The carrying amount of current and non-current contract liabilities increased year-on-year from EUR 2.5 billion to EUR 2.8 billion. These substantially include deferred revenues. The increase resulted from higher contract liabilities in the Germany and Europe operating segments. By contrast, the end of marketing of a business model in connection with the Equipment Installment Plan in the United States operating segment reduced contract liabilities by EUR 84 million.
