Definition

Notching

The process of adjusting a rating downward from the issuer level to reflect the additional risk of subordinated instruments.

Example

How it works in practice

A European insurer has an overall credit rating of A from a major rating agency. However, its newly issued subordinated Tier 2 bond receives a BBB+ rating, two notches below the issuer rating. The lower rating reflects the bond's junior position in the capital structure and its coupon deferral features, which increase the risk of non-payment relative to the insurer's senior obligations.
