Accounting Policies [Abstract]
Basis of Presentation	1. Basis of Presentation
	The accompanying 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”), 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 (GAAP) for annual financial statements. In the opinion of management, 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 management 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, 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 management’s best judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including consideration of the current economic environment, and adjusts 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 reclassifications have been made to the 2014 financial statements to conform with the 2015 presentation.
	The results of operations for the three months ended March 31, 2015 are not necessarily indicative of the results of operations to be expected for the year ending December 31, 2015. The unaudited interim consolidated financial statements and notes to consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2014, which contains the latest available audited consolidated financial statements and notes thereto, which are as of and for the year ended December 31, 2014.

Accounting Changes and Error Corrections [Abstract]
New Accounting Pronouncements	2. New Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, “Revenue from Contracts with Customers (Topic 606).” This ASU requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance under accounting principles generally accepted in the United States, or GAAP, when it becomes effective on January 1, 2017. This ASU permits the use of either the retrospective or cumulative effect transition method. Early adoption is not permitted. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of this ASU on our ongoing financial reporting.
	In February 2015, the FASB issued ASU 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis.” This ASU provides consolidation guidance for legal entities such as limited partnerships, limited liability corporations and securitization structures. ASU 2015-02 offers updated consolidation evaluation criteria and may require additional disclosures. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, with early adoption permitted. We do not believe the adoption of ASU 2015-02 will have a material impact on our consolidated financial position, results of operations or disclosure requirements of our consolidated financial statements.
	In April 2015, the FASB issued ASU 2015-03, “Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” This ASU requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts, and requires the use of the retrospective method. ASU 2015-03 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, with early adoption permitted. We do not believe the adoption of this ASU will have a material impact on our consolidated financial position.

Variable Interest Entities (VIEs)	3 Months Ended

Equity Method Investments and Joint Ventures [Abstract]
Variable Interest Entities (VIEs)	3. Variable Interest Entities (VIEs)
	A consolidated subsidiary (the Venture) in our Global Investment Management segment sponsored investments by third-party investors in certain commercial properties through the formation of tenant-in-common limited liability companies and Delaware Statutory Trusts (collectively referred to as the Entities) that were owned by the third-party investors. The Venture also formed and was a member of a limited liability company for each property that served as master tenant (Master Tenant). Each Master Tenant leased the property from the Entities through a master lease agreement. Pursuant to the master lease agreements, the Master Tenant had the power to direct the day-to-day asset management activities that most significantly impacted the economic performance of the Entities. As a result, the Entities were deemed to be VIEs since the third-party investors holding the equity investment at risk in the Entities did not direct the day-to-day activities that most significantly impacted the economic performance of the properties held by the Entities. The Venture made voluntary contributions to each of these properties to support their operations beyond the cash flow generated by the properties themselves and such financial support was significant enough that the Venture was deemed to be the primary beneficiary of each Entity. During 2014, the remaining two commercial properties were sold.
	No financial support was provided by the Venture to the Entities during the three months ended March 31, 2014. The assets of the Entities were the sole collateral for the mortgage notes payable and other liabilities of the Entities and, as such, the creditors and equity investors of these Entities had no recourse to our assets held outside of these Entities.
	Operating results relating to the Entities for the three months ended March 31, 2014 included the following (dollars in thousands):
	Revenue	$	2,102
	Operating, administrative and other expenses	$	1,233
	Net income attributable to non-controlling interests	$	478
	We also hold variable interests in certain VIEs in our Global Investment Management and Development Services segments which are not consolidated as it was determined that we are not the primary beneficiary. Our involvement with these entities is in the form of equity co-investments and fee arrangements.
