This MLP Fund’s Yield Reels In Assets

AMZA has the third-highest yield of all ETFs. The reason requires a peek under the hood.

Investors have flocked to the $539 million InfraCap MLP ETF (AMZA), pouring more than $475 million into the fund over the past 12 months. The question is, why?

Though AMZA gained some notoriety awhile back, when it rose 68% over the course of 2016, the fund's more recent performance has been underwhelming, to say the least. Over the past 12 months, the fund has lost 20.29%, three points below the average for MLP ETFs:



AMZA also carries a whopping 1.93% expense ratio, placing it among the most expensive ETFs, MLP or not.

So why do investors keep returning to this underperforming, uber-expensive fund?

It's simple, really: yield—and lots of it. Currently, AMZA offers an eye-popping 33.99% dividend yield, the third-highest of all ETFs.

How AMZA achieves that yield, however, isn't so simple.

Oasis For Yield-Starved Investors

AMZA is one of 29 exchange-traded products tracking master limited partnerships (MLPs), a lesser-known corporate structure seen primarily in the energy industry. MLPs are pipeline operators, storage facilities, oil and gas refiners—any "toll road"-style business whose revenues benefit more from volume than commodity price.

MLPs are odd ducks, from a tax perspective. As partnerships, they're not taxed at the entity level. Instead, they "pass through" any taxable gains and income to their shareholders—meaning, the end investor.

Because of the stable nature of their income stream, MLPs also tend to be excellent sources of yield. The historical average yield for MLP investments hovers around 7.5%.

That makes AMZA, with its 33.99% yield, a veritable oasis for yield-starved investors, as does its recent change to monthly—rather than quarterly—payments.

AMZA's Structure Matters

Yet as it turns out, it's not immediately obvious that AMZA, or any MLP ETF, should offer such sky-high yields, because ETFs are restricted severely in how much of their portfolio can actually be dedicated to MLPs.

Because the tax rules around limited partnerships are so unusual, the IRS limits their inclusion in '40 Act funds (like most ETFs) to no more than 25% of total assets.

That makes it hard to create a pure-play MLP ETF in a traditional '40 Act wrapper. Funds that make the attempt, such as the First Trust North American Energy Infrastructure Fund (EMLP) or the Global X MLP & Energy Infrastructure ETF (MLPX), often have to supplement their direct MLP exposure with institutional shares, Canadian energy companies, even utilities. Doing so also means a dramatic hit to yield.

The C-Corporation Get-Around

One way to circumvent the 25% cap is to structure the ETF as a C-corporation. A fund structured as a C-corp works just like an Apple or an Exxon, and it can hold any asset that these companies can, including MLPs. AMZA is one of six MLP ETPs structured as a C-corp.

There's a catch, however. Funds that are C-corps must pay corporate income taxes, even if their underlying assets are pass-through. (The federal corporate rate used to be a maximum 35%, but the recent Tax Cuts and Jobs Act reduced it to 21%.)

Furthermore, any income distributions the fund makes are treated like dividends, and taxed accordingly, just like any distribution made by Apple or Exxon.


Return Of Capital Means Tax Free

That's not the end of the story. MLPs make two kinds of distributions: income and return of capital. Any distribution classified as "return of capital" isn't taxed; instead, it lowers an investor's cost basis in the MLP (more on that in a minute).

C-corps that hold MLPs can take advantage of this distinction in distributions as well. According to the 19a-1 forms posted on AMZA's website, the majority of dividends paid by the fund have in fact been treated as return of capital.

A 33.99% dividend yield, with tax-free payments? No wonder investors have piled into AMZA en masse.

Not A Pure-Play MLP Fund

That said, AMZA achieves its sky-high yield using an unconventional portfolio, one bound to leave investors who expected yet another pure-play MLP fund potentially scratching their heads.  

In addition to 31 MLPs and a handful of other energy companies, AMZA also holds 216 options contracts, including calls and puts on the SPDR S&P 500 ETF Trust (SPY), the United States Oil Fund LP (USO) and the United States Natural Gas Fund LP (UNG), the iShares 20+ Year Treasury Bond ETF (TLT), and even on competing MLP ETFs, like the J.P. Morgan Alerian MLP Index ETN (AMJ).

It also holds 18.7% of its portfolio in short positions, including USO, UNG and AMJ, as well as in options contracts on a variety of ETPs.

The reason for this is that AMZA is an actively managed MLP ETF, one of only two on the market (the other is EMLP). As such, AMZA has the leeway to employ leverage, shorting and active options strategies to help boost its current income.

Active Strategies Pay Off

In particular, AMZA has deployed to great success a common options strategy known as "covered calls." In a covered call, an investor holds a long position in a given asset, then "writes" (or sells) a call option on that asset giving the holder the right, but not the obligation, to buy it at some preset price in the future.

Covered calls act as insurance policies that can provide solid income in choppy or anemic markets. (read: "Exploring Covered Call Strategies"). According to the fund's most recent annual report, that's exactly what AMZA's fund managers have tried to do, using covered calls as a means to boost income for distribution to investors, as well as for hedging purposes.

Furthermore, AMZA takes the unorthodox stance of shorting energy prices, as represented by USO and UNG. While not a bad idea in theory, given the underperformance in the energy market of late, it seems counterintuitive on first glance for an ETF that holds energy companies to short oil and gas prices.

Yet it makes sense, given that MLPs—like pipelines and refiners—make money not on the rise and fall of commodity prices, but on how much volume of a given commodity passes through their infrastructure. (It also speaks to an existential question that underlies MLPs in general: Are MLPs an energy play, or an income one? Clearly, AMZA leans toward the latter.)

There's Always A Catch

The upside of active management is that AMZA offers truly astronomical yield. The next closest yield is offered by the twice-leveraged Credit Suisse X-Links Monthly Pay 2x Leveraged Alerian MLP Index ETN (AMJL), at 23.14%. But as an ETN, its distributions will be taxed at ordinary income rates.

The next highest yield offered by a C-corp MLP ETF, with the preferential tax treatment, is from the Direxion Zacks MLP High Income Index Shares (ZMLP), which has a dividend yield of just 11.55%.

The downsides to AMZA's approach are twofold, however. The first was alluded to earlier: All this active management comes with an exorbitant 1.93% expense ratio. That's by far the highest in the MLP space, and is the 27th-highest among all ETFs, period.

Secondly, tax-free return of capital distributions, like those offered by AMZA, also lower your cost basis, meaning investors will find themselves with a higher tax liability when it comes time to sell.

In fact, since a cost basis can never go below zero, if you hold AMZA long enough, conceivably there could come a time when its distributions wipe out your cost basis.

If so, that would mean all future distributions would be taxed at the highest possible rate: as ordinary income.
