What are the bond ratings AA- AA?

Bond ratings are divided into AAA, AA, A, BBB, BB, B, CCC, CC and C. In addition to these ratings, the "+"and "-"symbols are often used for fine adjustment, indicating that they are slightly higher or lower than the original rating. AAA generally represents strong repayment ability and low default risk, while C is the opposite.
