Deferred income tax assets and liabilities are provided to reflect the future tax consequences of differences between the tax basis of assets and liabilities and their reported amounts in the financial statements.

For financial reporting purposes, income before income taxes includes the following components:

The components of the income tax provision (benefit) are as follows:

The reconciliation between the effective income tax rate and the U.S. federal statutory rate is as follows:

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income taxes. The temporary differences that give rise to significant portions of the deferred tax assets and liabilities as of December 31, 2011 and January 1, 2011 are presented below:

A valuation allowance to reduce the deferred tax assets reported is required if, based on the weight of the evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. For the fiscal years ended 2011 and 2010, management has determined that a valuation allowance is not required.

The Company intends and has the ability to indefinitely reinvest the earnings of its non-U.S. subsidiaries, which reflect full provision for non-U.S. income taxes, to expand its international operations. These earnings relate to ongoing operations and, at December 31, 2011, cumulative earnings were approximately $45 million. Accordingly, no provision has been made for U.S. income taxes that might be payable upon repatriation of such earnings. In the event any earnings of non-U.S. subsidiaries are repatriated, the Company will provide U.S. income taxes upon repatriation of such earnings, which will be offset by applicable foreign tax credits, subject to certain limitations.

The Company prescribes a recognition threshold and measurement attribute for an uncertain tax position taken or expected to be taken in a tax return.

The following is a roll-forward of the Company's unrecognized tax benefits:

At December 31, 2011, the Company had an unrecognized tax benefit of $609 including accrued interest. If recognized, the unrecognized tax benefit would have a favorable effect on the effective tax rate in future periods. The Company recognizes interest and penalties related to income tax matters in income tax expense. Interest related to the unrecognized tax benefit has been recognized and included in income tax expense. Interest accrued as of December 31, 2011, is not considered material to the Company's Consolidated Financial Statements.

The Company files U.S. federal income tax returns as well as income tax returns in various states and foreign jurisdictions. The Company is no longer subject to income tax examinations by tax authorities for years prior to 2004 for the majority of tax jurisdictions.

The Company's federal returns are currently under examination by the Internal Revenue Service (IRS) in the United States for the periods 2004 through 2009. The additional reserve during the current period in the table above is primarily related to an IRS proposal from Appeals regarding the Company's research and development tax credit position. To date, there have not been any other significant proposed adjustments that have not been accounted for in the Company's financial statements.

Audit outcomes and the timing of audit settlements are subject to significant uncertainty. It is reasonably possible that within the next twelve months the Company will resolve some or all of the matters presently under consideration for 2004 through 2009 with the IRS and that there could be significant increases or decreases to unrecognized tax benefits.
