        <ReturnReference>SCHEDULE J, PART III</ReturnReference>
        <Explanation>Included in Other Reportable Compensation are certain distributions from deferred compensation plans that the Institution maintains for certain highly compensated management and professional employees. These grandfathered plans were adopted in the early and mid-1980s and have been closed to new participants since August 16, 1986. The grandfathered plans allowed participants to irrevocably defer portions of their approved salary until certain conditions were met, typically retirement or disability. In addition, the Institution made contributions to the plans to the extent contributions to the MSKCC Retirement Plan for such participants were limited by applicable contribution limits under the Internal Revenue Code. The Institution provided participants with the opportunity to receive distributions as permitted under Section 409A of the Internal Revenue Code. This opportunity was exercised by numerous participants. These distributed amounts were reported in 2010 as W-2 compensation. 100 percent of these amounts reflect the deferral of a portion of the participant's approved compensation package and related investment experience since the commencement of an individual's plan participation. As contributions were made to these plans for previous periods, the contribution amounts were reported on Form 990 for the applicable period as contributions to deferred compensation plans with respect to officers, key employees, and other highest paid employees. These amounts, as adjusted for investment experience, are reported again now on Form 990 as distributions from the plans.</Explanation>

Individuals covered by this policy have a duty to disclose Financial Interests, as defined by the Policy, annually and as they arise. In the event a covered individual is involved in a Board or committee action (such as approval of a transaction or arrangement) and the individual has a Financial Interest related to the matter before the Board, the individual must disclose the Financial Interest and all material facts to the Board or committee. The individual must leave the meeting while the determination of a conflict of interest is discussed and voted upon, and the remaining, disinterested Board or committee members are responsible to decide if a conflict exists. If a determination is made that a conflict exists, the involved individual may make a presentation to the Board or committee but s/he must leave the meeting during the discussion of and the vote on the transaction or arrangement. The Board or committee is required to determine whether MSKCC can obtain a more advantageous transaction or arrangement with reasonable efforts from an unconflicted person or entity. As appropriate, the chairperson of the Board or Committee is responsible to appoint a disinterested person or committee to investigate alternatives to the proposed transaction or arrangement.</Explanation>

        <ReturnReference>FORM 990, PART VI, LINE 15</ReturnReference>
