Acquired intangible assets are recognised at cost and amortised using the straight-line method over their expected useful life. Intangible assets with an indefinite useful life are tested annually for impairment. There is also an annual review to assess whether the useful life is still indefinite. Own work for intangible assets is capitalised if the necessary conditions are met. Otherwise, it is charged to the income statement as it arises. Trademarks/domains are classified as intangible assets with an indefinite useful life if they can be used and renewed at no material cost and for an indefinite time and such a possibility is envisaged. The following amortisation periods apply:

• Goodwill: no amortisation
• Brand rights – Tamedia segment: 8–20 years
• Brand rights – other segments: no amortisation
• Customer bases: 5–20 years
• Capitalised software project costs: 3–5 years

Impairment tests are performed on intangible assets with finite useful lives if events or changes in circumstances indicate that the carrying amounts may be impaired. The determination of their impairment is based on estimates and assumptions made by the Executive Management and the Board of Directors. As a result, it is possible that the actual values realised may deviate from these estimates. If the carrying amount is higher than the recoverable amount, an impairment is recognised in the income statement to the value which appears to be recoverable based on the discounted, anticipated future income, or a higher net sales value.
