JRO Nuveen Floating Rate Income Opportunity Fund

PROPOSAL NO. 1—MERGER OF EACH TARGET FUND INTO THE ACQUIRING FUND

The following is a summary of certain information contained elsewhere in this Proxy Statement with respect to the proposed Mergers. More complete information is contained elsewhere in this Proxy Statement and the appendices hereto. Shareholders should read the entire Proxy Statement carefully.

Background and Reasons for the Mergers

Nuveen Fund Advisors, LLC (“Nuveen Fund Advisors” or the “Adviser”), a subsidiary of Nuveen, LLC and the Funds’ investment adviser, recommended the Merger proposals as part of an ongoing initiative to streamline Nuveen’s closed-end fund line-up and eliminate overlapping products. Each Fund’s Board considered its Fund’s Merger(s) and determined that the Merger(s) would be in the best interests of its Fund. Based on information provided by Nuveen Fund Advisors, each Target Fund’s Board believes that its Fund’s proposed Merger may benefit the common shareholders of its Fund in a number of ways, including, among other things:

With respect to holders of preferred shares of each Target Fund, the Target Fund’s Board considered that, upon the closing of the applicable Merger, holders of any preferred shares outstanding immediately prior to the closing will receive, on a one-for-one basis, newly issued preferred shares of the Acquiring Fund having substantially similar terms to those of the preferred shares of the applicable Target Fund immediately prior to the closing of the Merger.

Based on information provided by Nuveen Fund Advisors, the Acquiring Fund’s Board considered that the Acquiring Fund may also benefit from economies of scale due to a larger asset base, greater secondary market liquidity and increased portfolio and leverage management flexibility. With respect to holders of preferred shares of the Acquiring Fund, the Acquiring Fund’s Board considered that the outstanding preferred shares of the Acquiring Fund and any preferred shares of the Acquiring Fund to be issued in the Mergers would have equal priority with each other as to payment of dividends and distributions of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund.

For these reasons, each Fund’s Board has determined that its Fund’s Merger(s) are in the best interest of its Fund and has approved such Merger(s).

The closing of each Merger is subject to the satisfaction or waiver of certain closing conditions, which include customary closing conditions. In order for a Merger to occur, all requisite shareholder approvals must be obtained at the applicable Fund’s shareholder meeting, and certain other consents, confirmations and/or waivers

1

from various third parties, including the liquidity provider with respect to outstanding preferred shares of the Acquiring Fund and lenders under the Acquiring Fund’s credit facility, must also be obtained. Because the closing of each Merger is contingent upon the applicable Target Fund and the Acquiring Fund obtaining such shareholder approvals and satisfying (or obtaining the waiver of) other closing conditions, it is possible that a Merger will not occur even if shareholders of a Fund entitled to vote approve the Merger and a Fund satisfies all of its closing conditions if the other Fund does not obtain its requisite shareholder approvals or satisfy (or obtain the waiver of) its closing conditions. If a Merger is not consummated, the Board of the Target Fund involved in that Merger may take such actions as it deems in the best interests of the Fund, including conducting additional solicitations with respect to the Merger proposals or continuing to operate the Target Fund as a standalone fund. The closing of one Merger is not contingent on the closing of any other Merger.

The TFP Shares of each Fund were issued on a private placement basis to one or a small number of institutional shareholders. To the extent that one or more preferred shareholders of a Fund owns, holds or controls, individually or in the aggregate, all or a significant portion of a Fund’s outstanding preferred shares, the approval by a Fund’s preferred shareholders required for a Merger to occur may turn on the exercise of voting or consent rights by such particular shareholder(s) and its or their determination as to the favorable view of the Merger with respect to its or their interests. The Funds exercise no influence or control over the determinations of such shareholders with respect to the Mergers; there is no guarantee that such shareholders will vote to approve a Merger proposal. For a fuller discussion of the Boards’ considerations regarding the approval of the Mergers, see “C. Information About the Mergers—Reasons for the Mergers.”

Material Federal Income Tax Consequences of the Mergers

As a non-waivable condition to closing, each Fund participating in a Merger will receive an opinion of Vedder Price P.C., subject to certain representations, assumptions and conditions, substantially to the effect that the proposed Merger will qualify as a “reorganization” under Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”). Accordingly, it is expected that none of the Funds will generally recognize gain or loss for federal income tax purposes as a direct result of the Mergers. It is also expected that holders of a Target Fund’s TFP Shares who receive TFP Shares of the Acquiring Fund pursuant to a Merger will recognize no gain or loss for federal income tax purposes as a direct result of the Merger. Prior to the closing of each Merger, the Target Fund expects to declare a distribution to common shareholders of all of its undistributed net investment income and net capital gains, if any. Each Target Fund reports distributions to common and preferred shareholders as consisting of particular types of income (such as ordinary income and capital gain) based on each class’s proportionate share of the total distributions paid by the Fund with respect to that year. As a result, such distribution could affect the character of the distributions received by holders of TFP Shares with respect to the year in which such distribution is made for federal income tax purposes.

The foregoing discussion and the tax opinion discussed above to be received by the Funds regarding certain aspects of the Mergers, including that the Mergers will qualify as reorganizations under Section 368(a) of the Code, will rely on the position that the TFP Shares of the Acquiring Fund to be issued in the Mergers, if any, will constitute equity of the Acquiring Fund for federal income tax purposes. See “C. Information About the Mergers—Material Federal Income Tax Consequences of the Mergers.”

As of December 31, 2022, the Funds had outstanding the following series of preferred shares, with the Acquiring Fund’s preferred shares expected to remain outstanding following the completion of the Mergers:

Each Fund’s preferred shares are entitled to one vote per share. The TFP Shares of the Acquiring Fund to be issued in connection with the Mergers, if any, will have equal priority with the Acquiring Fund’s other outstanding preferred 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. In addition, the preferred shares of the Acquiring Fund, including any preferred shares of the Acquiring Fund to be issued in connection with the Mergers, will be senior in priority to the Acquiring Fund’s common shares as to payment of dividends and the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund. Any preferred shares of the Acquiring Fund to be issued in connection with the Mergers will have rights and preferences, including liquidation preferences, that are substantially similar to those of the corresponding Target Fund preferred shares exchanged therefor. The number of preferred shares currently outstanding may change due to market or other conditions.

Each Fund also has indebtedness outstanding under a secured revolving credit facility agreement with bank lenders. Further information on the Acquiring Fund’s credit facility is provided under “Additional Information About the Acquiring Fund— Borrowings and Priority of Payment” below. The rights of a lender under an existing credit facility or any future credit facility, and any other creditors, to receive payments of interest on and repayments of principal of any borrowings are senior to the rights of holders of preferred shares and common shares of the applicable Fund with respect to the payment of dividends and other distributions, and upon liquidation. In addition, a Fund may not be permitted to declare or make payments of dividends and other

3

distributions with respect to preferred shares and common shares (other than a dividend in common shares of the Fund), purchase common shares or preferred shares or redeem preferred shares unless, at such time, the Fund meets certain asset coverage requirements and no event of default or other circumstance exists under its credit facility or with respect to any other borrowings that would limit or otherwise preclude such payments. A Fund also may from time to time borrow on a typically transient basis in connection with its day-to-day operations, primarily in connection with the need to settle portfolio trades. Borrowings and preferred shares have seniority over the common shares. Each credit facility is secured by substantially all of the assets of the applicable Fund. The credit facility of the Acquiring Fund is referred to herein as the “Credit Facility.” Each Fund also may source leverage through other methods, including reverse repurchase agreements. See “Additional Information About the Acquiring Fund—Borrowings and Priority of Payment” below.

Investment Objectives and Policies. The Funds have similar investment objectives, policies and risks, but there are differences.

Senior Income’s investment objective is to achieve a high level of current income, consistent with preservation of capital. Floating Rate Income Opportunity’s investment objective is to achieve a high level of current income. Short Duration Credit Opportunities’ investment objective is to provide current income and the potential for capital appreciation. The Acquiring Fund’s investment objective is to achieve a high level of current income.

Each Fund is a diversified, closed-end management investment company and currently employs leverage through the issuance of preferred shares and the use of borrowing.

The following summary compares the current principal investment policies and strategies of the Acquiring Fund to the current principal investment policies and strategies of each Target Fund as of the date of this Proxy Statement.

Leverage. Each Fund currently employs leverage through the issuance of TFP Shares and secured bank borrowings (subject to investment restrictions). Each Fund also may source leverage through other methods, including reverse repurchase agreements. In addition, each Fund may use derivatives and other portfolio instruments that have the economic effect of leverage. Certain important ratios related to each Fund’s use of leverage for the last three fiscal years for which published financial statements are available are set forth below:

12

Board Members and Officers. The Acquiring Fund and the Target Funds have the same Board Members and officers. The management of each Fund, including general oversight of the duties performed by the Fund’s investment adviser under an investment management agreement between the investment adviser and such Fund (each, an “Investment Management Agreement”), is the responsibility of its Board. Each Fund currently has ten (10) Board Members, each of whom is not considered an “interested person,” as defined in the 1940 Act, of the Fund.

Pursuant to each Fund’s by-laws, the Board of the Fund is divided into three classes (Class I, Class II and Class III) with staggered multi-year terms, such that typically only the members of one of the three classes stand for election each year; provided, however, that holders of preferred shares are entitled as a class to elect two Board Members at all times. The staggered board structure could delay for up to two years the election of a majority of the Board of each Fund. To the extent that one or more preferred shareholders owns, holds or controls, individually or in aggregate, all or a significant portion of a series of a Fund’s outstanding preferred shares, a few holders could exert influence on the selection of the Board as a result of the requirement that holders of preferred shares be entitled to elect two Board Members at all times. The Acquiring Fund’s board structure will remain in place following the closing of the Mergers.

Investment Adviser. Nuveen Fund Advisors, LLC (previously defined as “Nuveen Fund Advisors” or the “Adviser”) is the investment adviser to each Fund and is responsible for overseeing each Fund’s overall investment strategy, including the use of leverage, and its implementation. Nuveen Fund Advisors also is responsible for the ongoing monitoring of any sub-adviser to the Funds, managing each Fund’s business affairs and providing certain clerical, bookkeeping and other administrative services to the Funds. Nuveen Fund Advisors is located at 333 West Wacker Drive, Chicago, Illinois 60606.

