## Formula for Eligible Borrowing Cost
```
Borrowing Cost Eligible for Capitalisation
= Actual Borrowing Cost during Construction Period
LESS: Income earned on Temporary Investment of idle loan funds
```

## Why Deduct Temporary Investment Income?
When a loan is drawn but funds are not yet fully deployed (temporarily idle), the entity may invest those funds. Income earned on such investment reduces the net cost of the borrowing — the asset is effectively partially self-financing during that period.

## Period of Capitalisation
| Event | Effect |
|---|---|
| Expenditure on asset begins AND borrowing costs are being incurred AND preparatory activities are in progress | Capitalisation starts |
| Substantially all activities to prepare the asset are complete | Capitalisation stops |
| Active development suspended for extended period | Suspend capitalisation |
> Capitalisation must stop at completion — even if the loan continues.
