      <Desc>Research and Collections (SEE SCHEDULE O) RESEARCH AND COLLECTIONS: The Smithsonian's collections of nearly 155 million objects (art, artifacts and scientific specimens) are the heart of the institution. Research, public programs and exhibitions are based on these collections, which additionally include more than 32 million digital records of online material. Care of the collections involves the work of registrars, conservators, museum specialists, designers, curators and editors. Approximately 145 million objects and specimens are part of the National Museum of Natural History collections and are primarily used for research by both Smithsonian scientists and researchers from around the world. In some cases, the museum has the definitive, irreplaceable collection of a certain species which is essential for comparative studies. The Center for Astrophysics | Harvard &amp; Smithsonian, played a central role in capturing the first-ever image of a black hole in April. The center led an international collaboration of hundreds of scientists linking eight telescopes across four continents to capture the image that will help scientists answer fundamental questions about how the universe works. A Guam kingfisher was born at the Smithsonian Conservation Biology Institute (SCBI) in April 2019. Guam kingfishers are extinct in the wild, with only about 140 living in human care, making them one of the most endangered bird species on the planet. The species is notoriously difficult to breed, and was taken from the wild into human care in the 1980s. SCBI has hatched 20 chicks since 1985 as part of the Guam Kingfisher Species Survival Plan. Researchers from the National Museum of Natural History tripled the number of known species of electric eels. A study of the Amazon basin revealed that electric eels belong to three different species that evolved from a shared ancestor. Scientists had previously believed that the eels all belonged to a single species. The National Museum of American History and the Smithsonian's Digitization Program Office digitized 18,000 political and military posters, making them accessible for the first time to the public online.</Desc>

        <Desc>Education, Public Programs and Exhibitions (SEE SCHEDULE O) EDUCATION, PUBLIC PROGRAMS AND EXHIBITIONS: The National Museum of American History and the Smithsonian Latino Center announced the first physical gallery space on the National Mall dedicated to celebrating the U.S. Latino experience. The Molina Family Latino Gallery will open in 2021 in the National Museum of American History. It will feature 4,500 square feet of bilingual stories for all audiences through rotating exhibitions. The National Portrait Gallery opened "Votes for Women: A Portrait of Persistence" in March 2019. The exhibition examines the history of women's suffrage in the U.S. Through more than 120 portraits and objects, the exhibition outlines the more than 80-year movement for women to obtain the right to vote. The exhibition was the first to be funded by the Smithsonian American Women's History Initiative, which strives to be the nation's most comprehensive undertaking to document, research, collect, display and share the stories of women in America. The National Museum of Natural History opened a new hall of fossils, after five years of planning and construction. "The David H. Koch Hall of Fossils-Deep Time," opened in June 2019, tells the story of 3.7 billion years of life on Earth, highlighting the connections among ecosystems, climate, geological forces and evolution, through more than 700 fossil specimens. The exhibition helps visitors understand that the choices they make today will have an impact on the future. The National Air and Space Museum led the national celebration of the 50th anniversary of the Apollo 11 moon landing in 1969. To commemorate the anniversary, the museum and NASA partnered to present the Apollo 50 Festival for three days on the National Mall. The centerpiece of the festival was a full-motion projection mapping on the Washington Monument. Over half a million people visited the National Mall to see the 17-minute show that used archival footage to recreate the launch of Apollo 11 and tell the story of the first moon landing. The museum also put Neil Armstrong's Apollo 11 space suit on display, after having been off display for 13 years of conservation.</Desc>

        <ExplanationTxt>The Smithsonian Environmental Research Center (SERC) is located on 2,650 acres of land on the Chesapeake Bay in southern Maryland spanning forests, wetlands, marshes, and 12 miles of protected shoreline. The site serves as a natural laboratory for long-term and cutting-edge ecological research. The Smithsonian has a conservation easement associated with property that is immediately adjacent to SERC land owned by the Institution. Facilities and security staff visit the area regularly, and are thus able to report any unusual activity on the land subject to the easement. The organization does not separately track the hours and expenses associated with monitoring the property related to the easement.</ExplanationTxt>

        <ExplanationTxt>In conformity with the practice generally followed by museums, no value is assigned to the collections in the statement of financial position. Purchases of collection items are recognized as reductions in unrestricted net assets in the period of acquisition. Proceeds from deaccessions or insurance recoveries for lost or destroyed collection items are recognized as increases in the appropriate net asset class and are designated for future collection acquisitions.</ExplanationTxt>

