NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.     Basis of Presentation

        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 United States of America 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 accounting principles generally accepted in the United States of America for complete financial statements. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all of the disclosures required by accounting principles generally accepted in the United States of America. 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, 2011 includes additional information about AMG, its operations, financial position and accounting policies, and should be read in conjunction with this Quarterly Report on Form 10-Q.

        All dollar amounts in these notes, except per share data in the text and tables herein, are stated in millions unless otherwise indicated.

2.     Senior Bank Debt

        The Company entered into a $1.0 billion senior unsecured credit facility in November 2011 (the "credit facility"), consisting of a $750.0 million revolving credit facility (the "revolver") and a $250.0 million term loan (the "term loan"), the principal terms of which are similar to the Company's previous senior unsecured credit facility. The term loan and $720.0 million of the revolver have a five-year maturity (maturing November 2016); the remaining $30.0 million of the revolver matures in January 2015. Subject to certain conditions, the Company may increase the revolver and the term loan by up to $150.0 million and $250.0 million, respectively.

        The credit facility is unsecured and contains financial covenants with respect to leverage and interest coverage, as well as customary affirmative and negative covenants, including limitations on indebtedness, liens, cash dividends, asset dispositions and fundamental corporate changes. As of March 31, 2012, the Company was in compliance with all terms of its credit facility.

        As further described in Note 13, the Company has entered into interest rate swap contracts to exchange a fixed rate for the variable rate on a portion of its credit facility.

The carrying values of the Company's convertible securities are as follows:

	December 31, 2011				March 31, 2012
	Carrying Value		Principal amount at maturity		Carrying Value		Principal amount at maturity

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(4)

These convertible securities are considered contingent payment debt instruments under federal income tax regulations, which require the Company to deduct interest in an amount greater than its reported Interest expense. These deductions will result in deferred tax liabilities of approximately $24.5 million in 2012. These deferred tax liabilities will be reclassified directly to stockholders' equity if the Company's common stock is trading above certain thresholds at the time of the conversion of the securities.

4.     Forward Equity Sale Agreements

        In July 2011, the Company entered into a forward equity sale agreement with two major securities firms under which it may sell shares of common stock with an aggregate sales price of up to $300.0 million. This agreement replaced all then outstanding forward equity sale agreements. As of March 31, 2012, no forward equity sales have occurred.

5.     Income Taxes

        The consolidated income tax provision includes taxes attributable to the controlling interest and, to a lesser extent, taxes attributable to non-controlling interests as follows:

	For the Three Months Ended March 31,
	2011			2012
Controlling Interests:
Current tax	$	13.5		$	8.0
Intangible related deferred taxes		12.9			9.9
Other deferred taxes		(2.8	)		2.9

        The components of deferred tax assets and liabilities are as follows:

Total deferred tax assets		83.8			81.6

Deferred tax assets, net of valuation allowance	$	48.2		$	47.0
Deferred Tax Liabilities
Intangible asset amortization	$	(247.1	)	$	(257.3	)
Convertible securities interest		(171.1	)		(175.5	)
Non-deductible intangible amortization		(127.2	)		(126.5	)
Deferred revenue		(5.6	)		(10.5	)
Other		(3.2	)		(3.0	)
Total deferred tax liabilities		(554.2	)		(572.8	)
Net deferred tax liability	$	(506.0	)	$	(525.8	)

        Deferred tax liabilities are primarily the result of tax deductions for the Company's intangible assets and convertible securities. The Company amortizes most of its intangible assets for tax purposes only, reducing its tax basis below its carrying value for financial statement purposes and generating deferred taxes each reporting period. The Company's 2008 senior convertible notes and junior convertible trust preferred securities also generate deferred tax liabilities because the Company's tax deductions are higher than the interest expense recorded for financial statement purposes.

        At March 31, 2012, the Company has state net operating loss carryforwards that expire over a 15-year period beginning in 2011. The Company also has foreign tax credit carryforwards that expire over a 10-year period beginning in 2011. The valuation allowances at December 31, 2011 and March 31, 2012 were principally related to the Company's ability to generate sufficient taxable income prior to the expiration of these carryforwards.

        The Company carried a liability for uncertain tax positions of $21.8 million as of March 31, 2012. These amounts included $1.7 million of interest and related charges. The Company does not anticipate that this liability will change significantly over the next twelve months.

        The Company periodically has tax examinations in the United States and foreign jurisdictions. Examination outcomes, and any related settlements, are subject to significant uncertainty. The completion of examinations may result in the payment of additional taxes and/or the recognition of tax benefits.

6.     Earnings Per Share

        The calculation of basic earnings per share is based on the weighted average number of shares of the Company's common stock outstanding during the period. Diluted earnings per share is similar to basic earnings per share, but adjusts for the dilutive effect of the potential issuance of incremental shares of the Company's common stock. The following is a reconciliation of the numerator and denominator used in the calculation of basic and diluted earnings per share available to common stockholders.

	For the Three Months Ended March 31,
	2011		2012
Numerator:
Net income (controlling interest)	$	39.1	$	37.4
Denominator:
Average shares outstanding—basic		51.8		51.6
Effect of dilutive instruments:
Stock options and other awards		1.3		1.3
Average shares outstanding—diluted		53.1		52.9

        As more fully discussed in Note 3, the Company had convertible securities outstanding during the periods presented and is required to apply the if-converted method to these securities in its calculation of diluted earnings per share. Under the if-converted method, shares that are issuable upon conversion are deemed outstanding, regardless of whether the securities are contractually convertible into the Company's common stock at that time. For this calculation, the interest expense (net of tax) attributable to these dilutive securities is added back to Net income (controlling interest), reflecting the assumption that the securities have been converted. Issuable shares for these securities and related interest expense are excluded from the calculation if an assumed conversion would be anti-dilutive to diluted earnings per share.

        For the three months ended March 31, 2012, the Company repurchased approximately 0.3 million shares of common stock under the share repurchase programs approved by the Company's Board of Directors.

        The diluted earnings per share calculations in the table above exclude the anti-dilutive effect of the following shares:

	For the Three Months Ended March 31,
	2011		2012
Stock options and other awards		0.6		1.2
Senior convertible securities		4.2		4.2
Junior convertible trust preferred securities		3.7		3.7

        As discussed further in Note 16, the Company may settle portions of its Affiliate equity purchases in shares of its common stock. Because it is the Company's intent to settle these potential repurchases in cash, the calculation of diluted earnings per share excludes any potential dilutive effect from possible share settlements.

7.     Commitments and Contingencies

        The Company and its Affiliates are subject to claims, legal proceedings and other contingencies in the ordinary course of their business activities. Each of these matters is subject to various uncertainties, and it is possible that some of these matters may be resolved in a manner unfavorable to the Company or its Affiliates. The Company and its Affiliates establish accruals for matters for which the outcome is probable and the amount of the liability can be reasonably estimated. Management believes that any liability in excess of these accruals upon the ultimate resolution of these matters will not have a material adverse effect on the Company.

        Certain Affiliates operate under regulatory authorities which require that they maintain minimum financial or capital requirements. Management is not aware of any significant violations of such financial requirements occurring during the period.

        In connection with its investment in Pantheon Ventures, the Company has committed to co-invest in certain investment partnerships where it serves as the general partner. As of March 31, 2012, these commitments totaled approximately $80.6 million and may be called in future periods. Russell Investments (Pantheon Ventures' former owner) is contractually obligated to reimburse the Company for $45.6 million of these commitments if they are called.

