"Plant investment grants" refers mainly to investments made in the water and environment sector; this item has decreased in proportion to the amount of depreciation calculated on the fixed assets in question. "VAT, excise and additional taxes" includes 32.1 million euro of VAT (2.2 million euro at 31 December 2015), with an increase of 29.9 million euro due in part to the fact the the yearly advance payment is payed at the end of the month of December, thus reducing the debt exposure as of this date. This item includes, additionally, 83.4 million euro of excise and additonal taxes (8.8 million euro as at 31 December 2015) with an increase of 74.6 million euro. As illustrated in note 23, "Other current assets", this increase must be understood taking into account the factors that regulate financial relations with the Inland Revenue Office, which can generate credit/debit positions with differences that can be significant even between one financial period and another.
