Accounting Policies [Abstract]
Significant Accounting Policies	2. Significant Accounting Policies Principles of Consolidation The accompanying consolidated financial statements include our accounts and those of our consolidated subsidiaries, which are comprised of variable interest entities in which we are the primary beneficiary and voting interest entities, in which we determined we have a controlling financial interest, under the “ Consolidations non-controlling Variable Interest Entities (VIEs) We determine whether an entity is a VIE and, if so, whether it should be consolidated by utilizing judgments and estimates that are inherently subjective. Our determination of whether an entity in which we hold a direct or indirect variable interest is a VIE is based on several factors, including whether the entity’s total equity investment at risk upon inception is sufficient to finance the entity’s activities without additional subordinated financial support. We make judgments regarding the sufficiency of the equity at risk based first on a qualitative analysis, and then a quantitative analysis, if necessary. We analyze any investments in VIEs to determine if we are the primary beneficiary. In evaluating whether we are the primary beneficiary, we evaluate our direct and indirect economic interests in the entity. A reporting entity is determined to be the primary beneficiary if it holds a controlling financial interest in the VIE. Determining which reporting entity, if any, has a controlling financial interest in a VIE is primarily a qualitative approach focused on identifying which reporting entity has both (1) the power to direct the activities of a VIE that most significantly impact such entity’s economic performance and (2) the obligation to absorb losses or the right to receive benefits from such entity that could potentially be significant to such entity. Performance of that analysis requires the exercise of judgment. We consider a variety of factors in identifying the entity that holds the power to direct matters that most significantly impact the VIE’s economic performance including, but not limited to, the ability to direct financing, leasing, construction and other operating decisions and activities. In addition, we consider the rights of other investors to participate in those decisions, to replace the manager and to sell or liquidate the entity. We determine whether we are the primary beneficiary of a VIE at the time we become involved with a variable interest entity and reconsider that conclusion continually. We consolidate any VIE of which we are the primary beneficiary and disclose significant VIEs of which we are not the primary beneficiary, if any, as well as disclose our maximum exposure to loss related to VIEs that are not consolidated (see Note 4). Voting Interest Entities (VOEs) For VOEs, we consolidate the entity if we have a controlling financial interest. We have a controlling financial interest in a VOE if (i) for legal entities other than limited partnerships, we own a majority voting interest in the VOE or, for limited partnerships and similar entities, we own a majority of the entity’s kick-out (ii) non-controlling Other Investments Our investments in unconsolidated subsidiaries in which we have the ability to exercise significant influence over operating and financial policies, but do not control, or entities which are variable interest entities in which we are not the primary beneficiary are accounted for under the equity method. We eliminate transactions with such equity method subsidiaries to the extent of our ownership in such subsidiaries. Accordingly, our share of the earnings from these equity-method basis companies is included in consolidated net income. All other investments held on a long-term basis are valued at cost less any impairment in value. Impairment Evaluation Under either the equity or cost method, impairment losses are recognized upon evidence of other-than-temporary losses of value. When testing for impairment on investments that are not actively traded on a public market, we generally use a discounted cash flow approach to estimate the fair value of our investments and/or look to comparable activities in the marketplace. Management’s judgment is required in developing the assumptions for the discounted cash flow approach. These assumptions include net asset values, internal rates of return, discount and capitalization rates, interest rates and financing terms, rental rates, timing of leasing activity, estimates of lease terms and related concessions, etc. When determining if impairment is other-than-temporary, we also look to the length of time and the extent to which fair value has been less than cost as well as the financial condition and near-term prospects of each investment. Use of Estimates Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S.), or GAAP, which require management to make estimates and assumptions about future events. These estimates and assumptions affect the amounts of assets, liabilities, revenue and expenses we report. Such estimates include the value of goodwill, intangibles and other long-lived 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, and are evaluated on an ongoing basis and adjusted, as needed, using historical experience and other factors, including consideration of the macroeconomic environment. As future events and their effects cannot be forecast with precision, actual results could differ significantly from these estimates. Changes in estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods. Cash and Cash Equivalents Cash and cash equivalents generally consist of cash and highly liquid investments with an original maturity of three months or less. Included in the accompanying consolidated balance sheets as of December 31, 2016 and 2015 is cash and cash equivalents of $73.3 million and $70.2 million, respectively, from consolidated funds and other entities, which are not available for general corporate use. We also manage certain cash and cash equivalents as an agent for our investment and property and facilities management clients. These amounts are not included in the accompanying consolidated balance sheets (see Note 16). Restricted Cash Included in the accompanying consolidated balance sheets as of December 31, 2016 and 2015 is restricted cash of $68.8 million and $72.8 million, respectively. The balances primarily include restricted cash set aside to cover funding obligations as required by contracts executed by us in the ordinary course of business. Concentration of Credit Risk Financial instruments that potentially subject us to credit risk consist principally of trade receivables and interest-bearing investments. Users of real estate services account for a substantial portion of trade receivables and collateral is generally not required. The risk associated with this concentration is limited due to the large number of users and their geographic dispersion. We place substantially all of our interest-bearing investments with several major financial institutions to limit the amount of credit exposure with any one financial institution. Property and Equipment Property and equipment, which includes leasehold improvements, is stated at cost, net of accumulated depreciation. Depreciation and amortization of property and equipment is computed primarily using the straight-line method over estimated useful lives ranging up to 10 years. Leasehold improvements are amortized over the term of their associated leases, excluding options to renew, since such leases generally do not carry prohibitive penalties for non-renewal. We review property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If this review indicates that such assets are considered to be impaired, the impairment is recognized in the period the changes occur and represents the amount by which the carrying value exceeds the fair value of the asset. Certain costs related to the development or purchase of internal-use Internal-use Goodwill and Other Intangible Assets Our acquisitions require the application of purchase accounting, which results in tangible and identifiable intangible assets and liabilities of the acquired entity being recorded at fair value. The difference between the purchase price and the fair value of net assets acquired is recorded as goodwill. The majority of our goodwill balance has resulted from our acquisition of CBRE Services, Inc. (CBRE Services) in 2001 (the 2001 Acquisition), our acquisition of Insignia Financial Group, Inc. (Insignia) in 2003 (the Insignia Acquisition), our acquisition of the Trammell Crow Company in 2006 (the Trammell Crow Company Acquisition), our acquisition of substantially all of the ING Group N.V. (ING) Real Estate Investment Management (REIM) operations in Europe and Asia, as well as substantially all of Clarion Real Estate Securities (CRES) in 2011 (collectively referred to as the REIM Acquisitions), our acquisition of Norland Managed Services Ltd (Norland) in 2013 (the Norland Acquisition) and our acquisition of Johnson Controls, Inc. (JCI)’s Global Workplace Solutions (JCI-GWS) We are required to test goodwill and other intangible assets deemed to have indefinite useful lives for impairment at least annually, or more often if circumstances or events indicate a change in the impairment status. The goodwill impairment analysis is a two-step Deferred Financing Costs Costs incurred in connection with financing activities are generally deferred and amortized over the terms of the related debt agreements ranging up to ten years. Debt issuance costs related to a recognized debt liability are presented in the accompanying consolidated balance sheets as a direct deduction from the carrying amount of that debt liability. Amortization of these costs is charged to interest expense in the accompanying consolidated statements of operations. Accounting Standards Update (ASU) 2015-15, “Interest—Imputation of Interest (Subtopic 835-30): Line-of-Credit On March 21, 2016, we executed an amendment to our amended and restated credit agreement which, among other things, extended the maturity on our revolving credit facility and increased the borrowing capacity under our revolving credit facility. In connection with this amendment, we incurred approximately $5.4 million of financing costs. During 2015, we entered into an amended and restated credit agreement providing for a $500.0 million tranche A term loan facility and a $2.6 billion revolving credit facility. In addition, we added new tranche B-1 B-2 write-off During 2014, we completed three financing transactions, which included the issuance in September and December of $300.0 million and $125.0 million, respectively, in aggregate principal amount of 5.25% senior notes due March 15, 2025 and the redemption in October 2014 of all of the then outstanding 6.625% senior notes (aggregate principal amount of $350.0 million). During the year ended December 31, 2014, in connection with these financing activities, we incurred approximately $4.7 million of financing costs. In addition, we expensed $5.7 million of previously-deferred financing costs as well as a $17.4 million early extinguishment premium, all of which were included in write-off See Note 10 for additional information on activities associated with our debt. Revenue Recognition We record commission revenue on real estate sales generally upon close of escrow or transfer of title, except when future contingencies exist. Real estate commissions on leases are generally recorded in revenue when all obligations under the commission agreement are satisfied. Terms and conditions of a commission agreement may include, but are not limited to, execution of a signed lease agreement and future contingencies including tenant occupancy, payment of a deposit or payment of a first month’s rent (or a combination thereof). A commission agreement may provide that we earn a portion of a lease commission upon the execution of the lease agreement by the tenant and landlord, with the remaining portion(s) of the lease commission earned at a later date, usually upon tenant occupancy or payment of rent. The existence of any significant future contingencies results in the delay of recognition of corresponding revenue until such contingencies are satisfied. For example, if we do not earn all or a portion of the lease commission until the tenant pays its first month’s rent, and the lease agreement provides the tenant with a free rent period, we delay revenue recognition until rent is paid by the tenant. As some of these conditions are outside of our control and are often not clearly defined, judgment must be exercised in determining when such required events have occurred in order to recognize revenue. Property and facilities management revenues are generally based on measures consistent with the terms of the customer contracts. These contracts are negotiated utilizing a variety of terms covering various lengths of time. The fees are recognized when earned under the provisions of the related agreements. We also may earn revenue based on certain qualitative and quantitative performance measures. We recognize this revenue when the performance has been completed, the measure has been calculated and fees are deemed collectible. Our clients reimburse us for certain expenses incurred on their behalf, primarily in our property and facilities management operations. Our treatment of these reimbursements is based upon the terms of the underlying contract. We use certain indicators as to whether we record the reimbursements on a gross versus net basis, such as whether we are the primary obligor on the contracts, whether the contract is based on a fixed fee, credit risk and our discretion in making vendor selections and establishing prices. In certain instances, we have determined we are acting as the principal in the transaction and, accordingly, report these reimbursements as revenue on a gross basis with the total costs reflected in cost of services. Reimbursement revenue is recognized when the underlying reimbursable costs are incurred. When we determine we are not the primary obligor and are acting as an agent, we account for the transaction on a net basis. Investment management fees are based predominantly upon a percentage of the equity deployed on behalf of our limited partners. Fees related to our indirect investment management programs are based upon a percentage of the fair value of those investments. These fees are recognized when earned under the provisions of the related investment management agreements. Our Global Investment Management segment earns performance-based incentive fees with regard to many of its investments. Such revenue is recognized at the end of the measurement periods when the conditions of the applicable incentive fee arrangements have been satisfied and following the expiration of any potential claw back provision. With many of these investments, our Global Investment Management professionals have participation interests in such incentive fees, which are