Form 990, Part VI, Section B, line 12c	BCNSP adopts the Conflict of Interest Policy in the form adopted and maintained by the Children's Hospital Corporation, as from time to time in effect. The Organization's conflict of interest policy applies to all directors, Trust Board members, members of the medical or research staff, faculty, fellow, resident, student, visiting faculty or scientist, consultant, volunteers and employees of the Hospital. Directors, chiefs of service and division chiefs, senior directors and others who exercise influence over important strategic, business and purchasing decisions of the Hospital are required to complete an annual conflict of interest disclosure questionnaire about their financial interests and outside activities. If an expected questionnaire is not returned, the Compliance Officer notifies the individual's supervisor or the CEO or COO, and repeated requests for the completed questionnaire are made until the questionnaire is completed. Responses are reviewed by the Compliance Officer and any potential conflicts are discussed with the Office of General Counsel and/or the individual's supervisor; any actual or potential conflicts are managed by termination of the conflict, management of the conflict, recusal, disclosure, review, or a combination thereof. Outside interests and outside activities may be permitted as long as the Hospital, Medical Center or Trust determines that such interests and activities are consistent with the policies of the Hospital, Medical Center or Trust and the Hospital, Medical Center or Trust Board member, medical staff member or employee involved does the following: 1. discloses the fact that he/she has a financial interest or a consultative role in or with a person or company with which the Hospital, Medical Center or Trust is doing or is thinking of doing business; and 2. refrains from voting or exercising any personal influence whatsoever in the selection of a person or company to do business with the Hospital, Medical Center or Trust with whom or in which he/she has a financial interest or a consultative role; and 3. avoids any active participation in any financial negotiations between the Hospital, Medical Center or Trust and the person or company with whom or in which he/she has a financial interest or consultative role; and 4. does not permit such outside interests or activities to absorb such amounts of his/her time and effort as to make it impractical for them to fulfill their assigned responsibilities at the Hospital, Medical Center or Trust; and 5. does not permit such outside interests or activities to compromise or appear to compromise the name or reputation of the Hospital, Medical Center or Trust.
Form 990, Part VI, Section C, line 19	BCNSP adopts the Code of Conduct, the Conflict of Interest Policy, and the Compliance Manual in the form adopted and maintained by the Children's Hospital Corporation, as from time to time in effect.
