## Question put to the AI subject

Does the Consumer Duty require firms to quantify non-monetary benefits in their fair value assessment, and what level of analysis does the FCA expect?

## AI subject's verbatim answer

the FCA does not mandate a single financial methodology for non-monetary items, but it does expect firms to go beyond qualitative description and provide substantiated comparisons.

## Verbatim regulator text contradicting the answer

> From FCA guidance: 'The FCA does not expect firms to quantify non-monetary costs and benefits as part of its fair value assessment process, but firms should undertake some form of qualitative assessment.'

_Section anchor:_ FG22/5 — Fair value assessment: no quantification requirement for non-monetary benefits

## Failure mode

**`inference_drift`** — Inference drift — the AI inferred a conclusion the regulator's text does not warrant, often by combining unrelated provisions.
