It was founding Director Abraham Flexner’s belief that if the Institute “eschews the chase for the useful, the minds of its scholars will be liberated, they will be free to take advantage of surprises, and someday an unexpected discovery, apparently leading nowhere, will be found to be an indispensable link in a long and complex chain that may open new worlds in theory and practice.”

FROM THE DEVELOPMENT of programmable computers and the uncovering of the deep symmetries of nature to advances in societal understanding and historical ­practice, long and complex chains of knowledge have developed for nearly ninety years through research originating at the Institute for Advanced Study. Albert Einstein was one of the first in a continuous line of distinguished Institute ­scientists and scholars who have produced a deeper understanding of the physical world and of humanity. Yet the Institute’s remarkable history does not seem to weigh heavily on current­ ­scholars and scientists. Instead, the atmosphere focuses on the ­present, where every twist and hairpin bend changes our view. What do we know? What do we yet need to understand? How should we try to comprehend it? Work at the Institute takes place across historical studies, mathematics, natural sciences, and social science. Currently, a permanent Faculty each year award fellowships to some two hundred visiting Members, from about one hundred universities and research institutions throughout the world. The Institute’s reach has been multiplied many times over through the more than eight thousand Members who have influenced entire fields of study as well as the work and minds of colleagues and students. Thirty- three Nobel Laureates, forty-one of the fifty-six Fields Medalists, and sixteen of the eighteen Abel Prize Laureates, as well as many winners of the Wolf and MacArthur prizes, have been affiliated with the Institute. At the Institute, everything is designed to encourage scholars to take their research to the next level. This includes creating and sustaining an ­environment where Members live in an academic village of apartments, originally­ designed by Marcel Breuer in 1957, at the edge of the Institute’s eight hundred acres of campus, woodland, and farmland. Members eat in the same dining hall, share common rooms and libraries, and carry out their work in an institutional setting where human scale has been carefully maintained to

THOMAS CLARKE THOMAS encourage the sharing of ideas, mutual understanding, and friendship.

7 Each year a new intellectual mix is created by the Members, ranging from young postdoctoral fellows to distinguished senior professors, who typically stay a year but may stay up to five years and return for subsequent visits throughout their careers. A period spent as a Member is often a life-changing experience. Young scholars meet the contemporaries who, with them, will be leading figures in their field in the future. Senior Members have the time and freedom to initiate new lines of research. Freed from teaching and administration, Members are afforded opportunities for discussing their work with scholars and scientists from other fields. Here they are given the time to take advantage of serendipitous encounters at lunch, teatime, or at After Hours Conversations, an interdisciplinary program to encourage wide-ranging conversations in an informal environment. Throughout the year, the Institute hosts a broad array of concerts, lectures, and programs for the Institute community and the public. In addition, the Institute offers numerous and varied activities for Members, Visitors, and their families—from family science talks and children’s activities to play readings, jazz evenings, tennis lessons, and trips to museums and other cultural sites. Fundamental research at the Institute furthers our grasp of a world of diverse facts, structures, ideas, and cultures. This is due in large part to the precious freedom that Faculty and Members at the Institute experience— an independence enabled by the generosity of the Institute’s founders and subsequent benefactors. We share the conviction of our founders that such unrestricted deep thinking will change this world but where and how is always a surprise.

Three articles in the Spring 2017 Institute Letter were authored by Fadi Bardawil, Member in the School of Social Science; Thomas Dodman (top right), Member in the School of Historical Studies; Ian Jauslin, Member in the School of Mathematics; Pascal Marichalar, Visitor in the School of Social Science; Klaus Oschema, Gerda Henkel Stiftung Member in the School of Historical Studies; and Peter Redfield, Member in the School of Social Science. An exhibit (above) was curated by the History Working Group as a companion to the newsletter articles, and a booklet (right) was published. These materials appear at www.ias.edu/idea-tags/history-working-group.

The Usefulness of Useless Knowledge, published in early 2017 by Princeton University Press, features Institute for Advanced Study founding Director Abraham Flexner’s classic essay of the same title, first published in Harper’s magazine in 1939, alongside a new companion essay by current Director and Leon Levy Professor Robbert Dijkgraaf.

Angelos Chaniotis on A World of 367 Γ Emotions: The Making of an Exhibition Is there anything special about the ancient Greeks and their emotions? How could one avoid triviality in addressing this subject? Did the death of a beloved person not cause grief among the Greeks as in any other culture? Was economic inequality not the source of envy and hatred, a perceived danger the cause of fear, the birth of a child reason to rejoice, and disappointed love a source of sorrow? As far as we can see, the basic emotions that we know from our

20 Patrick J. O’Banion on Peace and Quiet in Castile To outsiders, the contentiousness, divisiveness, and downright un-neighborliness evident in the small Spanish town of Deza by the autumn of 1607 might well have seemed a tempest in a teapot. Those living in the newer Upper Neighborhood had been squaring off against the inhabitants of the older, medieval Lower Neighborhood for years, and the conflict appeared to be reaching a climax. Tensions had been building since the 1590s as recriminations, threats, public brawls, armed uprisings, and fiery sermons gave way to lawsuits and backroom political maneuvering that culminated in arrests, torture, murder, and exile.

Along with the life of Muhammad, the Qurʾān is a fundamental piece in Europe’s picture of Islam.

21 Von Neumann Fellow Lauren Williams, whose research explores connections at the interface of algebra, combinatorics, and physics, leads a Members’ seminar on the combinatorics of the amplituhedron in January. School of Mathematics

The School of Mathematics, established in 1933, was the first School at the Institute for Advanced Study. Several central themes in mathematics of the twentieth and twenty-first centuries owe their major impetus to discoveries that have taken place in the School, which today is an international center for research on mathematics and computer science.

