Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes During the year ended December 31, 2015, the Company restructured its legal entities such that there will be only one U.S. tax filing group filing a single U.S. consolidated federal income tax return beginning in 2016. Prior to 2016, the Company’s corporate organizational structure required the filing of two separate consolidated U.S. Federal income tax returns. Taxable income of one group could not be offset by tax attributes, including net operating losses, of the other group. A reconciliation of the U.S. federal statutory tax rate to the Company’s effective income tax rate is as follows:
| Three months ended March 31,
| 2016 |  | 2015
U.S. federal statutory tax rate | (35.0 | )% |  | (35.0 | )%
State income taxes, net of federal benefit | (1.2 | ) |  | (5.4 | )
Non-U.S. income taxed at different rates | 0.3 |  |  | 23.6 |
Non-deductible expenses | — |  |  | (5.4 | )
Domestic production activities deduction | — |  |  | 1.1 |
Other | 0.6 |  |  | — |
Effective income tax rate | (35.3 | )% |  | (21.1 | )%
Fluctuations in effective tax rates have historically been impacted by permanent tax differences with no associated income tax impact, changes in state apportionment factors, including the effect on state deferred tax assets and liabilities, and benefits of non-U.S. income taxed at lower rates. Changes in the effective tax rate during the three months ended March 31, 2016 included the Company not qualifying for the domestic production activities deduction. Deferred taxes are presented in the balance sheets as follows (in thousands):
|  | March 31, 2016 |  | December 31, 2015
Current deferred tax assets |  | $ | 4,139 |  |  | $ | 2,649 |
Non-current deferred tax assets |  | 3 |  |  | 17,229 |
Non-current deferred tax liabilities |  | (1,755 | ) |  | (23,823 | )
Net deferred tax assets (liabilities) |  | $ | 2,387 |  |  | $ | (3,945 | )
