Perpetual growth rates:
Factors that have been taken into consideration are estimates from the local Central Banks in the countries where the Group operates relating to the growth of the local economies over the next years along with the co-relation that exists between the growth of the economy and that of the construction sector.

Discount rates:
Discount rates represent the current market assessment of the risks specific to each CGU, taking into consideration the time value of money and individual
risks of the underlying assets that have not been incorporated in the cash flow estimates. The discount rate calculation is based on the specific
circumstances of the Group and its operating segments and is derived from its weighted average cost of capital (WACC). The WACC takes into account
both debt and equity. The cost of equity is derived from the expected return on investment by the Group’s investors. The cost of debt is based on
the interest bearing borrowings the Group is obliged to service. Country-specific risk is incorporated by applying individual beta factors.
The beta factors are evaluated annually based on publicly available market data.

Sensitivity of recoverable amounts
On 31 December 2017, the Group analyzed the sensitivities of the recoverable amounts of each CGU to a reasonable possible change of a key assumption (notably to a change of one point in the discount rate or the perpetual growth rate).
Impairment of Goodwill
The 2017 annual goodwill impairment testing process resulted in an impairment of €1.4 million being recorded in South Eastern Europe, as the carrying amount of a trading company of the Group exceeded its recoverable amount. The calculation of value in use was based on a discount rate of 3.1%.
During 2016, the considerable decrease of a terminal's commercial viability in South Eastern Europe resulted in the recognition of an impairment loss €2.8 million. The calculation of value in use was based on a discount rate of 8.2%. Furthermore, the significant reduction in demand of construction materials in Greece, due to the persisting economic recession, led to the reduced revenues compared to the last year forecasts. As a result, the Group recorded an impairment loss of €2.5 million on the goodwill, based on the respective value in use as calculated using a discount rate of 9.5%.
