The Company's deferred tax asset valuation allowances are primarily the result of uncertainties regarding the future realization of recorded tax benefits on tax loss carryforwards for certain entities. The Company's assumptions, judgments and estimates relative to the valuation of these net deferred tax assets take into account available positive and negative evidence of realizability, including recent financial performance, the ability to realize benefits of restructuring and other recent actions, projections of the amount and category of future taxable income and tax planning strategies. Actual future operating results and the underlying amount and category of income in future periods could differ from the Company's current assumptions, judgments and estimates.

All unrecognized tax positions would impact the Company's effective tax rate if recognized. The Company’s policy with respect to penalties and interest in connection with income tax assessments or related to unrecognized tax benefits is to classify penalties as provision for income taxes and interest as interest expense in its consolidated statement of income. There were no material income tax penalties or interest accrued during the three or six months endedJune 30, 2013 or 2012.

The Company files income tax returns in the U.S. Federal and several state jurisdictions as well as in many foreign jurisdictions. With certain exceptions, the Company is no longer subject to U.S. Federal, state and local, or foreign income tax examinations for years before 2009.
