Form 990, Part VI, Line 12c Conflict of interest policy	1. Conflict of Interest and Commitment Policy (the "Individual COI Policy"). a. The Individual COI Policy applied to: (i) physicians and scientists with academic appointments at any level; (ii) any clinical provider who could independently write orders or prescriptions; (iii) individuals whose roles included the design, conduct or reporting of research and/or were engaged in human subject research; (iv) administrative employees with independent authority to make purchasing decisions or who were otherwise able to bind, negotiate on behalf, or execute agreements on behalf of, MSK; and (v) individuals that served on MSK institutional committees with responsibility for oversight of research, formulary, or purchasing decisions. b. MSK's Compliance COI Office ("Compliance") and the institutional conflict of interest committee (the "MSK COI Committee") were responsible for the administration of this policy, under the oversight of the committee of the Board (the "Board COI Committee") dedicated exclusively to discharging the Board's responsibility and authority over MSK's conflicts of interest program. c. Upon becoming covered by the Individual COI Policy, annually thereafter and/or as new significant interests arose, an individual was required to disclose financial interests and external relationships and activities ("interests"), whether paid or unpaid, that reasonably appeared to be related to the individual's institutional responsibilities. Covered Persons were required to disclose interests for themselves and immediate family members. d. Depending on the circumstances and based on established criteria, disclosed interests were reviewed by Compliance, the MSK COI Committee, MSK COI Committee designee(s), and/or the Board COI Committee to determine whether an individual conflict of interest existed or presented the perception thereof (i.e. whether an individual financial interest could directly and significantly impact an individual's institutional responsibilities, or an individual's interest could be directly and significantly impacted by their institutional responsibilities). e. The policy required any individual conflict of interest to be managed, reduced or eliminated. When a conflict of interest determination was made, the MSK COI Committee, the MSK COI Committee designee(s), or the Board COI Committee, as applicable, determined how to address it. For those conflicts deemed manageable, management strategies implemented included disclosure of the interest in relevant publications, presentations, consent forms, and educational materials; recusal and/or other limitation on role; independent oversight by a disinterested senior personnel member or committee; and temporary or permanent reduction, divestiture, relinquishment, or termination of an individual's interest. 2. Institutional Conflict of Interest Policy (the "Institutional COI Policy"). a. The Institutional COI Policy applied to financial interests and relationships ("interests") held by MSK as an institution, as well as those financial interests and relationships ("interests") held by senior executive officers deemed "Institutional Officials, their immediate family members. b. Institutional interests held by MSK were made available to Compliance through regular reports from and ongoing engagement with relevant MSK departments. Institutional interests held by Institutional Officials were disclosed through the process described above in the Individual COI Policy, as well as the process described below in the Board COI Policy. c. The MSK COI Committee or MSK COI Committee designee(s) were responsible for determining whether an institutional conflict of interest existed; i.e. whether the institutional interest held by MSK or an Institutional Official (or their immediate family members) could, or could reasonably be perceived to, directly and significantly affect the design, conduct, reporting, review, or oversight of MSK research or the outcome of an MSK activity or decision. d. The policy required any institutional conflict of interest to be managed, reduced or eliminated. When an institutional conflict of interest determination was made, the MSK COI Committee and/or the MSK COI Committee designee(s) determined how to address it. For those conflicts deemed manageable, management strategies implemented included recusal of the applicable Institutional Official from decision-making regarding the arrangement and disclosure to relevant personnel; disclosure of the interest in relevant publications, presentations, consent forms, and educational materials; independent oversight by a disinterested senior personnel member or committee; and temporary or permanent reduction, divestiture, relinquishment, or termination of MSK's or an Institutional Official's institutional interest. 3. Boards of Governing Trustees Conflict of Interest Policy (the "Board COI Policy"). a. The Board COI Policy applied to Board members, officers, and other MSK senior leadership. Individuals covered by the Board COI Policy were required to disclose financial interests and relationships, as defined by the policy, annually and on an ongoing basis. Other entities in the same tax-exempt group had overlapping officers and Board members as described in Schedule O; such persons reported financial interests through this or related processes. b. The Board COI Committee was responsible for determining whether any interest disclosed under the Board COI Policy gave rise to a conflict of interest. The policy required that the members of the Board COI Committee vote, without the individual with the potential conflict present, to determine whether a conflict of interest existed. All members participating in the vote were required to be disinterested with respect to the transaction, arrangement, or relationship. c. The covered individual with the conflict of interest could make a presentation to the Board COI Committee, but could not participate in or influence the discussion of, or vote on, the proposed transaction, arrangement, or relationship. The existence and resolution of any conflict of interest, along with associated determinations made and votes taken, were required to be documented in writing. d. For any transaction, arrangement, or relationship that involved a conflict of interest, a conflict management plan could be implemented if doing so was in the best interests of MSK. Management plans could require disclosure, recusal or other limitation of role, independent oversight and confidentiality.
