Organization As of September 30, 2023, EQH owned approximately 3.6% 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 September 30, 2023, 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 60.3 % AB Holding 39.0 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 61.7% economic interest in AB as of September 30, 2023. 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, 2022 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.

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 and nine months ended September 30, 2023 and 2022 consisted of the following: Three Months Ended September 30, Nine Months Ended September 30, 2023 2022 2023 2022 (in millions) Total amount of AB Holding Units Purchased/Retained (1) 1.8 — 2.3 2.6 Total Cash Paid for AB Holding Units Purchased/Retained (1) $ 56.9 $ 1.0 $ 75.7 $ 107.7 Open Market Purchases of AB Holding Units Purchased (1) 1.8 — 1.8 2.3 Total Cash Paid for Open Market Purchases of AB Holding Units (1) $ 56.9 $ — $ 56.9 $ 92.7 (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. The plan adopted during the third quarter of 2023 expired at the close of business on October 25, 2023. We may adopt 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 nine months of 2023 and 2022, we awarded to employees and Eligible Directors 0.4 million and 0.8 million restricted AB Holding Unit awards, respectively. We use AB Holding Units repurchased during the applicable period and newly-issued AB Holding Units to fund these awards. During the first nine months of 2023 and 2022, AB Holding issued zero and 5,774 AB Holding Units, respectively, upon exercise of options to buy AB Holding Units. AB Holding used the proceeds of zero 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.

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.

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 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 September 30, 2023 and December 31, 2022, our total seed capital investments were $333.4 million and $309.6 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 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 September 30, 2023 and 2022 were as follows: Three Months Ended September 30, Nine Months Ended September 30, 2023 2022 2023 2022 (in thousands) Net (losses) gains recognized during the period $ (4,991) $ 2,603 $ 3,456 $ (31,275) Less: net gains recognized during the period on equity securities sold during the period 754 8,197 6,603 17,953 Unrealized (losses) recognized during the period on equity securities held $ (5,745) $ (5,594) $ (3,147) $ (49,228)

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 September 30, 2023 and December 31, 2022 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) September 30, 2023: Exchange-traded futures $ 155,467 $ 2,946 $ 9 Currency forwards 27,740 5,314 4,494 Interest rate swaps 19,350 671 483 Credit default swaps 170,418 13,130 5,234 Total return swaps 70,403 2,367 3 Option swaps 50,000 — 499 Total derivatives $ 493,378 $ 24,428 $ 10,722 December 31, 2022: Exchange-traded futures $ 154,687 $ 1,768 $ 162 Currency forwards 34,597 4,446 5,047 Interest rate swaps 16,847 386 262 Credit default swaps 225,671 17,507 7,302 Total return swaps 28,742 605 933 Option swaps 50,000 — 6 Total derivatives $ 510,544 $ 24,712 $ 13,712 As of September 30, 2023 and December 31, 2022, 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 and nine months ended September 30, 2023 and 2022 recognized in investment gains (losses) in the condensed consolidated statements of income were as follows: Three Months Ended September 30, Nine Months Ended September 30, 2023 2022 2023 2022 (in thousands) Exchange-traded futures $ 4,622 $ 9,388 $ 2,022 $ 23,342 Currency forwards 594 1,318 557 3,600 Interest rate swaps 93 45 144 (7) Credit default swaps (272) (1,079) (4,513) 5,358 Total return swaps 2,858 2,970 (843) 18,401 Option swaps 1,041 1,897 214 5,676 Net gains (losses) on derivative instruments $ 8,936 $ 14,539 $ (2,419) $ 56,370 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 September 30, 2023 and December 31, 2022, we held $13.5 million and $8.4 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 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 September 30, 2023 and December 31, 2022, we delivered $1.6 million and $4.2 million, respectively, of cash collateral into brokerage accounts. We report this cash collateral in cash and cash equivalents in our condensed consolidated statement 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 September 30, 2023 and December 31, 2022 was as follows (in thousands): Level 1 Level 2 Level 3 NAV Expedient (1) Other Total September 30, 2023: Money markets $ 171,192 $ — $ — $ — $ — $ 171,192 Securities segregated (U.S. Treasury Bills) — 927,934 — — — 927,934 Derivatives 2,945 21,483 — — — 24,428 Investments: Equity securities 116,893 25,077 122 1,468 — 143,560 Limited partnership hedge funds (2) — — — — 77,433 77,433 Time deposits (3) — — — — 7,262 7,262 Other investments 6,987 — — — 2,972 9,959 Total investments 123,880 25,077 122 1,468 87,667 238,214 Total assets measured at fair value $ 298,017 $ 974,494 $ 122 $ 1,468 $ 87,667 $ 1,361,768 Derivatives $ 10 $ 10,712 $ — $ — $ — $ 10,722 Contingent payment arrangements — — 251,522 — — 251,522 Total liabilities measured at fair value $ 10 $ 10,712 $ 251,522 $ — $ — $ 262,244 Level 1 Level 2 Level 3 NAV Expedient (1) Other Total December 31, 2022: Money markets $ 95,521 $ — $ — $ — $ — $ 95,521 Securities segregated (U.S. Treasury Bills) — 1,521,705 — — — 1,521,705 Derivatives 1,768 22,944 — — — 24,712 Investments: Equity securities 129,655 27,799 129 1,484 — 159,067 Limited partnership hedge funds (2) — — — — 42,526 42,526 Time deposits (3) — — — — 7,750 7,750 Other investments 6,689 — — — 1,486 8,175 Total investments 136,344 27,799 129 1,484 51,762 217,518 Total assets measured at fair value $ 233,633 $ 1,572,448 $ 129 $ 1,484 $ 51,762 $ 1,859,456 Derivatives $ 162 $ 13,550 $ — $ — $ — $ 13,712 Contingent payment arrangements — — 247,309 — — 247,309 Total liabilities measured at fair value $ 162 $ 13,550 $ 247,309 $ — $ — $ 261,021 (1) Investments measured at fair value using NAV (or its equivalent) as a practical expedient.

