* Summed across managers. 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 ($773.2k this quarter). Holder counts are more reliable. Implied quarter-end price ≈ $84.83. Options: 4 managers hold calls ($5.5m notional), 2 hold puts ($3.7m).

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