Basis of Presentation

The interim condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the interim results, have been made. The preparation of the condensed consolidated financial statements requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the interim reporting periods. Actual results could differ from those estimates. The condensed consolidated statement of financial condition as of December 31, 2020 was derived from audited financial statements. Certain disclosures included in the annual financial statements have been condensed or omitted from these financial statements as they are not required for interim financial statements under principles generally accepted in the United States of America ("GAAP") and the rules of the Securities and Exchange Commission.

Principles of Consolidation

The condensed consolidated financial statements include AB and its majority-owned and/or controlled subsidiaries, and the consolidated entities that are considered to be variable interest entities (“VIEs”) and voting interest entities (“VOEs”) in which AB has a controlling financial interest. Non-controlling interests on the condensed consolidated statements of financial condition include the portion of consolidated company-sponsored investment funds in which we do not have direct equity ownership. All significant inter-company transactions and balances among the consolidated entities have been eliminated.

Reclassifications

During 2021, prior period amounts previously presented as net issuance (repayment) of commercial paper, proceeds (repayment) of EQH facility and proceeds (repayment) of bank loans are now combined and presented as net repayments (borrowings) of debt in the condensed consolidated statements of cash flows to conform to the current period's presentation.

Subsequent Events
We have evaluated subsequent events through the date that these financial statements were filed with the Securities and Exchange Commission. See Note 18 Subsequent Events for further discussion.

2.     Significant Accounting Policies

Recently Adopted Accounting Pronouncements

In August 2018, the FASB issued ASU 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Topic 715-20). The amendment modifies the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans. We adopted this standard prospectively on January 1, 2021. The adoption of this standard did not have a material impact on our financial condition or results of operations.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify US GAAP for other areas of Topic 740 by clarifying and amending the existing guidance. We adopted this standard prospectively on January 1, 2021. The adoption of this standard did not have a material impact on our financial condition or results of operations.

4.    Long-term Incentive Compensation Plans

We maintain several unfunded, non-qualified long-term incentive compensation plans, under which we grant annual awards to employees, generally in the fourth quarter, and to members of the Board of Directors of the General Partner, who are not employed by our company or by any of our affiliates (“Eligible Directors”).

We fund our restricted AB Holding Unit awards either by purchasing AB Holding Units on the open market or purchasing newly-issued AB Holding Units from AB Holding, and then keeping these AB Holding Units in a consolidated rabbi trust until delivering them or retiring them. In accordance with the Amended and Restated Agreement of Limited Partnership of AB (“AB Partnership Agreement”), when AB purchases newly-issued AB Holding Units from AB Holding, AB Holding is
10

Index
required to use the proceeds it receives from AB to purchase the equivalent number of newly-issued AB Units, thus increasing its percentage ownership interest in AB. AB Holding Units held in the consolidated rabbi trust are corporate assets in the name of the trust and are available to the general creditors of AB.

Repurchases of AB Holding Units for the three and nine months ended March 31,September 30, 2021 and 2020 consisted of the following:

(2) The remainder related to purchases of AB Holding Units from employees to fulfill statutory tax withholding requirements at the time of delivery of long-term incentive compensation award.
Purchases of AB Holding Units reflected on the condensed consolidated statements of cash flows are net of AB Holding Unit purchases by employees as part of a distribution reinvestment election.

Each quarter, we consider whether to implement a plan to repurchase AB Holding Units pursuant to Rules 10b5-1 and 10b-18 under the Securities Exchange Act of 1934, as amended ("Exchange Act"). A plan of this type allows a company to repurchase its shares at times when it otherwise might be prevented from doing so because of self-imposed trading blackout periods or because it possesses material non-public information. Each broker we select has the authority under the terms and limitations specified in the plan to repurchase AB Holding Units on our behalf. Repurchases are subject to regulations promulgated by the SEC as well as certain price, market volume and timing constraints specified in the plan. The plan adopted during the firstthird quarter of 2021 expired at the close of business on April 28,October 27, 2021. We may adopt additional plans in the future to engage in open-market purchases of AB Holding Units to help fund anticipated obligations under our incentive compensation award program and for other corporate purposes.

During the first threenine months of 2021 and 2020, we awarded to employees and Eligible Directors 3.43.6 million and 0.10.5 million restricted AB Holding Unit awards, respectively. We used AB Holding Units repurchased during the applicable period and newly-issued AB Holding Units to fund these awards.

During the first threenine months of 2021 and 2020, AB Holding issued 0.1 million and 5,182 AB Holding Units, respectively, upon exercise of options to buy AB Holding Units. AB Holding used the proceeds of $1.9$3.4 million and $0.1 million, respectively, received from award recipients as payment in cash for the exercise price to purchase the equivalent number of newly-issued AB Units.

5.     Net Income per Unit

Basic net income per unit is derived by reducing net income for the 1% general partnership interest and dividing the remaining 99% by the basic weighted average number of limited partnership units outstanding for each period. Diluted net income per unit is derived by reducing net income for the 1% general partnership interest and dividing the remaining 99% by the total of the diluted weighted average number of limited partnership units outstanding for each period.

6. Cash Distributions

AB is required to distribute all of its Available Cash Flow, as defined in the AB Partnership Agreement, to its Unitholders and to the General Partner. Available Cash Flow can be summarized as the cash flow received by AB from operations minus such amounts as the General Partner determines, in its sole discretion, should be retained by AB for use in its business, or plus such amounts as the General Partner determines, in its sole discretion, should be released from previously retained cash flow.

Typically, Available Cash Flow has been the adjusted diluted net income per unit for the quarter multiplied by the number of general and limited partnership interests at the end of the quarter. In future periods, management anticipates that Available Cash Flow will be based on adjusted diluted net income per unit, unless management determines, with the concurrence of the Board of Directors, that one or more adjustments that are made for adjusted net income should not be made with respect to the Available Cash Flow calculation.

On April 29,October 28, 2021, the General Partner declared a distribution of $0.88$0.96 per AB Unit, representing a distribution of Available Cash Flow for the three months ended March 31,September 30, 2021. The General Partner, as a result of its 1% general partnership interest, is entitled to receive 1% of each distribution. The distribution is payable on May 27,November 24, 2021 to holders of record on May 10,November 8, 2021.

7.     Cash and Securities Segregated Under Federal Regulations and Other Requirements

As of March 31,September 30, 2021 and December 31, 2020, $1.4$0.9 billion and $1.8 billion, respectively, of U.S. Treasury Bills were segregated in a special reserve bank custody account for the exclusive benefit of our brokerage customers under Rule 15c3-3 of the Exchange Act.

Total investments related to long-term incentive compensation obligations of $58.7$62.2 million and $60.1 million as of March 31,September 30, 2021 and December 31, 2020, respectively, consist of company-sponsored mutual funds and hedge funds. For long-term incentive compensation awards granted before 2009, we typically made investments in company-sponsored mutual funds and hedge funds that were notionally elected by plan participants and maintained them (and continue to maintain them) in a consolidated rabbi trust or separate custodial account. The rabbi trust and custodial account enable us
12

Index
to hold such investments separate from our other assets for the purpose of settling our obligations to participants. The investments held in the rabbi trust and custodial account remain available to the general creditors of AB.

The underlying investments of hedge funds in which we invest include long and short positions in equity securities, fixed income securities (including various agency and non-agency asset-based securities), currencies, commodities and derivatives (including various swaps and forward contracts). These investments are valued at quoted market prices or, where quoted market prices are not available, are fair valued based on the pricing policies and procedures of the underlying funds.

