SPPI assessment of loans with sustainability-linked or other ESG-contingent interest rate features

A growing share of corporate lending includes a contractual interest rate step-up or step-down contingent on the borrower meeting ESG performance targets, and the bank must assess whether this contingent feature is consistent with a basic lending arrangement so the loan can still pass the solely-payments-of-principal-and-interest (SPPI) test and qualify for amortized cost or FVOCI, rather than being swept into FVTPL for the entire instrument. Getting this wrong in either direction, waving through a feature that could have more than a de minimis cash flow effect, or over-conservatively FVTPL-ing loans with genuinely trivial adjustments, misstates interest income recognition and introduces P&L volatility that need not exist, and the population of these loans is growing quickly.

Has the maximum possible effect on contractual cash flows of the sustainability-linked rate adjustment been quantified under all reasonably possible scenarios, not just the expected case? Does that maximum effect remain no more than de minimis compared to a benchmark instrument without the ESG feature, and is the feature genuine (contingent on an uncertain future event) rather than designed to circumvent SPPI? If the potential effect could be more than de minimis, has the entire instrument been classified at FVTPL rather than amortized cost or FVOCI?

1. Read the loan's sustainability-linked mechanism in full: what target(s) trigger the adjustment, the size of the rate step-up/step-down, and the frequency of testing.
2. Quantify the maximum possible effect on contractual cash flows of the adjustment mechanism under all reasonably possible scenarios (not just the expected or base case).
3. Compare that maximum effect to the cash flows of a benchmark instrument with the same terms but without the ESG feature.
4. If the difference is no more than de minimis in every reasonably possible scenario, and the feature is genuine (contingent on an uncertain future event, not designed to circumvent SPPI), the loan can still be assessed on the SPPI outcome of its other terms, proceed to classify at amortized cost or FVOCI based on the business model.
5. If the potential effect could be more than de minimis, or the feature is not genuine, classify the entire instrument at FVTPL.
6. Reassess if the sustainability-linked targets or adjustment mechanics are subsequently renegotiated.

Quantify the maximum possible cash flow impact of the ESG-linked rate adjustment (the step-up/step-down in basis points multiplied by the outstanding balance and remaining term) under reasonably possible scenarios, and compare it against the cash flows of a benchmark loan without the feature to determine whether the difference is de minimis, documenting the analysis contemporaneously. If classified at amortized cost or FVOCI, measure interest income using the effective interest method based on the most likely outcome of the contingent adjustment at inception, and revise the estimate (adjusting the carrying amount through profit or loss) if the probability of meeting the ESG target changes materially. If classified at FVTPL because the feature fails SPPI, remeasure the entire instrument to fair value each period through profit or loss.

Disclose: (1) the nature and extent of sustainability-linked or other ESG-contingent lending in the portfolio; (2) the judgment applied in concluding whether the contingent features affect SPPI classification, including the quantitative de minimis analysis approach; (3) the carrying amount of any such loans measured at FVTPL solely because of a failed SPPI assessment, separately from other FVTPL loans; (4) accounting policy for sustainability-linked loan features; (5) any changes in classification arising from renegotiated ESG targets or mechanics during the period.

• Assuming all sustainability-linked loans automatically pass SPPI without quantifying the potential cash flow impact of the rate adjustment mechanism under reasonably possible scenarios
• treating a genuinely de minimis ESG feature as disqualifying the loan from amortized cost classification out of excess caution, unnecessarily inflating FVTPL volumes and P&

• not documenting the quantitative analysis contemporaneously, making the conclusion difficult to support on audit.
