* 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. Holder counts are more reliable. Implied quarter-end price ≈ $3.44. Options: 10 managers hold calls ($5.0m notional), 7 hold puts ($4.8m).
