higher cost money market and savings deposits. Average loans for the six months increased $92.6 million, or 19.1%, to $576.7 million when compared to the six months ended 2019 with growth concentrated in our commercial attorney and commercial real estate portfolios.
The provision for loan losses was $3.8 million for the six months ended 2020, a $3.0 million increase from the comparable period in 2019. The higher provision was due to an increase in our economic and non-economic qualitative risk factors associated with the COVID-19 pandemic, although the ultimate impact of the crisis is unknown and highly uncertain at this time.
Noninterest income increased $904 thousand, or 17.5%, to $6.1 million for the six months ended 2020 as compared to the same period in 2019. Our merchant services platform experienced strong growth that was partially offset by decreased income on ASP fees for off-balance sheet funds. Merchant processing income increased $1.1 million, or 23.3%, compared to the six months ended 2019. This increase was due to the expansion of our sales channels through independent sales organizations (“ISOs”), merchants and fee allocation arrangements as we continue to focus on prudently growing this source of stable fee income. Other noninterest income, consisting primarily of ASP fee income, declined by $193 thousand compared to the same period in 2019 due to significant reductions in short-term interest rates. Our ASP fee income is impacted by the volume and duration of off-balance sheet funds and short-term interest rates.
Noninterest expense increased $1.7 million, or 13.8%, to $13.6 million for the six months ended 2020 as compared to the same period in 2019. This increase was primarily driven by increases in employee compensation and benefits, data processing and occupancy and equipment costs. Employee compensation and benefits costs increased $1.1 million, or 15.0%, due to increases in the number of employees, as well as the impact of year-end salary and stock-based compensation increases. Data processing costs increased $281 thousand, or 23.1%, as processing volumes increased and additional costs were incurred related to certain system implementations. Occupancy and equipment costs increased $237 thousand, or 26.9%, primarily due to amortization of internally developed software for our technology initiatives, precautionary office cleaning costs related to COVID-19 and additional office space to support growth. The Company’s efficiency ratio was 55.9% for the six months ended June 30, 2020 as compared to 55.3% for the same period ended 2019 as we continue to strategically invest in our Company’s future.
The effective tax rate for the six months ended 2020 was approximately 26.5% as compared to approximately 27.3% for same period in 2019.
Asset Quality
Nonperforming assets, consisting of several nonaccrual consumer loans, totaled $1.3 million as of June 30, 2020. Nonperforming assets as a percentage of total assets was 0.16%. There were no nonperforming assets as of June 30, 2019. The allowance for loan losses was $10.7 million, or 1.80% of total loans, as compared to $6.4 million, or 1.25% of total loans as of June 30, 2019. The increase in the allowance as a percentage of loans was related to increases in economic and non-economic qualitative risk factors associated with the COVID-19 pandemic, as well as loan growth in the commercial, commercial real estate and consumer loan categories. The ultimate impact of the crisis is unknown and highly uncertain at this time.
Balance Sheet
At June 30, 2020, total assets were $851.9 million, reflecting a $119.4 million, or 16.3% increase from June 30, 2019. This increase is attributable to increases in loans totaling $79.1 million, or 15.4%, to $593.7 million, primarily driven by commercial attorney, commercial real estate and consumer loans, funded with core low-cost deposits.
Total deposits were $724.9 million as of June 30, 2020, a $101.8 million, or 16.3% increase from June 30, 2019. This was primarily due to a $60.4 million, or 16.4% increase in Savings, NOW and Money Market deposits to $429.2 million, a $41.8 million, or 17.8%, increase in noninterest bearing demand deposits to $276.3 million. The net increase in deposits was primarily driven by commercial and escrow low-cost deposits from our litigation and small business platforms.
Stockholders’ equity increased $15.9 million to $118.2 million at June 30, 2020 compared to June 30, 2019. In the first six months of 2020, 34,306 shares of treasury stock were repurchased at a cost of $567 thousand under the Company’s previously announced stock repurchase program, authorizing the repurchase of up to 300,000 shares of our common stock.
