2 Trade and other receivables (XLS:) Download millions of € Dec. 31, 2018 Dec. 31, 2017 Trade receivables 9,988 9,553 Other receivables 0 169 9,988 9,723 Of the total of trade and other receivables, EUR 8,300 million (December 31, 2017: EUR 8,125 million) is due within one year. The increase in trade receivables is primarily due to the increase in receivables in both the United States and Germany operating segments. In the United States operating segment, this increase was the result of the higher volume of receivables for handsets sold under installment plans and the larger customer base. Exchange rate effects from the translation of U.S. dollars into euros also contributed to the increase. Offsetting effects resulted in particular from reclassification and remeasurement effects from the mandatory first-time application of the accounting standards IFRS 9 and IFRS 15. For example, receivables from long-term construction contracts in the amount of EUR 0.2 billion which until 2017 were accounted for in accordance with IAS 11 were reclassified as contract assets as of January 1, 2018.
