Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes The following table presents the provision for income taxes from continuing operations and the effective tax rates for the periods indicated (in thousands, except percentages):
|  | Three Months Ended
|  | March 31, 2018 |  | April 1, 2017
Provision for income taxes |  | $ | 110 |  |  | $ | 673 |
Effective tax rate |  | (0.9 | )% |  | (2.1 | )%
The income tax provision for the three months ended March 31, 2018 and April 1, 2017 consisted primarily of foreign and state income taxes. The effective tax rate for the three months ended March 31, 2018 and April 1, 2017 was determined using an estimated annual effective tax rate adjusted for discrete items, if any, that occurred during the respective periods. The Company’s effective tax rate for the three months ended March 31, 2018 and April 1, 2017 is impacted by the change in foreign income tax expense. Deferred tax assets are recognized if realization of such assets is more likely than not. The Company has established and continues to maintain a full valuation allowance against its net deferred tax assets, with the exception of certain foreign deferred tax assets, as the Company does not believe that realization of those assets is more likely than not. The Company’s effective tax rate may be subject to fluctuation during the year as new information is obtained, which may affect the assumptions used to estimate the annual effective tax rate, including factors such as the mix of forecasted pre-tax earnings in the various jurisdictions in which it operates, valuation allowances against deferred tax assets, the recognition or de-recognition of tax benefits related to uncertain tax positions, and changes in or the interpretation of tax laws in jurisdictions where it conducts business.
