any of you have probably heard of master limited partnerships (MLPs), but our experi-ence is that few management accountants have anything but a cursory knowledge of these investment vehicles. We suspect, too, that even many finance personnel have little more than a vague understanding of the intricacies of MLPs.

In an effort to demystify them as an investment vehicle, we have endeavored to provide a descriptive account of MLPs: what they are, how they are organized and managed, how these entities (and their unit-holders) are taxed for U.S. income tax purposes, the primary lines of business in which MLPs operate, and the relevant risks and benefits of invest-ing in these vehicles. Given the broadened role of accountinvest-ing and the blurring of the lines of demarcation between account-ing and finance functions, this information should be of inter-est to a wide array of management accounting professionals— both as a personal investment option and from the standpoint of the management accountant’s role as a member of an orga-nization’s finance team.

Legal Structure of MLPs

An MLP is the more common term used to describe a pub-licly traded partnership (PTP). An MLP can be organized ei-ther as a limited partnership (LP) or as a limited liability

Master Limited Partnerships:

A Primer

EXECUTIVE SUMMARY

Master limited partnerships (MLPs) are complex corporate structures. Management accountants who are considering them as investment options—whether for their own per-sonal investment or in their role as a member of the finance team—should ensure they have a thorough under-standing of MLPs so they can make informed investment decisions.

pany (LLC) choosing partnership taxation. Shares of ownership in these entities are referred to as “units,” which are traded on a stock exchange, such as the New York Stock Exchange (NYSE), NASDAQ, or one of the regional exchanges in the United States. Owners of units are referred to as “unit-holders.”

To qualify for treatment as a partnership for U.S. federal income tax purposes, at least 90% of the part-nership’s gross income must be derived from “quali-fying income.” As defined in §7704(d) of the U.S. In-ternal Revenue Code (IRC), qualifying income includes:

◆ Interest, dividends, and capital gains;

◆ Rental income and capital gain from the sale of real estate;

◆ Income and capital gains derived from exploration, development and production, mining, gathering and processing, refining, compression, transportation, storage, marketing, distribution (but not retail sales, except for propane) of minerals, fertilizer, geother-mal energy, timber, industrial carbon dioxide, bio-fuel, crude oil, gasoline, and other petroleum products;

◆ Income from commodity investment or futures, forwards, or options with commodity as underlying assets; and

◆ Capital gains from the sale of assets used to generate the above income.

Because ownership units in MLPs are publicly traded, they offer the liquidity of corporate invest-ments, such as stocks and bonds. Since they are part-nerships, however, MLPs are not treated as separate en-tities for federal (and, in most cases, state) income tax purposes. Instead, MLPs are considered “pass-through” entities, which means that they pay no corporate taxes and that their income passes through to individual part-ners (unit-holders) who pay income taxes at their indi-vidual levels. MLPs also pass through their depreciation and depletion deductions to their unit-holders. Most MLPs provide regular cash distributions, although some can also use the cash for their own growth opportunities (e.g., by acquiring additional pipelines and/or storage facilities).

There are approximately 120 MLPs traded in the

United States, with a total market value of approxi-mately $420 billion.1_{As shown in Figure 1, the}

ma-jority of these entities are in the energy (oil and gas) sector. Financial analysts and corporate executives of-ten separate the energy supply chain into upstream business (exploration and production), midstream business (transportation of oil and gas), and down-stream business (delivery of final refined products, such as diesel and gasoline, to customers). As Figure 1 shows, most MLPs operate in the midstream sector of the oil and gas supply chain. Table 1 provides a list of the five largest MLPs, in terms of market value, as of the date of this writing.

Ownership Structure of MLPs

Each MLP has one general partner (GP) that actively manages the businesses and assets of the partnership in conjunction with the board of directors. In most cases, the general partner is completely controlled by the MLP’s founding entity (which could be a group of part-ners, a single individual, a private company, a publicly traded company, or even another MLP).

Figures 2– 4 show the fictionalized organizational structures of different types of MLPs. All three are based on actual companies. Figure 2 illustrates the orga-nizational structure ABC Partners LP, an MLP with a general partner that is a private company. Figure 3 pre-sents Pipeline Midstream Energy Partners LP, an MLP with a general partner that is a publicly traded corpora-tion also listed on the NYSE. Figure 4 shows the orga-nizational structure of Pipeline MLP LP, which has an-other MLP as its general partner.

In addition to a general partner, there also can be many limited partners (LP) within any MLP. These are investors who provide capital but do not run the busi-ness or control the MLP’s assets. Limited partners are entitled to a cash distribution generated from the MLP’s operations and can trade their partnership units on a public exchange, similar to what investors in corpo-rate stocks and bonds can do.

