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. All dollar amounts in these notes (except information that is presented on a per share, per security, per note or per contract basis) are stated in thousands, unless otherwise indicated. 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 (as amended, the "Annual Report on Form 10-K") for the fiscal year ended December 31, 2009 includes additional information about AMG, its operations, its financial position and its accounting policies, and should be read in conjunction with this Quarterly Report on Form 10-Q.

2. Senior Bank Debt

In the fourth quarter of 2007, the Company entered into an amended and restated senior credit facility (the "Facility"). During the third quarter of 2008, the Company increased its borrowing capacity to $1,010,000, comprised of a $770,000 revolving credit facility (the "Revolver") and a $240,000 term loan (the "Term Loan"). In the first quarter of 2009, the Company repaid the outstanding balance of the Term Loan ($233,514); the capacity under the Revolver remains at $770,000. The Company pays interest on any outstanding obligations at specified rates (based either on the Eurodollar rate or the prime rate as in effect from time to time) that vary depending on the Company's credit rating. Subject to the agreement of lenders to provide additional commitments, the Company has the option to increase the Facility by up to an additional $175,000.

The Revolver, which will mature in February 2012, contains financial covenants with respect to leverage and interest coverage. The Facility also contains customary affirmative and negative covenants, including limitations on indebtedness, liens, cash dividends and fundamental corporate changes. Borrowings under the Facility are collateralized by pledges of the substantial majority of capital stock or other equity interests owned by the Company. At March 31, 2010, the Company had $170,000 of outstanding borrowings under the Revolver.

3. Senior Convertible Securities

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2008 Senior Convertible Notes

In August 2008, the Company issued $460,000 of senior convertible notes due 2038 ("2008 senior convertible notes"). The 2008 senior convertible notes bear interest at 3.95%, payable semi-annually in cash. The Company is accreting the carrying value to the principal amount at maturity using an interest rate of 7.4% (over its expected life of five years). Each security is convertible into 7.959 shares of the Company's common stock (at an initial conversion price of $125.65) upon the occurrence of certain events, as follows: (i) during any fiscal quarter, if the closing price of the Company's common stock, as measured over a specified time period during the preceding fiscal quarter, is equal to or greater than 130% of the conversion price of the notes on the last day of such preceding fiscal quarter; (ii) during a certain window of time, if the trading price per $1,000 principal amount of the notes for each day during a specified period is less than 98% of the product of the last reported sale price of the Company's common stock and the conversion rate of the notes on such day; (iii) upon the occurrence of specified corporate transactions; (iv) after the notes have been called for redemption; and (v) anytime after February 15, 2038. Upon conversion, the Company may elect to pay cash, deliver shares of its common stock, or a combination thereof. The holders of the 2008 senior convertible notes may require the Company to repurchase the notes in August of 2013, 2018, 2023, 2028 and 2033. The Company may redeem the notes for cash (subject to the holders' right to convert) at any time on or after August 15, 2013.

The 2008 senior convertible notes are considered contingent payment debt instruments under federal income tax regulations. These regulations require the Company to deduct interest in an amount greater than its reported interest expense, which will result in annual deferred tax liabilities of approximately $11,200. 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 notes.

Zero Coupon Senior Convertible Notes

In 2001, the Company issued $251,000 principal amount at maturity of zero coupon senior convertible notes due 2021 ("zero coupon convertible notes"), with each note issued at 90.50% of such principal amount and accreting at a rate of 0.50% per year. As of March 31, 2010, $50,125 principal amount at maturity remains outstanding. Each security is convertible into 17.429 shares of the Company's common stock (at a current base conversion price of $54.28) upon the occurrence of certain events, as follows: (i) during any fiscal quarter, if the closing price of a share of the Company's common stock, as measured over a specified time period during the preceding fiscal quarter, is greater than a specified conversion price (initially $62.36 and increasing incrementally at the end of each calendar quarter to $63.08 in April 2021); (ii) if the credit rating assigned by Standard & Poor's to the securities is below BB-; (iii) if the Company calls the securities for redemption and (iv) upon the occurrence of specified corporate transactions. The holders may require the Company to repurchase the securities at their accreted value in May 2011 and 2016. If the holders exercise this option in the future, the Company may elect to repurchase the securities with cash, shares of its common stock or a combination thereof. The Company has the option to redeem the securities for cash at their accreted value. Subject to changes in the price of the Company's common stock, the zero coupon convertible notes may not be convertible in certain future periods.

4. Junior Convertible Trust Preferred Securities

The carrying values of the junior convertible trust preferred securities are as follows:

	December 31, 2009				March 31, 2010

	Carrying Value		Principal amount at maturity		Carrying Value		Principal amount at maturity
2006 junior convertible trust preferred securities	$	212,466	$	300,000	$	212,734	$	300,000
2007 junior convertible trust preferred securities		294,892		430,820		295,231		430,820

Total junior convertible securities	$	507,358	$	730,820	$	507,965	$	730,820

In 2006, the Company issued $300,000 of junior subordinated convertible debentures due 2036 to a wholly-owned trust simultaneous with the issuance, by the trust, of $291,000 of convertible trust preferred securities to investors. The junior subordinated convertible debentures and convertible trust preferred securities (together, the "2006 junior convertible trust preferred securities") have substantially the same terms.

The 2006 junior convertible trust preferred securities bear interest at a rate of 5.1% per annum, payable quarterly in cash. The Company is accreting the carrying value to the principal amount at maturity using an interest rate of 7.5% (over its expected life of 30 years). Each $50 security is convertible, at any time, into 0.333 shares of the Company's common stock, which represents a conversion price of $150 per share (or a 48% premium to the then prevailing share price of $101.45). Upon conversion, holders will receive cash or shares of the Company's common stock (or a combination of cash and common stock) at the election of the Company. The 2006 junior convertible trust preferred securities may not be redeemed by the Company prior to April 15, 2011. On or after April 15, 2011, they may be redeemed if the closing price of the Company's common stock exceeds $195 per share for a specified period of time. The trust's only assets are the junior convertible subordinated debentures. To the extent that the trust has available funds, the Company is obligated to ensure that holders of the 2006 junior convertible trust preferred securities receive all payments due from the trust.

In October 2007, the Company issued an additional $500,000 of junior subordinated convertible debentures which are due 2037 to a wholly-owned trust simultaneous with the issuance, by the trust, of $500,000 of convertible trust preferred securities to investors. The junior subordinated convertible debentures and convertible trust preferred securities (together, the "2007 junior convertible trust preferred securities") have substantially the same terms.