Nuveen Fund Advisors, a registered investment adviser, is a subsidiary of Nuveen, LLC (“Nuveen”), the investment management arm of Teachers Insurance and Annuity Association of America (“TIAA”). TIAA is a life insurance company founded in 1918 by the Carnegie Foundation for the Advancement of Teaching and is the companion organization of College Retirement Equities Fund. As of December 31, 2022, Nuveen managed approximately $1.1 trillion in assets, of which approximately $147.7 billion was managed by Nuveen Fund Advisors.

Unless earlier terminated as described below, each Fund’s Investment Management Agreement with Nuveen Fund Advisors will remain in effect until August 1, 2023. Each Investment Management Agreement continues in effect from year to year so long as such continuation is approved at least annually by: (1) the Board or the vote of a majority of the outstanding voting securities of the Fund; and (2) a majority of the Board Members who are not interested persons of any party to the Investment Management Agreement, cast in person at a meeting called for the purpose of voting on such approval. Each Investment Management Agreement may be terminated at any time, without penalty, by either the Fund or Nuveen Fund Advisors upon 60 days’ written notice and is automatically terminated in the event of its assignment, as defined in the 1940 Act.

Pursuant to each Investment Management Agreement, each Fund has agreed to pay an annual management fee for the overall advisory and administrative services and general office facilities provided by Nuveen Fund Advisors. Each Fund’s management fee consists of two components—a complex-level fee, based on the aggregate amount of all eligible fund assets of Nuveen-branded closed- and open-end registered investment companies organized in the United States, and a specific fund-level fee, based only on the amount of assets of such Fund. This pricing structure enables the Funds’ shareholders to benefit from growth in assets within each individual Fund as well as from growth of complex-wide assets managed by Nuveen Fund Advisors.

13

For Senior Income’s, Floating Rate Income Opportunity’s, Short Duration Credit Opportunities’ and the Acquiring Fund’s fiscal year ended July 31, 2022, the effective management fee rates, expressed as a percentage of average total daily managed assets (including assets attributable to leverage), were 0.80%, 0.80%, 0.80% and 0.79%, respectively.

The annual fund-level fee rate for each Fund, payable monthly, is calculated according to the following schedules:

The management fee compensates the Adviser for overall investment advisory and administrative services and general office facilities. Each Fund pays all of its other costs and expenses of its operations, including compensation of its Board Members (other than those affiliated with the Adviser), custodian, transfer agency and dividend disbursing expenses, legal fees, expenses of independent auditors, expenses of repurchasing shares, expenses of issuing any preferred shares, expenses of preparing, printing and distributing shareholder reports, notices, proxy statements and reports to governmental agencies, listing fees and taxes, if any.

Each Fund also pays a complex-level fee to Nuveen Fund Advisors, which is payable monthly and is in addition to the fund-level fee. The complex-level fee is based on the aggregate daily amount of eligible assets for all Nuveen-branded closed- and open-end registered investment companies organized in the United States, as stated in the table below. As of December 31, 2022, the complex-level fee rate for each Fund was 0.1590%.

The annual complex-level fee for each Fund, payable monthly, is calculated by multiplying the current complex-wide fee rate, determined according to the following schedule, by a Fund’s daily managed assets:

14

Sub-Adviser. Nuveen Fund Advisors has selected its wholly owned subsidiary, Nuveen Asset Management, LLC (“Nuveen Asset Management” or the “Sub-Adviser”), located at 333 West Wacker Drive, Chicago, Illinois 60606, to serve as the sub-adviser to each of the Funds pursuant to a sub-advisory agreement between Nuveen Fund Advisors and Nuveen Asset Management (the “Sub-Advisory Agreement”). Nuveen Asset Management, a registered investment adviser, oversees day-to-day operations and manages the investment of the Funds’ assets on a discretionary basis, subject to the supervision of Nuveen Fund Advisors.

For the services provided pursuant to Senior Income’s, Floating Rate Income Opportunity’s, Short Duration Credit Opportunities’ and the Acquiring Fund’s Sub-Advisory Agreements, Nuveen Fund Advisors pays Nuveen Asset Management a portfolio management fee, payable monthly, calculated as set forth below. The sub-advisory fee is calculated as a percentage of the net management fee (net of applicable breakpoints, waivers and reimbursements) paid by the Funds to Nuveen Fund Advisors.

Nuveen Fund Advisors and the Sub-Adviser retain the right to reallocate investment advisory responsibilities and fees between themselves in the future.

A discussion of the basis for the Board’s most recent approval of the current Investment Management Agreement and Sub-Advisory Agreement for Senior Income, Floating Rate Income Opportunity, Short Duration Credit Opportunities and the Acquiring Fund is included in the Funds’ Annual Report for the fiscal year ended July 31, 2022.

Portfolio Management. Subject to the supervision of Nuveen Fund Advisors, Nuveen Asset Management is responsible for execution of specific investment strategies and day-to-day investment operations. Nuveen Asset Management manages the portfolio of each Fund using a team of analysts and a portfolio manager that focuses on a specific group of funds. Scott Caraher and Kevin Lorenz, CFA are portfolio managers of the Target Funds and the Acquiring Fund. Mr. Caraher assumed portfolio management responsibility for Senior Income, Floating Rate Income Opportunity and the Acquiring Fund in 2009 and Short Duration Credit Opportunities in 2011. Mr. Lorenz assumed portfolio management responsibility for each Fund in 2020. Scott Caraher and Kevin Lorenz, CFA, will manage the combined fund upon completion of the Mergers.

Comparative Risk Information

Risk is inherent in all investing. Investing in the Funds involves risk, including the risk that you may receive little or no return on your investment or that you may even lose part or all of your investment. An investment in the Funds is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Before you invest in a Fund, you should consider its principal risks.

Because each Fund invests primarily in senior loans, the principal risks of an investment in each Fund are similar. However, there are differences between the Funds’ investment policies that may affect their comparative risk profiles. Short Duration Credit Opportunities invests at least 80% of its managed assets in below investment grade debt instruments, while Senior Income, Floating Rate Income Opportunity and the Acquiring Fund are not required to invest in below investment grade debt instruments. Senior Income’s investments in non-U.S. issuers are limited to U.S. dollar denominated senior loans, while the other Funds’ investments in non-U.S. issuers may include both U.S. dollar and non-U.S. dollar denominated securities or debt instruments and may also include issuers in emerging markets countries. Floating Rate Income Opportunity and the Acquiring Fund each may not invest more than 20% of their managed assets in securities from the same industry, while Senior Income may not invest more than 25% of its managed assets in borrowers from the same industry and Short Duration Credit Opportunities has no stated policy in this regard.

The principal risks of investing in the Acquiring Fund are described in more detail under the caption “Risk Factors” in the Confidential Information Memorandum accompanying this Proxy Statement as Appendix B (the “Memorandum”).

Comparative Expense Information

The purpose of the Comparative Fee Table is to assist you in understanding the various costs and expenses of investing in common shares of the Funds. The information in the table reflects the fees and expenses of Senior Income, Floating Rate Income Opportunity, Short Duration Credit Opportunities and the Acquiring Fund for the fiscal year ended July 31, 2022 and the pro forma fees and expenses of the combined fund following the Mergers for the twelve months ended July 31, 2022 assuming all Mergers were completed on July 31, 2022 and for each Merger separately.

The assets of the Funds will vary based on market conditions and other factors and may vary significantly during volatile market conditions. The figures in the Example are not necessarily indicative of past or future expenses, and actual expenses may be greater or less than those shown. The Funds’ actual rates of return may be greater or less than the hypothetical 5% annual return shown in the Example.

Example: The following examples illustrate the expenses that a common shareholder would pay on a $1,000 investment that is held for the time periods provided in the table. The examples assume that all dividends and other distributions are reinvested and that Total Annual Expenses remain the same. The examples also assume a 5% annual return. The examples should not be considered a representation of future expenses. Actual expenses may be greater or lesser than those shown.

The examples assume that all dividends and other distributions are reinvested and that Total Annual Expenses remain the same. The examples also assume a 5% annual return. The examples should not be considered a representation of future expenses. Actual expenses may be greater or lesser than those shown.

The examples should not be considered a representation of future expenses. Actual expenses may be greater or lesser than those shown.

19

Average Annual Total Return on Net Asset Value is the combination of changes in common share net asset value, reinvested dividend income at net asset value and reinvested capital gains distributions at net asset value, if any. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending net asset value. The actual reinvestment price for the last dividend declared in the period may often be based on the Fund’s market price (and not its net asset value), and therefore may be different from the price used in the calculation. Average Annual Total Return on Market Value is the combination of changes in the market price per share and the effect of reinvested dividend income and reinvested capital gains distributions, if any, at the average price paid per share at the time of reinvestment. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending market price. The actual reinvestment for the last dividend declared in the period may take place over several days, and in some instances it may not be based on the market price, so the actual reinvestment price may be different from the price used in the calculation. Past performance information is not necessarily indicative of future results.

An investment in the Acquiring Fund may not be appropriate for all investors. The Acquiring Fund is not intended to be a complete investment program and, due to the uncertainty inherent in all investments, there can be no assurance that the Acquiring Fund will achieve its investment objectives. Investors should consider their long-term investment goals and financial needs when making an investment decision with respect to shares of the Acquiring Fund. An investment in the Acquiring Fund is intended to be a long-term investment, and you should not view the Fund as a trading vehicle. Your shares at any point in time may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions, if applicable.

The principal risks of investing in TFP Shares of the Acquiring Fund are described under the caption “Risk Factors” in the Memorandum accompanying this Proxy Statement as Appendix B. An investment in TFP Shares of each Target Fund is also generally subject to these principal risks. The risks and special considerations discussed in the Memorandum should be considered by holders of TFP Shares of each Target Fund in their evaluation of the applicable Merger.

