return on average assets in 2019, as compared to the previous year, was primarily due to average asset growth outpacing the increase in net income. Average assets increased in 2019 by $107.6 million, or 12.0%, as the Company grew its total assets from $933.1 million at December 31, 2018 to $1.1 billion at December 31, 2019. The decrease in return on average equity in 2019, as compared to the previous year, was primarily due to the growth in equity outpacing the increase in net income due to the completion of the Private Placement.
Net interest income, before provision for loan losses, increased $2.5 million, or 9.6%, to $28.2 million in 2019 on average interest earning assets of $948.0 million as compared to net interest income before provision for loan losses of $25.8 million in 2018 on average interest earning assets of $852.1 million. Interest and dividend income increased $6.9 million in 2019 to $41.8 million, as compared to interest and dividend income of $34.8 million in 2018. The aggregate increase in the average balance of interest-earning assets of $95.9 million was further enhanced by an increase of 31 basis points in the overall average yield earned on those assets that contributed an increase in interest and dividend income in 2019, as compared to the previous year. The $6.9 million increase in interest income was partially offset by an increase in interest expense of $4.5 million due to an increase in average interest-bearing liabilities of $80.1 million and an increase in the average rate paid on those liabilities of 43 basis points in 2019 as compared to 2018.
The Company recorded a provision for loan losses of $2.0 million in 2019 as compared to $1.5 million in the prior year. The $469,000 year-over-year increase in provision for loan losses reflected continued significant growth in the Bank’s commercial and consumer lending portfolios, as well as changes to both quantitative and environmental factors deemed appropriate for the Bank’s loan portfolio. Net loan balances increased 26.0% from December 31, 2018 to December 31, 2019. The Company recorded $603,000 in net charge-offs in 2019 as compared to $1.3 million in net charge-offs in 2018. The ratio of net charge-offs to average loans decreased to 0.09% in 2019 from 0.22% in 2018. The decrease in the year-over-year charge-off rate was due primarily to the charge-off in 2018 of a single fully-reserved commercial real estate loan in the amount of $596,000 and the charge-off of a single fully-reserved commercial and industrial loan in the amount of $124,000.
Noninterest income was $4.9 million in 2019, an increase of $1.1 million, or 28.2%, from $3.8 million in 2018. Net gains on the sales and redemptions of investment securities increased $511,000 from a loss of $182,000 in 2018 to a gain of $329,000 in 2019. During 2019, investment securities sales were part of the Company’s portfolio optimization and liquidity management strategies. During 2018, the Company realized losses of $182,000 on the sales of certain securities in order to provide funding for reinvestment into loans and securities considered to be better matches for the Company’s overall balance sheet strategies. All other categories of noninterest income increased $571,000 in aggregate during 2019, as compared to the previous year. The increase was primarily due to increases in service charges on deposits accounts, gains on marketable equity securities, debit card interchange fees, loan servicing fees, and earnings and gain on bank owned life of $243,000, $143,000, $81,000, $41,000, and $35,000, respectively.
Noninterest expense increased $2.2 million, or 9.3%, to $25.7 million in 2019 from $23.5 million in 2018. The year-over-year increase in noninterest expense was primarily due to personnel expenses that increased $956,000, or 7.5%, in 2019 as compared to 2018. Noninterest expense further increased due to increases in building and occupancy costs, data processing costs, and foreclosed real estate expenses of $431,000, $415,000, and $187,000, respectively. All other noninterest expenses increased $192,000, or 2.9%, in 2019, as compared to the previous year. Substantially all categories of noninterest expense, not related to personnel costs, increased in a manner that was proportional to the Company’s increases in total asset size and reflected the deployment of additional resources by the Company into risk management systems and improved customer service activities.
Total assets were $1.1 billion at December 31, 2019 as compared to $933.1 million at December 31, 2018. The increase in total assets of $160.7 million, or 17.2%, was the result of the increase in loans, principally consumer and commercial loans, of $161.2 million, partially offset by a $6.2 million decrease in cash and cash equivalents. All other assets increased by a net $5.7 million, primarily due to an increase in the operating lease right-of-use asset, premises and equipment, and investment securities of $2.4 million, $2.1 million and
