Mistaken idea “A forecast overlay can be chosen as a plug”

Mistaken reasoning: This mistake selects a credit loss adjustment to reach a desired allowance or earnings amount.

Updated Sep 11, 2026 Review due Dec 11, 2026

Why this is mistaken

An adjustment needs evidence that connects a dated condition or forecast to the pool's expected cash shortfall. A target allowance or earnings result cannot supply direction, magnitude, horizon, or reversion.

Where to watch

When this mistake may appear

  • The historical loss rate does not produce the allowance that management expects.
Check your work

Your work may contain this mistake if:

  • Adds a round adjustment without a dated driver, pool link, overlap check, forecast horizon, or reversion method.
