A credit rating is an evaluation of the credit worthiness of a debtor (a business (company) or a government) predicting the debtor's ability to pay back the debt; it thus forecasts implicitly the likelihood of the debtor's default.
The credit rating represents the evaluation of the credit rating agency of qualitative and quantitative information for the debtor; including non-public information obtained by the credit rating agencies' analysts.
