Income Tax Disclosure [Abstract]
Income Taxes	Note 10: Income Taxes Management estimates the annual effective income tax rate quarterly, based on current annual forecasted results. Items unrelated to current year ordinary income are recognized entirely in the period identified as a discrete item of tax. The quarterly income tax provision includes tax on ordinary income provided at the most recent estimated annual effective tax rate (“ETR”), increased or decreased for the tax effect of discrete items. For the six months ended June 30, 2020 and 2019, our estimated annual effective tax rates applied to ordinary income were 24.7% and 16.0%, respectively. The difference between the federal statutory rate of 21.0% and the projected annual ETR of 24.7% for 2020 is primarily due to research and development credits. Discrete items during the six months ended June 30, 2020 and 2019 were not significant, and our ETR for the first half of each year was 23.6% and 16.0%, respectively.
