Shareholders of AFFILIATED MANAGERS GROUP, INC.
Two shareholders are currently on record for AFFILIATED MANAGERS GROUP, INC., reflecting the stock ledger maintained under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing. The largest of these is Vanguard Group Inc, holding 12.8% — the largest recorded stake — followed by VANGUARD INDEX FUNDS-Vanguard Small-Cap Value Index Fund at 1.9%. Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Those 177 subsidiaries span United States, Cayman Islands, The Bahamas, Barbados, Canada, South Africa, and 1 more jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. 13 of the 177 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
