Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	1. Basis of Presentation Readers of this Quarterly Report on Form 10-Q (Quarterly Report) should refer to the audited financial statements and notes to consolidated financial statements of CBRE Group, Inc., a Delaware corporation (which may be referred to in these financial statements as “the company,” “we,” “us” and “our”), for the year ended December 31, 2017, which are included in our 2017 Annual Report on Form 10-K (2017 Annual Report), filed with the United States Securities and Exchange Commission (SEC) and also available on our website (www.cbre.com), since we have omitted from this Quarterly Report certain footnote disclosures which would substantially duplicate those contained in such audited financial statements. You should also refer to Note 2, Significant Accounting Policies, in the notes to consolidated financial statements in our 2017 Annual Report for further discussion of our significant accounting policies and estimates. The accompanying consolidated financial statements have been prepared in accordance with the rules applicable to quarterly reports on Form 10-Q and include all information and footnotes required for interim financial statement presentation, but do not include all disclosures required under accounting principles generally accepted in the United States (U.S.), or GAAP, for annual financial statements. In our opinion, all adjustments (consisting of normal recurring adjustments, except as otherwise noted) considered necessary for a fair presentation have been included. The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, and reported amounts of revenue and expenses. Such estimates include the value of goodwill, intangibles and other long-lived assets, real estate assets, accounts receivable, contract assets, investments in unconsolidated subsidiaries and assumptions used in the calculation of income taxes, retirement and other post-employment benefits, among others. These estimates and assumptions are based on our best judgment. We evaluate our estimates and assumptions on an ongoing basis using historical experience and other factors, including consideration of the current economic environment, and adjust such estimates and assumptions when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in these estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods. Certain restatements have been made to the 2017 financial statements to conform with the 2018 presentation in connection with our adoption of new revenue recognition guidance (as further described in notes 2, 3 and 12). In addition, certain reclassifications have been made to the 2017 financial statements to conform with the 2018 presentation. Such reclassifications primarily relate to the adoption of Accounting Standards Update (ASU) 2016‑01, ASU 2016-15 and ASU 2016-18 as further described in Note 3. The results of operations for the three and six months ended June 30, 2018 are not necessarily indicative of the results of operations to be expected for the year ending December 31, 2018.

Significant Accounting Policies

Significant Accounting Policies Update	6 Months Ended
	Jun. 30, 2018
Accounting Policies [Abstract]
Significant Accounting Policies Update	2. Significant Accounting Policies Update Revenue Recognition We account for revenue in accordance with Accounting Standards Codification (ASC) Topic 606, “ Revenue from Contracts with Customers Other Assets and Deferred Costs – Contracts with Customers The following is a description of principal activities – separated by reportable segments – from which we generate revenue. For more detailed information about our reportable segments, see Notes 12 and 13. The Americas, Europe, Middle East and Africa (EMEA), and Asia Pacific The Americas segment is our largest segment of operations and provides a comprehensive range of services throughout the United States (U.S.), in the largest regions of Canada and in key markets in Latin America. The primary services offered consist of the following: property leasing, property sales, mortgage services, appraisal and valuation, occupier outsourcing and property management services. Our EMEA and Asia Pacific segments generally provide services similar to the Americas business segment. The EMEA segment has operations primarily in Europe, while the Asia Pacific segment has operations in Asia, Australia and New Zealand. Property Leasing and Property Sales Through our Advisory & Transaction Services business line, we provide strategic advice and execution to owners, investors, and occupiers of real estate in connection with the leasing of office, industrial and retail space. We also offer clients fully integrated property sales services under the CBRE Capital Markets brand. We are compensated for our services in the form of a commission and, in some instances may earn various forms of variable incentive consideration. Our commission is paid upon the occurrence of certain contractual event(s) which may be contingent. For example, a portion of our leasing commission may be paid upon signing of the lease by the tenant, with the remaining paid upon occurrence of another future contingent event (e.g. payment of first month’s rent or tenant move-in). For sales, our commission is typically paid at the closing of the sale. We typically satisfy our performance obligation at a point in time when control is transferred; generally, at the time of the first contractual event where there is a present right to payment. We look to history, experience with a customer, and deal specific considerations to support our judgement that the second contingency (if applicable) will be met. Therefore, we typically accelerate the recognition of the revenue associated with the second contingent event. In addition to our commission, we may recognize other forms of variable consideration which can include, but are not limited to, commissions subject to concession or claw back and volume based discounts or rebates. We assess variable consideration on a contract by contract basis, and when appropriate, recognize revenue based on our assessment of the outcome (using the most likely outcome approach or weighted probability) and historical results, if comparable and representative. We recognize variable consideration if it is deemed probable that there will not be significant reversal in the future. Mortgage Originations and Loan Sales Under the CBRE Capital Markets brand, we offer clients fully integrated commercial mortgage and structured financing services. Fees from services within our mortgage brokerage business that are in the scope of Topic 606 include fees earned for the brokering of commercial mortgage loans primarily through relationships established with investment banking firms, national and regional banks, credit companies, insurance companies and pension funds. We are compensated for our brokerage services via a fee paid upon successful placement of a commercial mortgage borrower with a lender who will provide financing. The fee earned is contingent upon the funding of the loan. We typically satisfy our performance obligation when control is transferred at the point in time of the funding of the loan. We also earn fees from the origination and sale of commercial mortgage loans for which the company retains the servicing rights. These fees are governed by the “ Fair Value Measurements and Disclosures Transfers and Servicing Appraisal and Valuation We provide valuation services that include market-value appraisals, litigation support, discounted cash flow analyses, feasibility studies as well as consulting services such as property condition reports, hotel advisory and environmental consulting. We are compensated for valuation services in the form of a fee, which is payable on the occurrence of certain events (e.g., a portion on the delivery of a draft report with the remaining on the delivery of the final report). For consulting services, we may be paid based on the occurrence of time or event-based milestones (such as the delivery of draft reports). We typically satisfy our performance obligation as services are rendered over time. Occupier Outsourcing Services We provide a broad suite of services to occupiers of real estate, including facilities management, project management, transaction management and strategic consulting. We report facilities and project management as well as strategic consulting activities in our occupier outsourcing revenue line and transaction management in our lease and sales revenue lines. Facilities management involves the day-to-day management of client-occupied space and includes headquarter buildings, regional offices, administrative offices, data centers and other critical facilities, manufacturing and laboratory facilities, distribution facilities and retail space. Contracts for facilities management services are often structured so we are reimbursed for client-dedicated personnel costs and subcontracted vendor costs as well as associated overhead expenses plus a monthly fee, and, in some cases, annual incentives tied to agreed-upon performance targets, with any penalties typically capped. Facilities management services represent a series of distinct daily services rendered over time. Project management services are often provided on a portfolio wide or programmatic basis. Revenues from project management services generally includes fixed management fees, variable fees, and incentive fees if certain agreed-upon performance targets are met. Revenues from project management may also include reimbursement of payroll and related costs for personnel providing the services and subcontracted vendor costs. Project management services represent a series of distinct daily services rendered over time. The amount of revenue recognized is presented gross for any services provided by our employees, as we control them. This is evidenced by our obligation for their performance and our ability to direct and redirect their work, as well as negotiate the value of such services. The amount of revenue recognized related to the majority of facilities management contracts and certain project management arrangements is presented gross (with offsetting expense recorded in cost of services) for reimbursements of costs of third-party services because we control those services that are delivered to the client. In the instances when we do not control third-party services delivered to the client, we report revenues net of the third-party reimbursements. In addition to our management fee, we receive various types of variable consideration which can include, but is not limited to; key performance indicator bonuses or penalties which may be linked to subcontractor performance, gross maximum price, glidepaths, savings guarantees, shared