Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesOur overall effective income tax rates were 17.3% and 21.5% for the three and six months ended June 30, 2023 and 26.8% and 26.7% for the three and six months ended June 30, 2022. The rates for the three and six months ended June 30, 2023 resulted in income tax expense of $19.6 million and $47.8 million, respectively, compared to the income tax expense of $69.4 million and $122.9 million for the three and six months ended June 30, 2022, respectively. The year-over-year decrease in the effective tax rate for the three and six months ended June 30, 2023, was primarily due to energy tax credits used in 2023 that had not been extended into 2022 by June 30, 2022, and an increase in the windfall on non-qualifying stock options exercised and lapsed restricted stock during the periods.
