Revenue Recognition All customer leases are classified as operating leases and minimum rents are recognized on a straight-line basis over the customers lease term. The excess of rents recognized over amounts contractually due pursuant to the underlying leases are included in deferred rent receivable and included in other assets in the condensed consolidated balance sheets. If a lease terminates prior to its stated expiration, the deferred rent receivable relating to that lease is written off as a reduction of rental revenue. When arrangements include multiple elements, the revenue associated with separate elements is allocated based on the relative fair values of those elements. The revenue associated with each element is then recognized as earned. Interconnection services and additional space services are considered as separate earnings processes that are provided and completed on a month-to-month basis and revenue is recognized in the period that services are performed. Customer set-up charges and utility installation fees are initially deferred and recognized over the term of the lease arrangement as revenue. Tenant reimbursements for real estate taxes, common area maintenance, and other recoverable costs are recognized as revenue in the period that the related expenses are incurred. Above-market and below-market lease intangibles that were acquired are amortized on a straight-line basis as decreases and increases, respectively, to rental revenue over the remaining noncancelable term of the underlying leases. For both the three months ended June 30, 2017, and 2016, the net effect of amortization of acquired above-market and below-market leases resulted in an increase to rental revenue of $0.1 million. For both the six months ended June 30, 2017, and 2016, the net effect of amortization of acquired above-market and below-market leases resulted in an increase to rental revenue of $0.3 million.