During the academic year 2016–17, the School of Mathematics conducted a special program on homological mirror symmetry, which was FACULTY

led by Distinguished Visiting Professor Paul Seidel of the Massachusetts Jean Bourgain Institute of Technology. Homological mirror symmetry (HMS) started IBM von Neumann Professor with Maxim Kontsevich’s address at the International Congress of Helmut Hofer Mathematicians in 1994. By now, it is a mature area of mathematics in its Robert MacPherson own right but still one that can be approached from many different Hermann Weyl Professor directions, which interact fruitfully even when they remain formally (in Peter Sarnak the theorem-and-proof sense) independent. More concretely, there is a Thomas Spencer group of core conjectures that remain open in general even though many Richard Taylor Robert and Luisa Fernholz Professor special cases have been proved. These involve primarily symplectic Vladimir Voevodsky geometry, algebraic geometry, and homological algebra. At the same time, Avi Wigderson there is a lot of activity involving new formulations and interpretations of Herbert H. Maass Professor HMS, sometimes involving entirely different mathematical tools, as well as applications of its core ideas to new areas of mathematics. This open- PROFESSORS EMERITI endedness is part of the appeal of the subject. Enrico Bombieri The program was fortunate to be able to recruit participants with Pierre Deligne expertise in a broad selection of the relevant fields. There was a large group Phillip A. Griffiths working on the core conjectures of HMS and the structures that enter into Robert P. Langlands them (Fukaya categories, derived categories of coherent sheaves). Some very important emerging interactions with other fields, such as log algebraic geometry and non-Archimedean analytic geometry, were also very well represented. On the other hand, enumerative geometry in a more standard sense (Gromov-Witten theory or Donaldson-Thomas theory) had a lower profile in the program, at least compared to the role it has played in the development of mirror symmetry as a whole. At IAS and Princeton University, there are long-established research groups in symplectic geometry, string theory, algebraic geometry, and Heegaard Floer theory. The Simons collaboration in HMS has nodes in New York and Philadelphia. While there was a lot of informal interaction

Kepler went so far as to argue that God, in setting to the Peak of the Math up the natural world, could use pentagons but never heptagons, since the heptagon can’t be constructed with ruler and compass. Kepler’s World enthusiasm for geometry still resonates with modern mathematicians, At the age of 34, June Huh is at the even though we may not share his metaphysical certainties. Our views pinnacle of the math world. He is also differ in another important respect. For Kepler, the elements best known for his proof, with the of geometry, as set out by Euclid, were immutable (after all, they mathematicians Eric Katz and Karim constrained even God).

School of Natural Sciences

The School of Natural Sciences, established in 1966, supports research in broad areas of astrophysics, systems biology, and theoretical physics. Areas of current interest include investigating the origin and composition of the uni- verse; ­conducting research at the interface of molecular biology and the phys- ical ­sciences; and elementary particle physics, string theory, quantum theory, and quantum gravity.

Each year the School of Natural Sciences appoints about fifty Members, the majority of them postdoctoral fellows, who are typi- FACULTY

Areas of current Scott Tremaine interest in theoretical physics include elementary particle physics, string Richard Black Professor theory, quantum theory, and quantum gravity, and their relationship to Edward Witten Charles Simonyi Professor geometry, theoretical and observational astrophysics, and cosmology. Matias Zaldarriaga Research in the School’s astrophysics group encompasses astronomi- cal systems from nearby planets to distant galaxies, from black holes to PROFESSORS EMERITI the dark matter and dark energy that dominate the evolution of the universe. There is a growing cross-fertilization between astrophysics and Stephen L. Adler elementary particle physics, and the work of many Members and Faculty Freeman J. Dyson crosses the boundary between these two disciplines. Members in the Peter Goddard astrophysics research group employ an array of tools from theoretical Peter Goldreich physics, large-scale computer simulations, and ground- and space-based Arnold J. Levine observational studies to investigate the origin and composition of the universe, and to use the universe as a laboratory to study fundamental physics. At the Simons Center for Systems Biology, the tools of modern physics and mathematics are being applied to biological investigation, on varying scales, from ­molecular to organismic, and in some cases focusing on understanding disease processes. The School’s collaborative and pioneering approach to the sciences, which extends to the Institute’s School of Mathematics, Princeton University, and the larger scientific community, continues to transform research in these ANDREA KANE fields and to open opportunities for powerful and important discoveries.

33 Astrophysics NASA’s New Horizons spacecraft flew past Pluto on July 14, 2015, marking a major milestone in our exploration of the solar system: every known planet— leaving aside the question of whether Pluto should be called a planet— has now been visited, mapped, and measured by spacecraft. Of course, this remarkable accomplishment does not tell us whether additional planets remain to be discovered in the dark, cold outer reaches of the solar system beyond Pluto. Tantalizing hints that such planets might be present are provided by the discovery of a handful of bodies up to one thousand kilometers in size in orbits beyond Pluto, and by

41 Visiting Professor Bernard Harcourt gives the After Hours talk “Randomizing Justice,” which challenged actuarial methods that determine whom law enforcement officials target and punish. School of Social Science

Founded in 1973, the School of Social Science is devoted to a multidisciplinary and international approach to the analysis of societies, social change, and social problems. Every year, a theme is chosen to provide coherence to the collective work undertaken, although other areas of research are also welcome. In total, approximately twenty­-five scholars benefit from a membership in the School. For 2016–17, the theme was “Law and the Social Sciences.”

the interface between law and social inquiry has long been a domain of analysis explored by legal scholars and social scientists, but in FACULTY

recent decades, the emergence of contemporary critical legal thought, the Didier Fassin rise of New Legal Realism and Global Legal Pluralism, the renewed James D. Wolfensohn Professor interest in Islamic law and indigenous rights, and the debates regarding humanitarianism and human rights in international law have opened PROFESSORS EMERITI

avenues for novel approaches. In parallel, the work of law enforcement, the Joan Wallach Scott evolution of criminal justice, the phenomenon of mass incarceration, the Michael Walzer repression of undocumented immigrants, the adjudication of asylum seekers, the creation of international courts, the judicialization of political affairs, and the politicization of judicial decisions have led to an increasing production of empirical and theoretical research. It is this broad intersection between scientific inquiry and historical transformation, between new questioning and new problems, that has been collectively explored in the theme seminar led jointly by Didier Fassin, James D. Wolfensohn Professor, and Visiting Professor Bernard E. Harcourt, Isidor and Seville Sulzbacher Professor of Law and Political Science at Columbia University. What are the place, meaning, and functions of the law, its institutions, and its professionals in contemporary society? How have values, norms, and doctrines embedded in legal theories and practices changed over time, and what legacies do they leave? How do legal systems vary across cultures, and what sort of arrangements are made when they are con- fronted with one another? How are new technologies, such as DNA test- ing, or new knowledge, such as neuroscience, transforming legal practices? How do law and social sciences relate methodologically, and how are the legal disciplines responding to the dialogue with, and critique from, the social sciences and humanities? These are some of the questions that were addressed in 2016–17 from the multiple perspectives of law, penology,

53 OUTREACH IAS/PARK CITY MATHEMATICS INSTITUTE PHOTOS BY DAVID TITENSOR DAVID BY PHOTOS

The twenty-seventh annual PCMI Summer Session brought together researchers, college and university faculty, graduate and undergraduate students, and K–12 school teachers for a three-week experience comprising individual courses of study and meaningful interaction centered on the theme of random matrices.

