Competition

We compete across a variety of business disciplineslines within the commercial real estate industry, including commercial property, corporate facilities, project and transaction management, tenant/occupier and property/agency leasing, propertycapital markets solutions (property sales, valuation, real estate investment management, commercial mortgage origination, sales and servicing, capital markets (structuredand structured finance) solutions,real estate investment management, valuation, development services and proprietary research. Each business disciplineline is highly competitive on an international, national, regional and local level. Although we are the largest commercial real estate services firm in the world in terms of 20152016 revenue, our relative competitive position varies significantly across geographic markets, property types and services. We face competition from other commercial real estate service providers that compete with us on a global, national, regional or local basis or within a market segment; outsourcing companies that traditionally competed in limited portions of our facilities management business and have expanded their offerings from time to time;in-house corporate real estate departments and property owners/developers that self-perform real estate services; investment banking firms, investment managers and developers that compete with us to raise and place investment capital; and accounting/consulting firms that advise on real estate strategies. Some of these firms may have greater financial resources than we do.

Despite recent consolidation, the commercial real estate services industry remains highly fragmented and competitive. Although many of our competitors are substantially smaller than us,we are, some of them are larger on a regional or local basis or have a stronger position in a specific market segment or service offering. Among our

primary competitors are other large national and global firms, such as Cushman & Wakefield, (which is the name adopted following the combination of DTZ and Cushman & Wakefield),JLL (formerly Jones Lang LaSalle Incorporated,Incorporated), Colliers International Group Inc. (which was spun off from FirstService Corporation in 2015), Savills plc (which acquired U.S.-based service provider Studley, Inc. in 2014) and BGC Partners (which is the publicly traded

parent of Newmark Grubb Knight Frank); market-segment specialists, such as Eastdil Secured, HFF, L.P. and, Marcus & Millichap, Inc. and Walker & Dunlop, Inc.; and firms with business lines that compete with our occupier outsourcing business.

Seasonality

A significant portion of our revenue is seasonal, which an investor should keep in mind when comparing our financial condition and results of operations on aquarter-by-quarter basis. Historically, our revenue, operating income, net income and cash flow from operating activities tend to be lowest in the first calendar quarter, and highest in the fourth calendar quarter of each year. EarningsRevenue, earnings and cash flow have generally been concentrated in the fourth calendar quarter due to the focus on completing sales, financing and leasing transactions prior to calendar year-end.

Employees

At December 31, 2015,2016, excluding our independent affiliates, we had more than 70,00075,000 employees worldwide, approximately 37% of which representwhose costs that are fully reimbursed by clients and are mostly in our outsourcing servicesGlobal Workplace Solutions and Asset Services lines of business. At December 31, 2015,2016, approximately 1,9001,800 of our employees were subject to collective bargaining agreements, most of whom are on-site employeeswork in our asset services businessproperties we manage in California, Illinois, New Jersey and New York.

Intellectual Property

We hold various trademarks and trade names worldwide, which include the “CBRE” name. Although we believe our intellectual property plays a role in maintaining our competitive position in a number of the markets that we serve, we do not believe we would be materially, adversely affected by expiration or termination of our trademarks or trade names or the loss of any of our other intellectual property rights other than the “CBRE” and “Trammell Crow Company” names. We maintain trademark registrations for the CBRE service mark in jurisdictions where we conduct significant business.

We hold a license to use the “Trammell Crow Company” trade name pursuant to a license agreement with CF98, L.P., an affiliate of Crow Realty Investors, L.P., d/b/a Crow Holdings, which may be revoked if we fail to satisfy usage and quality control covenants under the license agreement.

Environmental Matters

Federal, state and local laws and regulations in the countries in which we do business impose environmental liabilities, controls, disclosure rules and zoning restrictions that affect the ownership, management, development, use or sale of commercial real estate. Certain of these laws and regulations may impose liability on current or previous real property owners or operators for the cost of investigating, cleaning up or removing contamination caused by hazardous or toxic substances at a property, including contamination resulting from above-ground or underground storage tanks or the presence of asbestos or lead at a property. If contamination occurs or is present during our role as a property or facility manager or developer, we could be held liable for such costs as a current “operator” of a property, regardless of the legality of the acts or omissions that caused the contamination and

without regard to whether we knew of, or were responsible for, the presence of such hazardous or toxic substances. The operator of a site also may be liable under common law to third parties for damages and injuries resulting from exposure to hazardous substances or environmental contamination at a site, including liabilities arising from exposure to asbestos-containing materials. Under certain laws and common law principles, any failure by us to disclose environmental contamination at a property could subject us to liability to a buyer or lessee of the property. Further, federal, state and local governments in the countries in which we do business have enacted various laws, regulations and treaties governing environmental and climate change, particularly for “greenhouse gases,” which seek to tax, penalize or limit their release. Such regulations could lead to increased operational or compliance costs over time.

While we are aware of the presence or the potential presence of regulated substances in the soil or groundwater at or near several properties owned, operated or managed by us that may have resulted from historical or ongoing activities on those properties, we are not aware of any material noncompliance with the environmental laws or regulations currently applicable to us, and we are not the subject of any material claim for liability with respect to contamination at any location. However, these laws and regulations may discourage sales and leasing activities and mortgage lending with respect to some properties, which may adversely affect both the commercial real estate services industry in general and us in general.us. Environmental contamination or other environmental liabilities may also negatively affect the value of commercial real estate assets held by entities that are managed by our investment management and development services businesses, which could adversely affect the results of operations of these business lines.

Our business is significantly affected by generally prevailing economic conditions in the markets where we principally operate, which can result in a general decline in real estate acquisition, disposition and leasing activity, as well as a general decline in the value of commercial real estate and in rents, which in turn reduces revenue from asset services fees and commissions derived from property sales, leasing, valuation and financing, as well as revenues associated with development or investment management activities. Our businesses could also suffer from any political or economic disruptiondisruptions that affectsaffect interest rates or liquidity.liquidity or create financial, market or regulatory uncertainty. For example, the U.K.’s vote to withdraw from the European Union, commonly known as “Brexit,” and speculation about the terms and consequences of this exit or that of other European Union members has caused and may continue to cause market volatility and currency fluctuations and adversely impact our clients’ confidence, which may result in a deterioration in our U.K. and other European businesses as leasing and investing activity slow down.

Adverse economic conditions or political or regulatory uncertainty could also lead to a decline in property sales prices as well as a decline in funds invested in existing commercial real estate assets and properties planned for development, which in turn could reduce the commissions and fees that we earn. In addition, our development and investment strategy often entails makingco-investments alongside our investor clients. During an economic downturn, capital for our investment activities is usually constrained and it may take longer for us to dispose of real estate investments or selling prices may be lower than originally anticipated. As a result, the value of our commercial real estate investments may be reduced, and we could realize losses or diminished profitability. In addition, economic downturns may reduce the amount of loan originations and related servicing by our Capital Markets business.

