A corporate rating is a numerical rating of a company’s creditworthiness used to measure the likelihood of default. Corporate ratings are issued by rating agencies and help investors assess the risks associated with investing in corporate bonds. Corporate credit ratings range from best credit quality on the one hand to default or “junk” on the other.
Triple A (AAA) is the highest credit rating, and C or D (depending on the rating agency) is the lowest or junk credit rating.
