The personnel provisions consist mainly of obligations to employees relating to anniversary bonuses, temporary assistance benefits and those deriving from the early retirement agreements. Provisions for environmental risks primarily related to clean-up measures at the Lünen site as well as in Buffalo, USA and Zutphen, Netherlands. The provisions have terms of up to 24 years. The probable costs are determined taking into account past experience in comparable cases, existing appraisals and the clean-up methods that will probably be used on the basis of present knowledge.