        <ExplanationTxt>The acquisition, preservation, management, and study of collections are fundamental to the Smithsonian's mission to increase and diffuse knowledge and have been the foundation upon which it rests. Smithsonian collections are a national and global resource accessed each year by millions of visitors and researchers who use traditional methods and cutting-edge technologies to explore subjects from aeronautics to zoology. Through its collections, the Smithsonian presents the astonishing record of American and international artistic, historical, cultural, and scientific achievement, with a scope and depth no other institution in the world can match. Smithsonian collections contribute to population recovery of endangered species, advances in reproductive biology, genome resource banking, medical research, forensic analysis, bio-security, and conservation policy worldwide. Assembled over more than 165 years, the collections are central to the core activities and to the vitality and significance of the Smithsonian.</ExplanationTxt>

        <FormAndLineReferenceDesc>Schedule F, Part I, Line 2 Procedures for monitoring use of grant funds</FormAndLineReferenceDesc>
        <ExplanationTxt>The Office of Fellowships has central management and administrative responsibility for the Smithsonian programs of research fellowships and other academic appointments for undergraduate, graduate students, postdoctoral and senior scholars. The Smithsonian Institution Fellowship Program is a competitive fellowship program for graduate and postdoctoral fellows, who apply to conduct research at the Institution with research staff serving as advisors. The review process is made up of disciplinary committees comprised of the Institution's staff who evaluate the candidates and then select the fellows. There are other competitive and non-competitive fellowships for visiting scholar and student appointees selected through the Smithsonian units that go through a variety of other selection processes before an award is made. An official letter/agreement is provided to each award recipient identifying the award title, dates of tenure, stipend allowances, and required responsibilities for holding this position. All recipients either will identify a financial institution for receipt of their monetary award or they will receive US Treasury checks. Depending on the tenure of the appointment, payments can range from one lump sum, biweekly payments or monthly payments. Most fellowship appointments are awarded for one to two years. On occasion, the Smithsonian Institution has visiting scholars or fellows who are conducting research in another country. Payments are usually submitted as stated above, however, on occasion, there may be one or two who request that their payments be sent to the country of their research. At the end of tenure, a final report of their research accomplishments is provided for our records. Smithsonian research staff who serve as advisors to these fellows, students and scholars are usually in the field during their tenure. The eight Smithsonian research centers located in the United States and one located in Panama monitor the progress of their fellows especially those fellows in other countries, and the administrative management of funds is managed through the Institution's central administration for accountability.</ExplanationTxt>

        <ExplanationTxt>SI engaged multiple fundraising services and many work on the same campaigns. It is not possible to accurately report the exact amount of revenue associated with each fundraiser. None of these fundraisers had control of contributions; all were paid under the terms of negotiated contracts. SI closely monitors fundraising performance against established campaign goals for its contractors, and results are taken into consideration in future contract negotiations. Payments to Avalon Consulting Group of approximately $2,457,145 are not reported in Part I. This amount is for reimbursements related to expenses for postage, printing and mailing lists.</ExplanationTxt>

        <ExplanationTxt>The Office of Fellowships has central management and administrative responsibility for the Smithsonian programs of research fellowships and other academic appointments for undergraduate, graduate students, postdoctoral and senior scholars. The Smithsonian Institution Fellowship Program is a competitive fellowship program for graduate and postdoctoral fellows, who apply to conduct research at the Institution with research staff serving as advisors. The review process is made up of disciplinary committees comprised of the Institution's research staff who evaluate the candidates and then select the fellows. There are other competitive and non-competitive fellowships for visiting scholar and student appointees selected through the Smithsonian units that go through a variety of other selections processes before an award is made. An official letter/agreement is provided to each award recipient identifying the award title, dates of tenure, stipend allowances, and required responsibilities for holding this position. All recipients either will identify a financial institution for receipt of their monetary award or they will receive US Treasury checks. Depending on the tenure of the appointment, payments may be made in a lump sum or in periodic payments. Most fellowship appointments are awarded for one to two years. At the end of tenure, a final report of their research accomplishments is provided for our records. Smithsonian research staff who serve as advisors to these fellows, students and scholars are usually in the field during their tenure. The individual Smithsonian research centers monitor the progress of their fellows, and the funds are managed through the Institution's central administration to ensure accountability. Similar processes are followed for awards made to organizations whose academic staff perform the related research.</ExplanationTxt>

        <FormAndLineReferenceDesc>Schedule J, Part I, Line 1a First Class Travel</FormAndLineReferenceDesc>
        <ExplanationTxt>Chartered travel for bona-fide business purposes was authorized for two key employees when the circumstances of their travel met the requirements of the Smithsonian's policy for such travel. First class travel was approved in each instance by that individual's designated "approving official" for travel. The Smithsonian's travel policy is guided by the Federal Travel Regulations as supplemented by the Smithsonian's Travel handbook. The accountable plan for travel reimbursements maintained by the Smithsonian meets IRS requirements, therefore no portion of this travel was treated as taxable compensation.</ExplanationTxt>

