The Company has Net Operating Loss (“NOL”) carryforwards as follows:
Jurisdiction |  | Amount as of December 31, 2012 |  |  | Years of Expiration |
U.S. Federal income tax |  | $ | 10,165 |  |  |  | 2012 - 2023 |
State income taxes |  | $ | 4,002 |  |  |  | 2014 - 2016 |
All 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 NOL’s generated prior to the change in control which have already expired without being utilized. Consequently, the related valuation allowance decreased by $1,503 during 2012. During 2010, we completed a study related to the 1999 change in control limitation amount and determined that an additional $4,044 NOL’s subject to the limitation were utilizable during 2010. We reversed the portion of the valuation allowance related to this adjustment totaling $1,375. A second change in control took place on September 22, 2006 when an accumulation of trades of the Company’s Common Stock by certain of the Company’s large shareholders exceeded a three year cumulative amount of 50% of the Company’s total Common Stock outstanding. The resulting annual change in control limitation of approximately $8,135 did not have an impact on the utilization of the amounts of the NOLs subject to this limitation. Since our NOLs offset our current federal tax liability, we do not recognize for book purposes deductions allowed for stock option exercises in excess of that recorded for book purposes. As such, our deferred tax asset for book purposes related to NOLs is less than the actual NOL available. During 2011, our taxable income exceeded the remaining amount of NOLs recorded for book purposes representing a benefit attributable to deductions taken for tax purposes on stock option exercises. We recorded this benefit which totaled $171 and $3,275 for 2012 and 2011, respectively, directly to paid-in capital. The earning before for income taxes and our tax provision are comprised of the following:
|  | Year Ended December 31, |
|  | 2012 |  |  | 2011 |  |  | 2010 |
Income before income taxes: |  |  |  |  |  |  |  |  |  |  |  |

Foreign |  |  | 28,937 |  |  |  | 3,646 |  |  |  | 585 |
Total income before income taxes |  | $ | 32,672 |  |  | $ | 15,869 |  |  | $ | 11,408 |
|  | Year Ended December 31, |

Federal |  | $ | 1,834 |  |  | $ | 2,378 |  |  | $ | 1,847 |
State and local |  |  | 348 |  |  |  | 182 |  |  |  | (284 | )
Foreign |  |  | (1,393 | ) |  |  | (3,159 | ) |  |  | — |
Total deferred income tax expense |  | $ | 789 |  |  | $ | (599 | ) |  | $ | 1,563 |
Total tax expense |  | $ | 8,351 |  |  | $ | 4,666 |  |  | $ | 2,609 |
The Company’s earnings outside the US are permanently reinvested. With respect to the German operations all amounts are permanently reinvested other than the earnings of certain jurisdictions for which deferred income taxes have been provided. Quantification of the deferred tax liability, if any, associated with indefinitely reinvested basis differences is not practicable. The American Taxpayer Relief Act of 2012 (“the Act”) was signed into law on January 2, 2013. The Act retroactively restored the research and development credit and certain exemptions under the foreign income tax rules. Because a change in tax law is accounted for in the period of enactment, the retroactive effect of the Act on the Company’s U.S. federal taxes for 2012, a benefit of approximately $1.3 million will be recognized in 2013. The Company is subject to U.S. federal income tax as well as income tax in multiple foreign and state jurisdictions. During 2010, the Internal Revenue Service (“IRS”) completed a review of our 2007 and 2008 Federal Income Tax Returns. Our 2010 and 2011 Federal tax returns are currently under audit. No state tax returns are currently under examination. The reconciliation of the beginning and ending amount of unrecognized tax benefits that would favorably affect the effective income tax rate in the future periods is as follows:
|  | Year Ended December 31, |
|  | 2012 |  |  | 2011 |
Balance at beginning of year |  | $ | 1,678 |  |  | $ | 500 |
Additions based on tax position related to current year |  |  | 67 |  |  |  | 63 |
Additions based on tax positions related to prior year |  |  | 413 |  |  |  | — |
Amount acquired with W.E.T Acquisition |  |  | — |  |  |  | 1,216 |
Effect of foreign currency translation |  |  | 33 |  |  |  | (101 | )
Balance at end of year |  | $ | 2,191 |  |  | $ | 1,678 |
