* 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 ($2.9m this quarter). Holder counts are more reliable. Implied quarter-end price ≈ $65.22. Options: 5 managers hold calls ($2.2m notional), 5 hold puts ($1.2m).
