Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes The following table compares our income tax expense (benefit) and effective tax rates for the three months ended June 30, 2019 and 2018:
| Three months ended
| June 30,
(Dollars in thousands) | 2019 |  | 2018
Income tax expense (benefit) | $ | 25 |  |  | $ | (49 | )
Effective tax rate | (1.6 | )% |  | 2.7 | %
For the three months ended June 30, 2019 and 2018, the effective tax rate was different than the statutory rate due primarily to the recognition of net operating losses as deferred tax assets, which were offset by increases in the valuation allowance, certain foreign and state tax effects and other U.S. permanent book to tax differences. We have recorded a valuation allowance offsetting substantially all of our deferred tax assets. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the periods in which those temporary differences are deductible. Because of our losses in prior periods, management believes that it is more-likely-than-not that we will not realize the benefits of these deductible differences.
