Recovery of past CAM overcharges depends on your specific lease terms, including any audit rights deadlines or ‘binding and conclusive’ provisions, and on applicable state law. State statute of limitations periods apply to written contracts and range from 3 to 10 years; your actual lookback window may be shorter based on your lease. CAMAudit is a document analysis platform, not a law firm, and nothing on this site constitutes legal advice. Consult a licensed real estate attorney before initiating any dispute or legal proceeding.

How to verify my pro-rata share is calculated correctly

Verifying your pro-rata share requires two numbers: your leased square footage and the denominator your lease defines. The formula looks simple but the denominator definition is where errors hide. Anchor exclusions, management office exclusions, and variable versus fixed denominator definitions all affect the result. CAMAudit extracts the correct denominator from your lease and does the math.

TL;DR

A pro-rata error affects every line item in your reconciliation simultaneously; verifying it once catches overcharges across the entire CAM pool rather than one line at a time.

Who this is for

Tenants who want to understand the mechanics of their pro-rata share calculation or who have noticed that the percentage on their reconciliation differs from what their lease appears to require.

Who this is not for

Tenants with a negotiated fixed CAM amount that is not tied to a pro-rata formula, or tenants who have already confirmed their percentage with their landlord in writing.

What CAMAudit Checks in This Scenario

Rule 4

Pro-Rata Share Error

CAMAudit extracts your lease-defined pro-rata formula, applies it to the figures in your reconciliation, and flags any discrepancy between your calculated share and the share used to bill you.

What to Do Next

  1. 1Find the pro-rata share definition in your lease, noting the exact numerator (your square footage) and denominator definition.
  2. 2Check whether the denominator is fixed (a stated number) or variable (actual building GLA at any given time).
  3. 3Verify whether any spaces are excluded from the denominator by lease terms, such as anchor tenant spaces or the management office.
  4. 4Calculate your expected pro-rata percentage using your lease-defined formula and compare it to the reconciliation.
  5. 5Upload your lease and reconciliation to CAMAudit to have the calculation verified automatically.
  6. 6If a discrepancy is found, request in writing that your landlord provide the exact denominator figure and square footage breakdown they used.