commonly referred to as carried interest. This carried interest expense is generally accrued for based upon the probability of such performance-based incentive fees being earned over the related vesting period. In addition, our Global Investment Management segment also earns success-based transaction fees with regard to buying or selling properties on behalf of certain funds and separate accounts. Such revenue is recognized at the completion of a successful transaction and is not subject to any claw back provision. Appraisal fees are recorded after services have been rendered. Loan origination fees are recognized at the time a loan closes and we have no significant remaining obligations for performance in connection with the transaction, while loan servicing fees are recorded in revenue as monthly principal and interest payments are collected from mortgagors. Other commissions, consulting fees and referral fees are recorded as revenue at the time the related services have been performed, unless future contingencies exist. Development services and project management services generate fees from development and construction management projects. Most development and construction management and project management assignments are subject to agreements that describe the calculation of fees and when we earn such fees. The earnings terms of these agreements dictate when we recognize the related revenue. Generally, development fees are recognized based on the lower of the amount billed or the amount determined on a straight-line basis over the development period. We may earn incentive fees for project management services based upon achievement of certain performance criteria as set forth in the project management services agreement. Incentive development fees are recognized when quantitative criteria have been met (such as specified leasing, budget or time-based targets) or for those incentive fees based on qualitative criteria, upon approval of the fee by our clients. Certain incentive development fees allow us to share in the fair value of the developed real estate asset above cost. This sharing creates additional revenue potential to us with no exposure to loss other than opportunity cost. We recognize such fees when the specified target is attained and fees are deemed collectible. We record deferred income to the extent that cash payments have been received in accordance with the terms of underlying agreements, but such amounts have not yet met the criteria for revenue recognition in accordance with generally accepted accounting principles. We recognize such revenues when the appropriate criteria are met. In establishing the appropriate provisions for trade receivables, we make assumptions with respect to future collectability. Our assumptions are based on an assessment of a customer’s credit quality as well as subjective factors and trends, including the aging of receivables balances. In addition to these assessments, in general, outstanding trade accounts receivable amounts that are more than 180 days overdue are evaluated for collectability and fully provided for if deemed uncollectible. Historically, our credit losses have generally been insignificant. However, estimating losses requires significant judgment, and conditions may change or new information may become known after any periodic evaluation. As a result, actual credit losses may differ from our estimates. Business Promotion and Advertising Costs The costs of business promotion and advertising are expensed as incurred. Business promotion and advertising costs of $65.8 million, $62.7 million and $55.6 million were included in operating, administrative and other expenses for the years ended December 31, 2016, 2015 and 2014, respectively. Foreign Currencies The financial statements of subsidiaries located outside the U.S. are generally measured using the local currency as the functional currency. The assets and liabilities of these subsidiaries are translated at the rates of exchange at the balance sheet date, and income and expenses are translated at the average monthly rate. The resulting translation adjustments are included in the accumulated other comprehensive loss component of equity. Gains and losses resulting from foreign currency transactions are included in the results of operations. Derivative Financial Instruments and Hedging Activities As required by FASB ASC Topic 815 “ Derivatives and Hedging Comprehensive Income Comprehensive income consists of net income and other comprehensive loss. In the accompanying consolidated balance sheets, accumulated other comprehensive loss consists of foreign currency translation adjustments, fees associated with the termination of interest rate swaps, unrealized losses on interest rate swaps, unrealized holding gains (losses) on available for sale securities and pension liability adjustments. Foreign currency translation adjustments exclude any income tax effect given that earnings of non-U.S. Marketable Securities We account for investments in marketable debt and equity securities in accordance with the “ Investments – Debt and Equity Securities Trading securities are carried at their fair value with realized and unrealized gains and losses included in net income. Available for sale securities are carried at their fair value and any difference between cost and fair value is recorded as unrealized gain or loss, net of income taxes, and is reported as accumulated other comprehensive loss in the consolidated statement of equity. Premiums and discounts are recognized in interest using the effective interest method. Realized gains and losses and declines in value expected to be other-than-temporary on available for sale securities have not been significant. The cost of securities sold is based on the specific identification method. Interest and dividends on securities classified as available for sale are included in interest income. For investments classified as available for sale, we assess impairment at the individual security level. An investment is impaired if the fair value of the investment is less than its amortized cost basis. When an impairment exists, we assess whether such impairment is temporary or other-than-temporary. We review the volatility and intended holding period of our investments and also determine if we believe that there is a reasonable possibility that the value would be recovered over the intended holding period. Based on our review, we did not record any significant other-than-temporary impairment losses during the years ending December 31, 2016, 2015 and 2014. Warehouse Receivables 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 is a U.S. Department of Housing and Urban Development (HUD) approved Non-Supervised one-month Mortgage Servicing Rights In connection with the origination and sale of mortgage loans with servicing rights retained, we record servicing assets or liabilities based on the fair value of the mortgage servicing rights on the date the loans are sold. We also assume or purchase certain servicing assets. Our mortgage service rights (MSRs) are initially recorded at fair value. Subsequent to the initial recording, MSRs are amortized and carried at the lower of amortized cost or fair value in other intangible assets in the accompanying consolidated balance sheets. They are amortized in proportion to and over the estimated period that net servicing income is expected to be received based on projections and timing of estimated future net cash flows. Our initial recording of MSRs at their fair value resulted in net gains, as the fair value of servicing contracts that result in MSR assets exceeded the fair value of servicing contracts that result in MSR liabilities. The net assets and net gains are presented in the accompanying consolidated financial statements. The amount of MSRs recognized during the years ended December 31, 2016 and 2015 was as follows (dollars in thousands): Year Ended December 31, 2016 2015 Beginning balance, mortgage servicing rights $ 244,723 $ 202,982 Mortgage servicing rights recognized 154,040 110,428 Mortgage servicing rights sold (790 ) (783 ) Amortization expense (73,273 ) (59,608 ) Other (4,176 ) (8,296 ) Ending balance, mortgage servicing rights $ 320,524 $ 244,723 Mortgage servicing rights do not actively trade in an open market with readily available observable prices; therefore, fair value is determined based on certain assumptions and judgments, including the estimation of the present value of future cash flows realized from servicing the underlying mortgage loans. Management’s assumptions include the benefits of servicing (servicing fee income and interest on escrow deposits), inflation, the cost of servicing, prepayment rates, delinquencies, discount rates and the estimated life of servicing cash flows. The assumptions used are subject to change based on management’s judgments and estimates of changes in future cash flows and interest rates, among other things. The key assumptions used during the years ended December 31, 2016, 2015 and 2014 in measuring fair value were as follows: Year Ended December 31, 2016 2015 2014 Discount rate 10.16 % 10.11 % 10.38 % Conditional prepayment rate 9.66 % 6.03 % 6.14 % The estimated fair value of our mortgage servicing rights was $375.5 million and $301.2 million as of December 31, 2016 and 2015, respectively. Impairment is evaluated through a comparison of the carrying amount and fair value of the MSRs, and recognized with the establishment of a valuation allowance. We did not incur any impairment charges related to our MRSs during the years ended December 31, 2016, 2015 or 2014. No valuation allowance was created previously and we did not record a valuation allowance for MSRs in 2016 or 2015. Included in revenue in the accompanying consolidated statements of operations are contractually specified servicing fees from loans serviced for others of $104.2 million, $78.9 million and $65.2 million for the years ended December 31, 2016, 2015 and 2014, respectively, and prepayment fees/late fees/ancillary income earned from loans serviced for others of $7.2 million, $8.4 million and $6.1 million for the years ended December 31, 2016, 2015 and 2014, respectively. Accounting for Broker Draws As part of our recruitment efforts relative to new U.S. brokers, we offer a transitional broker draw arrangement. Our broker draw arrangements generally last until such time as a broker’s pipeline of business is sufficient to allow him or her to earn sustainable commissions. This program is intended to provide the broker with a minimal amount of cash flow to allow adequate time for his or her training as well as time for him or her to develop business relationships. Similar to traditional salaries, the broker draws are paid irrespective of the actual revenues generated by the broker. Often these broker draws represent the only form of compensation received by the broker. Furthermore, it is not our general policy to pursue collection of unearned broker draws paid under this arrangement. As a result, we have concluded that broker draws are economically equivalent to salaries paid and accordingly charge them to compensation expense as incurred. The broker is also entitled to earn a commission on completed revenue transactions. This amount is calculated as the commission that would have been payable under our full commission program, less any amounts previously paid to the broker in the form of a draw. Stock-Based Compensation We account for all employee awards under the fair value recognition provisions of the “ Compensation – Stock Compensation In the third quarter of 2016, we elected to early adopt the provisions of ASU 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting,” 2016-09 paid-in 2016-09 See Note 12 for additional information on our stock-based compensation plans. Income Per Share Basic income per share attributable to CBRE Group, Inc. is computed by dividing net income attributable to CBRE Group, Inc. shareholders by the weighted average number of common shares outstanding during each period. The computation of diluted income per share attributable to CBRE Group, Inc. generally further assumes the dilutive effect of potential common shares, which include stock options and certain contingently issuable shares. Contingently issuable shares consist of non-vested Income Taxes Income taxes are accounted for under the asset and liability method in accordance with the “ Accounting for Income Taxes Self-Insurance Our wholly-owned captive insurance company, which is subject to applicable insurance rules and regulations, insures our exposure related to workers’ compensation insurance, general liability insurance and automotive insurance for our U.S. operations risk on a primary basis and we purchase excess coverage from unrelated insurance carriers. The captive insurance company also insures primary risk relating to professional indemnity claims globally. Given the nature of these types of claims, it may take several years for resolution and determination of the cost of these claims. We are required to estimate the cost of these claims in our financial statements. The estimates that we utilize to record our potential losses on claims are inherently subjective, and actual claims could differ from amounts recorded, which could result in increased or decreased expense in future periods. As of December 31, 2016 and 2015, our reserves for claims under these insurance programs were $80.6 million and $73.8 million, respectively, of which $1.7 million and $1.9 million, respectively, represented our estimated current liabilities. New Accounting Pronouncements Recent Accounting Pronouncements Pending Adoption The FASB has recently issued five ASUs related to revenue recognition (“new revenue recognition guidance”), all of which become effective for the company on January 1, 2018. The ASUs issued are: (1) in May 2014, ASU 2014-09, “Revenue from Contracts with Customers (Topic 606);” ASU 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net);” 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing;” 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-scope Improvements and Practical Expedients;” 2016-20, “Technical Corrections and Improvements to Topic 606, Revenue From Contracts with Customers.” 2014-09 2016-08 2016-10 2014-09. 2016-12 2016-20 We plan to adopt the new revenue recognition guidance in the first quarter of 2018 and are evaluating the application of a transition method. We continue to evaluate the impact that adoption of these updates will have on our consolidated financial statements. Based on our initial assessment, the impact of the application of the new revenue recognition guidance will likely result in an acceleration of some revenues that are based, in part, on future contingent events. We are currently evaluating the impact of principal versus agent guidance in relation to third-party costs which are billed to clients in association with facilities management services and the impact, if any, on our consolidated financial statements.

