Non-GAAP Financial Measures The following measures are considered “non-GAAP financial measures” under SEC guidelines: fee revenue contractual fee revenue net income attributable to CBRE Group, Inc., as adjusted (which we also refer to as “adjusted net income”) diluted income per share attributable to CBRE Group, Inc. shareholders, as adjusted (which we also refer to as “adjusted earnings per share” or “adjusted EPS”) EBITDA and adjusted EBITDA None of these measures is a recognized measurement under United States generally accepted accounting principles, or “GAAP,” and when analyzing our operating performance, readers should use them in addition to, and not as an alternative for, their most directly comparable financial measure calculated and presented in accordance with GAAP. Because not all companies use identical calculations, our presentation of these measures may not be comparable to similarly titled measures of other companies.  Our management generally uses these non-GAAP financial measures to evaluate operating performance and for other discretionary purposes, and the company believes that these measures provide a more complete understanding of ongoing operations, enhance comparability of current results to prior periods and may be useful for investors to analyze our financial performance because they eliminate the impact of selected charges that may obscure trends in the underlying performance of our business. The company further uses certain of these measures, and believes that they are useful to investors, for purposes described below.  With respect to fee revenue: the company believes that investors may find this measure useful to analyze the financial performance of our Occupier Outsourcing and Property Management business lines and our business generally because it excludes costs reimbursable by clients, and as such provides greater visibility into the underlying performance of our business.  With respect to contractual fee revenue: the company believes that investors may find this measure useful to analyze our overall financial performance because it identifies revenue streams that are typically more stable over time.  With respect to adjusted net income, adjusted EPS, EBITDA and adjusted EBITDA: the company believes that investors may find these measures useful in evaluating our operating performance compared to that of other companies in our industry because these calculations generally eliminate the accounting effects of acquisitions, which would include impairment charges of goodwill and intangibles created from acquisitions—and in the case of EBITDA and adjusted EBITDA—the effects of financings and income tax and the accounting effects of capital spending. All of these measures may vary for different companies for reasons unrelated to overall operating performance. In the case of EBITDA and adjusted EBITDA, these measures are not intended to be measures of free cash flow for our management’s discretionary use because they do not consider cash requirements such as tax and debt service payments. The EBITDA and adjusted EBITDA measures calculated herein may also differ from the amounts calculated under similarly titled definitions in our credit facilities and debt instruments, which amounts are further adjusted to reflect certain other cash and non-cash charges and are used by us to determine compliance with financial covenants therein and our ability to engage in certain activities, such as incurring additional debt and making certain restricted payments. The company also uses adjusted EBITDA and adjusted EPS as significant components when measuring our operating performance under our employee incentive compensation programs.

Footnotes Slide 6 Adjusted EBITDA excludes (from EBITDA) certain carried interest incentive compensation expense (reversal) to align with the timing of associated revenue, cost elimination expenses and integration and other costs related to acquisitions. Adjusted EPS excludes amortization expense related to certain intangible assets attributable to acquisitions, the write-off of financing costs on extinguished debt, cost elimination expenses, integration and other costs related to acquisitions, and adjusts certain carried interest incentive compensation expense (reversal) to align with the timing of associated revenue, as well as adjusts the provision for income taxes for such charges. NOTE: Local currency percent changes versus prior year are non-GAAP financial measures noted on slide 11. These percent changes are calculated by comparing current year results versus prior year results, in each case at prior year exchange rates. Slide 3 Assets Under Management (AUM) as of December 31, 2016. As of December 31, 2016, includes affiliates. Property and Corporate Facilities under Management as of December 31, 2015; 7% of this square footage is managed by affiliates. Slide 7 and 19 We regard leasing revenue as largely recurring over time because unlike most other transaction businesses, leasing activity normally takes place when leases expire. The average lease expires in five to six years. This means that, on average, in a typical year approximately 17% to 20% of leases roll over and a new leasing decision must be made. When a lease expires in the ordinary course, we expect it to be renewed, extended or the tenant to vacate the space to lease another space in the market.   In each instance, a transaction is completed.  If there is a downturn in economic activity, some tenants may seek a short term lease extension, often a year, before making a longer term commitment. In this scenario, that delayed leasing activity tends to be stacked on top of the normal activity in the following year. Thus, we characterize leasing as largely recurring over time because we expect an expiration of a lease, in the ordinary course, to lead to an opportunity for a leasing commission from such completed transaction. Slide 10 Other includes Development Services revenue (1% in both 2006 and 2016) and Other revenue (1% in both 2006 and 2016). Capital Markets includes Sales revenue (33% in 2006 and 19% in 2016) and Commercial Mortgage Services revenue (4% in 2006 and 6% in 2016). Contractual Sources include Occupier Outsourcing and Property Management revenue (7% in 2006 and 32% in 2016; excludes associated sales and lease revenues, most of which are contractual), Global Investment Management revenue (6% in 2006 and 4% in 2016), and Valuation revenue (8% in 2006 and 6% in 2016). Fee Revenue is gross revenue less client reimbursed costs largely associated with our employees that are dedicated to client facilities and subcontracted vendor work performed for clients. Contractual plus leasing revenues are 64% of 2006 GAAP revenue and 81% of 2016 GAAP revenue.

Footnotes Slide 17 Excludes global securities business. As of December 31, 2016. Slide 24 As of December 31 for each year presented In Process figures include Long-Term Operating Assets (LTOA) of $0.2 billion for Q4 2016, $0.1 billion for Q4 2015, $0.3 billion for Q4 2014, $0.9 billion for Q4 2013 and $1.2 billion for Q4 2012. LTOA are projects that have achieved a stabilized level of occupancy or have been held 18-24 months following shell completion or acquisition. Pipeline deals are those projects we are pursuing which we believe have a greater than 50% chance of closing or where land has been acquired and the projected construction start is more than twelve months out. Slide 15 Historical revenue for Occupier Outsourcing line of business (formerly Global Corporate Services or GCS, now called Global Workplace Solutions) excludes associated sales and leasing revenue, most of which is contractual. 2015 revenue includes four months of contribution from the Global Workplace Solutions business acquired on September 1, 2015. Per International Association of Outsourcing Professionals (IAOP). Slide 16 Property Management (also known as Asset Services) revenue excludes associated sales and leasing revenue, most of which is contractual. 13% of this square footage is managed by affiliates. Slide 23 Activity includes loan originations and loan sales, and affiliate loan originations. As measured in dollar value loaned. Slide 11 Contractual revenue refers to revenue derived from our Occupier Outsourcing, Property Management, Investment Management and Valuation businesses. We regard leasing revenue as largely recurring over time because unlike most other transaction businesses, leasing activity normally takes place when leases expire. The average lease expires in five to six years. This means that, on average, in a typical year approximately 17% to 20% of leases roll over and a new leasing decision must be made. When a lease expires in the ordinary course, we expect it to be renewed, extended or the tenant to vacate the space to lease another space in the market.   In each instance, a transaction is completed.  If there is a downturn in economic activity, some tenants may seek a short term lease extension, often a year, before making a longer term commitment. In this scenario, that delayed leasing activity tends to be stacked on top of the normal activity in the following year. Thus, we characterize leasing as largely recurring over time because we expect an expiration of a lease, in the ordinary course, to lead to an opportunity for a leasing commission from such completed transaction. Occupier Outsourcing and Property Management revenue excludes associated leasing and sales revenue, most of which is contractual. Fee revenue is gross revenue less both client reimbursed costs largely associated with employees that are dedicated to client facilities and subcontracted vendor work performed for clients.
