Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Readers of this Quarterly Report on Form 10-Q (Quarterly Report) should refer to the audited financial statements and notes to 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”), for the year ended December 31, 2022, which are included in our 2022 Annual Report on Form 10-K (2022 Annual Report), filed with the United States Securities and Exchange Commission (SEC) and also available on our website (www.cbre.com), since we have omitted from this Quarterly Report certain footnote disclosures which would substantially duplicate those contained in such audited financial statements. You should also refer to Note 2, Significant Accounting Policies, in the notes to consolidated financial statements in our 2022 Annual Report for further discussion of our significant accounting policies and estimates. Considerations Related to Current Macroeconomic Conditions The macroeconomic environment remains challenging as central banks rapidly raised interest rates since 2022. The high rate environment and the expectation that rates will remain higher for longer, coupled with large bank failures in early 2023 and ongoing economic uncertainty, has limited credit availability to commercial real estate. Less available and more expensive debt capital has had pronounced effects on our capital markets (mortgage origination and property sales) businesses, making property acquisitions and dispositions harder to finance. Similar factors also impact the timing and value of asset and fund monetization in our investment management and development businesses and our ability to source new debt capital to fund development projects. Financial Statement Preparation The accompanying consolidated financial statements 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 (U.S.), or General Accepted Accounting Principles (GAAP), for annual financial statements. In our opinion, 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 us to make estimates and assumptions about future events, such as weakening global macroeconomic conditions and stress in the banking system, including less available and more expensive debt capital. These estimates and the underlying assumptions affect the reported amounts of assets, liabilities, revenues and expenses. Such estimates include the value of goodwill, intangibles and other long-lived assets, real estate assets, accounts receivable, contract assets, operating lease assets, 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 our best judgment. We evaluate our estimates and assumptions on an ongoing basis using historical experience and other factors, including consideration of the current economic environment, and adjust 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.
