IMPORTANT NEWS FOR FUND SHAREHOLDERS

While we encourage you to read the full text of the enclosed Proxy Statement, for your convenience, we have provided a brief overview of these materials.

Questions and Answers

i

The Russell 1000 Growth Index (the "Index"), the Fund's performance benchmark, is becoming increasingly concentrated in a small number of large-cap technology companies. As of December 31, 2025, the five largest stocks by weight in the Index were: Nvidia (12.26%), Apple (10.51%), Microsoft (9.69%), Broadcom (4.84%) and Amazon (4.72%). The Fund is not currently permitted to invest in securities at a level reflecting the current market, as represented by the composition of the Index, without exceeding the limits permitted for a "diversified" fund.

Franklin Templeton Fund Adviser, LLC ("FTFA"), the Fund's investment manager, and ClearBridge Investments, LLC ("ClearBridge"), the Fund's subadviser, believe that changing the Fund's classification to "non-diversified" will benefit the Fund by giving it greater flexibility to hold larger positions in certain companies, which will better allow the Fund to take more meaningful positions in securities in which ClearBridge has strong investment convictions and could better allow the Fund to meet its investment objective.

ii

Shareholders should note that to the extent the Fund invests its assets in a smaller number of issuers, the Fund will be more susceptible to negative events affecting those issuers than a "diversified" fund. Investing a larger percentage of the Fund's assets in any one issuer could increase the Fund's risk of loss and its share price volatility because the value of its shares would be more susceptible to adverse events affecting that issuer. If the Fund takes a larger position in an issuer that subsequently has an adverse return, the Fund may have a greater loss than it would have had if ClearBridge had invested Fund assets in a larger number of issuers. ClearBridge will use this increased investment flexibility to take larger positions in the securities of fewer issuers when it believes that doing so could benefit the Fund. If the Proposal is approved, trading costs to implement these changes to the Fund's portfolio (that is, to take larger positions in certain issuers) are estimated to be in the range of approximately $20,000. Such trading costs, which would principally reflect brokerage fees, would be borne by the Fund.

PROXY STATEMENT

This Proxy Statement is furnished in connection with the solicitation by the Board of Trustees (the "Board" and each Board member, a "Trustee") of ClearBridge Large Cap Growth Fund (the "Fund") of proxies to be voted at a special meeting of shareholders of the Fund (the "Meeting") which will be held exclusively online via live webcast on April 7, 2026 at 1:00 p.m. Eastern time and at any and all adjournments or postponements thereof. The Meeting will be held for the purposes set forth in the accompanying Notice of the Meeting. This Proxy Statement and the accompanying materials are being mailed to shareholders of the Fund on or about January 30, 2026.

The Fund is organized as a series of Legg Mason Investment Trust, a Maryland statutory trust (the "Trust"). The Trust is registered as an investment company.

Shareholders of record of the Fund at the close of business on January 21, 2026 (the "Record Date") are entitled to vote at the Meeting. As of the close of business on the Record Date, the Fund had the number of shares outstanding set forth in Appendix A. The total net assets of the Fund as of the close of business on the Record Date are set forth in Appendix A

Shareholders are entitled to one vote for each dollar of net asset value of the Fund represented by the shareholder's shares of the Fund. Shareholders will vote as a single class on the Proposals. Shareholders are not entitled to any appraisal rights as the result of any Proposal to be considered at the Meeting.

Please complete EACH proxy card you receive, or if you vote by telephone or over the Internet, please vote on EACH Proposal. If you vote by telephone or over the Internet, you may be asked to enter a

1

unique code that has been assigned to you, which is printed on your proxy card(s). This code is designed to confirm your identity, provide access into the voting sites and confirm that your instructions are properly recorded.

All properly executed proxies received prior to the Meeting will be voted at the Meeting. On the matters coming before the Meeting as to which a shareholder has specified a choice on that shareholder's proxy, the shares will be voted accordingly.

If a proxy is properly executed and returned and no choice is specified with respect to one or more Proposals, the shares will be voted "FOR" each such Proposal. Shareholders who execute proxies or provide voting instructions by telephone or the Internet may revoke them with respect to any or all Proposals at any time before a vote is taken on a Proposal by filing with the Fund a written notice of revocation (addressed to the Secretary of the Fund at the principal executive offices of the Fund at the address above), by delivering a duly executed proxy bearing a later date or by attending the Meeting and voting in person, in all cases prior to the exercise of the authority granted in the proxy card. Merely attending the Meeting, however, will not revoke any previously executed proxy. If you hold shares through a bank or other intermediary, please consult your bank or intermediary regarding your ability to revoke voting instructions after such instructions have been provided.

