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, 2018. The table also includes the performance of the Morgan Stanley Capital International (“MSCI”) World Index (net), the Standard and Poor’s (“S&P”) 500 Index and the Bloomberg Barclays US Aggregate Index.

The Fund underperformed the HFRI FOF Composite Index, the MSCI World Index (net) and the S&P 500 Index, but outperformed the Bloomberg Barclays US Aggregate Index, during both periods.

The six-month period was an environment of low monthly volatility, with only modest changes from month to month. Low volatility was a consistent pattern within global bond markets; however, non-US equity markets, particularly Asia, generated negative returns and elevated volatility levels. Therefore, investments in hedge funds with exposure to Asian equity markets detracted. In some cases, the exposures were directional, i.e. long equities, and in other cases the positions were more relative value, such as long equities in China versus short equities in the US.

On a broader scale, the Fund benefited from positive absolute performance across the Long/Short Equity, Credit/Distressed and Event Driven Underlying Portfolios, while Multi-Strategy was the only notable detractor; Global Macro was flat. While the Long/Short Equity Underlying Portfolios with exposure to Asia and emerging-equity markets were a headwind to performance, Underlying Portfolios with exposures to US and, more broadly,

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

global markets, fared much better. The credit-focused Underlying Portfolios managed a positive contribution despite headwinds for the global credit markets from rising interest rates. In fact, the performance of all of the core Credit/Distressed Underlying Portfolios was positive, led by investments in distressed and short-duration high-yielding credit instruments. Event Driven had a successful period with five of the six core Underlying Portfolios positively contributing, the sole outlier producing only a marginal loss due to the performance of hedging positions, rather than the assets held on the long side. The top Event Driven contributors were led by a diverse group of equity and fixed-income positions undergoing meaningful corporate events that unlocked value during the period. The losses within Multi-Strategy were tied primarily to volatility in Asian markets, with relative value positioning long Chinese equities underperforming against shorts across the rest of Asia.

The majority of the underperformance during the 12-month period occurred during the first half of the period. Global Macro was the sole absolute negative contributor; Underlying Portfolios with exposures to select emerging markets, such as Argentina and South Africa, were the largest detractors. The Long/Short Equity allocation was the top contributor, including a positive contribution during the time of high volatility between January and March 2018, but with a more notable shortcoming during the equity rally towards the end of 2017. Several Underlying Portfolios showed strong stock selection in January during the rising market, but also showed meaningful capital preservation during the downside volatility in February and March, from a combination of short stock selection and significant exposure to put options held throughout the period, which helped returns as markets fell. During the October through December period however, poor stock selection across sector-specific funds in energy, health care and technology detracted. Similar to the six-month period, most of the Credit/Distressed Underlying Portfolios contributed, with gains diversified across distressed, high yield and structured credits. The sole negative contributor was positioned significantly net short through hedges across multiple asset classes, negating the gains from the long credit positions. The Event Driven allocation was small and therefore only modestly contributed to returns. Multi-Strategy also contributed, albeit more modestly, from gains across equities, fixed income, mergers and macro-trading strategies.

For both periods, the Fund utilized total return swaps for hedging and investment purposes which had no material impact on absolute performance.

As a result of changes to the Fund’s investment policies that were effective July 31, 2018, including changes to allow for greater direct investment in securities and other financial instruments (in addition to investment in hedge funds), the portfolio composition is expected to evolve over time. However, the changes in investment policies had only a limited impact on the Fund’s performance for the period ended September 30, 2018.

MARKET REVIEW AND INVESTMENT STRATEGY

US stocks outperformed their non-US counterparts during the six-month period ended September 30, 2018. US indices advanced to record highs, amid continued economic strength and strong corporate earnings. Conversely, emerging-market equities fell on the back of a stronger US dollar, rising US interest rates, and fears that financial turmoil in countries such as Turkey and Argentina would spread to other markets. From a style perspective, growth stocks outperformed value stocks. Performance was mixed in terms of market capitalization. Trade wars dominated market-related headlines, while political instability in Europe also weighed on investor sentiment.

