* 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 ($424.2k this quarter). Holder counts are more reliable. Implied quarter-end price ≈ $6.89. Options: 15 managers hold calls ($31.8m notional), 14 hold puts ($7.1m).
