Return Reference	Explanation
Part III, Line 1A, Part III Line 4	The Museum has extensive collections of specimens and artifacts that constitute a record of life on Earth. These valuable, and sometimes irreplaceable, collections have been acquired through field expeditions contributions and purchases since the Museum's inception and represent one of the largest and most important natural history collections in the world. More recent collection areas include the Museum's frozen tissue collection of DNA and tissue samples as well as large scientific databases of genomic and astrophysical data. The collections provide a resource for scientists around the world, and grow significantly each year. In accordance with accounting policies generally followed by museums, the value of the Museum's collections is not reflected in the consolidated statement of financial position. The Museum's collections policy requires that the proceeds from the sale of collection items be used for acquisitions to the collections. If the assets used to purchase the collection items are from restricted funds, proceeds from the sale of those items are recorded as increases in net assets with donor restrictions in that fund until an acquisition is made.
Part V, Line 4	The Museum's endowment funds include both donor-restricted and board of trustees designated funds. These funds are invested under the oversight of the board's investment committee working with outside investment advisors, and are used to support operating, capital, and other activities pursuant to appropriations recommended by the board's budget and finance committee and approved by the board of trustees.
PART X, FIN 48 (ASC 740)	U.S. GAAP requires that a tax position be recognized or derecognized based on a "more likely than not" threshold. This applies to positions taken or expected to be taken in a tax return. The Museum does not believe its consolidated financial statements include any uncertain tax positions that would have a material adverse effect on its financial conditions.

ReturnReference	Explanation
PART I, LINE 2	The use of grant funds outside the United States in research collaboration is monitored in accordance with the AMNH sub-award administration and monitoring policy, the AMNH grants manual, and title 2 U.S. code of federal regulations ("CFR") part 200, uniform administrative requirements, cost principles, and audit requirements for federal awards ("Uniform Guidance") requirements. The Museum performs an assessment of the grantee's ability to perform the work required prior to granting an award. Post-award risk based monitoring is accomplished through periodic reporting from grantees regarding the use of grant funds, field investigations and site visits conducted by AMNH staff, and regular contact with the grantee. Because foreign grantees are not subject to Uniform Guidance, in accordance with Uniform Guidance AMNH utilizes additional methods of monitoring in the form of more frequent and extensive reporting and review by AMNH.

Return Reference	Explanation
Part I, Line 1 & Part III, Line 1	Overview The American Museum of Natural History ("AMNHthe "Museum") is one of the largest natural history museums in the world, located within the approximately 18-acre Theodore Roosevelt Park, across from Central Park in the borough of Manhattan in New York City. Founded in 1869 by a special act of the legislature of the State of New York, the Museum is chartered as an educational institution, and its scientific research, educational programs, and exhibitions are under the auspices of the Board of Regents of the State of New York. The Museum's mission, which reflects a close integration of science and education, is "to discover, interpret and disseminate-through scientific research and education-knowledge about human cultures, the natural world, and the universe." The Museum's research enterprise includes full-time scientists; the Richard Gilder Graduate School, which confers the Ph.D. degree in comparative biology and the Master of Arts in Teaching (MAT) degree, the only such free-standing degree-granting programs in any museum in the U.S.; scientific collections of more than 30 million specimens and objects that constitute an invaluable record of life on Earth; and one of the largest natural history libraries in the world. Visitors to the Museum are welcomed to more than 40 permanent exhibition halls that showcase scientific collections, including the Rose Center for Earth and Space, which houses the world-renowned Hayden Planetarium and Hayden Planetarium Space Theater, which offers live presentations and screens the Museum's Space Shows; special exhibition galleries that display award-winning exhibitions presenting current science in compelling and interactive formats; theaters for symposia and public programs. In May 2023, the Museum opened the Richard Gilder Center for Science, Education, and Innovation, a new facility with an entrance from Columbus Avenue that includes exhibition galleries, learning spaces and classrooms, collections storage, research laboratories, a library and learning center, and visitor amenities. Scientific Research The Museum's scientific research is carried out with a full-time scientific staff of approximately 170 who work in the biological sciences, paleontology, astrophysics, Earth and planetary sciences, and anthropology. Museum scientists typically conduct more than 50 expeditions each year around the world and publish their research in peer-reviewed journals. The science effort is led currently by 34 tenured or tenure-track curators whose research publications have attracted over 250,000 citations. The average citation index (h-index) for senior curators is over 50, regarded as an indication of "outstanding" impact characteristic of only top research institutions. The work of scientists and others at the Museum is partially funded by federal agencies, including the National Science Foundation (NSF) and the National Aeronautics and Space