savings, or fixed fee structures. We assess variable consideration on a contract by contract basis, and when appropriate, recognize revenue based on our assessment of the outcome (using the most likely outcome approach or weighted probability) and historical results, if comparable and representative. Using management assessment and historical results and statistics, we accelerate revenue if it is deemed probable there will not be significant reversal in the future. Property Management We provide property management services on a contractual basis for owners of and investors in office, industrial and retail properties. These services include construction management, marketing, building engineering, accounting and financial services. We are compensated for our services through a monthly management fee earned based on either a specified percentage of the monthly rental income, rental receipts generated from the property under management or a fixed fee. We are also often reimbursed for our administrative and payroll costs directly attributable to the properties under management. Property management services represent a series of distinct daily services rendered over time. The amount of revenue recognized is presented gross for any services provided by our employees, as we control them. We generally do not control third-party services delivered to property management clients. As such, we report revenues net of third-party reimbursements. Global Investment Management Our Global Investment Management business segment provides investment management services to pension funds, insurance companies, sovereign wealth funds, foundations, endowments and other institutional investors seeking to generate returns and diversification through investment in real estate. We sponsor investment programs that span the risk/return spectrum in: North America, Europe, Asia and Australia. We are typically compensated in the form of a base management fee, disposition fees, acquisition fees and incentive fees in the form of performance fees or carried interest based on fund type (open or closed ended, respectively). For the base management fee, we typically satisfy the performance obligation as service is rendered over time pursuant to the series guidance. For acquisition and disposition services, we typically satisfy the performance obligation at a point in time (at acquisition or upon disposition). For contracts with contingent fees, including performance fees, incentive fees and carried interest, we assess variable consideration on a contract by contract basis, and when appropriate, recognize revenue based on our assessment of the outcome (using the most likely outcome approach or weighted probability) and historical results, if comparable and representative. Revenue associated with performance fees and carried interest are typically constrained due to volatility in the real estate market, a broad range of possible outcomes, and other factors in the market that are outside of our control. Development Services Our Development Services business segment consists of real estate development and investment activities primarily in the United States to users of and investors in commercial real estate, as well as for our own account. We pursue opportunistic, risk-mitigated development and investment in commercial real estate across a wide spectrum of property types, including: industrial, office and retail properties; healthcare facilities of all types (medical office buildings, hospitals and ambulatory surgery centers); and residential/mixed-use projects. We pursue development and investment activity on behalf of our clients on a fee basis with no, or limited, ownership interest in a property, in partnership with our clients through co-investment – either on an individual project basis or through programs with certain strategic capital partners or for our own account with 100% ownership. Development services represent a series of distinct daily services rendered over time. Fees are typically payable monthly over the service term or upon contractual defined events, like project milestones. In addition to development fee revenue, we receive various types of variable consideration which can include, but is not limited to, contingent lease-up bonuses, cost saving incentives, profit sharing on sales and at-risk fees. We assess variable consideration on a contract by contract basis, and when appropriate, recognize revenue based on our assessment of the outcome (using the most likely outcome approach or weighted probability) and historical results, if comparable and representative. We accelerate revenue if it is deemed probable there will not be significant reversal in the future. Accounts Receivable and Allowance for Doubtful Accounts We record accounts receivable for our unconditional rights to consideration arising from our performance under contracts with customers. The carrying value of such receivables, net of the allowance for doubtful accounts, represents their estimated net realizable value. We estimate our allowance for doubtful accounts for specific accounts receivable balances based on historical collection trends, the age of outstanding accounts receivables and existing economic conditions associated with the receivables. Past-due accounts receivable balances are written off when our internal collection efforts have been unsuccessful. As a practical expedient, we do not adjust the promised amount of consideration for the effects of a significant financing component when we expect, at contract inception, that the period between our transfer of a promised service to a customer and when the customer pays for that service will be one year or less. We do not typically include extended payment terms in our contracts with customers. Remaining Performance Obligations Remaining performance obligations represent the aggregate transaction prices for contracts where our performance obligations have not yet been satisfied. As of June 30, 2018, the aggregate amount of transaction price allocated to remaining performance obligations in our property leasing business was not significant. We apply the practical expedient related to remaining performance obligations that are part of a contract that has an original expected duration of one year or less and the practical expedient related to variable consideration from remaining performance obligations pursuant to the series guidance. All of our remaining performance obligations apply to one of these practical expedients. Contract Assets and Contract Liabilities Contract assets represent assets for revenue that has been recognized in advance of billing the customer and for which the right to bill is contingent upon something other than the passage of time. This is common for contingent portions of commissions in brokerage and incentive fees present in various businesses. Billing requirements vary by contract but are generally structured around fixed monthly fees, reimbursement of employee and other third-party costs, and the achievement or completion of certain contingent events. When we receive consideration, or such consideration is unconditionally due, from a customer prior to transferring services to the customer under the terms of the services contract, we record deferred revenue, which represents a contract liability. Such deferred revenue typically results from milestone payments pertaining to future services not yet rendered. We recognize the contract liability as revenue once we have transferred control of service to the customer and all revenue recognition criteria are met. Contract assets and contract liabilities are determined for each contract on a net basis. For contract assets, we classify the short-term portion as a separate line item within current assets and the long-term portion within other assets, long-term in the accompanying consolidated balance sheets. For contract liabilities, we classify the short-term portion as a separate line item within current liabilities and the long-term portion within other liabilities, long-term in the accompanying consolidated balance sheets. Contract Costs Contract costs primarily consist of upfront costs incurred to obtain or to fulfill a contract. These costs are typically found within our Occupier Outsourcing business line. Such costs relate to transition costs to fulfill contracts prior to services being rendered and are included within other intangible assets in the accompanying consolidated balance sheets. Capitalized transition costs are amortized based on the transfer of services to which the assets relate which can vary on a contract by contract basis, and are included in cost of services in the accompanying consolidated statement of operations. For contract costs that are recognized as assets, we periodically review for impairment. Applying the contract cost practical expedient, we recognize the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets that we otherwise would have recognized is one year or less. Income Taxes On December 22, 2017, the Tax Cuts and Jobs Act (Tax Act) was signed into law making significant changes to the Internal Revenue Code, including, but not limited to: (i) a U.S. corporate tax rate decrease from 35% to 21%, effective for tax years beginning after December 31, 2017; (ii) the transition of U.S. international taxation from a worldwide tax system to a territorial system; and (iii) a one-time transition tax (i.e. toll charge) on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017. In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (SAB 118), “ Income Tax Accounting Implications of the Tax Cuts and Jobs Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 Our provision for income taxes for 2017 included a provisional amount related to our estimate of the U.S. federal and state tax impact of the transition tax and other components of the Tax Act. In the first quarter of 2018, we obtained additional information affecting the provisional amount initially recorded for the transition tax. As a result, we recorded an immaterial adjustment to the transition tax in the tax provision for the six months ended June 30, 2018. Provisional amounts that have been recorded are based upon our best estimate of the impact of the Tax Act in accordance with our understanding of the Tax Act and the related guidance available. Additional work is necessary on the provisional amount related to the transition tax, which includes performing a more detailed analysis of historic foreign earnings and tax pools and potential corresponding adjustments. See Note 2 of the Notes to Consolidated Financial Statements set forth in Item 8 included in our Annual Report on Form 10-K for the year ended December 31, 2017 for a summary of our other significant accounting policies.

