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 ($364.7k this quarter). Holder counts are more reliable. Implied quarter-end price ≈ $8.04. Options: 14 managers hold calls ($86.0m notional), 6 hold puts ($52.0m).