Cash Distributions and Incentive Distribution Rights

An MLP’s general partner typically is compensated in two ways. First, most general partners also hold LP units in the partnership, which entitles them to the same cash distributions as other limited partners. Sec-ond, the general partner may also receive incentive dis-tribution rights (IDRs), which are extra cash distribu-tions based on a predetermined performance formula. Different MLPs have different incentive distribution rights. For example, Sunoco Logistics Partners LP (NYSE: SXL), a crude oil and gasoline pipeline MLP, has an IDR arrangement with its general partner, En-ergy Transfer Partners, LP (NYSE: ETP), illustrated in Table 2.

When an MLP intends to go public and files its prospectus with the U.S. Securities & Exchange Com-mission (SEC), it includes a statement regarding the in-tention to distribute a specified minimum level of cash distributions on a quarterly basis. This amount is re-ferred to as the minimum quarterly distribution (MQD). The split of the total quarterly cash distribu-tion between the general partner and the limited part-ners is specified in the IDR provision of the partpart-nership agreement. As Table 2 shows, to motivate the general partner to increase cash distributions to the limited partners, the percentage split to the general partner

in-creases as the total cash distribution to the limited part-ners generally increases. As such, investors should be cognizant of the specific terms of the incentive distribu-tion rights before investing in a particular MLP.

Further discussion of Table 2 may be instructive in terms of illustrating how incentive distribution rights work. Table 2 shows that for the minimum quarterly distribution, the limited partners in Sunoco Logistics Partners would receive $0.45 per unit (i.e., per share) held. The specified split of the minimum quarterly dis-tribution for SLX is 2% (GP) and 98% (LPs). Thus, $0.45 per LP unit represents 98% of the combined LP and GP distribution per LP unit. This implies that the aggregate cash distribution per unit would be $0.4592 (i.e., $0.45/$0.98). The $0.0092 per-unit difference be-tween $0.4592 and $0.45 is the per-LP-unit cash distrib-ution to the general partner. As of the second quarter of 2013, SXL had 104.3 million LP units outstanding. If each of these units received a $0.45 cash distribution, the cash distribution to the general partner would have been approximately $959,560 (i.e., $0.0092/unit × 104.3 million LP units).

In actuality, in the second quarter of 2013, SXL an-nounced a cash distribution of $0.60 per LP unit. Based on the IDR plan reflected in Table 2, the per-unit cash distribution for the limited partners and the general partner (per LP unit) would be as shown in Table 3.

*Energy Transfer Partners, LP (NYSE: ETP).

With 104.3 million LP units outstanding, the general partner’s total cash distribution in the second quarter of 2013 would have been $2.086 million (i.e., $0.02/unit × 104.3 million units). At this time, Energy Transfer Part-ners (the GP) also owned 32.4% of the LP units in SXL, which would have provided an additional $20.27592 million (i.e., 104,300,000 units × 32.4% × $0.60/unit). In total, therefore, the 2013 second quarter cash distribution from SXL to Energy Transfer Partners would have been $22.30192 million ($20,275,920 from its holding of LP units and $2,086,000 from the IDR agreement).

The idea of incentive distribution rights is to encour-age the general partner to take actions and make deci-sions that maximize cash distribution to holders of LP units. But the higher the incentive distribution right, the less cash there is to pay LP unit-holders. Also, a higher incentive distribution right may also mean less cash for the MLP to service its debt, make acquisitions, and expand. Therefore, the existence and structure of an IDR for an MLP should be an important considera-tion for investors. Because the general partner can be a publicly traded MLP itself, investors could take advan-tage of a high IDR arrangement by investing in the GP entity instead of in the LP units of the MLP. In recent years, several MLPs have voluntarily changed their IDR formula in order to attract investors. For example, Enterprise Products Partners LP and its general partner agreed to eliminate its incentive distribution right after

founder Dan Duncan passed away in 2010.

Tax Considerations

As noted, MLPs are considered pass-through entities for tax purposes, which means they pay no income taxes. Instead, the annual income of the MLP is passed through to unit-holders each year via information re-ported to investors on Schedule K-1 (Form 1065). Unit-holders enter their share of the MLP’s income, gains, deductions, losses, and credits on their own tax returns. Therefore, income taxes are paid at each individual in-vestor’s marginal rate.

Table 4 presents a hypothetical example of the net-of-tax cash flow for a corporate shareholder compared to an MLP unit-holder. As the table shows, certain vestors can secure tax benefits (depending on the in-vestor’s and the corporation’s marginal tax rates at both the federal and state level) by investing in an MLP rather than a taxable corporate entity’s stocks or bonds. In this example, the after-tax cash flow to the investor is greater for the unit-holder of the MLP.

