Our principal services include: • Institutional Services – servicing our institutional clients, including private and public pension plans, foundations and endowments, insurance companies, central banks and governments worldwide, and affiliates such as Equitable Holdings, Inc.

We also provide distribution, shareholder servicing, transfer agency services and administrative services to the mutual funds we sponsor. Our high-quality, in-depth research is the foundation of our business. Our research disciplines include economic, fundamental equity, fixed income and quantitative research. In addition, we have expertise in multi-asset strategies, wealth management, environmental, social and corporate governance ("ESG"), and alternative investments. We provide a broad range of investment services with expertise in: • Actively-managed equity strategies, with global and regional portfolios across capitalization ranges, concentration ranges and investment strategies, including value, growth and core equities; • Actively-managed traditional and unconstrained fixed income strategies, including taxable and tax-exempt strategies; • Alternative investments, including hedge funds, fund of funds, direct lending, real estate and private equity; • Multi-asset solutions and services, including dynamic asset allocation, customized target-date funds and target-risk funds; and • Some passive management, including index and enhanced index strategies. Organization As of March 31, 2022, EQH owned approximately 4.0% of the issued and outstanding units representing assignments of beneficial ownership of limited partnership interests in AllianceBernstein Holding L.P. (“AB Holding Units”). AllianceBernstein Corporation (an indirect wholly-owned subsidiary of EQH, “General Partner”) is the general partner of both AllianceBernstein Holding L.P. (“AB Holding”) and AB. AllianceBernstein Corporation owns 100,000 general partnership units in AB Holding and a 1.0% general partnership interest in AB. As of March 31, 2022, the ownership structure of AB, including limited partnership units outstanding as well as the general partner's 1.0% interest, was as follows: EQH and its subsidiaries 63.0 % AB Holding 36.3 Unaffiliated holders 0.7 100.0 % Including both the general partnership and limited partnership interests in AB Holding and AB, EQH and its subsidiaries had an approximate 64.5% economic interest in AB as of March 31, 2022. 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, 2021 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 SEC. 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/or 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 Certain prior period amounts have been reclassified to conform to the current period's presentation. Amounts previously presented on the Statement of Cash Flows as (increase) decrease in right-of-use assets and increase (decrease) in lease liabilities during 2021 are now presented net as "Cash payments to relieve operating lease liabilities". Non-cash lease expense under adjustments to reconcile net income to net cash provided by operating activities formerly classified as "Depreciation and other amortization" during 2021 are now classified separately on the Statement of Cash Flows as "Non-cash lease expense". Amounts previously classified under Financing "Other" related to non-cash accretion expense associated with our contingent payment arrangements during 2021 have been reclassified to non-cash "Other, net" under adjustments to reconcile net income to net cash provided by operating activities. Subsequent Events We have evaluated subsequent events through the date that these financial statements were filed with the SEC and did not identify any subsequent events that would require disclosure in these financial statements.

Long-term Incentive Compensatio

Share-based Payment Arrangement [Abstract]
Long-term Incentive Compensation Plans	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 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 and retention of AB Holding Units for the three months ended March 31, 2022 and 2021 consisted of the following: Three Months Ended March 31, 2022 2021 (in millions) Total amount of AB Holding Units Purchased/Retained (1) 0.3 1.0 Total Cash Paid for AB Holding Units Purchased/Retained (1) $ 14.0 $ 37.4 Open Market Purchases of AB Holding Units Purchased (1) — 0.6 Total Cash Paid for Open Market Purchases of AB Holding Units (1) $ — $ 24.2 (1) Purchased on a trade date basis. The difference between open-market purchases and units retained reflects the retention of AB Holding Units from employees to fulfill statutory tax withholding requirements at the time of delivery of long-term incentive compensation awards. 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. We did not adopt a plan during the first quarter of 2022. 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 three months of 2022 and 2021, we awarded to employees and Eligible Directors 0.7 million and 3.4 million restricted AB Holding Unit awards, respectively. We use any AB Holding Units repurchased during the applicable period and newly-issued AB Holding Units to fund these awards.

Earnings Per Unit [Abstract]
Net Income per Unit	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.

Equity [Abstract]
Cash Distributions	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.

