Our tax loss and credit carryforwards at December 31, 2012 and 2013 relate to carryforwards in various U.S. state jurisdictions. At December 31, 2013, we had approximately $294,000 of state net operating loss carryforwards which will expire in 2023. At December 31, 2012 and 2013, we concluded that the benefit associated with a portion of our U.S. state net operating losses do not meet the more-likely-than-not recognition criteria, accordingly we have recognized a deferred income tax asset valuation allowance of $126,000 and $24,000 at December 31, 2012 and 2013, respectively, with respect to such carryforwards. Our provision for income taxes attributable to continuing operations includes an expense of $341,000 in 2011 and a benefit of $317,000 and $102,000 in 2012 and 2013, respectively, related to changes in such valuation allowance.

We file income tax returns in various U.S. federal, state and local jurisdictions. Prior to 2012, we also filed income tax returns in various foreign jurisdictions, principally in Canada and Taiwan. Our domestic income tax returns prior to 2010 are generally considered closed to examination by applicable tax authorities.