Accounting Changes And Error Corrections [Abstract]
New Accounting Pronouncements	3. New Accounting Pronouncements Recently Adopted Accounting Pronouncements The FASB previously issued five ASUs related to revenue recognition (“new revenue recognition guidance”). The ASUs issued were: (1) in May 2014, ASU 2014‑09, “Revenue from Contracts with Customers (Topic 606);” n March 2016, ASU 2016‑08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net);” (3) in “ Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing;” (4) in “ Revenue from Contracts with Customers (Topic 606): Narrow-scope Improvements and Practical Expedients;” and (5) in December 2016, ASU 2016‑20, “Technical Corrections and Improvements to Topic 606, Revenue From Contracts with Customers.” We evaluated the impact of the updated principal versus agent guidance on our consolidated financial statements. Under former GAAP, certain third-party costs associated with our facilities and project management contracts were accounted for on a net basis because the contracts include provisions such as “pay when paid” that mitigate payment risk with respect to services provided by third parties to our clients. Under the new revenue recognition guidance, control of the services before transfer to the client is the primary factor in determining principal versus agent assessments. Payment risk is no longer a determining factor under Topic 606. We have determined that we control the services provided by third parties on behalf of certain of our facilities and project management clients. Accordingly, under the new guidance, we are accounting for the cost of services provided by third parties and the related reimbursement revenue on a gross basis. The following table presents the effects of the adoption of the new revenue recognition guidance on our consolidated balance sheet as of December 31, 2017 (dollars in thousands): As Reported Adoption of New Revenue Recognition Guidance As Adjusted Receivables $ 3,207,285 $ (94,996 ) $ 3,112,289 Contract assets — 273,053 273,053 Total current assets 5,452,527 178,057 5,630,584 Other assets, net 422,965 56,509 479,474 Total assets 11,483,830 234,566 11,718,396 Accounts payable and accrued expenses 1,674,287 (100,615 ) 1,573,672 Compensation and employee benefits payable 803,504 100,930 904,434 Accrued bonus and profit sharing 1,072,976 5,369 1,078,345 Contract liabilities — 100,615 100,615 Total current liabilities 4,606,645 106,299 4,712,944 Deferred tax liabilities, net 114,017 33,201 147,218 Total liabilities 7,404,282 139,500 7,543,782 Accumulated earnings 3,348,385 94,622 3,443,007 Accumulated other comprehensive loss (552,858 ) 444 (552,414 ) Total CBRE Group, Inc. stockholders' equity 4,019,430 95,066 4,114,496 Total liabilities and equity 11,483,830 234,566 11,718,396 The following tables present the effects of the adoption of the new revenue recognition guidance on our consolidated statements of operations for the three and six months ended June 30, 2017 (dollars in thousands, except share amounts): Three Months Ended June 30, 2017 As Reported Adoption of New Revenue Recognition Guidance As Adjusted Revenue $ 3,342,215 $ 1,097,356 $ 4,439,571 Cost of services 2,318,562 1,090,978 3,409,540 Operating, administrative and other 712,374 241 712,615 Operating income 222,191 6,137 228,328 Income before provision for income taxes 266,758 6,137 272,895 Provision for income taxes 68,362 1,525 69,887 Net income 198,396 4,612 203,008 Net income attributable to CBRE Group, Inc. 197,165 4,612 201,777 Earnings per share: Basic income per share $ 0.59 $ 0.01 $ 0.60 Diluted income per share 0.58 0.01 0.59 Six Months Ended June 30, 2017 As Reported Adoption of New Revenue Recognition Guidance As Adjusted Revenue $ 6,323,419 $ 2,167,118 $ 8,490,537 Cost of services 4,405,641 2,150,376 6,556,017 Operating, administrative and other 1,318,605 636 1,319,241 Operating income 417,433 16,106 433,539 Income before provision for income taxes 449,534 16,106 465,640 Provision for income taxes 119,635 4,071 123,706 Net income 329,899 12,035 341,934 Net income attributable to CBRE Group, Inc. 326,762 12,035 338,797 Earnings per share: Basic income per share $ 0.97 $ 0.04 $ 1.01 Diluted income per share 0.96 0.04 1.00 See Note 2 for further discussion of the effects of the adoption of ASU 2014-09 on our significant accounting policies. In January 2016, the FASB issued ASU 2016‑01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” In August 2016, the FASB issued ASU 2016‑15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments.” • An accounting policy election was made in the first quarter of 2018 to classify distributions from all of our equity method investments based on the • Purchase price payments made related to acquisitions more than three months after the acquisition closed are to be reflected as cash flows from financing activities (assuming they do not exceed the amount recorded in the initial measurement period). If we record an increase to the estimated purchase price liability post-measurement period, then such increase (i.e. amounts we pay out above and beyond initial estimate of liability) would get recorded as an operating cash flow. This resulted in $15.1 million of cash paid for acquisitions being reclassified from cash used in investing activities to cash used in financing activities for the first six months of 2017; • Payments for debt prepayment or debt extinguishment costs, including third-party costs, premiums paid, and other fees paid to lenders that are directly related to the debt prepayment or debt extinguishment are to be reflected as cash used in financing activities. During the six months ended June 30, 2018, we paid a $20.0 million premium in connection with the early redemption of our 5.00% senior notes (see Note 9). Such premium has been reflected in cash used in financing activities in the consolidated statement of cash flows for the six months ended June 30, 2018. In November 2016, the FASB issued ASU 2016‑18, “Statement of Cash Flows (Topic 230): Restricted Cash.” Recent Accounting Pronouncements Pending Adoption The FASB previously issued two ASUs related to leases. The ASUs issued were: (1) in February 2016, ASU 2016-02, “Leases (Topic 842)” “Codification Improvements to Topic 842, Leases.” In June 2016, the FASB issued ASU 2016‑13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” In January 2017, the FASB issued ASU 2017‑04, “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” In March 2017, the FASB issued ASU 2017‑08, “Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities.” In August 2017, the FASB issued ASU 2017‑12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.” In February 2018, the FASB issued ASU 2018‑02, “Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” In July 2018, the FASB issued ASU 2018‑09, “Codification Improvements.”

