When it comes to valuing midstream MLPs, many valuation lessons have already been learned. Investors who are experts in other asset classes try to use Price/Earnings (P/E) ratios, but they include accelerated depreciation (a pure accounting value practically irrelevant to the ongoing fundamental business), making such numbers nearly nonsensical for asset intensive businesses (including Utilities). Using Price/Distributable Cash Flow (P/DCF) is the MLP equivalent, although that fact is not well known outside this space. Since under normal market conditions, MLP yields are steady and predictable, using yield has a valuation metric has become unreasonably popular.

**Why Using Yield Doesn’t Work**

For years, it has been known that the most accurate way to value midstream MLPs is to use a P/DCF ratio, or Enterprise Value/EBITDA (EV/EBITDA). Still, if one made a number of assumptions that generally held true, it was possible to calculate valuations on the proverbial bar napkin.

The assumptions are as follows:

(1) an MLP pays out nearly all of its DCF each quarter in the form of distributions,

(2) incoming cash flows are stable and increase only when growth has taken place,

(3) external financing is readily available to fund projects, and

(4) unit prices reflect distribution changes and expectations.

If these are true, then the yield on a given MLP can be an accurate reflection of its value. Looking over the past 5-6 years, if these four assumptions held (and Treasuries stayed relatively stable), then the following heuristics were also generally accurate: A company with multi-year expected distribution growth in the double digits typically will have a yield less than five percent. Companies with flat distribution growth typically trade around eight percent under normal market conditions. Those companies expected to cut distributions will trade to double digit yields in the teens or higher.

An investor looking to use yield as a valuation metric might use a chart similar to the below. A ten-year median yield target is of course an arbitrary measure of fair value. Still, it is worth noting that despite what was said above about double-digit yields indicating investor belief in a forthcoming distribution cut, Enterprise Products Partners (EPD) has in fact raised its distribution each quarter for the past 55 quarters. Likewise, despite a yield below 4% in 2013, EPD’s distribution growth has been around 5%-8% over the past ten years, never in the double-digits. Yield is a valuation short-cut, but like all short-cuts, it has short-comings.

The short-comings of a yield as a valuation metric are even more prominent now that distribution cuts for midstream MLPs are within the realm of imagination (and, according to some analysts, not only possible, but probable and desirable). Cash that was previously paid out in the form of distributions is now being viewed as a potential financing source. Thus, any valuation metric that relies on the yield (which relies on the distribution) is useless.

**How to Use P/DCF**

To value a midstream MLP, investors will have to do some homework. Instead of simply measuring the cash distributed, investors will have to research how much cash is generated. For MLPs, the best metric to measure useable cash is Distributable Cash Flow (DCF) . Unfortunately, Alerian has yet to find a data provider who reliably calculates DCF (understandable, since DCF is quite company-specific and difficult to automate unless a computer understands how to read footnotes in SEC filings).

A basic DCF calculation begins with net income, adds back depreciation and amortization, removes maintenance capex, and adjusts for any noncash items (such as deferred income tax) and nonrecurring items (such as proceeds from asset sales).

Once DCF has been calculated, a P/DCF ratio can be calculated and compared to the company’s own historical levels as well as to peers. By including the investor’s views as to the future of the MLP, DCF can be estimated on a forward basis. And then, viola, the investor can ascertain whether the MLP is trading above or below an appropriate P/DCF ratio.

**Enterprise Products Partners as an Example**

This is all easier said than done, of course. As an example, I calculated historical numbers for EPD. Earnings press releases provide all the numbers necessary to calculate ten years of historical DCF, and even include EPD’s own adjusted DCF number . Since EPD now provides distribution growth guidance, I was able to back into a projected DCF number for 2016 using an estimated coverage ratio of 1.3x .

P/DCF was calculated using the market cap on the last day of the year and the next year’s actual DCF value.

Given this projected 2016 DCF of around $4.2billion, what is an appropriate value for EPD? As I work for an indexing firm, it would be inappropriate for me to suggest a “correct” answer to that question, because it depends on the multiple you use.

Over the years, Enterprise’s P/DCF multiples have ranged from 5x-17x. In determining which P/DCF multiple to use, it comes down to risk-adjusting expected returns. Consider business model risk: businesses with more commodity exposure suggest a lower multiple. So, a small cap G&P MLP with single basin exposure should have a lower P/DCF than a large, interstate natural gas pipeline company. In other words, an investor is willing to pay a premium (higher) multiple for less commodity-sensitive or diversified cash flows. Beyond that, consider a company’s leverage: how much debt has it taken on and can it afford those payments? Does it have a supportive general partner, affordable access to capital, and backlog of visible growth via drop-down assets?

**Who Should Use P/DCF**

Calculating DCF and determining an appropriate multiple are a lot of work. Technical traders have their own bewildering array of algorithms, but it is those patient investors looking for value within the sector who will find the most utility in P/DCF calculations. All the same, I hope this example has given you not only an idea of a reasonable trading range for EPD, but also how to calculate these numbers for other energy infrastructure companies. It is a lot of work, I’ll grant you. But if something is worth doing, it’s worth doing right.