We allocate seed capital to our investment teams to help develop new products and services for our clients. A portion of our seed capital trading investments are equity and fixed income products, primarily in the form of separately-managed account portfolios, U.S. mutual funds, Luxembourg funds, Japanese investment trust management funds or Delaware business trusts. We also may allocate seed capital to investments in private equity funds. In regard toRegarding our seed capital investments, the amounts above reflect those funds in which we are not the primary beneficiary of a VIE or hold a controlling financial interest in a VOE. See Note 14, Consolidated Company-Sponsored Investment Funds, for a description of the seed capital investments that we consolidate. As of March 31,September 30, 2021 and December 31, 2020, our total seed capital investments were $327.1$291.0 million and $310.3 million, respectively. Seed capital investments in unconsolidated company-sponsored investment funds are valued using published net asset values or non-published net asset values if they are not listed on an active exchange but have net asset values that are comparable to funds with published net asset values and have no redemption restrictions.

In addition, we also have long positions in corporate equities and long exchange-traded options traded through our options desk.

9.     Derivative Instruments

See Note 14, Consolidated Company-Sponsored Investment Funds, for disclosure of derivative instruments held by our consolidated company-sponsored investment funds.

We enter into various futures, forwards, options and swaps to economically hedge certain seed capital investments.  Also, we have currency forwards that help us to economically hedge certain balance sheet exposures. In addition, our options desk trades long and short exchange-traded equity options. We do not hold any derivatives designated in a formal hedge relationship under ASC 815-10, Derivatives and Hedging.

We may be exposed to credit-related losses in the event of non-performance by counterparties to derivative financial instruments. We minimize our counterparty exposure through a credit review and approval process. In addition, we have executed various collateral arrangements with counterparties to the over-the-counter derivative transactions that require both pledging and accepting collateral in the form of cash. As of March 31,September 30, 2021 and December 31, 2020, we held $3.9$2.7 million and $0.4 million, respectively, of cash collateral payable to trade counterparties. This obligation to return cash is reported in payables to brokers and dealers in our condensed consolidated statements of financial condition.

Although notional amount typically is utilized as the most commonly used measure of volume in the derivatives market, it is not used as a measure of credit risk. Generally, the current credit exposure of our derivative contracts is limited to the net positive estimated fair value of derivative contracts at the reporting date after taking into consideration the existence of netting

agreements and any collateral received. A derivative with positive value (a derivative asset) indicates existence of credit risk because the counterparty would owe us if the contract were closed. Alternatively, a derivative contract with negative value (a derivative liability) indicates we would owe money to the counterparty if the contract were closed. Generally, if there is more than one derivative transaction with a single counterparty, a master netting arrangement exists with respect to derivative transactions with that counterparty to provide for aggregate net settlement.

Certain of our standardized contracts for over-the-counter derivative transactions (“ISDA Master Agreements”) contain credit risk related contingent provisions pertaining to each counterparty’s credit rating. In some ISDA Master Agreements, if the counterparty’s credit rating, or in some agreements, our assets under management (“AUM”), falls below a specified threshold, either a default or a termination event permitting us or the counterparty to terminate the ISDA Master Agreement would be triggered. In all agreements that provide for collateralization, various levels of collateralization of net liability positions are applicable, depending on the credit rating of the counterparty. As of March 31,September 30, 2021 and December 31, 2020, we delivered $3.3$3.4 million and $6.4 million, respectively, of cash collateral into brokerage accounts. We report this cash collateral in cash and cash equivalents in our condensed consolidated statements of financial condition.

As of March 31,September 30, 2021 and December 31, 2020, we held $4.2$1.6 million and $7.5 million, respectively, of long exchange-traded equity options, which are included in other investments on our condensed consolidated statements of financial condition. In addition, as of March 31,September 30, 2021 and December 31, 2020, we held $1.3$0.7 million and $12.5 million, respectively, of short exchange-traded equity options, which are included in securities sold not yet purchased on our condensed consolidated statements of financial condition. Our options desk provides our clients with equity derivative strategies and execution for exchange-traded options on single stocks, exchange-traded funds and indices. While predominately agency-based, the options desk may commit capital to facilitate a client’s transaction. Our options desk hedges the risks associated with this activity by taking offsetting positions in equities. For the three and nine months ended March 31,September 30, 2021, and 2020, we recognized losses of $0.5 million and gains of $4.8 million and $18.4$2.6 million, respectively, on equity options activity. For the three and nine months ended September 30, 2020, we recognized losses of $4.4 million and $4.5 million, respectively, on equity option activity. These gains and losses are recognized in investment gains (losses) in the condensed consolidated statements of income.

11.     Fair Value

See Note 14, Consolidated Company-Sponsored Investment Funds, for disclosure of fair value of our consolidated company-sponsored investment funds.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the “exit price”) in an orderly transaction between market participants at the measurement date. The three broad levels of fair value hierarchy are as follows:

•    Level 1 – Quoted prices in active markets are available for identical assets or liabilities as of the reported date.

•    Level 2 – Quoted prices in markets that are not active or other pricing inputs that are either directly or indirectly observable as of the reported date.

•    Level 3 –  Prices or valuation techniques that are both significant to the fair value measurement and unobservable as of the reported date. These financial instruments do not have two-way markets and are measured using management’s best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation.

We provide below a description of the fair value methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy:

•    Money markets: We invest excess cash in various money market funds that are valued based on quoted prices in active markets; these are included in Level 1 of the valuation hierarchy.

•    Treasury Bills: We hold U.S. Treasury Bills, which are primarily segregated in a special reserve bank custody account as required by Rule 15c3-3 of the Exchange Act. These securities are valued based on quoted yields in secondary markets and are included in Level 2 of the valuation hierarchy.

•    Equity securities: Our equity securities consist principally of company-sponsored mutual funds with NAVs and various separately-managed portfolios consisting primarily of equity and fixed income mutual funds with quoted prices in active markets, which are included in Level 1 of the valuation hierarchy. In addition, some securities are valued based on observable inputs from recognized pricing vendors, which are included in Level 2 of the valuation hierarchy.

•    Derivatives: We hold exchange-traded futures with counterparties that are included in Level 1 of the valuation hierarchy. In addition, we also hold currency forward contracts, interest rate swaps, credit default swaps, option swaps

and total return swaps with counterparties that are valued based on observable inputs from recognized pricing vendors, which are included in Level 2 of the valuation hierarchy.

•    Options: We hold long exchange-traded options that are included in Level 1 of the valuation hierarchy.

•    Securities sold not yet purchased: Securities sold not yet purchased, primarily reflecting short positions in equities and exchange-traded options, are included in Level 1 of the valuation hierarchy.

•    Contingent payment arrangements: Contingent payment arrangements relate to contingent payment liabilities associated with various acquisitions. At each reporting date, we estimate the fair values of the contingent consideration expected to be paid based upon probability-weighted AUM and revenue projections, using unobservable market data inputs, which are included in Level 3 of the valuation hierarchy.

12.     Commitments and Contingencies

Legal Proceedings

With respect to all significant litigation matters, we consider the likelihood of a negative outcome. If we determine the likelihood of a negative outcome is probable and the amount of the loss can be reasonably estimated, we record an estimated loss for the expected outcome of the litigation. If the likelihood of a negative outcome is reasonably possible and we can determine an estimate of the possible loss or range of loss in excess of amounts already accrued, if any, we disclose that fact together with the estimate of the possible loss or range of loss. However, it is often difficult to predict the outcome or estimate a possible loss or range of loss because litigation is subject to inherent uncertainties, particularly when plaintiffs allege substantial or indeterminate damages. Such is also the case when the litigation is in its early stages or when the litigation is highly complex or broad in scope. In these cases, we disclose that we are unable to predict the outcome or estimate a possible loss or range of loss.

AB may be involved in various matters, including regulatory inquiries, administrative proceedings and litigation, some of which may allege significant damages. It is reasonably possible that we could incur losses pertaining to these matters, but we cannot currently estimate any such losses.

