* 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 ($5.5m this quarter). Holder counts are more reliable. Implied quarter-end price ≈ $51.43. Options: 10 managers hold calls ($167.7m notional), 15 hold puts ($74.9m).