        Under past acquisition agreements, the Company is contingently liable, upon achievement of specified financial targets, to make payments of up to $496.3 million through 2017. As of March 31, 2012, the Company expects to make payments of $99.9 million to settle these contingent obligations in 2012–2015 (these payments are calculated to have a net present value of $83.1 million), of which $72.0 million is expected to be settled in the fourth quarter of 2012 and the remainder to be settled between 2014 and 2015. In the first quarter of 2012, the Company reduced its current estimate of payments to be made under these agreements and recognized a gain of $9.9 million ($5.0 million attributable to the controlling interest). This gain has been classified within Imputed interest expense and contingent payment arrangements in the Consolidated Statements of Income.

8.     Investments

Investments in Marketable Securities

        Investment in marketable securities at December 31, 2011 and March 31, 2012 were $100.4 million and $122.6 million, respectively. These investments are comprised of the Company's investments in Value Partners Group Limited ("Value Partners"), a publicly-traded asset management firm based in Hong Kong, and investments held by Affiliates.

The income or loss related to these investments is classified within Investment and other income in the Consolidated Statements of Income.

9.     Fair Value Measurements

        The Company determines the fair value of certain investment securities and other financial and nonfinancial assets and liabilities. Fair value is determined based on the price that would be received for an asset or paid to transfer a liability in the principal market for the asset or liability, or absent a principal market, the most advantageous market for the asset or liability, utilizing a hierarchy of three different valuation techniques:

Level 1—Unadjusted quoted market prices for identical instruments in active markets;

Level 2—Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs, or significant value drivers, are observable; and

Level 3—Prices reflect the Company's own assumptions concerning unobservable inputs to the valuation model. These inputs require significant management judgment and reflect the Company's estimation of assumptions that market participants would use in pricing the asset or liability.

        The following table summarizes the Company's assets and liabilities that are measured at fair value on a recurring basis:

        The following is a description of the significant assets and liabilities measured at fair value and the fair value methodologies used.

Cash equivalents consist primarily of highly liquid investments in money market funds. Cash investments in actively traded money market funds are classified as Level 1.

16

AFFILIATED MANAGERS GROUP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Investments in marketable securities consist primarily of investments in publicly traded securities and in funds advised by Affiliates which are valued using net asset value ("NAV"). These investments are classified as Level 1.

Other investments are valued using NAV. Investments in actively traded funds that calculate daily NAVs are classified as Level 1. Investments in funds that permit redemptions monthly or quarterly are classified as Level 2. Investments in funds that are subject to longer redemption restrictions are classified as Level 3. The fair value of Level 3 assets is determined using NAV one quarter in arrears (adjusted for current period calls and distributions).

Interest rate derivatives include interest rate swaps. The fair value of these assets is determined by model-derived valuations in which all significant inputs were observable in active markets.

Contingent payment arrangements represent the present value of the expected future settlement of contingent payment arrangements related to the Company's business combinations. The significant unobservable inputs used in the fair value measurement of these obligations are growth and discount rates. Increases in the growth rate would result in a higher obligation while an increase in the discount rate would result in a lower obligation.

Obligations to related parties include agreements to repurchase Affiliate equity and liabilities offsetting certain investments which are held by the Company but economically attributable to a related party. The significant unobservable inputs used in the fair value measurement of the agreements to repurchase Affiliate equity are growth and discount rates. Increases in the growth rate would result in a higher obligation while an increase in the discount rate would result in a lower obligation. The liability to a related party is measured based upon certain investments held by the Company, the fair value of which is determined using NAV.

        The following table presents certain quantitative information about the significant unobservable inputs used in valuing our Level 3 liabilities:

	Quantitative Information about Level 3 Fair Value Measurements
	Fair Value at March 31, 2012		Valuation Techniques	Unobservable Input	Range

        During the three months ended March 31, 2012, financial assets valued at $2.0 million were transferred from Level 1 to Level 2. There were no significant transfers of financial assets or liabilities in the three months ended March 31, 2011.

        The Company relies on the NAV of certain investments as their fair value. The NAVs have been derived from the fair values of the underlying investments as of the measurement dates. The following table summarizes, as of December 31, 2011 and March 31, 2012, the nature of these investments and any related liquidation restrictions or other factors which may impact the ultimate value realized:

	December 31, 2011				March 31, 2012
Category of Investment	Fair Value		Unfunded Commitments		Fair Value		Unfunded Commitments
Private equity fund-of-funds(1)	$	103.4	$	80.5	$	107.5	$	84.4
Other funds(2)		47.2		—		67.5		—
	$	150.6	$	80.5	$	175.0	$	84.4

(1)

These funds primarily invest in a broad range of private equity funds, as well as making direct investments. Distributions will be received as the underlying assets are liquidated over the life of the funds, generally 15 years.

(2)

These are multi-disciplinary funds that invest across various asset classes and strategies including long/short equity, credit and real estate. Investments are generally redeemable on a daily or quarterly basis.

        There are no current plans to sell any of these investments.

        The carrying value of senior bank debt approximates fair value because the debt is a credit facility with variable interest based on selected short-term rates. The fair market value of the 2008 senior convertible notes and the junior convertible trust preferred securities at March 31, 2012 was $516.4 million and $664.0 million, respectively. These securities are classified as Level 2 because the fair value was determined utilizing observable inputs in non-active markets.

10.   Variable Interest Entities

Sponsored Investment Funds

        The Company's Affiliates act as the investment manager for certain investment funds that are considered variable interest entities ("VIEs"). In addition to an Affiliate's involvement as the investment manager, Affiliates may also hold investments in these products. Affiliates are not the primary beneficiary of these VIEs as their involvement is limited to that of a service provider and their investment, if any, represents an insignificant interest in the fund's assets under management. As a result, the Company's variable interests will not absorb the majority of the variability of the entity's net assets and therefore the Company has not consolidated these entities.

Trust Preferred Vehicles

        The Company established wholly-owned trusts in connection with the 2006 and 2007 issuances of junior convertible trust preferred securities. These entities are considered VIEs and the Company is not the primary beneficiary, therefore these entities are not consolidated in the Company's financial statements.

        The net assets and liabilities of these unconsolidated VIEs and the Company's maximum risk of loss related thereto are as follows:

	December 31, 2011				March 31, 2012
	Unconsolidated VIE Net Assets		Carrying Value and Maximum Exposure to Loss		Unconsolidated VIE Net Assets		Carrying Value and Maximum Exposure to Loss
Sponsored investment funds	$	3,618.4	$	1.1	$	4,104.6	$	1.6
Trust preferred vehicles		9.0		9.0		9.0		9.0

11.   Related Party Transactions

        The Company periodically records amounts receivable and payable to Affiliate partners in connection with the transfer of Affiliate equity interests. The Company also has liabilities to related parties for deferred purchase price and contingent payment arrangements in connection with certain business combinations as well as liabilities offsetting certain investments which are held by the Company but economically attributable to a related party.

        The total receivable at December 31, 2011 was $41.3 million, of which $1.4 million is included in Prepaid expenses and other current assets and $39.9 million is included in Other assets. The total receivable at March 31, 2012 was $40.0 million, of which $1.5 million is included in Prepaid expenses and other current assets and $38.5 million is included in Other assets. The total payable as of December 31, 2011 was $147.5 million, of which $33.2 million is included in current liabilities and $114.3 million is included in Other long-term liabilities. The total payable as of March 31, 2012 was $132.2 million, of which $17.1 million is included in current liabilities and $115.1 million is included in Other long-term liabilities.

        In certain cases, Affiliate management owners and Company officers may serve as trustees or directors of certain mutual funds from which the Affiliate earns advisory fee revenue.

