Restatements are detected by comparing every vintage of a fact across all of Aon plc's filings back to 1993. A revision is not by itself a sign of wrongdoing — companies re-file for many legitimate reasons. This list is not exhaustive: it shows AON's most significant revisions, and a figure absent from it has not been certified as unrevised.
Who is buying and selling Aon plc — insider transactions from Forms 3/4/5/144 and institutional ownership from 13F, 13D, and 13G filings, point-in-time stamped like every other fact in the library. Traders read it as a positioning signal; risk desks read it as concentration.
