Investor FAQ

What is NuStar Energy L.P.’s trading symbol and on which exchange is it listed?

NuStar Energy L.P. (NuStar) is a publicly traded Master Limited Partnership that trades on the New York Stock Exchange (NYSE) under the symbol “NS.”

What is a Master Limited Partnership (MLP)?

MLPs are limited partnerships that are traded on public stock exchanges. An ownership interest in an MLP is called a “unit,” and owners of MLP units are known as “unitholders.”

Who invests in MLP units?

In general, MLPs pay available cash to unitholders through quarterly distributions. In addition, MLPs are tax-advantaged investments, as unitholders benefit from the fact that MLPs are not typically subject to the entity level federal income taxes of a corporation. Unitholders pay tax on their proportionate share of the MLPs income, which may be reduced by their share of tax deductions.

What are the tax implications of ownership?

While MLPs do not pay any federal income tax, each unitholder is required to report their share of partnership income, gains, losses, deductions and credits on their income tax return. Each year, an MLP provides each unitholder with this information on Schedule K-1 for the previous fiscal year. The K-1 is typically available online in early March and mailed shortly thereafter. A press release is issued notifying the investor base of their K-1 availability.
