CAM Audit Glossary: 35 Terms for Firms

The spreading of a large capital cost over its useful life, recognizing the expense in installments rather than all at once. In CAM, some leases permit landlords to amortize capital expenditures and pass the annual amortized portion through to tenants.

The contractual date by which a tenant must initiate a CAM audit after receiving the annual reconciliation statement. Missing the audit deadline can permanently bar the tenant from disputing that year's charges under a binding-and-conclusive clause.

A lease provision granting tenants the contractual right to inspect, review, and verify a landlord's CAM records and reconciliation calculations. Audit rights define the timeframe and procedure for initiating a CAM audit.

A reference year, typically the first year of the lease or year of building occupancy, used in gross leases to establish a baseline for operating expenses. Tenants pay only increases above the base year's actual costs in subsequent years.

A lease provision stating that a reconciliation statement becomes final and binding if the tenant does not object or initiate an audit within the specified audit window. These clauses are designed to give landlords finality on past reconciliations.

CAM charges means common area maintenance charges passed through to tenants for shared property costs such as parking lots, lobbies, landscaping, lighting, security, trash, and other spaces used by multiple occupants. CAM rent is separate from base rent in many NNN leases, billed as a monthly estimate, and corrected through an annual reconciliation.

A lease provision limiting the annual increase in controllable CAM expenses to a specified percentage (commonly 3 to 5%) or a fixed dollar amount. CAM caps protect tenants from runaway expense escalation in multi-year leases.

The annual process by which a landlord compares estimated CAM payments collected from tenants against actual CAM expenses incurred. Tenants receive a reconciliation statement showing whether they owe additional amounts or are due a refund.

A cost that extends the useful life of a building asset, improves its value, or replaces a major component, such as a new roof, HVAC system, or parking lot repaving. Capital expenditures are typically excluded from CAM in most commercial leases.

The shared portions of a commercial property accessible to all tenants and visitors: lobbies, hallways, parking lots, restrooms, elevators, and landscaped areas. Only legitimate common area expenses should be included in the CAM pool.

Operating expenses that are within the landlord's management control, such as landscaping, janitorial, security, and management fees. CAM caps typically apply only to controllable expenses, limiting annual increases.

An accounting method that spreads the cost of a long-lived asset over its useful life. Depreciation is almost universally excluded from commercial lease CAM definitions. Tenants pay for actual expenses, not accounting allocations.

A legal doctrine that delays the start of the statute of limitations until the injured party knew or reasonably should have known about the injury. In CAM disputes, the discovery rule may extend the lookback period when overcharges were concealed by the landlord.

A formal written notice specifying identified CAM overcharges, the legal and contractual basis for the dispute, and the amount requested for reimbursement. The dispute letter draft is typically the first step before legal action and the direct deliverable of a CAM audit engagement.

A dollar threshold, typically set at the base year's per-square-foot operating cost, above which the tenant pays their share of operating expense increases. The landlord covers all costs up to the expense stop; costs above it are passed through to tenants.

A lease structure in which the tenant pays a fixed rent and the landlord covers all or most operating expenses, including taxes, insurance, and maintenance. Gross leases typically have higher base rents but eliminate most variable expense exposure for tenants.

A lease mechanism that adjusts variable operating expenses upward to reflect what they would have been if the building were fully occupied (typically 95%). Gross-ups are designed to ensure each tenant pays their true share of common costs.

The multiplier applied to variable operating expenses to normalize them to a fully-occupied building level. Calculated as the target occupancy percentage divided by the actual occupancy percentage during the reconciliation period.

The process of verifying that insurance costs passed through to tenants in a CAM reconciliation match the coverage types and amounts permitted by the lease. Insurance overcharges typically arise when landlords include broader corporate coverage than the lease allows.

Internal costs of running the landlord's own business, such as corporate officer salaries, head office rent, leasing commissions, and marketing expenses, that are explicitly excluded from the recoverable expense pool in most commercial leases.

The number of prior lease years a tenant can audit or dispute under the lease terms and applicable statute of limitations. The lookback period determines how far back an overcharge recovery can extend.

Management fee means the commercial property management fee a landlord or manager bills for administering a property and its CAM or operating expense pool. Property management fees are usually calculated as a percentage of gross receipts, base rent, CAM costs, or total operating expenses, subject to the lease cap and fee base.

A hybrid lease structure between a full gross lease and a NNN lease, where specific operating expenses are negotiated between landlord and tenant. Some costs are included in base rent; others are billed separately as pass-throughs.

Operating expense means the recurring cost of running and maintaining a property or business in a commercial lease or accounting context. The operating expenses definition usually refers to recoverable OpEx such as CAM, real estate taxes, insurance, utilities, janitorial, repairs, and management fees, subject to lease exclusions.

The percentage of total CAM costs allocated to a specific tenant based on the ratio of their leased square footage to the total leasable area of the building or property. The denominator is a critical variable that landlords sometimes manipulate.

Prorated means using a daily rate or stated allocation method to divide a charge by the portion of time, space, or expense that applies. The prorated definition in a commercial lease usually matters when rent, CAM estimates, tax charges, insurance, or credits cover only part of a month, part of a lease year, or part of a tenant occupancy period.

Real estate tax means the property tax local governments assess against land, buildings, and other taxable real estate. In a commercial lease, real estate taxes are often passed through to tenants under a triple net lease, but only for the tax parcel, property period, and pro-rata share the lease permits.

Rent abatement means a period in a lease when the tenant pays reduced rent or no rent. In commercial leases, abated rent may be a free rent concession at lease commencement, a remedy after casualty damage, or a remedy after landlord default. The key issue is whether the abatement covers base rent only or also additional rent such as CAM, property taxes, insurance, utilities, and reconciliation true-ups.

Money collected from tenants and held by the landlord to fund future capital repairs and replacements. Unlike actual operating expenses, reserves are not incurred costs. Reserve contributions are generally excluded from CAM in most commercial leases.

The maximum period during which a legal claim can be filed after a cause of action arises. For CAM overcharge disputes, the statute of limitations for written contract claims typically ranges from 3 to 6 years depending on the state.

A lease structure in which the tenant pays base rent plus three additional cost categories: real estate taxes, building insurance, and CAM/operating expenses. In a true NNN lease, tenants bear nearly all property costs beyond mortgage debt service.

The year-end reconciliation payment or credit that results from comparing the tenant's estimated monthly CAM payments against actual annual CAM costs. A positive true-up means the tenant owes more; a negative true-up means the tenant is due a refund.

Operating expenses outside the landlord's management control, typically taxes, insurance, and utilities, that are excluded from CAM cap limitations and can be passed through in full regardless of annual increase amount.

The expected service life of a building component or asset, used to determine depreciation and amortization schedules. In CAM disputes, artificially short useful lives inflate amortized capital expense pass-throughs.

The percentage of a building's total leasable area that is vacant during the reconciliation period. The vacancy factor affects the gross-up calculation and, when misapplied, can inflate the CAM pool or each tenant's allocated share.