Fixed-income markets had mixed performance. Global high yield outperformed the flat returns of developed-market treasuries, while emerging-market local-currency government bonds and investment-grade securities ended the period lower. Emerging-market debt sectors generally sold off. The US Federal Reserve hiked interest rates twice and increased forward guidance, while the European Central Bank started to scale back its asset purchases. Elsewhere, markets responded positively when the Chinese central bank took steps to stop further depreciation of the yuan.

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, Emerging Markets, Global Macro and Multi-Strategy. For more information on these strategies, please see “Consolidated Portfolio of Investments” on pages 8-18. 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 35-37.

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. The MSCI World Index (net, free float-adjusted, market capitalization weighted) represents the equity market performance of developed markets. The S&P 500^® Index includes 500 US stocks and is a common representation of the performance of the overall US stock market. The Bloomberg Barclays US Aggregate 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 may be speculative in that it 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

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

DISCLOSURES AND RISKS (continued)

the Fund in illiquid assets and foreign markets and the use of short sales, 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.

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 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).

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

Long/Short Equity Underlying Portfolios seek to buy securities with the expectation that they will increase in value (called “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 30 – 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.

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. Certain Underlying Portfolios may have lock up periods of up to two years.

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 60 – 90 day redemption notice periods. Certain Underlying Portfolios may have lock up periods of up to three years.

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 30 – 60 day redemption notice periods. Certain Underlying Portfolios may have lock up periods of up to two years.

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 30 – 90 day redemption notice periods. Certain Underlying Portfolios have a lock up period of one year.

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.

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 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, 2018, net assets of the Fund were $1,092,170,298, of which $10,089,368, 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 AB Multi-Manager Alternative 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. Open end mutual funds are valued at the closing net asset value per share.

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.

abfunds.com AB MULTI-MANAGER ALTERNATIVE FUND    ^|    23

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

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.

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.

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 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

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

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. In addition, non-agency rated investments are classified as Level 3.

In May 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-07, Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or its equivalent), as an amendment to Accounting Standards Codification (ASC) 820, Fair Value Measurement. The amendments in this ASU apply to reporting entities that elect to measure the fair value of an investment using the net asset value per share (or its equivalent) practical expedient, as the Fund does for its investments in Underlying Portfolios. The amendments in this ASU remove the requirement to categorize within the fair value hierarchy, as described above, all investments for which fair value is measured using the net asset value per share practical expedient.

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.

The following table summarizes the valuation of the Fund’s investments by the above fair value hierarchy levels as of September 30, 2018:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

** In May 2015, the Financial Accounting Standards Board issued an Accounting Standards Update, ASU 2015-07 (the “ASU”) which removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. The ASU is effective for annual periods beginning after December 15, 2015 and interim periods within those annual periods, with application of the amendments noted above retrospectively to all periods presented. The retrospective approach requires that an investment for which fair value is measured using the net asset value per share practical expedient be removed from the fair value hierarchy in all periods presented herein. Accordingly, the total investments of the Underlying Portfolios with a fair value of $959,656,842 have not been categorized in the fair value hierarchy.

The Fund recognizes all transfers between levels of the fair value hierarchy assuming the financial instruments were transferred at the beginning of the reporting period.

2. Cash Committed

As of September 30, 2018, the Fund has committed to purchase the following Underlying Portfolios for effective date October 1, 2018:

Underlying Portfolios	Amount Committed
Indaba Capital Partners (Cayman), L.P*	$  15,000,000

* Investments paid in advance amounted to $15,000,000.

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 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

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

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.

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.

6. Expenses

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

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.

8. Offering Expenses

Offering expenses of $37,000 were deferred and amortized on a straight line basis over a one year period starting from September 21, 2018 (Subsidiary’s commencement of operations).

