AFFILIATED MANAGERS GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)
1.Basis of Presentation and Use of Estimates
The Consolidated Financial Statements of Affiliated Managers Group, Inc. (“AMG” or the “Company”) have been
prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) for interim financial information
and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X.  Accordingly, they do not include all of the
information and footnotes required by GAAP for full year financial statements.  In the opinion of management, all normal and
recurring adjustments considered necessary for a fair statement of the Company’s interim financial position and results of
operations have been included and all intercompany balances and transactions have been eliminated.  Operating results for
interim periods are not necessarily indicative of the results that may be expected for any other period or for the full year.  The
Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 includes additional information about its
operations, financial position, and accounting policies, and should be read in conjunction with this Quarterly Report on
Form 10-Q.
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions
that affect the reported amounts and disclosures in the financial statements.  Actual results could differ from those estimates.
All amounts in these notes, except per share data in the text and tables herein, are stated in millions unless otherwise
indicated.
2.Accounting Standards and Policies
Recently Adopted Accounting Standards
Effective January 1, 2024, the Company adopted Accounting Standard Update (“ASU”) 2022-03, Fair Value Measurement
(Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions.  The adoption of this
standard did not have a material impact on the Company’s Consolidated Financial Statements.
Recent Accounting Developments
In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-07, Segment Reporting (Topic
280): Improvements to Reportable Segment Disclosures, which requires disclosure of incremental segment information on an
annual and interim basis for all public entities to enable investors to develop more decision-useful financial analyses.  The
standard is effective for annual periods beginning after December 15, 2023 and for interim periods beginning after December
15, 2024.  The Company currently does not expect the adoption to have a material impact on its Consolidated Financial
Statements.
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures,
which requires greater disaggregation of income tax disclosures related to the income tax rate reconciliation and income taxes
paid.  The standard is effective for annual periods beginning after December 15, 2024.  The Company currently does not expect
the adoption to have a material impact on its Consolidated Financial Statements.
In March 2024, the FASB issued ASU 2024-01, Compensation—Stock Compensation (Topic 718): Scope Application of
Profits Interest and Similar Awards, which clarifies how an entity should apply the scope guidance to determine whether profits
interest and similar awards should be accounted for in accordance with Topic 718.  The standard is effective for interim and
annual periods beginning after December 15, 2024 for the Company, and is effective for interim and annual periods beginning
after December 15, 2025 for the Company’s Affiliates.  The Company currently does not expect the adoption to have a material
impact on its Consolidated Financial Statements.

held as of September 30, 2024 of $0.8 million and $1.4 million, respectively.
4.Other Investments
Other investments consists primarily of investments in funds advised by the Company’s Affiliates that are carried at net
asset value (“NAV”) as a practical expedient and other investments without readily determinable fair values.  Any gain or loss
related to these investments is recorded in Investment and other income in the Consolidated Statements of Income. 
Investments Measured at NAV as a Practical Expedient
The Company’s Affiliates sponsor funds in which the Company and its Affiliates may make general partner and seed
capital investments.  These funds generally operate in partnership form and apply the specialized fair value accounting for
investment companies.  The Company accounts for its interests in these funds using the equity method of accounting and is
required to retain the specialized fair value accounting of the investment companies.  Because the funds’ investments do not
have readily determinable fair values, the Company uses the NAV of these investments as a practical expedient for their fair
values.  The following table summarizes the fair values of these investments and any related unfunded commitments:

___________________________
(1)The Company accounts for the majority of its interests in private equity funds one quarter in arrears (adjusted for current
period calls and distributions).  These funds primarily invest in a broad range of third-party funds and direct investments. 
Distributions will be received as the underlying assets are liquidated over the life of the funds, which is generally up to 15
years.
(2)These are multi-disciplinary funds that invest across various asset classes and strategies, including equity and credit. 
Investments are generally redeemable on a daily, monthly, or quarterly basis.
(3)Fair value attributable to the controlling interest was $324.9 million and $363.4 million as of December 31, 2023 and
September 30, 2024, respectively.
Investments Without Readily Determinable Fair Values
The Company made an investment in a private corporation where it does not exercise significant influence.  Because this
investment does not have a readily determinable fair value, the Company has elected to measure this investment at its cost
minus impairments, if any, plus or minus changes resulting from observable price changes in orderly transactions for identical
or similar investments in the private corporation.  The following table summarizes the cost, cumulative unrealized gains, and
carrying amount of investments without readily determinable fair values:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)
Contingent payment obligations represent the fair value of the expected future settlement amounts related to the
Company’s investments in its consolidated Affiliates.  Changes to assumed volatility and discount rates change the fair value of
contingent payment obligations.  Increases to the volatility rates used would result in higher fair values, while increases to the
discount rates used would result in lower fair values.
Affiliate equity purchase obligations include agreements to purchase Affiliate equity and represent the fair value of the
expected future settlement amounts.  Changes to assumed growth rates and discount rates change the fair value of the Affiliate
equity purchase obligations.  Increases to the assumed growth rates would result in higher fair values, while increases to the
discount rates used would result in lower fair values.

The Company has other financial assets and liabilities that are not required to be carried at fair value, but are required to be
disclosed at fair value.  The carrying amount of Cash and cash equivalents, Receivables, Payables and accrued liabilities, and
certain Other liabilities approximates fair value because of the short-term nature of these instruments.  The carrying value of the
credit facilities (as defined in Note 7) approximates fair value because the credit facilities have variable interest based on
selected short-term rates.
6.Investments in Affiliates and Affiliate Sponsored Investment Products
In evaluating whether an investment must be consolidated, the Company evaluates the risk, rewards, and significant terms
of each of its Affiliates and other investments to determine if an investment is considered a voting rights entity (“VRE”) or a
variable interest entity (“VIE”).  An entity is a VRE when the total equity investment at risk is sufficient to enable the entity to
finance its activities independently, and when the equity holders have the obligation to absorb losses, the right to receive
residual returns, and the right to direct the activities of the entity that most significantly impact its economic performance.  An
entity is a VIE when it lacks one or more of the characteristics of a VRE, which, for the Company, are Affiliate investments
structured as partnerships (or similar entities) where the Company is a limited partner and lacks substantive kick-out or
substantive participation rights over the general partner.  Assessing whether an entity is a VRE or VIE involves judgment. 
Upon the occurrence of certain events, management reviews and reconsiders its previous conclusion regarding the status of an
entity as a VRE or a VIE.
The Company consolidates VREs when it has control over significant operating, financial, and investing decisions of the
entity.  When the Company lacks such control, but is deemed to have significant influence, the Company accounts for the VRE
under the equity method.  Investments with readily determinable fair values in which the Company does not have rights to
exercise significant influence are recorded at fair value on the Consolidated Balance Sheets, with changes in fair value included
in Investment and other income.
The Company consolidates VIEs when it is the primary beneficiary of the entity, which is defined as having the power to
direct the activities that most significantly impact the VIE’s economic performance and the obligation to absorb losses of, or the
right to receive benefits from, the entity that could potentially be significant to the VIE.  Substantially all of the Company’s
consolidated Affiliates considered VIEs are controlled because the Company holds a majority of the voting interests or it is the
managing member or general partner.  Furthermore, an Affiliate’s assets can be used for purposes other than the settlement of
the respective Affiliate’s obligations.  The Company applies the equity method of accounting to VIEs where the Company is
not the primary beneficiary, but has the ability to exercise significant influence over operating and financial matters of the VIE.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)
Investments in Affiliates
Substantially all of the Company’s Affiliates are considered VIEs and are either consolidated or accounted for under the
equity method.  A limited number of the Company’s Affiliates are considered VREs and most of these are accounted for under
the equity method.
When an Affiliate is consolidated, the portion of the earnings attributable to Affiliate management’s and any co-investor’s
equity ownership is included in Net income (non-controlling interests) in the Consolidated Statements of Income. 
Undistributed earnings attributable to Affiliate management’s and any co-investor’s equity ownership, along with their share of
any tangible or intangible net assets, are included in Non-controlling interests on the Consolidated Balance Sheets.  Affiliate
equity interests where the holder has certain rights to demand settlement are presented, at their current redemption values, as
Redeemable non-controlling interests or Other liabilities on the Consolidated Balance Sheets.  The Company periodically
issues, sells, and purchases the equity of its consolidated Affiliates.  Because these transactions take place between entities that
are under common control, any gains or losses attributable to these transactions are required to be included in Additional paid-
in capital in the Consolidated Balance Sheets, net of any related income tax effects in the period the transaction occurs.
When an Affiliate is accounted for under the equity method, the Company’s share of an Affiliate’s earnings or losses, net
of amortization and impairments, is included in Equity method income (net) in the Consolidated Statements of Income and the
carrying value of the Affiliate is recorded in Equity method investments in Affiliates (net) in the Consolidated Balance Sheets.
The Company periodically performs assessments to determine if the fair value of an investment may have declined below
its related carrying value for its Affiliates accounted for under the equity method for a period that the Company considers to be
other-than-temporary.  The Company performs these assessments if certain triggering events occur or annually during the
fourth quarter.  The Company first considers whether certain qualitative factors indicate an increased likelihood of a decline in
the fair value of an Affiliate during the reporting period.  If such a decline is identified, and it is likely that an investment’s fair
value may have declined below its carrying value, the Company performs a quantitative assessment to determine if an
impairment exists.  Impairments are recorded as an expense in Equity method income (net) to reduce the carrying value of the
Affiliate to fair value.
The unconsolidated assets, net of liabilities and non-controlling interests of Affiliates accounted for under the equity
method considered VIEs, and the Company’s carrying value and maximum exposure to loss, were as follows:

