* 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 ($101.0m this quarter). Holder counts are more reliable. Shares outstanding: 80.5m as of 2026-05-01, from the company's own SEC filing; the percentage can still exceed 100%: lent-out shares are counted by the lender and the buyer, and some reports overlap without saying so. Implied quarter-end price ≈ $108.20. Options: 13 managers hold calls ($56.7m notional), 14 hold puts ($61.6m).
