* 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 ($1.6m this quarter). Holder counts are more reliable. Shares outstanding: 56.7m as of 2025-07-31, 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 ≈ $81.64. Options: 4 managers hold calls ($3.8m notional), 4 hold puts ($1.9m).