Exercisable at March 31, 2012		2.7			62.91		3.6

        The Company's Net income (controlling interest) for the three months ended March 31, 2011 includes compensation expense of $3.8 million (net of income tax benefits of $2.3 million) related to the Company's Stock Option and Incentive, Executive Incentive, Long-Term Equity Interests and Deferred Compensation Plans as compared to compensation expense of $5.0 million (net of income tax benefits of $3.1 million) for the three months ended March 31, 2012. As of March 31, 2012, the Company expects to recognize compensation expense related to these share-based compensation arrangements of $71.8 million over a weighted average period of approximately three years (assuming no forfeitures). As of March 31, 2012, no outstanding options have expiration dates prior to the end of 2012.

13.   Derivative Financial Instruments

        From time to time, the Company seeks to offset its exposure to changing interest rates under its debt financing arrangements by entering into interest rate hedging contracts. The Company does not hold or issue derivative financial instruments for speculative purposes.

        In 2010, the Company entered into interest rate swap contracts as summarized in the table below:

	Notional Amount		Paying			Receiving	Start Date	Expiration Date
Counterparty A	$	25.0		1.67	%	3-Month LIBOR	October 2010	October 2015
Counterparty A	$	25.0		1.65	%	3-Month LIBOR	October 2010	October 2015
Counterparty B	$	25.0		1.59	%	3-Month LIBOR	October 2010	October 2015
Counterparty B	$	25.0		2.14	%	3-Month LIBOR	October 2010	October 2017

        During 2010 and 2011, the Company entered into a series of treasury rate lock contracts with a total notional value of $175.0 million which were settled in February 2011 and October 2011 for a net pre-tax loss of $0.7 million. These contracts were intended to hedge the risks associated with changes in interest rates on a fixed-rate debt issuance that is anticipated to occur prior to the end of the second quarter of 2012. The net loss on these contracts is reflected as a component of Other comprehensive income.

        The Company's derivative contracts contain provisions that may require the Company or the counterparties to post collateral based upon the current fair value of the derivative contracts. As of

20

AFFILIATED MANAGERS GROUP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

March 31, 2012, the Company had posted collateral of $3.9 million related to its interest rate swap contracts.

        The Company records all derivative instruments on the balance sheet at fair value. As cash flow hedges, the effective portion of the unrealized gain or loss on the derivative instruments is recorded in accumulated other comprehensive income as a separate component of stockholders' equity. Hedge effectiveness is measured by comparing the present value of the cumulative change in the expected future variable cash flows of the hedged contract with the present value of the cumulative change in the expected future variable cash flows of the hedged item. To the extent that the critical terms of the hedged item and the derivative are not identical, hedge ineffectiveness would be reported in earnings as Interest expense. Hedge ineffectiveness was not material in any periods presented. The Company does not expect to reclassify any material portion of the losses related to these derivative contracts into earnings in the next twelve months.

        The following summarizes the location and amount of derivative instrument gains and losses (before taxes) reported in the Consolidated Statements of Comprehensive Income:

14.   Segment Information

        Management has assessed and determined that the Company operates in three business segments representing the Company's three principal distribution channels: Mutual Fund, Institutional and High Net Worth, each of which has different client relationships.

21

AFFILIATED MANAGERS GROUP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

        Revenue in the Mutual Fund distribution channel is earned from advisory and sub-advisory relationships with all domestically-registered investment products as well as non-institutional investment products that are registered abroad. Revenue in the Institutional distribution channel is earned from relationships with public and private client entities, including pension plans, foundations and endowments. Revenue in the High Net Worth distribution channel is earned from relationships with wealthy individuals, family trusts and managed account programs.

        Revenue earned from client relationships managed by Affiliates accounted for under the equity method is not consolidated with the Company's reported Revenue but instead is included (net of operating expenses, including amortization) in Income from equity method investments, and reported in the distribution channel in which the Affiliate operates. Income tax attributable to the profits of the Company's equity method Affiliates is reported within the Company's consolidated income tax provision.

        In firms with revenue sharing arrangements, a certain percentage of revenue is allocated for use by management of an Affiliate in paying operating expenses of that Affiliate, including salaries and bonuses, and is called an "Operating Allocation." In reporting segment operating expenses, Affiliate expenses are allocated to a particular segment on a pro rata basis with respect to the revenue generated by that Affiliate in such segment. Generally, as revenue increases, additional compensation is typically paid to Affiliate management partners from the Operating Allocation. As a result, the contractual expense allocation pursuant to a revenue sharing arrangement may result in the characterization of any growth in profit margin beyond the Company's Owners' Allocation as an operating expense. All other operating expenses (excluding intangible amortization) and interest expense have been allocated to segments based on the proportion of cash flow distributions reported by Affiliates in each segment.

Balance as of March 31, 2012	$	971.6	$	(338.7	)	$	632.9		$	665.9		$	1,298.8

        During the three months ended March 31, 2012, the Company determined that the fair value of the indefinite-lived intangible assets at one of its Affiliates, a manager of growth-oriented U.S. equity mutual funds, had declined below its carrying value and, accordingly, reduced the carrying value by $8.7 million to its fair value ($131.7 million). The fair value of these indefinite-lived assets was calculated using a discounted cash flow analysis, a Level 3 fair value measurement. The significant assumptions used in the valuation were a weighted average annual growth rate of approximately 3.0% and a discount rate of 16.0%. This impairment has been presented within Amortization of intangible assets in the Consolidated Statements of Income. During the second quarter of 2012, this Affiliate has experienced ongoing client redemptions, and the Company believes an additional impairment is likely in the second quarter of 2012.

        For the Company's Affiliates that are consolidated, definite-lived acquired client relationships are amortized over their expected useful lives. As of March 31, 2012, these relationships were being amortized over a weighted average life of approximately ten years. Amortization expense for these relationships was $22.1 million for the three months ended March 31, 2011 as compared to $21.7 million for the three months ended March 31, 2012. The Company estimates that its consolidated annual amortization expense will be approximately $90.0 million for the next five years, assuming no additional investments in new or existing Affiliates.

Equity Method

        The definite-lived acquired client relationships attributable to the Company's equity method investments are amortized over their expected useful lives. As of March 31, 2012, these relationships were being amortized over a weighted average life of approximately seven years. Amortization expense

for these relationships was $8.4 million for the three months ended March 31, 2011 as compared to $8.2 million for the three months ended March 31, 2012. Assuming no additional investments in new or existing Affiliates, the Company estimates the annual amortization expense attributable to its current equity-method Affiliates for the next five years as follows:

Year Ending December 31,	Estimated Amortization Expense
2012	$	32.7
2013		32.7
2014		11.2
2015		2.7
2016		0.2

16.   Affiliate Equity

        The Company periodically issues Affiliate equity interests to and repurchases Affiliate equity interests from its Affiliate partners. In these transactions, if the equity is issued for consideration below the fair value of the equity or repurchased for consideration above the fair value of the equity, then such difference is recorded as compensation expense over the requisite service period. The Company recognized compensation expense related to Affiliate equity of $5.2 million ($3.5 million attributable to the controlling interest) for the three months ended March 31, 2011 as compared to $6.3 million ($2.2 million attributable to the controlling interest) for the three months ended March 31, 2012.

        Many of the Company's operating agreements provide the Company a conditional right to call and Affiliate partners the conditional right to put their retained equity interests at certain intervals. The purchase price of these conditional purchases are generally calculated based upon a multiple of the Affiliate's cash flow distributions, which is intended to represent fair value. Affiliate management partners are also permitted to sell their equity interests to other individuals or entities in certain cases, subject to the Company's approval or other restrictions. The Company, at its option, may pay for Affiliate equity purchases in cash, shares of its common stock or other forms of consideration and can consent to the transfer of these interests to other individuals or entities.

