It is with equally great regret that I must inform you that the source of information on the personal wealth of those other individuals you mention isnt strictly limited solely to a blog on Forbescom or otherwise Many crossreferencing using various reliable sources of data and audits exists for those people As mentioned earlier Forbescoms blog post on Agostinelli isnt sourced with any data whatsoever therefore no one is in any position to decipher where they obtained their information The financial journal OGFJ cites the  billion fund value in what would appear to be as reliable as one can get given the disclosure came in the context of a major financial transaction which would have implied due diligence The Forbescom blog source must therefore be treated accordingly and not taken as gospel or absolute For all we know it could be a wellorchestrated public relations bamboozling It certainly wouldnt be the first time Until reliable personal hard fiscal data and financials are available on this individual himself it seems this article is duly balanced particularly to reflect the various facets of this specific debate Good day
