Understanding Limited Partnership Units (LPUs): Definition and Functionality
Discover what a limited partnership unit (LPU) is and how it operates within a publicly traded limited partnership or master limited partnership (MLP).
What Exactly Is a Limited Partnership Unit (LPU)?
A Limited Partnership Unit, commonly known as an LPU, represents a stake of ownership in a publicly traded limited partnership, often referred to as a master limited partnership (MLP). Holding an LPU entitles the investor to a share of the income generated by the partnership’s operations. These units are also called master limited partnership units or limited partner units.
How Does a Limited Partnership Unit Function?
An LPU is essentially a share certificate that signifies ownership in an MLP, which is a limited partnership listed on a public exchange. MLPs typically distribute most of their available cash flow—after covering maintenance capital expenses—to unit holders as dividends or cash distributions.
One major advantage of LPUs for investors is the tax benefit: MLPs avoid the double taxation commonly associated with corporations. Instead, income is taxed only at the unit holder’s level, bypassing corporate taxes and often resulting in higher cash distributions to investors.
Important Tax Note
Limited partnerships are considered flow-through entities for tax purposes, meaning they do not pay taxes themselves. Instead, investors report their proportional share of the partnership’s profits or losses on their personal tax returns, regardless of whether cash distributions were received.
Liability Considerations for Limited Partnership Units
Investors’ financial risk in LPUs is limited to their original capital investment, protecting them from further liability related to the partnership’s debts. Each year, limited partnerships typically provide unit holders with IRS Schedule K-1 forms to report income and losses.
While LPUs generally pay quarterly cash distributions, these payments are not guaranteed. Nevertheless, investors must pay taxes on their share of the partnership’s income even if no distribution is made.
Advantages of Investing in Limited Partnership Units
Besides the tax efficiencies, LPUs offer enhanced liquidity since they are publicly traded, unlike traditional private partnerships. Many LPUs are eligible for investment in retirement accounts such as IRAs and RRSPs. These units are often concentrated in sectors like real estate, commodities, and natural resources including oil, natural gas, timber, and petroleum.
Special “at-risk” rules apply to limited partners, restricting losses claimed to the amount actually invested, preventing investors from deducting losses beyond their at-risk capital.
If an investor’s adjusted cost base (ACB) for LPUs becomes negative, it triggers a deemed capital gain, resetting the ACB to zero. Future positive ACBs may allow investors to recognize capital losses to offset prior gains, providing potential tax recovery.
Key Points to Remember
- Limited Partnership Units (LPUs) represent ownership in publicly traded limited partnerships or MLPs.
- LPUs benefit from pass-through taxation, avoiding double taxation at the corporate level.
- Investor liability is limited to their initial capital invested in the partnership.
