Sales of a Fund’s shares shall be made only to investors residing in those states in which such Fund is registered. After effectiveness of each Fund’s registration statement, Distributor will hold itself available to receive, as agent for the Fund, and will receive by mail, telex, telephone, or such other method as may be agreed upon between Distributor



and Issuer, orders for the purchase of Fund shares, and will accept or reject such orders on behalf of the Fund in accordance with the provisions of the applicable Fund’s prospectus. Distributor will be available to transmit orders, as promptly as possible after it accepts such orders, to the Fund’s transfer agent for processing at the shares’ net asset value next determined in accordance with the prospectuses.

All shares sold by Distributor under this Agreement shall be sold at the offering price of such shares, consisting of the net asset value per share (“Net Asset Value”) plus any applicable load, determined in the manner described in each Fund’s prospectus, as it may be amended from time to time, next computed after the order is accepted by Distributor, or one or more of its affiliates or designees. Each Fund shall determine and promptly furnish to Distributor a statement of the Net Asset Value of each class of the Fund’s shares at least once each day that the Fund is open for business, as described in its current prospectus.
b.    Promotion Support. Each Fund shall furnish to Distributor for use in connection with the sale of its shares such written information with respect to said Fund as Distributor may reasonably request. Each Fund represents and warrants that such information, when authenticated by the signature of one of its officers, shall be true and correct. Each Fund shall also furnish to Distributor copies of its reports to its shareholders and such additional information regarding said Fund’s financial condition as Distributor may reasonably request. Any and all representations, statements and solicitations respecting a Fund’s shares made in advertisements, sales literature, and in any other manner whatsoever shall be limited to and conform in all respects to the information provided hereunder.
c.    Regulatory Compliance. Each Fund shall furnish to Distributor copies of its current form of prospectus, as filed with the SEC, in such quantity as Distributor may reasonably request from time to time, and authorize Distributor to use the prospectus in connection with the sale of such Fund’s shares. All such sales shall be initiated by offer of, and conducted in accordance with, such prospectus and all of the provisions of the Securities Act of 1933, the 1940 Act and all the rules and regulations promulgated thereunder. Distributor shall furnish applicable federal and state regulatory authorities with any information or reports related to its services under this Agreement that such authorities may lawfully request in order to ascertain whether the Funds’ operations are being conducted in a manner consistent with any applicable law or regulations.
d.    Acceptance. All orders for the purchase of its shares are subject to acceptance by each Fund.

American Century Investment Trust
4500 Main Street
Kansas City, Missouri 64111


Ladies and Gentlemen:

I have acted as counsel to American Century Investment Trust, a business trust formed under the laws of the Commonwealth of Massachusetts (the “Trust”), in connection with Post-Effective Amendment No. 81 (the “PEA”) to the Trust’s Registration Statement on Form N-1A (File Nos. 033-65170, 811-07822), registering an indefinite number of shares of beneficial interest of the Trust under the Securities Act of 1933, as amended (the “1933 Act”), and under the Investment Company Act of 1940, as amended (the “1940 Act”). As used in this letter, the term “Shares” refers to the series, and classes of such series, of shares of beneficial ownership of the Trust indicated on Schedule A hereto.

In connection with rendering the opinions set forth below, I have examined the PEA; the Trust’s Amended and Restated Agreement and Declaration of Trust and the current Bylaws, as reflected in the corporate records of the Trust; resolutions of the Board of Trustees of the Trust relating to the authorization and issuance of the Shares; and such other documents as I deemed relevant. In conducting my examination, I have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity, accuracy and completeness of documents purporting to be originals and the conformity to originals of any copies of documents. I have not independently established any facts represented in the documents so relied on.

I am a member of the Bar of the State of Missouri. The opinions expressed in this letter are based on the facts in existence and the laws in effect on the date hereof and are limited to the laws (other than the conflict of law rules) of the Commonwealth of Massachusetts that in my experience are normally applicable to the issuance of shares by entities such as the Trust. I express no opinion with respect to any other laws.

Based upon and subject to the foregoing and the qualifications set forth below, it is my opinion that:

1. The issuance of the Shares has been duly authorized by the Trust.

2. When issued and paid for upon the terms provided in the PEA, and assuming the continued valid existence of the Trust under the laws of the Commonwealth of Massachusetts, the Shares will be legally issued, fully paid and non-assessable. However, I note that shareholders of the Trust may, under certain circumstances, be held personally liable for the obligations of the Trust.