NOTE B

Management Fee and Other Transactions with Affiliates

Under the terms of the investment advisory agreement in effect during the reporting period (the “Advisory Agreement”), the Fund paid the Investment Manager a management fee at an annual rate of 1.50% 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

abfunds.com AB MULTI-MANAGER ALTERNATIVE FUND    ^|    27

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

day of the subsequent month (the “Management Fee”). The Management Fee is payable in arrears as of the last day of the subsequent month.

In addition, effective June 1, 2018, the Investment Manager agreed to waive a portion of its management fee so that the Fund paid management fees at an annual rate of 1.00% 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. This waiver could not be terminated by the Investment Manager prior to July 31, 2019 without the approval of the Board. For the six months ended September 30, 2018, such reimbursements/waivers amounted to $1,908,158.

Under a separate administrative 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, 2018, the reimbursement for such fees amounted to $167,867.

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 $115,946 for the six months ended September 30, 2018.

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. Effective August 1, 2018 the Adviser has contractually agreed to waive .10% of the advisory fee of the Government Money Market Portfolio until August 31, 2019. In connection with the investment by the Fund in the 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, 2018, such waiver amounted to $44,103.

Purchases and sales of investments in the Underlying Portfolios, aggregated $153,900,000 and $368,008,282, respectively, for the six months ended September 30, 2018.

The cost of investments for federal income tax purposes was substantially the same as the cost for financial reporting purposes. Accordingly, gross unrealized appreciation and unrealized depreciation are as follows:

Gross unrealized appreciation	$	139,732,035
Gross unrealized depreciation		(7,540,147	)
Net unrealized appreciation	$	132,191,888

2. Derivative Financial Instruments

The Fund may use derivatives in an effort 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.

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 their exposure to interest rates, credit risk, or currencies. Certain Portfolios may also enter into swaps for non-hedging purposes as a means of gaining market exposures, including by making direct investments in foreign currencies, as described below under “Currency Transactions.” 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

abfunds.com AB MULTI-MANAGER ALTERNATIVE FUND    ^|    29

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

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 OTC 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 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, 2018, the Fund held total return swaps for hedging and non-hedging purposes.

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

The Fund and the Subsidiary typically enters into International Swaps and Derivatives Association, Inc. Master Agreements (“ISDA Master Agreement”) with its OTC derivative contract counterparties in order to, among other things, reduce its 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 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 and the Subsidiary net liability, held by the defaulting party, may be delayed or denied.

The Fund 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 and the Subsidiary 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.

During the six months ended September 30, 2018, the Fund had entered into the following derivatives:

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. A 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

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

times, in those amounts, and on such terms and conditions as the Board of Trustees 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 shares will generally be made by the Fund approximately 45 days following the Valuation Date.

Transactions in shares of beneficial interest were as follows for the six months ended September 30, 2018 and year ended March 31, 2018:

	Shares						Amount

NOTE E

Risks Involved in Investing in the Fund

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.

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

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. Such risks 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, 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 may utilize leverage in pursuit of achieving a potentially greater investment return. The use of leverage exposes an Underlying Portfolio to additional risk including (i) greater losses from investments than would otherwise have been the case had the Underlying Portfolio not used leverage to make the investments; (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 Underlying Portfolio’s 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 may invest in securities of foreign companies that involve special risks and considerations not typically associated with investments in the United States, due to concentrated investments in a

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

limited number of countries or regions, which may vary throughout the year depending on the Underlying Portfolio. Such concentrations may subject the Underlying Portfolios 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.

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.

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 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.

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.