Form 990, Part VI, Line 15a Process to establish compensation of top management official	MEMORIAL SLOAN-KETTERING CANCER CENTER IS COMMITTED TO ENSURING THAT ITS EXECUTIVE COMPENSATION PROGRAM ADHERES TO THE ESTABLISHED STANDARDS OF REGULATORY COMPLIANCE AND BEST CORPORATE GOVERNANCE. THE BOARD OF TRUSTEES AND GOVERNING TRUSTEES HAS CHARGED THE JOINT HUMAN RESOURCES COMMITTEE (WHICH IS COMPOSED OF INDEPENDENT BOARD MEMBERS WITH NO CONFLICTS OF INTEREST IN REGARD TO EXECUTIVE COMPENSATION) WITH MAKING ALL DECISIONS RELATED TO COMPENSATION FOR OFFICERS AND KEY EMPLOYEES. THE COMMITTEE REVIEWS THE TOTAL COMPENSATION OF THE INDIVIDUALS, INCLUDING BOTH CURRENT AND DEFERRED COMPENSATION, AND ALL EMPLOYEE BENEFITS, ON AN ANNUAL BASIS TO ENSURE THAT THE TOTAL COMPENSATION OF EACH OFFICER AND KEY EMPLOYEE IS REASONABLE. TO ASSIST IN THE COMPLETION OF ITS RESPONSIBILITIES, THE COMMITTEE ENGAGES THE SERVICES OF A NATIONALLY RECOGNIZED CONSULTING FIRM SPECIALIZING IN EXECUTIVE COMPENSATION FOR NOT-FOR-PROFIT HEALTHCARE ORGANIZATIONS. EACH YEAR THE COMMITTEE REVIEWS A COMPREHENSIVE REPORT PREPARED BY THE FIRM THAT INCLUDES MARKET DATA FOR FUNCTIONALLY COMPARABLE ROLES IN COMPARABLE ORGANIZATIONS (I.E., NOT-FOR-PROFIT ACADEMIC/RESEARCH MEDICAL CENTERS, ESPECIALLY THOSE SHARING A MISSION SIMILAR TO MSKCC'S, WITH OTHER HEALTHCARE SECTORS CONSIDERED ON A SELECTED BASIS) AND SUMMARIZES THE RELATIVE MARKET POSITION OF EACH EXECUTIVE'S TOTAL COMPENSATION. THE LAST REVIEW WAS MARCH 2022, WHICH SET THE COMPENSATION FOR THE PERIOD APRIL 2022 TO MARCH 2023. ADDITIONALLY, A SENIOR MEMBER OF THE CONSULTING FIRM ATTENDS THE COMMITTEE'S MEETINGS TO PROVIDE INFORMATION AND TO RESPOND TO QUESTIONS BY THE MEMBERS OF THE COMMITTEE. COMPENSATION LEVELS ARE ESTABLISHED CONSIDERING THE MARKET DATA, AN ASSESSMENT OF PERFORMANCE, AND OTHER BUSINESS JUDGMENT FACTORS, CONSISTENT WITH MSKCC'S EXECUTIVE COMPENSATION PHILOSOPHY. THE COMMITTEE'S DECISIONS ARE MADE IN THE BEST INTERESTS OF MSKCC AND ARE INTENDED TO ENSURE THE RECRUITMENT AND RETENTION OF KEY EXECUTIVE TALENT, CONSISTENT WITH THE MARKET PRACTICES OF OTHER NOT-FOR-PROFIT HEALTHCARE ORGANIZATIONS OF COMPARABLE SCOPE, MISSION AND COMPLEXITY. ON AN ANNUAL BASIS, THE COMMITTEE PROVIDES THE FULL BOARD WITH AN OVERVIEW OF ITS DETERMINATIONS AND PROCESS. THE COMMITTEE'S REVIEW PROCESS FOLLOWS THE INTERMEDIATE SANCTIONS' GUIDELINES FOR QUALIFYING FOR THE REBUTTABLE PRESUMPTION OF REASONABLENESS UNDER SECTION 4958 OF THE INTERNAL REVENUE CODE OF 1986: - THE COMPENSATION ARRANGEMENT IS APPROVED IN ADVANCE BY AN "AUTHORIZED BODY" OF THE APPLICABLE TAX-EXEMPT ORGANIZATION (I.E, THE COMMITTEE, WHICH IS COMPOSED ENTIRELY OF INDIVIDUALS WHO DO NOT HAVE A CONFLICT OF INTEREST WITHIN THE MEANING OF THE REGULATIONS UNDER SECTION 4958). - THE AUTHORIZED BODY OBTAINS AND RELIES UPON "APPROPRIATE DATA AS TO COMPARABILITY" PRIOR TO MAKING ITS DETERMINATION, FOR WHICH COMPARABILITY DATA ARE PROVIDED AND ANALYZED BY SULLIVAN, COTTER AND ASSOCIATES, INC., A WELL-REGARDED EXPERT IN THE AREA OF HEALTHCARE COMPENSATION. THE COMMITTEE ADEQUATELY DOCUMENTS THE BASIS FOR ITS DETERMINATION CONCURRENTLY WITH MAKING THAT DETERMINATION, AGAIN AS REQUIRED IN THE REGULATIONS.