Management, after consultation with legal counsel, currently believes that the outcome of any individual matter that is pending or threatened, or all of them combined, will not have a material adverse effect on our results of operations, financial condition or liquidity. However, any inquiry, proceeding or litigation has an element of uncertainty; management cannot determine whether further developments relating to any individual matter that is pending or threatened, or all of them combined, will have a material adverse effect on our results of operation, financial condition or liquidity in any future reporting period.
13.     Leases

We lease office space, furniture and office equipment under various operating and financing leases. Our current leases have remaining lease terms of one year to 15 years, some of which include options to extend the leases for up to five years, and some of which include options to terminate the leases within one year. Since 2010, we have sub-leased over 1000000 square feet of office space.
Leases included in the condensed consolidated statement of financial condition as of March 31,September 30, 2021 and December 31, 2020 were as follows:

14. Consolidated Company-Sponsored Investment Funds

We regularly provide seed capital to new company-sponsored investment funds. As such, we may consolidate or de-consolidate a variety of company-sponsored investment funds each quarter. Due to the similarity of risks related to our involvement with each company-sponsored investment fund, disclosures required under the VIE model are aggregated, such as disclosures regarding the carrying amount and classification of assets.
We are not required to provide financial support to company-sponsored investment funds, and only the assets of such funds are available to settle each fund's own liabilities. Our exposure to loss regarding consolidated company-sponsored investment funds is limited to our investment in, and our management fee earned from, such funds. Equity and debt holders of such funds have no recourse to AB’s assets or to the general credit of AB.

The Credit Facility provides for possible increases in the principal amount by up to an aggregate incremental amount of $200.0 million; any such increase is subject to the consent of the affected lenders. The Credit Facility is available for AB and Sanford C. Bernstein & Co., LLC ("SCB LLC") business purposes, including the support of AB’s commercial paper program. Both AB and SCB LLC can draw directly under the Credit Facility, and management may draw on the Credit Facility from time to time. AB has agreed to guarantee the obligations of SCB LLC under the Credit Facility.

The Credit Facility contains affirmative, negative and financial covenants, which are customary for facilities of this type, including restrictions on dispositions of assets, restrictions on liens, a minimum interest coverage ratio and a maximum leverage ratio. As of March 31,September 30, 2021, we were in compliance with these covenants. The Credit Facility also includes customary events of default (with customary grace periods, as applicable), including provisions under which, upon the occurrence of an event of default, all outstanding loans may be accelerated and/or lender’s commitments may be terminated. Also, under such provisions, upon the occurrence of certain insolvency- or bankruptcy-related events of

Amounts under the Credit Facility may be borrowed, repaid and re-borrowed by us from time to time until the maturity of the facility. Voluntary prepayments and commitment reductions requested by us are permitted at any time without a fee (other than customary breakage costs relating to the prepayment of any drawn loans) upon proper notice and subject to a minimum dollar requirement. Borrowings under the Credit Facility bear interest at a rate per annum, which will be, at our option, a rate equal to an applicable margin, which is subject to adjustment based on the credit ratings of AB, plus one of the following indices: London Interbank Offered Rate; a floating base rate; or the Federal Funds rate.

As of March 31,September 30, 2021 and December 31, 2020, we had 0no amounts outstanding under the Credit Facility. DuringFurthermore, during the first threenine months of 2021 and the full year 2020, we did not draw upon the Credit Facility.

AB also has a $900.0 million committed, unsecured senior credit facility (“EQH Facility”) with EQH. The EQH Facility matures on November 4, 2024 and is available for AB's general business purposes. Borrowings under the EQH Facility generally bear interest at a rate per annum based on prevailing overnight commercial paper rates.

The EQH Facility contains affirmative, negative and financial covenants which are substantially similar to those in AB’s committed bank facilities. The EQH Facility also includes customary events of default substantially similar to those in AB’s committed bank facilities, including provisions under which, upon the occurrence of an event of default, all outstanding loans may be accelerated and/or the lender’s commitment may be terminated.

Amounts under the EQH Facility may be borrowed, repaid and re-borrowed by us from time to time until the maturity of the facility. AB or EQH may reduce or terminate the commitment at any time without penalty upon proper notice. EQH also may terminate the facility immediately upon a change of control of our general partner.

As of March 31,September 30, 2021 and December 31, 2020, AB had $625.0$390.0 million and $675.0 million outstanding under the EQH Facility, in each case with an interest rate of approximately 0.2%. Average daily borrowings on the EQH Facility for the first threenine months of 2021 and the full year 2020 were $622.3$434.0 million and $470.8 million, respectively, with weighted average interest rates of approximately 0.2% and 0.5%, respectively.

In addition to the EQH Facility, on September 1, 2020, AB established a new $300.0 million uncommitted, unsecured senior credit facility (“EQH Uncommitted Facility”) with EQH. The EQH Uncommitted Facility matures on September 1, 2024 and is available for AB's general business purposes. Borrowings under the EQH Unsecured Facility generally bear interest at a rate per annum based on prevailing overnight commercial paper rates. The EQH Uncommitted Facility contains affirmative, negative and financial covenants which are substantially similar to those in the EQH Facility. As of March 31,September 30, 2021 and December 31, 2020, we had 0no amounts outstanding onunder the EQH Uncommitted Facility. DuringFurthermore, during the first threenine months of 2021 and the full year 2020, we did not draw upon the EQH Uncommitted Facility.

As of March 31,September 30, 2021 and December 31, 2020, we had 0no commercial paper outstanding. The commercial paper is short term in nature, and as such, recorded value is estimated to approximate fair value (and considered a Level 2 security in the fair value hierarchy). Average daily borrowings of commercial paper during the first threenine months of 2021 and full year 2020 were $120.3$151.7 million and $83.2 million, respectively, with weighted average interest rates of approximately 0.2% and 0.4%, respectively.

AB has a $200.0 million committed, unsecured senior revolving credit facility (the "Revolver") with a leading international bank, which matures on November 16, 2021.2021 and we do not expect to renew this facility. The Revolver is available for AB's and SCB LLC's business purposes, including the provision of additional liquidity to meet funding requirements primarily related to SCB LLC's operations. Both AB and SCB LLC can draw directly under the Revolver and management expects to draw on the Revolver from time to time. AB has agreed to guarantee the obligations of SCB LLC under the Revolver. The Revolver contains affirmative, negative and financial covenants that are identical to those of the Credit Facility. Borrowings under the Revolver bear interest at a rate per annum, which will be, at our option, a rate equal to an applicable margin, which is subject to adjustment based on the credit ratings of AB, plus one of the following indices: London Interbank Offered Rate; a floating base rate; or the Federal Funds rate. As of both March 31,September 30, 2021 and December 31, 2020, we had 0no amounts outstanding under the Revolver. Average daily borrowings under the Revolver during the first threenine months of 2021 and full year 2020 were $26.1$17.3 million and $16.5 million, respectively, with weighted average interest rates of approximately 1.1% and 1.6%, respectively.

On September 28, 2021, AB established a $100.0 million uncommitted line of credit with a financial institution. This line of credit matures on September 27, 2022 and is available for AB's and SCB LLC's business purposes. Both AB and SCB LLC can draw directly under this line. AB has agreed to guarantee the obligations of SCB LLC under this line of credit. As of September 30, 2021, we had no amounts outstanding under this line of credit and have not drawn on it since inception. Subsequent to September 30, 2021, we entered into 1 additional uncommitted line of credit (refer to Note 18 Subsequent Events for further details).

In addition, SCB LLC currently has 3 uncommitted lines of credit with 3 financial institutions. NaN of these lines of credit permit us to borrow up to an aggregate of approximately $165.0 million, with AB named as an additional borrower, while the other line has no stated limit.

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

Impact of COVID-19
General Economic Conditions
During the first quarter of 2020, COVID-19 significantly impacted the global economy. The impact has been profound, has continued through the first quarternine months of 2021, and may persist for months to come. While manymost businesses have re-opened, vaccinations are underway (particularlyprogressing in most portions of the U.S., the U.K. and Israel)world and leading economic indicators are showing signs of improvement,have improved significantly, the overall extent and duration of COVID-19's impact on businesses and economic activity generally remains unclear.
Governments around the world have responded to COVID-19 with economic stimulus measures, including a $2 trillion emergency relief bill passed in the U.S. during the first quarter of 2020, an additional $900 billion in aid passed during the fourth quarter of 2020, and the most recent $1.9 trillion COVID-19 relief package passed in the first quarter of 2021. Similar fiscal stimulus was passed by many governments around the world. These measures and possible additional stimulus and aid measures are intended to steady businesses and consumers until economic activity meaningfully recovers. The timing and magnitude of any such recovery, however, remains uncertain.