The IAS/Park City Mathematics Institute (PCMI) is an intensive three-week summer program—held annually in Park City, Utah—that includes several parallel sets of activities for different groups across the entire mathematical community. Established in 1991 by a grant from the National Science Foundation, PCMI has been an outreach program of the Institute for Advanced Study since 1994. PCMI is currently funded by major grants from the National Science Foundation and Math for America, as well as grants from private foundations and individuals. The component programs of PCMI include a workshop for mathematics researchers, ten mini-courses for graduate students, two lecture series for undergraduate students, a program for faculty from predominantly undergraduate institutions, a faculty workshop on increasing minority participation in undergraduate mathematics, a teacher leadership program for K–12 school teachers, an international seminar on mathematics education, and a short course for high school students. Together these programs have over 340 participants. PCMI is a very successful effort toward vertical integration, with participants from different groups interacting with each other both scientifically and socially. The current PCMI director is Rafe Mazzeo (Stanford University). Each year, a different research theme is chosen, and a set of organizers who are specialists in the topic shape the program. The theme for 2017, “Random Matrices,” was organized by Alexei Borodin (Massachusetts Institute of Technology), Ivan Corwin (Columbia University), and Alice Guionnet (Centre National de la Recherche Scientifique–École Normale Supérieure de Lyon). Random matrix theory sits at the interface of many fields of mathematics and physics, and has practical applications in areas of computer science and statistics. The 2017 PCMI Summer Session brought together mathematicians working in many exciting areas of recent research in and around random matrix theory. The participants in the Undergraduate Summer School attended lecture series by Mihai Stoiciu (Williams College) and Antonio Auffinger (Northwestern University). In the Under- graduate Faculty Program, Victor Moll (Tulane University) led an exploration of the properties of special functions to give faculty participants the tools needed to work on research in special functions, both on their own and with their students. The Workshop on Increasing Minority Participation in Undergraduate Mathematics explored issues related to the experiences and participation of women and minority students in mathematics and sought to provide faculty participants with tools to increase the number of undergraduate mathematics majors from underrepresented groups. Two senior scholars were appointed by the Clay Mathematics Institute, and they interacted with participants in all of the PCMI programs: Craig Tracy (University of California, Davis) and Horng-Tzer Yau (Harvard University). The Teacher Leadership Program hosts sixty teachers from across the country who come together for a collaborative professional development experience in which they learn new mathematics, reflect on best pedagogical practices, and create new materials for their own and other classrooms. During the summer session, the participating teachers planned for a set of academic year outreach activities designed to extend the impact of this program, which include a series of weekend workshops to be held in eight sites around the country during the 2017–18 school year. The International Seminar “Mathematics Education Around the World: Bridging Policy and Practice” brought together participants from the Czech Republic, Guatemala, Nigeria, the Philippines, Spain, and the United States to engage in a dialogue on preparation of mathematics teachers in the area of probability and its role in the development of secondary mathematics curricula. The research theme for PCMI 2018 is “Harmonic Analysis,” organized by Carlos Kenig (University of Chicago), Fang-Hua Lin (NYU Courant Institute), Svitlana Mayboroda (University of Minnesota), and Tatiana Toro (University of Washington).

54 PROGRAM FOR WOMEN AND MATHEMATICS ALL PHOTOS ANDREA KANE ALL PHOTOS

The 2017 Women and Mathematics Program featured beginner and advanced workshops and lectures focused on geometry and randomness in group theory led by experts in mathematics from both American and international institutions. The group also participated in local activities, including the Princeton University 5K race, and educational outreach with Trenton’s UrbanPromise after-school program.

Originally founded by Karen Uhlenbeck and Chuu-Lian Terng, the twenty-fourth annual Women and Mathematics Program (WAM), “Gallteometry and Randomness in Group Theory,” was held at the Institute for Advanced Study May 15–26, 2017. Program activities were sponsored by the Institute, Princeton University, the National Science Foundation, and a grant from the Schwab Charitable Fund made possible by the generosity of Eric and Wendy Schmidt. The program organizers were Dusa McDuff (Barnard College), Christine Taylor and Sun-Yung Alice Chang (Princeton University), and Lisa Carbone (Rutgers University). Yen Duong (University of Illinois at Chicago), Gili Golan (Vanderbilt University), Funda Gultepe (University of Illinois at Urbana-Champaign), and Kasia Mankiewicz (McGill University) served as teaching assistants. Fourteen undergraduates, twenty graduate students, and six postdoctoral mathematicians from thirty universities attended the program. The program included lectures by Olga Kharlampovich (Hunter College), Goulnara Arzhantseva (University of Vienna), Kim Ruane (Tufts University), and Tatiana Nagnibeda (University of Geneva) on topics such as free and hyperbolic groups, random groups, non-positively curved groups, and amenability. Research seminars were led by Angelica Decibel (Brandeis University), Funda Gultepe, Rosemary Guzman, and Heejoung Kim (University of Illinois at Urbana-Champaign), Kasia Jankiewicz (McGill University), Sahana Hassan Balasubramanya (Vanderbilt University), Yuan Liu (University of Wisconsin– Madison), and Kathryn Lockwood (Case Western Reserve University). Colloquia were given by Lisa Carbone (Rutgers University) and Susan Hermiller (University of Nebraska–Lincoln). The Women-in-Science Seminar series comprised an evening chat on diversity and identity led by Yen Duong and Rosemary Guzman; a panel on mathematicians in academia moderated by Guzman and Evita Nestoridi (Princeton University), with Mirela Ciperiani (University of Texas at Austin), Ana Rita Pires (Fordham University), and Katrin Wehrheim (University of California, Berkeley); a panel on alternative careers for mathematicians with Sara Ellison (Massachusetts Institute of Technology), Margaret Holen (private investor), and Linda Ness (formerly at Applied Research); and a panel on work–life balance, moderated by Guzman and Katie McKeon (Rutgers University), with Maria Chudnovsky (Princeton University), Nancy Hingston (The College of New Jersey), Elizabeth Milicevic (Haverford College), Kim Ruane (Tufts University), and Lauren Williams (University of California, Berkeley). On May 22, participants visited the Princeton University mathematics department to hear talks by Princeton professors Evita Nestoridi on “Cut-Off for a Class of Hyperplane Arrangement Walks,” Adam Marcus on “Interlacing Polynomials and Ramanujan Graphs,” and Assaf Naor on “Embeddings of Groups, Poincaré Inequality, and Random Walks.” Susan Hermiller (University of Nebraska–Lincoln) led a workshop, “Computations with Finitely Presented Groups with GAP,” in a computer lab of the Lewis Library. Participants also engaged in two outreach events. On May 21, fifteen participants ran in a Princeton community 5K race. Immediately after the race, WAM volunteers taught local high school runners some probability of non-transitive Grime dice and the seventeen symmetry wallpaper patterns on a plane. On May 23, ten program participants visited UrbanPromise, Trenton’s after-school program at Trinity Episcopal Cathedral, to demonstrate math activities: how to cut Möbius valentines and how to fold and cut a five-pointed star with one cut à la Betsy Ross. WAM also purchased a strategy game called Otrio for the students. Thanks to a generous grant from Lisa Simonyi, the IAS Women and Mathematics Program is implementing a new Ambassador Program to build support and outreach networks across the country, thus making the annual May WAM program a springboard to energize a wide-ranging outreach program. The Ambassador Program will fund annually up to three postdoctoral or advanced graduate ambassadorships and up to six graduate ambassadors.

