Dear Shareholder:

Recently, Janus Capital Group Inc. (“Janus”), the parent company of Janus Capital Management LLC (“Janus Capital”), your fund’s investment adviser, and Henderson Group plc (“Henderson”) entered into an Agreement and Plan of Merger pursuant to which Janus and Henderson have agreed to effect an all-stock merger of equals strategic combination of their respective businesses, with Janus Capital surviving the merger as a direct wholly-owned subsidiary of Henderson (the “Transaction”). Subject to certain conditions, the Transaction is currently expected to close during the second quarter of 2017. The closing may be deemed to cause an “assignment” of the current advisory agreements between Janus Capital and the Janus mutual funds, and any sub-advisory agreements entered into by Janus Capital, which would cause such agreements to terminate.

In order to provide continuity of advisory services for your fund after the closing of the Transaction, the Board of Trustees for your fund is requesting that you vote on proposals (i) to approve a new investment advisory agreement between Janus Capital and your fund to permit Janus Capital to continue to serve as investment adviser to the fund following the Transaction; and (ii) to the extent applicable to your fund, to approve a new investment sub-advisory agreement between Janus Capital and your fund’s current sub-adviser to permit such sub-adviser to continue to manage the fund following the Transaction.

In addition, for Janus Asia Equity Fund and Janus Global Real Estate Fund, the Board of Trustees is requesting that you vote on a proposal to approve a new sub-advisory agreement between Janus Capital and Henderson Investment Management Limited, a subsidiary of Henderson, to become effective upon the closing of the Transaction.

The Board of Trustees is also requesting that you vote on a proposal to elect an additional trustee to serve on the Board of Trustees, to take effect upon the closing of the Transaction.

Finally, the Board of Trustees is also requesting that you vote on a proposal to authorize Janus Capital to enter into and materially amend sub-advisory agreements in the future with wholly-owned sub-advisers and unaffiliated sub-advisers, with the approval of the Board of Trustees, but without obtaining additional shareholder approval. This proposal is presented for approval by those funds that do not already provide this flexibility to Janus Capital.

The proposals will be presented to shareholders at a joint Special Meeting of Shareholders to be held on April 6, 2017. The proposals are briefly summarized in the synopsis that precedes the enclosed joint proxy statement (the “Proxy Statement”). The Proxy Statement includes a detailed discussion of the proposals, which you should read carefully.

The Board of Trustees unanimously recommends that shareholders vote FOR the proposal(s) applicable to their fund.

You can vote in one of four ways:

Your vote is important, so please read the enclosed Proxy Statement carefully and submit your vote. If you have any questions about the proposals, please call the proxy solicitor, Computershare Fund Services, at 1-866-492-0863.

Thank you for your consideration of the proposals. We value you as a shareholder and look forward to our continued relationship.

Sincerely,

Bruce L. Koepfgen

President and Chief Executive Officer

of Janus Investment Fund

SYNOPSIS

The following synopsis is a brief overview of the matters to be voted on at the joint Special Meeting of the Shareholders of the Janus funds listed in the enclosed joint proxy statement (“Proxy Statement”), or at any adjournment or postponement thereof (the “Meeting”). This synopsis is qualified in its entirety by the remainder of this Proxy Statement. The Proxy Statement contains more detailed information about each proposal, and we encourage you to read it in its entirety before voting.

Completion of the Transaction is subject to the satisfaction or waiver of certain conditions, including the receipt of certain third party consents, including approval of new investment advisory agreements by shareholders of Janus Capital-advised U.S. registered investment companies, including the Funds, representing at least 67.5% of the aggregate assets under management of the Janus Capital-advised U.S. registered investment companies. Janus and Henderson currently expect to complete the Transaction during the second quarter of 2017.

Shareholders of the Janus funds listed in the enclosed Proxy Statement (each a “Fund” and, collectively, the “Funds”) are not being asked to vote on the Transaction. Rather, shareholders of the Funds are being asked to vote on one or more proposals that are being presented to them as a result of the Transaction.

The Closing may be deemed to cause an “assignment” of each Fund’s current investment advisory agreement with Janus Capital, which would cause such agreement to terminate. Similarly, for those Funds with a sub-advisory agreement with INTECH Investment Management LLC (“INTECH”), Perkins Investment Management LLC (“Perkins”) or Janus Capital Singapore Pte. Limited (“Janus Singapore”), the Closing may be deemed to cause an “assignment” of each such Fund’s existing sub-advisory agreement, which would cause such agreement to terminate. Janus Capital recommended, and the Board of Trustees (the “Board,” the “Board of Trustees,” or the “Trustees”) of Janus Investment Fund (the “Trust”) has approved, and recommends that shareholders of each Fund approve, a new investment advisory agreement between their Fund and Janus Capital, and a new sub-advisory agreement between Janus Capital and INTECH, Perkins, or Janus Singapore, as applicable, in order for Janus Capital and each current sub-adviser to continue to provide advisory services to each Fund following the Transaction. Each of these proposed agreements will have substantially similar terms as the corresponding current agreement.

Contingent upon the closing of the Transaction, shareholders of Janus Asia Equity Fund are being asked to approve a sub-advisory agreement between Janus Capital and Henderson Investment Management Limited (“HIML”), a subsidiary of Henderson. If approved, HIML would replace Janus Singapore as sub-adviser to Janus Asia Equity Fund following the Closing of the Transaction. If the Closing does not occur, Janus Singapore would continue to serve as sub-adviser to Janus Asia Equity Fund.

Contingent upon the closing of the Transaction, shareholders of Janus Global Real Estate Fund are being asked to approve a sub-advisory agreement between Janus Capital and HIML. If approved, HIML would become the sub-adviser to Janus

i

Table of Contents

Global Real Estate Fund and would be responsible for the day-to-day management of a portion of the investment portfolio of Janus Global Real Estate Fund following the Closing of the Transaction, subject to the oversight of Janus Capital. Janus Capital would continue to be responsible for the day-to-day management of the remaining portion of the investment operations of Janus Global Real Estate Fund. If the Closing does not occur, Janus Capital would continue to manage the entire portfolio of Janus Global Real Estate Fund.

The Board of Trustees is requesting that shareholders elect an additional Trustee, Diane L. Wallace (the “Trustee Nominee”).

Shareholders are also being asked to consider a proposal to implement a “manager-of-managers” structure in order to provide Janus Capital with greater flexibility with respect to the appointment of sub-advisers in the future.

Each of these proposals is discussed further below. Not all of these proposals impact all Funds. Please refer to the table at the end of this synopsis as a reference for which proposal(s) applies to you.

Proposals 1, 2 and 3: Approve New Investment Advisory and Sub-advisory Agreements

ii

Table of Contents

The Adviser has determined that it would be in the best interest of Janus Global Real Estate Fund to draw upon the resources of Janus Henderson following the closing of the Transaction. The Adviser recommended, and the Board of Trustees approved, a sub-advisory agreement with HIML with respect to Janus Global Real Estate Fund, to take effect upon the Closing of the Transaction. HIML would be responsible for the day-to-day management of a portion of the investment portfolio of Janus Global Real Estate Fund subject to the general oversight of Janus Capital. Janus Capital would continue to be responsible for the day-to-day management of the remaining portion of the investment portfolio of Janus Global Real Estate Fund. Guy Barnard, Co-Head of HIML’s Global Property Equities Team, Tim Gibson, Co-Head of HIML’s Global Property Equities Team, and Patrick Brophy, Portfolio Manager of Janus Global Real Estate Fund for Janus Capital, would serve as portfolio managers of Janus Global Real Estate Fund. HIML is an SEC registered investment adviser and is an indirect, wholly-owned subsidiary of Henderson and serves as investment sub-adviser to several mutual funds offered by Henderson. No changes to the investment objective, policies or restrictions of Janus Global Real Estate Fund are anticipated in connection with the appointment of HIML as sub-adviser. The sub-advisory agreement with HIML will not take effect if the Closing does not occur. In that case, Janus Capital would continue to manage the entire portfolio of Janus Global Real Estate Fund as adviser.

HIML is an SEC registered investment adviser and is an indirect, wholly-owned subsidiary of Henderson. As a global money manager, HIML and its affiliates (“Henderson Global Investors”) provide a full spectrum of investment products and services to institutions and individuals around the world. Henderson Global Investors has been managing assets for clients since 1934. Henderson Global Investors is a multi-skill, multi-asset management business with a worldwide distribution network. The business address of HIML is 201 Bishopsgate, London UK EC2M 3AE.

Proposal 4: Election of an Additional Trustee

Each current Trustee and the Trustee Nominee is an Independent Trustee, meaning that each is not an “interested person” (as defined in Section 2(a)(19) of the Investment Company Act of 1940, as amended (the “1940 Act”)) of the Trust, Janus Capital, any sub-adviser, or Henderson. Information about the Trustee Nominee, including age, principal occupations during the past five years, and other information, such as the Trustee Nominee’s experience, qualifications, attributes, or skills, is set forth in this Proxy Statement.

Proposal 5: Approval of Manager of Managers Structure

Voting

Whichever method you choose, please take the time to read the full text of the Proxy Statement before you vote.

It is important that shareholders respond to ensure that there is a quorum for the Meeting. If we do not receive your response within a few weeks, you may be contacted by Computershare Fund Services (“Computershare”), the proxy solicitor engaged by Janus Capital, who will remind you to vote your shares and help you return your proxy.

iv

Table of Contents

Shareholders of each applicable Fund (with all classes of shares of a Fund voting together as a single class) will vote separately on Proposals 1, 2, 3 and 5 relating to their Fund. An unfavorable vote on any proposal by the shareholders of one Fund will not affect the implementation of such proposal by another Fund if the proposal is approved by the shareholders of that Fund. However, Proposals 1, 2 and 3 will only take effect upon the closing of the Transaction, which is conditioned upon obtaining the approval of new investment advisory agreements by shareholders of Janus funds representing a specified percentage of assets under management.

For Proposal 4, the Trustee election will be determined by the affirmative vote of a plurality (the greatest number of affirmative votes) of the shares of all funds of the Trust, including all Funds listed in this Proxy Statement and certain funds of the Trust for which votes are being solicited pursuant to separate proxy statements. Proposal 4 will only take effect upon the closing of the Transaction.

A quorum of shareholders is required to take action at the Meeting. The presence in person or by proxy of the holders of record of 30% of shares outstanding and entitled to vote at the Meeting constitutes a quorum.

INTRODUCTION

The Adviser is a direct subsidiary of Janus Capital Group Inc. (“Janus”), a publicly traded company with principal operations in financial asset management businesses and approximately $198.9 billion in assets under management as of September 30, 2016. Recently, Janus and Henderson Group plc (“Henderson”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) pursuant to which Janus and Henderson have agreed to effect an all-stock merger of equals strategic combination of their respective businesses, with Janus surviving the merger as a direct wholly-owned subsidiary of Henderson (the “Transaction”). Henderson is an independent global asset management business founded in 1934 with approximately $131.2 billion in assets under management, as of September 30, 2016.

The Transaction will be effected via a share exchange with each share of Janus common stock exchanged for 4.7190 newly issued ordinary shares in Henderson. Based on the current number of shares outstanding, upon closing of the Transaction, Henderson and Janus shareholders are expected to own approximately 57% and 43%, respectively, of the ordinary shares of the combined company, which will be renamed Janus Henderson Global Investors plc (“Janus Henderson”). Janus Henderson will have approximately $326 billion in assets under management and a combined market capitalization of $5.75 billion. The name of your Fund, and most of the mutual funds offered by the Adviser, will also be renamed to reflect “Janus Henderson” in the name. Janus expects that the combination of these two complementary businesses will create a leading global active asset manager with significant scale, diverse products and investment strategies, and depth and breadth in global distribution, resulting in an organization that will be well-positioned to provide world-class client service.

Under the terms of the Merger Agreement, as of the effective time of the Transaction, (i) Richard M. Weil, the current Chief Executive Officer of Janus, will become a co-Chief Executive Officer of Janus Henderson and (ii) Andrew J. Formica, the current Chief Executive Officer of Henderson, will become a co-Chief Executive Officer of Janus Henderson.

Janus Henderson will have a Board of Directors consisting initially of twelve directors, (i) six of whom will be persons designated by the existing Board of Directors of Henderson, and (ii) six of whom will be persons designated by the existing Board of Directors of Janus.

Completion of the Transaction is subject to the satisfaction or waiver of certain conditions, including (i) the requisite approval of the Merger Agreement by the holders of common stock of Janus; (ii) the requisite approval of the shareholders of Henderson of the Transaction and certain related matters; (iii) regulatory approvals; and (iv) receipt of certain third party consents, including approval of new investment advisory agreements by shareholders of Janus Capital-advised U.S. registered investment companies, including the Funds, representing at least 67.5% of the aggregate assets under management of the Janus Capital-advised U.S. registered investment companies.

The Merger Agreement contains certain termination rights for each of Henderson and Janus, including in the event that (i) the Transaction is not consummated on or before September 30, 2017, (ii) the approval of the Transaction by the shareholders of Henderson or the stockholders of Janus is not obtained at the respective shareholder meetings or (iii) if any restraint that prevents, makes illegal or prohibits the consummation of the Transaction shall have become final and non-appealable. In addition, Henderson and Janus can each terminate the Merger Agreement prior to the shareholder meeting of the other party if, among other things, the other party’s board of directors has changed its recommendation that its shareholders approve the Transaction, and adopt the Merger Agreement.