	As of March 31, 2015 and December 31, 2014, our maximum exposure to loss related to the VIEs which are not consolidated was as follows (dollars in thousands):
		March 31,		December 31,
		2015		2014
	Investments in unconsolidated subsidiaries	$	22,863	$	26,353
	Other assets, current		3,427		3,337
	Co-investment commitments		200		200
	Maximum exposure to loss	$	26,490	$	29,890

Fair Value Measurements	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	4. Fair Value Measurements
	The “Fair Value Measurements and Disclosures” Topic of the FASB Accounting Standards Codification (ASC) (Topic 820) 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.
	There were no significant transfers in or out of Level 1 and Level 2 during the three months ended March 31, 2015 and 2014.
	There have been no significant changes to the valuation techniques and inputs used to develop the recurring fair value measurements from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2014. The following tables present the fair value of assets and liabilities measured at fair value on a recurring basis as of March 31, 2015 and December 31, 2014 (dollars in thousands):

	FASB ASC Topic 825, “Financial Instruments” requires disclosure of fair value information about financial instruments, whether or not recognized in the accompanying consolidated balance sheets. Our financial instruments are as follows:
	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.
Trading and Available for Sale Securities: These investments are carried at their fair value.
Foreign Currency Exchange Forward Contracts and Loan Commitments: 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 (see Note 5).
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 for CBRE Capital Markets, Inc. (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.
Senior Secured 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 secured term loans was approximately $500.0 million and $645.1 million at March 31, 2015 and December 31, 2014, respectively. Their actual carrying value totaled $500.0 million and $645.6 million at March 31, 2015 and December 31, 2014, respectively (see Note 10).
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 (see Note 5).
5.00% Senior Notes: Based on dealers’ quotes (which falls within Level 2 of the fair value hierarchy), the estimated fair value of our 5.00% senior notes was $832.0 million and $818.0 million at March 31, 2015 and December 31, 2014, respectively. Their actual carrying value totaled $800.0 million at both March 31, 2015 and December 31, 2014.
5.25% Senior Notes: Based on dealers’ quotes (which falls within Level 2 of the fair value hierarchy), the estimated fair value of our 5.25% senior notes was $457.9 million and $439.7 million at March 31, 2015 and December 31, 2014, respectively. Their actual carrying value totaled $426.8 million at both March 31, 2015 and December 31, 2014.
Notes Payable on Real Estate: As of March 31, 2015 and December 31, 2014, the carrying value of our notes payable on real estate was $43.2 million and $42.8 million, respectively (see Note 9). These borrowings generally have floating interest rates at spreads added to a market rate index. It is likely that some portion of our notes payable on real estate have fair values lower than actual carrying values. Given the cost involved in estimating their fair value, we determined it was not practicable to do so. Additionally, these notes payable were not recourse to us as of March 31, 2015 or December 31, 2014.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	5. Derivative Financial Instruments
	We are exposed to certain risks arising from both our business operations and economic conditions. We manage economic risks, including interest rate, liquidity and credit risk primarily by managing the amount, sources and duration of our debt funding and by using derivative financial instruments. Specifically, we enter into derivative financial instruments to manage exposures that arise from business activities that result in the payment of future known but uncertain cash amounts, the value of which are determined by interest rates. Our derivative financial instruments are used to manage differences in the amount, timing, and duration of our known or expected cash payments principally related to our borrowings. We do not net derivatives on our balance sheet. Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposure to interest rate movements. To accomplish this objective, we primarily use interest rate swaps as part of our interest rate risk management strategy.
	In March 2011, we entered into five interest rate swap agreements, all with effective dates in October 2011, and immediately designated them as cash flow hedges in accordance with FASB ASC Topic 815, “Derivatives and Hedging.” The purpose of these interest rate swap agreements is to attempt to hedge potential changes to our cash flows due to the variable interest nature of our senior secured term loan facilities. The total notional amount of these interest rate swap agreements is $400.0 million, with $200.0 million expiring in October 2017 and $200.0 million expiring in September 2019. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. There was no significant hedge ineffectiveness for the three months ended March 31, 2015 and 2014. The effective portion of changes in the fair value of derivatives designated and qualifying as cash flow hedges is recorded in accumulated other comprehensive loss on the balance sheet and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. We reclassified $2.9 million and $3.0 million for the three months ended March 31, 2015 and 2014, respectively, from accumulated other comprehensive loss to interest expense. During the next twelve months, we estimate that $11.2 million will be reclassified from accumulated other comprehensive loss to interest expense. In addition, we recorded net losses of $4.5 million and $2.6 million for the three months ended March 31, 2015 and 2014, respectively, to other comprehensive income/loss in relation to such interest rate swap agreements. As of March 31, 2015 and December 31, 2014, the fair values of such interest rate swap agreements were reflected as a $28.5 million liability and a $26.9 million liability, respectively, and were included in other long-term liabilities in the accompanying consolidated balance sheets.
