At December 31, 2014, we had total unused federal tax net operating loss carryforwards of $128.9 million. The expiration dates are as follows (amounts in thousands):
2018 | $ | 1,838 |
2019 | 8,181 |
2020 | 9,662 |
2021 | 8,228 |
2022 | 16,862 |
2023 | 16,173 |
2024 | 17,390 |
2025 | 8,153 |
2026 | 6,792 |
2027 | 3,238 |
2028 | 1,272 |
2029 | 591 |
2031 | 2,784 |
2032 | 8,358 |
2033 | 11,748 |
2034 | 7,662 |
Total | $ | 128,932 |
Of these federal net operating loss carryforwards, $1.2 million were obtained in the acquisition of Annovis, Inc. and may be subject to certain restrictions. Remaining net operating loss carryforwards could be subject to limitations under section 382 of the Internal Revenue Code of 1986, as amended. At December 31, 2014, we had unused state tax net operating loss carryforwards of approximately $46.8 million that expire at various times beginning in 2015. At December 31, 2014, we had unused research and development credit carryforwards of $0.9 million that expire at various times between 2018 and 2028. At December 31, 2014, we had unused foreign net operating loss carryforwards relating to operations in the United Kingdom of approximately $0.9 million with an unlimited carryforward period. A valuation allowance has been provided for the remaining deferred tax assets, due to the cumulative losses in recent years and an inability to utilize any additional losses as carrybacks. We will continue to assess the recoverability of deferred tax assets and the related valuation allowance. To the extent we begin to generate income in future years and it is determined that such valuation allowance is no longer required, the tax benefit of the remaining deferred tax assets will be recognized at such time. Our liability for uncertain tax positions, which was included in other long term liabilities, was $0.1 million and $0.3 million as of December 31, 2014 and 2013, respectively. We recorded less than $0.1 million of additional uncertain tax positions during each of the years ended 2014 and 2013. We recorded $0.2 million and zero for reductions in uncertain tax positions relating to statute of limitations lapse for the years ended 2014 and 2013, respectively. We had no material interest or penalties during fiscal 2014 or fiscal 2013, and we do not anticipate any such items during the next twelve months. Our policy is to record interest and penalties directly related to income taxes as income tax expense in the Consolidated Statements of Operations. We file income tax returns in the U.S. federal jurisdiction, various U.S. state jurisdictions and various foreign jurisdictions. We have statutes of limitation open for Federal income tax returns related to tax years 2011 through 2014. We have state income tax returns subject to examination primarily for tax years 2011 through 2014. To the extent the Company has tax attribute carryforwards, the tax years in which the attribute was generated may still be adjusted upon examination by the Internal Revenue Service, state or foreign tax authorities to the extent utilized in a future period. Open tax years related to foreign jurisdictions remain subject to examination. Our primary foreign jurisdiction is the United Kingdom, which has open tax years for 2011 through 2014.