Janus and Henderson currently expect to complete the Transaction during the second quarter of 2017.

Shareholders of the Funds are being asked to consider Proposals 1-3 (approval of advisory and sub-advisory agreements) and 4 (appointment of trustee) in connection with the Transaction. These Proposals are contingent upon the Closing of the Transaction and will take effect only if the Transaction closes. Proposal 5 (manager of managers proposal) is not related to the Transaction and will take effect whether or not the Transaction closes.

PROPOSAL 1

APPROVAL OF NEW INVESTMENT ADVISORY AGREEMENT

(All Funds)

Background

Pursuant to a separate investment advisory agreement between Janus Capital and the Trust on behalf of each Fund (each a “Current Advisory Agreement” and collectively, the “Current Advisory Agreements”), Janus Capital serves as each Fund’s investment adviser. The date of each Fund’s Current Advisory Agreement and the date on which it was last approved by shareholders and approved for continuance by the Board are provided in Appendix B to this Proxy Statement.

Each Current Advisory Agreement, as required by Section 15 of the Investment Company Act of 1940, as amended (the “1940 Act”), provides for its automatic termination in the event of its “assignment” (as defined in the 1940 Act). The consummation of the Transaction may be deemed an “assignment” of each Current Advisory Agreement which would cause the automatic termination of each Current Advisory Agreement, as required by the 1940 Act. The 1940 Act requires that a new advisory agreement be approved by the board of trustees and the shareholders of a fund in order for it to become effective.

The Proposal

With respect to each Fund, shareholders of the Fund are being asked to approve a new investment advisory agreement between the Trust, on behalf of the Fund, and the Adviser that are substantially similar to the Current Advisory Agreement to take effect immediately after the Transaction or shareholder approval, whichever is later (each, a “New Advisory Agreement” and collectively, the “New Advisory Agreements”).

At an in-person meeting of the Board on December 8, 2016, and for the reasons discussed below (see “Board Considerations” after Proposal 3 in this Proxy Statement), the Board, all of whom are Trustees who are not “interested persons” (as defined in Section 2(a)(19) of the 1940 Act) of the Funds, the Adviser, any sub-adviser or Henderson (the “Independent Trustees”), unanimously approved the New Advisory Agreement on behalf of each Fund and unanimously recommended approval of the New Advisory Agreement by shareholders. For additional information regarding the Board’s consideration of the New Advisory Agreements, see “Board Considerations” after Proposal 3 in this Proxy Statement. The form of the New Advisory Agreement is attached hereto as Appendix N to this Proxy Statement.

Comparison of Current Advisory Agreements and New Advisory Agreements

The terms of each New Advisory Agreement are substantially similar to those of the Current Advisory Agreement. There is no change in the fee rate payable by each Fund to the Adviser. Changes made to the New Advisory Agreement compared to the Current Advisory Agreement include the date of expiration, and, for Funds with a performance-based investment advisory fee, changes to ensure continuity of the advisory fee based on the Fund’s historical performance, as provided for under the Current Advisory Agreement. If approved by shareholders of a Fund, the New Advisory Agreement for each Fund will have an initial term until February 1, 2018 and will continue in effect from year to year if such continuance is approved at least annually in the manner required by the 1940 Act and the rules and regulations thereunder. Below is a comparison of certain terms of the Current Advisory Agreement to the terms of the New Advisory Agreement.

Investment Advisory Services. The investment advisory services to be provided by the Adviser to each Fund are the same under the Current Advisory Agreements and the New Advisory Agreements. Both the Current Advisory Agreements and New Advisory Agreements provide that the Adviser shall furnish continuous advice and recommendations to each Fund, and shall have authority to act with respect thereto, as to the acquisition, holding, or disposition of any or all of the securities or other assets which each Fund may own or contemplate acquiring from time to time. The Adviser shall give due consideration to the investment policies and restrictions and the other statements concerning each Fund in the Trust’s Amended and Restated Declaration of Trust, as then in effect, the Trust’s Amended and Restated Bylaws, as then in effect, and the registration statements of the Trust, and to provisions of the Internal Revenue Code, as applicable to each Fund as a regulated investment company. In addition, the Adviser shall cause its officers to attend meetings and furnish oral and written reports, as each Fund may reasonably require, in order to keep the Board and appropriate officers of each Fund and the Trust fully informed as to the condition of the investment portfolio of each Fund. The investment advisory services are expected to be provided by the same personnel of the Adviser under the New Advisory Agreements as under the Current Advisory Agreements.

Janus Global Unconstrained Bond Fund and Janus Diversified Alternatives Fund each have a subsidiary to which Janus Capital provides investment advisory services (each a “Subsidiary”). Each Subsidiary has entered into a separate investment

Table of Contents

advisory agreement with Janus Capital (each a “Subsidiary Advisory Agreement”). The consummation of the Transaction may be deemed an “assignment” of each Subsidiary Advisory Agreement, which would cause the automatic termination of each Subsidiary Advisory Agreement, as required by the 1940 Act. In order to permit Janus Capital to continue to serve as investment adviser to each Subsidiary following the Transaction, if the New Advisory Agreement is approved, Janus Capital will enter into a new investment advisory agreement with each Subsidiary, which will be substantially similar to the current Subsidiary Advisory Agreement.

Fees. Under each Current Advisory Agreement and New Advisory Agreement, the Fund pays to the Adviser an investment advisory fee which is calculated daily and paid monthly. Each Fund’s investment advisory fee rate under the New Advisory Agreement for such Fund is identical to the investment advisory fee rate under the Current Advisory Agreement. Certain Funds pay an investment advisory fee rate that may adjust up or down based on such Fund’s performance relative to the cumulative investment record of its benchmark index over a performance measurement period. For each such Fund, the terms of such performance adjustment under the New Advisory Agreement are identical to the terms of such performance adjustment under the Current Advisory Agreement. Appendix C to this Proxy Statement sets forth the investment advisory fee rate applicable to each Fund. Appendix G to this Proxy Statement sets forth the amount of fees paid to the Adviser during each Fund’s most recently ended fiscal year.

Payment of Expenses. Under each Current Advisory Agreement and the New Advisory Agreement, the Funds assume and pay all expenses incidental to their organization, operations and business not specifically assumed or agreed to be paid by the Adviser. These Fund expenses include custodian and transfer agency fees and expenses, brokerage commissions and dealer spreads, and other expenses in connection with the execution of portfolio transactions, legal and accounting expenses, interest, taxes, a portion of trade association or other investment company organization dues and expenses, registration fees, expenses of shareholders’ meetings, reports to shareholders, fees and expenses of Independent Trustees, and other costs of complying with applicable laws regulating the sales of Fund shares. The Funds, along with other Janus funds, also pay some or all of the salaries, fees, and expenses of certain Fund officers and employees of the Adviser (also sharing certain expenses and salaries for the Funds’ Chief Compliance Officer and other compliance-related personnel employed by the Adviser as authorized by the Trustees from time to time). For Janus Money Market Fund and Janus Government Money Market Fund, the Adviser pays for certain of these expenses pursuant to an Administration Agreement between the Adviser and these Funds.

Other Services. Under each Current Advisory Agreement and New Advisory Agreement, the Adviser is authorized, but not obligated, to perform management and administrative services necessary for the operation of each Fund. Specifically, the Adviser is authorized to conduct relations with custodians, depositories, transfer and pricing agents, accountants, attorneys, underwriters, brokers and dealers, corporate fiduciaries, insurance company separate accounts, insurers, banks and such other persons in any such other capacity deemed by the Adviser to be necessary or desirable. The Adviser shall also generally monitor and report to the officers of the Trust regarding each Fund’s compliance with investment policies and restrictions as set forth in the currently effective prospectus and statement of additional information relating to the shares of each Fund. Additionally, the Adviser shall make reports to the Board of its performance of services upon request and furnish advice and recommendations with respect to such other aspects of the business and affairs of each Fund as it shall determine to be desirable. The Adviser is also authorized, subject to review by the Board, to furnish such other services as the Adviser shall from time to time determine to be necessary or useful to perform the services contemplated by the agreement. The Adviser also serves as administrator to the Funds pursuant to an Administration Agreement between Janus Capital and the Trust. See “Affiliated Service Providers, Affiliated Brokerage and Other Fees—Administrator” for additional information regarding these administrative services.

Limitation on Liability. The Current Advisory Agreements and New Advisory Agreements provide that the Adviser will not be liable for any error of judgment or mistake of law or for any loss arising out of any investment or for any act or omission taken with respect to a Fund, except for willful misfeasance, bad faith or gross negligence in the performance of its duties, or by reason of reckless disregard of its obligations and duties and except to the extent otherwise provided by law.

Continuance. The Current Advisory Agreement for each Fund continues in effect for successive one-year periods after its initial term, if such continuance is specifically approved at least annually by (a) the vote of a majority of the Independent Trustees cast in person at a meeting called for the purpose of voting on the terms of such renewal, and (b) either the Trustees of the Trust or the affirmative vote of a majority of the outstanding voting securities of the Fund. The New Advisory Agreement for each Fund will have an initial term until February 1, 2018, and will continue thereafter for successive one-year periods if approved annually in the same manner required under the Current Advisory Agreement.

Termination. The Current Advisory Agreement and New Advisory Agreement for each Fund provide that the agreement may be terminated at any time, without penalty, by the Board, or by the shareholders of the Fund acting by vote of at least a

5

Table of Contents

majority of its outstanding voting securities, provided in either case that sixty (60) days’ advance written notice of termination be given to the Adviser at its principal place of business. Further, the Current Advisory Agreement and the New Advisory Agreement may be terminated by the Adviser at any time, without penalty, by giving sixty (60) days’ advance written notice of termination to the Fund, addressed to its principal place of business.

Interim Advisory Agreements

In the event shareholders of a Fund do not approve the New Advisory Agreement at the Meeting prior to the closing of the Transaction, an interim investment advisory agreement between the Adviser and such Fund (each, an “Interim Advisory Agreement” and collectively, the “Interim Advisory Agreements”) will take effect upon the closing of the Transaction. At the December 8, 2016 meeting, the Board, all of whom are Independent Trustees, unanimously approved an Interim Advisory Agreement for each Fund in order to assure continuity of investment advisory services to the Funds after the Transaction. The terms of each Interim Advisory Agreement are substantially identical to those of the applicable Current Advisory Agreement and New Advisory Agreement, except for the term and escrow provisions described below. The Interim Advisory Agreement will continue in effect for a term ending on the earlier of 150 days from the closing of the Transaction (the “150-day period”) or when shareholders of the Fund approve the New Advisory Agreement. Pursuant to Rule 15a-4 under the 1940 Act, compensation earned by the Adviser under an Interim Advisory Agreement will be held in an interest-bearing escrow account. If shareholders of a Fund approve the New Advisory Agreement prior to the end of the 150-day period, the amount held in the escrow account under the Interim Advisory Agreement will be paid to the Adviser. If shareholders of a Fund do not approve the New Advisory Agreement prior to the end of the 150-day period, the Board will take such action as it deems to be in the best interests of the Fund, and the Adviser will be paid the lesser of its costs incurred in performing its services under the Interim Advisory Agreement or the total amount in the escrow account, plus interest earned.

Other Actions Contemplated in Connection with the Transaction

Fund mergers involving certain Funds are proposed to occur at or about the time of the closing of the Transaction:

Janus Forty Fund. The Board has approved a merger of Janus Twenty Fund, a series of the Trust, into Janus Forty Fund. The merger is contingent on approval by shareholders of Janus Twenty Fund, which will be solicited pursuant to a separate proxy statement/prospectus that will contain information about the proposed merger and will be sent separately to Janus Twenty Fund shareholders. The merger does not require approval of shareholders of Janus Forty Fund and shareholders of Janus Forty Fund are not being asked to vote on the merger. The merger will not result in any changes to Janus Forty Fund’s investment strategies, policies, management or contractual advisory fee rates.

The merger is contingent on approval by shareholders of Janus Fund, which will be solicited pursuant to a separate proxy statement/prospectus that will contain information about the proposed merger and will be sent separately to Janus Fund shareholders. The merger does not require approval of shareholders of Janus Research Fund and shareholders of Janus Research Fund are not being asked to vote on the merger. The merger will not result in any changes to Janus Research Fund’s investment strategies, policies, management or contractual advisory fee rates.

INTECH U.S. Managed Volatility Fund. The Board has approved a merger of INTECH U.S. Core Fund into INTECH U.S. Managed Volatility Fund. The merger is contingent on approval by shareholders of INTECH U.S. Core Fund, which will be solicited pursuant to a separate proxy statement/prospectus that will contain information about the proposed merger and will be sent separately to INTECH U.S. Core Fund shareholders. The merger does not require approval of shareholders of INTECH U.S. Managed Volatility Fund and shareholders of INTECH U.S. Managed Volatility Fund are not being asked to vote on the merger.

The merger does not require approval by shareholders of Janus Global Technology Fund and shareholders of Janus Global Technology Fund are not being asked to vote on the merger.