General

Nuveen Fund Advisors, a subsidiary of Nuveen and the Funds’ investment adviser, recommended the Merger proposals as part of an ongoing initiative to streamline Nuveen’s closed-end fund line-up and eliminate overlapping products. Each Fund’s Board considered its Fund’s Merger(s) and determined that the Merger(s) would be in the best interests of its Fund. Based on information provided by Nuveen Fund Advisors, each Target Fund’s Board believes that its Fund’s proposed Merger may benefit the common shareholders of its Fund in a number of ways, including, among other things:

20

With respect to holders of preferred shares of each Target Fund, the Target Fund’s Board considered that, upon the closing of the applicable Merger, holders of any preferred shares outstanding immediately prior to the closing will receive, on a one-for-one basis, newly issued preferred shares of the Acquiring Fund having substantially similar terms as the preferred shares of the applicable Target Fund immediately prior to the closing of the Merger.

Based on information provided by Nuveen Fund Advisors, the Acquiring Fund’s Board considered that the Acquiring Fund also may benefit from economies of scale due to a larger asset base, greater secondary market liquidity and increased portfolio and leverage management flexibility. With respect to holders of preferred shares of the Acquiring Fund, the Acquiring Fund’s Board considered that the outstanding preferred shares of the Acquiring Fund and preferred shares of the Acquiring Fund to be issued in the Mergers would have equal priority with each other as to payment of dividends and distributions of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund.

For these reasons, each Fund’s Board has determined that its Fund’s Merger(s) are in the best interest of its Fund and has approved such Merger(s).

The closing of each Merger is subject to the satisfaction or waiver of certain closing conditions, which include customary closing conditions. In order for a Merger to occur, all requisite shareholder approvals must be obtained at the applicable Fund’s shareholder meetings, and certain other consents, confirmations and/or waivers from various third parties, including the liquidity provider with respect to outstanding preferred shares of the Acquiring Fund and lenders under the Acquiring Fund’s Credit Facility, must also be obtained. Because the closing of each Merger is contingent upon the applicable Target Fund and the Acquiring Fund obtaining such shareholder approvals and satisfying (or obtaining the waiver of) other closing conditions, it is possible that a Merger will not occur even if shareholders of a Fund entitled to vote approve the Merger and a Fund satisfies all of its closing conditions if the other Fund does not obtain its requisite shareholder approvals or satisfy (or obtain the waiver of) its closing conditions. If a Merger is not consummated, the Board of the Target Fund involved in that Merger may take such actions as it deems in the best interests of the Fund, including conducting additional solicitations with respect to the Merger proposals or continuing to operate the Target Fund as a standalone fund. The closing of one Merger is not contingent on the closing of any other Merger.

Terms of the Mergers

General. The Agreement and Plan of Merger by and among the Acquiring Fund, each Target Fund and the Merger Sub (the “Agreement”), in the form attached as Appendix A to this Proxy Statement, sets forth the terms of each Merger and, with respect to each Merger, provides for: (1) the merger of the Target Fund with and into the Merger Sub, with the Merger Sub continuing as the surviving company and the separate legal existence

21

of the Target Fund ceasing for all purposes as of the Effective Time; (2) the conversion of the issued and outstanding common shares of beneficial interest of the Target Fund into newly issued common shares of beneficial interest of the Acquiring Fund, par value $0.01 per share (with cash being received in lieu of any fractional Acquiring Fund common shares), and (3) the conversion of the issued and outstanding TFP Shares of the Target Fund into newly issued TFP Shares of the Acquiring Fund, with a par value of $0.01 per share and a liquidation preference of $1,000 per share. With respect to each Merger, as of the Effective Time, without any further action, the Merger Sub as the surviving company shall (i) succeed to and possess all rights, powers and privileges of the Merger Sub and the Target Fund, and all of the assets and property of whatever kind and character of the Target Fund and the Merger Sub shall vest in the Merger Sub, and (ii) be liable for all of the liabilities and obligations of the Target Fund and the Merger Sub. As soon as practicable following the completion of the Mergers, the Merger Sub will distribute its assets to the Acquiring Fund and the Acquiring Fund will assume the liabilities of the Merger Sub in complete liquidation and dissolution of the Merger Sub under Massachusetts law. The Merger Sub has been formed for the sole purpose of consummating the Mergers and the Merger Sub will not conduct any business prior to the closing of the Mergers, except as necessary to facilitate the Mergers.

As a result of the Mergers, and subsequent distribution of assets to the Acquiring Fund, the assets of the Acquiring Fund and the Target Funds would be combined, and the shareholders of the Target Funds would become shareholders of the Acquiring Fund. The Acquiring Fund will be the accounting survivor of the Mergers.

Each preferred shareholder of a Target Fund will receive the same number of Acquiring Fund TFP Shares having substantially similar terms as the outstanding TFP Shares of such Target Fund held by such preferred shareholder immediately prior to the closing of the Mergers. The aggregate liquidation preference of the Acquiring Fund TFP Shares received in connection with the Mergers will equal the aggregate liquidation preference of a Target Fund’s TFP Shares held immediately prior to the closing of the Mergers. The Acquiring Fund TFP Shares to be issued in connection with the Mergers will have equal priority with each other and with the Acquiring Fund’s other outstanding preferred 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. In addition, the preferred shares of the Acquiring Fund, including any TFP Shares of the Acquiring Fund to be issued in connection with the Mergers, and any borrowings of the Acquiring Fund, will be senior in priority to the Acquiring Fund’s common 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 closing date is expected to be on or about June 5, 2023, or such other date as the parties may agree (the “Closing Date”). Following the Mergers, each Target Fund will terminate its registration as an investment company under the 1940 Act. The Acquiring Fund will continue to operate after the Mergers as a registered closed-end management investment company, with the investment objectives and policies described in this Proxy Statement.

The aggregate net asset value, as of the Valuation Time (as defined below), of the Acquiring Fund common shares received by each Target Fund’s common shareholders in connection with the Mergers will equal the aggregate net asset value of the Target Fund common shares held by shareholders of the Target Fund as of the Valuation Time. Prior to the Valuation Time, the net asset value of each Fund will be reduced by the costs of the Mergers borne by such Fund. See “—Description of Common Shares to Be Issued by the Acquiring Fund; Comparison to Target Funds” for a description of the rights of Acquiring Fund common shareholders. However, no fractional Acquiring Fund common shares will be distributed to a Target Fund’s common shareholders in connection with a Merger. The Acquiring Fund’s transfer agent will aggregate all fractional Acquiring Fund common shares that may be due to a Target Fund’s shareholders as of the Closing Date and will sell the resulting whole shares for the account of holders of all such fractional interests at a value that may be higher or lower than net asset value, and each such holder will be entitled to a pro rata share of the proceeds from such sale. With respect to the aggregation and sale of fractional common shares, the Acquiring Fund’s transfer agent will act directly on behalf of the shareholders entitled to receive fractional shares and will accumulate fractional shares, sell the shares and distribute the cash proceeds net of brokerage commissions, if any, directly to the Target Fund shareholders entitled to receive the fractional shares (without interest and subject to withholding taxes). For

22

federal income tax purposes, Target Fund shareholders will be treated as if they received fractional share interests and then sold such interests for cash in a taxable transaction. The holding period and the aggregate tax basis of the Acquiring Fund shares received by a shareholder, including fractional share interests deemed received by a shareholder, will be the same as the holding period and aggregate tax basis of the Target Fund common shares previously held by the shareholder and exchanged therefor, provided the Target Fund shares exchanged therefor were held as capital assets at the effective time of a Merger. As a result of the Mergers, common shareholders of the Funds will hold a smaller percentage of the outstanding common shares of the combined fund as compared to their percentage holdings of their respective Fund prior to the Mergers and thus, common shareholders will hold reduced percentages of ownership in the larger combined entity than they held in the Acquiring Fund or a Target Fund individually.

Following the Mergers, each preferred shareholder of the Target Funds would own the same number of new Acquiring Fund TFP Shares with the same aggregate liquidation preference as the TFP Shares of the Target Fund held by such shareholder immediately prior to the closing of the Mergers, with substantially similar terms as the outstanding TFP Shares of the Target Fund held by such preferred shareholder immediately prior to the closing of a Merger. As a result of the Mergers, preferred shareholders of the Funds will hold reduced voting percentages of preferred shares in the combined fund than they held in the Acquiring Fund or a Target Fund individually.

The holders of TFP Shares of each Target Fund will receive the following new series of TFP Shares of the Acquiring Fund:

Pursuant to the Agreement, the net asset value per share of each Target Fund and the Acquiring Fund shall be computed as of the close of regular trading on the NYSE on the business day immediately prior to the Closing Date (such time and date referred to herein as the “Valuation Time”) using the valuation procedures of the Nuveen closed-end funds or such other valuation procedures as will be mutually agreed upon by the parties.

Acquiring Fund Common Shares to be Issued. At the effective time of the closing (the “Effective Time”), each Target Fund common share outstanding immediately prior to the Effective Time shall be converted into a number of Acquiring Fund common shares equal to one multiplied by the quotient of the net asset value per share of the Target Fund divided by the net asset value per share of the Acquiring Fund.

Amendments. Under the terms of the Agreement, the Agreement may be amended, modified or supplemented in such manner as may be mutually agreed upon in writing by each Fund affected by the amendment as specifically authorized by such Fund’s Board; provided, however, that following the receipt of shareholder approval of the Agreement with respect to a Merger, no such amendment, modification or supplement may have the effect of changing the provisions for determining the number of Acquiring Fund shares

23

to be issued to a Target Fund’s shareholders under the Agreement with respect to a Merger to the detriment of such shareholders without their further approval.

Conditions. Under the terms of the Agreement, the closing of each Merger is subject to the satisfaction or waiver (if permissible) of the following closing conditions: (1) the requisite approval by the common and preferred shareholders of each Fund of the proposals with respect to the Target Fund’s Merger described in this Proxy Statement, (2) each Fund’s receipt of an opinion of counsel substantially to the effect that the merger of the Target Fund with and into the Merger Sub will qualify as a reorganization under the Code (see “—Material Federal Income Tax Consequences of the Mergers”), (3) the absence of legal proceedings challenging the Mergers, and (4) the Funds’ receipt of certain customary certificates and legal opinions. Additionally, in order for the Mergers to occur, certain other consents, confirmations and/or waivers from various third parties, including the liquidity provider with respect to outstanding preferred shares of the Acquiring Fund and lenders under the Acquiring Fund’s Credit Facility, must also be obtained.

