Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes A reconciliation of the income tax expense (benefit) from continuing operations computed by applying the statutory federal income tax rate of 21% to income from continuing operations before income taxes to the income tax provision for the three months ended March 31, 2019 and for the three months ended April 1, 2018 was as follows (in millions):
| March 31, 2019 |  | April 1, 2018
Income tax expense at federal statutory rate | $ | 0.5 |  |  | $ | 0.5 |
State and foreign taxes, net of federal tax benefit and valuation allowance | 0.2 |  |  | 0.2 |
Release of valuation allowance due to FTT acquisition | (3.4 | ) |  | — |
GILTI | — |  |  | 0.1 |
Nondeductible expenses and other | 0.1 |  |  | 0.2 |
Impact of deferred tax liabilities for indefinite-lived assets | 0.1 |  |  | 0.4 |
Increase in reserves for uncertain tax positions | 1.6 |  |  | 0.2 |
Decrease in federal valuation allowance | (0.6 | ) |  | (0.7 | )
Total income tax (benefit) provision | $ | (1.5 | ) |  | $ | 0.9 |
In assessing the Company’s ability to realize deferred tax assets, management considers, on a periodic basis, whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. As such, management has determined that it is appropriate to maintain a full valuation allowance against the Company’s U.S. federal, combined state and certain foreign deferred tax assets, with the exception of an amount equal to its deferred tax liabilities, which can be expected to reverse over a definite life. Federal and state income tax laws impose restrictions on the utilization of NOLs and tax credit carryforwards in the event that an “ownership change” occurs for tax purposes, as defined by Section 382 of the Internal Revenue Code of 1986, as amended (“Section 382”). In general, an ownership change occurs when shareholders owning 5% or more of a “loss corporation” (a corporation entitled to use NOLs or other loss carryovers) have increased their ownership of stock in such corporation by more than 50 percentage points during any three-year period. The annual base Section 382 limitation is calculated by multiplying the loss corporation’s value at the time of the ownership change by the greater of the long-term tax-exempt rate determined by the Internal Revenue Service in the month of the ownership change or the two preceding months. This base limitation is subject to adjustments, including an increase for built-in gains recognized in the five-year period after the ownership change. In March 2010, an “ownership change” occurred that will limit the utilization of NOL carryforwards. In July 2011, another “ownership change” occurred. The March 2010 ownership change limitation is more restrictive. In prior years, the Company acquired corporations with NOL carryforwards at the date of acquisition (“Acquired NOLs”). The Acquired NOLs are subject to separate limitations that may further restrict the use of Acquired NOLs. As a result, the Company’s federal annual utilization of NOL carryforwards was limited to $27.0 million a year for the five years succeeding the March 2010 ownership change and $11.6 million for each year thereafter subject to separate limitations for Acquired NOLs. If the entire limitation amount is not utilized in a year, the excess can be carried forward and utilized in future years. For the three months ended March 31, 2019, there was no impact of such limitations on the income tax provision, since the amount of taxable income did not exceed the annual limitation amount. However, future equity offerings or acquisitions that have equity as a component of the purchase price could also cause an “ownership change.” If and when any other “ownership change” occurs, utilization of the NOLs or other tax attributes may be further limited. As discussed elsewhere, deferred tax assets relating to the NOL and credit carryforwards are offset by a full valuation allowance. In addition, utilization of state tax loss carryforwards is dependent upon sufficient taxable income apportioned to the states. The Company is subject to taxation in the U.S. and various state and foreign tax jurisdictions. The Company’s tax years for 2000 and later are subject to examination by the U.S. and state tax authorities due to the existence of the NOL carryforwards. Generally, the Company’s tax years for 2002 and later are subject to examination by various foreign tax authorities as well. During 2018 the Company was notified by the Internal Revenue Service that its federal income tax return for the calendar year ending December 27, 2015 had been selected for examination. The Company is currently in the process of responding to the information requested. As of December 30, 2018, the Company had $17.7 million of unrecognized tax benefits that, if recognized, would impact the Company’s effective income tax rate, subject to possible offset by an increase in the deferred tax asset valuation allowance. During the three months ended March 31, 2019, unrecognized tax benefits increased by $1.7 million relating to various current year positions. The Company recognizes interest and penalties related to unrecognized tax benefits in its provision for income taxes. For the three months ended March 31, 2019 and April 1, 2018, the Company recorded an expense for interest and penalties of $0.1 million. For the three months ended March 31, 2019 and April 1, 2018, there was no material benefit recorded related to the removal of interest and penalties. The Company believes that it is reasonably possible that as much as $0.4 million of the liabilities for uncertain tax positions will expire within twelve months of March 31, 2019 due to the expiration of various applicable statutes of limitations.
