    YEAR-DATED OWNERSHIP

    Company share entries

    The company’s own investments in other businesses. Shareholders who own the company are shown under Ownership.

    Source and scope

    Skatteetaten / Aksjonærregisteret. Every level uses the same source year and source set. Further links follow Norwegian business registration numbers; foreign identifiers are not linked automatically. Calculated share is the product of reported share count / total shares at each level, not voting rights, control, or today’s shareholder register. Partial source coverage is stated at the relevant level; unresolved calculation basis is shown without a percentage.

    Up to 500 source records examined; the view may be limited. Missing matches do not prove that ownership is absent.
