* 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 ($10.7m this quarter). Holder counts are more reliable. Implied quarter-end price ≈ $59.34. Options: 10 managers hold calls ($34.6m notional), 12 hold puts ($20.6m).