Business Combinations [Abstract]
Acquisition of Global Workplace Solutions (GWS)	3. Acquisition of Global Workplace Solutions (GWS) On September 1, 2015, CBRE, Inc., our wholly-owned subsidiary, pursuant to a Stock and Asset Purchase Agreement with JCI, acquired JCI’s GWS business (we refer to as the GWS Acquisition). The acquired JCI-GWS JCI-GWS We financed the transaction with: (i) a new issuance in August 2015 of $600.0 million in aggregate principal amount of 4.875% senior notes due March 1, 2026; (ii) borrowings in September 2015 of $400.0 million in aggregate principal amount of new tranche B-1 B-2 The purchase accounting for the GWS Acquisition, including assignment of goodwill to our reporting units, has been finalized. There were no significant adjustments to the purchase price allocation recorded during the year ended December 31, 2016. The excess purchase price over the estimated fair value of net assets acquired of $796 million has been recorded to goodwill, with $406 million assigned to our Americas segment, $378 million assigned to our EMEA segment and $12 million assigned to our Asia Pacific segment. The goodwill arising from the GWS Acquisition consists largely of the synergies and economies of scale expected from combining the operations acquired from JCI with our business.

Fair Value Measurements	5. Fair Value Measurements The “Fair Value Measurements and Disclosures” • 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 years ended December 31, 2016 and 2015. The following tables present the fair value of assets and liabilities measured at fair value on a recurring basis as of December 31, 2016 and 2015 (dollars in thousands): As of December 31, 2016 Fair Value Measured and Recorded Using Level 1 Level 2 Level 3 Total Assets Available for sale securities: Debt securities: U.S. treasury securities $ 8,485 $ — $ — $ 8,485 Debt securities issued by U.S. federal agencies — 5,046 — 5,046 Corporate debt securities — 17,094 — 17,094 Asset-backed securities — 2,695 — 2,695 Collateralized mortgage obligations — 1,010 — 1,010 Total debt securities 8,485 25,845 — 34,330 Equity securities 22,744 — — 22,744 Total available for sale securities 31,229 25,845 — 57,074 Trading securities 52,629 — — 52,629 Warehouse receivables — 1,276,047 — 1,276,047 Foreign currency exchange forward contracts — 1,471 — 1,471 Total assets at fair value $ 83,858 $ 1,303,363 $ — $ 1,387,221 Liabilities Interest rate swaps $ — $ 13,162 $ — $ 13,162 Securities sold, not yet purchased 3,591 — — 3,591 Total liabilities at fair value $ 3,591 $ 13,162 $ — $ 16,753 As of December 31, 2015 Fair Value Measured and Recorded Using Level 1 Level 2 Level 3 Total Assets Available for sale securities: Debt securities: U.S. treasury securities $ 7,350 $ — $ — $ 7,350 Debt securities issued by U.S. federal agencies — 3,360 — 3,360 Corporate debt securities — 18,085 — 18,085 Asset-backed securities — 1,897 — 1,897 Collateralized mortgage obligations — 1,752 — 1,752 Total debt securities 7,350 25,094 — 32,444 Equity securities 24,118 — — 24,118 Total available for sale securities 31,468 25,094 — 56,562 Trading securities 64,124 — — 64,124 Warehouse receivables — 1,767,107 — 1,767,107 Loan commitments — — 1,680 1,680 Foreign currency exchange forward contracts — 9,236 — 9,236 Total assets at fair value $ 95,592 $ 1,801,437 $ 1,680 $ 1,898,709 Liabilities Interest rate swaps $ — $ 21,502 $ — $ 21,502 Securities sold, not yet purchased 4,436 — — 4,436 Foreign currency exchange forward contracts — 1,008 — 1,008 Total liabilities at fair value $ 4,436 $ 22,510 $ — $ 26,946 The fair values of the warehouse receivables are calculated based on already locked in security buy prices. At December 31, 2016 and 2015, 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 (See Note 2). These assets are classified as Level 2 in the fair value hierarchy as all inputs are readily observable. The valuation of interest rate swaps and foreign currency exchange forward contracts is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate and foreign currency exchange forward curves. The fair values of interest rate swaps and foreign currency exchange forward contracts are determined using the market standard methodology of netting the discounted future estimated cash payments/receipts. The estimated cash flows are based on an expectation of future interest rates or foreign currency exchange rates using forward curves derived from observable market interest rate and foreign currency exchange forward curves. The valuation of our loan commitments is determined using discounted cash flow analysis on the expected cash flows of each derivative. The primary source of value of each written loan commitment is future servicing rights. Mortgage servicing rights do not actively trade in an open market with readily available observable prices; therefore, fair value is determined based on certain assumptions and judgments, including the estimation of the present value of future cash flows realized from servicing the underlying mortgage loans (see Note 2). As such, our loan commitments are classified in Level 3 in the fair value hierarchy. The following table provides additional information about fair value measurements for these Level 3 assets for the years ended December 31, 2016 and 2015 (dollars in thousands): Year Ended December 31, 2016 2015 Beginning balance $ 1,680 $ 2,372 Net gains included in earnings 31,400 21,709 Settlements (33,080 ) (22,401 ) Ending balance $ — $ 1,680 Fair value measurements for our available for sale securities are obtained from independent pricing services which utilize observable market data that may include quoted market prices, dealer quotes, market spreads, cash flows, the U.S. treasury yield curve, trading levels, market consensus prepayment speeds, credit information and the instrument’s terms and conditions. The trading securities and securities sold, not yet purchased are primarily in the U.S. and are generally valued at the last reported sales price on the day of valuation or, if no sales occurred on the valuation date, at the mean of the bid and asked prices on such date.