Certain Conditions under the 1940 Act

The Board has been advised that the parties to the Merger Agreement have structured the Transaction in reliance upon Section 15(f) of the 1940 Act. Section 15(f) provides in substance that when a sale of a controlling interest in an investment adviser occurs, the investment adviser or any of its affiliated persons may receive any amount or benefit in connection with the sale so long as two conditions are satisfied. The first condition of Section 15(f) is that, during the three-year period following the consummation of a transaction, at least 75% of the investment company’s board of directors must not be “interested persons” (as defined in the 1940 Act) of the investment adviser or predecessor adviser. The composition of the Board of the Trust currently meets this test and would continue to meet this test after the election of an additional trustee pursuant to Proposal 4. Second, an “unfair burden” (as defined in the 1940 Act, including any interpretations or no-action letters of the Securities and Exchange Commission (the “SEC”) or the staff of the SEC) must not be imposed on the investment company as a result of the transaction relating to the sale of such interest, or any express or implied terms, conditions or understandings applicable thereto. The term “unfair burden” (as defined in the 1940 Act) includes any arrangement, during the two-year period after the transaction, whereby the investment adviser (or predecessor or successor adviser), or any “interested person” (as defined in the 1940 Act) of such an adviser, receives or is entitled to receive any compensation, directly or indirectly, from the investment company or its security holders (other than fees for bona fide investment advisory or other services) or from any person in connection with the purchase or sale of securities or other property to, from or on behalf of the investment company (other than bona fide ordinary compensation as principal underwriter for the investment company). Under the Merger Agreement, Henderson has acknowledged Janus’s reliance upon the benefits and protections provided by Section 15(f) and has agreed not to take, and to cause its affiliates not to take, any action that would have the effect, directly or indirectly, of causing the requirements of any of the provisions of Section 15(f) not to be met in respect of the Transaction.

Payments to Affiliates. During each Fund’s last fiscal year, no Fund made any material payments to the Adviser or Sub-Adviser to such Fund or any affiliated person of the Adviser or Sub-Adviser to such Fund for services provided to the Fund (other than pursuant to the Current Advisory Agreement, Current Sub-Advisory Agreement, Administration Agreement, or fees paid to the Distributor or Janus Services as described herein).

Shareholder Approval

For purposes of determining the approval of the New Advisory Agreement, abstentions and broker non-votes will have the same effect as shares voted against the proposal.

An unfavorable vote on the proposal to approve the New Advisory Agreement by the shareholders of one Fund will not affect the implementation of the proposal by another Fund if the proposal is approved by the shareholders of that Fund. However, the New Advisory Agreement will only take effect upon the closing of the Transaction, which is conditioned upon obtaining the approval of new advisory agreements by shareholders of Janus funds representing a specified percentage of assets under management.

In the event that the Transaction does not, for any reason, occur, each Current Advisory Agreement will continue in effect in accordance with its terms.

The Board unanimously recommends that shareholders of each Fund vote FOR approval of the Fund’s New Advisory Agreement.

PROPOSAL 2

APPROVAL OF NEW INVESTMENT SUB-ADVISORY AGREEMENT WITH CURRENT SUB-ADVISER

(Sub-Advised Funds)

Background

For certain Funds, the Adviser has retained either a direct wholly-owned subsidiary, or an indirect wholly-owned subsidiary of Janus as sub-adviser to manage the assets of the Fund.

The Adviser has entered into (i) a separate investment sub-advisory agreement with INTECH with respect to each INTECH Fund (each a “Current INTECH Sub-Advisory Agreement”), (ii) a separate investment sub-advisory agreement with Perkins with respect to each Perkins Fund (each a “Current Perkins Sub-Advisory Agreement”), and (iii) an investment sub-advisory agreement with Janus Singapore with respect to Janus Asia Equity Fund (the “Current Janus Singapore Sub-Advisory Agreement”). Collectively, the Current INTECH Sub-Advisory Agreements, the Current Perkins Sub-Advisory Agreements and the Current Janus Singapore Sub-Advisory Agreement are referred to herein as the “Current Sub-Advisory Agreements” and each as a “Current Sub-Advisory Agreement.” The date of each Current Sub-Advisory Agreement and the date it was last approved by shareholders and approved for continuance by the Board are provided in Appendix D to this Proxy Statement.

As with the Current Advisory Agreements, each Current Sub-Advisory Agreement, as required by Section 15 of the 1940 Act, provides for its automatic termination in the event of its assignment. Each of INTECH, Perkins and Janus Singapore, is either a direct wholly-owned subsidiary of the Adviser or an indirect wholly-owned subsidiary of Janus. Therefore, the consummation of the Transaction may be deemed an “assignment” of each Current Sub-Advisory Agreement. In addition, each Current Sub-Advisory Agreement provides that it will terminate upon the termination of the Current Advisory Agreement with respect to such Fund. As a result, the consummation of the Transaction would result in the termination of each Current Sub-Advisory Agreement.

The 1940 Act requires that a new sub-advisory agreement be approved by shareholders in order for it to become effective.

The Proposal

Shareholders of each INTECH Fund are being asked to approve a new sub-advisory agreement between the Adviser and INTECH (each a “New INTECH Sub-Advisory Agreement”). Shareholders of each Perkins Fund are being asked to approve a new sub-advisory agreement between the Adviser and Perkins (each a “New Perkins Sub- Advisory Agreement”). Shareholders of Janus Asia Equity Fund are being asked to approve a new sub-advisory agreement between the Adviser and Janus Singapore (the “New Janus Singapore Sub-Advisory Agreement” and, together with the New INTECH Sub-Advisory Agreements and New Perkins Sub-Advisory Agreements, each a “New Sub-Advisory Agreement” and collectively, the “New Sub-Advisory Agreements”). Each New Sub-Advisory Agreement will be substantially similar to the Current Sub-Advisory Agreement for each Fund.

Table of Contents

At the December 8, 2016 Board meeting, and for the reasons discussed below (see “Board Considerations” after Proposal 3 in this Proxy Statement), the Board, all of whom are Independent Trustees, unanimously approved the New Sub-Advisory Agreement on behalf of each applicable Fund and unanimously recommended approval of the New Sub-Advisory Agreement by shareholders. For additional information regarding the Board’s consideration of the New Sub-Advisory Agreements, see “Board Considerations” after Proposal 3 in this Proxy Statement. The form of the New INTECH Sub-Advisory Agreement is attached hereto as Appendix O to this Proxy Statement. The form of the New Perkins Sub-Advisory Agreement is attached hereto as Appendix P to this Proxy Statement. The form of the New Janus Singapore Sub-Advisory Agreement is attached hereto as Appendix Q to this Proxy Statement.

Because each New Sub-Advisory Agreement, like each Current Sub-Advisory Agreement, is between the Adviser and the Sub-Adviser, a Fund’s New Sub-Advisory Agreement will not take effect until the New Advisory Agreement for such Fund has been approved by shareholders. For Janus Asia Equity Fund, the New Sub-Advisory Agreement will not take effect if a separate proposal to appoint a new sub-adviser is approved by shareholders. See Proposal 3, beginning at page 14.

Comparison of Current Sub-Advisory Agreements and New Sub-Advisory Agreements

The terms of each New Sub-Advisory Agreement are substantially similar to those of the corresponding Current Sub-Advisory Agreement. There is no change in the fee rate payable by the Adviser to the Sub-Adviser. If approved by shareholders of a Fund, the New Sub-Advisory Agreement for the Fund will have an initial term through February 1, 2018 and will continue in effect from year to year thereafter if such continuance is approved for the Fund at least annually in the manner required by the 1940 Act and the rules and regulations thereunder. Below is a comparison of certain terms of the Current Sub-Advisory Agreements to the terms of the New Sub-Advisory Agreements.

Sub-Advisory Services. Under the terms of the agreements, the sub-advisory services provided by the Sub-Adviser to each Fund under the New Sub-Advisory Agreements and to be provided under the Current Sub-Advisory Agreements are the same. Both the Current Sub-Advisory Agreements and New Sub-Advisory Agreements provide that the Sub-Adviser shall manage the investment operation of the Fund and the composition of its investment portfolio, shall determine without prior consultation with the Trust or the Adviser, what securities and other assets of the Fund will be acquired, held, disposed of or loaned, and place orders or direct the Adviser to place orders, for the purchase or sale of such securities or other assets with brokers, dealers or others, all in conformity with the investment objectives, policies and restrictions and the other statements concerning the Fund in the Trust’s Amended and Restated Agreement and Declaration of Trust, as then in effect, the Trust’s Amended and Restated Bylaws, as then in effect, and the registration statements of the Trust, and to provisions of the Internal Revenue Code, as applicable to each Fund as a regulated investment company. The Sub-Adviser shall cause its officers to attend meetings and furnish oral and written reports, as each Fund may reasonably require, in order to keep the Trustees and appropriate officers of each Fund fully informed as to the condition of the investment portfolio of each Fund. Additionally, the Sub-Adviser shall furnish reports as may be reasonably requested by the Board or the Adviser, including, but not limited to reports relating to the valuation of the Fund’s assets.

Fees. Under the Current Sub-Advisory Agreements and New Sub-Advisory Agreements, each INTECH Fund, Perkins Fund and Janus Asia Equity Fund pays to the applicable Sub-Adviser a sub-advisory fee which is calculated daily and paid monthly. The sub-advisory fee rate under the New Sub-Advisory Agreements is identical to the sub-advisory fee rate under the Current Sub-Advisory Agreements. Certain Perkins Funds and Janus Asia Equity Fund pay a sub-advisory fee rate that may adjust up or down based on such Fund’s performance relative to the cumulative investment record of its benchmark index over a performance measurement period. For each such Fund, the terms of such performance adjustment under the New Sub-Advisory Agreement are identical to the terms of such performance adjustment under the Current Sub-Advisory Agreement. Appendix C to this Proxy Statement sets forth the sub-advisory fee rate applicable to each Fund. Appendix G to this Proxy Statement sets forth the amount of fees paid by the Adviser to the Sub-Adviser with respect to each Fund during each Fund’s most recently ended fiscal year.

Payment of Expenses. Under each Current Sub-Advisory Agreement and New Sub-Advisory Agreement, the Sub-Adviser agrees to pay its own costs and expenses incurred in rendering its services.

Limitation on Liability. The Current Sub-Advisory Agreements and New Sub-Advisory Agreements provide that the Sub-Adviser will not be liable for, and the Adviser will not take any action against the Sub-Adviser to hold the Sub-Adviser liable for, any error of judgment or mistake of law or for any loss arising out of any investment or for any act or omission taken with respect to the Fund except for willful misfeasance, bad faith or gross negligence in the performance of its duties, or by reason of its reckless disregard of its obligations and duties under the agreement and except to the extent otherwise provided by law.

Table of Contents

Continuance. The Current Sub-Advisory Agreement for each Fund continues in effect for successive one-year periods after its initial term, if such continuance is approved in the manner required by the 1940 Act. The New Sub-Advisory Agreement for each Fund will have an initial term until February 1, 2018, and will continue thereafter for successive one-year periods if approved annually in the same manner required under the Current Sub-Advisory Agreements.

Termination. The Current INTECH Sub-Advisory Agreements and New INTECH Sub-Advisory Agreements provide that the agreement may be terminated at any time, without penalty, by the Board, or by the shareholders of the Fund acting by vote of at least a majority of its outstanding voting securities, provided in either case that sixty (60) days’ advance written notice of termination be given to INTECH at its principal place of business. Further, the Current INTECH Sub-Advisory Agreements and New INTECH Sub-Advisory Agreements provide that the agreement may be terminated (i) by the Adviser or by INTECH at any time, without penalty, by giving sixty (60) days’ advance written notice of termination to the other party, or (ii) by the Adviser or the Trust without advance notice if INTECH becomes unable to discharge its duties and obligations under the agreement. In addition, a Fund’s Current INTECH Sub-Advisory Agreement and New INTECH Sub-Advisory Agreement shall terminate, without penalty, upon termination of the Current Advisory Agreement or New Advisory Agreement, as applicable, of such Fund.

The Current Perkins Sub-Advisory Agreements and New Perkins Sub-Advisory Agreements provide that the agreement may be terminated at any time, without penalty, by the Board, or by the shareholders of a Fund acting by vote of at least a majority of its outstanding voting securities, provided in either case that sixty (60) days’ advance written notice of termination be given to Perkins at its principal place of business. Further, the Current Perkins Sub-Advisory Agreements and New Perkins Sub-Advisory Agreements provide that the agreement may be terminated (i) by the Adviser at any time, without penalty, by giving sixty (60) days’ advance written notice of termination to Perkins; (ii) by Perkins at any time, without penalty, by giving ninety (90) days’ advance notice to the Adviser and the Trust, unless the Adviser or the Trust requests additional time to find a replacement for Perkins, in which case Perkins shall allow the additional time requested by the Adviser or the Trust not to exceed ninety (90) days’ beyond the initial 90 days’ notice period unless otherwise agreed to by the Adviser, the Trust and Perkins; or (iii) by the Adviser or the Trust without advance notice if Perkins becomes unable to discharge its duties and obligations under the agreement. In addition, a Fund’s Current Perkins Sub-Advisory Agreement and New Perkins Sub-Advisory Agreement shall terminate, without penalty, upon termination of the Current Advisory Agreement or New Advisory Agreement, as applicable, of such Fund.