The rabbi trust and custodial account enable us 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. Regarding 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, 2022 and December 31, 2021, our total seed capital investments were $320.5 million and $379.0 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. The portion of unrealized gains (losses) related to equity securities, as defined by ASC 321-10, held as of March 31, 2022 and 2021 were as follows: Three Months Ended March 31, 2022 2021 (in thousands) Net (losses) gains recognized during the period $ (16,550) $ 4,887 Less: net gains recognized during the period on equity securities sold during the period 4,539 4,565 Unrealized (losses) gains recognized during the period on equity securities held $ (21,089) $ 322

Derivative Instruments	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 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 . The notional value and fair value as of March 31, 2022 and December 31, 2021 for derivative instruments (excluding derivative instruments relating to our options desk trading activities discussed below ) not designated as hedging instruments were as follows: Fair Value Notional Value Derivative Assets Derivative Liabilities (in thousands) March 31, 2022: Exchange-traded futures $ 100,466 $ 1,564 $ 1,895 Currency forwards 66,216 7,647 7,133 Interest rate swaps 10,683 545 652 Credit default swaps 159,622 9,572 4,883 Total return swaps 61,597 2,754 1,060 Option swaps 50,000 — 524 Total derivatives $ 448,584 $ 22,082 $ 16,147 December 31, 2021: Exchange-traded futures $ 131,876 $ 392 $ 1,186 Currency forwards 66,058 7,344 6,980 Interest rate swaps 13,483 497 833 Credit default swaps 155,757 6,594 6,967 Total return swaps 63,817 595 527 Option swaps 50,000 — 430 Total derivatives $ 480,991 $ 15,422 $ 16,923 As of March 31, 2022 and December 31, 2021, the derivative assets and liabilities are included in both receivables and payables to brokers and dealers on our condensed consolidated statements of financial condition. The gains and losses for derivative instruments (excluding our options desk trading activities discussed below ) for the three months ended March 31, 2022 and 2021 recognized in investment gains (losses) in the condensed consolidated statements of income were as follows: Three Months Ended March 31, 2022 2021 (in thousands) Exchange-traded futures $ 7,513 $ 1,135 Currency forwards 544 1,181 Interest rate swaps (73) 88 Credit default swaps 1,717 (522) Total return swaps 7,406 (907) Option swaps 2,625 1,361 Net gains on derivative instruments $ 19,732 $ 2,336 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, 2022 and December 31, 2021, we held $7.8 million and $2.9 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 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, 2022 and December 31, 2021, we delivered $6.5 million and $5.6 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.

Fair Value Disclosures [Abstract]
Fair Value	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. Assets and Liabilities Measured at Fair Value on a Recurring Basis Valuation of our financial instruments by pricing observability levels as of March 31, 2022 and December 31, 2021 was as follows (in thousands): Level 1 Level 2 Level 3 NAV Expedient (1) Other Total March 31, 2022: Money markets $ 122,582 $ — $ — $ — $ — $ 122,582 Securities segregated (U.S. Treasury Bills) — 1,692,536 — — — 1,692,536 Derivatives 1,564 20,518 — — — 22,082 Investments: Equity securities 125,428 28,052 119 144 — 153,743 Long exchange-traded options 445 — — — — 445 Limited partnership hedge funds (2) — — — — 54,725 54,725 Time deposits (3) — — — — 21,942 21,942 Other investments 7,861 — — — 4,767 12,628 Total investments 133,734 28,052 119 144 81,434 243,483 Total assets measured at fair value $ 257,880 $ 1,741,106 $ 119 $ 144 $ 81,434 $ 2,080,683 Securities sold not yet purchased: Short equities – corporate $ 3,427 $ — $ — $ — $ — $ 3,427 Short exchange-traded options 221 — — — — 221 Derivatives 1,895 14,252 — — — 16,147 Contingent payment arrangements — — 39,098 — — 39,098 Total liabilities measured at fair value $ 5,543 $ 14,252 $ 39,098 $ — $ — $ 58,893 Level 1 Level 2 Level 3 NAV Expedient (1) Other Total December 31, 2021: Money markets $ 151,156 $ — $ — $ — $ — $ 151,156 Securities segregated (U.S. Treasury Bills) — 1,503,828 — — — 1,503,828 Derivatives 392 15,030 — — — 15,422 Investments: Equity securities 144,917 39,284 126 145 — 184,472 Long exchange-traded options 1,893 — — — — 1,893 Limited partnership hedge funds (2) — — — — 50,920 50,920 Time deposits (3) — — — — 21,024 21,024 Other investments 9,094 — — — 6,015 15,109 Total investments 155,904 39,284 126 145 77,959 273,418 Total assets measured at fair value $ 307,452 $ 1,558,142 $ 126 $ 145 $ 77,959 $ 1,943,824 Securities sold not yet purchased: Short equities – corporate $ 1,054 $ — $ — $ — $ — $ 1,054 Short exchange-traded options 2,774 — — — — 2,774 Derivatives 1,186 15,737 — — — 16,923 Contingent payment arrangements — — 38,260 — — 38,260 Total liabilities measured at fair value $ 5,014 $ 15,737 $ 38,260 $ — $ — $ 59,011 (1) Investments measured at fair value using NAV (or its equivalent) as a practical expedient.

