- Each value is checked against Century Aluminum Co's share prices from within about three months of its report date (insiders' Form 4 trades and the latest close).
- Value not shown for 1 row: the value per share could not be confirmed against the share prices on file from within three months of the report date.
- 1 row left out: the value per share it reports is far from Century Aluminum Co's share prices on file from around the report date, far from the value most filers reported for that date, or the value of a security already left out, so it may describe another security or share class.
120 filers have only one report here.