As of December 31, 2023 and September 30, 2024, the carrying value and maximum exposure to loss for all of the
Company’s Affiliates accounted for under the equity method was $2,288.5 million and $2,148.4 million, respectively, including
Affiliates accounted for under the equity method considered VREs of $90.3 million and $105.7 million, respectively.
Affiliate Sponsored Investment Products
The Company’s Affiliates sponsor various investment products where the Affiliate also acts as the investment adviser. 
These investment products are typically owned primarily by third-party investors; however, certain products are funded with
general partner and seed capital investments from the Company and its Affiliates.
Third-party investors in Affiliate sponsored investment products are generally entitled to substantially all of the economics
of these products, except for the asset- and performance-based fees earned by the Company’s Affiliates or any gains or losses
attributable to the Company’s or its Affiliates’ investments in these products.  As a result, the Company generally does not
consolidate these products.  However, for certain products, the Company’s consolidated Affiliates, as the investment manager,
have the power to direct the activities of the investment product and have an exposure to the economics of the VIE that is more
than insignificant, though generally only for a short period while the product is established and has yet to attract significant
third-party investors.  When the products are consolidated, the Company retains the specialized investment company accounting
principles of the underlying products, and all of the underlying investments are carried at fair value in Investments in
marketable securities, with corresponding changes in the investments’ fair values included in Investment and other income. 
Purchases and sales of securities are included in purchases and sales by consolidated Affiliate sponsored investment products in

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)
the Consolidated Statements of Cash Flows, respectively, and the third-party investors’ interests are recorded in Redeemable
non-controlling interests.  When the Company or its consolidated Affiliates no longer control these products, due to a reduction
in ownership or other reasons, the products are deconsolidated with only the Company’s or its consolidated Affiliate’s
investment in the product reported from the date of deconsolidation.
The Company’s carrying value and maximum exposure to loss from unconsolidated Affiliate sponsored investment
products, is its or its consolidated Affiliates’ interests in the unconsolidated net assets of the respective products.  The net assets
of unconsolidated VIEs attributable to Affiliate sponsored investment products, and the Company’s carrying value and
maximum exposure to loss, were as follows:

exception of its senior unsecured multicurrency revolving credit facility (the “revolver”), are presented on the Consolidated
Balance Sheets as an adjustment to the carrying value of the associated debt.
Senior Bank Debt
During the nine months ended September 30, 2024, the Company repaid the $350.0 million outstanding under its senior
unsecured term loan facility (the “term loan”).
As of September 30, 2024, the Company had a $1.25 billion revolver (together with the term loan, the “credit facilities”). 
The revolver matures on October 25, 2027 and the term loan terminated upon payment in full.  Subject to certain conditions, the
Company may increase the commitments under the revolver by up to an additional $500.0 million.  The Company pays interest
on any outstanding obligations under the revolver at a specified rate, currently based either on an applicable term-SOFR plus a
SOFR adjustment of 0.10%, or prime rate, plus a marginal rate determined based on its credit rating.  Through the repayment
dates, the interest rate for the Company’s outstanding borrowings under the term loan was term-SOFR plus a SOFR adjustment
of 0.10%, plus the marginal rate of 0.85%.  As of December 31, 2023 and September 30, 2024, the Company had no
outstanding borrowings under the revolver.
Senior Notes
In the first quarter of 2024, the Company’s $400.0 million 4.25% senior notes matured and were fully repaid.
As of September 30, 2024, the Company had senior notes outstanding.  The carrying values of the senior notes are accreted
to their principal amount at maturity over the remaining life of the underlying instrument.  The principal terms of the senior
notes outstanding as of September 30, 2024 are presented and described below:

On August 20, 2024, the Company issued $400.0 million aggregate principal amount of senior unsecured notes with a
maturity date of August 20, 2034 (the “2034 senior notes”).  Interest is payable beginning February 20, 2025.  In addition to
customary event of default provisions, the indenture governing the 2034 senior notes limits the Company's ability to
consolidate, merge, or sell all or substantially all of its assets and requires the Company to make an offer to repurchase the 2034
senior notes upon certain change of control triggering events.
The senior notes may be redeemed, in whole or in part, at a make-whole redemption price (plus accrued and unpaid
interest), at any time, in the case of the 2025 senior notes, at any time prior to March 15, 2030, in the case of the 2030 senior
notes, and at any time prior to May 20, 2034, in the case of the 2034 senior notes.  The make-whole redemption price, in each
case, is equal to the greater of 100% of the principal amount of the notes to be redeemed and the remaining principal and
interest payments on the notes being redeemed (excluding accrued but unpaid interest to, but not including, the redemption
date) discounted to their present value as of the redemption date at the applicable treasury rate plus 0.25%, in the case of the
2025 and 2034 senior notes, and to their present value as of the redemption date on a semi-annual basis at the applicable
treasury rate plus 0.40%, in the case of the 2030 senior notes.  In addition, the 2030 and 2034 senior notes may be redeemed, in
whole or in part, at any time, on or after March 15, 2030 and May 20, 2034, respectively, at a redemption price equal to 100%
of the principal amount of the notes to be redeemed plus accrued and unpaid interest thereon to, but not including, the
redemption date.

