## Note 2

### Critical estimates and assumptions

The carrying amounts of certain assets and liabilities are based in part on estimates and assumptions. This applies particularly to impairment testing of goodwill (Note 14) and to defined-benefit pension obligations (Note 22). Assumptions and estimates are continually evaluated and are based on historical experience and expectations regarding future events deemed reasonable under prevailing circumstances. Tests are performed each year to determine if goodwill is impaired. The recoverable amount for cash-generating units has been determined by calculating values in use. For these calculations, certain estimates must be made.

A large part of the Group’s pension commitments for salaried employees are defined-benefit commitments covered by collective policies with Alecta. Since it is not currently possible to obtain data from Alecta on the Group’s share of commitments and plan assets, the pension plan signed with Alecta must be recognised as a defined-contribution plan. The consolidation ratio reported by Alecta does not indicate any deficit, although it is not possible to obtain detailed information from Alecta about the size of the pension commitment.

The present value of pension commitments recognised as defined-benefit commitments depends on multiple factors determined on an actuarial basis applying a number of assumptions. In establishing these assumptions, Addtech consults with actuaries. The assumptions used to determine the present value of the commitment include the discount rate, inflation and salary increases. Each change in these assumptions will affect the carrying amount of pension commitments. See also Note 22.
