* 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 ($246.4k this quarter). Holder counts are more reliable. Shares outstanding: 56.6m as of 2023-03-03, 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 ≈ $6.76. Options: 4 managers hold calls ($48.5k notional), 5 hold puts ($1.0m).