Various countries around the world, and certain areas in the U.S., have continued to experience surges in the rates of COVID-19 infections, which have resulted from the emergence and spread of mutated strains ofvirus variants (particularly the virus,"delta variant"), greatly increased social interactions, including at colleges and universities and social venues, after re-opening of economies, and decreased usage of mitigation techniques, such as mask wearingmask-wearing and social distancing, in some areas.combination with large portions of the population remaining unvaccinated. These ongoing circumstances surrounding the virus may adversely affect consumer sentiment and the pacedurability of business re-openings, and they also may delay or slow economic recovery and possibly cause additional market volatility.volatility and even a new downturn.

AB Impact
At the onset of COVID-19 during the first quarter of 2020, we quickly responded in the various jurisdictions where we operate, including the U.S., the U.K., Tokyo, Hong Kong, Shanghai, Singapore and Taiwan. We implemented business continuity measures, including travel restrictions and a work-from-home requirement for almost all personnel (other than a relatively small number of employees whose physical presence in our offices was considered critical), which hasgenerally remained in place (except in our Asia-Pacific offices, most of which have reopened) throughout 2020 and the first quarternine months of 2021 to ensure operating continuity for all critical functions. During the third quarter of 2021, we began implementing gradual return to office programs for our U.S. and European offices. However, we continue to monitor the daily evolution of the pandemic, including the spread of the delta variant, in order to ensure the health and safety of our employees remains our top priority. We alsowill modify our return to office plans, as needed, to ensure the safety of our employees and to ensure that the highest safety and cleanliness protocols are followed. We believe that our business continuity plan and technology platform will continue to support the effectiveness of our employees working remotely to the extent that we continue that arrangement.
Additionally, we instituted a notification process in 2020, which persists today, for any employee who tests positive for COVID-19 or has been exposed to someone else who has tested positive. As the COVID-19 crisis has continued to evolve since the lockdown in the first quarter of 2020, certain key functions of the business, such as Risk Management, Business Continuity, Finance and Human Capital, have maintained constant communication and monitored the evolution of the pandemic to keep our employees safe and disseminate information regarding key developments. Additionally, weWe also continue to monitor communications from the World Health Organization and the U.S. Centers for Disease Control and Prevention to ensure we have current information.
WeFurthermore, we have continued to enhance our technology, which has increased the effectiveness of our remote work force. We have also continued to enhance our virtual programs to support business functions, such as training on cybersecurity and enhancements to our existing technology platforms.platforms, which has increased the effectiveness of our remote work force. There has been a heightened focus on the emotional well-being of our employees, and we have provided regular touch points with employees through virtual town halls and management communications. Additionally, we have maintained regular communications and updates on the virus and the Company's response, which are posted on the Company's internal website, to ensure transparent communication with our employees.
We continue to consider, and in some cases methodically implement, return to office programs for our U.S. and European offices. (As noted above, most of our Asia-Pacific offices re-opened in 2020.) In fact, we hope and expect to gradually bring our workforce back into the office, across each of our locations, early in the third quarter of 2021. However, we continue to monitor the daily evolution of the pandemic in order to ensure the health and safety of our employees remains our top priority. We will modify our return to office plans, as needed, to ensure the safety of our employees and to ensure that the highest safety and cleanliness protocols are followed. We believe that our business continuity plan and technology platform will continue to support the effectiveness of our employees working remotely.
The economic impact of COVID-19 and any additional declines in the financial markets could have a significant adverse effect on our AUM and revenues, particularly if economic activity does not continue to recover. Although countries throughout the world continue to grapple with re-opening their economies, this will continue to be a gradual process, and there is a significant risk that the opening process may be further interrupted or reversed if infection rates increase. Also, although unemployment rates have declined, they are still considered highsomewhat elevated and any reluctance of consumers to resume spending could do long-term damage to the

Index
global economy, which would have an adverse effect on our business. Additionally, as most of our workforce continues working remotely, at least part of the time, we are mindful of increased risk related to cybersecurity, which could significantly disrupt our business functions.
Ultimately, the return to normal business and economic activity will likely require the broad application of effective vaccines. The distribution of multiple safe, effective vaccines was initiated towards the end of the fourth quarter of 2020 and the distribution of such vaccines hasgenerally increased globally through the first quarternine months of 2021, particularly2021. However, the rate of new vaccinations in the U.S., the U.K. plateaued, and Israel. Furthermore, while issues persist around the speed, selective nature of those who are eligiblein some areas began to receive the vaccination, as well as logistical challenges regarding availability and distribution of the vaccines, most people in the U.S. who are at least 16 years of age and want to be vaccinated likely will be vaccinateddecrease, by the end of the second quarter of 2021. If global vaccination rates do not improve further, a significant risk will remain that COVID-19 and/or a variant thereof, could accelerate global health concerns and, in so doing, cause heightened market and economic turmoil in the future.

Executive Overview
Our total assets under management (“AUM”) as of March 31,September 30, 2021 were $697.2$742.2 billion, up $11.3$3.8 billion, or 1.6%0.5%, compared to December 31, 2020,June 30, 2021, and up $155.4$111.4 billion, or 28.7%17.7%, compared to March 31,September 30, 2020. During the firstthird quarter of 2021, AUM increased as a result of net inflows of $7.2 billion, offset by market depreciation of $3.4 billion (Retail net inflows of $6.6 billion, Private Wealth Management net inflows of $0.4 billion and Institutional net inflows of $0.2 billion). During the twelve months ended September 30, 2021, AUM increased as a result of market appreciation of $6.1$89.5 billion and net inflows of $5.2$21.9 billion (Retail net inflows of $2.7 billion, Private Wealth Management net inflows of $1.7 billion and Institutional net inflows of $0.8 billion).

Redemptions and terminations decreased sequentially from $13.7 billion to $2.9 billion. The significant sequential change in sales and redemptions primarily resulted from the second quarter of 2021 including $8.7 billion in sales and $10.0 billion in redemptions associated with a sale by Equitable Holdings, Inc ("EQH") to Venerable Holdings, of its legacy variable annuity assets, for which AB remained the preferred investment manager.

Retail AUM increased $5.1 billion, or 1.7%, to $298.8 billion during the third quarter of 2021, due to net inflows of $6.6 billion, offset by market depreciation of $1.5 billion.

Market Environment
Despite market gains through the majority of the third quarter, U.S. equity markets experienced a seasonal slowdown in September. The S&P 500 finished marginally higher, while both the Dow Jones Industrial Average and Nasdaq each finished the quarter in negative territory. The Federal Reserve signaled it would start tapering its asset purchases by the end of the year and any interest rate hikes will likely not commence until the tapering process is complete. In the U.K., natural gas and fuel shortages were prevalent towards the end of the third quarter. The supply bottlenecks coupled with labor shortages triggered a sharp rise in underlying inflation and led to concerns that the Bank of England may begin raising rates in the near future. In China, investor concerns grew over supply chain disruptions and recent power outages, which led to energy rationing. Furthermore, uncertainty remains around the path of future regulation, particularly as it relates to technology companies.

