AI Transparency Report

Gustavus & Louise Pfeiffer demonstrates strong financial health with substantial assets, currently at $17,863,505 as of 2023. The organization consistently maintains a healthy asset base, indicating long-term stability. Their spending efficiency appears robust, particularly in the most recent fiscal year (2023), where expenses were $188,163 against revenues of $933,643, suggesting a conservative approach to spending relative to income. However, there have been periods of significant expense exceeding revenue, such as in 2021 where expenses were $4,671,757 against revenues of $3,508,351, and in 2019 where expenses were $5,217,835 against revenues of $2,099,996. This suggests that while recent years show efficiency, past years have seen substantial grantmaking or investment losses that led to higher expenses. The organization's transparency is bolstered by its consistent filing of IRS Form 990s, with ten filings available, providing a clear historical financial picture. The consistent reporting of 0% officer compensation across all available filings is a significant indicator of efficient use of funds, as no funds are diverted to executive salaries. This practice enhances public trust and demonstrates a commitment to directing resources towards its mission. The fluctuation in revenue and expenses over the years, while sometimes showing deficits, is typical for foundations that make significant grants, and the overall asset growth from $21,135,551 in 2011 to $17,863,505 in 2023 (with a peak of $28,142,814 in 2014) indicates a well-managed endowment, even with some market fluctuations.