The performance of our asset services line of business depends upon how well the properties we manage perform. This is because our fees are generally based on a percentage of rent collections from these properties. Rent collections may be affected by many factors, including: (i) real estate and financial market conditions prevailing generally and locally; (ii) our ability to attract and retain creditworthy tenants, particularly during economic downturns; and (iii) the magnitude of defaults by tenants under their respective leases, which may increase during distressed economic conditions.

Certain geographies within the Americas, as well as certain industry sectors that we serve, have been negatively affected by the recent weakened performance of the oil and gas industry, which may in turn diminish the performance of our various businesses in those geographies as well as reduce the demand for our services by our clients in such areas or who are affected by that industry. In continental Europe and Asia Pacific, the economic recovery is slow and fragile. If recoveryeconomies in certain European economies stalls, our performance maycountries can be adversely affected. In addition, China’s deteriorating macro-economic environment could adversely affect our operations in our Asia Pacific segment,fragile, which may adversely affect our financial performance.

Economic, political and regulatory uncertainty as well as significant changes and volatility in the financial markets and business environment, and in the global landscape, make it increasingly difficult for us to predict our financial performance into the future. As a result, any guidance or outlook that we provide on our performance is based on then-current conditions, and there is a risk that such guidance may turn out to be inaccurate.

Adverse developments in the credit markets may harm our business, results of operations and financial condition.

Our Global Investment Management, Development Services and Capital Markets (including investment property sales and debtmortgage and structured financing services) businesses are sensitive to credit cost and availability

as well as marketplace liquidity. Additionally, the revenues in all of our businesses are dependent to some extent on the overall volume of activity (and pricing) in the commercial real estate market.

Disruptions in the credit markets may adversely affect our business of providing advisory services to owners, investors and occupiers of real estate in connection with the leasing, disposition and acquisition of property. If our clients are unable to procure credit on favorable terms, there may be fewer completed leasing transactions, dispositions and acquisitions of property. In addition, if purchasers of commercial real estate are not able to procure favorable financing resulting in the lack of disposition opportunities for our funds and projects, our Global Investment Management and Development Services businesses may be unable to generate incentive fees, and we may also experience losses ofco-invested equity capital if the disruption causes a permanent decline in the value of investments made.

Our operations are subject to social, political and economic risks in foreign countries as well as foreign currency volatility.

We conduct a significant portion of our business and employ a substantial number of people outside of the United States and as a result, we are subject to risks associated with doing business globally. During 2015,2016, approximately 45%47% of our revenue was transacted in foreign currencies, the majority of which included the Australian dollar, Brazilian real, British pound sterling, Canadian dollar, Chinese yuan, Danish krone, euro, Hong Kong dollar, Indian rupee, Japanese yen, Mexican peso, Polish zloty, Singapore dollar, Swedish krona, Swiss franc and Swiss franc.Thai baht. Fluctuations in foreign currency exchange rates may result in corresponding fluctuations in our assets under management for our Global Investment Management business, revenue and earnings. Over time, fluctuations in the value of the U.S. dollar relative to the other currencies in which we may generate earnings could adversely affect our business, financial condition and operating results. Due to the constantly changing currency exposures to which we are subject and the volatility of currency exchange rates, we cannot predict the effect of exchange rate fluctuations upon future operating results. For example, Brexit caused a significant decline in the value of the British pound sterling against the U.S. dollar during 2016 and negotiations with respect to the terms of the U.K.’s withdrawal or other changes to the membership or policies of the European Union, or speculation about such events, may cause additional volatility in international currency markets. In addition, fluctuations in currencies relative to the U.S. dollar may make it more difficult to performperiod-to-period comparisons of our reported results of operations.

Additional circumstances and developments related to international operations that could negatively affect our business, financial condition or results of operations include, but are not limited to, the following factors:

We maintain anti-corruption and anti-money-laundering compliance programs and programs designed to enable us to comply with applicable government economic sanctions, embargoes and other import/export controls throughout the company. But, coordinating our activities to deal with the broad range of complex legal and regulatory environments in which we operate presents significant challenges. We may not be successful in complying with regulations in all situations and violations may result in criminal or civil sanctions, including material monetary fines, penalties, equitable remedies (including disgorgement), and other costs against us or our employees, and may have a material adverse effect on our reputation and business.

We have committed additional resources to expand our worldwide sales and marketing activities, to globalize our service offerings and products in selectedselect markets and to develop local sales and support channels. If we are unable to successfully implement these plans, maintain adequate long-term strategies that successfully manage the risks associated with our global business or adequately manage operational fluctuations, our business, financial condition or results of operations could be harmed. In addition, we have penetrated, and seek to continue to enter into, emerging markets to further expand our global platform. However, we may not be successful in effectively evaluating and monitoring the key business, operational, legal and compliance risks specific to those markets. The political and cultural risks present in emerging countries could also harm our ability to successfully execute our operations or manage our businesses there.

Our success depends upon the retention of our senior management, as well as our ability to attract and retain qualified and experienced employees.

Our continued success is highly dependent upon the efforts of our executive officers and other key employees, including Robert E. Sulentic, our President and Chief Executive Officer. Mr. Sulentic and certain other key employees are not parties to employment agreements with us. We also are highly dependent upon the retention of our property sales and leasing professionals, who generate a significant amount of our revenues, as well as other revenue producing professionals. The departure of any of our key employees, or the loss of a significant number of key revenue producers, if we are unable to quickly hire and integrate qualified replacements, could cause our business, financial condition and results of operations to suffer. Competition for these personnel is significant and we may not be able to successfully recruit, integrate or retain sufficiently qualified personnel. In addition, the growth of our business is largely dependent upon our ability to attract and retain qualified support personnel in all areas of our business. We and our competitors use equity incentives andsign-on and retention bonuses to help attract, retain and incentivize key personnel. As competition is significant for the services of such personnel, the expense of such incentives and bonuses may increase and we may be unable to attract or retain such personnel to the same extent that we have in the past. Any significant decline in, or failure to grow, our stock price may result in an increased risk of loss of these key personnel. Furthermore, shareholder influence on our compensation practices, including our ability to issue equity compensation, may decrease our ability to offer attractive compensation to key personnel and make recruiting, retaining and incentivizing such personnel more difficult. If we are unable to attract and retain these qualified personnel, our growth may be limited and our business and operating results could suffer.

We have numerous local and global competitors across all of our business lines and the geographies that we serve, and further industry consolidation could lead to significant future competition.