Derivative Financial Instrument

Derivative Financial Instruments	12 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	6. 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 July 2015, we entered into three interest rate swap agreements with an aggregate notional amount of $300.0 million, all with effective dates in August 2015, and designated them as cash flow hedges in accordance with FASB ASC Topic 815, “ Derivatives and Hedging 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. 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 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 years ended December 31, 2016, 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 $10.7 million, $11.9 million and $12.0 million for the years ended December 31, 2016, 2015, and 2014, respectively, from accumulated other comprehensive loss to interest expense. During the next twelve months, we estimate that $7.8 million will be reclassified from accumulated other comprehensive loss to interest expense. In addition, we recorded net losses of $2.4 million, $6.5 million and $9.9 million for the years ended December 31, 2016, 2015 and 2014, respectively, to other comprehensive loss in relation to such interest rate swap agreements. As of December 31, 2016 and 2015, the fair values of such interest rate swap agreements were reflected as a $13.2 million liability and a $21.5 million liability, respectively, and were included in other 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 (reporting) currency, which is U.S. dollars. 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 (which expired in December 2016) by entering into foreign currency exchange forward contracts, including agreements to buy U.S. dollars and sell Australian dollars, British pound sterling, Canadian dollars, euros and Japanese yen. The purpose of these forward contracts was 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 were recorded directly in earnings. Included in the consolidated statement of operations were net gains of $7.7 million, $24.2 million and $5.3 million for the years ended December 31, 2016, 2015 and 2014, respectively, resulting from net gains on foreign currency exchange forward contracts. As of December 31, 2016, we had no foreign currency exchange forward contracts outstanding as the program has expired. As of December 31, 2015, the fair value of forward contracts with six counterparties aggregated to an $8.9 million asset position, which was included in other current assets in the accompanying consolidated balance sheets. As of December 31, 2015, the fair value of forward contracts with two counterparties aggregated to a $1.1 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. The net impact on our financial position and earnings resulting from these foreign currency exchange forward and options contracts has not been significant.

Long-Term Debt We maintain credit facilities with third-party lenders, which we use for a variety of purposes. On March 28, 2013, CBRE Services, our wholly-owned subsidiary, entered into a credit agreement (2013 Credit Agreement) with a syndicate of banks led by Credit Suisse AG (CS) as administrative and collateral agent, to completely refinance a previous credit agreement. On January 9, 2015, CBRE Services entered into an amended and restated credit agreement (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 balance on our revolving credit facility under the 2013 Credit Agreement. On September 3, 2015, CBRE Services entered into an incremental assumption agreement with a syndicate of banks jointly led by Wells Fargo Securities, LLC and CS to establish new tranche B-1 B-2 The 2015 Credit Agreement is an unsecured credit facility that is jointly and severally guaranteed by us and substantially all of our material domestic subsidiaries. As of December 31, 2016, the 2015 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 March 21, 2021; (2) a $500.0 million tranche A term loan facility requiring quarterly principal payments, which began on June 30, 2015 and continue through maturity on January 9, 2020; (3) a $270.0 million tranche B-1 B-2 Borrowings under the term loan facilities under the 2015 Credit Agreement as of December 31, 2016 bear interest, based at our option, on the following: for the tranche A term loan facility, 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); for the tranche B-1 B-2 B-1 B-2 B-1 B-2 B-1 B-2 On August 13, 2015, CBRE Services issued $600.0 million in aggregate principal amount of 4.875% senior notes due March 1, 2026 at a price equal to 99.24% of their face value. The 4.875% senior notes are 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 4.875% senior notes are jointly and severally guaranteed on a senior basis by us and each domestic subsidiary of CBRE Services that guarantees our 2015 Credit Agreement. Interest accrues at a rate of 4.875% per year and is payable semi-annually in arrears on March 1 and September 1, with the first interest payment made on March 1, 2016. The 4.875% senior notes are redeemable at our option, in whole or in part, prior to December 1, 2025 at a redemption price equal to the greater of (1) 100% of the principal amount of the 4.875% senior notes to be redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest thereon to December 1, 2025 (not including any portions of payments of interest accrued as of the date of redemption) discounted to the date of redemption on a semi-annual basis at the Adjusted Treasury Rate (as defined in the indenture governing these notes). In addition, at any time on or after December 1, 2025, the 4.875% senior notes may be redeemed by us, in whole or in part, at a redemption price equal to 100.0% of the principal amount, plus accrued and unpaid interest, if any, to (but excluding) the date of redemption. If a change of control triggering event (as defined in the indenture governing these notes) occurs, we are obligated to make an offer to purchase the then outstanding 4.875% senior notes at a redemption price of 101.0% of the principal amount, plus accrued and unpaid interest, if any, to the date of purchase. The amount of the 4.875% senior notes, net of unamortized discount and unamortized debt issuance costs, included in the accompanying consolidated balance sheets was $591.2 million and $590.5 million at December 31, 2016 and 2015, respectively.

