US GAAP specifies how to perform the 10% test; IFRS 9 is less prescriptive
US GAAP contains prescriptive guidance on how to perform the 10% test. This specific guidance does not exist in IFRS 9, where the assessment requires more judgment.
The following are examples.
i. Under US GAAP, if the original debt or the new debt has a floating interest rate, then the variable rate in effect at the date of the modification is used to calculate the cash flows of the instrument. Under IFRS 9, in our view, the following approaches may also be acceptable, as long as the selected approach is applied consistently (in each case the contractual rate is used for the remaining coupons of the original debt for which interest rate has been determined):
- use the relevant benchmark interest rate determined for the current interest accrual period according to the original terms of the debt instrument; or
- use the relevant benchmark interest rates for the original remaining term based on the relevant forward interest rate curve and the relevant benchmark interest rates for the new term of the instrument based on the relevant forward interest rate curve.
ii. Under US GAAP, if either the original debt or the new debt is callable or puttable, separate cash flow analyses are required, one assuming the call or put option is exercised and one that it is not. The analysis that generates a smaller change in cash flows forms the basis for determining whether the 10% test is met. Under IFRS 9, assuming the prepayment option is not required to be bifurcated, in our view, other approaches could also be considered to determine cash flows, including either of the following:
- calculate probability-weighted cash flows considering different scenarios, including the exercise or non-exercise of the call or put options; or
- use the outcome of the most likely scenario.
iii. Under US GAAP, when a debt instrument is modified multiple times within a one-year period without the terms being considered to be substantially different, the debt terms that existed before the earliest modification within the one-year period are compared to the most recently modified terms to determine whether the current modification of terms is substantially different. IFRS 9 provides no specific guidance in such a scenario and each modification is assessed separately.
