The adoption of these updates did not have a significant impact on the Company’s Consolidated Financial Statements.
In May 2014,June 2022, the Financial Accounting Standards Board (the “FASB”(“FASB”) issued ASU 2014-09, Revenue from Contracts with Customers, and subsequently issued several related amendments. The standard provides a comprehensive model for revenue recognition and is effective for the Company and its consolidated Affiliates for interim and annual periods beginning after December 15, 2017 and for interim and annual periods beginning after December 15, 2018 for the Company’s equity method Affiliates. The standard may be adopted using either the full or modified retrospective method. The Company has not yet selected its transition method and continues to evaluate the impact of this standard on its Consolidated Financial Statements, but it does not expect the adoption to significantly impact the timing of the recognition of its Revenue. The Company is evaluating whether certain costs currently expensed as incurred meet the criteria for capitalization and whether certain revenue-related costs will be presented on a gross or net basis. 
In January 2016, the FASB issued ASU 2016-01,Accounting Standards Update (“ASU”) 2022-03, Fair Value: Recognition andValue Measurement (Topic 820): Fair Value Measurement of Financial Assets and Liabilities.  UnderEquity Securities Subject to Contractual Sale Restrictions, which clarifies the new standard, all equity investmentsguidance in unconsolidated entities (other than those accounted for usingTopic 820 on the equity method of accounting) will generally be measured at fair value with any changes recognized through earnings.measurement of an equity security that is subject to a contractual sale restriction and requires specific disclosures related to such an equity security. The standard is effective for interim and annual periods beginning after December 15, 2017 and must be adopted using a modified retrospective method.  The impact of this standard on the Company’s Consolidated Financial Statements will depend on the equity investments held by2023 for the Company, at the time of adoption.
In February 2016, the FASB issued ASU 2016-02, Leases, which requires lessees to recognize assets and liabilities arising from most operating leases on the statement of financial position. The standard is effective for interim and annual periods beginning after December 15, 2018 for the Company and its consolidated Affiliates and for interim and annual periods beginning after December 15, 20192024 for the Company’s equity method Affiliates. The standard must be adopted using a modified retrospective method. The Company is evaluating the impact of this standard, however it currently does not expect the adoption to have a material impact on its Consolidated Financial Statements.

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 notes receivable, which is reported in Other assets, approximates fair value because interest rates and other terms are at market rates. 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 areand 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 entitiesentity (“VREs”VRE”) becauseor a variable interest entity (“VIE”). An entity is a VRE when the total equity investment at risk is sufficient to enable the entitiesentity to finance their respectiveits activities independently, and each entity’swhen the equity holders have the obligation to absorb losses, the right to receive residual returns, the obligation to absorb losses 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.

that most significantly impact its economic performance. MostThe Company consolidates VREs when it has control over significant operating, financial, and investing decisions of the Company’s Affiliates considered VREs are accounted for under the equity method becauseentity. When the Company lacks such control, but is deemed to have significant influence.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.

Substantially all of the Company’s Affiliates are considered variable interest entities (“VIEs”) because they are structured as partnerships (or similar entities) and the limited partners lack substantive kick-out or substantive participation rights over the general partner. The Company consolidates a VIEVIEs 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, or the obligation to absorb losses of 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 a VIE when itVIEs where the Company is not the primary beneficiary, but has the ability to exercise significant influence over operating and financial matters of the VIE.
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 deemedconsolidated, 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 presented within 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 reported in Equity method investments in Affiliates (net) in the Consolidated Balance Sheets. Deferred taxes recorded on intangible assets upon acquisition of an Affiliate accounted for under the equity method are presented on a gross basis within Equity method investments in Affiliates (net) and Deferred income tax liability (net) in the Consolidated Balance Sheets. The Company’s share of income taxes incurred directly by Affiliates accounted for under the equity method is recorded in Income tax expense in the Consolidated Statements of Income.
The Company periodically performs assessments to determine if the fair value of an investment may have significant influence.