For most MLPs, the annual cash distribution to unit-holders is usually larger than the net income generated by the partnership. The difference between cash distri-bution and net income arises principally from deprecia-tion and depledeprecia-tion charges. Unit-holders of an MLP pay tax only on the net income of the entity, regardless of cash received. Note, however, that the unit-holder’s tax basis in the investment in an MLP is decreased by the

excess (if any) of the cash distribution for the year di-vided by the MLP’s net income for the year. Once the investor’s tax basis in the MLP reaches zero, the in-vestor must pay ordinary income tax on the whole cash distribution received. When MLP shares are sold, the difference between the tax basis at time of sale and the original purchase price of the investment is taxed as or-dinary income, while the difference between the origi-nal purchase price and sale price at disposition is taxed

as capital gain. Table 5 provides an example of the intri-cacies of tax-related effects associated with disposal of units by a unit-holder.

When investors hold MLP units in a retirement ac-count, such as an IRA or a Roth IRA, unrelated busi-ness income tax (UBIT) consequences should be evalu-ated. According to the U.S. Internal Revenue Code (IRC), UBIT is the tax associated with an activity en-gaged in by a tax-exempt entity (including an IRA or

Year 1: 100 units of an MLP purchased at $60 per unit

Tax Basis at Acquisition Date $6,000

In year 1, a $600 cash distribution is received by the unit-holder. Schedule K-1 (Form 1065) for the unit-holder shows $120 in net income and $480 in pass-through deductions for the MLP.

Income tax on net income (40%, assumed) $48

401(k) retirement plan) that is not related to the exempt purpose of that entity.2_{Because MLPs are}

pass-through entities, the tax-exempt retirement account (i.e., the investor’s IRA or 401(k) plan) directly earns an allocable share of an MLP’s business income (the in-come of which is considered unrelated to the exempt purpose of the account) rather than usual in-vestment interest or dividends (related tax-exempt purpose) of the account. Therefore, net income from MLP units held in an IRA or 401(k) account is taxed. The account custodian for the IRA should file a sepa-rate tax return and pay tax from the account’s funds.

Some financial advisors suggest that the UBIT should not discourage investors from investing their re-tirement fund in an MLP because the UBIT arises only when total net income is more than $1,000 in a year. The tax is levied on net income (i.e., excluding depre-ciation and depletion charges), not on the cash distribu-tion the investor receives. Put another way, pass-through depreciation and other noncash deductions (such as depletion) are not taxed. For most MLPs each year, the amount of noncash deductions passed through to unit-holders is generally between 80%-90% of the net income reported by the MLP. For purposes of de-termining whether the provisions of the UBIT apply, the share of taxable net income allocated to the unit-holder would be below the $1,000 critical value.

An alternative view is that investing IRA or 401(k) funds in MLPs should not be encouraged because most cash distributions from MLPs are already tax deferred, as illustrated in the hypothetical example presented in Table 5. Putting tax-deferred assets in a tax-deferred re-tirement account would therefore not likely maximize an investor’s tax benefit. A better tax strategy would be to invest funds from a regular (i.e., a taxable) account in MLP units and to invest nontax-deferred assets (such as regular stocks, bonds, or equity mutual funds) in tax-deferred retirement accounts.

For example, suppose you have $5,000 in a retire-ment account that is tax deferred and $5,000 in a regu-lar stock brokerage account that is not tax deferred. You normally would not want to invest funds from the tax-deferred retirement account in MLP units while invest-ing your remaininvest-ing funds ($5,000) in a regular mutual fund, such as an S&P 500 index fund. This is because

most MLP cash distributions are already tax deferred, while capital gains and dividends associated with the in-vestment in the S&P 500 index fund would not be tax deferred. To defer the tax on capital gains and dividend income received, you would probably want to buy a regular stock mutual fund, such as an S&P 500 index fund, with funds from a tax-deferred retirement ac-count. Rather than investing the remaining $5,000 in a taxable account, the savvy investor should consider an investment in an MLP since most of the cash distribu-tions are tax deferred, as shown in Table 5. This invest-ment strategy would maximize your tax advantages of the total $10,000. Of course, risk considerations would also factor into the decision of how the available capital is invested.