Index
Market Environment
U.S. equity markets remained strong during the first quarter of 2021, with the S&P 500, Dow Jones Industrial Average and Nasdaq each finishing the quarter in positive territory. The U.S. seeks to continue to emerge from the pandemic by accelerating progress on vaccinations combined with unprecedented levels of fiscal stimulus. The Federal Reserve has pledged to maintain its current accommodative monetary policy until inflation has exceeded their target for a sustained time period. In the U.K., the rapid roll-out of the vaccine is expected to facilitate relatively strong growth from the second quarter onwards, with Brexit-related trade frictions expected to ease starting in the second half of this year. Government stimulus should assist in keeping unemployment relatively low, while the Bank of England is likely to keep rates on hold during the recovery phase. In China, the market outlook remains positive, as a broader global re-opening appears to be benefiting the Chinese economy. Given the strong recovery from the pandemic, China will likely begin a slow and gradual tightening of their fiscal policy. While political tensions between China and the U.S. continue to linger, further escalation from the new U.S. administration in the near term seems unlikely.MiFID II

MiFID II
In Europe, MiFID II, which has been effective since 2018, has significantly modified how European broker-dealers can be compensated for research. These modifications have significantly reduced the overall research spend by many European buy-side firms, which has decreased the revenues we earn from these clients. If this trend continues, the revenues we earn from our European clients would deplete further.

Also, while MiFID II does not apply outside of Europe, competitive and client pressures may force buy-side firms operating outside of Europe to pay for research from their own resources instead of through bundled trading commissions. If this occurs, research budgets from those clients, as well as our sell-side revenues, may decrease further. Additionally, these pressures could force our buy-side operation to pay for research out of our own revenues instead of through bundled trading commissions, which could increase our firm’s expenses and decrease our operating income.

Lastly, although the impact of MiFID II is largely known, the ultimate, global impact is still uncertain.
Relationship with Equitable HoldingsEQH
AB and AXA
PriorEQH are collaborating to an initial public offering ("IPO")each firm's expected mutual benefit to improve the risk-adjusted yield for EQH's General Account by Equitable Holdings, Inc. (“EQH”)investing more assets at AB, including the utilization of AB's higher-fee, longer-duration alternative offerings. EQH has agreed to provide $10 billion in May of 2018,permanent capital1 over the next three years to build out AB’s private illiquid offerings, including private alternatives and private placements. We expect this anticipated capital from EQH was a wholly-owned subsidiary of AXA S.A. ("AXA"). Since the IPO, AXA has divested its ownership in EQH to less than 10% of the outstanding common stock of EQH as of March 31, 2021.

While we cannot at this time predict the full impact on AB of these transactions, such impact has included a reduction in the support AXA provided to AB in the past with respect to AB's investment management business, resulting in a modest decreasewill accelerate both organic and inorganic growth in our revenuesprivate alternatives business, allowing us to continue to deliver for our clients, employees, unitholders and ability to initiate new investment services.

other stakeholders.
Our ending AUM at March 31, 2021 reflects $11.8 billion in outflows resulting from AXA's redemption of certain low-fee fixed income mandates during 2020. No redemptions were made during the three months ended March 31, 2021. We currently anticipate AXA to redeem the majority of approximately $2 billion of additional assets during the three months ending June 30, 2021, bringing the total assets redeemed to approximately $14 billion. The revenue we earn from the management of these assets is not significant.

Relocation Strategy
We previously announced that we would establish our corporate headquarters in, and relocate approximately 1,250 jobs located in the New York metro area to, Nashville, TN. Our Nashville headquarters will househouses Finance, IT, Operations, Legal, Compliance, Internal Audit, Human Capital, and Sales and Marketing. We have been actively relocating jobs and expect this transition to take several more years. We are in the process of moving into our new headquarters office building located at 501 Commerce Street in downtown Nashville. We will continue to maintain a principal location in New York City, which will househouses our Portfolio Management, Sell-Side Research and Trading, and New York-based Private Wealth Management businesses.

We believe relocating our corporate headquarters to Nashville affords us the opportunity to provide an improved quality of life alternative for our employees and enable us to attract and recruit new talented employees to a highly desirable location while improving the long-term cost structure of the firm.

During the transition period, which began in 2018 and is expected to continue through 2024, we currently estimate that we will incur transition costs of approximately $145 million to $155 million. These costs include employee relocation, severance, recruitment, and overlapping compensation and occupancy costs. Over this same period, we expect to realize total expense savings of approximately $205 million to $215 million, an amount greater than the total transition costs.million. However, we did incur
30

Index
some transition costs before we began to realize expense savings. For the period beginning in 2018 and ending in the fourth quarter of 2020, we incurred $70 million of cumulative transition costs compared to $46 million of cumulative savings. In addition, we incurred $7$20 million of transition costs for the threenine months ended March 31,September 30, 2021 compared to $10$31 million of expense savings, resulting in an overall net savings of $3$11 million for the period. We currently anticipate an EPU increase in 2021 of approximately $0.02$0.04 resulting from our relocation strategy, which compares to the $0.01 EPU increase that occurred in 2020. We also expect to achieve EPU accretion in each year thereafter. Beginning in 2025, once the transition period has been completed, we estimate ongoing annual expense savings towards the upper end of the range ofapproximately $75 million to $80 million, which will result from a combination of occupancy and compensation-related savings. Our estimates for both the transition costs and the corresponding expense savings are based on our current assumptions of employee relocation costs, severance, and overlapping compensation and occupancy costs. In addition, our estimates for both the timing of when we incur transition costs and realize the related expense savings are based on our current relocation implementation plan and the timing for execution of each phase. The actual total charges we eventually record, the related expense savings we realize, and timing of EPU impact may differ from our current estimates as we implement each phase of our headquarters relocation.

1Permanent capital means investment capital of indefinite duration which may be withdrawn under certain conditions. Although EQH has indicated its intention over time to provide this investment capital to AB, which is mutually beneficial to both firms, it has no binding commitment to do so.

During October 2018, we signed a lease, which commenced in the fourth quarter of 2020, relating to 218,976 square feet of space at our new Nashville headquarters. Our estimated total base rent obligation (excluding taxes, operating expenses and utilities) over the 15-year initial lease term is $134 million.

Although we have presented our transition costs and annual expense savings with numerical specificity, and we believe these targets to be reasonable as of the date of this report, the uncertainties surrounding the assumptions we discuss above create a significant risk that these targets may not be achieved.  Accordingly, the expenses we actually incur and the savings we actually realize may differ from our targets, particularly if actual events adversely differ from one or more of our key assumptions.  The transition costs and expense savings, together with their underlying assumptions, are Forward-Looking Statements and can be affected by any of the factors discussed in “Risk“Risk Factors” and “Cautions“Cautions Regarding Forward-Looking Statements” in this 10-Q and our 2020 10-K. We strongly caution investors not to place undue reliance on any of these assumptions or our cost and expense targets.  Except as may be required by applicable securities laws, we are not under any obligation, and we expressly disclaim any obligation, to update or alter any assumptions, estimates, financial goals, targets, projections or other related statements that we may make.

Units Outstanding

Each quarter, we consider whether to implement a plan to repurchase AB Holding Units pursuant to Rules 10b5-1 and 10b-18 under the Exchange Act. A plan of this type allows a company to repurchase its shares at times when it otherwise might be prevented from doing so because of self-imposed trading blackout periods or because it possesses material non-public information. Each broker we select has the authority under the terms and limitations specified in the plan to repurchase AB Holding Units on our behalf. Repurchases are subject to regulations promulgated by the SEC, as well as certain price, market volume and timing constraints specified in the plan. The plan adopted during the firstthird quarter of 2021 expired at the close of business on April 28,October 27, 2021. We may adopt additional plans in the future to engage in open-market purchases of AB Holding Units to help fund anticipated obligations under our incentive compensation award program and for other corporate purposes.

Cash Distributions

We are required to distribute all of our Available Cash Flow, as defined in the AB Partnership Agreement, to our Unitholders and the General Partner. Available Cash Flow typically is the adjusted diluted net income per unit for the quarter multiplied by the number of general and limited partnership interests at the end of the quarter. In future periods, management anticipates that Available Cash Flow will continue to be based on adjusted diluted net income per unit, unless management determines, with concurrence of the Board of Directors, that one or more adjustments that are made for adjusted net income should not be made with respect to the Available Cash Flow calculation. See Note 6 to our consolidated financial statements contained in Item 1 for a description of Available Cash Flow.

