As of December 31, 2013, the Company had approximately $13 million of state net operating loss carryforwards which expire on various dates between 2018 and 2031. The Company also had state tax carryforwards of $889,000, which begin to expire in 2014. The Company considers the earnings of the Mexican subsidiary to be indefinitely reinvested outside the United States on the basis of estimates that future domestic cash generation will be sufficient to meet future domestic cash needs. Should the Company decide to repatriate the foreign earnings, the income tax provision would be adjusted in the period it is determined that the earnings will no longer be indefinitely reinvested outside the United States, and a deferred tax liability of approximately $650,000 related to the United States federal and state income taxes and foreign withholding taxes on approximately $1.9 million of undistributed foreign earnings would be recorded. The Company files income tax returns in the United States Federal jurisdiction, in a limited number of foreign jurisdictions, and in many state jurisdictions. The Company is currently under examination by the Internal Revenue Service for years 2009, 2010 and 2011. With few exceptions, the Company is no longer subject to United States Federal or state income tax examinations for years before 2009. A summary of the changes in the unrecognized tax benefits during the years ended December 31, 2013, 2012 and 2011 is presented below (in thousands):
|  | 2013 |  |  | 2012 |  |  | 2011 |
Unrecognized tax benefits, beginning of year |  | $ | 5,245 |  |  | $ | 309 |  |  | $ | 125 |
Increases for positions taken in prior years |  |  | 646 |  |  |  | 3,571 |  |  |  | 10 |
Decreases for positions taken in prior years |  |  | (696 | ) |  |  | (184 | ) |  |  | — |
Increases for positions taken in the current year |  |  | 1,012 |  |  |  | 1,549 |  |  |  | 174 |
Unrecognized tax benefits, end of year |  | $ | 6,207 |  |  | $ | 5,245 |  |  | $ | 309 |
The Company believes it is reasonably possible that the total amounts of unrecognized tax benefits will decrease in the following twelve months due to the anticipated settlement of the examination by the Internal Revenue Service; however, actual results could differ from those currently expected. Of the balance of unrecognized tax benefits, $2.1 million would affect the Company’s effective tax rate if recognized at some point in the future. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. As of December 31, 2013 and 2012, the Company has approximately $268,000 and $172,000, respectively, of accrued interest related to uncertain tax positions. Total interest for uncertain tax positions increased by approximately $96,000 in 2013, $100,000 in 2012, and $8,000 in 2011.
