        <ExplanationTxt>The Science Center is a tax-exempt organization under Section 501(c)(3) of the Internal Revenue Code, although its consolidated entities, the Park, PTI, and SCEC, are for profit entities which are subject to income taxes. During each of the years ended December 31, 2023 and 2022, the total federal and state income tax expense from the consolidated entities was $0. U.S. GAAP requires management to evaluate tax positions taken and recognize a tax liability if the Center has taken an uncertain tax position that more likely than not would not be sustained upon examination by a government authority. Management has analyzed the tax positions taken by the Center, and has concluded that as of December 31, 2023 and 2022, there are no uncertain positions taken or expected to be taken that would require recognition of a liability or disclosure in the consolidated financial statements. The Center would recognize future accrued interest and penalties related to unrecognized tax benefits and liabilities in income tax expense if such interest and penalties are incurred. There were no income tax related interest and penalties recorded for either of the years ended December 31, 2023 or 2022.</ExplanationTxt>
