At December 31, 2020 and 2019, the Company had tax effected U.S. federal net operating loss carryforwards of approximately $32.1 million and $31.0 million, respectively, of which $7.8 million tax effected, begin to expire in 2024 but approximately $16.5 million, tax effected, begin to expire in 2035 and $7.8 million, tax effected, have no expiration. At December 31, 2020 and 2019, the Company had tax effected state net operating loss carryforwards of approximately $6.7 million and $6.5 million, respectively. The majority of the state tax losses will not begin expiring until 2035 or later. At December 31, 2020 and 2019, the Company also had U.S. tax credit carryforwards of approximately $0.9 million and $0.9 million, respectively. The tax credits will expire in 2021.

The tax effected foreign net operating loss at December 31, 2020 and 2019 is approximately $3.1 million and $2.9 million, respectively, the majority of which has an unlimited carryforward period.

The Company operates in multiple tax jurisdictions and, in the normal course of business, its tax returns are subject to examination by various taxing authorities. Such examinations may result in future assessments by these taxing authorities. The Company is subject to examination by U.S. tax authorities beginning with the year ended December 31, 2016. The Company is also subject to examination in various foreign jurisdictions. In material foreign jurisdictions, the statute of limitations ranges one – four years from the filing of a tax return.

The Company has not provided for U.S. income and foreign withholding taxes on approximately $13.5 million of certain foreign subsidiaries' undistributed earnings as of December 31, 2020, because such earnings have been retained and are intended to be indefinitely reinvested outside of the U.S. These earnings could become subject to additional tax, if they were remitted as dividends, loaned to the Company, or if the Company should sell its stock in these foreign subsidiaries. However, it is not practicable to estimate the amount of taxes that would be payable for these earnings because such tax, if any, is dependent on circumstances existing if and when a taxable event occurs.

As of December 31, 2020 and 2019, the Company had a valuation allowance of $65.2 million and $51.9 million, respectively, against certain deferred tax assets. The valuation allowance relates to the deferred tax assets of the Company’s U.S. entities, including federal and state tax attributes and timing differences, as well as the deferred tax assets of certain foreign subsidiaries. The increase in the valuation allowance during 2020 is primarily related to operating losses incurred during the year and the limitation on deductibility of interest expense. To the extent the Company determines that, based on the weight of available evidence, all or a portion of its valuation allowance is no longer necessary, the Company will recognize an income tax benefit in the period such determination is made for the reversal of the valuation allowance. If management determines that, based on the weight of available evidence, it is more-likely-than-not that all or a portion of the net deferred tax assets will not be realized; the Company may recognize income tax expense in the period such determination is made to increase the valuation allowance. It is possible that such reduction of or addition to the Company’s valuation allowance may have a material impact on the Company’s results from operations. The U.S. federal and foreign changes to valuation allowance of approximately $9.6 million is presented in the effective tax rate reconciliation as part of the valuation allowance. The U.S. state changes to valuation allowance of approximately $3.8 million is presented as part of the state taxes in the effective tax rate reconciliation as part of the unrecognized tax benefit.

Beginning Balance	$	51,895		$	36,595
Additions	$	14,149		$	15,622
Reductions		(816	)		(322	)
Ending Balance	$	65,228		$	51,895

As of December 31, 2020 and 2019, the total amount of unrecognized tax benefits was $1.0 million and $0 million, respectively, that would favorably impact the Company’s effective income tax rate. However, due to the Company’s determination that the deferred tax asset would not more-likely-than-not be realized, a full valuation allowance was recorded, therefore, zero net impact resulted in the Company’s effective income tax rate. The Company’s uncertain income tax position liability has been recorded to deferred income taxes to offset the tax attribute carryforward amounts. The U.S. federal and foreign changes to uncertain tax positions of approximately $0.6 million is presented in the effective tax rate reconciliation as part of the unrecognized tax benefit. The U.S. state changes to uncertain tax positions of approximately $0.4 million is presented as part of the state taxes in the effective tax rate reconciliation as part of the unrecognized tax benefit.