Termination. With respect to each Merger, the Agreement may be terminated by the mutual agreement of the parties, and such termination may be effected by the Chief Administrative Officer, President or any Vice President of each Fund without further action by a Target Fund’s Board or the Acquiring Fund’s Board. In addition, a Fund may at its option terminate the Agreement with respect to its Merger at or before the closing due to: (1) a breach by the non-terminating party of any representation or warranty, or agreement to be performed at or before the closing, if not cured within 30 days of the breach and prior to the closing; (2) a condition precedent to the obligations of the terminating party that has not been met or waived and it reasonably appears that it will not or cannot be met; or (3) a determination by a Target Fund’s Board or the Acquiring Fund’s Board that the consummation of the transactions contemplated by the Agreement is not in the best interests of its respective Fund involved in the Merger(s).

Reasons for the Mergers

Based on the considerations described below, the Board of Trustees of each Target Fund (each, a “Target Board” and collectively, the “Target Boards”), all of whom are not “interested persons,” as defined in the 1940 Act, and the Board of Trustees of the Acquiring Fund (the “Acquiring Board” and together with the Target Boards, the “Boards” and each individually, a “Board”), all of whom are not “interested persons,” as defined in the 1940 Act, have each determined that its Fund’s Merger(s) would be in the best interests of its Fund and that the interests of the existing shareholders of its Fund would not be diluted as a result of such Merger(s). At a meeting held on January 19, 2023 (the “Board Meeting”), each Board approved its Fund’s Merger(s) and recommended that shareholders of its Fund, as applicable, approve such Merger(s).

At and prior to the Board Meeting, including at previous meetings, Nuveen Fund Advisors made presentations and provided the Boards with information relating to the proposed Mergers and alternatives to the proposed Mergers. Prior to approving the Mergers, each Board reviewed the foregoing information with its independent legal counsel and with management, reviewed with independent legal counsel applicable law and its duties in considering such matters and met with independent legal counsel in private sessions without management present. Each Board recognized that Nuveen Fund Advisors, each Fund’s investment adviser, had recommended the Merger proposals as part of an ongoing initiative to streamline Nuveen’s closed-end fund line-up and eliminate overlapping products. Based on the foregoing, the Boards considered the following factors (as applicable), among others, in approving the Mergers and recommending that shareholders of the Funds (as applicable) approve the Mergers:

24

Compatibility of Investment Objectives, Policies and Related Risks. Based on the information presented, the Boards noted that the Funds have similar investment objectives, policies and risks, but there are differences. For example, although each Fund has an investment objective that generally includes providing current income, Short Duration Credit Opportunities’ investment objective also includes providing the potential for capital appreciation. Further, although each Fund invests primarily in senior loans, there are certain policy differences. In its review, based on information provided by Nuveen Fund Advisors, each Board considered the anticipated impact of the Mergers on its Fund’s portfolio, including the expected effect on credit quality, and noted the similarities in portfolio composition and the degree of portfolio overlap among the Funds. The Boards also noted that each Fund may use leverage through a number of methods, including, among other things, through borrowings and the issuance of preferred shares. Moreover, in comparison to the Target Funds, the Target Boards recognized the potential for increased portfolio and leverage management flexibility afforded by the significantly larger asset base of the combined fund. With respect to principal investment risks, while the principal risks of an investment in each Fund would be similar in certain respects because each Fund invests primarily in senior loans, the differences relating to the Funds’ investment policies may affect the comparative risk profiles.

The Boards recognized that the Acquiring Fund has one series of TFP Shares outstanding, which are expected to remain outstanding following the Mergers, and each Target Fund has one series of TFP Shares outstanding. With respect to holders of preferred shares of each Target Fund, the Target Board considered that upon the closing of its Fund’s Merger, holders of any preferred shares outstanding immediately prior to the closing will receive, on a one-for-one basis, newly issued preferred shares of the Acquiring Fund having substantially similar terms to those of the preferred shares of the applicable Target Fund immediately prior to the closing of such Merger.

With respect to the Acquiring Fund, the Acquiring Board considered, based on information provided by Nuveen Fund Advisors, that the Acquiring Fund may benefit from increased portfolio and leverage management flexibility. The Acquiring Board also recognized that the outstanding preferred shares of the Acquiring Fund and any preferred shares of the Acquiring Fund to be issued in the Mergers would have equal priority with each other as to payment of dividends and distributions of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund.

Consistency of Portfolio Management. Each Fund has the same investment adviser and sub-adviser. In addition, each Fund has the same portfolio management team, which will continue to manage the combined fund upon completion of the Mergers. Through the Mergers, the Boards recognized that shareholders would remain invested in a closed-end management investment company that will have greater net assets and the same investment adviser, sub-adviser and portfolio managers.

25

Larger Asset Base of the Combined Fund; Effect of the Mergers on Fees and Expense Ratios. The Boards evaluated the fees and expense ratios of each of the Funds (including estimated expenses of the combined fund following the Mergers). It was anticipated that the Funds will benefit from the larger asset size as fixed costs are shared over a larger asset base. The Target Boards also considered that the fund-level management fee schedule of the Acquiring Fund was the same as that of each Target Fund at each breakpoint level and that, assuming each Merger is completed, the larger asset base of the combined fund may help to achieve fund-level management fee breakpoints. In addition, the Target Boards noted that, assuming each Merger is completed, it was expected that the net operating expenses per common share (i.e., expenses excluding the costs of leverage) of the combined fund would be lower than those of each Target Fund prior to the closing of the Mergers. In addition, the Acquiring Board noted that, assuming each Merger is completed, the net operating expenses per common share (i.e., expenses excluding the costs of leverage) of the combined fund were expected to be lower than those of the Acquiring Fund prior to the closing of the Mergers.

Potential for Improved Secondary Market Trading. While it is not possible to predict trading levels following the Mergers, the Target Boards noted that the Mergers are being proposed, in part, to seek to enhance the secondary trading market for the common shares with respect to the Target Funds. The Target Boards considered that, relative to the Target Funds, the combined fund’s greater share volume may result in greater secondary market liquidity and improved secondary market trading for common shares after the Mergers, which may lead to narrower bid-ask spreads and smaller trade-to-trade price movements. In addition, based on information provided by Nuveen Fund Advisors (including, among other things, average trading discounts calculated over various time periods), the Target Boards considered the potential for a narrower trading discount, relative to the Target Funds, as a result of the larger size of the combined fund and the Acquiring Fund’s common shares trading at a discount that historically has been approximately equal to or lower than that of the Target Funds’ common shares. However, the Target Boards recognized that the past trading record of the common shares of the Acquiring Fund may not necessarily be indicative of how the common shares of the combined fund will trade in the future and that no assurance can be provided regarding the trading discount of the common shares of the combined fund. Further, with respect to the Acquiring Fund, the Acquiring Board noted that such Fund may benefit from greater secondary market liquidity with respect to its common shares due to increased scale.

Anticipated Tax-Free Reorganizations; Capital Loss Carryforwards. Each Merger will be structured with the intention that it qualifies as a tax-free reorganization for federal income tax purposes, and each Fund participating in a Merger will obtain an opinion of counsel substantially to this effect (based on certain factual representations and certain customary assumptions and exclusions). In addition, the Boards considered the impact of the Mergers on the ability to use capital loss carryforwards of the Funds and applicable limitations of federal income tax rules. Further, the Boards considered that, with respect to the Target Funds, significant portfolio sales were not expected to occur solely in connection with the Mergers.

Expected Costs of the Mergers. The Boards considered the terms and conditions of the Mergers, including the estimated costs associated with the Mergers and the allocation of such costs among the Funds. Preferred shareholders will not bear any costs of the Mergers.

Terms of the Mergers and Impact on Shareholders. The terms of the Mergers are intended to avoid dilution of the interests of the existing shareholders of the applicable Funds. In this regard, each Target Board considered that each holder of common shares of its Target Fund will receive common shares of the Acquiring Fund (taking into account any fractional shares to which the shareholder would be entitled) equal in value as of the Valuation Time to the aggregate per share net asset value of that shareholder’s Target Fund common shares held as of the Valuation Time. However, no fractional common shares of the Acquiring Fund will be distributed to the Target Funds’ common shareholders in connection with the Mergers. In lieu of such fractional shares, the Target Funds’ common shareholders will receive cash. As noted above with respect to holders of preferred shares of each Target Fund, holders of any preferred shares outstanding immediately prior to the closing of the

26

applicable Merger will receive, on a one-for-one basis, newly issued preferred shares of the Acquiring Fund having substantially similar terms to those of the preferred shares of the applicable Target Fund immediately prior to the closing of such Merger.

In conjunction with the issuance of additional shares of the Acquiring Fund as described above, the Acquiring Board considered that the Acquiring Fund would receive additional assets and liabilities as a result of each Merger. Further, as noted above, the outstanding preferred shares of the Acquiring Fund and any preferred shares of the Acquiring Fund to be issued in the Mergers would have equal priority with each other as to payment of dividends and distributions of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund.

Effect on Shareholder Rights. The Boards considered that each Fund is organized as a Massachusetts business trust. In this regard, with respect to each Target Fund, there will be no change to shareholder rights under state statutory law.

Alternatives. The Target Boards considered various alternatives to the Mergers, including, among other things, keeping the status quo, liquidating the Target Funds, and merging the Target Funds into an open-end fund. In considering the status quo, the Target Boards considered Nuveen Fund Advisors’ view, among other things, that this option would not provide shareholders with the opportunity to benefit from economies of scale. In considering liquidation, the Target Boards took into account, among other things, that such alternative would be a taxable event and could be potentially disruptive to long-term shareholders. With respect to a merger into an open-end fund, the Target Boards considered, among other things, that based on the information provided by Nuveen Fund Advisors, this option may result in potentially lower earnings over time for Target Fund shareholders and may be disruptive to the acquiring open-end fund’s shareholders. In evaluating the proposed Mergers, the Target Boards considered, among other things, Nuveen Fund Advisors’ view that combining the Target Funds with a larger closed-end fund that also invests primarily in senior loans was an attractive alternative in light of certain potential benefits to shareholders of the Target Funds, as outlined above.

