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. Certain reclassifications have been made to the prior period’s financial statements to conform to the current period’s presentation. Operating results for interim periods are not necessarily indicative of the results that may be expected for any other period or for the full year. The Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 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
Recent Accounting Developments
In June 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, which clarifies the guidance in Topic 820 on the fair value 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, 2023 for the Company, and is effective for interim and annual periods beginning after December 15, 2024 for the Company’s Affiliates. 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.

For the three months ended March 31, 2023, the Company recognized $0.1 million of net unrealized losses on our debt securities classified as trading still held as of March 31, 2023.
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 on 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 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, credit, and real estate. Investments are generally redeemable on a daily, monthly, or quarterly basis.
(3)Fair value attributable to the controlling interest was $275.1 million and $279.4 million as of December 31, 2022 and March 31, 2023, 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:

(1)Calculated by comparing the relative fair value of an obligation to its respective total.
(2)Represents growth rates of asset- and performance-based fees.
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.
Other Financial Assets and Liabilities Not Carried at Fair Value
The following table summarizes the Company’s other financial liabilities not carried at fair value:
 December 31, 2022March 31, 2023

Junior convertible securities341.7 346.9 341.7 336.6 Level 2
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 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.
11
AFFILIATED MANAGERS GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

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.
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 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 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 considered VIEs, and the Company’s carrying value and maximum exposure to loss, were as follows:

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 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. Purchases and sales of securities are presented within purchases and sales by consolidated Affiliate sponsored investment products in 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:

Junior Convertible Securities
As of March 31, 2023, 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, 2022 and March 31, 2023, the unamortized issuance costs related to the junior convertible securities were $3.1 million and $3.0 million, respectively.
The following table presents interest expense recognized in connection with the junior convertible securities:

Contractual interest expense$5.0 $4.4 
Amortization of debt issuance costs0.1 0.1 
Total$5.1 $4.5 
Effective interest rate5.24 %5.21 %
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. During the three months ended March 31, 2022, the Company repurchased a portion of its junior convertible securities for a purchase price of $16.5 million and as a result of these repurchases, the Company reduced its Deferred income tax liability (net) by $2.7 million. The Company did not repurchase any of its junior convertible securities during the three months ended March 31, 2023.
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 March 31, 2023, these unfunded commitments were $154.9 million and may be called in future periods.
As of March 31, 2023, the Company was obligated to make deferred payments and was contingently liable to make payments in connection with certain of its consolidated Affiliates as follows:

In the event certain financial targets are not met at one of the Company’s Affiliates accounted for under the equity method, the Company may receive payments of up to $12.5 million and also has the option to reduce its ownership interest and receive an incremental payment of $25.0 million.
Affiliate equity interests provide holders at consolidated Affiliates with a conditional right to put their interests to the Company over time. See Note 14.
The Company and certain of its consolidated Affiliates operate under regulatory authorities that require the maintenance of minimum financial or capital requirements. The Company’s management is not aware of any significant violations of such requirements.

The Company recorded amortization expense for these relationships of $23.3 million and $20.9 million for the three months ended March 31, 2022 and 2023, respectively. Based on relationships existing as of March 31, 2023, the Company estimates the amortization expense attributable to its Affiliates will be approximately $65 million for the remainder of 2023, approximately $50 million in each of 2024 and 2025, approximately $45 million in each of 2026 and 2027, and approximately $35 million in 2028.
The Company had liabilities for deferred and contingent payment obligations related to certain of its investments in Affiliates accounted for under the equity method. See Note 8.
The Company had 20 and 21 Affiliates accounted for under the equity method as of December 31, 2022 and March 31, 2023. 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 presented within Other liabilities and were $21.0 million and $19.7 million as of December 31, 2022 and March 31, 2023, 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 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, 10, 13, and 14.

These restricted stock units were valued based on the closing price of the Company’s common stock on the grant date and the number of shares expected to vest. Restricted stock units containing vesting conditions generally require service over a period of three years to four years and may also require the satisfaction of certain performance conditions. For awards with performance conditions, the number of restricted stock units expected to vest may change over time depending upon the performance level achieved.

