* 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 ($6.3m this quarter). Holder counts are more reliable. Shares outstanding: 19.9m as of 2025-04-30, 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 ≈ $165.14. Options: 15 managers hold calls ($39.3m notional), 11 hold puts ($26.6m).

Major shareholders (over 5%)