On March 20, 2024, the Company issued $450.0 million of junior subordinated notes with a maturity date of March 30,
2064 (the “2064 junior subordinated notes”).  Interest was payable beginning June 30, 2024.  The 2064 junior subordinated
notes were issued at 100% of the principal amount and rank junior and subordinate in right of payment and upon liquidation to
all of the Company’s current and future senior indebtedness.  As of September 30, 2024, the 2059 junior subordinated notes
could be redeemed at any time, in whole or in part.  The other junior subordinated notes may be redeemed at any time, in whole
or in part, on or after September 30, 2025, in the case of the 2060 junior subordinated notes, on or after September 30, 2026, in
the case of the 2061 junior subordinated notes, and on or after March 30, 2029, in the case of the 2064 junior subordinated
notes.  In each case, the junior subordinated notes may be redeemed at 100% of the principal amount of the notes being
redeemed, plus any accrued and unpaid interest thereon.  Prior to the applicable redemption date, at the Company’s option, the
applicable junior subordinated notes may also be redeemed, in whole but not in part, at 100% of the principal amount, plus any
accrued and unpaid interest, if certain changes in tax laws, regulations, or interpretations occur; or at 102% of the principal

amount, plus any accrued and unpaid interest, if a rating agency makes certain changes relating to the equity credit criteria for
securities with features similar to the applicable notes.
The Company may, at its option, and subject to certain conditions and restrictions, defer interest payments subject to the
terms of the junior subordinated notes.
Junior Convertible Securities
As of September 30, 2024, the Company had $341.7 million of principal outstanding in its 5.15%  junior convertible trust
preferred securities (the “junior convertible securities”), maturing in 2037.  The junior convertible securities bear interest at a
rate of 5.15% per annum, payable quarterly in cash.
As of December 31, 2023 and September 30, 2024, the unamortized issuance costs related to the junior convertible
securities were $2.9 million and $2.7 million, respectively.
The following table presents interest expense recorded in connection with the junior convertible securities:

Holders of the junior convertible securities have no rights to put these securities to the Company.  The holder may convert
the securities to 0.2558 shares of common stock per $50.00 junior convertible security, equivalent to an adjusted conversion
price of $195.47 per share.  The conversion rate is subject to adjustments as described in the Amended and Restated Declaration
of Trust of AMG Capital Trust II and the related indenture, both dated October 17, 2007 and filed as exhibits to the Company’s
most recent Annual Report on Form 10-K.  Upon conversion, holders will receive cash or shares of the Company’s common
stock, or a combination thereof, at the Company’s election.  The Company may redeem the junior convertible securities if the
closing price of its common stock for 20 trading days in a period of 30 consecutive trading days exceeds 130% of the then
prevailing conversion price, and may also repurchase junior convertible securities in the open market or in privately negotiated
transactions from time to time at management’s discretion.  The Company did not repurchase any of its junior convertible
securities during the nine months ended September 30, 2023 and 2024.
8.Commitments and Contingencies
From time to time, the Company and its Affiliates may be subject to claims, legal proceedings, and other contingencies in
the ordinary course of their business activities.  Any such matters are 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, as necessary, for matters for which the outcome is probable and the amount of the liability can be
reasonably estimated.
The Company has committed to co-invest in certain Affiliate sponsored investment products.  As of September 30, 2024,
these unfunded commitments were $215.7 million and may be called in future periods.
As of September 30, 2024, the Company was obligated to make deferred payments and was contingently liable to make
payments in connection with certain of its consolidated Affiliates, which are included in Other liabilities, as follows:

Veritable Transaction
In the third quarter of 2023, the Company completed the sale of its equity interest in Veritable, LP (“Veritable”), one of the
Company’s consolidated Affiliates.  Pursuant to the terms of the agreement, under which a third party acquired 100% of the
outstanding equity interests in Veritable, the Company received $287.4 million in cash, net of transaction costs.  Veritable was
included in the Company’s results through the closing date, and the Company’s gain on the transaction was $133.1 million,
which was recorded in Affiliate Transaction gain in the Consolidated Statements of Income.
10.Equity Method Investments in Affiliates
In the second quarter of 2024, the Company completed its minority investment in Suma Capital (“Suma”), a pan-
European private markets firm that invests in the transition to a lower carbon economy.  Following the close of the
transaction, Suma partners continue to hold a significant majority of the equity of the firm and direct its day-to-day
operations.
The financial results of certain Affiliates accounted for under the equity method are recognized in the Consolidated
Financial Statements one quarter in arrears.

Definite-lived acquired client relationships at the Company’s Affiliates accounted for under the equity method are
amortized over their expected period of economic benefit.  The Company recorded amortization expense for these relationships
of $21.2 million and $63.0 million for the three and nine months ended September 30, 2023, respectively, and $22.7 million and
$64.4 million for the three and nine months ended September 30, 2024, respectively.  Based on relationships existing as of
September 30, 2024, the Company estimates the amortization expense attributable to its Affiliates will be approximately $23
million for the remainder of 2024, approximately $75 million in 2025, approximately $70 million in each of 2026 and 2027,
approximately $60 million in 2028, and approximately $45 million in 2029.
In the second quarter of 2024, the Company recorded a $39.9 million expense to reduce the carrying value of an Affiliate to
fair value.  The decline in the fair value was a result of an anticipated decline in assets under management, which decreased the
forecasted income associated with the investment.  The fair value of the investment was determined using a discounted cash
flow analysis, a Level 3 fair value measurement that included a projected compounded growth in assets under management over
the next ten years of (2.5)%, long-term growth rate of 3%, discount rates of 12% and 20% for asset- and performance-based
fees, respectively, and a market participant tax rate of 21%.  Based on the discounted cash flow analysis, the Company
20
Table of Contents
AFFILIATED MANAGERS GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)
concluded that the fair value of its investment had declined below its carrying value and that the decline was other-than-
temporary.
The Company had 22 Affiliates accounted for under the equity method as of December 31, 2023 and September 30,
2024.  The majority of these Affiliates are partnerships with structured interests that define how the Company will
participate in Affiliate earnings, typically based upon a fixed percentage of revenue reduced by, in some cases, certain
agreed-upon expenses.  The partnership agreements do not define a fixed percentage for the Company’s ownership of the
equity of the Affiliate.  These percentages would be subject to a separate future negotiation if an Affiliate were to be sold
or liquidated.
11.Related Party Transactions
A prior owner of one of the Company’s consolidated Affiliates retains interests in certain of the Affiliate’s private equity
partnerships and, as a result, is a related party of the Company.  The prior owner’s interests are included in Other liabilities and
were $18.5 million and $15.0 million as of December 31, 2023 and September 30, 2024, respectively.
The Company may invest from time to time in funds or products advised by its Affiliates.  The Company’s executive
officers and directors may invest from time to time in funds advised or products offered by its Affiliates, or receive other
investment services provided by its Affiliates, on substantially the same terms as other participating investors.  In addition, the
Company and its Affiliates earn asset- and performance-based fees and incur distribution and other expenses for services
provided to Affiliate sponsored investment products.  Affiliate management owners and the Company’s officers may serve as
trustees or directors of certain investment vehicles from which the Company or an Affiliate earns fees.  Also, from time to time,
the Company may enter into ordinary course engagements for capital markets, banking, brokerage, and other services with
beneficial owners of 5% or more of the Company’s voting securities.
The Company has related party transactions in association with its deferred and contingent payment obligations, and
Affiliate equity transactions, as more fully described in Notes 8, 13, and 14.

