* 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 ($750.1k this quarter). Holder counts are more reliable. Shares outstanding: 77.7m as of 2023-08-02, 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 ≈ $34.22. Options: 3 managers hold calls ($472.0k notional), 3 hold puts ($270.3k).