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. Where the Company believes that such declines may have occurred, the Company determines the amount of impairment using valuation methods, such as discounted cash flow analyses. Impairments are recorded as an expense in Equity method income (net) to reduce the carrying value of the Affiliate to its fair value.
The unconsolidated assets, net of liabilities and non-controlling interests of Affiliates accounted for under the equity method Affiliates considered VIEs, and the Company’s carrying value and maximum risk ofexposure to loss, were as follows:

Affiliate Sponsored Investment Products

The Company’s consolidated Affiliates sponsor various investment products for which theywhere the Affiliate also actacts as the investment advisor.adviser. These investment products are typically owned primarily owned 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.

Certain 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 Company’sinvestment 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 other 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.

The Company's Affiliates’ involvement withCompany’s carrying value, and maximum exposure to loss from unconsolidated Affiliate sponsored investment products, is generally limited to that of a service provider, and their seed capital investments, if any, represent an insignificant interest in the relevant investment products’ net assets.

Amounts are presented within Other assets or Other liabilities.
The following are descriptions of the significant financial assets and liabilities measured at fair value and the fair value methodologies used.
Cash equivalents consist primarily of highly liquid investments in daily redeeming money market funds, without enacted liquidity fees or redemption gates that are valued at net asset value (“NAV”).
Investments in marketable securities consist primarily of investments in publicly traded securities and funds advised by Affiliates that are valued at NAV. Publicly traded securities valued using unadjusted quoted market prices for identical instruments in active markets are classified as level 1. Publicly traded securities valued using quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active are classified as level 2. Investments in funds advised by Affiliates that are valued at NAV are classified as level 1.
Contingent payment arrangements represent the present value of the expected future settlement of contingent payment arrangements related to the Company’s investments in consolidated Affiliates. The significant unobservable inputs that are used in the fair value measurement of these obligations are growth and discount rates. Increases in the growth rate result in a higher obligation while increases in the discount rate result in a lower obligation.
Affiliate equity obligations include agreements to repurchase Affiliate equity. The significant unobservable inputs that are used in the fair value measurement of the agreements to repurchase Affiliate equity are growth and discount rates. Increases in the growth rate result in a higher obligation while increases in the discount rate result in a lower obligation.
Foreign currency forward contracts use model-derived valuations in which all significant inputs are observable in active markets to determine fair value.
It is the Company’s policy to value financial assets or liabilities transferred as of the beginning of the period in which the transfer occurs. There were no significant transfers of financial assets or liabilities between level 1 and level 2 in the three and nine months ended September 30, 2016 and 2017.

The Company uses NAV as a practical expedient one quarter in arrears (adjusted for current period calls and distributions) to determine the fair value. These funds primarily invest in a broad range of private equity funds, as well as making direct investments. Distributions will be received as the underlying assets are liquidated over the life of the funds, which is generally up to 15 years.
(2)
These are multi-disciplinary funds that invest across various asset classes and strategies, including long/short equity, credit and real estate. Investments are generally redeemable on a daily, monthly or quarterly basis.

Fair value attributable to the controlling interest was $59.9 million and $72.8 million as of December 31, 2016 and September 30, 2017, respectively.
Other Financial Assets and Liabilities Not Carried at Fair Value
The carrying amount of Receivables and Payables and accrued liabilities approximates fair value because of the short-term nature of these instruments. The carrying value of notes receivable, which is reported in Other assets, approximates fair value because interest rates and other terms are at market rates. The carrying value of the credit facilities, which is reported in Senior bank debt, approximates fair value because the debt has variable interest based on selected short-term rates.

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). The current redemption value ofPrior to becoming redeemable, the Company’s Affiliate equity interests is presented aswithin Non-controlling interests. Upon becoming redeemable, these interests are reclassified to Redeemable non-controlling interests.interests at their current redemption values. Changes in the current redemption value are recorded to Additional paid-in capital.