Administration (NASA). Research facilities include the Museum's collections, a natural history library, and state-of-the-art laboratories, as well as offsite research facilities available through university consortia and other partnerships. Additionally, the Museum owns and operates a biological field station in the Chiricahua Mountains of southeastern Arizona, an area of incredible biodiversity, and from which it offers classes and accommodations for visiting researchers. The Museum's cross-disciplinary research centers include an Institute for Comparative Genomics which advances basic research in molecular biology and includes three genomics laboratories; a laboratory for the study of ancient DNA and Paleoproteomics; the Ambrose Monell Cryo Collection for molecular and microbial research (a frozen tissue repository of DNA and tissue specimens); and a high-performance computing facility. The Museum's Center for Biodiversity and Conservation (CBC) surveys and studies biological diversity, provides educational and training programs, and strives to mitigate threats to the Earth's ecosystems through projects based in locations such as Colombia, Vietnam, Solomon Islands, American Samoa, Cuba, Bolivia, Canada, Ecuador, Mexico, Madagascar, Mongolia, Peru, and the Bahamas. CBC is also working to develop tools to support the professionalization of the global protected area workforce and to incorporate Indigenous and local knowledge into biodiversity assessments. Scientific Collections The Museum's collections total more than 30 million specimens and objects and are among the largest and most comprehensive in the world. The collections constitute an invaluable record of life on Earth and are maintained to facilitate the study and understanding of 4.5 billion years of change in Earth's geology, climate, and the 3.5-billion-year history of its habitats and life forms, and global cultures. In FY24, the collections grew by more than 42,000 new specimens and objects. Newer collections and facilities include the Museum's frozen tissue collection of DNA with more than 133,000 tissue samples that form a repository for research at the Museum and other institutions. Other newer forms of collections include large scientific digital databases of genomic and astrophysical data. With the opening of the Richard Gilder Center for Science, Education, and Innovation, the Museum added the Louis V. Gerstner, Jr. Collections Core, a five-story facility that combines working collections storage space with exhibitions about the central role of scientific collections and a new Lepidoptera collections facility. Together, these house more than 4 million scientific specimens, including the Museum's ichthyology collection, fossil fish, butterfly, and mammal specimens. The Museum provides research material to other institutions, typically lending tens of thousands of specimens each year (more than 700 loans of 17,000 specimens in FY24) and with outstanding loans of hundreds of thousands of specimens at any given time. Its collections are also made available for study on site to research scientists and students. A total of 874 researchers visited the collections in FY24. Library The American Museum of Natural History was established as a natural history museum and library in 1869. Since that time, the library has grown into one of the largest natural history libraries in the world, with a collection on topics that span the full range of the natural sciences; a rich archival collection of documents, photography, moving images, art, and memorabilia documenting the history of the Museum, its scientists and staff, scientific expeditions, and research, Museum exhibitions, and educational offerings; and an extensive rare book collection of more than 15,000 volumes, some dating to the 15th century. The Library serves and supports the work of the Museum staff of scientists, students, educators, and exhibit developers as well as local students, faculty, researchers, and the general public in addition to scholars nationally and around the world. In May 2023, the Library opened in a new space, the David S. and Ruth L. Gottesman Research Library and Learning Center in the Museum's Richard Gilder Center for Science, Education, and Innovation. The new Gottesman Research Library and Learning Center includes a public Reading Room, dedicated Scholar's Room for visiting researchers, and an alcove exhibit gallery that showcases holdings from its special collections. Richard Gilder Graduate School (RGGS) The Museum's Richard Gilder Graduate School, which was authorized in 2006 by the New York State Board of Regents, is home to two graduate programs: the Ph.D. in Comparative Biology and the Master of Arts in Teaching (MAT) Earth Science Residency Program. Now in its thirteenth year, the innovative MAT program enjoys a nearly 100 percent job placement rate. As of the close of FY24, the MAT Earth Science Residency Program has graduated 185 teachers; approximately 15,000 students are being taught annually by graduates of the program, mainly in high-needs schools in New York. Teacher retention exceeds national averages, particularly for those teaching in high-needs schools. Since its first cohort of Ph.D. students entered in 2008, the RGGS has graduated 47 Comparative Biology Ph.D. program doctoral degree recipients. To further advance training of the next generation of scientists, RGGS has a collaborative doctoral student training program in partnership with five local universities: The City University of New York, Columbia University, Cornell University, New York University, and Stony Brook University, and maintains an active post-doctoral program. RGGS also offers two longstanding NSF-supported undergraduate training programs, the Research Experiences for Undergraduates (REU) program, which provide a select group of 16-20 undergraduate students annually with intensive summer research experience in such subjects as evolutionary biology, Earth and planetary sciences, and astrophysics.
