Finance charges relate to interest expense on financial liabilities measured at amortised cost.

Finance charges on local and foreign debt decreased from R1 570 million in March 2020 to R1 251 million in March 2021, mainly due to reduced interest rates as a result of the COVID-19 pandemic. Included in finance charges, as at 31 March 2021, is an amount of R29 million relating to interest on the SARS liability.