The 2007 junior convertible trust preferred securities bear interest at 5.15% per annum, payable quarterly in cash. The Company is accreting the discounted amount to the principal amount at maturity using an interest rate of 8.0% (over its expected life of 30 years). Each $50 security is convertible, at any time, into 0.25 shares of the Company's common stock, which represents a conversion price of $200 per share (or a 53% premium to the then prevailing share price of $130.77). Upon conversion, holders will receive cash or shares of the Company's common stock (or a combination of cash and common stock) at the election of the Company. The 2007 junior convertible trust preferred securities may not be redeemed by the Company prior to October 15, 2012. On or after October 15, 2012, they may be redeemed if the closing price of the Company's common stock exceeds $260 per share for a specified period of time. The trust's only assets are the 2007 junior convertible subordinated debentures. To the extent that the trust has available funds, the Company is obligated to ensure that holders of the 2007 junior convertible trust preferred securities receive all payments due from the trust.

AFFILIATED MANAGERS GROUP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

The 2006 and 2007 junior convertible trust preferred securities are considered contingent payment debt instruments under federal income tax regulations. These regulations require the Company to deduct interest in an amount greater than its reported interest expense, which will result in annual deferred tax liabilities of approximately $9,500. 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 notes.

5. Forward Equity Sale Agreements

The Company has entered into three forward equity sale agreements with major securities firms to sell shares of its common stock (up to $200,000 under each agreement). Under the terms of these agreements, the Company can settle forward sales at any time prior to December 31, 2010 by issuing shares in exchange for cash or, at the Company's option, by settling on a net stock or cash basis. As of March 31, 2010, the Company has $349,330 of forward sales that remain unsettled at a weighted average price of $57.54.

A summary of the Company's forward equity sale agreements is as follows:

Total deferred tax liabilities			(351,618	)		(422,916	)

	Net deferred tax liability	$	(322,671	)	$	(393,263	)

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 junior convertible trust preferred securities and 2008 senior convertible notes also generate deferred taxes because the Company's tax deductions are higher than the interest expense recorded for financial statement purposes.

In March 2010, in connection with the closing of the investment in Artemis (discussed in Note 16 below), the Company recorded a deferred tax liability of approximately $67,000 for the tax effect of acquiring intangible assets that are not deductible for tax purposes in the United Kingdom.

At March 31, 2010, the Company has state net operating loss carryforwards that expire over a 15-year period beginning in 2010. The Company also has foreign tax credit carryforwards that expire over a 10-year period beginning in 2010. The valuation allowances at December 31, 2009 and March 31, 2010 were principally related to the uncertainty of the realization of the foreign tax credits and the state net operating loss carryforwards, which realization depends upon the Company's generation of sufficient taxable income prior to their expiration.

At March 31, 2010, the Company's liability for uncertain tax positions was $22,249, including interest and related charges of $4,165. The Company does not anticipate that this liability will change significantly over the next twelve months.

7. 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. Unlike all other dollar amounts in these Notes, the amounts in the numerator reconciliation are not presented in thousands.

		For the Three Months Ended March 31,

		2009		2010
Numerator:
Net Income (controlling interest)		$	6,125,000	$	17,462,000
Interest expense on convertible securities, net of taxes			36,000		24,000

Net Income (controlling interest), as adjusted		$	6,161,000	$	17,486,000

Denominator:
Average shares outstanding—basic			40,022,423		42,360,311
Effect of dilutive instruments:
	Stock options		185,904		917,575
	Forward sale		—		1,270,201
	Senior convertible securities		873,803		873,629

Average shares outstanding—diluted			41,082,130		45,421,716

As more fully discussed in Notes 3 and 4, the Company had certain 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.

The calculation of diluted earnings per share for the three months ended March 31, 2009 and 2010 excludes the potential exercise of options to purchase 4.2 million and 1.3 million common shares, respectively, because the effect would be anti-dilutive.

As discussed further in Note 18, 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.

8. 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 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 consolidated financial condition or results of operations of the Company.

AFFILIATED MANAGERS GROUP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

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

9. Investments in Partnerships

The activity in the Affiliate investments in consolidated partnerships was as follows for the three months ended March 31, 2010:


December 31, 2009		$	93,809
	Gross subscriptions		1
	Gross redemptions		(284	)
	Investment income		4,091
	Other		(313	)

March 31, 2010		$	97,304

Purchases and sales of investments (principally equity securities) were $73,160 and $73,443, respectively, for the three months ended March 31, 2010.

Management fees earned from these partnerships were $162 and $242 for the three months ended March 31, 2009 and 2010, respectively.

As of December 31, 2009 and March 31, 2010, the Affiliates' investments in partnerships that are not consolidated were $17,631 and $22,894, respectively. These assets are reported within "Other assets" in the Consolidated Balance Sheets. The income or loss related to these investments is classified within "Investment and other (income) loss" in the Consolidated Statements of Income.

10. Investments in Marketable Securities

The cost of investments in marketable securities, gross unrealized gains and losses were as follows:

	December 31, 2009			March 31, 2010

Cost of investments in marketable securities	$	50,631		$	53,342
Gross unrealized gains		6,108			27,570
Gross unrealized losses		(49	)		(98	)

11. Unsettled Fund Share Receivables and Payables

Unsettled fund share receivables and payables are created by the normal settlement periods on transactions initiated by certain clients of Affiliate funds domiciled in the United Kingdom. The gross presentation of the receivable ($154,740) and substantially offsetting payable ($159,039) reflects the legal relationship between the underlying investor and the Company.

12. 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

AFFILIATED MANAGERS GROUP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

for an asset or paid to transfer a liability in the most advantageous market, 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 reflecting the Company's own assumptions concerning unobservable inputs to the valuation model.

The following table summarizes the Company's assets (principally equity securities) and liabilities that are measured at fair value on a quarterly basis.

			Fair Value Measurements

	December 31, 2009		Fair Value Measurements

Financial Liabilities
Contingent payment obligations	$	49,105	$	—	$	—	$	49,105

During the three months ended March 31, 2010, there were no significant transfers of financial assets between Level 1 and Level 2; financial assets valued at $3,709 transferred from Level 3 to Level 2. The fair value of Level 2 assets was determined using quoted prices for similar instruments in active markets. The fair value of Level 3 assets and liabilities were determined using an income approach with assumptions made about future cash flows and discount rates.

