3.2 INTANGIBLE ASSETS

At 2016 year-end, the balance of intangible assets other than infrastructure projects amounted to EUR 503 million (2015 year-end: EUR 234 million). The changes in “Intangible Assets” in the consolidated statement of financial position were as follows:

The most significant changes in this line item in 2016 relate mainly to the acquisition of certain companies in the Services segment (see Note 1.1.3) where the value of the related intangible assets were allocated (see Note 3.1.1) and the other intangible assets thereof were included. The total impact amounts to EUR 352 million, of which:

• The acquisition of Broadspectrum gave rise to an impact of EUR 201 million relating to the value of the contract backlog and the customer relationships.
• In addition, the inclusion of this company resulted in an additional impact of EUR 108 million in relation to the value of additions to software.
• The acquisition of Amest Kamiensk gave rise to an impact of EUR 11 million relating to the waste treatment plant management contract.
• The acquisition of Siemsa and Biotran gave rise to impacts of EUR 6 million and EUR 4 million, respectively, in relation to the measurement of the management contracts in the energy and pharmaceuticals industries and the rights to perform them.
• The acquisition of Transchile Charrúa Transmisión resulted in the addition of EUR 21 million relating to the value of the owned contract for electricity transmission management.
• “Rights on Concessions” includes the rights to operate the tenders won in the Services industry in Spain, amounting to EUR 28 million (31 December 2015: EUR 29 million).

The carrying amount of software was EUR 145 million (31 December 2015: EUR 25 million).

Also, the value of the commercial portfolio and customer databases includes, in addition to the impact of the acquisition of companies discussed above, the contract backlog of Enterprise (UK), amounting to EUR 110 million (31 December 2015: EUR 101 million).

“Contracts: Intangibles and Other” also includes other intangibles associated with several concession arrangements in the UK managed outside the scope of IFRIC 12 (Tubelines for management and technical assistance on the London Underground, a Waste Management PFI and Amey Cespa WM with rights to operate in the waste treatment industry), amounting to EUR 87 million (31 December 2015: EUR 87 million).

The cash flow impact of the additions to intangible assets amounted to EUR -8 million (see Note 5.3), an amount lower than the additions recognised in the consolidated statement of financial position, mainly due to investments made in computer software which have not been paid in full.

No impairment losses were recognised or reversed in relation to these assets in 2016.
