Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Principles of Consolidation | Basis of Presentation and Use of Estimates The Consolidated Financial Statements of Affiliated Managers Group, Inc. (the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“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 complete financial statements. In the opinion of management, all adjustments considered necessary for a fair statement of the results have been included. All intercompany balances and transactions have been eliminated. Certain reclassifications have been made to the prior period’s financial statements to conform to the current period’s presentation. 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, 2015 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 accordance 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. Principles of Consolidation The Company assesses consolidation requirements pursuant to ASU 2015-02: Consolidation, which was adopted using the modified retrospective method and resulted in an effective date of adoption of January 1, 2016. In evaluating whether an investment must be consolidated, the Company evaluates the risk, rewards, and significant terms of each of its Affiliate and other investments to determine if its investments are considered a voting rights entity (“VRE”) or a variable interest entity (“VIE”). An entity is a VRE when the total equity investment at risk is sufficient to enable the entity to finance its activities independently and when the equity holders have the obligation to absorb losses, the right to receive residual returns and the right to direct the activities of the entity that most significantly impact its economic performance. An entity is a VIE when it lacks one or more of the characteristics of a VRE. Assessing whether an entity is a VRE or VIE involves judgment. Upon the occurrence of certain events, management reviews and reconsiders its previous conclusion regarding the status of an entity as a VRE or a VIE. The Company consolidates VREs when it has control over significant operating, financial and investing decisions of the investment or holds the majority voting interest. The Company consolidates VIEs when it has a controlling financial interest, which is defined as having the power to direct the activities that most significantly impact the VIE’s economic performance and the obligation to absorb losses of or the right to receive benefits from the entity that could potentially be significant to the VIE. Investments in Affiliates For the Company’s consolidated Affiliates, the portion of the Owners’ Allocation allocated to Affiliate management is included in Net income (non-controlling interests) in the Consolidated Statements of Income. Non-controlling interests on the Consolidated Balance Sheets include capital and undistributed Operating and Owners’ Allocation owned by Affiliate management of the Company’s consolidated Affiliates. The effect of any changes in the Company’s equity interests in its consolidated Affiliates resulting from the issuance or repurchase of an Affiliate’s equity by the Company or one of its Affiliates is included as a component of stockholders’ equity, net of the related income tax effect in the period of the change. The current redemption value of non-controlling interests has been presented as Redeemable non-controlling interests on the Consolidated Balance Sheets. AMG applies the equity method of accounting to investments where AMG does not hold a controlling equity interest but has the ability to exercise significant influence over operating and financial matters. Other investments in which AMG owns less than a 20% interest and does not exercise significant influence are accounted for under the cost method. Under the cost method, income is recognized as dividends when, and if, declared. Affiliate Sponsored Investment Products The Company’s consolidated Affiliates sponsor various investment products where they also act as the investment advisor, and in some cases these products are considered VIEs. These investment products are typically owned primarily by third-party investors; however, certain products are capitalized with seed capital investments from Affiliates. Investors are generally entitled to substantially all of the economics of these VIEs, except for the management and performance fees earned by Affiliates or any gains or losses attributable to Affiliates’ investments in these products. As a result, Affiliates do not generally consolidate these VIEs unless the Affiliate’s interest in the product is considered substantial. When consolidating these VIEs, the Company retains the specialized investment company accounting principles of the underlying products, and all of the underlying investments are carried at fair value in Investments in marketable securities in the Consolidated Balance Sheets with corresponding changes in the investments’ fair values reflected in Other operating expenses in the Consolidated Statements of Income. Purchases and sales of securities are presented within Decrease in payables, accrued liabilities and other liabilities and Increase in other assets, respectively, in the Consolidated Statements of Cash Flows. When Affiliates no longer control these products, due to a reduction in ownership or other reasons, the products are deconsolidated.