The Company did not grant any stock options during the nine months ended September 30, 2023 and 2024.  Stock options
generally vest over a period of three years to five years and expire seven years after the grant date.  All stock options have been
granted with exercise prices equal to the closing price of the Company’s common stock on the grant date.  Substantially all of
the Company’s outstanding stock options contain both service and performance conditions.  For awards with performance
conditions, the number of stock options expected to vest may change over time depending upon the performance level achieved.
13.Redeemable Non-Controlling Interests
Affiliate equity interests provide holders with an equity interest in one of the Company’s Affiliates, consistent with the
structured partnership interests in place at the respective Affiliate.  Affiliate equity holders generally have a conditional right to
put their interests to the Company at certain intervals (between five years and 15 years from the date the equity interest is
received by the Affiliate equity holder or on an annual basis following an Affiliate equity holder’s departure).  Prior to
becoming redeemable, the Company’s Affiliate equity is included in Non-controlling interests.  Upon becoming redeemable,
these interests are reclassified to Redeemable non-controlling interests at their current redemption values.  Changes in the
current redemption value are recorded to Additional paid-in capital.  When the Company has an unconditional obligation to
purchase Affiliate equity interests, the interests are reclassified from Redeemable non-controlling interests to Other liabilities at
current fair value.  Changes in fair value are recorded to Other expenses (net).
The following table presents the changes in Redeemable non-controlling interests:

AFFILIATED MANAGERS GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)
(1)As of December 31, 2023 and September 30, 2024, Redeemable non-controlling interests include consolidated Affiliate
sponsored investment products primarily attributable to third-party investors of $11.8 million and $13.3 million,
respectively.
14.Affiliate Equity
Affiliate equity interests are allocated income in a manner that is consistent with the structured partnership interests in
place at the respective Affiliate.  The Company’s Affiliates generally pay quarterly distributions to Affiliate equity holders. 
Distributions paid to non-controlling interest Affiliate equity holders were $216.4 million and $206.5 million for the nine
months ended September 30, 2023 and 2024, respectively.
The Company periodically purchases Affiliate equity from and issues Affiliate equity to the Company’s consolidated
Affiliate partners and other parties under agreements that provide the Company a conditional right to call and Affiliate equity
holders the conditional right to put their Affiliate equity interests to the Company at certain intervals.  The Company has the
right to settle a portion of these purchases in shares of its common stock.  For Affiliates accounted for under the equity method,
the Company does not typically have such put and call arrangements.  For the nine months ended September 30, 2023 and
2024, the amount of cash paid for purchases was $41.7 million and $60.4 million, respectively.  For the nine months ended
September 30, 2023 and 2024, the total amount of cash received for issuances was $13.4 million and $6.3 million, respectively.
Sales and purchases of Affiliate equity generally occur at fair value; however, the Company also grants Affiliate equity to
its consolidated Affiliate partners and other parties as a form of compensation.  If the equity is issued for consideration below
the fair value of the equity, or purchased for consideration above the fair value of the equity, the difference is recorded as
compensation expense in Compensation and related expenses in the Consolidated Statements of Income over the requisite
service period.

The Company records amounts receivable from, and payable to, Affiliate equity holders in connection with the transfer of
Affiliate equity interests that have not settled at the end of the period.  The total receivable was $5.9 million and $4.5 million as
of December 31, 2023 and September 30, 2024, respectively, and was included in Other assets on the Consolidated Balance
Sheets.  The total payable was $53.9 million and $58.9 million as of December 31, 2023 and September 30, 2024, respectively,
and was included in Other liabilities.
Effects of Changes in the Company’s Ownership in Affiliates
The Company periodically acquires interests from, and transfers interests to, Affiliate equity holders.  Because these
transactions do not result in a change of control, any gain or loss related to these transactions is recorded to Additional paid-in
capital, which increases or decreases the controlling interest’s equity.  No gain or loss related to these transactions is recorded in
the Consolidated Statements of Income or the Consolidated Statements of Comprehensive Income.
While the Company presents the current redemption value of Affiliate equity within Redeemable non-controlling interests,
with changes in the current redemption value increasing or decreasing the controlling interest’s equity over time, the following
table presents the cumulative effect that ownership changes had on the controlling interest’s equity related only to Affiliate
equity transactions that occurred during the applicable periods:

(1)For the three months ended September 30, 2023 and 2024, income tax expense (controlling interest) included intangible-
related deferred tax (benefit) expense of $(13.5) million and $16.4 million, respectively.  For the nine months ended
September 30, 2023 and 2024, income tax expense (controlling interest) included intangible-related deferred tax expense of
$16.4 million and $50.6 million, respectively.
(2)Taxes attributable to the controlling interest divided by income before income taxes (controlling interest).
The Company’s effective tax rate (controlling interest) for the three months ended September 30, 2023 was higher than the
marginal tax rate of 24.5%, primarily due to the increase in the UK corporate tax rate in 2023.  The Company’s effective tax
rate (controlling interest) for the nine months ended September 30, 2023 was lower than the marginal tax rate primarily due to
discrete foreign tax benefits and tax windfalls attributable to share-based compensation.
The Company’s effective tax rate (controlling interest) for the three months ended September 30, 2024 was lower than the
marginal tax rate of 24.5%, primarily due to tax windfalls attributable to share-based compensation.  The Company’s effective
tax rate (controlling interest) for the nine months ended September 30, 2024 was higher than the marginal tax rate of 24.5%,
primarily due to an expense to reduce the carrying value of an Affiliate to fair value for which no tax benefit was recorded.
The Company’s effective tax rate reflects the relative contributions of earnings in the jurisdictions in which the Company
and its Affiliates operate and is impacted by changes in the jurisdictional mix of income before taxes.
The Company continues to monitor and evaluate legislative developments related to the Organization for Economic Co-
operation and Development’s Pillar Two directive (“Pillar Two”), which establishes a framework for a global minimum
corporate tax rate of 15%.  Several countries in which the Company or its Affiliates operate have adopted legislation to
implement Pillar Two and several others are expected to enact similar rules in the future.  The Company currently does not
expect Pillar Two to have a material impact on its Consolidated Financial Statements.

16.Earnings Per Share
The calculation of Earnings per share (basic) is based on the weighted average number of shares of the Company’s
common stock outstanding during the period.  Earnings per share (diluted) is similar to Earnings per share (basic), 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

Executive Overview
AMG is a strategic partner to leading independent investment firms globally.  Our strategy is to generate long-term value
by investing in a diverse array of high-quality independent partner-owned firms, referred to as “Affiliates,” through a proven
partnership approach, and allocating resources across our unique opportunity set to the areas of highest growth and return. 
With their entrepreneurial, investment-centric cultures and alignment of interests with clients through direct equity ownership
by firm principals, independent firms have fundamental competitive advantages in offering unique return streams to the
marketplace.  Through AMG’s distinctive approach, we enhance these advantages to magnify the long-term success of our
Affiliates and actively support their independence.  Our innovative model enables each Affiliate’s management team to retain
autonomy and significant equity ownership in their firm, while they leverage our strategic capabilities and insight, including
growth capital, product strategy and development, capital formation, and incentive alignment and succession planning.  As of
September 30, 2024, our aggregate assets under management were approximately $728 billion across a diverse range of
private markets, liquid alternatives, and differentiated long-only investment strategies.
In the second quarter of 2024, we completed our minority investment in Suma Capital (“Suma”), a pan-European private
markets firm that invests in the transition to a lower carbon economy.  Following the close of the transaction, Suma partners
continue to hold a significant majority of the equity of the firm and direct its day-to-day operations.
Operating Performance Measures
Under accounting principles generally accepted in the U.S. (“GAAP”), we are required to consolidate certain of our
Affiliates and use the equity method of accounting for others.  Whether we consolidate an Affiliate or use the equity method of
accounting, we maintain the same innovative partnership approach and provide support and assistance in substantially the same
manner for all of our Affiliates.  Furthermore, all of our Affiliates are investment managers and are impacted by similar
marketplace factors and industry trends.  Therefore, our key aggregate operating performance measures are important in
providing management with a comprehensive view of the operating performance and material trends across our entire business.

