The increase in staff costs including capitalised costs, and on a like-for-like basis, stands at 6,025 thousand euros and is substantially determined by the growth recorded by ACEA, partially mitigated by the reduction in the cost incurred by the business areas. The Industrial Area is broken down as follows:

€ thousand 31.12.2012 31.12.2011 Increase/ (Decrease) Increase/ (decrease) %
Networks 86,565 91,118 (4,553) -5.0%

Total 354,115 345,265 8,850 2.6%

Staff costs for the period were mainly affected by the increase in average per capita costs resulting from the renewal of employment contracts, remuneration policy and certain management-related factors such as overtime and availability.

In addition, the change recorded by ACEA was, amongst other things, affected by the reintegration of employees from the business unit rented to Marco Polo beginning on 1 January 2012, the contract on which expired. The cost relating to this phenomenon was approximately 6.6 million euros. A further effect came from the change made by the Parent Company to centralise certain departments initially allocated to the individual operating companies, which led to an increase in the average ACEA workforce. The increase in this cost for the Overseas water services area is influenced by the unfavourable exchange rate with the local currency.

With regard to capitalised costs, note the increase of 5,191 thousand euros (on a like-for-like basis), largely recorded by the water companies and particularly ACEA Ato2.