        <Explanation>MEMORIAL SLOAN-KETTERING CANCER CENTER (MSKCC) IS COMMITTED TO ENSURING THAT ITS EXECUTIVE COMPENSATION PROGRAM ADHERES TO THE ESTABLISHED STANDARDS OF REGULATORY COMPLIANCE AND BEST CORPORATE GOVERNANCE. THE MSKCC BOARD OF OVERSEERS AND MANAGERS HAS CHARGED THE JOINT HUMAN RESOURCES COMMITTEE (WHICH IS COMPOSED OF INDEPENDENT BOARD MEMBERS WITH NO CONFLICTS OF INTEREST IN REGARDS 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, WITH OTHER HEALTHCARE SECTORS CONSIDERED ON A SELECTED BASIS) AND SUMMARIZES THE RELATIVE MARKET POSITION OF EACH EXECUTIVE'S TOTAL COMPENSATION. 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.</Explanation>

        <Identifier>STRATEGIC PLANNING AND COMMUNITY BENEFITS</Identifier>
        <Explanation>THE FOLLOWING NOTES ON STRATEGIC PLANNING AND COMMUNITY BENEFITS PERTAIN TO MEMORIAL SLOAN-KETTERING CANCER CENTER AND ITS AFFILIATED INSTITUTIONS AS REPORTED ON A COMBINED BASIS WITH A SEPARATE GROUP 990 FILING UNDER EIN 91-2154236. MEMORIAL SLOAN-KETTERING CANCER CENTER AND ITS AFFILIATES ARE INTERTWINED WITH COMMUNITY BENEFITS AND CHARITY CARE ACTIVITIES AS OUTLINED BELOW. STRATEGIC PLANNING MSKCC'S STRATEGIC PLANNING PROCESS INCLUDES DEVELOPING SERVICES AND PROGRAMS IN RESPONSE TO CANCER MORBIDITY AND MORTALITY DATA, DEMOGRAPHIC DATA, PATIENT AND PROGRAM SATISFACTION SURVEYS, AND COMMUNITY INPUT. THESE FINDINGS AND RESULTS ARE USED TO PLAN INITIATIVES AND PROGRAMS AIMED AT IMPROVING OUR COMMUNITY'S ACCESS TO CANCER INFORMATION, PREVENTION, CARE, AND TREATMENT ADVANCES. IN ADDITION, THE CENTER'S STRATEGIC EFFORTS ARE FOCUSED ON REDUCING THE CRITICAL ISSUE OF CANCER HEALTH DISPARITIES AMONG MINORITY AND MEDICALLY UNDERSERVED POPULATIONS. MEMORIAL HOSPITAL'S PRIMARY CATCHMENT AREA ENCOMPASSES 23 COUNTIES ACROSS LONG ISLAND, SOUTHERN NEW YORK STATE, NORTHERN NEW JERSEY, SOUTHWESTERN CONNECTICUT, AND THE FIVE BOROUGHS OF NEW YORK CITY. EACH OF THESE COUNTIES WAS IDENTIFIED AS HAVING A MINIMUM OF 50 OR MORE MEMORIAL HOSPITAL PATIENTS RESIDING IN THE AREA. IN 2011, THERE WERE 24,486 ADMISSIONS TO MEMORIAL HOSPITAL AND 535,900 OUTPATIENT VISITS WERE CONDUCTED AT LOCATIONS THROUGHOUT MANHATTAN AND REGIONAL SITES IN WESTCHESTER COUNTY, LONG ISLAND, AND NORTHERN NEW JERSEY. IN TOTAL, 123,140 PATIENTS WERE SEEN AT MSKCC FACILITIES: 112,057 (91%) FROM THE TRI-STATE AREA (NY, NJ, CT); 9,728 (8%) FROM OTHER PARTS OF THE U.S. AND 1,355 (1%) INTERNATIONAL PATIENTS. SINCE 1987, MSKCC HAS HAD A FINANCIAL ASSISTANCE PROGRAM IN PLACE TO ASSIST UNDERINSURED AND UNINSURED PATIENTS WHO ARE EXPERIENCING DIFFICULTIES MEETING THEIR FINANCIAL RESPONSIBILITIES TO MEMORIAL HOSPITAL AND ITS PHYSICIANS. FINANCIAL COUNSELORS ARE AVAILABLE TO WORK WITH PATIENTS AND INSURANCE COMPANIES - INCLUDING MEDICARE AND MEDICAID - TO HELP THE PATIENTS TO ACCESS SERVICES. FOR THOSE WHO DON'T QUALIFY FOR PUBLICLY AVAILABLE HEALTH INSURANCE OR WHO ARE UNABLE TO PAY THEIR PORTION OF FEES ABOVE INSURANCE REIMBURSEMENT, MEMORIAL SLOAN-KETTERING CAN PROVIDE FINANCIAL