Interest income relates to interest earned from financial assets (cash and cash equivalents and loans) measured at amortised cost. Interest is recognised on a time proportionate basis, taking into account the principal amount outstanding and the effective interest rate.

The increase in interest income for Company is due to the loans granted to Openserve in the prior year as part of the carve-out. The increase in dividend received is mainly due to dividends received from BCX of R2 436 million.

R2 650 million of the dividends declared by BCX and Gyro are non-cash and were net settled through the entities' intercompany accounts.