Purchasing MLP Shares

For most investors, the most cost-efficient way to invest in the U.S. equity market is to buy a mutual fund, exchange-traded fund (ETF), or exchange-traded note (ETN). Investors in these instruments can achieve tar-geted levels of diversification at a relatively low cost. There are MLP-based ETFs. The JP Morgan Alerian MLP ETN (NYSE Arca: AMJ) is the largest and most popular, and the ALPS Alerian MLP ETF (NYSE: AMLP) and Oppenheimer SteelPath MLP Income Fund Class A shares (NYSE: MLPDX) are also popular choices.3

On the other hand, investing in mutual funds that hold MLPs provides two primary benefits to investors: (1) Instead of having to deal with Form K-1 each year, investors would get a familiar Form 1099 from the fund, and (2) investors are able to invest retirement-account money into these funds without worrying about UBIT.

MLP Businesses

Before investing in an MLP, investors should have a firm understanding of the business sector in which the MLP operates. As indicated in Figure 1, MLPs are mostly involved with energy products—primarily crude oil, natural gas, refined products, and coal. Yet the net income and distributable cash flows of most MLPs are not related to energy product prices. Because most MLPs are in the midstream sector of the energy supply chain, they generate revenue based on volume

processed or shipped.

Natural Gas Processing and Natural Gas Liquid Fractionation

Natural gas used by consumers is primarily methane, while raw natural gas from underground sources con-tains other hydrocarbons, including ethane, propane, butane, and pentanes. These associated hydrocarbons are called natural gas liquid (NGL). In addition, raw natural gas may also contain water vapor, hydrogen sul-fide, carbon dioxide, helium, nitrogen, and other com-ponents. MLPs, such as Enterprise Products Partners, LP, own natural gas processing plants that separate methane (also called dry natural gas) from natural gas liquid and other components. This is known as natural gas processing. Dry natural gas is injected into a pipeline and shipped to natural gas utilities, storage facilities, or power plants. In the next step, natural gas liquid must be further decomposed into ethane, propane, butane, and pentanes before it can be sold for a variety of different uses, including oil recovery in oil wells, materials for refineries or petrochemical plants, and as a source of energy. This process is called NGL fractionation.

Product Pipelines

Some MLPs own pipelines that carry dry natural gas, crude oil, gasoline, diesel, and other liquid industrial gas

to refineries or storage facilities. These MLPs typically charge a fee based on the volume of gas that travels through their pipelines. The fee is often regulated by the Federal Energy Regulatory Commission (FERC). Once an interstate pipeline is built, the FERC has the authority to ensure that pipeline rates are “just and rea-sonable.” These rates are set to cover operating and maintenance expenses as well as an allowed return on investment (defined as a percentage of the capital in-vested in facilities used to serve customers). The FERC sets rates on a pipeline-by-pipeline basis and ap-proves the maximum allowable rate, or a rate cap, for each pipeline. But pipeline customers can and often do demand discounts from these maximum allowable rates. Thanks to fracking and the recent energy boom in the United States, domestic natural gas and crude oil production have increased significantly. As a result, many MLPs with large pipeline assets have reported record volume-based revenue and operating cash flows.

Product Storage

Some MLPs invest in gas storage facilities, the rev-enues of which are based on a competitive fee related to the volume of gas stored. Sometimes, however, an MLP that owns a storage facility will lease out a portion of the facility’s capacity for a preset fixed fee on a longer-term basis. While natural gas and crude oil pro-duction have risen quickly in the United States during the last decade, available storage capacity has not ex-panded quickly enough to keep pace with that demand. Thus storage capacity is an extraordinarily valuable as-set in this market situation.

Furthermore, in the natural gas and crude oil futures market, the normal shape of the futures contract price is referred to as contango, a situation where the futures contract price is higher than the current spot price. An MLP could take advantage of contango by simultane-ously buying natural gas or crude oil at the spot price and then selling the corresponding futures.4_{When the}

futures mature, the MLP can deliver the products stored at its facility for a higher price than the spot price paid.5

MLP Valuation and Risk Assessment

investors often use the P/E ratio (current price per share of stock divided by net income per share) or P/B ratio (price per share divided by book value per share). For MLPs, however, these ratios do not accurately reflect the true earning power or asset base of the underlying business of an MLP. Most MLPs have large amounts of noncash expenses (i.e., depreciation and amortization), the deduction of which—some would argue—may un-derestimate the amount of economic earnings reported by these entities. Overly inflated P/E ratios would de-press the attractiveness of an MLP from an investment standpoint.

In addition, the cumulative effect of historical-cost depreciation/depletion over time for MLPs with large pipeline assets likely results in reported book values on the balance sheet that greatly underestimate the current market value of these assets. Therefore, using a P/B ratio to help assess unit value for an MLP may not be appropriate either.

