Income Tax Disclosure [Abstract] |
Income Taxes | 10. Income Taxes The tax provision is based on the estimated annual effective tax rate for the year, which includes estimated federal, state and foreign income taxes (benefit) on the Company’s projected annual pre-tax income (loss) and estimated federal and state income taxes for certain noncontrolling interest subsidiaries that are not part of the Company’s consolidated income tax returns. The benefit for income taxes and the effective income tax rate for the three and nine months ended September 30, were as follows (in thousands):
|  | Three Months Ended September 30, |  |  | Nine Months Ended September 30, |
|  | 2014 |  |  | 2013 |  |  | 2014 |  |  | 2013 |
Benefit for income taxes |  | $ | (527 | ) |  | $ | (406 | ) |  | $ | (510 | ) |  | $ | (6,337 | )
Effective income tax rate |  |  | (12.6 | %) |  |  | (31.1 | %) |  |  | (3.5 | %) |  |  | (37.7 | %)
For the three and nine months ended September 30, 2014, no tax benefit could be recognized for the majority of the Company’s losses due to a full valuation allowance against all domestic deferred tax assets. The Company did recognize a tax benefit of approximately $552,000 as a discrete item in the third quarter of 2014 for the release of certain income tax reserves, due to the completion of an Internal Revenue Service examination of its 2010 and 2011 federal corporate income tax returns during the quarter (see below). For the three and nine months ended September 30, 2013, a net income tax benefit was recorded primarily due to an increase in net federal deferred tax assets not covered by a valuation allowance at that time. In addition, for the nine months ended September 30, 2013, additional net tax benefits were recorded for a potential net operating loss carryback for federal income tax purposes and the recognition of a benefit from the federal research tax credit for 2012 of $549,000, as a discrete item in the first quarter of 2013. The federal research tax credit for 2012 and 2013 was extended on January 2, 2013 pursuant to the American Taxpayer Relief Act of 2012. As of September 30, 2014, the Company has a valuation allowance of approximately $20,179,000 primarily against all domestic net deferred tax assets, for which realization cannot be considered more likely than not at this time. Management assesses the need for the valuation allowance on a quarterly basis. In assessing the need for a valuation allowance, the Company considers all positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and past financial performance. In 2013, the Company recorded an increase to the valuation allowance of approximately $10,241,000 for all remaining domestic net deferred tax assets not previously covered by a valuation allowance due to the following factors: (1) the Company’s forecast of future taxable income, of the appropriate nature, based on its quarterly assessment was not sufficient to support the recoverability of the remaining domestic deferred tax assets; (2) recent cumulative losses and the Company’s projection of continued losses into 2014; (3) while the Company has the ability to carryback federal net operating losses or credits to utilize against federal taxable income, it would generate only $1,600,000 in cash refunds; and (4) the lack of prudent and feasible tax planning strategies. These assessment factors remain unchanged, as does management’s conclusion concerning the need for a full valuation allowance against all domestic net deferred tax assets, as of September 30, 2014. The valuation allowance against these deferred tax assets may require adjustment in the future based on changes in the mix of temporary differences, changes in tax laws, and operating performance. If and when management determines the valuation allowance should be released, the adjustment would result in a tax benefit in the Condensed Consolidated Statements of Operations and may include a portion to be accounted for through “Additional paid-in capital”, a component of Stockholders’ Equity. The amount of the tax benefit to be recorded in a particular quarter could be material. In August 2013, the Company received notice from the Internal Revenue Service that its federal corporate tax returns for the tax years 2010 and 2011 had been selected for examination. The examination was completed resulting in a net refund due the Company of approximately $17,000, which was received and recorded as a discrete benefit in the third quarter of 2014. The Company’s subsidiary in Italy, Vicor Italy S.r.l. (“Vicor Italy”), recently underwent a tax inspection for tax years 2009 – 2013, covering corporation, regional and value added taxes. Vicor Italy received a preliminary tax audit report dated June 30, 2014. The Company filed a response to the preliminary tax audit report in the third quarter of 2014. While management believes it is too early to determine the likelihood or amount of potential liability at this time, it does not believe the ultimate impact of this matter will be material to the Company’s financial statements. There are no other income tax examinations or audits currently in process.
