BBF BlackRock Municipal Income Investment Trust

PROPOSAL 2—ISSUANCE OF ACQUIRING FUND COMMON SHARES

In connection with the proposed Reorganizations described under “Proposal 1: Reorganizations of the Funds,” the common shareholders and the VMTP Holders of the Acquiring Fund are being asked to approve the issuance of additional Acquiring Fund common shares.

Please see “Information about the Common Shares of the Funds” for information about the Funds’ common shares.

In the Reorganization, the Acquiring Fund will acquire substantially all of the assets of the applicable Target Fund and assume substantially all of the liabilities of the applicable Target Fund in exchange for newly issued Acquiring Fund common shares, with a par value $0.001 per share, and newly issued Acquiring Fund VMTP Shares, with a par value of $0.001 per share and liquidation preference of $100,000 per share (plus any accumulated and unpaid dividends that have accrued on the Target Fund VMTP Shares up to and including the day immediately preceding the Closing Date if such dividends have not been paid prior to the Closing Date). The Acquiring Fund will list the newly issued common shares on the NYSE. Each Target Fund will distribute Acquiring Fund Shares received by it pro rata to its shareholders (although cash may be paid in lieu of any fractional common shares). The newly-issued Acquiring Fund Shares will be issued in the form of book-entry interests. Such distribution of Acquiring Fund Shares to Target Fund shareholders will be accomplished by opening new accounts on the books of the Acquiring Fund in the names of the Target Fund shareholders and transferring to those shareholder accounts Acquiring Fund Shares.

The Acquiring Fund will continue to operate after the Reorganizations as a registered, diversified, closed-end management investment company with the investment objective, investment strategies, investment policies and investment restrictions described in this Proxy Statement. As a result of the Reorganizations, however, a shareholder of each Fund may hold a reduced percentage of ownership in the larger Combined Fund than such shareholder did in any of the individual Funds before the Reorganizations.

If the Issuance with respect to a Fund’s Reorganization(s) is not approved, the Investment Advisor may, in connection with ongoing management of that Fund and its product line, recommend alternative proposals to the Board of that Fund.

The Board of the Acquiring Fund recommends that the Acquiring Fund VMTP Holders vote “FOR” each Issuance at the Special Meeting.

The affirmative vote of shareholders representing the holders of a majority of the outstanding Acquiring Fund common shares and Acquiring Fund VMTP Shares present at the Special Meeting or represented by proxy, voting together as a single class, is required to approve each Issuance. For additional information regarding voting requirements, see “Vote Required and Manner of Voting Proxies.”

Subject to the requisite approval of the shareholders of each Fund with respect to the Reorganization, as well as certain consents, confirmations and/or waivers from various third parties, including the liquidity provider with respect to the outstanding BBF VRDP Shares, it is expected that the Closing Date of the Reorganizations will be sometime during the first quarter of 2021, but it may be at a different time as described herein.

INFORMATION ABOUT THE PREFERRED SHARES OF THE FUNDS

BBF’s, BSD’s, MFT’s and the Acquiring Fund’s respective Agreement and Declaration of Trust authorizes the issuance of an unlimited number of shares, par value $.001 per share, all of which were initially classified as common shares. The Board of each Fund is authorized, however, to reclassify any unissued common shares to preferred shares without the approval of its common shareholders.

Upon the closing of the Reorganization, the Target Funds VMTP Holders will receive on a one-for-one basis one newly issued Acquiring Fund VMTP Share, par value $0.001 per share and with a liquidation preference of $100,000 per share (plus any accumulated and unpaid dividends that have accrued on such Target Fund VMTP Share up to and including the day immediately preceding the Closing Date if such dividends have not been paid prior to the Closing Date), in exchange for each Target Fund VMTP Share held by such Target Fund VMTP Holder immediately prior to the Closing Date. The newly issued Acquiring Fund VMTP Share may be of the same series as the Acquiring Fund’s outstanding VMTP Shares or a substantially identical series. No fractional Acquiring Fund VMTP Shares will be issued. The terms of the Acquiring Fund VMTP Shares to be issued in connection with the Reorganizations will be substantially identical to the terms of the Acquiring Fund’s outstanding VMTP Shares and will rank on parity with the Acquiring Fund’s outstanding VMTP Shares as to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund. The newly issued Acquiring Fund VMTP Shares will have the same term redemption date applicable to the outstanding Acquiring Fund VMTP Shares as of the Closing Date of the Reorganization. Such term redemption date is July 2, 2021, unless extended. The Reorganizations will not result in any changes to the terms of the Acquiring Fund’s VMTP Shares currently outstanding.

The newly issued Acquiring Fund VMTP Shares will have terms that are substantially identical to the terms of the currently outstanding BSD and MFT VMTP Shares and the BBF VMTP Shares to be issued in connection with the VRDP Refinancing, including the same term redemption date of July 2, 2021.

In connection with the Reorganizations, and assuming that the VRDP Refinancing is completed prior to the Closing Date of the BBF Reorganization, the Acquiring Fund expects to issue 429 additional VMTP Shares to BSD VMTP Holders, 565 additional VMTP Shares to MFT VMTP Holders and 520 additional VMTP Shares to BBF VMTP Holders. Following the completion of the Reorganizations, the Combined Fund is expected to have 3,027 VMTP Shares outstanding. As a result of the Reorganizations, the Acquiring Fund’s Statement of Preferences will be amended to authorize an additional 1,514 VMTP Shares. A form of such amendment is attached as Appendix C.

Set forth below is information about each Fund’s preferred shares as of August 31, 2020.

The outstanding preferred shares of each Fund are fully paid and non-assessable and have no preemptive or cumulative voting rights.

39

Below is a table that details, as of August 31, 2020, (i) each Fund’s current leverage attributable to preferred shares as a percentage of its total net assets, (ii) the Combined Fund’s leverage attributable to preferred shares on a pro forma basis as a percentage of its total net assets assuming only the BSD Reorganization was consummated as of August 31, 2020, and (iii) the Combined Fund’s leverage attributable to preferred shares on a pro forma basis as a percentage of its total net assets assuming all of the Reorganizations were consummated as of August 31, 2020.

BBF has issued VRDP Shares, $100,000 liquidation value per share. The Acquiring Fund has issued, and following the VRDP Refinancing BBF will issue, VMTP Shares, $100,000 liquidation value per share, with substantially identical terms. Please see “—Description of the VMTP Shares of the Acquiring Fund, BSD and MFT,” “—Description of the VRDP Shares of BBF” for additional information.

BSD, MFT and the Acquiring Fund have each issued VMTP Shares, $100,000 liquidation value per share, with substantially identical terms, including the same term redemption date of July 2, 2021. BBF has issued VRDP Shares, $100,000 liquidation value per share, with a mandatory redemption date of October 1, 2041. The outstanding VRDP Shares of BBF are currently in a one year Special Rate Period that will end on April 15, 2021, unless extended. Please see “—Description of the VMTP Shares of the Acquiring Fund, BSD and MFT,” “—Description of the VRDP Shares of BBF” for additional information.

The VMTP Shares and VRDP Shares were offered to qualified institutional buyers in private transactions exempt from registration under the Securities Act.

The annualized dividend rates for the preferred shares for each Fund’s most recent fiscal year end were as follows:

If the BBF Reorganization Agreement is approved by its shareholders, prior to the Closing Date of the Reorganizations, it is expected that BBF will issue VMTP Shares with terms substantially identical to the terms of the Acquiring Fund VMTP Shares and use the proceeds from such issuance to redeem all of outstanding VRDP Shares of BBF, respectively. The BBF VMTP Shares that will be issued in connection with the VRDP Refinancing will have the same $100,000 liquidation preference per share, dividend period, dividend payment

40

date, voting rights, redemption provisions, transfer restrictions and covenants with respect to effective leverage, asset coverage and eligible investments, mechanism for determining the applicable dividend rate and maximum rate, and the same redemption and paying agent as the outstanding Acquiring Fund VMTP Shares. If the VRDP Refinancing is not completed prior to the Closing Date of the BBF Reorganization, then the BBF Reorganization will not be consummated.

In connection with the Reorganizations, the Acquiring Fund expects to issue 429 additional VMTP Shares to BSD VMTP Holders, 565 additional VMTP Shares to MFT VMTP Holders and 520 additional VMTP Shares to BBF VMTP Holders. Following the completion of the Reorganizations, the Combined Fund is expected to have 3,027 VMTP Shares outstanding. Assuming all of the Reorganizations are approved by shareholders and the VRDP Refinancing is completed prior to the Closing Date of the BBF Reorganization, upon the Closing Date of the Reorganizations, BSD, MFT and BBF VMTP Holders will receive on a one-for-one basis one newly issued Acquiring Fund VMTP Share, par value $0.001 per share and with a liquidation preference of $100,000 per share (plus any accumulated and unpaid dividends that have accrued on the BSD, MFT or BBF VMTP Shares up to and including the day immediately preceding the Closing Date of the Reorganizations if such dividends have not been paid prior to the Closing Date), in exchange for each BSD, MFT or BBF VMTP Share held by the BSD, MFT or BBF VMTP Holders immediately prior to the Closing Date. The newly issued Acquiring Fund VMTP Shares will have terms that are substantially identical to the terms of the BBF VMTP Shares to be issued in connection with the VRDP Refinancing. The newly issued Acquiring Fund VMTP Shares may be of the same series as the Acquiring Fund’s outstanding VMTP Shares or a substantially identical series. No fractional Acquiring Fund VMTP Shares will be issued. The terms of the Acquiring Fund VMTP Shares to be issued in connection with the Reorganizations will be substantially identical to the terms of the Acquiring Fund’s outstanding VMTP Shares and will rank on parity with the Acquiring Fund’s outstanding VMTP Shares as to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund. The newly issued Acquiring Fund VMTP Shares will have the same term redemption date applicable to the outstanding Acquiring Fund VMTP Shares as of the Closing Date of the Reorganization. Such term redemption date is July 2, 2021, unless extended. The Reorganizations will not result in any changes to the terms of the Acquiring Fund’s VMTP Shares currently outstanding.

The newly issued Acquiring Fund VMTP Shares will have terms that are substantially identical to the terms of the currently outstanding BSD and MFT VMTP Shares and the BBF VMTP Shares to be issued in the VRDP Refinancing, including the same term redemption date of July 2, 2021.

Description of the VMTP Shares of the Acquiring Fund, BSD and MFT

Each of the Acquiring Fund’s, BSD’s and MFT’s VMTP Shares may be redeemed, in whole or in part, at any time at the option of the Acquiring Fund, BSD or MFT, as applicable. The redemption price per VMTP Share is equal to the liquidation preference per share plus any outstanding unpaid dividends. Each of the Acquiring Fund, BSD and MFT is required to redeem its VMTP Shares on the term redemption date of the VMTP Shares, unless earlier redeemed or repurchased or unless extended. Such term redemption date is July 2, 2021, unless extended. Six months prior to the term redemption date of the VMTP Shares, each of the Acquiring Fund, BSD and MFT is required to begin to segregate liquid assets with such Fund’s custodian to fund the redemption. In addition, each of the Acquiring Fund, BSD and MFT is required to redeem certain of its outstanding VMTP Shares if it fails to comply with certain asset coverage, basic maintenance amount or leverage requirements.

Dividends on the Acquiring Fund’s, BSD’s and MFT’s VMTP Shares are declared daily and payable monthly at a variable rate set weekly at a fixed rate spread to 0.75% of the one-month LIBOR Rate. The fixed spread is determined based on the long-term preferred share rating assigned to the Acquiring Fund’s, BSD’s and MFT’s VMTP Shares by the ratings agencies then rating the Acquiring Fund’s, BSD’s and MFT’s VMTP Shares. At the date of issuance, the Acquiring Fund’s, BSD’s and MFT’s VMTP Shares were assigned long-term ratings of Aaa from Moody’s and AAA from Fitch. Subsequent to the issuance of the Acquiring Fund’s, BSD’s and

41

MFT’s VMTP Shares, Moody’s completed a review of its methodology for rating securities issued by registered closed-end funds. As of August 31, 2020, the Acquiring Fund’s VMTP Shares were assigned a long-term rating of Aa1 from Moody’s under its new rating methodology. The Acquiring Fund’s VMTP Shares continue to be assigned a long-term rating of AAA from Fitch. As of April 30, 2020, BSD’s VMTP Shares were assigned a long-term rating of Aa1 from Moody’s under its new rating methodology. BSD’s VMTP Shares continue to be assigned a long-term rating of AAA from Fitch. As of July 31, 2020, MFT’s VMTP Shares were assigned a long-term rating of Aa1 from Moody’s under its new rating methodology. MFT’s VMTP Shares continue to be assigned a long-term rating of AAA from Fitch. The dividend rate on the Acquiring Fund’s, BSD’s and MFT’s VMTP Shares is subject to a step-up spread if such Fund fails to comply with certain provisions, including, among other things, the timely payment of dividends, redemptions or gross-up payments, and complying with certain asset coverage and leverage requirements. For the fiscal year ended August 31, 2020, the annualized dividend rate for the VMTP Shares of the Acquiring Fund was 1.67%. For the fiscal year ended April 30, 2020, the annualized dividend rate for the VMTP Shares of BSD was 2.18%. For the fiscal year ended July 31, 2020, the annualized dividend rate for the VMTP Shares of MFT was 1.79%.

The Acquiring Fund’s, BSD’s and MFT’s VMTP Shares are subject to certain restrictions on transfer, and each of the Acquiring Fund, BSD and MFT may also be required to register its VMTP Shares for sale under the Securities Act under certain circumstances. In addition, amendments to the Acquiring Fund’s, BSD’s and MFT’s VMTP Shares’ governing documents generally require the consent of the holders of VMTP Shares.

For each of the Acquiring Fund, BSD and MFT, its VMTP Shares rank prior to such Fund’s common shares as to the payment of dividends by the Fund, and distribution of assets upon dissolution or liquidation of the Fund. For each of the Acquiring Fund, BSD and MFT, the 1940 Act prohibits the declaration of any dividend on the Fund’s common shares or the repurchase of the Fund’s common shares if the Fund fails to maintain asset coverage of at least 200% of the liquidation preference of the Fund’s outstanding VMTP Shares. In addition, pursuant to the VMTP Shares’ governing instruments, each of the Acquiring Fund, BSD and MFT are restricted from declaring and paying dividends on classes of shares ranking junior to or on parity with the such Fund’s VMTP Shares or repurchasing such shares if the Fund fails to declare and pay dividends on the VMTP Shares, redeem any VMTP Shares required to be redeemed under the VMTP Shares’ governing instruments or comply with the basic maintenance amount requirement of the ratings agencies rating the VMTP Shares.

For each of the Acquiring Fund, BSD and MFT, the holders of the Fund’s VMTP Shares have voting rights equal to the voting rights of the holders of the Fund’s common shares (one vote per share) and will vote together with holders of the Fund’s common shares (one vote per share) as a single class on certain matters. However, for each of the Acquiring Fund, BSD, and MFT, the VMTP Shareholders, voting as a separate class, are also entitled to elect two trustees to the Board of the Fund. For each of the Acquiring Fund, BSD and MFT, VMTP Shareholders are also entitled to elect the Fund’s full board of trustees if dividends on the VMTP Shares are not paid for a period of two years. VMTP Shareholders are also generally entitled to a separate class vote to amend the VMTP Shares’ governing documents. In addition, the 1940 Act requires the approval of the holders of a majority of any outstanding VMTP Shares, voting as a separate class, to (a) adopt any plan of reorganization that would adversely affect the VMTP Shares, (b) change the applicable Fund’s sub-classification as a closed-end investment company or change its fundamental investment restrictions or (c) change its business so as to cease to be an investment company.

Description of the VRDP Shares of BBF

If the BBF Reorganization Agreement is approved by BBF shareholders, prior to the Closing Date of the BBF Reorganization, it is expected that BBF will issue VMTP Shares with terms substantially identical to the terms of the outstanding Acquiring Fund VMTP Shares and use the proceeds from such issuance to redeem all of outstanding VRDP Shares of BBF.

