Income Taxes INCOME TAXES
    At March 31, 2021 and December 31, 2020, the Company had approximately $237.4 million and $227.9 million, respectively, of gross unrecognized income tax benefits, all of which would affect the Company’s effective tax rate if recognized. Gross unrecognized income tax benefits as of March 31, 2021 and December 31, 2020 exclude certain indirect favorable effects that relate to other tax jurisdictions of approximately $68.5 million and $64.1 million, respectively. At March 31, 2021 and December 31, 2020, the Company had approximately $55.2 million and $57.1 million, respectively, of accrued or deferred taxes related to uncertain income tax positions connected with ongoing income tax audits in various jurisdictions that it expects to settle or pay in the next 12 months. The Company accrues interest and penalties related to unrecognized tax benefits in its provision for income taxes. At March 31, 2021 and December 31, 2020, the Company had accrued interest and penalties related to unrecognized tax benefits of approximately $39.6 million and $39.4 million, respectively. Generally, tax years 2015 through 2020 remain open to examination by taxing authorities in the United States and certain other foreign tax jurisdictions. The Company and its subsidiaries are routinely examined by tax authorities in the United States and in various state, local and foreign jurisdictions. As of March 31, 2021, a number of income tax examinations in foreign jurisdictions are ongoing.

    The Company maintains a valuation allowance to fully reserve against its net deferred tax assets in the United States, Brazil and certain other foreign jurisdictions. A valuation allowance is established when it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company regularly assesses the likelihood that its deferred tax assets will be recovered from estimated future taxable income and available tax planning strategies and has determined that all adjustments to the valuation allowances have been appropriate. In making this assessment, all available evidence was considered including the current economic climate, as well as reasonable tax planning strategies. The Company believes it is more likely than not that the Company will realize its remaining net deferred tax assets, net of the valuation allowance, in future years.
