Desc	MEDICAL RESEARCH ORGANIZATION ACTIVITIES (A) THE HHMI INVESTIGATOR PROGRAM (B) JANELIA RESEARCH CAMPUS (A) The HHMI Investigator Program The Howard Hughes Medical Institute's approach to biomedical research can be summarized in three words: people, not projects. By employing scientists as HHMI investigators - rather than awarding research grants - the Institute provides long-term, flexible funding that enables its researchers to pursue their scientific interests wherever they lead. HHMI believes that scientists of exceptional talent and imagination will make fundamental discoveries of lasting scientific value and benefit to humanity if they are given the resources, time, and freedom to pursue challenging questions. The Institute nurtures the creativity and intellectual daring of scientists who are willing to set aside conventional wisdom or the "easy" question for a fundamental problem that may take many years to solve. Among the characteristics that distinguish this group of scientists are qualities such as creativity, a penchant for risk-taking, and a commitment to discovery, productivity, and perseverance. This unique research model is an imaginative and powerful alternative to funding biomedical research through grants. The HHMI Investigator Program employs more than 270 HHMI researchers, among them 15 Nobel laureates and more than 150 members of the National Academy of Sciences. HHMI investigators direct Institute research laboratories on the campuses of 59 universities and other research organizations throughout the United States. Since the early 1990s, investigators have been selected through rigorous national competitions. The Institute solicits applications directly from scientists at medical schools and other research institutions in the United States, with the aim of identifying those who have the potential to make significant contributions to science. HHMI employs an open application process to ensure that it is selecting its researchers from a broad and deep pool of scientific talent. (B) Janelia Research Campus HHMI's Janelia Research Campus in Ashburn, Virginia, helps open scientific fields by breaking through technical and intellectual barriers. At Janelia, integrated teams of lab scientists and tool-builders pursue a small number of scientific questions with potential for transformative impact. To drive science forward, methods, results, and tools are shared with the scientific community. In late 2017, Janelia moved to a 15-year research model. Under this new model, Janelia plans to develop a given research area for roughly 15 years to gain traction and attract outside interest, at which point it will cycle to a new area of focus. This approach enables Janelia to stay at the frontier of science, advancing 1-3 research areas at any point in time. Janelia's first 15-year research area is Mechanistic Cognitive Neuroscience. In October 2018, HHMI launched an open, international competition to identify an additional 15-year research focus to join the current research at Janelia. The new research area will be announced in Spring 2020. In February 2019, HHMI announced that Ron Vale, an HHMI investigator at the University of California, San Francisco, will be Janelia's next Executive Director. His appointment begins in February 2020. Vale succeeds Janelia's Founding Executive Director, Gerry Rubin, who will remain at Janelia to continue his scientific work. In the current fiscal year, there were 36 group leaders, five fellows, and 15 senior fellows at Janelia, in addition to graduate students, other scientific trainees, and visiting scientists. Janelia also operates a vibrant scientific conference program, bringing many scientists to its campus each year for educational meetings.	Desc

Desc	SUPPORT FOR INTERNATIONAL SCIENCE 4c: Support for International Science HHMI continues to support forty-one scientists from 16 countries who were selected in 2017 as International Research Scholars, exceptional early-career scientists poised to advance biomedical research across the globe. HHMI teamed up with the Bill & Melinda Gates Foundation, the Wellcome Trust, and the Calouste Gulbenkian Foundation to develop scientific talent around the world, and with these partners awarded a total of over $29.3 million to this group of scholars. Each researcher will receive a five-year award of $715,000, including indirect costs. The award is a major boost for scientists early in their careers, and offers the freedom to pursue new research directions and creative projects that could develop into top-notch scientific programs. Africa Health Research Institute in South Africa In 2009, HHMI helped launch the KwaZulu-Natal Research Institute for TB-HIV (K-RITH) in collaboration with the University of KwaZulu-Natal (UKZN), and has provided significant funding to support its research efforts. In 2016, in a move to improve the health of people locally and globally, K-RITH joined forces with the Africa Centre for Population Health to form a groundbreaking new interdisciplinary institute to fight tuberculosis (TB), HIV and related diseases. The new organization, the Africa Health Research Institute (AHRI), is located at the heart of South Africa's TB and HIV co-epidemic in KwaZulu-Natal Province. The effort brings together the Africa Centre's detailed population data from over 100,000 participants, with K-RITH's expertise in basic science and its world-class laboratory facilities. HHMI, together with the Wellcome Trust, continues to provide grant support to AHRI, with the University College London and UKZN serving as significant academic partners. AHRI is committed to working towards the elimination of HIV and TB. To achieve this, the institute will bring together leading researchers from different fields, use cutting-edge science to improve people's health, and will help to train the next generation of African scientists.

