The reconciliation statement arrives as a PDF. It might be two pages or twelve. Either way, the task is the same. Figure out what it says. Decide whether the number makes sense. Find where it goes in the books. For more context, see positioning CAM advisory services. CAM is Common Area Maintenance.
This article walks through a CAM reconciliation statement section by section. It explains each part in plain words. It shows what to check before you code the payment.
CAM reconciliation: A CAM reconciliation is the annual settlement process in which the landlord compares the total Common Area Maintenance expenses stated for the building during the year to the estimated amounts the tenant paid monthly. The result is either a balance due from the tenant or a credit if estimates exceeded actual expenses. The landlord documents this calculation in a reconciliation statement delivered under the lease process.
The four sections of a reconciliation statement
Landlords use different formats. But almost every CAM reconciliation holds the same four pieces of information.
1. The total expense pool
This is the sum of the operating costs the landlord says prioritize for the building for the year. A clear reconciliation shows a table of categories with annual totals. It may list cleaning, landscaping, insurance, taxes, management fees, utilities, or repair lines. The lease decides which categories belong in the client''s pool.
The sum of those categories is the total pool. The pool is what the landlord says it spent. The next section sets how much of it this tenant owes.
If the statement shows only a total with no category breakdown, that is a flag. The detail is what lets you check whether excluded categories slipped into the pool. Request the backup detail when the client threshold or lease file calls for review before coding.
2. The tenant pro rata share
The pro rata share is the percent used to allocate the pool to one tenant. It comes from a formula in the lease. The most common version is:
Tenant rentable square footage divided by total leasable building square footage
The lease or abstract should show the tenant square footage and the building denominator. Use those two fields to recalculate the pro rata share. Then compare that percent to the statement before coding the true-up.
The statement usually states the pro rata share as a percent and shows the math. Confirm it against the lease abstract before you accept it. The denominator matters. Some leases use total leasable square footage. Others use occupied square footage, which leaves out vacant space. Some use total building square footage, which adds non-rentable areas like stairwells and mechanical rooms. A different denominator gives a different percent.
3. The estimated payments already made
The reconciliation capacity the tenant for the monthly CAM estimates paid during the year. This line should match the client''s payment history. That amount is subtracted from the allocated share.
Check this number against the payment history. Errors here are less common than pool errors, but they happen. A December payment the landlord has not yet applied makes the balance due look too large. Confirm the total against bank records or the accounts payable ledger.
4. The balance due or credit
The balance is the allocated share minus the estimated payments. The statement says whether the result is a bill or a credit. It should also state the due date or credit process.
If the share is less than the payments, the result is a credit. The lease says how the credit is handled. It may be refunded in cash, applied to future estimates, or applied to next month's rent.
What "backup" means and when to request it
The word backup comes up a lot with CAM reconciliations. It means the supporting documents behind the numbers on the statement.
For the expense pool, backup is the itemized list of operating expenses the landlord included. It might be a general ledger extract, a schedule of invoices, or a categorized expense report. Without it, you cannot verify the pool total.
For the pro rata share, backup is the floor plan or square footage certification. It documents the tenant and building square footage used in the math.
For the estimated payments, backup is the monthly CAM invoices or a payment history schedule.
Set a client threshold for when the firm requests detail before coding or payment. Check the lease and client file before framing the request.
The request does not have to feel like a fight. A short note to the property manager asking for the expense detail and square footage basis is routine. Keep a copy in the client file.
Sections that create confusion
Management fee. This line may sit in the pool as a percent of other operating costs. The lease usually states the allowed base and rate. Check the stated fee against the lease cap and the expense base used by the landlord.
Real estate taxes. Property taxes are often the largest single line in the pool. Some leases bill taxes apart from CAM as a separate line. Others fold them into the CAM total. Either way, the reconciliation should show taxes as a line. The amount should roughly match public tax records for the property.
Insurance. Building insurance is usually in the pool. The reconciliation shows an annual premium. If the premium jumped a lot year over year, the tenant can request the insurance certificate to confirm the increase.
Capital expenditures. Capital treatment is lease-specific. A roof replacement, an HVAC upgrade, or a parking lot resurfacing needs closer review before it flows through the operating pool. If a line looks unusually large or says "replacement" or "system upgrade," ask whether the lease allows that treatment.
Reading the statement when the format is non-standard
Reconciliation formats vary. The client may receive a clean PDF template, a spreadsheet, an Excel file, or a letter with numbers buried in the text. The content to review is the same.
Start by finding the four parts. Total pool, pro rata share percent, estimated payments, and the balance. Once you have those four numbers, the math is simple. Pool times share, minus estimates, equals the balance.
If a line says "admin fee," "asset management fee," or "oversight fee" apart from the management fee line, check whether it is counted twice. Similar labels can hide duplicate treatment if nobody compares the statement to the lease.
If the statement points to a lease abstract or a specific exhibit, pull that exhibit before you finalize the coding. Reconciliations sometimes use different square footage or pro rata figures than the current lease amendment. This happens most with long-term tenants who expanded or shrank their space.
Before coding the payment
At this stage, the bookkeeper confirms two things. The four core numbers agree with each other. The balance due matches the lease terms. Do this before the payment hits the books.
The accuracy question comes first. Is the number right? The accounting question comes second. Which account and which period? Both matter. Coding the right GL account with the wrong amount is still an error.
Set a threshold with the client. For any balance above it, review the reconciliation against the lease abstract and backup. The review may be quick for a clean statement. It may take longer when the file is missing detail or the lease language is unclear. The partner should document the result before the client pays or books the final entry.