        The current redemption value of these interests has been presented as Redeemable non-controlling interests on the Company's Consolidated Balance Sheets. Changes in the current redemption value are recorded to Additional paid-in capital. The following table presents the changes in Redeemable non-controlling interests during the period:

Balance as of January 1, 2012	$	451.8
Issuance of Redeemable non-controlling interest		7.0
Repurchase of Redeemable non-controlling interest		(11.2	)
Changes in redemption value		62.0
Balance as of March 31, 2012	$	509.6

Item 2.    Management's Discussion and Analysis of Financial Condition and Results of Operations

Forward-Looking Statements

When used in this Quarterly Report on Form 10-Q, in our other filings with the United States Securities and Exchange Commission, in our press releases and in oral statements made with the approval of an executive officer, the words or phrases "will likely result," "are expected to," "will continue," "is anticipated," "may," "intends," "believes," "estimate," "project" or similar expressions are intended to identify "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements are subject to certain risks and uncertainties, including, among others, the following:

•

our performance is directly affected by changing conditions in global financial markets generally and in the equity markets particularly, and a decline or a lack of sustained growth in these markets may result in decreased advisory fees or performance fees and a corresponding decline (or lack of growth) in our operating results and in the cash flow distributable to us from our Affiliates;

•

we cannot be certain that we will be successful in finding or investing in additional investment management firms on favorable terms, that we will be able to consummate announced investments in new investment management firms, or that existing and new Affiliates will have favorable operating results;

•

we may need to raise capital by making long-term or short-term borrowings or by selling shares of our common stock or other securities in order to finance investments in additional investment management firms or additional investments in our existing Affiliates, and we cannot be sure that such capital will be available to us on acceptable terms, if at all; and

•

those certain other factors discussed under the caption "Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2011, and in any other filings we make with the Securities and Exchange Commission from time to time.

These factors (among others) could affect our financial performance and cause actual results to differ materially from historical earnings and those presently anticipated and projected. We will not undertake and we specifically disclaim any obligation to release publicly the result of any revisions which may be made to any forward-looking statements to reflect events or circumstances after the date of such statements or to reflect the occurrence of events, whether or not anticipated. In that respect, we wish to caution readers not to place undue reliance on any such forward-looking statements, which speak only as of the date made.

        Management's Discussion and Analysis should be read in conjunction with the Consolidated Financial Statements of AMG and its subsidiaries (collectively, the "Company" or "AMG") and the notes thereto contained elsewhere in this Quarterly Report on Form 10-Q.

Executive Overview

        We are a global asset management company with equity investments in leading boutique investment management firms (our "Affiliates"). Our innovative partnership approach allows each Affiliate's management team to own significant equity in their firm while maintaining operational autonomy. Our strategy is to generate growth through the internal growth of existing Affiliates, as well as through investments in new Affiliates. In addition, we provide centralized assistance to our Affiliates in strategic matters, marketing, distribution, product development and operations.

        As of March 31, 2012, we manage approximately $363.9 billion in assets through our Affiliates in more than 350 investment products across a broad range of asset classes and investment styles in three principal distribution channels: Mutual Fund, Institutional and High Net Worth. We believe that our diversification across asset classes, investment styles and distribution channels helps to mitigate our

28

exposure to the risks created by changing market environments. The following summarizes our operations in our three principal distribution channels.

•

In the Mutual Fund distribution channel, our Affiliates provide advisory or sub-advisory services to mutual funds. These funds are distributed to retail and institutional clients directly and through intermediaries, including independent investment advisors, retirement plan sponsors, broker-dealers, major fund marketplaces and bank trust departments.

•

In the Institutional distribution channel, we offer a broad range of investment styles, including small, small/mid, mid and large capitalization value, growth equity and emerging markets. In addition, our Affiliates offer quantitative, alternative and fixed income products. Through this distribution channel, our Affiliates manage assets for public and private client entities, including pension plans, foundations and endowments, with disciplined and focused investment styles that address the specialized needs of institutional clients.

•

The High Net Worth distribution channel is comprised broadly of two principal client groups. The first group consists principally of direct relationships with high net worth individuals and families and charitable foundations. For these clients, our Affiliates provide investment management or customized investment counseling and fiduciary services. The second group consists of individual managed account client relationships established through intermediaries, which are generally brokerage firms or other sponsors. Our Affiliates provide investment management services through more than 100 managed account and wrap programs. In 2011, we formed AMG Wealth Partners to extend and tailor our innovative partnership approach to investments in boutique wealth management firms.

Pending Investments

        In March 2012, AMG Wealth Partners announced an agreement to purchase an equity interest in Veritable, LP ("Veritable"). Veritable manages $11.1 billion in assets for ultra-high net worth individuals. Subject to customary closing conditions, regulatory approvals and compliance with other terms of the purchase agreement, we anticipate that AMG Wealth Partners' investment in Veritable will close in the second quarter of 2012.

        In April 2012, we announced an agreement to purchase Yacktman Asset Management Co. ("Yacktman"). Yacktman manages $16.8 billion of assets, specializing in large-cap equities through a value-oriented approach. Subject to customary closing conditions, regulatory approvals and compliance with other terms of the purchase agreement, we anticipate that our investment in Yacktman will close in the third quarter of 2012.

Our Structure and Relationship with Affiliates

        In making investments in boutique investment management firms, we seek to partner with the highest quality firms in the industry, with outstanding management teams, strong long-term performance records and a demonstrated commitment to continued growth and success. Fundamental to our investment approach is the belief that Affiliate management equity ownership (along with AMG's ownership) aligns our interests and provides Affiliate managers with a powerful incentive to continue to grow their business. Our investment structure provides a degree of liquidity and diversification to principal owners of boutique investment management firms, while at the same time expanding equity ownership opportunities among the firm's management and allowing management to continue to participate in the firm's future growth. Our partnership approach also ensures that Affiliates maintain operational autonomy in managing their business, thereby preserving their firm's entrepreneurial culture and independence.

29

        Although the specific structure of each investment is highly tailored to meet the needs of a particular Affiliate, in all cases, we establish a meaningful equity interest in the firm, with the remaining equity interests retained by the management of the Affiliate. Each Affiliate is organized as a separate firm, and its operating or shareholder agreement is structured to provide appropriate incentives for Affiliate management owners and to address the Affiliate's particular characteristics while also enabling us to protect our interests, including through arrangements such as long-term employment agreements with key members of the firm's management team.

        In most cases, we own a majority of the equity interests of a firm and structure a revenue sharing arrangement, in which a percentage of revenue is allocated for use by management of that Affiliate in paying operating expenses of the Affiliate, including salaries and bonuses. We call this the "Operating Allocation." The portion of each Affiliate's revenue that is allocated to the owners of that Affiliate (including us) is called the "Owners' Allocation." Each Affiliate allocates its Owners' Allocation to its managers and to us generally in proportion to their and our respective ownership interests in that Affiliate.

        One of the purposes of our revenue sharing arrangements is to provide ongoing incentives for Affiliate managers by allowing them to participate in the growth of their firm's revenue, which may increase their compensation from both the Operating Allocation and the Owners' Allocation. These arrangements also provide incentives to control operating expenses, thereby increasing the portion of the Operating Allocation that is available for growth initiatives and compensation.

        An Affiliate's Operating Allocation is structured to cover its operating expenses. However, should actual operating expenses exceed the Operating Allocation, our contractual share of cash under the Owners' Allocation generally has priority over the allocations and distributions to the Affiliate's managers. As a result, the excess expenses first reduce the portion of the Owners' Allocation allocated to the Affiliate's managers until that portion is eliminated, before reducing the portion allocated to us. Any such reduction in our portion of the Owners' Allocation is required to be paid back to us out of the portion of future Owners' Allocation allocated to the Affiliate's managers.