The Current Janus Singapore Sub-Advisory Agreement and New Janus Singapore Sub-Advisory Agreement provide that the agreement may be terminated at any time, without penalty, by the Board, or by the shareholders of the Janus Asia Equity Fund acting by vote of at least a majority of its outstanding voting securities, provided in either case that sixty (60) days’ advance written notice of termination be given to Janus Singapore at its principal place of business. Further, the Current Janus Singapore Sub-Advisory Agreement and New Janus Singapore Sub-Advisory Agreement provide that the agreement may be terminated (i) by the Adviser at any time, without penalty, by giving sixty (60) days’ advance written notice of termination to Janus Singapore; (ii) by Janus Singapore at any time, without penalty, by giving ninety (90) days’ advance notice to the Adviser and the Trust, unless the Adviser or the Trust requests additional time to find a replacement for Janus Singapore, in which case Janus Singapore shall allow the additional time requested by the Adviser or the Trust not to exceed ninety (90) days’ beyond the initial 90 days’ notice period unless otherwise agreed to by the Adviser, the Trust and Janus Singapore; or (iii) by the Adviser or the Trust without advance notice if Janus Singapore becomes unable to discharge its duties and obligations under the agreement. In addition, the Janus Asia Equity Fund’s Current Janus Singapore Sub-Advisory Agreement and New Janus Singapore Sub-Advisory Agreement shall terminate, without penalty, upon termination of the Fund’s Current Advisory Agreement or New Advisory Agreement, as applicable.

Interim Sub-Advisory Agreements

In the event shareholders of a Fund do not approve such Fund’s New Advisory Agreement and/or New Sub-Advisory Agreement at the Meeting prior to the closing of the Transaction, an interim sub-advisory agreement between the Adviser and the applicable Sub-Adviser (each an “Interim Sub-Advisory Agreement” and collectively, the “Interim Sub-Advisory Agreements”) will take effect upon the closing of the Transaction. At the December 8, 2016 meeting, the Board, including the Independent Trustees, unanimously approved an Interim Sub-Advisory Agreement for each applicable Fund in order to assure continuity of sub-advisory services to the sub-advised Funds after the Transaction. The terms of each Interim Sub-Advisory Agreement are substantially identical to those of the Current Sub-Advisory Agreements and New Sub-Advisory Agreements, except for the term and escrow provisions described below. The Interim Sub-Advisory Agreement will continue in effect for a term ending on the earlier of 150 days from the closing of the Transaction (the “150-day period”) or when shareholders of a Fund approve the New Advisory Agreement and New Sub-Advisory Agreement. Pursuant to Rule 15a-4 under the 1940 Act,

12

Table of Contents

compensation earned by a Sub-Adviser under an Interim Sub-Advisory Agreement will be held in an interest-bearing escrow account. If shareholders of a Fund approve the New Advisory Agreement and New Sub-Advisory Agreement prior to the end of the 150-day period, the amount held in the escrow account under the Interim Sub-Advisory Agreement will be paid to the Sub-Adviser. If shareholders of a Fund do not approve the New Advisory Agreement and/or New Sub-Advisory Agreement prior to the end of the 150-day period, the Board will take such action as it deems to be in the best interests of the Fund, and the Sub-Adviser will be paid the lesser of its costs incurred in performing its services under the Interim Sub-Advisory Agreement or the total amount in the escrow account, plus interest earned.

PROPOSAL 3

APPROVAL OF INVESTMENT SUB-ADVISORY AGREEMENT WITH HENDERSON INVESTMENT MANAGEMENT LIMITED

(Janus Asia Equity Fund and Janus Global Real Estate Fund)

Background

In connection with the Transaction, the Adviser has evaluated its capabilities, the capabilities of the existing Sub-Advisers and the enhanced capabilities of Janus Henderson upon the closing of the Transaction. With respect to Janus Asia Equity Fund and Janus Global Research Fund (each, an “HIML Fund” and together, the “HIML Funds”), the Adviser determined that it would be in the best interest of the HIML Funds to draw upon the combined resources of Janus Henderson following the Transaction by appointing HIML as sub-adviser to the HIML Funds. With respect to Janus Asia Equity Fund, if approved by shareholders, HIML would become sub-adviser upon the closing of the Transaction and would replace Janus Singapore as sub-adviser to such Fund. With respect to Janus Global Real Estate Fund, HIML would become sub-adviser upon the closing of the Transaction and would be responsible for the day-to-day management of a portion of the investment operations of such Fund subject to the general oversight of Janus Capital. Janus Capital would continue to be responsible for the day-to-day management of a portion of the investment operations of Janus Global Real Estate Fund. Janus Capital believes that HIML provides seasoned resources focused on Asia equities, real estate, and expertise with non-U.S. investments that can benefit the HIML Funds. With respect to Janus Global Real Estate Fund, Janus Capital believes that such Fund will benefit from portions of the Fund’s investment operations being managed by Janus Capital and HIML, based on similarities in investment process and philosophy of the HIML and Janus Capital investment teams and the benefits of maintaining a “multi-local presence” with investment professionals in key markets, pursuant to which the Denver-based Janus Capital investment team will augment the HIML investment team that has investment professionals based in Europe, Asia and the United States.

HIML is an SEC registered investment adviser and is an indirect, wholly-owned subsidiary of Henderson and serves as investment sub-adviser to several mutual funds offered by Henderson. No changes to the investment objectives, policies or restrictions of the HIML Funds are anticipated in connection with the appointment of HIML as sub-adviser. Following the appointment of HIML as sub-adviser, each Fund may experience a higher portfolio turnover rate for a period of time, as portfolio repositioning transactions are made in the discretion of the new portfolio managers. The Funds pay transaction costs, such as brokerage commissions, when buying and selling securities. A higher portfolio turnover rate may result in higher transaction costs, which affect a Fund’s performance. Portfolio turnover may also result in higher taxes when Fund shares are held in a taxable account.

The 1940 Act requires that a new sub-advisory agreement be approved by the Fund’s shareholders in order for it to become effective.

The Proposal

With respect to each HIML Fund, shareholders of the Fund are being asked to approve a new sub-advisory agreement between the Adviser and HIML (each, a “HIML Sub-Advisory Agreement” and collectively, the “HIML Sub-Advisory Agreements”) to take effect immediately after the Closing of the Transaction or shareholder approval, whichever is later.

At the December 8, 2016 Board meeting, and for the reasons discussed below (see “Board Considerations” after this Proposal 3), the Board, all of whom are Independent Trustees, unanimously approved each HIML Sub-Advisory Agreement and recommends that shareholder of each Fund approve the HIML Sub-Advisory Agreement with respect to their Fund. With respect to Janus Asia Equity Fund, the Board approved the termination of the Sub-Advisory Agreement with Janus Singapore concurrently with the effectiveness of the HIML Sub-Advisory Agreement. For additional information regarding the Board’s consideration of the HIML Sub-Advisory Agreements, see “Board Considerations” after this Proposal 3. The form of the HIML Sub-Advisory Agreement is attached hereto as Appendix R.

Summary of Terms of HIML Sub-Advisory Agreement

Each HIML Sub-Advisory Agreement will have an initial term through February 1, 2018 and will continue in effect from year to year thereafter if such continuance is approved for such Fund at least annually in the manner required by the 1940 Act. Below is a summary of certain terms of each HIML Sub-Advisory Agreement.

Sub-Advisory Services. With respect to Janus Asia Equity Fund, the HIML Sub-Advisory Agreement provides that HIML shall manage the investment operations of the Fund and the composition of the Fund’s investment portfolio, With respect to

Table of Contents

Janus Global Real Estate Fund, the HIML Sub-Advisory Agreement provides that HIML shall manage a portion of the investment operations and the composition of a portion of the Fund’s investment portfolio. With respect to Janus Asia Equity Fund and the portion of Janus Global Real Estate Fund managed by HIML, HIML shall determine without prior consultation with the Trust or the Adviser, what securities and other assets of the Fund will be acquired, held, disposed of or loaned, and place orders or direct the Adviser to place orders, for the purchase or sale of such securities or other assets with brokers, dealers or others, all in conformity with the investment objectives, policies and restrictions and the other statements concerning the Fund in the Trust’s Amended and Restated Agreement and Declaration of Trust, as then in effect, the Trust’s Amended and Restated Bylaws, as then in effect, and the registration statements of the Trust, and to provisions of the Internal Revenue Code, as applicable to the Fund as a regulated investment company. HIML shall cause its officers to attend meetings and furnish oral and written reports, as the Fund may reasonably require, in order to keep the Trustees and appropriate officers of the Fund fully informed as to the condition of the investment portfolio of the Fund. Additionally, HIML shall furnish reports as may be reasonably requested by the Board or the Adviser, including, but not limited to reports relating to the valuation of the Fund’s assets.

Fees. Under each HIML Sub-Advisory Agreement, the Adviser will pay HIML a sub-advisory fee out of the investment advisory fee it receives from the Fund. With respect to Janus Asia Equity Fund, the sub-advisory fee will be equal to 50% of the investment advisory fee paid by Janus Asia Equity Fund to the Adviser (plus or minus any performance fee adjustment, and net of reimbursement of expenses incurred or fees waived by the Adviser, or any recoupment of such reimbursement or fee reduction, which shall be shared equally between the Adviser and HIML) pursuant to the New Advisory Agreement which is the same sub-advisory fee rate currently paid by Janus Capital to Janus Singapore. With respect to Janus Global Real Estate Fund, the sub-advisory fee will be equal to one third of the investment advisory fee paid by Janus Global Real Estate Fund to the Adviser (plus or minus any performance fee adjustment, and net of reimbursement of expenses incurred or fees waived by the Adviser, or any recoupment of such reimbursement or fee reduction, which shall be shared equally between the Adviser and HIML) pursuant to the New Advisory Agreement. As a result, the sub-advisory fee paid by the Adviser to HIML will adjust up or down based on the Fund’s performance relative to its benchmark index over the performance measurement period.

There will be no change to the advisory fee rate paid by your Fund to the Adviser in connection with the appointment of HIML as sub-adviser. For additional information regarding the advisory fee paid by the Fund to the Adviser see Appendix C.

Payment of Expenses. Under each HIML Sub-Advisory Agreement, HIML agrees to pay its own costs and expenses incurred in rendering its services.

Limitation on Liability. Each HIML Sub-Advisory Agreement provides that HIML will not be liable for, and the Adviser will not take any action against HIML to hold HIML liable for, any error of judgment or mistake of law or for any loss arising out of any investment or for any act or omission taken with respect to the Fund except for willful misfeasance, bad faith or gross negligence in the performance of its duties, or by reason of its reckless disregard of its obligations and duties under the agreement and except to the extent otherwise provided by law.

Continuance. Each HIML Sub-Advisory Agreement will have an initial term until February 1, 2018, and will continue thereafter for successive one-year periods, if such continuance is specifically approved at least annually in the same manner required by the 1940 Act.

Termination. Each HIML Sub-Advisory Agreement provides that the agreement may be terminated at any time, without penalty, by the Board, or by the shareholders of the Fund acting by vote of at least a majority of its outstanding voting securities, provided in either case that sixty (60) days’ advance written notice of termination be given to HIML at its principal place of business. Further, each HIML Sub-Advisory Agreement provides that the agreement may be terminated (i) by the Adviser at any time, without penalty, by giving sixty (60) days’ advance written notice of termination to HIML; (ii) by HIML at any time, without penalty, by giving ninety (90) days’ advance notice to the Adviser and the Fund, unless the Adviser or the Fund requests additional time to find a replacement for HIML, in which case HIML shall allow the additional time requested by the Adviser or the Fund not to exceed ninety (90) days’ beyond the initial 90 days’ notice period unless otherwise agreed to by the Adviser, the Fund and HIML; or (iii) by the Adviser or the Fund without advance notice if HIML becomes unable to discharge its duties and obligations under the agreement. In addition, the HIML Sub-Advisory Agreement shall terminate, without penalty, upon termination of the New Advisory Agreement of the Fund.

For Janus Asia Equity Fund, the terms of the HIML Sub-Advisory Agreement are substantially similar to those of the Current Janus Singapore Sub-Advisory Agreement, including that the same rate of compensation is paid to HIML by the Adviser that the Adviser currently pays to Janus Singapore.

BOARD CONSIDERATIONS

New Advisory Agreements and New Sub-Advisory Agreements

On September 15, 2016, Janus advised the Board of its intent to seek a strategic combination of its advisory business with Henderson. The Board met with the Chief Executive Officer of Janus, who outlined the proposed combination and the potential benefits to Janus Capital and the Funds. Subsequent to the September 15, 2016 meeting, the Trustees identified a list of basic principles, which they believed should serve as the foundation for their review of the organizational, operational and strategic issues involved with any potential change in control of Janus Capital, the investment adviser to the Funds. These basic principles were communicated to Janus Capital on September 27, 2016, and were intended to be shared with Henderson. On October 3, 2016, Janus announced that it had entered into a definitive Agreement and Plan of Merger with Henderson pursuant to which Janus and Henderson agreed to effect an all-stock merger of equals strategic combination of their respective businesses, with Janus Capital surviving the merger as a direct wholly-owned subsidiary of Henderson. The Board was advised that, subject to certain conditions, the Transaction is currently expected to close during the second quarter of 2017.