We compete across a variety of business disciplines within the commercial real estate services and investment industry, including commercial property, corporate facilities, project and transaction management, tenant/occupier and property/agency leasing, capital markets solutions (property sales, commercial mortgage brokerage, loan origination and servicing), real estate investment management, valuation, development services and proprietary research. Although we are the largest commercial real estate services firm in the world in terms of 2016 revenue, our relative competitive position varies significantly across geographies, property types and services and business lines. Depending on the geography, property type or service or business line, we face competition from other commercial real estate service providers and investment firms, including outsourcing companies that traditionally competed in limited portions of our facilities management business and have expanded their offerings from time to time,in-house corporate real estate departments, developers, institutional lenders, insurance companies, investment banking firms, investment managers and accounting and consulting firms. Some of these firms may have greater financial resources allocated to a particular geography, property type or service or business line than we have allocated to that geography, property type, service or business line. In addition, future changes in laws could lead to the entry of other new competitors, such as financial institutions. Although many of our existing competitors are local or regional firms that are smaller than we are, some of these competitors are larger on a local or regional basis. We are further subject to competition from large national and multi-national firms that have similar service and investment competencies to ours, and it is possible that further industry consolidation could lead to much larger and more formidable competitors globally or in the particular geographies, property types, service or business lines that we serve. There is no assurance that we will be able to compete effectively, to maintain current fee levels or margins, or maintain or increase our market share.

Our growth has benefited significantly from acquisitions, which may not perform as expected and similar opportunities may not be available in the future.

A significant component of our growth over time has been generated by acquisitions. Any future growth through acquisitions will depend in part upon the continued availability of suitable acquisition candidates at favorable prices and upon advantageous terms and conditions, which may not be available to us, as well as sufficient liquidity and credit to fund these acquisitions. We may incur significant additional debt from time to time to finance any such acquisitions, subject to the restrictions contained in the documents governing our then-existing indebtedness. If we incur additional debt, the risks associated with our leverage, including our ability to service our then-existing debt, would increase. Acquisitions involve risks that business judgments concerning the value, strengths and weaknesses of businesses acquired may prove incorrect. Future acquisitions and any necessary related financings also may involve significant transaction-related expenses, which include severance, lease termination, transaction and deferred financing costs, among others.

We have had, and may continue to experience, challenges in integrating operations and information technology systems acquired from other companies. This could result in the diversion of management’s attention from other business concerns and the potential loss of our key employees or clients or those of the acquired operations. The integration process itself may be disruptive to our business and the acquired company’s businesses as it requires coordination of geographically diverse organizations and implementation of new accounting and information technology systems. We believe that most acquisitions will initially have an adverse impact on operating and net income. Acquisitions also frequently involve significant costs related to integrating information technology and accounting and management services and rationalizing personnel levels.services.

We complete acquisitions with the expectation that they will result in various benefits, including enhanced or more stable revenues, a strengthened market position, cross-selling opportunities, cost synergies, tax benefits and accretion to our adjusted income per share. Achieving the anticipated benefits of these acquisitions is subject to a number of uncertainties, including the realization of accretive benefits in the timeframe anticipated and whether we can successfully integrate the acquired business. Failure to achieve these anticipated benefits could

result in increased costs, decreases in the amount of expected revenues and diversion of management’s time and energy, which could in turn materially and adversely affect our overall business, financial condition and operating results.

Our success depends upon the retention of our senior management, as well as our ability to attract and retain qualified and experienced employees.

Our continued success is highly dependent upon the efforts of our executive officers and other key employees, including Robert E. Sulentic, our President and Chief Executive Officer. Mr. Sulentic and certain other key employees are not parties to employment agreements with us. We also are highly dependent upon the retention of our property sales and leasing professionals, who generate a significant amount of our revenues, as well as other revenue producing professionals. The departure of any of our key employees, or the loss of a significant number of key revenue producers, if we are unable to quickly hire and integrate qualified replacements, could cause our business, financial condition and results of operations to suffer. Competition for these personnel is significant and we may not be able to successfully recruit, integrate or retain sufficiently qualified personnel. In addition, the growth of our business is largely dependent upon our ability to attract and retain qualified support personnel in all areas of our business. We and our competitors use equity incentives and sign-on and retention bonuses to help attract, retain and incentivize key personnel. As competition is significant for the services of such personnel, the expense of such incentives and bonuses may increase and we may be unable to attract or retain such personnel to the same extent that we have in the past. Any significant decline in, or failure to grow, our stock price may result in an increased risk of loss of these key personnel. If we are unable to attract and retain these qualified personnel, our growth may be limited and our business and operating results could suffer.

Our joint venture activities and affiliate program involve unique risks that are often outside of our control and that, if realized, could harm our business.

We have utilized joint ventures for commercial investments, select local brokerage and other affiliations both in the United States and internationally, and we may acquire interests in other joint ventures in the future. Under our affiliate program, we enter into contractual relationships with local brokerage, asset services or other operations pursuant to which we license to that operation our name and make available certain of our resources, in exchange for a royalty or economic participation in that operation’s revenue, profits or transactional activity. In many of these joint ventures and affiliations, we may not have the right or power to direct the management and policies of the joint ventures or affiliates, and other participants or operators of affiliates may take action contrary to our instructions or requests and against our policies and objectives. In addition, the other participants and operators may become bankrupt or have economic or other business interests or goals that are inconsistent with ours. If a joint venture participant or affiliate acts contrary to our interest, it could harm our brand, business, results of operations and financial condition.

Our real estate investment andco-investment activities in our Global Investment Management as well as Development Services businesses subject us to real estate investment risks which could cause fluctuations in earnings and cash flow.

An important part of the strategy for our Global Investment Management business involvesco-investing our capital in certain real estate investments with our clients, and there is an inherent risk of loss of our investments. As of December 31, 2015,2016, we had committed $12.8$31.6 million to fund futureco-investments in our Global Investment Management business, $8.8$25.5 million of which is expected to be funded during 2016.2017. In addition to required future capital contributions, some of theco-investment entities may request additional capital from us and our subsidiaries holding investments in those assets. However, our debt instruments contain restrictions that may limit our ability to provide capital to the entities holding direct or indirect interests inco-investments. The failure to provide these contributions could have adverse consequences to our interests in these investments, including damage to our reputation with ourco-investment partners and clients, as well as the necessity of obtaining alternative funding from other sources that may be on disadvantageous terms for us and the otherco-investors. Participating as aco-investor is an important part of our Global Investment Management business, which might suffer if we were unable to make these investments. Although our debt instruments contain restrictions that limit our ability to provide capital to the entities holding direct or indirect interests in co-investments, we may provide this capital in many instances in further support of the co-investment.

