Investor WorkspaceA little clarity for your next decision.
By Jerry Baker
FFO, AFFO, and NAV help you review different parts of a REIT: its reported performance, selected earnings adjustments, and estimated net asset value. None tells you, by itself, how much cash you will receive or what your shares will be worth when you sell. Start with the financial statements, then trace each measure back to its definition and the claims ahead of you.
A REIT report can feel like someone spilled alphabet soup on an income statement. I find it easier to start with the question each number is meant to help answer.
The first two describe a period, such as a quarter or a year. NAV is an estimate at a point in time. Comparing annual FFO with a current share price can be useful. Comparing a year’s cash distributions with a stale NAV without noting the dates can be misleading.
These measures supplement the financial statements. They do not replace them. SEC guidance treats qualifying FFO as a non-GAAP performance measure and sets conditions for other adjustments. A familiar label does not excuse a misleading calculation. [1]
Generally accepted accounting principles, or GAAP, provide the starting framework for a public REIT’s statements. The income statement reports revenue, expenses, and earnings. The balance sheet reports assets, liabilities, and equity. The cash flow statement explains cash from operations, investing, and financing. Read them together. [2]
Rental revenue does not always equal rent collected during that period. A lease may have free rent or scheduled increases. Accounting rules can spread recognized rent across the lease term. The receivable and cash flow disclosures help explain the timing.
Depreciation also affects earnings without requiring a cash payment in that period. But the building’s roof, elevators, and systems can still wear out. Adding depreciation back does not make those needs disappear.
Nor does it prove the property rose in value. A well-kept building can lose value because rents weaken or buyers demand a higher return. GAAP earnings, property value, and cash available to owners answer different questions. I want to see the differences explained, not choose whichever number looks best.
When a report says an expense is noncash, ask whether there is another economic cost. Stock paid to employees, for example, can affect ownership per share even though it does not require the same immediate cash outlay as wages.
Nareit’s FFO definition begins with GAAP net income. It adjusts for real estate depreciation and amortization, specified property sale gains and losses, and certain real estate impairment charges, with related ownership adjustments. The full definition matters, especially for joint ventures. FFO is not simply rent minus expenses. [3]
Consider a simplified, hypothetical property-owning REIT. All amounts below belong to common stockholders for the same full year. Assume there are no preferred claims, joint ventures, or other FFO adjustments:
| Item | Amount |
|---|---|
| GAAP net income | $20 million |
| Add real estate depreciation and amortization | $30 million |
| Remove qualifying property sale gain | ($8 million) |
| Illustrative FFO | $42 million |
The arithmetic is $20 million plus $30 million minus $8 million. FFO is higher than net income, but neither number is automatically wrong. Each includes different items for a different purpose.
The sale gain was removed because this measure separates specified property sale results from the ongoing performance it seeks to describe. That does not mean the sale was unimportant. The cash raised, debt paid, and income lost after the sale still matter.
Likewise, an impairment add-back does not erase the event that caused a property write-down. I would still want to understand the tenant loss, damage, change in plans, or market decline behind it. The bridge explains the adjustment; the property review explains the risk.
AFFO has no single standardized definition. Issuers may adjust FFO for rent timing, leasing costs, recurring property work, and other items. That can provide useful context, but two companies can use the same label for different calculations. [4]
Continue our hypothetical example. Suppose the issuer removes $3 million of straight-line rent income and subtracts $5 million of recurring property and leasing costs. It adds back $2 million of noncash stock compensation. Its stated AFFO would be $36 million: $42 million minus $3 million minus $5 million plus $2 million.
This is an invented definition for teaching, not a formula every REIT follows. Before accepting it, I would ask:
SEC staff guidance warns that some non-GAAP adjustments can mislead, including certain exclusions of normal recurring cash operating expenses. Inconsistent treatment across periods also needs scrutiny. These are reasons to inspect the reconciliation, not treat the word “adjusted” as a seal of quality. [1]
Keep both figures on your worksheet. If management changes its definition, ask for comparable prior periods and the reason. Growth created by a new definition is different from growth in rents or lower borrowing costs.
Prologis’s July 16, 2026 results provide a useful example. Its reconciliation moves through modified FFO and Core FFO before AFFO. Core FFO removes certain development and land sale gains; AFFO brings those gains back, net of related tax, while making other adjustments. Its AFFO table also deducts property improvements and turnover costs. [5]
That is this issuer’s method for this report. It does not establish a definition for every REIT. The company also states that its FFO measures do not replace GAAP earnings or operating cash flow and do not measure its ability to fund all cash needs. [5]
The practical lesson is to read down the table. Do not assume AFFO always excludes sale gains, always deducts every capital need, or means cash available for your distribution. A label is the beginning of the review.