Given the above challenges, what can the investor or potential investor use to help inform the invest-ment decision regarding MLPs? Two metrics are recommended—one related to valuation and the other to risk assessment. One potential measure of valuation would be current selling price per unit divided by dis-tributable cash flow per unit. Disdis-tributable cash flow is defined as net income plus depreciation, amortization, and other noncash expenses minus maintenance expen-ditures.6_{For risk assessment, a coverage ratio relates to}

the risk position of an MLP. As noted earlier, many in-vestors are attracted by the high dividend payouts of MLPs, but the dividend yield does not tell the whole story. Because they typically retain less than 10% of earnings each year, MLPs constantly have to issue new units to finance their operations and expansion. In the-ory, an MLP not making any profit could still pay high dividends for an extended period by issuing new units. Therefore, to evaluate the sustainability (or risk) of an MLP’s high dividend rate, investors could calculate the so-called coverage ratio, defined as the ratio of distrib-utable cash flow for the year to the actual cash payout for the year. Some investors view a favorable coverage ratio as greater than 1.3 under the assumption that this level of coverage indicates the business has ample cash to continue paying distributions to unit-holders.

Investing in MLPs: Benefits and Risks

Investments in MLPs can be highly rewarding for a number of reasons:

◆ Most MLPs engage in fee-based crude oil, gasoline, and natural gas pipeline transportation businesses. As new exploration technology increases domestic oil and gas production volume in the United States, rev-enues generated by these MLPs will steadily in-crease, regardless of volatile oil and gas prices.

◆ Pipeline is the most cost-efficient method to trans-port crude oil and gas. It remains competitive over other methods, such as rail and trucking. As indi-cated in Figure 1, the vast majority of MLPs are in-volved in the midstream sector of the U.S. energy supply chain.

◆ Most MLPs commit to deliver a high annual cash distribution to their unit-holders, and they strive to increase cash distribution as often as possible. Many investors who need current income would find in-vesting in MLPs highly attractive.

◆ Investing in MLPs provides tax benefits, as previ-ously discussed.

On the other hand, investing in MLPs has significant risks:

◆ The U.S. Congress might eliminate or reduce favor-able tax treatments on the net income of MLPs and consequently reduce cash distributions to unit- holders.

◆ Crude oil, gasoline, coal, and natural gas—the main products for MLPs—might eventually be replaced by renewable energy sources, devaluing these fossil fuels to a significant degree.

◆ Most MLPs are highly leveraged. Therefore, rising interest rates will significantly affect future levels of net income and cash distributions from these entities.

◆ The organizational structure for some MLPs can be very complicated (as illustrated in Figure 3). Some investors may have trouble understanding an MLP’s business structure, which would inhibit their ability to critically evaluate the performance prospects and risks associated with a particular MLP. As noted, due diligence on the part of the investor is needed as part of the decision-making process.

Informed Investment Decisions

MLPs represent a unique asset class with highly attrac-tive features (and some risks) for investors. In their ex-panded role within the finance function, management accountants should have greater familiarity with the in-tricacies associated with MLPs. The descriptive infor-mation we included should help management accoun-tants make more informed decisions regarding investments in MLPs from both a professional and a personal perspective. ■

Contango), “contango means the price of a commodity (e.g.,

crude oil or natural gas) for delivery at a future date is signifi-cantly higher than the current or ‘spot’ price.” This makes it profitable for companies to store the commodity and “enter into contracts to sell futures contracts on the commodity, even after accounting for storage costs and opportunity cost of capital (i.e., money tied down on the inventory not earning a return).” (A fu-tures contract is a financial contract obligating the buyer to pur-chase an asset (or the seller to sell an asset), such as a physical commodity or a financial instrument, at a predetermined future date and price.) Also referred to as an upward sloping forward curve, contango persists until the futures prices come down, current prices go up, or the cost of storage becomes very high. 5 Although contango might seem to represent an arbitrage situa-tion on the surface, it is technically not the case because of the storage cost associated with the gas or oil. Once the company locks in the price in a futures contract, market changes do not matter. For example, assume that the spot oil price is $102 per barrel and an oil futures contract is currently trading at $110 per barrel. An MLP with a storage facility can buy and store at its facility, say, one million barrels of oil today for $102 per barrel. At the same time, it may sell 1,000 oil futures contracts (1,000 barrels per contract) at $110 per barrel. When the futures con-tract matures, the MLP will deliver the oil for $110 per barrel, for a profit of $8 million. This level of profit would be indepen-dent of what happened to the spot market and what happened to the specified futures market from the present to the point when the futures contracts matured.
