In investment, the bond credit rating assesses the credit worthiness of a corporation's debt issues. It is analogous to credit ratings for individuals and countries. The credit rating is a financial indicator to potential investors of debtsecurities such as bonds. These are assigned by credit rating agencies such as Standard & Poor's and have letter designations such as AAA, B, CC.
Moody's assigns bond credit ratings of Aaa, Aa, A, Baa, Ba, B, Caa, Ca, C, . Standard & Poor's and Fitch assign bond credit ratings of AAA, AA, A, BBB, BB, B, CCC, CC, C, D.
Moody's, S&P and Fitch will all also assign intermediate ratings at levels between AA and B (e.g., BBB+, BBB and BBB-), and may also choose to offer guidance (termed a "credit watch") as to whether it is likely to be upgraded (positive), downgraded (negative) or uncertain (neutral).