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 recognized 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 disclosespresents the cumulative effect that ownership changes had on the controlling interest’s equity related only to Affiliate equity transactions that settledoccurred during the applicable periods:

The Company’s effective tax rate (controlling interest) for the three months ended March 31, 2022 was higher than the marginal tax rate of 24.5%, primarily due to increases in non-deductible compensation expense and unrecognized tax benefits, partially offset by tax benefits from foreign operations. The Company’s effective tax rate (controlling interest) for the three months ended March 31, 2023 was lower than the marginal tax rate of 24.5%, primarily due to tax windfalls related to share-based compensation, partially offset by the impact of the increase in the UK corporate tax rate in 2023.
In August 2022, the Inflation Reduction Act was enacted into law. The relevant provisions of the Inflation Reduction Act for the Company are the 15% corporate alternative minimum income tax and the 1% excise tax on repurchases of the Company’s common stock. These provisions are effective as of January 1, 2023. The Company does not currently expect the Inflation Reduction Act to have a material impact on its Consolidated Financial Statements. The Company expects to record the excise tax as part of the cost basis of its common stock repurchased.
16.Earnings Per Share
Taxes attributable to the controlling interest divided by Income before income taxes (controlling interest).

17.Segment Information
In the first quarter of 2017, the Company’s Chief Operating Decision Maker (the “CODM”) changed the manner in which he assesses the Company’s performance. In 2016, the CODM assessed the performance of the Company in three business segments representing three distribution channels. Given an increase in the number of the Company’s Affiliates accounted for under the equity method of accounting and changes in the way asset management services are delivered, during the first quarter of 2017, the CODM began to assess the performance of the Company as a single global active asset management company. As a result, the CODM now reviews information organized around one operating segment to evaluate and manage the Company’s business operations. Therefore, the Company has determined that it has one reportable segment. In connection with this change, the Company completed impairment assessments based on its former three distribution channels, as well as its single global active asset management reporting unit, and determined that there were no impairments under either approach.

Executive Overview
We areAMG is a global asset management company with equity investments in leading boutiquepartner to independent investment management firms which we referglobally. 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 “Affiliates.”unique opportunity set to the areas of highest growth and return. Our innovative partnership approach allowsenables each Affiliate’s management team to own significant equity in their firm while maintaining operational and maintain operationalinvestment autonomy. Our strategy is to generate shareholder value through the growth of existing Affiliates, as well as through investments in new Affiliates and additional investments in existing Affiliates. In addition, we provide centralized assistance tooffer our Affiliates ingrowth capital, distribution, and other strategic matters, marketing, distribution, product developmentvalue-added capabilities, which enhance the long-term growth of these independent businesses, and operations.enable them to align equity incentives across generations of principals to build enduring franchises. As of September 30, 2017,March 31, 2023, our aggregate assets under management were $803.7approximately $668 billion in more than 550 investment products across a broad range of active, return-orienteddifferentiated investment strategies.
We hold meaningful equity interestsOperating Performance Measures
Under accounting principles generally accepted in eachthe U.S. (“GAAP”), we are required to consolidate certain of our Affiliates. In certain cases, we consolidate the Affiliate’s financial results in our Revenue, Operating expensesAffiliates and Non-operating (income) and expenses. In other cases, we use the equity method of accounting and our share of the Affiliate’s financial results is reported (net of intangible amortization) in Income from equity method investments. While we account for a majority of our Affiliates on a consolidated basis of accounting, a growing number of our Affiliates are accounted for on an equity method basis and are integral to our operations. Accordingly, Income from equity method investments is included in Operating income.
others. Whether we account forconsolidate an Affiliate on a consolidated or use the equity method basis of accounting, we generally maintain the same innovative partnership approach and provide support and assistance in substantially the same manner andfor all of our operating model is generally the same.Affiliates. Furthermore, all of our Affiliates are investment managers and are impacted by similar marketplace factors and operational trends, which may not be observable when analyzing the financial results ofindustry trends. Therefore, our consolidated and equity method Affiliates separately. Therefore, we believe ourkey aggregate operating performance measures of assets under management, average assets under management and aggregate revenue, which incorporate the assets under management and revenues of all of our Affiliates, regardless of the accounting treatment, have become increasinglyare important in providing management and investors with a more comprehensive view of the operating performance and material trends across our entire business. Aggregate revenue is calculated by combining the Revenue of our consolidated Affiliates with equity method revenue. We discuss both Revenue at our consolidated Affiliates and equity method revenue in our Results of Operations. Equity method revenue and aggregate revenue are provided in addition to, but not as substitutes for, Revenue at our consolidated Affiliates.

