* 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 ($15.1m this quarter). Holder counts are more reliable. Shares outstanding: 81.3m as of 2026-07-31, 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 ≈ $25.30. Options: 1 managers hold calls ($276.1k notional), 0 hold puts (—).

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