Income from the reversal of impairment losses on non-current assets mainly comprises the partial reversal in the third quarter of 2017 of impairment losses on spectrum licenses at T-Mobile US, increasing their carrying amount by EUR 1.7 billion before deferred taxes (for further information, please refer to Note 5 “Intangible assets"). Income from the disposal of non-current assets decreased by EUR 0.3 billion compared with the prior year. This was attributable to income of EUR 0.5 billion ­recognized in the prior year from transactions for the exchange of spectrum licenses between 
T-Mobile US and two telecommunications companies. Total income of EUR 0.2 billion was recorded in 2017 from transactions for the exchange of spectrum licenses completed between T-Mobile US and telecommunications companies. Miscellaneous other operating income decreased by EUR 1.6 billion year-on-year. The main items posted in 2017 were income of EUR 0.5 billion from the divestiture of Strato AG, income of EUR 0.2 billion from a payment received in connection with the settlement agreement concluded with BT in July 2017, and income of EUR 0.2 billion from the sale of the remaining shares in Scout24 AG, which had been accounted for using the equity method. In the prior year, income from the sale of stakes accounted for using the equity method included EUR 2.5 billion from the sale of the stake in the EE joint venture. Around EUR 0.9 billion of this amount was accounted for by effects recognized directly in equity in previous years.