Management Operating Metrics

We are providing the non-GAAP measures “adjusted net revenues,” “adjusted operating income” and “adjusted operating margin” because they are the principal operating metrics management uses in evaluating and comparing period-to-period operating performance. Management principally uses these metrics in evaluating performance because they present a clearer picture of our operating performance and allow management to see long-term trends without the distortion primarily caused by long-term incentive compensation-related mark-to-market adjustments, real estate charges and other adjustment items. Similarly, we believe that these management operating metrics help investors better understand the underlying trends in our results and, accordingly, provide a valuable perspective for investors.

These non-GAAP measures are provided in addition to, and not as substitutes for, net revenues, operating income and operating
margin, and they may not be comparable to non-GAAP measures presented by other companies. Management uses both accounting principles generally accepted in the United States of America ("US GAAP") and non-GAAP measures in evaluating our financial performance. The non-GAAP measures alone may pose limitations because they do not include all of our revenues and expenses.

Adjusted Net Revenues

Net Revenue, as adjusted, is reduced to exclude all of the company's distribution revenues, which are recorded as a separate line
item on the consolidated statement of income, as well as a portion of investment advisory services fees received that is used to pay distribution and servicing costs. For certain products, based on the distinct arrangements, certain distribution fees are collected by us and passed through to third-party client intermediaries, while for certain other products, we collect investment advisory services fees and a portion is passed through to third-party client intermediaries. In both arrangements, the third-party client intermediary owns the relationship with the client and is responsible for performing services and distributing the product to the client on our behalf. We believe offsetting distribution revenues and certain investment advisory services fees is useful for our investors and other users of our financial statements because such presentation appropriately reflects the nature of these costs as pass-through payments to third parties that perform functions on behalf of our sponsored mutual funds and/or shareholders of these funds. Distribution-related adjustments fluctuate each period based on the type of investment products sold, as well as the average AUM over the period. Also, we adjust distribution revenues for the amortization of deferred sales commissions as these costs, over time, will offset such revenues.

We adjust investment advisory and services fees and other revenues for pass through costs, primarily related to our transfer agent and shareholder servicing fees. These fees do not affect operating income, but they do affect our operating margin. As such, we exclude these fees from adjusted net revenues.

We adjust for the revenue impact of consolidating company-sponsored investment funds by eliminating the consolidated company-sponsored investment funds' revenues and including AB's fees from such consolidated company-sponsored investment funds and AB's investment gains and losses on its investments in such consolidated company-sponsored investment funds that were eliminated in consolidation.

Index

Also, adjusted net revenues exclude investment gains and losses and dividends and interest on employee long-term incentive compensation-related investments.

Lastly, during the first quarter of 2020, we wrote-off an investment that had been received in exchange for the sale of software technology, bringing the balance to zero. Previously, we had been excluding the value of this investment from adjusted net revenues.

Adjusted Operating Income

Adjusted operating income represents operating income on a US GAAP basis excluding (1) real estate charges (credits), (2) the impact on net revenues and compensation expense of the investment gains and losses (as well as the dividends and interest) associated with employee long-term incentive compensation-related investments, (3) our CEO'ssenior management's EQH award compensation, as discussed below, (4) the write-down of an investment (discussed immediately above), (5) acquisition-related expenses, and (6) the impact of consolidated company-sponsored investment funds.

Real estate charges (credits) incurred have been excluded because they are not considered part of our core operating results when comparing financial results from period to period and to industry peers. Real estate charges (credits) incurred during the fourth quarter of 2019 through the fourth quarter of 2020, while excluded in the period in which the charges (credits) were recorded, are included ratably over the remaining applicable lease term.

Prior to 2009, a significant portion of employee compensation was in the form of long-term incentive compensation awards that were notionally invested in AB investment services and generally vested over a period of four years. AB economically hedged the exposure to market movements by purchasing and holding these investments on its balance sheet. All such investments had vested as of year-end 2012 and the investments have been delivered to the participants, except for those investments with respect to which the participant elected a long-term deferral. Fluctuation in the value of these investments, which also impacts compensation expense, is recorded within investment gains and losses on the income statement. Management believes it is useful to reflect the offset achieved from economically hedging the market exposure of these investments in the calculation of adjusted operating income and adjusted operating margin. The non-GAAP measures exclude gains and losses and dividends and interest on employee long-term incentive compensation-related investments included in revenues and compensation expense.

The board of directors of EQH granted to Seth P. Bernstein, (“CEO”), our President and Chief Executive Officer,CEO, equity awards in connection with EQH's IPOIPO. Additionally, equity awards were granted to Mr. Bernstein and Mr. Bernstein'sother members of AB's senior management for their membership on the EQH Management Committee. Mr. BernsteinThese individuals may receive additional equity or cash compensation from EQH in the future related to histheir service on the Management Committee. Any awards granted to Mr. Bernsteinthese individuals by EQH are recorded as compensation expense in AB’s consolidated statement of income. The compensation expense associated with these awards has been excluded from our non-GAAP measures because they are non-cash and are based upon EQH's, and not AB's, financial performance.
The write-off of the investment discussed above in Adjusted net revenuesNet Revenues has been excluded due to its non-recurring nature and because it is not part of our core operating results.
Acquisition-related expenses have been excluded because they are not considered part of our core operating results when comparing financial results from period to period and to industry peers.
We adjusted for the operating income impact of consolidating certain company-sponsored investment funds by eliminating the consolidated company-sponsored funds' revenues and expenses and including AB's revenues and expenses that were eliminated in consolidation. We also excluded the limited partner interests we do not own.
Adjusted Net Income and Adjusted Diluted Net Income per AB Unit

As previously discussed, our quarterly distribution is typically our adjusted diluted net income per unit (which is derived from adjusted net income) for the quarter multiplied by the number of general and limited partnership interests at the end of the quarter. Adjusted income taxes, used in calculating adjusted net income, are calculated using the GAAP effective tax rate adjusted for non-GAAP income tax adjustments.

Adjusted Operating Margin

Adjusted operating margin allows us to monitor our financial performance and efficiency from period to period without the volatility noted above in our discussion of adjusted operating income and to compare our performance to industry peers on a basis that better reflects our performance in our core business. Adjusted operating margin is derived by dividing adjusted operating income by adjusted net revenues.

Investment Advisory and Services Fees

Investment advisory and services fees are the largest component of our revenues. These fees generally are calculated as a percentage of the value of AUM as of a specified date, or as a percentage of the value of average AUM for the applicable billing period, and vary with the type of investment service, the size of account and the total amount of assets we manage for a particular client. Accordingly, fee income generally increases or decreases as AUM increase or decrease and is affected by market appreciation or depreciation, the addition of new client accounts or client contributions of additional assets to existing accounts, withdrawals of assets from and termination of client accounts, purchases and redemptions of mutual fund shares, shifts of assets between accounts or products with different fee structures, and acquisitions. Our average basis points realized (investment advisory and services fees divided by average AUM) generally approximate 30 to 110105 basis points for actively-managed equity services, 10 to 70 basis points for actively-managed fixed income services and 2 to 20 basis points for
42

Index
passively-managed services. Average basis points realized for other services could range from 4 basis points for certain Institutional third party managed services to over 100 basis points for certain Retail and Private Wealth Management alternative services. These ranges include all-inclusive fee arrangements (covering investment management, trade execution and other services) for our Private Wealth Management clients.

We calculate AUM using established market-based valuation methods and fair valuation (non-observable market) methods. Market-based valuation methods include: last sale/settle prices from an exchange for actively-traded listed equities, options and futures; evaluated bid prices from recognized pricing vendors for fixed income, asset-backed or mortgage-backed issues; mid prices from recognized pricing vendors and brokers for credit default swaps; and quoted bids or spreads from pricing vendors and brokers for other derivative products. Fair valuation methods include: discounted cash flow models or any other methodology that is validated and approved by our Valuation Committee (see paragraph immediately below for more information regarding our Valuation Committee). Fair valuation methods are used only where AUM cannot be valued using market-based valuation methods, such as in the case of private equity or illiquid securities.

