The ultimate parent company of the Wolters Kluwer group is Wolters Kluwer nv. In 2002, Wolters Kluwer nv abolished the voluntary application of the structure regime (structuurregeling). As a consequence, the structure regime became applicable to Wolters Kluwer Nederland bv, which is the parent company of the Dutch operating subsidiaries. Wolters Kluwer International Holding bv is the direct or indirect parent company of the operating subsidiaries outside the Netherlands.
