      <Description>THE JOURNAL OF IMMUNOLOGY - ONE OF THE MOST SIGNIFICANT WAYS THAT AAI PROVIDES EDUCATION ABOUT THE FIELD OF IMMUNOLOGY IS THROUGH ITS PUBLICATION OF THE JOURNAL OF IMMUNOLOGY ("THE JI"). THE JI, A SEMI-MONTHLY JOURNAL THAT PUBLISHES NOVEL RESULTS FROM ALL AREAS OF EXPERIMENTAL IMMUNOLOGY, IS THE LEADING SCHOLARLY JOURNAL IN THE FIELD OF IMMUNOLOGY. THIS JOURNAL IS PUBLISHED IN PRINT AND ELECTRONIC FORM AND DISTRIBUTED TO ALL AAI MEMBERS AND TO OTHER SUBSCRIBERS. ARCHIVES OF THE JI ARTICLES ARE ALSO AVAILABLE ONLINE TO THE PUBLIC 12 MONTHS AFTER THEIR INITIAL PUBLICATION AT WWW.JIMMUNOL.ORG. THE PUBLICATION OF THE JI EDUCATES AAI MEMBERS AND THE PUBLIC ABOUT THE LATEST DEVELOPMENTS IN THE FIELD OF IMMUNOLOGY. IT ALSO FOSTERS SCIENTIFIC DISCOURSE AMONG IMMUNOLOGISTS BY ESTABLISHING A FORUM FOR THE DISSEMINATION AND DISCUSSION OF CUTTING-EDGE RESEARCH IN IMMUNOLOGY. OVERSIGHT FOR THE ACTIVITIES AND POLICIES OF THE JI ARE CARRIED OUT BY AN EIGHT-MEMBER PUBLICATIONS COMMITTEE WHICH ALSO INCLUDES THE EXECUTIVE DIRECTOR WHO SERVES AS THE EXECUTIVE EDITOR OF THE JI.</Description>

        <Description>ANNUAL MEETING - EACH YEAR, AAI HOLDS AN ANNUAL MEETING WHICH DRAWS THOUSANDS OF ATTENDEES AND HUNDREDS OF EXHIBITORS. ATTENDEES INCLUDE BOTH AAI MEMBERS AND NON-MEMBERS WHO HAVE AN INTEREST IN IMMUNOLOGY. DURING THE ANNUAL MEETING, AAI OFFERS A VARIETY OF LECTURES, SEMINARS, AND SYMPOSIA ON SCIENTIFIC TOPICS RELATED TO THE FIELD OF IMMUNOLOGY, WHICH ARE AVAILABLE TO ALL ATTENDEES. MUCH OF THE CONTENT OF THE ANNUAL MEETING IS FOCUSED ON THE NEEDS AND INTERESTS OF STUDENTS AND TRAINEES IN IMMUNOLOGY. TRAINEES MAY ATTEND THE MEETING AT A SIGNIFICANTLY REDUCED COST, AND THEY ARE ENCOURAGED TO PURSUE SPEAKING OPPORTUNITIES AT THE MEETING AND TO ATTEND PROGRAMS AND SEMINARS GEARED TOWARDS IMMUNOLOGY STUDENTS AND EARLY CAREER IMMUNOLOGISTS. INCLUDED AMONG THE WORKSHOPS AT THE ANNUAL MEETING ARE PROGRAMS ON GRANT-WRITING, FUNDING OPPORTUNITIES FOR IMMUNOLOGISTS, CAREERS IN SCIENCE, AND PROFESSIONAL CIRCUMSTANCES AND CHALLENGES UNIQUE TO WOMEN AND UNDER-REPRESENTED MINORITIES IN SCIENCE AND ACADEMICS.AT THE ANNUAL MEETING, AAI ALSO SPONSORS A CAREER RESOURCE PROGRAM FOR ALL REGISTRANTS. THIS PROGRAM PROVIDES ATTENDEES THE OPPORTUNITY TO POST THEIR CVS, LEARN ABOUT JOB OPPORTUNITIES, AND ATTEND SEMINARS ON INTERVIEWING FOR JOBS AND PREPARING RESUMES.</Description>

