The Company adopted the accounting guidance for revenue from contracts with customers (“Topic 606”) on January 1, 2018, using the modified retrospective approach and, therefore, the comparative information has not been adjusted. The guidance has been applied to contracts that were not completed as of the date of initial application. Most significantly for the real estate industry, leasing transactions are not within the scope of the new standard. A majority of the Company’s tenant-related revenue is recognized pursuant to lease agreements and is governed by the leasing guidance discussed in Note 1.

Historically, the majority of the Company’s lease commission revenue was recognized 50% upon lease execution and 50% upon tenant rent commencement. Upon adoption of Topic 606, lease commission revenue is generally recognized in its entirety upon lease execution. The impact of adopting Topic 606 on the Company’s consolidated financial statements with respect to the change in revenue recognition as related to lease commission revenue at January 1, 2018, and for the year ended December 31, 2018, was not material.

All revenue from contracts with customers meets the exemption criteria for variable consideration directly allocable to wholly unsatisfied performance obligations or unsatisfied promise within a series and, therefore, the Company does not disclose the value of transaction price allocated to unsatisfied performance obligations. There is no fixed consideration included in the transaction price for any of these revenues.