Any change in the fair value of investments in partnerships is presented as "Investment (income) loss from investments in partnerships" in the Consolidated Statements of Income. However, the portion of this income or loss that is attributable to investors that are unrelated to the Company, if any, is

AFFILIATED MANAGERS GROUP, INC.

reported as "Net (income) loss (non-controlling interests in partnerships)." The following table presents the changes in Level 3 assets and liabilities for the three months ended March 31, 2009 and 2010:

	Financial Assets					Financial Liabilities

Amount of total gains (losses) included in other comprehensive income	$	—	$	—		$	—	$	—

The carrying amount of the Company's cash, cash equivalents and short-term investments approximates fair value because of the short-term nature of these instruments. The carrying value of notes receivable approximates fair value because interest rates and other terms are at market rates. The carrying value of notes payable approximates fair value principally because of the short-term nature of the notes. 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 zero coupon senior convertible notes, the 2008 senior convertible notes, and the 2006 and 2007 junior convertible trust preferred securities at March 31, 2010 was $69,769, $456,550 and $542,697, respectively.

13. Related Party Transactions

The Company periodically records amounts receivable and payable to Affiliate partners in connection with the transfer of Affiliate equity interests. As of December 31, 2009 and March 31, 2010, the total receivable (reported in "Other assets") was $45,253 and $41,114, respectively. The total payable as of December 31, 2009 was $109,888, of which $109,888 is included in current liabilities. The total payable as of March 31, 2010 was $18,314, of which $18,314 is included in current 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.

14. Stock Option and Incentive Plans

The following summarizes the transactions of the Company's stock option and incentive plans for the three months ended March 31, 2010:

				Weighted Average Exercise Price

Unexercised options outstanding— January 1, 2010		5,166,344		$	54.29
	Options granted	3,125			71.13
	Options exercised	(63,233	)		41.99
	Options forfeited	(2,854	)		44.57

Unexercised options outstanding— March 31, 2010		5,103,382			54.45	4.5

Exercisable at March 31, 2010		3,237,416			51.58	4.2

In addition, under the Company's Long-Term Executive Incentive and Deferred Compensation Plans, the Company granted awards during 2009. Consistent with the Company's retention and incentive objectives, including the belief that long-term equity compensation is an effective and appropriate retention tool, the awards will be earned only if specified future performance goals are obtained, and are also subject to vesting and forfeiture provisions.

The Company's Net Income (controlling interest) for the three months ended March 31, 2010 includes compensation expense of $2,241 (net of income tax benefits of $1,403 related to the Company's share-based compensation arrangements). As of March 31, 2010, the deferred compensation expense related to share-based compensation arrangements was $43,781 which is expected to be recognized over a weighted average period of approximately four years (assuming no forfeitures). As of March 31, 2010, 0.8 million options have expiration dates prior to the end of 2010.

15. 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.

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 foundations and endowments, defined benefit and defined contribution plans and Taft-Hartley plans. 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.

AFFILIATED MANAGERS GROUP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

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.

16. Goodwill and Acquired Client Relationships

The Company periodically acquires interests from, makes additional purchase payments to and transfers interests to Affiliate management partners. During the three month period ended March 31, 2010, the Company incurred $4,450 of acquisition-related costs which were recognized as selling, general and administrative expenses. The Company did not incur any such costs during the period ended March 31, 2009.

The following table presents the change in goodwill during the three months ended March 31, 2010:

	Mutual Fund		Institutional		High Net Worth		Total

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

The following table reflects the components of intangible assets of the Company's Affiliates that are consolidated as of December 31, 2009 and March 31, 2010:

		Carrying Amount		Accumulated Amortization		Carrying Amount		Accumulated Amortization

	Goodwill		1,413,217		—		1,521,222		—

For the Company's Affiliates that are consolidated, definite-lived acquired client relationships are amortized over their expected useful lives. As of March 31, 2010, these relationships were being amortized over a weighted average life of approximately 10 years. The Company estimates that its consolidated annual amortization expense will be approximately $36,000 for the next five years, assuming no additional investments in new or existing Affiliates.

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, 2010, these relationships were being amortized over approximately seven years. Amortization expense for these relationships was $8,063 for the three months ended March 31, 2010. The Company estimates that the annual amortization expense attributable to its current equity-method Affiliates will be approximately $32,000 for the next five years.

Consistent with the Company's strategic objective to make investments in boutique investment management firms, in March 2010 the Company completed a majority investment in Artemis Investment Management Ltd ("Artemis"), a firm which specializes in active investment management for retail and institutional investors in the U.K. as well as Europe and the Middle East.

The Company's purchase price allocation is provisional because the Company has not yet completed the valuation of the acquired client relationships, deferred income taxes, contingent payment obligations or the non-controlling interest. As a result, provisional amounts may be revised in future periods. The excess of the enterprise value over the net assets acquired was recorded as goodwill, of which 94% and 6% was attributed to the Company's Mutual Fund and Institutional segments,

AFFILIATED MANAGERS GROUP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

respectively. The goodwill and acquired client relationships are deductible for U.S. tax purposes over a 15 year life. The provisional allocation of the purchase price is as follows:

Consideration

Purchase price	$	157,838
Contingent payment obligation		24,973

Purchase Price	$	182,811

Acquired client relationships, net	$	238,666
Tangible assets, net		42,261
Deferred income taxes		(66,826	)
Non-controlling interests		(130,833	)
Goodwill		99,543

	$	182,811

As part of this investment, the Company and the non-controlling interest are contingently liable to make payments of between zero and £105,000 in November of 2012 upon the achievement of specified revenue targets. The Company measured the provisional fair value of the contingent payment obligation using a financial model that included assumptions of expected market performance and net client cash flows. Based on these assumptions, the Company projects a contingent payment of $80,332 in 2012. As of March 31, 2010, the present value of this payment was $49,105 ($24,061 is attributable to the non-controlling interest). These amounts are reported in "Other long-term liabilities."

Unaudited pro forma financial results are set forth below, giving consideration to the Artemis investment, as if such transactions occurred as of the beginning of 2009, assuming the revenue sharing arrangement had been in effect for the entire period and after making certain other pro forma adjustments.

	For the Three Months Ended March 31,

	2009		2010
Revenue	$	222,487	$	292,380
Net Income (controlling interest)		9,351		19,753
Earnings per share—basic		0.23		0.47
Earnings per share—diluted		0.23		0.43

Artemis' contribution to the Company's revenue and earnings in the quarter ended March 31, 2010 was not material.

