Our state tax net operating losses of $0.9 million expire between December 31, 2014 and December 31, 2033. 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, 2013 and December 31, 2012, the amount of unrecognized tax benefits was $0.5 million and $0.8 million, respectively. Of these amounts, our income tax provision would decrease $0.5 million and $0.8 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, 2012 |  | $ | 756 |
Additions for tax positions taken in prior years |  |  | 27 |
Balance at December 31, 2012 |  | $ | 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 |
We are subject to income taxation in the U.S., numerous state jurisdictions, Mexico and Canada (beginning in late 2013). Because income tax return formats vary among the states, we file both unitary and separate company state income tax returns. In 2013, the IRS selected our 2011 and 2012 tax years for audit. Also in 2013, our 2009 through 2010 tax years and 2010 through 2012 tax years were selected for audit by Illinois and Massachusetts, respectively. In 2013, Texas audited refund claims that we submitted for tax years 2007 through 2009. We expect to receive approximately $0.3 million after our Texas claims are processed. Although no other significant examinations are currently in effect, tax years 2010 through 2012 generally remain open to examination by the major tax jurisdictions to which we are subject. It is reasonably possible that events could occur during the next twelve months which would change the amount of our unrecognized tax benefits. Our reserve could move up or down pending developments with lawsuits that have been initiated by unrelated taxpayers against several state revenue departments. We estimate it is reasonably possible that our reserve could either increase or decrease by $0.2 million depending upon the outcome of these events. We recognize interest expense and penalties related to income tax liabilities in our provision for income taxes. In our 2013 provision for income taxes we recognized approximately one thousand dollars of both net interest expense related to income tax liabilities and income tax penalties. On September 13, 2013, the Internal Revenue Service issued final regulations which affect all taxpayers that repair, acquire, or improve tangible property. These rules will be effective for our taxable year ending December 31, 2014. We do not anticipate that these regulations will have a material impact on our financial position or results of operations.
