                                  AAA | 
                                  The ability to repay debt is very high. Stability is at the highest level. |

                                  AA+/AA/AA- | 
                                  The ability to repay debt is high. It carries slightly more risk than AAA bonds, but stability is at a high level. |

                                    The ability to repay debt is sufficient, and stability is at an upper-middle level; however, it is somewhat susceptible to the effects of
                                    adverse economic conditions and environmental factors compared to higher ratings.

                                  BBB+/BBB/BBB- | 
                                  
                                    Stability is moderate. Current debt repayment ability is satisfactory, but there is a possibility that future repayment capacity may decline due
                                    to adverse economic conditions and environmental factors compared to higher ratings.

                                    The likelihood of default occurring in the near future is relatively low, but there is uncertainty regarding future safety, which introduces
                                    speculative elements.

                                    If the management environment deteriorates, the likelihood of default increases, introducing speculative elements and raising the level of risk.

                                  CCC+/CCC/CCC- | 
                                  There is a possibility of default at present, which results in a high level of risk and many speculative elements. |

                                  The likelihood of default is quite high at present, resulting in a very high level of risk. |

                                  Bankruptcy filing or similar situations may occur, but debt repayment is being made on a limited basis. |

                            * Among the aforementioned ratings, Moody’s uses 1, 2, and 3, while S&P adds + and - to indicate the relative ranking within the same rating category.