17. Recent Accounting Developments

During the first quarter of 2010, the Company adopted a new standard that requires an enterprise to perform a qualitative analysis to determine whether its variable interests give it a controlling financial interest in a variable interest entity ("VIE"). Under the standard, an enterprise has a controlling financial interest when it has (a) the power to direct the activities of a VIE that most significantly impact the entity's economic performance and (b) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the VIE. An enterprise that holds a controlling financial interest is deemed to be the primary beneficiary and is

AFFILIATED MANAGERS GROUP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

required to consolidate the VIE. This new standard has been deferred for certain entities that utilize the specialized accounting guidance for investment companies or that have the attributes of investment companies. The adoption of the portions of this new standard that were not deferred did not have a material impact on the Company's Consolidated Financial Statements.

During the first quarter of 2010, the Company adopted a new standard that eliminated the concept of a qualifying special-purpose entity ("QSPE"), changed the requirements for derecognizing financial assets, and required additional disclosures to enhance information reported to users of financial statements by providing greater transparency about transfers of financial assets, including an entity's continuing involvement in and exposure to the risks related to transferred financial assets. The standard also clarified the requirements for isolation and limitations on portions of financial assets that are eligible for sale accounting. The adoption of this new standard did not have a material impact on the Company's Consolidated Financial Statements.

18. Affiliate Equity

Many of the Company's operating agreements provide Affiliate managers a conditional right to require the Company to purchase their retained equity interests at certain intervals. Certain agreements also provide the Company a conditional right to require Affiliate managers to sell their retained equity interests to the Company upon their death, permanent incapacity or termination of employment and provide Affiliate managers a conditional right to require the Company to purchase such retained equity interests upon the occurrence of specified events. 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 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 Company's cumulative redemption obligation for these interests has been presented as "Redeemable non-controlling interests" on the Company's Consolidated Balance Sheets. Changes in the value of the Company's cumulative redemption obligation 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, 2010	$	368,999

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.

Overview

We are a global asset management company with equity investments in a diverse group of boutique investment management firms (our "Affiliates"). We pursue a growth strategy designed to generate shareholder value through the internal growth of our existing business, additional investments in investment management firms and strategic transactions and relationships structured to enhance our Affiliates' businesses and growth prospects.

As of March 31, 2010, we manage approximately $232.1 billion in assets through our Affiliates (approximately $260.0 billion pro forma for the transactions discussed below in Pending Investments) in more than 300 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 exposure to the risks created by changing market environments. The following summarizes our operations in our three principal distribution channels.

•: Our Affiliates provide advisory or sub-advisory services to approximately 200 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, our Affiliates offer approximately 200 investment products across approximately 50 different investment styles, including small, small/mid, mid and large capitalization value, growth equity and emerging markets. In addition, our Affiliates offer quantitative, alternative, credit arbitrage and fixed income products. Through this distribution channel, our Affiliates manage assets for foundations and endowments, defined benefit and defined contribution plans for corporations and municipalities, and Taft-Hartley plans, 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, generally brokerage firms or other sponsors. Our Affiliates provide investment management services through approximately 100 managed account and wrap programs.

Pending Investments

On April 15, 2010, we completed our investment in Aston Asset Management LLC ("Aston") through the acquisition of Highbury Financial Inc., Aston's parent company. Based in Chicago, Aston offers sub-advised investment products to the mutual fund and managed accounts markets. Aston is the principal advisor to the Aston Funds, a fund family of 24 sub-advised, no-load mutual funds with total net assets of approximately $7.6 billion as of March 31, 2010.

In February 2010, we announced an agreement to purchase Pantheon Ventures Inc., Pantheon Holdings Limited and Pantheon Capital (Asia) Limited (collectively, "Pantheon"). Pantheon manages regional funds-of-funds in Europe, the United States and Asia, as well as global secondary funds-of-funds, global infrastructure fund-of-funds and customized separate account programs, with total assets under management of approximately $21 billion as of March 31, 2010. Subject to customary closing conditions, regulatory approvals and compliance with other terms of the purchase agreement, we anticipate the investment in Pantheon will close in the second quarter of 2010.

Our Structure and Relationship with Affiliates

We operate our business through our Affiliates in our three principal distribution channels, maintaining each Affiliate's distinct entrepreneurial culture and independence through our investment structure. 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.

Although the specific structure of each investment is highly tailored to meet the needs of a particular Affiliate, in all cases, AMG establishes 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 the 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. However, should actual operating expenses exceed the Operating Allocation, 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.

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.

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 AMG and our Affiliate partners 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.

Through our affiliated investment management firms, we derive most of our revenue from the provision of investment management services. Investment management fees ("asset-based fees") are usually determined as a percentage fee charged on periodic values of a client's assets under

management; most asset-based advisory fees are billed by our Affiliates quarterly. Certain clients are billed for all or a portion of their accounts based upon assets under management valued at the beginning of a billing period ("in advance"). Other clients are billed for all or a portion of their accounts based upon assets under management valued at the end of the billing period ("in arrears"). Most client accounts in the High Net Worth distribution channel are billed in advance, and most client accounts in the Institutional distribution channel are billed in arrears. Clients in the Mutual Fund distribution channel are billed based upon average daily assets under management. Advisory fees billed in advance will not reflect subsequent changes in the market value of assets under management for that period but may reflect changes due to client withdrawals. Conversely, advisory fees billed in arrears will reflect changes in the market value of assets under management for that period.

In addition, over 75 Affiliate alternative investment and equity products, representing approximately $35 billion of assets under management (as of March 31, 2010), also bill on the basis of absolute or relative investment performance ("performance fees"). These products, which are primarily in the Institutional distribution channel, are often structured to have returns that are not directly correlated to changes in broader equity indices and, if earned, the performance fee component is typically billed less frequently than an asset-based fee. Although performance fees inherently depend on investment results and will vary from period to period, we anticipate performance fees to be a recurring component of our revenue. We also anticipate that, within any calendar year, the majority of any performance fees will typically be realized in the fourth quarter.

For certain of our Affiliates, generally where we own a non-controlling interest, 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 (controlling interest) and EBITDA. As a consequence, increases or decreases in these firms' assets under management (which totaled $57.4 billion as of March 31, 2010) will not affect reported revenue in the same manner as changes in assets under management at our other Affiliates.

Our Net Income attributable to controlling interest reflects the revenue of our consolidated Affiliates and our share of income from Affiliates which we account for under the equity method, reduced by:

•: our expenses, including the operating expenses of our consolidated Affiliates; and
•: the profits allocated to managers of our consolidated Affiliates (i.e., income attributable to non-controlling interests).

