 imputed promise. For non-hybrid capital instruments, the ‘D’ rating category is used when payments on an obligation are not made on the date due, unless S&P believes that such payments will be made within any stated grace 
 period. However, any stated grace period longer than five business days will be treated as five business days. The ‘D’ rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action and where default on                                                  
 an obligation is a virtual certainty, for example due to automatic stay provisions. A rating on an obligation is lowered to ‘D’ if it is subject to a distressed debt restructuring.                                                                                                             |

Description of S&P’s Municipal Short-Term Note Ratings An S&P U.S. municipal note rating reflects S&P’s opinion about the liquidity factors and market access risks unique to the notes. Notes due in three years or less will likely receive a note rating. Notes with an original maturity of more than three years will most likely receive a long-term debt rating. In determining which type of rating, if any, to assign, S&P’s analysis will review the following considerations:

| • |     | Amortization schedule—the larger the final maturity relative to other maturities, the more likely it will be 
 treated as a note; and                                                                                       |

| • |     | Source of payment—the more dependent the issue is on the market for its refinancing, the more likely it will 
 be treated as a note.                                                                                        |