Schedule F, Part I, Line 2 Procedures for monitoring use of grant funds

During its 2019 fiscal year, HHMI continued to support International Research Scholars selected through one or more competitions open to all eligible applicants. The procedures described in this section are related to grants that were accrued in a previous fiscal year. Eligibility requirements included, but were not limited to, a full-time appointment at a nonprofit scientific research organization in a country other than the United States, and a research focus on basic biological processes or disease mechanisms. Qualified applicants were evaluated by a panel of scientific experts with final selections made by HHMI leadership. The disbursement of grant funds to support the work of International Early Career Scientists and Senior International Research Scholars is made in accordance with all applicable U.S. laws. Funds are paid to an institutional account. In order to monitor the activities and productivity of the grants, each scientist is required to submit an annual progress report concerning his or her research and each grantee institution is required to submit annual financial reports. These reports are reviewed by HHMI staff. site visits and audits are conducted if warranted and grantees attend scientific meetings of HHMI US-based scientists.

Form And Line Reference	Schedule I, Part I, Line 2 Procedures for monitoring use of grant funds.	FormAndLineReferenceDesc
Explanation	HHMI awards institutional grants in support of precollege, undergraduate, and graduate education in the US through periodic national competitions for which select institutions are eligible to apply. Each program sets out specific criteria and objectives, proposals are evaluated by a panel of experts with the final selection made by HHMI leadership. The Institute also awards fellowships to international predoctoral students, to medical students seeking to conduct basic laboratory research, and to doctoral students (the Gilliam Fellows). These grants are also awarded on a competitive basis. A small number of grants are awarded based on direct application to HHMI for specific initiatives directly related to science education. The disbursement of funds occurs principally through biomedical research institutions, universities, and colleges. HHMI grantees are required to file annual progress reports that detail expenditures in accordance with the terms of the grant, as well as full description of program activities undertaken with the funds. These are subject to careful review and analysis by HHMI staff with more detailed review by the Institute auditors as warranted. The Institute continues to assess reporting requirements to ensure the quality and timeliness of both financial and programmatic reports. In addition to site visits made by HHMI staff, program directors meet on a regular basis to discuss their activities and share information about best educational practices.	ExplanationTxt

Schedule J, Part I, Line 1a First-class or charter travel	Under HHMI policies, HHMI reimburses its Trustees for the reasonable cost of airfare one class above coach for domestic or international flights, and its President, Vice Presidents, and certain advisory group members for the reasonable cost of airfare at one class above coach for domestic or international flights of three hours or more. If a particular aircraft does not have a business class section, one class above coach may be first class. As an alternative, HHMI may reimburse for the cost of coach airfare plus the cost of an upgrade to travel at one level above coach for a flight of three hours or more. Such travel reimbursements are excluded from taxable compensation in accordance with HHMI's accountable plan. During fiscal year 2019, two officers, three trustees and one key employee flew first class.
Schedule J, Part I, Line 1a Tax indemnification and gross-up payments	Under HHMI's moving expense reimbursement policy, if an employee is relocating at HHMI's request, HHMI will ordinarily provide a tax gross-up for the reimbursable moving expenses that must be treated as taxable to the employee. HHMI continued to follow this standard practice during the 2019 fiscal year. During fiscal year 2019, one of the officers and one of the highest compensated employees received a tax gross-up.
