        <ExplanationTxt>AGI has a flexible policy to balance the shorter-term grant-making obligations with AGI's goal of providing grants into perpetuity. In establishing this policy, the Board of Directors considered the long-term expected return on the endowment, coupled with the ability to endure periods of underperformance without excessive deterioration of real principal. Accordingly, over the long term, AGI expects the current flexible spending policy to allow its endowment to grow at least at the rate of inflation. This is consistent with AGI's objective to maintain the purchasing power of the endowment assets held in perpetuity as well as to provide additional real growth through new gifts and investment return.</ExplanationTxt>

        <ExplanationTxt>The American Geosciences Institute (AGI) was founded in 1948, under a directive of the National Academy of Sciences, as a network of associations representing geoscientists with a diverse array of skills and knowledge of our planet. The Institute provides information services to geoscientists, serves as a voice of shared interests in our profession, plays a major role in strengthening geoscience education, and strives to increase public awareness of the vital role the geosciences play in society's use of resources, resilience to natural hazards, and the health of the environment. AGI connects Earth, science, and people by serving as a unifying force for the geoscience community. With a network of more than 65 member and affiliated organizations, AGI represents over a quarter-million geoscientists across the country and around the world. No matter one's individual discipline, AGI's essential programs and services will strengthen connection to the geosciences.</ExplanationTxt>
