* 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 ($3.8m this quarter). Holder counts are more reliable. Implied quarter-end price ≈ $23.26. Options: 7 managers hold calls ($1.5m notional), 4 hold puts ($132.2k).
