AI Transparency Report

The American Astronomical Society (AAS) demonstrates a generally stable financial position, with assets consistently exceeding liabilities over the past decade. While revenue has fluctuated, it has shown an upward trend, reaching $19,197,016 in 2023. The organization has experienced operating deficits in several recent years, including 2023 ($19,197,016 revenue vs. $21,907,187 expenses) and 2022 ($19,541,464 revenue vs. $19,786,193 expenses), indicating that expenses have sometimes outpaced income. However, the substantial asset base of $25,423,957 in 2023 provides a buffer against these short-term deficits. The AAS exhibits strong transparency regarding executive compensation, reporting 0% for officer compensation across all available filings. This suggests that the organization's leadership is either unpaid or compensated through other means not categorized as 'officer compensation' on the 990, which warrants further investigation for a complete picture. The consistent filing of IRS Form 990s over 13 periods further underscores a commitment to regulatory compliance and public disclosure.
