        <ExplanationTxt>SEPA evaluates uncertainty in income tax positions based on the 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, 2024, there were no accruals for uncertain tax positions. If applicable, SEPA records interest and penalties as a component of income tax expense. Tax years from January 1, 2021 through the current year remain open for examination by federal and state authorities.</ExplanationTxt>
