What Is a Convertible Bond?
A convertible bond is debt that the holder can convert into shares — a compound instrument that IFRS 9 and IAS 32 split into a liability and an equity element. Here's how it's accounted for.
A convertible bond is a debt instrument that gives the holder the option to convert it into a fixed number of the issuer's ordinary shares, instead of receiving cash redemption. Because it contains both a debt and an equity feature, it is a compound (or hybrid) financial instrument.
Why it is split
IAS 32 requires the issuer to present the two components separately: the obligation to pay interest and principal is a financial liability, while the option to convert into shares is an equity element. This 'split accounting' reflects the substance of the instrument.
How to account for it on issue
- Measure the liability first — the present value of the interest and principal cash flows, discounted at the market rate for similar non-convertible debt.
- The equity element is the residual: total proceeds less the liability component.
- Subsequently, measure the liability at amortised cost using the effective interest rate.
The equity element is not remeasured; the liability unwinds through the effective-interest table until conversion or redemption.
Why examiners like it
It combines present-value discounting, the residual equity calculation and an amortised-cost table — several method marks in one requirement.
