Note 4 — Income Taxes (Continued) The Company has Net Operating Loss (“NOL”) carryforwards as follows:
Jurisdiction |  | Amount as of December 31, 2015 |  |  | Years of Expiration |
U.S. Federal and state income tax |  | $ | 47,869 |  |  |  | 2018- 2034 |
Foreign |  | $ | 5,719 |  |  |  | 2018-2020 |
Foreign |  | $ | 5,000 |  |  |  | Indefinite |
On April 1, 2014, we acquired all of the stock of GPT in an all cash transaction. The deferred tax assets in 2015 and 2014 related to research and development credits and the offsetting valuation allowance is primarily a result of the GPT acquisition. A portion of the U.S. Federal NOLs were incurred prior to the June 8, 1999 Preferred Financing, which qualified as a change in ownership under Section 382 of the Internal Revenue Code (“IRC”). Due to this change in ownership, the NOL accumulated prior to the change in control can only be utilized against current earnings up to a maximum annual limitation of approximately $591. As a result of the annual limitation, approximately $6,025 remaining of these carryforwards are expected to expire before ultimately becoming available to reduce future tax liabilities in addition to $13,324 in NOLs generated prior to the change in control which have already expired without being utilized. In 2013 through 2015, we incurred NOLs in China and Vietnam associated with the startup activities of new production facilities. In 2015, we incurred a loss in Ukraine associated with foreign currency losses. These NOLs are expected to be utilized in 2016 through 2018 as the locations become profitable. We also incur NOLs in Luxembourg associated with our global holding company structure. Management has concluded that it is more likely than not these NOLs will not be utilized, and thus has not recognized the benefit of these NOLs. We recognize the tax benefit of stock option exercises in excess of compensation expense recorded for financial reporting purposes directly to paid-in capital only when this excess tax benefit provides a reduction to current taxes payable. In certain tax years, our U.S. Federal NOLs completely offset our current Federal tax liability and, therefore, we did not recognize the benefit of tax deductions allowed for stock option exercises in excess of compensation expense recognized for financial reporting purposes. As such, our deferred tax asset related to NOLs is less than the actual NOL available. We recorded this benefit, which totaled $6,681 and $1,831 for 2015 and 2014, respectively, directly to paid-in capital related to stock compensation tax deductions. The U.S. Federal NOL carryforwards include $22,343 relating to deductions taken with respect to stock option exercises in excess of amounts recognized for financial reporting purposes. This portion of the NOL carryforwards is not included as a component of the Company’s deferred tax asset. The earnings before for income taxes and our tax provision are comprised of the following:
|  | Year Ended December 31, |

The Company has recognized deferred taxes related to earnings from foreign subsidiaries, except for certain foreign subsidiaries for which the earnings are permanently reinvested. Quantification of the deferred tax liability, if any, associated with permanently reinvested basis differences is not practicable. The Company is subject to taxation in the United States and various state and foreign jurisdictions. As of December 31, 2015, the Company’s tax years from 2008 through 2015 are subject to examination by the various tax authorities. With limited exceptions, as of December 31, 2015, the Company is no longer subject to U.S. Federal, state, local, or foreign examinations by tax authorities for years before 2008. A U.S. Federal tax audit is currently ongoing for the 2013 tax year, as well as a Michigan state tax audit for the 2011 tax year. Tax audits are currently ongoing in Germany for tax years 2008 through 2011, and Hungary for tax years 2013 and 2014. In 2015, the Company received a tax holiday related to its new operating facility in Macedonia. The benefits under this holiday will expire no later than 2025. At December 31, 2015, 2014 and 2013, the Company had total unrecognized tax benefits of $4,443, $4,651 and $2,241, respectively, all of which, if recognized, would affect the effective income tax rates. The reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:
|  | Year Ended December 31, |
|  | 2015 |  |  | 2014 |  | 2013 |
Balance at beginning of year |  | $ | 4,651 |  |  | $ | 2,241 |  | $ | 2,191 |
Additions based on tax position related to current year |  |  | — |  |  |  | 43 |  |  | 2 |
Additions based on tax positions related to prior year |  |  | 262 |  |  |  | 2,991 |  |  | 580 |
Reductions from settlements and statute of limitation expiration |  |  | (19 | ) |  |  | (432 | ) |  | (599 | )
Effect of foreign currency translation |  |  | (451 | ) |  |  | (192 | ) |  | 67 |
Balance at end of year |  | $ | 4,443 |  |  | $ | 4,651 |  | $ | 2,241 |
The Company classifies income tax-related penalties and net interest as income tax expense. In the years ended December 31, 2015, 2014 and 2013 income tax related interest and penalties were insignificant. The Company believes that it is reasonably possible that there may be a decrease to its unrecognized tax benefits in the next 12 months due to audit settlements and statute expirations, but the amount expected to reverse is insignificant.