Now return to our hypothetical REIT. Its cash flow statement reports $34 million from operations. It spends $7 million on property and leasing work and must repay $4 million of loan principal. That leaves $23 million before acquisitions and other uses.
Assume it pays $30 million in common distributions. The gap is $7 million. Its $36 million AFFO does not make that gap vanish.
The gap could be met with existing cash, borrowing, property sales, or new capital. The source, amount, and effect on future earnings need review. A disclosed gap is not automatically evidence of fraud, and one year may include unusual spending. It is still a question that needs an answer.
SEC disclosure guidance for non-traded REITs specifically addresses the relationship between distributions and operating cash flow, as well as the sources used to fund payments. Those disclosures are useful starting points for understanding the cash path. [6]
Do not subtract an expense twice. Some property costs pass through operating cash flow, while other spending appears in investing activities. Map the line items before building your own cash estimate. Label any calculation you make so it is not mistaken for an issuer measure.
Company growth does not always mean growth for each share. Suppose FFO rises from $100 million to $110 million. That is 10% growth. But weighted-average shares rise from 50 million to 60 million. Simplified FFO per share falls from $2 to about $1.83, a decline of roughly 8.3%.
New shares may fund useful assets, and the timing of those assets’ earnings can matter. The point is not that new issuance is always bad. It is that a larger company and a better result per share are different claims.
Use the issuer’s proper ownership and diluted-share calculations. A consolidated property may be partly owned by others. An unconsolidated venture may contribute only the REIT’s share of results. Common shares, preferred shares, and operating partnership units can have different claims. A numerator for one group should not be divided by a denominator for another.
Dates matter just as much. Compare a full year’s distributions with that same year’s earnings measure. A quarterly number multiplied by four is an annualized illustration. It is not a full year of actual results.
Seasonal revenue, property sales, one-time costs, and rent collections can make one quarter unusual. Read several periods and explain changes. The latest quarter helps update the picture; it should not erase the rest of it.
Using the same-year figures in our example, $30 million of common distributions divided by $42 million of FFO produces a 71.4% payout ratio. Dividing by $36 million of AFFO gives 83.3%.
Both calculations can be arithmetically correct. Yet the separate cash check still showed only $23 million after the stated spending and required principal payments.
A ratio below 100% is not a guarantee that a distribution is secure. The definition may omit important demands on cash. A ratio above 100% is not a complete diagnosis either. It may reflect an unusual period, a special payout, or a funding practice that needs closer review.
Ask whether the cash flow can support the payment through a weaker period. Which leases expire? Which loans reset? What property work is due? Are reserves available for distributions, or restricted for another use?
Taxable income is another separate measure. The REIT distribution test is based on a defined taxable-income calculation, with special adjustments. It is not a rule requiring payment of 90% of FFO, AFFO, rents, or the cash you invested. [7]
NAV attempts to estimate what remains after subtracting debt and other claims from asset value. For a common-stock estimate, preferred claims and ownership interests held by others also need proper treatment. The share count and class terms must match the value being measured.
Here is a simplified hypothetical estimate:
With 25 million matching common shares, the estimate is $9 per share. The calculation assumes no other ownership claims, transaction costs, or adjustments. A real valuation may need all of those.
Do not substitute the property’s book value for estimated market value and call the result a market-based NAV without explaining the method. Also ask whether debt is measured at its balance or estimated fair value, how joint ventures are included, and which fees or taxes are reflected.
For non-traded REIT estimates, SEC staff guidance calls for explanations of valuation methods, assumptions, limitations, and differences from amounts a sale might produce. Those details matter more than a precise-looking number. [6]
A direct-capitalization estimate divides a property’s annual net operating income by an appropriate capitalization rate. This is one valuation method, not a complete appraisal for every property or stage of development. [8]
Assume a hypothetical property earns $6 million of stable annual NOI. At a 5% cap rate, the estimate is $120 million. At 6%, it is $100 million. The same income supports a value about 16.7% lower when the assumed rate rises.
With $60 million of debt and no other changes, estimated equity falls from $60 million to $40 million. That is a 33.3% decline. Debt makes the effect on equity larger than the percentage change in property value.
Now ask what happens if both income and the valuation rate change. At $5.4 million of NOI and a 6% cap rate, property value is $90 million. After the same debt, equity is $30 million—half the original $60 million.
These are sensitivity tests, not forecasts. A realistic valuation also considers leases, needed capital work, market evidence, and other property facts. Showing the range helps you see which assumption matters. It does not tell you which outcome will occur.
