Ownership structure
The company from the directory is at the top. Below it are the entities registered as its shareholders, and below them their owners, up to three levels.
An arrow points to the company in which the owner holds shares. Hover over or tap an arrow to see the registry entry date. A two-way arrow marks cross-shareholding.
A tile with a dashed border stands for shareholders who are natural persons, given only as a number, without names.
A line marked REGON is the ownership form that Statistics Poland reports for that entity.
Hovering over or tapping a company usually shows its NIP, REGON and KRS numbers, and the LEI number for a company from the GLEIF index. The card does not appear for the State Treasury or a family foundation.
