      <Desc>THE U.S. DEPARTMENT OF ENERGY (DOE) AWARDED THE MANAGEMENT AND OPERATING CONTRACT FOR FERMI NATIONAL ACCELERATOR LABORATORY (FERMILAB) TO FRA, LLC, EFFECTIVE JANUARY 1, 2007. FRA BUILDS ON UNIVERSITIES RESEARCH ASSOCIATION'S 40-YEAR RECORD OF PERFORMANCE IN THE MANAGEMENT AND OPERATION OF FERMILAB; AND THE UNIVERSITY OF CHICAGO'S LEADERSHIP OF ARGONNE NATIONAL LABORATORY (ANL) SINCE ITS FOUNDING AS THE FIRST NATIONAL LABORATORY. THE FRA TEAM BRINGS RESOURCES, COLLABORATIONS, AND BEST PRACTICES TO ADDRESS THE LABORATORY'S CHALLENGES AND OPPORTUNITIES. FRA SUPPORTS LABORATORY DIRECTOR NIGEL LOCKYER'S LONG-TERM VISION AND TOTAL COMMITMENT TO DISCOVERY, THE DOE SCIENTIFIC MISSION, AND ENSURING OUR NATION'S CONTINUED PREEMINENCE IN PARTICLE PHYSICS. Presently, Fermilab's primary ten-year goal is to establish a world-leading neutrino science program led by the Long-Baseline Neutrino Facility and Deep Underground Neutrino Experiment (LBNF/DUNE). LBNF/DUNE advances the Particle Physics Project Prioritization Panel (P5) plan by establishing the first phase of this facility with a new beamline and a far detector sited deep underground in South Dakota in the 2020s. As Fermilab steps into this new role as host lab for LBNF/DUNE, the organizational structure is adjusting to support the scientists, students, technicians and engineers who are and will be working at the Sanford Underground Research Facility (SURF) in South Dakota. The laboratory has established a new Fermilab division, the South Dakota Operations Division, which is based full-time at SURF to provide the same range of operational and support services that exist at Fermilab's main campus in Batavia, IL. In addition, Fermilab's major initiatives include leading one of the five DOE National Quantum Information Science (QIS) Research Centers. The Superconducting Quantum Materials and Systems Center (SQMS) has the concrete and ambitious goal to develop, build, and deploy the first quantum computer at Fermilab. The SQMS Center and other Fermilab efforts are producing high-impact results in quantum computing, networking, and sensing and growing collaborations with universities, laboratories, and industry leaders in QIS.</Desc>

        <ExplanationTxt>FRA has received a determination letter from the Internal Revenue Service (IRS) indicating that it is exempt from income taxes under Section 501(c)(3) of the Internal Revenue Code. Accordingly, no provision for federal or state income taxes is included in the financial statements. There were no income tax-related interest or penalties recognized by FRA for the two years ended September 30, 2021 and September 30, 2020. FRA has not been examined by any tax jurisdiction. FRA has no ongoing federal, state or local tax audits. FRA does not expect the total amount of unrecognized tax benefits to significantly change in the next 12 months. FRA had no uncertain tax positions during 2021 or 2020. If FRA incurs interest and penalties, FRA recognizes interest and penalties related to unrecognized tax benefits in interest and income tax expense, respectively.</ExplanationTxt>