For awards with performance conditions, the number of stock options expected to vest may change over time depending upon the performance level achieved.
For the three months ended March 31, 2022, the weighted average fair value of options granted was $47.84. The Company uses the Black-Scholes option pricing model to determine the fair value of options. The weighted average grant date assumptions used to estimate the fair value of stock options granted were as follows:

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 presented within 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 interest 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:
Redeemable Non-controlling Interests

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 $122.5 million and $79.5 million for the three months ended March 31, 2022 and 2023, 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 three months ended March 31, 2022 and 2023,
19
AFFILIATED MANAGERS GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

the amount of cash paid for purchases was $5.3 million and $5.0 million, respectively. For the three months ended March 31, 2022 and 2023, the total amount of cash received for issuances was $11.6 million and $12.3 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 total receivable was $11.6 million and $11.0 million as of December 31, 2022 and March 31, 2023, respectively, and was included in Other assets. The total payable was $24.5 million and $60.9 million as of December 31, 2022 and March 31, 2023, 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 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 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)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 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
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 share available to common stockholders:

Executive Overview
AMG is a leading partner to independent investment management 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. Our innovative partnership approach enables each Affiliate’s management team to own significant equity in their firm while maintaining operational and investment autonomy. In addition, we offer our Affiliates growth capital, distribution, and other strategic value-added capabilities, which enhance the long-term growth of these independent businesses, and enable them to align equity incentives across generations of principals to build enduring franchises. As of March 31, 2023, our aggregate assets under management were approximately $668 billion across a broad range of differentiated investment strategies.
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 more comprehensive view of the operating performance and material trends across our entire business.
The following table presents our key aggregate operating performance measures:
As of and for the Three Months Ended March 31,
(in billions, except as noted)20222023% Change
Assets under management$776.7 $668.0 (14)%
Average assets under management787.3 660.4 (16)%
Aggregate fees (in millions)1,330.5 1,505.1 13 %
24
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 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 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 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. 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 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.
Aggregate fees were $1,505.1 million for the three months ended March 31, 2023, an increase of $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, primarily in our U.S. and global equity strategies, and the impact of the BPEA Transaction (as defined in “Supplemental Financial Performance Measures”).
Financial and Supplemental Financial Performance Measures
The following table presents our key financial and supplemental financial performance measures:
For the Three Months Ended March 31, 
(in millions)20222023% Change
Net income (controlling interest)$146.0 $134.5 (8)%
Adjusted EBITDA (controlling interest)(1)
240.0 216.8 (10)%
Economic net income (controlling interest)(1)
178.5 158.1 (11)%
__________________________
27
(1)Adjusted EBITDA (controlling interest) and Economic net income (controlling interest) are non-GAAP performance measures and are discussed in “Supplemental Financial Performance Measures.”
Adjusted EBITDA (controlling interest) is an important supplemental financial performance measure for management as it provides a comprehensive view of our share of the financial performance of our business. While aggregate fees increased $174.6 million or 13% in the three months ended March 31, 2023, our Adjusted EBITDA (controlling interest) decreased $23.2 million or 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), partially offset by an $8.0 million decrease in Income tax 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 equity method Affiliates. Our consolidated Affiliates’ financial results are included in our Consolidated revenue, Consolidated expenses, and Investment and other income, and our share of our equity method Affiliates’ financial results is reported, net of intangible amortization and impairments, in Equity method income (net).
Consolidated Revenue
The following table presents our consolidated Affiliate average assets under management and Consolidated revenue:

Consolidated Affiliate average assets under management (in billions)$474.2 $399.0 (16)%
Consolidated revenue$607.3 $517.4 (15)%
Our Consolidated revenue decreased $89.9 million or 15% for the three months ended March 31, 2023, primarily due to a $90.7 million or 15% decrease in asset-based fees.  The decrease in asset-based fees was principally due to a decrease in consolidated Affiliate average assets under management primarily in our U.S. and global equity strategies.
Consolidated Expenses
Our Consolidated expenses are primarily attributable to the non-controlling interests of our consolidated Affiliates.
The following table presents our Consolidated expenses:

(1)Percentage change is not meaningful.
Compensation and related expenses decreased $32.7 million or 13% for the three months ended March 31, 2023, primarily due to a $27.1 million decrease in compensation correlated to the decrease in Consolidated revenue and a $5.6 million decrease in Affiliate equity compensation expense.
Selling, general and administrative expenses increased $7.7 million or 9% for the three months ended March 31, 2023, primarily due to a $7.0 million increase in professional fees.
There were no significant changes in Intangible amortization and impairments for the three months ended March 31, 2023.
Interest expense increased $1.4 million or 5% for the three months ended March 31, 2023, primarily due to a $3.9 million increase resulting from higher interest rates on our senior unsecured term loan facility (the “term loan”). This increase was partially offset by a $2.6 million decrease resulting from repurchases of our junior convertible securities in the first quarter of 2022.
There were no significant changes in Depreciation and other amortization for the three months ended March 31, 2023.
Other expenses (net) increased $8.8 million for the three months ended March 31, 2023, primarily due to an $11.0 million increase in expenses related to the increase in the values of contingent payment obligations and Affiliate equity purchase 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 accounted for under the equity method, net of amortization and impairments, is included in Equity method income (net).
The following table presents equity method Affiliate average assets under management and equity method revenue, as well as equity method earnings, equity method intangible amortization, and equity method intangible impairments, if any, which in aggregate form Equity method income (net):

Equity method income (net)$48.6 $58.6 21 %
Our equity method revenue increased $264.5 million or 37% for the three months ended March 31, 2023, principally due to a $361.7 million or 50% increase in performance-based fees, primarily in our liquid alternative strategies, offset by a $97.2 million or 13% decrease in asset-based fees. The decrease in asset-based fees was primarily due to the impact of the BPEA Transaction.
For the three months ended March 31, 2023, equity method earnings increased $7.6 million or 11%, primarily due to a $264.5 million or 37% increase in equity method revenue. Equity method earnings increased less than equity method revenue on a percentage basis, primarily due to the increase in performance-based fees at Affiliates in which we hold less of an economic interest.
Equity method intangible amortization decreased $2.4 million or 10% for the three months ended March 31, 2023, primarily due to a $2.7 million decrease in amortization expense related to certain definite-lived assets being fully amortized and a $1.3 million decrease due to a decline in actual and expected client attrition for certain definite-lived acquired client relationships. These decreases were partially offset by a $1.6 million increase in amortization expense due to an investment in a new Affiliate.

Income tax expense $55.7 $45.0 (19)%
Income tax expense decreased $10.7 million or 19% for the three months ended March 31, 2023, primarily due to a $4.7 million decrease in taxes resulting from the $19.5 million decrease in income before income taxes attributable to the controlling interest, a $2.7 million increase in tax windfalls related to share-based compensation, and a $2.7 million decrease in income tax attributable to the non-controlling interest.
Net Income
The following table presents Net income, Net income (non-controlling interests), and Net income (controlling interest):

Net income (non-controlling interests)72.7 54.0 (26)%
Net income (controlling interest)146.0 134.5 (8)%
Net income (controlling interest) decreased $11.5 million or 8% for the three months ended March 31, 2023, primarily due to a decrease in Consolidated revenue and an increase in Other expenses (net) attributable to the controlling interest. These changes were partially offset by an increase in Equity method income (net) and a 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. 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) and 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) 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 losses related to the BPEA Transaction, 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 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 non-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 other GAAP performance measures.
The following table presents a reconciliation of Net income (controlling interest) to Adjusted EBITDA (controlling interest):

(1)Intangible amortization and impairments in our Consolidated Statements of Income include amortization attributable to the non-controlling interests of our consolidated Affiliates. For our Affiliates accounted for under the equity method, we do not separately report intangible amortization and impairments in our Consolidated Statements of Income. Our share of these Affiliates’ amortization and impairments is reported in Equity method income (net). The following table presents the Intangible amortization and impairments shown above:
 For the Three Months Ended March 31,
(in millions)20222023
Consolidated intangible amortization and impairments$12.6 $12.5 
Consolidated intangible amortization and impairments (non-controlling interests)(4.0)(4.0)
Equity method intangible amortization and impairments23.3 20.9 
Total $31.9 $29.4 
(2)Includes gains on ordinary shares of EQT AB (“EQT”), a public company listed on Nasdaq Stockholm (EQT.ST). 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 (the “BPEA Transaction”).
(3)Other items include certain non-income based taxes, depreciation, and non-cash items such as gains and losses on our contingent payment obligations, certain Affiliate equity activity, 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
We believe Economic net income (controlling interest) and Economic earnings per share are important measures because they represent our performance before non-cash expenses relating to the acquisition of interests in Affiliates and improve comparability of performance 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, Net income (controlling interest) and Earnings per share (diluted) or other GAAP performance measures.
Under our Economic net income (controlling interest) definition, we adjust 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) 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 the BPEA Transaction, net of tax, and other economic items to improve comparability of performance between 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, 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. This method does not take into account any increase or decrease in our cost of capital in an assumed conversion.