Selective investment in real estate projects is an important part of our Development Services business strategy, and there is an inherent risk of loss of our investments. As of December 31, 2015,2016, we had 10 consolidatednine real estate projects with invested equity of $9.1 million.consolidated in our financial statements. In addition, at December 31, 2015,2016, we were

involved as a principal (in most cases,co-investing with our clients) in approximately 60 unconsolidated real estate subsidiaries with invested equity of $121.9 million and had committed additional capital to these unconsolidated subsidiaries of $29.6$23.0 million. As of December 31, 2015,2016, we also guaranteed outstanding notes payable of these unconsolidated subsidiaries with outstanding balances of $12.4$15.7 million.

During the ordinary course of our Development Services business, we provide numerous completion and budget guarantees requiring us to complete the relevant project within a specified timeframe and/or within a specified budget, with us potentially being liable for costs to complete in excess of such timeframe or budget. While we generally have “guaranteed maximum price” contracts with reputable general contractors with respect to projects for which we provide these guarantees (which are intended to pass most of the risk to such contractors), there can be no assurance that we will not have to perform under any such guarantees. If we are required to perform under a significant number of such guarantees, it could harm our business, results of operations and financial condition.

Because the disposition of a single significant investment can affect our financial performance in any period, our real estate investment activities could cause fluctuations in our net earnings and cash flow. In many cases, we have limited control over the timing of the disposition of these investments and the recognition of any related gain or loss, or incentive participation fee.

Poor performance of the investment programs that our Global Investment Management business manages would cause a decline in our revenue, net income and cash flow and could adversely affect our ability to raise capital for future programs.

The revenue, net income and cash flow generated by our Global Investment Management business can be volatile period over period, primarily due to the fact that management, transaction and incentive fees can vary as a result of market movements from one period to another. In the event that any of the investment programs that our Global Investment Management business manages were to perform poorly, our revenue, net income and cash flow could decline because the value of the assets we manage would decrease, which would result in a reduction in some of our management fees, and our investment returns would decrease, resulting in a reduction in the incentive compensation we earn. Moreover, we could experience losses onco-investments of our own capital in such programs as a result of poor performance. Investors and potential investors in our programs continually assess our performance, and our ability to raise capital for existing and future programs and maintaining our current fee structure will depend on our continued satisfactory performance.

Our debt instruments impose operating and financial restrictions on us, and in the event of a default, all of our borrowings would become immediately due and payable.

We have debt and related debt service obligations. As of December 31, 2015,2016, our total debt, excluding notes payable on real estate (which are generally nonrecourse to us) and warehouse lines of credit (which are recourse only to our wholly-owned subsidiary, CBRE Capital Markets, and are secured by our related warehouse receivables), was approximately $2.7$2.6 billion. For the year ended December 31, 2015,2016, our interest expense was approximately $118.9$144.9 million.

Our debt instruments, including our credit agreement, impose, and the terms of any future debt may impose, operating and other restrictions on us and many of our subsidiaries. These restrictions affect, and in many respects limit or prohibit, our ability to:

Our credit agreement currently requires us to maintain a minimum coverage ratio of EBITDA (as defined in the 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 credit agreement) of 4.25x as of the end of each fiscal quarter. Our coverage ratio of EBITDA to total interest expense was 11.81x12.73x for the year ended December 31, 2015,2016, and our leverage ratio of total debt less available cash to EBITDA was 1.45x1.18x as of December 31, 2015.2016. Our ability to meet these financial ratios can be affected by events beyond our control, and we cannot give assurance that we will be able to meet those ratios when required. We continue to monitor our projected compliance with these financial ratios and other terms of our credit agreement.

A breach of any of these restrictive covenants or the inability to comply with the required financial ratios could result in a default under our debt instruments. If any such default occurs, the lenders under our credit agreement may elect to declare all outstanding borrowings, together with accrued interest and other fees, to be immediately due and payable. The lenders under our credit agreement also have the right in these circumstances to terminate any commitments they have to provide further borrowings. In addition, a default under our credit agreement could trigger a cross default or cross acceleration under our other debt instruments.

Our credit agreement is jointly and severally guaranteed by us and substantially all of our material domestic subsidiaries.

We have limited restrictions on the amount of additional recourse debt we are able to incur, which may intensify the risks associated with our leverage, including our ability to service our indebtedness. In addition, in the event of a credit-ratings downgrade, our ability to borrow and the costs of that borrowing could be adversely affected.

Subject to the maximum amounts of indebtedness permitted by our credit agreement covenants, we are not restricted in the amount of additional recourse debt we are able to incur, and so we may in the future incur such indebtedness in order to finance our operations and investments. In addition, Moody’s Investors Service, Inc. and Standard & Poor’s Ratings Services, a division of The McGraw-Hill Companies, Inc., rate our significant outstanding debt. These ratings, and any downgrades of them, may affect our ability to borrow as well as the costs of our current and future borrowings.

A significant portion of our revenue is seasonal, which could cause our financial results to fluctuate significantly.

A significant portion of our revenue is seasonal. Historically, our revenue, operating income, net income and cash flow from operating activities tend to be lowest in the first calendar quarter, and highest in the fourth calendar quarter of each year. Earnings and cash flow have generally been concentrated in the fourth calendar quarter due to the focus on completing sales, financing and leasing transactions prior to calendaryear-end. This variance among periods makes it difficult to compare our financial condition and results of operations on aquarter-by-quarter basis. In addition, as a result of the seasonal nature of our business, political, economic or other unforeseen disruptions occurring in the fourth quarter that impact our ability to close large transactions may have a disproportionate effect on our financial condition and results of operations.

We are subject to various litigation risks and may face financial liabilities and/or damage to our reputation as a result of litigation.

Our businesses are exposed to various litigation risks. In addition, although we maintain insurance coverage for most of this risk, insurance coverage is unavailable at commercially reasonable pricing for certain types of exposures. Accordingly, an adverse result in a litigation against us, or a lawsuit that results in a substantial legal liability for us (and particularly a lawsuit that is not insured), could have a disproportionate and material adverse effect on our business, financial condition and results of operations. In addition, we depend on our business relationships and our reputation for high-caliber professional services to attract and retain clients. As a result, allegations against us, irrespective of the ultimate outcome of that allegation, may harm our professional reputation and as such materially damage our business and its prospects.

A failure to appropriately deal with actual or perceived conflicts of interest could adversely affect our businesses.