FacilitySource Acquisition

Business Combinations [Abstract]
FacilitySource Acquisition	4. FacilitySource Acquisition On June 12, 2018, CBRE Jason Acquisition LLC (Merger Sub), our wholly-owned subsidiary, and FacilitySource Holdings, LLC (FacilitySource), WP X Finance, LP and Warburg Pincus X Partners, LP (collectively, the Stockholders) entered into a stock purchase agreement and plan of merger (the Merger Agreement). As part of the Merger Agreement, (i) we purchased from the Stockholders all the outstanding shares of capital stock of FS WP Holdco, Inc (Blocker Corp), which owned 1,686,013 Class A units (the Blocker Units) and (ii) immediately following the acquisition of Blocker Corp, Merger Sub merged with FacilitySource, with FacilitySource continuing as the surviving company and our wholly-owned subsidiary within our Americas segment (the FacilitySource Acquisition), with the remaining Blocker Units not held by Blocker Corp. cancelled and converted into the right to receive cash consideration as set forth in the Merger Agreement. The estimated net initial purchase price was approximately $265.5 million, with $262.0 million paid in cash, plus adjustments for working capital and other items. We financed the transaction with cash on hand and borrowings under our revolving credit facility. We completed the FacilitySource Acquisition to help us (i) build a tech-enabled supply chain capability that is unique for the occupier outsourcing industry and (ii) drive meaningfully differentiated outcomes for leading occupiers of real estate. The following represents a summary of the excess purchase price over the estimated fair value of net assets acquired (dollars in thousands): Estimated purchase price $ 265,465 Less: Estimated fair value of net assets acquired (see table below) (69,719 ) Excess purchase price over estimated fair value of net assets acquired $ 195,746 The preliminary purchase accounting related to the FacilitySource Acquisition has been recorded in the accompanying consolidated financial statements. The excess purchase price over the estimated fair value of net assets acquired has been recorded to goodwill. The goodwill arising from the FacilitySource Acquisition consists largely of the synergies and economies of scale expected from combining the operations acquired from FacilitySource with ours. We are currently assessing if any portion of the goodwill recorded in connection with the FacilitySource Acquisition will be deductible for tax purposes. Given the complexity of the transaction, the calculation of the fair value of certain assets and liabilities acquired, primarily intangible assets, computer software and income tax items, is still preliminary. The purchase price allocation is expected to be completed as soon as practicable, but no later than one year from the acquisition date. The following table summarizes the aggregate estimated fair values of the assets acquired and the liabilities assumed in the FacilitySource Acquisition (dollars in thousands): Assets Acquired: Cash and cash equivalents $ 2,627 Receivables, net 37,902 Prepaid expenses 477 Property and equipment 60,530 Other intangible assets 89,000 Other assets 114 Total assets acquired 190,650 Liabilities Assumed: Accounts payable and accrued expenses 47,663 Compensation and employee benefits payable 1,800 Accrued bonus and profit sharing 5,036 Line of credit and term loan 26,295 Deferred tax liability 39,009 Other liabilities 1,128 Total liabilities assumed 120,931 Estimated Fair Value of Net Assets Acquired $ 69,719 The following is a summary of the preliminary estimate of the amortizable intangible assets and depreciable computer software acquired in connection with the FacilitySource Acquisition (dollars in thousands): At June 30, 2018 Asset Class Weighted Average Amortization/ Depreciation Period Amount Assigned at Acquisition Date Accumulated Amortization and Depreciation Net Carrying Value Intangibles: Trade names 20 years $ 50,400 $ 105 $ 50,295 Customer relationships 6.67 years 38,600 241 38,359 Total amortizable intangible assets acquired 14.22 years $ 89,000 $ 346 $ 88,654 Property and Equipment: Computer software 10 years $ 57,650 $ 240 $ 57,410 Upon close of the FacilitySource Acquisition, we immediately repaid the line of credit and term loan assumed from FacilitySource. The accompanying consolidated statement of operations for the three and six months ended June 30, 2018 include revenue, an operating loss and a net loss of $12.6 million, ($0.2) million and ($0.2) million, respectively, attributable to the FacilitySource Acquisition. This does not include direct transaction and integration costs of $0.2 million and depreciation and amortization expense of $0.6 million related to computer software and intangible assets acquired, all of which were incurred during both the three and six months ended June 30, 2018 in connection with the FacilitySource Acquisition. Unaudited pro forma results, assuming the FacilitySource Acquisition had occurred as of January 1, 2017 for purposes of the pro forma disclosures for the three and six months ended June 30, 2018 and 2017, are presented below. They include certain adjustments for increased depreciation and amortization expense related to acquired computer software and intangible assets as well as increased interest expense associated with borrowings under our revolving credit facility used to fund the acquisition, as follows (dollars in thousands): Three Months Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 Depreciation expense $ 1,201 $ 1,235 $ 2,642 $ 2,469 Amortization expense 1,731 2,078 3,809 4,155 Interest expense 1,224 1,525 2,748 3,049 Pro forma adjustments also include the removal of $0.2 million of direct costs incurred by us during the three and six months ended June 30, 2018 as well as the tax impact of all pro forma adjustments for all periods presented. These unaudited pro forma results have been prepared for comparative purposes only and do not purport to be indicative of what operating results would have been had the FacilitySource Acquisition occurred on January 1, 2017 and may not be indicative of future operating results (dollars in thousands, except share data): Three Months Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 Revenue $ 5,141,339 $ 4,476,952 $ 9,852,160 $ 8,565,300 Operating income 218,988 220,565 424,689 418,015 Net income attributable to CBRE Group, Inc. 222,941 195,874 366,083 326,993 Basic income per share: Net income per share attributable to CBRE Group, Inc. $ 0.66 $ 0.58 $ 1.08 $ 0.97 Weighted average shares outstanding for basic income per share 339,081,556 336,975,149 338,986,354 336,941,681 Diluted income per share: Net income per share attributable to CBRE Group, Inc. $ 0.65 $ 0.57 $ 1.07 $ 0.96 Weighted average shares outstanding for diluted income per share 343,471,513 340,882,603 343,031,189 340,214,246

Warehouse Receivables And Warehouse Lines Of Credit [Abstract]
Warehouse Receivables & Warehouse Lines of Credit	5. Warehouse Receivables & Warehouse Lines of Credit Our wholly-owned subsidiary CBRE Capital Markets, Inc. (CBRE Capital Markets) is a Federal Home Loan Mortgage Corporation (Freddie Mac) approved Multifamily Program Plus Seller/Servicer and an approved Federal National Mortgage Association (Fannie Mae) Aggregation and Negotiated Transaction Seller/Servicer. In addition, CBRE Capital Markets’ wholly-owned subsidiary CBRE Multifamily Capital, Inc. (CBRE MCI) is an approved Fannie Mae Delegated Underwriting and Servicing (DUS) Seller/Servicer and CBRE Capital Markets’ wholly-owned subsidiary CBRE HMF, Inc. (CBRE HMF) is a U.S. Department of Housing and Urban Development (HUD) approved Non-Supervised Federal Housing Authority (FHA) Title II Mortgagee, an approved Multifamily Accelerated Processing (MAP) lender and an approved Government National Mortgage Association (Ginnie Mae) issuer of mortgage-backed securities (MBS). Under these arrangements, before loans are originated through proceeds from warehouse lines of credit, we obtain either a contractual loan purchase commitment from either Freddie Mac or Fannie Mae or a confirmed forward trade commitment for the issuance and purchase of a Fannie Mae or Ginnie Mae MBS that will be secured by the loans. The warehouse lines of credit are generally repaid within a one-month period when Freddie Mac or Fannie Mae buys the loans or upon settlement of the Fannie Mae or Ginnie Mae MBS, while we retain the servicing rights. Loans are funded at the prevailing market rates. We elect the fair value option for all warehouse receivables. At June 30, 2018 and December 31, 2017, all of the warehouse receivables included in the accompanying consolidated balance sheets were either under commitment to be purchased by Freddie Mac or had confirmed forward trade commitments for the issuance and purchase of Fannie Mae or Ginnie Mae mortgage-backed securities that will be secured by the underlying loans. A rollforward of our warehouse receivables is as follows (dollars in thousands): Beginning balance at December 31, 2017 $ 928,038 Origination of mortgage loans 7,552,229 Gains (premiums on loan sales) 25,890 Proceeds from sale of mortgage loans: Sale of mortgage loans (6,993,724 ) Cash collections of premiums on loan sales (25,890 ) Proceeds from sale of mortgage loans (7,019,614 ) Net increase in mortgage servicing rights included in warehouse receivables 1,781 Ending balance at June 30, 2018 $ 1,488,324 The following table is a summary of our warehouse lines of credit in place as of June 30, 2018 and December 31, 2017 (dollars in thousands): June 30, 2018 December 31, 2017 Maximum Maximum Lender Current Maturity Pricing Facility Size Carrying Value Facility Size Carrying Value JP Morgan Chase Bank, N.A.