Potential Benefits to Nuveen Fund Advisors and Affiliates. The Boards recognized that the Mergers may result in some benefits and economies of scale for Nuveen Fund Advisors and its affiliates. These may include, for example, a reduction in the level of operational expenses incurred for administrative, compliance and portfolio management services as a result of the elimination of each Target Fund as a separate fund in the Nuveen complex.

Conclusion. Each Board approved the Merger(s) involving its Fund, concluding that each such Merger is in the best interests of its Fund and that the interests of existing shareholders of its Fund will not be diluted as a result of the respective Merger(s).

Capitalization

The following tables set forth the unaudited equity capitalization of the Funds as of November 30, 2022, and the pro-forma combined equity capitalization of the Acquiring Fund as if the Merger(s) had occurred on that date assuming the completion of all Mergers and the completion of each Merger separately.

The table reflects pro forma exchange ratios of approximately 0.58362402, 0.98941510 and 1.47209981 common shares of the Acquiring Fund issued for each common share of Senior Income, Floating Rate Income Opportunity

27

and Short Duration Credit Opportunities, respectively. If the Mergers are consummated, the actual exchange ratios may vary.

28

The table reflects a pro forma exchange ratio of approximately 0.58362402 common shares of the Acquiring Fund issued for each common share of Senior Income. If the Merger is consummated, the actual exchange ratio may vary.

29

The table reflects a pro forma exchange ratio of approximately 0.98941510 common shares of the Acquiring Fund issued for each common share of Floating Rate Income Opportunity. If the Merger is consummated, the actual exchange ratio may vary.

30

The table reflects a pro forma exchange ratio of approximately 1.47209981 common shares of the Acquiring Fund issued for each common share of Short Duration Credit Opportunities. If the Merger is consummated, the actual exchange ratio may vary.

Expenses Associated with the Mergers

Preferred shareholders will not bear any costs of the Mergers. The costs of the Mergers are estimated to be $2,070,000, but the actual costs may be higher or lower than that amount. These costs represent the estimated nonrecurring expenses of the Funds in carrying out their obligations under the Agreement and consist of management’s estimate of professional service fees, printing costs and mailing charges related to the proposed Mergers. Based on the expected benefits of the Mergers to each Fund, each of Senior Income, Floating Rate Income Opportunity, Short Duration Credit Opportunities and the Acquiring Fund is expected to be allocated $705,000, $420,000, $775,000 and $170,000, respectively, of the estimated expenses in connection with the Mergers (0.31%, 0.10%, 0.51% and 0.03%, respectively, of Senior Income’s, Floating Rate Income Opportunity’s, Short Duration Credit Opportunities’ and the Acquiring Fund’s average net assets applicable to common shares for the twelve months ended July 31, 2022). If one or more Mergers are not consummated for any reason, including because the requisite shareholder approvals are not obtained, each of the Funds, and common shareholders of each of the Funds indirectly, will still bear the costs of the Mergers.

31

The Funds have engaged Computershare Fund Services to assist in the solicitation of proxies at an estimated aggregate cost of $7,500 per Fund plus reasonable expenses, which is included in the foregoing estimate.

Dissenting Shareholders’ Rights of Appraisal

Under the charter documents of the Funds, shareholders do not have dissenters’ rights of appraisal with respect to their shares in connection with the Mergers.

Material Federal Income Tax Consequences of the Mergers

As a non-waivable condition to each Fund’s obligation to consummate the Mergers, each Fund will receive a tax opinion from Vedder Price P.C. (which opinion will be based on certain factual representations and certain customary assumptions and exclusions) with respect to its Merger(s) substantially to the effect that, on the basis of the existing provisions of the Code, current administrative rules and court decisions, for federal income tax purposes:

With respect to each Merger, the opinion addressing the federal income tax consequences of the Merger described above will rely on the assumption that the Acquiring Fund TFP Shares received in the Merger, if any,

32

will constitute equity of the Acquiring Fund. In that regard, special tax counsel to the Acquiring Fund will deliver an opinion to the Acquiring Fund, subject to certain representations, assumptions and conditions, substantially to the effect that any Acquiring Fund TFP Shares received in the Merger by the holders of TFP Shares of the Target Fund will qualify as equity of the Acquiring Fund for federal income tax purposes. As a result, distributions with respect to the preferred shares (other than distributions in redemption of preferred shares subject to Section 302(b) of the Code) will generally constitute dividends to the extent of the Acquiring Fund’s allocable current or accumulated earnings and profits, as calculated for federal income tax purposes. Because the treatment of a corporate security as debt or equity is determined on the basis of the facts and circumstances of each case, and no controlling precedent exists for the preferred shares issued in the Mergers, there can be no assurance that the Internal Revenue Service (“IRS”) will not question special tax counsel’s opinion and the Acquiring Fund’s treatment of the preferred shares as equity. If the IRS were to succeed in such a challenge, holders of preferred shares could be characterized as receiving taxable interest income, possibly requiring them to file amended income tax returns and retroactively to recognize additional amounts of ordinary income and pay additional tax, interest and penalties, and the tax consequences of the Mergers could differ significantly from those described in this Proxy Statement.

No opinion will be expressed as to (1) the effect of the Mergers on a Target Fund, the Acquiring Fund, the Merger Sub or any Target Fund shareholder with respect to any asset (including, without limitation, any stock held in a passive foreign investment company as defined in Section 1297(a) of the Code) as to which any gain or loss is required to be recognized under federal income tax principles (i) at the end of a taxable year (or on the termination thereof) or (ii) upon the transfer of such asset regardless of whether such transfer would otherwise be a non-taxable transaction under the Code, (2) the effect of the Mergers under the alternative minimum tax imposed under Section 55 of the Code on a direct or indirect shareholder of a Target Fund that is a corporation, and (3) any other federal tax issues (except those set forth above) and all state, local or non-U.S. tax issues of any kind.

Each opinion will be based on certain factual representations and customary assumptions. The opinion will rely on such representations and will assume the accuracy of such representations. If such representations and assumptions are incorrect, the Merger that is the subject of such opinion may not qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and the Target Fund involved in such Merger and Target Fund shareholders may recognize taxable gain or loss as a result of that Merger.

Opinions of counsel are not binding upon the IRS or the courts and there can be no assurance that the IRS or a court will concur on all or any of the issues discussed above. If the Mergers occur but the IRS or the courts determine that a Merger does not qualify as a “reorganization” within the meaning of Section 368(a) of the Code, the Target Fund involved in such Merger may recognize gain or loss on the transfer of its assets to the Acquiring Fund and/or the deemed distribution of Acquiring Fund shares to its shareholders and each shareholder of that Target Fund would recognize taxable gain or loss equal to the difference between its basis in its Target Fund shares and the fair market value of the shares of the Acquiring Fund it receives.

Each Fund designates distributions to common and preferred shareholders as consisting of particular types of income (such as ordinary income and capital gain) based on each class’s proportionate share of the total distributions paid by the Fund with respect to the year. Additional distributions may be made if necessary. As a result, such distribution could affect the character of the distributions received by holders of TFP Shares with respect to the year in which such distribution occurs for federal income tax purposes.

After the Mergers, the Acquiring Fund’s ability to use a Target Fund’s or the Acquiring Fund’s realized and unrealized pre-Merger capital losses may be limited under certain federal income tax rules applicable to reorganizations of this type. Therefore, in certain circumstances, shareholders may pay federal income tax sooner, or pay more federal income tax, than they would have had the Mergers not occurred. The effect of these potential limitations, however, will depend on a number of factors including the amount of the losses, the amount of gains to be offset, the exact timing of the Mergers and the amount of unrealized capital gains in the Funds at the time of the Mergers.

33

The table below sets forth, as of July 31, 2022 (each Fund’s tax year end), each Fund’s unused capital loss carryforwards available for federal income tax purposes to be applied against future capital gains, if any.

In addition, the shareholders of the Target Funds will receive a proportionate share of any taxable income and gains (after the application of any available capital loss carryforwards) realized by the Acquiring Fund and not distributed to its shareholders prior to the closing of a Merger when such income and gains are eventually distributed by the Acquiring Fund. To the extent the Acquiring Fund sells portfolio investments after the Mergers, the Acquiring Fund may recognize gains or losses (including any built-in gain in the portfolio investments of a Target Fund or the Acquiring Fund that was unrealized at the time of the Mergers), which also may result in taxable distributions to shareholders holding shares of the Acquiring Fund, including former Target Fund preferred shareholders who hold Acquiring Fund preferred shares after the Mergers. As a result, shareholders of the Target Funds and the Acquiring Fund may receive a greater amount of taxable distributions than they would have had the Mergers not occurred.

The foregoing is intended to be only a summary of the principal federal income tax consequences of the Mergers and should not be considered to be tax advice. This description of the federal income tax consequences of the Mergers is made without regard to the particular facts and circumstances of any shareholder. There can be no assurance that the IRS or a court will concur on all or any of the issues discussed above. Shareholders are urged to consult their own tax advisers as to the specific consequences to them of the Mergers, including without limitation the federal, state, local, and non-U.S. tax consequences with respect to the foregoing matters and any other considerations that may be applicable to them.

Shareholder Approval

With respect to each Merger, the Merger is required to be approved by the affirmative vote of the holders of a majority (more than 50%) of a Target Fund’s outstanding common and preferred shares entitled to vote on the matter, voting together as a single class, and by the affirmative vote of the holders of a majority (more than 50%) of a Target Fund’s outstanding preferred shares entitled to vote on the matter, voting together as a single class. Each Merger also is required to be approved by the affirmative vote of the holders of a majority (more than 50%) of the Acquiring Fund’s outstanding preferred shares entitled to vote on the matter, voting together as a single class. Holders of each Target Fund’s common shares are being solicited separately on the foregoing proposal through a separate proxy statement. In addition, under the rules of the NYSE, the Acquiring Fund’s common and preferred shareholders are required to approve the issuance of additional Acquiring Fund common shares in connection with the Mergers—See Proposal 2.

