SEMI-ANNUAL REPORT

November 12, 2021

This report provides certain performance data for the AB Multi-Manager Alternative Fund (the “Fund”) for the semi-annual reporting period ended September 30, 2021.

The Fund’s investment objective is to seek long-term capital appreciation.

RETURNS AS OF SEPTEMBER 30, 2021 (unaudited)

	6 Months		12 Months
AB MULTI-MANAGER ALTERNATIVE FUND		2.41%		11.35%
Benchmark: HFRI FOF Composite Index		3.73%		14.41%
MSCI World Index (net)		7.74%		28.82%
Bloomberg US Aggregate Bond Index		1.88%		-0.90%

INVESTMENT RESULTS

The table above provides performance data for the Fund and its benchmark, the HFRI Fund of Funds (“HFRI FOF”) Composite Index, for the six- and 12-month periods ended September 30, 2021. The table also includes the performance of the Morgan Stanley Capital International (“MSCI”) World Index (net) and the Bloomberg US Aggregate Bond Index.

During both periods, the Fund underperformed its benchmark, the HFRI FOF Composite Index, and the MSCI World Index (net), but outperformed the Bloomberg US Aggregate Bond Index.

During the six-month period, underperformance stemmed primarily from the Global Macro Underlying Portfolios allocation, which detracted from relative returns, while also having the largest allocation in the Fund given its diversifying characteristics. The best performing strategies included the Long/Short Equity and Multi-Strategy, while Event Driven only slightly outperformed the benchmark. Global risk assets performed well, supporting the Long/Short Equity and Event Driven strategies, which have a higher propensity to take on idiosyncratic risks across global equity and fixed-income markets. In light of market performance, the underlying portfolios with higher net market exposure outperformed, while the underlying portfolios with lower net exposure also fared well as their long positions outperformed their short positions. Alternatively, Global Macro was positioned for higher interest rates and steeper interest-rate curves, reflecting the view of higher growth and tighter financial conditions as a result. Despite an improving backdrop for economic data, fixed-income markets responded more to technical data and uncertainties about the impact of inflation on future growth, keeping a lid on interest rates and curve spreads. These

abfunds.com AB MULTI-MANAGER ALTERNATIVE FUND    ^|    1

losses were partially offset by continued strength in global commodity markets, with prices boosted by global demand and supply side constraints brought about by supply-chain issues that developed during the economic shutdowns.

For the 12-month period, underperformance relative to the benchmark was again due to the Global Macro allocation, while Long/Short Equity, Multi-Strategy and Event Driven all outperformed the benchmark. The narrative for global macro started in late 2020, with economies around the world reopening following the pandemic shutdowns and the US presidential election outcome bringing expectations for significant fiscal stimulus to stimulate growth. Global Macro Underlying Portfolios initiated short positions in US Treasury bonds and ‘bear steepener’ trades, i.e., a selloff in longer-dated sovereign bonds relative to near-dated bonds, in turn steepening the yield curve. While gains were generated during the first few months of the period, in February 2021, investors began pricing in interest-rate hikes by the US Federal Reserve sooner than previously forecast, leading to notable losses within fixed-income exposures. Alternatively, global equity and corporate credit markets performed well, giving a boost to Long/Short Equity and Event Driven Underlying Portfolios. Multi-Strategy also had a great start to the period, initially from exposure to Special Purpose Acquisition Company-related securities, followed by a strong rally in corporate bonds in the spring.

The Fund utilized total return swaps for hedging and investment purposes, which added to absolute performance for both periods.

MARKET REVIEW AND INVESTMENT STRATEGY

The six-month period ended September 30, 2021 was notably strong for risk assets such as global equities and corporate bonds. This provided a strong boost to both the benchmark index as well as portions of the Fund’s asset allocation, namely Long/Short Equity and Event Driven. The Fund is meant to be a diversifying component of a balanced asset allocation strategy; therefore, the approach of the Fund’s Senior Investment Management Team (the “Team”) is to limit strategies that tend to be more affected by fluctuations in stocks and bonds. That said, the Fund benefited from strong outperformance of Underlying Portfolios in these strategies relative to the Team’s conservative aggregated net market exposure. Global Macro struggled with the volatility in fixed-income assets, particularly in US and European government bonds. The Team was able to reduce the Fund’s exposure to the strategy during the period by reallocating assets to other strategies, and Global Macro Underlying Portfolios still owned by the Fund took down their levels of risk exposure throughout the period. Multi-Strategy had a positive backdrop during the period, with sub-strategies such as convertible bond arbitrage, merger arbitrage and quantitative market neutral all contributing.

2    ^|    AB MULTI-MANAGER ALTERNATIVE FUND abfunds.com

As the period came to a close, global equity markets started to show higher levels of volatility, with September resulting in the largest monthly loss since the pandemic-induced shutdowns started in March 2020. During that period with elevated volatility, all Underlying Portfolios were either flat or positive, leading the Fund to generate a positive return, while also outperforming the benchmark. This reflects the balance across the asset allocation and the limited sensitivity to fluctuations in risk-asset markets on Fund performance outcomes.

INVESTMENT POLICIES

There can be no assurance that the Fund will achieve its investment objective, be able to structure its investments as anticipated, or that its returns will be positive over any period of time. The Fund is not intended as a complete investment program for investors.

The Fund seeks to achieve its investment objective primarily by allocating its assets among investments in a diversified portfolio of private investment vehicles commonly referred to as hedge funds (“Underlying Portfolios”). The Fund will invest primarily in Underlying Portfolios pursuing the following strategies: Long/Short Equity, Event Driven, Credit/Distressed, Global Macro and Multi-Strategy. For more information on these strategies, please see “Consolidated Portfolio of Investments” on pages 8-21. As a secondary strategy, the Fund will generally also make direct investments in securities and other financial instruments. For more information regarding the Fund’s risks, please see “Disclosures and Risks” on pages 4-6 and “Note E—Risks Involved in Investing in the Fund” of the Notes to Consolidated Financial Statements on pages 40-44.

DISCLOSURES AND RISKS

Benchmark Disclosure

All indices are unmanaged and do not reflect fees and expenses associated with the active management of a mutual fund portfolio. The HFRI FOF Composite Index is an equal-weighted performance index that includes over 650 constituent funds of hedge funds that report their monthly net-of-fee returns to Hedge Fund Research, have at least $50 million under management and have been actively trading for at least 12 months. Returns of the Index are subject to subsequent revision. The MSCI World Index (net, free float-adjusted, market capitalization weighted) represents the equity market performance of developed markets. The Bloomberg US Aggregate Bond Index represents the performance of securities within the US investment-grade fixed-rate bond market, with index components for government and corporate securities, mortgage pass-through securities, asset-backed securities and commercial mortgage-backed securities. MSCI makes no express or implied warranties or representations, and shall have no liability whatsoever with respect to any MSCI data contained herein. The MSCI data may not be further redistributed or used as a basis for other indices, any securities or financial products. This report is not approved, reviewed or produced by MSCI. Net returns include the reinvestment of dividends after deduction of non-US withholding tax. An investor cannot invest directly in an index, and its results are not indicative of the performance for any specific investment, including the Fund.

A Word about Risk

An investment in the Fund’s shares involves a high degree of risk and should not constitute a complete investment program. Before making an investment decision, you should carefully consider the following risk factors, together with the other information contained in the prospectus. At any point in time, an investment in the Fund’s shares may be worth less than the original amount invested, even after taking into account the distributions paid, if any, and the ability of shareholders to reinvest distributions. If any of the risks discussed below occurs, the Fund’s results of operations could be materially and adversely affected. If this were to happen, the price of Fund shares could decline significantly and you could lose all or a part of your investment.