Maximum facility reverted back to $400.0 million on February 1, 2018. During July 2018, to accommodate increased volume, line was increased to $800.0 million, which will continue until maturity date unless we elect to adjust. Our arrangement with TD Bank allows us to increase or decrease the line with two-week notice. (2) Line was temporarily increased from $225.0 million to $337.5 million to accommodate year-end volume. Maximum facility reverted back to $225.0 million on January 27, 2018. Effective July 2, 2018, line was temporarily increased from $225.0 million to $337.5 million to accommodate projected volume in July. Maximum facility will revert back to $225.0 million on August 18, 2018. (3) Line was temporarily increased from $200.0 million to $387.5 million to accommodate year-end volume. Maximum facility reverted back to $200.0 million on January 9, 2018. During July 2018, to accommodate increased volume, the line was temporarily increased from $200.0 million to $375.0 million and will revert back to $200.0 million on October 1, 2018. Additionally, in July 2018 the maturity date of the warehouse line with Capital One was extended for one year. During the six months ended June 30, 2018, we had a maximum of $1.5 billion of warehouse lines of credit principal outstanding.

Fair Value Measurements

Fair Value Measurements	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	7. Fair Value Measurements Topic 820 of the FASB Accounting Standards Codification defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Topic 820 also establishes a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: • Level 1 – Quoted prices in active markets for identical assets or liabilities. • Level 2 – Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

FASB ASC Topic 825, “Financial Instruments” • Cash and Cash Equivalents and Restricted Cash – These balances include cash and cash equivalents as well as restricted cash with maturities of less than three months. The carrying amount approximates fair value due to the short-term maturities of these instruments. • Receivables, less Allowance for Doubtful Accounts – Due to their short-term nature, fair value approximates carrying value. • Warehouse Receivables – These balances are carried at fair value based on market prices at the balance sheet date. • Debt & Equity Securities – These investments are carried at their fair value. • Foreign Currency Exchange Forward Contracts – These assets and liabilities are carried at their fair value as calculated by using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. • Securities Sold, not yet Purchased – These liabilities are carried at their fair value. • Short-Term Borrowings – The majority of this balance represents outstanding amounts under our warehouse lines of credit of our wholly-owned subsidiary, CBRE Capital Markets, and our revolving credit facility. Due to the short-term nature and variable interest rates of these instruments, fair value approximates carrying value (see Notes 5 and 9). • Senior Term Loans – Based upon information from third-party banks (which falls within Level 2 of the fair value hierarchy), the estimated fair value of our senior term loans was approximately $742.5 million at June 30, 2018 and $199.9 million at December 31, 2017. Their actual carrying value, net of unamortized debt issuance costs, totaled $743.7 million and $193.5 million at June 30, 2018 and December 31, 2017, respectively (see Note 9). • Interest Rate Swaps – These liabilities are carried at their fair value as calculated by using widely-accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. • Senior Notes – Based on dealers’ quotes (which falls within Level 2 of the fair value hierarchy), the estimated fair values of our 4.875% senior notes and 5.25% senior notes were $622.5 million and $447.0 million, respectively, at June 30, 2018 and $645.7 million and $468.0 million, respectively, at December 31, 2017. The actual carrying value of our 4.875% senior notes and 5.25% senior notes, net of unamortized debt issuance costs as well as unamortized discount or premium, if applicable, totaled $592.4 million and $422.6 million, respectively, at June 30, 2018 and $592.0 million and $422.4 million, respectively, at December 31, 2017. In March 2018, we redeemed our 5.00% senior notes in full (see Note 9). At December 31, 2017, the estimated fair value (based on dealers’ quotes) and actual carrying value (net of unamortized debt issuance costs) of our 5.00% senior notes was $823.8 million and $791.7 million, respectively.

