Income Tax Disclosure [Abstract]  
Income Tax Disclosure [Text Block] Income TaxesThe Company recorded an effective tax rate of 25.4 percent and 20.8 percent for the three months ended March 31, 2022 and 2021, respectively. The effective tax rate for the three months ended March 31, 2022 differed from the statutory Federal income tax rate of 21.0 percent primarily due to state income taxes and the impact of permanent tax differences of which none are individually significant. While the Company expects its effective tax rate to be fairly consistent in the near term, it will vary depending on recurring items such as the amount of income earned in each state and the state tax rate applicable to such income. Discrete items during interim periods may also affect the Company's tax rates.
