​ The Company recorded $3.3 million in income tax expense in the three months ended June 30, 2021, and $3.5 million in the six months ended June 30, 2021. The Company recorded no income tax expense during the same periods in 2020. ​ As of December 31, 2020, the Company had recorded a full valuation allowance against its Dutch net deferred tax assets. On May 6, 2021, the CSL Behring Agreement became effective (refer to Note 3 “Collaboration arrangements and concentration of credit risk”). The Company recorded $462.4 million of license revenue related to closing the transaction. The Company intends to record such revenue in its Dutch tax return related to the 12-month period ended December 31, 2020. As such, the Company expects to file a return showing a taxable profit in the Netherlands in 2020, which would result in the consumption of substantially all of its Dutch net operating losses for the years 2011 to 2018. The Company’s remaining Dutch net operating tax losses carried forward would relate to 2019. The Dutch government on June 4, 2021 enacted legislation, whereby such net operating tax losses can be carried forward indefinitely. The Company expects to continue incurring tax losses for the foreseeable future including 2021. As such, the Company retained its full valuation allowance related to the net deferred assets as of June 30, 2021. The adjustment to the Company’s 2020 filing position resulting in the release and consumption of prior year net operating tax losses carried forward was treated as a discrete event in the three months ended June 30, 2021. The Company allocated part of the release to the tax benefit of share issuance cost incurred in 2014, 2015, 2017 and 2018. This resulted in an increase of additional paid-in capital as well as deferred tax expenses of $3.0 million. ​ The Company released its valuation allowance against the Company’s deferred tax assets in the United States as of December 31, 2020. The Company recorded $0.2 million and $0.5 million deferred tax expense in relation to its operations in the United States during the three and six months ended June 30, 2021, respectively. The Company recorded a nil net deferred tax expense in the prior year as it had recorded a valuation allowance against its net deferred tax assets in the United States as of June 30, 2020. ​ The effective income tax rates of respectively -0.8% and -1.0% during the three and six months ended June 30, 2021, is substantially lower than the enacted rated of 25% in the Netherlands as the Company recorded a valuation allowance against its remaining net deferred tax assets in the Netherlands as of December 31, 2020, and June 30, 2021. ​ ​
