Cash Available for Distribution, usually shortened to CAD, is a non-GAAP measure of how much cash a business actually generates that it could hand to investors right now. It matters most for Master Limited Partnerships (MLPs) in the energy sector and Real Estate Investment Trusts (REITs), both of which are built to pass the bulk of their earnings straight through to investors. Reported net income at these entities is distorted by huge non-cash depreciation charges, so CAD strips those distortions out and gives you a cleaner read on whether the quarterly check is sustainable.
Where You’ll See CAD Reported
CAD is non-GAAP, which means no accounting body dictates exactly how to compute it. That flexibility is deliberate. MLPs and REITs both run asset-heavy businesses where depreciation dwarfs actual cash spending in any given quarter, and standard net income is a poor stand-in for distributable cash. Each sector fills the gap a little differently.
MLPs: CAD and Distributable Cash Flow
In the MLP world, the same idea usually goes by a different name: Distributable Cash Flow, or DCF. The two terms are interchangeable, and a widely used MLP glossary simply defines CAD as “see Distributable Cash Flow.” The general formula is EBITDA minus cash interest expense and maintenance capital expenditures. MLPs dominate pipelines, storage, and processing, where physical assets last for decades and annual depreciation is far larger than the cash actually needed to keep those assets running.
Because MLPs are pass-through entities that generally pay no corporate-level income tax, their whole point is to deliver cash to unitholders. That makes CAD (or DCF) the single most important number in an MLP’s financials, and analysts spend far more time on it than on reported net income.
REITs: CAD, AFFO, and FAD
REITs sit inside a slightly more layered framework. The National Association of Real Estate Investment Trusts (Nareit) created a standardized metric called Funds from Operations (FFO), which starts with GAAP net income, adds back depreciation and amortization on real estate, and removes gains or losses from property sales and certain impairment charges.1Nareit. Nareit Funds From Operations White Paper – 2018 Restatement FFO has a consensus definition, but it was never meant to measure dividend-paying capacity on its own.
Many REITs go a step further by subtracting recurring maintenance capital expenditures, adjusting for straight-line rent, and removing other non-cash items. The result is called Adjusted FFO (AFFO), Funds Available for Distribution (FAD), or Cash Available for Distribution (CAD), depending on the company. Nareit has expressly stated that no adequate consensus exists among preparers and users to settle on a single definition of FAD, CAD, or AFFO, so each REIT defines its own version in its filings.1Nareit. Nareit Funds From Operations White Paper – 2018 Restatement Investors need to keep that in mind when comparing REITs side by side.
REITs also carry a structural requirement MLPs do not: to keep their tax-advantaged status, a REIT must distribute at least 90 percent of its taxable income to shareholders each year.2Office of the Law Revision Counsel. 26 USC 857 – Taxation of Real Estate Investment Trusts CAD helps you judge whether that mandated payout is comfortably covered by real cash flow or whether the REIT is straining to hit the threshold.
How CAD Is Calculated
The calculation starts from a GAAP number, typically net income, EBITDA, or cash flow from operations. From there, adjustments strip out non-cash accounting entries and set aside cash for asset upkeep. The point is to isolate the recurring cash the business can reliably produce, quarter after quarter.
Adding Back Non-Cash Charges
Depreciation and amortization are the biggest add-backs. A pipeline MLP might book hundreds of millions in annual depreciation on infrastructure that still works perfectly and needs only modest upkeep. That depreciation cuts reported net income without consuming any cash, so it gets added back into the pool of distributable funds.
Other common add-backs include deferred income taxes (which arise when tax and financial depreciation schedules diverge), unit-based compensation, and amortized financing costs. Each of these reduced reported earnings without money actually leaving the business.
Subtracting Maintenance CapEx
The most scrutinized line in the CAD formula is maintenance capital expenditures. This is the cash the business must spend to keep existing assets running at current capacity. Replacing a corroded pipe section or resurfacing a parking deck qualifies. That money is genuinely gone and cannot be distributed.
Subtracting maintenance CapEx is what separates CAD from cruder cash flow measures. Without it, a partnership or REIT could report inflated distributable cash by quietly neglecting its asset base, essentially liquidating itself in slow motion.
Working Capital and One-Time Items
Changes in working capital also need adjustment. A seasonal inventory buildup ties up cash temporarily, so it gets subtracted. A jump in accounts payable means the business held onto cash longer, so it gets added back. These moves smooth out quarter-to-quarter noise.
One-time items get stripped for the same reason. A gain on the sale of a processing facility, a legal settlement, a restructuring charge, a write-down — each is removed so CAD reflects only ongoing operations. The whole exercise answers one question: how much cash does this business reliably generate from its normal operations?
Why Maintenance CapEx Deserves the Closest Look
The line between maintenance CapEx and growth CapEx matters enormously, because only maintenance spending is subtracted from CAD. Growth CapEx, which funds new assets or expanded capacity, sits outside the calculation. Building a new pipeline spur is growth. Replacing a valve on an existing pipeline is maintenance.
The problem is that no standard definition of maintenance CapEx exists across firms. Management teams have real discretion in classifying borderline spending, and the incentive tilts toward calling things growth. Every dollar reclassified from maintenance to growth inflates reported CAD and makes the distribution look safer. Analysts know this, and it’s the single most common place skepticism is warranted.