Assets under management, and therefore average assets under management, include the assets under management of our
consolidated and equity method Affiliates.  Assets under management is presented on a current basis without regard to the
timing of the inclusion of an Affiliate’s financial results in our operating performance measures and Consolidated Financial
Statements.  Average assets under management reflects the timing of the inclusion of an Affiliate’s financial results in our
operating performance measures and Consolidated Financial Statements.  Average assets under management for mutual funds
and similar investment products generally represents an average of the daily net assets under management, while for
institutional and high net worth clients, average assets under management generally represents an average of the assets at the
beginning or end of each month during the applicable period.
Aggregate fees consist of the total asset- and performance-based fees earned by all of our consolidated and equity method
Affiliates.  For certain of our Affiliates accounted for under the equity method, we report the Affiliate’s aggregate fees one
quarter in arrears.  Aggregate fees are provided in addition to, but not as a substitute for, Consolidated revenue or other GAAP
performance measures.
Assets Under Management
Our Affiliates provide a diverse range of differentiated return streams through their specialized investment processes.  We
continue to see client demand for alternative strategies, as evidenced by our net inflows in this category for the three and nine
months ended September 30, 2024.  At the same time, our equity strategies saw outflows in line with client cash flow trends
across the industry.  We continue to invest our capital and resources in areas aligned with long-term client demand trends, most
notably in private markets and liquid alternatives.  As we continue to invest in new and existing Affiliates, we expect to further
evolve our business mix and better position AMG to benefit from industry growth trends.  We also anticipate that independent
investment firms will continue to seek access to an evolving range of partnership solutions, and that we have a significant
opportunity to invest in additional high-quality firms across the global investment management industry.
The following charts present information regarding the composition of our assets under management by strategy and client
type as of September 30, 2024:

___________________________
(1)Past performance is not indicative of future results.  Performance and AUM information is as of September 30, 2024 and is
based on data available at the time of calculation.  Product returns are sourced from Affiliates while benchmark returns are
generally sourced via third-party subscriptions. 
(2)For liquid alternative, global equity, and U.S. equity products, performance is reported as the percentage of assets that have
outperformed benchmarks across the indicated periods, and excludes market-hedging products.  For purposes of investment
performance comparisons, products are an aggregation of portfolios (separate accounts, investment funds, and other
products) that each represent a particular investment objective, using the most representative portfolio for the performance
comparison.  Performance is presented for products with a three-, five-, and/or ten-year track record and is measured on a
consistent basis relative to the most appropriate benchmarks.  Benchmark appropriateness is generally reviewed annually to
reflect any changes in how underlying portfolios/mandates are managed.  Product and benchmark performance is reflected
as total return and is annualized.  Reported product performance is gross-of-fees for institutional and high-net-worth
separate accounts, and generally net-of-fees across retail funds and other commingled vehicles such as hedge funds.
(3)Multi-asset and fixed income products are mainly our wealth management and solutions offerings.  These investment
products are primarily customized toward wealth preservation, estate planning, and liability and tax management, and
therefore are typically not measured against a benchmark.
30
Table of Contents
(4)For private markets products, performance is reported as the percentage of assets that have outperformed benchmarks on a
since-inception internal rate of return basis.  Benchmarks utilized include a combination of public market equivalents, peer
medians, and absolute returns where benchmarks are not available.  For purposes of investment performance comparisons,
the latest vintage comparison includes the most recent vehicles and strategies (traditional long-duration investment funds,
customized vehicles, and other evergreen vehicles and product structures) where meaningful performance is available and
calculable.  In order to illustrate the performance of our private markets product category over a longer period of history,
the last three vintages comparison incorporates the latest vintage vehicles and the prior two vintages for traditional long-
duration investment funds, as well as additional vehicles and strategies launched during the equivalent time period as the
last three vintages of traditional long-duration investment funds.  Due to the nature of these investments and vehicles,
reported performance is typically on a three- to six-month lag basis.
Aggregate Fees
Aggregate fees consist of asset- and performance-based fees of our consolidated and equity method Affiliates.  Asset-based
fees include advisory and other fees earned by our Affiliates for services provided to their clients and are typically determined
as a percentage of the value of a client’s assets under management, generally inclusive of uncalled commitments.  Asset-based
fees are generally impacted by the level of average assets under management and the composition of these assets across our
strategies with different asset-based fee ratios.  Our asset-based fee ratio is calculated as asset-based fees divided by average
assets under management.
In some cases, if product returns exceed certain performance thresholds, we will participate in performance-based fees. 
Performance-based fees are based on investment performance, typically on an absolute basis or relative to a benchmark or a
hurdle rate, and are generally recognized when it is improbable that there will be a significant reversal in the amount of revenue
recognized.  Performance-based fees are generally billed less frequently than asset-based fees and will vary from period to
period because they inherently depend on investment performance.  As of September 30, 2024, approximately 27% of our total
assets under management could potentially earn performance-based fees.  These percentages were approximately 12% and 46%
of our assets under management for our consolidated Affiliates and Affiliates accounted for under the equity method,
respectively.  We anticipate performance-based fees will be a recurring component of our aggregate fees; however we do not
anticipate these fees to be a significant component of our Consolidated revenue as these fees are predominately earned by our
Affiliates accounted for under the equity method.
Aggregate fees were $1,157.1 million for the three months ended September 30, 2024, an increase of $159.6 million or
16% as compared to the three months ended September 30, 2023.  The increase in our aggregate fees was due to a $97.2 million
or 10% increase from asset-based fees and a $62.4 million or 6% increase from performance-based fees, primarily in our liquid
alternatives strategies.  The increase in asset-based fees was principally due to an increase in our average assets under
management, primarily in our alternatives strategies, and changes in the composition of our assets under management primarily
driven by investments in new Affiliates.
Aggregate fees were $3,726.8 million for the nine months ended September 30, 2024, an increase of $221.1 million or 6%
as compared to the nine months ended September 30, 2023.  The increase in our aggregate fees was due to a $245.7 million or
7% increase from asset-based fees, offset by a $24.6 million or 1% decrease from performance-based fees, primarily in our
liquid alternatives strategies.  The increase in asset-based fees was principally due to an increase in our average assets under
management, primarily in our alternatives strategies, and changes in the composition of our assets under management primarily
driven by investments in new Affiliates.

measures and are discussed in “Supplemental Financial Performance Measures.”
31
Table of Contents
Adjusted EBITDA (controlling interest) is an important supplemental financial performance measure for management. 
Our Adjusted EBITDA (controlling interest) increased $5.7 million or 3% in the three months ended September 30, 2024
primarily due to a $159.6 million or 16% increase in aggregate fees.  Adjusted EBITDA increased less than aggregate fees on a
percentage basis primarily due to the recognition of performance-based fees earned by Affiliates in which we hold a lesser
economic interest.
For the nine months ended September 30, 2024, our Adjusted EBITDA (controlling interest) increased $51.8 million or
8%, primarily from investments in new Affiliates and the recognition of performance-based fees earned by Affiliates in which
we hold a greater economic interest.
For the three months ended September 30, 2024, our Net income (controlling interest) decreased $93.4 million or 43%. 
This decrease was primarily due to the recognition of a $133.1 million pre-tax gain associated with the sale of our equity
interest in Veritable, LP (“Veritable”) in the third quarter of 2023 (the “Veritable Transaction”), partially offset by a $46.4
million decrease in Income tax expense attributable to the controlling interest.
For the nine months ended September 30, 2024, our Net income (controlling interest) decreased $127.3 million or 27%. 
This decrease was primarily due to the recognition of a $133.1 million pre-tax gain associated with the Veritable Transaction in
the third quarter of 2023 and a $30.4 million decrease in Investment and other income attributable to the controlling interest. 
These decreases were partially offset by a $26.2 million decrease in Income tax expense attributable to the controlling interest.
We believe Economic net income (controlling interest) is an important supplemental financial performance measure
because it represents our performance before non-cash expenses relating to the acquisition of interests in Affiliates and
improves comparability of performance between periods.  For the three months ended September 30, 2024, our Economic net
income (controlling interest) increased $3.7 million or 2%, primarily due to a $5.7 million increase in Adjusted EBITDA
(controlling interest), partially offset by a $3.6 million increase in Interest expense attributable to the controlling interest.
For the nine months ended September 30, 2024, our Economic net income (controlling interest) increased $20.9 million or
4%, primarily due to a $51.8 million increase in Adjusted EBITDA (controlling interest).  This increase was partially offset by
a $26.2 million increase in current and other deferred taxes attributable to the controlling interest and a $5.7 million increase in
Interest expense attributable to the controlling interest.
Results of Operations
The following discussion includes the key operating performance measures and financial results of our consolidated and

private markets strategies.  The decrease in asset-based fees was principally due to changes in the composition of our assets
under management driven by the Veritable Transaction, offset by an increase in our consolidated Affiliate average assets under
management, primarily in our alternatives strategies.
Our Consolidated revenue decreased $38.6 million or 2% for the nine months ended September 30, 2024, primarily due to
a $39.2 million or 2% decrease from asset-based fees.  The decrease in asset-based fees was principally due to changes in the
composition of our assets under management driven by the Veritable Transaction and a decrease in our consolidated Affiliate
average assets under management, primarily in our global equity strategies.

