A publicly traded partnership structure that passes through income and often appears in energy, infrastructure, and natural-resource investing.
A Master Limited Partnership (MLP) is an unincorporated business entity that combines the tax benefits of a partnership with the liquidity of publicly traded securities. The structure emulates a traditional partnership but allows for investor shares (units) to be traded on public exchanges.
An MLP is certified in a public office, where its agreement and structure are formalized. The certification creates a recognized business entity that operates with distinct rules compared to corporations or traditional partnerships. The formation necessitates adherence to regulatory standards pertinent to publicly traded entities.
MLPs benefit from pass-through taxation, meaning the income earned by the partnership is only taxed once at the investor level, avoiding double taxation that corporations face.
While the general partner has unlimited liability, limited partners enjoy liability protection, only risking their initial investment.
MLPs are prevalent in the natural resources and energy sectors, including oil and gas pipelines. Their structure suits asset-heavy companies requiring stable cash flows to distribute to investors.
Certain real estate operations also employ the MLP structure, leveraging benefits in tax and investment liquidity.
The concept of MLPs began in the 1980s as a method to attract capital into the energy sector. The Tax Reform Act of 1986 and subsequent legislation provided clearer guidelines and benefits, encouraging the growth of MLPs in various sectors.
Regulations have evolved, but primarily the legal framework around MLPs ensures fair trading practices and investor protections, aligned with securities laws.
