The decline of EUR 2.1 billion in current originated loans and receivables was mainly attributable to the utilization of a cash deposit of EUR 2.0 billion placed with the U.S. telecommunications authority in June 2016 in connection with the spectrum auction concluded in the second quarter of 2017. The reduction of EUR 1.3 billion in the carrying amount of available-for-sale assets primarily relates to a total impairment equivalent to EUR 1.5 billion (2016: EUR 2.2 billion) of the stock exchange-traded financial stake in BT recognized in profit and loss in 2017.
With respect to the originated loans and receivables that are neither impaired nor past due, there are no indications as of the reporting date that the debtors will not meet their payment obligations.
Receivables of EUR 504 million (December 31, 2016: EUR 235 million) were used in connection with collateral agreements as surety for potential credit risks arising from derivative transactions.
Available-for-sale financial assets in the amount of EUR 187 million were recognized at cost as of December 31, 2017
(December 31, 2016: EUR 126 million). No plans existed as of the reporting date to sell these instruments.