NOTE F

Tax Information

The tax character of fiscal year-end distributions for 2018 is based on estimated tax information provided by certain Underlying Portfolios. The character may materially change as the Fund receives final 2017 tax reporting from Underlying Portfolios. The tax character of distributions paid during the fiscal years ended March 31, 2018 and March 31, 2017 were as follows:

	2018			2017
Distributions paid from:
Ordinary income	$	12,605,284		$	2,840,922
Return of capital		2,494,217			– 0	–
Long-term capital gains		– 0	–		7,989,905
Total taxable distributions paid	$	15,099,501		$	10,830,827

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

As of March 31, 2018, the components of accumulated earnings/(deficit) on a tax basis were as follows:

Undistributed net investment income	$	– 0	–
Accumulated capital and other losses		(10,293,384	)(a)
Unrealized appreciation/(depreciation)		34,689,162	(b)
Total accumulated earnings/(deficit)	$	24,395,778

(a) At March 31, 2018, the Fund had a qualified late-year ordinary loss deferral of $5,363,236 and a post-October short-term capital loss deferral of $3,031,761. These losses are deemed to arise on April 1, 2018.

(b) 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 partnerships.

For tax purposes, net 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. During the current fiscal year, the Fund utilized $8,399,038 of prior year capital losses. As of March 31, 2018, the Fund has $1,898,387 in short-term carry forward capital losses.

NOTE G

Credit Facility

The Fund is a party to a $75 million 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. Credit Facility fees are paid by the Fund and are included in the consolidated statement of operations. The Fund had no borrowings outstanding from the Facility at September 30, 2018. For the six months ended September 30, 2018, the Fund had borrowings under the Agreement as follows:

Average Daily Loan Balance*	Maximum Daily Loan Outstanding	Weighted Average Interest Rate
$    18,000,000	$    18,000,000	3.44%

* For 6 days borrowings were outstanding.

NOTE H

Recent Accounting Pronouncement

In August 2018, the Financial Accounting Standards Board issued an Accounting Standards Update, ASU 2018-13, Fair Value Measurement (Topic 820), Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement which removes, modifies and adds disclosures to Topic 820. The amendments in this ASU 2018-13 apply to all entities that are required, under existing U.S. GAAP, to make disclosures about recurring or nonrecurring fair value measurements. The amendments in this ASU 2018-13 are effective for all entities for fiscal years, and

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

interim periods within those fiscal years, beginning after December 15, 2019. At this time, management is evaluating the implications of these changes on the consolidated financial statements.

In October 2018, the U.S. Securities and Exchange Commission adopted amendments to certain disclosure requirements included in Regulation S-X that had become “redundant, duplicative, overlapping, outdated or superseded, in light of the other Commission disclosure requirements, GAAP or changes in the information environment.” The compliance date for the amendments to Regulation S-X was November 5, 2018 (for reporting period end dates of September 30, 2018 or after). Management has evaluated the impact of the amendments and determined the effect of the adoption of the rules will simplify certain disclosure requirements on the consolidated financial statements.

NOTE I

Subsequent Events

Effective October 26, 2018, the Credit Facility was decreased to $50 million.

Effective November 1, 2018, the Advisory Agreement was amended so that the Fund pays a management fee at an annual rate of 1.00% 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. By making the 1.00% management fee part of the Advisory Agreement, the amendment effectively supersedes the management fee waiver addressed in Note B above.

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

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

At a meeting held on July 24, 2018, the Trustees of Fund met in person to consider a New Management Agreement for the Fund required as a result of AXA S.A. planning to sell its remaining shares in AXA Equitable Holdings, Inc., the entity that holds a majority of the partnership interests in the Manager and is the parent of the Manager’s sole general partner (the “Plan”). In connection with their deliberations, the Trustees held discussions with management and reviewed certain written materials, memoranda, presentations and analyses relating to the Fund, including materials from the Manager and counsel to the Independent Trustees which: (i) included information concerning the Manager’s organization, including with respect to the Plan, the services rendered to the Fund by the Manager, the fees paid by the Fund to the Manager and the estimated profitability of the Manager with respect to its relationship with the Fund; and (ii) outlined the legal duties of the Board under the 1940 Act. The Board Materials also contained information from Strategic Insight”), an information service provider unaffiliated with the Manager, including a draft report (“Strategic Insight Report”) comparing the Fund’s fee rate for advisory services to those of other alternative strategy closed-end funds selected by Strategic Insight.

