💡 Accountant's Note
In most commercial leases (especially retail, industrial, and office), the tenant pays BASE RENT plus a proportional share of the property's operating expenses — a system called 'net' or 'gross' leases with expense recoveries. Common Area Maintenance (CAM) reimbursements: the tenant pays for its proportional share of: (1) CAM costs — hallway maintenance, parking lot snow removal, landscaping, security, HVAC in common areas, (2) PROPERTY TAXES — tenant pays its pro-rata share of real estate taxes (based on leased square footage / total leasable square footage), (3) INSURANCE — property and liability insurance allocated to tenants. Billing mechanics: the landlord estimates the annual CAM costs at lease commencement, bills monthly estimates (1/12 of annual estimate), then reconciles actual to estimate at year-end (usually the following spring). Under ASC 842: tenant reimbursements are a component of the LEASE consideration — presented as RENTAL REVENUE (not separate 'other income'), because the reimbursements are payments for the lease. Triple-net leases (NNN): the tenant pays all three expense categories directly — the landlord doesn't collect or remit; only base rent flows to the landlord.
Practitioner & Systems Framework
💻 ERP Architecture
CAM management is one of the most operationally intensive functions in commercial real estate — particularly for retail REITs with hundreds of tenants. The annual CAM reconciliation process: (1) Compile actual operating expenses for the prior year, (2) Allocate to each tenant based on their lease's CAM provisions (some leases have caps on annual CAM increases, exclusions for specific cost categories, or pro-rata share adjustments), (3) Compare actual allocations to monthly estimates billed, (4) Issue CAM reconciliation billings for deficiencies or credits for overpayments. CAM disputes (tenants challenging the allocation) are common and may require adjustment of the revenue accrual.
⚠️ Audit Flags
CAM reimbursement audits test: (1) Are monthly CAM estimates reasonable relative to actual costs? Systematically over-estimating creates large year-end credits and distorts revenue recognition. (2) Year-end CAM reconciliation completeness — are all tenants reconciled? (3) Lease compliance — are CAM charges computed per each lease's specific provisions (caps, exclusions, pro-rata shares)? (4) Tenant disputes — are disputed CAM charges properly reserved? (5) CAM audit rights — many retail tenants have lease rights to audit the landlord's CAM calculations — are any audit results pending that might require revenue adjustments?
📄 Required Documentation
Lease agreements (CAM provisions, exclusions, caps, audit rights), monthly CAM estimate billing schedule, actual operating expense summary by category, CAM reconciliation calculations by tenant, year-end CAM billing/credit notices to tenants, dispute register (tenants contesting CAM charges), CAM audit correspondence, and revenue recognition policy for gross vs. net presentation of reimbursable expenses.
