* 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 ($2.1m this quarter). Holder counts are more reliable. Shares outstanding: 77.7m as of 2025-05-02, 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 ≈ $22.00. Options: 2 managers hold calls ($512.4k notional), 3 hold puts ($71.6k).
