Frequently asked questions
We won’t ask you to provide specific asset security to secure your overdraft. For corporate borrowers, director guarantees may be required.
If you choose to offer security for your business overdraft, you will typically pay a lower interest rate on the funds you draw down than if you choose the unsecured business overdraft option. Bear in mind that the interest rate is lower because we secure the overdraft using a pre-agreed asset, which we can recover against if you are unable to repay the overdraft.
A line fee is charged monthly based on the total limit. The monthly charge is calculated using the line fee annual percentage rate, total limit, and number of days to arrive at the monthly amount.
For example, let’s say the line fee is 1.50% p.a., the limit of your overdraft is $10,000 and the month has 31 days.
The line fee is calculated as:
(1.50% of $10,000)/365x31 days = $12.73 per month.
Conditional offers are calculated periodically based on your financial information at a certain point in time. If your financial situation changes, this may affect your borrowing power, meaning that you may no longer have a conditional approval.
