- Each value is checked against Trio-Tech International's share prices from within about three months of its report date (insiders' Form 4 trades and the latest close).
- Value not shown for 19 rows: 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 Trio-Tech International'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.
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.
