A retail tenant's lease defined the denominator as gross leasable area excluding the anchor tenant's 85,000 square feet. The landlord's reconciliation applied a denominator that included the anchor space, reducing the denominator from 215,000 to 300,000 square feet and inflating every CAM line item by 40%. On a $50,000 total CAM bill, the mismatched denominator produced $20,000 in overcharges. CAMAudit flagged the anchor exclusion omission by comparing the lease definition against the percentage applied.

Allocation Methodology Mismatch: When the Landlord Uses the Wrong Sharing Formula
The correct allocation percentage flows directly from the denominator definition in the lease. A mismatched denominator can inflate the tenant's share across every line item in the reconciliation.
If the landlord allocates costs by rentable square footage but the lease requires allocation by leasable area excluding anchor tenants, a 40% denominator inflation can add $8,000 or more to a single year's CAM bill when every line item is recalculated against the wrong base.
What it checks
An allocation methodology mismatch occurs when the landlord distributes shared costs using a formula that differs from the one defined in the lease. Common allocation bases include rentable square footage, leasable area, gross leasable area excluding anchors, occupied area, and custom denominator definitions specific to the lease. When the methodology used in the reconciliation does not match the lease, the tenant may be over- or under-charged relative to their contractual obligation. This rule compares the allocation formula in the reconciliation statement against the tenant's lease to identify discrepancies in the denominator definition, the treatment of anchor space, vacant space, or excluded areas, and whether the percentage itself matches what the lease requires.
The logic
Allocation Methodology Mismatch in 3 passes
- 1
CAMAudit extracts the tenant pro-rata share percentage and denominator definition from the lease and compares it against the allocation percentage applied in the reconciliation statement.
- 2
CAMAudit flags inconsistencies where the denominator used in the reconciliation differs from the lease definition, where anchor space or excluded areas are treated differently than specified, or where the resulting percentage does not match the lease.
- 3
CAMAudit reports the lease-defined percentage alongside the percentage actually applied so the tenant can quantify the impact across all line items.

FAQ
Questions about allocation methodology mismatch
What is the most common allocation methodology error?
Including anchor tenant space in the denominator when the lease requires excluding it. Anchor exclusions are standard in retail leases and significantly affect the allocation percentage.
How does a firm verify the denominator used in a reconciliation?
Request a floor plan or rent roll showing the square footage breakdown used to calculate the pro-rata share. Compare the total building area, occupied area, and any excluded areas against the lease definition.
Can the allocation methodology change year to year?
The lease controls the methodology. Changes to the building (additions, demolitions, changes in anchor status) may affect the denominator, but the formula itself should not change unless the lease is amended.
What backup should a firm request to verify the allocation methodology?
Request the rent roll or building square footage schedule used to calculate pro-rata shares, the total rentable area and leasable area figures, a list of any excluded spaces (anchor tenants, vacant units, landlord-use areas), and the calculation showing how the pro-rata percentage was derived. Compare those figures against the denominator definition in the lease.