Annual reports are sent to shareholders of record of the Fund following the Fund's fiscal year end. The Fund's fiscal year end is November 30. The Fund will furnish, without charge, a copy of its annual report and most recent semi-annual report succeeding the annual report, if any, to a shareholder upon request. Such requests should be directed to the Fund at One Madison Avenue, 17^th Floor, New York, New York 10010 or by calling toll free at 877-6LM-FUND/656-3863. Copies of annual and semi-annual reports of the Fund are also available on the EDGAR Database on the Securities and Exchange Commission's Internet site at www.sec.gov.

2

Please note that only one annual or semi-annual report or Proxy Statement may be delivered to two or more shareholders of the Fund who share an address, unless the Fund has received instructions to the contrary. To request a separate copy of an annual report or the Proxy Statement, or for instructions as to how to request a separate copy of these documents or as to how to request a single copy if multiple copies of these documents are received, shareholders should contact the Fund at the address and phone number set forth above.

Vote Required and Manner of Voting Proxies

A quorum of shareholders is required to take action at the Meeting. The holders of outstanding shares entitled to vote and present in person or by proxy representing thirty percent (30%) of the voting power of the Fund shall constitute a quorum. For the purposes of establishing whether a quorum is present, all shares present and entitled to vote shall be counted. A quorum consists of 30% of the voting power of the shares of the Fund on the Record Date, based on each dollar of net asset value of the Fund represented by such shares.

A quorum of the shareholders for the Fund is required in order to take any action with respect to each Proposal.

Votes cast by proxy or in person at the Meeting will be tabulated by the inspectors of election appointed for the Meeting. The inspectors of election will determine whether or not a quorum is present at the Meeting. The inspectors of election will treat abstentions as present for purposes of determining a quorum.

If you hold your shares directly (not through a broker-dealer, bank, insurance company or other intermediary), and if you return a signed proxy card that does not specify how you wish to vote on a Proposal, your shares will be voted "FOR" each Proposal.

Broker-dealer firms holding shares of the Fund in "street name" for the benefit of their customers and clients will request the instructions of such customers and clients on how to vote their shares on each Proposal before the Meeting. A broker-dealer that is a member of the New York Stock Exchange and that has not received instructions from a customer or client prior to the date specified in the broker-dealer firm's request for voting instructions may not vote such customer's or client's shares with respect to non-routine proposals. All of the proposals are non-routine proposals.

If you hold shares of the Fund through a broker-dealer, bank, insurance company or other intermediary (called a service agent) that has entered into a service agreement with the Fund or a distributor of the Fund, the service agent may be the record holder of your shares. At

4

the Meeting, a service agent will vote shares for which it receives instructions from its customers in accordance with those instructions. A signed proxy card or other authorization by a shareholder that does not specify how the shareholder's shares should be voted on a Proposal may be deemed to authorize a service provider to vote such shares in favor of the applicable Proposal. Depending on its policies, applicable law or contractual or other restrictions, a service agent may be permitted to vote shares with respect to which it has not received specific voting instructions from its customers. In those cases, the service agent may, but may not be required to, vote such shares in the same proportion as those shares for which the service agent has received voting instructions. Because of this practice, a small number of shareholders could determine how the Fund votes, if other shareholders fail to vote.

If you beneficially own shares that are held in "street name" through a broker-dealer or that are held of record by a service agent and you do not give specific voting instructions for your shares, they may not be voted at all or, as described above, they may be voted in a manner that you may not intend. In particular, failure to vote may not be an effective way to oppose these Proposals. Therefore, you are strongly encouraged to give your broker-dealer, service agent or participating insurance company specific instructions as to how you want your shares to be voted.

Franklin Templeton and its affiliates intend to vote Fund shares they own, whether as seed capital or otherwise, in favor of each Proposal. Unless otherwise provided in client guidelines, Franklin Templeton and its affiliates generally intend to vote Fund shares owned in a client account over which Franklin Templeton or an affiliate has discretionary authority in favor of each Proposal. If Franklin Templeton's ownership, or the ownership of a client account over which Franklin Templeton has discretionary authority, represents a sizeable enough portion of the Fund's outstanding shares, Franklin Templeton's vote will ensure that the Proposals for the Fund will be approved. Please see Appendix B for information regarding persons, including Franklin Templeton and its affiliates, that beneficially owned or owned of record 5% or more of the outstanding shares of a class of the Fund.

