        <ExplanationTxt>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). The Foundation is subject to unrelated business tax on its distributive share of profits from Foundation Optical, LLC and Management Services Organization. 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, 2017. The Foundation's tax years from 2014 through 2017 are potentially subject to examination.</ExplanationTxt>

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.

(the PO) and Boston Children's Hospital administer an annual conflict of interest disclosure process to all of their 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 to 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.</ExplanationTxt>

        <ExplanationTxt>All the physicians (top management, officers, and highly compensated individuals) fall under compensation guidelines determined by Harvard University (Harvard), with limitations established for certain positions/ranks within the medical school. Annually, compensation is reviewed and reported to Boston Children's Hospital's (the Hospital's) Board of Trustees to ensure that total direct and indirect compensation does not exceed the pre-determined guidelines of Harvard. Any new indirect benefit plan requires approval by the Foundation's Board of Directors, which then must be reviewed and permitted by the Hospital. Major procedures of the approval process involve: comparing compensation data of physicians within the comparable field of medicine; indirect compensation currently being offered; and the financial stability of the Foundation. Form 990, Part VI, Section B, Line 16a: In January 2007, Children's Hospital Ophthalmology Foundation, Inc. (the Foundation) formed a for-profit limited liability company, Foundation Optical, LLC, to establish a retail optical shop located within a Boston Children's Hospital satellite location. The primary purpose of Foundation Optical, LLC is to offer eyewear needs to patients of the Foundation. The Foundation is the majority owner of Foundation Optical, LLC with a 55% ownership interest. Form 990, Part VI, Section B, Line 16b: It is the policy of Children's Hospital Ophthalmology Foundation, Inc. (the Foundation) to retain an ownership stake in any entity that is consistent with its charitable mission. Further, if the Foundation does retain an ownership stake in any appropriate entity, it will secure legal advice and language in any such operating agreements to ensure it has full authority to prevent and override any action of such entity that the Foundation may determine is inconsistent with its charitable purposes or that may jeopardize the Foundation's tax-exempt status.</ExplanationTxt>
