Classification Standard

Classification Standard

The Energy MLP Classification Standard (EMCSSM) is the first framework designed to standardize the sector classifications of energy Master Limited Partnerships (MLPs). MLPs are categorized by their primary business activity, with an additional delineation by product or customer made for certain activities to account for structural differences in business risk.
