Shares that two managers' reports both contain – a subsidiary's holdings that its parent's report includes too, or a sub-adviser's in its client's – are counted once ($20.6m this quarter). Holder counts are more reliable. Implied quarter-end price ≈ $257.46. Options: 6 managers hold calls ($21.5m notional), 7 hold puts ($12.5m).

Major shareholders (over 5%)

Each holder's latest filing, from 19 Dec 2024 on; percentages are of the share class, as the holder worked them out.