For the record, it should be stated that I am an employee of American Century Services, LLC, an affiliate of the Trust’s investment advisor.

I hereby consent to the use of this opinion as an exhibit to the PEA. I assume no obligation to advise you of any changes in the foregoing subsequent to the effectiveness of the PEA. In giving my consent I do not thereby admit that I am in the category of persons whose consent is required under Section 7 of the 1933 Act or the rules and regulations of the SEC thereunder. The opinions expressed herein are matters of professional judgment and are not a guarantee of result.

Very truly yours,
/s/ Ashley Bergus

OF
AMERICAN CENTURY INVESTMENT TRUST

    WHEREAS, the above-named trust (the “Issuer”) is an open-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”);

    WHEREAS, the units of interest of the Issuer are currently divided into various classes of separate series of shares;

    WHEREAS, Rule 18f-3 requires that the Board of Trustees of the Issuer (the “Board”), adopt a written plan (a “Multiple Class Plan”) setting forth (1) the specific arrangement for shareholder services and the distribution of securities for each class, (2) the allocation of expenses for each class, and (3) any related conversion features or exchange privileges;

    WHEREAS, the Issuer has offered multiple classes of certain series of the Issuer’s shares pursuant to Rule 18f-3 under the 1940 Act since the Board initially adopted the original Multiple Class Plan;

    WHEREAS, the Board, including a majority of those Trustees who are not “interested persons” as defined in the 1940 Act (“Independent Trustees”), has determined this Amended and Restated Multiple Class Plan (this “Plan”), adopted pursuant to Rule 18f-3 under the 1940 Act, is in the best interests of the shareholders of each class individually and the Issuer as a whole;

    WHEREAS, the Issuer has added a new G Class to the series of shares titled Diversified Bond Fund and High Income Fund; and

    WHEREAS, the Issuer desires to amend this Plan to reflect the aforementioned change and there are no other changes to this Plan.

    NOW, THEREFORE, the Issuer hereby amends and restates, on behalf of the Funds (as defined in Section 2a below), this Plan, in accordance with Rule 18f-3 under the 1940 Act on the following terms and conditions:

Section 1.    Establishment of Plan

As required by Rule 18f-3 under the 1940 Act, this Plan describes the multiple class system for certain series of shares of the Issuer, including the separate class arrangements for shareholder services and/or distribution of shares, the method for allocating expenses to classes and any related conversion features or exchange privileges applicable to the classes. Upon the initial effective date of this Plan, the Issuer began offering multiple classes of shares of its units of interest, as described herein, pursuant to Rule 18f-3 and this Plan.




Section 2.    Features of the Classes

a.    Division into Classes.

The classes that each Fund is authorized to issue pursuant to this Plan are set forth in SCHEDULE A. Shares of each class of a Fund shall represent an equal pro rata interest in such Fund, and generally, shall have identical voting, dividend, liquidation and other rights, preferences, powers, restrictions, limitations, qualifications, and terms and conditions, except that each class of shares shall: (A) have a different designation; (B) bear any Class Expenses, as defined in Section 3d(3) below; (C) have exclusive voting rights on any matter submitted to shareholders that relates solely to its service arrangement; and (D) have separate voting rights on any matter submitted to shareholders in which the interests of one class differ from the interests of any other class.

Section 3.    Allocation of Income and Expenses

a.    Daily Dividend Funds. Funds that declare distributions of net investment income daily to maintain the same net asset value per share in each class (“Daily Dividend Funds”) will allocate gross income and expenses (other than Class Expenses, as defined below) to each class on the basis of “relative net assets (settled shares)”. Realized and unrealized capital gains and losses will be allocated to each class on the basis of relative net assets. “Relative net assets (settled shares),” for this purpose, are net assets valued in accordance with generally accepted accounting principles but excluding the value of subscriptions receivable, in relation to the net assets of the particular Daily Dividend Fund. Expenses to be so allocated include Issuer Expenses and Fund Expenses, each as defined below.

b.    Non-Daily Dividend Funds. The gross income, realized and unrealized capital gains and losses and expenses (other than Class Expenses) of each Fund, other than the Daily Dividend Funds, shall be allocated to each class on the basis of its net asset value relative to the net asset value of the Fund. Expenses to be so allocated also include Issuer Expenses and Fund Expenses.

c.    Apportionment of Certain Expenses. Expenses of a Fund shall be apportioned to each class of shares depending on the nature of the expense item. Issuer Expenses and Fund Expenses will be allocated among the classes of shares pro rata based on their relative net asset values in relation to the net asset value of all outstanding shares in the Fund. Approved Class Expenses shall be allocated to the particular class to which they are attributable. In addition, certain expenses may be allocated differently if their method of imposition changes. Thus, if a Class Expense can no longer be attributed to a class, it shall be charged to a Fund for allocation among classes, as determined by the Advisor.