        Our minority investments are also structured to align our interests with those of the Affiliate's management through shared equity ownership, as well as to preserve the Affiliate's entrepreneurial culture and independence by maintaining the Affiliate's operational autonomy. In cases where we hold a minority investment, the revenue sharing arrangement generally allocates a percentage of the Affiliate's revenue to us. The remaining revenue is used to pay operating expenses and profit distributions to the other owners. Generally where we own a minority investment, we are required to use the equity method of accounting. Consistent with this method, we have not consolidated the operating results of these firms (including their revenue) in our Consolidated Statements of Income. Our share of these firms' profits (net of intangible amortization) is reported in Income from equity method investments, and is therefore reflected in our Net income and EBITDA. As a consequence, increases or decreases in these firms' assets under management ($100.2 billion as of March 31, 2012 and included in our reported assets under management) will not affect our reported revenue.

        Certain of our Affiliates operate under profit-based arrangements through which we own a majority of the equity in the firm and receive a share of profits as cash flow, rather than a percentage of revenue through a typical revenue sharing agreement. As a result, we participate fully in any increase or decrease in the revenue or expenses of such firms. In these cases, we participate in a budgeting process and generally provide incentives to management through compensation arrangements based on the performance of the Affiliate.

        We are focused on establishing and maintaining long-term partnerships with our Affiliates. Our shared equity ownership gives both us and our Affiliates meaningful incentives to manage their businesses for strong future growth. From time to time, we may consider changes to the structure of our relationship with an Affiliate in order to better support the firm's growth strategy.

EBITDA, including a reconciliation to cash flow from operations, is discussed in greater detail in "Supplemental Liquidity Measure" on page 39.

        During the twelve months ended March 31, 2012, the MSCI EAFE decreased 5.3% while the S&P 500 increased 8.5%. Our total assets under management grew to $363.9 billion at March 31, 2012, an increase of approximately 7% over March 31, 2011. The growth in our assets under management was primarily the result of organic growth of our Affiliates from net client cash flows ($23.5 billion).

Diversification of Assets under Management

        The following table provides information regarding the composition of our assets under management:

	December 31, 2011					March 31, 2012
(in billions)	Assets under Management		Percentage of Total			Assets under Management		Percentage of Total

The Equity asset class includes equity, balanced and asset allocation products.

(2)

The Alternative asset class includes private equity, multi-strategy, market neutral equity and hedge products.

31

(3)

Our Affiliates currently sponsor money market funds with fund assets representing less than 1% of our assets under management.

(4)

Investments in sovereign and non-sovereign debt of European countries represent less than 1% of our assets under management.

(5)

The Geography of a particular investment product describes the general location of its investment holdings.

        Our assets under management increased during the three months ended March 31, 2012 principally as a result of positive investment performance in all asset classes and organic growth from net client cash flows in our Alternative asset class ($6.0 billion). Our assets under management also increased from positive investment performance across all geographic regions and organic growth from net client cash flows in Global/International ($7.0 billion).

Assets under Management by Operating Segment

        The following table presents our Affiliates' reported assets under management by operating segment (which are also referred to as distribution channels in this Quarterly Report on Form 10-Q).

Statement of Changes-Quarter to Date

(in billions)	Mutual Fund			Institutional			High Net Worth			Total
December 31, 2011	$	85.2		$	205.7		$	36.6		$	327.5
Client cash inflows		6.2			12.3			2.6			21.1
Client cash outflows		(4.8	)		(7.3	)		(1.9	)		(14.0	)
Net client cash flows		1.4			5.0			0.7			7.1
Investment performance		8.5			17.1			3.7			29.3
March 31, 2012	$	95.1		$	227.8		$	41.0		$	363.9

        As shown in the assets under management table above, client cash inflows totaled $21.1 billion while client cash outflows totaled $14.0 billion for the three months ended March 31, 2012. The net flows for the three months ended March 31, 2012 occurred across a broad range of product offerings in each of our distribution channels, with no individual cash inflow or outflow having a material impact on our revenue or expenses.

        The operating segment analysis presented in the following table is based on average assets under management. For the Mutual Fund distribution channel, average assets under management represent an average of the daily net assets under management. For the Institutional and High Net Worth distribution channels, average assets under management reflect the billing patterns of particular client accounts. For example, assets under management for an account that bills in advance is presented in the table on the basis of beginning of period assets under management while an account that bills in arrears is reflected on the basis of end of period assets under management. We believe that this

32

analysis more closely correlates to the billing cycle of each distribution channel and, as such, provides a more meaningful relationship to revenue.

In 2012, we changed our estimate of payments to be made under certain of our contingent payment arrangements and recognized a gain totaling $9.9 million ($5.0 million attributable to the controlling interest). This gain was allocated $9.3 million, $0.5 million and $0.1 million to our Mutual Fund, Institutional and High Net Worth channels, respectively.

(3)

During 2012, we recorded an $8.7 million expense associated with the revaluation of indefinite-lived intangible assets.

Results of Operations

Revenue

        Our revenue is generally determined by the level of our assets under management, the portion of our assets across our products and three operating segments, which realize different fee rates, and the recognition of any performance fees. Performance fees are generally measured on absolute or relative investment performance against a benchmark. As a result, the level of performance fees earned can vary significantly from period to period and these fees may not necessarily be correlated to changes in total assets under management.

        Our total revenue decreased $8.6 million (or 2%) in the three months ended March 31, 2012, as compared to the three months ended March 31, 2011, primarily from a modest decline in our average fee rates and a decline in performance fees ($1.9 million), partially offset by a 1% increase in average assets under management from our consolidated Affiliates. The increase in average assets under management and the changes in the composition of our assets under management between operating segments did not have a significant impact on our results.

        The following discusses the changes in our revenue by operating segment.

Mutual Fund Distribution Channel

        The decrease in revenue of $8.5 million (or 5%) in the Mutual Fund distribution channel in the three months ended March 31, 2012 as compared to the three months ended March 31, 2011, resulted primarily from a 4% decrease in average assets under management from our consolidated Affiliates. The decrease in average assets under management resulted principally from net client cash flows at our consolidated Affiliates, partially offset by positive investment performance.

Institutional Distribution Channel

        Revenue in the Institutional distribution channel remained relatively flat in the three months ended March 31, 2012 as compared to the three months ended March 31, 2011, primarily from a 3% increase in average assets under management from our consolidated Affiliates, offset by a decline in performance fees. The increase in average assets under management resulted principally from net client cash flows and positive investment performance. Unrelated to the change in assets under management, consolidated performance fee revenue decreased $1.8 million to $2.2 million for the three months ended March 31, 2012 as compared to the three months ended March 31, 2011.

High Net Worth Distribution Channel

        Revenue in the High Net Worth distribution channel remained relatively flat in the three months ended March 31, 2012 as compared to the three months ended March 31, 2011, primarily from a 4% increase in average assets under management from our consolidated Affiliates offset by a modest decline in our average fee rates. The increase in average assets under management resulted principally from net client cash flows and positive investment performance.

34

Operating Expenses

        The following table summarizes our consolidated operating expenses:

	For the Three Months Ended March 31,
					% Change
(in millions)	2011		2012
Compensation and related expenses	$	179.5	$	181.1	1  %
Selling, general and administrative		87.5		85.0	(3)%
Amortization of intangible assets		22.1		30.4	38  %
Depreciation and other amortization		3.8		3.4	(11)%
Other operating expenses		8.5		9.0	6  %
Total operating expenses	$	301.4	$	308.9	2  %

        The substantial portion of our operating expenses is incurred by our Affiliates, the majority of which is incurred by Affiliates with revenue sharing arrangements. For Affiliates with revenue sharing arrangements, an Affiliate's Operating Allocation percentage generally determines its operating expenses. Accordingly, our compensation expense is generally impacted by increases or decreases in each Affiliate's revenue and the corresponding increases or decreases in their respective Operating Allocations. During the three months ended March 31, 2012, approximately $89.9 million, or about 49.6% of our consolidated compensation expense, was attributable to our Affiliate partners from their Operating Allocations. The percentage of revenue allocated to operating expenses varies from one Affiliate to another and may vary within an Affiliate depending on the source or amount of revenue. As a result, changes in our aggregate revenue may not impact our consolidated operating expenses to the same degree.