Other investments included in Level 1 of the fair value hierarchy include our investment in a mutual fund measured at fair value ($7.0 million and $6.7 million as of September 30, 2023 and December 31, 2022, respectively). Other investments not measured at fair value include (i) investment in a start-up company that does not have a readily available fair value (this investment was $0.3 million as of both September 30, 2023 and December 31, 2022) and (ii) broker dealer exchange memberships that are not measured at fair value in accordance with GAAP ($2.7 million and $1.2 million as of September 30, 2023 and December 31, 2022, respectively). 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. • 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 nine months ended September 30, 2023 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 September 30, Nine Months Ended September 30, 2023 2022 2023 2022 (in thousands) Balance as of beginning of period $ 121 $ 119 $ 129 $ 126 Unrealized gains (losses), net 1 1 (7) (6) Balance as of end of period $ 122 $ 120 $ 122 $ 120 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.

The discount rates range from 1.9% to 10.4%, with a weighted average of 4.6%, calculated using total contingent liabilities and range of discount rates. In the third quarter of 2022 we acquired CarVal and recorded a contingent consideration liability of $227.1 million. As of September 30, 2022, including the CarVal acquisition, the expected revenue growth rates ranged from 2.0% to 83.9%, with a weighted average of 11.5%, calculated using cumulative revenues and a range of revenue growth rates (excluding revenue growth from additional AUM contributed in the year of acquisition). The discount rates ranged from 1.9% to 10.4%, with a weighted average of 4.5%, 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 are able to 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. On December 14, 2022, four individual participants in the Profit Sharing Plan for Employees of AllianceBernstein L.P., (the "Plan") filed a class action complaint (the “Complaint”) in the U.S. District Court for the Southern District of New York against AB, current and former members of the Compensation and Workplace Practices Committee of the Board, and the Investment and Administrative Committees under the Plan. Plaintiffs, who seek to represent a class of all participants in the Plan from December 14, 2016 to the present, allege that defendants violated their fiduciary duties and engaged in prohibited transactions under the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), by including proprietary collective investment trusts as investment options offered under the Plan. The Complaint seeks unspecified damages, disgorgement and other equitable relief. AB is prepared to defend itself vigorously against these claims. While the ultimate outcome of this matter is currently not determinable given the matter remains in its early stages, we do not believe this litigation will have a material adverse effect on our results of operations, financial condition or liquidity. AB may be involved in various other 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 other matters, but we cannot currently estimate any such losses. Management, after consultation with legal counsel, currently believes that the outcome of any other 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 other 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.