BBF’s VRDP Shares have the benefit of an unconditional demand feature pursuant to a purchase agreement provided by Bank of America, N.A. acting as liquidity provider to ensure full and timely repayment of the

42

liquidation preference amount plus any accumulated and unpaid dividends to holders upon the occurrence of certain events (the “Liquidity Facility”). BBF entered into a fee agreement with the liquidity provider (the “Fee Agreement”) in connection with the Liquidity Facility that requires a per annum liquidity fee payable to the liquidity provider. The Fee Agreement between BBF and the liquidity provider is scheduled to expire, unless renewed or terminated in advance, on April 30, 2021.

The Liquidity Facility requires the liquidity provider to purchase all BBF’s VRDP Shares tendered for sale that were not successfully remarketed. BBF is required to redeem its VRDP Shares owned by the liquidity provider after six months of continuous, unsuccessful remarketing. Upon the occurrence of the first unsuccessful remarketing, BBF is required to segregate liquid assets to fund the redemption.

In the event the VRDP Shares Purchase Agreement (the “Purchase Agreement”) for BBF is not renewed, and BBF does not arrange for a Purchase Agreement with an alternate liquidity provider, BBF’s VRDP Shares will be subject to mandatory purchase by the liquidity provider prior to the termination of the Purchase Agreement. There is no assurance BBF will replace such redeemed VRDP Shares with any other preferred shares or other form of leverage.

Except during the Special Rate Period (as defined and described below), VRDP Holders have the right to give notice on any business day to tender BBF’s VRDP Shares for remarketing in seven days, the VRDP Shares are subject to a mandatory tender for remarketing upon the occurrence of certain events, and should a remarketing be unsuccessful, the dividend rate for such VRDP Shares will reset to a maximum rate as defined in the governing documents of the VRDP Shares. BBF’s VRDP Shares are also subject to certain restrictions on transfer outside of the remarketing process. Except during the Special Rate Period, BBF may incur remarketing fees at the annual rate of 0.10% on the aggregate principal amount of the VRDP Shares.

BBF is required to redeem its VRDP Shares on October 1, 2041, the mandatory redemption date for such VRDP Shares, unless earlier redeemed or repurchased. Six months prior to the mandatory redemption date, BBF is required to begin to segregate liquid assets with its custodian to fund the redemption. In addition, BBF is required to redeem certain of its outstanding VRDP Shares if it fails to maintain certain asset coverage, basic maintenance amount or leverage requirements.

Subject to certain conditions, BBF’s VRDP Shares may be redeemed, in whole or in part, at any time at the option of BBF. The redemption price per VRDP Share is equal to the liquidation value per VRDP Share plus any outstanding unpaid dividends, except that a redemption premium may be applicable during the Special Rate Period.

Except during the Special Rate Period, dividends on BBF’s VRDP Shares are payable monthly at a variable rate set weekly by the remarketing agent. Such dividend rates are generally based upon a spread over a base rate and cannot exceed a maximum rate. In the event of a failed remarketing, the dividend rate of the VRDP Shares will be reset to a maximum rate. The maximum rate is determined based on, among other things, the long-term preferred share rating assigned to the VRDP Shares and the length of time that the VRDP Shares fail to be remarketed. The maximum rate of the VRDP Shares will not exceed 15% per annum, exclusive of any applicable gross-up payments or increased dividend payment relating to the inclusion in any dividend of net capital gains or ordinary income taxable for regular U.S. federal income tax purposes. At the date of issuance, the VRDP Shares of BBF were assigned a long-term rating of Aaa from Moody’s and AAA from Fitch. Subsequent to the issuance of the VRDP Shares, Moody’s completed a review of its methodology for rating securities issued by registered closed-end funds. As of September 30, 2020, the VRDP Shares of BBF were assigned a long-term rating of Aa2 from Moody’s under its new ratings methodology. The VRDP Shares of BBF continue to be assigned a long-term rating of AAA from Fitch.

The short-term ratings on the VRDP Shares were withdrawn by Moody’s, Fitch and/or S&P at the commencement of the Special Rate Period, as described below. The short-term ratings on BBF’s VRDP Shares are directly related to the short-term ratings of the liquidity provider for such VRDP Shares. Changes in the

43

credit quality of the liquidity provider could cause a change in the short-term credit ratings of the VRDP Shares. Except during the Special Rate Period, a change in the short-term credit rating of the liquidity provider or the VRDP Shares may adversely affect the dividend rate paid on such VRDP Shares, although the dividend rate paid on the VRDP Shares is not directly related to the short-term rating. The liquidity provider may be terminated prior to the scheduled termination date if the liquidity provider fails to maintain short-term debt ratings in one of the two highest rating categories.

BBF’s VRDP Shares are senior in priority to BBF’s common shares as to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up of the affairs of such Fund. The VRDP Shares will rank on parity with other preferred shares of BBF as to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up of the affairs of BBF. The 1940 Act prohibits the declaration of any dividend on BBF’s common shares or the repurchase of BBF’s common shares if BBF fails to maintain the asset coverage of at least 200% of the liquidation preference of the outstanding VRDP Shares. In addition, pursuant to the VRDP Shares’ governing instruments, BBF is restricted from declaring and paying dividends on classes of shares ranking junior to or on parity with the VRDP Shares or repurchasing such shares if BBF fails to declare and pay dividends on the VRDP Shares, redeem any VRDP Shares required to be redeemed under the VRDP Shares’ governing instruments or comply with the basic maintenance amount requirement of the agencies rating the VRDP Shares.

The VRDP Holders have voting rights equal to BBF’s common shareholders (one vote per Share) and will vote together with such common shareholders (one vote per Share) as a single class. However, the VRDP Holders, voting as a separate class, are also entitled to elect two Board Members for BBF. In addition, the 1940 Act requires that along with approval by shareholders that might otherwise be required, the approval of a 1940 Act Majority of the VRDP Holders of BBF, voting separately as a class, would be required to (a) adopt any plan of reorganization that would adversely affect the VRDP Shares of BBF, (b) change BBF’s sub-classification as a closed-end management investment company or change its fundamental investment restrictions or (c) change its business so as to cease to be an investment company.

On October 22, 2015, BBF commenced a special rate period ending April 18, 2018 with respect to its VRDP Shares (the “Special Rate Period”). This Special Rate Period was extended and is currently set to expire on April 15, 2021. The VRDP Holders and BBF may mutually agree to extend the Special Rate Period prior to the expiration of the Special Rate Period. If the Special Rate Period is not extended, the VRDP Shares will revert to remarketable securities upon the termination of the Special Rate Period and will be remarketed and available for purchase by qualified institutional investors. The Liquidity Facility remains in effect for the duration of the Special Rate Period and the VRDP Shares are still subject to mandatory redemption by BBF on their respective mandatory redemption date. However, the VRDP Shares will not be remarketed or subject to optional or mandatory tender events during such time. The short-term ratings of the VRDP Shares were withdrawn by Moody’s, Fitch and/or S&P upon the commencement of the Special Rate Period. Short-term ratings may be re-assigned upon the termination of the Special Rate Period.

During the Special Rate Period, BBF is required to maintain the same asset coverage, basic maintenance amount and leverage requirements for the VRDP Shares as was required prior to the Special Rate Period.

During the Special Rate Period, BBF will pay no fees to the liquidity provider and remarketing agent, but will instead pay dividends monthly based on the sum of 0.75% of the one-month LIBOR Rate and a percentage per annum based on the long-term ratings assigned to the VRDP Shares. As of September 30, 2020, the BBF VRDP Shares were assigned long-term ratings of Aa2 from Moody’s and AAA from Fitch. The annualized dividend rate of the BBF VRDP Shares as of July 31, 2020 was as follows:

44

The Ratings Spread will increase in the event the VRDP Shares are rated below Aaa/AAA by all of the rating agencies rating the VRDP Shares at the time such Ratings Spread is determined, up to a maximum of 4.00% in the event the VRDP Shares are either rated below Baa3/BBB- by at least one of the rating agencies then rating the VRDP Shares or not rated by any rating agency.

Under BBF’s Fee Agreement with the liquidity provider, to the extent the liquidity provider together with certain affiliates individually or in the aggregate own at least 20% of the outstanding VRDP Shares and BBF has not failed to pay dividends on the VRDP Shares for two years, the liquidity provider agreed to enter into and maintain a voting trust agreement and convey into the voting trust the right to vote all of its VRDP Shares owned by it or such affiliates, with respect to: (i) the election of the two members of the Board for which VRDP Holders are entitled to vote under the 1940 Act and all other rights given to VRDP Holders with respect to the election of the Board; (ii) the conversion of BBF from a closed-end management investment company to an open-end fund, or to change BBF’s classification from diversified to non-diversified; (iii) the deviation from a policy in respect of concentration of investments in any particular industry or group of industries as recited in BBF’s registration statement; and (iv) borrowing money, issuing senior securities, underwriting securities issued by other persons, purchasing or selling real estate or commodities or making loans to other persons other than in accordance with the recitals of policy with respect thereto in BBF’s registration statement.

If the Special Rate Period is not extended, the VRDP Shares will revert back to remarketable securities and will be remarketed and available for purchase by qualified institutional investors. There is no assurance that the VRDP Shares will be remarketed or purchased by investors after the termination of the Special Rate Period. If the VRDP Shares are not remarketed or purchased, then a failed remarketing will occur. As described above, in the event of a failed remarketing, the dividend rate of the VRDP Shares will be reset to the maximum rate and the VRDP Shares that have not been remarketed are required to be purchased by the liquidity provider and subject to redemption by BBF after six months of continuous, unsuccessful remarketing.

RISK FACTORS AND SPECIAL CONSIDERATIONS

Comparison of Risks

Because of their similar investment objectives and similar investment strategies, each Fund is subject to similar investment risks. With respect to the differences in risks, those risks of BSD, MFT and/or BBF that are not shared with the Acquiring Fund are generally as a result of differences in the Funds’ principal investment strategies described above under “Summary—Investment Objective and Policies.”

Each Fund utilizes leverage through the issuance of either VMTP Shares or VRDP Shares and TOBs. See “The Acquiring Fund’s Investments—Leverage;” “General Risks of Investing in the Acquiring Fund—Leverage Risk;” and “General Risks of Investing in the Acquiring Fund—Tender Option Bond Risk.” Each of BSD, MFT and the Acquiring Fund currently leverages its assets through the use of VMTP Share and TOBs. BBF currently leverages its assets through the use of VRDP Shares and TOBs. The Acquiring Fund is expected to continue to leverage its assets after the Closing Date of the Reorganizations through the use of VMTP Shares and TOBs. Please see “Information about the Preferred Shares of the Funds” for additional information about the preferred shares of each Fund.

In the normal course of business, each Fund invests in securities and enters into transactions where risks exist due to fluctuations in the market (market risk) or failure of the issuer of a security to meet all its obligations (issuer credit risk). The value of securities held by the Funds may decline in response to certain events, including those directly involving the issuers whose securities are owned by the Funds; conditions affecting the general economy; overall market changes; pandemics, epidemics and other global health events; local, regional or global political, social or economic instability; and currency and interest rate and price fluctuations. Similar to issuer credit risk, the Funds may be exposed to counterparty credit risk, or the risk that an entity with which the Funds have unsettled or open transactions may fail to or be unable to perform on its commitments.

The Combined Fund will be managed in accordance with the same investment objective, investment strategies and investment policies, and subject to the same risks, as the Acquiring Fund. Risk is inherent in all investing. An investment in the Acquiring Fund should not be considered a complete investment program. Each shareholder should take into account the Acquiring Fund’s investment objective as well as the shareholder’s other investments when considering an investment in the Acquiring Fund. You may lose part or all of your investment in the Acquiring Fund or your investment may not perform as well as other similar investments.

BBF VRDP Shares will be subject to the same risks that currently apply to the Acquiring Fund VMTP Shares and will apply to the Acquiring Fund VMTP Shares, assuming the Acquiring Fund VRDP Refinancing is completed.

General Risks of Investing in the Acquiring Fund

Municipal Bond Market Risk. Economic exposure to the municipal securities market involves certain risks. The Acquiring Fund’s economic exposure to municipal securities includes municipal securities in the Acquiring Fund’s portfolio and municipal securities to which the Acquiring Fund is exposed through the ownership of residual interests in municipal TOBs (“TOB Residuals”). The municipal market is one in which dealer firms make markets in bonds on a principal basis using their proprietary capital, and during the financial crisis of 2007-2009 these firms’ capital was severely constrained. As a result, some firms were unwilling to commit their capital to purchase and to serve as a dealer for municipal securities. Certain municipal securities may not be registered with the SEC or any state securities commission and will not be listed on any national securities exchange. The amount of public information available about the municipal securities to which the Acquiring Fund is economically exposed is generally less than that for corporate equities or bonds, and the investment performance of the Acquiring Fund may therefore be more dependent on the analytical abilities of the Investment Advisor than would be a fund investing solely in stocks or taxable bonds. The secondary market for municipal

46

securities, particularly the below investment grade securities to which the Acquiring Fund may be economically exposed, also tends to be less well-developed or liquid than many other securities markets, which may adversely affect the Acquiring Fund’s ability to sell such securities at attractive prices or at prices approximating those at which the Acquiring Fund currently values them.

In addition, many state and municipal governments that issue securities are under significant economic and financial stress and may not be able to satisfy their obligations. The ability of municipal issuers to make timely payments of interest and principal may be diminished during general economic downturns and as governmental cost burdens are reallocated among federal, state and local governments. The taxing power of any governmental entity may be limited by provisions of state constitutions or laws and an entity’s credit will depend on many factors, including the entity’s tax base, the extent to which the entity relies on federal or state aid, and other factors which are beyond the entity’s control. In addition, laws enacted in the future by Congress or state legislatures or referenda could extend the time for payment of principal and/or interest, or impose other constraints on enforcement of such obligations or on the ability of municipalities to levy taxes. Issuers of municipal securities might seek protection under the bankruptcy laws. In the event of bankruptcy of such an issuer, holders of municipal securities could experience delays in collecting principal and interest and such holders may not, in all circumstances, be able to collect all principal and interest to which they are entitled. To enforce its rights in the event of a default in the payment of interest or repayment of principal, or both, the Acquiring Fund may take possession of and manage the assets securing the issuer’s obligations on such securities, which may increase the Acquiring Fund’s operating expenses. Any income derived from the Acquiring Fund’s ownership or operation of such assets may not be tax-exempt or may fail to generate qualifying income for purposes of the income tests applicable to regulated investment companies (“RICs”).

Taxable Municipal Securities Risk. Build America Bonds involve similar risks as municipal bonds, including credit and market risk. In particular, should a Build America Bond’s issuer fail to continue to meet the applicable requirements imposed on the bonds as provided by the American Recovery and Reinvestment Act (“ARRA”), it is possible that such issuer may not receive federal cash subsidy payments, impairing the issuer’s ability to make scheduled interest payments. The Build America Bond program expired on December 31, 2010 and no further issuance is permitted unless Congress renews the program. As a result, the number of available Build America Bonds is limited, which may negatively affect the value of the Build America Bonds. In addition, there can be no assurance that Build America Bonds will be actively traded. It is difficult to predict the extent to which a market for such bonds will continue, meaning that Build America Bonds may experience greater illiquidity than other municipal obligations. The Build America Bonds outstanding as of December 31, 2010 will continue to be eligible for the federal interest rate subsidy, which continues for the life of the Build America Bonds; however, no bonds issued following expiration of the Build America Bond program will be eligible for the U.S. federal tax subsidy.

