Income Taxes

The effective tax rate was 5.0% and 16.3% for the three months ended March 31, 2020 and 2019, respectively. The decrease in the effective tax rate was due to lower pre-tax income during the three months ended March 31, 2020, reflective of increasing tax-exempt investments, and a provision in the CARES Act, which permitted the Company to recognize a benefit from net operating losses related to prior acquisitions of $1.0 million during the quarter ended March 31, 2020.