Consolidated Company-Sponsored Investment Funds	9 Months Ended

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 and VOEs included in our condensed consolidated statements of financial condition were as follows: September 30, 2023 December 31, 2022 (in thousands) VIEs VOEs Total VIEs VOEs Total Cash and cash equivalents $ 13,247 $ — $ 13,247 $ 19,751 $ — $ 19,751 Investments 297,386 22,419 319,805 516,536 — 516,536 Other assets 13,516 918 14,434 44,424 — 44,424 Total assets $ 324,149 $ 23,337 $ 347,486 $ 580,711 $ — $ 580,711 Liabilities $ 13,363 $ 938 $ 14,301 $ 55,529 $ — $ 55,529 Redeemable non-controlling interest 176,307 6,627 182,934 368,656 — 368,656 Partners' capital attributable to AB Unitholders 134,479 15,772 150,251 156,526 — 156,526 Total liabilities, redeemable non-controlling interest and partners' capital $ 324,149 $ 23,337 $ 347,486 $ 580,711 $ — $ 580,711 During the nine-month period ended September 30, 2023, we deconsolidated three funds in which we had a seed investment of approximately $40.6 million as of December 31, 2022, due to no longer having a controlling financial interest. Changes in the redeemable non-controlling interest balance during the nine-month period ended September 30, 2023 are as follows (in thousands): Redeemable non-controlling interest as of December 31, 2022 $ 368,656 Deconsolidated funds (196,277) Changes in third-party seed investments in consolidated funds 10,555 Redeemable non-controlling interest as of September 30, 2023 $ 182,934 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 September 30, 2023 and December 31, 2022 was as follows (in thousands): Level 1 Level 2 Level 3 Total September 30, 2023: Investments - VIEs $ 50,467 $ 246,919 $ — $ 297,386 Investments - VOEs 22,419 — — 22,419 Derivatives - VIEs 343 1,568 — 1,911 Total assets measured at fair value $ 73,229 $ 248,487 $ — $ 321,716 Derivatives - VIEs 1,192 2,549 — 3,741 Total liabilities measured at fair value $ 1,192 $ 2,549 $ — $ 3,741 December 31, 2022: Investments - VIEs $ 129,706 $ 386,830 $ — $ 516,536 Derivatives - VIEs 1,529 6,023 — 7,552 Total assets measured at fair value $ 131,235 $ 392,853 $ — $ 524,088 Derivatives - VIEs $ 14,932 $ 6,608 $ — $ 21,540 Total liabilities measured at fair value $ 14,932 $ 6,608 $ — $ 21,540 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 September 30, Nine Months Ended September 30, 2023 2022 2023 2022 (in thousands) Balance as of beginning of period $ — $ — $ — $ 3,357 Deconsolidated funds — — — (3,351) Transfers (out) — — — (6) Purchases — — — 248 Sales — — — (248) Balance as of end of period $ — $ — $ — $ — 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 September 30, 2023 and December 31, 2022, the VIEs held $1.8 million and $14.0 million (net), respectively, of futures, forwards and swaps within their portfolios. For the three and nine months ended September 30, 2023, we recognized $3.3 million and $2.9 million of losses, respectively, on these derivatives. For the three and nine months ended September 30, 2022, we recognized $4.9 million and $10.1 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 September 30, 2023 and December 31, 2022, the VIEs held $0.6 million and $2.7 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 September 30, 2023 and December 31, 2022, the VIEs delivered $3.3 million and $5.4 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. As of September 30, 2023, the VOEs held no futures, forwards, options or swaps within their portfolios. As of September 30, 2023, the VOEs held no cash collateral payable to trade counterparties. As of September 30, 2023, the VOEs delivered no cash collateral in brokerage accounts. Offsetting Assets and Liabilities Offsetting of derivative assets of consolidated company-sponsored investment funds as of September 30, 2023 and December 31, 2022 was as follows: Gross Amounts of Recognized Assets Gross Amounts Offset in the Statement of Financial Condition Net Amounts of Assets Presented in the Statement of Financial Condition Financial Cash Collateral Net (in thousands) September 30, 2023: Derivatives - VIEs $ 1,911 $ — $ 1,911 $ — $ (621) $ 1,290 December 31, 2022: Derivatives - VIEs $ 7,552 $ — $ 7,552 $ — $ (2,731) $ 4,821 Offsetting of derivative liabilities of consolidated company-sponsored investment funds as of September 30, 2023 and December 31, 2022 was as follows: Gross Amounts of Recognized Liabilities Gross Amounts Offset in the Statement of Financial Condition Net Amounts of Liabilities Presented in the Statement of Financial Condition Financial Cash Collateral Net Amount (in thousands) September 30, 2023: Derivatives - VIEs $ 3,741 $ — $ 3,741 $ — $ (3,337) $ 404 December 31, 2022: Derivatives - VIEs $ 21,540 $ — $ 21,540 $ — $ (5,444) $ 16,096 Cash collateral, whether pledged or received on derivative instruments, is not considered material and, accordingly, is not disclosed by counterparty. Non-Consolidated VIEs As of September 30, 2023, the net assets of company-sponsored investment products that are non-consolidated VIEs are approximately $54.9 billion, and our maximum risk of loss is our investment of $11.0 million in these VIEs and our advisory fee receivables from these VIEs is $99.3 million. As of December 31, 2022, the net assets of company-sponsored investment products that were non-consolidated VIEs was approximately $46.4 billion; our maximum risk of loss was our investment of $5.7 million in these VIEs and our advisory fees receivable from these VIEs was $54.2 million.