	Additionally, our foreign operations expose us to fluctuations in foreign exchange rates. These fluctuations may impact the value of our cash receipts and payments in terms of our functional currency. We enter into derivative financial instruments to attempt to protect the value or fix the amount of certain obligations in terms of our reporting currency, the U.S. dollar. In March 2014, we began a foreign currency exchange forward hedging program by entering into 38 foreign currency exchange forward contracts, including agreements to buy U.S. dollars and sell Australian dollars, Canadian dollars, Japanese yen, Euros and British pound sterling covering an initial notional amount of $209.7 million. The purpose of these forward contracts is to attempt to mitigate the risk of fluctuations in foreign currency exchange rates that would adversely impact some of our foreign currency denominated EBITDA. Hedge accounting was not elected for any of these contracts. As such, changes in the fair values of these contracts are recorded directly in earnings. Included in the consolidated statement of operations were net gains of $18.4 million from foreign currency exchange forward contracts for the three months ended March 31, 2015. The net impact on earnings resulting from gains and/or losses associated with these contracts during the three months ended March 31, 2014 was not significant. As of March 31, 2015, we had 44 foreign currency exchange forward contracts outstanding covering a notional amount of $257.5 million. As of March 31, 2015, the fair value of forward contracts with four counterparties aggregated to a $16.6 million asset position, which was included in other current assets in the accompanying consolidated balance sheets. As of March 31, 2015, the fair value of forward contracts with one counterparty aggregated to a $0.1 million liability position, which was included in other current liabilities in the accompanying consolidated balance sheets. As of December 31, 2014, the fair value of forward contracts with two counterparties aggregated to a $0.5 million asset position, which was included in other current assets in the accompanying consolidated balance sheets. As of December 31, 2014, the fair value of forward contracts with four counterparties aggregated to a $1.3 million liability position, which was included in other current liabilities in the accompanying consolidated balance sheets.
	We also routinely monitor our exposure to currency exchange rate changes in connection with certain transactions and sometimes enter into foreign currency exchange option and forward contracts to limit our exposure to such transactions, as appropriate. In the ordinary course of business, we also sometimes utilize derivative financial instruments in the form of foreign currency exchange contracts to attempt to mitigate foreign currency exchange exposure resulting from intercompany loans. Included in the consolidated statements of operations were net gains of $0.4 million for the three months ended March 31, 2015 resulting from net gains on these foreign currency exchange option and forward contracts. The net impact on earnings resulting from gains and/or losses associated with these contracts during the three months ended March 31, 2014 was not significant. As of March 31, 2015, we had four foreign currency exchange option and forward contracts outstanding covering a notional amount of $35.9 million. As of March 31, 2015, the fair value of forward contracts with one counterparty aggregated to a $1.2 million asset position, which was included in other current assets in the accompanying consolidated balance sheets. As of March 31, 2015, the fair value of forward contracts with one counterparty aggregated to a $0.2 million liability position, which was included in other current liabilities in the accompanying consolidated balance sheets. As of December 31, 2014, the fair value of forward contracts with one counterparty aggregated to a $0.8 million asset position, which was included in other current assets in the accompanying consolidated balance sheets. As of December 31, 2014, the fair value of forward contracts with one counterparty aggregated to a $0.1 million liability position, which was included in other current liabilities in the accompanying consolidated balance sheets.
