Note 21 - Intangible assets

In 2005, the EU introduced an emission rights system as a method for restricting carbon dioxide emissions. For the period 2008 up to and including 2012, Rexcell Tissue and Airlaid AB has been allocated 84,665 tonnes per year, Dals Långed 2,779 tonnes per year, and Skåpafors 14,154 tonnes per year. In total, 15,563 tonnes were consumed in 2011 and 18,497 tonnes in 2010. Received emission rights are reported as intangible assets booked at an acquisition value of zero.

Tests for impairment of goodwill

Tests for impairment of goodwill were carried out at the end of the financial year on December 31, 2011 and December 31, 2010. With the implementation of IFRS, allocation of the Group's goodwill items has taken place through the use of allocation ratios; see Note 4.2. 

Goodwill is allocated on the Group's cash-generating units identified per business area as follows:

Tests for impairment of goodwill take place annually and where there are indications of impairment. Recoverable amounts for cash-generating units are determined based on estimated use values. The calculations are based on estimated future cash flows before tax, based on financial forecasts approved by company management and which cover the current year as well as a five-year period. Cash flows beyond this period are extrapolated using an assessed growth rate. The growth rate does not exceed the long-term growth rate for the industry as a whole. During the period covered by the forecast, the growth rate for the Professional business area is estimated at an average of 2.2% (2010: 4.0%) per year and at 1.0% (2010: 1.0%) as a weighted average rate of growth beyond the period covered by the forecast. 

Important assumptions which are used for calculations of use values are primarily profit margin, growth rate and a nominal discount rate of 11.4% (2010: 11.4%). The discount rate before tax is used in conjunction with present value calculation of estimated future cash flows.

Company management has established profit margin and growth rate based on previous results and its expectations as regards market growth. The discount rates used are stated before tax and reflect specific risks in the business area.

Company management believes that reasonable possible changes in the significant assumptions used in the calculations would not have such a major impact as to reduce per se the recovery value to a value which is below the reported value.