On October 31, 2017, CBRE Services, Inc. (CBRE Services), our wholly-owned subsidiary, entered into a Credit Agreement (the 2017 Credit Agreement), which refinanced and replaced our prior credit agreement (the 2015 Credit Agreement). We used $200.0 million of borrowings from the tranche A term loan facility and $83.0 million of revolving credit facility borrowings under the 2017 Credit Agreement, in addition to cash on hand, to repay all amounts outstanding under the 2015 Credit Agreement. The 2017 Credit Agreement is a senior unsecured credit facility that is jointly and severally guaranteed by us and certain of our subsidiaries. As of June 30, 2018, the 2017 Credit Agreement provided for the following: (1) a $2.8 billion revolving credit facility, which includes the capacity to obtain letters of credit and swingline loans and matures on October 31, 2022 and (2) a $750.0 million delayed draw tranche A term loan facility, requiring quarterly principal payments, which began on March 5, 2018 and continue through maturity on October 31, 2022, provided that in the event that our leverage ratio (as defined in the 2017 Credit Agreement) is less than or equal to 2.50 to 1.00 on the last day of the fiscal quarter immediately preceding any such payment date, no such quarterly principal payment shall be required on such date. On March 14, 2013, CBRE Services issued $800.0 million in aggregate principal amount of 5.00% senior notes due March 15, 2023. The 5.00% senior notes were unsecured obligations of CBRE Services, senior to all of its current and future subordinated indebtedness, but effectively subordinated to all of its current and future secured indebtedness. The 5.00% senior notes were jointly and severally guaranteed on a senior basis by us and each domestic subsidiary of CBRE Services that guaranteed our 2017 Credit Agreement. Interest accrued at a rate of 5.00% per year and was payable semi-annually in arrears on March 15 and September 15. The 5.00% senior notes were redeemable at our option, in whole or in part, on March 15, 2018 at a redemption price of 102.5% of the principal amount on that date. We redeemed these notes in full on March 15, 2018 and incurred charges of $28.0 million, including a premium of $20.0 million and the write-off of $8.0 million of unamortized deferred financing costs. We funded this redemption with $550.0 million of borrowings from our tranche A term loan facility and borrowings from our revolving credit facility under our 2017 Credit Agreement. The amount of the 5.00% senior notes, net of unamortized debt issuance costs, included in the accompanying consolidated balance sheets was $791.7 million at December 31, 2017. The indentures governing our 4.875% senior notes and 5.25% senior notes contain restrictive covenants that, among other things, limit our ability to create or permit liens on assets securing indebtedness, enter into sale/leaseback transactions and enter into consolidations or mergers. In addition, our 2017 Credit Agreement also requires us to maintain a minimum coverage ratio of consolidated EBITDA (as defined in the 2017 Credit Agreement) to consolidated interest expense of 2.00x and a maximum leverage ratio of total debt less available cash to consolidated EBITDA (as defined in the 2017 Credit Agreement) of 4.25x (and in the case of the first four full fiscal quarters following consummation of a qualified acquisition (as defined in the 2017 Credit Agreement), 4.75x) as of the end of each fiscal quarter. On this basis, our coverage ratio of consolidated EBITDA to consolidated interest expense was 16.97x for the trailing twelve months ended June 30, 2018, and our leverage ratio of total debt less available cash to consolidated EBITDA was 1.05x as of June 30, 2018. Short-Term Borrowings Revolving Credit Facility As of June 30, 2018, letters of credit totaling $2.0 million were outstanding under our revolving credit facility under our 2017 Credit Agreement. These letters of credit, which reduce the amount we may borrow under the revolving credit facility, were primarily issued in the ordinary course of business. As of June 30, 2018, $598.0 million was outstanding under the revolving credit facility. As of December 31, 2017, no amounts were outstanding under the revolving credit facility other than letters of credit totaling $2.0 million. Warehouse Lines of Credit CBRE Capital Markets has warehouse lines of credit with third-party lenders for the purpose of funding mortgage loans that will be resold, and a funding arrangement with Fannie Mae for the purpose of selling a percentage of certain closed multifamily loans to Fannie Mae. These warehouse lines are recourse only to CBRE Capital Markets and are secured by our related warehouse receivables. See Note 5 for additional information.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	10. Commitments and Contingencies We are a party to a number of pending or threatened lawsuits arising out of, or incident to, our ordinary course of business. We believe that any losses in excess of the amounts accrued therefor as liabilities on our financial statements are unlikely to be significant, but litigation is inherently uncertain and there is the potential for a material adverse effect on our financial statements if one or more matters are resolved in a particular period in an amount materially in excess of what we anticipated. In January 2008, CBRE MCI, a wholly-owned subsidiary of CBRE Capital Markets, entered into an agreement with Fannie Mae under Fannie Mae’s Delegated Underwriting and Servicing Lender Program (DUS Program), to provide financing for multifamily housing with five or more units. Under the DUS Program, CBRE MCI originates, underwrites, closes and services loans without prior approval by Fannie Mae, and typically, is subject to sharing up to one-third of any losses on loans originated under the DUS Program. CBRE MCI has funded loans subject to such loss sharing arrangements with unpaid principal balances of $21.3 billion at June 30, 2018. CBRE MCI, under its agreement with Fannie Mae, must post cash reserves or other acceptable collateral under formulas established by Fannie Mae to provide for sufficient capital in the event losses occur. As of June 30, 2018 and December 31, 2017, CBRE MCI had a $60.0 million and a $58.0 million, respectively, letter of credit under this reserve arrangement, and had recorded a liability of approximately $33.9 million and $32.9 million, respectively, for its loan loss guarantee obligation under such arrangement. Fannie Mae’s recourse under the DUS Program is limited to the assets of CBRE MCI, which assets totaled approximately $734.0 million (including $491.1 million of warehouse receivables, a substantial majority of which are pledged against warehouse lines of credit and are therefore not available to Fannie Mae) at June 30, 2018. CBRE Capital Markets participates in Freddie Mac’s Multifamily Small Balance Loan (SBL) Program. Under the SBL program, CBRE Capital Markets has certain repurchase and loss reimbursement obligations. These obligations are for the period from origination of the loan to the securitization date. CBRE Capital Markets must post a cash reserve or other acceptable collateral to provide for sufficient capital in the event the obligations are triggered. As of June 30, 2018 and December 31, 2017, CBRE Capital Markets had posted a $5.0 million letter of credit under this reserve arrangement. We had outstanding letters of credit totaling $71.2 We had guarantees totaling $56.3 million as of June 30, 2018, excluding guarantees related to pension liabilities, consolidated indebtedness and other obligations for which we have outstanding liabilities already accrued on our consolidated balance sheet, and excluding guarantees related to operating leases. The $56.3 million primarily represents guarantees executed by us in the ordinary course of business, including various guarantees of management and vendor contracts in our operations overseas, which expire at the end of each of the respective agreements. In addition, as of June 30, 2018, we had issued numerous non-recourse carveout, completion and budget guarantees relating to development projects for the benefit of third parties. These guarantees are commonplace in our industry and are made by us in the ordinary course of our Development Services business. Non-recourse carveout guarantees generally require that our project-entity borrower not commit specified improper acts, with us potentially liable for all or a portion of such entity’s indebtedness or other damages suffered by the lender if those acts occur. Completion and budget guarantees generally require us to complete construction of the relevant project within a specified timeframe and/or within a specified budget, with us potentially being liable for costs to complete in excess of such timeframe or budget. However, we generally use “guaranteed maximum price” contracts with reputable, bondable general contractors with respect to projects for which we provide these guarantees. These contracts are intended to pass the risk to such contractors. While there can be no assurance, we do not expect to incur any material losses under these guarantees. An important part of the strategy for our Global Investment Management business involves investing our capital in certain real estate investments with our clients. These co-investments generally total up to 2.0% of the equity in a particular fund. As of June 30, 2018, we had aggregate commitments of $36.5 million to fund future co-investments. Additionally, an important part of our Development Services business strategy is to invest in unconsolidated real estate subsidiaries as a principal (in most cases co-investing with our clients). As of June 30, 2018, we had committed to fund $23.5 million of additional capital to these unconsolidated subsidiaries.