6




d.    Definitions.

(1)    Issuer Expenses. “Issuer Expenses” include expenses of the Issuer that are not attributable to a particular Fund or class of a Fund. Issuer Expenses include fees and expenses of those Independent Trustees, including counsel fees for the Independent Trustees, and certain extraordinary expenses of the Issuer that are not attributable to a particular Fund or class of a Fund.

(2)    Fund Expenses. “Fund Expenses” include expenses of the Issuer that are attributable to a particular fund but are not attributable to a particular class of the Fund. Fund Expenses include (i) interest expenses, (ii) taxes, (iii) brokerage expenses, and (iv) certain extraordinary expenses of a Fund that are not attributable to a particular class of a Fund.

(3)    Class Expenses. “Class Expenses” are expenses that are attributable to a particular class of a Fund and shall be limited to: (i) applicable unified fee; (ii) payments made pursuant to the 12b-1 Plan of each applicable Class; and (iii) certain extraordinary expenses of an Issuer or Fund that are attributable to a particular class of a Fund.

(4)    Extraordinary Expenses. “Extraordinary expenses” shall be allocated as an Issuer Expense, a Fund Expense or a Class Expense in such manner and utilizing such methodology as the Advisor shall reasonably determine, which determination shall be subject to ratification or approval of the Board and shall be consistent with applicable legal principles and requirements under the 1940 Act and the Internal Revenue Code, as amended. The Advisor shall report to the Board quarterly regarding those extraordinary expenses that have been allocated as Class Expenses. Any such allocations shall be reviewed by, and subject to the approval of, the Board.

Section 4.    Exchange Privileges

Subject to the restrictions and conditions set forth in the Funds’ prospectuses, shareholders of each class of shares may exchange shares of one class of a Fund for shares of the same class of another Fund, provided that the amount to be exchanged meets the applicable minimum investment requirements and the shares to be acquired in the exchange are qualified for sale in the shareholder’s state of residence.

Section 5.    Conversion Features

Except as set forth in Section 2(d)(3), conversions from one class of a Fund’s shares into another class of shares are not permitted; provided, however, that if a shareholder of a particular class is no longer eligible to own shares of that class, upon prior notice to such shareholder, those shares will be converted to shares of the same Fund but of another class in which such shareholder is eligible to invest. Similarly, if a shareholder becomes eligible to invest in shares of another class that has lower expenses than the class in which such
7



shareholder is invested, such shareholder may be eligible to convert into shares of the same Fund but of the class with the lower expenses.

Section 6.    Quarterly and Annual Reports

The Board shall receive quarterly and annual reports concerning all allocated Class Expenses and distribution and servicing expenditures complying with paragraph (b)(3)(ii) of Rule 12b-1, as it may be amended from time to time. In the reports, only expenditures properly attributable to the sale or servicing of a particular class of shares will be used to justify any distribution or servicing fee or other expenses charged to that class. Expenditures not related to the sale or servicing of a particular class shall not be presented to the Board to justify any fee attributable to that class. The reports, including the allocations upon which they are based, shall be subject to the review and approval of the Independent Trustees of the Issuer who have no direct or indirect financial interest in the operation of this Plan in the exercise of their fiduciary duties.

Section 7.    Waiver or Reimbursement of Expenses

Expenses may be waived or reimbursed by any adviser to the Issuer, by the Issuer’s underwriter or by any other provider of services to the Issuer without the prior approval of the Board, provided that the fee is waived or reimbursed to all shares of a particular Fund in proportion to their relative average daily net asset values.

Upon receipt of approval by votes of a majority of both (a) the Board and (b) the Independent Trustees, this Plan which was originally effective August 1, 1997, shall be amended and restated as of May 19, 2022.

Section 9.    Material Modifications

This Plan may not be amended to modify materially its terms unless such amendment is approved a majority of both (a) the Board and (b) the Independent Trustees; provided; however; that a new Fund may be added, or an existing Fund deleted, by the Issuer upon approval by the Issuer’s Board by executing an amendment with a revised Schedule A to this Plan.
