Group A Obligor means any Obligor (or its parent or majority owner, as applicable, if such Obligor is not rated) with a short-term rating of at least: (a) “A-1” by S&P, or if such Obligor does not have a short-term rating from S&P, a rating of “A+” or better by S&P on such Obligor’s, its parent’s, or its majority owner’s (as applicable) long-term senior unsecured and uncredit-enhanced debt securities, or (b) “P-1” by Moody’s, or if such Obligor does not have a short-term rating from Moody’s, “Al” or better by Moody’s on such Obligor’s, its parent’s or its majority owner’s (as applicable) long-term senior unsecured and uncredit-enhanced debt securities; provided, that if an Obligor (or its parent or majority owner, as applicable, if such Obligor is not rated) receives a split rating from S&P and Moody’s, then such Obligor (or its parent or majority owner, as applicable) shall be deemed to have only the lower of the two rating for the purpose of determining whether such rating satisfies clauses (a) or (b) above. Notwithstanding the foregoing, any Obligor that is a Subsidiary of an Obligor that satisfies the definition of “Group A Obligor” shall be deemed to be a Group A Obligor and shall be aggregated with the Obligor that satisfies such definition for the purposes of determining the “Concentration Reserve Percentage”, the “Concentration Reserve” and 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.
