        <FormAndLineReferenceDesc>INFORMATION ABOUT THE SUPPORT ORGANIZATION:</FormAndLineReferenceDesc>
        <ExplanationTxt>SCHEDULE A, PART I, LINE 11G: AMOUNT OF SUPPORT CHA MANAGEMENT SERVICES IS A SUPPORTING ORGANIZATION FOR ITS SOLE CORPORATE MEMBER, THE CAMBRIDGE PUBLIC HEALTH COMMISSION (D/B/A CAMBRIDGE HEALTH ALLIANCE), WHICH IS A PUBLIC INSTRUMENTALITY; CREATED BY ACT OF THE MASSACHUSETTS LEGISLATURE. PART IV, SECTION A, LINE 2: The organization's sole supported organization is the Cambridge Public Health Commission (the "Commission"). The Commission does not have an IRS determination of status under section 509(a)(1) or (2) of the Internal Revenue Code (the "Code") because it is a governmental unit. The Commission was created in 1996 by Chapter 147 of the Acts of 1996 of the Commonwealth of Massachusetts (the "Enabling Act") as "a body politic and corporate." In the Enabling Act, the Massachusetts legislature declared, "[t]he commission is hereby constituted a public instrumentality and the exercise by the commission of the powers conferred by this act shall be deemed and held to be the performance of an essential public function." The Enabling Act further stated that the Commission would be governed and controlled by a board, all of whom would be appointed by the City Manager of Cambridge, and that the Commission would compile and submit an "annual assessment" of existing programs, funding, and proposals for improvements to the City Manager and the City Clerk. Consequently, the Commission is an organization described in section 170(b)(1)(A)(v) and, by extension, section 509(a)(1) of the Code. The Commission operates, supervises, and controls the organization in the same manner that it operates, supervises, and controls, the organization's sister subsidiary, Somerville Hospital. By letter to Somerville Hospital dated July 25, 2013, the Internal Revenue Service stated, "we determined that you are a Type I supporting organization under 509(a)(3). A Type I supporting organization is operated, supervised, or controlled by one or more publicly supported charities." There have been no changes to the Commission's operation, supervision, or control of the organization since July 25, 2013.</ExplanationTxt>