As discussed above, for consolidated Affiliates with revenue sharing arrangements, the operating expenses of the Affiliate as well as its managers' non-controlling interest generally increase (or decrease) as the Affiliate's revenue increases (or decreases) because of the direct relationship established in many of our agreements between the Affiliate's revenue and its Operating Allocation and Owners' Allocation. At our consolidated profit-based Affiliates, expenses may or may not correspond to increases or decreases in the Affiliates' revenues.

Our level of profitability will depend on a variety of factors, including:

•: those affecting the global financial markets generally and the equity markets particularly, which could potentially result in considerable increases or decreases in the assets under management at our Affiliates;
•: the level of Affiliate revenue, which is dependent on the ability of our existing and future Affiliates to maintain or increase assets under management by maintaining their existing

investment advisory relationships and fee structures, marketing their services successfully to new clients and obtaining favorable investment results;

•: our receipt of Owners' Allocation from Affiliates with revenue sharing arrangements, which depends on the ability of our existing and future Affiliates to maintain certain levels of operating profit margins;
•: the increases or decreases in the revenue and expenses of Affiliates that operate on a profit-based model;
•: the availability and cost of the capital with which we finance our existing and new investments;
•: our success in making new investments and the terms upon which such transactions are completed;
•: the level of intangible assets and the associated amortization expense resulting from our investments;
•: the level of our expenses, including compensation for our employees; and
•: the level of taxation to which we are subject.

Results of Operations

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).

(1): Represents certain Affiliate products that we elected to close; these transactions are not material to our ongoing financial results.

As shown in the assets under management table above, client cash inflows totaled $11.3 billion while client cash outflows totaled $12.8 billion for the three months ended March 31, 2010. The net flows for the three months ended March 31, 2010 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 takes into consideration the billing patterns of

particular client accounts. For example, assets under management for an account that bills in advance is included in the table using beginning of period assets under management while an account that bills in arrears uses end of period assets under management. We believe that this analysis more closely correlates to the billing cycle of each distribution channel and, as such, provides a more meaningful relationship to revenue.

(1): As described above, our average assets under management considers balances used to bill revenue during the reporting period. These amounts also include assets managed by firms whose financial results are not consolidated ($41.1 billion and $56.6 billion for the three months ended March 31, 2009 and 2010, respectively). Assets under management attributable to any investments in new Affiliates are included on a weighted average basis for the period from the closing date of the respective investment.
(2): EBITDA represents earnings before interest expense, income taxes, depreciation and amortization. Our use of EBITDA, including reconciliation to cash flow from operations, is described in greater detail in "Liquidity and Capital Resources—Supplemental Liquidity Measure." For purposes of our distribution channel operating results, expenses not incurred directly by Affiliates have been allocated based on the proportion of aggregate cash flow distributions reported by each Affiliate in the particular distribution channel.

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. As described in the "Overview" section above, 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 increased $72.5 million (or 41%) in the three months ended March 31, 2010, as compared to the three months ended March 31, 2009, primarily from a 33% increase in average assets under management. This increase in average assets under management resulted principally from investment performance, partially offset by negative net client cash flows. Performance fees were not a significant component of revenue in either the three months ended March 31, 2010 or the three months ended March 31, 2009 (approximately 1% of revenue for both time periods).

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

Mutual Fund Distribution Channel

Our revenue in the Mutual Fund distribution channel increased $29.6 million (or 43%) in the three months ended March 31, 2010 as compared to the three months ended March 31, 2009, while average assets under management increased 47%. The increase in average assets under management resulted principally from investment performance and our 2009 and 2010 investments in new Affiliates.

Institutional Distribution Channel

Our revenue in the Institutional distribution channel increased $39.5 million (or 48%) in the three months ended March 31, 2010 as compared to the three months ended March 31, 2009, while average assets under management increased 33%. The increase in average assets under management resulted principally from investment performance, partially offset by negative net client cash flows. The increase in revenue was proportionately greater than the increase in average assets under management as a result of an increase in assets under management at Affiliates that realize comparatively higher fee rates.

High Net Worth Distribution Channel

Our revenue in the High Net Worth distribution channel increased $3.4 million (or 12%) in the three months ended March 31, 2010 as compared to the three months ended March 31, 2009, while average assets under management increased 19%. This increase in average assets under management resulted principally from investment performance.

Operating Expenses

The following table summarizes our consolidated operating expenses:

	For the Three Months Ended March 31,

(dollars in millions)	2009		2010		% Change
Compensation and related expenses	$	84.2	$	119.2		42	%
Selling, general and administrative		32.5		46.1		42	%
Amortization of intangible assets		8.1		8.9		10	%
Depreciation and other amortization		3.3		3.0		(9	%)
Other operating expenses		5.7		6.1		7	%

Total operating expenses	$	133.8	$	183.3		37	%

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 impacted by increases or decreases in each Affiliate's revenue and the corresponding increases or decreases in each Affiliate's respective Operating Allocation. During the three months ended March 31, 2010, approximately $55.9 million (or 47%) of our consolidated compensation expense was attributable to our Affiliate management partners. The percentage of revenue allocated to operating expenses varies from one Affiliate to another and may also 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 42% in the three months ended March 31, 2010, as compared to the three months ended March 31, 2009, primarily as a result of the relationship between revenue and operating expenses at Affiliates, which experienced increases in revenue, and accordingly, reported higher compensation expenses. This increase was also attributable to an increase in aggregate Affiliate expenses of $5.1 million from new Affiliate investments as well as an increase in holding company share-based compensation of $2.5 million in the three months ended March 31, 2010 as compared to the three months ended March 31, 2009. These increases were partially offset by a decrease in aggregate Affiliate expenses from the transfer of our interests in certain Affiliates of $2.0 million in the three months ended March 31, 2010, as compared to the three months ended March 31, 2009.

Selling, general and administrative expenses increased 42% in the three months ended March 31, 2010, as compared to the three months ended March 31, 2009. This increase resulted principally from an increase in aggregate Affiliate expenses of $8.6 million from new Affiliate investments and $4.5 million of acquisition-related professional fees in the three months ended March 31, 2010 as compared to the three months ended March 31, 2009.

Amortization of intangible assets increased 10% in the three months ended March 31, 2010 as compared to the three months ended March 31, 2009. This increase was principally attributable to an increase in definite-lived intangible assets resulting from new Affiliate investments.

