[1] The sum of the earnings per share for the four quarters may differ from annual earnings per share due to the required method of computing the weighted average shares in interim periods.

[2] On December 22, 2017, the United States enacted tax reform legislation, the TCJ Act, resulting in significant modifications to existing law which resulted in a reduction in income tax expense for the year ended December 31, 2017. See Note 17: Income Taxes for additional information.

[3] Net income for years ended December 31, 2019, 2018, and 2017 was $215,695,961; $298,124,983 and $326,777,744, respectively.
