Philanthropic Endeavors

Methodology and Data Sources

Net worth estimates are compiled from publicly available data from sources like Forbes and Bloomberg, primarily reflecting known asset values at specific points in time. They should be considered well-informed estimates, not precise accounting values.

We then adjust all historical figures to their equivalent in today's dollars, calculated using the US Consumer Price Index (CPI) published by the Bureau of Labor Statistics. This methodology provides a more accurate comparison of real purchasing power across different years.