Municipal Securities Risks. Municipal securities risks include the ability of the issuer to repay the obligation, the relative lack of information about certain issuers of municipal securities, and the possibility of future legislative changes which could affect the market for and the value of municipal securities. These risks include:

General Obligation Bonds Risks. General obligation bonds are typically secured by the issuer’s pledge of its faith, credit and taxing power for the repayment of principal and the payment of interest. The taxing power of any governmental entity may be limited, however, by provisions of its state constitution or laws, and an entity’s creditworthiness will depend on many factors, including potential erosion of its tax base due to population declines, natural disasters, declines in the state’s industrial base or inability to attract new industries, economic limits on the ability to tax without eroding the tax base, state legislative proposals or voter initiatives to limit ad valorem real property taxes and the extent to which the entity relies on federal or state aid, access to capital markets or other factors beyond the state’s or entity’s control. Accordingly, the capacity of the issuer of a general obligation bond as to the timely payment of interest and the repayment of principal when due is affected by the issuer’s maintenance of its tax base.

47

Revenue Bonds Risks. Revenue or special obligation bonds are typically payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue sources such as payments from the user of the facility being financed. Accordingly, the timely payment of interest and the repayment of principal in accordance with the terms of the revenue or special obligation bond is a function of the economic viability of such facility or such revenue source. Revenue bonds issued by state or local agencies to finance the development of low-income, multi-family housing involve special risks in addition to those associated with municipal securities generally, including that the underlying properties may not generate sufficient income to pay expenses and interest costs. Such bonds are generally non-recourse against the property owner, may be junior to the rights of others with an interest in the properties, may pay interest that changes based in part on the financial performance of the property, may be prepayable without penalty and may be used to finance the construction of housing developments which, until completed and rented, do not generate income to pay interest. Increases in interest rates payable on senior obligations may make it more difficult for issuers to meet payment obligations on subordinated bonds.

Private Activity Bonds Risks. The Acquiring Fund may invest in certain tax-exempt securities classified as “private activity bonds.” These bonds may subject certain investors in the Acquiring Fund to the federal alternative minimum tax.

Moral Obligation Bonds Risks. Municipal bonds may also include “moral obligation” bonds, which are normally issued by special purpose public authorities. If an issuer of moral obligation bonds is unable to meet its obligations, the repayment of such bonds becomes a moral commitment but not a legal obligation of the state or municipality in question.

Municipal Notes Risks. Municipal notes are shorter term municipal debt obligations. They may provide interim financing in anticipation of tax collection, bond sales or revenue receipts. If there is a shortfall in the anticipated proceeds, repayment on the note may be delayed or the note may not be fully repaid, and the Acquiring Fund may lose money.

Municipal Lease Obligations Risks. Also included within the general category of municipal bonds are certificates of participation (“COPs”) issued by government authorities or entities to finance the acquisition or construction of equipment, land and/or facilities. COPs represent participations in a lease, an installment purchase contract or a conditional sales contract (hereinafter collectively called “lease obligations”) relating to such equipment, land or facilities. Municipal leases, like other municipal debt obligations, are subject to the risk of non-payment. Although lease obligations do not constitute general obligations of the issuer for which the issuer’s unlimited taxing power is pledged, a lease obligation is frequently backed by the issuer’s covenant to budget for, appropriate and make the payments due under the lease obligation. However, certain lease obligations contain “non-appropriation” clauses which provide that the issuer has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. Although “non-appropriation” lease obligations are secured by the leased property, disposition of the property in the event of foreclosure might prove difficult and the value of the property may be insufficient to issue lease obligations. Certain investments in lease obligations may be illiquid.

The ability of issuers of municipal leases to make timely lease payments may be adversely impacted in general economic downturns and as relative governmental cost burdens are allocated and reallocated among federal, state and local governmental units. Such non-payment would result in a reduction of income to the Acquiring Fund, and could result in a reduction in the value of the municipal lease experiencing non-payment and a potential decrease in the NAV of the Acquiring Fund. Issuers of municipal lease obligations might seek protection under the bankruptcy laws. In the event of bankruptcy of such an issuer, the Acquiring Fund could experience delays and limitations with respect to the collection of principal and interest on such municipal leases and the Acquiring Fund may not, in all circumstances, be able to collect all principal and interest to which it is entitled. To enforce its rights in the event of a default in lease payments, the Acquiring Fund might take possession of and manage the assets securing the issuer’s obligations on such securities, which may increase the

48

Acquiring Fund’s operating expenses and adversely affect the NAV of the Acquiring Fund. When the lease contains a non-appropriation clause, however, the failure to pay would not be a default and the Acquiring Fund would not have the right to take possession of the assets. Any income derived from the Acquiring Fund’s ownership or operation of such assets may not be tax-exempt or may fail to generate qualifying income for purposes of the income tests applicable to regulated investment companies. In addition, the Acquiring Fund’s intention to qualify as a regulated investment company under the Code, may limit the extent to which the Acquiring Fund may exercise its rights by taking possession of such assets, because as a regulated investment company the Acquiring Fund is subject to certain limitations on its investments and on the nature of its income.

Liquidity of Investments. Certain municipal securities in which the Acquiring Fund invests may lack an established secondary trading market or are otherwise considered illiquid. Liquidity of a security relates to the ability to easily dispose of the security and the price to be obtained and does not generally relate to the credit risk or likelihood of receipt of cash at maturity. Illiquid securities may trade at a discount from comparable, more liquid investments.

The financial markets in general, and certain segments of the municipal securities markets in particular, have in recent years experienced periods of extreme secondary market supply and demand imbalance, resulting in a loss of liquidity during which market prices were suddenly and substantially below traditional measures of intrinsic value. During such periods some securities could be sold only at arbitrary prices and with substantial losses. Periods of such market dislocation may occur again at any time.

Tax-Exempt Status Risk. In making investments, the Acquiring Fund and the Investment Advisor will rely on the opinion of issuers’ bond counsel and, in the case of derivative securities, sponsors’ counsel, on the tax-exempt status of interest on municipal obligations and payments under tax-exempt derivative securities. Neither the Acquiring Fund nor the Investment Advisor will independently review the bases for those tax opinions. If any of those tax opinions are ultimately determined to be incorrect or if events occur after the security is acquired that impact the security’s tax-exempt status, the Acquiring Fund and its shareholders could be subject to substantial tax liabilities. An assertion by the Internal Revenue Service (the “IRS”) that a portfolio security is not exempt from U.S. federal income tax (contrary to indications from the issuer) could affect the Acquiring Fund’s and its shareholders’ income tax liability for the current or past years and could create liability for information reporting penalties. In addition, an IRS assertion of taxability may cause the Acquiring Fund to be ineligible to pay exempt-interest dividends or may impair the liquidity and the fair market value of the securities.

Taxability Risk. The Acquiring Fund intends to minimize the payment of taxable income to shareholders by investing in tax-exempt or municipal securities in reliance at the time of purchase on an opinion of bond counsel to the issuer that the interest paid on those securities will be excludable from gross income for U.S. federal income tax purposes. Such securities, however, may be determined to pay, or have paid, taxable income subsequent to the Acquiring Fund’s acquisition of the securities. In that event, the IRS may demand that the Acquiring Fund pay U.S. federal income taxes on the affected interest income, and, if the Acquiring Fund agrees to do so, the Acquiring Fund’s yield could be adversely affected. In addition, the treatment of dividends previously paid or to be paid by the Acquiring Fund as “exempt interest dividends” could be adversely affected, subjecting the Acquiring Fund’s shareholders to increased U.S. federal income tax liabilities. In addition, future laws, regulations, rulings or court decisions may cause interest on municipal securities to be subject, directly or indirectly, to U.S. federal income taxation or interest on state municipal securities to be subject to state or local income taxation, or the value of state municipal securities to be subject to state or local intangible personal property tax, or may otherwise prevent the Acquiring Fund from realizing the full current benefit of the tax-exempt status of such securities. Any such change could also affect the market price of such securities, and thus the value of an investment in the Acquiring Fund.

Alternative Minimum Tax Risk. The Acquiring Fund expects that a portion of the interest or income it produces will be includable in alternative minimum taxable income. Exempt interest dividends also are likely to

49

be subject to state and local income taxes. Distributions of any capital gain or other taxable income will be taxable to shareholders. The Acquiring Fund may not be a suitable investment for investors who are subject to the federal alternative minimum tax or who would become subject to such tax by purchasing shares of the Acquiring Fund. The suitability of an investment in the Acquiring Fund will depend upon a comparison of the after tax yield likely to be provided from the Acquiring Fund with that from comparable tax-exempt investments not subject to the alternative minimum tax, and from comparable fully taxable investments, in light of each such investor’s tax position. Special considerations apply to corporate investors.

Nonpayment Risk. Municipal bonds, like other debt obligations, are subject to the risk of nonpayment. The ability of issuers of municipal securities to make timely payments of interest and principal may be adversely impacted in general economic downturns and as relative governmental cost burdens are allocated and reallocated among federal, state and local governmental units. Such nonpayment would result in a reduction of income to the Acquiring Fund and could result in a reduction in the value of the municipal security experiencing nonpayment and a potential decrease in the net asset value of the Acquiring Fund.

Fixed Income Securities Risks. Fixed income securities in which the Acquiring Fund may invest are generally subject to the following risks:

Interest Rate Risk. The market value of bonds and other fixed-income securities changes in response to interest rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. The Acquiring Fund may be subject to a greater risk of rising interest rates due to the current period of historically low interest rates, including the Federal Reserve’s recent lowering of the target for the federal funds rate to a range of 0%-0.25% as part of its efforts to ease the economic effects of the coronavirus pandemic. The magnitude of these fluctuations in the market price of bonds and other fixed- income securities is generally greater for those securities with longer maturities. Fluctuations in the market price of the Acquiring Fund’s investments will not affect interest income derived from instruments already owned by the Acquiring Fund, but will be reflected in the Acquiring Fund’s NAV. The Acquiring Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by the Acquiring Fund’s management. To the extent the Acquiring Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-related securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of the Acquiring Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the NAV of the Acquiring Fund to the extent that it invests in floating rate debt securities. These basic principles of bond prices also apply to U.S. Government securities. A security backed by the “full faith and credit” of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in value when interest rates change.

The Acquiring Fund’s use of leverage, as described below, will tend to increase the Acquiring Fund’s interest rate risk. The Acquiring Fund may utilize certain strategies, including taking positions in futures or interest rate swaps, for the purpose of reducing the interest rate sensitivity of fixed income securities held by the Acquiring Fund and decreasing the Acquiring Fund’s exposure to interest rate risk. The Acquiring Fund is not required to hedge its exposure to interest rate risk and may choose not to do so. In addition, there is no assurance that any attempts by the Acquiring Fund to reduce interest rate risk will be successful or that any hedges that the Acquiring Fund may establish will perfectly correlate with movements in interest rates.

The Acquiring Fund may invest in variable and floating rate debt instruments, which generally are less sensitive to interest rate changes than longer duration fixed rate instruments, but may decline in value in response to rising interest rates if, for example, the rates at which they pay interest do not rise as much, or as quickly, as market interest rates in general. Conversely, variable and floating rate instruments generally will not increase in value if interest rates decline. The Acquiring Fund also may invest in inverse floating rate debt securities, which

50

may decrease in value if interest rates increase, and which also may exhibit greater price volatility than fixed rate debt obligations with similar credit quality.

Issuer Risk. The value of fixed income securities may decline for a number of reasons which directly relate to the issuer, such as management performance, financial leverage, reduced demand for the issuer’s goods and services, historical and prospective earnings of the issuer and the value of the assets of the issuer.

Credit Risk. Credit risk is the risk that one or more fixed income securities in the Acquiring Fund’s portfolio will decline in price or fail to pay interest or principal when due because the issuer of the security experiences a decline in its financial status. Credit risk is increased when a portfolio security is downgraded or the perceived creditworthiness of the issuer deteriorates. To the extent the Acquiring Fund invests in below investment grade securities, it will be exposed to a greater amount of credit risk than a fund which only invests in investment grade securities. In addition, to the extent the Acquiring Fund uses credit derivatives, such use will expose it to additional risk in the event that the bonds underlying the derivatives default. The degree of credit risk depends on the issuer’s financial condition and on the terms of the securities. If rating agencies lower their ratings of municipal securities in the Acquiring Fund’s portfolio, the value of those securities could decline, which could jeopardize rating agencies’ ratings of Acquiring Fund VMTP Shares. Because a significant source of income for the Acquiring Fund is the interest and principal payments on the municipal securities in which it invests, any default by an issuer of a municipal security could have a negative impact on the Acquiring Fund’s ability to pay dividends on common shares or any VMTP Shares then outstanding and could result in the redemption of some or all of any VMTP Shares then outstanding.

Prepayment Risk. During periods of declining interest rates, borrowers may exercise their option to prepay principal earlier than scheduled. For fixed rate securities, such payments often occur during periods of declining interest rates, forcing the Acquiring Fund to reinvest in lower yielding securities, resulting in a possible decline in the Acquiring Fund’s income and distributions to shareholders. This is known as prepayment or “call” risk. Below investment grade securities frequently have call features that allow the issuer to redeem the security at dates prior to its stated maturity at a specified price (typically greater than par) only if certain prescribed conditions are met (“call protection”). For premium bonds (bonds acquired at prices that exceed their par or principal value) purchased by the Acquiring Fund, prepayment risk may be enhanced.

Reinvestment Risk. Reinvestment risk is the risk that income from the Acquiring Fund’s portfolio will decline if the Acquiring Fund invests the proceeds from matured, traded or called fixed income securities at market interest rates that are below the Acquiring Fund portfolio’s current earnings rate.

Duration and Maturity Risk. The Investment Advisor may seek to adjust the portfolio’s duration or maturity based on its assessment of current and projected market conditions and all factors that the Investment Advisor deems relevant. In comparison to maturity (which is the date on which the issuer of a debt instrument is obligated to repay the principal amount), duration is a measure of the price volatility of a debt instrument as a result in changes in market rates of interest, based on the weighted average timing of the instrument’s expected principal and interest payments. Specifically, duration measures the anticipated percentage change in NAV that is expected for every percentage point change in interest rates. The two have an inverse relationship. Duration can be a useful tool to estimate anticipated price changes to a fixed pool of income securities associated with changes in interest rates. For example, a duration of five years means that a 1% decrease in interest rates will increase the NAV of the portfolio by approximately 5%; if interest rates increase by 1%, the NAV will decrease by 5%. However, in a managed portfolio of fixed income securities having differing interest or dividend rates or payment schedules, maturities, redemption provisions, call or prepayment provisions and credit qualities, actual price changes in response to changes in interest rates may differ significantly from a duration-based estimate at any given time. Actual price movements experienced by a portfolio of fixed income securities will be affected by how interest rates move (i.e., changes in the relationship of long-term interest rates to short-term interest rates and in the relationship of interest rates for highly rated securities and rates for below investment grade securities), the magnitude of any move in interest rates, actual and anticipated prepayments of principal through call or

51

redemption features, the extension of maturities through restructuring, the sale of securities for portfolio management purposes, the reinvestment of proceeds from prepayments on and from sales of securities, and credit quality-related considerations whether associated with financing costs to lower credit quality borrowers or otherwise, as well as other factors. Accordingly, while duration maybe a useful tool to estimate potential price movements in relation to changes in interest rates, investors are cautioned that duration alone will not predict actual changes in the net asset or market value of the Acquiring Fund’s shares and that actual price movements in the Acquiring Fund’s portfolio may differ significantly from duration-based estimates. Duration differs from maturity in that it takes into account a security’s yield, coupon payments and its principal payments in addition to the amount of time until the security finally matures. As the value of a security changes over time, so will its duration. Prices of securities with longer durations tend to be more sensitive to interest rate changes than securities with shorter durations. In general, a portfolio of securities with a longer duration can be expected to be more sensitive to interest rate changes than a portfolio with a shorter duration. Any decisions as to the targeted duration or maturity of any particular category of investments or of the Acquiring Fund’s portfolio generally will be made based on all pertinent market factors at any given time. The Acquiring Fund may incur costs in seeking to adjust the portfolio’s average duration or maturity. There can be no assurances that the Investment Advisor’s assessment of current and projected market conditions will be correct or that any strategy to adjust the portfolio’s duration or maturity will be successful at any given time.