As part of its due diligence, the Board developed an initial list of questions related to the proposed transaction, which was provided to Janus Capital on October 6, 2016. At a special Board meeting held on October 19, 2016, the Board considered Janus Capital’s response to the initial information request and met with the management of Janus to discuss the impact of the Transaction on the nature, extent and quality of services Janus Capital is expected to provide to the Funds following the Transaction, addressing, among other matters, the personnel expected to provide such services, and the resources available to do so. After its October 19, 2016 meeting, the Board developed a supplemental request for additional information, which was provided to Janus Capital on October 26, 2016. At another special Board meeting held on November 7-8, 2016, the Board considered Janus Capital’s response to the supplemental information request and again met with the management of Janus and Henderson to discuss the impact of the Transaction on the nature, extent and quality of services Janus Capital is expected to provide to the Funds following the Transaction, and also met with various officers of the Funds and of Janus Capital, including various Fund portfolio managers. After its November 7-8, 2016 meeting, the Board developed a second supplemental request for additional information, which was provided to Janus Capital on November 21, 2016. On December 7-8, 2016, the Board met to consider Janus Capital’s response to the second supplemental information request and to also consider the proposed New Advisory Agreement for each Fund and the New Sub-Advisory Agreement for Funds managed by INTECH, Perkins or Janus Singapore. During each of these meetings, the Board sought additional and clarifying information as it deemed necessary or appropriate. In addition, the Board engaged its independent fee consultant to help evaluate certain of the proposals that the Board was being asked to consider. Throughout the process, the Board had the assistance of its independent legal counsel, who advised them on, among other things, its duties and obligations.

In connection with the Board’s review, Janus Capital provided, and the Board obtained, substantial information regarding the following matters: the management, financial position and business of Henderson; the history of Henderson’s business and operations; the investment performance of the investment companies advised by Henderson; the proposed structure, operations and investment processes of the combined investment management organization after the Transaction and the strategy for operating and growing the business following the Transaction; the future plans of Janus and Henderson with respect to the Funds and any proposed changes to the operations or structure of the Funds; and the future plans of Janus and Henderson with respect to the provision of services to the Funds, and the entities providing such services, including those affiliated with Janus. The Board also received information regarding the terms of the Transaction, anticipated management of the combined organization, the resources that each of Janus and Henderson bring to the combined organization and the process being followed by Janus and Henderson to integrate their organizations. The Board also received information regarding the impact of the Transaction on each of INTECH, Perkins and Janus Singapore.

In connection with the Board’s approval of New Advisory Agreements and New Sub-Advisory Agreements at its December 8, 2016 meeting, the Board also continued its on-going annual process to determine whether to continue the Current Advisory Agreements and the Current Sub-Advisory Agreements. In this regard, the Board received and reviewed information provided by Janus and the respective Sub-Advisers in response to requests of the Board and its independent legal counsel. The Board also received and reviewed information and analysis provided by, and in response to requests of, its independent fee consultant. The Board noted that as part of this annual process, the Board had considered and was in the process of considering, numerous factors, including the nature and quality of services provided by Janus Capital and each Sub-Adviser, as applicable; investment performance, on an absolute basis and relative to appropriate peer groups and one or a combination of market indices; investment management fees, expense ratios and asset sizes of the Funds and peer groups; investment management fees charged to comparable investment companies, separate accounts and non-fund clients; Janus Capital’s profitability from

managing the Funds; fall-out benefits to Janus Capital from its relationship to the Funds, including revenues derived from services provided to the Funds by affiliates of Janus Capital; and the potential benefits to Janus Capital, the Funds of receiving research services from broker/dealer firms in connection with the allocation of portfolio transactions to such firms.

In determining whether to approve the New Advisory Agreement for each Fund and the New Sub-Advisory Agreement for Funds managed by INTECH, Perkins or Janus Singapore in connection with the Transaction, and whether to recommend approval to Fund shareholders, the Board received information and made inquiries into all matters as it deemed appropriate. The Board reviewed and analyzed various factors it deemed relevant, including the following factors, among others, none of which by itself was considered dispositive:

In connection with its deliberations, the Board received assurances from Janus, on behalf of itself and its affiliates (collectively, “Janus”) including the following:

19

Table of Contents

Janus assured the Board that it intended to comply with Section 15(f) of the 1940 Act. Section 15(f) provides a non-exclusive safe harbor for an investment adviser to an investment company or any of its affiliated persons to receive any amount or benefit in connection with a change in control of the investment adviser so long as two conditions are met. First, for a period of three years after the transaction, at least 75% of the board members of the investment company must not be Interested Persons of such investment adviser. The composition of the Board is in compliance with this provision of Section 15(f). In addition, after careful review and consideration, the Board determined that it would be in the best interests of the Funds to add to the Board an individual who currently acts as a non-interested board member of the Henderson Trust. The Board believes that this change in the Board composition will provide perspective and insight relating to experience working with the Henderson organization. The Board’s Nominating and Governance Committee considered a number of candidates and recommended that the Board nominate one proposed new trustee from those candidates who currently act as non-interested board members of the Henderson Trust. The Board approved that trustee nominee to serve on the Board, subject to election by the shareholders of the Funds and contingent on the closing of the Transaction. If the new trustee is elected and serves on the Board, the Board composition would continue to satisfy the provisions of Section 15(f).

To meet the second condition of Section 15(f), an “unfair burden” must not be imposed upon the investment company as a result of such transaction or any express or implied terms, conditions or understandings applicable thereto. The term “unfair burden” is defined in Section 15(f) to include any arrangement during the two-year period after the transaction, whereby the investment adviser, or any interested person of such adviser, receives or is entitled to receive any compensation, directly or indirectly, from the investment company or its shareholders (other than fees for bona fide investment advisory or other services) or from any person in connection with the purchase or sale of securities or other property to, from or on behalf of the investment company (other than bona fide ordinary compensation as principal underwriter for such investment company).

Janus represented that it does not believe that an “unfair burden” will be placed on the Funds as a result of the Transaction. In furtherance thereof, Janus has undertaken to pay the costs of preparing and distributing proxy materials to, and of holding the Meetings of, the Funds’ shareholders, as well as other fees and expenses in connection with the Transaction, including the reasonable fees and expenses of legal counsel and consultants to the Funds and the Trustees. In addition, Janus has agreed, for a period of two years following the closing of the Transaction, (i) not to request any increases to advisory fees for the Funds, other than those proposed to and approved by the Board prior to the close of the Transaction, and (ii) to continue to use the current process by which expense caps are set annually for the Funds.

As a result of its review and consideration of the New Investment Advisory Agreements and New Sub-Advisory Agreements in connection with the Transaction, at a meeting on December 8, 2016, the Board voted unanimously to approve a New Investment Advisory Agreement for each Fund and a New Sub-Advisory Agreement for each Fund managed by INTECH, Perkins or Janus Singapore, and to recommend such agreements to the Funds’ shareholders for their approval.

HIML Sub-Advisory Agreements

The Adviser met with the Trustees on November 7-8, 2016, and December 7-8, 2016, to discuss the HIML Sub-Advisory Agreements. At the meetings, the Trustees also discussed the HIML Sub-Advisory Agreements with their independent counsel in executive session. During the course of these meetings, the Trustees requested and considered such information as they deemed relevant to their deliberations. In addition, at prior meetings and during the course of these meetings the Board also undertook a comprehensive process to evaluate the impact of the Transaction on the nature, quality and extent of services expected to be provided by the Adviser and HIML to each HIML Fund, including after the completion of the Transaction. For a fuller discussion of the Board’s consideration of the approval of a new investment advisory agreement for the HIML Funds in

connection with the Transaction, see “Board Considerations—New Advisory Agreements with the Current Adviser and Sub-Advisers” above.

At a meeting of the Board of Trustees held on December 8, 2016, the Trustees considered the HIML Sub-Advisory Agreements. In determining whether to approve the HIML Sub-Advisory Agreements, and whether to recommend approval to the shareholders of each HIML Fund, the Board received information and made inquiries into all matters as it deemed appropriate. The Board reviewed and analyzed various factors it deemed relevant, including the following factors, among others, none of which by itself was considered dispositive:

As a result of its review and consideration of each HIML Sub-Advisory Agreement and related matters, on December 8, 2016, the Board voted unanimously to approve each HIML Sub-Advisory Agreement and to recommend such agreement to each HIML Fund’s shareholders for their approval.

PROPOSAL 4

TRUSTEE ELECTION

(All Funds)

Introduction

At the Meeting, shareholders of all series of the Trust will be asked to elect an additional individual to the Board of Trustees. Currently, the Board has eight members, each of whom is an Independent Trustee. In connection with the Transaction, the Board has sought to increase the size of the Board to nine members and has nominated Diane L. Wallace (the “Trustee Nominee”) to stand for election as a Trustee.

Ms. Wallace was unanimously approved by the Board to stand for election, upon a recommendation from the Board’s Nominating and Governance Committee, a committee consisting entirely of Independent Trustees, and the nomination was approved by all of the current Independent Trustees.

Ms. Wallace currently serves as a trustee of certain mutual funds advised by HGINA and would qualify to serve as an Independent Trustee. Among other things, the Board considered Ms. Wallace’s background and experience in the financial services industry, including her experience with the Henderson funds, and determined that the addition of Ms. Wallace to the Board would provide valuable continuity and enhance the Board’s oversight of the Trust following the completion of the Transaction. The election by shareholders of the Trustee Nominee will provide the Board with flexibility going forward to replace Trustees as needed without the time and expense of unnecessary proxy solicitation.

The persons named as proxies on the enclosed proxy card(s) will vote for the election of the nominee named below unless the authority to vote for the Trustee Nominee is withheld.

If elected, the Trustee Nominee will serve as a Trustee until the next meeting of the shareholders, if any, called for the purpose of electing all Trustees or until the election and qualification of a successor. If a Trustee sooner dies, resigns, retires (currently expected at the end of the calendar year in which the Trustee turns age 75), or is removed as provided in the organizational documents of the Trust, the Board may, in its discretion and subject to the 1940 Act, select another person to fill the vacant position. If the Trustee Nominee should become unavailable for election at the Meeting due to events not now known or anticipated, the persons named as proxies will vote for such other nominee or nominees as the current Independent Trustees may recommend.

The Trust is not required, and does not intend, to hold annual shareholder meetings for the purpose of electing Trustees. Shareholders also have the right to call a meeting to remove a Trustee or to take other action described in the Trust’s organizational documents. Also, if at any time less than a majority of the Trustees holding office have been elected by the Trust’s shareholders, the Trustees then in office will promptly call a shareholder meeting for the purpose of electing one or more Trustees.

The Trustee Nominee and her background are shown on the following pages. This information includes each Trustee’s and the Trustee Nominee’s name, age, principal occupation(s) and other information about each Trustee and the Trustee Nominee’s professional background, including other directorships the Trustee or the Trustee Nominee holds or held, during the past five years. The address of each Trustee and the Trustee Nominee is 151 Detroit Street, Denver, Colorado 80206. Each Trustee serves, and the Trustee Nominee, if so elected will serve, as a trustee of Janus Aspen Series (“JAS”), another registered investment company advised by Janus Capital (JAS and the Trust, are collectively referred to herein as the “Janus Funds”). Collectively, the Janus Funds consist of 58 series as of December 29, 2016.

General Information Regarding the Board of Trustees

The Trust is governed by the Board of Trustees, which is responsible for and oversees the management and operations of the Trust and each Fund on behalf of Fund shareholders. Each member of the Board is an Independent Trustee, including the Board’s Chairman. The Board’s responsibilities include, but are not limited to, oversight of the Funds’ officers and service providers, including Janus Capital, which is responsible for the Trust’s day-to-day operations. The Trustees approve all of the agreements entered into with the Funds’ service providers, including the investment advisory agreements with Janus Capital and the Funds’ sub-advisers. The Trustees are also responsible for determining or changing the Funds’ investment objectives, policies, and available investment techniques, as well as for overseeing the Trust’s Chief Compliance Officer. In carrying out these responsibilities, the Trustees are assisted by the Trust’s independent auditor (who reports directly to the Trust’s Audit Committee), independent counsel, an independent fee consultant, and other specialists as appropriate, all of whom are selected by the Trustees. The Trustees also meet regularly with and without representatives of Janus Capital or its affiliates present.

The Trustees discharge their responsibilities collectively as a Board, as well as through Board committees, each of which operates pursuant to a Board-approved charter that delineates the specific responsibilities of that committee. For example, the Board as a whole is responsible for oversight of the annual process by which the Board considers and approves each Fund’s investment advisory agreement with Janus Capital, but specific matters related to oversight of the Funds’ independent auditor have been delegated by the Board to its Audit Committee, subject to approval of the Audit Committee’s recommendations by the Board. The members and responsibilities of each Board committee are summarized below. In addition to serving on certain

24

Table of Contents

committees, the Chairman of the Board (“Board Chairman”) is responsible for presiding at all meetings of the Board, and has other duties as may be assigned by the Trustees from time to time. The Board Chairman also serves as the Board’s liaison to Janus Capital with respect to all matters related to the Funds that are not otherwise delegated to the chair of a Board committee. The Board has determined that this leadership structure is appropriate based on (1) the number of Funds overseen and the various investment objectives of those Funds; (2) the manner in which the Funds’ shares are marketed and distributed; and (3) the responsibilities entrusted to Janus Capital and its affiliates to oversee the Trust’s day-to-day operations, including the management of each Fund’s portfolio and the distribution of Fund shares. On an annual basis, the Board conducts a self-evaluation that considers, among other matters, whether the Board and its committees are functioning effectively and whether, given the size and composition of the Board and each of its committees, the Trustees are able to oversee effectively the number of Janus Funds in the complex.