Compensation and related expenses increased $9.0 million or 4% for the three months ended September 30, 2024,
primarily due to a $13.6 million increase in compensation accruals at Affiliates, partially offset by a decrease in compensation
and related expenses due to the Veritable Transaction.
Compensation and related expenses increased $13.5 million or 2% for the nine months ended September 30, 2024,
primarily due to a $21.9 million increase in compensation accruals primarily at Affiliates and a $7.0 million increase in Affiliate
equity compensation expense.  These increases were partially offset by a decrease in compensation and related expenses due to
the Veritable Transaction.
Selling, general and administrative expenses increased $5.9 million or 6% for the three months ended September 30, 2024,
primarily due to a $3.3 million increase in professional fees and a $2.4 million increase in distribution and investment-related
expenses, principally as a result of the increase in average assets under management on which these expenses are incurred.
Selling, general and administrative expenses increased $4.7 million or 2% for the nine months ended September 30, 2024,
primarily due to a $7.3 million increase in distribution and investment-related expenses, principally as a result of the increase in
average assets under management on which these expenses are incurred.  This increase was partially offset by a $1.3 million
decrease in non-income based and other taxes.
Intangible amortization and impairments decreased $5.2 million or 42% for the three months ended September 30, 2024,
primarily due to a $3.6 million decrease in amortization expense related to certain definite-lived assets being fully amortized
and a $1.7 million decrease due to the Veritable Transaction.
Intangible amortization and impairments decreased $15.7 million or 42% for the nine months ended September 30, 2024,
primarily due to a $10.6 million decrease in amortization expense related to certain definite-lived assets being fully amortized
and a $5.0 million decrease due to the Veritable Transaction.
Interest expense increased $3.6 million or 12% for the three months ended September 30, 2024, primarily due to a $7.6
million increase from our 6.75% junior subordinated notes issued in March 2024 (the “2064 junior subordinated notes”) and a
$2.5 million increase from our 5.50% senior unsecured notes issued in August 2024 (the “2034 senior notes”).  This increase
was partially offset by a $4.4 million decrease due to the maturity of our 4.25% senior notes in February 2024 (the “2024 senior
notes”) and a $2.8 million decrease due to the repayment of our senior unsecured term loan facility (the “term loan”).
Interest expense increased $5.7 million or 6% for the nine months ended September 30, 2024, primarily due to a $16.1
million increase from our 2064 junior subordinated notes and a $2.5 million increase from our 2034 senior notes.  This increase
was partially offset by an $11.1 million decrease due to the maturity of our 2024 senior notes in February 2024 and a $2.5
million decrease primarily due to the repayment of our term loan.
There were no significant changes to Depreciation and other amortization for the three and nine months ended
September 30, 2024.
Other expenses (net) increased $3.7 million or 47% for the three months ended September 30, 2024, primarily due to a $3.8
million increase in expenses related to changes in the values of contingent payment obligations.
33
Table of Contents
Other expenses (net) decreased $4.7 million or 13% for the nine months ended September 30, 2024, primarily due to a $5.4
million decrease in expenses related to changes in the values of contingent payment obligations.
Equity Method Income (Net)
For our Affiliates accounted for under the equity method, we use structured partnership interests in which we contractually
share in the Affiliate’s revenue or revenue less agreed-upon expenses.  Our share of earnings or losses from Affiliates

(1)Percentage change is not meaningful.
Our equity method revenue increased $168.4 million or 36% for the three months ended September 30, 2024, due to a
$109.1 million or 23% increase from asset-based fees and a $59.3 million or 13% increase from performance-based fees,
primarily in our liquid alternatives strategies.  The increase in asset-based fees was principally due to an increase in our equity
method Affiliate average assets under management, primarily in our alternatives strategies, and changes in the composition of
our assets under management primarily driven by investments in new Affiliates.
For the three months ended September 30, 2024, equity method earnings increased $14.3 million or 23%, primarily due to
a $168.4 million or 36% increase in equity method revenue.  Equity method earnings increased less than equity method revenue
on a percentage basis primarily due to the recognition of performance-based fees earned by Affiliates in which we hold a lesser
economic interest and an increase in revenue at certain Affiliates in which we share in revenue less agreed-upon expenses.
Equity method intangible amortization increased $1.5 million or 7% for the three months ended September 30, 2024,
primarily due to a $5.3 million increase in amortization expense due to investments in new Affiliates and a $4.5 million
increase in amortization expense due to an increase in actual and expected client attrition for certain definite-lived acquired
client relationships.  These increases were partially offset by an $8.3 million decrease in amortization expense related to certain
definite-lived assets being fully amortized.
Our equity method revenue increased $259.7 million or 13% for the nine months ended September 30, 2024, due to a
$284.9 million or 14% increase from asset-based fees, offset by a $25.2 million or 1% decrease from performance-based fees,
primarily in our liquid alternatives strategies.  The increase in asset-based fees was principally due to an increase in our equity
method Affiliate average assets under management, primarily in our alternatives strategies, and changes in the composition of
our assets under management primarily driven by investments in new Affiliates.
For the nine months ended September 30, 2024, equity method earnings increased $75.3 million or 35%, primarily due to a
$259.7 million or 13% increase in equity method revenue.  Equity method earnings increased more than equity method revenue
on a percentage basis primarily due to an increase in earnings at certain Affiliates in which we share in revenue less agreed-
upon expenses and the recognition of performance-based fees earned by Affiliates in which we hold a greater economic interest.

Equity method intangible amortization increased $1.4 million or 2% for the nine months ended September 30, 2024,
primarily due to a $15.8 million increase in amortization expense due to investments in new Affiliates and a $10.5 million
increase in amortization expense due to an increase in actual and expected client attrition for certain definite-lived acquired
client relationships.  These increases were partially offset by a $24.9 million decrease in amortization expense related to certain
definite-lived assets being fully amortized.
Equity method intangible impairments increased $39.9 million for the nine months ended September 30, 2024.  See Note

Our consolidated income tax provision includes taxes attributable to the controlling interest and, to a lesser extent, taxes
attributable to the non-controlling interests.
Income tax expense decreased $46.4 million or 60% for the three months ended September 30, 2024.  Our effective tax rate
(controlling interest) for the three months ended September 30, 2024 was 19.3% as compared to 25.9% for the three months
ended September 30, 2023.  The decrease in the tax rate (controlling interest) was primarily due to tax windfalls attributable to
share-based compensation in the three months ended September 30, 2024.
Income tax expense decreased $25.4 million or 16% for the nine months ended September 30, 2024.  Our effective rate
(controlling interest) for the nine months ended September 30, 2024 was 26.1% as compared to 23.9% for the nine months
ended September 30, 2023.  The increase in the tax rate (controlling interest) was primarily due to discrete foreign tax benefits
and tax windfalls attributable to share-based compensation in the nine months ended September 30, 2023, and an expense to
reduce the carrying value of an Affiliate to fair value for which no tax benefit was recorded, partially offset by higher tax
windfalls attributable to share-based compensation in the nine months ended September 30, 2024.

