Income Taxes
Income Taxes. For interim reporting periods, the Company prepares an estimate of the full-year income and the related income tax expense for each jurisdiction in which the Company operates. Changes in the geographical mix, permanent differences or estimated level of annual pretax income can impact the Company’s actual effective rate.
