Income Taxes

Note 11 — Income Taxes

For each interim reporting period, we make an estimate of the effective tax rate we expect to be applicable for the full year for our operations. This estimated effective tax rate is used in providing for income taxes on a year-to-date basis. Our effective tax rate was as follows:

	Three Months Ended June 30,		Six Months Ended June 30,
	2021	2020	2021	2020
Effective tax rate	15.6%	5.7%	435.1%	15.7%

The fluctuation in the effective tax rate over the periods presented above was primarily attributable to a jurisdictional mix of income between periods. The effective tax rate differs from the U.S. federal statutory rate due primarily to benefits derived from stock-based compensation and the U.S. foreign derived intangible income deduction, tax credits available in the U.S., and income in foreign jurisdictions that are taxed at different rates than the U.S. statutory tax rate.

We are subject to taxation in the United States (federal, state, local) and foreign jurisdictions. As of June 30, 2021, tax years 2018 through 2021 are subject to examination by the tax authorities.

Pursuant to ASC 740, as of each balance sheet date, the Company assesses its uncertain tax positions to determine whether factors underlying the sustainability assertion have changed.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was signed into law. The CARES Act includes several significant business tax provisions that, among other things, eliminated the taxable income limit for certain net operating losses (“NOL”) and allow businesses and individuals to carry back NOLs arising in 2018, 2019, and 2020 to the five prior tax years; suspend the excess business loss rules under section 461(l); accelerate refunds of previously generated corporate AMT credits; generally loosen the business interest limitation under section 163(j) from 30 percent to 50 percent (special partnership rules apply); and fix the “retail glitch” for qualified improvement property in the 2017 tax code overhaul known informally as the Tax Cuts and Jobs Act (the “TCJA”) (TCJA, Public Law 115-97). ASC 740, Income Taxes, requires that the tax effects of changes in tax laws or rates be recorded discretely as a component of the income tax provision related to continuing operations in the period of enactment. We recorded any applicable impact from the CARES Act in the first quarter of 2020.
