INCOME TAX [Abstract]

INCOME TAX

3.  INCOME TAX

Our effective tax rate for the three months ended June 30, 2022 and 2021 was (23.2%) and 22.5%, respectively.  Our effective tax rate for the six months ended June 30, 2022 and 2021 was 26.3% and 22.8%, respectively.  Our effective tax rate differs from the federal statutory rate primarily due to U.S. state income tax expense, expenses that are nondeductible for tax purposes, the change in our valuation allowance associated with our deferred tax assets, and differences in tax rates in foreign jurisdictions.