(3) Investments carried at amortized cost that are not measured at fair value in accordance with GAAP. Other investments included in Level 1 of the fair value hierarchy include our investment in a mutual fund measured at fair value ($7.9 million and $9.1 million as of March 31, 2022 and December 31, 2021, respectively). Other investments not measured at fair value include (i) investments in start-up companies that do not have a readily available fair value (these investments were $0.3 million as of March 31, 2022 and December 31, 2021), (ii) investments in equity method investees that are not measured at fair value in accordance with GAAP ($1.6 million and $2.9 million as of March 31, 2022 and December 31, 2021, respectively), and (iii) broker dealer exchange memberships that are not measured at fair value in accordance with GAAP ($2.8 million as of March 31, 2022 and December 31, 2021). 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. During the three months ended March 31, 2022 there were no transfers between Level 2 and Level 3 securities. The change in carrying value associated with Level 3 financial instruments carried at fair value, classified as equity securities, is as follows: Three Months Ended March 31, 2022 2021 (in thousands) Balance as of beginning of period $ 126 $ 125 Purchases — — Sales — — Realized gains (losses), net — — Unrealized (losses), net (7) (1) Balance as of end of period $ 119 $ 124 Realized and unrealized gains and losses on Level 3 financial instruments are recorded in investment gains and losses in the condensed consolidated statements of income. As part of acquisitions made by the Company, we may enter into contingent consideration arrangements as part of the purchase price. The change in carrying value associated with Level 3 financial instruments carried at fair value, classified as contingent payment arrangements, is as follows: Three Months Ended March 31, 2022 2021 (in thousands) Balance as of beginning of period $ 38,260 $ 27,750 Addition — 7,526 Accretion 838 797 Payments — — Balance as of end of period $ 39,098 $ 36,073 The liabilities were valued using expected revenue growth rates and discount rates. As of March 31, 2022, the expected revenue growth rates range from 2.0% to 83.9%, with a weighted average of 7.9%, calculated using cumulative revenues and range of revenue growth rates (excluding revenue growth from additional AUM contributed in year of acquisition). The discount rates ranged from 1.9% to 10.4%, with a weighted average of 7.0%, calculated using total contingent liabilities and range of discount rates. As of March 31, 2021 the expected revenue growth rates ranged from 2.0% to 135.6%, with a weighted average of 9.0%, calculated using cumulative revenues and a range of revenue growth rates (excluding revenue growth from additional AUM contributed from existing clients). The discount rates ranged from 1.9% to 20.0%, with a weighted average of 10.8%, calculated using total contingent liabilities and range of discount rates.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	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.

