As of December 31, 2021, it was concluded that it is more likely than not that our U.S. deferred tax assets will be fully realized on the basis of management’s assessment. In evaluating the realizability of our U.S. deferred tax assets, management considered all available evidence and concluded that positive factors, including our sustained profitability and continued improvement in our ability to achieve internal earnings forecasts, outweighed all negative factors, including our history of operating losses (prior to 2015) and historical operating volatility. Our assessment also considered our ability to fully utilize before expiration our domestic net operating loss carryforwards, which expire 2022 thru 2037, and our general business tax credit carryforwards, which expire 2028 thru 2039. As of December 31, 2021, our domestic net operating loss carryforwards and general business tax credits were $44,716 and $2,239, respectively. As of December 31, 2021, for certain past operations in the U.K., we continue to report a valuation allowance for net operating loss carryforwards of approximately $11,000, nearly all of which can be carried forward indefinitely. Management has concluded that utilization of the U.K. net operating losses may be limited due to the change in the past U.K. operation, and that they cannot currently be used to reduce taxable income of our other U.K. subsidiary, Accutronics Ltd. There are no other deferred tax assets related to the past U.K. operations. As of December 31, 2021, we have not recognized a valuation allowance against our other foreign deferred tax assets. There were no unrecognized tax benefits related to uncertain tax positions at December 31, 2021 and 2020. As of December 31, 2021, the Company maintains its assertion that all foreign earnings will be indefinitely reinvested in those operations, other than earnings generated in the U.K. As a result of our operations, we file income tax returns in various jurisdictions including U.S. federal, U.S. state and foreign jurisdictions. We are routinely subject to examination by taxing authorities in these various jurisdictions. In August 2020, the Internal Revenue Service (“IRS”) completed its examination of the Company’s federal tax returns for 2016-2018 with no material adjustments identified. Our U.S. tax matters for 2020 and 2019 remain subject to IRS examination. Our U.S. tax matters for 2002, 2005-2007 and 2011-2015 also remain subject to IRS examination due to the remaining availability of net operating loss carryforwards generated in those years. Our U.S. tax matters for 2002, 2005-2007 and 2011-2020 remain subject to examination by various state and local tax jurisdictions. Our tax matters for the years 2011 through 2020 remain subject to examination by the respective foreign tax jurisdiction authorities.
