* 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 ($1.4m this quarter). Holder counts are more reliable. Shares outstanding: 66.2m as of 2023-04-17, 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 ≈ $53.60. Options: 11 managers hold calls ($6.3m notional), 10 hold puts ($3.1m).

Each holder's latest filing, from 19 Dec 2024 on; percentages are of the share class, as the holder worked them out.

Their holding: how much the trade added to or took from the insider's holding (direct, or the trust or fund named). The same trade is sometimes reported by more than one insider, such as a fund and the director who represents it; totals count it once. A value is left blank where the reported price is far from the market price (usually a typo).
