1. Basis of Presentation

The accompanying consolidated financial statements of CBRE Group, Inc., a Delaware corporation (which may be referred to in these financial statements as the “company”, “we”, “us” and “our”), have been prepared in accordance with the rules applicable to Quarterly Reports on Form 10-Q and include all information and footnotes required for interim financial statement presentation, but do not include all disclosures required under accounting principles generally accepted in the United States (GAAP) for annual financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments, except as otherwise noted) considered necessary for a fair presentation have been included. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, and reported amounts of revenue and expenses. Such estimates include the value of goodwill, intangibles and other long-lived assets, real estate assets, accounts receivable, investments in unconsolidated subsidiaries and assumptions used in the calculation of income taxes, retirement and other post-employment benefits, among others. These estimates and assumptions are based on management’s best judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including consideration of the current economic environment, and adjusts such estimates and assumptions when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in these estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods. Certain reclassifications have been made to the 2012 financial statements to conform with the 2013 presentation.

The results of operations for the three and six months ended June 30, 2013 are not necessarily indicative of the results of operations to be expected for the year ending December 31, 2013. The unaudited interim consolidated financial statements and notes to consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2012, which contains the latest available audited consolidated financial statements and notes thereto, which are as of and for the year ended December 31, 2012.

2. New Accounting Pronouncements

In March 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2013-05, “Foreign Currency Matters (Topic 830): Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity.” This ASU states that when a reporting entity (parent) ceases to have a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business (other than a sale of in substance real estate or conveyance of oil and gas mineral rights) within a foreign entity, the parent is required to apply the guidance in Subtopic 830-30 to release any related cumulative translation adjustment into net income. Accordingly, the cumulative translation adjustment should be released into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. ASU 2013-05 is effective prospectively for fiscal years (and interim reporting periods within those years) beginning after December 15, 2013, with early adoption permitted. We do not believe the adoption of this update will have a material effect on our consolidated financial position or results of operations.

In July 2013, the FASB issued ASU 2013-10, “Derivatives and Hedging (Topic 815): Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes.” This ASU permits the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) to be used as a U.S. benchmark interest rate for hedge accounting purposes, in addition to U.S. treasury rates and LIBOR. This ASU also removes the restriction on using different benchmark rates for similar hedges. This ASU applies to all entities that elect to apply hedge accounting of the benchmark interest rate. This ASU is effective prospectively for

qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. We do not believe the adoption of this update will have a material effect on our consolidated financial position or results of operations.

In July 2013, the FASB issued ASU 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” This ASU states that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows: To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. This ASU applies to all entities that have unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013, with early adoption permitted. This ASU should be applied prospectively to all unrecognized tax benefits that exist at the effective date, with retrospective application permitted. We do not believe the adoption of this update will have a material impact on our consolidated financial position.

3. Variable Interest Entities (VIEs)

A consolidated subsidiary (the Venture) in our Global Investment Management segment has sponsored investments by third-party investors in certain commercial properties through the formation of tenant-in-common limited liability companies and Delaware Statutory Trusts (collectively referred to as the Entities) that are owned by the third-party investors. The Venture also has formed and is a member of a limited liability company for each property that serves as master tenant (Master Tenant). Each Master Tenant leases the property from the Entities through a master lease agreement. Pursuant to the master lease agreements, the Master Tenant has the power to direct the day-to-day asset management activities that most significantly impact the economic performance of the Entities. As a result, the Entities were deemed to be VIEs since the third-party investors holding the equity investment at risk in the Entities do not direct the day-to-day activities that most significantly impact the economic performance of the properties held by the Entities. The Venture has made and may continue to make voluntary contributions to each of these properties to support their operations beyond the cash flow generated by the properties themselves. As of the most recent reconsideration date, such financial support has been significant enough that the Venture was deemed to be the primary beneficiary of each Entity.

During the six months ended June 30, 2012, the Venture funded $0.2 million of financial support to the Entities.

Operating results relating to the Entities for the three and six months ended June 30, 2013 and 2012 include the following (dollars in thousands):

Investments in real estate of $40.8 million and $58.8 million and nonrecourse mortgage notes payable of $41.5 million ($0.9 million of which is current) and $61.7 million ($1.3 million of which is current) are included in real estate assets held for investment and notes payable on real estate, respectively, in the accompanying consolidated balance sheets as of June 30, 2013 and December 31, 2012, respectively. In addition, non-controlling deficits of $0.8 million and $2.7 million in the accompanying consolidated balance sheets as of June 30, 2013 and December 31, 2012, respectively, are attributable to the Entities.

We hold variable interests in certain VIEs in our Global Investment Management and Development Services segments which are not consolidated as it was determined that we are not the primary beneficiary. Our involvement with these entities is in the form of equity co-investments and fee arrangements.

In connection with our acquisition of Clarion Real Estate Securities (CRES) in 2011, we acquired CRES co-investments from ING Group N.V. in three funds (CRES Funds). In January 2012, one of the CRES Funds (CBRE Clarion U.S., L.P.) was converted to a registered mutual fund, the CBRE Clarion Long/Short Fund (the Fund). As a result of this triggering event, we determined that the Fund became a VIE and that we were not the primary beneficiary. Accordingly, in the first quarter of 2012, the Fund was deconsolidated from our consolidated financial statements and we recorded an investment in available for sale securities of $14.3 million. No gain or loss was recognized in our consolidated statement of operations as a result of this deconsolidation. During the second quarter of 2013, we fully redeemed our investment in the Fund. We continue to act as the Fund’s adviser, make investment decisions for the Fund and review, supervise and administer the Fund’s investment program.

As of June 30, 2013 and December 31, 2012, our maximum exposure to loss related to the VIEs which are not consolidated was as follows (dollars in thousands):

4. Fair Value Measurements

The “Fair Value Measurements and Disclosures” Topic of the FASB Accounting Standards Codification (ASC) (Topic 820) defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Topic 820 also establishes a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:
