During the nine months ended September 30, 2017 and 2016 we recorded a provision for loan losses of $600 thousand. Net charge-offs totaled $327 thousand and $201 thousand during the nine months ended September 30, 2017 and 2016, respectively. The allowance for loan losses totaled $6.8 million at September 30, 2017 and $6.5 million at September 30, 2016. The allowance for loan losses as a percentage of total loans decreased slightly from 1.45% at September 30, 2016 to 1.42% at September 30, 2017.

Shareholders’ Equity

Total shareholders’ equity increased by $7.3 million from $48.3 million at September 30, 2016 to $55.6 million at September 30, 2017. The $7.3 million includes earnings during the twelve month period totaling $9.2 million and stock option activity totaling $0.5 million. These items were partially offset by a decrease in net unrealized gains on investment securities of $1.2 million, a $0.10 per share cash dividend, paid in November 2016 and a $0.14 per share cash dividend paid in May 2017. The two cash dividends totaled $1.2 million.

In May, 2017 the Company’s outstanding warrant, which represented the right to purchase 150,000 shares of common stock at $5.25 per share, was exercised in a cashless exercise resulting in the issuance of 108,111 common shares.

Net Interest Income and Net Interest Margin

Net interest income, on a nontax-equivalent basis, was $7.1 million for the three months ended September 30, 2017, an increase of $1.0 million, or 17%, from $6.1 million for the same period in 2016. The increase in net interest income includes an increase of $1 million in interest income; the largest component of which was an increase in interest and fees on loans of $710 thousand. This increase in interest and fees on loans was related to an increase in average loan balances of $36 million and an increase in yield on loans of 17 basis points from 5.32% during the 2016 quarter to 5.49% during the current quarter. We attribute this increase in yield primarily to an increase in the prime interest rate as well as a decrease in net loan costs of $47 thousand. Interest expense declined by $1 thousand related to the payoff of Plumas Bancorp’s note payable during the second quarter of 2017 mostly offset by an increase in the average balance of interest-bearing deposits and an increase in the rate paid on Plumas Bancorp’s junior subordinated debentures. Interest on the note payable was $31 thousand during the third quarter of 2016. Net interest margin for the three months ended September 30, 2017 increased 11 basis points to 4.31%, up from 4.20% for the same period in 2016.

Net interest income, on a nontax-equivalent basis, for the nine months ended September 30, 2017 was $20.5 million, an increase of $2.8 million from the $17.7 million earned during the same period in 2016. Driven primarily by an increase in average loan balances, interest income increased by $2.8 million while interest expense, which benefited from the payoff of the Bancorp’s note payable, declined by $7 thousand. Net interest margin for the nine months ended September 30, 2017 increased 15 basis points to 4.37%, up from 4.22% for the same period in 2016.

Non-Interest Income/Expense

During the three months ended September 30, 2017, non-interest income totaled $2.2 million, an increase of $190 thousand from the three months ended September 30, 2016. The largest component of this increase was a $111 thousand increase in service charge income primarily related to an increase in interchange income on debit card transactions, an increase in overdraft income and an increase in service charges on deposit accounts. In addition, gains on sale of SBA loans increased by $52 thousand from $505 thousand during the three months ended September 30, 2016 to $557 thousand during the current quarter.

During the nine months ended September 30, 2017, non-interest income totaled $6.6 million, an increase of $912 thousand from the nine months ended September 30, 2016. The largest component of this increase was a $473 thousand increase in gains on sale of SBA loans from $1.4 million during the nine months ended September 30, 2016 to $1.9 million during the current period. Proceeds from SBA loan sales totaled $31.4 million during the current period and $23.7 million during the nine months ended September 30, 2016. Loans originated for sale totaled $27.2 million during the nine months ended September 30, 2017 and $22.2 million during the nine months ended September 30, 2016. In addition, service charge income increased by $319 thousand during the comparison period mostly related to an increase in interchange income on debit card transactions, an increase in overdraft income and an increase in service charges on deposit accounts.

During the three months ended September 30, 2017, total non-interest expense increased by $423 thousand, or 9%, to $5.1 million, up from $4.7 million for the comparable period in 2016. The two largest components of this increase were increases of $275 thousand in salary and benefit expense and $97 thousand in the provision for changes in OREO valuation. Salary expense increased by $99 thousand to $2.2 million related to additions to staff and merit and promotion increases. Commission expense related to our SBA operations increased by $56 thousand consistent with the increase in SBA activity and bonus expense increased by $50 thousand related to increased profitability. The increase in the provision for changes in OREO valuation was related to a $95 thousand write-down, based on a recent appraisal, on the Company’s largest OREO property.

During the nine months ended September 30, 2017, total non-interest expense increased by $1.1 million to $15.1 million mostly related to a $900 thousand increase in salary and benefit expense. The three largest components of the increase in salary and benefit expense were increases of $355 thousand in salary expense, $189 thousand in accrued bonus expense and $163 thousand in commissions.
