* 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 ($409.6k this quarter). Holder counts are more reliable. Shares outstanding: 6.7m 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 ≈ $37.45. Options: 1 managers hold calls ($0 notional), 1 hold puts ($0).