Leverage Risk. The use of leverage creates an opportunity for increased common share net investment income dividends, but also creates risks for the common shareholders. The Acquiring Fund cannot assure you that the use of leverage, if employed, will result in a higher yield on the common shares. Any leveraging strategy the Acquiring Fund employs may not be successful. Leverage involves risks and special considerations for common shareholders, including:

Any decline in the NAV of the Acquiring Fund’s investments will be borne entirely by the common shareholders. Therefore, if the market value of the Acquiring Fund’s portfolio declines, leverage will result in a greater decrease in NAV to the common shareholders than if the Acquiring Fund were not leveraged. This greater NAV decrease will also tend to cause a greater decline in the market price for the common shares. Changes in the future direction of interest rates are very difficult to predict accurately. If the Acquiring Fund were to reduce any outstanding leverage based on a prediction about future changes to interest rates, and that prediction turned out to be incorrect, the reduction in any outstanding leverage would likely operate to reduce the income and/or total returns to common shareholders relative to the circumstance where the Acquiring Fund had not reduced any of its outstanding leverage. The Acquiring Fund may decide that this risk outweighs the likelihood of achieving the desired reduction to volatility in income and share price if the prediction were to turn out to be correct, and determine not to reduce any of its outstanding leverage as described above.

The Acquiring Fund currently utilizes leverage through the issuance of VMTP Shares (see “Information about the Preferred Shares of the Funds”) and investments in TOB Residuals (see “—Tender Option Bond Risk”). The use of TOB Residuals may require the Acquiring Fund to segregate or designate on its books and

52

records assets to cover its obligations. While the segregated or earmarked assets may be invested in liquid assets, they may not be used for other operational purposes. Consequently, the use of leverage may limit the Acquiring Fund’s flexibility and may require that the Acquiring Fund sell other portfolio investments to pay Fund expenses, to maintain assets in an amount sufficient to cover the Acquiring Fund’s leveraged exposure or to meet other obligations at a time when it may be disadvantageous to sell such assets.

Certain types of leverage used by the Acquiring Fund may result in the Acquiring Fund being subject to covenants relating to asset coverage and portfolio composition requirements. The Acquiring Fund may be subject to certain restrictions on investments imposed by guidelines of one or more rating agencies, which issue ratings for the VMTP Shares issued by the Acquiring Fund or the governing instrument for the Acquiring Fund VMTP Shares. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed by the 1940 Act. The Investment Advisor does not believe that these covenants or guidelines will impede it from managing the Acquiring Fund’s portfolio in accordance with the Acquiring Fund’s investment objective and policies.

While there are any preferred shares of the Acquiring Fund outstanding, the Acquiring Fund may not declare any cash dividend or other distribution on its common shares, unless at the time of such declaration, (i) all accrued preferred shares dividends have been paid and (ii) the value of the Acquiring Fund’s total assets (determined after deducting the amount of such dividend or other distribution), less all liabilities and indebtedness of the Acquiring Fund, is at least 200% (as required by the 1940 Act) of the liquidation preference of the outstanding preferred shares (expected to equal the aggregate original purchase price of the outstanding preferred shares plus any accrued and unpaid dividends thereon, whether or not earned or declared on a cumulative basis). This limitation on the Acquiring Fund’s ability to make distributions on its common shares could in certain circumstances impair the ability of the Acquiring Fund to maintain its qualification for taxation as a regulated investment company under the Code. The Acquiring Fund may, however, to the extent possible, purchase or redeem preferred shares from time to time to maintain compliance with such asset coverage requirements and may pay special dividends to the holders of the preferred shares in certain circumstances in connection with any such impairment of the Acquiring Fund’s status as a regulated investment company under the Code.

In addition to the foregoing, the use of leverage treated as indebtedness of the Acquiring Fund for U.S. federal income tax purposes may reduce the amount of Acquiring Fund dividends that are otherwise eligible for the dividends received deduction in the hands of corporate shareholders.

The Acquiring Fund may utilize leverage through investment derivatives. The use of certain derivatives will require the Acquiring to segregate assets to cover its obligations. While the segregated assets may be invested in liquid assets, they may not be used for other operational purposes. Consequently, the use of leverage may limit the Acquiring Fund’s flexibility and may require that the Acquiring Fund sell other portfolio investments to pay Acquiring Fund expenses, to maintain assets in an amount sufficient to cover the Acquiring Fund’s leveraged exposure or to meet other obligations at a time when it may be disadvantageous to sell such assets.

The Acquiring Fund may invest in the securities of other investment companies. Such investment companies may also be leveraged, and will therefore be subject to the leverage risks described above. This additional leverage may in certain market conditions reduce the NAV of the Acquiring Fund’s common shares and the returns to the common shareholders.

Tender Option Bond Risk. The Acquiring Fund currently leverages its assets through the use of TOB Residuals, which are derivative interests in municipal bonds. The TOB Residuals in which the Acquiring Fund may invest pay interest or income that, in the opinion of counsel to the issuer of such TOB Residuals, is exempt from regular U.S. federal income tax. No independent investigation will be made to confirm the tax-exempt status of the interest or income paid by TOB Residuals held by the Acquiring Fund. There is no assurance that the Acquiring Fund’s strategy of using TOB Residuals to leverage its assets will be successful.

53

TOB Residuals represent beneficial interests in a special purpose trust formed for the purpose of holding municipal bonds contributed by one or more funds (a “TOB Trust”). A TOB Trust typically issues two classes of beneficial interests: short-term floating rate interests (“TOB Floaters”), which are sold to third-party investors, and TOB Residuals, which are generally issued to the fund(s) that transferred municipal bonds to the TOB Trust. TOB Floaters may have first priority on the cash flow from the municipal bonds held by the TOB Trust and are enhanced with a liquidity support arrangement provided by a third-party bank or other financial institution (the “TOBs Liquidity Provider”) which allows holders to tender their position at par (plus accrued interest). The Acquiring Fund, as a holder of TOB Residuals, is paid the residual cash flow from the TOB Trust. As result, distributions on TOB Residuals will bear an inverse relationship to short-term municipal bond interest rates. Distributions on the TOB Residuals paid to the Acquiring Fund will be reduced or, in the extreme, eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. The amount of such reduction or increase is a function, in part, of the amount of TOB Floaters sold by the TOB Trust relative to the amount of the TOB Residuals that it sells. The greater the amount of TOB Floaters sold relative to the TOB Residuals, the more volatile the distributions on the TOB Residuals will be. Short-term interest rates are at historic lows and may be more likely to rise in the current market environment.

The municipal bonds transferred to a TOB Trust typically are high grade municipal bonds. In certain cases, when municipal bonds transferred are lower grade municipal bonds, the TOB Trust transaction includes a credit enhancement feature that provides for the timely payment of principal and interest on the bonds to the TOB Trust by a credit enhancement provider. The TOB Trust would be responsible for the payment of the credit enhancement fee and the Acquiring Fund, as a TOB Residual holder, would be responsible for reimbursement of any payments of principal and interest made by the credit enhancement provider.

Any economic leverage achieved through the Acquiring Fund’s investment in TOB Residuals will increase the possibility that common share long-term returns will be diminished if the cost of the TOB Floaters issued by a TOB Trust exceeds the return on the securities in the TOB Trust. If the income and gains earned on municipal securities owned by a TOB Trust that issues TOB Residuals to the Acquiring Fund are greater than the payments due on the TOB Floaters issued by the TOB Trust, the Acquiring Fund’s returns will be greater than if it had not invested in the TOB Residuals.

Although the Acquiring Fund generally would unwind a TOB transaction rather than try to sell a TOB Residual, if it did try to sell a TOB Residual, its ability to do so would depend on the liquidity of the TOB Residual. TOB Residuals have varying degrees of liquidity based, among other things, upon the liquidity of the underlying securities deposited in the TOB Trust. The market price of TOB Residuals is more volatile than the underlying municipal bonds due to leverage.

The leverage attributable to the Acquiring Fund’s use of TOB Residuals may be “called away” on relatively short notice and therefore may be less permanent than more traditional forms of leverage. The TOB Trust may be collapsed without the consent of the Acquiring Fund upon the occurrence of termination events, as defined in the TOB Trust agreements. Upon the occurrence of a termination event, a TOB Trust would be liquidated with the proceeds applied first to any accrued fees owed to the trustee of the TOB Trust, the remarketing agent of the TOB Floaters and the TOBs Liquidity Provider. Upon certain termination events, the holders of the TOB Floaters would be paid before the TOB Residual holders (i.e., the Acquiring Fund) whereas in other termination events, the holders of TOB Floaters and the TOB Residual holders would be paid pro rata.

The Acquiring Fund may invest in a TOB Trust on either a non-recourse or recourse basis. If the Acquiring Fund invests in a TOB Trust on a recourse basis, it will typically enter into a reimbursement agreement with the TOBs Liquidity Provider pursuant to which the Acquiring Fund is required to reimburse the TOBs Liquidity Provider the balance, if any, of the amount owed under the liquidity facility over the liquidation proceeds (the “Liquidation Shortfall”). As a result, if the Acquiring Fund invests in a recourse TOB Trust, the Acquiring Fund will bear the risk of loss with respect to any Liquidation Shortfall.

54

The use of TOB Residuals will require the Acquiring Fund to earmark or segregate liquid assets in an amount equal to any TOB Floaters, plus any accrued but unpaid interest due on the TOB Floaters, issued by TOB Trusts sponsored by, or on behalf of, the Acquiring Fund that are not owned by the Acquiring Fund. The use of TOB Residuals may also require the Acquiring Fund to earmark or segregate liquid assets in an amount equal to loans provided by the TOBs Liquidity Provider to the TOB Trust to purchase tendered TOB Floaters. While the segregated assets may be invested in liquid securities, they may not be used for other operational purposes. Consequently, the use of leverage through TOB Residuals may limit the Acquiring Fund’s flexibility and may require that the Acquiring Fund sell other portfolio investments to pay the Acquiring Fund’s expenses, to maintain assets in an amount sufficient to cover the Acquiring Fund’s leveraged exposure or to meet other obligations at a time when it may be disadvantageous to sell such assets. Future regulatory requirements or SEC guidance may necessitate more onerous contractual or regulatory requirements, which may increase the costs or reduce the degree of potential economic benefits of TOB Trust transactions or limit the Acquiring Fund’s ability to enter into or manage TOB Trust transactions.

The Acquiring Fund structures and “sponsors” the TOB Trusts in which it holds TOB Residuals and has certain duties and responsibilities, which may give rise to certain additional risks including, but not limited to, compliance, securities law and operational risks.

The SEC and various federal banking and housing agencies adopted credit risk retention rules for securitizations (the “Risk Retention Rules”). The Risk Retention Rules require the sponsor of a TOB Trust to retain at least 5% of the credit risk of the underlying assets supporting the TOB Trust’s municipal bonds. The Risk Retention Rules may adversely affect the Acquiring Fund’s ability to engage in TOB Trust transactions or increase the costs of such transactions in certain circumstances.

TOB Trusts constitute an important component of the municipal bond market. Any modifications or changes to the rules governing TOB Trusts may adversely impact the municipal market and the Acquiring Fund, including through reduced demand for and liquidity of municipal bonds and increased financing costs for municipal issuers. The ultimate impact of any potential modifications on the TOB market and the overall municipal market is not yet certain.

Insurance Risk. With respect to an insured municipal security, insurance guarantees that interest payments on the municipal security will be made on time and that the principal will be repaid when the security matures. Insurance is expected to protect the Acquiring Fund against losses caused by a municipal security issuer’s failure to make interest and principal payments. However, insurance does not protect the Acquiring Fund or its shareholders against losses caused by declines in a municipal security’s value. Also, the Acquiring Fund cannot be certain that any insurance company will make the payments it guarantees. Certain significant providers of insurance for municipal securities incurred significant losses as a result of exposure to sub-prime mortgages and other lower credit quality investments that experienced defaults or otherwise suffered extreme credit deterioration during the financial crisis of 2007-2009. These losses have reduced the insurers’ capital and called into question their continued ability to perform their obligations under such insurance if they are called upon to do so in the future. While an insured municipal security will typically be deemed to have the rating of its insurer, if the insurer of a municipal security suffers a downgrade in its credit rating or the market discounts the value of the insurance provided by the insurer, the rating of the underlying municipal security will be more relevant and the value of the municipal security would more closely, if not entirely, reflect such rating. The Acquiring Fund may lose money on its investment if the insurance company does not make payments it guarantees. If a municipal security’s insurer fails to fulfill its obligations or loses its credit rating, the value of the security could drop.

Yield and Ratings Risk. The yields on debt obligations are dependent on a variety of factors, including general market conditions, conditions in the particular market for the obligation, the financial condition of the

55

issuer, the size of the offering, the maturity of the obligation and the ratings of the issue. The ratings of Moody’s, S&P and Fitch, which are described in Appendix D, represent their respective opinions as to the quality of the obligations which they undertake to rate. Ratings, however, are general and are not absolute standards of quality. Consequently, obligations with the same rating, maturity and interest rate may have different market prices. Subsequent to its purchase by the Acquiring Fund, a rated security may cease to be rated. The Investment Advisor will consider such an event in determining whether the Acquiring Fund should continue to hold the security.

Ratings are relative and subjective and, although ratings may be useful in evaluating the safety of interest and principal payments, they do not evaluate the market value risk of such obligations. Although these ratings may be an initial criterion for selection of portfolio investments, the Investment Advisor also will independently evaluate these securities and the ability of the issuers of such securities to pay interest and principal. To the extent that the Acquiring Fund invests in lower grade securities that have not been rated by a rating agency, the Acquiring Fund’s ability to achieve its investment objective will be more dependent on the Investment Advisor’s credit analysis than would be the case when the Acquiring Fund invests in rated securities.

“High Yield” Securities Risk. Subject to its investment policies, the Acquiring Fund may invest in securities rated, at the time of investment, below investment grade quality such as those rated Ba or below by Moody’s, BB or below by S&P or Fitch, or securities comparably rated by other rating agencies or in unrated securities determined by the Investment Advisor to be of comparable quality. Such securities, sometimes referred to as “high yield” or “junk” bonds, are predominantly speculative with respect to the capacity to pay interest and repay principal in accordance with the terms of the security and generally involve greater price volatility than securities in higher rating categories. Often the protection of interest and principal payments with respect to such securities may be very moderate and issuers of such securities face major ongoing uncertainties or exposure to adverse business, financial or economic conditions which could lead to inadequate capacity to meet timely interest and principal payments.

Lower grade securities, though high yielding, are characterized by high risk. They may be subject to certain risks with respect to the issuing entity and to greater market fluctuations than certain lower yielding, higher rated securities. The secondary market for lower grade securities may be less liquid than that of higher rated securities. Adverse conditions could make it difficult at times for the Acquiring Fund to sell certain securities or could result in lower prices than those used in calculating the Acquiring Fund’s NAV.

The prices of fixed-income securities generally are inversely related to interest rate changes; however, the price volatility caused by fluctuating interest rates of securities also is inversely related to the coupons of such securities. Accordingly, below investment grade securities may be relatively less sensitive to interest rate changes than higher quality securities of comparable maturity because of their higher coupon. The investor receives this higher coupon in return for bearing greater credit risk. The higher credit risk associated with below investment grade securities potentially can have a greater effect on the value of such securities than may be the case with higher quality issues of comparable maturity.