5

Each Proposal requires a "1940 Act Majority Vote" of the outstanding voting securities of the Fund, voting together as a single class. A "1940 Act Majority Vote" of the outstanding voting securities of the Fund means the affirmative vote of the lesser of (a) 67% or more of the voting power of the voting securities of the Fund that are present at the Meeting or represented by proxy if holders of shares representing more than 50% of the voting power of the outstanding voting securities of the Fund are present or represented by proxy or (b) more than 50% of the voting power of the outstanding voting securities of the Fund.

Approval of each Proposal for the Fund will occur only if a sufficient number of votes at the Meeting are cast "FOR" that Proposal.

Abstentions are not considered "votes cast" and, therefore, do not constitute a vote "FOR" Proposals. Any abstentions would effectively be treated as votes "AGAINST" all Proposals.

Please note that broker non-votes are not expected with respect to the matters to be voted on because brokers are required to receive instructions from the beneficial owners or persons entitled to vote in order to submit proxies on the Proposals. "Broker non-votes" are shares held by brokers or nominees, typically in "street name," as to which proxies have been returned but (a) instructions have not been received from the beneficial owners or persons entitled to vote and (b) the broker or nominee does not have discretionary voting power on a particular matter. Although not expected, if any broker non-votes are received, they would be treated the same as abstentions and would effectively be counted as votes "AGAINST" all Proposals.

Adjournments and Postponements

The Meeting may, by action of the chair of the Meeting and without any action by shareholders, be adjourned from time to time with respect to one or more matters to be considered at the Meeting, whether or not a quorum is present with respect to such matter. At the discretion of the chair, if a quorum is present with respect to a Proposal to be considered at the Meeting, a vote may be taken on the Proposal

6

prior to such adjournment. Such vote will be considered final regardless of whether the Meeting is adjourned with respect to any other Proposal. If the Meeting is postponed, the Fund will give notice of the postponement to shareholders. In the event of any inconsistency between this Proxy Statement and the Fund's governing documents or applicable law, the Fund's governing documents and applicable law will control.

PROPOSAL 1 - TO APPROVE A CHANGE IN THE FUND'S CLASSIFICATION FROM A "DIVERSIFIED" FUND TO A "NON-DIVERSIFIED" FUND

Introduction

You are being asked to approve a change in the Fund's classification from a "diversified" fund to a "non-diversified" fund. As discussed below, Franklin Templeton Fund Adviser, LLC ("FTFA"), the Fund's investment manager, and ClearBridge Investments, LLC ("ClearBridge"), the Fund's subadviser, believe that changing the Fund's classification to "non-diversified" will benefit the Fund by giving it greater flexibility to hold larger positions in certain companies, which will better allow the Fund to take more meaningful positions in securities in which ClearBridge has strong investment convictions and could better allow the Fund to meet its investment objective.

Changing the Fund's Classification from "Diversified" to "Non-Diversified"

The Investment Company Act of 1940, as amended (the "1940 Act") requires every mutual fund to be classified as either a "diversified" fund or "non-diversified" fund within the meaning of the 1940 Act. The 1940 Act also requires shareholders to approve a change in a fund's classification from a "diversified" fund to a "non-diversified" fund.

A "diversified" fund is limited as to the amount it may invest in any single issuer. Under the 1940 Act, a "diversified" fund may not, with respect to 75% of its total assets, invest in securities of any issuer if, as a result of such investment (i) more than 5% of the value of the fund's total assets would be invested in securities of any one issuer, or (ii) the fund would hold more than 10% of the outstanding voting securities of any one issuer. These percentage limitations do not apply to securities issued or guaranteed by the U.S. government, its agencies or instrumentalities, or to securities issued by other investment companies. With respect to the remaining 25% of its total assets, a "diversified" fund may invest more than 5% of its total assets in the

8

securities of one issuer. These limits apply at the time a "diversified" fund purchases a security; a "diversified" fund may exceed these limits if positions it already holds increase in value relative to the rest of the fund's holdings. In contrast, a "non-diversified" fund is not subject to the limits of a "diversified" fund; it may invest a greater percentage of its assets in a single issuer or a fewer number of issuers than a "diversified" fund.

