President’s Comments

Andrew J. Ryback, director, president and chief executive officer of Plumas Bancorp and Plumas Bank, commented, “The Board of Directors, executives and I are extremely pleased to report that the Company delivered record earnings for all four quarters in 2018. Our performance was driven by strong loan and deposit growth. We also maintained excellent asset quality metrics and continued our focus on improving overall efficiency. These operating results enhanced shareholder value in 2018 by increasing tangible book value, providing a return on average equity significantly higher than peer institutions, and the payment of a notable semi-annual dividend.”

Ryback continued, “2018 was a productive year for our Company. We successfully executed on our strategic priorities throughout the year, most notably our technology initiatives and our expansion into Carson City, Nevada and the Sierra region. All of this was accomplished while continuing to invest in our team members and our communities.”

Ryback concluded, “With our solid level of capital and our robust earnings momentum, we believe that Plumas Bancorp is well positioned to continue its strong growth and high returns in 2019.”

Loans, Deposits, Investments and Cash 

Gross loans increased by $79.6 million, or 16%, from $486.6 million at December 31, 2017 to $566.2 million at December 31, 2018. The increase in loan balances includes $31.4 million in commercial real estate loans, $16.7 million in automobile loans, $15.0 million in construction and land development loans, $10.3 million in agricultural loans and $9.9 million in commercial loans. These increases were partially offset by declines in other loan categories the largest of which was a decrease of $3.3 million in equity lines of credit.

Total deposits increased by $63.9 million, or 10%, from $662.7 million at December 31, 2017 to $726.6 million at December 31, 2018. The increase in deposits includes $45 million in deposits at our Carson City, Nevada branch which we purchased from Mutual of Omaha Bank on October 26, 2018. At December 31, 2018, 42% of the Company’s deposits were in the form of non-interest-bearing demand deposits.

The increase in deposits of $63.9 million includes increases of $22.0 million in money market accounts, $21.8 million in demand deposits, $10.9 million in time deposits, $5.9 million in interest-bearing demand deposits and $3.3 million in savings accounts. The increase in time deposits relates to the Carson City branch acquisition as does much of the increase in money market accounts. The average rate paid on the Carson City money market and time deposits exceeds that which Plumas Bank pays in other markets and we would expect some runoff on these accounts as they reprice over time. The Company has no brokered deposits.

Total investment securities increased by $34.0 million to $171.5 million at December 31, 2018, up from $137.5 million at December 31, 2017. The Company’s investment portfolio at December 31, 2018 consisted of $132.7 million in U.S. Government-sponsored agencies collateralized by residential mortgage obligations and $38.8 million in obligations of states and political subdivisions.

Cash and due from banks decreased by $40.8 million from $87.5 million at December 31, 2017 to $46.7 million at December 31, 2018.

Asset Quality

Nonperforming assets (which are comprised of nonperforming loans, other real estate owned (“OREO”) and repossessed vehicle holdings) at December 31, 2018 were $2.3 million, down from $4.4 million at December 31, 2017. Nonperforming assets as a percentage of total assets were 0.28% at December 31, 2018 and 0.59% at December 31, 2017. OREO totaled $1.2 million at December 31, 2018 and $1.3 million at December 31, 2017. Nonperforming loans at December 31, 2018 were $1.1 million, a decrease of $1.9 million from $3.0 million at December 31, 2017. Nonperforming loans as a percentage of total loans decreased to 0.20% at December 31, 2018, down from 0.62% at December 31, 2017.

During the year ended December 31, 2018 we recorded a provision for loan losses of $1 million, up $400 thousand from a provision of $600 thousand during the year ended December 31, 2017. Net charge-offs totaled $711 thousand during the twelve months ended December 31, 2018 and $480 thousand during the same period in 2017. Net charge-offs as a percentage of average loans were 0.14% during 2018 and 0.10% during the year ended December 31, 2017. The allowance for loan losses totaled $7.0 million at December 31, 2018 and $6.7 million at December 31, 2017. The allowance for loan losses as a percentage of total loans decreased from 1.37% at December 31, 2017 to 1.23% at December 31, 2018.

