What FFO measures
Funds from operations is a supplemental performance measure for equity REITs. Nareit's definition starts with GAAP net income and makes specified adjustments for real estate depreciation, certain property disposal results, gains and losses from changes in control, and qualifying impairments. The purpose is to make recurring real estate performance easier to interpret when historical-cost depreciation dominates accounting earnings. FFO is neither the cash-flow statement nor the amount legally required to be distributed. A mortgage REIT needs a different analytical framework because its main assets are loans or securities rather than depreciable buildings.
Hypothetical arithmetic: earnings to FFO
- Net income
- 40
- Depreciation adjustment
- + 50
- Property-sale gain
- − 10
- Simplified FFO
- = 80
Assume annual net income attributable to common shareholders is $40 million, qualifying real estate depreciation is $50 million, and a qualifying property sale gain is $10 million. Simplified FFO is 40 + 50 − 10 = $80 million. With 20 million diluted weighted-average shares, FFO is $4.00 per share. If the company spends $15 million maintaining buildings, that expenditure still matters even though this simplified FFO bridge does not deduct it. These invented figures omit other possible adjustments.
Use the bridge, then the share count
Read each reconciliation line before accepting the headline. Distinguish Nareit FFO from management's additional measures labeled core, normalized, or adjusted FFO. Then ask whether the result belongs to common shareholders after preferred claims and noncontrolling interests. Aggregate growth can coexist with declining FFO per share when acquisitions require many new shares. Match annual performance with annual weighted-average diluted shares; a quarter-end share count can give a misleading result after a large issuance. For historical comparisons, keep ownership scope and reporting periods consistent.
Two useful, competing perspectives
An operating perspective treats FFO as a cleaner starting point than earnings per share for comparing property businesses. A capital-preservation perspective asks what the add-back hides: roofs age, elevators need replacement, and tenants demand improvements. Both views can be useful. A growing FFO figure supported by healthy occupancy has different implications from growth accompanied by mounting deferred maintenance. Compare capital spending and leasing obligations separately instead of assuming that the accounting depreciation add-back makes all reported earnings economically distributable.
A source-reading workflow
Open the issuer's annual filing and locate net income, its FFO reconciliation, diluted shares, the cash-flow statement, and capital commitments. Recreate the bridge for two periods and annotate changes in definitions. Use Nareit's guidance to understand the standard; use the issuer's notes to understand its application. Finally, explain any difference between FFO growth and operating cash-flow growth. Working capital, payment timing, and cash rent can create legitimate differences. Unexplained differences are a reason to read further, not proof of misconduct.
A common mistake
Calling FFO cash available for dividends overlooks capital spending, financing needs, and working-capital movements.
What to check in the disclosures
- Separate Nareit FFO from issuer adjustments.
- Check the common-share ownership basis.
- Compare total and per-share growth.
- Read capital spending alongside FFO.
