Note: Standard & Poor's ratings from A to CCC may be modified by a plus (+) or minus (-) sign to show relative standing within the rating categories. Moddy's uses numerical modifiers 1, 2, and 3 in each category: The modifier 1 indicates that the obligation falls in the higher end of its category; the modifier 2 indicates a mid-range assessment; and the modifier 3 indicates a standing in the lower end of that rating category.