	We also enter into loan commitments that relate to the origination of commercial mortgage loans that will be held for resale. FASB ASC Topic 815 requires that these commitments be recorded at their fair values as derivatives. Included in the consolidated statements of operations were net gains of $4.0 million for the three months ended March 31, 2015, resulting from gains on these loan commitments. The net impact on earnings resulting from gains and/or losses associated with these loan commitments during the three months ended March 31, 2014 was not significant. As of March 31, 2015, the fair value of such contracts with three counterparties aggregated to a $4.0 million asset position, which was included in other current assets in the accompanying consolidated balance sheets. As of December 31, 2014, the fair value of such contracts with three counterparties aggregated to a $2.4 million asset position, which was included in other current assets in the accompanying consolidated balance sheets.

Debt Disclosure [Abstract]
Debt	10. Debt
	Since 2001, we have maintained credit facilities to fund strategic acquisitions and to provide for our working capital needs. On March 28, 2013, we entered into a credit agreement (the 2013 Credit Agreement) with a syndicate of banks led by Credit Suisse Group AG (CS) as administrative and collateral agent, to completely refinance a previous credit agreement. On January 9, 2015, we entered into an amended and restated credit agreement (the 2015 Credit Agreement) with a syndicate of banks jointly led by Merrill Lynch, Pierce, Fenner & Smith Incorporated, J.P. Morgan Securities LLC and CS. In January 2015, we used the proceeds from the tranche A term loan facility under the 2015 Credit Agreement and from the December 2014 issuance of $125.0 million of 5.25% senior notes due 2025, along with cash on hand, to pay off the prior tranche A and tranche B term loans and the previously outstanding balance on our revolving credit facility under the 2013 Credit Agreement.
	As of March 31, 2015, our 2015 Credit Agreement provides for the following: (1) a $2.6 billion revolving credit facility, which includes the capacity to obtain letters of credit and swingline loans and matures on January 9, 2020; and (2) a $500.0 million tranche A term loan facility requiring quarterly principal payments, which begin on June 30, 2015 and continue through maturity on January 9, 2020.
	The revolving credit facility under the 2015 Credit Agreement allows for borrowings outside of the United States (U.S.), with a $75.0 million sub-facility available to one of our Canadian subsidiaries, a $100.0 million sub-facility available to one of our Australian subsidiaries and one of our New Zealand subsidiaries and a $300.0 million sub-facility available to one of our U.K. subsidiaries. Additionally, outstanding borrowings under these sub-facilities may be up to 5.0% higher as allowed under the currency fluctuation provision in the 2015 Credit Agreement. Borrowings under the revolving credit facility bear interest at varying rates, based at our option, on either the applicable fixed rate plus 1.175% to 1.50% or the daily rate plus 0.175% to 0.50% as determined by reference to our ratio of total debt less available cash to EBITDA (as defined in the 2015 Credit Agreement). As of March 31, 2015, we had $110.0 million of revolving credit facility principal outstanding under the 2015 Credit Agreement with a related weighted average annual interest rate of 2.7%, which was included in short-term borrowings in the accompanying consolidated balance sheets. As of March 31, 2015, letters of credit totaling $4.0 million were outstanding under the revolving credit facility. 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 December 31, 2014, we had $4.8 million of revolving credit facility principal outstanding under the 2013 Credit Agreement with a related weighted average annual interest rate of 1.4%, which was included in short-term borrowings in the accompanying consolidated balance sheets.
	Borrowings under the tranche A term loan facility under the 2015 Credit Agreement as of March 31, 2015 bear interest, based on our option, on either the applicable fixed rate plus 1.375% to 1.85% or the daily rate plus 0.375% to 0.85%, as determined by reference to our ratio of total debt less available cash to EBITDA (as defined in the 2015 Credit Agreement). As of March 31, 2015, we had $500.0 million of term loan facility principal outstanding under the 2015 Credit Agreement, which was included in the accompanying consolidated balance sheets. As of December 31, 2014, we had $645.6 million of term loan facilities principal outstanding (including $434.4 million of tranche A term loan facility and $211.2 million of tranche B term loan facility) under the 2013 Credit Agreement, which are also included in the accompanying consolidated balance sheets.
