12. Income Taxes

 

Our effective income tax rate fluctuates from the U.S. statutory tax rate based on, among other factors, changes in pretax income in jurisdictions with varying statutory tax rates, the impact of U.S. state and local taxes, the realizability of deferred tax assets and other differences related to the recognition of income and expense between U.S. GAAP and tax accounting. 

 

Our effective income tax rate for the three months ended March 31, 2021 was 16.5%, compared with 13.9% for the three months ended March 31, 2020.  The higher effective income tax rate for the three months ended March 31, 2021 was primarily attributable to non-deductible component of the goodwill impairment recorded in the first quarter of 2020. This was partially offset by the valuation allowance included in the 2021 estimated annual effective tax rate. 

 

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized, and when necessary valuation allowances are provided. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. We assess the realizability of our deferred tax assets quarterly and consider carryback availability, the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. In the first quarter of 2021, the effective tax rate takes into consideration the estimated valuation allowance based on forecasted 2021 income. 

We continue to monitor income tax developments in the United States and other countries where we have legal entities. During the first quarter of 2021, the United States enacted the American Rescue Plan of 2021, which contains various tax provisions. As a result of this legislation, we have considered these tax provisions and do not expect any material impacts to our financial statements. We will incorporate into our future financial statements the impacts, if any, of future regulations and additional authoritative guidance when finalized.