HELP TO THOSE WHO ARE ELIGIBLE THROUGH ITS FINANCIAL ASSISTANCE PROGRAM. THE PREMISE OF THIS PROGRAM IS THAT ALL PATIENTS ARE EXPECTED TO CONTRIBUTE TO THEIR CARE BASED ON THEIR ABILITY TO PAY. FINANCIAL ASSISTANCE AND CHARITY CARE THE FINANCIAL ASSISTANCE PROGRAM EMPLOYS SEVERAL STRATEGIES TO INCREASE PATIENT AWARENESS OF THE PROGRAM. THESE EFFORTS INCLUDE PLACEMENT OF PROGRAM BROCHURES IN ALL PATIENT REGISTRATION AREAS; MAILING OF NOTIFICATION INSERTS IN EACH PATIENT'S FIRST BILL, SUBSEQUENT MONTHLY MEDICAL BILLS, AND COLLECTION NOTICES; AND ONGOING TRAINING FOR BILLING DEPARTMENT STAFF ON COMMUNICATING FINANCIAL ASSISTANCE SERVICES. DURING THE REGISTRATION PROCESS, FINANCIAL INTERVIEWERS EDUCATE PATIENTS ON THE VARIOUS PROGRAMS THAT ARE AVAILABLE TO THEM, INCLUDING GOVERNMENTAL PROGRAMS AND THE INSTITUTION'S CHARITY CARE PROGRAMS, CONTINGENT UPON THEIR ELIGIBILITY CRITERIA. INFORMATION ABOUT THE INSTITUTION'S FINANCIAL ASSISTANCE PROGRAM IS ALSO AVAILABLE ON ITS WEBSITE: HTTP://WWW.MSKCC.ORG/MSKCC/HTML/74331.CFM A PATIENT WITH INCOME LESS THAN OR EQUAL TO 500% OF THE FPL IS ELIGIBLE FOR THE INSTITUTION'S FINANCIAL ASSISTANCE PROGRAM. FOR INSTANCE, THE INSTITUTION MAY REDUCE THE FEES INCURRED BY THE PATIENT OR ACCEPT AS FULL PAYMENT AMOUNTS PAID BY THE INSURANCE CARRIER ON THE PATIENT'S BEHALF. A PATIENT MAY ALSO QUALIFY FOR ASSISTANCE EVEN IF HIS/HER INCOME IS GREATER THAN THE THRESHOLD LIMIT. THIS IS BECAUSE THE INSTITUTION ADJUSTS PATIENTS' INCOME FOR ROUTINE MONTHLY EXPENSES, INCLUDING TAXES, TO DETERMINE DISPOSABLE INCOME. MSKCC ALSO DEDUCTS A SPECIFIC AMOUNT (DEBT BURDEN) AS A MONTHLY CLOTHES AND FOOD ALLOWANCE BASED ON A PATIENT'S FAMILY SIZE IN EVALUATING THE TYPE AND AMOUNT OF ASSISTANCE NEEDED. THE TABLES BELOW ILLUSTRATE THE INCOME GUIDELINES USED IN EVALUATING A PATIENT'S FINANCIAL STATUS. MSKCC 2011 INCOME GUIDELINES: FAMILY ALLOWED RESOURCE FOOD &amp; CLOTHING SIZE INCOME LEVELS ALLOWANCE 1 $54,450 $29,250 $1,147 2 $73,550 $35,850 $1,431 3 $92,650 $38,978 $1,641 4 $111,750 $42,105 $1,859 5 $130,850 $45,233 $2,062 6 $149,950 $48,360 $2,279 CHARITY CARE REPRESENTS THE COST OF SERVICES PROVIDED TO PATIENTS WHO CANNOT AFFORD HEALTH CARE SERVICES DUE TO INADEQUATE RESOURCES AND/OR ARE UNINSURED OR UNDERINSURED. A PATIENT IS CLASSIFIED AS A CHARITY CARE PATIENT IN ACCORDANCE WITH THE INSTITUTION'S ESTABLISHED POLICIES AND WHERE INSUFFICIENT PAYMENT FOR SUCH SERVICES IS ANTICIPATED. THE INSTITUTION CONSIDERS PATIENTS FOR CHARITY CARE IF HOUSEHOLD INCOME IS LESS THAN 500% OF THE FEDERAL POVERTY GUIDELINES. SERVICES PROVIDED AS CHARITY CARE ARE NOT REPORTED AS REVENUE. MSKCC ENGAGES IN AND SUPPORTS COALITION BUILDING ACTIVITIES THAT PROMOTE THE HEALTH OF THE COMMUNITIES THE INSTITUTION SERVES. STAFF MEMBERS ARE ENCOURAGED TO SHARE THEIR CLINICAL EXPERTISE AND EXPERIENCE WITH PARTNERING HEALTHCARE FACILITIES AND COMMUNITY ORGANIZATIONS. STAFF MEMBERS SERVE AND PARTICIPATE IN NUMEROUS COMMUNITY GROUPS INCLUDING THE AMERICAN CANCER SOCIETY, THE AMERICAN PUBLIC HEALTH ASSOCIATION, THE