(3)Other economic items include gains and losses related to contingent payment obligations, tax windfalls and shortfalls from share-based compensation, certain Affiliate equity activity, 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. For the three months ended March 31, 2022 and 2023, other economic items were net of income tax benefit of $1.6 million and income tax expense of $1.8 million, 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 $832.8 million as of March 31, 2023 and were attributable to both our controlling and the non-controlling interests. In the three months ended March 31, 2023, we met our cash requirements primarily through cash generated by operating activities. Our principal uses of cash in the three months ended March 31, 2023 were for 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, 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:
For the Three Months Ended March 31,
(in millions)20222023
Operating cash flow$145.0 $234.8 
Investing cash flow(157.4)288.0 
Financing cash flow(388.9)(116.9)

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 three months ended March 31, 2023, Cash flows from operating activities were $234.8 million, primarily from Net income of $188.5 million adjusted for distributions of earnings received from equity method investments of $305.5 million and for non-cash items of $30.7 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 $231.1 million. For the three months ended March 31, 2023, operating cash flows were primarily attributable to the controlling interest.
Investing Cash Flow
For the three months ended March 31, 2023, Cash flows from investing activities were $288.0 million, primarily due to net sales and maturities of investment securities. For the three months ended March 31, 2023, investing cash flows were primarily attributable to the controlling interest.
Financing Cash Flow
For the three months ended March 31, 2023, Cash flows used in financing activities were $116.9 million, primarily due to $79.5 million of distributions to non-controlling interests and $41.6 million of other financing items. Cash flows used in financing activities were partially offset by $7.3 million of proceeds from Affiliate equity issuances, net of purchases.
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 March 31, 2023, the current redemption value of Affiliate equity interests was $594.1 million, of which $533.2 million was presented as Redeemable non-controlling 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. Although the timing and amounts of these purchases are difficult to predict, we received $12.3 million for Affiliate equity issuances and paid $5.0 million for Affiliate equity purchases during the three months ended March 31, 2023, and we expect net purchases of approximately $120 million of Affiliate equity during the remainder of 2023. 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 and January 2022 to repurchase up to 3.0 million and 2.0 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. 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 3.9 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 currently expect the excise tax to have a material impact on our financial position or cash flows.

The carrying value of our debt differs from the amount reported in the notes to our Consolidated Financial Statements, as the carrying value of our debt in the table above is not reduced for debt issuance costs.
Senior Bank Debt
We have a $1.25 billion revolver and a $350.0 million term loan (together, the “credit facilities”). The revolver matures on October 25, 2027 and the term loan matures on October 23, 2026. Subject to certain conditions, we may increase the commitments under the revolver by up to an additional $500.0 million and may borrow up to an additional $75.0 million under the term loan.
As of March 31, 2023, we had no outstanding borrowings under the revolver, and could borrow all capacity and remain in compliance with our credit facilities.

Junior Convertible Securities
As of March 31, 2023, 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
35
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 these 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”). This equity distribution program superseded and replaced our prior equity distribution program. As of March 31, 2023, no sales had occurred under the equity distribution program.
Commitments
See Note 8 of our Consolidated Financial Statements.
Other Contingent Commitments
See Notes 5 and 8 of our Consolidated Financial Statements.
Leases
As of March 31, 2023, our lease obligations were $30.8 million for the remainder of 2023, $73.3 million from 2024 through 2025, $45.1 million from 2026 through 2027, and $87.5 million thereafter. The portion of these lease obligations attributable to the controlling interest were $8.4 million for the remainder of 2023, $20.2 million from 2024 through 2025, $6.4 million from 2026 through 2027, and $9.9 million thereafter.

There have been no material changes to our Quantitative and Qualitative Disclosures About Market Risk for the three months ended March 31, 2023. Please refer to Item 7A of our 2022 Annual Report on Form 10-K.
Item 4.Controls and Procedures
We carried out an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures during the quarter covered by this Quarterly Report on Form 10-Q. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the quarter covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures are effective in ensuring that (i) the information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and (ii) such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, we recognize that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and our
36
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.
