The S&P MLP Index is designed to provide exposure to leading partnerships that trade on major U.S. exchanges. The index includes both master limited partnerships (MLPs) and publicly traded limited liability companies (LLCs), which have a similar legal structure to MLPs and share the same tax benefits. As the vast majority of traded partnerships have operations in the oil and gas industries, the S&P MLP Index follows the Global Industry Classification Standard (GICS®) and focuses on companies in the GICS Energy Sector and the GICS Gas Utilities Industry
