9. NET FINANCE COSTS
Accounting policy - Net finance costs
The Group’s finance income and finance costs include:
Interest income or expense is recognised using the effective interest method. The 'effective interest rate' is the rate that exactly discounts estimated future cash payments through the expected life of the financial instrument to:
- the gross carrying amount of the financial asset; or
- the amortised cost of the financial liability.
Interest income from loan from related parties and interest on rental in arrears and penalty interest are both calculated using the effective interest rate as described above.
In calculating interest income or expense, the effective interest rate is applied to the gross carrying amount of the asset (when the asset is not credit impaired) or to the amortised cost of the liability. However, for financial assets that have become credit-impaired subsequent to initial recognition, interest income is calculated by applying the effective interest rate to the net amortised cost of the financial asset. If the asset is no longer credit-impaired, then the calculation of interest income reverts to the gross basis.
