* 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 ($2.0m this quarter). Holder counts are more reliable. Shares outstanding: 133.1m as of 2026-08-05, 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 ≈ $16.97. Options: 6 managers hold calls ($10.0m notional), 7 hold puts ($25.8m).
