​ The Company has recorded a valuation allowance, as a result of uncertainties related to the realization of its net deferred tax asset, at December 31, 2020 and 2019 of approximately $171.6 million and $118.7 million, respectively. A reconciliation of the current year change in valuation allowance is as follows (in thousands): ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | U.S. |  | Foreign |  | Total |
Increase in valuation allowance for current year increase in net operating losses | ​ | $ | 51,848 | ​ | $ | ​ | ​ | $ | 51,848 | ​

Net increase in valuation allowance | ​ | $ | 52,412 | ​ | $ | 505 | ​ | $ | 52,917 | ​
​ The deferred tax assets have been offset by a full valuation allowance because it is more likely than not that the tax benefits of the net operating loss carryforwards and other deferred tax assets may not be realized due to cumulative losses. ​ Under Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), the use of loss carryforwards may be limited if a change in ownership of a company occurs. If it is determined that due to transactions involving the Company’s shares owned by its 5 percent or greater stockholders a change of ownership has occurred under the provisions of Section 382 of the Code, the Company's federal and state NOL carryforwards could be subject to significant Section 382 limitations. ​ Based on studies of the changes in ownership of the Company, it has been determined that an ownership change under Section 382 of the Code occurred in 2013 that limited the amount of pre-change NOL that can be used in future years to $13.5 million. These NOL carryforwards will expire, if unused, at various dates from 2020 through 2033. NOLs of $450.9 million incurred after the most recent ownership change are not subject to Section 382 of the Code and are available for use in future years. Accordingly, the Company's deferred tax assets include $464.4 million of U.S. net operating loss carryforwards. The NOL carryforwards available at December 31, 2020, include $205.2 million of NOL that was generated in 2020, $25.0 million of net operating loss that was generated in 2019 and $43.4 million of NOL that was generated in 2018 that do not expire (2019 and 2018 as restated). The remainder, if unused, will expire at various dates from 2032 through 2037. ​ Approximately $4.4 million of research credit carryforwards generated after the most recent IRC Section 382 ownership change are included in the Company's deferred tax assets. Due to limitations under IRC Section 382, research credit carryforwards existing prior to the most recent IRC Section 382 ownership change will not be used and are not reflected in the Company's gross deferred tax asset at December 31, 2020. The remaining credit carryforwards will expire during the periods 2033 through 2040. ​ At December 31, 2020, the Company has unused Canadian net operating loss carryforwards of approximately $14.0 million. The net operating loss carryforwards if unused will expire at various dates from 2026 through 2034. At December 31, 2020, the Company has Scientific Research and Experimental Development (“SR&ED”) expenditures of $17.2 million available to offset future taxable income. These SR&ED expenditures have no expiry date. At December 31, 2020, the Company has Canadian ITC credit carryforwards of $1.3 million available to offset future income tax. These credit carryforwards if unused will expire at various dates from 2022 through 2028. ​ At December 31, 2020, the Company has unused French net operating loss carryforwards of approximately $21.3 million. The net operating loss may carryforward indefinitely or until the Company changes its activity. ​ As of December 31, 2020, the Company has no un-repatriated foreign earnings or unrecognized tax benefits. ​ The Company files 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. Open tax years in the US range from 2017 and forward. Open tax years in the foreign jurisdictions range from 2010 to 2019. However, upon examination in subsequent years, if net operating losses carryforwards and tax credit carryforwards are utilized, the US and foreign jurisdictions can reduce net operating loss carryforwards and tax credit carryforwards utilized in the year being examined if they do not agree with the carryforward amount. As of December 31, 2020, the Company was not under audit in the U.S. or non-U.S. taxing jurisdictions. ​ The Company recognized an income tax benefit for the year ended December 31, 2020 of $30.8 million resulting from a source of future taxable income attributable to the net credit to additional paid-in capital of $25.6 million related to the issuance of the 3.75% Convertible Senior Notes, offset by the partial extinguishment of the 5.5% Convertible Senior Notes and $5.2 million of income tax benefit for the year ended December 31, 2020 related to the recognition of net deferred tax liabilities in connection with the Giner ELX acquisition. This resulted in a corresponding reduction in our deferred tax asset valuation allowance. The Company has not changed its overall conclusion with respect to the need for a valuation allowance against its net deferred tax assets, which remain fully reserved.