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 Consolidated Financial Statements. Average assets under management provides a more meaningful relationship to our financial and operating results as it reflects both the particular billing patterns of Affiliate sponsored products and client accounts and corresponds with the timing of the inclusion of an Affiliate's financial results in our Consolidated Financial Statements.

(2)
Equity method revenue consists of asset based revenue and performance fees earned by our equity method Affiliates.
Assets Under Management
Through our Affiliates, we manage active return-oriented strategies rather than passive or indexing strategies, fixed income or money market products, which typically carry lower fee rates. We continue to see meaningful client demand for active return-oriented strategies, particularly in alternative and multi-asset strategies, reflecting continued investor demand for returns that are less correlated to traditional equity and fixed income markets.  Investor demand for passively managed and indexing strategies has continued, particularly for the large cap U.S. equity portion of client portfolios, and we have experienced outflows in U.S. equity strategies consistent with this industry-wide trend. We expect client demand for alternative and multi-asset strategies to continue, and believe the best-performing active equity managers (whether global-, regional- or country-specific) will continue to have significant opportunities to grow from net client cash inflows. We believe we are well positioned to benefit from these trends.

The following charts and tables provide information regarding the composition of and changes in our assets under management on a current basis by active return-oriented strategy and client type:

Alternatives primarily include assets under management in long and short public equity, control equity, managed futures, multi-strategy, and other alternative and hedge fund strategies, as well as energy and infrastructure investments and primary and secondary private equity strategies.  Alternative strategies generate earnings from (i) management fees from products subject to lock-ups or similar restrictions, (ii) management fees from products not subject to such restrictions and/or (iii) performance fees and carried interest.

Global equities include emerging markets strategies, which accounted for 10% of our aggregate assets under management as of September 30, 2017.

Foreign exchange reflects the impact of translating non-U.S. dollar denominated assets under management into U.S. dollars for reporting purposes.

In addition to assets under management, we also report average assets under management. Average assets under management provides a more meaningful relationship to our financial and operating results as it reflects both the particular billing patterns of Affiliate sponsored products and client accounts and corresponds with the timing of the inclusion of an Affiliate’s financial results in our operating performance measures and Consolidated Financial Statements.

Average assets under management increased $127.1 billion or 19%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 three months ended September 30, 2017 compared to the corresponding period in the prior year, due to a 32% increase indaily net assets under management, while for institutional and high net worth clients, average assets under management generally represents an average of the assets at equity method Affiliates and a 10% increase in average assets under management at consolidated Affiliates. Average assets under management increased $121.0 billionthe beginning or 19% inend of each month during the nine months ended September 30, 2017 compared to the corresponding period in the prior year, due to a 34% increase in average assets under management at equity method Affiliates and a 8% increase in average assets under management at consolidated Affiliates.

For certain of our Affiliates accounted for under the equity method, we report aggregate fees and the Affiliate’s financial results in our Consolidated Financial Statements one quarter in arrears. Aggregate fees are provided in addition to, but not as substitutesa substitute for, RevenueConsolidated 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 demand for alternative strategies, as evidenced by our net inflows in this category for the quarter ended March 31, 2023. At the same time, we experienced outflows in equity strategies particularly in global equities, in line with de-risking trends across the industry. We continue to invest in areas of long-term client demand — including private markets, liquid alternatives, sustainable strategies, wealth management, and Asia — through new and existing Affiliates, to 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.

