Revenue Recognition The Companys leases are accounted for as operating leases. Certain leases provide for tenant occupancy during periods for which no rent is due and/or for increases or decreases in the minimum lease payments over the terms of the leases. Revenue is recognized on a straight-line basis over the terms of the individual leases. Revenue recognition under a lease begins when the tenant takes possession of or controls the physical use of the leased space. When the Company acquires a property, the term of existing leases is considered to commence as of the acquisition date for the purposes of this calculation. The Companys accrued rents are included in accrued rent and accounts receivable, net, on the accompanying consolidated balance sheets. The Company will defer the recognition of contingent rental income, such as percentage rents, until the specific target that triggers the contingent rental income is achieved. Additionally, cost recoveries from tenants are included in the Tenant Reimbursement and Other Revenues line item in the consolidated statements of operations in the period the related costs are incurred. As of January 1, 2018, the Company adopted ASU 2014-09, "Revenue from Contracts with Customers," (ASU 2014-09) which amends the guidance for revenue recognition to eliminate the industry-specific revenue recognition guidance and replace it with a principle based approach for determining revenue recognition. The Company adopted ASU 2014-09 effective January 1, 2018 using the modified retrospective approach and the adoption of this guidance did not have a material impact on the consolidated financial statements. The Companys revenue is primarily derived from leasing activities, which is specifically excluded from ASU 2014-09. The Companys other revenue is comprised of tenant reimbursements for real estate taxes, insurance, common area maintenance, and operating expenses. Reimbursements from real estate taxes and certain other expenses are also excluded from of ASU 2014-09.
