Revenue from Contract with Customer [Abstract]

Our rental revenues include revenues from the leasing of space to tenants at our properties and revenues from parking and tenant services. We have the following revenue recognition policies:

•

Lease revenues from the leasing of space to tenants at our properties. Revenues derived from base rent are recognized over the non-cancelable term of the related leases on a straight-line basis which includes the effects of rent steps and rent abatements. We commence rental revenue recognition when the underlying asset is available for use by the lessee. In addition, in circumstances where we provide a tenant improvement allowance for improvements that are owned by the tenant, we recognize the allowance as a reduction of rental revenue on a straight-line basis over the term of the lease. Revenue derived from the reimbursement of real estate taxes, insurance expenses and common area maintenance expenses are generally recognized in the same period as the related expenses are incurred. As lessor, we have elected to combine the lease components (base and variable rent), non-lease components (reimbursements of common area maintenance expenses) and reimbursement of real estate taxes and insurance expenses from our operating lease agreements and account for the components as a single lease component in accordance with ASC 842.


•	Parking revenue arising from the rental of parking spaces at our properties. This income is recognized as the services are transferred in accordance with ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”).


•	Tenant services is revenue arising from sub-metered electric, elevator and other services provided to tenants at their request. This revenue is recognized as the services are transferred in accordance with ASC 606.
