Total deferred tax liabilities | $ | 43,363 |  |  | $ | 47,542 |

Long-term deferred tax liabilities | 4,241 |  |  | 5,146 |

Federal, State and Local Net Operating Loss Carryforwards: As a result of the Company’s acquisition of SeQual in 2010, the Company has $22,418 of state net operating losses. California tax law limits the use of these state net operating losses. The remaining state net operating losses expire between 2017 and 2030. In addition, the Company has state net operating losses in various other states which begin to expire in 2017. The gross deferred tax asset for the state net operating losses of $1,646 is substantially offset by a valuation allowance of $1,454. Foreign Net Operating Loss and Tax Credit Carryforwards: As of December 31, 2016, cumulative foreign operating losses of $28,912 generated by the Company were available to reduce future taxable income. Approximately $27,494 of these operating losses expire between 2019 and 2024. The remaining $1,418 can be carried forward indefinitely. The deferred tax asset for the foreign operating losses of $5,903 is substantially offset by a valuation allowance of $5,700. As of December 31, 2016, the Company has $828 of investment tax credits available to reduce its future tax liability. The gross deferred tax asset of $828 is fully offset by a valuation allowance due to uncertainties relating to the Company’s ability to fully use these credits prior to expiration. Other Tax Information The Company has not provided for income taxes on approximately $190,419 of foreign subsidiaries’ undistributed earnings as of December 31, 2016, since the earnings retained have been reinvested indefinitely by the subsidiaries. It is not practicable to estimate the additional income taxes and applicable foreign withholding taxes that would be payable on the remittance of such undistributed earnings. Cash paid for income taxes during the years ended December 31, 2016, 2015, and 2014 was $17,576, $30,492, and $31,208, respectively. Unrecognized Income Tax Benefits The reconciliation of beginning to ending unrecognized tax benefits is as follows:
| Year Ended December 31,
| 2016 |  | 2015 |  | 2014
Unrecognized tax benefits at beginning of the year | $ | 1,024 |  |  | $ | 948 |  |  | $ | 941 |
Additions for tax positions of prior years | — |  |  | 98 |  |  | 358 |
Reductions for tax positions of prior years | (17 | ) |  | — |  |  | (329 | )
Lapse of statutes of limitation | (219 | ) |  | (22 | ) |  | (22 | )
Unrecognized tax benefits at end of the year | $ | 788 |  |  | $ | 1,024 |  |  | $ | 948 |
Included in the balance of unrecognized tax benefits at December 31, 2016 and 2015 were $579 and $714, respectively, of income tax benefits which, if ultimately recognized, would impact the Company’s annual effective tax rate. The Company had accrued approximately $86 and $121 for the payment of interest and penalties at December 31, 2016 and 2015, respectively. The Company accrued approximately $21 and $27 during the years ended December 31, 2016 and 2015, respectively in additional interest associated with uncertain tax positions. The Company is subject to income taxes in the U.S. federal jurisdiction and various state and foreign jurisdictions. 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 years prior to 2012. Due to the expiration of various statutes of limitation, it is reasonably possible the Company’s unrecognized tax benefits at December 31, 2016 may decrease within the next twelve months by approximately $77.
