        <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). 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, 2021.</ExplanationTxt>

        <ExplanationTxt>The Foundation established the CHMC Anesthesia Foundation, Inc. 2005 Supplemental Executive Retirement Plan (SERP), effective as of January 1, 2005 to reward licensed physician employees with a benefit based on services. The plan was restated on January 1, 2016 to the CHMC Anesthesia Foundation, Inc. 2016 After-Tax Plan (the Plan). Each participant employed on June 30 is allocated 6% of base salary, excluding bonuses and clinical incentive payments, during the Plan year. For the Plan year in which an eligible employee becomes a participant, they will receive an additional contribution equal to 6% of their Plan compensation for each year of service prior to becoming a participant. The Foundation's contributions under the Plan are taxable to the participant as they are made and are not subject to forfeiture if the participant leaves before retiring. Contributions to the Plan will be included as part of taxable wages in the W-2 of each individual. During 2020, the following participants received a contribution that is recorded on the W-2: John H. Arnold, MD, $24,300; Joseph P. Cravero, MD, $174,469; Lynne R. Ferrari, MD, $30,467; Michael L. McManus, MD, $24,420; Kirsten C. Odegard, MD, $22,186; Sulpicio G. Soriano, MD, $29,973; Cynthia Tung, MD, $17,860; Steven Zgleszewski, MD, $19,776; James Dinardo, MD, $31,392; Jeffrey Burns, MD, $41,400; Jue Wang, MD, $13,225; Anjali Koka, MD, $14,797; Sally Vitali, MD, $17,280; Mary Landrigan-Ossar, MD, $19,652; Christine Greco, MD, $22,837; and Carlos Munoz-Sanjulian, MD, $17,929. In addition to the regular annual contribution, the Foundation makes a one-time contribution on behalf of participants first employed by the Foundation after December 21, 2008 after completing seven years of service. The amount of the contribution is $20,000 for each of the seven years in which the participant was a full-time employee (at least 32 hours per week), and $20,000 prorated, based on the participant's full-time equivalent percentage (FTE), for each year in which the participant worked part-time. Any pre-2016 account contributions are fully vested for each participant. The vesting schedule is 50% of post-2016 earnings account amounts vest after ten years of service, 75% vest after fifteen years of service, and amounts are fully invested after twenty years of service. During 2020, a distribution from the After-Tax plan accounts was made to Sulpicio G. Soriano, MD, $10,084 and Michael L. McManus, MD, $10,349. These amounts have been reported in Schedule J, Part II, Column F. Furthermore, as these amounts were reported on previous 990s as part of total compensation earned, they are being disclosed in Schedule J, Part II, Column F.</ExplanationTxt>

        <ExplanationTxt>A majority of CHMC Anesthesia 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 1980. 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.</ExplanationTxt>

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.
