Definition: Income received from the tenant as a reimbursement of expenses paid by the landlord. In a lease, an expense reimbursement clause stipulates that some or all of the operating expenses paid by the landlord are recoverable (reimbursables) from the tenant; also called expense recoveries, reimbursables, billables or pass-throughs. Recoverable expenses are deducted as expenses and (offsetting) recoveries are treated as separate revenue items in income and expense statements.
