Other income and expenses relate to activities and transactions that are outside the Group’s principal revenue generating activities. Foreign currency exchange gains and losses as well as fair value changes on commodity and foreign currency exchange derivatives entered into as part of the operating business are also presented as other income and expenses. Activities and transactions of a significant or unusual nature are generally adjusted for in the performance measures adjusted EBITDA and adjusted net income used by management (see note 9).