The Valuation Committee, which consists of senior officers and employees, is responsible for overseeing the pricing and valuation of all investments held in client and AB portfolios. The Valuation Committee has adopted a Statement of Pricing Policies describing principles and policies that apply to pricing and valuing investments held in these portfolios. We also have a Pricing Group, which reports to the Valuation Committee and is responsible for overseeing the pricing process for all investments.
 
We sometimes charge our clients performance-based fees. In these situations, we charge a base advisory fee and are eligible to earn an additional performance-based fee or incentive allocation that is calculated as either a percentage of absolute investment results or a percentage of investment results in excess of a stated benchmark over a specified period of time. Some performance-based fees include a high-watermark provision, which generally provides that if a client account underperforms relative to its performance target (whether absolute or relative to a specified benchmark), it must gain back such underperformance before we can collect future performance-based fees. Therefore, if we fail to achieve our performance target for a particular period, we will not earn a performance-based fee for that period and, for accounts with a high-watermark provision, our ability to earn future performance-based fees will be impaired. We are eligible to earn performance-based fees on 5.6%6.3%, 8.8% and 0.8%0.7% of the assets we manage for institutional clients, private wealth clients and retail clients, respectively (in total, 4.2%4.4% of our AUM).

Bernstein Research Services

We earn revenues for providing investment research to, and executing brokerage transactions for, institutional clients. These clients compensate us principally by directing us to execute brokerage transactions on their behalf, for which we earn commissions, and to a lesser extent, but increasingly, by paying us directly for research through commission sharing agreements or cash payments.
Revenues from Bernstein Research Services for the three months ended March 31,September 30, 2021 decreased $10.2increased $14.8 million, or 7.9%15.0%, from the three months ended March 31,September 30, 2020, due to reducedhigher customer trading activity and research payments across all regions. For the nine months ended September 30, 2021, Bernstein Research Services revenue decreased $3.3 million, or 1.0%, compared to the nine months ended September 30, 2020 due to lower trading activity driven by fewer trading days and decreasedlower global market volatility as compared to the COVID-related significant surge in trading volume experienced duringfor the threenine months ended March 31,September 30, 2020.

This was partially offset by higher research payments.

Distribution Revenues

Two of our subsidiaries act as distributors and/or placement agents of company-sponsored mutual funds and receive distribution services fees from certain of those funds as partial reimbursement of the distribution expenses they incur. Period-over-period fluctuations of distribution revenues typically are in line with fluctuations of the corresponding average AUM of these mutual funds.

Distribution revenues for the three months ended March 31,September 30, 2021 increased $16.7$34.9 million, or 12.8%25.7%, from the three months ended March 31,September 30, 2020, primarily due to the corresponding average AUM of these mutual funds increasing 12.4%.18.8%, as well as an increase in the overall portfolio fee rate.

Employee Compensation and Benefits

Employee compensation and benefits consist of base compensation (including salaries and severance), annual short-term incentive compensation awards (cash bonuses), annual long-term incentive compensation awards, commissions, fringe benefits and other employment costs (including recruitment, training, temporary help and meals).

Compensation expense as a percentage of net revenues was 40.3%39.7% and 41.4%39.8% for the three months ended March 31,September 30, 2021 and 2020, respectively. Compensation expense as a percentage of net revenues was 40.2% and 40.4% for the nine months ended September 30, 2021 and 2020, respectively. Compensation expense generally is determined on a discretionary basis and is primarily a function of our firm’s current-year financial performance. The amounts of incentive compensation we award are designed to motivate, reward and retain top talent while aligning our executives' interests with the interests of our Unitholders. Senior management, with the approval of the Compensation and Workplace Practices Committee of the Board of Directors of AllianceBernstein Corporation (“Compensation Committee”), periodically confirms that the appropriate metric to consider in determining the amount of incentive compensation is the ratio of adjusted employee compensation and benefits expense to adjusted net revenues. Adjusted net revenues used in the adjusted compensation ratio are the same as the adjusted net revenues presented as a non-GAAP measure (discussed earlier in this Item 2). Adjusted employee compensation and benefits expense is total employee compensation and benefits expense minus other employment costs such as recruitment, training, temporary help and meals (which were 0.7% and 1.0%, respectively,was 0.9% of adjusted net revenues for the three months ended March 31,September 30, 2021 and 0.8% for the nine months ended September 30, 2021), and excludes the impact of mark-to-market vesting expense, as well as dividends and interest expense, associated with employee long-term incentive compensation-related investments and the amortization expense associated with the awards issued by EQH to some of our firm's CEOsenior management relating to his roletheir roles as a membermembers of the EQH Management Committee. Senior management, with the approval of the Compensation Committee, has established as an objective that adjusted employee compensation and benefits expense generally should not exceed 50% of our adjusted net

Index
revenues, except in unexpected or unusual circumstances. Also, our adjusted compensation ratio reflects a balancing of the need to keep compensation levels competitive with industry peers in order to attract, motivate and retain highly-qualified talent with the need to maintain strong operating leverage in our business. The Compensation Committee works with management to help ensure both needs are sufficiently addressed. Our ratio of adjusted compensation expense as a percentage of adjusted net revenues was 48.5%48.0% for the three months ended March 31,September 30, 2021 and 2020. Our ratio of adjusted compensation expense as a percentage of adjusted net revenues was 48.3% for the nine months September 30, 2021 and 2020.

For the three months ended March 31,September 30, 2021, employee compensation and benefits expense increased $43.8$76.1 million, or 12.1%21.3%, compared to the three months ended March 31,September 30, 2020, primarily due to higher incentive compensation of $39.1$50.7 million, higher base compensation of $11.8 million, higher commissions of $5.8 million, higher fringes of $4.2$5.3 million and higher other employment costs of $2.5 million. For the nine months ended September 30, 2021, employee compensation and benefits expense increased $206.0 million, or 19.3%, compared to the nine months ended September 30, 2020, primarily due to higher incentive compensation of $149.1 million, higher base compensation of $1.9$27.5 million, partially offset by lowerhigher fringes of $15.0 million, higher commissions of $12.8 million and higher other employment costs of $1.6$1.7 million.

Income Taxes

AB, a private limited partnership, is not subject to federal or state corporate income taxes. However, AB is subject to a 4.0% New York City unincorporated business tax (“UBT”). Our domestic corporate subsidiaries are subject to federal, state and local income taxes and generally are included in the filing of a consolidated federal income tax return. Separate state and local income tax returns also are filed. Foreign corporate subsidiaries generally are subject to taxes in the jurisdictions where they are located.

Income tax expense for the three months ended March 31,September 30, 2021 increased $7.3$6.9 million, or 76.7%76.4%, compared to the three months ended March 31,September 30, 2020. Income tax expense for the nine months ended September 30, 2021 increased $15.3 million, or 51.1%, compared to the nine months ended September 30, 2020. The increase was primarilyin income tax expense is due to higher foreign income in both the three and nine month periods ended September 30, 2021, which carries a higher effective tax rate for the three months ended March 31, 2021 of 6.4% compared to 5.3% for the corresponding period in 2020, driven by an increase in one-time discrete items.than domestic income. There were no material changes to uncertain tax positions (FIN 48 reserves) or valuation allowances against deferred tax assets for the three and nine months ended March 31,September 30, 2021.

Net Income (Loss) of Consolidated Entities Attributable to Non-Controlling Interests

Net income (loss) of consolidated entities attributable to non-controlling interests primarily consists of limited partner interests owned by other investors in our consolidated company-sponsored investment funds. For the three months ended March 31,September 30, 2021, we had $0.3$1.1 million ofin net losses of consolidated entities attributable to non-controlling interests compared to net lossesgains of $25.6$0.1 million for the three months ended March 31,September 30, 2020. For the nine months ended September 30, 2021, we had $2.2 million of net gains of consolidated entities attributable to non-controlling interests compared to net losses of $4.6 million for the nine months ended September 30, 2020. Fluctuations period-to-period result primarily from the number of consolidated company-sponsored investment funds and their respective market performance.

