7. Federal Income Taxes

The effective tax rate is the ratio of tax expense over pre-tax income (loss). The effective tax rate was 14% and 11% for the three and six months ended June 30, 2019, respectively, compared to 15% for each of the corresponding periods in 2018. The effective tax rate on pre-tax income was lower than the prevailing corporate federal income tax rate of 21%. Differences between the effective rates and the corporate federal income tax rate were primarily the result of the separate account dividends-received deduction, certain tax preferred investment income, foreign tax credits and other tax preference items. The six months ended June 30, 2019, effective tax rate is lower than the corresponding period in 2018 as a result of an increased level of realized losses and the associated tax benefit resulting from the application of the corporate federal income tax rate of 21%.
