* 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 ($28.2m this quarter). Holder counts are more reliable. Implied quarter-end price ≈ $6.90. Options: 14 managers hold calls ($11.0m notional), 13 hold puts ($15.2m).
