Income Taxes	12. Income Taxes We file federal and state income tax returns in the U.S. and income tax returns in foreign jurisdictions. With a few exceptions, we are no longer subject to income tax examinations by any of the taxing jurisdictions for years before 2009. We currently have no income tax examinations in process. As of June 30, 2015, we have provided a liability of approximately $28 thousand for unrecognized tax benefits related to various federal and state income tax positions, which would impact our effective tax rate if recognized. We accrue penalties and interest related to unrecognized tax benefits through income tax expense. We had approximately $3 thousand accrued for the payment of interest and penalties at June 30, 2015 compared to $2 thousand at December 31, 2014. Accrued interest and penalties are included in the $28 thousand of unrecognized tax benefits compared to $27 thousand at December 31, 2014. During the fiscal quarter ended June 30, 2015, we did not release any tax reserves associated with items falling outside the statute of limitations or the closure of certain tax years for examination purposes. Events could occur within the next 12 months that would have an impact on the amount of unrecognized tax benefits that would be required. Within the next 12 months, approximately $28 thousand of unrecognized tax benefits could be released related to items that are affected by expiring statutes of limitation. At June 30, 2015, due to cumulative losses and other factors, we continue to carry valuation allowances against the deferred assets primarily in the following foreign jurisdictions: United Kingdom, India, Luxembourg and Beijing, China. We have also established valuation allowances related to certain state deferred assets that we believe to be more likely than not to expire before they can be utilized. We evaluate the need for valuation allowances in each of our jurisdictions on a quarterly basis.
