* 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 ($891.1k this quarter). Holder counts are more reliable. Shares outstanding: 131.6m as of 2025-07-29, 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 ≈ $8.47. Options: 10 managers hold calls ($12.9m notional), 10 hold puts ($7.4m).