Lower grade securities may be particularly susceptible to economic downturns. It is likely that an economic recession could severely disrupt the market for such securities and may have an adverse impact on the value of such securities. In addition, it is likely that any such economic downturn could adversely affect the ability of the issuers of such securities to repay principal and pay interest thereon and increase the incidence of default for such securities. The ratings of Moody’s, S&P, Fitch and other rating agencies represent their opinions as to the quality of the obligations which they undertake to rate. Ratings are relative and subjective and, although ratings may be useful in evaluating the safety of interest and principal payments, they do not evaluate the market value risk of such obligations. Although these ratings may be an initial criterion for selection of portfolio investments, the Investment Advisor also will independently evaluate these securities and the ability of the issuers of such securities to pay interest and principal. To the extent that the Acquiring Fund invests in lower grade securities that have not been rated by a rating agency, the Acquiring Fund’s ability to achieve its investment objective will

56

be more dependent on the Investment Advisor’s credit analysis than would be the case when the Acquiring Fund invests in rated securities.

Unrated Securities Risk. Because the Acquiring Fund may purchase securities that are not rated by any rating organization, the Investment Advisor may, after assessing their credit quality, internally assign ratings to certain of those securities in categories similar to those of rating organizations. Some unrated securities may not have an active trading market or may be difficult to value, which means the Acquiring Fund might have difficulty selling them promptly at an acceptable price. To the extent that the Acquiring Fund invests in unrated securities, the Acquiring Fund’s ability to achieve its investment objective will be more dependent on the Investment Advisor’s credit analysis than would be the case when the Acquiring Fund invests in rated securities.

Zero-Coupon Securities Risk. Municipal bonds may include zero-coupon bonds. Zero-coupon securities are bonds that are sold at a discount to par value and do not pay interest during the life of the security. The discount approximates the total amount of interest the security will accrue and compound over the period until maturity at a rate of interest reflecting the market rate of the security at the time of issuance. Upon maturity, the holder of a zero-coupon security is entitled to receive the par value of the security.

While interest payments are not made on zero-coupon securities, holders of such securities are deemed to have received income (“phantom income”) annually, notwithstanding that cash may not be received currently. The effect of owning instruments that do not make current interest payments is that a fixed yield is earned not only on the original investment but also, in effect, on all discount accretion during the life of the obligations. This implicit reinvestment of earnings at a fixed rate eliminates the risk of being unable to invest distributions at a rate as high as the implicit yield on the zero-coupon bond, but at the same time eliminates the holder’s ability to reinvest at higher rates in the future. For this reason, some of these securities may be subject to substantially greater price fluctuations during periods of changing market interest rates than are comparable securities that pay interest currently. Longer term zero-coupon bonds are more exposed to interest rate risk than shorter term zero-coupon bonds. These investments benefit the issuer by mitigating its need for cash to meet debt service, but also require a higher rate of return to attract investors who are willing to defer receipt of cash.

The Acquiring Fund accrues income with respect to these securities for U.S. federal income tax and accounting purposes prior to the receipt of cash payments. Zero-coupon securities may be subject to greater fluctuation in value and less liquidity in the event of adverse market conditions than comparably rated securities that pay cash interest at regular intervals.

Further, to maintain its qualification for pass-through treatment under the federal tax laws, the Acquiring Fund is required to distribute income to its shareholders and, consequently, may have to dispose of other, more liquid portfolio securities under disadvantageous circumstances or may have to leverage itself by borrowing in order to generate the cash to satisfy these distributions. The required distributions may result in an increase in the Acquiring Fund’s exposure to zero-coupon securities.

In addition to the above-described risks, there are certain other risks related to investing in zero-coupon securities. During a period of severe market conditions, the market for such securities may become even less liquid. In addition, as these securities do not pay cash interest, the Acquiring Fund’s investment exposure to these securities and their risks, including credit risk, will increase during the time these securities are held in the Acquiring Fund’s portfolio.

Variable Rate Demand Obligations Risk. Variable rate demand obligations (“VRDOs”) are floating rate securities that combine an interest in a long-term municipal bond with a right to demand payment before maturity from a bank or other financial institution. If the bank or financial institution is unable to pay, the Acquiring Fund may lose money.

Indexed and Inverse Securities Risk. Investments in inverse floaters, residual interest TOBs and similar instruments expose the Acquiring Fund to the same risks as investments in fixed income securities and

57

derivatives, as well as other risks, including those associated with leverage and increased volatility. An investment in these securities typically will involve greater risk than an investment in a fixed rate security. Distributions on inverse floaters, residual interest TOBs and similar instruments will typically bear an inverse relationship to short-term interest rates and typically will be reduced or, potentially, eliminated as interest rates rise. Inverse floaters, residual interest TOBs and similar instruments will underperform the market for fixed rate securities in a rising interest rate environment. Inverse floaters may be considered to be leveraged to the extent that their interest rates vary by a magnitude that exceeds the magnitude of the change in a reference rate of interest (typically a short-term interest rate). The leverage inherent in inverse floaters is associated with greater volatility in their market values. Investments in inverse floaters, residual interest TOBs and similar instruments that have fixed income securities underlying them will expose the Acquiring Fund to the risks associated with those fixed income securities and the values of those investments may be especially sensitive to changes in prepayment rates on the underlying fixed income securities.

When-Issued, Forward Commitment and Delayed Delivery Transactions Risk. The Acquiring Fund may purchase securities on a when-issued basis (including on a forward commitment or “TBA” (to be announced) basis) and may purchase or sell those securities for delayed delivery. When-issued and delayed delivery transactions occur when securities are purchased or sold by the Acquiring Fund with payment and delivery taking place in the future to secure an advantageous yield or price. Securities purchased on a when-issued or delayed delivery basis may expose the Acquiring Fund to counterparty risk of default as well as the risk that securities may experience fluctuations in value prior to their actual delivery. The Acquiring Fund will not accrue income with respect to a when-issued or delayed delivery security prior to its stated delivery date. Purchasing securities on a when-issued or delayed delivery basis can involve the additional risk that the price or yield available in the market when the delivery takes place may not be as favorable as that obtained in the transaction itself.

Repurchase Agreements Risk. Repurchase agreements typically involve the acquisition by the Acquiring Fund of fixed income securities from a selling financial institution such as a bank, savings and loan association or broker-dealer. The agreement provides that the Acquiring Fund will sell the securities back to the institution at a fixed time in the future. The Acquiring Fund does not bear the risk of a decline in the value of the underlying security unless the seller defaults under its repurchase obligation. In the event of the bankruptcy or other default of a seller of a repurchase agreement, the Acquiring Fund could experience both delays in liquidating the underlying securities and losses, including possible decline in the value of the underlying security during the period in which the Acquiring Fund seeks to enforce its rights thereto; possible lack of access to income on the underlying security during this period; and expenses of enforcing its rights. While repurchase agreements involve certain risks not associated with direct investments in fixed income securities, the Acquiring Fund follows procedures approved by the Board that are designed to minimize such risks. The value of the collateral underlying the repurchase agreement will be at least equal to the repurchase price, including any accrued interest earned on the repurchase agreement. In the event of a default or bankruptcy by a selling financial institution, the Acquiring Fund generally will seek to liquidate such collateral. However, the exercise of the Acquiring Fund’s right to liquidate such collateral could involve certain costs or delays and, to the extent that proceeds from any sale upon a default of the obligation to repurchase were less than the repurchase price, the Acquiring Fund could suffer a loss.

Reverse Repurchase Agreements Risk. Reverse repurchase agreements involve the risks that the interest income earned on the investment of the proceeds will be less than the interest expense of the Acquiring Fund, that the market value of the securities sold by the Acquiring Fund may decline below the price at which the Acquiring Fund is obligated to repurchase the securities and that the securities may not be returned to the Acquiring Fund. There is no assurance that reverse repurchase agreements can be successfully employed.

Securities Lending Risk. The Acquiring Fund may lend securities to financial institutions. Securities lending involves exposure to certain risks, including operational risk (i.e., the risk of losses resulting from problems in the settlement and accounting process), “gap” risk (i.e., the risk of a mismatch between the return on cash collateral reinvestments and the fees the Acquiring Fund has agreed to pay a borrower), and credit, legal,

58

counterparty and market risk. If a securities lending counterparty were to default, the Acquiring Fund would be subject to the risk of a possible delay in receiving collateral or in recovering the loaned securities, or to a possible loss of rights in the collateral. In the event a borrower does not return the Acquiring Fund’s securities as agreed, the Acquiring Fund may experience losses if the proceeds received from liquidating the collateral do not at least equal the value of the loaned security at the time the collateral is liquidated, plus the transaction costs incurred in purchasing replacement securities. This event could trigger adverse tax consequences for the Acquiring Fund. The Acquiring Fund could lose money if its short-term investment of the collateral declines in value over the period of the loan. Substitute payments for dividends received by the Acquiring Fund for securities loaned out by the Acquiring Fund will generally not be considered qualified dividend income. The securities lending agent will take the tax effects on shareholders of this difference into account in connection with the Acquiring Fund’s securities lending program. Substitute payments received on tax-exempt securities loaned out will generally not be tax-exempt income.

Restricted and Illiquid Securities Risk. The Acquiring Fund may invest in illiquid or less liquid investments or investments in which no secondary market is readily available or which are otherwise illiquid, including private placement securities. The Acquiring Fund may not be able to readily dispose of such investments at prices that approximate those at which the Acquiring Fund could sell such investments if they were more widely-traded and, as a result of such illiquidity, the Acquiring Fund may have to sell other investments or engage in borrowing transactions if necessary to raise cash to meet its obligations. Limited liquidity can also affect the market price of investments, thereby adversely affecting the Acquiring Fund’s NAV and ability to make dividend distributions. The financial markets in general, and certain segments of the mortgage related securities markets in particular, have in recent years experienced periods of extreme secondary market supply and demand imbalance, resulting in a loss of liquidity during which market prices were suddenly and substantially below traditional measures of intrinsic value. During such periods, some investments could be sold only at arbitrary prices and with substantial losses. Periods of such market dislocation may occur again at any time. Privately issued debt securities are often of below investment grade quality, frequently are unrated and present many of the same risks as investing in below investment grade public debt securities.

Restricted securities are securities that may not be sold to the public without an effective registration statement under the Securities Act, or that may be sold only in a privately negotiated transaction or pursuant to an exemption from registration. For example, Rule 144A under the Securities Act provides an exemption from the registration requirements of the Securities Act for the resale of certain restricted securities to qualified institutional buyers, such as the Acquiring Fund. However, an insufficient number of qualified institutional buyers interested in purchasing the Rule 144A-eligible securities that the Acquiring Fund holds could affect adversely the marketability of certain Rule 144A securities, and the Acquiring Fund might be unable to dispose of such securities promptly or at reasonable prices. When registration is required to sell a security, the Acquiring Fund may be obligated to pay all or part of the registration expenses and considerable time may pass before the Acquiring Fund is permitted to sell a security under an effective registration statement. If adverse market conditions develop during this period, the Acquiring Fund might obtain a less favorable price than the price that prevailed when the Acquiring Fund decided to sell. The Acquiring Fund may be unable to sell restricted and other illiquid investments at opportune times or prices.

Investment Companies Risk. Subject to the limitations set forth in the 1940 Act and the Acquiring Fund’s governing documents or as otherwise permitted by the SEC, the Acquiring Fund may acquire shares in other affiliated and unaffiliated investment companies, including exchange-traded funds (“ETFs”) and business development companies (“BDCs”). The market value of the shares of other investment companies may differ from their NAV. As an investor in investment companies, including ETFs or BDCs, the Acquiring Fund would bear its ratable share of that entity’s expenses, including its investment advisory and administration fees, while continuing to pay its own advisory and administration fees and other expenses. As a result, shareholders will be absorbing duplicate levels of fees with respect to investments in other investment companies, including ETFs or BDCs.

59

The securities of other investment companies, including ETFs or BDCs, in which the Acquiring Fund may invest may be leveraged. As a result, the Acquiring Fund may be indirectly exposed to leverage through an investment in such securities. An investment in securities of other investment companies, including ETFs or BDCs, that use leverage may expose the Acquiring Fund to higher volatility in the market value of such securities and the possibility that the Acquiring Fund’s long-term returns on such securities (and, indirectly, the long-term returns of the Acquiring Fund’s common shares) will be diminished.

ETFs are generally not actively managed and may be affected by a general decline in market segments relating to its index. An ETF typically invests in securities included in, or representative of, its index regardless of their investment merits and does not attempt to take defensive positions in declining markets.

Strategic Transactions and Derivatives Risk. The Acquiring Fund may engage in various derivative transactions or portfolio strategies (“Strategic Transactions”) for duration management and other risk management purposes, including to attempt to protect against possible changes in the market value of the Acquiring Fund’s portfolio resulting from trends in the securities markets and changes in interest rates or to protect the Acquiring Fund’s unrealized gains in the value of its portfolio securities, to facilitate the sale of portfolio securities for investment purposes or to establish a position in the securities markets as a temporary substitute for purchasing particular securities or to enhance income or gain. Derivatives are financial contracts or instruments whose value depends on, or is derived from, the value of an underlying asset, reference rate or index (or relationship between two indices). The Acquiring Fund also may use derivatives to add leverage to the portfolio and/or to hedge against increases in the Acquiring Fund’s costs associated with any leverage strategy that it may employ. The use of Strategic Transactions to enhance current income may be particularly speculative.

Strategic Transactions involve risks. The risks associated with Strategic Transactions include (i) the imperfect correlation between the value of such instruments and the underlying assets, (ii) the possible default of the counterparty to the transaction, (iii) illiquidity of the derivative instruments, and (iv) high volatility losses caused by unanticipated market movements, which are potentially unlimited. Although both over-the-counter (“OTC”) and exchange-traded derivatives markets may experience a lack of liquidity, OTC non-standardized derivative transactions are generally less liquid than exchange-traded instruments. The illiquidity of the derivatives markets may be due to various factors, including congestion, disorderly markets, limitations on deliverable supplies, the participation of speculators, government regulation and intervention, and technical and operational or system failures. In addition, daily limits on price fluctuations and speculative position limits on exchanges on which the Acquiring Fund may conduct its transactions in derivative instruments may prevent prompt liquidation of positions, subjecting the Acquiring Fund to the potential of greater losses. Furthermore, the Acquiring Fund’s ability to successfully use Strategic Transactions depends on the Investment Advisor’s ability to predict pertinent securities prices, interest rates, currency exchange rates and other economic factors, which cannot be assured. The use of Strategic Transactions may result in losses greater than if they had not been used, may require the Acquiring Fund to sell or purchase portfolio securities at inopportune times or for prices other than current market values, may limit the amount of appreciation the Acquiring Fund can realize on an investment or may cause the Acquiring Fund to hold a security that it might otherwise sell. Additionally, segregated or earmarked liquid assets, amounts paid by the Acquiring Fund as premiums and cash or other assets held in margin accounts with respect to Strategic Transactions are not otherwise available to the Acquiring Fund for investment purposes.

Exchange-traded derivatives and OTC derivative transactions submitted for clearing through a central counterparty are also subject to minimum initial and variation margin requirements set by the relevant clearinghouse, as well as possible SEC- or Commodity Futures Trading Commission (“CFTC”) mandated margin requirements. The CFTC and federal banking regulators also have imposed margin requirements on non-cleared OTC derivatives, and the SEC has proposed (but not yet finalized) such non-cleared margin requirements. As applicable, margin requirements will increase the overall costs for the Acquiring Fund.

Many OTC derivatives are valued on the basis of dealers’ pricing of these instruments. However, the price at which dealers value a particular derivative and the price that the same dealers would actually be willing to pay

60

for such derivative should the Acquiring Fund wish or be forced to sell such position may be materially different. Such differences can result in an overstatement of the Acquiring Fund’s NAV and may materially adversely affect the Acquiring Fund in situations in which the Acquiring Fund is required to sell derivative instruments.

While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. Hedges are sometimes subject to imperfect matching between the derivative and the underlying security, and there can be no assurances that the Acquiring Fund’s hedging transactions will be effective.