The Fund currently is classified as a "diversified" fund. The Russell 1000 Growth Index (the "Index"), the Fund's performance benchmark, is becoming increasingly concentrated in a small number of large-cap technology companies. As of December 31, 2025, the five largest stocks by weight in the Index were: Nvidia (12.26%), Apple (10.51%), Microsoft (9.69%), Broadcom (4.84%) and Amazon (4.72%). The Fund is not currently permitted to invest in securities at a level reflecting the current market, as represented by the composition of the Index, without exceeding the limits permitted for a "diversified" fund.

Shareholders are being asked to approve a change in the Fund's classification from a "diversified" fund to a "non-diversified" fund, as defined under the 1940 Act. FTFA and ClearBridge believe that changing the Fund's classification to "non-diversified" will benefit the Fund by giving it greater flexibility to hold larger positions in certain companies. ClearBridge believes that this change will better allow the Fund to take more meaningful positions in securities in which ClearBridge has strong investment convictions and could better allow the Fund to meet its investment objective.

To the extent the Fund invests its assets in a smaller number of issuers, the Fund will be more susceptible to negative events affecting those issuers than a "diversified" fund. Investing a larger percentage of the Fund's assets in any one issuer could increase the Fund's risk of loss and its share price volatility because the value of its shares would be more susceptible to adverse events affecting that issuer. If the Fund takes a larger position in an issuer that subsequently has an adverse return, the Fund may have a greater loss than it would have had if ClearBridge had invested Fund assets in a larger number of issuers. ClearBridge will use this increased investment flexibility to take larger

9

positions in the securities of fewer issuers when it believes that doing so could benefit the Fund. If the Proposal is approved, trading costs to implement these changes to the Fund's portfolio (that is, to take larger positions in certain issuers) are estimated to be in the range of approximately $20,000. Such trading costs, which would principally reflect brokerage fees, would be borne by the Fund.

Except for maintaining a more focused portfolio, ClearBridge does not expect the proposed change in the classification of the Fund to substantially affect the manner in which the Fund's investment program is conducted at this time. Other than the change in the Fund's classification from "diversified" to "non-diversified," FTFA and ClearBridge do not propose or anticipate any material change in the management of the Fund if the Proposal is approved. Any future material changes to the management of the Fund will require consideration by the Board and disclosure in the Fund's prospectus or statement of additional information, as appropriate.

In addition, the Fund is (and will remain) subject to the diversification rules of the Internal Revenue Code of 1986, as amended (the "Tax Code"). These rules provide that, to maintain favorable tax treatment, the Fund must invest at least 50% of its total assets so that no more than 5% of its total assets is invested in the securities of any issuer, and so that it holds no more than 10% of the outstanding voting securities of any issuer. With respect to the remaining 50% of its total assets, the Fund is limited to investing 25% in the securities of a single issuer. These limits apply only as of the end of each quarter of the Fund's fiscal year, so the Fund may have a higher concentration in an issuer during periods between the ends of its fiscal quarters. However, ClearBridge has no current intention of investing in the securities of any single issuer beyond the Tax Code limits. Like the 1940 Act limits, the Tax Code limits do not apply to securities issued or guaranteed by the U.S. government, its agencies or instrumentalities, or to securities issued by other investment companies.

If shareholders of the Fund approve the Proposal, the change in the Fund's classification from "diversified" to "non-diversified" will become effective when the Fund's registration statement is revised or supplemented. If shareholders of the Fund do not approve the Proposal, the Fund will continue to operate as a "diversified" fund.

10

Board Evaluation

The Board unanimously approved changing the Fund's classification to a "non-diversified" fund and is recommending that shareholders approve changing the Fund's classification to a "non-diversified" fund at the Meeting. In determining to recommend that shareholders approve changing the Fund's classification to a "non-diversified" fund at the Meeting, the Board considered, among other factors, ClearBridge's statement that ClearBridge believes the Fund would benefit from changing its classification to a "non-diversified" fund because it would allow the Fund greater flexibility to hold larger positions in certain companies that ClearBridge recommends, and better allow the Fund to meet its investment objective. The Board considered that a fund that invests a larger percentage of its assets in a smaller number of issuers could be more susceptible to negative events affecting those issuers, and in that regard, considered ClearBridge's representation that it believes that the potential benefits of investing more of the Fund's assets in particular issuers justify the risks of following a "non-diversified" strategy. Additionally, the Board considered ClearBridge's representation that ClearBridge did not believe that the change would substantially affect the overall risk profile of the Fund.

Required Vote

To become effective, the change of the Fund's classification to a "non-diversified" fund must be approved by a "1940 Act Majority Vote" of the outstanding voting securities of the Fund, as such term is defined above in "Vote Required and Manner of Voting Proxies."