Investment in this Fund is highly speculative and involves substantial risk, including loss of principal, and therefore may not be suitable for all investors.

General Risk Factors: Underlying Portfolios and the Fund’s direct investments may exhibit high volatility, and investors may lose all or substantially all of their investment. Investments by Underlying Portfolios and the Fund in illiquid assets and foreign markets and the use of short sales,

4    ^|    AB MULTI-MANAGER ALTERNATIVE FUND abfunds.com

DISCLOSURES AND RISKS (continued)

options, leverage, futures, swaps and other derivative instruments may create special risks and substantially increase the impact and likelihood of adverse price movements. Interests in Underlying Portfolios are subject to limitations on transferability and are illiquid, and no secondary market for interests typically exists or is likely to develop. Underlying Portfolios are typically not registered with securities regulators and are therefore generally subject to little or no regulatory oversight. Performance compensation payable to an Underlying Portfolio investment advisor may create an incentive to make riskier or more speculative investments. Underlying Portfolios typically charge higher fees than many other types of investments, which can offset trading profits, if any. There can be no assurance that any Underlying Portfolio will achieve its investment objectives.

Market Risk: The value of the Fund’s assets will fluctuate as the bond or stock market fluctuates. The value of its investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events, including public health crises (including the occurrence of a contagious disease or illness), that affect large portions of the market.

Tax Risks: The Fund intends to be treated as a regulated investment company (“RIC”) under the Internal Revenue Code. However, in order to qualify as a RIC and also to avoid having to pay an “excise tax,” the Fund will be subject to certain limitations on its investments and operations, including a requirement that a specified proportion of its income come from qualifying sources, an asset diversification requirement and minimum distribution requirements. Satisfaction of the various requirements requires significant support and information from the Underlying Portfolios, and such support and information may not be available, sufficient, verifiable, or provided on a timely basis.

Limited Liquidity: The Fund’s shares are not listed on any securities exchange or traded in any other market, and are subject to substantial restrictions on transfer. Although the Fund has offered to repurchase shares on a quarterly basis, such periodic repurchase offers are at the sole discretion of the Fund’s Board of Trustees, and there is no assurance that these repurchase offers will continue. It will normally be four to six months between the time an investor tenders shares for repurchase (i.e., requests that the Fund repurchase shares as part of a repurchase offer) and the investor’s receipt of any cash proceeds associated with the repurchase.

Fund of Funds Considerations: The Fund will have no control rights over and limited transparency into the investment programs of the Underlying Portfolios in which it invests. In valuing the Fund’s holdings, the Investment Manager will generally rely on financial information provided by Underlying Portfolios, which may be unaudited, estimated and/or may not involve third parties. The Fund’s investment opportunities may be limited

DISCLOSURES AND RISKS (continued)

as a result of withdrawal terms or anticipated liquidity needs (e.g., withdrawal restrictions imposed by underlying hedge funds may delay, preclude or involve expense in connection with portfolio adjustments by the Investment Manager).

These risks are fully discussed in the Fund’s prospectus. As with all investments, you may lose money by investing in the Fund.

* The investment strategies and liquidity of the Underlying Portfolios in which the Fund invests are as follows:

Global Macro Underlying Portfolios aim to identify and exploit imbalances in global economics and asset classes, typically utilizing macroeconomic and technical market factors rather than “bottom-up” individual security analysis. The Underlying Portfolios within this strategy are subject to 3 – 90 day redemption notice periods. The majority of the Underlying Portfolios are no longer subject to initial lockups. Certain Underlying Portfolios have lock up periods of up to one year.

Long/Short Equity Underlying Portfolios seek to buy securities with the expectation that they will increase in value (“going long”) and sell securities short in the expectation that they will decrease in value (“going short”). Underlying Portfolios within this strategy are generally subject to 45 – 120 day redemption notice periods. The majority of the Underlying Portfolios are no longer subject to initial lockups. Certain Underlying Portfolios have lock up periods of up to three years.

abfunds.com AB MULTI-MANAGER ALTERNATIVE FUND    ^|    17

CONSOLIDATED PORTFOLIO OF INVESTMENTS (continued)

Multi-Strategy Underlying Portfolios invest across multiple strategies, including long/short equity, event driven, global macro, credit/distressed and emerging markets, in which the investment process is predicated on movements in underlying economic variables and the impact these variables have on equity, fixed income, currency, commodity and other financial instrument markets. Underlying Portfolios within this strategy are generally subject to 45 – 90 day redemption notice periods. Certain Underlying Portfolios may have lock up periods of two years.

Event Driven Underlying Portfolios seek to take advantage of information inefficiencies resulting from a particular corporate event, such as a takeover, liquidation, bankruptcy, tender offer, buyback, spin off, exchange offer, merger or other type of corporate reorganization. Underlying Portfolios within this strategy are generally subject to 60 – 90 day redemption notice periods. The majority of the Underlying Portfolios are no longer subject to initial lockups. Certain Underlying Portfolios have lock up periods of up to one year.

Credit/Distressed Underlying Portfolios invest in a variety of fixed income and other securities, including bonds (corporate and government), bank debt, asset-backed financial instruments, mortgage-backed securities and mezzanine and distressed securities, as well as securities of distressed companies and high yield securities. Underlying Portfolios within this strategy are generally subject to 90 day redemption notice periods. The majority of the Underlying Portfolios are no longer subject to initial lockups.

The Fund may also make direct investments in securities (other than securities of Underlying Portfolios), options, futures, options on futures, swap contracts, or other derivative or financial instruments.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE A

Significant Accounting Policies

AB Multi-Manager Alternative Fund (the “Fund”) is a statutory trust formed under the laws of the State of Delaware and registered under the Investment Company Act of 1940 as a diversified, closed-end management investment company. The Fund commenced operations on October 1, 2012. The Fund’s investment objective is to seek long-term capital appreciation. There can be no assurance that the Fund will achieve its investment objective, be able to structure its investments as anticipated, or that its returns will be positive over any period of time. The Fund is not intended as a complete investment program for investors. The Fund seeks to achieve its investment objective primarily by allocating its assets among investments in private investment vehicles (“Underlying Portfolios”), commonly referred to as hedge funds, that are managed by unaffiliated asset managers that employ a broad range of investment strategies. As a secondary strategy, the Fund will generally also make direct investments in securities and other financial instruments. As part of the Fund’s investment strategy, the Fund seeks exposure to commodities and commodities-related instruments and derivatives primarily through investments in AB Multi-Manager Alternative Fund (Cayman), Ltd., a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands (the “Subsidiary”). The Subsidiary commenced operations on September 21, 2018. The Fund is the sole shareholder of the Subsidiary and it is intended that the Fund will remain the sole shareholder and will continue to control the Subsidiary. Under the Articles of Association of the Subsidiary, shares issued by the Subsidiary confer upon a shareholder the right to receive notice of, to attend and to vote at general meetings of the Subsidiary and shall confer upon the shareholder rights in a winding-up or repayment of capital and the right to participate in the profits or assets of the Subsidiary. As of September 30, 2021, net assets of the Fund were $1,062,322,552, of which $9,207,286, or approximately 1%, represented the Fund’s ownership of all issued shares and voting rights of the Subsidiary. This report presents the consolidated financial statements of the Fund and the Subsidiary. All intercompany transactions and balances have been eliminated in consolidation. The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”), which require management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities in the consolidated financial statements and amounts of income and expenses during the reporting period. Actual results could differ from those estimates. The Fund is an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies. The following is a summary of significant accounting policies followed by the Fund.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

1. Valuation of Investments

The Fund’s Board of Trustees (the “Board”) has approved pricing and valuation policies and procedures pursuant to which the Fund’s investments in Underlying Portfolios are valued at fair value (the “Valuation Procedures”). Among other matters, the Valuation Procedures set forth the Fund’s valuation policies and the mechanisms and processes to be employed on a monthly basis to implement such policies. In accordance with the Valuation Procedures, fair value of an Underlying Portfolio as of each valuation time ordinarily is the value determined as of such month-end for each Underlying Portfolio in accordance with the Underlying Portfolio’s valuation policies and reported at the time of the Fund’s valuation.