During the six months ended June 30, 2018, our contract assets decreased by $161.7 million, primarily due to contract assets moving to accounts receivable in our occupier outsourcing business (due to at-risk and incentive fees becoming billable per the contract terms) and in our leasing business (billing of commissions). We had contract liabilities totaling $86.8 million ($76.2 million of which was current) and $100.6 million (all of which was current) as of June 30, 2018 and December 31, 2017, respectively. During the six months ended June 30, 2018, we recognized revenue of $64.1 million that was included in the contract liability balance at December 31, 2017. Contract Costs Within our Occupier Outsourcing business line, we incur transition costs to fulfil contracts prior to services being rendered. We capitalized $13.4 million and $23.0 million, respectively, of transition costs during the three and six months ended June 30, 2018, and $5.8 million and $14.7 million, respectively, of transition costs during the three and six months ended June 30, 2017. We recorded amortization of transition costs of $6.2 million and $12.2 million, respectively, during the three and six months ended June 30, 2018 and $3.6 million and $7.2 million, respectively, during the three and six months ended June 30, 2017. No impairment loss in relation to the costs capitalized was recorded during the three and six months ended June 30, 2018 or 2017.

Subsequent Events [Abstract]
Subsequent Event	15. Subsequent Event I n June 2016, CBRE was named as a defendant in a class action lawsuit relating to its role as property manager of certain real estate investment properties owned by the plaintiffs in Florida. CBRE started managing these various properties between July 2005 and March 2007, and CBRE ceased managing these properties in January 2011. The third-party sponsors of such investment properties inappropriately managed funds for the plaintiffs which resulted in losses, used some of these funds for personal purposes, and were imprisoned for their conduct. Since the third-party sponsors could not answer financially for the resulting losses to the plaintiffs, the plaintiffs made claims against CBRE generally alleging that CBRE should have prevented the fraud perpetuated by the third-party sponsors with respect to the properties managed by CBRE. On August 3, 2018, we reached a tentative settlement agreement regarding this proceeding, which agreement is subject to negotiation of definitive settlement documentation and court approval, including the payment of $100 million to the plaintiffs. We expect that such settlement payment will be funded principally by insurance coverage

Accounting Policies [Abstract]
New Accounting Pronouncements	Revenue Recognition We account for revenue in accordance with Accounting Standards Codification (ASC) Topic 606, “ Revenue from Contracts with Customers Other Assets and Deferred Costs – Contracts with Customers The following is a description of principal activities – separated by reportable segments – from which we generate revenue. For more detailed information about our reportable segments, see Notes 12 and 13. The Americas, Europe, Middle East and Africa (EMEA), and Asia Pacific The Americas segment is our largest segment of operations and provides a comprehensive range of services throughout the United States (U.S.), in the largest regions of Canada and in key markets in Latin America. The primary services offered consist of the following: property leasing, property sales, mortgage services, appraisal and valuation, occupier outsourcing and property management services. Our EMEA and Asia Pacific segments generally provide services similar to the Americas business segment. The EMEA segment has operations primarily in Europe, while the Asia Pacific segment has operations in Asia, Australia and New Zealand. Property Leasing and Property Sales Through our Advisory & Transaction Services business line, we provide strategic advice and execution to owners, investors, and occupiers of real estate in connection with the leasing of office, industrial and retail space. We also offer clients fully integrated property sales services under the CBRE Capital Markets brand. We are compensated for our services in the form of a commission and, in some instances may earn various forms of variable incentive consideration. Our commission is paid upon the occurrence of certain contractual event(s) which may be contingent. For example, a portion of our leasing commission may be paid upon signing of the lease by the tenant, with the remaining paid upon occurrence of another future contingent event (e.g. payment of first month’s rent or tenant move-in). For sales, our commission is typically paid at the closing of the sale. We typically satisfy our performance obligation at a point in time when control is transferred; generally, at the time of the first contractual event where there is a present right to payment. We look to history, experience with a customer, and deal specific considerations to support our judgement that the second contingency (if applicable) will be met. Therefore, we typically accelerate the recognition of the revenue associated with the second contingent event. In addition to our commission, we may recognize other forms of variable consideration which can include, but are not limited to, commissions subject to concession or claw back and volume based discounts or rebates. We assess variable consideration on a contract by contract basis, and when appropriate, recognize revenue based on our assessment of the outcome (using the most likely outcome approach or weighted probability) and historical results, if comparable and representative. We recognize variable consideration if it is deemed probable that there will not be significant reversal in the future. Mortgage Originations and Loan Sales Under the CBRE Capital Markets brand, we offer clients fully integrated commercial mortgage and structured financing services. Fees from services within our mortgage brokerage business that are in the scope of Topic 606 include fees earned for the brokering of commercial mortgage loans primarily through relationships established with investment banking firms, national and regional banks, credit companies, insurance companies and pension funds. We are compensated for our brokerage services via a fee paid upon successful placement of a commercial mortgage borrower with a lender who will provide financing. The fee earned is contingent upon the funding of the loan. We typically satisfy our performance obligation when control is transferred at the point in time of the funding of the loan. We also earn fees from the origination and sale of commercial mortgage loans for which the company retains the servicing rights. These fees are governed by the “ Fair Value Measurements and Disclosures Transfers and Servicing Appraisal and Valuation We provide valuation services that include market-value appraisals, litigation support, discounted cash flow analyses, feasibility studies as well as consulting services such as property condition reports, hotel advisory and environmental consulting. We are compensated for valuation services in the form of a fee, which is payable on the occurrence of certain events (e.g., a portion on the delivery of a draft report with the remaining on the delivery of the final report). For consulting services, we may be paid based on the occurrence of time or event-based milestones (such as the delivery of draft reports). We typically satisfy our performance obligation as services are rendered over time. Occupier Outsourcing Services We provide a broad suite of services to occupiers of real estate, including facilities management, project management, transaction management and strategic consulting. We report facilities and project management as well as strategic consulting activities in our occupier outsourcing revenue line and transaction management in our lease and sales revenue lines. Facilities management involves the day-to-day management of client-occupied space and includes headquarter buildings, regional offices, administrative offices, data centers and other critical facilities, manufacturing and laboratory facilities, distribution facilities and retail space. Contracts for facilities management services are often structured so we are reimbursed for client-dedicated personnel costs and subcontracted vendor costs as well as associated overhead expenses plus a monthly fee, and, in some cases, annual incentives tied to agreed-upon performance targets, with any penalties typically capped. Facilities management services represent a series of distinct daily services rendered over time. Project management services are often provided on a portfolio wide or programmatic basis. Revenues from project management services generally includes fixed management fees, variable fees, and incentive fees if certain agreed-upon performance targets are met. Revenues from project management may also include reimbursement of payroll and related costs for personnel providing the services and subcontracted vendor costs. Project management services represent a series of distinct daily services rendered over time. The amount of revenue recognized is presented gross for any services provided by our employees, as we control them. This is evidenced by our obligation for their performance and our ability to direct and redirect their work, as well as negotiate the value of such services. The amount of revenue recognized related to the majority of facilities management contracts and certain project management arrangements is presented gross (with offsetting expense recorded in cost of services) for reimbursements of costs of third-party services because we control those services that are delivered to the client. In the instances when we do not control third-party services delivered to the client, we report revenues net of the third-party reimbursements. In addition to our management fee, we receive various types of variable consideration which can include, but is not limited to; key performance indicator bonuses or penalties which may be linked to subcontractor performance, gross maximum price, glidepaths, savings guarantees, shared savings, or fixed fee structures. We assess variable consideration on a contract by contract basis, and when appropriate, recognize revenue based on our assessment