Incremental Borrowing Rate Frequently Asked Questions

With the current environment in a constant state of change it's important to ensure your Incremental Borrowing Rate (IBR) is up-to-date and correct, especially for modifications. This will help avoid any compliance issues or balance sheet inaccuracies down the track.

If you are unsure of why an IBR is important or how to calculate it, our friends at Deloitte have put together some handy FAQs covering the what, why, when and how of IBR.

What is an Incremental Borrowing Rate?

IBR is defined as the rate of interest that a lessee would have to pay to borrow, over a similar term and with a similar security, the funds necessary to obtain an asset of a similar value to the right-of-use asset in a similar economic environment.

Why do I need to use the Incremental Borrowing Rate?

IFRS 16/AASB 16 requires lessees to recognise assets and liabilities for all leases, excluding short-term and low-value leases. The lease liability is measured as the present value of future lease payments, discounted using the interest rate implicit in the lease if this can be readily determined or, if not, using its IBR.

IFRS 16/AASB 16 requires the discount rate applied to leases to take into account the credit profile of the lessee, the lease length, the nature and quality of any collateral and the underlying economic environment at the assessment date. Since the interest rate implicit in the lease requires knowledge of the asset fair value, residual value and any associated costs, using the IBR of the lease is often the favoured approach among practitioners.

When do I need to update my Incremental Borrowing Rate?

All newly incepted leases must have an updated IBR applied to them. Entities are required to update their IBR for an existing lease liability whenever there is a change in the lease terms (a modification) or if the lessee is reasonably certain to exercise an option to purchase the underlying leased asset.

Additionally, a lessee should use a revised IBR for assessing floating rate leases when there is a change to the underlying floating rate.