There were 4 regular meetings and 4 special meetings of the Trustees held during the 12 months ended December 31, 2016. Each Trustee attended all of these meetings with few exceptions during that 12-month period. Because the Trust is not required to convene annual shareholder meetings, there is no policy requiring Trustee attendance at such meetings.

Committees of the Board of Trustees

The Board of Trustees has six standing committees that perform specialized functions: an Audit Committee, a Brokerage Committee, an Investment Oversight Committee, a Legal and Regulatory Committee, a Nominating and Governance Committee, and a Pricing Committee. Each committee is comprised entirely of Independent Trustees and has a written charter that delineates its duties and powers. Each committee reviews and evaluates matters as specified in its charter and makes recommendations to the Trustees as it deems appropriate. Each committee may utilize the resources of counsel to the Independent Trustees and the Trust, independent auditors and other experts. The committees normally meet in conjunction with regular meetings of the Trustees but may convene at other times (in person or by telephone) as deemed appropriate or necessary. The membership and chairperson of each committee is appointed by the Trustees upon recommendation of the Trust’s Nominating and Governance Committee.

The Committee’s review of the audit process includes, among other things, the appointment, compensation and oversight of the Trust’s independent auditor, which performs the audits of the Funds’ financial statements, regular meetings and communication with relevant personnel at Janus Capital and the independent auditor, and pre-approval of all audit and non-audit services. The Committee also reviews any significant changes or improvements in accounting and audit processes that have been implemented. The Committee receives reports from Janus Capital’s enterprise risk management and internal audit departments. The Committee also receives annual representations from the Trust’s independent auditor as to its independence. Currently, the members of the Audit Committee are: William D. Cvengros (Chair), Gary A.

In addition, the Nominating and Governance Committee leads the Trustees’ annual self-assessment process. Currently, the members of the Nominating and Governance Committee are: James T. Rothe (Chair), William F. McCalpin, and Linda S. Wolf. The Committee held 7 meetings during the 12 months ended December 31, 2016.

The Committee also provides oversight of all types of derivative instruments used by the Trusts and the currency hedging activities of the Trusts, reviews the reasonableness of valuation procedures, management’s adherence to such procedures, the adequacy of supporting documentation, the frequency and magnitude of pricing errors, and other matters related to pricing the Janus Funds’ securities. Currently, the members of the Pricing Committee are: William D. Stewart (Chair), Raudline Etienne, James T. Rothe, and Linda S. Wolf. The Committee held 3 meetings during the 12 months ended December 31, 2016.

Process for Identifying and Evaluating Trustee Nominees and Nominee Qualifications

The Nominating and Governance Committee of the Board is responsible for identifying and nominating candidates for appointment as Trustees. As stated in the Committee’s charter, (1) the principal criterion for selection of candidates for the Board is the candidate’s ability to contribute to the overall functioning of the Board and to carry out the responsibilities of a Trustee, and (2) the Trustees should, collectively, represent a broad cross section of backgrounds, functional disciplines, and experience. In considering a potential candidate’s qualifications to serve as a Trustee, the Committee may also take into account a variety of other diverse criteria, including, but not limited to (i) knowledge of the investment company industry; (ii) relevant experience; (iii) educational background; (iv) reputation for high ethical standards and personal and professional integrity; (v) financial, technical or other expertise; (vi) time commitment to the performance of duties of a Trustee; (vii) stature commensurate with the responsibility of representing Fund shareholders; and (viii) if a candidate is nominated for an Independent Trustee position, that the person meets the independence criteria established by the 1940 Act and the Governance Procedures and Guidelines adopted by the Trustees.

Consistent with the Trust’s organizational documents and procedures adopted by the Nominating and Governance Committee, the Committee will consider Trustee nominations made by shareholders. Shareholders of a Fund may submit names of potential candidates for consideration by the Committee by submitting their recommendations to the Trust’s Secretary, at the address of the principal executive office of the Trust, in accordance with procedures adopted by the Committee. A copy of such procedures is included as Appendix 1 to the Nominating and Governance Committee Charter attached to this Proxy Statement as Appendix L.

The Committee may use any process it deems appropriate for identifying and evaluating candidates for service as a Trustee, which may include, without limitation, personal interviews, background checks, written submissions by the candidates, third party references and the use of consultants, including professional recruiting firms, which the Committee utilized to assist its efforts to identify and evaluate potential nominees during its most recent search. The Committee will evaluate nominees for a particular vacancy using the same process regardless of whether the nominee is submitted by a Fund shareholder or identified by some other means. On an annual basis, the Board conducts a self-evaluation that considers, among other matters, the contributions of individual Trustees, whether the Board has an appropriate size and the right mix of characteristics, experiences and skills, and whether the age distribution and diversity among the Trustees is appropriate.

After completion of its process to identify and evaluate Trustee nominees, and after giving due consideration to all factors it deemed appropriate, the Committee approved for nomination, and recommended that the Trustees approve for nomination, the Trustee Nominee identified herein. The Committee believes that if elected, the Trustee Nominee qualifies to serve as an Independent Trustee. The Trustee Nominee’s background is detailed above.

The Committee and the Trustees considered the totality of the information available to them, and took into account the specific experience, qualifications, attributes or skills discussed below to conclude that each Trustee and Trustee Nominee should serve as a Trustee, in light of the Trust’s business and structure. In reaching these conclusions, the Committee and the Trustees, in the exercise of their reasonable business judgment, evaluated each Trustee and Trustee Nominee based on the criteria described above, and reviewed the specific experience, qualifications, attributes or skills that each Trustee and Trustee Nominee presented, none of which by itself was considered dispositive.

Board Oversight of Risk Management

Janus Capital, as part of its responsibilities for the day-to-day operations of the Funds, is responsible for day-to-day risk management of the Funds. The Board, as part of its overall oversight responsibilities for the Funds’ operations, oversees Janus Capital’s risk management efforts with respect to the Janus funds. In the exercise of its reasonable business judgment, the Board also separately considers potential risks that may impact the Funds. The Board discharges its oversight duties and considers potential risks in a number of different ways, including, but not limited to, receiving reports on a regular basis, either directly or through an appropriate committee, from Janus Capital and its officers. Reports received include those from, among others, Janus Capital’s (1) senior managers responsible for oversight of global risk, including, for example, those responsible for oversight of cyber risks; (2) senior managers responsible for oversight of portfolio construction and trading risk; (3) Chief Compliance Officer; and (4) Director of Internal Audit. At the time these reports are presented, the Board or the committee receiving the report will, as it deems necessary, invite the presenter to participate in an executive session to discuss matters outside the presence of any other officers or representatives of Janus Capital or its affiliates. The Board also receives reports from other entities and individuals unaffiliated with Janus Capital, including reports from the Funds’ other service providers and from independent consultants hired by the Board.

Various Board committees also will consider particular risk items as the committee addresses items and issues specific to the jurisdiction of that committee. For example, the Pricing Committee will consider valuation risk as part of its regular oversight responsibilities, and similarly, the Brokerage Committee will consider counterparty risk associated with the Funds’

27

portfolio transactions. The Board also may be apprised of particular risk management matters in connection with its general oversight and approval of various Fund matters brought before the Board.

The Board has appointed a Chief Compliance Officer for the Funds (“Fund CCO”) who (1) reports directly to the Board and (2) provides a comprehensive written report annually and presents quarterly at the Board’s regular meetings. The Fund CCO, who also serves as Janus Capital’s Chief Compliance Officer, discusses relevant risk issues that may impact the Funds and/or Janus Capital’s services to the Funds, and routinely meets with the Board in private without representatives of Janus Capital or its affiliates present. The Fund CCO also provides the Board with updates on the application of the Funds’ compliance policies and procedures, including how these procedures are designed to mitigate risk and what, if any, changes have been made to enhance the procedures. The Fund CCO may also report to the Board on an ad hoc basis in the event that he &identifies issues associated with the Funds’ compliance policies and procedures that could expose the Funds to additional risk or adversely impact the ability of Janus Capital to provide services to the Funds.

The Board believes that its leadership structure permits it to effectively discharge its oversight responsibilities with respect to the Funds’ risk management process.

Trustee Share Ownership

Under the Trust’s Governance Procedures and Guidelines, the Trustees are expected to invest in one or more (but not necessarily all) funds advised by Janus Capital for which they serve as Trustee, to the extent they are directly eligible to do so. For each Trustee, these investments are expected, in the aggregate and at a minimum, to equal median Trustee annual compensation with an allowance for new Trustees to reach this level of investment over time. These investments may include amounts held under a deferred compensation plan that are valued based on “shadow investments” in such funds. Such investments, including the amount and which funds, are dictated by each Trustee’s individual financial circumstances and investment goals.

The dollar range of equity securities beneficially owned by each Trustee and Trustee Nominee in each Fund and all Janus Funds overseen by the Trustee as of December 31, 2016 in the aggregate is set forth in Appendix H to this Proxy Statement.

Compensation of Trustees

The Trust pays each Independent Trustee an annual retainer plus a fee for each regular in-person meeting of the Trustees attended, a fee for in-person meetings of committees attended if convened on a date other than that of a regularly scheduled meeting, and a fee for telephone meetings of the Trustees and committees. In addition, committee chairs/leads and the Chairman of the Board of Trustees receive an additional supplemental retainer. Each current Independent Trustee also receives fees from other Janus funds for serving as Trustee of those funds and those amounts are included below. Janus Capital pays any Trustee not considered an “independent” Trustee, for their services as a Trustee. All of the Trustees and the Trustee Nominee are “independent;” therefore, none of the Trustees are paid by Janus Capital. The Trust and other funds managed by Janus Capital pay all or a portion of the compensation and related expenses of the Fund CCO and compliance staff, as well as certain Fund officers and Janus Capital employees, as authorized from time to time by the Trustees.

The Board’s Nominating and Governance Committee, which consists solely of Independent Trustees, annually reviews and recommends to the Independent Trustees any changes to compensation paid by the Funds to the Independent Trustees. The Independent Trustees also meet at least annually to review their fees in connection with the recommendations of the Nominating and Governance Committee, to ensure that such fees continue to be appropriate in light of the Trustees’ responsibilities as well as in relation to fees paid to trustees of other similarly situated mutual fund complexes.

The tables set forth in Appendix I to this Proxy Statement show, for each Trustee, the compensation paid by each Fund to each Trustee for its last fiscal year, as well as the total compensation paid by all Janus Funds to each Trustee for the calendar year ended December 31, 2016.

Officers of the Trust

The officers of the Trust and their principal occupations are set forth in Appendix J to this Proxy Statement.

Shareholder Approval

Election of the Trustee Nominee will be determined by the affirmative vote of a plurality (the greatest number of affirmative votes) of the shares of all funds of the Trust, including all Funds listed in this Proxy Statement and each other series of the Trust for which votes are being solicited pursuant to separate proxy statements.

28

Table of Contents

For purposes of determining the election of the Trustee Nominee, abstentions and broker non-votes will have no effect on the outcome of the vote and, assuming the presence of a quorum, votes not cast or withheld will have no effect on the outcome of the vote.

Under a plurality voting standard the Trustee Nominee receiving the greatest number of affirmative votes will be elected. Because a single Trustee Nominee has been nominated to fill the vacancy and is unopposed, assuming the presence of a quorum, the Trustee Nominee is expected to be elected.

If elected by shareholders, and assuming consummation of the Transaction, it is expected that the Trustee Nominee will be seated as a Trustee of the Trust prior to the first meeting of the Board of Trustees of the Trust held after the consummation of the Transaction. The election of the Trustee Nominee is contingent on the closing of the Transaction. If the Transaction is not consummated, the Trustee Nominee will not join the Board of Trustees.

The Board unanimously recommends that shareholders of the Trust vote FOR the Trustee Nominee.

PROPOSAL 5

APPROVAL OF MANAGER OF MANAGERS PROPOSAL

(All Funds except Janus Adaptive Global Allocation Fund and

INTECH Emerging Markets Managed Volatility Fund)

The Board has approved, and recommends that shareholders approve, a proposal authorizing the Adviser to enter into and materially amend sub-advisory agreements in the future with wholly-owned sub-advisers and unaffiliated sub-advisers, with the approval of the Board, but without obtaining additional shareholder approval (the “Manager of Managers Proposal”).

The Manager of Managers Proposal

Shareholder Approval of Sub-Advisory Agreements. Federal securities laws generally require that shareholders approve agreements with a sub-adviser. Shareholder approval also is required if the terms of existing sub-advisory agreements are changed materially or if there is a change in control of the sub-adviser. In order to obtain shareholder approval, a fund must call and conduct shareholder meetings, prepare and distribute proxy materials and solicit votes from shareholders. The process can be costly and time-consuming. The Board believes that it is in the Funds’ best interests if the Board represents their interests in approving or rejecting recommendations made by the Adviser regarding sub-advisers. This approach will avoid the costs and delays associated with holding shareholder meetings to obtain approval for future changes.

