* 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 ($148.0k this quarter). Holder counts are more reliable. Implied quarter-end price ≈ $7.77. Options: 3 managers hold calls ($245.9k notional), 2 hold puts ($3.9k).
