        <Identifier>Description of Uncertain Tax Positions Under FIN 48:</Identifier>
        <ReturnReference>Part X, Line 2:</ReturnReference>
        <Explanation>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, 2013. The Foundation's tax years from 2010 through 2013 are potentially subject to examination.</Explanation>

Additionally, each Trustee of the Foundation who is determined by the Foundation's President to be eligible may participate in the plan. Participants may elect to defer compensation by a specific amount which, for any taxable year, shall not exceed an amount established by the Plan Administrator. The Foundation may, but is not required to, contribute an amount determined in the sole discretion of the Foundation, on behalf of one or more eligible participants for a plan year. Participants are fully vested in the funds credited to their accounts after seven consecutive years of service.

        <Explanation>Schedule L, Part II:The Children's Hospital Pediatric Associates, Inc. (the Foundation) has developed a recruitment loan program for eligible employees as incentive for qualified employees to relocate to certain facilities as demands of the Foundation's practice arise. The loan proceeds are to be used for the purchase of a principal personal residence. The loans are secured by a promissory note and a second mortgage on the residence. The Foundation has provided three loans to two members of the board. However, the Foundation has provided loans to other employees. The loans were made for recruitment and relocation purposes, to assist the physician employees in the purchase of their primary residence. The amounts for the recruitment loans were originally funded by restricted donations provided by Boston Children's Hospital for use in recruitment. The loans will be forgiven over the terms of the notes if the recipients remain employed at the Foundation or its affiliates. If any borrower terminates their employment, the remaining balance becomes immediately due. The amount of the loan forgiveness will be included with accrued interest, if applicable, as compensation in the year forgiven.</Explanation>

        <Explanation>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 PO audit committee shall determine those individuals (including medical staff members) who shall be required to complete the disclosure statement. The PO 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.</Explanation>

        <Explanation>All the physicians (top management, officers, and highly compensated individuals) fall under compensation guidelines determined by Harvard University, with limitations established for certain positions/ranks within the medical school. Annually, compensation is reviewed and reported to Boston Children's Hospital's Board of Trustees to ensure total direct and indirect compensation does not exceed the pre-determined guidelines of Harvard University. 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 aspects 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. This process was followed for the year ended September 30, 2013.</Explanation>
