Ratings are established according to a predetermined scale. The scale is expressed in letters of the alphabet and varies according to agencies.
Impact on accounts
The downgrading or upgrading of a rating has a direct impact on the evolution of the company's activity. Going from "AA" (the equivalent of 17 to 19 out of 20) to "A" (14 to 16 out of 20) can cause a significant fall of the company's activity volume. Every time a rating is downgraded, the cost of its resources increases, and after a certain number of operations, the rating is definitely suspended.
Impact on the stock exchange rates
The attribution of a grade does not represent a suggestion to purchase or sell, but it has a considerable effect on the company's image. Thus, it is frequent to see a stock drop after a bad rating or a downgrading (and vice versa). However, rating agencies often react with some delay, which limits the negative impact. Thus, difficulties are already taken into account by the market and integrated in the rates.
By way of example, the charts below represent the rating scales concerning companies' financial growth used by AM Best and S & P respectively:
