* 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 ($3.6m this quarter). Holder counts are more reliable. Implied quarter-end price ≈ $65.24. Options: 13 managers hold calls ($44.5m notional), 12 hold puts ($66.7m).
