INCOME TAXES |
INCOME TAXES | 19. INCOME TAXES The Company records income tax expense during interim periods based on the best estimate of the full year’s tax rate as adjusted for discrete items, if any, that are taken into account in the relevant interim period. Each quarter, the Company updates its estimate of the annual effective tax rate and any change in the estimated rate is recorded on a cumulative basis. The effective tax rate from continuing operations was 30.7% and 32.7% for the three months ended September 30, 2021 and 2020, respectively, and 33.5% and 29.1% for the nine months ended September 30, 2021 and 2020, respectively. The lower effective tax rate in the third quarter of 2021 is primarily due to the enactment of a UK tax rate increase in the third quarter of 2020 which triggered the remeasurement of UK deferred tax liabilities. The higher effective tax rate through the third quarter of 2021 is primarily due to the remeasurement of UK deferred tax liabilities following the UK tax rate increase enacted during the second quarter of 2021 and effective April 1, 2023. The Company petitioned the U.S. Tax Court on January 13, 2017, May 7, 2018 and November 29, 2018 for a redetermination of IRS notices of deficiency for Cboe and certain of its subsidiaries for tax years 2011 through 2015 related to its Section 199 claims. These petitions resulted in the establishment of three cases before the U.S. Tax Court. The Company also filed a complaint on October 5, 2018 with the Court of Federal Claims for a refund of Section 199 claims related to tax years 2008 through 2010. The complaint resulted in the establishment of a single case before the Court of Federal Claims. The first case that went to trial involved certain subsidiaries related to electronic trading for tax years 2011, 2012 and 2013. The U.S. Tax Court held the trial remotely from May 24, 2021 to June 1, 2021. Post-trial briefing in that case concluded on October 28, 2021. On July 9, 2021, the Company sought a stay in the second U.S. Tax Court case involving certain subsidiaries related to hybrid trading for the same tax years, which was denied on August 8, 2021. As a result, two cases remain pending in U.S. Tax Court, as does the case pending before the Court of Federal Claims. Trial dates in those cases have not been established. Although there can be no assurances, the Company continues to believe, based on its current assessment of the Section 199 claims, that the reasonably expected aggregate amount of any additional liabilities that may result from these cases, if any, will not have a material adverse effect on the financial position, results of operations, or cash flows of the Company. As of September 30, 2021, the Company has not resolved these matters, and proceedings continue in U.S. Tax Court and the Court of Federal Claims.