Abstentions and broker non-votes, if any, will have the same effect as a vote against the approval of a Merger. Broker non-votes are shares held by brokers or nominees, typically in “street name,” as to which (1) instructions have not been received from the beneficial owners or persons entitled to vote and (2) the broker or nominee does not have discretionary voting power on a particular matter.

Preferred shareholders of the Funds are separately being asked to approve the Agreement as a “plan of reorganization” under the 1940 Act. Section 18(a)(2)(D) of the 1940 Act provides that the terms of preferred shares issued by a registered closed-end management investment company must contain provisions requiring approval by the vote of a majority of such shares, voting as a class, of any plan of reorganization adversely

34

affecting such shares. Because the 1940 Act makes no distinction between a plan of reorganization that has an adverse effect as opposed to a materially adverse effect, the Funds are seeking approval of the Agreement by the holders of their preferred shares.

The closing of each Merger is subject to the satisfaction or waiver of certain closing conditions, which include customary closing conditions. In order for a Merger to occur, all requisite shareholder approvals must be obtained at the applicable Fund’s shareholder Meeting, and certain other consents, confirmations and/or waivers from various third parties, including the liquidity provider with respect to outstanding preferred shares of the Acquiring Fund and lenders under the Acquiring Fund’s Credit Facility, must also be obtained. Because the closing of each Merger is contingent upon the applicable Target Fund and the Acquiring Fund obtaining such shareholder approvals and satisfying (or obtaining the waiver of) other closing conditions, it is possible that a Merger will not occur even if shareholders of a Fund entitled to vote approve the Merger and a Fund satisfies all of its closing conditions if the other Fund does not obtain its requisite shareholder approvals or satisfy (or obtain the waiver of) its closing conditions. If a Merger is not consummated, the Board of the Target Fund involved in that Merger may take such actions as it deems in the best interests of the Fund, including conducting additional solicitations with respect to the Merger proposals or continuing to operate the Target Fund as a standalone fund. The closing of one Merger is not contingent on the closing of any other Merger.

The TFP Shares of each Fund were issued on a private placement basis to one or a small number of institutional shareholders. To the extent that one or more preferred shareholders of a Fund owns, holds or controls, individually or in the aggregate, all or a significant portion of a Fund’s outstanding preferred shares, the approval by a Fund’s preferred shareholders required for a Merger to occur may turn on the exercise of voting or consent rights by such particular shareholder(s) and its or their determination as to the favorable view of the Merger with respect to its or their interests. The Funds exercise no influence or control over the determinations of such shareholders with respect to a Merger; there is no guarantee that such shareholders will vote to approve a Merger proposal.

Description of Common Shares to Be Issued by the Acquiring Fund; Comparison to Target Funds

General

As a general matter, the common shares of the Acquiring Fund and the Target Funds have equal voting rights and equal rights with respect to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up of the affairs of their Fund and have no preemptive, conversion or exchange rights, except as the Trustees may authorize, or rights to cumulative voting. Holders of whole common shares of each Fund are entitled to one vote per share on any matter on which they are entitled to vote, while each fractional share entitles its holder to a proportional fractional vote. Furthermore, the provisions set forth in each Fund’s declaration of trust and by-laws include, among other things, substantially identical super-majority voting provisions and other anti-takeover provisions, as described under “Additional Information About the Acquiring Fund—Certain Provisions in the Acquiring Fund’s Declaration of Trust and By-Laws.” The full text of each Fund’s declaration of trust and by-laws are on file with the SEC.

The Acquiring Fund’s declaration of trust authorizes an unlimited number of common shares, par value $0.01 per share. If the Mergers are consummated, the Acquiring Fund will issue additional common shares on the Closing Date to each Target Fund based on the relative per share net asset value of the Acquiring Fund and the aggregate net assets of each Target Fund that are transferred in connection with the Mergers, in each case as of the Valuation Time. The value of the Acquiring Fund’s net assets will be calculated net of the liquidation preference (including accumulated and unpaid dividends) of all of the Acquiring Fund’s outstanding preferred shares.

The terms of the Acquiring Fund common shares to be issued pursuant to the Mergers will be identical to the terms of the Acquiring Fund common shares that are then outstanding. The Acquiring Fund common shares,

35

when issued, will be fully paid and non-assessable except as described under “Summary Description of Massachusetts Business Trusts” below.

Distributions

So long as preferred shares are outstanding, the Acquiring Fund may not declare a dividend or distribution to common shareholders (other than a dividend in common shares of the Fund) or purchase outstanding common shares unless all accumulated dividends on preferred shares have been paid and unless the asset coverage, as defined in the 1940 Act, with respect to its preferred shares at the time of the declaration of such dividend or distribution or at the time of such purchase would be at least 200% after giving effect to the dividend or distribution or purchase price. In addition, the Acquiring Fund may not declare or make payment of a dividend or distribution to common shareholders (other than a dividend in common shares of the Fund) or purchase outstanding common shares unless, at the time of the declaration or making of such dividend or distribution or at the time of such purchase, the Acquiring Fund is in compliance with certain asset coverage requirements, and no event of default exists or would occur, under the Credit Facility.

Affiliated Brokerage and Other Fees

None of the Target Funds or the Acquiring Fund paid brokerage commissions within the last fiscal year to (i) any broker that is an affiliated person of such Fund or an affiliated person of such person, or (ii) any broker an affiliated person of which is an affiliated person of such Fund, the Adviser, or the Sub-Adviser of such Fund.

Description of TFP Shares to Be Issued by the Acquiring Fund

If any of the Mergers take place, the Acquiring Fund will issue TFP Shares (“New TFP Shares”) pursuant to the Agreement if TFP Shares of the merging Target Fund are outstanding immediately prior to the closing. TFP Shares of the Target Funds are subject to redemption in accordance with the respective Target Fund’s statement establishing and fixing the rights and preferences of TFP Shares. The following description applies if New TFP Shares are issued in the Mergers.

The terms of the New TFP Shares of the applicable series will be substantially similar, as of the time of the closing of the Merger, to the terms of the TFP Shares of the applicable Target Fund outstanding immediately prior to the closing of the Merger. The aggregate liquidation preference of the New TFP Shares to be received in the Merger, if any, will equal the aggregate liquidation preference of the applicable Target Fund’s TFP Shares held immediately prior to the closing of the Merger. The economic terms of any New TFP Shares likely may not be the same as the terms of the outstanding TFP Shares of the Acquiring Fund. The number of TFP Shares of a Target Fund currently outstanding may change prior to its Merger due to market or other conditions. See also “Additional Information About the Acquiring Fund—Description of Outstanding Acquiring Fund Series A TFP Shares.”

The Acquiring Fund currently expects that the New TFP Shares issued in connection with the Senior Income Fund Merger will be designated “Series B TFP Shares,” the New TFP Shares issued in connection with the Floating Rate Income Opportunity Merger will be designated “Series C TFP Shares” and the New TFP Shares issued in connection with the Short Duration Credit Opportunities Merger will be designated “Series D TFP Shares.”

The New TFP Shares of each series will be senior in priority to the Acquiring Fund’s common shares as to the payment of dividends and as to the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund. The New TFP Shares of each series will have equal priority with the other preferred shares of the Acquiring Fund, including the Acquiring Fund’s outstanding TFP Shares, any other New TFP Shares to be issued by the Acquiring Fund in the Mergers and any other preferred shares that the Acquiring Fund may issue in the future, as to the payment of dividends and as to distribution of assets upon dissolution,

36

liquidation or winding up of the affairs of the Acquiring Fund. The rights of lenders under the Credit Facility and any other creditors to receive payments of interest on and repayments of principal of any borrowings are senior to the rights of holders of preferred shares, including the existing TFP Shares of the Acquiring Fund and any New TFP Shares, and common shares with respect to the payment of dividends and as to distribution of assets upon dissolution, liquidation or winding up of the affairs of the Acquiring Fund.

New Series B TFP Shares

The TFP Shares of Senior Income are (and the new Series B TFP Shares will be) in the “Variable Rate Mode.” The Variable Rate Mode for the TFP Shares of Senior Income currently ends on October 2, 2023, subject to early transition to a new mode, or scheduled extension or transition to a new mode. A new mode may provide for the modification of the economic terms of the TFP Shares. Modified terms for a new mode may include provisions with respect to (but not limited to) optional tender provisions, mandatory tender provisions, a liquidity facility or other credit enhancement, mandatory purchase provisions, the dividend rate setting provisions (including as to any maximum rate), and, if the dividend may be determined by reference to an index, formula or other method, the manner in which it will be determined and redemption provisions.

Holders of the Series B TFP Shares will be entitled to receive cash dividends when, as and if declared by the Acquiring Fund’s Board. The amount of dividends per Series B TFP Share will equal the sum of dividends accumulated for each day but not yet paid during the relevant monthly dividend period.

The amount of dividends will be calculated monthly based on an index rate equal to one-month Term SOFR or another index plus an applicable spread. The applicable spread will be subject to adjustment in certain circumstances, including a change in the credit rating assigned to the Series B TFP Shares. The dividend rate shall in no circumstances exceed 15% per year.

The Series B TFP Shares will be subject to optional and mandatory redemption by the Fund in certain circumstances.

The Acquiring Fund will be obligated to redeem the Series B TFP Shares on the term redemption date unless earlier redeemed or repurchased by the Acquiring Fund, at a redemption price per share equal to the liquidation preference per share ($1,000) plus any accumulated but unpaid dividends (whether or not earned or declared). The outstanding TFP Shares of Senior Income have a term redemption date of November 1, 2030. The new Series B TFP Shares will have the same term redemption date as the corresponding Senior Income TFP Shares.

