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 invaluable, 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.

Form And Line Reference	PART I, LINE 2	FormAndLineReferenceDesc
Explanation	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.

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 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 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; special exhibition galleries that display award-winning exhibitions presenting current science in compelling and interactive formats; and theaters for symposia and public programs. The Museum's Rose Center for Earth and Space houses the world-renowned Hayden Planetarium and the Hayden Planetarium Space Theater, which offers live presentations and screens Space Shows. The Museum's Richard Gilder Center for Science, Education, and Innovation includes exhibition galleries, theaters, classrooms, the David S. and Ruth L. Gottesman Research Library and Learning Center, laboratories, and scientific collections storage. Scientific Research The Museum's scientific research is carried out with a full-time scientific staff of approximately 170 researchers who work in physical sciences, anthropology, invertebrate zoology, paleontology, and vertebrate zoology. 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 36 tenured or tenure-track curators whose research publications have earned more than 380,000 citations. The average citation index (h-index) for senior curators is over 50, regarded as an indication of "outstanding" impact characteristics 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, 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, 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: an Ancient Biomolecules 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, Ecuador, Norway, Micronesia, and Saudi Arabia. CBC also is 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, life forms, and global cultures. In FY25, the collections grew by more than 50,000 new specimens and objects. The Museum provides research material to other institutions, typically lending tens of thousands of specimens each year (more than 300 loans of 17,000 specimens in FY25) 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 994 researchers visited the collections in FY25. David S. and Ruth L. Gottesman Research Library and Learning Center 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 from around the world. 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 and is currently accredited by the New England Commission of Higher Education ("NECHE"), is home to two degree-granting graduate programs: the Ph.D. in Comparative Biology and the Master of Arts in Teaching ("MAT") Earth Science Residency Program. Launched in 2012, the innovative MAT program enjoys a nearly 100 percent job placement rate. As of the close of FY25, the MAT Program has graduated 185 teachers, and 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 through FY25. 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, with about 30 Ph.D. students advised by RGGS faculty members at any given time. The RGGS maintains an active postdoctoral program, with about 30 postdoctoral scholars in residence annually. RGGS also offers two longstanding NSF-supported undergraduate training programs, the Museum's Research Experiences for Undergraduates ("REU") programs, which provide a select group of 16-20 undergraduate students annually with intensive summer research experiences 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 22-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 FY25, Urban Advantage reached 74,500 middle school students and 745 teachers in 260 middle schools across all five boroughs in New York City, along with 12,740 elementary school students and 135 teachers in 64 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 291,800 students, teachers, and chaperones visited the Museum as part of organized school or camp groups in FY25. 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. 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 FY25, the Museum's content reached approximately 5.8 million visitors at other venues. Touring exhibitions included T. rex: The Ultimate Predator, Unseen Oceans, The World's Largest Dinosaurs, and The Power of Poison. Exhibitions and shows that opened at the Museum in FY25 included: -Life at the Limits: Nature's Superheroes (encore presentation) -Shaping Our Future Through Tradition -Apex Stegosaurus fossil -Eyes on the Universe: Images from Space Telescopes -Cosmic Splendor: Jewelry from the Collections of Van Cleef & Arpels -Hayden Planetarium Space Show Encounters in the Milky Way