Schedule J, Part I, Line 1a Housing allowance or residence for personal use	In fiscal year 2019, HHMI's President resides in an HHMI-owned house on the headquarters campus, for which she pays HHMI at a fair market rental rate. Because HHMI's President was also required to spend time at HHMI's Janelia campus, where she runs a research laboratory as well as attends meetings and participates in conferences, HHMI made an apartment available to her at that location. HHMI's Vice President and Executive Director, Janelia Research Campus, is required as a condition of employment to reside on the Janelia campus in housing built for that purpose. HHMI's Vice President and Chief Scientific Officer currently resides in an HHMI-owned apartment on the headquarters campus, for which he pays HHMI at a fair market rental rate. The Institute provides a housing assistance program for three individuals who relocated to take positions with HHMI, which may be used to cover such individuals' mortgage or rent payments. The housing assistance program is treated as additional taxable compensation.
Schedule J, Part I, Line 7 Non-fixed payments	HHMI has an incentive compensation plan for its senior investment staff under which a portion of their compensation is determined based on performance of HHMI's portfolio against market benchmarks. HHMI also makes one-time payments to some of its other employees, including but not limited to officers, in recognition of exceptional performance.
Schedule J, Part I, Line 8 Payments on contract that is subject to the initial contract exception	When recruiting individuals for high-level positions, HHMI typically enters into initial contracts. HHMI has entered into initial contracts with a number of Vice Presidents. HHMI's standard practice is to have independent compensation consultants regularly review and confirm the reasonableness of compensation of HHMI's officers and key employees, regardless of whether the initial contract exception applies.

Form 990, Part III, Line 4b Program Service Description	HHMI's Department of Science Education emphasizes initiatives with the power to transform graduate, undergraduate, and precollege education in the life sciences. During its 2019 fiscal year, the Institute distributed approximately $60 million in grants and fellowships to support science education. Through its Science Education initiatives, HHMI invests in individuals, institutions, initiatives, and media that advance learning. HHMI also nourishes the public understanding of science by bringing important stories of scientific discovery to a wide variety of audiences. (A) Science Education Grant and Research Programs HHMI's Inclusive Excellence initiative aims to help colleges and universities increase their capacity for inclusion in science of all students, especially those students who come to college via non-traditional pathways. These "new majority" students include persons from groups excluded because of their ethnicity or race, first-generation college students, students who transfer from community colleges, and working adults with families. In the spring of 2019, HHMI announced the third round of competition for the initiative, with the goal of adding up to 30 more schools to the program. The plan is to announce new awards in the spring of 2021. This third cohort of schools will join the current Inclusive Excellence community which is now 57 US colleges and universities. HHMI completed a pilot project with the University of Maryland, Baltimore County (UMBC), the Pennsylvania State University, and the University of North Carolina at Chapel Hill, in the collaborative Meyerhoff Adaptation Project. The pilot project aims to learn whether elements of UMBC's highly regarded Meyerhoff Scholars Program can be adapted and successfully implemented at other research universities. Building on what is being learned through the Meyerhoff Adaptation Project pilot, in 2019 HHMI announced a new initiative called Driving Change. Awards will be made to up to six US research universities beginning in 2021. Driving Change grantees will: (i) create and implement their version of UMBC's Meyerhoff Scholars Program; (ii) develop and implement activities aimed at creating a more inclusive STEM learning environment for all students; and (iii) actively participate in a learning community of Driving Change institutions. The HHMI Professors program empowers accomplished science faculty at leading research universities to apply the rigor and creativity that make them successful in research to important challenges in undergraduate science education. HHMI Professors model fundamental reform in the way undergraduate science is taught at research universities through innovative teaching and are encouraged to share ideas and collaborate with their peers to improve science education. In addition to their commitment to student learning, these highly visible scientists have developed new educational resources and implemented novel mentoring programs to support students. To date, 69 scientists have been named HHMI Professors, with the most recent cohort of 14 added in 2018. HHMI's Exceptional Research Opportunities Program (EXROP) encourages talented students who belong to groups excluded from science to pursue careers in science by placing selected undergraduates in summer research experiences in the labs of HHMI investigators, professors, and at the Janelia Research Campus. In 2019, a