The maiden list, made in collaboration with wealth management firm, Waterfield Advisors, is primarily based on the wealth of entrepreneurs of listed firms; where the entity is unlisted, the price-earnings (PE) multiple of the sector’s index, and, in the absence of an industry index, the PE multiple of the closest-listed company from the same industry was used.
Fortune and Waterfield collected details of listed and unlisted wealth, additional information regarding investments outside of the listed business: such as stakes in other public companies (where the holding is less than 1%) and in other private entities/ start-ups, etc.