On a monthly basis, the Fund generally uses the net asset value (“NAV”), provided by the Underlying Portfolios, to determine the fair value of all Underlying Portfolios which (a) do not have readily determinable fair values and (b) either have the attributes of an investment company or prepare their financial statements consistent with measurement principles of an investment company. As a general matter, the fair value of the Fund’s interest in an Underlying Portfolio represents the amount that the Fund could reasonably expect to receive from an Underlying Portfolio if its interest were redeemed at the time of valuation. In the unlikely event that an Underlying Portfolio does not report a month-end value to the Fund on a timely basis, the Fund would determine the fair value of such Underlying Portfolio based on the most recent value reported by the Underlying Portfolio, and any other relevant information available at the time the Fund values its portfolio. In making a fair value determination, the Fund will consider all appropriate information reasonably available to it at the time and that AllianceBernstein L.P. (the “Investment Manager”) believes to be reliable. The Fund may consider factors such as, among others: (i) the price at which recent subscriptions for or redemptions of the Underlying Portfolio’s interests were effected; (ii) information provided to the Fund by the manager of an Underlying Portfolio, or the failure to provide such information as the Underlying Portfolio manager agreed to provide in the Underlying Portfolio’s offering materials or other agreements with the Fund; (iii) relevant news and other sources; and (iv) market events. In addition, when an Underlying Portfolio imposes extraordinary restrictions on redemptions, or when there have been no recent subscriptions for Underlying Portfolio interests, the Fund may determine that it is appropriate to apply a discount to the NAV reported by the Underlying Portfolio. The use of different factors and estimation methodologies could have a significant effect on the estimated fair value and could be material to the consolidated financial statements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

The Investment Manager has established a Valuation Committee (the “Committee”) made up of representatives of portfolio management, fund accounting, compliance and risk management which operates under the Valuation Procedures and is responsible for overseeing the pricing and valuation of all securities held in the Fund. The Committee’s responsibilities include: 1) fair value determinations (and oversight of any third parties to whom any responsibility for fair value determinations is delegated), and 2) regular monitoring of the Valuation Procedures and modification or enhancement of the Valuation Procedures (or recommendation of the modification of the Valuation Procedures) as the Committee believes appropriate. Prior to investing in any Underlying Portfolio, and periodically thereafter, the Investment Manager will conduct a due diligence review of the valuation methodology utilized by the Underlying Portfolio. In addition, there are several processes outside of the pricing process that are used to monitor valuation issues including: 1) performance and performance attribution reports are monitored for anomalous impacts based upon benchmark performance, and 2) portfolio managers review all portfolios for performance and analytics.

Portfolio securities are valued at their current market value determined on the basis of market quotations or, if market quotations are not readily available or are deemed unreliable, at “fair value” as determined in accordance with procedures established by and under the general supervision of the Board.

In general, the market values of securities which are readily available and deemed reliable are determined as follows: securities listed on a national securities exchange (other than securities listed on the NASDAQ Stock Market, Inc. (“NASDAQ”)) or on a foreign securities exchange are valued at the last sale price at the close of the exchange or foreign securities exchange. If there has been no sale on such day, the securities are valued at the last traded price from the previous day. Securities listed on more than one exchange are valued by reference to the principal exchange on which the securities are traded; securities listed only on NASDAQ are valued in accordance with the NASDAQ Official Closing Price; listed or over the counter (“OTC”) market put or call options are valued at the mid level between the current bid and ask prices. If either a current bid or current ask price is unavailable, the Investment Manager will have discretion to determine the best valuation (e.g., last trade price in the case of listed options); open futures are valued using the closing settlement price or, in the absence of such a price, the most recent quoted bid price. If there are no quotations available for the day of valuation, the last available closing settlement price is used; U.S. Government securities and any other debt instruments having 60 days or less remaining until maturity are generally valued at market by an independent pricing vendor, if a market price is

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

available. If a market price is not available, the securities are valued at amortized cost. This methodology is commonly used for short term securities that have an original maturity of 60 days or less, as well as short term securities that had an original term to maturity that exceeded 60 days. In instances when amortized cost is utilized, the Committee must reasonably conclude that the utilization of amortized cost is approximately the same as the fair value of the security. Factors the Committee will consider include, but are not limited to, an impairment of the creditworthiness of the issuer or material changes in interest rates. Fixed-income securities, including mortgage-backed and asset-backed securities, may be valued on the basis of prices provided by a pricing service or at a price obtained from one or more of the major broker-dealers. In cases where broker-dealer quotes are obtained, the Investment Manager may establish procedures whereby changes in market yields or spreads are used to adjust, on a daily basis, a recently obtained quoted price on a security. Swaps and other derivatives are valued daily, primarily using independent pricing services, independent pricing models using market inputs, as well as third party broker-dealers or counterparties. Open-end mutual funds are valued at the closing net asset value per share, while exchange traded funds are valued at the closing market price per share.

Securities for which market quotations are not readily available (including restricted securities) or are deemed unreliable are valued at fair value as deemed appropriate by the Investment Manager. Factors considered in making this determination may include, but are not limited to, information obtained by contacting the issuer, analysts, analysis of the issuer’s financial statements or other available documents. In addition, the Fund may use fair value pricing for securities primarily traded in non-U.S. markets because most foreign markets close well before the Fund values its securities at 4:00 p.m., Eastern Time. The earlier close of these foreign markets gives rise to the possibility that significant events, including broad market moves, may have occurred in the interim and may materially affect the value of those securities. To account for this, the Fund generally values many of its foreign equity securities using fair value prices based on third party vendor modeling tools to the extent available.

U.S. GAAP establishes a framework for measuring fair value, and a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability. Inputs may be observable or unobservable and refer broadly to the assumptions that market participants would use in pricing the asset or liability. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Fund. Unobservable inputs reflect the Fund’s own assumptions about the assumptions that market participants would use in pricing the asset or

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

liability based on the best information available in the circumstances. Each investment is assigned a level based upon the observability of the inputs which are significant to the overall valuation. The three-tier hierarchy of inputs is summarized below.

• Level 1—quoted prices in active markets for identical investments

• Level 2—other significant observable inputs

• Level 3—significant unobservable inputs

The fair value of debt instruments, such as bonds, and over-the-counter derivatives is generally based on market price quotations, recently executed market transactions (where observable) or industry recognized modeling techniques and are generally classified as Level 2. Pricing vendor inputs to Level 2 valuations may include quoted prices for similar investments in active markets, interest rate curves, coupon rates, currency rates, yield curves, option adjusted spreads, default rates, credit spreads and other unique security features in order to estimate the relevant cash flows which is then discounted to calculate fair values. If these inputs are unobservable and significant to the fair value, these investments will be classified as Level 3.

Where readily available market prices or relevant bid prices are not available for certain equity investments, such investments may be valued based on similar publicly traded investments, movements in relevant indices since last available prices or based upon underlying company fundamentals and comparable company data (such as multiples to earnings or other multiples to equity). Where an investment is valued using an observable input, such as another publicly traded security, the investment will be classified as Level 2. If management determines that an adjustment is appropriate based on restrictions on resale, illiquidity or uncertainty, and such adjustment is a significant component of the valuation, the investment will be classified as Level 3. An investment will also be classified as Level 3 where management uses company fundamentals and other significant inputs to determine the valuation.

Valuations reflected in this report are as of the report date. As a result, changes in valuation due to market events and/or issuer related events after the report date and prior to issuance of the report are not reflected herein.

2. Cash Committed

As of September 30, 2021, the Fund has committed to purchase the following Underlying Portfolios for effective date October 1, 2021:

Underlying Portfolios	Amount Committed
Schonfeld Strategic Partners Offshore Fund LTD.*	$	2,000,000
Elliott International Limited — Capital Commitment*		5,000,000

* Investments paid in advance amounted to $7,000,000.

3. Currency Translation

Assets and liabilities denominated in foreign currencies and commitments under forward currency exchange contracts are translated into U.S. dollars at the mean of the quoted bid and ask prices of such currencies against the U.S. dollar. Purchases and sales of portfolio securities are translated into U.S. dollars at the rates of exchange prevailing when such securities were acquired or sold. Income and expenses are translated into U.S. dollars at rates of exchange prevailing when accrued.

Net realized gain or loss on foreign currency transactions represents foreign exchange gains and losses from sales and maturities of foreign fixed income investments, holding of foreign currencies, currency gains or losses realized between the trade and settlement dates on foreign investment transactions, and the difference between the amounts of dividends, interest and foreign withholding taxes recorded on the Fund’s books and

abfunds.com AB MULTI-MANAGER ALTERNATIVE FUND    ^|    31

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

the U.S. dollar equivalent amounts actually received or paid. Net unrealized currency gains and losses from valuing foreign currency denominated assets and liabilities at period end exchange rates are reflected as a component of net unrealized appreciation or depreciation of foreign currency denominated assets and liabilities.

4. Taxes

It is the Fund’s policy to meet the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its investment company taxable income and net realized gains, if any, to shareholders. Therefore, no provisions for federal income or excise taxes are required. The Fund intends to continue to comply with the requirements of Subchapter M of the Internal Revenue Code of 1986 as they apply to regulated investment companies. By so complying, the Fund will not be subject to federal and state income taxes to the extent that all of its income is distributed.

For federal tax purposes, taxable income for the Fund and its Subsidiary are calculated separately. The Subsidiary is classified as a controlled foreign corporation (“CFC”) under the Code and its taxable income is included in the calculation of the Fund’s taxable income. Net losses of the Subsidiary are not deductible by the Fund either in the current period or future periods. The CFC has a taxable fiscal year end of March 31st.

In accordance with U.S. GAAP requirements regarding accounting for uncertainties in income taxes, management has analyzed the Fund’s tax positions taken or expected to be taken on federal and state income tax returns for all open tax years (the current and the prior three tax years) and has concluded that no provision for income tax is required in the Fund’s consolidated financial statements.

5. Investment Income and Investment Transactions

Income and capital gain distributions, if any, are recorded on the ex-dividend date. Investment transactions are accounted for on the trade date or effective date. Investment gains and losses are determined on the identified cost basis. The Fund accounts for distributions received from REIT investments or from regulated investment companies as dividend income, realized gain, or return of capital based on information provided by the REIT or the investment company.

6. Expenses

Expenses included in the accompanying consolidated statement of operations do not include any expenses of the Underlying Portfolios.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

7. Dividends and Distributions

Dividends and distributions to shareholders, if any, are recorded on the ex-dividend date. Income dividends and capital gains distributions are determined in accordance with federal tax regulations and may differ from those determined in accordance with U.S. GAAP. To the extent these differences are permanent, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require such reclassification.

NOTE B

Management Fee and Other Transactions with Affiliates

Under the terms of the investment advisory agreement, the Fund pays the Investment Manager a management fee at an annual rate of 1.00% of an aggregate of the Fund’s net assets determined as of the last day of a calendar month and adjusted for subscriptions and repurchases accepted as of the first day of the subsequent month (the “Management Fee”). The Management Fee is payable in arrears as of the last day of the subsequent month.

Under a separate Administrative Reimbursement Agreement, the Fund may use the Investment Manager and its personnel to provide certain administrative services to the Fund and, in such event, the services and payments will be subject to approval by the Fund’s Board. For the six months ended September 30, 2021, the reimbursement for such fees amounted to $139,264.

The Fund may engage one or more distributors to solicit investments in the Fund. Sanford C. Bernstein & Company LLC (“Bernstein”) and AllianceBernstein Investments, Inc. (“ABI”), each an affiliate of the Investment Manager, have been selected as distributors of the Fund under Distribution Services Agreements. The Distribution Services Agreements do not call for any payments to be made to Bernstein or ABI by the Fund.

The Fund compensates AllianceBernstein Investor Services, Inc. (“ABIS”), a wholly-owned subsidiary of the Investment Manager, under a Transfer Agency Agreement for providing personnel and facilities to perform transfer agency services for the Fund. Such compensation paid to ABIS amounted to $106,634 for the six months ended September 30, 2021.

The Fund may invest in AB Government Money Market Portfolio (the “Government Money Market Portfolio”) which has a contractual annual advisory fee rate of .20% of the portfolio’s average daily net assets and bears its own expenses. The Investment Manager has contractually agreed to waive .10% of the advisory fee of Government Money Market Portfolio (resulting in a net advisory fee of .10%) until August 31, 2022. In

abfunds.com AB MULTI-MANAGER ALTERNATIVE FUND    ^|    33

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

connection with the investment by the Fund in Government Money Market Portfolio, the Investment Manager has contractually agreed to waive its advisory fee from the Fund in an amount equal to the Fund’s pro rata share of the effective advisory fee of Government Money Market Portfolio, as borne indirectly by the Fund as an acquired fund fee and expense. For the six months ended September 30, 2021, such waiver amounted to $12,150.

A summary of the Fund’s transactions in AB mutual funds for the six months ended September 30, 2021 is as follows:

Fund	Market Value 3/31/21 (000)		Purchases at Cost (000)		Sales Proceeds (000)		Market Value 9/30/21 (000)		Dividend Income (000)

Net unrealized appreciation	$	246,100,498

2. Derivative Financial Instruments

The Fund may use derivatives in an effort to earn income and enhance returns, to replace more traditional direct investments, to obtain exposure to otherwise inaccessible markets (collectively, “investment purposes”), or to hedge or adjust the risk profile of its portfolio.

34    ^|    AB MULTI-MANAGER ALTERNATIVE FUND abfunds.com

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

The principal type of derivative utilized by the Fund, as well as the methods in which they may be used are:

• Swaps

The Fund may enter into swaps to hedge its exposure to interest rates, credit risk, equity markets or currencies. The Fund may also enter into swaps for non-hedging purposes as a means of gaining market exposures, making direct investments in foreign currencies, as described below under “Currency Transactions” or in order to take a “long” or “short” position with respect to an underlying referenced asset described below under “Total Return Swaps”. A swap is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a specified amount of an underlying asset. The payment flows are usually netted against each other, with the difference being paid by one party to the other. In addition, collateral may be pledged or received by the Fund in accordance with the terms of the respective swaps to provide value and recourse to the Fund or its counterparties in the event of default, bankruptcy or insolvency by one of the parties to the swap.