(1)Past performance is not indicative of future results. Performance and AUM information is as of March 31, 2023 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
26

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.
(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. We derive our aggregate revenue primarily from asset based revenue and performanceAsset-based fees from investment management services. Asset based revenue includesinclude 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. Performancemanagement, generally inclusive of uncalled commitments. Asset-based fees are billedgenerally 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 uponon investment performance, typically on an absolute basis or relative to a benchmark.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 March 31, 2023, approximately 26% of our total assets under management could potentially earn performance-based fees. These percentages were approximately 12% and 47% 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 predominantly earned by our Affiliates accounted for under the equity method.

Our ratioAggregate fees were $1,505.1 million for the three months ended March 31, 2023, an increase of asset based revenue$174.6 million or 13% as compared to the three months ended March 31, 2022. The increase in our aggregate fees was principally due to a $362.5 million or 27% increase from performance-based fees, primarily in our liquid alternative strategies, offset by a $187.9 million or 14% decrease in asset-based fees. The decrease in asset-based fees was principally due to a decrease in our average assets under management, (“asset based revenue ratio”), eitherprimarily in our U.S. and global equity strategies, and the aggregate or separately for consolidated Affiliates or equity method Affiliates, is calculated as asset based revenue divided by average assets under management for the respective Affiliates. Our asset based revenue ratios may change as a result of new investments, client cash flows, market changes, foreign exchange or changes in contractual fees.

Aggregate revenue increased 27% in the three months ended September 30, 2017. This increase was due to a $230.2 million or 50% increase in equity method revenue and a $41.0 million or 8% increase in Revenue at our consolidated Affiliates. The increase in equity method revenue was due to an increase of $166.8 million or 36% from asset based revenue and an


increase of $63.4 million or 14% from performance fees. The increase in Revenue at our consolidated Affiliates was due to an increase of $38.2 million or 7% from asset based revenue and a $2.8 million or 1% increase from performance fees.

Aggregate revenue increased 29% in the nine months ended September 30, 2017, due to an increase in equity method revenue of $809.3 million or 60% and a $56.7 million or 3% increase in Revenue at our consolidated Affiliates. The increase in equity method revenue was due to an increase of $532.9 million or 40% from asset based revenue and an increase of $276.4 million or 20% from performance fees. The increase in Revenue at our consolidated Affiliates was due to a $70.1 million or 4% increase from asset based revenue, partially offset by a $13.4 million or 1% decrease from performance fees.

Adjusted EBITDA (controlling interest) and Economic net income (controlling interest) are non-GAAP performance measures and are discussed in “Supplemental Financial Performance Measures.”
We believe Adjusted EBITDA (controlling interest) is an important supplemental financial performance measure for our management and investors. Adjusted EBITDA (controlling interest)as it provides a comprehensive view of our share of the financial performance of our entire business before interest, taxes, depreciation, amortization, impairments and adjustments to our contingent payment obligations. Conversely, our GAAP financial performance measures, Operating income and Income before income taxes, include the non-controlling interest’s share of financial performance.
Our ownership level of consolidated Affiliates is higher than our ownership level of our equity method Affiliates and, as a result, we experience a greater proportion of an increasebusiness. While aggregate fees increased $174.6 million or decrease in Revenue from our consolidated Affiliates than an increase or decrease in our equity method revenue. While our equity method revenue increased 50%13% in the three months ended September 30, 2017,March 31, 2023, our Revenue from consolidated Affiliates increased 8%, resulting in a $36.5Adjusted EBITDA (controlling interest) decreased $23.2 million or 17%10%, primarily due to the recognition of performance fees at Affiliates in which we hold less of an economic interest.
For the three months ended March 31, 2023, our Net income (controlling interest) decreased $11.5 million or 8%. The decrease in Net income (controlling interest) was primarily due to an $89.9 million or 15% decrease in Consolidated revenue and an increase in Other expenses (net) attributable to the controlling interest, primarily related to the increase in the values of contingent payment and Affiliate equity purchase obligations. The impact of these items was partially offset by a $10.0 million increase in Equity method income (net) and an $8.0 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 March 31, 2023, our Economic net income (controlling interest) decreased $20.4 million or 11%, primarily due to a $23.2 million decrease in Adjusted EBITDA (controlling interest). In, partially offset by an $8.0 million decrease in Income tax expense attributable to the nine months ended September 30, 2017, our equity method revenue increased 60%, while our Revenue from consolidated Affiliates increased 3%, resulting in a $99.0 million or 15% increase in Adjusted EBITDA (controlling interest).controlling interest.
Our Net income (controlling interest) increased $15.2 million or 14% and $51.7 million or 16% in the three and nine months ended September 30, 2017, respectively, which was consistent with the 17% and 15% increases in Adjusted EBITDA (controlling interest) during the respective periods.
We consider Economic net income (controlling interest) to be an important measure of our financial performance, as we believe it best represents our performance after tax and before our share of non-cash expenses relating to our acquisition of interests in our Affiliates. Our Economic net income (controlling interest) increased $25.8 million or 16% and $70.9 million or 14% in the three and nine months ended September 30, 2017, respectively, which was consistent with the 17% and 15% increases in Adjusted EBITDA (controlling interest) during the respective periods.