of the outcome (using the most likely outcome approach or weighted probability) and historical results, if comparable and representative. Using management assessment and historical results and statistics, we accelerate revenue if it is deemed probable there will not be significant reversal in the future. Property Management We provide property management services on a contractual basis for owners of and investors in office, industrial and retail properties. These services include construction management, marketing, building engineering, accounting and financial services. We are compensated for our services through a monthly management fee earned based on either a specified percentage of the monthly rental income, rental receipts generated from the property under management or a fixed fee. We are also often reimbursed for our administrative and payroll costs directly attributable to the properties under management. Property management services represent a series of distinct daily services rendered over time. The amount of revenue recognized is presented gross for any services provided by our employees, as we control them. We generally do not control third-party services delivered to property management clients. As such, we report revenues net of third-party reimbursements. Global Investment Management Our Global Investment Management business segment provides investment management services to pension funds, insurance companies, sovereign wealth funds, foundations, endowments and other institutional investors seeking to generate returns and diversification through investment in real estate. We sponsor investment programs that span the risk/return spectrum in: North America, Europe, Asia and Australia. We are typically compensated in the form of a base management fee, disposition fees, acquisition fees and incentive fees in the form of performance fees or carried interest based on fund type (open or closed ended, respectively). For the base management fee, we typically satisfy the performance obligation as service is rendered over time pursuant to the series guidance. For acquisition and disposition services, we typically satisfy the performance obligation at a point in time (at acquisition or upon disposition). For contracts with contingent fees, including performance fees, incentive fees and carried interest, we assess variable consideration on a contract by contract basis, and when appropriate, recognize revenue based on our assessment of the outcome (using the most likely outcome approach or weighted probability) and historical results, if comparable and representative. Revenue associated with performance fees and carried interest are typically constrained due to volatility in the real estate market, a broad range of possible outcomes, and other factors in the market that are outside of our control. Development Services Our Development Services business segment consists of real estate development and investment activities primarily in the United States to users of and investors in commercial real estate, as well as for our own account. We pursue opportunistic, risk-mitigated development and investment in commercial real estate across a wide spectrum of property types, including: industrial, office and retail properties; healthcare facilities of all types (medical office buildings, hospitals and ambulatory surgery centers); and residential/mixed-use projects. We pursue development and investment activity on behalf of our clients on a fee basis with no, or limited, ownership interest in a property, in partnership with our clients through co-investment – either on an individual project basis or through programs with certain strategic capital partners or for our own account with 100% ownership. Development services represent a series of distinct daily services rendered over time. Fees are typically payable monthly over the service term or upon contractual defined events, like project milestones. In addition to development fee revenue, we receive various types of variable consideration which can include, but is not limited to, contingent lease-up bonuses, cost saving incentives, profit sharing on sales and at-risk fees. We assess variable consideration on a contract by contract basis, and when appropriate, recognize revenue based on our assessment of the outcome (using the most likely outcome approach or weighted probability) and historical results, if comparable and representative. We accelerate revenue if it is deemed probable there will not be significant reversal in the future. Accounts Receivable and Allowance for Doubtful Accounts We record accounts receivable for our unconditional rights to consideration arising from our performance under contracts with customers. The carrying value of such receivables, net of the allowance for doubtful accounts, represents their estimated net realizable value. We estimate our allowance for doubtful accounts for specific accounts receivable balances based on historical collection trends, the age of outstanding accounts receivables and existing economic conditions associated with the receivables. Past-due accounts receivable balances are written off when our internal collection efforts have been unsuccessful. As a practical expedient, we do not adjust the promised amount of consideration for the effects of a significant financing component when we expect, at contract inception, that the period between our transfer of a promised service to a customer and when the customer pays for that service will be one year or less. We do not typically include extended payment terms in our contracts with customers. Remaining Performance Obligations Remaining performance obligations represent the aggregate transaction prices for contracts where our performance obligations have not yet been satisfied. As of June 30, 2018, the aggregate amount of transaction price allocated to remaining performance obligations in our property leasing business was not significant. We apply the practical expedient related to remaining performance obligations that are part of a contract that has an original expected duration of one year or less and the practical expedient related to variable consideration from remaining performance obligations pursuant to the series guidance. All of our remaining performance obligations apply to one of these practical expedients. Contract Assets and Contract Liabilities Contract assets represent assets for revenue that has been recognized in advance of billing the customer and for which the right to bill is contingent upon something other than the passage of time. This is common for contingent portions of commissions in brokerage and incentive fees present in various businesses. Billing requirements vary by contract but are generally structured around fixed monthly fees, reimbursement of employee and other third-party costs, and the achievement or completion of certain contingent events. When we receive consideration, or such consideration is unconditionally due, from a customer prior to transferring services to the customer under the terms of the services contract, we record deferred revenue, which represents a contract liability. Such deferred revenue typically results from milestone payments pertaining to future services not yet rendered. We recognize the contract liability as revenue once we have transferred control of service to the customer and all revenue recognition criteria are met. Contract assets and contract liabilities are determined for each contract on a net basis. For contract assets, we classify the short-term portion as a separate line item within current assets and the long-term portion within other assets, long-term in the accompanying consolidated balance sheets. For contract liabilities, we classify the short-term portion as a separate line item within current liabilities and the long-term portion within other liabilities, long-term in the accompanying consolidated balance sheets. Contract Costs Contract costs primarily consist of upfront costs incurred to obtain or to fulfill a contract. These costs are typically found within our Occupier Outsourcing business line. Such costs relate to transition costs to fulfill contracts prior to services being rendered and are included within other intangible assets in the accompanying consolidated balance sheets. Capitalized transition costs are amortized based on the transfer of services to which the assets relate which can vary on a contract by contract basis, and are included in cost of services in the accompanying consolidated statement of operations. For contract costs that are recognized as assets, we periodically review for impairment. Applying the contract cost practical expedient, we recognize the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets that we otherwise would have recognized is one year or less. Income Taxes On December 22, 2017, the Tax Cuts and Jobs Act (Tax Act) was signed into law making significant changes to the Internal Revenue Code, including, but not limited to: (i) a U.S. corporate tax rate decrease from 35% to 21%, effective for tax years beginning after December 31, 2017; (ii) the transition of U.S. international taxation from a worldwide tax system to a territorial system; and (iii) a one-time transition tax (i.e. toll charge) on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017. In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (SAB 118), “ Income Tax Accounting Implications of the Tax Cuts and Jobs Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 Our provision for income taxes for 2017 included a provisional amount related to our estimate of the U.S. federal and state tax impact of the transition tax and other components of the Tax Act. In the first quarter of 2018, we obtained additional information affecting the provisional amount initially recorded for the transition tax. As a result, we recorded an immaterial adjustment to the transition tax in the tax provision for the six months ended June 30, 2018. Provisional amounts that have been recorded are based upon our best estimate of the impact of the Tax Act in accordance with our understanding of the Tax Act and the related guidance available. Additional work is necessary on the provisional amount related to the transition tax, which includes performing a more detailed analysis of historic foreign earnings and tax pools and potential corresponding adjustments.