A useful check is to compare a company’s reported maintenance CapEx against peers running similar assets. If one pipeline operator consistently reports maintenance spending at half the rate of competitors with comparable infrastructure, it may be deferring necessary upkeep. That deferred spending does not vanish. It builds up as a hidden liability that eventually forces a large catch-up outlay, often paired with a distribution cut. Partnerships typically disclose their classification methodology in the footnotes, but “disclosed” and “transparent” are not the same thing.
The Distribution Coverage Ratio
CAD feeds directly into the distribution coverage ratio, the single most important number for evaluating payout sustainability. The calculation is simple: divide total CAD for a period by total cash distributions paid during that period.
A coverage ratio above 1.0x means the entity generated more cash than it paid out. A ratio of 1.20x means the business produced $1.20 in distributable cash for every $1.00 distributed. That 20-cent cushion absorbs operating volatility and can fund modest debt repayment or small projects without tapping external capital. Industry data suggests 1.2x or better is generally considered a healthy benchmark.
A coverage ratio persistently below 1.0x is a red flag. At 0.90x, the business pays out a dollar for every ninety cents it generates, and the shortfall has to come from somewhere: new debt, new unit issuances, or asset sales. None of those are sustainable long-term sources of distribution funding, and all of them dilute or leverage existing investors. A sub-1.0x ratio that runs for more than a quarter or two frequently precedes a distribution cut.
Analysts also use CAD to calculate a CAD yield: annualized CAD per unit divided by the current market price. Comparing CAD yields across MLPs or REITs gives a standardized measure of cash-generating efficiency that sidesteps the accounting-policy differences buried in GAAP net income.
A Note on Per-Unit CAD in MLPs with IDRs
Some MLPs still operate with incentive distribution rights (IDRs), a structure under which the general partner takes an increasing share of incremental cash flow as distributions to limited partners hit set thresholds. The GP’s cut typically starts around 2 percent and can climb to 50 percent at the highest tiers. Where IDRs are in place, aggregate CAD overstates what actually reaches limited partners, so look at CAD on a per-LP-unit basis instead of the headline total. Many large MLPs have simplified or eliminated their IDR structures in recent years.3Investopedia. Incentive Distribution Rights (IDR)
Warning Signs That a CAD Figure May Be Misleading
Because CAD is non-GAAP with no universal definition, the room for manipulation or honest miscalculation is real. Experienced investors watch for a few patterns.
- Persistently negative free cash flow. If a partnership distributes nearly all its operating cash flow and then borrows heavily to fund growth, the whole model depends on continued access to cheap capital. When credit tightens, the model breaks.
- Declining maintenance CapEx ratios. A steady drop in maintenance spending as a share of assets or revenue can signal deferred upkeep rather than genuine efficiency gains.
- Heavy reliance on capital markets. Unlike traditional corporations that retain earnings to fund growth, most MLPs distribute the bulk of their cash and must raise external capital to expand. That dependence leaves them exposed to interest rate spikes and equity market downturns.
- Inconsistent adjustments between periods. If the list of “non-recurring” items changes every quarter, management may be cherry-picking which charges to exclude. Genuine one-time events do not happen every quarter.
The lack of a standardized definition means you have to read the footnotes carefully and understand exactly what each company includes and excludes. Two partnerships in the same subsector can report very different CAD figures using equally defensible methodologies.
Reading the GAAP Reconciliation
Because CAD is a non-GAAP measure, any company that reports it publicly must comply with SEC Regulation G. The core requirement is that any public disclosure of a non-GAAP financial measure must be accompanied by the most directly comparable GAAP measure and a quantitative reconciliation showing how the company got from the GAAP figure to the non-GAAP one.4eCFR. 17 CFR Part 244 – Regulation G For CAD, that typically means reconciling back to GAAP net income or GAAP cash flow from operations.
The SEC also limits how non-GAAP measures can be presented. A non-GAAP liquidity measure like CAD cannot be presented on a per-share or per-unit basis in documents filed with the Commission. Excluding normal, recurring cash operating expenses from a non-GAAP performance measure may also be deemed misleading, even when management frames those expenses as non-core.5SEC.gov. Non-GAAP Financial Measures
Practically, the GAAP-to-CAD reconciliation table in a company’s earnings release or 10-K is required reading. It shows exactly which items management added back or subtracted and lets you judge whether those adjustments are reasonable. If a company reports CAD but buries the reconciliation or omits it entirely, that is both a regulatory violation and a reason to be skeptical of the number.
Limitations to Keep in Mind
CAD is the best available measure of distributable cash, but it has real weaknesses.
The biggest is the lack of a standardized definition. Two MLPs with identical assets and identical cash flows can report different CAD figures based on nothing more than how they classify maintenance versus growth spending. Nareit has acknowledged that no consensus exists on a single definition of CAD, FAD, or AFFO across REITs.1Nareit. Nareit Funds From Operations White Paper – 2018 Restatement Cross-company comparisons require reading each company’s methodology, not just glancing at the headline number.
CAD also relies heavily on management estimates, particularly for maintenance CapEx. Unlike depreciation, which follows set GAAP schedules, maintenance spending is a judgment call. Management has both the discretion and the incentive to understate it, since lower maintenance CapEx directly inflates CAD and makes the coverage ratio look healthier.
Finally, CAD is backward-looking. It tells you what the business generated last quarter, not what it will generate next quarter. A pipeline MLP with strong current CAD but declining contract volumes, or a REIT with healthy cash flow but rising vacancy rates, may be reporting peak distributable cash right before a sharp decline. Pairing CAD with forward-looking indicators like contract expirations, lease renewal rates, and commodity price exposure gives you a fuller picture than any single metric can on its own.