Derivatives may give rise to a form of leverage and may expose the Acquiring Fund to greater risk and increase its costs. Recent legislation calls for new regulation of the derivatives markets. The extent and impact of the regulation is not yet known and may not be known for some time. New regulation may make derivatives more costly, may limit the availability of derivatives, or may otherwise adversely affect the value or performance of derivatives.

In November 2019, the SEC proposed new regulations governing the use of derivatives by registered investment companies. If adopted as proposed, new Rule 18f-4 would impose limits on the amount of derivatives a fund could enter into, eliminate the asset segregation framework currently used by funds to comply with Section 18 of the 1940 Act, treat derivatives as senior securities so that a failure to comply with the proposed limits would result in a statutory violation and require funds whose use of derivatives is more than a limited specified exposure amount to establish and maintain a comprehensive derivatives risk management program and appoint a derivatives risk manager.

The Acquiring Fund’s use of derivative instruments involves risks different from, and possibly greater than, the risks associated with investing directly in securities and other traditional investments. Derivatives are subject to a number of risks such as credit risk, currency risk, leverage risk, liquidity risk, correlation risk, index risk and volatility as described below:

61

When a derivative is used as a hedge against a position that the Acquiring Fund holds, any loss generated by the derivative generally should be substantially offset by gains on the hedged investment, and vice versa. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. Hedges are sometimes subject to imperfect matching between the derivative and the underlying security, and there can be no assurances that the Acquiring Fund’s hedging transactions will be effective. The Acquiring Fund could also suffer losses related to its derivative positions as a result of unanticipated market movements, which losses are potentially unlimited. The Investment Advisor may not be able to predict correctly the direction of securities prices, interest rates and other economic factors, which could cause the Acquiring Fund’s derivatives positions to lose value. In addition, some derivatives are more sensitive to interest rate changes and market price fluctuations than other securities. The possible lack of a liquid secondary market for derivatives and the resulting inability of the Acquiring Fund to sell or otherwise close a derivatives position could expose the Acquiring Fund to losses and could make derivatives more difficult for the Acquiring Fund to value accurately.

When engaging in a hedging transaction, the Acquiring Fund may determine not to seek to establish a perfect correlation between the hedging instruments utilized and the portfolio holdings being hedged. Such an imperfect correlation may prevent the Acquiring Fund from achieving the intended hedge or expose the Acquiring Fund to a risk of loss. The Acquiring Fund may also determine not to hedge against a particular risk

62

because it does not regard the probability of the risk occurring to be sufficiently high as to justify the cost of the hedge or because it does not foresee the occurrence of the risk. It may not be possible for the Acquiring Fund to hedge against a change or event at attractive prices or at a price sufficient to protect the assets of the Acquiring Fund from the decline in value of the portfolio positions anticipated as a result of such change. The Acquiring Fund may also be restricted in its ability to effectively manage the portion of its assets that are segregated or earmarked to cover its obligations. In addition, it may not be possible to hedge at all against certain risks.

If the Acquiring Fund invests in a derivative instrument it could lose more than the principal amount invested. Moreover, derivatives raise certain tax, legal, regulatory and accounting issues that may not be presented by investments in securities, and there is some risk that certain issues could be resolved in a manner that could adversely impact the performance of the Acquiring Fund.

The Acquiring Fund is not required to use derivatives or other portfolio strategies to seek to increase return or to seek to hedge its portfolio and may choose not to do so. Also, suitable derivative transactions may not be available in all circumstances and there can be no assurances that the Acquiring Fund will engage in these transactions to reduce exposure to other risks when that would be beneficial. Although the Investment Advisor seeks to use derivatives to further the Acquiring Fund’s investment objective, there is no assurance that the use of derivatives will achieve this result.

Options Risk. There are several risks associated with transactions in options on securities and indexes. For example, there are significant differences between the securities and options markets that could result in an imperfect correlation between these markets, causing a given transaction not to achieve its objective. In addition, a liquid secondary market for particular options, whether traded OTC or on a recognized securities exchange (e.g., NYSE), separate trading boards of a securities exchange or through a market system that provides contemporaneous transaction pricing information (an “exchange”) may be absent for reasons which include the following: there may be insufficient trading interest in certain options; restrictions may be imposed by an exchange on opening transactions or closing transactions or both; trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of options or underlying securities; unusual or unforeseen circumstances may interrupt normal operations on an exchange; the facilities of an exchange or the Office of the Comptroller of the Currency (“OCC”) may not at all times be adequate to handle current trading volume; or one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of options (or a particular class or series of options), in which event the secondary market on that exchange (or in that class or series of options) would cease to exist, although outstanding options that had been issued by the OCC as a result of trades on that exchange would continue to be exercisable in accordance with their terms.

Futures Transactions and Options Risk. The primary risks associated with the use of futures contracts and options are (a) the imperfect correlation between the change in market value of the instruments held by the Acquiring Fund and the price of the futures contract or option; (b) possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the Investment Advisor’s inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; and (e) the possibility that the counterparty will default in the performance of its obligations.

Investment in futures contracts involves the risk of imperfect correlation between movements in the price of the futures contract and the price of the security being hedged. The hedge will not be fully effective when there is imperfect correlation between the movements in the prices of two financial instruments. For example, if the price of the futures contract moves more or less than the price of the hedged security, the Acquiring Fund will experience either a loss or gain on the futures contract which is not completely offset by movements in the price of the hedged securities. To compensate for imperfect correlations, the Acquiring Fund may purchase or sell futures contracts in a greater dollar amount than the hedged securities if the volatility of the hedged securities is historically greater than the volatility of the futures contracts. Conversely, the Acquiring Fund may purchase or

63

sell fewer futures contracts if the volatility of the price of the hedged securities is historically lower than that of the futures contracts.

The particular securities comprising the index underlying a securities index financial futures contract may vary from the securities held by the Acquiring Fund. As a result, the Acquiring Fund’s ability to hedge effectively all or a portion of the value of its securities through the use of such financial futures contracts will depend in part on the degree to which price movements in the index underlying the financial futures contract correlate with the price movements of the securities held by the Acquiring Fund. The correlation may be affected by disparities in the average maturity, ratings, geographical mix or structure of the Acquiring Fund’s investments as compared to those comprising the securities index and general economic or political factors. In addition, the correlation between movements in the value of the securities index may be subject to change over time as additions to and deletions from the securities index alter its structure. The correlation between futures contracts on U.S. Government securities and the securities held by the Acquiring Fund may be adversely affected by similar factors and the risk of imperfect correlation between movements in the prices of such futures contracts and the prices of securities held by the Acquiring Fund may be greater. The trading of futures contracts also is subject to certain market risks, such as inadequate trading activity, which could at times make it difficult or impossible to liquidate existing positions.

The Acquiring Fund may liquidate futures contracts it enters into through offsetting transactions on the applicable contract market. There can be no assurances, however, that a liquid secondary market will exist for any particular futures contract at any specific time. Thus, it may not be possible to close out a futures position. In the event of adverse price movements, the Acquiring Fund would continue to be required to make daily cash payments of variation margin. In such situations, if the Acquiring Fund has insufficient cash, it may be required to sell portfolio securities to meet daily variation margin requirements at a time when it may be disadvantageous to do so. The inability to close out futures positions also could have an adverse impact on the Acquiring Fund’s ability to hedge effectively its investments in securities. The liquidity of a secondary market in a futures contract may be adversely affected by “daily price fluctuation limits” established by commodity exchanges which limit the amount of fluctuation in a futures contract price during a single trading day. Once the daily limit has been reached in the contract, no trades may be entered into at a price beyond the limit, thus preventing the liquidation of open futures positions. Prices have in the past moved beyond the daily limit on a number of consecutive trading days. The Acquiring Fund will enter into a futures position only if, in the judgement of the Investment Advisor, there appears to be an actively traded secondary market for such futures contracts.

The successful use of transactions in futures and related options also depends on the ability of the Investment Advisor to forecast correctly the direction and extent of interest rate movements within a given time frame. To the extent interest rates remain stable during the period in which a futures contract or option is held by the Acquiring Fund or such rates move in a direction opposite to that anticipated, the Acquiring Fund may realize a loss on the Strategic Transaction which is not fully or partially offset by an increase in the value of portfolio securities. As a result, the Acquiring Fund’s total return for such period may be less than if it had not engaged in the Strategic Transaction.

Because of low initial margin deposits made upon the opening of a futures position, futures transactions involve substantial leverage. As a result, relatively small movements in the price of the futures contracts can result in substantial unrealized gains or losses. There is also the risk of loss by the Acquiring Fund of margin deposits in the event of bankruptcy of a broker with which the Acquiring Fund has an open position in a financial futures contract. Because the Acquiring Fund will engage in the purchase and sale of futures contracts for hedging purposes or to seek to enhance the Acquiring Fund’s return, any losses incurred in connection therewith may, if the strategy is successful, be offset in whole or in part by increases in the value of securities held by the Acquiring Fund or decreases in the price of securities the Acquiring Fund intends to acquire.

The amount of risk the Acquiring Fund assumes when it purchases an option on a futures contract is the premium paid for the option plus related transaction costs. In addition to the correlation risks discussed above,

64

the purchase of an option on a futures contract also entails the risk that changes in the value of the underlying futures contract will not be fully reflected in the value of the option purchased.

Counterparty Risk. The Acquiring Fund will be subject to credit risk with respect to the counterparties to the derivative contracts purchased by the Acquiring Fund. Because derivative transactions in which the Acquiring Fund may engage may involve instruments that are not traded on an exchange or cleared through a central counterparty but are instead traded between counterparties based on contractual relationships, the Acquiring Fund is subject to the risk that a counterparty will not perform its obligations under the related contracts. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Acquiring Fund may experience significant delays in obtaining any recovery in bankruptcy or other reorganization proceedings. The Acquiring Fund may obtain only a limited recovery, or may obtain no recovery, in such circumstances. Although the Acquiring Fund intends to enter into transactions only with counterparties that the Investment Advisor believes to be creditworthy, there can be no assurances that, as a result, a counterparty will not default and that the Acquiring Fund will not sustain a loss on a transaction. In the event of the counterparty’s bankruptcy or insolvency, the Acquiring Fund’s collateral may be subject to the conflicting claims of the counterparty’s creditors, and the Acquiring Fund may be exposed to the risk of a court treating the Acquiring Fund as a general unsecured creditor of the counterparty, rather than as the owner of the collateral.

The counterparty risk for cleared derivatives is generally lower than for uncleared OTC derivative transactions since generally a clearing organization becomes substituted for each counterparty to a cleared derivative contract and, in effect, guarantees the parties’ performance under the contract as each party to a trade looks only to the clearing organization for performance of financial obligations under the derivative contract. However, there can be no assurances that a clearing organization, or its members, will satisfy its obligations to the Acquiring Fund, or that the Acquiring Fund would be able to recover the full amount of assets deposited on its behalf with the clearing organization in the event of the default by the clearing organization or the Acquiring Fund’s clearing broker. In addition, cleared derivative transactions benefit from daily marking-to-market and settlement, and segregation and minimum capital requirements applicable to intermediaries. Uncleared OTC derivative transactions generally do not benefit from such protections. This exposes the Acquiring Fund to the risk that a counterparty will not settle a transaction in accordance with its terms and conditions because of a dispute over the terms of the contract (whether or not bona fide) or because of a credit or liquidity problem, thus causing the Acquiring Fund to suffer a loss. Such “counterparty risk” is accentuated for contracts with longer maturities where events may intervene to prevent settlement, or where the Acquiring Fund has concentrated its transactions with a single or small group of counterparties.

In addition, the Acquiring Fund is subject to the risk that issuers of the instruments in which it invests and trades may default on their obligations under those instruments, and that certain events may occur that have an immediate and significant adverse effect on the value of those instruments. There can be no assurances that an issuer of an instrument in which the Acquiring Fund invests will not default, or that an event that has an immediate and significant adverse effect on the value of an instrument will not occur, and that the Acquiring Fund will not sustain a loss on a transaction as a result.

Swaps Risk. Swaps are a type of derivative. Swap agreements involve the risk that the party with which the Acquiring Fund has entered into the swap will default on its obligation to pay the Acquiring Fund and the risk that the Acquiring Fund will not be able to meet its obligations to pay the other party to the agreement. In order to seek to hedge the value of the Acquiring Fund’s portfolio, to hedge against increases in the Acquiring Fund’s cost associated with interest payments on any outstanding borrowings or to seek to increase the Acquiring Fund’s return, the Acquiring Fund may enter into swaps, including interest rate swap, total return swap and/or credit default swap transactions. In interest rate swap transactions, there is a risk that yields will move in the direction opposite of the direction anticipated by the Acquiring Fund, which would cause the Acquiring Fund to make payments to its counterparty in the transaction that could adversely affect Acquiring Fund performance. In addition to the risks applicable to swaps generally (including counterparty risk, high volatility, liquidity risk and credit risk), credit default swap transactions involve special risks because they are difficult to value, are highly

65

susceptible to liquidity and credit risk, and generally pay a return to the party that has paid the premium only in the event of an actual default by the issuer of the underlying obligation (as opposed to a credit downgrade or other indication of financial difficulty).

Historically, swap transactions have been individually negotiated non-standardized transactions entered into in OTC markets and have not been subject to the same type of government regulation as exchange-traded instruments. However, since the global financial crisis, the OTC derivatives markets have recently become subject to comprehensive statutes and regulations. In particular, in the United States, the Dodd-Frank Act requires that certain derivatives with U.S. persons must be executed on a regulated market and a substantial portion of OTC derivatives must be submitted for clearing to regulated clearinghouses. As a result, swap transactions entered into by the Acquiring Fund may become subject to various requirements applicable to swaps under the Dodd-Frank Act, including clearing, exchange-execution, reporting and recordkeeping requirements, which may make it more difficult and costly for the Acquiring Fund to enter into swap transactions and may also render certain strategies in which the Acquiring Fund might otherwise engage impossible or so costly that they will no longer be economical to implement. Furthermore, the number of counterparties that may be willing to enter into swap transactions with the Acquiring Fund may also be limited if the swap transactions with the Acquiring Fund are subject to the swap regulation under the Dodd-Frank Act.

Credit default and total return swap agreements may effectively add leverage to the Acquiring Fund’s portfolio because, in addition to its Managed Assets, the Acquiring Fund would be subject to investment exposure on the notional amount of the swap. Total return swap agreements are subject to the risk that a counterparty will default on its payment obligations to the Acquiring Fund thereunder. The Acquiring Fund is not required to enter into swap transactions for hedging purposes or to enhance income or gain and may choose not to do so. In addition, the swaps market is subject to a changing regulatory environment. It is possible that regulatory or other developments in the swaps market could adversely affect the Acquiring Fund’s ability to successfully use swaps.

Over-the-Counter Trading Risk. The derivative instruments that may be purchased or sold by the Acquiring Fund may include instruments not traded on an exchange. The risk of nonperformance by the counterparty to an instrument may be greater than, and the ease with which the Acquiring Fund can dispose of or enter into closing transactions with respect to an instrument may be less than, the risk associated with an exchange traded instrument. In addition, significant disparities may exist between “bid” and “asked” prices for derivative instruments that are not traded on an exchange. Derivative instruments not traded on exchanges also are not subject to the same type of government regulation as exchange traded instruments, and many of the protections afforded to participants in a regulated environment may not be available in connection with the transactions. Because derivatives traded in OTC markets generally are not guaranteed by an exchange or clearing corporation, to the extent that the Acquiring Fund has unrealized gains in such instruments or has deposited collateral with its counterparties, the Acquiring Fund is at risk that its counterparties will become bankrupt or otherwise fail to honor its obligations.