CAPITAL RESOURCES AND LIQUIDITY

Cash flows from operating activities primarily include the receipt of investment advisory and services fees and other revenues offset by the payment of operating expenses incurred in the normal course of business. Our cash flows from operating activities have historically been positive and sufficient in supporting our operations. We do not anticipate this to change in the foreseeable future. Cash flows from investing activities generally consist of small capital expenditures and, when applicable, business acquisitions. Cash flows from financing activities primarily consist of issuance and repayment of debt and the repurchase of AB Holding units to fund our long-term deferred compensation plans. We are required to distribute all of our Available Cash Flow to our Unitholders and the General Partner.

During the first threenine months of 2021, net cash provided by operating activities was $328.0 million,$1.4 billion, compared to $285.9 million$1.6 billion during the corresponding 2020 period. The change reflects net activity of our consolidated funds of $325.6 million and an increase in other assets of $222.9 million, partially offset by higher earnings of $204.6 million, an increase in accrued compensation and benefits of $101.0 million, an increase in accounts payable and accrued expenses of $41.1 million and lower net purchases of broker-dealer investments of $71.1 million, a

During the first threenine months of 2021, net cash used in investing activities was $19.4$55.9 million, compared to $14.8$25.9 million during the corresponding 2020 period. The change is primarily due to higher purchases of furniture, equipment and leasehold improvements of $12.3$39.7 million, partially offset by lower cash paid for acquisitions of $7.7$9.8 million.

Debt and Credit Facilities

See Note 16 and Note 18 to AB’s condensed consolidated financial statements contained in Item 1, for disclosures relating to our debt and credit facilities.

Our financial condition and access to public and private debt markets should provide adequate liquidity for our general business needs. Management believes that cash flow from operations and the issuance of debt and AB Units or AB Holding Units will provide us with the resources we need to meet our financial obligations. See “Cautions Regarding Forward-Looking Statements.

COMMITMENTS AND CONTINGENCIES

AB’s capital commitments, which consist primarily of operating leases for office space, generally are funded from future operating cash flows.

We have signed a lease which commences in 2024, relating to approximately 166,000 square feet of space in New York City. Our estimated total base rent obligation (excluding taxes, operating expenses and utilities) over the 20-year lease term is approximately $393.0 million.

During 2010, as general partner of AllianceBernstein U.S. Real Estate L.P. (“Real Estate Fund”), we committed to invest $25.0 million in the Real Estate Fund. As of March 31,September 30, 2021, we had funded $22.4 million of this commitment. During 2014, as general partner of AllianceBernstein U.S. Real Estate II L.P. (“Real Estate Fund II”), we committed to invest $27.3 million, as amended in 2020, in Real Estate Fund II. As of March 31,September 30, 2021, we had funded $20.8$21.0 million of this commitment.

CAUTIONS REGARDING FORWARD-LOOKING STATEMENTS

Certain statements provided by management in this report and in the portion of AB’s Form 10-Q attached hereto as Exhibit 99.1 are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements are subject to risks, uncertainties and other factors that could cause actual results to differ materially from future results expressed or implied by such forward-looking statements. The most significant of these factors include, but are not limited to, the following: the performance of financial markets, the investment performance of sponsored investment products and separately-managed accounts, general economic conditions, industry trends, future acquisitions, integration of acquired companies, competitive conditions and government regulations, including changes in tax regulations and rates and the manner in which the earnings of publicly-traded partnerships are taxed. We caution readers to carefully consider such factors. Further, these forward-looking statements speak only as of the date on which such statements are made; we undertake no obligation to update any forward-looking statements to reflect events or circumstances after the date of such statements. For further information regarding these forward-looking statements and the factors that could cause actual results to differ, see “Risk Factors” in Part I, Item 1A of our Form 10-K for the year ended December 31, 2020 and Part II, Item 1A in this Form 10-Q. Any or all of the forward-looking statements that we make in our Form 10-K, this Form 10-Q, other documents we file with or furnish to the SEC, and any other public statements we issue, may turn out to be wrong. It is important to remember that other factors besides those listed in “Risk Factors” and those listed below could also adversely impact our revenues, financial condition, results of operations and business prospects.

The forward-looking statements referred to in the preceding paragraph, most of which directly affect AB but also affect AB Holding because AB Holding’s principal source of income and cash flow is attributable to its investment in AB, include statements regarding:

Our belief that the cash flow AB Holding realizes from its investment in AB will provide AB Holding with the resources it needs to meet its financial obligations: AB Holding’s cash flow is dependent on the quarterly cash distributions it receives from AB. Accordingly, AB Holding’s ability to meet its financial obligations is dependent on AB’s cash flow from its operations, which is subject to the performance of the capital markets and other factors beyond our control.

Our financial condition and ability to access the public and private capital markets providing adequate liquidity for our general business needs: Our financial condition is dependent on our cash flow from operations, which is subject to the performance of the capital markets, our ability to maintain and grow client assets under management and other factors beyond our control. Our ability to access public and private capital markets on reasonable terms may be limited by adverse market conditions, our firm’s credit ratings, our profitability and changes in government regulations, including tax rates and interest rates.

The outcome of litigation: Litigation is inherently unpredictable, and excessive damage awards do occur. Though we have stated that we do not expect any pending legal proceedings to have a material adverse effect on our results of operations, financial condition or liquidity, any settlement or judgment with respect to a legal proceeding could be significant and could have such an effect.

The possibility that we will engage in open market purchases of AB Holding Units to help fund anticipated obligations under our incentive compensation award program: The number of AB Holding Units AB may decide to buy in future periods, if any, to help fund incentive compensation awards depends on various factors, some of which are beyond our control, including the fluctuation in the price of an AB Holding Unit (NYSE: AB) and the availability of cash to make these purchases.

Our determination that adjusted employee compensation expense should not exceed 50% of our adjusted net revenues:  Aggregate employee compensation reflects employee performance and competitive compensation levels. Fluctuations in our revenues and/or changes in competitive compensation levels could result in adjusted employee compensation expense exceeding 50% of our adjusted net revenues.

Our Relocation Strategy: While the expenses, expense savings and EPU impact we expect will result from our Relocation Strategy are presented with numerical specificity, and we believe these figures to be reasonable as of the date of this report, the uncertainties surrounding the assumptions on which our estimates are based create a significant risk that our current estimates may not be realized. These assumptions include:
the amount and timing of employee relocation costs, severance and overlapping compensation and occupancy costs we experience; and
the timing for execution of each phase of our relocation implementation plan.

The Adverse Impact of COVID-19: The severity of any possible adverse impact on our AUM and revenues of any new economic downturn caused by a possible resurgence of the COVID-19 pandemic willwould depend on the depth and length of theany such downturn and its impact on the companies in which we invest. Our conclusions about the possible continuing adverse impact on us isare based on our assumptions that the recovery willfrom any such possible new economic downturn would be gradual and that there willcould again be significant, lasting high unemployment and economic damage. We believe that these assumptions are reasonable, but they may not be correct and economic conditions likely will differ from our assumptions.
Item 3.     Quantitative and Qualitative Disclosures About Market Risk

There have been no material changes in AB’s market risk from the information provided under “Quantitative and Qualitative Disclosures About Market Risk” in Part II, Item 7A of AB's Form 10-K for the year ended December 31, 2020.
Item 4.     Controls and Procedures

Disclosure Controls and Procedures

Each of AB Holding and AB maintains a system of disclosure controls and procedures that is designed to ensure that information required to be disclosed in our reports under the Exchange Act is (i) recorded, processed, summarized and reported in a timely manner, and (ii) accumulated and communicated to management, including the Chief Executive Officer ("CEO") and the Chief Financial Officer ("CFO"), to permit timely decisions regarding our disclosure.

As of the end of the period covered by this report, management carried out an evaluation, under the supervision and with the participation of the CEO and the CFO, of the effectiveness of the design and operation of the disclosure controls and procedures. Based on this evaluation, the CEO and the CFO concluded that the disclosure controls and procedures are effective.
