13. Intangible assets and Goodwill

In 2013, the Group recorded an impairment of goodwill amounting to €0.8 mil. in the income statement. The impairment was recorded as certain assumptions that had been used for the goodwill impairment test of a Group subsidiary operating in Greece were not verified.

In 2012, the total amount of the impairment of the intangible assets, excluding goodwill, stood at €5.0 mil., of which €3.1 mil. relates to the impairment of mining rights in Greece and the remaining €1.9 mil. relates to the impairment arising from the re-measurement in fair value of the Carbon Emissions Rights (CER) that the Group possessed as at 31.12.2012.

In the second semester of 2012, the US based Group subsidiary Separation Technologies LLC acquired the equipment and rights of fly ash processing at a thermal power plant in Florida. Based on the agreement, Separation Technologies LLC undertook the liability of the plant's site restoration. The Group posted the amount of €2.4 mil. in the account of other intangible assets, as the present value of the site restoration cost (note 26).