Risks may arise as a result of the failure of the counterparty to the swap to comply with the terms of the swap. The loss incurred by the failure of a counterparty is generally limited to the net interim payment to be received by the Fund, and/or the termination value at the end of the contract. Therefore, the Fund considers the creditworthiness of each counterparty to a swap in evaluating potential counterparty risk. This risk is mitigated by having a netting arrangement between the Fund and the counterparty and by the posting of collateral by the counterparty to the Fund to cover the Fund’s exposure to the counterparty. Additionally, risks may arise from unanticipated movements in interest rates or in the value of the underlying securities. The Fund accrues for the interim payments on swaps on a daily basis, with the net amount recorded within unrealized appreciation/depreciation of swaps on the consolidated statement of assets and liabilities, where applicable. Once the interim payments are settled in cash, the net amount is recorded as realized gain/(loss) on swaps on the consolidated statement of operations, in addition to any realized gain/(loss) recorded upon the termination of swaps. Upfront premiums paid or received for swaps are recognized as cost or proceeds on the consolidated statement of assets and liabilities and are amortized on a straight line basis over the life of the contract. Amortized upfront premiums are included in net realized gain/(loss) from swaps on the consolidated statement of operations. Fluctuations in the value of swaps are recorded as a component of

abfunds.com AB MULTI-MANAGER ALTERNATIVE FUND    ^|    35

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

net change in unrealized appreciation/depreciation of swaps on the consolidated statement of operations.

Total Return Swaps:

The Fund may enter into total return swaps in order to take a “long” or “short” position with respect to an underlying referenced asset. The Fund is subject to market price volatility of the underlying referenced asset. A total return swap involves commitments to pay interest in exchange for a market linked return based on a notional amount. To the extent that the total return of the security, group of securities or index underlying the transaction exceeds or falls short of the offsetting interest obligation, the Fund will receive a payment from or make a payment to the counterparty.

During the six months ended September 30, 2021, the Fund held total return swaps for hedging and non-hedging purposes.

The Fund and the Subsidiary typically enter into International Swaps and Derivatives Association, Inc. Master Agreements (“ISDA Master Agreement”) with their OTC derivative contract counterparties in order to, among other things, reduce their credit risk to OTC counterparties. ISDA Master Agreements include provisions for general obligations, representations, collateral and events of default or termination. Under an ISDA Master Agreement, the Fund and the Subsidiary typically may offset with the OTC counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment (close-out netting) in the event of default or termination. In the event of a default by an OTC counterparty, the return of collateral with market value in excess of the Fund’s and the Subsidiary’s net liability, held by the defaulting party, may be delayed or denied.

The Fund’s and Subsidiary’s ISDA Master Agreements may contain provisions for early termination of OTC derivative transactions in the event the net assets of the Fund or the Subsidiary decline below specific levels (“net asset contingent features”). If these levels are triggered, the Fund’s and the Subsidiary’s OTC counterparty has the right to terminate such transaction and require the Fund or the Subsidiary to pay or receive a settlement amount in connection with the terminated transaction. For additional details, please refer to netting arrangements by the OTC counterparty tables below.

3. Currency Transactions

The Fund may invest in non-U.S. Dollar-denominated securities on a currency hedged or unhedged basis through its investments in an Underlying Portfolio. The Fund or an Underlying Portfolio may seek investment opportunities by taking long or short positions in currencies through the use of currency-related derivatives, including forward currency exchange contracts, futures and options on futures, swaps, and other options. The Fund or an Underlying Portfolio may enter into transactions for investment opportunities when it anticipates that a foreign currency will appreciate or depreciate in value but securities denominated in that currency are not held by the Fund or the Underlying Portfolio and do not present attractive investment opportunities. Such transactions may also be used when the Investment Manager or the manager of an Underlying Portfolio believes that it may be more efficient than a direct investment in a foreign currency-denominated security. The Fund or an Underlying Portfolio may also conduct currency exchange contracts on a spot basis (i.e., for cash at the spot rate prevailing in the currency exchange market for buying or selling currencies).

NOTE D

Shares of Beneficial Interest

Generally, initial and additional subscriptions for shares may be accepted as of the first day of each month. The Fund reserves the right to reject any subscription for shares. The Fund intends to repurchase shares from shareholders in accordance with written tenders by shareholders at those times, in those amounts, and on such terms and conditions as the Board may determine in its sole discretion. When a repurchase offer occurs, a shareholder will generally be required to provide notice of their tender of shares for repurchase to the Fund more than three months in advance of the date that the shares will be valued for repurchase (the “Valuation Date”). Valuation Dates are generally expected to be the last business days of March, June, September or December, and payment for tendered

abfunds.com AB MULTI-MANAGER ALTERNATIVE FUND    ^|    39

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

shares will generally be made by the Fund approximately 45 days following the Valuation Date. If 95% or more of a shareholder’s shares are repurchased, the shareholder will receive an initial payment equal to 95% of the value of the shares and the balance due will be paid promptly after completion of the next audit of the Fund’s financial statements.

Transactions in shares of beneficial interest were as follows for the six months ended September 30, 2021 and the year ended March 31, 2021:

NOTE E

Risks Involved in Investing in the Fund

The market value of a security held by the Fund or an Underlying Portfolio may move up or down, sometimes rapidly and unpredictably. These fluctuations may cause a security to be worth less than the price originally paid for it, or less than it was worth at an earlier time. Market risk may affect a single issuer, industry, sector of the economy or the market as a whole. Global economies and financial markets are increasingly interconnected, which increases the probabilities that conditions in one country or region might adversely impact issuers in a different country or region. Conditions affecting the general economy, including political, social, or economic instability at the local, regional, or global level may also affect the market value of a security. Health crises, such as pandemic and epidemic diseases, as well as other incidents that interrupt the expected course of events, such as natural disasters, war or civil disturbance, acts of terrorism, power outages and other unforeseeable and external events, and the public response to or fear of such diseases or events, have and may in the future have an adverse effect on the Fund’s investments and net asset value and can lead to increased market volatility. For example, any preventative or protective actions that governments may take in respect of such diseases or events may result in periods of business disruption, inability to obtain raw materials, supplies and component parts, and reduced or disrupted operations for the Fund’s portfolio companies. The occurrence and pendency of such diseases or events could adversely affect the economies and financial markets either in specific countries or worldwide.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

Limitations on the Fund’s ability to withdraw its assets from Underlying Portfolios may limit the Fund’s ability to repurchase its shares. For example, many Underlying Portfolios impose lock-up periods prior to allowing withdrawals, which can be two years or longer. After expiration of the lock-up period, withdrawals typically are permitted only on a limited basis, such as monthly, quarterly, semi-annually or annually. Many Underlying Portfolios may also indefinitely suspend redemptions or establish restrictions on the ability to fully receive proceeds from redemptions through the application of a redemption restriction or “gate”. In instances where the primary source of funds to repurchase shares will be withdrawals from Underlying Portfolios, the application of these lock-ups and withdrawal limitations may significantly limit the Fund’s ability to repurchase its shares. Although the Investment Manager will seek to select Underlying Portfolios that offer the opportunity to have their shares or units redeemed within a reasonable timeframe, there can be no assurance that the liquidity of the investments of such Underlying Portfolios will always be sufficient to meet redemption requests as, and when, made.

The Fund invests primarily in Underlying Portfolios that are not registered under the 1940 Act and invest in and actively trade securities and other financial instruments using different strategies and investment techniques that may involve significant risks. As a secondary strategy, the Fund will also generally make direct investments in securities and other financial instruments. The risks associated with these investments include those related to the volatility of the equity, credit, and currency markets, the use of leverage associated with certain investment strategies, derivative contracts and in connection with short positions, the potential illiquidity of certain instruments and counterparty and broker arrangements.

