Revenue Recognition, Tenant Receivables and Allowance for Uncollectible Accounts The Company recognizes revenue in accordance with ASC 605, Revenue Recognition , or ASC 605. ASC 605 requires that all four of the following basic criteria be met before revenue is realized or realizable and earned: (1) there is persuasive evidence that an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the sellers price to the buyer is fixed and determinable; and (4) collectability is reasonably assured. In accordance with ASC 840, Leases , minimum rental revenue is recognized on a straight-line basis over the term of the related lease (including rent holidays). Differences between rental income recognized and amounts contractually due under the lease agreements are credited or charged to deferred rent receivable or deferred rent liability, as applicable. Tenant reimbursement revenue, which is comprised of additional amounts recoverable from tenants for common area maintenance expenses and certain other recoverable expenses, is recognized as revenue in the period in which the related expenses are incurred. Tenant reimbursements are recognized and presented in accordance with ASC Subtopic 605-45, Revenue RecognitionPrincipal Agent Consideration, or ASC 605-45. ASC 605-45 requires that these reimbursements be recorded on a gross basis, when the Company is the primary obligor with respect to purchasing goods and services from third-party suppliers and has discretion in selecting the supplier and has credit risk. Tenant receivables and unbilled deferred rent receivables are carried net of the allowances for uncollectible amounts. An allowance will be maintained for estimated losses resulting from the inability of certain tenants to meet the contractual obligations under their lease agreements. The Company also maintains an allowance for deferred rent receivables arising from the straight-lining of rents. The Companys determination of the adequacy of these allowances is based primarily upon evaluation