        Compensation and related expenses increased $1.6 million (or 1%) in the three months ended March 31, 2012, as compared to the three months ended March 31, 2011. This increase was attributable to a $3.2 million increase in costs associated with our global distribution initiatives and was partially offset by a decrease in compensation resulting from the relationship between revenue and operating expenses at Affiliates which experienced decreases in revenue, and accordingly, reported lower compensation expenses.

        Selling, general and administrative expenses decreased $2.5 million (or 3%) in the three months ended March 31, 2012 as compared to the three months ended March 31, 2011. This decrease resulted primarily from decreases in sub-advisory and distribution expenses attributable to a decrease in assets under management at our Affiliates in the Mutual Fund distribution channel.

        Amortization of intangible assets increased $8.3 million (or 38%) in the three months ended March 31, 2012, as compared to the three months ended March 31, 2011. This increase was the result of an $8.7 million expense associated with the revaluation of indefinite-lived intangible assets at one of our Affiliates.

        Depreciation and other amortization decreased $0.4 million (or 11%) in the three months ended March 31, 2012, as compared to the three months ended March 31, 2011, principally related to a decrease in spending on depreciable assets in recent periods.

        Other operating expenses increased $0.5 million (or 6%) in the three months ended March 31, 2012, as compared to the three months ended March 31, 2011. This increase was principally attributable to an increase in costs associated with our global distribution initiatives.

        Income from equity method investments consists of our share of income from Affiliates that are accounted for under the equity method of accounting, net of any related intangible amortization. Income from equity method investments increased $4.3 million (or 42%) in the three months ended March 31, 2012 as compared to the three months ended March 31, 2011. This increase is principally as a result of increases in revenue resulting from higher assets under management.

        Investment and other income increased $1.7 million (or 20%) in the three months ended March 31, 2012 as compared to the three months ended March 31, 2011. This increase is primarily the result of an increase in Affiliate investment earnings.

        Interest expense decreased $0.8 million (or 4%) in the three months ended March 31, 2012 as compared to the three months ended March 31, 2011, principally attributable to $0.8 million in issuance costs related to the credit facility amendment that occurred in the three months ended March 31, 2011.

        Imputed interest expense and contingent payment arrangements consists of interest accretion on our senior convertible securities and our junior convertible trust preferred securities, as well as the accretion and revaluation of our contingent payment arrangements. Imputed interest expense and contingent payment arrangements decreased $10.8 million in the three months ended March 31, 2012 as compared to the three months ended March 31, 2011, principally as a result of a $9.9 million gain on revaluation of contingent payment arrangements.

        Income taxes decreased $2.1 million (or 8%) in the three months ended March 31, 2012 as compared to the three months ended March 31, 2011 as the result of a decrease in Income before income taxes for controlling interests.

Net Income

        The following table summarizes Net income:

	For the Three Months Ended March 31,
					% Change
(in millions)	2011		2012
Net income	$	89.4	$	93.0	4  %
Net income (non-controlling interests)		50.3		55.6	11  %
Net income (controlling interest)		39.1		37.4	(4)%

36

        Net income attributable to non-controlling interests increased $5.3 million (or 11%) in the three months ended March 31, 2012 as compared to the three months ended March 31, 2011. This change resulted principally from the $4.9 million gain on revaluation of contingent payment arrangements as well as increases in Affiliate investment earnings. These increases were offset by previously discussed decreases in revenue.

        Net income (controlling interest) decreased $1.7 million (or 4%) in the three months ended March 31, 2012 as compared to the three months ended March 31, 2011 as a result of the previously discussed decreases in revenue as well as increases in reported operating expenses, partially offset by the $5.0 million gain on revaluation of contingent payment arrangements.

Supplemental Performance Measures

        As supplemental information, we provide non-GAAP performance measures that we refer to as Economic net income and Economic earnings per share. We consider Economic net income an important measure of our financial performance, as we believe it best represents our operating performance before non-cash expenses relating to our acquisition of interests in our investment management firms. Economic net income and Economic earnings per share are used by our management and Board of Directors as our principal performance benchmarks, including as measures for aligning executive compensation with stockholder value. These measures are provided in addition to, but not as a substitute for, Net income (controlling interest) and Earnings per share. Economic net income and Economic earnings per share are not liquidity measures and should not be used in place of any liquidity measure calculated under accounting principles generally accepted in the United States ("GAAP").

        Under our Economic net income definition, we add to Net income (controlling interest) amortization (including equity method amortization and reductions in the carrying value of our intangible assets), deferred taxes related to intangible assets, non-cash imputed interest expense (principally related to the accounting for convertible securities and contingent payment arrangements) and Affiliate equity expense. We add back amortization attributable to acquired client relationships because this expense does not correspond to the changes in value of these assets, which do not diminish predictably over time. The portion of deferred taxes generally attributable to intangible assets (including goodwill) that we no longer amortize but which continues to generate tax deductions is added back, because we believe it is unlikely these accruals will be used to settle material tax obligations. We add back non-cash expenses relating to certain transfers of equity between Affiliate management partners, when these transfers have no dilutive effect to our shareholders.

        Economic earnings per share represents Economic net income divided by the adjusted diluted average shares outstanding, which measures the potential share issuance from our senior convertible securities and junior convertible securities (each further described in Liquidity and Capital Resources) using a "treasury stock" method. Under this method, only the net number of shares of common stock equal to the value of these securities in excess of par, if any, are deemed to be outstanding. We believe the inclusion of net shares under a treasury stock method best reflects the benefit of the increase in available capital resources (which could be used to repurchase shares of common stock) that occurs when these securities are converted and we are relieved of our debt obligation. This method does not take into account any increase or decrease in our cost of capital in an assumed conversion.

(1)

We are required to use the equity method of accounting for certain of our investments and, as such, do not separately report these Affiliates' revenues or expenses (including intangible amortization) in our income statement. Our share of these investments' amortization, $8.4 million and $8.2 million for the three months ended March 31, 2011 and 2012, respectively, is reported in Income from equity method investments.

(2)

Our reported intangible amortization, $22.1 million and $30.4 million for the three months ended March 31, 2011 and 2012, respectively, includes $3.4 million and $3.6 million, respectively, of amortization attributable to our non-controlling interests, amounts not added back to Net income (controlling interest) to measure our Economic net income. The reported intangible amortization for the three months ended March 31, 2012 includes an $8.7 million expense associated with the revaluation of indefinite-lived intangible assets at one of our Affiliates.

(3)

As described in Note (2) above, we reduced the carrying value of certain of our indefinite-lived intangible assets during the three months ended March 31, 2012 which resulted in a $3.3 million decrease in our intangible-related deferred taxes.

(4)

Our reported Imputed interest expense and contingent payment arrangements, $8.3 million and ($2.5) million for the three months ended March 31, 2011 and 2012, respectively, includes $1.4 million and ($3.5) million of imputed interest attributable to our non-controlling interests, amounts not added back to Net income (controlling interest) to measure our Economic net income.

