* 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 ($995.6k this quarter). Holder counts are more reliable. Implied quarter-end price ≈ $46.38. Options: 2 managers hold calls ($7.3m notional), 1 hold puts ($0).