The 5.25% senior notes are 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 5.25% senior notes are jointly and severally guaranteed on a senior basis by us and each domestic subsidiary of CBRE Services that guarantees our 2015 Credit Agreement. Interest accrues at a rate of 5.25% per year and is payable semi-annually in arrears on March 15 and September 15, with the first interest payment made on March 15, 2015.

In addition, at any time on or after December 15, 2024, the 5.25% senior notes may be redeemed by us, in whole or in part, at a redemption price equal to 100.0% of the principal amount, plus accrued and unpaid interest, if any, to (but excluding) the date of redemption. If a change of control triggering event (as defined in the indenture governing these notes) occurs, we are obligated to make an offer to purchase the then outstanding 5.25% senior notes at a redemption price of 101.0% of the principal amount, plus accrued and unpaid interest, if any, to the date of purchase.

The 5.00% senior notes are redeemable at our option, in whole or in part, on or after March 15, 2018 at a redemption price of 102.5% of the principal amount on that date and at declining prices thereafter. At any time prior to March 15, 2016, we could have redeemed up to 35.0% of the original principal amount of the 5.00% senior notes using the net cash proceeds from certain public offerings, which we did not elect to do. In addition, at any time prior to March 15, 2018, the 5.00% senior notes may be redeemed by us, in whole or in part, at a redemption price equal to 100.0% of the principal amount, plus accrued and unpaid interest, if any, to the date of redemption, and an applicable premium (as defined in the indenture governing these notes), which is based on the excess of the present value of the March 15, 2018 redemption price plus all remaining interest payments through March 15, 2018, over the principal amount of the 5.00% senior notes on such redemption date. If a change of control triggering event (as defined in the indenture governing these notes) occurs, we are obligated to make an offer to purchase the then outstanding 5.00% senior notes at a redemption price of 101.0% of the principal amount, plus accrued and unpaid interest, if any.

Our 2015 Credit Agreement and the indentures governing our 5.00% senior notes, 4.875% senior notes and 5.25% senior notes contain 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 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. On this basis, our coverage ratio of EBITDA to total interest expense was 12.73x for the year ended December 31, 2016, and our leverage ratio of total debt less available cash to EBITDA was 1.18x as of December 31, 2016. On October 8, 2010, CBRE Services issued $350.0 million in aggregate principal amount of 6.625% senior notes due October 15, 2020.

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. 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.

CBRE MCI’s letter of credit totaling $45.0 million as of December 31, 2016 referred to in the preceding paragraph represented the majority of the $50.9 million outstanding letters of credit as of such date. The remaining letters of credit are primarily executed by us in the ordinary course of business and expire at varying dates through November 2017. We had guarantees totaling $56.6 million as of December 31, 2016, 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.

As of December 31, 2016, there were also deferred tax assets before valuation allowances of approximately $2.9 million related to state NOLs as well as $48.6 million related to foreign NOLs. The state and foreign NOLs both begin to expire in 2017, but the majority carry forward indefinitely. The utilization of NOLs may be subject to certain limitations under U.S. federal, state and foreign laws. In addition, as of December 31, 2016, we had $54.0 million of foreign income tax credits that can be utilized to offset U.S. federal income taxes on foreign-sourced earnings. These credits are scheduled to expire in 2023. We determined that as of December 31, 2016, $105.5 million of deferred tax assets do not satisfy the realization criteria set forth in Topic 740. Accordingly, a valuation allowance has been recorded for this amount. If released, the entire amount would result in a benefit to continuing operations. During the year ended December 31, 2016, our valuation allowance increased by approximately $13.9 million. This resulted from establishment of valuation allowances of $16.9 million related to non-U.S. non-U.S. Our foreign subsidiaries have accumulated $1.9 billion of undistributed earnings for which we have not recorded a deferred tax liability. Although tax liabilities might result from dividends being paid out of these earnings, or as a result of a sale or liquidation of non-U.S. non-U.S. non-U.S. The total amount of gross unrecognized tax benefits was approximately $94.9 million and $92.5 million as of December 31, 2016 and 2015, respectively. The total amount of unrecognized tax benefits that would affect our effective tax rate, if recognized, is $39.1 million ($35.7 million, net of federal benefit received from state positions) and $43.8 million ($40.7 million, net of federal benefit received from state positions) as of December 31, 2016 and 2015, respectively. A reconciliation of the beginning and ending amount of unrecognized tax benefits for the years ended December 31, 2016 and 2015 is as follows (dollars in thousands): Year Ended December 31, 2016 2015 Beginning balance, unrecognized tax benefits $ (92,538 ) $ (66,984 ) Gross increases—tax positions in prior period (514 ) (17,545 ) Gross decreases—tax positions in prior period 358 92 Gross increases—current-period tax positions (4,237 ) (8,792 ) Decreases relating to settlements 2,541 — Reductions as a result of lapse of statute of limitations 235 688 Foreign exchange movement (760 ) 3 Ending balance, unrecognized tax benefits $ (94,915 ) $ (92,538 ) We believe it is reasonably possible that between $61.6 million and $63.1 million of gross unrecognized tax benefits will be settled during the next twelve months due to filing amended returns and settling ongoing exams. Our continuing practice is to recognize potential accrued interest and/or penalties related to income tax matters within income tax expense. During the years ended December 31, 2016, 2015 and 2014, we accrued an additional $2.9 million, $3.2 million and $3.0 million, respectively, in interest and penalties associated with uncertain tax positions. During the year ended December 31, 2014, we reversed $10.5 million of accrued interest and penalties related to settled positions. As of December 31, 2016 and 2015, we have recognized a liability for interest and penalties of $31.7 million ($24.3 million, net of related federal benefit received from interest expense) and $28.8 million ($22.1 million, net of related federal benefit received from interest expense), respectively. We conduct business globally and, as a result, one or more of our subsidiaries files income tax returns in the U.S. federal jurisdiction and in multiple state, local and foreign jurisdictions. We are no longer open to assessment by the U.S. Internal Revenue Service for years prior to 2005. With limited exception, our significant state and foreign tax jurisdictions are no longer subject to audit by the various tax authorities for tax years prior to 2007.

