|Income Tax Disclosure [Abstract]
Our effective tax rate was 46.7% and 23.7% for the three months ended March 31, 2020 and 2019, respectively. Income tax expense during interim periods is based on our estimated annual effective income tax rate plus any discrete items that are recorded in the period in which they occur. Our tax rate is affected by discrete items that may occur in any given year, but may not be consistent from year to year. The higher effective tax rate for the three months ended March 31, 2020 primarily results from a full valuation allowance established to offset the capital loss benefit in connection with our sale of Prime Turbines due to a lack of anticipated capital gain income in the carryforward period. We expect a lower effective tax rate for the year ended December 31, 2020 than the first quarter rate when the impact of the discrete item is spread over the entire twelve month period.
The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