total of 29 students were EXROP Capstone participants, engaging in a second year of summer research. In 2019, the Science Education Alliance Phage Hunters Advancing Genomics and Evolutionary Science (SEA-PHAGES) added 18 institutions-17 colleges and universities in the US and one in Canada. SEA-PHAGES is a two-semester course-based research experience designed to replace the traditional introductory biology lab sequence in the undergraduate curriculum. Developed in 2008, the SEA-PHAGES program has been implemented at over 150 colleges and universities and has produced more than 100 publications, many including SEA-PHAGES students and faculty as co-authors. In the fall of 2018, more than 4,400 students, primarily college freshmen and sophomores, participated in the program. HHMI's Gilliam Fellowships for Advanced Study Program supports PhD students who plan to pursue careers in academic science and who are committed to advancing diversity and inclusion in science. In FY19, HHMI awarded 44 new fellowships, including to eight EXROP alumni. Each award provides an annual payment of $50,000, which includes the fellow's stipend, a research allowance for the fellow, an institutional allowance to offset tuition and fees, and an allowance to support diversity and inclusion activities on the fellow's campus. In 2019, HHMI continued support for 14 HHMI Medical Research Fellows in their second year of research. The Med Fellows program enables students to take a year off from professional school to conduct laboratory research, and some apply to continue their research for a second year. The goal of the program is to provide a training path for those students who may one day choose to work at the intersection of basic research and clinical medicine. In 2019, HHMI continued support for three laboratories that provide professional development to scientists. The three grantee institutions are the Cold Spring Harbor Laboratory on Long Island, New York, the Jackson Laboratory in Bar Harbor, Maine, and the Marine Biological Laboratory in Woods Hole, Massachusetts. Together, the three institutions provide important resources for the scientific community, annually engaging hundreds of scientists at different levels of professional development-graduate students, postdoctoral scientists, and faculty members-in advanced courses and workshops, mainly during the summer. In 2019, HHMI continued support of K-12 science education activities in Maryland and Virginia. These local grantee organizations include: the Audubon Naturalist Society, the Chesapeake Bay Foundation, Loudoun County (Virginia) Public Schools, Montgomery County (Maryland) Public Schools, and Prince George's (Maryland) Public Schools. HHMI funded programs include: nature-based learning activities for students, parents, teachers, and principals; research internships for high school students; science curriculum development; professional development for middle school and high school teachers; and resource centers that enable teachers to provide authentic laboratory experiences for their students. (B) Educational Media HHMI BioInteractive, a resource for general high school biology, AP/IB biology, and college-level introductory biology teachers, has been in existence for nearly two decades and receives 3 million visitors per year through its website. The Educational Media Group produces the science education resources for BioInteractive, including interactive multimedia materials, scientific animations, videos, in-class activities, as well as award-winning, broadcast-quality short films. The resources are then made available to educators online, through the BioInteractive.org website and YouTube channel, and at workshops and conventions. In July 2019, HHMI hosted approximately 60 high school and higher education educators for the third annual HHMI Educator Professional Development Conference. The four-day conference at HHMI headquarters focused on inclusive learning environments, BioInteractive's identity, values and approaches, and sharing teaching and professional development expertise among attendees. Featured speakers on inclusive teaching and educator professional development were Dr. Meghan Bathgate, Yale University, Dr. Bryan Dewsbury, University of Rhode Island, and Dr. Brooke (Bourdelat-Parks) Gorman, Tennessee Aquarium. In November 2019, BioInteractive invited educators to participate in a three-year professional development BioInteractive Ambassador Academy. Up to 30 educators will be selected to work with BioInteractive to spread inclusive and equitable science teaching practices. The Academy will be a research-based professional development pathway focused on building professional learning leadership capacity and will include workshops, coaching, professional networking, and opportunities to participate in and present at science education conferences. In June 2019 the Educational Media Group launched a redesigned BioInteractive website. Educators can now create a BioInteractive account that allows them to more easily create lesson plans with BioInteractive resources and share them with other educators. In 2019 the Educational Media Group also developed and released a multipart animation series exploring the process of photosynthesis and the structures that carry it out and two short classroom films on ecology: From Ants to Grizzlies: A General Rule for Saving Biodiversity and Serengeti: Nature's Living Laboratory.