Our company has a global platform with different business lines and a broad client base and is therefore subject to numerous potential, actual or perceived conflicts of interests in the provision of services to our existing and potential clients. For example, conflicts may arise from our position as broker to both owners and tenants in commercial real estate lease transactions. We have adopted various policies, controls and procedures to address or limit actual or perceived conflicts, but these policies and procedures may not be adequate and may not be adhered to by our employees. Appropriately dealing with conflicts of interest is complex and difficult and our reputation could be damaged and cause us to lose existing clients or fail to gain new clients if we fail, or appear to fail, to identify, disclose and manage potential conflicts of interest, which could have an adverse effect on our business, financial condition and results of operations. In addition, it is possible that in some jurisdictions regulations could be changed to limit our ability to act for parties where conflicts exist even with informed consent, which could limit our market share in those markets. There can be no assurance that conflicts of interest will not arise in the future that could cause material harm to us.

Failure to maintain and execute information technology strategies and ensure that our employees adapt to changes in technology could materially and adversely affect our ability to remain competitive in the market.

Our business relies heavily on information technology to deliver services that meet the needs of our clients. If we are unable to effectively execute our information technology strategies or adopt new technologies and processes relevant to our service platform, our ability to deliver high-quality services may be materially impaired. In addition, we make significant investments in new systems and tools to achieve competitive advantages and efficiencies. Implementation of such investments in information technology could exceed estimated budgets and we may experience challenges that prevent new strategies or technologies from being realized according to anticipated schedules. If we are unable to maintain current information technology and processes or encounter delays, or fail to exploit new technologies, then the execution of our business plans may be disrupted. Similarly, our employees require effective tools and techniques to perform functions integral to our business. Failure to successfully provide such tools and systems, or ensure that employees have properly adopted them, could materially and adversely impact our ability to achieve positive business outcomes.

Failure to maintain the security of our information and technology networks, including personally identifiable and client information, intellectual property and proprietary business information could significantly adversely affect us.

Security breaches and other disruptions of our information and technology networks could compromise our information and intellectual property and expose us to liability, reputational harm and significant remediation costs, which could cause material harm to our business and financial results. In the ordinary course of our business, we collect and store sensitive data, including our proprietary business information and intellectual property, and that of our clients and personally identifiable information of our employees and contractors, in our data centers and on our networks. The secure processing, maintenance and transmission of this information are critical to our operations. Despite our security measures, our information technology and infrastructure may be vulnerable to attacks by third parties or breached due to employee error, malfeasance or other disruptions. A significant actual or potential theft, loss, corruption, exposure, fraudulent use or misuse of client, employee or other personally identifiable or proprietary business data, whether by third parties or as a result of employee malfeasance or otherwise,non-compliance with our contractual or other legal obligations regarding such data or intellectual property or a violation of our privacy and security policies with respect to such data could result in significant remediation and other costs, fines, litigation or regulatory actions against us. Such an event could additionally disrupt our operations and the services we provide to clients, damage our reputation, result in the loss of a competitive advantage, impact our ability to provide timely and accurate financial data and cause a loss of confidence in our services and financial reporting, which could adversely affect our business, revenues, competitive position and investor confidence. Additionally, we increasingly rely on third-party data storage

providers, including cloud storage solution providers, resulting in less direct control over our data. Such third parties are also vulnerable to security breaches and compromised security systems, for which we may not be indemnified and which could materially adversely affect us and our reputation.

Interruption or failure of our information technology, communications systems or data services could impair our ability to provide our services effectively, which could damage our reputation and materially harm our operating results.

Our business requires the continued operation of information technology and communication systems and network infrastructure. Our ability to conduct our global business may be materially adversely affected by disruptions to these systems or infrastructure. Our information technology and communications systems are vulnerable to damage or disruption from fire, power loss, telecommunications failure, system malfunctions, computer viruses, cyber-attacks, natural disasters such as hurricanes, earthquakes and floods, acts of war or terrorism, employee errors or malfeasance, or other events which are beyond our control. In addition, the operation and maintenance of these systems and networks is in some cases dependent on third-party technologies, systems and service providers for which there is no certainty of uninterrupted availability. Any of these events could cause system interruption, delays and loss, corruption or exposure of critical data or intellectual property and may also disrupt our ability to provide services to or interact with our clients, and we may not be able to successfully implement contingency plans that depend on communication or travel. Furthermore, any such event could result in substantial recovery and remediation costs and liability to customers, business partners and other third parties. We have disaster recovery plans and backup systems to reduce the potentially adverse effect of such events, but our disaster recovery planning may not be sufficient and cannot account for all eventualities, and a catastrophic event that results in the destruction or disruption of any of our data centers or our critical business or information technology systems could severely affect our ability to conduct normal business operations, and as a result, our future operating results could be materially adversely affected.

The infrastructure disruptions we describe above may also disrupt our ability to manage real estate for clients or may adversely affect the value of real estate investments we make on behalf of clients. The buildings we manage for clients, which include some of the world’s largest office properties and retail centers, are used by numerous people daily. As a result, fires, earthquakes, floods, other natural disasters, defects and terrorist attacks can result in significant loss of life, and, to the extent we are held to have been negligent in connection with our management of the affected properties, we could incur significant financial liabilities and reputational harm.

Our business relies heavily on the use of commercial real estate data. A portion of this data is purchased or licensed from third-party providers for which there is no certainty of uninterrupted availability. A disruption of our ability to provide data to our professionals and/or our clients or an inadvertent exposure of proprietary data could damage our reputation and competitive position, and our operating results could be adversely affected.

We have numerous local and global competitors across all of our business lines and the geographies that we serve, and further industry consolidation could lead to significant future competition.

We compete across a variety of business disciplines within the commercial real estate services and investment industry, including commercial property and corporate facilities management, occupier and property/agency leasing, property sales, valuation, real estate investment management, commercial mortgage origination and servicing, capital markets (structured finance and debt) solutions, development services and proprietary research. Although we are the largest commercial real estate services firm in the world in terms of 2015 revenue, our relative competitive position varies significantly across geographies, property types and services and business lines. Depending on the geography, property type or service or business line, we face competition from other commercial real estate service providers and investment firms, including outsourcing companies that traditionally competed in limited portions of our facilities management business and have expanded their offerings from time to time, in-house corporate real estate departments, developers, institutional lenders, insurance companies, investment banking firms, investment managers and accounting and consulting firms. Some of these firms may have greater financial resources allocated to a particular geography, property type or service or business line than we have allocated that geography, property type, service or business line. In addition, future changes in laws could lead to the entry of other new competitors, such as financial institutions. Although many of our existing competitors are local or regional firms that are smaller than we are, some of these competitors are larger on a

local or regional basis. We are further subject to competition from large national and multi-national firms that have similar service and investment competencies to ours, and it is possible that further industry consolidation could lead to much larger and more formidable competitors globally or in the particular geographies, property types, service or business lines that we serve. There is no assurance that we will be able to compete effectively, to maintain current fee levels or margins, or maintain or increase our market share.