Part I, Line 1 & Part III, Line 1 (Continued)	Education The Museum's education programs draw on the Museum's collections, exhibitions, and other resources to support science education for all learners. Offerings include courses and programs for students starting in pre-K through high school, including training in science practices and laboratory skills; professional development for teachers, including online and on-site courses and courses for graduate credit; public programs that include lectures for adults and festivals for families; and, through the Richard Gilder Graduate School, graduate programs in comparative biology and science teaching. One of the Museum's signature educational programs for students and teachers, Urban Advantage, is a 21-year-old enrichment program developed by the Museum with the New York City Department of Education and operated by the Museum and seven other science institutions in New York City. In FY24, Urban Advantage reached 83,500 middle school students and 835 teachers in 254 middle schools across all five boroughs in New York City, along with 9,400 elementary school students and 112 teachers in 57 elementary schools. In addition, the Museum is a top field trip destination for New York City school groups and provides resources, including Educators Evenings and online Educator's Guides, to help teachers plan field trips and pre- and post- visit activities. Approximately, 283,000 students, teachers, and chaperones visited the Museum as part of organized school or camp groups in FY24. The Museum also produces and distributes curricula, lesson plans, and resource materials for classroom use, as well as for use in libraries and community organizations, to support science teaching and learning in New York City and beyond. These materials are widely available online to communities throughout the state of New York, the U.S., and the world. With the opening of the Richard Gilder Center for Science, Education, and Innovation, the Museum piloted a new program, Beyond Elementary Explorations of Science (BEES), a field trip residency for New York City public schools that provides a weeklong learning experience based in the Museum's new state-of-the-art classrooms and exhibition halls. Each residency is co-planned by Museum educators and classroom teacher(s), with guest talks by Museum scientists. In 2023-24, the program served 450 students and 53 teachers from all five boroughs of New York City. Exhibition With the opening of the Gilder Center, the Museum added new permanent galleries, including: -Susan and Peter and J. Solomon Family Insectarium: this 5,000-square-foot gallery presents live insects, pinned specimens, graphic and digital exhibits, miniature dioramas, and larger-then-life models to highlight more than 100 insect species with engaging exhibits that offer visitors opportunities to explore why these tiny animals are essential to the plant, to their ecosystems, and to humankind. -Louis V. Gerstner Jr. Collections Core and Macaulay Family Foundation Collections Galleries: this five-floor facility contains three floors of 35 engaging exhibits, with glimpses into working storage, including the Macaulay Family Foundation Collection Galleries on the first and second floors, with more than 3,000 specimens and objects displayed in floor-to-ceiling displays and interactive media touch screens that showcase the breadth of the Museum's collections and highlight what collections can tell us about the past, present and future. -Davis Family Butterfly Vivarium: this 2,500-square-foot vivarium is a year-round experience that features hundreds of free-flying butterflies among lush vegetation in tropical temperatures, with a pupae incubator, a separate display of moths, interactive displays, and dedicated staff who interact with visitors to help identify species. -Susan S. and Kenneth L. Wallach Gallery and the Invisible Worlds Immersive Experience: An introductory gallery with a winding approach to a 360-degree immersive venue introduces visitors to the ways in which all life on Earth is connected, with video projections, digital interactives, and other exhibits, leading to a wide, oval space that offers an immersive and interactive experience illustrating the interdependence within Earth's ecosystems and connections across all scales-from satellites to neurons in the human brains. Temporary Exhibitions In addition to exhibitions in its permanent galleries, the Museum creates and mounts its award-winning exhibitions, and planetarium shows (Space Shows) for display at the American Museum of Natural History as well as for distribution to museums, science centers, and planetariums in numerous venues in more than 25 countries. In FY24, the Museum toured approximately 12 exhibitions that originally opened in New York, including Pterosaurs: Flight in the Age of Dinosaurs, Sharks, T. Rex: The Ultimate Predator, The Nature of Color, and Unseen Oceans. Exhibitions that opened at the Museum in FY24 included: -Ice Cold: An Exhibition of Hip-Hop Jewelry (May 9, 2024-January 5, 2025), on view in the Melissa and Keith Meister Gallery in the Allison and Roberto Mignone Halls of Gems and Minerals, showcased more than 60 of hip-hop's most important jewelry pieces from the 1970's to the present in a celebration of the artistry and innovation that elevated hip-hop to a global phenomenon. -Grounded by Our Roots (April 3, 2024-April 21, 2025) features the work of five emerging artists from Nations of the Northwest Coast, in the contemporary gallery in the Northwest Coast Hall. The exhibition was organized by Guest Curator Aliya Boubard (Anishinaabekwe) of the Bill Reid Gallery of Northwest Coast Art in Vancouver, BC. -Opulent Oceans (April 2, 2024- ongoing) was inspired by the book Opulent Oceans: Extraordinary Rare Book Selections from the American Museum of Natural History Library, by Dr. Melanie L.J. Stiassny, the Axelrod Research Curator and Curator in the Department of Ichthyology, and features striking, large-format reproductions from 32 rare and beautifully illustrated scientific works from the Museum's Library. -The Secret World of Elephants (November 10, 2023-August 3, 2025) reveals how elephants' remarkable anatomy makes survival today possible, how elephants build and maintain their forest and savanna ecosystems, and how they communicate, raise their young and mourn the dead.