Gray Fellows Program In June 2016, HHMI announced a new program to recruit and retain early-career scientists who are from gender, racial, ethnic, and other groups underrepresented in the life sciences, including those from disadvantaged backgrounds. Through an open competition, HHMI selects scientists early in their training to become Hanna Gray Fellows. Each fellow will receive funding for up to eight years, with mentoring and active involvement within the HHMI community. In this two-phase program, fellows will be supported from early postdoctoral training through several years of a tenure-track faculty position. Through the current fiscal year, HHMI has selected 45 fellows to support, and will invest a total of up to $50 million for their support over eight years. A fourth competition is currently underway, with plans to select an additional 15 fellows by spring 2020. (E) Faculty Scholars HHMI, together with the Simons Foundation and the Bill & Melinda Gates Foundation, continued to provide grant support to 67 Faculty Scholars during the current fiscal year, early-career scientists who have great potential to make unique contributions to their field. The scientists conduct research at 37 institutions across the United States. Through the Faculty Scholars Program, HHMI and its partner philanthropies will spend up to $71.1 million over five years to support the scientists selected to receive grants. The range of five-year grant award totals is $600,000-$1.8 million, including indirect costs. Faculty Scholars are required to devote at least 50 percent of their total effort to the direct conduct of research. (F) eLife - Open Access Journal HHMI, together with the Wellcome Trust and the Max Planck Society, continues to support a top tier scientific journal called eLife. The online journal follows an open access model and is directed by practicing scientists. eLife Sciences Publications, Ltd., is an independent non-profit entity governed by a separate board of directors. eLife began publishing research articles in late 2012 and is publishing articles online on a regular basis.
Form 990, Part VI, Line 11b Review of form 990 by governing body	The Howard Hughes Medical Institute's Form 990 is initially prepared by its Tax Compliance Department, in coordination with other HHMI departments as needed. The draft return is reviewed by senior management of HHMI and by attorneys in HHMI's Office of the General Counsel. Following these reviews and the resolution of any questions that have been raised, the draft return is reviewed by HHMI's outside tax preparer. Finally, a copy of the return is provided to the members of HHMI's Board of Trustees so that they have an opportunity to review and comment on the return before it is filed.
Form 990, Part VI, Line 12c Conflict of interest policy	In addition to HHMI's code of conduct, which addresses conflicts of interest and applies to all HHMI employees, officers, Trustees, and advisors, HHMI has specific conflict of interest policies for different categories of personnel. Under the HHMI policies that apply to Trustees, officers, and key employees, these individuals must disclose annually interests that could give rise to conflicts of interest, and must certify annually their compliance with the conflict of interest policy that applies to them. Annual disclosures and certifications are reviewed by HHMI's Office of the General Counsel, and by other HHMI managers as needed. The conflict of interest policy covering HHMI's Trustees also requires each Trustee to disclose to the other Trustees any actual or apparent conflict of interest with respect to a proposed HHMI transaction. If the other Trustees decide that there is only the appearance of a conflict of interest, and that it could not reasonably be considered to affect the independent, unbiased judgment of the disclosing Trustee with respect to the transaction at issue, no further action is required to address the apparent conflict. In all other cases, including all actual conflicts of interest, the disclosing Trustee is not permitted to participate in the deliberation or decision regarding the transaction under consideration, and must leave the room during the deliberation and vote. The conflict of interest policies covering HHMI's officers and key employees require each covered individual to obtain supervisory approval up to the level of HHMI's President before entering into an affiliation with or acquiring an interest of 1% or more in any entity that is or may become a recipient of HHMI funds. HHMI's President, in consultation with HHMI's General Counsel, may permit the affiliation or interest if it would not interfere with the covered individual's performance of his or her HHMI responsibilities, would not create the appearance of a conflict of interest, and would be consistent with sound business judgment. HHMI's President may set conditions on approval, for example that there be no remuneration to the covered individual. Proposed affiliations and interests of 1% or more of HHMI's President are subject to the approval of the Chairman of the Trustees.
