Minimum annual 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 amount contractually due under the lease agreements are recorded as straight-line rent receivables. 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 recorded on a gross basis, as we are generally the primary obligor with respect to purchasing goods and services from third-party suppliers, have discretion in selecting the supplier, and have credit risk. We recognize lease termination fees when there is a signed termination letter agreement, all of the conditions of the agreement have been met, and the tenant is no longer occupying the property. Rental income is reported net of amortization of inducements. Effective January 1, 2018, with the adoption of Topic 606 and corresponding amendments, the revenue recognition process will be based on a five-step model to account for revenue arising from contracts with customers and supersedes most of the existing revenue recognition guidance. Topic 606 requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. As a REIT, our revenue is primarily generated through leasing contracts, which are excluded from Topic 606. The impact of Topic 606 will be concentrated in the recognition of our non-lease revenue streams.