Shareholders’ Equity

Total shareholders’ equity increased by $11.2 million from $55.7 million at December 31, 2017 to $66.9 million at December 31, 2018. The largest component of the $11.2 million increase was earnings during the twelve-month period totaling $14.0 million. During 2018 the Company paid two 18 cents per share semi-annual cash dividends which had the effect of reducing shareholders’ equity by $1.8 million.

Net Interest Income and Net Interest Margin

Net interest income was $33.1 million for the year ended December 31, 2018, up $5.2 million, or 18%, from $27.9 million during 2017. Related to increases in average loan and investment balances and in the yield on these balances, interest income increased by $5.4 million, or 19%, from $28.9 million during 2017 to $34.3 million during the current year. Interest expense increased by $219 thousand.

Net interest income for the three months ended December 31, 2018 was $9.0 million, an increase of $1.6 million from the $7.4 million earned during the same period in 2017. Like the twelve-month comparison, the largest component of the increase in net interest income were increases in both rate and average balance of interest earning assets. Interest expense increased by $137 thousand from $262 thousand during the three months ended December 31, 2017 to $399 thousand during the quarter ended December 31, 2018. Interest expense related to the deposits housed in the Carson City branch totaled $81 thousand.

Net interest margin is net interest income expressed as a percentage of average interest-earning assets. Net interest margin for the year ended December 31, 2018 increased to 4.70%, up from 4.35% during 2017. Net interest margin for the three months ended December 31, 2018 increased to 4.73%, up from 4.28% during the fourth quarter of 2017. The increase in margin was mostly driven by increases in loan and investment yield. During the year ended December 31, 2018, the average yield on loans was 5.74% an increase of 27 basis points from 5.47% during 2017. During this same period the average yield on investments increased by 41 basis points from 2.17% to 2.58%. For the three months ended December 31, 2018 and 2017 loan yield was 5.78% and 5.53%, respectively. The average yield on investments was 2.66% during the three months ended December 31, 2018 and 2.21% during the quarter ended December 31, 2017.

Non-Interest Income/Expense

During the year ended December 31, 2018, non-interest income totaled $8.9 million, an increase of $601 thousand from the twelve months ended December 31, 2017. The largest component of this increase was a $209 thousand gain recorded upon the prospective adoption of a newly effective accounting pronouncement impacting the measurement of equity securities, which in our case consists of stock in our correspondent banks, without a readily determinable fair market value. Other significant increases included $109 thousand in service charges on deposit accounts, $187 thousand in interchange income and $69 thousand in loan service fees. We attribute these increases primarily to growth in the bank. Gains on sale of loans decreased by $136 thousand. The decline in gain on sale relates to a decline in the average premium received on sale.

During the three months ended December 31, 2018, non-interest income totaled $1.8 million, an increase of $174 thousand from the three months ended December 31, 2017. The largest component of this increase was a decrease of $141 thousand in loss on sale of investment securities. During the fourth quarter of 2017 the Company sold approximately $5.4 million of fixed income available-for-sale investment securities as part of its overall tax management planning, recording a $141 thousand loss on sale. The proceeds from these sales of securities were reinvested in higher-yielding investments.

During 2018, total non-interest expense increased by $1.7 million to $21.8 million. The three largest components of this increase were increases of $633 thousand in salaries and benefits, $313 thousand in professional fees and $352 thousand in other. The largest components of the increase in salary and benefit expense were increases of $762 thousand in salary expense and $386 thousand in bonus expense. Salary expense increased to $9.5 million related to additions to staff, merit and promotion increases and the implementation in 2018 of a $15 per hour minimum wage. Bonus expense is mostly a function of pretax income; the increase during the 2018 period is primarily related to the increase in pretax income and expansion in 2018 in the bonus plan to include nonofficer level personnel. These items were partially offset by an increase in the deferral of loan origination costs of $731 thousand to $2.5 million related mostly to an increase in loan origination activity.

During the three months ended December 31, 2018, total non-interest expense increased by $731 thousand to $5.7 million, up from $5.0 million for the comparable period in 2017. The largest component of this increase was an increase of $160 thousand in salaries and benefits. Salary expense increased by $264 thousand to $2.5 million and bonus expense increased by $100 thousand. These items were partially offset by an increase in deferred loan origination costs of $187 thousand.