Form 990, Part VI, Line 15a Process to establish compensation of top management official	THE COMPENSATION FOR HHMI'S PRESIDENT, OTHER OFFICERS, AND KEY EMPLOYEES IS SET USING THE FOLLOWING PROCEDURES: EVERY OTHER YEAR, THE AUDIT AND COMPENSATION COMMITTEE OF HHMI'S BOARD OF TRUSTEES ENGAGES ONE OR MORE INDEPENDENT COMPENSATION CONSULTANTS TO CONDUCT A STUDY OF COMPARABLE MARKET DATA. THE STUDY INCLUDES DATA FOR HHMI'S PRESIDENT, OTHER OFFICERS, AND KEY EMPLOYEES. THE INDEPENDENT COMPENSATION CONSULTANTS ALSO PROVIDE AN OPINION REGARDING THE REASONABLENESS OF THE COMPENSATION ARRANGEMENTS FOR THE POSITIONS INCLUDED IN THE STUDY. THE STUDY INCLUDES COMPARABLE MARKET DATA FOR ALL COMPONENTS OF COMPENSATION FOR EACH PERSON COVERED BY THE STUDY, INCLUDING BASE SALARY, INCENTIVE COMPENSATION (IF ANY), AND BENEFITS. THE BOARD OF TRUSTEES RELIES ON THE MARKET DATA AND OPINION PROVIDED BY THE COMPENSATION CONSULTANT IN MAKING COMPENSATION DECISIONS FOR HHMI'S PRESIDENT, OTHER OFFICERS AND KEY EMPLOYEES. THE DECISION IS MADE BY INDEPENDENT TRUSTEES. ANY TRUSTEE WHO HAS A CONFLICT OF INTEREST WITH RESPECT TO A SPECIFIC OFFICER OR KEY EMPLOYEE MUST RECUSE HIMSELF OR HERSELF FROM THE DECISION ON THAT PERSON'S COMPENSATION, AND LEAVE THE MEETING ROOM DURING THE DEBATE AND VOTING ON IT. IN THE ALTERNATE YEARS WHEN A STUDY IS NOT DONE, THE TRUSTEES CONFIRM WITH THE INDEPENDENT COMPENSATION CONSULTANTS THAT THE RANGE OF ANY PROPOSED MERIT INCREASES FOR HHMI EMPLOYEES, INCLUDING SENIOR MANAGEMENT, IS REASONABLE COMPARED WITH GENERALLY PREVAILING COMPENSATION INCREASES IN THE MARKET OVER THE PAST YEAR. THE BOARD OF TRUSTEES RELIES ON THIS ADVICE IN MAKING COMPENSATION DECISIONS FOR HHMI'S PRESIDENT, OTHER OFFICERS AND KEY EMPLOYEES. RECUSAL PROCEDURES ARE THE SAME AS IN THE YEARS WHEN A STUDY IS DONE. IN EACH YEAR, MINUTES OF THE DISCUSSIONS AND DECISIONS REGARDING COMPENSATION ARE PREPARED AFTER EACH MEETING AND ARE SUBMITTED FOR APPROVAL AT THE NEXT MEETING. APPROVED MINUTES ARE KEPT IN HHMI'S RECORDS. ALL MINUTES INCLUDE THE DATE OF THE MEETING, IDENTIFY THOSE TRUSTEES WHO ATTENDED AND VOTED ON THE COMPENSATION ARRANGEMENTS, AND NOTE ANY RECUSALS OF TRUSTEES WITH A CONFLICT OF INTEREST. THE COMPARABILITY STUDIES AND OPINIONS RELIED ON AT THE MEETING ARE REFERENCED IN THE MINUTES, AND COPIES OF THESE MATERIALS ARE ALSO KEPT IN HHMI'S RECORDS. HHMI'S BOARD OF TRUSTEES FOLLOWED THIS PROCESS IN AUGUST 2016 AND AUGUST 2017 IN DETERMINING COMPENSATION FOR THE FOLLOWING POSITIONS FOR FISCAL YEAR 2018: PRESIDENT, VICE PRESIDENTS, AND MANAGING DIRECTORS - INVESTMENTS.
