FFO, AFFO and Financial Analysis of REITs
Traditional profit metrics (Net Income, EPS) are not applicable for analyzing REITs due to the significant influence of non-cash depreciation. The REIT industry has developed specific metrics—FFO (Funds From Operations) and AFFO (Adjusted FFO)—which better reflect operational cash flow and the ability to pay dividends.
Why Net Income Doesn’t Work for REITs
Real estate is depreciated under GAAP over 27.5–39 years (depending on type), although actual property values often rise. This creates a distortion:
Example: Office Building
| Indicator | Year 1 | Year 10 |
|---|---|---|
| Purchase Price | $100M | $100M |
| Accumulated Depreciation (39y) | $2.6M | $25.6M |
| Book Value | $97.4M | $74.4M |
| Market Value (2% appreciation) | $102M | $122M |
| Gap | $4.6M | $47.6M |
Net Income understates actual profitability due to the depreciation charge, which does not reflect economic reality.
FFO: Standard Definition (NAREIT)
FFO = Net Income + Depreciation & Amortization - Gains on Property Sales + Losses on Property Sales + Impairments
FFO Components
| Component | Logic | Add/Subtract |
|---|---|---|
| Net Income | Starting point (GAAP) | Base |
| Real Estate Depreciation | Non-cash expense, doesn’t reflect reality | + Add back |
| Amortization of RE intangibles | Above/below market leases, lease costs | + Add back |
| Gains on Property Sales | Non-recurring, distorts operating results | – Subtract |
| Losses on Property Sales | Non-recurring | + Add back |
| Impairments | Non-cash write-downs | + Add back |
FFO Calculation: Practical Example
| Indicator | Industrial REIT | Office REIT |
|---|---|---|
| Net Income | $150M | $80M |
| + Real Estate Depreciation | $120M | $95M |
| + Amortization | $15M | $12M |
| – Gains on Sales | ($25M) | ($5M) |
| + Impairment | $0 | $30M |
| FFO | $260M | $212M |
| Shares Outstanding | 100M | 80M |
| FFO/share | $2.60 | $2.65 |
AFFO: More Precise Metric
FFO overstates sustainable cash flow, as it does not account for capital expenditures required to maintain properties. AFFO (Adjusted FFO) corrects for this:
AFFO = FFO - Recurring CapEx - Straight-Line Rent Adjustment - Stock Compensation + Other Adjustments
AFFO Components
| Component | Description | Typical Size |
|---|---|---|
| Maintenance CapEx | Roofs, HVAC, elevators, parking lots | 5–15% of NOI |
| Tenant Improvements (TI) | Buildout for new tenants | $5–50/sq ft (office) |
| Leasing Commissions (LC) | Broker commission for leasing | 3–6% of lease value |
| Straight-Line Rent | GAAP recognizes rent evenly; cash differs | Varies |
| Stock Compensation | Non-cash expense | 2–5% of FFO |
AFFO Calculation: Continuing the Example
| Indicator | Industrial REIT | Office REIT |
|---|---|---|
| FFO | $260M | $212M |
| – Maintenance CapEx | ($20M) | ($25M) |
| – Tenant Improvements | ($15M) | ($40M) |
| – Leasing Commissions | ($8M) | ($18M) |
| – Straight-Line Rent Adj. | ($10M) | ($8M) |
| + Stock Comp Add-back | $5M | $4M |
| AFFO | $212M | $125M |
| AFFO/share | $2.12 | $1.56 |
| AFFO/FFO ratio | 81.5% | 59.0% |
Conclusion: The Office REIT looks attractive by FFO, but AFFO shows a much lower sustainable cash flow due to high TI/LC.