GREATER NEW YORK HOSPITAL ASSOCIATION, AND MANY HEALTH IMPROVEMENT ADVOCACY GROUPS FOR PARTICULAR TYPES OF CANCER. ALTHOUGH THE SIGNIFICANT COST OF STAFF TIME DEVOTED TO THESE ACTIVITIES IS NOT QUANTIFIED BY THE CENTER, THE INSTITUTION CONSIDERS THESE EFFORTS TO COLLABORATE AND BUILD COMMUNITY RESOURCES TO BE OF SIZEABLE COMMUNITY BENEFIT. IN FEBRUARY 2009 THE INSTITUTION'S COMMUNITY OUTREACH COMMITTEE - COMPOSED OF REPRESENTATIVES FROM MORE THAN TEN DEPARTMENTS WITHIN THE HOSPITAL AND SELECTED AFFILIATED COMMUNITY ORGANIZATIONS - SURVEYED 143 COMMUNITY ORGANIZATIONS REGARDING THEIR CANCER OUTREACH, EDUCATION, AND SUPPORT SERVICES NEEDS. THE RESULTS OF THE NEEDS ASSESSMENT SURVEY WERE INSTRUMENTAL IN IDENTIFYING LOCAL BARRIERS AND GAPS IN SERVICES AND OPPORTUNITIES FOR ADDITIONAL COMMUNITY PARTNERSHIPS. MSKCC STAFF MEMBERS CONTINUE TO ENGAGE WITH MANY OF THE ORGANIZATIONS WHO PARTICIPATED IN THE SURVEY TO FOSTER OR DEEPEN COLLABORATIVE EFFORTS AND TO INCREASE CAPACITY FOR CULTURALLY SENSITIVE CANCER PROGRAMMING AND SERVICES. EDUCATION, TRAINING AND RESEARCH EDUCATION AND TRAINING IS A KEY COMPONENT OF MEMORIAL SLOAN-KETTERING CANCER CENTER'S MISSION, AND AN IMPORTANT EXAMPLE OF HOW THE INSTITUTION MAKES CONTRIBUTIONS TO THE CARE AND TREATMENT OF CANCER PATIENTS FAR BEYOND ITS OWN WALLS THROUGH WORKFORCE DEVELOPMENT. OUR TRAINING, GRADUATE, AND CONTINUING EDUCATION PROGRAMS PREPARE PHYSICIANS, SCIENTISTS, NURSES, AND TECHNICIANS TO BE LEADERS IN THEIR CHOSEN FIELDS. THESE HEALTHCARE PROVIDERS CAN THEN TAKE THE EXPERTISE GAINED FROM WORKING WITH OUR SPECIALISTS TO OTHER HEALTHCARE INSTITUTIONS AROUND THE COUNTRY AND THROUGHOUT THE WORLD. MSKCC ALSO TRAINS GRADUATE STUDENTS AND POSTDOCTORAL RESEARCHERS WORKING IN MANY AREAS OF BASIC SCIENCE AND TRANSLATIONAL RESEARCH. WHEN THESE YOUNG SCIENTISTS COMPLETE THEIR TRAINING, THEY BRING THE SKILLS OBTAINED IN OUR LABORATORIES INTO THE ACADEMIC COMMUNITY AT LARGE AS WELL AS THE PRIVATE SECTOR. MSKCC SPONSORS SEVERAL PROGRAMS THAT GIVE MEDICAL STUDENTS, UNDERGRADUATES, AND HIGH SCHOOL STUDENTS THE OPPORTUNITY TO WORK AT THE INSTITUTION DOING CLINICAL AND LABORATORY RESEARCH. THROUGH THESE PROGRAMS MEMORIAL SLOAN-KETTERING CANCER CENTER STRIVES TO INCREASE THE PIPELINE OF SCIENTISTS AND PHYSICIANS WORKING IN ONCOLOGY. MSKCC'S OFFICE OF DIVERSITY PROGRAMS (ODP) IN CLINICAL CARE, RESEARCH, AND TRAINING PROVIDES FUNDING TO ENCOURAGE INTEREST IN PURSUING CAREERS IN THE FIELD OF ONCOLOGY FOR MEMBERS OF MINORITY GROUPS WHO ARE UNDERREPRESENTED IN MEDICINE AND WISH TO PARTICIPATE IN THE NATIONAL CANCER INSTITUTE'S MEDICAL STUDENTS' SUMMER FELLOWSHIP PROGRAM. THE ODP ALSO COORDINATES A SIX-WEEK SUMMER EXPOSURE PROGRAM TO EXPOSE UNDERREPRESENTED MINORITY HIGH SCHOOL STUDENTS TO CAREERS IN MEDICINE AND RESEARCH. MEMORIAL SLOAN-KETTERING CANCER CENTER UTILIZED $100 MILLION OF THE INSTITUTION'S RESOURCES DURING 2011 TO SUPPORT ITS EDUCATION AND TRAINING MISSION, WHICH WE SEE AS VITAL GIVEN OUR LEADERSHIP ROLE IN CANCER CARE TREATMENT AND RESEARCH.</Explanation>