During the Variable Rate Mode for the Series B TFP Shares, in the event the Acquiring Fund fails to comply with asset coverage and/or effective leverage ratio requirements and any such failure is not cured within the applicable cure period, the Acquiring Fund may become obligated to redeem such number of preferred shares as are necessary to achieve compliance with such requirements. Also, during the Variable Rate Mode for the Series B TFP Shares, the Acquiring Fund will be obligated to redeem all of the outstanding Series B TFP Shares in the event a mode transition is initiated and a failed transition occurs, if such failure is not cured within the applicable cure period.

Series B TFP Shares also may be redeemed in whole at any time or in part from time to time at the option of the Acquiring Fund at a redemption price per share equal to the liquidation preference per share plus any accumulated but unpaid dividends (whether or not earned or declared).

New Series C TFP Shares

The TFP Shares of Floating Rate Income Opportunity are (and the new Series C TFP Shares will be) in the “Variable Rate Mode.” The Variable Rate Mode for the TFP Shares of Floating Rate Income currently ends on November 2, 2023, subject to early transition to a new mode, or scheduled extension or transition to a new mode. A new mode may provide for the modification of the economic terms of the TFP Shares. Modified terms

37

for a new mode may include provisions with respect to (but not limited to) optional tender provisions, mandatory tender provisions, a liquidity facility or other credit enhancement, mandatory purchase provisions, the dividend rate setting provisions (including as to any maximum rate), and, if the dividend may be determined by reference to an index, formula or other method, the manner in which it will be determined and redemption provisions.

Holders of the Series C TFP Shares will be entitled to receive cash dividends when, as and if declared by the Acquiring Fund’s Board. The amount of dividends per Series C TFP Share will equal the sum of dividends accumulated for each day but not yet paid during the relevant monthly dividend period.

The amount of dividends will be calculated monthly based on an index rate equal to one-month Term SOFR or another index plus an applicable spread. The applicable spread will be subject to adjustment in certain circumstances, including a change in the credit rating assigned to the Series C TFP Shares. The dividend rate shall in no circumstances exceed 15% per year.

The Series C TFP Shares will be subject to optional and mandatory redemption by the Fund in certain circumstances.

The Acquiring Fund will be obligated to redeem the Series C TFP Shares on the term redemption date unless earlier redeemed or repurchased by the Acquiring Fund, at a redemption price per share equal to the liquidation preference per share ($1,000) plus any accumulated but unpaid dividends (whether or not earned or declared).The outstanding TFP Shares of Floating Rate Income Opportunity have a term redemption date of December 1, 2030. The new Series C TFP Shares will have the same term redemption date as the corresponding Floating Rate Income Opportunity TFP Shares.

New Series D TFP Shares

The TFP Shares of Short Duration Credit Opportunities are (and the new Series D TFP Shares will be) in the “Variable Rate Demand Mode.” The Variable Rate Demand Mode for the TFP Shares of Short Duration Credit Opportunities currently ends on November 1, 2029, subject to early transition to a new mode. A new mode may provide for the modification of the economic terms of the TFP Shares. Modified terms for a new mode may include provisions with respect to (but not limited to) optional tender provisions, mandatory tender provisions, a liquidity facility or other credit enhancement, mandatory purchase provisions, the dividend rate setting provisions (including as to any maximum rate), and, if the dividend may be determined by reference to an index, formula or other method, the manner in which it will be determined and redemption provisions.

Holders of the Series D TFP Shares will be entitled to receive cash dividends when, as and if declared by the Acquiring Fund’s Board. The amount of dividends per Series D TFP Share will equal the sum of dividends accumulated for each day but not yet paid during the relevant monthly dividend period.

The Series D TFP Shares will pay an adjustable dividend rate set weekly by a remarketing agent. Holders of the Series D TFP Shares will have the right to give notice on any business day to tender the securities for

38

remarketing in seven days. The Series D TFP Shares also will be subject to a mandatory tender for remarketing upon the occurrence of certain events, such as a mode change or the non-payment of dividends by the Acquiring Fund. Should a remarketing be unsuccessful, the dividend rate will reset to a maximum rate as defined in the governing documents of the Series D TFP Shares. The dividend rate shall in no circumstances exceed 15% per year.

The Series D TFP Shares have the benefit of an unconditional demand feature pursuant to a purchase agreement provided by a bank acting as liquidity provider to ensure full and timely repayment of the liquidation preference amount plus any accumulated and unpaid dividends to holders upon the occurrence of certain events. The purchase agreement for the Series D TFP Shares will require the liquidity provider to purchase from holders all outstanding Series D TFP Shares tendered for sale that were not successfully remarketed. The liquidity provider also must purchase all outstanding Series D TFP Shares prior to termination of the purchase agreement for such series, including by reason of the failure of the liquidity provider to maintain the requisite level of short-term ratings, if the Acquiring Fund has not obtained an alternate purchase agreement before the termination date.

The obligation of the liquidity provider for the Series D TFP Shares to purchase the outstanding Series D TFP Shares pursuant to the purchase agreement for such series will run to the benefit of the holders of the Series D TFP Shares and is unconditional and irrevocable, and as such the short-term ratings assigned to the Series D TFP Shares will be directly linked to the short-term creditworthiness of the liquidity provider. The liquidity provider for the Series D TFP Shares will enter into a purchase agreement with respect to the Series D TFP Shares, subject to periodic extension by agreement with the Acquiring Fund.

The Series D TFP Shares will be subject to optional and mandatory redemption by the Fund in certain circumstances.

The Acquiring Fund will be obligated to redeem the Series D TFP Shares on the term redemption date unless earlier redeemed or repurchased by the Acquiring Fund, at a redemption price per share equal to the liquidation preference per share ($1,000) plus any accumulated but unpaid dividends (whether or not earned or declared). The outstanding TFP Shares of Short Duration Credit Opportunities have a term redemption date of November 1, 2029. The new Series D TFP Shares will have the same term redemption date as the corresponding Short Duration Credit Opportunities TFP Shares.

The Acquiring Fund will have an obligation to redeem, at a redemption price equal to $1,000 per share plus accumulated but unpaid dividends thereon (whether or not earned or declared) until, but excluding, the date fixed by the Board for redemption, Series D TFP Shares purchased by the liquidity provider pursuant to its obligations under the purchase agreement if the liquidity provider continues to be the beneficial owner for a period of six months and such shares cannot be successfully remarketed. The Acquiring Fund also will redeem, at a redemption price equal to the liquidation preference per share plus accumulated but unpaid dividends thereon (whether or not earned or declared) until, but excluding, the date fixed by the Board for redemption, such number of preferred shares as is necessary to achieve compliance, if the Acquiring Fund fails to maintain the minimum asset coverage required under the 1940 Act and the Acquiring Fund’s fee agreement with the liquidity provider for the Series D TFP Shares, and such failure is not cured by the applicable cure date.

Series D TFP Shares also may be redeemed in whole at any time or in part from time to time at the option of the Acquiring Fund at a redemption price per share equal to the liquidation preference per share plus any accumulated but unpaid dividends (whether or not earned or declared).

Summary Description of Massachusetts Business Trusts

The following description is based on relevant provisions of applicable Massachusetts law and each Fund’s governing documents. This summary does not purport to be complete and we refer you to applicable Massachusetts law and each Fund’s operative documents.

General. Each Fund is a Massachusetts business trust. A fund organized as a Massachusetts business trust is governed by the trust’s declaration of trust or similar instrument, and its by-laws (its “governing documents”).

39

Massachusetts law allows the trustees of a business trust to set the terms of a fund’s governance in its governing documents. All power and authority to manage the fund and its affairs generally reside with the trustees, and shareholder voting and other rights are limited to those provided to the shareholders in the fund’s governing documents.

Because Massachusetts law governing business trusts provides more flexibility compared to typical state corporate statutes, the Massachusetts business trust is a common form of organization for closed-end funds. However, some consider it less desirable than other entities because it relies on the terms of the applicable declaration of trust and by-laws and judicial interpretations rather than statutory provisions for substantive issues, such as the personal liability of shareholders and trustees, and does not provide the level of certitude that corporate laws or newer statutory trust laws, such as those of Delaware, provide.

Shareholders of a Massachusetts business trust are not afforded the statutory limitation of personal liability generally afforded to shareholders of a corporation from the trust’s liabilities. Instead, the declaration of trust of a fund organized as a Massachusetts business trust typically provides that a shareholder will not be personally liable, and further provides for indemnification to the extent that a shareholder is found personally liable, for the fund’s acts or obligations. The declaration of trust of each Fund contains such provisions.

Similarly, the trustees of a Massachusetts business trust are not afforded statutory protection from personal liability for the obligations of the trust. However, courts in Massachusetts have recognized limitations of a trustee’s personal liability in contract actions for the obligations of a trust contained in the trust’s declaration of trust, and declarations of trust may also provide that trustees may be indemnified out of the assets of the trust to the extent held personally liable. The declaration of trust of each Fund contains such provisions.

The Funds

Each Fund is organized as a Massachusetts business trust and is governed by its declaration of trust and by-laws. Under the declaration of trust of each Fund, any determination as to what is in the interests of the Fund made by the trustees in good faith is conclusive, and in construing the provisions of the declaration of trust, there is a presumption in favor of a grant of power to the trustees. Further, the declaration of trust provides that certain determinations made in good faith by the trustees are binding upon the Fund and all shareholders, and shares are issued and sold on the condition and understanding, evidenced by the purchase of shares, that any and all such determinations will be so binding. The by-laws of each Fund provide that each shareholder of the Fund, by virtue of having become a shareholder, shall be held to have expressly assented and agreed to be bound by the terms of the Fund’s governing documents. The Funds’ declaration of trusts are substantially the same, and the Funds have adopted the same by-laws. The following is a summary of some of the key provisions of the Funds’ governing documents.

Shareholder Voting. The declaration of trust of each Fund limits shareholder voting to certain enumerated matters, including certain amendments to the declaration of trust, the election of trustees if required by the 1940 Act, the merger or consolidation of the Fund with any corporation or a reorganization or sales of assets in certain circumstances and matters required to be voted on by the 1940 Act, or, for Senior Income, a recapitalization of the Fund (under certain circumstances) and, for each Fund, with respect to such additional matters relating to the Fund as the trustees may consider necessary or desirable.

