Reported transactions

Price 0.00 is a real reported figure on allotments, gifts and option exercises — not a missing number. The 3 most recent rows are grouped into 3 lines by date, company and transaction type — open a line to see every lot with its own source link.

How to read this list

Every row is one insider transaction as reported to FI, with a link back to the FI register filtered to that issuer and publication date. FI publishes no per-report permalink, so the link is a search, not a document. Where the record carries no price at all we leave the cell empty instead of guessing one.

The shares and money on a grouped line add up only the lots listed inside that line, and only when every one of them carries the figure. Where a group mixes more than one reporting currency we leave the money blank rather than convert — no source publishes the rate that conversion would need.
