Adjusted Funds From Operations (AFFO) is a key performance metric used to evaluate Real Estate Investment Trusts (REITs). Think of it as the refined, truer measure of a REIT’s cash-generating power. While its more famous cousin, Funds From Operations (FFO), provides a good starting point, AFFO goes a step further to give investors a clearer picture of the actual cash available to be paid out as dividends. How? It starts with FFO and then subtracts the recurring capital expenditures (CapEx) needed to maintain the properties in good working order—think new roofs, replaced HVAC systems, and fresh coats of paint. It also adjusts for non-cash accounting quirks like straight-line rent. In essence, AFFO represents the economic reality of a REIT's operations, showing the sustainable cash flow after all necessary maintenance costs are paid. For a value investor analyzing a REIT, AFFO is arguably the most important metric for assessing dividend safety and underlying value.
To truly appreciate AFFO, you have to understand the metric it improves upon: FFO. FFO is calculated by taking a REIT's net income and adding back depreciation, which is a non-cash expense. This makes sense for real estate, as well-maintained buildings often appreciate in value over time, unlike factory machinery. However, FFO has a glaring blind spot: it completely ignores the real cash that must be spent every year to keep those buildings in good shape. Properties don't maintain themselves for free. This is where AFFO shines. It acknowledges that a portion of the cash flow must be reinvested back into the properties just to keep them competitive and functional. Think of it this way:
By subtracting these maintenance CapEx costs, AFFO provides a much more conservative and realistic measure of a REIT's ability to pay dividends.
While there is no single, regulator-mandated formula for AFFO (a crucial point to remember!), the generally accepted calculation looks something like this: AFFO = FFO - Recurring Capital Expenditures - Straight-line Rent Adjustments +/- Other Items Let’s break that down:
A Word of Warning: Because the formula isn't standardized, you must check a REIT's quarterly or annual report. They will usually provide a reconciliation table showing exactly how they calculated their AFFO. Always compare apples to apples when looking at different REITs.
For value-focused investors, AFFO is the Swiss Army knife for analyzing REITs. Here are its primary uses:
This is AFFO's killer app. By comparing the total dividends paid to the AFFO generated, you can calculate the AFFO Payout Ratio. AFFO Payout Ratio = Total Dividends Paid / Adjusted Funds From Operations A ratio consistently below 100% (ideally in the 75-90% range) indicates the dividend is well-covered by cash flow and is likely sustainable. A ratio creeping above 100% is a major red flag, suggesting the REIT is paying out more cash than it’s generating and may have to dip into debt or cut the dividend.
Forget the standard Price/Earnings (P/E) ratio when it comes to REITs. The far superior metric is the Price/AFFO ratio. It tells you how much you are paying for each dollar of sustainable cash flow. A lower P/AFFO multiple can suggest a REIT is undervalued compared to its peers, but as always, it should be considered alongside other factors like debt levels, property quality, and management competence.
Tracking the growth of AFFO per share over several years provides insight into management's ability to create real, sustainable value for shareholders. Is the company acquiring properties that generate strong cash flow? Is it managing expenses effectively? Consistent AFFO per share growth is a hallmark of a well-run REIT.