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include our accounts and those of our consolidated subsidiaries, which are comprised of variable interest entities in which we are the primary beneficiary and voting interest entities, in which we determined we have a controlling financial interest, under the “ Consolidations non-controlling Variable Interest Entities (VIEs) We determine whether an entity is a VIE and, if so, whether it should be consolidated by utilizing judgments and estimates that are inherently subjective. Our determination of whether an entity in which we hold a direct or indirect variable interest is a VIE is based on several factors, including whether the entity’s total equity investment at risk upon inception is sufficient to finance the entity’s activities without additional subordinated financial support. We make judgments regarding the sufficiency of the equity at risk based first on a qualitative analysis, and then a quantitative analysis, if necessary. We analyze any investments in VIEs to determine if we are the primary beneficiary. In evaluating whether we are the primary beneficiary, we evaluate our direct and indirect economic interests in the entity. A reporting entity is determined to be the primary beneficiary if it holds a controlling financial interest in the VIE. Determining which reporting entity, if any, has a controlling financial interest in a VIE is primarily a qualitative approach focused on identifying which reporting entity has both (1) the power to direct the activities of a VIE that most significantly impact such entity’s economic performance and (2) the obligation to absorb losses or the right to receive benefits from such entity that could potentially be significant to such entity. Performance of that analysis requires the exercise of judgment. We consider a variety of factors in identifying the entity that holds the power to direct matters that most significantly impact the VIE’s economic performance including, but not limited to, the ability to direct financing, leasing, construction and other operating decisions and activities. In addition, we consider the rights of other investors to participate in those decisions, to replace the manager and to sell or liquidate the entity. We determine whether we are the primary beneficiary of a VIE at the time we become involved with a variable interest entity and reconsider that conclusion continually. We consolidate any VIE of which we are the primary beneficiary and disclose significant VIEs of which we are not the primary beneficiary, if any, as well as disclose our maximum exposure to loss related to VIEs that are not consolidated (see Note 4). Voting Interest Entities (VOEs) For VOEs, we consolidate the entity if we have a controlling financial interest. We have a controlling financial interest in a VOE if (i) for legal entities other than limited partnerships, we own a majority voting interest in the VOE or, for limited partnerships and similar entities, we own a majority of the entity’s kick-out (ii) non-controlling Other Investments Our investments in unconsolidated subsidiaries in which we have the ability to exercise significant influence over operating and financial policies, but do not control, or entities which are variable interest entities in which we are not the primary beneficiary are accounted for under the equity method. We eliminate transactions with such equity method subsidiaries to the extent of our ownership in such subsidiaries. Accordingly, our share of the earnings from these equity-method basis companies is included in consolidated net income. All other investments held on a long-term basis are valued at cost less any impairment in value. Impairment Evaluation Under either the equity or cost method, impairment losses are recognized upon evidence of other-than-temporary losses of value. When testing for impairment on investments that are not actively traded on a public market, we generally use a discounted cash flow approach to estimate the fair value of our investments and/or look to comparable activities in the marketplace. Management’s judgment is required in developing the assumptions for the discounted cash flow approach. These assumptions include net asset values, internal rates of return, discount and capitalization rates, interest rates and financing terms, rental rates, timing of leasing activity, estimates of lease terms and related concessions, etc. When determining if impairment is other-than-temporary, we also look to the length of time and the extent to which fair value has been less than cost as well as the financial condition and near-term prospects of each investment.
Use of Estimates	Use of Estimates Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S.), or GAAP, which require management to make estimates and assumptions about future events. These estimates and assumptions affect the amounts of assets, liabilities, revenue and expenses we report. Such estimates include the value of goodwill, intangibles and other long-lived 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, and are evaluated on an ongoing basis and adjusted, as needed, using historical experience and other factors, including consideration of the macroeconomic environment. As future events and their effects cannot be forecast with precision, actual results could differ significantly from these estimates. Changes in estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents generally consist of cash and highly liquid investments with an original maturity of three months or less. Included in the accompanying consolidated balance sheets as of December 31, 2016 and 2015 is cash and cash equivalents of $73.3 million and $70.2 million, respectively, from consolidated funds and other entities, which are not available for general corporate use. We also manage certain cash and cash equivalents as an agent for our investment and property and facilities management clients. These amounts are not included in the accompanying consolidated balance sheets (see Note 16).
Restricted Cash	Restricted Cash Included in the accompanying consolidated balance sheets as of December 31, 2016 and 2015 is restricted cash of $68.8 million and $72.8 million, respectively. The balances primarily include restricted cash set aside to cover funding obligations as required by contracts executed by us in the ordinary course of business.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject us to credit risk consist principally of trade receivables and interest-bearing investments. Users of real estate services account for a substantial portion of trade receivables and collateral is generally not required. The risk associated with this concentration is limited due to the large number of users and their geographic dispersion. We place substantially all of our interest-bearing investments with several major financial institutions to limit the amount of credit exposure with any one financial institution.
Property and Equipment	Property and Equipment Property and equipment, which includes leasehold improvements, is stated at cost, net of accumulated depreciation. Depreciation and amortization of property and equipment is computed primarily using the straight-line method over estimated useful lives ranging up to 10 years. Leasehold improvements are amortized over the term of their associated leases, excluding options to renew, since such leases generally do not carry prohibitive penalties for non-renewal. We review property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If this review indicates that such assets are considered to be impaired, the impairment is recognized in the period the changes occur and represents the amount by which the carrying value exceeds the fair value of the asset. Certain costs related to the development or purchase of internal-use Internal-use
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Our acquisitions require the application of purchase accounting, which results in tangible and identifiable intangible assets and liabilities of the acquired entity being recorded at fair value. The difference between the purchase price and the fair value of net assets acquired is recorded as goodwill. The majority of our goodwill balance has resulted from our acquisition of CBRE Services, Inc. (CBRE Services) in 2001 (the 2001 Acquisition), our acquisition of Insignia Financial Group, Inc. (Insignia) in 2003 (the Insignia Acquisition), our acquisition of the Trammell Crow Company in 2006 (the Trammell Crow Company Acquisition), our acquisition of substantially all of the ING Group N.V. (ING) Real Estate Investment Management (REIM) operations in Europe and Asia, as well as substantially all of Clarion Real Estate Securities (CRES) in 2011 (collectively referred to as the REIM Acquisitions), our acquisition of Norland Managed Services Ltd (Norland) in 2013 (the Norland Acquisition) and our acquisition of Johnson Controls, Inc. (JCI)’s Global Workplace Solutions (JCI-GWS) We are required to test goodwill and other intangible assets deemed to have indefinite useful lives for impairment at least annually, or more often if circumstances or events indicate a change in the impairment status. The goodwill impairment analysis is a two-step
Deferred Financing Costs	Deferred Financing Costs Costs incurred in connection with financing activities are generally deferred and amortized over the terms of the related debt agreements ranging up to ten years. Debt issuance costs related to a recognized debt liability are presented in the accompanying consolidated balance sheets as a direct deduction from the carrying amount of that debt liability. Amortization of these costs is charged to interest expense in the accompanying consolidated statements of operations. Accounting Standards Update (ASU) 2015-15, “Interest—Imputation of Interest (Subtopic 835-30): Line-of-Credit On March 21, 2016, we executed an amendment to our amended and restated credit agreement which, among other things, extended the maturity on our revolving credit facility and increased the borrowing capacity under our revolving credit facility. In connection with this amendment, we incurred approximately $5.4 million of financing costs. During 2015, we entered into an amended and restated credit agreement providing for a $500.0 million tranche A term loan facility and a $2.6 billion revolving credit facility. In addition, we added new tranche B-1 B-2 write-off During 2014, we completed three financing transactions, which included the issuance in September and December of $300.0 million and $125.0 million, respectively, in aggregate principal amount of 5.25% senior notes due March 15, 2025 and the redemption in October 2014 of all of the then outstanding 6.625% senior notes (aggregate principal amount of $350.0 million). During the year ended December 31, 2014, in connection with these financing activities, we incurred approximately $4.7 million of financing costs. In addition, we expensed $5.7 million of previously-deferred financing costs as well as a $17.4 million early extinguishment premium, all of which were included in write-off See Note 10 for additional information on activities associated with our debt.
Revenue Recognition	Revenue Recognition We record commission revenue on real estate sales generally upon close of escrow or transfer of title, except when future contingencies exist. Real estate commissions on leases are generally recorded in revenue when all obligations under the commission agreement are satisfied. Terms and conditions of a commission agreement may include, but are not limited to, execution of a signed lease agreement and future contingencies including tenant occupancy, payment of a deposit or payment of a first month’s rent (or a combination thereof). A commission agreement may provide that we earn a portion of a lease commission upon the execution of the lease agreement by the tenant and landlord, with the remaining portion(s) of the lease commission earned at a later date, usually upon tenant occupancy or payment of rent. The existence of any significant future contingencies results in the delay of recognition of corresponding revenue until such contingencies are satisfied. For example, if we do not earn all or a portion of the lease commission until the tenant pays its first month’s rent, and the lease agreement provides the tenant with a free rent period, we delay revenue recognition until rent is paid by the tenant. As some of these conditions are outside of our control and are often not clearly defined, judgment must be exercised in determining when such required events have occurred in order to recognize revenue. Property and facilities management revenues are generally based on measures consistent with the terms of the customer contracts. These contracts are negotiated utilizing a variety of terms covering various lengths of time. The fees are recognized when earned under the provisions of the related agreements. We also may earn revenue based on certain qualitative and quantitative performance measures. We recognize this revenue when the performance has been completed, the measure has been calculated and fees are deemed collectible. Our clients reimburse us for certain expenses incurred on their behalf, primarily in our property and facilities management operations. Our treatment of these reimbursements is based upon the terms of the underlying contract. We use certain indicators as to whether we record the reimbursements on a gross versus net basis, such as whether we are the primary obligor on the contracts, whether the contract is based on a fixed fee, credit risk and our discretion in making vendor selections and establishing prices. In certain instances, we have determined we are acting as the principal in the transaction and, accordingly, report these reimbursements as revenue on a gross basis with the total costs reflected in cost of services. Reimbursement revenue is recognized when the underlying reimbursable costs are incurred. When we determine we are not the primary obligor and are acting as an agent, we account for the transaction on a net basis. Investment management fees are based predominantly upon a percentage of the equity deployed on behalf of our limited partners. Fees related to our indirect investment management programs are based upon a percentage of the fair value of those investments. These fees are recognized when earned under the provisions of the related investment management agreements. Our Global Investment Management segment earns performance-based incentive fees with regard to many of its investments. Such revenue is recognized at the end of the measurement periods when the conditions of the applicable incentive fee arrangements have been satisfied and following the expiration of any potential claw back provision. With many of these investments, our Global Investment Management professionals have participation interests in such incentive fees, which are commonly referred to as carried interest. This carried interest