The Board unanimously recommends that you vote "FOR" Proposal 1.

11

PROPOSAL 2-TO AUTHORIZE THE FUND TO RELY ON THE MANAGER OF MANAGERS ORDER

Introduction

You are being asked to authorize the Fund's use of a "manager of managers" structure that would permit FTFA, the Fund's manager, or any other entity under common control with FTFA that serves as an adviser to the Fund (together, the "Manager"), subject to the approval of the Board of Trustees, to appoint subadvisers, and enter into, and materially amend, subadvisory agreements for the Fund without further shareholder approval. Currently, in order for the Manager to appoint a subadviser or materially modify a subadvisory agreement, the Fund must call and hold a shareholder meeting, create and distribute proxy materials, and solicit votes from its shareholders. This process is time-intensive, costly and slow. Without the delay inherent in holding shareholder meetings, the Fund would be able to act more quickly to appoint a subadviser when the Board of the Fund and the Manager believe that the appointment would benefit the Fund.

"Manager of Managers" Structure

Provisions of the 1940 Act require that shareholders of a mutual fund approve a subadvisory agreement with the subadviser and material amendments to an existing subadvisory agreement. The SEC, however, has issued an exemptive order (the "exemptive order") to the Manager and any existing or future registered open-end investment company advised by the Manager that permits the Manager to appoint and replace subadvisers for the Fund and to enter into and approve amendments to subadvisory agreements without first obtaining shareholder approval (the "Manager of Managers Structure").

The exemptive order allows the Manager to hire, without shareholder approval, new subadvisers that are affiliated with the Manager (e.g., the Manager and subadvisers are both indirectly wholly owned or partially owned by the same corporate parent, Franklin Resources), and new subadvisers that are not affiliated with the Manager in any way. However, the Board, including a majority of the Independent Trustees, must approve any new subadviser and any new

12

or amended subadvisory agreement for the Fund. In considering a new or existing subadvisory agreement, the Board is required to evaluate any material conflicts that may be present in a subadvisory arrangement. Before the Fund may rely on the exemptive order, the Fund's use of the Manager of Managers Structure must be approved by a "majority of the outstanding voting securities" of the Fund, as defined in the 1940 Act and discussed below.

Under the Manager of Managers Structure, the Manager would have the overall responsibility, subject to oversight by the Board, to oversee the Fund's subadvisers and recommend their hiring, termination and replacement. Specifically, the exemptive order requires the Manager to, subject to the review and approval of the Board, including a majority of the Independent Trustees: (a) set the Fund's overall investment strategy; (b) evaluate, select and recommend subadvisers to manage all or a portion of the Fund's assets; (c) allocate and, when appropriate, reallocate the Fund's assets among subadvisers; (d) monitor and evaluate the subadvisers' performance; and (e) implement procedures reasonably designed to ensure that each subadviser complies with the Fund's investment objective, policies and restrictions. Under the exemptive order, the Fund must disclose to its shareholders (i) the aggregate fees paid to the Manager and any subadvisers that are wholly-owned by the same corporate parent as the Manager (as noted above, the Fund's current manager and subadvisers are wholly-owned, indirectly, by Franklin Resources); and (ii) the aggregate fees paid to partially-owned and unaffiliated subadvisers. The replacement of the Manager or the imposition of material changes to the Fund's investment management agreement would, however, require prior shareholder approval. In addition, any new subadvisory agreement that directly or indirectly results in an increase in the aggregate advisory fee rate payable by the Fund would also require shareholder approval.

If the Manager, with the approval of the Board, including a majority of the Independent Trustees, determines that the use of the Manager of Managers Structure is in the best interests of the Fund, the Manager of Managers Structure would, without obtaining shareholder approval: (1) enable a new subadviser to commence providing services to the Fund more quickly and with less potential expense to the Fund;

13

(2) permit the Manager to allocate and reallocate the Fund's assets among itself and one or more subadvisers; and (3) permit the Board to approve material changes to a subadvisory agreement.

Under the Manager of Managers Structure, upon receiving approval of the Board, including a majority of the Independent Trustees, subadvisers selected by the Manager could immediately manage the Fund's assets. The Fund would, however, inform shareholders of the hiring of any new subadviser within 90 days after hiring the subadviser by providing shareholders with an information statement that contains substantially the same relevant information about the subadviser and the subadvisory agreement that the Fund would be required to send its shareholders in a proxy statement.

