A-/A3

DEFINITION of 'A-/A3'

This is generally the third- or fourth-highest rating that a rating agency assigns to a security or insurance carrier. It is often the lowest investment-grade rating, but it signifies that the issuer is fairly stable with relatively low default risk.

BREAKING DOWN 'A-/A3'

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.