Depreciation and other amortization decreased 9% in the three months ended March 31, 2010 as compared to the three months ended March 31, 2009, principally attributable to a decrease in spending on depreciable assets in recent periods, partially offset by an increase of $0.1 million in aggregate Affiliate expenses from new Affiliate investments.

Other operating expenses increased 7% in the three months ended March 31, 2010 as compared to the three months ended March 31, 2009, principally attributable an increase in aggregate Affiliate expenses from new Affiliate investments.

Other Income Statement Data

The following table summarizes other income statement data:

	For the Three Months Ended March 31,

(dollars in millions)	2009			2010		% Change
Income from equity method investments	$	6.4		$	9.1		42	%
Investment and other income (loss)		(0.2	)		2.8		n.m.	⁽¹⁾
Investment income (loss) from Affiliate investments in partnerships		(3.8	)		4.1		n.m.	⁽¹⁾
Interest expense		19.9			19.9		0	%
Income tax expense		3.9			11.2		187	%

(1): The percentage change is not meaningful.

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 42% in the three months ended March 31, 2010 as compared to the three months ended March 31, 2009, principally as a result of increases in assets under management at Affiliates that we account for under the equity method of accounting.

Investment and other income increased significantly in the three months ended March 31, 2010 as compared to the three months ended March 31, 2009, principally as a result of an increase in Affiliate investment earnings.

Investment income (loss) from Affiliate investments in partnerships relates to the consolidation of certain investment partnerships in which our Affiliates are the general partner. For the three months ended March 31, 2009 and 2010, the income (loss) from Affiliate investments in partnerships was $(3.8) million and $4.1 million, respectively. This income (loss) was principally attributable to investors who are unrelated to us.

Interest expense was generally flat in the three months ended March 31, 2010, as compared to the three months ended March 31, 2009, as a decrease in the cost of our senior bank debt of $0.3 million (which resulted from a decline in borrowings) was offset by an increase in the interest accretion on our senior convertible securities.

Income taxes increased 187% in the three months ended March 31, 2010, as compared to the three months ended March 31, 2009, as a result of the increase in Net Income (controlling interest).

Net Income

The following table summarizes Net Income:

		For the Three Months Ended March 31,

(dollars in millions)		2009			2010		% Change
Net income (non-controlling interests)		$	20.9		$	31.3		50	%
	Net income (loss) (non-controlling interests in partnerships)		(3.8	)		4.0		n.m.	⁽¹⁾
Net Income (controlling interest)			6.1			17.5		187	%

(1): The percentage change is not meaningful.

Net income attributable to non-controlling interests increased 50% in the three months ended March 31, 2010, as compared to the three months ended March 31, 2009, principally as a result of the previously discussed changes in revenue.

Net income (loss) (non-controlling interest in partnerships) relates to the consolidation of certain investment partnerships in which our Affiliates are the general partner. For the three months ended March 31, 2009 and 2010, the net income (loss) from Affiliate investment partnerships attributable to the non-controlling interests was $(3.8) million and $4.0 million, respectively.

Net Income (controlling interest) increased 187% in the three months ended March 31, 2010, as compared to the three months ended March 31, 2009 as a result of increases in revenue and income from equity method investments. These increases were partially offset by increases in reported operating and income tax expenses as well as Net income attributable to non-controlling interest, as described above.

Supplemental Performance Measures

As supplemental information, we provide non-GAAP performance measures that we refer to as Cash Net Income and Cash earnings per share. We consider Cash Net Income as 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. Cash Net Income and Cash 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; Cash Net Income and Cash earnings per share are not liquidity measures and should not be used in place of any liquidity measure calculated under GAAP. These measures facilitate comparisons to other asset management firms that have not engaged in significant acquisitions or issued convertible debt.

Under our Cash Net Income definition, we add to Net Income (controlling interest) amortization (including equity method amortization), deferred taxes related to intangible assets, Affiliate depreciation and Affiliate equity expense, and exclude the non-cash effect of APB 14-1 (principally imputed interest on convertible securities) and non-cash expenses related to contingent payment arrangements. 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. Since our acquired assets do not generally depreciate or require replacement by us, and since they generate deferred tax expenses that are unlikely to reverse, we add back these non-cash expenses to Net Income to measure operating performance. 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. We add back the portion of consolidated depreciation expense incurred by our Affiliates because under our Affiliates' operating agreements we are generally not required to replenish these depreciating assets.

Cash earnings per share represents Cash 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.

In connection with recent investments in Affiliates, in the first quarter of 2010 we modified our Cash Net Income definition to exclude non-cash imputed interest and revaluation adjustments related to contingent payment arrangements from Net Income (controlling interest). The modification of the Cash Net Income definition did not have an impact on the periods reported herein.

The following table provides a reconciliation of Net Income (controlling interest) to Cash Net Income and the calculation of Cash earnings per share:

		For the Three Months Ended March 31,

(in millions, except shares and per share data)		2009			2010
Net Income (controlling interest)		$	6.1		$	17.5
	Intangible amortization⁽¹⁾		16.0			16.7
	Intangible-related deferred taxes		9.6			10.7
	Imputed interest and contingent payment adjustments		2.1			2.3
	Affiliate equity expense		2.0			1.7
	Affiliate depreciation		1.9			1.9

Cash Net Income		$	37.7		$	50.8

Average shares outstanding—diluted			41,082,130			45,421,716

	Assumed issuance of junior convertible securities shares		—			—
	Dilutive impact of senior convertible securities shares		—			209,713
	Dilutive impact of junior convertible securities shares		—			—

Average shares outstanding—adjusted diluted			40,208,327			44,757,800

Cash earnings per share		$	0.94		$	1.14

(1): As discussed in Note 1 to the Consolidated Financial Statements, 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 expenses) in our income statement. Our share of these investments' amortization is reported in "Income (loss) from equity method investments."

Cash Net Income increased 35% in the three months ended March 31, 2010 as compared to the three months ended March 31, 2009, primarily as a result of the previously-described factors that caused an increase in Net Income as well as increases in amortization and intangible-related deferred tax expenses.

Liquidity and Capital Resources

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

(in millions)	December 31, 2009		March 31, 2010

Balance Sheet Data
Cash and cash equivalents	$	259.5	$	203.8
Senior bank debt		—		170.0
2008 senior convertible notes		409.6		412.7
Zero coupon convertible notes		47.4		47.4
Junior convertible trust preferred securities		507.4		508.0

	For the Three Months Ended March 31,

	2009			2010
Cash Flow Data
Operating cash flow	$	15.7		$	68.0
Investing cash flow		(3.7	)		(131.9	)
Financing cash flow		(170.7	)		7.5
EBITDA⁽¹⁾		49.2			68.2

(1): The definition of EBITDA is presented in Note 2 on page 27 and 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 (including prospective proceeds from the settlement of our forward equity sale agreements). At March 31, 2010, our internal leverage ratio was 1.2:1.

