousand in gain on sale of SBA loans. The largest decline in non-interest income was $372 thousand in service charges which primarily was related to a decline in NSF fee income. Gains on sale of loans totaled $1.3 million during 2020 and $867 thousand in 2019.

During the three months ended December 31, 2020, total non-interest expense increased by $854 thousand from the comparable period in 2019. The largest components of this increase were increases of $445 thousand in salary and benefit costs and a decrease of $257 thousand in gains on sale of OREO. The increase in salary expense includes an increase in loan sale commissions of $119 thousand, a $127 thousand increase in salary continuation expense and a $91 thousand reduction in the deferral for loan origination fees. The increase in commissions is consistent with the increase in gain on sale of SBA 7(a) loans while the increase in salary continuation expense was related to a reduction in the discount rate used to accrue these future payments from 5% to 4%. Gains on sale of OREO declined from $266 thousand during the three months ended December 31, 2019 to $9 thousand during the current quarter. During the three months ended December 31, 2019, Plumas Bank recorded a net gain on the sale of two OREO properties totaling $266 thousand.

During the twelve months ended December 31, 2020, non-interest expense increased by $922 thousand. Increases in expense included $273 thousand in salary and benefit expense, $338 thousand in outside services fees, $266 thousand in gain on sale of OREO, $187 thousand in deposit insurance expense and $124 thousand in advertising expense. The largest reduction in non-interest expense was $210 thousand in business development expense. This reduction in business development expense which includes travel, training and entertainment expenses was mostly related to the pandemic.