SEC Exemptive Order. On July 29, 2014, the SEC granted an order exempting the Trust and the Adviser from the federal securities law requirements to obtain shareholder approval regarding sub-advisory agreements between Janus Capital and wholly-owned sub-advisers and unaffiliated sub-advisers (the “SEC Exemptive Order”). The SEC Exemptive Order permits the Adviser to select sub-advisers to manage all or a portion of the assets of a Fund and enter into sub-advisory agreements with sub-advisers, and materially amend sub-advisory agreements with sub-advisers, subject to the approval of the Board, including a majority of the Independent Trustees, without obtaining shareholder approval. Before a Fund may rely on the SEC Exemptive Order, the operation of the Fund in the manner permitted by the SEC Exemptive Order must be approved by shareholders.

In accordance with the SEC Exemptive Order, the Adviser will provide general management services, including overall supervisory responsibility for the general management and investment of the Fund’s assets. Subject to review and approval of the Board, the Adviser will (a) set a Fund’s overall investment strategies, (b) evaluate, select, and recommend sub-advisers to manage all or a portion of a Fund’s assets, and (c) implement procedures reasonably designed to ensure that sub-advisers comply with a Fund’s investment objective, policies and restrictions. Subject to review by the Board, the Adviser will (a) when appropriate, allocate and reallocate a Fund’s assets among multiple sub-advisers; and (b) monitor and evaluate the performance of sub-advisers.

Under the SEC Exemptive Order, the Trust and the Adviser are subject to several conditions imposed by the SEC to ensure that the interests of the Funds’ shareholders are adequately protected. Among these conditions are that within 90 days of the hiring of a new sub-adviser, a Fund will provide shareholders with an information statement, or with a notice of the availability of such information statement, that contains substantially the same information about the sub-adviser, the sub-advisory agreement and the sub-advisory fee that the Fund would otherwise have been required to send to shareholders in a proxy statement.

Shareholder approval of the Manager of Managers Proposal will not result in an increase or decrease in the total amount of investment advisory fees that would be paid by a Fund to the Adviser.

Board Considerations

The Board believes that it is in the best interest of each Fund to afford the Adviser the flexibility to provide investment advisory services to each Fund through one or more sub-advisers that have particular expertise in the type of investments in which a Fund invests.

As described above, without the ability to utilize the SEC Exemptive Order, in order for the Adviser to appoint a new sub-adviser or modify a sub-advisory agreement materially, the Board must call and hold a shareholder meeting of that Fund, create and distribute proxy materials and solicit votes from the Fund’s shareholders. This process is time consuming and costly. Without the delay inherent in holding shareholder meetings, the Adviser would be able to act more quickly to appoint a new sub-adviser if and when the Board and the Adviser believe that the appointment would benefit the Fund. The Board believes that granting the Adviser (subject to review and approval by the Board) maximum flexibility to select sub-advisers, without incurring the delay or expense of obtaining further shareholder approval, is in the best interest of the Funds because it will allow each Fund to operate more efficiently.

30

Table of Contents

In addition, the Board believes that it is appropriate to vest the selection of sub-advisers in the Adviser (subject to review and approval by the Board) in light of the Adviser’s investment advisory expertise and its experience in selecting sub-advisers. The Board believes that if in the future it becomes appropriate to add or change a sub-adviser to your Fund, it can access this expertise and experience in ways that can add value to the Fund and its shareholders.

Although no new sub-advisory arrangements or changes to any Fund’s existing sub-advisory arrangement are being recommended in connection with the Transaction, except for Janus Asia Equity Fund and Janus Global Real Estate Fund (described further in Proposal 3), the Adviser expects to continue to evaluate these relationships, including evaluating the capabilities of the existing Sub-Advisers, the capabilities of other possible sub-advisers and the enhanced capabilities of Janus Henderson, assuming the Transaction occurs. If that evaluation results in a recommendation to implement a new sub-advisory relationship or change any existing sub-advisory relationship, either in connection with the Transaction or separately, that recommendation could not be implemented without Board approval.

Finally, the Board believes that it will retain sufficient oversight of each Fund’s sub-advisory arrangements to seek to ensure that shareholders’ interests are protected whenever the Adviser selects a sub-adviser or modifies a sub-advisory agreement. The Board will continue to evaluate and to approve all proposed sub-advisory agreements, as well as any proposed modifications to existing sub-advisory agreements. In doing so, the Trustees will analyze such factors that they consider to be relevant to the determination. The terms of each sub-advisory agreement will include those required by applicable provisions of the 1940 Act, except for the specific provisions of the 1940 Act from which the SEC Exemptive Order provides relief.

Shareholder Approval

To become effective with respect to a Fund, the Manager of Managers Proposal must be approved by a 1940 Act Majority (as defined herein) of the Fund, with all classes of shares voting together as a single class. For purposes of determining the approval of the Manager of Managers Proposal, abstentions and broker non-votes will have the same effect as shares voted against the proposal.

An unfavorable vote on the Manager of Managers Proposal by the shareholders of one Fund will not affect the implementation of the Manager of Managers Proposal by another Fund if the Manager of Manager Proposal is approved by the shareholders of that Fund.

Shareholder approval of the Manager of Managers Proposal is not being sought with respect to Janus Adaptive Global Allocation Fund and INTECH Emerging Markets Managed Volatility Fund, as such Funds have already implemented the manager of managers structure at their inception.

If shareholders of a Fund approve the Manager of Managers Proposal, the Proposal will take effect whether or not the Transaction is consummated.

The Board unanimously recommends that shareholders of each Fund vote FOR approval of the Manager of Managers Proposal.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Based on the Audit Committee’s recommendation, the Board of Trustees, all of whom are Independent Trustees, selected PricewaterhouseCoopers LLP (“PwC”) as the Trust’s independent registered public accounting firm during the Trust’s current fiscal year. In accordance with Independence Standards Board Standard No. 1 (“ISB No. 1”), PwC has confirmed to the Trust’s Audit Committee that it is an independent registered accounting firm with respect to the Funds. Representatives of PwC will be available at the Meeting to answer appropriate questions concerning the Trust’s financial statements and will have an opportunity to make a statement if they so choose.

Audit Fees. The aggregate fees billed for professional services rendered by PwC for the audit of annual financial statements or services that are normally provided by PwC in connection with statutory and regulatory filings or engagements for the fiscal years ending in 2016 and 2015 for each Fund and Janus Capital or entities controlling, controlled by, or under common control with Janus Capital that provide ongoing services to the Funds (collectively, “Fund Service Providers”), are listed in the tables set forth in Appendix K to this Proxy Statement.

Audit-Related Fees. The aggregate fees billed for assurance and related services by PwC that are reasonably related to the performance of the audit of the financial statements and are not reported under “Audit Fees” above for the fiscal years ending in 2016 and 2015 for each Fund and the Fund Service Providers are listed in the tables set forth in Appendix K to this Proxy Statement. The nature of the services comprising the fees disclosed under this category includes the review of semiannual reports to shareholders.

Tax Fees. The aggregate fees billed for professional services rendered by PwC for tax compliance, tax advice, and tax planning for the fiscal years ending in 2016 and 2015 for each Fund and the Fund Service Providers are listed in the tables set forth in Appendix K to this Proxy Statement. The nature of the services comprising the fees disclosed under this category includes tax compliance, tax planning, tax advice, and corporate actions review.

All Other Fees. The aggregate fees billed for products and services provided by PwC, other than the services reported in “Audit Fees,” “Audit-Related Fees,” and “Tax Fees” above, for the fiscal years ending in 2016 and 2015 for each Fund and the Fund Service Providers are listed in the tables set forth in Appendix K to this Proxy Statement. The nature of the services comprising the fees disclosed under this category includes the review of semiannual reports to shareholders, an annual study and evaluation of internal accounting controls, training, registration statement review, and Qualified Foreign Individual Investor (“QFII”) services.

Pre-Approval of Certain Services. The Trust’s Audit Committee Charter requires the Audit Committee to pre-approve any engagement of PwC (i) to provide audit or non-audit services to the Trust or (ii) to provide non-audit services to the Fund Service Providers, if the engagement relates directly to the operations and financial reporting of the Trust, except for those non-audit services that were subject to the pre-approval exception under Rule 2-01 of Regulation S-X (the “Pre-Approval Exception”). The Chair of the Audit Committee or, if the Chair is unavailable, another member of the Audit Committee who is an Independent Trustee, may grant the pre-approval. All such delegated pre-approvals must be presented to the Audit Committee no later than the next Audit Committee meeting.

None of the services rendered by PwC to the Funds or to Janus Capital (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser) or any Fund Service Providers for the fiscal years ending in 2016 and 2015 were pre-approved by the Audit Committee pursuant to the Pre-Approval Exception.

Non-Audit Fees. The aggregate non-audit fees billed by PwC for services rendered to the Trust, and rendered to Janus Capital (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any Fund Service Providers for the fiscal years ending in 2016 and 2015 are listed in the tables set forth in Appendix K to this Proxy Statement.

The Audit Committee has considered whether the provision of non-audit services that were rendered to Janus Capital (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and Fund Service Providers that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining PwC’s independence.

ADDITIONAL INFORMATION ABOUT THE MEETING

Quorum and Voting

Each holder of a whole or fractional share shall be entitled to one vote for each whole dollar and a proportionate fractional vote for each fractional dollar of net asset value of shares held in such shareholder’s name as of the Record Date. If you are not the owner of record, but your shares are instead held for your benefit by a financial intermediary such as a retirement plan service provider, broker-dealer, bank trust department, insurance company, or other financial intermediary, that financial intermediary may request that you provide instruction on how to vote the shares you beneficially own. Your financial intermediary will provide you with additional information.

Thirty percent of the outstanding shares entitled to vote at the Meeting with respect to each Fund shall be a quorum for the transaction of business by that Fund at the Meeting. Any lesser number is sufficient for adjournments. Quorum with respect to each proposal is described in greater detail below. In the event that the necessary quorum to transact business is not present or the vote required to approve a proposal is not obtained at the Meeting with respect to each Fund, the persons named as proxies may propose one or more adjournments or postponements of the Meeting, in accordance with applicable law, to permit further solicitation of proxies with respect to the proposal. Any such adjournment or postponement as to the proposal will require the affirmative vote of the holders of a majority of the shares of the applicable Fund, present in person or by proxy at the Meeting. If a quorum is not present or the vote required to approve a proposal is not obtained, the persons named as proxies will vote those proxies for the Fund (excluding broker non-votes and abstentions) in favor of such adjournment or postponement if they determine additional solicitation is warranted and in the interest of the Fund.

“Broker non-votes” are shares held by a broker or nominee for which an executed proxy is received by a Fund, but are not voted because instructions have not been received from beneficial owners or persons entitled to vote, and the broker or nominee does not have discretionary voting power. For purposes of voting on a proposal, abstentions and “broker non-votes” will be counted as present for purposes of determining whether a quorum is present, but do not represent votes cast in favor of an adjournment, postponement, or a proposal. Therefore, if your shares are held through a broker or other nominee, it is important for you to instruct the broker or nominee how to vote your shares.

Certain funds in the Janus fund complex are considered “fund of funds” and invest their assets in the Janus funds. Such funds of funds will vote any shares of the Funds for and against any matter in the same proportion as the votes of other shareholders of the underlying funds.

Proposal 1: Approval of New Investment Advisory Agreement. Shareholders of each Fund will vote separately on Proposal 1. To become effective with respect to a Fund, the New Advisory Agreements require the affirmative vote of a 1940 Act Majority of the applicable Fund, with all classes of shares voting together as a single class. A 1940 Act Majority means the lesser of the vote of (i) 67% or more of the shares of the Fund entitled to vote thereon present at the meeting if the holders of more than 50% of such outstanding shares are present in person or represented by proxy; or (ii) more than 50% of such outstanding shares of the Fund entitled to vote thereon. The shares of each Fund will be counted using dollar-based voting. This means that each share of a Fund will represent a number of votes equal to that share’s net asset value on the record date. For purposes of determining the approval of the New Advisory Agreements, abstentions and broker non-votes will have the same effect as shares voted against the proposal.

An unfavorable vote on the proposal to approve the New Advisory Agreement by the shareholders of one Fund will not affect the implementation of the proposal by another Fund if the proposal is approved by the shareholders of that Fund. However, the proposal will only take effect upon the closing of the Transaction, which is conditioned upon obtaining the approval of new investment advisory agreements by shareholders of Janus funds representing a specified percentage of assets under management.

Proposal 2: Approval of New Investment Sub-Advisory Agreement with Current Sub-Adviser. Shareholders of each INTECH Fund, each Perkins Fund and Janus Asia Equity Fund will vote separately on Proposal 2. To become effective with respect to a Fund, the New Sub-Advisory Agreement must be approved by a 1940 Act Majority of the applicable Fund, with all classes of shares voting together as a single class. The shares of each Fund will be counted using dollar-based voting. This means that each share of a Fund will represent the number of votes equal to that share’s net asset value on the record date. For purposes of determining the approval of each New Sub-Advisory Agreement, abstentions and broker non-votes will have the same effect as shares voted against the proposal.

