Income Taxes [Abstract]
Income Taxes	4. INCOME TAXES Our total provision for income taxes was $35.3 million and $16.2 million for the three months ended March 31, 2022 and 2021, respectively. We record our income tax provision using a full-year forecasted methodology, including discrete items in the period in which they occur. Our year-to-date effective tax rate for the three months ended March 31, 2022 was 25.6%, compared to 25.5% for the three months ended March 31, 2021. Our federal income tax returns for the tax years 2018 and forward are available for examination by the U.S. Internal Revenue Service (“IRS”).  The statute of limitations for the 2018 federal return will expire on October 15, 2022, unless extended by consent. Our state income tax returns for 2017 through 2021 remain subject to examination by various state authorities with the latest period closing on December 31, 2026.  We have not extended the statutes of limitations in any state jurisdictions with respect to years prior to 2017.