Some of the Underlying Portfolios in which the Fund invests may invest all or a portion of their assets in securities that are illiquid or are subject to an anticipated event. These Underlying Portfolios may create “side pockets” in which to hold these securities. Side pockets are series or classes of shares which are not redeemable by the investors but which are automatically redeemed or converted back into the Underlying Portfolio’s regular series or classes of shares upon the realization of those securities or the happening of some other liquidity event with respect to those securities.

These “side pockets” can often be held for long periods before they are realized, and may therefore be much less liquid than the general liquidity offered on the Underlying Portfolio’s regular series or classes of shares. Should the Fund seek to liquidate its investment in an Underlying Portfolio that maintains investments in a side pocket arrangement or that holds a substantial portion of its assets in illiquid securities, the Fund might not be able to fully liquidate its investments without delay, which could be considerable. In such cases,

abfunds.com AB MULTI-MANAGER ALTERNATIVE FUND    ^|    41

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

during the period until the Fund is permitted to fully liquidate the investment in the Underlying Portfolio, the value of the investment could fluctuate.

The Underlying Portfolios generally utilize leverage in pursuit of achieving a potentially greater investment return and the Fund may take on additional leverage in connection with its direct investment strategies. The use of leverage exposes an Underlying Portfolio and the Fund to additional risk including (i) greater losses from investments than would otherwise have been the case had the leverage not been used; (ii) margin calls or interim margin requirements may force premature liquidations of investment positions; and (iii) losses on investments where the investment fails to earn a return that equals or exceeds the cost of leverage related to such investment. In the event of a sudden, precipitous drop in the value of an Underlying Portfolio’s assets, the Underlying Portfolio might not be able to liquidate assets quickly enough to repay its borrowings, further magnifying the losses incurred by the Underlying Portfolio.

The Underlying Portfolios or the Fund may invest in securities of foreign companies that involve special risks and considerations not typically associated with investments in the United States. Such investments may be concentrated in a limited number of countries or regions, which may vary over time. Such investments may subject the Underlying Portfolios and the Fund to additional risks resulting from political or economic conditions in such countries or regions, and the possible imposition of adverse governmental laws or currency exchange restrictions could cause the securities and their markets to be less liquid and their prices to be more volatile than those of comparable U.S. securities.

There is the risk that changes in foreign currency exchange rates may negatively affect the value of the Fund’s or the Underlying Portfolios’ investments and reduce the returns of the Fund. For example, the value of the Fund’s or an Underlying Portfolio’s investments in foreign currency-denominated securities may decrease if the U.S. dollar is strong (i.e., gaining value relative to other currencies) and other currencies are weak (i.e., losing value relative to the U.S. dollar). Currency markets are generally not as regulated as securities markets. Independent of the Fund’s or an Underlying Portfolio’s investments denominated in foreign currencies, positions in foreign currencies themselves may cause the Fund or an Underlying Portfolio to experience investment losses due to the changes in exchange rates and interest rates.

The Underlying Portfolios may invest a higher percentage of their assets in specific sectors of the market in order to achieve a potentially greater investment return. As a result, the Underlying Portfolios may be more susceptible to economic, political and regulatory developments in a particular sector of the market, positive or negative, and may experience increased volatility of the Underlying Portfolio’s net asset value.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

The Fund invests in a limited number of Underlying Portfolios. Such concentration may result in additional risk. Various risks are also associated with an investment in the Fund, including risks relating to compensation arrangements and risks relating to limited liquidity of the interests.

The Fund and the Underlying Portfolios may enter into derivative transactions such as forwards, options, futures and swaps. Derivatives may be illiquid, difficult to price, and leveraged so that small changes may produce disproportionate losses, and subject to counterparty risk to a greater degree than more traditional investments. Derivatives may result in significant losses, including losses that are far greater than the value of the derivatives reflected in the consolidated statement of assets and liabilities.

The Fund is subject to credit risk arising from its transactions with its custodian, State Street Bank and Trust, related to holding the Fund’s cash. This credit risk arises to the extent that the custodian may be unable to fulfill its obligation to return the Fund’s cash held in its custody.

A Fund or Underlying Portfolio may invest in debt securities, derivatives or other financial instruments that utilize the London Interbank Offered Rate, or “LIBOR,” as a “benchmark” or “reference rate” for various interest rate calculations. The United Kingdom Financial Conduct Authority, which regulates LIBOR, will cease publishing certain LIBOR benchmarks at the end of 2021. Although certain LIBOR rates are intended to be published until June 2023, banks are strongly encouraged to cease entering into agreements with counterparties referencing LIBOR by the end of 2021. Although financial regulators and industry working groups have suggested alternative reference rates, such as the European Interbank Offer Rate, the Sterling Overnight Interbank Average Rate and the Secured Overnight Financing Rate, global consensus on alternative rates is lacking and the process for amending existing contracts or instruments to transition away from LIBOR is underway but remains incomplete. The elimination of LIBOR or changes to other reference rates or any other changes or reforms to the determination or supervision of reference rates could have an adverse impact on the market for, or value of, any securities or payments linked to those reference rates, which may adversely affect a Fund’s performance and/or net asset value. Uncertainty and risk also remain regarding the willingness and ability of issuers and lenders to include revised provisions in new and existing contracts or instruments. Consequently, the transition away from LIBOR to other reference rates may lead to increased volatility and illiquidity in markets that are tied to LIBOR, fluctuations in values of LIBOR-related investments or investments in issuers that utilize LIBOR, increased difficulty in borrowing or refinancing and diminished effectiveness of hedging strategies, potentially adversely affecting a Fund’s performance. Furthermore, the risks associated with the expected discontinuation of LIBOR and

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

transition may be exacerbated if the work necessary to effect an orderly transition to an alternative reference rate is not completed in a timely manner. Because the usefulness of LIBOR as a benchmark could deteriorate during the transition period, these effects could occur prior to the end of 2021.

In the ordinary course of business, the Fund enters into contracts that contain a variety of indemnifications. The Fund’s maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these indemnification provisions and expects the risk of loss thereunder to be remote. Therefore, the Fund has not accrued any liability in connection with these indemnification provisions.

Tax Information

The tax character of fiscal year-end distributions for 2021 is based on estimated tax information provided by certain Underlying Portfolios. The character may materially change as the Fund receives final 2020 tax reporting from Underlying Portfolios. The tax character of distributions paid during the fiscal years ended March 31, 2021 and March 31, 2020 were as follows:

	2021		2020
Distributions paid from:
Ordinary income	$	51,824,593	$	5,010,584
Long-term capital gains		8,682,346		14,167,557
Total taxable distributions paid	$	60,506,939	$	19,178,141

As of March 31, 2021, the components of accumulated earnings/(deficit) on a tax basis were as follows:

Undistributed ordinary income	$	14,547,240
Accumulated capital and other losses		2,703,761
Unrealized appreciation/(depreciation)		77,270,939	(a)
Total accumulated earnings/(deficit)	$	94,521,940

(a) The differences between book-basis and tax-basis unrealized appreciation/(depreciation) are attributable primarily to the tax treatment of passive foreign investment companies (PFICs) and the tax treatment of swaps.

For tax purposes, net realized capital losses may be carried over to offset future capital gains, if any. Funds are permitted to carry forward capital losses for an indefinite period, and such losses will retain their character as either short-term or long-term capital losses. As of March 31, 2021, the Fund did not have any capital loss carryforwards.