Liquidity and Capital Resources

        The following table summarizes certain key financial data relating to our liquidity and capital resources:

(in millions)	December 31, 2011		March 31, 2012
Balance Sheet Data
Cash and cash equivalents	$	449.5	$	393.7
Senior bank debt		250.0		250.0
2008 senior convertible notes		435.6		439.2
Junior convertible trust preferred securities		512.6		513.3

	For the Three Months Ended March 31,
	2011			2012
Cash Flow Data
Operating cash flow	$	128.3		$	52.5
Investing cash flow		(11.3	)		2.1
Financing cash flow		(179.7	)		(113.2	)
EBITDA(1)		118.2			114.1

(1)

The definition of EBITDA is presented below under "Supplemental Liquidity Measure".

        We view our ratio of debt to EBITDA (our "internal leverage ratio") as an important gauge of our ability to service debt, make new investments and access additional capital. Consistent with industry practice, we do not consider junior trust preferred securities as debt for the purpose of determining our internal leverage ratio. We also view our leverage on a "net debt" basis by deducting from our debt balance holding company cash. At March 31, 2012, our internal leverage ratio was 1.1:1.

        Under the terms of our credit facility we are required to meet two financial ratio covenants. The first of these covenants is a maximum ratio of debt to EBITDA (the "bank leverage ratio") of 3.0. The calculation of our bank leverage ratio is generally consistent with our internal leverage ratio approach. The second covenant is a minimum EBITDA to cash interest expense ratio of 3.0 (our "bank interest coverage ratio"). For purposes of calculating these ratios, share-based compensation expense is added back to EBITDA. As of March 31, 2012, our actual bank leverage and bank interest coverage ratios were 1.5 and 8.1, respectively, and we were in compliance with all terms of our credit facility. We have $750.0 million of remaining capacity under our credit facility and we could borrow the entire amount and remain in compliance with our credit agreement.

        We are rated BBB- by both Standard & Poor's and Fitch rating agencies. With the exception of a modest increase in the borrowing rate under our credit facility (0.50%), a downgrade of our credit rating would have no direct financial effect on any of our agreements or securities (or otherwise trigger a default).

Supplemental Liquidity Measure

        As supplemental information, we have provided information regarding our EBITDA, a non-GAAP liquidity measure. This measure is provided in addition to, but not as a substitute for, cash flow from operating activities. EBITDA represents earnings before interest expense, income taxes, depreciation and amortization. EBITDA, as calculated by us, may not be consistent with computations of EBITDA by other companies. As a measure of liquidity, we believe that EBITDA is useful as an indicator of our ability to service debt, make new investments and meet working capital requirements. We further believe that many investors use this information when analyzing the financial position of companies in the investment management industry.

        The following table provides a reconciliation of cash flow from operations to EBITDA:

	For the Three Months Ended March 31,
(in millions)	2011			2012
Cash flow from operating activities	$	128.3		$	52.5
Interest expense, net of non-cash items(1)		16.8			16.8

Other non-cash adjustments(3)		(13.9	)		(7.6	)
EBITDA	$	118.2		$	114.1

(1)

Non-cash items include Amortization of issuance costs and Imputed interest and contingent payment arrangements ($10.9 million and ($0.7) million for the three months ended March 31, 2011 and 2012, respectively).

(2)

Distributions from equity method investments were $64.9 million and $36.8 million for the three months ended March 31, 2011 and 2012, respectively.

(3)

Other non-cash adjustments include share-based compensation expense, tax benefits from stock options and other adjustments to reconcile Net income (controlling interest) to net cash flow from operating activities.

        In the three months ended March 31, 2012, we met our cash requirements primarily through cash generated by operating activities. Our principal uses of cash were to make distributions to Affiliate partners and repay our other liabilities. We expect that our principal uses of cash for the foreseeable future will be for investments in new and existing Affiliates, distributions to Affiliate partners, payment of principal and interest on outstanding debt, and for working capital purposes.

        The following table summarizes the principal amount due at maturity of our debt obligations and convertible securities as of March 31, 2012:

(in millions)	Amount		Maturity Date		Form of Repayment
Senior bank debt	$	250.0		2016		(1	)
2008 senior convertibles notes		460.0		2038		(2	)
Junior convertible trust preferred securities		730.8		2036/2037		(3	)

Settled in cash or common stock (or a combination thereof) at our election if the holders exercise their conversion rights.

Senior Bank Debt

        We entered into a $1.0 billion senior unsecured credit facility in November 2011 (the "credit facility"), consisting of a $750.0 million revolving credit facility (the "revolver") and a $250.0 million term loan (the "term loan"), the principal terms of which are similar to our previous senior unsecured

40

revolving credit facility. The term loan and $720.0 million of the revolver have a five-year maturity (maturing November 3, 2016); the remaining $30.0 million of the revolver matures January 12, 2015. Subject to certain conditions, we may increase the revolver and the term loan by up to $150.0 million and $250.0 million, respectively. The term loan borrowings were used to repay the outstanding balance under the previous revolving credit facility ($210.0 million) and for general corporate purposes.

        The credit facility is unsecured and contains financial covenants with respect to leverage and interest coverage, as well as customary affirmative and negative covenants, including limitations on indebtedness, liens, cash dividends, asset dispositions and fundamental corporate changes.

Convertible Securities

        At March 31, 2012, we have one senior convertible security outstanding ("2008 senior convertible notes") and two junior convertible trust preferred securities outstanding, one issued in 2006 (the "2006 junior convertible trust preferred securities") and a second issued in 2007 (the "2007 junior convertible trust preferred securities"). The principal terms of these securities are summarized below.

	2008 Senior Convertible Notes		2007 Junior Convertible Trust Preferred Securities		2006 Junior Convertible Trust Preferred Securities
Issue date	August 2008		October 2007		April 2006

Coupon frequency	Semi-annually		Quarterly		Quarterly
Tax deduction rate(2)	9.38	%	8.00	%	7.50	%

(1)

The carrying value is accreted to the principal amount at maturity over an expected life of five years for the 2008 senior convertible notes and 30 years for each of the junior convertible trust preferred securities.

(2)

These convertible securities are considered contingent payment debt instruments under federal income tax regulations, which require us to deduct interest in an amount greater than our reported Interest expense.

Derivative Instruments

        From time to time, we seek to offset our exposure to changing interest rates under our debt financing arrangements by entering into interest rate hedging contracts. These instruments are designated as cash flow hedges with changes in fair value recorded in Other comprehensive income for the effective portion of the hedge.

        We have entered into interest rate swap contracts to exchange a fixed rate for the variable rate on a portion of our credit facility. These contracts expire between 2015 and 2017. Under these contracts, we will pay a weighted average fixed rate of 1.76% on a notional amount of $100.0 million through October 2015. Thereafter, through October 2017, we will pay a weighted average fixed rate of 2.14% on a remaining notional amount of $25.0 million. As of March 31, 2012, the unrealized loss (before taxes) on these contracts was $3.0 million.

41

        We also entered into treasury rate lock agreements to hedge an anticipated issuance of fixed-rate debt. Treasury lock contracts with a total notional value of $175.0 million were settled in February 2011 and October 2011 for a net pre-tax loss of $0.7 million. These contracts were intended to hedge the risks associated with changes in interest rates on fixed-rate debt issuance that is anticipated to occur prior to the end of the second quarter of 2012. The net loss on these contracts is reflected as a component of Other comprehensive income.

Forward Equity Sale Agreement

        In July 2011, we entered into a forward equity sale agreement with two major securities firms under which we may sell shares of our common stock with an aggregate sales price of up to $300.0 million. This agreement replaced all then outstanding forward equity sale agreements. As of March 31, 2012, no forward equity sales have occurred.

