        <ExplanationTxt>FIN 48 Footnote The Internal Revenue Service has previously determined that the MaineHealth System and its subsidiaries (except Maine Medical Partners (MMP) (a subsidiary of MaineHealth) are organizations as described in Section 501(c)(3) of the Internal Revenue Code (IRC) and are exempt from federal income taxes on related income pursuant to Section 501(a) of the IRC. The MaineHealth System recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount of benefit that is greater than fifty percent likely to be realized upon settlement. Changes in measurement are reflected in the period in which the change in judgment occurs. The MaineHealth System did not recognize the effect of any income tax positions in either 2022 or 2021.</ExplanationTxt>