Exchange-listed shares trade at prices set by buyers and sellers. Those prices may differ from an analyst’s NAV estimate. A discount can reflect concern about debt, future rents, fees, management, or the estimate itself. It is not automatic proof of a bargain.
For non-traded shares, the company may use an estimated value in subscription or repurchase pricing. That does not promise you can sell all your shares at that value when you want. Read the actual program’s eligibility, limits, deductions, and suspension rights. [9]
Suppose shares cost $8 and an estimate says NAV is $10. The stated discount is 20%. If an updated estimate is $7, the same $8 price is about 14.3% above that estimate. The calculation is easy; judging the estimate is the hard part.
For a planned cash need, I care about the expected route to spendable money. A statement value, an accepted sale order, a completed repurchase, and cash in a bank account are different stages.
Suppose hypothetical REIT A trades at $30 and reports $2 of annual FFO per common share. Its price-to-FFO ratio is 15 times. REIT B trades at $24 and reports $1.50 of comparable annual FFO per share. Its ratio is 16 times. The lower share price does not produce the lower multiple.
Now assume A reports $1.60 of AFFO per share and B reports $1.20. Their price-to-AFFO ratios would be 18.75 times and 20 times. Those calculations do not prove A is the better choice. You still need to compare the adjustments, the assets, the debt, and the outlook.
Do not divide one REIT’s current price by next year’s forecast and another’s by last year’s actual result without labeling the difference. Forecast earnings have not happened. A change in the forecast can change the apparent multiple even if the share price stays still.
Keep debt in view, too. A common-share price divided by common-share FFO is an equity comparison. It is not a property cap rate. FFO generally reflects financing and company-level items that property NOI does not. Using the two ratios as if they were interchangeable can hide leverage.
There is also no requirement that NAV and FFO move together. Higher rent collections can improve current performance while a higher valuation cap rate lowers estimated asset value. A property sale can provide cash and reduce future rent. A refinancing can leave the property unchanged but raise the interest cost borne by common owners.
Those differences are not reasons to give up on the numbers. They are reasons to describe the event. A useful comparison explains what the investor is paying for and which assumptions could change that view.
I would put four lines at the top of a review: GAAP earnings, FFO, issuer-defined AFFO, and operating cash flow. Under them, I would list major capital needs and debt payments. On a separate page, I would show NAV assumptions and exit terms.
Then I would write what changed. Did higher earnings come from better rent collection, more properties, a sale gain, a revised adjustment, or more leverage? Did per-share results improve? Did the estimate change even though the properties did not sell?
The final question is what the evidence leaves unresolved. Perhaps tenant work is rising, a loan comes due soon, or the valuation uses old rent assumptions. State the missing fact and the document needed to resolve it. Record the reporting date beside each figure so a later update can be compared fairly. A neat spreadsheet should make uncertainty visible, not hide it.
I do not need every measure to say the same thing. I need to understand why they differ and whether the investment still fits the person considering it.
No. FFO adjusts GAAP earnings for specified items. Operating cash flow measures cash generated or used by operations under the accounting rules. Timing differences and other adjustments can make them diverge. Review both, then account for spending and obligations outside operating cash flow. [2] [3]
It can add useful information, but accuracy depends on the question and the definition. AFFO is not standardized. Read every adjustment and the reconciliation rather than assume it measures all cash available for distributions. [4]
No. An accounting adjustment is not a market appraisal. A property can need major repairs or lose market value even when depreciation is added back in FFO. Review the building, its leases, its capital needs, and the valuation separately.
There is no single passing ratio for every REIT. Match the period and ownership claims, inspect the definition, and review actual cash needs. A lower ratio can provide room under that measure, but it does not guarantee future payments.
No. The federal distribution test uses a defined taxable-income base and special adjustments. FFO and AFFO are different measures. The test does not promise a fixed distribution or protect the investor’s principal. [7]
Not necessarily. Estimated value and the right to exit are separate. Repurchase programs can have limits, conditions, and suspension rights. Check the current documents and your share class rather than treat NAV as cash waiting to be withdrawn. [9]
Only with care. Compare business models, definitions, debt, ownership claims, periods, and share counts. A lower price-to-FFO ratio may reflect higher risk or weaker prospects. It is a starting point for a question, not a complete investment decision.
Educational information, not an offer or a personal tax, legal, or investment recommendation. Examples are hypothetical and omit stated adjustments. Tax treatment depends on your facts and current law. Review your transaction with your CPA, attorney, and qualified intermediary. Real estate investments can lose value and may be illiquid.
