Financial income and expenses mainly comprise interest accrued on the Group’s financial assets and liabilities during the year (see note 18). Net foreign exchange differences are principally due to fluctuations in the currencies with which the Group operates (see note 25) between the time when income, expenses, acquisitions or disposals of assets are recognized and when the corresponding assets or liabilities are realized or settled under applicable accounting principles.
