        <ExplanationTxt>Heywood Healthcare, Heywood Hospital, Athol, HMGI, Charitable Foundation, Quabbin, and NMTC have been determined to be not-for-profit corporations as described in Section 501(c)(3) of the Internal Revenue Code (the Code), and the Realty Corp. has been determined to be a not-forprofit corporation as described in Section 501(c)(2) of the Code. All of the entities are exempt from federal income taxes on related income pursuant to Section 501(a) of the Code. The Organization annually evaluates its tax status and tax positions taken with respect to its operations and financial position. Under ASC 740, an organization must recognize the financial statement effects of a tax position taken for tax return purposes when it is more likely than not that the position will not be sustained upon examination by a taxing authority. The Organization does not believe it has taken any material uncertain tax positions and, accordingly, it has not recorded any liability for unrecognized tax benefits. Additionally, the Organization has filed IRS Form 990 information returns, as required, and all other applicable returns in jurisdictions where so required. For the year ended September 30, 2025, there was no interest or penalties recorded or included in the consolidated statement of operations.</ExplanationTxt>
