​ The Company has recognized deferred taxes related to foreign withholding taxes and the expected foreign currency impact upon repatriation from foreign subsidiaries not considered indefinitely reinvested. At December 31, 2021, the aggregate undistributed earnings of our foreign subsidiaries amounted to $43,530. Based on the Company’s review of both positive and negative evidence regarding the realizability of deferred tax assets at December 31, 2021, a valuation allowance is recorded against certain deferred tax assets based upon the conclusion that it was more likely than not they would not be realized. The Company has net operating loss carry forwards of $76,986 and $53,761 for state and foreign tax jurisdictions, respectively. The state net operating losses expire from 2030-2041 or have indefinite lives and the foreign net operating losses expire from 2022-2026 or have indefinite lives. The Company has general business and foreign tax credit carry forwards of $22,087, $963 and $1,122 for U.S. federal, state and foreign jurisdictions, respectively. The U.S. federal general business credits, if unused, begin to expire in 2025, and the state and foreign tax credits expire at various times. The following is a reconciliation of the Company’s total gross unrecognized tax benefits: ​

Balance as of December 31 | ​ | $ | 2,891 | ​ | $ | 3,449 | ​ | $ | 3,449
​ At December 31, 2021, the Company has classified $2,891 as a reduction to non-current deferred income tax assets. If the Company’s tax positions are sustained by the taxing authorities in favor of the Company, the amount that would affect the Company’s effective tax rate is approximately $2,891 and $3,449 at December 31, 2021 and 2020, respectively. The Company classifies interest expense and, if applicable, penalties which could be assessed related to unrecognized tax benefits as a component of income tax expense. For the years ended December 31, 2021, 2020 and 2019, the Company recognized approximately $0, $0 and $(5) of gross interest and penalties, respectively. The Company conducts business globally and, as a result, 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 throughout the world. The following table summarizes the open tax years for each jurisdiction: ​