The Trustees discussed with counsel the legal standards regarding the approval of the New Management Agreement and the 15a-4 Agreement and reviewed the information included in the Board Materials.

The Trustees considered information received throughout the year regarding the Fund, the Manager and the services provided under the current investment management agreement. In connection with their approval of the New Management Agreement, the Board considered its conclusions in connection with their most recent approvals of the current investment management agreement that was in effect at the time of the Board’s approval of the New Management Agreement. The Board also took note of the Manager’s agreement to waive 50 basis points (of its 150 basis point fee under the current investment management agreement) for a one-year period. The Board considered representations by representatives of the Manager that the Fund was not expected to experience any change in the nature and quality of services delivered by the Manager as a result of the Plan. The Trustees considered the fact that the New Management Agreement would have corresponding terms and conditions identical to those of the current investment management agreement with the exception of the effective date under the New Management Agreement.

The Trustees discussed the Board Materials with management and representatives of the Manager responded to questions from the Trustees. The Trustees also held discussions in executive session with their independent counsel, outside the presence of management. After discussing a range of

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

issues, the Trustees considered, among other relevant matters, the following factors:

(a) The nature, extent and quality of services provided by the Manager. The Trustees discussed with representatives of the Manager the services that the Manager provides to the Fund under the current investment management agreement and the expectation that there would be no change in such services under the New Management Agreement. The Trustees discussed the resources available to the Manager, including its research and compliance capabilities. The Board also considered representations by representatives of the Manager that the Manager would continue to have adequate resources following a transaction that constitutes a change of control event as discussed at the Meeting.

The Trustees noted the size and experience of the Manager’s staff, and the experience of its key personnel in providing investment management services. The Manager’s investment diligence and risk management capabilities were also considered. The Trustees took into account that the Trustees regularly receive reports from the Manager regarding the Fund’s performance and the Adviser’s compliance history and compliance program. The Trustees also noted the discussions they had with officers of the Adviser regarding the management of the Fund’s investments and the investment strategies to which the Fund has exposure. During these discussions with Fund officers and representatives of the Manager, the Trustees asked detailed questions of, and received substantive answers from, these representatives regarding the implementation of the Fund’s investment strategy, its efficacy and potential risks.

In addition to the investment advisory services provided to the Fund, the Trustees considered that the Manager 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 Trustees noted that the Manager has an administrative, legal and compliance staff to ensure a high level of quality in the compliance and other services provided to the Fund, including its oversight of the Fund’s day-to-day operations. Based on the presentations made during their meetings and their knowledge of management and Fund operations gained during their tenure as trustees of the Fund, the Trustees concluded that the services provided to the Fund by the Manager under the current investment management agreement were of a high quality and benefited the fund and would be expected to be the same under the New Management Agreement.

(b) Investment performance of the Fund and the Manager. The Trustees reviewed performance information for the Fund, noting that they receive performance reports at regular board meetings and monitor the Fund’s performance throughout the year. The Trustees discussed the Fund’s

abfunds.com AB MULTI-MANAGER ALTERNATIVE FUND    ^|    43

performance with representatives of the Manager, including as compared to relevant benchmarks. The Trustees also reviewed the performance information provided in the Strategic Insight Report. The Trustees concluded that the Fund’s performance was generally in line with expectations in light of the strategies used by the Fund and current market conditions. The Trustees took note that a majority of the performance considered was achieved by the prior portfolio management team. The Trustees also considered the experience, resources and strengths of the Manager and its affiliates in managing funds of funds, including the experience of the portfolio management team in managing multi-strategy funds. Based on these factors, the Trustees determined that the Manager continues to be an appropriate investment manager for the Fund and for purposes of approving the New Management Agreement.

