Until 1992, most of the Swedish state’s forest holdings were managed by the former Domänverket (Swedish Forest Service). On 1 July 1992, the vast majority of the forest holdings, Domänverket's forest industry and the majority of operations were transferred to Domän AB, which was owned wholly by the Swedish state. Forest lands west of the so-called cultivation limit mostly remained under direct state management.
On 31 December 1993, Domän AB acquired the wholly state owned forestry company ASSI AB. At the same time, the company’s name was changed to AssiDomän AB.
On 1 March 1994, AssiDomän made an offer to all shareholders in the listed company Ncb AB, in which the state owned approximately 51% of the shares. On 1 April 1994, AssiDomän was introduced on the stock market. State ownership then amounted to just over 50%.
In 1999, about 25% of AssiDomän’s forest land was transferred to the subsidiary
Sveaskog AB, whose shares were acquired by the state. At the same time the state’s holding in AssiDomän decreased to about 35%.
In 2001, the state acquired the remaining 65% of the shares
in AssiDomän AB through Sveaskog AB.
In 2006, Sveaskog sold AssiDomän Cartonboard in Frövi to Kinnevik’s wholly owned subsidiary Korsnäs. As a result of this sale, Sveaskog became a pure-play forest-owning company.
