We are subject to income taxation in the U.S., numerous state jurisdictions, Mexico and Canada. Because income tax return formats vary among the states, we file both unitary and separate company state income tax returns. Our state tax net operating losses of $1.4 million expire between December 31, 2015 and December 31, 2034. Management believes it is more likely than not that the deferred tax assets will be realized with the exception of $0.1 million related to state tax net operating losses for which a valuation allowance has been established. As of December 31, 2014 and December 31, 2013, the amount of unrecognized tax benefits was $1.1 million and $0.5 million, respectively. Of these amounts, our income tax provision would decrease $0.7 million and $0.3 million respectively, if recognized. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):
Balance at January 1, 2013 | $ | 783 |
Additions for tax positions taken in prior years |  | 17 |
Reductions for tax positions taken in prior years |  | (184 | )
Reductions as a result of a lapse of the applicable statute of limitations |  | (157 | )
Balance at December 31, 2013 | $ | 459 |
Additions for tax positions taken in prior years |  | 231 |
Additions for tax positions related to the current year |  | 587 |
Reductions as a result of a lapse of the applicable statute of limitations |  | (212 | )
Balance at December 31, 2014 | $ | 1,065 |
We estimate it is reasonably possible that our reserve could either increase or decrease by $0.3 million during the next twelve months. We recognize interest expense and penalties related to income tax liabilities in our provision for income taxes. In our 2014 provision for income taxes we recognized approximately one thousand dollars of net interest expense related to income tax liabilities and income tax penalties. In 2014, the IRS closed their examination of our 2011 and 2012 tax years with no changes. Also in 2014, Illinois closed audits of our 2009 through 2011 tax years, Massachusetts closed audits of our 2010 through 2012 tax years and Texas closed audits of refund claims that we submitted for tax years 2007 through 2009. We received $0.3 million net after offsetting small settlement payments against the refunds. Although no other material examinations are currently in effect, tax years 2011 through 2013 generally remain open to examination by the major tax jurisdictions to which we are subject.