Our goodwill and other intangible assets could become impaired, which may require us to take significantnon-cash charges against earnings.

Under current accounting guidelines, we must assess, at least annually and potentially more frequently, whether the value of our goodwill and other intangible assets has been impaired. Any impairment of goodwill or other intangible assets as a result of such analysis would result in anon-cash charge against earnings, and such charge could materially adversely affect our reported results of operations, stockholders’ equity and our stock price. For example, during the year ended December 31, 2013, we recorded a non-amortizable intangible asset impairment of $98.1 million in our Global Investment Management segment. This non-cash write-off was related to a decrease in value of our open-end funds, primarily in Europe. A significant and sustained decline in our future cash flows, a significant adverse change in the economic environment, slower growth rates or if our stock price falls below our net book value per share for a sustained period, could result in the need to perform additional impairment analysis in future periods. If we were to conclude that a future write-down of goodwill or other intangible assets is necessary, then we would record such additional charges, which could materially adversely affect our results of operations.

A failure to appropriately deal with actual or perceived conflicts of interest could adversely affect our businesses.

Our company has a global platform with different business lines and a broad client base and is therefore subject to numerous potential, actual or perceived conflicts of interests in the provision of services to our existing and potential clients. For example, conflicts may arise from our position as broker to both owners and tenants in commercial real estate lease transactions. We have adopted various policies, controls and procedures to address or limit actual or perceived conflicts, but these policies and procedures may not be adequate and may not be adhered to by our employees. Appropriately dealing with conflicts of interest is complex and difficult and our reputation could be damaged and cause us to lose existing clients or fail to gain new clients if we fail, or appear to fail, to identify, disclose and manage potential conflicts of interest, which could have an adverse effect on our business, financial condition and results of operations. In addition, it is possible that in some jurisdictions regulations could be changed to limit our ability to act for parties where conflicts exist even with informed consent, which could limit our market share in those markets. There can be no assurance that conflicts of interest will not arise in the future that could cause material harm to us.

Our businesses, financial condition, results of operations and prospects could be adversely affected by new laws or regulations or by changes in existing laws or regulations or the application thereof. If we fail to comply with laws and regulations applicable to us, or make incorrect determinations in complex tax regimes, we may incur significant financial penalties.

We are subject to numerous federal, state, local andnon-U.S. laws and regulations specific to the services we perform in our business. Brokerage of real estate sales and leasing transactions and the provision of asset services and valuation services require us and our employees to maintain applicable licenses in each U.S. state and certainnon-U.S. jurisdictions in which we perform these services. If we and our employees fail to maintain our licenses or conduct these activities without a license, or violate any of the regulations covering our licenses, we may be required to pay fines (including treble damages in certain states) or return commissions received or have our licenses suspended or revoked. A number of our services, including the services provided by our indirect wholly-owned subsidiaries, CBRE Capital Markets and CBRE Global Investors, are subject to regulation by the SEC, FINRA or other self-regulatory organizations and state securities regulators and compliance failures

or regulatory action could adversely affect our business. We could be subject to disciplinary or other actions in the future due to claimed noncompliance with these regulations, which could have a material adverse effect on our operations and profitability.

We are also subject to laws of broader applicability, such as tax, securities, environmental and employment laws, including the Fair Labor Standards Act, occupational health and safety regulations and U.S. statewage-and-hour laws. Failure to comply with these requirements could result in the imposition of significant fines by governmental authorities, awards of damages to private litigants and significant amounts paid in legal fees or settlements of these matters.

We operate in many jurisdictions with complex and varied tax regimes, and are subject to different forms of taxation resulting in a variable effective tax rate. In addition, from time to time we engage in transactions across different tax jurisdictions. Due to the different tax laws in the many jurisdictions where we operate, we are often required to make subjective determinations. The tax authorities in the various jurisdictions where we carry on business may not agree with the determinations that are made by us with respect to the application of tax law. Such disagreements could result in disputes and, ultimately, in the payment of additional funds to the government authorities in the jurisdictions where we carry on business, which could have an adverse effect on our results of operations. In addition, changes in tax rules or the outcome of tax assessments and audits could have an adverse effect on our results in any particular quarter.

As the size and scope of our business has increased significantly during the past several years, both the difficulty of ensuring compliance with numerous licensing and other regulatory requirements and the possible loss resulting fromnon-compliance have increased. The global economic crisis has resulted in increased government and legislative activities, including the introduction of new legislation and changes to rules and regulations, which we expect will continue into the future. New or revised legislation or regulations applicable to our business, both within and outside of the United States, as well as changes in administrations or enforcement priorities may have an adverse effect on our business, including increasing the costs of regulatory compliance or preventing us from providing certain types of services in certain jurisdictions or in connection with certain transactions or clients. We are unable to predict how any of these new laws, rules, regulations and proposals will be implemented or in what form, or whether any additional or similar changes to laws or regulations, including the interpretation or implementation thereof, will occur in the future. Any such action could affect us in substantial and unpredictable ways and could have an adverse effect on our businesses, financial condition, results of operations and prospects.

We may be subject to environmental liability as a result of our role as a property or facility manager or developer of real estate.

Various laws and regulations impose liability on real property owners or operators for the cost of investigating, cleaning up or removing contamination caused by hazardous or toxic substances at a property. In

our role as a property or facility manager or developer, we could be held liable as an operator for such costs. This liability may be imposed without regard to the legality of the original actions and without regard to whether we knew of, or were responsible for, the presence of the hazardous or toxic substances. If we fail to disclose environmental issues, we could also be liable to a buyer or lessee of a property. If we incur any such liability, our business could suffer significantly as it could be difficult for us to develop or sell such properties, or borrow funds using such properties as collateral. In the event of a substantial liability, our insurance coverage might be insufficient to pay the full damages, or the scope of available coverage may not cover certain of these liabilities. Additionally, liabilities incurred to comply with more stringent future environmental requirements could adversely affect any or all of our lines of business.

Item 1B. Unresolved Staff Comments

None.

Item 2. Properties

We occupied the following offices, excluding affiliates, as of December 31, 2015:2016:

Some of our offices house employees of bothfrom our Global Investment Management and Development Services segments as well as employees offrom our other business segments. Often, the employees of these segments occupy separate suites in the same building in order to operate the businesses independently with standalone offices. We have provided above office totals by geographic region and not listed all ofrather than by business segment in order to avoid double counting our Global Investment Management and Development Services offices to avoid double counting.offices.