Certain derivatives traded in OTC markets, including indexed securities, swaps and OTC options, involve substantial liquidity risk. The absence of liquidity may make it difficult or impossible for the Acquiring Fund to sell such instruments promptly at an acceptable price. The absence of liquidity may also make it more difficult for the Acquiring Fund to ascertain a market value for such instruments. The Acquiring Fund will, therefore, acquire illiquid OTC instruments (i) if the agreement pursuant to which the instrument is purchased contains a formula price at which the instrument may be terminated or sold, or (ii) for which the Investment Advisor anticipates the Acquiring Fund can receive on each business day at least two independent bids or offers, unless a quotation from only one dealer is available, in which case that dealer’s quotation may be used. Because derivatives traded in OTC markets are not guaranteed by an exchange or clearing corporation and generally do not require payment of margin, to the extent that the Acquiring Fund has unrealized gains in such instruments or has deposited collateral with its counterparties the Acquiring Fund is at risk that its counterparties will become bankrupt or otherwise fail to honor its obligations. The Acquiring Fund will attempt to minimize these risks by

66

engaging in transactions in derivatives traded in OTC markets only with financial institutions that have substantial capital or that have provided the Acquiring Fund with a third-party guaranty or other credit enhancement.

Dodd-Frank Act Risk. Title VII of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) (the “Derivatives Title”) imposed a substantially new regulatory structure on derivatives markets, with particular emphasis on swaps (which were subject to oversight by the CFTC) and security-based swaps (which were subject to oversight by the SEC). The regulatory framework covers a broad range of swap market participants, including banks, non-banks, credit unions, insurance companies, broker-dealers and investment advisers. Prudential regulators were granted authority to regulate margining of swaps and security-based swaps of banks and bank-related entities.

Although the CFTC and the prudential regulators have adopted and have begun implementing required regulations, the SEC rules were not finalized until December 2019 and firms have until October 2021 to come into compliance.

Current regulations for swaps require the mandatory central clearing and mandatory exchange trading of particular types of interest rate swaps and index credit default swaps (together, “Covered Swaps”). The Fund is required to clear its Covered Swaps through a clearing broker, which requires, among other things, posting initial margin and variation margin to the Fund’s clearing broker in order to enter into and maintain positions in Covered Swaps.

Covered Swaps generally are required to be executed through a swap execution facility (“SEF”), which can involve additional transaction fees.

Additionally, under the Dodd-Frank Act, swaps (and both swaps and security-based swaps entered into with banks) are subject to margin requirements and swap dealers are required to collect margin from the Fund and post variation margin to the Fund with respect to such derivatives. Specifically, regulations are now in effect that require swap dealers to post and collect variation margin (comprised of specified liquid instruments and subject to a required haircut) in connection with trading of OTC swaps with the Fund. Shares of investment companies (other than certain money market funds) may not be posted as collateral under these regulations. Requirements for posting of initial margin in connection with OTC swaps (as well as security-based swaps in addition to OTC swaps where the dealer is a bank or subsidiary of a bank holding company) will be phased-in through September 2021. The CFTC has not yet adopted capital requirements for swap dealers. As uncleared capital requirements for swap dealers and uncleared capital and margin requirements for security-based swaps are phased in and implemented, such requirements may make certain types of trades and/or trading strategies more costly. There may be market dislocations due to uncertainty during the implementation period of any new regulation and the Investment Advisor cannot know how the derivatives market will adjust to the CFTC’s new capital regulations and to the new SEC regulations governing security-based swaps.

In addition, regulations adopted by global prudential regulators that are now in effect require certain bank- regulated counterparties and certain of their affiliates to include in “qualified financial contracts,” including many derivatives contracts as well as repurchase agreements and securities lending agreements, terms that delay or restrict the rights of counterparties to terminate such contracts, foreclose upon collateral, exercise other default rights or restrict transfers of affiliate credit enhancements (such as guarantees) in the event that the bank-regulated counterparty and/or its affiliates are subject to certain types of resolution or insolvency proceedings.

Legal and Regulatory Risk. At any time after the date hereof, legislation or additional regulations may be enacted that could negatively affect the assets of the Acquiring Fund. Changing approaches to regulation may have a negative impact on the securities in which the Acquiring Fund invests. Legislation or regulation may also change the way in which the Acquiring Fund itself is regulated. There can be no assurance that future legislation, regulation or deregulation will not have a material adverse effect on the Acquiring Fund or will not impair the

67

ability of the Acquiring Fund to achieve its investment objective. In addition, as new rules and regulations resulting from the passage of the Dodd-Frank Act are implemented and new international capital and liquidity requirements are introduced under the Basel III Accords, the market may not react the way the Investment Advisor expects. Whether the Acquiring Fund achieves its investment objective may depend on, among other things, whether the Investment Advisor correctly forecasts market reactions to this and other legislation. In the event the Investment Advisor incorrectly forecasts market reaction, the Acquiring Fund may not achieve its investment objective.

Regulation as a “Commodity Pool.” The CFTC subjects advisers to registered investment companies to regulation by the CFTC if a fund that is advised by the investment adviser either (i) invests, directly or indirectly, more than a prescribed level of its liquidation value in CFTC-regulated futures, options and swaps (“CFTC Derivatives”), or (ii) markets itself as providing investment exposure to such instruments. To the extent the Acquiring Fund uses CFTC Derivatives, it intends to do so below such prescribed levels and will not market itself as a “commodity pool” or a vehicle for trading such instruments. Accordingly, the Investment Advisor has claimed an exclusion from the definition of the term “commodity pool operator” under the Commodity Exchange Act (“CEA”) pursuant to Rule 4.5 under the CEA. The Investment Advisor is not, therefore, subject to registration or regulation as a “commodity pool operator” under the CEA in respect of the Acquiring Fund.

Failure of Futures Commission Merchants and Clearing Organizations. The Acquiring Fund is required to deposit funds to margin open positions in cleared derivative instruments (both futures and swaps) with a clearing broker registered as a “futures commission merchant” (“FCM”). The CEA requires an FCM to segregate all funds received from customers with respect to any orders for the purchase or sale of U.S. domestic futures contracts and cleared swaps from the FCM’s proprietary assets. Similarly, the CEA requires each FCM to hold in a separate secure account all funds received from customers with respect to any orders for the purchase or sale of foreign futures contracts and segregate any such funds from the funds received with respect to domestic futures contracts. However, all funds and other property received by an FCM from its customers are held by an FCM on a commingled basis in an omnibus account and amounts in excess of assets posted to the clearing organization may be invested by an FCM in certain instruments permitted under the applicable regulation. There is a risk that assets deposited by the Acquiring Fund with any FCM as margin for futures contracts or commodity options may, in certain circumstances, be used to satisfy losses of other clients of the Acquiring Fund’s FCM. In addition, the assets of the Acquiring Fund posted as margin against both swaps and futures contracts may not be fully protected in the event of the FCM’s bankruptcy.

Legal, Tax and Regulatory Risks. Legal, tax and regulatory changes could occur that may have material adverse effects on the Acquiring Fund. For example, the regulatory and tax environment for derivative instruments in which the Acquiring Fund may participate is evolving, and such changes in the regulation or taxation of derivative instruments may have material adverse effects on the value of derivative instruments held by the Acquiring Fund and the ability of the Acquiring Fund to pursue its investment strategies.

To qualify for the favorable U.S. federal income tax treatment generally accorded to RICs, the Acquiring Fund must, among other things, derive in each taxable year at least 90% of its gross income from certain prescribed sources and distribute for each taxable year at least 90% of its “investment company taxable income” (generally, ordinary income plus the excess, if any, of net short-term capital gain over net long-term capital loss) and at least 90% of its net tax-exempt interest income, if any. If for any taxable year the Acquiring Fund does not qualify as a RIC, all of its taxable income for that year (including its net capital gain) would be subject to tax at regular corporate rates without any deduction for distributions to shareholders, and such distributions would be taxable as ordinary dividends to the extent of the Acquiring Fund’s current and accumulated earnings and profits.

The current presidential administration has called for, and in certain instances has begun to implement, significant changes to U.S. fiscal, tax, trade, healthcare, immigration, foreign, and government regulatory policy. In this regard, there is significant uncertainty with respect to legislation, regulation and government policy at the federal level, as well as the state and local levels. Recent events have created a climate of heightened uncertainty

68

and introduced new and difficult-to-quantify macroeconomic and political risks with potentially far-reaching implications. There has been a corresponding meaningful increase in the uncertainty surrounding interest rates, inflation, foreign exchange rates, trade volumes and fiscal and monetary policy. To the extent the U.S. Congress or the current presidential administration implements changes to U.S. policy, those changes may impact, among other things, the U.S. and global economy, international trade and relations, unemployment, immigration, corporate taxes, healthcare, the U.S. regulatory environment, inflation and other areas. Some particular areas identified as subject to potential change, amendment or repeal include the Dodd-Frank Act, including the Volcker Rule and various swaps and derivatives regulations, credit risk retention requirements and the authorities of the Federal Reserve, the Financial Stability Oversight Council and the SEC. Although the Acquiring Fund cannot predict the impact, if any, of these changes to the Acquiring Fund’s business, they could adversely affect the Acquiring Fund’s business, financial condition, operating results and cash flows. Until the Acquiring Fund knows what policy changes are made and how those changes impact the Acquiring Fund’s business and the business of the Acquiring Fund’s competitors over the long-term, the Acquiring Fund will not know if, overall, the Acquiring Fund will benefit from them or be negatively affected by them.

The risks and uncertainties associated with these policy proposals are heightened by the 2018 U.S. federal election, which has resulted in different political parties controlling the U.S. House of Representatives, on the one hand, and the U.S. Senate and the Executive Branch, on the other hand. Additional risks arising from the differences in expressed policy preferences among the various constituencies in these branches of the U.S. government has led in the past, and may lead in the future, to short-term or prolonged policy impasses, which could, and has, resulted in shutdowns of the U.S. federal government. U.S. federal government shutdowns, especially prolonged shutdowns, could have a significant adverse impact on the economy in general and could impair the ability of issuers to raise capital in the securities markets. Any of these effects could have an adverse impact on companies in the Acquiring Fund’s portfolio and consequently on the value of their securities and the Acquiring Fund’s NAV.

The rules dealing with U.S. federal income taxation are constantly under review by persons involved in the legislative process and by the IRS and the U.S. Treasury Department. The Acquiring Fund cannot predict how any changes in the tax laws might affect its investors or the Acquiring Fund itself. New legislation, U.S. Treasury regulations, administrative interpretations or court decisions, with or without retroactive application, could significantly and negatively affect the Acquiring Fund’s ability to qualify as a RIC or the U.S. federal income tax consequences to its investors and itself of such qualification, or could have other adverse consequences. You are urged to consult with your tax advisor with respect to the status of legislative, regulatory or administrative developments and proposals and their potential effect on an investment in the Acquiring Fund’s shares.

1940 Act Regulation. The Acquiring Fund is a registered closed-end management investment company and as such is subject to regulations under the 1940 Act. Generally speaking, any contract or provision thereof that is made, or where performance involves a violation of the 1940 Act or any rule or regulation thereunder is unenforceable by either party unless a court finds otherwise.

Legislation Risk. At any time after the date of this Proxy Statement, legislation may be enacted that could negatively affect the assets of the Acquiring Fund. Legislation or regulation may change the way in which the Acquiring Fund itself is regulated. The Investment Advisor cannot predict the effects of any new governmental regulation that may be implemented and there can be no assurance that any new governmental regulation will not adversely affect the Acquiring Fund’s ability to achieve its investment objective.

LIBOR Risk. The Acquiring Fund may be exposed to financial instruments that are tied to the London Interbank Offered Rate (“LIBOR”) to determine payment obligations, financing terms, hedging strategies or investment value. The Acquiring Fund’s investments may pay interest at floating rates based on LIBOR or may be subject to interest caps or floors based on LIBOR. The Acquiring Fund may also obtain financing at floating rates based on LIBOR. Derivative instruments utilized by the Acquiring Fund may also reference LIBOR.

69

In 2017, the head of the United Kingdom’s Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021, and it is expected that LIBOR will cease to be published after that time. The Acquiring Fund may have investments linked to other interbank offered rates, such as the Euro Overnight Index Average (“EONIA”), which may also cease to be published. Various financial industry groups have begun planning for the transition away from LIBOR, but there are challenges to converting certain securities and transactions to a new reference rate (e.g., the Secured Overnight Financing Rate (“SOFR”), which is intended to replace the U.S. dollar LIBOR).

Neither the effect of the LIBOR transition process nor its ultimate success can yet be known. The transition process might lead to increased volatility and illiquidity in markets for, and reduce the effectiveness of new hedges placed against, instruments whose terms currently include LIBOR. While some existing LIBOR-based instruments may contemplate a scenario where LIBOR is no longer available by providing for an alternative rate-setting methodology, there may be significant uncertainty regarding the effectiveness of any such alternative methodologies to replicate LIBOR. Not all existing LIBOR-based instruments may have alternative rate-setting provisions and there remains uncertainty regarding the willingness and ability of issuers to add alternative rate-setting provisions in certain existing instruments. In addition, a liquid market for newly issued instruments that use a reference rate other than LIBOR still may be developing. There may also be challenges for the Acquiring Fund to enter into hedging transactions against such newly issued instruments until a market for such hedging transactions develops. All of the aforementioned may adversely affect the Acquiring Fund’s performance or NAV.

Risks Associated with Recent Market Events. Stresses associated with the 2008 financial crisis in the United States and global economies peaked approximately a decade ago, but periods of unusually high volatility in the financial markets and restrictive credit conditions, sometimes limited to a particular sector or a geography, continue to recur. Some countries, including the United States, have adopted and/or are considering the adoption of more protectionist trade policies, a move away from the tighter financial industry regulations that followed the financial crisis, and/or substantially reducing corporate taxes. The exact shape of these policies is still being considered, but the equity and debt markets may react strongly to expectations of change, which could increase volatility, especially if the market’s expectations are not borne out. A rise in protectionist trade policies, and the possibility of changes to some international trade agreements, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, geopolitical and other risks, including environmental and public health, may add to instability in world economies and markets generally. Economies and financial markets throughout the world are becoming increasingly interconnected. As a result, whether or not the Fund invests in securities of issuers located in or with significant exposure to countries experiencing economic, political and/or financial difficulties, the value and liquidity of the Fund’s investments may be negatively affected by such events.

An outbreak of respiratory disease caused by a novel coronavirus was first detected in China in December 2019 and has now developed into a global pandemic. The pandemic has resulted in closing borders, enhanced health screenings, healthcare service preparation and delivery, quarantines, cancellations, disruptions to supply chains and customer activity, as well as general concern and uncertainty. The impact of this pandemic, and other pandemics and epidemics that may arise in the future, could affect the economies of many nations, individual companies and the market in general in ways that cannot necessarily be foreseen at the present time. In addition, the impact of infectious diseases in developing or emerging market countries may be greater due to less established health care systems. Health crises caused by the novel coronavirus pandemic may exacerbate other pre-existing political, social and economic risks in certain countries. The impact of the pandemic may last for an extended period of time.

Market Disruption and Geopolitical Risk. The occurrence of events similar to those in recent years, such as the aftermath of the war in Iraq, instability in Afghanistan, Pakistan, Egypt, Libya, Syria, Russia, Ukraine and the Middle East, new and ongoing epidemics and pandemics of infectious diseases and other global health events, natural/environmental disasters, terrorist attacks in the United States and around the world, social and political

70

discord, debt crises (such as the Greek crisis), sovereign debt downgrades, increasingly strained relations between the United States and a number of foreign countries, including traditional allies, such as certain European countries, and historical adversaries, such as North Korea, Iran, China and Russia, and the international community generally, new and continued political unrest in various countries, such as Venezuela and Spain, the exit or potential exit of one or more countries from the European Union (the “EU”) or the European Monetary Union (the “EMU”), continued changes in the balance of political power among and within the branches of the U.S. government, among others, may result in market volatility, may have long-term effects on the U.S. and worldwide financial markets, and may cause further economic uncertainties in the United States and worldwide. The coronavirus pandemic has led to illiquidity and volatility in the municipal bond markets and may lead to downgrades in the credit quality of certain municipal issuers.

