“A majority of Boston Children's Heart Foundation, Inc.'s (the Foundation's) board members are physicians who are not independent from the Foundation. However, the Foundation is part of an integrated delivery system with Boston Children's Hospital (the Hospital) which does have a community board. The Foundation was organized in 1983. At that time, the board was composed entirely of physicians, a board structure that was approved by the Internal Revenue Service. The Foundation has since adjusted the board structure to make it more responsive to the Hospital by adding the Physicians Organization at Children's Hospital Inc. (the PO) as a member. See Schedule O, Part VI, Questions 3, 6, 7b, and 12 for more details on the PO's rights.”
“The Physicians Organization at Children's Hospital, Inc. (the PO) is the Class "C" member of Boston Children's Heart Foundation, Inc. (the Foundation). The PO is responsible for providing management services to the Foundation. The PO has the power to approve the independent auditor and legal counsel of the Foundation from an approved list of firms mutually agreed to by the PO and the Foundation. The PO also has the right to review the annual budgets and review and approve the by-law changes of the Foundation. Lastly, Boston Children's Hospital has the right to review for compliance with applicable law, the general terms of and any modification to physician compensation and benefit plans for all physician employees of the Foundation.”
“Boston Children's Heart Foundation, Inc. (the Foundation) has three classes of members. The Chief of the Department of Cardiology (the Chief) of Boston Children's Hospital (the Hospital) is the Class "A" member. Any member (other than the Chief) who holds a medical staff appointment from the Hospital, a full-time faculty appointment in cardiology from Harvard Medical School, and who is geographically full-time at the Hospital shall be a Class "B" member. The Physicians Organization at Children's Hospital, Inc. is the Class "C" member of the Foundation.”
“The Cardiologist-in-Chief of Boston Children's Hospital (the Hospital) is the Class "A" member of Boston Children's Heart Foundation, Inc. (the Foundation). Every member of the Foundation who holds a medical staff appointment from the Hospital, has a full-time faculty appointment under the auspices of the Cardiologist-in-Chief from Harvard University Medical School, and who practices medicine primarily at the Hospital, shall be a Class "B" member. According to the Articles of Organization, the Class "A and "B" members appoint/elect the board members of the Foundation at the annual meeting.”
“The Physicians Organization at Children's Hospital, Inc. (the PO) is the Class "C" member of Boston Children's Heart Foundation, Inc. (the Foundation). The PO is responsible for providing management services to the Foundation. The PO has the power to approve the independent auditor and legal counsel of the Foundation from an approved list of firms mutually agreed to by the PO and the Foundation. The PO also has the right to review the annual budgets and review and approve the by-law changes of the Foundation. Lastly, Boston Children's Hospital has the right to review for compliance with applicable laws, the general terms of and any modification to physician compensation and benefit plans for all physician employees of the Foundation.”
“The detailed review will be conducted by the President of the Foundation, Tal Geva, MD; the administrator, Marissa Densmore; and the Director of Financial Ops/Controller, Joseph Cantlin. A copy of Form 990 will be available to the board. The Physicians Organization at Children's Hospital, Inc. will review the Form 990 with the board members. The detailed review will be conducted before filing the return with the Internal Revenue Service.”
“The Physicians Organization at Children's Hospital, Inc. (the PO) and Boston Children's Hospital (the Hospital) administer an annual conflict of interest disclosure process to all of its member Foundations, which asks physicians (officers, top management, and highly compensated employees) and selected Foundation staff to disclose potential conflicts. A disclosure statement will be circulated annually to members of the PO. The audit committee shall determine those individuals (including medical staff members) who shall be required to complete the disclosure statement. The audit committee, at its discretion, may either: 1) refer any or all disclosure statements to the Board of Directors; 2) appoint an ad hoc committee to review and resolve any conflict of interest issues; or 3) review and resolve any conflict of interest issues personally or through a designee(s). Any person not receiving a disclosure statement nevertheless has an affirmative obligation to disclose to the PO President, PO General Counsel, or his/her supervisor whenever he/she believes he/she has or may have a conflict of interest. Similarly, each person completing a disclosure statement has an affirmative obligation to update the statement any time circumstances change and/or he/she believes that a conflict of interest may exist. In the event a conflict of interest is found to exist, the Foundation prohibits the member from voting on any matter to which the conflict relates or otherwise influence the voting on such matter.”
“Faculty compensation must comply with the Boston Children's Hospital (the Hospital) Physician Compensation Guidelines. These guidelines are developed in consultation with an independent external compensation consulting firm and are approved by the independent Compensation Committee of the Board of Children's Medical Center Corporation and the Hospital. The guidelines set the maximum compensation limits based on a peer group analysis for Boston Children's Heart Foundation, Inc. (the Foundation). The maximum compensation limits are based on pediatric specialty, sub-specialty, academic rank and approved by the independent Compensation Committee of the Board of the Hospital. Annual compensation for individual faculty members is set by the President of the Foundation, reviewed and approved by the Foundation in accordance with the Foundation's compensation policies and procedures. The Foundation's President's compensation is reviewed and approved annually on a prospective basis by the Hospital's President/Chief Executive Officer.”
“The Foundation maintains all financial records, conflict of interest policies, and governing documents at its main office at 300 Longwood Avenue, Boston, MA 02115. The documents are available upon request.”
“Pension adjustment 274,980. Net asset transfer to affiliate -25,334,000.”
“The audit process and scope has not changed from the prior year.”
“Assets limited to use represent assets held in trust that are available to pay for future benefits to participants for deferred compensation benefit plans and investments whose use has been restricted by donors to a specific time period or purpose.”
“The Foundation is a tax-exempt corporation as described in Section 501(c)(3) of the Internal Revenue Code (the Code), and is exempt from federal income taxes on related income pursuant to Section 501(a) of the Code. In addition, the Foundation qualifies for the charitable contribution deduction under Section 170(b)(1)(A), and has been classified as an organization that is not a private foundation under Section 509(a)(2). Tax-exempt organizations could be required to record an obligation for income taxes as the result of a tax position they have historically taken on various tax exposure items, including unrelated business income or tax status. Management of the Foundation has evaluated the positions taken on the Foundation's filed tax returns and has concluded that no uncertain income tax positions exist at September 30, 2024.”
