Income Taxes
Note 15Income Taxes
The Company and its domestic subsidiaries file a consolidated federal income tax return. Tax liabilities and benefits realized by the consolidated group are allocated as generated by the respective entities.
Deferred income taxes result from temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements that will result in taxable or deductible amounts in future years. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in years in which those temporary differences are expected to be recovered or settled. Deferred tax assets and liabilities are adjusted through income tax expense as changes in tax laws or rates are enacted.
Regulatory tax examinations The Internal Revenue Service (“IRS”) has completed its exam of the
Company’s 2013 through 2016 federal income tax returns. The 2017 and 2018 audit cycle is expected to begin in the first quarter of 2021. Any adjustments that may result from IRS examinations of the Company’s tax returns are not expected to have a material effect on the consolidated financial statements.
Unrecognized tax benefits The Company recognizes tax positions in the consolidated financial statements only when it is more likely than not that the position will be sustained on examination by the relevant taxing authority based on the technical merits of the position. A position that meets this standard is measured at the largest amount of benefit that will more likely than not be realized on settlement. A liability is established for differences between positions taken in a tax return and amounts recognized in the consolidated financial statements.

Although realization is not assured, management believes it is more likely than not that the deferred tax assets will be realized based on the Company’s assessment that the deductions ultimately recognized for tax purposes will be fully utilized. As of December 31, 2020, the Company has U.S. federal and foreign net operating loss carryforwards of $44 million and $68 million, respectively.
The provisions of the Tax Cuts and Jobs Act of 2017 eliminated the 20-year carryforward period and made it indefinite for federal net operating losses generated in tax years after December 31, 2017.  For such amounts generated prior to 2018, the 20-year carryforward period continues to apply.
