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 ($8.2m this quarter). Holder counts are more reliable. Implied quarter-end price ≈ $20.29. Options: 8 managers hold calls ($3.1m notional), 6 hold puts ($851.2k).
