      <MissionDesc>The primary purpose of the organization is to examine and report on public policy issues related to Science and Technology that affect the State of California. CCST is a non-partisan, nonprofit organization that was established as an independent science advising body at the request of the state legislature in 1988. CCST's mission is to engage leading experts in science and technology to advise state policymakers to ensure that California policy is strengthened and informed by scientific knowledge, research, and innovation. CCST's vision for the Golden State is that California enhances its global leadership in science, technology, and innovation to guide the state, nation, and world towards a healthy economy, society, and environment.CALIFORNIA'S POLICIES ARE STRONGER WITH SCIENCE, AND CCST IS UNIQUELY QUALIFIED AS AN ORGANIZATION CREATED VIA THE LEGISLATURE TO CONVENE A STATEWIDE NETWORK OF EXPERTS ACROSS DISCIPLINES AND INSTITUTIONS. AS THIS COORDINATING BODY, CCST CAN PROVIDE IMPARTI</MissionDesc>

      <Desc>The 2023 class of Fellows marked the 14th year of placing Ph-D level scientists, engineers, and social scientists directly into legislative offices, policy committees, and more recently State Agencies and Offices of the Governor to prepare them for public service through the S&amp;T Policy Fellowship Program. Working in placements that included the California Governor's Office of Planning and Research, California Natural Resources Agency, Assembly Utilities and Energy Committee, California Department of Insurance, Senate Environmental Quality Committee, California Air Resources Board, Assembly Transportation Committee, and more, CCST S&amp;T Policy Fellows made an impact across a range of policy and regulatory fields. Altogether, CCST S&amp;T Policy Fellows have worked on over 1,400 bills, briefings, hearings, and bill analyses. There are now 158 alumni of the program, many of whom serve in positions in legislative offices and agencies. With the arrival of the 2024 class in November 2023, 172 Fellows have now been trained to work directly with policymakers as trusted staff.</Desc>

        <Desc>Over the past 35 years, CCST's approach to partnering and facilitating dialogue across institutions - including our renowned Partner Institutions - and disciplines has allowed CCST to create a collective impact that exceeds what any single institution could accomplish on its own.Collaboration continued to be key in 2023. CCST conducted a joint study with Blue Forest Conservation that investigated links between forest management, wildfire smoke, and the health sector and released a peer reviewed report, "The Human Health Benefits of Improving Forest Health in California".CCST partnered with the Federation of American Scientists, COMPASS, and Conservation X Labs to develop policy memos for the Federal Wildland Fire Mitigation and Management Commission, charged with providing wildfire policy recommendations to Congress. As a result of ongoing outreach with congressional offices, several report recommendations were included in a congressional letter to federal agencies urging them to take action to improve smoke data.CCST published "Key Challenges for California's Energy Future" to help current and incoming policymakers quickly get up to speed on key energy issues. CCST consulted with policymakers and more than 30 experts across California's preeminent academic and research institutions. The resulting peer-reviewed energy primer offers an overview of California's energy transition prepared by the Steering Committee, followed by background on eight high-level key challenges, including environmental justice and equity considerations, key policies, and resources for more information.An inaugural "Science Day" at California Natural Resources Agency kicked off S&amp;T Week 2023, CCST's annual flagship event. Science Day featured two panel discussions with leaders, "Successful Science-Based Partnerships, and A Cross-Sectoral Call to Action: Meeting California's Climate Goals While Building Resilience."Following Science Day, CCST hosted its 35th Anniversary Reception and Leadership Awards Ceremony, where it recognized California Air Resources Board Chair Liane Randolph and California State Senator John Laird as recipients of the 2023 CCST Leadership Awards for Science in Public Service.CCST Expert Briefings convene leading experts from CCST's Partner Institutions and beyond to address pressing scientific and technical questions facing California policymakers. In 2023, CCST held a series of six briefings, focused on identifying and addressing the key issues on the California policy landscape critical to ensuring long-term disaster resilience; Lithium Extraction from Geothermal Brine; Building a Domestic Lithium Supply Chain; Study: Human Health Benefits of Improving Forest Health; Agrivoltaics in California's Water-Energy-Food Nexus; Training Tomorrow's Cybersecurity Workforce; Innovations in Desalination.</Desc>

        <FormAndLineReferenceDesc>Part V, Line 4: Intended uses of the endowment fund.</FormAndLineReferenceDesc>
        <ExplanationTxt>CCST has one donor restricted endowment for the fellows program. From time to time, the fair value of assets associated with donor-restricted endowment funds may fall below the level that the donor or the Uniform Prudent Management of Institutional Funds Act (UPMIFA) requires CCST to maintain as a fund of perpetual duration (underwater endowment). At December 31, 2023 and 2022, CCST did not have any endowments that were considered to be underwater.</ExplanationTxt>

        <FormAndLineReferenceDesc>Part X : FIN48 Footnote</FormAndLineReferenceDesc>
        <ExplanationTxt>The accounting standard on accounting for uncertainty in income taxes addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under that guidance, the Organization may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by taxing authorities based on the technical merits of the position. Examples of tax positions include the tax-exempt status of the Organization and various positions related to the potential sources of unrelated business taxable income (UBIT). The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. There were no unrecognized tax benefits identified or recorded as liabilities at December 31, 2023.</ExplanationTxt>
