* 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 ($66.3m this quarter). Holder counts are more reliable. Shares outstanding: 152.7m as of 2025-10-31, 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 ≈ $14.96. Options: 4 managers hold calls ($820.5k notional), 3 hold puts ($533.6k).

Each holder's latest filing, from 19 Dec 2024 on; percentages are of the share class, as the holder worked them out.