55 PROSPECTS IN THEORETICAL PHYSICS

Prospects in Theoretical Physics (PiTP) is an intensive two-week summer program geared specifically to graduate students and postdoctoral scholars considering a career in theoretical physics or astrophysics. First held at the Institute in 2002, Prospects in Theoretical Physics has, in past years, covered topics ranging from cosmology to the Large Hadron Collider (LHC), to string theory, to computation and biology, to insights into quantum matter, to computational plasma astrophysics. The program builds upon the strong relationship between the research groups at the Institute and Princeton University. Representatives from both institutions are among the program’s organizers and lecturers. PiTP encourages the participation of women, minorities, and students from smaller institutions that do not have extensive programs in theoretical physics or astrophysics. PiTP 2017 was held July 17–28 on the campus of the DAN KOMODA DAN Institute for Advanced Study. The theme of the 2017 program was “Particle Physics at the LHC and Beyond.” The program topics included: theoretical physics beyond the Standard Model, the status of naturalness and new approaches to fine-tuning problems, LHC Run II updates and projections, new table-top/low-energy probes of fundamental physics, high-intensity, low-energy collider experiments, CP violation and the strong CP problem, the next decade of dark matter, the next decade of CMB/ large-scale structure, future accelerators, and neutrino physics. The program was organized as a workshop, with ninety-minute lectures and active student participation in the afternoon, including discussion sessions. Roughly 120 participants from sixteen countries were officially enrolled in the program, with a majority of the visiting students living in the Princeton University dorms during the two-week program. Moreover, the program

56 SCIENCE INITIATIVE GROUP

Active since 1999 as an IAS outreach program supporting scientific research in the developing world, the Science Initiative Group (SIG) effectively put itself out of business in 2017 by successfully transferring ownership of the last of its projects to the home continent of its beneficiaries. The Regional Initiative in Science and Education (RISE), a program supporting African scientists pursuing advanced degrees in sub-Saharan Africa through five university-based thematic networks, was SIG’s primary focus from 2008 through 2016. With major funding from Carnegie Corporation of New York, RISE produced 94 doctoral and 91 master’s graduates and supported several postdoctoral researchers. Benefits accrued not only to the scientists themselves, but also to the eighteen universities and research institutes that made up the networks, to the institutions where graduates took up academic posts and/or consulting responsibilities, and to the many students and advisees of the graduates. A 2017 visit by SIG staff to the Federal University of Technology- Akure (FUTA) in Nigeria, one of six institutions comprising the African Materials Science and Engineering Network (AMSEN), provided a compelling snapshot of the impact RISE has had on the development of science and engineering leadership and expertise in sub-Saharan Africa. Seven AMSEN graduates—including two women—who earned doctorates from the University of the Witwatersrand in South Africa or from FUTA are now faculty members at FUTA, where a true community of scholars has formed. RISE also played a role in promoting gender balance, most strikingly within the historically male-dominated field of materials science. When AMSEN started in 2008, its constituent universities admitted a total of nine men and one woman as doctoral students, and all seven of its master’s students were men. As of the end of 2016, 36 men and 10 women had earned advanced degrees through AMSEN or were on track to complete them. More significantly, the success of the female graduates has encour- aged more women to pursue materials science at the RISE universities. The first woman to join AMSEN in pursuit of her doctorate, Adenike Olaseinde, credits her experience in the network for having given her the confidence to succeed in building a materials engineering career: “RISE has made me a better researcher. It supported me not only to do my Ph.D., but also to develop my own research group and labora- tory. Being part of this network has given me the confidence to lead.” In addition to her role as a Senior Lecturer at FUTA, Dr. Olaseinde created and leads the Advanced Materials and Electrochemical Research Group, and she has spearheaded new collaborations with partners including the University of Botswana, Pennsylvania State University, and the South African National Research Foundation’s iThemba Laboratory for Accelerator-Based Sciences. As RISE graduates use the skills and connections acquired through their networks to pursue academic and research careers, a legacy program will continue where RISE left off. The Nairobi-based African Academy of Sciences, through its Alliance for Accelerating Excellence in Science

(AESA) funding platform, has established the AESA-RISE Postdoctoral GROUP SCIENCE INITIATIVE ALL PHOTOS Fellowship Program. Supported by Carnegie Corporation, and initially Through the Regional Initiative in Science and Education, open only to RISE doctoral degree recipients, the program aims to foster a founded by SIG in 2008, more than 120 advanced degrees have been awarded to students from 18 African countries. culture of advanced research at African universities, building on the RISE Above: Dr. Adenike Olaseinde (in yellow) and colleagues at collaborative model and involving partners both within Africa and beyond.

