## Question put to the AI subject

What was the immediate impact of the October 2024 IMF surcharge reform on the number of countries paying surcharges as of November 1, 2024, and what is the projected count of surcharge-paying countries through fiscal year 2026?

## AI subject's verbatim answer

Before reform: 19 IMF member countries were paying surcharges. After 1 November 2024: 11 countries continue to pay surcharges. Net: 8 countries are immediately released from surcharge obligations

## Verbatim regulator text contradicting the answer

> The number of surcharge payers is expected to decline from 20 to 13 countries (in FY2026).

## Failure mode

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