The change in asset based revenue was due to an 8% increase in average assets under management and a 3% decline in our asset based revenue ratio. The decline in our asset based revenue ratio wasprincipally due to a decrease in asset based revenue related to renewal commissions at one of our Affiliates in the United Kingdom as a result of a regulatory change which was offset by a reduction in distribution expenses at theconsolidated Affiliate which were reported in Selling, general and administrative expenses. The decline in our asset based revenue ratio was also due to changes in the composition of our average assets under management.management primarily in our U.S. and global equity strategies.

Supplemental Financial Performance Measures
Adjusted EBITDA (controlling interest)
As supplemental information, we provide a non-GAAP measure that we refer to asperformance measures of Adjusted EBITDA (controlling interest)., Economic net income (controlling interest), and Economic earnings per share. Management utilizes these non-GAAP performance measures to assess our performance before our share of certain non-cash expenses and to improve comparability between periods. In the first quarter of 2023, we updated the definitions of Adjusted EBITDA (controlling interest) representsand Economic net income (controlling interest) to reflect AMG's strategic evolution, including our increased allocation of capital toward private markets and liquid alternatives. To align with the economic impact of these capital allocation decisions, the updated definitions of Adjusted EBITDA (controlling interest) and Economic net income (controlling interest): i) include only the realized economic gains and losses on seed capital, general partner commitments, and other strategic investments and ii) exclude any unrealized gains and losses on strategic investments (consistent with the existing treatment of seed capital and general partner commitments). We have retroactively applied this definition change to prior periods. The table below shows the impact on the years ended December 31, 2020, 2021, and 2022, as well as the three months ended March 31, 2022. Periods prior to 2020 were also affected by this definition change, none of which were material in any calendar year.

Adjusted EBITDA (controlling interest)
Adjusted EBITDA (controlling interest) is an important supplemental financial performance measure for management as it provides a comprehensive view of the financial performance of our business before our share of interest expense, income and certain non-income based taxes, depreciation, amortization, impairments, gains and adjustmentslosses related to the BPEA Transaction, and non-cash items such as certain Affiliate equity activity, gains and losses on our contingent payment obligations.obligations, and unrealized gains and losses on seed capital, general partner commitments, and other strategic investments. Adjusted EBITDA (controlling interest) is also adjusted for realized economic gains and losses related to these seed capital, general partner commitments, and other strategic investments. We believe that many investors use this informationnon-GAAP measure when assessing the financial performance of companies in the investment management industry. This non-GAAP performance measure is provided in addition to, but not as a substitute for, Net income (controlling interest) or any other GAAP measures of financial performance.performance measures.