Approval of the Manager of Managers Structure will not affect any of the requirements under the federal securities laws that govern the Fund, the Manager, any proposed subadviser or any proposed subadvisory agreement with a subadviser, other than the requirement to have any future subadvisory agreement or amendment to the subadvisory agreement approved at a meeting of the Fund's shareholders. The Board, including the Independent Trustees, will continue to evaluate and approve all new subadvisory agreements with respect to the Fund between the Manager and any subadviser, as well as all changes to any subadvisory agreement.

Approval of this Proposal will not affect the Fund's fees. The Manager of Managers Structure will not at any time entail an increase in the investment management fees paid by the Fund. Further shareholder approval would be necessary to increase the investment management fees that are payable by the Fund, which is not contemplated. If the Fund implements the Manager of Managers Structure, the Manager, pursuant to its management agreement with the Fund, will continue, directly or through subadvisers, to provide the same level of management services to the Fund as it provides currently.

Please note that the Manager does not have any present intention to use the Manager of Managers Structure to appoint additional subadvisers for the Fund or replace the Fund's subadvisers.

14

If the shareholders of the Fund do not approve the use of a "manager of managers" structure, decisions regarding a proposed subadviser for that Fund or a material change to a subadvisory agreement with respect to that Fund will continue to require shareholder approval.

Board Evaluation

The Board, including a majority of the independent trustees, unanimously approved the Manager of Managers Structure and is recommending that shareholders approve the Manager of Managers Structure at the Meeting. In determining to recommend approval of the Proposal, the Board considered, among other factors, that the Manager of Managers Structure would enable the Fund to operate with greater efficiency in the future by allowing the Fund to use both affiliated (including those that are partially or wholly-owned by Frankin Resources) and unaffiliated subadvisers best suited to its needs without incurring potential delays and expense that could be associated with obtaining shareholder approvals. The Board also considered: (1) the Manager's continued responsibility, subject to Board oversight, to oversee the Fund's subadvisers; (2) the Manager's ability to operate in accordance with the conditions of the exemptive order; (3) that the Manager of Managers Structure would not change any fees paid to the Manager by the Fund or fees paid by Fund shareholders; and (4) that Board approval to appoint or replace future subadvisers would still be required

Required Vote

To become effective, the use of the Manager of Managers Structure must be approved by a "1940 Act Majority Vote" of the outstanding voting securities of that Fund, as such term is defined above in "Vote Required and Manner of Voting Proxies."

The Board recommends that you vote "FOR" Proposal 2.

The Fund does not hold annual meetings of shareholders. A shareholder proposal intended to be presented at a future special meeting of shareholders of the Fund must be received at the offices of the Fund, One Madison Avenue, 17^th Floor, New York, New York 10010, at a reasonable time before the Fund begins to print and mail its proxy materials. Timely submission of a proposal does not guarantee that such proposal will be included in a proxy statement.

Shareholder Communications

Shareholders who want to communicate with the Board or any individual Trustee should write to the Fund to the attention of the Secretary of the Fund (addressed to One Madison Avenue, 17^th Floor, New York, New York 10010). The letter should indicate that you are a Fund shareholder. If the communication is intended for a specific Trustee and so indicates it will be sent only to that Trustee. If a communication does not indicate a specific Trustee it will be sent to the chair of the nominating and governance committee and the outside counsel to the Independent Trustees for further distribution as deemed appropriate by such persons.

Additionally, shareholders with complaints or concerns regarding accounting matters may address letters to the Fund's Chief Compliance Officer ("CCO") at the offices of the Fund or at [email protected]. Shareholders who are uncomfortable submitting complaints to the CCO may address letters directly to the Chair of the Audit Committee of the Board that oversees the Fund. Such letters may be submitted on an anonymous basis.

Expense of Proxy Solicitation

The cost of preparing, printing and mailing the enclosed proxy, accompanying notice and the Proxy Statement and all other costs in connection with the solicitation of proxies will be borne by the Fund. Solicitation may be made by letter or telephone by officers or employees of FTFA or its affiliates, or by dealers and their representatives. Brokerage houses, banks and other fiduciaries may be requested to forward proxy solicitation material to their principals to obtain authorization for the execution of proxies. FTFA or an affiliate will reimburse brokerage firms, custodians, banks and fiduciaries for their expenses in forwarding the Proxy Statement and proxy materials to the beneficial owners of the Fund's shares. In addition, FTFA, on behalf of the Fund, has retained EQ Fund Solutions, LLC, 28 Liberty Street, 53^rd Floor, New York, NY 10005, a proxy solicitation firm, to assist in the solicitation of proxies.