China and the United States have each recently imposed tariffs on the other country’s products. These actions may trigger a significant reduction in international trade, the oversupply of certain manufactured goods, substantial price reductions of goods and possible failure of individual companies and/or large segments of China’s export industry, which could have a negative impact on the Acquiring Fund’s performance. U.S. companies that source material and goods from China and those that make large amounts of sales in China would be particularly vulnerable to an escalation of trade tensions. Uncertainty regarding the outcome of the trade tensions and the potential for a trade war could cause the U.S. dollar to decline against safe haven currencies, such as the Japanese yen and the euro. Events such as these and their consequences are difficult to predict and it is unclear whether further tariffs may be imposed or other escalating actions may be taken in the future.

The decision made in the British referendum of June 23, 2016 to leave the EU, an event widely referred to as “Brexit,” has led to volatility in the financial markets of the United Kingdom and more broadly across Europe and may also lead to weakening in consumer, corporate and financial confidence in such markets. The formal notification to the European Council required under Article 50 of the Treaty on EU was made on March 29, 2017, following which the terms of exit were negotiated. Pursuant to an agreement between the United Kingdom and the EU, the United Kingdom left the EU on January 31, 2020, subject to a transition period ending December 31, 2020. The longer term economic, legal, political and social framework to be put in place between the United Kingdom and the EU are unclear at this stage and are likely to lead to ongoing political and economic uncertainty and periods of exacerbated volatility in both the United Kingdom and in wider European markets for some time. In particular, the decision made in Brexit may lead to a call for similar referendums in other European jurisdictions which may cause increased economic volatility in the European and global markets. This mid- to long-term uncertainty may have an adverse effect on the economy generally and on the ability of the Acquiring Fund to execute its strategies and to receive attractive returns. In particular, currency volatility may mean that the returns of the Acquiring Fund and its investments are adversely affected by market movements and may make it more difficult, or more expensive, for the Acquiring Fund to execute prudent currency hedging policies. Potential decline in the value of the British Pound and/or the Euro against other currencies, along with the potential downgrading of the United Kingdom’s sovereign credit rating, may also have an impact on the performance of portfolio companies or investments located in the United Kingdom or Europe. In light of the above, no definitive assessment can currently be made regarding the impact that Brexit will have on the Acquiring Fund, its investments or its organization more generally.

The occurrence of any of these above events could have a significant adverse impact on the value and risk profile of the Acquiring Fund’s portfolio. The Acquiring Fund does not know how long the securities markets may be affected by similar events and cannot predict the effects of similar events in the future on the U.S. economy and securities markets. There can be no assurance that similar events and other market disruptions will not have other material and adverse implications.

Regulation and Government Intervention Risk. The U.S. Government and the Federal Reserve, as well as certain foreign governments, recently have taken unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility, such as implementing stimulus packages, providing liquidity in fixed-income, commercial paper and other markets, and providing tax

71

breaks, among other actions. The reduction or withdrawal of Federal Reserve or other U.S. or non-U.S. governmental support could negatively affect financial markets generally and reduce the value and liquidity of certain securities. Additionally, with the cessation of certain market support activities, the Acquiring Fund may face a heightened level of interest rate risk as a result of a rise or increased volatility in interest rates.

Federal, state, and other governments, their regulatory agencies or self-regulatory organizations may take actions that affect the regulation of the issuers in which the Acquiring Fund invests. Legislation or regulation may also change the way in which the Acquiring Fund is regulated. Such legislation or regulation could limit or preclude the Acquiring Fund’s ability to achieve its investment objective.

In the aftermath of the global financial crisis, there appears to be a renewed popular, political and judicial focus on finance related consumer protection. Financial institution practices are also subject to greater scrutiny and criticism generally. In the case of transactions between financial institutions and the general public, there may be a greater tendency toward strict interpretation of terms and legal rights in favor of the consuming public, particularly where there is a real or perceived disparity in risk allocation and/or where consumers are perceived as not having had an opportunity to exercise informed consent to the transaction. In the event of conflicting interests between retail investors holding common shares of a closed-end investment company such as the Acquiring Fund and a large financial institution, a court may similarly seek to strictly interpret terms and legal rights in favor of retail investors. The Acquiring Fund may be affected by governmental action in ways that are not foreseeable, and there is a possibility that such actions could have a significant adverse effect on the Acquiring Fund and its ability to achieve its investment objective.

Potential Conflicts of Interest of the Investment Advisor and Others. The investment activities of BlackRock, Inc. (“BlackRock”), the ultimate parent company of the Investment Advisor, and its affiliates (including BlackRock and its subsidiaries (collectively, the “Affiliates”)), and their respective directors, officers or employees, in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Acquiring Fund and its shareholders. BlackRock and its Affiliates provide investment management services to other funds and discretionary managed accounts that may follow investment programs similar to that of the Acquiring Fund. Subject to the requirements of the 1940 Act, BlackRock and its Affiliates intend to engage in such activities and may receive compensation from third parties for their services. Neither BlackRock nor any Affiliate is under any obligation to share any investment opportunity, idea or strategy with the Acquiring Fund. As a result, BlackRock and its Affiliates may compete with the Acquiring Fund for appropriate investment opportunities. The results of the Acquiring Fund’s investment activities, therefore, may differ from those of an Affiliate and of other accounts managed by BlackRock or an Affiliate and it is possible that the Acquiring Fund could sustain losses during periods in which one or more Affiliates and other accounts achieve profits on their trading for proprietary or other accounts. BlackRock has adopted policies and procedures designed to address potential conflicts of interests.

Market and Selection Risk. Market risk is the possibility that the market values of securities owned by the Acquiring Fund will decline. There is a risk that equity and/or bond markets will go down in value, including the possibility that such markets will go down sharply and unpredictably.

Stock markets are volatile, and the price of equity securities fluctuates based on changes in a company’s financial condition and overall market and economic conditions. An adverse event, such as an unfavorable earnings report, may depress the value of a particular common stock held by the Acquiring Fund. Also, the price of common stocks is sensitive to general movements in the stock market and a drop in the stock market may depress the price of common stocks to which the Acquiring Fund has exposure. Common stock prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant stock market, or when political or economic events affecting the issuers occur.

The prices of fixed income securities tend to fall as interest rates rise, and such declines tend to be greater among fixed income securities with longer maturities. Market risk is often greater among certain types of fixed

72

income securities, such as zero-coupon bonds that do not make regular interest payments but are instead bought at a discount to their face values and paid in full upon maturity. As interest rates change, these securities often fluctuate more in price than securities that make regular interest payments and therefore subject the Acquiring Fund to greater market risk than a fund that does not own these types of securities.

When-issued and delayed delivery transactions are subject to changes in market conditions from the time of the commitment until settlement, which may adversely affect the prices or yields of the securities being purchased. The greater the Acquiring Fund’s outstanding commitments for these securities, the greater the Acquiring Fund’s exposure to market price fluctuations.

Selection risk is the risk that the securities that the Acquiring Fund’s management selects will underperform the equity and/or bond market, the market relevant indices or other funds with similar investment objectives and investment strategies.

Defensive Investing Risk. For defensive purposes, the Acquiring Fund may allocate assets into cash or short-term fixed income securities. In doing so, the Acquiring Fund may succeed in avoiding losses but may otherwise fail to achieve its investment objective. Further, the value of short-term fixed income securities may be affected by changing interest rates and by changes in credit ratings of the investments. If the Acquiring Fund holds cash uninvested it will be subject to the credit risk of the depository institution holding the cash.

Decision-Making Authority Risk. Investors have no authority to make decisions or to exercise business discretion on behalf of the Acquiring Fund, except as set forth in the Acquiring Fund’s governing documents. The authority for all such decisions is generally delegated to the Board, which in turn, has delegated the day-to-day management of the Acquiring Fund’s investment activities to the Investment Advisor, subject to oversight by the Board.

Management Risk. The Acquiring Fund is subject to management risk because it is an actively managed investment portfolio. The Investment Advisor and the individual portfolio managers will apply investment techniques and risk analyses in making investment decisions for the Acquiring Fund, but there can be no guarantee that these will produce the desired results. The Acquiring Fund may be subject to a relatively high level of management risk because the Acquiring Fund may invest in derivative instruments, which may be highly specialized instruments that require investment techniques and risk analyses different from those associated with equities and bonds.

Valuation Risk. The Acquiring Fund is subject to valuation risk, which is the risk that one or more of the securities in which the Acquiring Fund invests are valued at prices that the Acquiring Fund is unable to obtain upon sale due to factors such as incomplete data, market instability or human error. The Investment Advisor may use an independent pricing service or prices provided by dealers to value securities at their market value. Because the secondary markets for certain investments may be limited, such instruments may be difficult to value. When market quotations are not available, the Investment Advisor may price such investments pursuant to a number of methodologies, such as computer-based analytical modeling or individual security evaluations. These methodologies generate approximations of market values, and there may be significant professional disagreement about the best methodology for a particular type of financial instrument or different methodologies that might be used under different circumstances. In the absence of an actual market transaction, reliance on such methodologies is essential, but may introduce significant variances in the ultimate valuation of the Acquiring Fund’s investments. Technological issues and/or errors by pricing services or other third-party service providers may also impact the Acquiring Fund’s ability to value its investments and the calculation of the Acquiring Fund’s NAV.

When market quotations are not readily available or are deemed to be inaccurate or unreliable, the Acquiring Fund values its investments at fair value as determined in good faith pursuant to policies and procedures approved by the Board. Fair value is defined as the amount for which assets could be sold in an orderly disposition over a reasonable period of time, taking into account the nature of the asset. Fair value pricing

73

may require determinations that are inherently subjective and inexact about the value of a security or other asset. As a result, there can be no assurance that fair value priced assets will not result in future adjustments to the prices of securities or other assets, or that fair value pricing will reflect a price that the Acquiring Fund is able to obtain upon sale, and it is possible that the fair value determined for a security or other asset will be materially different from quoted or published prices, from the prices used by others for the same security or other asset and/or from the value that actually could be or is realized upon the sale of that security or other asset. For example, the Acquiring Fund’s NAV could be adversely affected if the Acquiring Fund’s determinations regarding the fair value of the Acquiring Fund’s investments were materially higher than the values that the Acquiring Fund ultimately realizes upon the disposal of such investments. Where market quotations are not readily available, valuation may require more research than for more liquid investments.    In addition, elements of judgment may play a greater role in valuation in such cases than for investments with a more active secondary market because there is less reliable objective data available. The Acquiring Fund prices its shares daily and therefore all assets, including assets valued at fair value, are valued daily.

Reliance on the Investment Advisor Risk. The Acquiring Fund is dependent upon services and resources provided by the Investment Advisor, and therefore the Investment Advisor’s parent, BlackRock. The Investment Advisor is not required to devote its full time to the business of the Acquiring Fund and there is no guarantee or requirement that any investment professional or other employee of the Investment Advisor will allocate a substantial portion of his or her time to the Acquiring Fund. The loss of one or more individuals involved with the Investment Advisor could have a material adverse effect on the performance or the continued operation of the Acquiring Fund.

Reliance on Service Providers Risk. The Acquiring Fund must rely upon the performance of service providers to perform certain functions, which may include functions that are integral to the Acquiring Fund’s operations and financial performance. Failure by any service provider to carry out its obligations to the Acquiring Fund in accordance with the terms of its appointment, to exercise due care and skill or to perform its obligations to the Acquiring Fund at all as a result of insolvency, bankruptcy or other causes could have a material adverse effect on the Acquiring Fund’s performance and returns to common shareholders. The termination of the Acquiring Fund’s relationship with any service provider, or any delay in appointing a replacement for such service provider, could materially disrupt the business of the Acquiring Fund and could have a material adverse effect on the Acquiring Fund’s performance and returns to common shareholders.

Information Technology Systems Risk. The Acquiring Fund is dependent on the Investment Advisor for certain management services as well as back-office functions. The Investment Advisor depends on information technology systems in order to assess investment opportunities, strategies and markets and to monitor and control risks for the Acquiring Fund. It is possible that a failure of some kind which causes disruptions to these information technology systems could materially limit the Investment Advisor’s ability to adequately assess and adjust investments, formulate strategies and provide adequate risk control. Any such information technology-related difficulty could harm the performance of the Acquiring Fund. Further, failure of the back-office functions of the Investment Advisor to process trades in a timely fashion could prejudice the investment performance of the Acquiring Fund.

Cyber Security Risk. With the increased use of technologies such as the Internet to conduct business, the Acquiring Fund is susceptible to operational, information security and related risks. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber-attacks include, but are not limited to, gaining unauthorized access to digital systems (e.g., through “hacking” or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cyber-attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). Cyber security failures by or breaches of the Investment Advisor and other service providers (including, but not limited to, fund accountants, custodians, transfer agents and administrators), and the issuers of securities in which the Acquiring Fund invests, have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Acquiring Fund’s ability to calculate its NAV, impediments to trading, the inability of shareholders to transact business, violations of applicable privacy and other laws, regulatory fines,

74

penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. In addition, substantial costs may be incurred in order to prevent any cyber incidents in the future. While the Acquiring Fund has established business continuity plans in the event of, and risk management systems to prevent, such cyber-attacks, there are inherent limitations in such plans and systems including the possibility that certain risks have not been identified. Furthermore, the Acquiring Fund cannot control the cyber security plans and systems put in place by service providers to the Acquiring Fund and issuers in which the Acquiring Fund invests. As a result, the Acquiring Fund or its shareholders could be negatively impacted.

Misconduct of Employees and of Service Providers Risk. Misconduct or misrepresentations by employees of the Investment Advisor or the Acquiring Fund’s service providers could cause significant losses to the Acquiring Fund. Employee misconduct may include binding the Acquiring Fund to transactions that exceed authorized limits or present unacceptable risks and unauthorized trading activities, concealing unsuccessful trading activities (which, in any case, may result in unknown and unmanaged risks or losses) or making misrepresentations regarding any of the foregoing. Losses could also result from actions by the Acquiring Fund’s service providers, including, without limitation, failing to recognize trades and misappropriating assets. In addition, employees and service providers may improperly use or disclose confidential information, which could result in litigation or serious financial harm, including limiting the Acquiring Fund’s business prospects or future marketing activities. Despite the Investment Advisor’s due diligence efforts, misconduct and intentional misrepresentations may be undetected or not fully comprehended, thereby potentially undermining the Investment Advisor’s due diligence efforts. As a result, no assurances can be given that the due diligence performed by the Investment Advisor will identify or prevent any such misconduct.

Inflation Risk. Inflation risk is the risk that the value of assets or income from investment will be worth less in the future, as inflation decreases the value of money. As inflation increases, the real value of the common shares and distributions on those shares can decline. In addition, during any periods of rising inflation, interest rates on any borrowings by the Acquiring Fund would likely increase, which would tend to further reduce returns to the common shareholders.

Deflation Risk. Deflation risk is the risk that prices throughout the economy decline over time, which may have an adverse effect on the market valuation of companies, their assets and their revenues. In addition, deflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of the Acquiring Fund’s portfolio.

Portfolio Turnover Risk. The Acquiring Fund’s annual portfolio turnover rate may vary greatly from year to year, as well as within a given year. Portfolio turnover rate is not considered a limiting factor in the execution of investment decisions for the Acquiring Fund. A higher portfolio turnover rate results in correspondingly greater brokerage commissions and other transactional expenses that are borne by the Acquiring Fund. High portfolio turnover may result in an increased realization of net short-term capital gains by the Acquiring Fund which, when distributed to common shareholders, will be taxable as ordinary income. Additionally, in a declining market, portfolio turnover may create realized capital losses.

Anti-Takeover Provisions Risk. The Agreement and Declaration of Trust and Bylaws of the Acquiring Fund include provisions that could limit the ability of other entities or persons to acquire control of the Acquiring Fund or convert the Acquiring Fund to open-end status or to change the composition of the Board.