Credit Facility

The Fund is a party to a revolving credit facility (the “Facility”) intended to provide short term financing, if necessary, subject to certain restrictions in connection with, among other matters, abnormal redemption activity. Borrowings under the Facility are secured by the assets of the Fund. Credit Facility fees are paid by the Fund and are included in the consolidated statement of operations. The Fund did not utilize the Facility during the six months ended September 30, 2021. Prior to October 23, 2020, the Facility’s credit limit was $50 million and was $25 million thereafter through September 30, 2021.

Recent Accounting Pronouncements

In March 2020, the Financial Accounting Standards Board issued an Accounting Standards Update, ASU 2020-04, “Reference Rate Reform (Topic 848) – Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” ASU 2020-04 provides optional guidance to ease the potential accounting burden due to the discontinuation of the LIBOR and other interbank-offered based reference rates. ASU 2020-04 is effective as of March 12, 2020 through December 31, 2022. Management is currently evaluating the impact, if any, of applying ASU 2020-04.

NOTE I

Subsequent Events

Management has evaluated subsequent events for possible recognition or disclosure in the consolidated financial statements through the date the consolidated financial statements are issued. Management has determined that there are no material events that would require disclosure in the Fund’s consolidated financial statements through this date.

Information Regarding the Review and Approval of the Fund’s Advisory Agreement

AB Multi-Manager Alternative Fund (the “Fund”) is subject to Section 15 of the Investment Company Act of 1940, as amended. Section 15 provides that any investment advisory agreement with a registered investment company such as the Fund may continue in effect for a period of more than two years from the date of its execution, only so long as such continuance is specifically approved at least annually by the board of trustees (or by vote of a majority of the outstanding voting securities of the investment company). Pursuant to this requirement, the Fund’s Board of Trustees, including the Trustees who are not interested persons of the Fund (the “Independent Trustees”), unanimously approved the continuation of the Advisory Agreement between the Fund and AllianceBernstein L.P. (the “Adviser”)(the “Advisory Agreement”) at a video conference meeting held on October 27-28, 2021.¹

The following discussion describes the considerations in connection with the Board’s review of the Advisory Agreement.

In connection with the annual review of the continuation of the Advisory Agreement between the Fund and the Adviser, counsel to the Independent Trustees sent a letter to the Adviser dated August 12, 2021, that contained a list of information requested by the Independent Trustees to conduct their annual review. The Board of Trustees, including the Independent Trustees, met by video conference and received and evaluated extensive materials relating to the continuation of the Advisory Agreement from the Adviser. In addition, the Board received materials from the Senior Analyst and an independent fee consultant as described below. On October 5, 2021, the Board of Trustees held a video conference meeting to discuss its review of the Advisory Agreement and the materials the Trustees had been provided. At that meeting, the Independent Trustees met separately with their independent counsel and the Senior Analyst and the independent fee consultant in executive sessions. Following the October 5, 2021 meeting, the Independent Trustees, through counsel, requested certain additional information by means of an email from their independent counsel dated October 7, 2021, and the Adviser provided certain additional information by means of a memorandum dated October 15, 2021. The Independent Trustees held a video conference meeting on October 19, 2021 with their independent counsel and the Senior Analyst to further discuss the contract renewal materials and supplemental materials provided in response to the Board’s request. On October 27-28, 2021, the Board of Trustees held a video conference meeting to continue their review of the Advisory Agreement. During this meeting, the Adviser provided further information requested by the

1 The meeting was held by video conference in view of the ongoing COVID-19 pandemic and based on exemptive relief issued by the Securities and Exchange Commission, with the Board’s intention to ratify the approval of the Advisory Agreement at its next in-person meeting.

abfunds.com AB MULTI-MANAGER ALTERNATIVE FUND    ^|    49

Independent Trustees relating to contract renewal, and the Independent Trustees also met separately with counsel to the Independent Trustees as well as the Senior Analyst to review the contract renewal materials provided by the Adviser and the materials prepared by the Senior Analyst. At the conclusion of this meeting, the Board approved the continuation of the Advisory Agreement for an additional annual term as described below.

In approving the Advisory Agreement, the Board, including the Independent Trustees, considered all information it deemed reasonably necessary to evaluate the terms of the Advisory Agreement and considered whether the Agreement would be in the best interests of the Fund. In particular, the Board considered the information that was provided to them by the Adviser in response to their requests, as well as information prepared by the Senior Analyst and the independent fee consultant at the request of the Board. The Fund’s Senior Analyst assists the Board (as well as the boards of other funds sponsored by the Adviser) in evaluating advisory agreements and certain other agreements pursuant to which the Adviser or its affiliates provide services to the Fund. The Board also considered other information provided to the Board in connection with the October 5, 2021 and October 27-28, 2021 meetings and throughout the past year.

The information considered by the Board included information with respect to the nature, extent and quality of services provided, investment performance, fees and expenses, profitability, economies of scale, and fall-out benefits and other revenue.

In the Board’s consideration of the factors discussed below, no single factor was considered in isolation or to be determinative to the decision of the Board to approve the Advisory Agreement. Rather, the Board concluded, in light of a weighing and balancing of all factors considered and in the exercise of the Trustees’ business judgment, that it was in the best interests of the Fund to approve the Advisory Agreement including the fees to be charged for services thereunder, as summarized below.

Fees and Expenses

The Board, including the Independent Trustees, compared the fees and expense ratios of the Fund against fees and expense ratios of a peer group of funds with similar investment objectives (“peer group”). Both the peer group and the funds within the peer group, with respect to the fee and expense data, were available from Strategic Insight, an independent provider of investment company data. The Trustees noted that the Fund’s contractual advisory fee was below the median of the peer group and that the Fund’s total expense ratio (excluding interest expense and underlying fund expenses) was below the peer group median in the Strategic Insight report. The Senior Analyst also performed analyses of the advisory fees, and compared such analyses to the Fund’s peer group. In addition, the

50    ^|    AB MULTI-MANAGER ALTERNATIVE FUND abfunds.com

Board received and considered information from an independent fee consultant regarding the Fund’s fees and expenses as well as its investment performance.

The Board also received and considered information about the services rendered, and the fee rates charged, to other clients advised by the Adviser, including information about any recent advisory fee changes with respect to other collective funds advised by the Adviser. The Board noted the differences between the services provided to the Fund in comparison to those provided to other types of clients, including offshore funds managed by the Adviser, and the differences in the entrepreneurial and other risks borne by the Adviser in serving the Fund compared to other types of clients.

On the basis of its review and consideration of the fees as described above and the Board’s consideration of the other factors described below, and in light of the Adviser’s reduction of the Fund’s advisory fee in 2018, the Board concluded that the contractual advisory fee as proposed was reasonable.

Nature, Extent and Quality of Services Provided

The Board, including the Independent Trustees, considered the nature, quality and extent of services performed by the Adviser and its affiliates gained from their experience as directors or trustees of the Fund and certain other funds advised by the Adviser, their overall confidence in the Adviser’s integrity and competence they have gained from that experience, and the Adviser’s initiative in identifying and raising potential issues with the Trustees. The Board also considered the Adviser’s responsiveness, frankness and attention to concerns raised by the Trustees from time to time, including the Adviser’s willingness to consider and implement organizational and other changes designed to improve investment results and the services provided to the funds. The Board also considered the scope and quality of the Adviser’s investment management capabilities, other resources dedicated to performing its services, the quality of its compliance, administrative and other services provided to the Fund and the background and experience of the Adviser’s senior management. The Board reviewed the qualifications, backgrounds and responsibilities of the investment staff primarily responsible for day-to-day portfolio management services for the Fund and noted the Adviser’s commitment to strong research and investment management capabilities throughout changing market environments.