	As of March 10, 2015, we obtained Investment Grade Status (as defined in the 2015 Credit Agreement). As such, upon delivery of our first quarter 2015 compliance certificate (due 45 days following the end of such quarter), borrowings under the revolving credit facility will bear interest at varying rates, based at our option, on either (1) the applicable fixed rate plus 0.85% to 1.00% or (2) the daily rate, in each case as determined by reference to our Credit Rating (as defined in the 2015 Credit Agreement). Borrowings under the tranche A term loan facility will bear interest, based on our option, on either (1) the applicable fixed rate plus 0.95% to 1.25% or (2) the daily rate plus 0.0% to 0.25%, in each case as determined by reference to our Credit Rating (as defined in the 2015 Credit Agreement).
	The 2015 Credit Agreement is jointly and severally guaranteed by us and substantially all of our material domestic subsidiaries. Borrowings under the 2015 Credit Agreement are secured by a pledge of substantially all of the capital stock of our U.S. subsidiaries and 65.0% of the capital stock of certain non-U.S. subsidiaries, in each case, held by us and the U.S. guarantor subsidiaries. Also, the 2015 Credit Agreement requires us to pay a fee based on the total amount of the unused revolving credit facility commitment.
	Our 2015 Credit Agreement and the indentures governing our 5.00% senior notes and 5.25% senior notes contain numerous restrictive covenants that, among other things, limit our ability to incur additional indebtedness, pay dividends or make distributions to stockholders, repurchase capital stock or debt, make investments, sell assets or subsidiary stock, create or permit liens on assets, engage in transactions with affiliates, enter into sale/leaseback transactions, issue subsidiary equity and enter into consolidations or mergers. Our 2015 Credit Agreement also currently requires us to maintain a minimum coverage ratio of EBITDA (as defined in the 2015 Credit Agreement) to total interest expense of 2.00x and a maximum leverage ratio of total debt less available cash to EBITDA (as defined in the 2015 Credit Agreement) of 4.25x as of the end of each fiscal quarter. Our coverage ratio of EBITDA to total interest expense was 13.02x for the trailing twelve months ended March 31, 2015 and our leverage ratio of total debt less available cash to EBITDA was 1.23x as of March 31, 2015.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	11. 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. Our management believes that any losses in excess of the amounts accrued arising from such lawsuits are unlikely to be significant, but that 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 that anticipated by management.
	In January 2008, CBRE Multifamily Capital, Inc. (CBRE MCI), a wholly-owned subsidiary of CBRE Capital Markets, entered into an agreement with Federal National Mortgage Association (Fannie Mae), under Fannie Mae’s DUS 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 in selected cases, 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 $10.6 billion at March 31, 2015. Additionally, CBRE MCI has funded loans under the DUS Program that are not subject to loss sharing arrangements with unpaid principal balances of approximately $91.4 million at March 31, 2015. 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 March 31, 2015 and December 31, 2014, CBRE MCI had a $32.0 million and a $29.0 million, respectively, letter of credit under this reserve arrangement, and had provided approximately $18.7 million and $16.8 million, respectively, of loan loss accruals. Fannie Mae’s recourse under the DUS Program is limited to the assets of CBRE MCI, which totaled approximately $855.6 million (including $710.2 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 March 31, 2015.
	We had outstanding letters of credit totaling $43.3 million as of March 31, 2015, excluding letters of credit for which we have outstanding liabilities already accrued on our consolidated balance sheet related to our subsidiaries’ outstanding reserves for claims under certain insurance programs as well as letters of credit related to operating leases. CBRE MCI’s letter of credit totaling $32.0 million referred to in the preceding paragraph represented the majority of the $43.3 million outstanding letters of credit. The remaining letters of credit are primarily executed by us in the ordinary course of business and expire at varying dates through December 2015.
