Income Taxes

The Company has provided income taxes for the three and six month periods ended July 2, 2016 and July 4, 2015, based on its estimate of the effective tax rate for the entire 2016 and 2015 fiscal years. The Company’s estimated annual effective tax rate is based on forecasts of income by jurisdiction, permanent differences between book and tax income, including Subpart F income and biofuel tax incentives, the relative proportion of income and losses by jurisdiction, and statutory income tax rates. Discrete events such as the assessment of the ultimate outcome of tax audits, audit settlements, recognizing previously unrecognized tax benefits due to the lapsing of statutes of limitation, recognizing or derecognizing deferred tax assets due to projections of income or loss and changes in tax laws are recognized in the period in which they occur.

Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company expects to indefinitely reinvest the earnings of its foreign subsidiaries outside of the United States and has generally not provided deferred income taxes on the accumulated earnings of its foreign subsidiaries.

The Company periodically assesses whether it is more likely than not that it will generate sufficient taxable income to realize its deferred income tax assets. In making this determination, the Company considers all available positive and negative evidence and makes certain assumptions. The Company considers, among other things, its deferred tax liabilities, the overall business environment, its historical earnings and losses, current industry trends and its outlook for future years. Certain VION Companies acquired as part of the VION Acquisition have deferred tax assets for tax loss carryforwards, and the Company has recorded valuation allowances in respect to those losses to the extent it has been determined that it is not more likely than not that the deferred tax assets will be realized.

Unrecognized tax benefits represent the difference between tax positions taken or expected to be taken in a tax return and the benefits recognized for financial statement purposes.
