The Company has a valuation allowance as of December 31, 2014 of $336,000 against certain of its deferred tax assets. The comparable amount of valuation allowance at December 31, 2013 was $162,000. ASC 740 requires that a valuation allowance be recorded against deferred tax assets when it is more likely than not that some or all of a Company’s deferred tax assets will not be realized based on available positive and negative evidence. At December 31, 2014, total unrecognized tax benefits were $576,000. Of the total, $452,000 of unrecognized tax benefits, if ultimately recognized, would reduce the Company’s annual effective tax rate. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:
|  | 2014 |  |  | 2013 |  |  | 2012 |
Balance at beginning of year |  | $ | 516 |  |  | $ | 421 |  |  | $ | 1,423 |

The Company is subject to income taxes in the U.S. federal and various state, local and foreign jurisdictions. Income tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply. With few exceptions, the Company is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for the years before 2011. The Company has $55,000 of unrecognized tax benefits recorded for periods which the relevant statutes of limitations expire in the next 12 months. The Company has state tax credit carryforwards of $545,000 and $343,000 as of December 31, 2014 and 2013, respectively, set to expire between 2018 and 2025. The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense for all periods presented. The Company accrued approximately $99,000, $85,000 and $91,000 for the payment of interest and penalties at December 31, 2014, 2013 and 2012, respectively. The Company has not provided an estimate for any U.S. or additional foreign taxes on undistributed earnings of foreign subsidiaries that might be payable if these earnings were repatriated since the Company considers these amounts to be permanently invested. It is not practicable to estimate the additional income taxes and applicable withholding taxes that would be payable on remittance of such earnings. In September 2013, the Internal Revenue Service issued final regulations governing the income tax treatment of acquisitions, dispositions, and repairs of tangible property. Taxpayers are required to follow the new regulations in taxable years beginning on or after January 1, 2014. The impact of the regulations is not material to the Company’s consolidated financial statements.
