“The majority of the CH Neurology 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 1986. At the 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 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 on the PO's rights.”
“The Physicians Organization at Children's Hospital, Inc. (the PO) is a Class "C" member of CH Neurology 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, but not to approve, the annual budgets and 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 modifications to physician compensation and benefit plans for all physician employees of the Foundation.”
“The CH Neurology Foundation, Inc. (the Foundation) has three classes of members. The Chief of the Department of Neurology (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, is a full-time faculty appointment in neurology from Harvard Medical School, and who is geographic full-time at the Hospital shall be a Class "B" member. Upon the recommendation from the Chief, and with the approval of the President of the Hospital, exceptions may be made to permit other physicians who are members of the Foundation to be Class "B" members. The Physicians Organization at Children's Hospital, Inc. is the Class "C" member of the Foundation.”
“According to the Articles of Organization, the Class "A" member is the Chief of the Department of Neurology (the Department) of Boston Children's Hospital (the Hospital). Any member of the Department who holds a medical staff appointment from the Hospital, is a full-time faculty appointment in neurology from Harvard Medical School, and who is geographic full-time at the Hospital shall be a Class "B" member. Class "A and "B" members hold membership as long as they remain qualified for membership. Each member is entitled to one vote upon any question at any meeting of the members.”
“The Physicians Organization at Children's Hospital, Inc. (the PO) is the Class "C" member of CH Neurology 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 upon by the PO and the Foundation. The PO also has the right to review, but not to approve, the annual budgets and by-law changes of the Foundation. Lastly, Boston Children's Hospital also has the right to review for compliance with all applicable laws, the general terms of and any modifications to physician compensation and benefit plans for all physician employees of the Foundation. As a Class "C" member of the Foundation, the PO attends the Foundation's annual meeting.”
“The detailed review will be conducted by the President of the Foundation, Scott L. Pomeroy, MD and the Treasurer and accountant responsible for the books, Frank H. Davis, Jr. A copy of the Form 990 will be provided to the board prior to filing. 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) administers 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 disclosures 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). All persons not receiving a disclosure statement have an affirmative obligation to disclose to the PO President, PO General Counsel, or their supervisor whenever they believe they have or may have a conflict of interest. Similarly, all persons completing a disclosure statement have an affirmative obligation to update the statement any time circumstances change and/or they believe that a conflict of interest may exist. In the event a conflict is found to exist, the Foundation prohibits the member from voting on any matter to which the conflict relates or otherwise influencing 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 the Foundation. The maximum compensation limits are based on pediatric specialty, sub-specialty, academic rank and include productivity adjustments. Any proposed compensation that exceeds the limits must be prospectively 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 CH Neurology Foundation, Inc. (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 Boston Children's Hospital Chief Executive Officer and President/Chief Operating 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.”
“The audit process and scope has not changed from the prior year.”
“The endowment funds represent assets held in trust that are investments whose use has been restricted by donors to a specific 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, 2019. The Foundation's tax years from 2016 through 2019 are potentially subject to examination.”