Key REIT Multiples
| Multiple | Formula | Interpretation | Typical Range |
|---|---|---|---|
| P/FFO | Price / FFO per share | Analog of P/E | 12–20x |
| P/AFFO | Price / AFFO per share | More precise P/E | 14–25x |
| EV/EBITDA | Enterprise Value / EBITDA | Capital-agnostic | 15–25x |
| P/NAV | Price / Net Asset Value | Premium/Discount | 0.8–1.2x |
| Dividend Yield | Annual Dividend / Price | Income return | 3–6% |
| AFFO Payout Ratio | Dividend / AFFO | Sustainability | 70–90% |
Sector Multiples (2024)
| Sector | P/FFO | P/NAV | Div Yield | AFFO Payout |
|---|---|---|---|---|
| Industrial | 22x | 1.05x | 2.8% | 65% |
| Data Centers | 25x | 1.15x | 2.5% | 70% |
| Residential | 18x | 0.95x | 3.5% | 75% |
| Healthcare | 15x | 0.90x | 5.0% | 85% |
| Retail (Net Lease) | 14x | 0.95x | 5.5% | 80% |
| Office | 10x | 0.65x | 7.0% | 90%+ |
| Cell Towers | 24x | N/A | 2.8% | 60% |
FFO Quality: Red Flags
Not all FFOs are created equal. The CIO must analyze quality:
Warning Signs
| Red Flag | Why This Is a Problem | How to Check AFFO |
|---|---|---|
| High CapEx, unsustainable dividends | AFFO/FFO ratio | |
| Straight-line rent >> Cash rent | Aggressive accounting, cash will be lower | Check cash flow statement |
| Rising occupancy, falling NOI | Rent concessions, below-market leases | Same-store NOI trend |
| External management | Conflicts of interest | Fee structure in filings |
| High payout ratio (>100%) | Dividend funded by debt/asset sales | Div/AFFO, debt trends |
| Frequent equity issuance | Dilution, dependency on capital markets | Share count growth |
REIT Comparison: Case Study
| Metric | Prologis (PLD) | SL Green (SLG) | Interpretation |
|---|---|---|---|
| Sector | Industrial | NYC Office | — |
| Market Cap | $115B | $4B | Size difference |
| FFO/share (2024E) | $5.50 | $5.80 | Similar absolute |
| P/FFO | 23x | 8x | Market confidence gap |
| AFFO/FFO | 82% | 55% | CapEx burden |
| Dividend Yield | 2.8% | 8.5% | Risk premium |
| AFFO Payout | 65% | 120% | Sustainability concern |
| Debt/EBITDA | 4.5x | 8.5x | Leverage risk |
| Occupancy | 97.5% | 89% | Demand strength |
| Same-Store NOI Growth | +8% | –3% | Operational trend |
Conclusion: SLG’s higher yield is not an opportunity, but a risk premium. AFFO payout >100% signals a potential dividend cut.
Dividend Safety Analysis
Formula for assessing dividend sustainability:
Dividend Safety Score = (AFFO Payout ≤80%) × (Debt/EBITDA ≤6x) × (Interest Coverage ≥3x) × (Occupancy ≥93%)
Dividend Safety Tiers
| Tier | Criteria | Examples |
|---|---|---|
| Safe | Payout <80%, Debt/EBITDA <4x | Prologis, Equinix, Realty Income |
| Moderate | Payout 75–90%, D/EBITDA 5–6x | AvalonBay, Welltower |
| At Risk | Payout >90%, D/EBITDA >7x, Coverage | Some office REITs |
| Likely Cut | Payout >100%, negative FCF | Distressed situations |
Practical CIO Recommendations
- FFO is the starting point, not the finish:
- Always look at AFFO to understand sustainable cash flow
- Sector-specific norms: For office, AFFO/FFO = 60% is normal; for industrial, this is a red flag
- Payout ratio discipline: Avoid REITs with AFFO payout >90%—dividend is at risk
- Reconciliation review: Read FFO/AFFO reconciliation in earnings releases—companies may “hide” costs
- Peer comparison: P/FFO makes sense only in comparison with peers in the same sector
- NAV as anchor: P/NAV shows what the market “thinks” about management quality and growth prospects