expense is generally accrued for based upon the probability of such performance-based incentive fees being earned over the related vesting period. In addition, our Global Investment Management segment also earns success-based transaction fees with regard to buying or selling properties on behalf of certain funds and separate accounts. Such revenue is recognized at the completion of a successful transaction and is not subject to any claw back provision. Appraisal fees are recorded after services have been rendered. Loan origination fees are recognized at the time a loan closes and we have no significant remaining obligations for performance in connection with the transaction, while loan servicing fees are recorded in revenue as monthly principal and interest payments are collected from mortgagors. Other commissions, consulting fees and referral fees are recorded as revenue at the time the related services have been performed, unless future contingencies exist. Development services and project management services generate fees from development and construction management projects. Most development and construction management and project management assignments are subject to agreements that describe the calculation of fees and when we earn such fees. The earnings terms of these agreements dictate when we recognize the related revenue. Generally, development fees are recognized based on the lower of the amount billed or the amount determined on a straight-line basis over the development period. We may earn incentive fees for project management services based upon achievement of certain performance criteria as set forth in the project management services agreement. Incentive development fees are recognized when quantitative criteria have been met (such as specified leasing, budget or time-based targets) or for those incentive fees based on qualitative criteria, upon approval of the fee by our clients. Certain incentive development fees allow us to share in the fair value of the developed real estate asset above cost. This sharing creates additional revenue potential to us with no exposure to loss other than opportunity cost. We recognize such fees when the specified target is attained and fees are deemed collectible. We record deferred income to the extent that cash payments have been received in accordance with the terms of underlying agreements, but such amounts have not yet met the criteria for revenue recognition in accordance with generally accepted accounting principles. We recognize such revenues when the appropriate criteria are met. In establishing the appropriate provisions for trade receivables, we make assumptions with respect to future collectability. Our assumptions are based on an assessment of a customer’s credit quality as well as subjective factors and trends, including the aging of receivables balances. In addition to these assessments, in general, outstanding trade accounts receivable amounts that are more than 180 days overdue are evaluated for collectability and fully provided for if deemed uncollectible. Historically, our credit losses have generally been insignificant. However, estimating losses requires significant judgment, and conditions may change or new information may become known after any periodic evaluation. As a result, actual credit losses may differ from our estimates.
Business Promotion and Advertising Costs	Business Promotion and Advertising Costs The costs of business promotion and advertising are expensed as incurred. Business promotion and advertising costs of $65.8 million, $62.7 million and $55.6 million were included in operating, administrative and other expenses for the years ended December 31, 2016, 2015 and 2014, respectively.
Foreign Currencies	Foreign Currencies The financial statements of subsidiaries located outside the U.S. are generally measured using the local currency as the functional currency. The assets and liabilities of these subsidiaries are translated at the rates of exchange at the balance sheet date, and income and expenses are translated at the average monthly rate. The resulting translation adjustments are included in the accumulated other comprehensive loss component of equity. Gains and losses resulting from foreign currency transactions are included in the results of operations.
Derivative Financial Instruments and Hedging Activities	Derivative Financial Instruments and Hedging Activities As required by FASB ASC Topic 815 “ Derivatives and Hedging
Comprehensive Income	Comprehensive Income Comprehensive income consists of net income and other comprehensive loss. In the accompanying consolidated balance sheets, accumulated other comprehensive loss consists of foreign currency translation adjustments, fees associated with the termination of interest rate swaps, unrealized losses on interest rate swaps, unrealized holding gains (losses) on available for sale securities and pension liability adjustments. Foreign currency translation adjustments exclude any income tax effect given that earnings of non-U.S.
Marketable Securities	Marketable Securities We account for investments in marketable debt and equity securities in accordance with the “ Investments – Debt and Equity Securities Trading securities are carried at their fair value with realized and unrealized gains and losses included in net income. Available for sale securities are carried at their fair value and any difference between cost and fair value is recorded as unrealized gain or loss, net of income taxes, and is reported as accumulated other comprehensive loss in the consolidated statement of equity. Premiums and discounts are recognized in interest using the effective interest method. Realized gains and losses and declines in value expected to be other-than-temporary on available for sale securities have not been significant. The cost of securities sold is based on the specific identification method. Interest and dividends on securities classified as available for sale are included in interest income. For investments classified as available for sale, we assess impairment at the individual security level. An investment is impaired if the fair value of the investment is less than its amortized cost basis. When an impairment exists, we assess whether such impairment is temporary or other-than-temporary. We review the volatility and intended holding period of our investments and also determine if we believe that there is a reasonable possibility that the value would be recovered over the intended holding period. Based on our review, we did not record any significant other-than-temporary impairment losses during the years ending December 31, 2016, 2015 and 2014.
Warehouse Receivables	Warehouse Receivables 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 is a U.S. Department of Housing and Urban Development (HUD) approved Non-Supervised one-month
Mortgage Servicing Rights	Mortgage Servicing Rights In connection with the origination and sale of mortgage loans with servicing rights retained, we record servicing assets or liabilities based on the fair value of the mortgage servicing rights on the date the loans are sold. We also assume or purchase certain servicing assets. Our mortgage service rights (MSRs) are initially recorded at fair value. Subsequent to the initial recording, MSRs are amortized and carried at the lower of amortized cost or fair value in other intangible assets in the accompanying consolidated balance sheets. They are amortized in proportion to and over the estimated period that net servicing income is expected to be received based on projections and timing of estimated future net cash flows. Our initial recording of MSRs at their fair value resulted in net gains, as the fair value of servicing contracts that result in MSR assets exceeded the fair value of servicing contracts that result in MSR liabilities. The net assets and net gains are presented in the accompanying consolidated financial statements. The amount of MSRs recognized during the years ended December 31, 2016 and 2015 was as follows (dollars in thousands): Year Ended December 31, 2016 2015 Beginning balance, mortgage servicing rights $ 244,723 $ 202,982 Mortgage servicing rights recognized 154,040 110,428 Mortgage servicing rights sold (790 ) (783 ) Amortization expense (73,273 ) (59,608 ) Other (4,176 ) (8,296 ) Ending balance, mortgage servicing rights $ 320,524 $ 244,723 Mortgage servicing rights do not actively trade in an open market with readily available observable prices; therefore, fair value is determined based on certain assumptions and judgments, including the estimation of the present value of future cash flows realized from servicing the underlying mortgage loans. Management’s assumptions include the benefits of servicing (servicing fee income and interest on escrow deposits), inflation, the cost of servicing, prepayment rates, delinquencies, discount rates and the estimated life of servicing cash flows. The assumptions used are subject to change based on management’s judgments and estimates of changes in future cash flows and interest rates, among other things. The key assumptions used during the years ended December 31, 2016, 2015 and 2014 in measuring fair value were as follows: Year Ended December 31, 2016 2015 2014 Discount rate 10.16 % 10.11 % 10.38 % Conditional prepayment rate 9.66 % 6.03 % 6.14 % The estimated fair value of our mortgage servicing rights was $375.5 million and $301.2 million as of December 31, 2016 and 2015, respectively. Impairment is evaluated through a comparison of the carrying amount and fair value of the MSRs, and recognized with the establishment of a valuation allowance. We did not incur any impairment charges related to our MRSs during the years ended December 31, 2016, 2015 or 2014. No valuation allowance was created previously and we did not record a valuation allowance for MSRs in 2016 or 2015. Included in revenue in the accompanying consolidated statements of operations are contractually specified servicing fees from loans serviced for others of $104.2 million, $78.9 million and $65.2 million for the years ended December 31, 2016, 2015 and 2014, respectively, and prepayment fees/late fees/ancillary income earned from loans serviced for others of $7.2 million, $8.4 million and $6.1 million for the years ended December 31, 2016, 2015 and 2014, respectively.
Accounting for Broker Draws	Accounting for Broker Draws As part of our recruitment efforts relative to new U.S. brokers, we offer a transitional broker draw arrangement. Our broker draw arrangements generally last until such time as a broker’s pipeline of business is sufficient to allow him or her to earn sustainable commissions. This program is intended to provide the broker with a minimal amount of cash flow to allow adequate time for his or her training as well as time for him or her to develop business relationships. Similar to traditional salaries, the broker draws are paid irrespective of the actual revenues generated by the broker. Often these broker draws represent the only form of compensation received by the broker. Furthermore, it is not our general policy to pursue collection of unearned broker draws paid under this arrangement. As a result, we have concluded that broker draws are economically equivalent to salaries paid and accordingly charge them to compensation expense as incurred. The broker is also entitled to earn a commission on completed revenue transactions. This amount is calculated as the commission that would have been payable under our full commission program, less any amounts previously paid to the broker in the form of a draw.
Stock-Based Compensation	Stock-Based Compensation We account for all employee awards under the fair value recognition provisions of the “ Compensation – Stock Compensation In the third quarter of 2016, we elected to early adopt the provisions of ASU 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting,” 2016-09 paid-in 2016-09 See Note 12 for additional information on our stock-based compensation plans.
Income Per Share	Income Per Share Basic income per share attributable to CBRE Group, Inc. is computed by dividing net income attributable to CBRE Group, Inc. shareholders by the weighted average number of common shares outstanding during each period. The computation of diluted income per share attributable to CBRE Group, Inc. generally further assumes the dilutive effect of potential common shares, which include stock options and certain contingently issuable shares. Contingently issuable shares consist of non-vested
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method in accordance with the “ Accounting for Income Taxes
Self-Insurance	Self-Insurance Our wholly-owned captive insurance company, which is subject to applicable insurance rules and regulations, insures our exposure related to workers’ compensation insurance, general liability insurance and automotive insurance for our U.S. operations risk on a primary basis and we purchase excess coverage from unrelated insurance carriers. The captive insurance company also insures primary risk relating to professional indemnity claims globally. Given the nature of these types of claims, it may take several years for resolution and determination of the cost of these claims. We are required to estimate the cost of these claims in our financial statements. The estimates that we utilize to record our potential losses on claims are inherently subjective, and actual claims could differ from amounts recorded, which could result in increased or decreased expense in future periods. As of December 31, 2016 and 2015, our reserves for claims under these insurance programs were $80.6 million and $73.8 million, respectively, of which $1.7 million and $1.9 million, respectively, represented our estimated current liabilities.
New Accounting Pronouncements	New Accounting Pronouncements Recent Accounting Pronouncements Pending Adoption The FASB has recently issued five ASUs related to revenue recognition (“new revenue recognition guidance”), all of which become effective for the company on January 1, 2018. The ASUs issued are: (1) in May 2014, ASU 2014-09, “Revenue from Contracts with Customers (Topic 606);” ASU 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net);” 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing;” 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-scope Improvements and Practical Expedients;” 2016-20, “Technical Corrections and Improvements to Topic 606, Revenue From Contracts with Customers.” 2014-09 2016-08 2016-10 2014-09. 2016-12 2016-20 We plan to adopt the new revenue recognition guidance in the first quarter of 2018 and are evaluating the application of a transition method. We continue to evaluate the impact that adoption of these updates will have on our consolidated financial statements. Based on our initial assessment, the impact of the application of the new revenue recognition guidance will likely result in an acceleration of some revenues that are based, in part, on future contingent events.

