Group B Obligor means an Obligor (or its parent or majority owner, as applicable, if such parent or majority owner is a guarantor on the related Contract) that is not a Group A Obligor and that has a short-term rating of at least: (a) “A-2” by Standard & Poor’s or, if such Obligor does not have a short-term rating from Standard & Poor’s, a rating of “BBB+” or better by Standard & Poor’s on such Obligor’s (or, if applicable, its parent’s or its majority owner’s) long-term senior unsecured and uncredit-enhanced debt securities, and (b) “P-2” by Moody’s or, if such Obligor does not have a short-term rating from Moody’s, a rating of “Baal” or better by Moody’s on such Obligor’s (or, if applicable, its parent’s or its majority owner’s) long-term senior unsecured and uncredit-enhanced debt securities; provided, that if an Obligor (or its parent or majority owner, as applicable, if such parent or majority owner is a guarantor on the related Contract) receives a split rating from Standard & Poor’s and Moody’s, then such Obligor (or its parent or majority owner, as applicable) shall be deemed to have the lower of the two ratings; provided, further, that if an Obligor (or its parent or majority owner, as applicable, if such parent or majority owner is a guarantor on the related Contract) is rated by either Standard & Poor’s or Moody’s, but not both, and satisfies either clause (a) or clause (b) above, then such Obligor (or its parent or majority owner, as applicable) shall be deemed to be a Group C Obligor. Notwithstanding the foregoing, any Obligor that is a Subsidiary or Affiliate of an Obligor that satisfies the definition of “Group B Obligor” shall be deemed to be a Group B Obligor and shall be aggregated with the Obligor that satisfies such definition for the purposes of clause (a) of the definition of “Excess Concentration” for such Obligors, unless such deemed Obligor separately satisfies the definition of “Group A Obligor”, “Group B Obligor”, or “Group C Obligor”, in which case such Obligor shall be separately treated as a Group A Obligor, a Group B Obligor or a Group C Obligor, as the case may be, and shall be aggregated and combined for such purposes with any of its Subsidiaries that are Obligors.
