Revenue Recognition In addition to our lease-related revenue, we also earn fee revenues by providing services to the Managed Funds. These fees are accounted for within the scope of ASC Topic 606, Revenue from Contracts with Customers (ASC 606), and are recorded as Fees and Management Income on the consolidated statements of operations. We provide services to the Managed Funds, all of which are considered related parties. These services primarily include asset acquisition and disposition services, asset management, operating and leasing of properties, construction management, and other general and administrative responsibilities. These services are currently provided under various combinations of advisory agreements, property management agreements, and other service agreements (the Management Agreements). The wide variety of duties within the Management Agreements makes determining the performance obligations within the contracts a matter of judgment. We have concluded that each of the separately disclosed fee types in the below table represents a separate performance obligation within the Management Agreements. The table below shows the most significant of these fee types in the Management Agreements: Fee Performance Obligation Satisfied Form and Timing of Payment Description Asset Management Over time In cash and/or ownership units, monthly Because each increment of service is distinct, although substantially the same, revenue is recognized at the end of each reporting period based upon asset base and the applicable rate. Property Management Over time In cash, monthly Because each increment of service is distinct, although substantially the same, revenue is recognized at the end of each month based on a percentage of the properties cash receipts. Leasing Commissions Point in time (upon close of a transaction) In cash, upon completion Revenue is recognized in an amount equal to the fees charged by unaffiliated persons rendering comparable services in the same geographic location. Construction Management Point in time (upon close of a project) In cash, upon completion Revenue is recognized in an amount equal to the fees charged by unaffiliated persons rendering comparable services in the same geographic location. Acquisition/Disposition Point in time (upon close of a transaction) In cash, upon close of the transaction Revenue is recognized based on a percentage of the purchase price or disposition price of the property acquired or sold. Due to the nature of the services being provided under our Management Agreements, each performance obligation has a variable component. Therefore, when we determine the transaction price for the contracts, we are required to constrain our estimate to an amount that is not probable of significant revenue reversal. For most of these fee types, such as acquisition fees and leasing commissions, compensation only occurs if a transaction takes place and the amount of compensation is dependent upon the terms of the transaction. For our property and asset management fees, due to the large number and broad range of possible consideration amounts, we calculate the amount earned at the end of each month. In addition to the fees listed above, certain of our Management Agreements include the potential for additional revenues if certain market conditions are in place or certain events take place. We have not recognized revenue related to these fees, nor will we until it is no longer highly probable that there would be a material reversal of revenue. Additionally, effective January 1, 2018, sales or transfers to non-customers of non-financial assets or in substance non-financial assets that do not meet the definition of a business are accounted for within the scope of ASC Topic 610-20, Other IncomeGains and Losses from the Derecognition of Nonfinancial Assets (ASC 610-20). Generally, our sales of real estate would be considered a sale of a non-financial asset as defined by ASC 610-20. Under ASC 610-20, if we determine we do not have a controlling financial interest in the entity that holds the asset and the arrangement meets the criteria to be accounted for as a contract, we would de-recognize the asset and recognize a gain or loss on the sale of the real estate when control of the underlying asset transfers to the buyer. Further, we may defer a tax gain through an Internal Revenue Code (the Code) Section 1031 like-kind exchange by purchasing another property within a specified time period.
