- Each value is checked against Seagate Technology Holdings plc's share prices from within about three months of its report date (insiders' Form 4 trades and the latest close).
- Value not shown for 6 rows: no share price from within three months of their report dates is on file, so they could not be checked.
- 8 rows left out: they repeat the same share count and value quarter after quarter, which a market value cannot do.
Filer report history
Two reports per filer, as filed. No change is calculated, because the data on file cannot confirm that both reports describe the same security. Filers with a row left out above, or with no row above to check, are not listed.