57 SUMMER PROGRAM IN SOCIAL SCIENCE ANDREA KANE Led by Professor Didier Fassin, the 2015–17 Summer Program in Social Science convened nineteen early-career social scientists from Africa, the Middle East, and Latin America over a three-year cycle, with the first year at the Institute (right), the second year at the École des Hautes Études en Sciences Sociales, Paris, and the third year at the Swedish Collegium for Advanced Study in Uppsala (left). The Summer Program in Social Science was created in 2015 as an international and interdisciplinary initiative for early-career scholars from the “Global South,” in order to remedy the underrepresentation of Members from this part of the world in the regular program of the School of Social Science. Designed to draw together twenty social scientists from Africa, the Middle East, and Latin America, it aims to enrich and expand the realm of the social sciences through the confrontation of different intellectual traditions and perspectives; to facilitate and enhance the dialogue between various scientific disciplines and communities; and to strengthen international networks across continents. The program is multi-year so as to establish and consolidate links between the fellows and with the Institute. The first cycle spanned over three years in three different institu- tions: the Institute for Advanced Study in 2015, the Paris École des Hautes Études en Sciences Sociales in 2016, and the Uppsala Swedish Collegium for Advanced Study in 2017. During the program, the scholars pursued their own research projects. At an initial stage, each scholar presented his or her project and had it discussed in the perspective of publications in international journals. Thus, a conversation developed between a literary scholar from Palestine interested in the reception of Ibn Rushd’s commentary on Aristotle, an anthropolo- gist from Iraq examining the experience of exiles fleeing the war, an economist from the Ivory Coast assessing the impact of microfinance projects, a sociologist from Benin investigating gas smuggling across the border, a political scientist from Brazil analyzing clientelism in local elections, and a legal scholar from Chile studying anti-discrimination laws. This intellectual encounter led to a second level of reflection on the circulation, appropriation, and contestation of knowledge across different worlds and disciplines, which involves asymmetric power relations as well as potential mutual enrichment. Such experiences in the practice of the social sciences are common to many scholars, be they a Mexican sociologist, an Argentinian geographer, an Iranian anthropologist, or a South African historian. They became the matter of a collective project and of a forthcoming volume provisionally titled “The Politics of Global Knowledge.” After the success of the first cycle, supported by the Riks- bankens Jubileumsfund, the Wolfensohn Family Foundation, and the three participating institutions in Princeton, Paris, and Uppsala, the Mellon Foundation decided to fund three new cycles, which will be slightly different in their conception. Indeed, they will be two-year programs, with the first year at the Institute and the second in Bogotá at the Universidad Nacional de Colom-

bia and Johannesburg at the University of the Witwatersrand. ANDREA KANE There will therefore be a more direct involvement of academic Environmental conflicts in Buenos Aires, income inequality in Egypt, institutions and communities from the “Global South,” but the water shortage in rural Iran, debates over the age of sexual consent general goals of the program will remain similar: on the one hand, under South African law, and negotiations at the World Trade Organization—among other themes—were explored by participants offering scholars a stimulating scientific environment for their in the inaugural Summer Program in Social Science.

ACKNOWLEDGMENTS ( for the year ended June 30, 2017)

Each year researchers from around the world come to the Institute for Advanced Study to interact, explore, take risks, share, build, and discover. This would not be possible but for the far-sighted vision and support of a worldwide network of philanthropists. We thank our donors for their contributions in fiscal year 2016–17 during which new commitments to endowment and the IAS Fund totaled more than $25 million.

Gifts to Endowment The Institute for Advanced Study’s endowment started with a gift from our founders in 1930. It is the cornerstone of our academic independence, which is essential to our mission of long-term, foundational, curiosity-driven research. We are grateful to those who, following our founders’ example, invest in the future of the Institute.

Institute for Advanced Study— Louis Bamberger and Mrs. Felix Fuld Foundation

Financial Statements June 30, 2017 and 2016 (With Independent Auditors’ Report Thereon)

95 Independent Auditors’ Report

The Board of Trustees Institute for Advanced Study–Louis Bamberger and Mrs. Felix Fuld Foundation:

We have audited the accompanying financial statements of Institute for Advanced Study–Louis Bamberger and Mrs. Felix Fuld Foundation (the Institute), which comprise the statements of financial position as of June 30, 2017 and 2016, and the related statements of activities and cash flows for the years then ended, and the related notes to the financial statements. Management’s Responsibility for the Financial Statements Management is responsible for the preparation and fair presentation of these financial statements in accordance with U.S. generally accepted accounting principles; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free from material misstatement, whether due to fraud or error. Auditors’ Responsibility Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free from material misstatement. An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the auditors’ judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion. Opinion In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Institute for Advanced Study–Louis Bamberger and Mrs. Felix Fuld Foundation as of June 30, 2017 and 2016, and the changes in its net assets and its cash flows for the years then ended, in accordance with U.S. generally accepted accounting principles.

100 NOTES TO FINANCIAL STATEMENTS JUNE 30, 2017 AND 2016

(1) Organization and Summary of Significant Accounting Policies

Organization The Institute for Advanced Study—Louis Bamberger and Mrs. Felix Fuld Foundation (the Institute), an independent, private institution devoted to the encouragement, support, and patronage of learning, was founded in 1930 as a community of scholars where intellectual inquiry could be carried out in the most favorable circumstances. Focused on mathematics and classical studies at the outset, the Institute today consists of the School of Historical Studies, the School of Mathematics, the School of Natural Sciences, and the School of Social Science. Each school has a small permanent faculty, and some 190 fellowships are awarded annually to members visiting the Institute from other research institutions and universities throughout the world. The Founders’ original letter to the first Trustees described the objectives of the Institute as follows: “The primary purpose is the pursuit of advanced learning and exploration in fields of pure science and high scholarship to the utmost degree that the facilities of the institution and the ability of the faculty and students will permit.”