decrease in Income tax expense attributable to the controlling interest.
Supplemental Financial Performance Measures
As supplemental information, we provide non-GAAP performance measures of Adjusted EBITDA (controlling interest),
Economic net income (controlling interest), and Economic earnings per share.  We believe that many investors use our
Adjusted EBITDA (controlling interest) when comparing our financial performance to other companies in the investment
management industry.  Management utilizes these non-GAAP performance measures to assess our performance before our
share of certain non-cash GAAP expenses primarily related to the acquisition of interests in Affiliates and to improve
comparability between periods.  Economic net income (controlling interest) and Economic earnings per share are used by
management and our Board of Directors as our principal performance benchmarks, including as one of the measures for
determining executive compensation.  These non-GAAP performance measures are provided in addition to, but not as a
substitute for, Net income (controlling interest), Earnings per share, or other GAAP performance measures.
Adjusted EBITDA (controlling interest)
Adjusted EBITDA (controlling interest) represents our performance before our share of interest expense, income and
certain non-income based taxes, depreciation, amortization, impairments, gains and losses related to Affiliate Transactions, and
non-cash items such as certain Affiliate equity activity, gains and losses on our contingent payment obligations, and unrealized
gains and losses on seed capital, general partner commitments, and other strategic investments.  Adjusted EBITDA (controlling
interest) is also adjusted to include realized economic gains and losses related to these seed capital, general partner
commitments, and other strategic investments.

(2)The three and nine months ended September 30, 2023 includes Veritable Transaction gain of $133.1 million and gains of
$6.5 million and $29.6 million on ordinary shares of EQT AB (“EQT”), a public company listed on Nasdaq Stockholm
(EQT.ST), respectively.  We received the EQT shares through the sale of our equity interest in Baring Private Equity Asia
(“BPEA”), in connection with the strategic combination of BPEA and EQT, which was completed in the fourth quarter of
2022.
(3)Other items include certain non-income based taxes, depreciation, and non-cash items such as certain Affiliate equity
activity, gains and losses on our contingent payment obligations, unrealized gains and losses on seed capital, general
partner commitments, and other strategic investments, and realized economic gains and losses related to these seed capital,
general partner commitments, and other strategic investments.
Economic Net Income (controlling interest) and Economic Earnings Per Share
Under our Economic net income (controlling interest) definition, we adjust Net income (controlling interest) for our share
of pre-tax intangible amortization and impairments related to intangible assets (including the portion attributable to equity
method investments in Affiliates) because these expenses do not correspond to the changes in the value of these assets, which
do not diminish predictably over time.  We also adjust for deferred taxes attributable to intangible assets because we believe it
is unlikely these accruals will be used to settle material tax obligations.  Further, we adjust for gains and losses related to
Affiliate Transactions, net of tax, and other economic items. 
Economic earnings per share represents Economic net income (controlling interest) divided by the Average shares
outstanding (adjusted diluted).  In this calculation, we exclude the potential shares issued upon settlement of Redeemable non-
controlling interests from Average shares outstanding (adjusted diluted) because we intend to settle those obligations without
issuing shares, consistent with all prior Affiliate equity purchase transactions.  The potential share issuance in connection with
our junior convertible securities is measured using a “treasury stock” method.  Under this method, only the net number of
shares of common stock equal to the value of these junior convertible 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 our common stock) that occurs when these securities
are converted and we are relieved of our debt obligation.

interest) and Economic earnings per share:

tax windfalls and shortfalls from share-based compensation, unrealized gains and losses on seed capital, general partner

$2.8 million for the nine months ended September 30, 2023 and 2024, respectively.
Liquidity and Capital Resources
We generate long-term value by investing in new Affiliate partnerships, existing Affiliates, and strategic value-add
capabilities through which we can leverage our scale and resources to benefit our Affiliates and enhance their long-term growth
prospects.  Given our annual cash generation from operations, in addition to investing for growth in our business, we are also
able to return excess capital to shareholders primarily through share repurchases.  We continue to manage our capital structure
consistent with an investment grade company and are currently rated A3 by Moody’s Investor Services and BBB+ by S&P
Global Ratings. 
Cash and cash equivalents were $1,010.7 million as of September 30, 2024 and were attributable to both our controlling
and the non-controlling interests.  In the nine months ended September 30, 2024, we met our cash requirements primarily
through cash generated by operating activities.  Our principal uses of cash in the nine months ended September 30, 2024 were
for the return of excess capital through share repurchases, repayment of debt, purchases of investment securities, and
distributions to Affiliate equity holders.
We expect investments in new Affiliates, investments in existing Affiliates, primarily through purchases of Affiliate equity
interests and general partner and seed capital investments, the return of capital through share repurchases and the payment of
cash dividends on our common stock, repayment of debt, distributions to Affiliate equity holders, payment of income taxes,
purchases of marketable securities, and general working capital to be the primary uses of cash on a consolidated basis for the
foreseeable future.  We anticipate that our current cash balance, cash flows from operations, proceeds from sales of our
marketable securities, and borrowings under our senior unsecured multicurrency revolving credit facility (the “revolver”) will
be sufficient to support our uses of cash for the foreseeable future.  In addition, we may draw funding from the debt and equity
capital markets, and our credit ratings, among other factors, allow us to access these sources of funding on favorable terms.
The following table presents operating, investing, and financing cash flow activities:

Operating Cash Flow
Operating cash flows are calculated by adjusting Net income for other significant sources and uses of cash, significant non-
cash items, and timing differences in the cash settlement of assets and liabilities. 
For the nine months ended September 30, 2024, Cash flows from operating activities were $719.6 million, primarily from
Net income of $519.5 million and distributions of earnings received from equity method investments of $357.3 million.  These
items were partially offset by timing differences in the cash settlement of receivables, other assets, and payables, accrued
liabilities, and other liabilities of $100.0 million.  For the nine months ended September 30, 2024, operating cash flows were
primarily attributable to the controlling interest.
Investing Cash Flow
For the nine months ended September 30, 2024, Cash flows from investing activities were $370.6 million, primarily due to
$875.2 million of maturities and sales of investment securities, partially offset by $496.4 million of purchases of investment
securities.  For the nine months ended September 30, 2024, investing cash flows were primarily attributable to the controlling
interest.
Financing Cash Flow
For the nine months ended September 30, 2024, Cash flows used in financing activities were $904.1 million, primarily due
to $589.5 million of repurchases of common stock (net), repayment of senior notes and senior bank debt of $400.0 million and
$350.0 million, respectively, $206.5 million of distributions to non-controlling interests, and $54.1 million of Affiliate equity
purchases, net of issuances.  These items were partially offset by the issuance of junior subordinated notes and senior notes of
$450.0 million and $397.6 million, respectively.
Affiliate Equity
We periodically purchase Affiliate equity from and issue Affiliate equity to our consolidated Affiliate partners and other
parties under agreements that provide us with a conditional right to call and Affiliate equity holders with a conditional right to
put their Affiliate equity interests to us at certain intervals.  We have the right to settle a portion of these purchases in shares of
our common stock.  For Affiliates accounted for under the equity method, we do not typically have such put and call
arrangements.  The purchase price of these conditional purchases is generally calculated based upon a multiple of the Affiliate’s
cash flow distributions, which is intended to represent fair value.  Affiliate equity holders are also permitted to sell their equity
interests to other individuals or entities in certain cases, subject to our approval or other restrictions.
As of September 30, 2024, the current redemption value of Affiliate equity interests was $456.0 million, of which $397.1
million was presented as Redeemable non-controlling interests (including $13.3 million of consolidated Affiliate sponsored
investment products primarily attributable to third-party investors), and $58.9 million was included in Other liabilities. 
Although the timing and amounts of these purchases are difficult to predict, we paid $60.4 million for Affiliate equity purchases
and received $6.3 million for Affiliate equity issuances during the nine months ended September 30, 2024, and we expect net
purchases of approximately $60 million of Affiliate equity during the remainder of 2024.  In the event of a purchase, we
become the owner of the cash flow associated with the purchased equity.  See Notes 13 and 14 of our Consolidated Financial
Statements.
Share Repurchases
Our Board of Directors authorized share repurchase programs in October 2022, October 2023, and July 2024 to repurchase
up to 3.0 million, 3.3 million, and 5.4 million shares of our common stock, respectively, and these authorizations have no
expiry.  Purchases may be made from time to time, at management’s discretion, in the open market or in privately negotiated
transactions, including through the use of trading plans, as well as pursuant to accelerated share repurchase programs or other
share repurchase strategies that may include derivative financial instruments.  As of March 31, 2024, we had repurchased all of
the shares in the repurchase program authorized in October 2022.  During the three and nine months ended September 30, 2024,
we repurchased 0.6 million and 3.6 million shares of our common stock at an average price per share of $163.23 and $158.62,
39

