Basis of Presentation and Use of Estimates Basis of Presentation and Use of Estimates
The Consolidated Financial Statements of Affiliated Managers Group, Inc. (“AMG” or the “Company”) have been
prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) for interim financial information
and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X.  Accordingly, they do not include all of the
information and footnotes required by GAAP for full year financial statements.  In the opinion of management, all normal and
recurring adjustments considered necessary for a fair statement of the Company’s interim financial position and results of
operations have been included and all intercompany balances and transactions have been eliminated.  Operating results for
interim periods are not necessarily indicative of the results that may be expected for any other period or for the full year.  The
Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 includes additional information about its
operations, financial position, and accounting policies, and should be read in conjunction with this Quarterly Report on
Form 10-Q.
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions
that affect the reported amounts and disclosures in the financial statements.  Actual results could differ from those estimates.
All amounts in these notes, except per share data in the text and tables herein, are stated in millions unless otherwise
indicated