Summary of Significant Accounting Policies Basis of Presentation The accompanying financial statements, which are presented on the accrual basis of accounting, have been prepared to focus on the Institute as a whole and to present net assets and revenues, expenses, gains, and losses based on the existence or absence of donor-imposed restrictions. Accordingly, net assets and changes therein are classified as follows: • Permanently restricted net assets—net assets subject to donor-imposed stipulations that they be maintained permanently by the Institute. Generally, the donors of these assets permit the Institute to use all or part of the income earned on related investments for general or specific purposes. • Temporarily restricted net assets—net assets subject to donor-imposed stipulations that will be met by actions of the Institute and/or by the passage of time. • Unrestricted net assets—net assets not subject to donor-imposed stipulations. Unrestricted net assets may be designated for specific purposes by action of the Board of Trustees. Revenues are reported as increases in unrestricted net assets unless use of the related asset is limited by donor-imposed restrictions. Expenses are reported as decreases in unrestricted net assets. Expiration of donor-imposed stipulations that simultaneously increase unrestricted net assets and decrease temporarily restricted net assets are reported as net assets released from restrictions.

(a) Contributions and Grants Contributions and grants, including unconditional promises to give, are recognized initially at fair value as revenues in the period received. Conditional promises to give are not recognized until they become unconditional, that is when the conditions on which they depend are substantially met. Contributions of assets other than cash are recorded at their estimated fair value. Pledges of contributions to be received after one year are discounted at a risk-adjusted discount rate. The discount rates range from 0.28% to 1.89%. Amortization of discount is recorded as additional contribution revenue in accordance with donor-imposed restrictions, if any, on the contributions. The inputs to the fair value estimate are considered Level 3 in the fair value hierarchy. Contributions of long-lived assets are reported as unrestricted revenue. Contributions restricted for the acquisition of grounds, buildings, and equipment are reported as temporarily restricted revenues. These contributions are reclassified to unrestricted net assets upon acquisition of the assets.

(b) Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand and all highly liquid investments with an original maturity of three months or less, except for those managed as a component of the Institute’s investment portfolio.

101 (c) Mortgages receivable The Institute regularly offers first mortgages on primary residences to full-time faculty and senior administrative employees who have met certain requirements stipulated by the Board of Trustees.

(d) Investments Investments in marketable securities are reported in the financial statements at fair value based on published market quotations. Investments in limited partnerships and hedge funds are reported in the financial statements at estimated fair value using net asset value (NAV) or its equivalent as a practical expedient, based upon values provided by external investment managers or general partners, unless it is probable that all or a portion of the investment will be sold for an amount different from NAV. The Institute reviews and evaluates the values provided by external investment managers and general partners and agrees with the valuation methods and assumptions used in determining the fair value of funds. These estimated fair values may differ significantly from the values that would have been used had a ready market for these securities existed. As of June 30, 2017 and 2016, the Institute had no plans or intentions to sell investments at amounts different from NAV. The statements of activities recognize unrealized gains and losses on investments as increases and decreases, respec- tively, in unrestricted net assets unless their use is temporarily or permanently restricted by explicit donor stipulation or law. Gains and losses on the sale of investment securities are calculated using the specific identification method.

(e) Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The three levels of inputs used to measure fair value are as follows: • Level 1: Quoted prices in active markets for identical assets or liabilities. • Level 2: Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the asset or liabilities. Fair value estimates are made at a specific point in time, based on available market information and judgments about the financial asset, including estimates of timing, amount of expected future cash flows, and the credit standing of the issuer. In some cases, the fair value estimates cannot be substantiated by comparison to independent markets. In addition, the disclosed fair value may not be realized in the immediate settlement of the financial asset and does not reflect any premium or discount that could result from offering for sale at one time an entire holding of a particular financial asset. Potential taxes and other expenses that would be incurred in an actual sale or settlement are not reflected in amounts disclosed. Net Asset Value (NAV) is used as a practical expedient for certain commingled funds, privately held investments, and securities held in partnership format for which a readily determinable fair value is not available, unless the Institute believes such NAV calculation is not measured in accordance with fair value. These values may differ significantly from values that would have been used had a readily available market existed for such investments, and that difference could be material to the change in net assets of the Institute.

(f) Plant Assets and Depreciation Proceeds from the sale of plant assets, if unrestricted, are transferred to operating funds, or, if restricted, to amounts temporarily restricted for plant acquisitions. Depreciation is provided over the estimated useful lives of the respective assets on a straight-line basis (buildings and capital improvements 20-40 years, equipment 3-6 years).

(g) Deferred Revenue Amounts received on conditional grants are recorded initially as deferred revenue and are reported as revenues when expended in accordance with the terms of the condition.

102 (h) Split-Interest Agreements The Institute is the beneficiary of various unitrusts, a pooled income fund, and a gift annuity fund. The Institute’s interest in these split-interest agreements is reported as a contribution in the year received and is calculated as the difference between the fair value of the assets contributed to the Institute and the estimated liability to the benefi- ciary. This liability is computed using actuarially determined rates and is adjusted annually to reflect changes in the life expectancy of the donor or annuitant, amortization of the discount, and other changes in the estimates of future payments. The assets held by the Institute under these arrangements are recorded at fair value as determined by quoted market prices and are included as a component of investments.

(i) Unamortized Debt Issuance Costs Debt issuance costs represent costs incurred in connection with debt financing. Amortization of these costs is provided on the effective interest method extending over the remaining term of the applicable indebtedness. Debt issuance costs at June 30, 2017 and 2016 were net of accumulated amortization of $621,928 and $680,337, respectively. In fiscal year 2017, the Institute adopted the provisions of Accounting Standards Update (ASU) No. 2015-03, Simplifying the Presentation of Debt Issuance Costs, which requires that debt issuance costs related to the recognized debt liability be presented as a direct reduction from the debt liability on the statement of financial position. As a result of the adoption, the Institute reclassified the amount reported as unamortized debt issuance costs, net of $680,337 to long-term debt, net in the statement of financial position for the year ended June 30, 2016.

(j) Asset Retirement Obligation The Institute recognizes the fair value of a liability for legal obligations associated with asset retirements in the period in which the obligation is incurred, if a reasonable estimate of the fair value of the obligation can be made. When the liability is initially recorded, the Institute capitalizes the cost of the asset retirement obligation by increasing the carrying amount of the related long-lived asset. The liability is accreted to its present value each period and the capitalized cost associated with the retirement obligation is depreciated over the useful life of the related asset. Upon settlement of the obligation, any difference between the cost to settle the asset retirement obligation and the liability recorded is recognized as a gain or loss in the statements of activities.