Debt Disclosure [Abstract]
Debt	Debt Credit Facility 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 was amended and restated on February 9, 2023, to reflect the transition from US LIBOR, which was retired June 30, 2023, to the term Secured Overnight Financial Rate or "SOFR". Other than this immaterial change, there were no other significant changes included in the amendment. 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 September 30, 2023, 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: SOFR; a Prime rate; or the Federal Funds rate. As of September 30, 2023 and December 31, 2022, we had no amounts outstanding under the Credit Facility. Furthermore, during the first nine months of 2023 and the full year 2022, we did not draw upon the Credit Facility. EQH 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. As of September 30, 2023, we were in compliance with these covenants. 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 both September 30, 2023 and December 31, 2022, AB had $900.0 million outstanding under the EQH Facility, with interest rates of approximately 5.3% and 4.3%, respectively. Average daily borrowings on the EQH Facility for the first nine months of 2023 and the full year 2022 were $778.7 million and $655.2 million, respectively, with weighted average interest rates of approximately 4.8% and 1.7%, respectively. EQH Uncommitted Facility 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 Uncommitted 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 September 30, 2023, we were in compliance with these covenants. As of September 30, 2023, we had no amounts outstanding under the EQH Uncommitted Facility. As of December 31, 2022, we had $90.0 million outstanding under the EQH Uncommitted Facility, with an interest rate of approximately 4.3%. Average daily borrowing on the EQH Uncommitted Facility for the first nine months of 2023 and the full year 2022 were $4.8 million and $0.7 million, respectively, with weighted average interest rates of approximately 4.6% and 4.3%, respectively. Commercial Paper As of September 30, 2023 and December 31, 2022, 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 nine months of 2023 and full year 2022 were $277.1 million and $189.9 million, respectively, with weighted average interest rates of approximately 5.1% and 1.5%, respectively. SCB Lines of Credit SCB LLC currently has five uncommitted lines of credit with five financial institutions. Four of these lines of credit permit us to borrow up to an aggregate of approximately $315.0 million, with AB named as an additional borrower, while the other line has no stated limit. AB has agreed to guarantee the obligations on SCB LLC under these lines of credit. As of September 30, 2023 and December 31, 2022, SCB LLC had no outstanding balance on these lines of credit. Average daily borrowings during the first nine months of 2023 and full year 2022 were $1.5 million and $1.4 million, respectively, with weighted average interest rates of approximately 7.8% and 3.7%, respectively.

Discontinued Operations and Disposal Groups [Abstract]
Divestitures	Divestitures On November 22, 2022, AB and Société Générale (EURONEXT: SCGLY, “SocGen”), a leading European bank, announced plans to form a joint venture combining their respective cash equities and research businesses. Upon closing, AB will own a 49% interest in the joint venture and SocGen will own a 51% interest, with an option to reach 100% ownership after five years. The consummation of the joint venture is subject to customary closing conditions, including regulatory clearances. Due to the expected timing of regulatory approvals, we now expect the closing to occur in the first half of 2024. The assets and liabilities of AB's research services business (“the disposal group”) continue to be classified as held for sale on the condensed consolidated statement of financial condition and recorded at fair value, less cost to sell. As a result of classifying these assets as held for sale, we recognized a non-cash valuation adjustment of $2.1 million and $7.6 million in general and administrative expenses on the condensed consolidated statement of income for the three and nine months ended September 30, 2023, respectively, as well as $7.4 million for the three months ended December 31, 2022, to recognize the net carrying value at lower of cost or fair value, less estimated costs to sell.

Accordingly, we have not classified the disposal group as discontinued operations. The results of operations of the disposal group up to the respective dates of sale will be included in our consolidated results of operations for all periods presented. The lower of amortized cost or fair value adjustment upon transferring these assets to held for sale was not material.

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, 2022 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.
Subsequent Events	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.
