Bond Ratings Definitions

There are 10 rating categories from AAA to D for bond ratings. While obligors in rating categories AAA to BBB are considered investment-graded, having more than adequate abilities to meet their financial commitments in a timely fashion, those in rating categories BB to C are believed to contain speculative characteristics in terms of future redemption stability. Obligors in category D are in default.

Rating Definition
AAA An obligor rated 'AAA' has unquestionable capacity to redeem its financial obligations, and holds extremely low investment risks.
AA An obligor rated 'AA' has strong capacity to redeem its financial obligations, although its solvency is relatively weaker than the obligors in the AAA category.
A An obligor rated 'A' has satisfactory capacity to redeem its financial obligations, although it is somewhat more susceptible to the adverse effects of changes in its business and economic environments than the obligors in the AA rating categories.
BBB An obligor rated 'BBB' has moderate capacity to redeem its financial obligations, although its capacity is more likely to be weakened by the adverse effects of changes in its business and economic environments than the obligors in the A category.
BB An obligor rated 'BB' currently has the capacity to redeem its financial obligations. However, it's redemption stability contains speculative characteristics that it cannot be guaranteed in the long-term.
B An obligor rated 'B' is speculative in meeting its financial commitments. Adverse circumstantial changes are likely to impair the obligor's capacity to pay the interests.
CCC An obligor rated 'CCC' is highly speculative in meeting its financial commitments.
CC An obligor rated 'CC' is more speculative than the obligors in the CCC category.
C An obligor rated 'C' has a high default risk and no capacity for redemption.
D An obligor rated 'D' is in default.

※ Ratings between AA and B categories can be designated with a plus (+) or minus (-) sign according to their relative status within each generic rating category.