Affiliate Equity

        Many of our operating agreements provide us a conditional right to call and Affiliate partners the conditional right to put their retained equity interests at certain intervals. The purchase price of these conditional purchases are generally calculated based upon a multiple of the Affiliate's cash flow distributions, which is intended to represent fair value. Affiliate management partners are also permitted to sell their equity interests to other individuals or entities in certain cases, subject to our approval or other restrictions.

        Our current redemption value for these interests has been presented as Redeemable non-controlling interests on our Consolidated Balance Sheets. Although the timing and amounts of these purchases are difficult to predict, we expect to repurchase approximately $50.0 million of Affiliate equity during 2012, and, in such event, will own the cash flow associated with any equity repurchased.

Operating Cash Flow

        Cash flow from operations generally represents Net income plus non-cash charges for amortization, deferred taxes, equity-based compensation and depreciation, as well as increases and decreases in our consolidated working capital.

        The decrease in cash flows from operations for the three months ended March 31, 2012 as compared to the three months ended March 31, 2011 resulted principally from decreases in distributions received from equity method investments of $28.1 million and decreases in the collections of Investment advisory fees receivable of $15.5 million, as well as increases in settlements of Accounts payable and accrued liabilities of $25.5 million.

Investing Cash Flow

        The net cash flow from investing activities increased $13.4 million for the three months ended March 31, 2012 as compared to the three months ended March 31, 2011. This was primarily the result of our Affiliate investments during the three months ended March 31, 2011.

        We plan to close our investments in Veritable through our subsidiary, AMG Wealth Partners, and Yacktman in the second and third quarter of 2012, respectively. Both transactions will be financed with existing cash and borrowings under our credit facility.

Financing Cash Flow

        Financing cash flows increased $66.5 million for the three months ended March 31, 2012 as compared to the three months ended March 31, 2011. This was primarily a result of a decrease in repayments of bank debt of $120.0 million, an increase in the repurchase of common stock of $32.7 million, an increase in distributions to non-controlling interests of $13.4 million, as well as an increase in repurchases of Affiliate equity of $9.1 million.

42

        Excess tax benefits associated with stock options have been reported as financing cash flows in the amount of $3.5 million and $4.9 million as of March 31, 2012 and 2011, respectively.

        Under past acquisition agreements, we are contingently liable, upon achievement of specified financial targets, to make payments of up to $496.3 million through 2017. In 2012, we expect to make total payments of approximately $72.0 million to settle portions of these contingent arrangements. In addition, we expect to repurchase approximately $50.0 million of interests in certain existing Affiliates in 2012.

        Our Board of Directors has periodically authorized share repurchase programs (most recently October 2011). The maximum number of shares that may be repurchased under outstanding programs is approximately 2.5 million. The timing and amount of repurchases are determined at the discretion of our management. In the three months ended March 31, 2012, we repurchased 0.3 million shares for $36.1 million at an average price per share of $107.65.

        We anticipate that borrowings under the credit facility and proceeds from the settlement of any forward equity sales, together with cash flows from operations will be sufficient to support our cash flow needs for the foreseeable future.

Contractual Obligations

        The following table summarizes our contractual obligations as of March 31, 2012:

			Payments Due

(1)

The timing of debt payments assumes that outstanding debt is settled for cash or common stock at the applicable maturity dates. The amounts include the cash payment of fixed interest. Holders of the 2008 convertible notes may put their interests to us for $460.0 million in 2013.

(2)

Other liabilities reflect amounts payable to Affiliate managers related to our purchase of additional Affiliate equity interests and deferred purchase price payments for acquisitions. This table does not include liabilities for uncertain tax positions or commitments to co-invest in certain investment partnerships (of $21.8 million and $80.6 million as of March 31, 2012, respectively) as we cannot predict when such obligations will be paid.

(3)

The amount of contingent payments related to business acquisitions disclosed in the table represents our expected settlement amounts. The maximum settlement amount through 2012 is approximately $252.1 million and $244.2 million in periods thereafter.

43

Recent Accounting Developments

        In May 2011, the Financial Accounting Standards Board issued an update to the fair value measurements and disclosures guidance. The new guidance clarifies existing fair value measurement principles and expands certain disclosure requirements, particularly for measurements categorized as Level 3. The amendment is effective for interim and fiscal periods beginning after December 15, 2011. We adopted this guidance in the first quarter of 2012. Adoption of this new guidance did not have a material impact on our Consolidated Financial Statements.

Critical Accounting Estimates and Judgments

Indefinite-Lived Intangible Assets

        Indefinite-lived intangible assets are comprised of investment advisory contracts between our Affiliates and their sponsored registered investment companies. Because the contracts are with the registered investment companies themselves, and not with the underlying investors, and the contracts between our Affiliates and the registered investment companies are typically renewed on an annual basis, industry practice under generally accepted accounting principles is to consider the contract life to be indefinite and, as a result, not amortizable.

        We perform indefinite-lived intangible asset impairment tests annually, or more frequently should circumstances suggest fair value has declined below the related carrying amount. We assess each of our indefinite-lived intangible assets for impairment by comparing their carrying value to the fair value of the investment advisory contract. During the quarter ended March 31, 2012, we determined that the fair value of an indefinite-lived intangible asset at one of our Affiliates, a manager of growth-oriented U.S. equity mutual funds, had declined below its carrying value and, accordingly, we reduced the asset to its current fair value. The fair value of the indefinite-lived intangible assets was determined by discounting the projected future cash flows associated with the underlying mutual fund contracts (such cash flows being dependent upon projected growth). Our discount rates are developed with input from valuation experts. This impairment, which totaled $8.7 million, has been presented within Amortization of intangible assets in our Consolidated Statements of Income. Further declines in the fair value of this asset will likely result in future impairments. For example, if assets under management underlying this asset were to decline 5% (assuming all other factors remain constant), we would likely record an additional impairment of approximately $7.0 million.

Contingent Payment Arrangements

        Imputed interest expense results, in part, from accreting the fair value of our contingent payment obligations to our projected future payment amounts over the expected life of these arrangements, as well as any changes to our estimate of the future payments. The fair value of our contingent payment arrangements is determined by discounting the projected future payments (such estimates being dependent upon projected revenue) using current market rates. Our discount rates are developed with input from valuation experts. Our expected lives are determined based on the contractual terms of the underlying arrangements.

        During the quarter ended March 31, 2012, we changed our estimate of payments to be made under these arrangements and recognized a gain totaling $9.9 million ($5.0 million of which is attributable to the controlling interest). Changes to our projected future payment amounts could materially affect the amount of Imputed interest expense and contingent payment arrangements we recognize in any period. For example, a 1% change in our assumed discount rate or a 1% change in our projected revenue (assuming all other factors remain constant) at Affiliates with these types of arrangements would result in an increase or decrease to our Imputed interest expense and contingent payment arrangements of $1.0 million and $7.5 million, respectively.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

        There have been no significant changes to our Quantitative and Qualitative Disclosures About Market Risk in the three months ended March 31, 2012. Please refer to Item 7A in our 2011 Annual Report on Form 10-K.

Item 4.    Controls and Procedures

        We carried out an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures during the quarter covered by this Quarterly Report on Form 10-Q. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the quarter covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures are effective in ensuring that (i) the information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934, as amended (the "Exchange Act") is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms, and (ii) such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, we recognize that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and our management necessarily was required to apply its judgment in evaluating and implementing possible controls and procedures. Our disclosure controls and procedures were designed to provide reasonable assurance of achieving their stated objectives and our principal executive officer and principal financial officers concluded that our disclosure controls and procedures are effective at the reasonable assurance level. We review on an ongoing basis and document our disclosure controls and procedures, and our internal control over financial reporting, and we may from time to time make changes in an effort to enhance their effectiveness and ensure that our systems evolve with our business.

        No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the quarter covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
