Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesOur overall effective income tax rates were 26.8% and 26.7% for the three and six months ended June 30, 2022 and 24.9% and 24.2% for the three and six months ended June 30, 2021. The rates for the three and six months ended June 30, 2022 resulted in income tax expense of $69.4 million and $122.9 million, respectively, compared to income tax expense of $51.2 million and $84.8 million for the three and six months ended June 30, 2021, respectively. The year-over-year increase in the effective tax rate for the three and six months ended June 30, 2022, was primarily due to energy tax credits not being extended into 2022 and a decrease in the windfall on non-qualifying stock options exercised and lapsed restricted stock during the respective periods.
