As such, the Company has recorded a valuation allowance on the portions which are not forecasted to be utilized with the 2020 net operating loss carryback. Additionally, based on similar factors, the Company no longer believes it is more likely than not that the China deferred tax assets will be realized and the Company has recorded a valuation allowance on these deferred tax assets. The Company will continue to evaluate the Company’s ability to realize its deferred tax assets on a quarterly basis.
