        <ExplanationTxt>SIIM evaluates uncertainty in income tax positions based on a more-likely-than-not recognition standard. If that threshold is met, the tax position is then measured at the largest amount that is greater than 50% likely of being realized upon ultimate settlement. As of December 31, 2023 and 2022, there are no accruals for uncertain tax positions. If applicable, SIIM records interest and penalties as a component of income tax expense. Tax years from 2020 through the current year remain open for examination by tax authorities.</ExplanationTxt>
