State tax returns are filed on a consolidated, combined or separate basis depending on the applicable laws relating to the Company and its subsidiaries. Components of tax expense (benefit) consist of the following:

During the year ended December 31, 2014, 2013, and 2012, there is minimal tax expense recognized. The deferred tax liability resulted in a reduction in the valuation allowance of the Company, as the Company believes the reversal of the deferred tax liability will occur prior to the expiration of the NOL carryforward. During the year ended December 31, 2014, 2013, and 2012, there is minimal tax expense recognized due to state minimum taxes and the Company's valuation allowance. U.S. loss and foreign loss before income taxes are as follows:
|  | Year Ended December 31, |
|  | 2014 |  |  | 2013 |  |  | 2012 |

Based on the Company’s evaluation of current and anticipated future taxable income, the Company believes it is more likely than not that insufficient taxable income will be generated to realize the net deferred tax assets, and accordingly, a valuation allowance has been set against these net deferred tax assets. The Company does not provide for U.S. income taxes for any undistributed earnings of the Company’s foreign subsidiaries, as the Company considers these to be permanently reinvested in the operations of such subsidiaries and have a cumulative foreign loss. At December 31, 2014, 2013 and 2012, these undistributed losses totaled $10.7 million, $9.2 million and $9.5million, respectively. If any earnings were distributed, some countries may impose withholding taxes. However, due to the Company’s overall deficit in foreign cumulative earnings and its U.S. loss position, the Company does not believe a material net unrecognized U.S. deferred tax liability exists. ASC 740 Income Taxes provides that the tax effects from an uncertain tax position can be recognized in the Company’s financial statements only if the position is more-likely-than-not of being sustained on audit, based on the technical merits of the position. Tax positions that meet the recognition threshold are reported at the largest amount that is more-likely-than-not to be realized. This determination requires a high degree of judgment and estimation. The Company periodically analyzes and adjusts amounts recorded for the Company’s uncertain tax positions, as events occur to warrant adjustment, such as when the statutory period for assessing tax on a given tax return or period expires or if tax authorities provide administrative guidance or a decision is rendered in the courts. The Company does not reasonably expect the total amount of uncertain tax positions to significantly increase or decrease within the next 12 months. As of December 31, 2014, the Company’s uncertain tax positions were not significant for income tax purposes. We conduct business globally and, as a result, one or more of the Company’s subsidiaries file income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. In the normal course of business, the Company is subject to examination by taxing authorities throughout the world, including such major jurisdictions as India, Mauritius, and the United States. The Company files a U.S. federal income tax return and tax returns in three U.S. states, as well as in two foreign jurisdictions. Penalties and interest are classified as general and administrative expenses. The following describes the open tax years, by major tax jurisdiction, as of December 31, 2014:
United States — Federal |  | 2005 – present |
United States — State |  | 2005– present |
India |  | 2006 – present |
Mauritius |  | 2006 – present |
As of December 31, 2014, the Company had federal net operating loss carryforwards of approximately $117.0 million and state net operating loss carryforwards of approximately $114.0 million. Included in the federal and state net operating loss carryovers are approximately $0.3 million and $0.2 million of excess stock based compensation related deductions that will be credited to additional paid in capital when the tax benefits realized. The Company also has approximately $1.5 million of alcohol and cellulosic biofuel credit carryforwards. The federal net operating loss and other tax credit carryforwards expire on various dates between 2027 and 2032. The state net operating loss carryforwards expire on various dates between 2027 through 2032. Under the current tax law, net operating loss and credit carryforwards available to offset future income in any given year may be limited by US or India statute regarding net operating loss carryovers and timing of expirations or upon the occurrence of certain events, including significant changes in ownership interests. The Company’s India subsidiary also will have net operating loss carryforwards as of March 31, 2015, its tax fiscal year end, of approximately $10 million in US dollars, which expire from March 30, 2016 to March 30, 2023.
