* 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 ($7.4m this quarter). Holder counts are more reliable. Implied quarter-end price ≈ $41.72. Options: 10 managers hold calls ($19.6m notional), 9 hold puts ($15.5m).
