The net working capital is negative for € 656.2 million and dropped € 13.5 million compared to the end of 2018The change in net working capital compared to 31 December 2018 is mainly due to items with an opposite sign like the increase in current receivables (+ € 107.6 million), of which € 71.9 million from users and customers, offset by an increase in current payables of € 75.4 million and other current liabilities of € 16.9 million, as well as a decrease in other current assets of € 37.4 million.

As regards the relations with Roma Capitale, the net balance at 31 December 2019 was € 33.7 million receivable by the Group, a reduction compared to 31 December 2018. The change in receivables and payables is due to the accrual of the period and the effects of compensations.

As regards financial receivables, growth of € 44.6 million was recorded compared to the previous year, to be attributed to the accrual during the period of receivables relative to the public lighting service agreement, to the modernisation of security, to extraordinary maintenance, to the LED plan agreement and to the works relating to the public lighting service.

As described in the Consolidated Financial Statements as at 31 December 2018 as part of the activities required for the first consolidation of the Acea Group in the 2018 Financial Statements of Roma Capitale, a round table was launched to reconcile the Roma Capitale Receivables and Payables. After several meetings and communications, on 22 February 2019 the technical department of the Municipality in charge of the management of the contracts with the Acea Group communicated several objections relating to the supply of both works and services for the period 2008-2018. These objections were fully rejected by the Group.

On 26 February 2019 the General Management of the Municipality of Rome sent a communication stating that it had taken note of the objections raised by the technical department and the lack of recognition thereof by the Acea Group, and in order to find a complete resolution of the differences it proposed setting up a Joint Technical Committee with the Acea Group that could resolve the mutual claims.

Following several meetings, on 18 October 2019 the Joint Technical Committee drew up a report on the closure of the work, highlighting the results that emerged and proposing a favourable restart of the ordinary execution of the mutual obligations between the Acea Group and Roma Capitale. As a first step after the completion of the work, the parties took steps to implement the results that emerged from the discussions, restarting the payment of their respective receivables and payables.

In particular, between December 2019 and March 2020 the following offsets were made for a total of € 39.3 million; the types of receivables concerned are listed below:
