INCOME TAXES

NOTE 9.  INCOME TAXES

We record income taxes for interim periods based on an estimated annual effective tax rate.  The estimated annual effective tax rate is recomputed on a quarterly basis and may fluctuate due to changes in forecasted annual operating income, positive or negative changes to the valuation allowance for net deferred tax assets, and changes to actual or forecasted permanent book to tax differences. 

Our effective tax rates were (0.3)% and 5.0% for the three months ended September 30, 2020 and 2019, respectively, and (3.6)% and (67.0)% for the nine months ended September 30, 2020 and 2019, respectively. The changes in our effective tax rates and the primary reasons that these effective tax rates differ from the applicable federal statutory rates are the fluctuations in earnings among the various jurisdictions in which we operate, increases in valuation allowances and foreign tax rate differentials.

The CARES Act, among other things, permits net operating loss (“NOL”) carryovers and carrybacks to offset 100% of taxable income for taxable years beginning before 2021.  In addition, the CARES Act allows NOLs incurred in 2018, 2019 and 2020 to be carried back to each of the five preceding years to generate a refund for previously paid income taxes.  The CARES Act also contains modifications on the limitation of business interest for tax years beginning in 2019 and 2020.  These modifications increase the allowable business interest deduction from 30% of adjusted taxable income to 50% of adjusted taxable income.  Based upon current facts and circumstances, we do not expect that these provisions would result in a material cash benefit or impact to the effective tax rate.