(k) Fund Raising Expenses Fund raising expenses incurred by the Institute amounted to $1,660,098 and $1,974,810 for the years ended June 30, 2017 and 2016, respectively. This amount is included in administration and general expenses in the accompanying statements of activities.

(l) Functional Allocation of Expenses The costs of providing program services and support services of the Institute have been summarized on a functional basis in the statements of activities. Accordingly, certain operating costs have been allocated among the functional categories.

(m) Tax Status The Institute is exempt from federal income taxes pursuant to Section 501(c)(3) of the Internal Revenue Code (the Code) and is listed in the Internal Revenue Service Publication 78. The Institute has been classified as a public charity under Section 509(a) of the Code. There are certain transactions that could be deemed unrelated business income and would result in a tax liability. Management reviews transactions to estimate potential tax liabilities using a threshold of more likely than not. It is management’s estimation that there are no material tax liabilities that need to be recorded.

(n) Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Estimates also affect the reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates.

(o) Reclassification Certain prior year amounts have been reclassified to confirm with the current year’s presentation.

103 (2) Contributions Receivable Unconditional promises to give at June 30, 2017 and 2016 were as follows:

______2017 ______2016 Unconditional promises to give: Less than one year $ 3,859,280 8,116,086 One to five years ______8,670,212 ______12,611,800 12,529,492 20,727,886 Discount on promises to give (851,505) (822,484) ______Total $ 11,677,987 19,905,402 ______

At June 30, 2017 and 2016, 92% and 92% of gross contributions receivable and 10% and 34% of contributions revenue are from four donors, respectively. During fiscal 2011, the Institute received two conditional pledges totaling $100 million to enhance the Institute’s endowment fund. The pledges were conditioned on the Institute raising an additional $100 million in cash or pledges from third-party donors in the period January 1, 2011 through June 30, 2015, which have been met. The conditional pledge payments began in June 2011 and will continue through June 30, 2022. As of June 30, 2017 and 2016, the Institute has recorded revenue totaling approximately $93.8 million and $90.4 million, respectively, relating to these conditional pledges.

(3) Investments, Funds Held by Bond Trustee, and Beneficial Interest in Remainder Trust (a) Overall Investment Objective The overall investment objective of the Institute is to invest its assets in a prudent manner that will achieve a long- term rate of return sufficient to fund a portion of its annual operating activities and capital preservation. The Institute diversifies its investments among various managers and investment opportunities. Substantially all of the investments are pooled with each individual fund subscribing to or disposing of units on the basis of the market value per unit, determined on a quarterly basis. Major investment decisions are authorized by the Board’s Investment Committee, which oversees the Institute’s investment program in accordance with established guidelines.

(b) Allocation of Investment Strategies In addition to traditional stocks and fixed-income securities, the Institute may also hold shares or units in traditional institutional funds as well as in alternative investment funds involving hedged strategies, private equity, and real asset strategies. Hedged strategies involve funds whose managers have the authority to invest in various asset classes at their discretion, including the ability to invest long and short. Funds with hedged strategies generally hold securities or other financial instruments for which a ready market exists and may include stocks, bonds, put or call options, swaps, currency hedges, and other instruments, and are valued accordingly. Private equity funds employ buyout and venture capital strategies and focus on investments in turn-around situations. Real asset funds generally hold interests in public real estate investment trusts (REITS) or commercial real estate through sole-member entities. Private equity and real asset strategies therefore often require the estimation of fair values by the fund managers in the absence of readily determinable market values. Because of the inherent uncertainties of valuation, these estimated fair values may differ significantly from values that would have been used had a ready market existed, and the differences could be material. Such valuations are determined by fund managers and generally consider variables such as operating results, comparable earnings multiples, projected cash flows, recent sales prices, and other pertinent information, and may reflect discounts for the illiquid nature of certain investments held.

104 The following tables summarize the Institute’s investments and other assets at fair value by major category in the fair value hierarchy as of June 30, 2017 and 2016, as well as related strategy, liquidity, and funding commitments:

The Institute’s accounting policy is to recognize transfers between levels of the fair value hierarchy on the date of the event or change in circumstances that caused the transfer. There were no transfers between investments classified as Level 1 and Level 2 for the years ended June 30, 2017 or 2016. There were no transfers in or out of investments classified as Level 3 for the years ended June 30, 2017 or 2016. Private equity and venture capital investments are generally made through limited partnerships. Under the terms of such agreements, the Institute may be required to provide additional funding when capital or liquidity calls are made by fund managers. These partnerships have a limited existence, and they may provide for annual extensions for the purpose of disposing portfolio positions and returning capital to investors. However, depending on market conditions, the inability to execute the fund’s strategy, or other factors, a manager may extend the terms of a fund beyond its originally anticipated existence or may wind the fund down prematurely. The Institute cannot anticipate such changes because they generally arise from unforeseeable events, but should they occur they could reduce liquidity or originally anticipated investment returns. Accordingly, the timing and amount of future capital or liquidity calls in any particular future year are uncertain. As of June 30, 2017, the Institute is obligated under certain limited partnership agreements to advance additional funding in the amount of $94,121,839, which is anticipated to be called over the next 10 years.

107 Investment liquidity as of June 30, 2017 is aggregated below based on redemption or sale period:

(d) Redemption Restrictions—Hedge Funds At June 30, 2017, the Institute had hedge fund investments of approximately $551,237,900, of which approximately $57,769,100 was restricted from redemption for lock-up periods. At June 30, 2016, the Institute had hedge fund investments of approximately $543,974,400, of which approximately $43,631,900 was restricted from redemption for lock-up periods. Some of the investments with redemption restrictions allow early redemption for specified fees. The terms and conditions upon which an investor may redeem an investment vary, usually with the majority requiring 30 to 180 days’ notice after the initial lock-up period. The expirations of redemption lock-up periods are summarized in the table below:

Some of the investments with redemption restrictions allow early redemption for specified fees. The terms and conditions upon which an investor may redeem an investment vary, usually with the majority requiring 30 to 180 days’ notice after the initial lock-up period.

