The Company records a valuation allowance when it is more-likely-than-not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of the deferred tax assets depends on the ability to generate sufficient taxable income of the appropriate character in the future and in the appropriate taxing jurisdictions. If the Company was to determine that it would be able to realize the deferred tax assets in the future in excess of their net recorded amount, the Company would make an adjustment to the valuation allowance, which would reduce the provision for income taxes. At December 31, 2020, the valuation allowance primarily relates to federal and foreign capital loss carryforwards. The following summarizes changes in the balance of valuation allowances on deferred tax assets (in thousands):
| Years Ended December 31,

As of December 31, 2020, the Company had recorded a total tax benefit of $16.9 million related to federal and state research and development tax credits. This benefit is partially offset by $5.1 million uncertain tax position due to the uncertainty related to the realizability of the federal research and development tax credits. To the extent penalties and interest would be assessed on any underpayment of income tax, such accrued amounts are classified as a component of income tax provision (benefit) in the consolidated financial statements consistent with Company's policy. For the year ended December 31, 2020, the Company did not record any tax expense for interest and penalties related to uncertain tax positions. The Company is subject to taxation in the United States, various states, and foreign jurisdictions. The Company has significant operations in the United States and Canada and to a lesser extent in various other international jurisdictions. Tax years that remain subject to examination vary by legal entity but are generally open in the United States for the tax years ended after 2012 and outside the United States for the tax years ended after 2012.