(c) Cost of the services provided and profits realized by the Manager from the relationship with the Fund. The Trustees considered the profitability of the Manager. The Trustees discussed in detail with representatives of the Manager and independent consultants the Manager’s profitability and the methodology used in the profitability analysis. The Trustees noted that an affiliate of the Manager provided distribution services to the Fund at no cost. The amounts recently reimbursed to the Manager by the Fund were also noted. The Trustees also considered the services and costs associated with the Fund’s Administrative Reimbursement Agreement with the Manager. The Trustees considered the Manager’s agreement to waive a portion of its management (constituting more than 30% of the contractual fee rate under the current investment management agreement) for a period of at least a year. The Trustees noted that the Manager’s profitability does not appear to be unreasonable in respect of the Fund.

(d) Economies of scale and whether fee levels reflect these economies of scale. The Trustees discussed whether any economies of scale have been realized for the Fund. The Trustees considered the initial level of advisory fees set for the Fund, the Manager’s agreement to waive a portion of its management fee, recent rates of tenders of fund shares and the potential for economies of scale. The Trustees concluded that any economies of scale achieved by the Manager were not unreasonable under the current advisory arrangements.

(e) Comparison of services rendered and fees paid to those under other investment advisory contracts, such as contracts of the same and other investment advisers or other clients. The Trustees were aware of the services rendered and the fees paid under the current investment management agreement in comparison to other contracts of the Manager with respect to private investment vehicles managed in a similar manner to the Fund and were provided with updated information regarding contractual fee rates of other investment advisers with respect to other closed-end registered investment companies with similar investment programs as the Fund. The

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

Trustees noted the Manager’s representation that providing advisory services to a registered investment company entailed different, and potentially greater, business and regulatory risks than those associated with providing services to the Manager’s other funds and accounts. The Trustees also discussed the fee structure of the Manager’s institutional accounts. The Trustees discussed the management of the comparable institutional accounts, including the allocation of opportunities available to those funds.

The Trustees reviewed with representatives of the Manager the information included in the Strategic Insight Report. The Trustees also noted that the Fund’s total expense ratio was competitive with the expense group median in the Strategic Insight Report. The Trustees reviewed the list of funds provided by Strategic Insight. They discussed whether certain funds should be viewed as comparable to the Fund. The Trustees noted the difficulty in obtaining comparable peer funds, particularly finding funds of comparable size and strategy. The Trustees discussed the Strategic Insight Report with the Manager, including the comparison of advisory fees and expense ratios.

Conclusion. No single factor was determinative to the decision of the Trustees. Based on the foregoing and such other matters as were deemed relevant, all of the Trustees concluded that the advisory fee rate under the New Management Agreement was reasonable in relation to the services provided by the Manager. The Trustees determined that the selection of the Manager to manage the Fund, and the overall arrangements between the Fund and the Manager, as provided in the New Management Agreement, were fair and reasonable in light of the services performed under the current investment management agreement and to be performed under the New Management Agreement, expenses incurred and to be incurred and such other matters as the Trustees considered relevant in the exercise of their business judgment. Based on these factors, the Trustees decided to approve the New Management Agreement.

15a-4 Agreement

In approving the 15a-4 Agreement, the Board, with the assistance of independent counsel, considered similar factors to those considered in approving the New Management Agreement. The Trustees noted that the 15a-4 Agreement is identical to the New Management Agreement, as well as the current investment management agreement, in all material respects except for their proposed effective and termination dates and provisions intended to comply with the requirements of Rule 15a-4 under the 1940 Act, such as provisions requiring escrow of advisory fees. The Trustees considered that under the 15a-4 Agreement, the Manager would continue to manage the Fund pursuant to the 15a-4 Agreement until a new advisory agreement was approved by shareholders or until the end of the 150-day period, whichever would occur earlier. The Trustees also noted that all fees earned by the Manager under the 15a-4 Agreement would be held in escrow pending shareholder approval of the New Management Agreement.
