Could a market-valuing-method give a better measurement of fair value of standing timber than the DCF model which is current practice of the Swedish forest industry today? In 2005, IFRS was implemented in Swedish accounting and fair value became the guideline for biological asset valuation. According to IAS 41, a mark-to-model approach as the DCF, is a less preferable way of measuring fair value. In this thesis we will carefully study one large actor in Swedish forestry and explain how they use their DCF-model in practice.
