* 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 ($7.9m this quarter). Holder counts are more reliable. Shares outstanding: 268.3m as of 2022-12-31, 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 ≈ $8.93. Options: 6 managers hold calls ($9.9m notional), 5 hold puts ($4.7m).
