Portfolio Occupancy vs Committed Occupancy (REIT) Singapore
Portfolio occupancy measures the percentage of a REIT’s total leasable area that is physically occupied and generating rent as of the reporting date, while committed occupancy includes both currently leased space and space covered by signed leases that have not yet commenced, giving a forward-looking view of near-term occupancy.

Key Takeaways
- Portfolio occupancy is a snapshot of physically tenanted space at a specific reporting date, based on leases that have already commenced.
- Committed occupancy adds signed-but-not-yet-started leases on top of portfolio occupancy, offering investors a preview of where occupancy is heading.
- A meaningful gap between committed and portfolio occupancy signals incoming positive momentum, since new tenants have already signed but have not yet moved in.
- Singapore REITs disclose both figures in quarterly and semi-annual results, most prominently for office, retail, and industrial trusts where fit-out periods between signing and move-in can span months.
- Investors should read occupancy trends alongside rental reversion and lease expiry data, since a high occupancy figure alone does not indicate whether rents are rising or falling.
What Is Portfolio Occupancy vs Committed Occupancy?
Occupancy is one of the most closely watched operating metrics in S-REIT quarterly and semi-annual results, since it directly drives rental income — the core revenue line for virtually every Singapore-listed REIT. However, S-REITs typically disclose not one but two distinct occupancy figures, and conflating them can lead investors to misread a REIT’s true operating momentum. Portfolio occupancy (sometimes simply called "occupancy" in headline commentary) measures the proportion of a REIT’s total net lettable area (NLA) that is currently leased and generating rental income as of the reporting date. It is a backward-looking, as-of-today snapshot: if a tenant has signed a lease but has not yet moved in and started paying rent, that space is not counted in portfolio occupancy. Committed occupancy takes portfolio occupancy and adds any additional space covered by leases that have been signed but have not yet commenced — for example, a retail unit where a new tenant has executed the lease agreement but is still completing renovation and fit-out before opening. This makes committed occupancy a forward-looking figure that gives investors visibility into occupancy levels a REIT expects to report in coming quarters, assuming those committed leases proceed as signed.
How Does It Work in Singapore?
The gap between portfolio occupancy and committed occupancy typically arises from the practical lag between signing a lease and a tenant actually opening for business. This lag varies significantly by property sub-sector: retail malls often see the longest fit-out periods, since tenants may need several months to build out a restaurant or specialty store, whereas industrial and logistics properties — often leased with minimal tenant improvement work — tend to show a smaller gap between committed and portfolio occupancy. Office REITs sit somewhere in between, with fit-out periods depending heavily on the scale of the tenant’s build-out requirements. A REIT manager highlighting a large positive gap between committed and portfolio occupancy in results commentary is typically signalling that occupancy (and by extension, rental income) is expected to improve in upcoming quarters as those committed leases commence and start contributing rent. Conversely, if committed occupancy is flat or only marginally above portfolio occupancy, it may suggest the REIT has limited near-term leasing momentum in the pipeline, which investors sometimes weigh alongside other forward indicators such as the weighted average lease expiry (WALE) and upcoming lease expiry schedule to assess overall demand trends. It’s worth noting that neither figure by itself indicates whether rents on those leases are rising or falling — that is a separate metric, typically disclosed as rental reversion, and a REIT can show strong occupancy while still reporting negative rental reversion if new and renewed leases are signed at lower rates than expiring ones.
Example
Suppose a hypothetical Singapore retail REIT reports portfolio occupancy of 96.5% and committed occupancy of 98.2% for its total net lettable area at the end of a quarter. The 1.7 percentage point gap represents space where new tenants have already signed leases but have not yet opened their stores — commonly because they are still completing renovation, obtaining licences, or preparing inventory. If those committed leases proceed as expected and the tenants open on schedule over the following one to two quarters, portfolio occupancy in the REIT’s next reporting period would be expected to rise toward that 98.2% committed figure, assuming no other leases expire or are terminated in the interim. By contrast, if the REIT’s portfolio occupancy and committed occupancy are both reported at 96.5% — identical, with no gap — this signals that there is currently no meaningful pipeline of signed-but-not-yet-started leases, which some investors interpret as a sign of slower near-term leasing momentum, though it could equally reflect an already very tightly leased asset with little available space to lease out in the first place.