Meetings of shareholders may be called by the trustees and by the written request of shareholders owning at least 10% of the outstanding shares entitled to vote. The holders of a majority (more than 50%) of the voting power of the shares of beneficial interest of the Fund entitled to vote at a meeting will constitute a quorum for the transaction of business. Notwithstanding the foregoing, when the holders of preferred shares are entitled to elect any of a Fund’s trustees by class vote of such holders, the holders of thirty-three and one-third percent (33 1/3%) of the preferred shares entitled to vote at a meeting shall constitute a quorum for the purpose of such an election. Unless other voting provisions contained in the Fund’s governing documents or the 1940 Act apply, the

40

affirmative vote of the holders of a majority (more than 50%) of the shares present in person or by proxy and entitled to vote at a meeting of shareholders at which a quorum is present is required to approve a matter. The governing documents require a super-majority vote in certain circumstances with respect to a merger, consolidation or dissolution of or sale of substantially all of the assets by, the Fund, or its conversion to an open-end investment company, unless such transaction has been approved by two-thirds of the Trustees, and that the affirmative vote of a majority (more than 50%) of the shares outstanding and entitled to vote is required to elect trustees in a “contested election” (i.e., an election in which the number of trustees nominated in accordance with the by-laws exceeds the number of trustees to be elected), but that a plurality vote applies in an uncontested election.

The by-laws of each Fund provide that common shares held by a shareholder who obtains beneficial ownership of common shares in a “Control Share Acquisition” shall have the same voting rights as other common shares only to the extent authorized by the Fund’s shareholders (the “Control Share Provision”). Such authorization shall require the affirmative vote of the holders of a majority (more than 50%) of the shares of the Fund entitled to vote in the election of trustees, excluding Interested Shares. Interested Shares include shares held by Fund officers and any person who has acquired common shares in a Control Share Acquisition. The by-laws define a “Control Share Acquisition,” subject to various conditions and exceptions, generally to mean an acquisition of common shares that would give the beneficial owner, upon the acquisition of such shares, the ability to exercise voting power, but for the Control Share Provision, in the election of trustees (except for any elections of trustees by holders of preferred shares voting as a separate class) in any one of the following ranges: (i) one-tenth or more, but less than one-fifth of all voting power; (ii) one-fifth or more, but less than one-third of all voting power; (iii) one-third or more, but less than a majority of all voting power; or (iv) a majority or more of all voting power. For this purpose, all common shares acquired by a person within ninety days before or after the date on which such person acquires shares that result in a Control Share Acquisition, and all common shares acquired by such person pursuant to a plan to make a Control Share Acquisition, shall be deemed to have been acquired in the same Control Share Acquisition. Subject to various conditions and procedural requirements, including the delivery of a “Control Share Acquisition Statement” to the Fund setting forth certain required information, a shareholder who obtains or proposes to obtain beneficial ownership of common shares in a Control Share Acquisition generally may request a vote of shareholders to approve the authorization of voting rights of such shareholder with respect to such shares. See “General Information—Additional Information About the Solicitation” at page 110 for a description of certain legal matters with respect to the Control Share Provision.

Shareholder Meetings. Meetings of shareholders may be called by the trustees and must be called upon the written request of shareholders entitled to cast at least 10% of all votes entitled to be cast at the meeting. Shareholder requests for special meetings are subject to various requirements under each Fund’s by-laws, including as to the specific form of, and information required in, a shareholder’s request to call such a meeting. A shareholder may request a special meeting only to act on a matter upon which such shareholder is entitled to vote under the terms of the Fund’s governing documents, and shareholders may not request special meetings for the purpose of electing trustees.

The by-laws of each Fund authorize the trustees or the chair of a shareholder meeting to adopt rules, regulations and procedures appropriate for the proper conduct of the meeting, which may include (i) the establishment of an agenda or order of business for the meeting; (ii) the determination of when the polls shall open and close for any given matter to be voted on by the shareholders present or represented at the meeting; (iii) rules and procedures for maintaining order at the meeting and the safety of those present; (iv) limitations on attendance at and participation in the meeting by shareholders, their duly authorized and constituted proxies or such other persons as the chair of the meeting shall determine; (v) restrictions on entry to the meeting after the time fixed for the commencement thereof; (vi) limitations on the time allotted to questions or comments by shareholders; and (vii) the extent to which, if any, other participants are permitted to speak.

The by-laws of each Fund establish qualification criteria applicable to prospective trustees and require that advance notice be given to the Fund in the event a shareholder desires to nominate a person for election to

41

the Board or to transact any other business at a meeting of shareholders. Any notice by a shareholder must be accompanied by certain information as required by the by-laws. No shareholder proposal will be considered at any meeting of shareholders of a Fund if such proposal is submitted by a shareholder who does not satisfy all applicable requirements set forth in the by-laws, and unless otherwise required by applicable law, no matter may be considered at or brought before any meeting of shareholders unless such matter has been deemed a proper matter for shareholder action by certain officers of the Fund or by at least sixty-six and two-thirds percent (66 2/3%) of the trustees.

Election and Removal of Trustees. The declaration of trust of each Fund provides that the trustees determine the size of the Board, subject to a minimum and a maximum number. Subject to the provisions of the 1940 Act, the declaration of trust also provides that vacancies on the Board may be filled by the remaining trustees. A trustee may be removed only for cause and only by action of at least two-thirds of the remaining trustees or by action of at least two-thirds of the outstanding shares of the class or classes that elected such trustee. The by-laws of each Fund establish qualification requirements applicable to any person who is recommended, nominated, elected, appointed, qualified or seated as a trustee.

Pursuant to each Fund’s by-laws, the Fund’s Board is divided into three classes (Class I, Class II and Class III) with staggered multi-year terms, and typically only the members of one of the three classes stand for election each year. The staggered board structure could delay for up to two years the election of a majority of the Board of each Fund. The board structure of the Acquiring Fund will remain in place following the closing of the Mergers.

Issuance of Shares. Under the declaration of trust of each Fund, the trustees are permitted to issue an unlimited number of shares for such consideration and on such terms as the trustees may determine. Shareholders are not entitled to any preemptive rights or other rights to subscribe to additional shares, except as the trustees may determine. Shares are subject to such other preferences, conversion, exchange or similar rights, as the trustees may determine.

Classes. The declaration of trust of each Fund gives broad authority to the trustees to establish classes or series in addition to those currently established and to determine the rights and preferences, conversion rights, voting powers, restrictions, limitations, qualifications or terms or conditions of redemptions of the shares of the classes or series. The trustees are also authorized to terminate a class or series without a vote of shareholders under certain circumstances.

Amendments to Governing Documents. Amendments to the declaration of trust generally require the consent of shareholders owning more than 50% of shares entitled to vote, voting in the aggregate. Certain amendments may be made by the trustees without a shareholder vote, and any amendment to the voting requirements contained in the declaration of trust requires the approval of two-thirds of the outstanding common shares and preferred shares, if any, entitled to vote, voting in the aggregate and not by class except to the extent that applicable law or the declaration of trust may require voting by class. Each Fund’s by-laws may be amended or repealed, or new by-laws may be adopted, by a vote of a majority of the trustees. The by-laws of each Fund may not be amended by shareholders.

Shareholder, Trustee and Officer Liability. The declaration of trust of each Fund provides that shareholders have no personal liability for the acts or obligations of the Fund and requires the Fund to indemnify a shareholder from any loss or expense arising solely by reason of his or her being or having been a shareholder and not because of his or her acts or omissions or for some other reason. In addition, each declaration of trust provides that the Fund will assume the defense of any claim against a shareholder for personal liability at the request of the shareholder. Similarly, each declaration of trust provides that any person who is a trustee, officer or employee of the Fund is not personally liable to any person in connection with the affairs of the Fund, other than to the Fund and its shareholders arising from such trustee’s, officer’s or employee’s bad faith, willful misfeasance, gross negligence or reckless disregard for his or her duty. Each declaration of trust further provides for indemnification

42

of such persons and advancement of the expenses of defending any such actions for which indemnification might be sought. Each declaration of trust also provides that the trustees may rely in good faith on expert advice.

Forum Selection. Each Fund’s by-laws provide that, unless the Fund consents in writing to the selection of an alternative forum, and except for certain claims brought under the federal securities laws, the sole and exclusive forum for any shareholder or group of shareholders to bring (i) any derivative action or proceeding brought on behalf of the Fund, (ii) any action asserting a claim for breach of any duty owed by a trustee or officer or other employee of a Fund to the Fund or to the Fund’s shareholders, (iii) any action asserting a claim arising pursuant to Massachusetts business trust law or the Fund’s governing documents, and (iv) any other action asserting a claim governed by the internal affairs doctrine, shall be within the United States District Court for the District of Massachusetts (Boston Division) or, to the extent such court does not have jurisdiction, the Business Litigation Session of the Massachusetts Superior Court in Suffolk County. Each Fund’s by-laws further provide that in any such covered action there is no right to a jury trial and the right to a jury trial is expressly waived to the fullest extent permitted by law.

Derivative and Direct Claims of Shareholders. Each Fund’s by-laws contain provisions regarding derivative and direct claims of shareholders. Massachusetts has what is commonly referred to as a “universal demand statute,” which requires that a shareholder make a written demand on the board, requesting the trustees to bring an action, before the shareholder is entitled to bring or maintain a derivative action in the right of or name of or on behalf of the trust. Under the Massachusetts statute, a shareholder whose demand has been refused by the trustees may bring the claim only if the shareholder demonstrates to a court that the trustees’ decision not to pursue the requested action was not a good faith exercise of their business judgment on behalf of the Fund. The by-laws of each Fund largely incorporate the substantive elements of the Massachusetts statute and establish procedures for shareholders to bring derivative actions and for the Board to consider shareholder demands that the Fund commence a suit. In addition, the by-laws of each Fund distinguish direct actions from derivative claims and prohibit the latter from being brought directly by a shareholder.
