* 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 ($8.0m 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 ≈ $8.99. Options: 8 managers hold calls ($5.8m notional), 4 hold puts ($1.7m).
