A+/A1
It is one of the top ratings that a ratings agency allots to an issuer or insurer. This rating indicates that the security or carrier has steady financial backing and plenty cash reserves. The risk of failure to pay for investors or policyholders is extremely low.
The ratings allotted by the diverse ratings agencies are on the basis of the insurer's or issuer's creditworthiness. This rating can thus be considered as a direct measure of the probability of default. Though, credit stability and priority of payment are also considered into the rating.