In general, these leased offices are fully utilized. The most significant terms of the leasing arrangements for our offices are the length of the lease and the rent. Our leases have terms varying in duration. The rent payable under our office leases varies significantly from location to location as a result of differences in prevailing commercial real estate rates in different geographic locations. Our management believes that no single office lease is material to our business, results of operations or financial condition. In addition, we believe there is adequate alternative office space available at acceptable rental rates to meet our needs, although adverse movements in rental rates in some markets may negatively affect our profits in those markets when we enter into new leases.

We do not own any of these offices.

Item 3. Legal Proceedings

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.

EBITDA and adjusted EBITDA are not recognized measurements under accounting principles generally accepted in the United States, or GAAP. When analyzing our operating performance, investors should use these measures in addition to, and not as an alternative for, their most directly comparable financial measure calculated and presented in accordance with GAAP. We generally use thesenon-GAAP financial measures to evaluate operating performance and for other discretionary purposes. We believe 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.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

We are the world’s largest commercial real estate services and investment firm, based on 20152016 revenue, with leading full-service operations in major metropolitan areas throughout the world. We offer a full range ofprovide services to occupiers, owners, lenders and investors in the office, retail, industrial, multifamily and other typeshotel sectors of commercial real estate. As of December 31, 2015, excluding independent affiliates,2016, we operated in more than 400approximately 450 offices worldwide with more than 70,00075,000 employees, excluding independent affiliates, providing commercial real estate services under the “CBRE” brand name, investment management services under the “CBRE Global Investors” brand name and development services under the “Trammell Crow Company” brand name. Our business is focused on several competencies, including commercial property, corporate facilities, project and transaction management, tenant/occupier and property/agency leasing, capital markets solutions (property sales, commercial mortgage brokerage, loan origination sales and servicing, and structured finance)servicing) real estate investment management, valuation, development services and proprietary research. We generate revenue from both management fees (large multi-year portfolio andper-project contracts) and from commissions on transactions. We have been included in theFortune500 since 2008 (ranking #259 in 2016) and among theFortune Most Admired Companies in the real estate sector for fourfive consecutive years.years, including 2017. In 2015,2016, we were ranked second among all companies onbyForbesas theBarron’s500, which evaluates companies on growth 15^th best employer in America, and financial performance. Additionally, the International Association of Outsourcing Professionals (IAOP) has ranked us among the top few outsourcing service providers across all industries for five consecutive years. Additionally, we were one of only two companies to be ranked in the top 12 in theBarron’s 500, which evaluates companies on growth and financial performance, in each of 2014, 2015 and 2016.

Critical Accounting Policies

Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States, or GAAP, which require managementus to make estimates and assumptions that affect reported amounts. The estimates and assumptions are based on historical experience and on other factors that management believeswe believe to be reasonable. Actual results may differ from those estimates. We believe that the following critical accounting policies represent the areas where more significant judgments and estimates are used in the preparation of our consolidated financial statements.

Revenue Recognition

In order for us to recognize revenue, four basic criteria must be met:

Our revenue recognition policies are consistent with these criteria. The judgments involved in revenue recognition include understanding the complex terms of agreements and determining the appropriate time and method to recognize revenue for each transaction based on such terms. Each transaction is evaluated to determine: (i) at what point in time or over what period of time revenue is earned; (ii) whether contingencies exist that impact the timing of recognition of revenue; and (iii) how and when such contingencies will be resolved. The timing of revenue recognition could vary if different judgments were made. Our revenues subject to the most judgment are brokerage commission revenue and incentive-based management and development fees. For a detailed discussion of our revenue recognition policies, see the Revenue Recognition section within Note 2 of the Notes to Consolidated Financial Statements set forth in Item 8 of this Annual Report on Form10-K, (this or this Annual Report).Report.

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.

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. In determining the fair values of assets and liabilities acquired in a business combination, we use a variety of valuation methods including present value, depreciated replacement cost, market values (where available) and selling prices less costs to dispose. We are responsible for determining the valuation of assets and liabilities and for the allocation of purchase price to assets acquired and liabilities assumed.

Assumptions must often be made in determining fair values, particularly where observable market values do not exist. Assumptions may include discount rates, growth rates, cost of capital, royalty rates, tax rates and remaining useful lives. These assumptions can have a significant impact on the value of identifiable assets and accordingly can impact the value of goodwill recorded. Different assumptions could result in different values being attributed to assets and liabilities. Since these values impact the amount of annual depreciation and amortization expense, different assumptions could also impact our statement of operations and could impact the results of future asset impairment reviews.

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 atwo-step process. The first step used to identify potential impairment involves comparing each reporting unit’s estimated fair value to its carrying value, including goodwill. We use a discounted cash flow approach to estimate the fair value of our reporting units. Management judgment is required in developing the assumptions for the discounted cash flow model. These assumptions include revenue growth rates, profit margin percentages, discount rates, etc. If the estimated fair value of a reporting unit exceeds its carrying value, goodwill is considered to not be impaired. If the carrying value exceeds estimated fair value, there is an indication of potential impairment and the second step is performed to measure the amount of impairment. The second step of the process involves the calculation of an implied fair value of goodwill for each reporting unit for which step one indicated impairment. The implied fair value of goodwill is determined by measuring the excess of the estimated fair value of the reporting unit as calculated in step one, over the estimated fair values of the individual assets, liabilities and identifiable intangibles as if the reporting unit was being acquired in a business combination. Due to the many variables inherent in the estimation of a business’s fair value and the relative size of our goodwill, if different assumptions and estimates were used, it could have an adverse effect on our impairment analysis.

During the year ended December 31, 2013, we recorded a non-amortizable intangible asset impairment of $98.1 million in our Global Investment Management segment. This non-cash write-off was related to a decrease in value of our open-end funds, primarily in Europe.

For additional information on goodwill and intangible asset impairment testing, see Notes 2 5 and 8 of the Notes to Consolidated Financial Statements set forth in Item 8 of this Annual Report.

Income Taxes

Income taxes are accounted for under the asset and liability method in accordance with the “Accounting for Income Taxes,” Topic of the Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, (Topic 740). Deferred.Deferred tax assets and liabilities are determined based on temporary

differences between the financial reporting and tax basis of assets and liabilities and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured by applying enacted tax rates and laws and are released in the years in which the temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are provided against deferred tax assets when it is more likely than not that some portion or all of the deferred tax asset will not be realized.

In November 2015, the FASB issued Accounting Standards Update, or ASU, 2015-17,“Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes” (ASU 2015-17). This ASU requires the offset of all deferred tax assets and liabilities, including valuation allowances, for each tax-paying jurisdiction within each tax-paying component. The net deferred tax must be presented as a single noncurrent amount. ASU 2015-17 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, with early adoption permitted. Entities may elect to use either a prospective or retrospective transition method. We elected to early adopt the provisions of ASU 2015-17 during the fourth quarter of 2015 and balance sheet amounts as of December 31, 2014 have been reclassified to conform with the current period presentation. As of December 31, 2014, $205.9 million of current deferred tax assets were reclassified to long term deferred tax assets.