In addition to the investment advisory services provided to the Fund, the Trustees considered that the Adviser and its affiliates also provide certain administrative services necessary for the operations of the Fund on an “at cost” basis pursuant to a separate Administrative Reimbursement Agreement. The Board reviewed the compliance and administrative services of the Adviser that support the investment advisory services provided to the Fund.

abfunds.com AB MULTI-MANAGER ALTERNATIVE FUND    ^|    51

The Board also considered how the organizational capabilities and financial condition of the Adviser may affect the nature and quality of its services. In that regard, the Board considered information about the impact of the ongoing COVID-19 pandemic on the Adviser’s operations and the Adviser’s ability to continue to provide the same scope and quality of services to the Fund. The Board considered the ongoing impacts of the relocation of substantial operations of the Adviser from the New York City area to Nashville, Tennessee as well as the implications of a substantial number of the Adviser’s employees working from home during the pandemic.

In considering the nature and quality of the services provided by the Adviser, the Board, including the Independent Trustees, received and considered information about the Fund’s investment performance, as well as the performance of its peer group and the performance of an appropriate benchmark index. The Board was provided with performance data versus the Fund’s benchmark index for the 1-year, 3-year, 5-year and since inception periods ended July 31, 2021, and versus the Fund’s peer group, for the fiscal year ended March 31, 2021 and for each of the prior fiscal years since inception. The Board also received certain updated performance information as of September 30, 2021. In addition, the Trustees considered information showing performance compared to peer groups and the benchmark index for rolling calendar year periods and the year to date. The Trustees also receive detailed comparative performance information for the Fund at each regular Board meeting during the year. The Board noted that in this case the benchmark index is an index of other funds which reflects the fees of such other funds.

The Trustees noted that the Fund’s performance for the year ended March 31, 2021 was below the HFRI Fund of Funds Composite Index but was slightly above the median of the performance group of comparable funds selected by Strategic Insight. The Trustees considered the Adviser’s explanations for performance and measures the Adviser had taken or proposed to take to improve performance. The Trustees noted generally the Adviser’s continued efforts to enhance the services provided to the Fund. The Trustees also noted that they would continue to monitor investment performance closely.

The Board concluded that the Adviser had the experience and resources necessary to provide services of appropriate nature, quality and scope with respect to the Fund.

Profitability

The Board, including the Independent Trustees, considered the level of the Adviser’s profits in respect of its management of the Fund. The materials provided to the Independent Trustees included information indicating the profitability of the Fund to the Adviser for calendar years 2019 and 2020, which had been reviewed by an independent consultant. The Trustees

52    ^|    AB MULTI-MANAGER ALTERNATIVE FUND abfunds.com

reviewed the assumptions and methods of allocation used by the Adviser in preparing fund-specific profitability data, noting that the methodology was consistent with the Adviser’s internal financial reporting. The Trustees acknowledged that there are many potentially acceptable allocation methodologies for cost allocation and that in certain cases the selected allocation methodology may not capture all costs borne by the Adviser with respect to the Fund. The Trustees noted that they received information regarding all revenues and expenses of the Adviser’s relationship with the Fund and that they had focused on profitability before taxes and distribution expenses. The Trustees noted that an affiliate of the Adviser provided distribution services to the Fund at no cost. The amounts recently reimbursed to the Adviser by the Fund were also noted, along with how the reimbursement was accounted for in determining profitability. The Trustees also considered the 2018 reduction of the management fee from 1.50% to 1.00% and then discussed the services and costs associated with the Fund’s Administrative Reimbursement Agreement with the Adviser.

The Trustees reviewed comparative information regarding profitability for other publicly-traded advisers, recognizing that it is difficult to make comparisons of profitability among different investment advisers because only limited comparative information is publicly available and the comparisons are affected by numerous factors including different business mixes.

After reviewing all relevant factors, the Trustees, including the Independent Trustees, concluded that the levels of the Adviser’s profits in respect of its management of the Fund were not excessive.

Economies of Scale

The Board, including the Independent Trustees, considered whether there have been economies of scale in respect of the management of the Fund, whether the Fund has appropriately benefited from any economies of scale, and whether there is potential for realization of any further economies of scale. The Trustees discussed possible ways in which any such economies of scale may be shared with the Fund, including by investment in enhanced services.

The Trustees also considered the Senior Analyst materials which they received in connection with the review of the Advisory Agreement, which included information reflecting changes in asset levels of the Fund and in the profitability of the Adviser over various periods.

After reviewing the profitability and economies of scale information provided by the Adviser, the Board concluded that the benefits of any economies of scale were appropriately being shared with Fund investors by way of, among other things and as applicable, the 2018 fee reduction for the Fund and the Adviser’s continued reinvestment in the business,

abfunds.com AB MULTI-MANAGER ALTERNATIVE FUND    ^|    53

including by researching and implementing new product enhancements. The Trustees also noted that they would continue to monitor the Fund’s growth.

Fall-Out Benefits and Other Revenue

The Board, including the Independent Trustees, also took into account so-called “fall-out benefits” to the Adviser. They also considered other benefits potentially derived from an increase in the Adviser’s business as a result of its relationship with the Fund. The Trustees recognized that the Adviser’s profitability could be lower without these benefits. The Trustees concluded that these fall-out benefits to the Adviser were acceptable.

Advisory Fee Rate Schedule

On the basis of the information considered, the Board determined to approve the continuation of the Advisory Agreement for an additional annual term, without change to the Fund’s contractual fee schedule at an annual rate of 1.00% of the Fund’s net assets.

To provide financial products and services to our clients, we collect nonpublic personal information from a variety of sources, including: (1) information we receive from clients, such as through applications or other forms, which can include a client’s name, address, phone number, social security number, assets, income and other household information, (2) information about client transactions with us, our affiliates and non-affiliated third parties, which can include account balances and transactions history, and (3) information from visitors to our websites provided through online forms, site visitorship data and online information-collecting devices known as “cookies.”

We may disclose all of the nonpublic personal information that we collect about our current and former clients, as described above, to non-affiliated third parties to manage our business and as otherwise required or permitted by law, including those that perform transaction processing or servicing functions, marketing services providers that provide marketing services on our behalf pursuant to a joint marketing agreement, and professional services firms that provide knowledge-based services such as accountants, consultants, lawyers and auditors to help manage client accounts. We require all the third-party providers to adhere to our privacy policy or a functional equivalent.

We may also disclose the nonpublic personal information that we collect about current and former clients, as described above, to our affiliated investment, brokerage, service and insurance companies for the purpose of marketing their products or services to clients under circumstances that are permitted by law, such as if our affiliate has its own relationship with you. We have policies and procedures to ensure that certain conditions are met before an AllianceBernstein affiliated company may use information obtained from another affiliate to solicit clients for marketing purposes.

We will also use nonpublic personal information about our clients for our own internal analysis, analytics, research and development, and to improve and add to our client offerings.

We have policies and procedures designed to safeguard the confidentiality and security of nonpublic personal information about our clients that include restricting access to nonpublic personal information to personnel that have been screened and undergone security and privacy training; to personnel who need it to perform their work functions such as our operations, customer service, account management, finance, quality, vendor management and compliance teams as required to provide services, communicate with you and fulfill our legal obligations.

We employ reasonably designed physical, electronic and procedural safeguards to secure and protect client nonpublic personal information.

If you are in the European Economic Area (“EEA”) or Switzerland, we will comply with applicable legal requirements providing adequate protection for the transfer of personal information to recipients in countries outside of the EEA and Switzerland.
