The following list is based on the annual estimated wealth and assets assessment compiled and published by American business magazine Forbes.
[1] To assess and compile data on estimated wealth and assets, Forbes relies on information gathered by more than 50 reporters working in 16 countries throughout the year.
The net worth is estimated based on individuals' assets, such as stakes in public and private companies, yachts, art, and real estate.
Positions in a publicly-traded stock are priced to market on a date roughly a month before publication.
Since stock prices fluctuate rapidly, an individual's true wealth and ranking at the time of publication may vary from their situation when the list was compiled.
