Chemicals and energy group Sasol warned of a dramatic collapse in its 2020 financial performance on Tuesday, confirming that losses for the period would represent a deterioration of more than 100% when compared with results reported for the 2019 financial year. The decline, the company told shareholders in a statement, was driven largely by an impairment charge of about R112-billion across its chemicals and energy portfolios, which had been negatively affected by the deterioration in the long-term macroeconomic outlook.