respectively.  As of September 30, 2024, there were a total of 5.9 million shares available for repurchase under our share
repurchase programs.
Debt
The following table presents the carrying value of our outstanding indebtedness.  The weighted average maturity of our
outstanding debt is 21 years, with approximately 87% of debt maturing in 2030 and beyond.  Our nearest term maturity relates
to our $350.0 million senior notes due August 2025 (“the 2025 senior notes”).  See Note 7 of our Consolidated Financial

During the nine months ended September 30, 2024, we repaid the $350.0 million outstanding under the term loan.
As of September 30, 2024, we had a $1.25 billion revolver.  The revolver matures on October 25, 2027 and the term loan
terminated upon payment in full.  Subject to certain conditions, we may increase the commitments under the revolver by up to
an additional $500.0 million. 
As of September 30, 2024, we had no outstanding borrowings under the revolver, and could borrow all capacity and remain
in compliance with the revolver.
Senior Notes
In the first quarter of 2024, our $400.0 million 2024 senior notes matured and were fully repaid.

On August 20, 2024, we issued $400.0 million of 2034 senior unsecured notes with a maturity date of August 20, 2034. 
Interest is payable beginning February 20, 2025.  In addition to customary event of default provisions, the indenture governing
the 2034 senior notes limits our ability to consolidate, merge or sell all or substantially all of its assets and requires us to make
an offer to repurchase the 2034 senior notes upon certain change of control triggering events.
The senior notes may be redeemed, in whole or in part, at a make-whole redemption price (plus accrued and unpaid
interest), at any time, in the case of the 2025 senior notes, at any time prior to March 15, 2030, in the case of the 2030 senior
notes, and at any time prior to May 20, 2034, in the case of the 2034 senior notes.  In addition, the 2030 and 2034 senior notes
may be redeemed at par, in whole or in part, at any time, on or after March 15, 2030 and May 20, 2034, respectively.  We may
also repurchase senior notes in the open market or in privately negotiated transactions from time to time at management’s
discretion.

We have used a majority of the net proceeds from the 2034 senior notes for the repayment of the term loan, and in the

On March 20, 2024, we issued $450.0 million of 2064 junior subordinated notes with a maturity date of March 30, 2064. 
Interest was payable commencing on June 30, 2024, and we have the right to defer interest payments in accordance with the
terms of the notes.  The 2064 junior subordinated notes were issued at 100% of the principal amount and rank junior and
subordinate in right of payment and upon liquidation to all of our current and future senior indebtedness.  As of September 30,
2024, the 2059 junior subordinated notes could be redeemed at any time, in whole or in part.  The other junior subordinated
notes may be redeemed at any time, in whole or in part, on or after September 30, 2025, in the case of the 2060 junior
subordinated notes, on or after September 30, 2026, in the case of the 2061 junior subordinated notes, and on or after March 30,
2029, in the case of the 2064 junior subordinated notes.  In each case, the junior subordinated notes may be redeemed at 100%
of the principal amount of the notes being redeemed, plus any accrued and unpaid interest thereon.  Prior to the applicable
redemption date, at our option, the applicable junior subordinated notes may also be redeemed, in whole but not in part, at
100% of the principal amount, plus any accrued and unpaid interest, if certain changes in tax laws, regulations, or
interpretations occur; or at 102% of the principal amount, plus any accrued and unpaid interest, if a rating agency makes certain
changes relating to the equity credit criteria for securities with features similar to the applicable notes.
We have used, and in the future intend to use, the net proceeds from the 2064 junior subordinated notes for general
corporate purposes, which may include the repayment or refinancing of indebtedness, share repurchases, and investments in
new and existing Affiliates.
Junior Convertible Securities
As of September 30, 2024, we had $341.7 million of principal outstanding in our 5.15% junior convertible trust preferred
securities (the “junior convertible securities”), maturing in 2037.  The junior convertible securities were issued by AMG Capital
Trust II, a Delaware statutory trust, in October 2007.  Each of the junior convertible securities represents an undivided
beneficial interest in the assets of the trust.  The trust’s only assets are junior subordinated convertible debentures issued to it by
us, and have substantially the same payment terms as the junior convertible securities.  We own all of the trust’s common
securities, and have fully and unconditionally guaranteed, on a subordinated basis, the payment obligations on the junior
convertible securities.  We do not consolidate the trust’s financial results into our Consolidated Financial Statements.
Holders of the junior convertible securities have no rights to put these securities to us.  Upon conversion, holders will
receive cash or shares of our common stock, or a combination thereof, at our election.  We may redeem the junior convertible
securities, subject to our stock trading at or above certain specified levels over specified periods, and may also repurchase junior
convertible securities in the open market or in privately negotiated transactions from time to time at management’s discretion. 
We did not repurchase any of our junior convertible securities during the nine months ended September 30, 2023 and 2024.
Equity Distribution Program
In the second quarter of 2022, we entered into equity distribution and forward equity agreements with several major
securities firms under which we may, from time to time, issue and sell shares of our common stock (immediately or on a
forward basis) having an aggregate sales price of up to $500.0 million (the “equity distribution program”).  This equity
distribution program superseded and replaced our prior equity distribution program.  As of September 30, 2024, no sales had
occurred under the equity distribution program.

Leases
As of September 30, 2024, our lease obligations were $10.2 million for the remainder of 2024, $62.4 million from 2025
through 2026, $45.0 million from 2027 through 2028, and $70.4 million thereafter.  The portion of these lease obligations
attributable to the controlling interest were $2.8 million for the remainder of 2024, $13.9 million from 2025 through 2026, $4.1
million from 2027 through 2028, and $8.5 million thereafter.

Critical Accounting Estimates and Judgments
Our 2023 Annual Report on Form 10‑K includes additional information about our Critical Accounting Estimates and
Judgments, and should be read in conjunction with this Quarterly Report on Form 10‑Q.
Item 3.Quantitative and Qualitative Disclosures About Market Risk
There have been no material changes to our Quantitative and Qualitative Disclosures About Market Risk for the nine
months ended September 30, 2024, except as noted below.  Please refer to Item 7A of our 2023 Annual Report on Form 10-K.
Interest Rate Risk
We have fixed rates of interest on our senior notes, junior subordinated notes, and junior convertible securities.  While a
change in market interest rates would not affect the interest expense incurred on our fixed rate securities, such a change may
affect the fair value of these securities.  We estimate that a 1% change in interest rates would have resulted in a $204.7 million
net change in fair value of our fixed rate securities as of September 30, 2024.  This represents an increase of $59.0 million as
compared to the estimated impact of a 1% change in interest rates as of December 31, 2023.  This increase is primarily due to
the issuances of $450.0 million of 2064 junior subordinated notes in March 2024 and $400.0 million of 2034 senior notes in
August 2024.
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 officer concluded that our disclosure controls and procedures were
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.