Table of Contents

An unfavorable vote on the proposal to approve the New Sub-Advisory Agreement by the shareholders of one Fund will not affect the implementation of the proposal by another Fund if the proposal is approved by the shareholders of that Fund. However, the proposal will only take effect upon the closing of the Transaction, which is conditioned upon obtaining the approval of new investment advisory agreements by shareholders of Janus funds representing a specified percentage of assets under management.

Proposal 3: Approval of HIML Sub-Advisory Agreement. Shareholders of each HIML Fund will vote separately on Proposal 3. To become effective with respect to a Fund, the HIML Sub-Advisory Agreement must be approved by a 1940 Act Majority of the Fund, with all classes of shares voting together as a single class. The shares of each Fund will be counted using dollar-based voting. This means that each share of a Fund will represent a number of votes equal to that share’s net asset value on the record date. For purposes of determining the approval of the HIML Sub-Advisory Agreement, abstentions and broker non-votes will have the same effect as shares voted against the proposal.

An unfavorable vote on the proposal to approve the HIML Sub-Advisory Agreement by the shareholders of one Fund will not affect the implementation of the proposal by the other Fund if the proposal is approved by the shareholders of that Fund. However, the proposal will only take effect upon the closing of the Transaction, which is conditioned upon obtaining the approval of new investment advisory agreements by shareholders of Janus funds representing a specified percentage of assets under management.

Proposal 4: Trustee Election. Election of an additional Trustee will be determined by the affirmative vote of a plurality (the greatest number of affirmative votes) of the shares with respect to each fund in the Trust. All series of the Trust, including certain funds not included in this Proxy Statement, are being solicited with respect to the election of the Trustee Nominee pursuant to separate proxy statements. The presence in person or by proxy of the holders of record of 30% of the aggregate total shares entitled to vote of all funds in the Trust constitutes a quorum at the Meeting with respect to this Proposal 4, with all classes of shares of a fund voting together as a single class.

Proposal 5: Approval of Manager of Managers Proposal. Shareholders of each Fund (except for INTECH Emerging Markets Managed Volatility Fund and Janus Adaptive Global Allocation Fund) will vote separately on Proposal 5. To become effective with respect to a Fund, the Manager of Managers Proposal must be approved by a 1940 Act Majority of the Fund, with all classes of shares voting together as a single class. The shares of each Fund will be counted using dollar-based voting. This means that each share of a Fund will represent the number of votes equal to that share’s net asset value on the record date. For purposes of determining the approval of the Manager of Managers Proposal, abstentions and broker non-votes will have the same effect as shares voted against the proposal.

An unfavorable vote on the Manager of Managers Proposal by the shareholders of one Fund will not affect the implementation of the Manager of Managers Proposal by another Fund if the Manager of Managers Proposal is approved by the shareholders of that Fund.

Fund Share Ownership

The number of outstanding shares and net assets of each class of each Fund, as applicable, as of the close of business on the Record Date, is included in Appendix A to this Proxy Statement.

Beneficial owners of 5% or more of the outstanding shares of each class of each Fund are provided in Appendix M to this Proxy Statement. To the best knowledge of the Trust, no person or entity beneficially owned more than 5% of the outstanding shares of any class of a Fund except as stated in Appendix M. To the best knowledge of the Trust, entities shown as owning 25% or more of a Fund, unless otherwise indicated, are not the beneficial owners of such shares.

Solicitation of Proxies

Janus Capital will pay the fees and expenses related to each proposal, including the cost of the preparation of these proxy materials and their distribution, and all other costs incurred with the solicitation of proxies, the Meeting, including any additional solicitation made by letter, telephone, or otherwise.

In addition to solicitation of proxies by mail, certain officers and representatives of the Trust, certain officers and employees of the Adviser or its affiliates, and certain financial services firms and their representatives, without extra compensation, or a solicitor, may conduct additional solicitations personally, by telephone, U.S. mail, verbal, internet, email, or by any other means available.

Table of Contents

Janus Capital has engaged Computershare, a professional proxy solicitation firm, to assist in the solicitation of proxies for the Funds, at an estimated cost of $15,543,000 plus any out-of-pocket expenses. Such expenses will be paid by Janus Capital. Among other things, Computershare will be: (i) required to maintain the confidentiality of all shareholder information; (ii) prohibited from selling or otherwise disclosing shareholder information to any third party; and (iii) required to comply with applicable telemarketing laws.

Brokers, banks, and other fiduciaries may be required to forward soliciting material to their principals on behalf of a Fund and to obtain authorization for the execution of proxies. To the extent Janus Capital or a Fund would have directly borne the expenses for those services, Janus Capital will reimburse these intermediaries for their expenses. The Board has determined that the use of this Proxy Statement is in the best interest of each Fund in light of the similar proposals being considered and voted on by the shareholders of each Fund. Certain other Janus funds, not listed in this Proxy Statement, will also hold meetings of shareholders with similar proposals. If you were also a shareholder of record of one or more of those other funds on the record date established for the meetings of shareholders of such other funds, you will receive a separate proxy statement and proxy card(s) relating to those funds.

As the Meeting date approaches, certain shareholders whose votes have not been received may receive telephone calls from a representative of Computershare. Authorization to permit Computershare to execute proxies may be obtained by telephonic or electronically transmitted instructions from shareholders of each Fund. Proxies that are obtained telephonically will be recorded in accordance with the procedures described below. Janus Capital believes that these procedures are reasonably designed to ensure that both the identity of the shareholder casting the vote and the voting instructions of the shareholder are accurately determined.

In all cases where a telephonic proxy is solicited, the Computershare representative is required to ask for each shareholder’s full name, address, title (if the shareholder is authorized to act on behalf of an entity, such as a corporation), and to confirm that the shareholder has received the Proxy Statement and proxy card(s) in the mail. If the information solicited agrees with the information provided to Computershare, then Computershare’s representative has the responsibility to explain the process, and ask for the shareholder’s instructions on the proposals. Although the Computershare representative is permitted to answer questions about the process, he or she is not permitted to recommend to the shareholder how to vote. The Computershare representative may read the recommendation set forth in this Proxy Statement. The Computershare representative will record the shareholder’s instructions. Within 72 hours, the shareholder will be sent a confirmation of his or her vote asking the shareholder to call 1-866-492-0863 immediately if his or her instructions are not accurately reflected in the confirmation.

Telephone Touch-Tone Voting. Shareholders may provide their voting instructions through telephone touch-tone voting by following the instructions on the enclosed proxy card(s). Shareholders will have an opportunity to review their voting instructions and make any necessary changes before submitting their voting instructions and terminating their telephone call.

Internet Voting. Shareholders may provide their voting instructions through Internet voting by following the instructions on the enclosed proxy card(s). Shareholders who vote via the Internet, in addition to confirming their voting instructions prior to submission and terminating their Internet voting session, will, upon request, receive an e-mail confirming their voting instructions.

If a shareholder wishes to participate in the Meeting but does not wish to give a proxy by telephone or via the Internet, the shareholder may still submit the proxy card(s) originally sent with the Proxy Statement in the postage-paid envelope provided or otherwise mailed or provided to the shareholder, or attend the Meeting in person. Shareholders requiring additional information regarding the proxy or replacement proxy card(s) may contact Computershare at 1-866-492-0863. Any proxy given by a shareholder is revocable until voted at the Meeting.

Revoking a Proxy. Any shareholder submitting a proxy has the power to revoke it at any time before it is exercised at the Meeting by submitting to the Secretary of the Trust at 151 Detroit Street, Denver, Colorado 80206, a written notice of revocation or a subsequently executed proxy or voting instruction, or by attending the Meeting and voting in person. All properly executed and unrevoked proxies received in time for the Meeting will be voted as specified in the proxy or, if no specification is made, will be voted FOR the proposal(s), as described in this Proxy Statement.

Shares Held by Accounts of Insurance Companies. Shares of the Funds may be held by certain separate accounts of insurance companies to fund benefits payable under certain variable annuity contracts and variable life insurance policies. Your insurance company may request that you provide it with voting instructions for your beneficially held shares of any such separate account. If you do not provide voting instructions to your insurance company, it may vote all of your beneficially held

shares in that separate account in the same proportions as the voting actually received from its other variable contract holders for that separate account.

Attending the Meeting. If you wish to attend the Meeting and vote in person, you will be able to do so. If you intend to attend the Meeting in person and you are a record holder of a Fund’s shares, in order to gain admission you may be asked to show photographic identification, such as your driver’s license. If you intend to attend the Meeting in person and you hold your shares through a broker, bank or other intermediary, in order to gain admission you may be asked to show photographic identification, such as your driver’s license, and satisfactory proof of ownership of shares of a Fund, such as your voting instruction form (or a copy thereof) or broker’s statement indicating ownership as of a recent date. If you hold your shares in a brokerage account or through a bank or other intermediary you will not be able to vote in person at the Meeting unless you have previously requested and obtained a “legal proxy” from your broker, bank or other intermediary and present it at the Meeting. You may contact Computershare at 1-866-492-0863 to obtain directions to the site of the Meeting.

Shareholder Proposals for Subsequent Meetings

The Trust is not required, and do not intend, to hold annual shareholder meetings. Shareholder meetings may be called from time to time as described in the Amended and Restated Agreement and Declaration of Trust and the Amended and Restated Bylaws of the Trust.

Under the proxy rules of the SEC, shareholder proposals that meet certain conditions may be included in a Fund’s proxy statement for a particular meeting. Those rules currently require that for future meetings, the shareholder must be a record or beneficial owner of Fund shares either (i) with a value of at least $2,000 or (ii) in an amount representing at least 1% of the Fund’s securities to be voted at the time the proposal is submitted and for one year prior thereto, and must continue to own such shares through the date on which the meeting is held. Another requirement relates to the timely receipt by a Fund of any such proposal. Under those rules, a proposal must have been submitted within a reasonable time before the Fund began to print and mail this Proxy Statement in order to be included in this Proxy Statement. A proposal submitted for inclusion in a Fund’s proxy material for the next special meeting after the meeting to which this Proxy Statement relates must be received by the Fund within a reasonable time before the Fund begins to print and mail the proxy materials for that meeting.

A shareholder wishing to submit a proposal for inclusion in a proxy statement subsequent to the Meeting, if any, should send the written proposal to the Secretary of the Trust at 151 Detroit Street, Denver, Colorado 80206, within a reasonable time before a Fund begins to print and mail the proxy materials for that meeting. Notice of shareholder proposals to be presented at the Meeting must have been received within a reasonable time before the Funds began to mail this Proxy Statement. The timely submission of a proposal does not guarantee its inclusion in the proxy materials.

Shareholder Communications

The Trustees provide for shareholders to send written communications to the Trustees via regular mail. Written communications to the Trustees, or to an individual Trustee, should be sent to the attention of the Trust’s Secretary at the address of the Trust’s principal executive office. All such communications received by the Trust’s Secretary shall be promptly forwarded to the individual Trustee to whom they are addressed or to the full Board of Trustees, as applicable. If a communication does not indicate a specific Trustee, it will be sent to the Chairperson of the Nominating and Governance Committee and the independent counsel to the Trustees for further distribution, as deemed appropriate by such persons. The Trustees may further develop and refine this process as deemed necessary or desirable.

Reports to Shareholders and Financial Statements

The annual report to shareholders of the Funds, including financial statements of each Fund, has previously been sent to shareholders. The Funds provide annual and semiannual reports to their shareholders that highlight relevant information, including investment results and a review of portfolio changes. Additional copies of the Funds’ most recent annual report and any more recent semiannual report are available, without charge, by calling a Janus representative at 1-877-335-2687 (or 1-800-525-3713 if you hold shares directly with Janus Services), via the Internet at janus.com/info (or janus.com/reports if you hold shares directly with Janus Services), or by sending a written request to the Secretary of the Trust at 151 Detroit Street, Denver, Colorado 80206.

To avoid sending duplicate copies of materials to households, the Funds may mail only one copy of each report or this Proxy Statement to shareholders having the same last name and address on the Funds’ records. The consolidation of these mailings benefits the Funds through reduced mailing expenses. With respect to Class D Shares, if a shareholder wants to receive multiple copies of these materials or to receive only one copy in the future, the shareholder should contact the Funds’ transfer

agent, Janus Services, at 1-800-525-3713 or notify the Funds’ transfer agent in writing at P.O. Box 55932, Boston, Massachusetts 02205-5932.

Other Matters to Come Before the Meeting

The Board of Trustees is not aware of any matters that will be presented for action at the Meeting other than the matters described in this Proxy Statement. Should any other matter requiring a vote of shareholders arise, the proxy in the accompanying form will confer upon the person or persons entitled to vote the shares represented by such proxy the discretionary authority to vote the shares as to any other matters, in accordance with their best judgment in the interest of the Trust and/or Funds.

Please vote by Internet or telephone promptly, or complete, date, sign and return the enclosed proxy card(s). No postage is required if you mail your proxy card(s) in the United States.

By Order of the Board of Trustees,

Bruce L. Koepfgen

President and Chief Executive Officer of