Economic Net Income (controlling interest) and Economic Earnings Per Share
As supplemental information, we also provide non-GAAP measures that we refer to as Economic net income (controlling interest) and Economic earnings per share. We considerbelieve Economic net income (controlling interest) and Economic earnings per share to beare important measures of our financial performance, as we believebecause they best represent our performance before our share of non-cash expenses relating to ourthe acquisition of interests in our Affiliates and they are, therefore, employed as our principal financialimprove comparability of performance measures.between periods. Economic net income (controlling interest) and Economic earnings per share are used by our management and Board of Directors as our principal performance benchmarks, including as one of the measures for aligning executive compensation with stockholder value. These non-GAAP performance measures are provided in addition to, but not as substitutes for, other GAAP measures of financial performance, such as Net income (controlling interest) and Earnings per share (diluted). or other GAAP performance measures.
Under our Economic net income (controlling interest) definition, we add toadjust Net income (controlling interest) for our share of pre-tax intangible amortization and impairments attributable to intangible assets (including the portion attributable to equity method investments in Affiliates), deferred taxes related to intangible assets, and other economic items, which include non-cash imputed interest (principally related to the accounting for convertible securities and contingent payment arrangements) and certain Affiliate equity expenses. We add back intangible amortization and impairments attributable to acquired client relationships because these expenses do not correspond to the changes in the value of these assets, which do not diminish predictably over time. The portion ofWe also adjust for deferred taxes generally attributable to intangible assets (including goodwill) is added back because we believe it is unlikely these accruals will be used to settle material tax obligations. We add back non-cash imputed interestFurther, we adjust for gains and reductions or increases in contingent payment arrangementslosses related to better reflect our contractual interest obligations. We add back non-cash expenses relatingthe BPEA Transaction, net of tax, and other economic items to certain transfersimprove comparability of equityperformance between Affiliate partners when these transfers have no dilutive effect to shareholders.periods.
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, isare 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. This method does not take into account any increase or decrease in our cost of capital in an assumed conversion.

Liquidity and Capital Resources
DuringWe 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 $832.8 million as of March 31, 2023 and were attributable to both our controlling and the ninenon-controlling interests. In the three months ended September 30, 2017,March 31, 2023, we met our cash requirements primarily through cash generated by operating activities. Our principal uses of cash duringin the quarterthree months ended March 31, 2023 were and for the foreseeable future are expected to be, for

We expect investments in new Affiliates, investments in existing Affiliates primarily through purchases of common stock, 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, and general working capital purposes. We also expect that a principal useto be the primary uses of cash will beon a consolidated basis for investments in new and existing Affiliates.the foreseeable future. We anticipate that our current cash balance, cash flows from operations, together withproceeds from sales of our marketable securities, and borrowings under our revolver and proceeds from our equity distribution program, will be sufficient to support our cash flow needs for the foreseeable future.

Cash and cash equivalents at December 31, 2016 and September 30, 2017 were $430.8 million and $374.7 million, respectively, including $18.9 million and $24.9 million, respectively, in our wholly-owned foreign subsidiaries, which could be repatriated without accruing or paying any significant additional U.S. taxes.

Operating Cash Flow
In the nine months ended September 30, 2017, Cash flow from operating activities increased $116.0 million, of which approximately 70% was attributable to the controlling interest. Cash flow from operating activities attributable to the controlling interest increased primarily from the receipt of cash distributions of our share of equity method earnings from our 2016 investments in new Affiliates.
Investing Cash Flow
In the nine months ended September 30, 2017, Cash flows from investing activities, which is primarily attributable to the controlling interest, increased $873.6 million, primarily due to a decrease in Investments in Affiliates of $854.6 million.
Financing Cash Flow
In the nine months ended September 30, 2017, Cash flows used in financing activities, which is primarily attributable to the controlling interest, increased $908.1 million. This increase was primarily due to a change in senior debt activity from net borrowings of $230.0 million in the nine months ended September 30, 2016 to net repayments of $200.0 million in the nine months ended September 30, 2017.  This increase was also due to an increase in repurchases of common stock of $243.0 million and a decrease in cash received for the issuance of common stock of $129.5 million.