	We had guarantees totaling $17.4 million as of March 31, 2015, 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 operating leases. The $17.4 million primarily represents guarantees of obligations of unconsolidated subsidiaries, which expire at varying dates through December 2018, as well as various guarantees of management contracts in our operations overseas, which expire at the end of each of the respective agreements.
	In addition, as of March 31, 2015, we had numerous completion and budget guarantees relating to development projects. These guarantees are made by us in the ordinary course of our Development Services business. Each of these guarantees requires 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 have “guaranteed maximum price” contracts with reputable 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 typically range from 2.0% to 5.0% of the equity in a particular fund. As of March 31, 2015, we had aggregate commitments of $16.5 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 March 31, 2015, we had committed to fund $22.0 million of additional capital to these unconsolidated subsidiaries.

	For the three months ended March 31, 2014, options to purchase 37,598 shares of common stock were excluded from the computation of diluted earnings per share. These options were excluded because their inclusion would have had an anti-dilutive effect given that the options’ exercise prices were greater than the average market price of our common stock for such period.

	EBITDA represents earnings before net interest expense, write-off of financing costs, income taxes, depreciation and amortization. Our management believes EBITDA is useful in evaluating our operating performance compared to that of other companies in our industry because the calculation of EBITDA generally eliminates the effects of financing and income taxes and the accounting effects of capital spending and acquisitions, which would include impairment charges of goodwill and intangibles created from acquisitions. Such items may vary for different companies for reasons unrelated to overall operating performance. As a result, our management uses EBITDA as a measure to evaluate the operating performance of our various business segments and for other discretionary purposes, including as a significant component when measuring our operating performance under our employee incentive programs. Additionally, we believe EBITDA is useful to investors to assist them in getting a more complete picture of our results of operations.
	However, EBITDA is not a recognized measurement under GAAP and when analyzing our operating performance, readers should use EBITDA in addition to, and not as an alternative for, net income as determined in accordance with GAAP. Because not all companies use identical calculations, our presentation of EBITDA may not be comparable to similarly titled measures of other companies. Furthermore, EBITDA is not intended to be a measure of free cash flow for our management’s discretionary use, as it does not consider certain cash requirements such as tax and debt service payments. The amounts shown for EBITDA also differ from the amounts calculated under similarly titled definitions in our debt instruments, which are further adjusted to reflect certain other cash and non-cash charges and are used to determine compliance with financial covenants and our ability to engage in certain activities, such as incurring additional debt and making certain restricted payments.
	Net interest expense and write-off of financing costs have been expensed in the segment incurred. Provision for income taxes has been allocated among our segments by using applicable U.S. and foreign effective tax rates. EBITDA for our segments is calculated as follows (dollars in thousands):

Entry Into Agreement To Purchase Global Workplace Solutions	16. Entry Into Agreement To Purchase Global Workplace Solutions
	On March 31, 2015, CBRE, Inc., our wholly-owned subsidiary, entered into a Stock and Asset Purchase Agreement with Johnson Controls, Inc. (JCI) to acquire JCI’s Global WorkPlace Solutions (GWS) business. GWS is a market-leading provider of Integrated Facilities Management solutions for major occupiers of commercial real estate and has significant operations around the world. The purchase price is $1.475 billion, payable in cash, with adjustments for working capital and other items. We expect to fund the acquisition through a combination of cash on hand and proceeds from the incurrence of debt. The closing of the transaction is subject to receipt of customary regulatory approvals and satisfaction of other customary closing conditions. The transaction is expected to close in the late third quarter or early fourth quarter of 2015.

Fair Value Disclosures [Abstract]
Fair Value Measurements and Disclosures	The “Fair Value Measurements and Disclosures” Topic of the FASB Accounting Standards Codification (ASC) (Topic 820) 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.
