Depreciation and amortization (comprising property, plant and equipment and intangible assets) decreased by €187 million in 2013, essentially due to the end of the useful life of a number of generation plants and the revision of the useful life of the nuclear generation plants in Slovakia and a number of conventional thermal generation plants, as well as assets previously classified as to be relinquished free of charge following the enactment of Law 134 of August 7, 2012. For the latter, the new law impacted all of 2013, while in 2012 it was in effect only as from August.

“Impairment losses” mainly regard writedowns of trade receivables amounting to €656 million (€588 million in 2012), the impairment of the goodwill recognized on Enel OGK-5 in the amount of €744 million (€112 million in 2012), the impairment loss on the assets held for sale of Marcinelle Energie (€14 million) following developments in negotiations with the potential purchasers and the consequent adjustment of the value of the assets to their estimated realizable value (an analogous impairment loss of €145 million was recognized for the same company in 2012), as well as impairment losses on property, plant and equipment and intangible assets of €242 million (€95 million in 2012), essentially in respect of a number of generation and storage facilities in Italy, photovoltaic manufacturing plants in Italy and geothermal generation plants in Nicaragua. The previous year, the item included the impairment of goodwill of the cash generating units “Endesa-Iberia” in the amount of €2,392 million and Endesa Ireland in the amount of €67 million.
