Why AFFO exists
Adjusted funds from operations attempts to move from FFO toward a recurring economic earnings measure. Common adjustments address straight-line rent and recurring capital expenditure, but there is no universal AFFO definition. A label shared by two issuers does not guarantee comparable calculations. AFFO should therefore be read as a management-defined analytical estimate with a reconciliation, rather than a standardized cash balance. It can help frame dividend capacity, but cannot independently establish that a distribution is sustainable.
Hypothetical arithmetic: two reasonable views
- FFO
- 100
- Straight-line rent + recurring expenditure
- − 8 − 12
- First AFFO view
- 80
- With compensation add-back
- 84
Suppose FFO is $100 million. Deduct $8 million of straight-line rent and $12 million of recurring property expenditure to obtain simplified AFFO of $80 million. If the issuer also adds back $4 million of stock compensation, its reported version becomes $84 million. A $60 million common dividend is 75% of the first figure and approximately 71.4% of the second. Neither ratio changes the cash dividend; the different denominators explain the difference. This invented example is a sensitivity exercise, not an issuer definition.
Inspect the difficult adjustments
Sort adjustments into cash timing, recurring property investment, financing accounting, and claimed exceptional items. Straight-line rent can recognize revenue before the lease cash arrives. Tenant improvements and leasing commissions may be necessary to preserve occupancy even when paid irregularly. Stock compensation is noncash today but can dilute shareholders. An acquisition expense may be unusual for one business and routine for a serial acquirer. Write down which costs you would retain in a conservative view and show that alternative alongside the issuer's calculation.
Management's view and the owner's view
Management may normalize volatile expenditures to make quarterly trends easier to understand. An owner may prefer actual cash spending because buildings cannot be maintained with an average estimate. Neither approach answers every question. A refurbishment can temporarily raise actual expenditure and depress AFFO below a normal-year level; a smoothed reserve can miss a coming replacement cycle. Compare several years of actual maintenance and leasing spending with the deductions used in AFFO. Explain any persistent gap using property age, lease terms, and disclosed projects.
Read definitions before rankings
Start with the issuer's net-income reconciliation, then read every footnote attached to AFFO. Compare the latest definition with the prior year's definition, not just the numbers. Check whether joint ventures, preferred dividends, and diluted shares are treated consistently. Return to the cash-flow statement to identify expenditures outside the measure and to the liquidity section for funding commitments. A cross-company table should include a definitions column. When material adjustments differ, compare your own clearly labeled sensitivity calculations instead of presenting the headline ratios as perfectly equivalent.
A common mistake
A lower published AFFO payout ratio can result from a more permissive adjustment policy rather than a safer dividend.
What to check in the disclosures
- Copy the issuer's exact definition.
- Identify recurring costs added back.
- Compare maintenance deductions with actual spending.
- Calculate a conservative alternative.