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 3.5. 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 the purposes of calculating these ratios, share-based compensation expense is added back to EBITDA. As of March 31, 2010, our actual bank leverage and bank interest coverage ratios were 2.4 and 5.0, respectively, and we were in full compliance with all terms of our credit facility. Following the closing of our investment in Aston, we have $600 million of remaining capacity under our $770 million credit facility, of which we could borrow a total of $575 million without violating credit facility covenants.

Our investment in Aston was closed in April and was financed through the issuance of 1.7 million shares of our common stock. We plan to finance our investment in Pantheon with borrowings under our credit facility and $100 million of proceeds from the partial settlement of forward equity sales. Following the closing of our pending new investments, we anticipate our bank leverage ratio will increase to approximately 3.0.

We are rated BBB- by Standard & Poor's. A downgrade of our credit rating, either as a result of industry or company-specific considerations, would not have a material financial effect on any of our agreements or securities (or otherwise trigger a default).

Supplemental Liquidity Measure

As supplemental information in this Quarterly Report on Form 10-Q, 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 operations. 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)		2009			2010
Cash flow from operations		$	15.7		$	68.0
	Interest expense, net of non-cash items⁽¹⁾		14.7			14.2
	Current tax provision		(8.0	)		2.5
	Income from equity method investments, net of distributions⁽²⁾		(4.6	)		(6.0	)
	Changes in assets and liabilities and other adjustments⁽³⁾		31.4			(10.5	)

EBITDA		$	49.2		$	68.2

(1): Non-cash items represent amortization of issuance costs and interest accretion ($5.2 million and $5.6 million for the three months ended March 31, 2009 and 2010, respectively).
(2): Distributions from equity method investments were $18.9 million and $23.2 million for the three months ended March 31, 2009 and 2010, respectively.
(3): Other adjustments include stock option expenses, tax benefits from stock options, Net income attributable to non-controlling interests and other adjustments to reconcile Net Income (controlling interest) to net cash flow from operating activities.

In the three months ended March 31, 2010, we met our cash requirements primarily through cash generated by operating activities. Our principal uses of cash in the three months ended March 31, 2010 were to make distributions to Affiliate managers and repay our senior bank debt. We expect that our principal uses of cash for the foreseeable future will be for investments in new and existing Affiliates, distributions to Affiliate managers, payment of interest on outstanding debt, the repurchase of debt securities, and the repurchase of shares of our common stock 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, 2010:

(in millions)	Amount		Maturity Date	Form of Repayment

Senior Bank Debt	$	170.0	2012	(1)
Zero Coupon Senior Convertible Notes		50.1	2021	(2)
2008 Senior Convertibles Notes		460.0	2038	(3)
Junior Convertible Trust Preferred Securities		730.8	2036/2037	(4)

(1): Settled in cash.

(2): Settled in cash or common stock (or a combination thereof) at our election if holders exercise their May 2011 or 2016 put rights, and in common stock if the holders exercise their conversion rights.
(3): Settled in cash if holders exercise their August 2013, 2018, 2023, 2028 or 2033 put rights, and in cash or common stock (or a combination thereof) at our election if the holders exercise their conversion rights.
(4): Settled in cash or common stock (or a combination thereof) at our election if the holders exercise their conversion rights.

Senior Bank Debt

We have a $770 million revolving credit facility (the "Revolver") under which we pay interest at specified rates (based either on the LIBOR rate or the prime rate as in effect from time to time) that vary depending on our credit rating. Subject to the agreement of lenders to provide additional commitments, we have the option to increase the Revolver by up to $175 million. The Revolver contains financial covenants with respect to leverage and interest coverage and customary affirmative and negative covenants, including limitations on indebtedness, liens, cash dividends and fundamental corporate changes. Borrowings under the Revolver are collateralized by pledges of the substantial majority of our capital stock or other equity interests owned by us. As of March 31, 2010, we had $170 million outstanding under the Revolver.

Senior Convertible Securities

We have two senior convertible securities outstanding at March 31, 2010. The principal terms of these notes are summarized below.

	Zero Coupon Convertible Notes			2008 Convertible Notes

Issue Date		May 2001			August 2008
Maturity Date		May 2021			August 2038
Par Value	$	47.4		$	460.0

Current Conversion Price	$	54.28		$	125.65
Stated Coupon		—			3.95	%
Tax Deduction Rate		0.50	%		9.38%	⁽²⁾

(1): The carrying value is accreted to the principal amount at maturity using an interest rate of 7.4%.
(2): The 2008 convertible notes are considered contingent payment debt instruments under tax regulations that require us to deduct interest in an amount greater than our cash coupon rate.

The zero coupon convertible notes are convertible into a defined number of shares of our common stock upon the occurrence of certain events. The holders may put these securities to us in May 2011 and 2016. If the holders exercise this option, we can settle the repurchases with cash or shares of our common stock, or a combination thereof. We have the option to call securities at any time for cash at their accreted value.

The 2008 convertible notes are convertible into a defined number of shares of our common stock upon the occurrence of certain events. Upon conversion, we may elect to pay or deliver cash, shares of common stock, or some combination thereof. The holders of the 2008 convertible notes may put these securities to us in August of 2013, 2018, 2023, 2028 and 2033. We may call the notes for cash at any time on or after August 15, 2013.

Junior Convertible Trust Preferred Securities

We have two junior convertible trust preferred securities outstanding at March 31, 2010, 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.

	2006 Junior Convertible Trust Preferred Securities			2007 Junior Convertible Trust Preferred Securities

Issue Date		April 2006			October 2007
Maturity Date		April 2036			October 2037
Par Value	$	300.0		$	430.8

Stated Coupon		5.10	%		5.15	%
Tax Deduction Rate		7.50%	⁽³⁾		8.00%	⁽³⁾

(1): The carrying value is accreted to the principal amount at maturity using an interest rate of 7.5% (over its expected life of 30 years).
(2): The carrying value is accreted to the principal amount at maturity using an interest rate of 8.0% (over its expected life of 30 years).
(3): The 2006 and 2007 junior convertible trust preferred securities are considered contingent payment debt instruments under the federal income tax regulations. We are required to deduct interest in an amount greater than our cash coupon rate.