        <Description>COMMITTEES AND MEMBER SERVICES - AN IMPORTANT FUNCTION OF AAI IS ITS INTERACTION WITH RELATED SCIENTIFIC ORGANIZATIONS, INSTITUTIONS, AND GOVERNMENT AGENCIES. IN ORDER TO PROMOTE THE KNOWLEDGE OF IMMUNOLOGY, AAI IS AFFILIATED WITH OTHER SCIENTIFIC ASSOCIATIONS AND PROVIDES ITS MEMBERS WITH CONCURRENT MEMBERSHIPS IN THE FEDERATION OF AMERICAN SOCIETIES FOR EXPERIMENTAL BIOLOGY ("FASEB") AND IN THE INTERNATIONAL UNION OF IMMUNOLOGICAL SOCIETIES ("IUIS"). AAI'S AFFILIATION WITH THESE OTHER SCIENTIFIC ASSOCIATIONS ALLOWS IT TO UTILIZE ALL SCIENTIFIC ADVANCEMENTS IN THE STUDY OF IMMUNOLOGY PRODUCED THROUGH DIFFERENT VENUES. THROUGH ITS ASSOCIATION WITH IUIS, AAI AND ITS MEMBERS PARTICIPATE IN INTERNATIONAL ISSUES CONFRONTING EDUCATION AND RESEARCH IN IMMUNOLOGY. AAI OFTEN NOMINATES ITS MEMBERS AND OTHER IMMUNOLOGISTS FOR GOVERNMENT AWARDS, ACTIVITIES, AND PANELS, INCLUDING PROGRAMS OF THE NATIONAL INSTITUTE FOR ALLERGY AND INFECTIOUS DISEASES ("NIAID"), THE AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE ("AAAS"), AND THE ASSOCIATION OF AMERICAN MEDICAL COLLEGES ("AAMC"). AAI ALSO KEEPS IN CLOSE CONTACT WITH UNIVERSITY DEPARTMENTS OF IMMUNOLOGY AND MOLECULAR BIOLOGY TO NOTIFY ITS MEMBERS AND THE PUBLIC ABOUT FELLOWSHIP, AWARD, TRAINING, AND JOB OPPORTUNITIES.</Description>

        <Explanation>ANNUALLY THE AAI COUNCIL, KEY EMPLOYEES, AND KEY COMMITTEE CHAIRMEN AND MEMBERS COMPLETE THE CONFLICT OF INTEREST STATEMENT WHICH IS AVAILABLE TO ALL COUNCIL MEMBERS AND THE EXECUTIVE DIRECTOR. IF A CONFLICT OR PERCEIVED CONFLICT ARISES, THE APPROPRIATE PERSON IS RECUSED FROM DELIBERATION AND VOTING, AND THE MINUTES OF THE MEETING ALSO REFLECT THAT ACTION.

        <ReturnReference>FORM 990, PART VI, SECTION B, LINE 15</ReturnReference>
        <Explanation>OFFICERS ARE NOT COMPENSATED FOR THEIR SERVICE AS COUNCILLORS OR OFFICERS. AAI MAINTAINS AN EMPLOYMENT CONTRACT WITH THE EXECUTIVE DIRECTOR AND ANNUALLY, AT ITS FALL MEETING, DETERMINES THE COMPENSATION OF THE EXECUTIVE DIRECTOR FOR THE SUBSEQUENT YEAR. THE DETERMINATION IS MADE AFTER REVIEW OF SEVERAL SALARY SURVEYS OF SIMILAR ORGANIZATIONS IN THE SAME GEOGRAPHIC AREA AND AN EVALUATION OF THE EXECUTIVE DIRECTOR'S PERFORMANCE. A MEMORANDUM FOR THE RECORD IS PREPARED SOON THEREAFTER DOCUMENTING THE PROCESS AND THE ACTION AND STATING THE INTENT TO ESTABLISH A REBUTTABLE PRESUMPTION OF REASONABLENESS. THE EXECUTIVE DIRECTOR ALSO RELIES ON SIMILAR SALARY SURVEYS AS WELL AS PERFORMANCE APPRAISALS WHEN DETERMINING THE COMPENSATION OF OTHER KEY EMPLOYEES. IN 2011 A COMPENSATION AND BENEFITS BENCHMARKING STUDY WAS PREPARED BY AN INDEPENDENT CONSULTING FIRM FOR THE AAI EXECUTIVE DIRECTOR POSITION. THE STUDY WAS PROVIDED TO THE AAI BOARD OF DIRECTORS PRIOR TO ITS REVIEW OF THE EXECUTIVE DIRECTOR'S COMPENSATION.</Explanation>

        <Explanation>FORM 990, PART XI, LINE 2C: AAI DOES NOT HAVE A SEPARATE COMMITTEE, OTHER THAN THE GOVERNING BODY, THAT PERFORMS THESE FUNCTIONS DUE TO THE SMALL SIZE OF THE BOARD OF DIRECTORS.