Reclassifications	Reclassifications Certain reclassifications have been made to the 2015 and 2014 financial statements to conform with the 2016 presentation.
Fair Value Measurements and Disclosures	The “Fair Value Measurements and Disclosures” • 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.
Valuation of Interest Rate Swaps and Foreign Currency Exchange Forward Contracts	The valuation of interest rate swaps and foreign currency exchange forward contracts is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate and foreign currency exchange forward curves. The fair values of interest rate swaps and foreign currency exchange forward contracts are determined using the market standard methodology of netting the discounted future estimated cash payments/receipts. The estimated cash flows are based on an expectation of future interest rates or foreign currency exchange rates using forward curves derived from observable market interest rate and foreign currency exchange forward curves.

Debt instrument redemption description

The 4.875% senior notes are redeemable at our option, in whole or in part, prior to December 1, 2025 at a redemption price equal to the greater of (1) 100% of the principal amount of the 4.875% senior notes to be redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest thereon to December 1, 2025 (not including any portions of payments of interest accrued as of the date of redemption) discounted to the date of redemption on a semi-annual basis at the Adjusted Treasury Rate (as defined in the indenture governing these notes). In addition, at any time on or after December 1, 2025, the 4.875% senior notes may be redeemed by us, in whole or in part, at a redemption price equal to 100.0% of the principal amount, plus accrued and unpaid interest, if any, to (but excluding) the date of redemption. If a change of control triggering event (as defined in the indenture governing these notes) occurs, we are obligated to make an offer to purchase the then outstanding 4.875% senior notes at a redemption price of 101.0% of the principal amount, plus accrued and unpaid interest, if any, to the date of purchase.