Both the 2006 and 2007 junior convertible trust preferred securities are convertible, at any time, into a defined number of shares. Upon conversion, holders will receive cash or shares of our common stock, or a combination thereof. We can call the 2006 junior convertible trust preferred securities on or after April 2011 if the closing price of our common stock exceeds $195 per share for a specified period of time.

We can call the 2007 junior convertible trust preferred securities on or after October 2012 if the closing price of our common stock exceeds $260 per share for a specified period of time.

Holders of the 2006 and 2007 junior trust preferred securities have no rights to put these securities to us.

Forward Equity Sale Agreement

We have entered into three forward equity sale agreements with major securities firms to sell shares of our common stock (up to $200 million under each agreement). Under the terms of these agreements, we can settle forward sales at any time prior to December 31, 2010 by issuing shares in exchange for cash. Alternatively, we may choose to settle forward sales on a net stock or cash basis.

Through March 31, 2010, we have completed $496.5 million of forward sales. In March 2009, we settled $147.2 million of forward equity sales by issuing 1.8 million shares of our common stock. The weighted average exercise price of our forward equity sales that remain unsettled is $57.54.

A summary of our forward equity sale agreements is as follows:

Agreement	Amount Sold		Amount Settled		Amount Unsettled⁽¹⁾

May 2008	$	200.0	$	147.2	$	52.8
May 2009		200.0		—		200.0
July 2009		96.5		—		96.5

	$	496.5	$	147.2	$	349.3

(1): Before transaction costs.

Affiliate Equity

Many of our operating agreements provide Affiliate managers a conditional right to require us to purchase their retained equity interests at certain intervals. Certain agreements also provide us a conditional right to require Affiliate managers to sell their retained equity interests to us upon their death, permanent incapacity or termination of employment and provide Affiliate managers a conditional right to require us to purchase such retained equity interests upon the occurrence of specified events. 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.

We may pay for Affiliate equity purchases in cash, shares of our common stock or other forms of consideration and can consent to the transfer of these interests to other individuals or entities. Our cumulative redemption obligation 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 $100 million of Affiliate equity during the next twelve months, 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 increase in cash flows from operations for the three months ended March 31, 2010 as compared to the three months ended March 31, 2009, resulted principally from increased Net Income of $29.5 million and a decrease in settlements of liabilities of $51.0 million, partially offset by a decrease in collections of investment advisory fees receivable of $30.3 million.

We consolidated $93.8 million and $97.3 million of client assets held in partnerships controlled by our Affiliates as of December 31, 2009 and March 31, 2010, respectively. Sales of $1.0 million and $0.3 million increased operating cash flow in the three months ended March 31, 2009 and March 31, 2010, respectively.

Investing Cash Flow

The net cash flow used in investing activities increased $128.2 million for the three months ended March 31, 2010 as compared to the three months ended March 31, 2009. This was primarily the result of an increase of $127.7 million in investments in Affiliates in the current period.

As discussed above in Pending Investments, during the second quarter we completed our investment in Aston and plan to complete our investment in Pantheon.

Financing Cash Flow

Net cash flows from financing activities increased $178.2 million for the three months ended March 31, 2010, as compared to the three months ended March 31, 2009. This was primarily as a result of an increase in net senior bank debt activity of $403.5 million, partially offset by $144.3 million received from settlements under our forward equity sale agreement in the first quarter of 2009 (as discussed above) and an increase in repurchases of Affiliate equity of $86.3 million.

Our investment in Artemis was financed through borrowings under our credit facility, and our investment in Aston was financed through the issuance of approximately 1.7 million shares of our common stock. We plan to finance our investment in Pantheon with borrowings under our credit facility and $100 million of proceeds from the partial settlement of forward equity sales.

Under past acquisition agreements, we are contingently liable, upon achievement of specified financial targets, to make payments of up to $378 million through 2012. In the remainder of 2010, we do not expect to make any significant payments to settle portions of these contingent obligations.

Proceeds available under our Facility and forward equity sale agreements are sufficient to support our cash flow needs for the foreseeable future.

Contractual Obligations

The following table summarizes our contractual obligations as of March 31, 2010:

			Payments Due

Contractual Obligations	Total		Remainder of 2010		2011-2012		2013-2014		Thereafter

Contingent Obligations
Contingent payment obligations⁽⁴⁾	$	80.3	$	—	$	80.3	$	—	$	—

(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 million in 2013, and holders of our zero coupon convertible notes may put their interests to us for $47 million in 2011.
(2): As more fully discussed on page 33, consistent with industry practice, we do not consider our junior convertible trust preferred securities as debt for the purpose of determining our leverage ratio.

(3): Other liabilities reflect amounts payable to Affiliate managers related to our purchase of additional Affiliate equity interests. This table does not include liabilities for uncertain tax positions ($22.2 million as of March 31, 2010) as we cannot predict when such liabilities will be paid.
(4): The amount of contingent payments related to business acquisitions disclosed in the table represents our expected settlement amounts. While the table above reflects our current estimates, the maximum settlement amount is $166 million for the remainder of 2010 and $212 million in periods after 2010.

Recent Accounting Developments

During the first quarter of 2010, we adopted a new standard that requires an enterprise to perform a qualitative analysis to determine whether its variable interests give it a controlling financial interest in a variable interest entity ("VIE"). Under the standard, an enterprise has a controlling financial interest when it has (a) the power to direct the activities of a VIE that most significantly impact the entity's economic performance and (b) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the VIE. An enterprise that holds a controlling financial interest is deemed to be the primary beneficiary and is required to consolidate the VIE. This new standard has been deferred for certain entities that utilize the specialized accounting guidance for investment companies or that have the attributes of investment companies. The adoption of the portions of this new standard that were not deferred did not have a material impact on our Consolidated Financial Statements.

During the first quarter of 2010, we adopted a new standard that eliminated the concept of a qualifying special-purpose entity ("QSPE"), changed the requirements for derecognizing financial assets, and required additional disclosures to enhance information reported to users of financial statements by providing greater transparency about transfers of financial assets, including an entity's continuing involvement in and exposure to the risks related to transferred financial assets. The standard also clarified the requirements for isolation and limitations on portions of financial assets that are eligible for sale accounting. The adoption of this new standard did not have a material impact on our Consolidated Financial Statements.

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, 2010. Please refer to Item 7A in our 2009 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 officers 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.