Consolidated Company-Sponsored Investment Funds [Abstract]
Consolidated Company-Sponsored Investment Funds	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 balances of consolidated VIEs included in our condensed consolidated statements of financial condition were as follows: March 31, 2022 December 31, 2021 (in thousands) Cash and cash equivalents $ 24,145 $ 90,326 Investments 486,926 613,025 Other assets 30,594 30,461 Total assets $ 541,665 $ 733,812 Liabilities $ 36,774 $ 87,000 Redeemable non-controlling interest 338,021 421,169 Partners' capital attributable to AB Unitholders 166,870 225,643 Total liabilities, redeemable non-controlling interest and partners' capital $ 541,665 $ 733,812 During the first quarter of 2022, we deconsolidated three funds in which we had a seed investment of approximately $55.1 million due to no longer having a controlling financial interest. Fair Value Cash and cash equivalents include cash on hand, demand deposits, overnight commercial paper and highly liquid investments with original maturities of three months or less. Due to the short-term nature of these instruments, the recorded value has been determined to approximate fair value. Valuation of consolidated company-sponsored investment funds' financial instruments by pricing observability levels as of March 31, 2022 and December 31, 2021 was as follows (in thousands): Level 1 Level 2 Level 3 Total March 31, 2022: Investments $ 84,737 $ 401,941 $ 248 $ 486,926 Derivatives 1,782 2,620 — 4,402 Total assets measured at fair value $ 86,519 $ 404,561 $ 248 $ 491,328 Derivatives 16,013 2,927 — 18,940 Total liabilities measured at fair value $ 16,013 $ 2,927 $ — $ 18,940 December 31, 2021: Investments $ 165,415 $ 444,253 $ 3,357 $ 613,025 Derivatives 622 5,265 — 5,887 Total assets measured at fair value $ 166,037 $ 449,518 $ 3,357 $ 618,912 Derivatives $ 16,291 $ 2,051 $ — $ 18,342 Total liabilities measured at fair value $ 16,291 $ 2,051 $ — $ 18,342 See Note 11 for 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. The change in carrying value associated with Level 3 financial instruments carried at fair value within consolidated company-sponsored investment funds was as follows: Three Months Ended March 31, 2022 2021 (in thousands) Balance as of beginning of period $ 3,357 $ 619 Deconsolidated funds (3,351) — Transfers (out) (6) (10) Purchases 248 119 Sales — (3) Realized gains, net — 3 Unrealized (losses), net — (11) Balance as of end of period $ 248 $ 717 The Level 3 securities primarily consist of corporate bonds that are vendor priced with no ratings available, bank loans, non-agency collateralized mortgage obligations and asset-backed securities. Transfers into and out of all levels of the fair value hierarchy are reflected at end-of-period fair values. Realized and unrealized gains and losses on Level 3 financial instruments are recorded in investment gains and losses in the condensed consolidated statements of income. Derivative Instruments As of March 31, 2022 and December 31, 2021, the VIEs held $14.5 million and $12.5 million (net), respectively, of futures, forwards and swaps within their portfolios. For the three months ended March 31, 2022 and 2021, we recognized $0.5 million of gains and $1.1 million of losses, respectively, on these derivatives. These gains and losses are recognized in investment gains (losses) in the condensed consolidated statements of income. As of March 31, 2022 and December 31, 2021, the VIEs held $1.5 million and $0.9 million, respectively, of cash collateral payable to trade counterparties. This obligation to return cash is reported in the liabilities of consolidated company-sponsored investment funds in our condensed consolidated statements of financial condition. As of March 31, 2022 and December 31, 2021, the VIEs delivered $2.5 million and $1.8 million, respectively, of cash collateral into brokerage accounts. The VIEs report this cash collateral in the consolidated company-sponsored investment funds cash and cash equivalents in our condensed consolidated statements of financial condition.

Debt Disclosure [Abstract]
Debt	Debt AB has an $800.0 million committed, unsecured senior revolving credit facility (the “Credit Facility”) with a group of commercial banks and other lenders, which matures on October 13, 2026. 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, 2022, 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 default, all amounts payable under the Credit Facility would automatically become immediately due and payable, and the lender’s commitments automatically would terminate. 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, 2022 and December 31, 2021, we had no amounts outstanding under the Credit Facility. Furthermore, during the first three months of 2022 and the full year 2021, 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, 2022 and December 31, 2021, AB had $850.0 million and $755.0 million outstanding under the EQH Facility, with interest rates of approximately 0.3% and 0.2%, respectively. Average daily borrowings on the EQH Facility for the first three months of 2022 and the full year 2021 were $645.4 million and $404.6 million, respectively, with a weighted average interest rate of approximately 0.2%. In addition to the EQH Facility, AB has a $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, 2022 and December 31, 2021, we had no amounts outstanding under the EQH Uncommitted Facility and have not drawn upon the facility since its inception. As of March 31, 2022 and December 31, 2021, we had no 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 three months of 2022 and full year 2021 were $257.0 million and $157.0 million, respectively, with weighted average interest rates of approximately 0.2% and 0.2%, respectively. AB had a $200.0 million committed, unsecured senior revolving credit facility (the "Revolver") with a leading international bank, which matured on November 16, 2021. Average daily borrowings under the Revolver for the full year 2021 were $13.3 million with a weighted average interest rate of approximately 1.1%.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	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, 2021 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 SEC.
Principles of Consolidation	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/or 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	ReclassificationsCertain prior period amounts have been reclassified to conform to the current period's presentation. Amounts previously presented on the Statement of Cash Flows as (increase) decrease in right-of-use assets and increase (decrease) in lease liabilities during 2021 are now presented net as "Cash payments to relieve operating lease liabilities". Non-cash lease expense under adjustments to reconcile net income to net cash provided by operating activities formerly classified as "Depreciation and other amortization" during 2021 are now classified separately on the Statement of Cash Flows as "Non-cash lease expense". Amounts previously classified under Financing "Other" related to non-cash accretion expense associated with our contingent payment arrangements during 2021 have been reclassified to non-cash "Other, net" under adjustments to reconcile net income to net cash provided by operating activities.
