3.	REVENUE RECOGNITION

We earn revenue from the following:


•	Leasing;


•	Capital Markets;


•	Property & Facility Management;


•	Project & Development Services;


•	Advisory, Consulting and Other; and


•	LaSalle.

Leasing

Leasing revenue is earned from brokerage commissions as we represent tenants and/or landlords in connection with real estate leases. Our performance obligation is to facilitate the execution of a lease agreement which is satisfied at a point in time, upon lease execution. Generally, we are either entitled to the full consideration upon lease execution or in part upon lease execution with the remainder upon the occurrence of a future event outside of our control (e.g. occupancy, lease commencement, or rent commencement). The majority of the events that preclude our entitlement to the full consideration upon lease execution are considered to be “normal course of business” and, as a result, do not result in a constraint upon the recognition of revenue. In the infrequent instance our fee entitlement in a contract with a customer is predicated on the occurrence of future events that are uncertain of occurring, we constrain the recognition of revenue until the uncertainty is resolved or the future event occurs. Generally, less than 5% of our Leasing revenue recognized had previously been constrained.

Capital Markets

Capital Markets provides brokerage and other services for capital transactions, such as real estate sales or loan originations and refinancings. Our performance obligation is to facilitate the execution of capital transactions and we are generally entitled to the full consideration at the point in time upon which our performance obligation is satisfied, at which time we recognize revenue.

Property & Facility Management

Property Management provides on-site day-to-day real estate management services for owners of office, industrial, retail, multifamily residential and specialty properties, representing a series of daily performance obligations delivered over time. Pricing is generally in the form of a monthly management fee based upon property-level cash receipts, square footage under management or some other variable metric.

Although we are principal in limited situations, we generally act as agent on behalf of our Property Management clients in relation to third party vendors and subcontractors engaged to deliver operational services to our clients' properties. In these situations, we do not control the services provided by third party vendors and subcontractors prior to the transfer of the services to the client. As a result, the costs incurred on behalf of clients, along with the corresponding reimbursement revenue, are presented net on our Condensed Consolidated Statements of Comprehensive Income.

Facilities Management primarily provides comprehensive, on-site day-to-day real estate management services to corporations and institutions across a broad range of industries that outsource the management of the real estate they occupy, representing a series of daily performance obligations delivered over time. Pricing generally includes an annual management fee paid quarterly and, in many instances, an annual incentive fee.

Although we may act as agent on behalf of our clients with respect to certain mandates, we generally act as principal for our Facilities Management contracts with respect to third party vendors and subcontractors engaged to deliver operational services to our clients' facilities. In these situations, we control the services provided by such third party vendors and subcontractors prior to the transfer of the services to the client. As a result, the costs incurred on behalf of our clients, along with the corresponding reimbursement revenue of an equal amount, are presented gross on our Condensed Consolidated Statements of Comprehensive Income.

Project & Development Services

Project & Development Services provides short-term construction-related services ranging from general contracting to project management for owners and occupiers of real estate. Depending on the terms of our engagement, our performance obligation is either to arrange for the completion of a project or to assume responsibility for completing a project on behalf of a client. Our obligations to clients are satisfied over time due to the continuous transfer of control of the underlying asset. Therefore, we recognize revenue over time, primarily using input measures (e.g. to-date costs incurred relative to total estimated costs at completion). Typically, we are entitled to consideration at distinct milestones over the term of an engagement.

For certain contracts, we control the services provided by third party vendors and subcontractors prior to transfer of the assets to the client. In these situations, the costs incurred on behalf of clients, along with the associated reimbursement revenue are presented gross on our Condensed Consolidated Statements of Comprehensive Income. For situations in which we act as agent on behalf of clients, costs incurred and the associated reimbursement revenue are presented net on our Condensed Consolidated Statements of Comprehensive Income.

Advisory, Consulting and Other

Advisory, Consulting and Other includes a variety of different service offerings, whereby our performance obligation is to provide services as specified in the contract. Occasionally, our entitlement to consideration is predicated on the occurrence of an event such as the delivery of a report for which client acceptance is required. However, except for event-driven point-in-time transactions, the majority of services provided within this service line are delivered over time due to the continuous transfer of control to our clients.

LaSalle

LaSalle provides real estate investment management services to clients and earns consideration in the form of advisory fees, transaction fees, and incentive fees. Typically, our performance obligation is to manage clients’ capital for a specified period of time and is delivered as a series of daily performance obligations over time. Revenue recognition for transaction and incentive fees is generally constrained until all contingencies have cleared due to the possibility of a significant reversal until completion of the events necessary to realize the associated consideration. Substantially all incentive fees recognized as revenue were previously constrained.

Contract Assets - Contract assets include amounts recognized as revenue for which we are not yet entitled to payment for reasons other than the passage of time, but that do not constrain revenue recognition. As of March 31, 2018 and December 31, 2017, we had $265.2 million and $236.0 million of contract assets, respectively, which are included in Short-term contract assets and Other assets on the Condensed Consolidated Balance Sheets.

Contract Liabilities - Contract liabilities include advance payments related to performance obligations that have not yet been satisfied. As of March 31, 2018 and December 31, 2017, we had $82.5 million and $73.7 million of contract liabilities, respectively, which are included in Short-term contract liabilities and deferred income on our Condensed Consolidated Balance Sheets. The significant majority of contract liabilities are recognized as revenue within 90 days.

Deferred Income - Deferred income includes payments received from customers for which we have satisfied our performance obligations but are not yet able to recognize the related revenue because of contractual requirements.

Remaining Performance Obligations - Remaining performance obligations represent the aggregate transaction prices for contracts where our performance obligations have not yet been satisfied. As of March 31, 2018, the aggregate amount of transaction price allocated to remaining performance obligations represented less than 5% of our total revenue. In accordance with ASC Topic 606, excluded from the total disclosed remaining performance obligations are (i) amounts attributable to contracts expected to be completed within 12 months and (ii) variable consideration for services performed as a series of daily performance obligations, such as facilities management, property management, and LaSalle contracts. Contracts within these businesses represent a significant portion of our contracts with customers not expected to be completed within 12 months.