Cash flows used in financing activities were partially offset by $7.3 million of proceeds from Affiliate equity issuances, net of purchases.
We are currently rated A3 by Moody’s Investors Service and A- by S&P Global Ratings. A downgrade of our credit rating, including a downgrade to below investment grade, would not trigger a default or have any other significant impact on the terms of our existing credit facilities. A reduction in our credit rating could, however, increase our borrowing costs. Additionally, a downgrade of our credit rating below investment grade in connection with a change in control would require us to make a repurchase offer on our senior notes.
Equity Distribution Program

In 2016, we entered into equity distribution and forward equity agreements with several major securities firms under which we, from time to time, may 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”).  As of September 30, 2017, no sales have occurred under the equity distribution program.
Affiliate Equity
Many ofWe 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 thea 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, Affiliates, 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, 2017, ourMarch 31, 2023, the current redemption value of $804.6Affiliate equity interests was $594.1 million, for these interests has beenof which $533.2 million was presented as Redeemable non-controlling interests.interests (including $18.5 million of consolidated Affiliate sponsored investment products primarily attributable to third-party investors), and $60.9 million was presented as Other liabilities.

In the event of a repurchase,purchase, we become the owner of the cash flow associated with the repurchasedpurchased equity.
Commitments
We have committed to co-invest in certain investment partnerships. As of September 30, 2017, these unfunded commitments totaled $94.9 million See Notes 13 and may be called in future periods.
As of September 30, 2017, we were contingently liable, upon achievement by certain Affiliates of specified financial targets, to make payments related to our investments in Affiliates through 2019. For our consolidated Affiliates, we were contingently liable for up to $21.7 million, and expected to make payments of $8.9 million ($1.6 million in 2017). The present value of these expected payments was $8.1 million. For our equity method Affiliates, we were contingently liable for up to $170.0 million, and expected to make no payments.
Affiliate equity interests provide holders with a conditional right to put their interests to us over time. In addition, in connection with an investment in an Affiliate accounted for under the equity method, we entered into an arrangement with a minority owner of the Affiliate that gives such owner the right to sell a portion of its ownership interest in the Affiliate to us annually beginning in the fourth quarter of 2018. The purchase price of these conditional purchases will be at fair market value on the date of the transaction.

Share Repurchases
Our Board of Directors authorized share repurchase programs in May 2015October 2022 and January 2017, authorizing us2022 to repurchase up to 3.0 million and 1.92.0 million shares of our common stock, respectively, forand 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. During the three months ended March 31, 2023, we did not repurchase any shares of our common stock. As of March 31, 2023, there were a total of 4.93.9 million shares available for repurchase under our October 2022 and January 2022 share repurchase programs.
In December 2022, we entered into an accelerated share repurchase agreement to repurchase shares of our common stock in exchange for an upfront payment of $225.0 million. We received an initial share delivery of 1.1 million shares in December 2022, which represents 80% of the upfront payment based on the closing price of our common stock on the agreement date. The total number of shares to be repurchased will be based on volume-weighted average prices of our common stock during the term of the agreement less a discount and subject to adjustments pursuant to the terms and conditions of such agreement. The final settlement of this transaction is expected to be completed in the second or third quarter of 2023.
In August 2022, the Inflation Reduction Act was enacted into law and included a 1% excise tax on stock repurchases after December 31, 2022. We do not expire. Ascurrently expect the excise tax to have a material impact on our financial position or cash flows.

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. During the three months ended March 31, 2022, we repurchased a portion of our junior convertible securities for a purchase price of $16.5 million and as a result of September 30, 2017these repurchases, we reduced our Deferred income tax liability (net) by $2.7 million. We did not repurchase any of our junior convertible securities during the three months ended March 31, 2023.
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”).