The expirations of redemption lock-up periods are summarized in the table below:

108 (4) Investment Return and Endowment Spending Policy Investment return consists of interest, dividends, and realized and unrealized gains and losses on investments. Each year, the Institute includes a portion of its endowment return in its operating budget, with the amount of such planned support determined using its spending policy. The policy of the Institute is to distribute for current spending a percentage of the fair value of pooled investments which is determined by the Board of Trustees annually. The spending rate for operating and capital purposes was 6.06% and 6.11% for 2017 and 2016, respectively. The following tables summarize the investment return and its classification in the statements of activities for the years ended June 30, 2017 and 2016: 2017 ______Temporarily Unrestricted restricted Total ______Dividends and interest, net of investment expenses $ (1,342,054) (1,949,063) (3,291,117) Net appreciation on investments 24,721,569 28,879,238 53,600,807 ______Total investment return 23,379,515 26,930,175 50,309,690 ______

Total investment management and advisory fees were $3,359,045 and $3,185,474 for the years ended June 30, 2017 and 2016, respectively.

(5) Endowment The Institute’s endowment consists of approximately 120 individual funds established for a variety of purposes including both donor-restricted endowment funds and funds designated by the Board of Trustees to function as endowments. Net assets associated with endowments, including funds designated by the Board of Trustees to function as endowments, are classified and reported based on the existence or absence of donor-imposed restrictions.

(a) Interpretation of Relevant Law The Institute has interpreted the New Jersey-enacted version of the Uniform Prudent Management of Institutional Funds Act (UPMIFA) as allowing the Institute to appropriate for expenditure or accumulate so much of a donor- restricted endowment fund as the Institute determines is prudent for the uses, benefits, purposes, and duration for which the endowment fund is established, subject to the intent of the donor as expressed in the gift instrument. Unless stated otherwise in the gift instrument, the assets in a donor-restricted endowment fund are donor-restricted assets until appropriated for expenditure by the Board of Trustees of the Institute. As a result of applicable accounting guidance, the Institute classifies as permanently restricted net assets (a) the original value of gifts donated to the permanent endowment, (b) the original value of subsequent gifts to the permanent endowment, and (c) accumula- tions to the permanent endowment made in accordance with the direction of the applicable donor gift instrument at the time the accumulation is added to the fund. The remaining portion of the donor-restricted endowment fund that is not classified as permanently restricted net assets is classified as temporarily restricted net assets until those amounts are appropriated for expenditure in a manner consistent with the standard of prudence prescribed by UPMIFA. From time to time, the fair value of assets associated with individual donor-restricted endowments may fall below the original corpus the fund included in permanently restricted net assets due to unfavorable market fluctuations subsequent to the investment of the gift. Deficiencies of this nature, which are reported in unrestricted net assets,

109 totaled approximately $2,012,000 and $2,212,000, at June 30, 2017 and 2016, respectively. Subsequent gains that restore the fair value of the assets of the donor-restricted endowment fund are classified as an increase in unrestricted net assets. Endowment net assets consisted of the following at June 30, 2017 and 2016:

110 (b) Return Objectives and Risk Parameters The Institute has adopted investment and spending policies for endowment assets that attempt to provide a predictable stream of funding to programs supported by its endowment while seeking to maintain the purchasing power of the endowment assets.

(c) Strategies Employed for Achieving Objectives The Institute manages its investments in accordance with a total return concept and the goal of maximizing returns within acceptable levels of risk. The Institute relies on a total return strategy in which investment returns are achieved through both capital appreciation (realized and unrealized) and current yield (dividends and interest). The Institute’s spending policy is designed to provide a stable level of financial support and to preserve the real value of its endowment.

(g) Bond Swap Agreement On December 22, 2008, the Institute entered into a swap agreement with Wells Fargo Bank covering $28,900,000 of outstanding 2006 Series B Bonds that required the Institute to pay a fixed rate of 3.7702% to Wells Fargo Bank in exchange for Wells Fargo Bank agreeing to pay the Institute a variable rate equal to 67% of the USD-LIBOR-BBA rate with a term of three months, payable monthly, on an identical notional amount. The notional value of the 2006

112 Series B Bond is $23,400,000. The effective date of the swap was December 22, 2008 and the termination date of the swap agreement coincides with the maturity of the bonds, which is July 1, 2031. The Institute entered into this swap agreement with the intention of lowering its effective interest rate. At June 30, 2017 and 2016, the fair value of the interest rate swap was ($3,477,319) and ($5,127,858), respectively. The unrealized gain (loss) recognized during the years ended June 30, 2017 and 2016 in the amount of $1,680,539 and ($996,198), respectively, is reported in the statements of activities in change in fair value of bond swap liability. The swap agree- ment utilizes Level 2 inputs to measure fair value. The fair value of the interest rate swap was determined using pricing models developed based on the LIBOR swap rate and other market data. Under the swap agreement, the Institute may be required to post collateral to the counterparty if certain triggering events (rates and dollar thresholds) are met. As of June 30, 2017 and 2016, there was no requirement to post collateral imposed by the swap counterparty. The bonds are repayable as follows at June 30, 2017:

Interest payments are due on demand and interest accrues for the $20,000,000 line of credit at the LIBOR rate plus 90 basis points, which was 2.63% as of June 30, 2017 and for the $30,000,000 line of credit at LIBOR rate plus 50 basis points, which is 2.23% as of June 30, 2017. There were no borrowings in fiscal year 2017 or 2016 against the lines of credit. No interest expense was incurred for the years ended June 30, 2017 and 2016.

(8) Pension Plans and Other Postretirement Benefits Separate voluntary defined contribution retirement plans are in effect for faculty members and eligible staff personnel, both of which provide for annuities, which are funded, to the Teachers Insurance and Annuity Association and/or the College Retirement Equities Fund. Contributions are based on the individual participant’s compensation in accordance with the formula set forth in the plan documents on a nondiscriminatory basis. Contributions for the years ended June 30, 2017 and 2016 totaled approximately $2,250,588 and $2,220,500, respectively. In addition to providing pension benefits, the Institute provides certain health care and life insurance benefits for retired employees and faculty. Substantially, all of the Institute’s employees may become eligible for these benefits if they meet minimum age and service requirements. The Institute accrues these benefits over a period in which active employees become eligible under existing benefit plans.
