Intangible assets comprise licenses acquired for a consideration, primarily in connection with a contribution made to the investment costs for a power plant, as well as goodwill on consolidation arising in the Aurubis Group. As in the prior year, most of the goodwill (€ 17,439 thousand) relates to the Aurubis Hamburg Copper Products cash-­generating unit (CGU).

Aurubis carries out an impairment test on goodwill at least annually. For the impairment test on goodwill, the goodwill acquired in conjunction with a business combination is allocated to the CGU that is expected to benefit from the synergies of the business combination. If the carrying amount of the CGU to which the goodwill was allocated exceeds its recoverable amount, a commensurate impairment loss is recognized on the allocated goodwill.

As in the prior year, there was no requirement to recognize an impairment loss for the Aurubis Hamburg Copper Products CGU.

The recoverable amount is the higher of the fair value less costs to sell and the value in use. Aurubis determines the recoverable amount on the basis of the value in use. The value in use is determined by means of discounting future cash flows after taxes with a risk-adjusted discount rate (WACC) after taxes (discounted cash flow method).

The cash flow estimates cover a planning horizon of four years before transferring to perpetuity. The cash flows were established within the scope of a qualified planning process including internal company values based on past experience and extensive market knowledge, and they take into consideration management’s assessment and estimates regarding the future development of the regional market.

In addition to the weighted capital costs, the significant assumptions used to calculate the value in use were the forecast earnings trend and the sustainable growth rate of the terminal value at a level of 1 %.The growth rate was derived from future expectations and does not exceed the long-term average growth rates of the respective markets.

The WACC used for discounting purposes amounted to 6.5 % after taxes or 9.3 % before taxes as at September 30, 2015 (previous year: 7.5 % after taxes or 10.7 % before taxes).

As in the prior year, there was no requirement to recognize impairment losses on intangible assets with a limited useful life.

As in the prior year, no capitalized development costs were recognized in the Group as at September 30, 2015. Research costs are recognized in profit or loss for the respective periods (see Note 30).
