- Usually the second- or third-highest rating that a rating agency assigns to a security or carrier. This rating signifies that there is a relatively low risk of default because the issuer or carrier is fairly stable. Investors and policyholders are therefore taking very little risk with these companies.
The ratings assigned by the various ratings agencies are based primarily upon the insurer's or issuer's creditworthiness. This rating can therefore be interpreted as a direct measure of the probability of default. However, credit stability and priority of payment are also factored into the rating.