        <ExplanationTxt>Items are sold through commercial galleries and auctions houses. Individuals and firms are hired on a contractual basis to process acquisitions. Although the Smithsonian acquires collection with the good faith intention of retaining them for an indefinite period of time, prudent collections management includes judicious consideration of appropriate deaccessioning and disposal to refine and improve the quality and relevance of the collections with respect to the Smithsonian's mission and purpose. When objects are deaccessioned for disposal by sale, the Smithsonian contracts with commercial galleries or auction houses to sell the objects in order to assure the best return from the sale.</ExplanationTxt>

        <ExplanationTxt>All officers, key employees, and certain other employees are required to complete and file annually a Confidential Financial Disclosure Report. These Reports - which require disclosure of certain assets, earned income, liabilities, outside positions, outside contracts and agreements, gifts, hospitality, reimbursements, and other interests related to the employee's Smithsonian position - are reviewed by the Institution's Office of General Counsel for compliance with applicable conflict of interest policies and laws. In addition to this required reporting, all key employees are required to comply with the Institution's Standards of Conduct, which, among other things, requires that employees not engage in private or personal activities that might conflict or appear to conflict with Smithsonian interests, requires that employees obtain Office of General Counsel approval before engaging in an outside activity for compensation, and requires employees to consult with the Office of General Counsel whenever a doubt exists as to whether an activity or planned activity violates the Standards. All members of the Smithsonian's governing body are required to complete and file annually the Board of Regents Annual Disclosure Statement. These statements - which require reporting by members (including any reportable interests held by immediate family of members) on outside positions and substantial shareholding in for-profit business entities, outside positions in non-profit entities, and interests and affiliations of the member that have or sought to have a relationship to the Smithsonian - are reviewed by the Institution's General Counsel for compliance with applicable conflict of interest policies and laws. In addition to this required reporting, all members of the Smithsonian's governing body are required to comply with the Board of Regents Ethics Guidelines, which, among other things, define conflicts of interest and establish procedures for disclosing and reporting of conflicts and recusal from decision-making.</ExplanationTxt>

        <ExplanationTxt>The Smithsonian ensures that compensation paid to officers and other key employees is reasonable and comparable to similar organizations. Employees of the Smithsonian may be paid with federally appropriated funds or with nonfederal ("Trust") funds. Most Trust funded (nonfederal) officer and key employee positions are subject to market-based compensation, and the Board of Regent's Committee on Compensation and Human Resources engages an independent consultant to develop and assemble comparability data for its consideration and to inform its decisions. The Committee's annual deliberations and decisions are documented as part of the final recommendation materials submitted to the Board of Regents. Salaries for Federal employees are determined by statutorily established pay ranges for civil service employees. As a matter of policy, the Smithsonian has established similar ranges for certain Trust funded officer and key employee positions and maintains those ranges in proportion to the appropriate Federal pay ranges.</ExplanationTxt>

        <ExplanationTxt>The Office of Fellowships has central management and administrative responsibility for the Smithsonian programs of research fellowships and other academic appointments for undergraduate, graduate students, postdoctoral and senior scholars. The Smithsonian Institution Fellowship Program is a competitive fellowship program for graduate and postdoctoral fellows, who apply to conduct research at the Institution with research staff serving as advisors. The review process is made up of disciplinary committees comprised of the Institution's staff who evaluate the candidates and then select the fellows. There are other competitive and non-competitive fellowships for visiting scholar and student appointees selected through the Smithsonian units that go through a variety of other selection processes before an award is made. An official letter/agreement is provided to each award recipient identifying the award title, dates of tenure, stipend allowances, and required responsibilities for holding this position. All recipients either will identify a financial institution for receipt of their monetary award or they will receive US Treasury checks. Depending on the tenure of the appointment, payments can range from one lump sum, biweekly payments or monthly payments. Most fellowship appointments are awarded for one to two years. On occasion, the Smithsonian Institution has visiting scholars or fellows who are conducting research in another country. Payments are usually submitted as stated above, however, on occasion, there may be one or two who request that their payments be sent to the country of their research. At the end of tenure, a final report of their research accomplishments is provided for our records. Smithsonian research staff who serve as advisors to these fellows, students and scholars are usually in the field during their tenure. The eight Smithsonian research centers located in the United States and one located in Panama monitor the progress of their fellows especially those fellows in other countries, and the administrative management of funds is managed through the Institution's central administration for accountability.</ExplanationTxt>