Advantages
Committed occupancy offers forward visibility that portfolio occupancy alone cannot. By capturing signed-but-not-started leases, committed occupancy helps investors anticipate near-term income trends before they show up in reported portfolio occupancy or DPU.
Comparing both figures over time reveals leasing momentum. A widening gap between committed and portfolio occupancy across consecutive quarters can indicate accelerating leasing activity, while a narrowing gap can indicate slowing momentum.
Both metrics together provide a more complete operating picture. Relying on portfolio occupancy alone risks understating near-term income potential, while relying on committed occupancy alone risks overstating current cash-generating capacity.
Risks and Limitations
Committed leases are not guaranteed to commence as planned. Signed leases can occasionally fall through before commencement due to tenant financial difficulties, delayed licensing, or other disruptions, meaning committed occupancy is not a certainty.
A high occupancy figure does not indicate rental income direction. Both portfolio and committed occupancy measure leased space, not rental rates — a REIT can report high, stable occupancy while still experiencing negative rental reversion if new leases are signed at lower rates than expiring ones.
Occupancy figures can mask sub-portfolio weakness. A REIT’s blended portfolio occupancy figure can obscure meaningfully weaker occupancy in a specific property or geographic segment, which only becomes visible when reviewing segment-level disclosures.
Definitions can vary slightly in how sub-sectors report occupancy. While the general concepts of portfolio and committed occupancy are broadly consistent across S-REITs, exact treatment of factors like car park space, common areas, or master-leased blocks can differ between REIT managers, so like-for-like comparisons across REITs should be made carefully.
Portfolio Occupancy vs Committed Occupancy
| Dimension | Portfolio Occupancy | Committed Occupancy |
|---|---|---|
| What it measures | Space physically leased and generating rent today | Portfolio occupancy plus signed-but-not-started leases |
| Time orientation | Backward-looking / current snapshot | Forward-looking indicator |
| Reflects rental income already earned? | Yes, for currently leased space | Only partially — not-yet-commenced leases aren’t earning rent yet |
| Best used for | Assessing current income-generating capacity | Anticipating near-term occupancy and income trends |
| Typical gap size | N/A (baseline) | Larger in retail (longer fit-out), smaller in industrial/logistics |

The Bottom Line
For Singapore REIT investors, portfolio occupancy tells you what is generating rent today, while committed occupancy hints at where that figure is heading next. Reading both together — alongside rental reversion and lease expiry data — gives a far more complete picture than relying on either metric alone.
Frequently Asked Questions
Which occupancy figure is more important for investors to watch?
Neither figure alone tells the full story — portfolio occupancy shows current income-generating capacity, while committed occupancy shows near-term momentum. Watching the gap between them over consecutive quarters is often more informative than either figure in isolation.
Why is the gap between committed and portfolio occupancy larger for retail REITs than industrial REITs?
Retail tenants typically require longer renovation and fit-out periods before opening, creating a larger lag between lease signing and lease commencement, whereas industrial and logistics tenants often move in with minimal fit-out work.
Can committed occupancy ever be lower than portfolio occupancy?
In practice this is uncommon since committed occupancy is generally defined to include portfolio occupancy plus additional signed-but-not-started leases, meaning committed occupancy is typically equal to or higher than portfolio occupancy at any given reporting date.
Does high committed occupancy guarantee higher future DPU?
Not necessarily — DPU also depends on the rental rates those committed leases were signed at, financing costs, and any capital expenditure or unit issuance the REIT undertakes, so occupancy alone is only one input among several.
How often do S-REITs report portfolio and committed occupancy?
Most S-REITs disclose both figures in their quarterly business updates and semi-annual or annual financial results, alongside other operating metrics like WALE and rental reversion.
Do all REIT sub-sectors show a similar gap between committed and portfolio occupancy?
No. The gap tends to be widest for retail REITs, where tenants often need several months for renovation and fit-out before opening, more moderate for office REITs depending on the scale of tenant build-outs, and narrowest for industrial and logistics REITs, where tenants typically move in with minimal fit-out work required.
Where can I find a specific S-REIT's portfolio and committed occupancy figures?
Both figures are typically disclosed in the REIT’s quarterly business update or semi-annual/annual results presentation, usually available on the REIT manager’s investor relations webpage or via SGX announcements, alongside other operating metrics like WALE and rental reversion.