Accounting for tax positions requires judgments, including estimating reserves for potential uncertainties. We also assess our ability to utilize tax attributes, including those in the form of carryforwards, for which the benefits have already been reflected in the financial statements. We do not record valuation allowances for deferred tax assets that we believe will be realized in future periods. While we believe the resulting tax balances as of December 31, 20152016 and 20142015 are appropriately accounted for in accordance with Topic 740, as applicable, the ultimate outcome of such matters could result in favorable or unfavorable adjustments to our consolidated financial statements and such adjustments could be material.

Our foreign subsidiaries have accumulated $1.4$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 ofnon-U.S. subsidiaries, these earnings are permanently reinvested outside of the United States and we do not have any plans to repatriate them or to sell or liquidate any of ournon-U.S. subsidiaries. To the extent that we are able to repatriate earnings in a tax efficient manner, we would be required to accrue and pay U.S. taxes to repatriate these funds, net of foreign tax credits. Determining our tax liability upon repatriation is not practicable. Cash and cash equivalents owned bynon-U.S. subsidiaries totaled $315.5$408.9 million at December 31, 2015. In 2013, we repatriated $196.2 million. Tax benefits associated with the release of valuation allowances on foreign tax credits of $14.5 million and $4.9 million were recorded in 2013 and 2014, respectively.2016.

See Note 13 of the Notes to Consolidated Financial Statements set forth in Item 8 of this Annual Report for further information regarding income taxes.

New Accounting Pronouncements

See New Accounting Pronouncements section within Note 2 of the Notes to Consolidated Financial Statements set forth in Item 8 of this Annual Report.

Seasonality

A significant portion of our revenue is seasonal, which an investor should keep in mind when comparing our financial condition and results of operations on aquarter-by-quarter basis. Historically, our revenue, operating income, net income and cash flow from operating activities tend to be lowest in the first quarter, and highest in the fourth quarter of each year. Revenue, earnings and cash flow have generally been concentrated in the fourth calendar quarter due to the focus on completing sales, financing and leasing transactions prior toyear-end.

Inflation

Our commissions and other variable costs related to revenue are primarily affected by commercial real estate market supply and demand, which may be affected by inflation. However, to date, we do not believe that general inflation has had a material impact upon our operations.

Items Affecting Comparability

When you read our financial statements and the information included in this Annual Report on Form10-K, you should consider that we have experienced, and continue to experience, several material trends and uncertainties that have affected our financial condition and results of operations that make it challenging to predict our future performance based on our historical results. We believe that the following material trends and uncertainties are crucial to an understanding of the variability in our historical earnings and cash flows and the potential for continued variability in the future.

Macroeconomic Conditions

Economic trends and government policies affect global and regional commercial real estate markets as well as our operations directly. These include: overall economic activity and employment growth; interest rate levels and changes in interest rates; the cost and availability of credit; and the impact of tax and regulatory policies. Periods of economic weakness or recession, significantly rising interest rates, fiscal uncertainty, declining

employment levels, decreasing demand for commercial real estate, falling real estate values, disruption to the global capital or credit markets, or the public perception that any of these events may occur, will negatively affect the performance of our business.

Compensation is our largest expense and the sales and leasing professionals in our advisory services business generally are paid on a commission and/or bonus basis that correlates with their revenue production. As a result, the negative effect of difficult market conditions on our operating margins is partially mitigated by the inherent variability of our compensation cost structure. In addition, when negative economic conditions have been particularly severe, we have moved decisively to lower operating expenses to improve financial performance, and then have restored certain expenses as economic conditions improved. Nevertheless, adverse global and regional economic trends could pose significant risks to the performance of our operations and our financial condition.

Commercial real estate markets have recovered over the past several years, along with the steady improvement in global economic activity, most particularly in the United States. Since 2010, increased U.S. property sales activity has been sustained by gradually improving market fundamentals, low-cost credit availability and increased global and domestic capital flows. During this time, U.S. leasing markets have been marked by increased demand for space, falling vacancies and higher rents. During this time, healthy U.S. property sales activity has been sustained by gradually improving market fundamentals,low-cost credit availability and increased global and domestic capital flows. Property sales volumes slowed in 2016 following several years of strong growth; however, the market remained active. Commercial mortgage services activity rose in 2016 driven by lower interest rates and a favorable lending environment. Lending for multi-family properties in the United States was particularly robust, reflecting strong activity with U.S. Government Sponsored Enterprises (GSEs) as well as a long-term trend of increased renting versus home ownership in the United States.

European economies began to emerge from recession in 2013, with most countries returning to positive, albeit modest, economic growth. Reflecting the macro environment,Sales and leasing marketsactivity in Europe has improved across most of Europe were slowfor much of the past two years. An exception is London, where uncertainty in advance of and following the United Kingdom’s referendum to recover, but improved significantly in 2015. Buoyed by low-cost creditleave the European Union, commonly referred to as “Brexit,” constrained occupier and continued capital flows, Europe saw increased property salesinvestor activity in 2015, with higher volumes occurring across more markets, particularly on the continent.2016.

In Asia Pacific, the performance of real estate leasing and investment markets has varied from country to country amid slowing economic growth. Strength in Australia hasLeasing and investment market activity was generally compensatedsoft for slower activity elsewheremuch of 2016, but picked up noticeably in the region.

Effects of Acquisitions

The CompanyWe historically hashave made significant use of strategic acquisitions to add new service competencies, to increase our scale within existing competencies and to expand our presence in various geographic regions around

the world. On September 1,September1, 2015, CBRE, Inc., our wholly-owned subsidiary, closed onpursuant to a Stock and Asset Purchase Agreement (the Purchase Agreement) with Johnson Controls, Inc. (JCI) to acquire, acquired JCI’s Global Workplace Solutions (GWS)(JCI-GWS) business (which we refer to as the GWS Acquisition). The acquired GWSJCI-GWS business iswas a market-leading provider of integrated facilities management solutions for major occupiers of commercial real estate and hashad significant operations around the world. The purchase price was $1.475 billion, paid in cash, withplus adjustments totaling $46.5 million for working capital and other items. We completed the GWS Acquisition in order to advance our strategy of delivering globally integrated services to major occupiers in our Americas, EMEA and Asia Pacific segments. We merged the acquired GWSJCI-GWS business with our existing occupier outsourcing business line, and the new combined business adopted the “Global Workplace Solutions” name.

Strategicin-fill acquisitions have also played a key role in expanding our geographic coverage and broadening and strengthening our service offerings. The companies we acquired have generally been regional or
