                    AMERICAN CENTURY INTERNATIONAL BOND FUNDS


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

     WHEREAS, the common stock of the Issuer is currently allocated to 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 that 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;

     NOW, THEREFORE, the Issuer hereby adopts, 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 elects to offer multiple classes of shares of its
capital stock, as described herein, pursuant to Rule 18f-3 and this Plan.

SECTION 2.  FEATURES OF THE CLASSES

a.   DIVISION INTO CLASSES. Each series of shares of the Issuers identified in
     SCHEDULE A attached hereto, and each series of shares of any Issuer
     subsequently added to this Plan (collectively, the "Funds"), may offer one
     or more of the following classes of shares: Investor Class, Institutional
     Class, Advisor Class, A Class, B Class, C Class and R Class. 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.

          agreement (the "Management Agreement") with either American Century

          the Fund's current Investor Class prospectus or prospectus supplement.

          (2) Institutional Class Unified Fee. For each Fund listed on SCHEDULE

          intermediaries.

          (4) A Class Unified Fee. For each Fund listed on SCHEDULE A as being

          corresponding Investor Class of such Fund, as described in the Fund's
          current Investor Class prospectus or prospectus supplement. The A
          Class is intended to be sold to and through broker-dealers, banks and
          other financial intermediaries.

          (5) B Class Unified Fee. For each Fund listed on SCHEDULE A as being
          authorized to issue B Class shares, the Management Agreement provides

          corresponding Investor Class of such Fund, as described in the Fund's



                                       2



          current Investor Class prospectus or prospectus supplement. The B
          Class is intended to be sold to and through broker-dealers, banks and
          other financial intermediaries.

          (6) C Class Unified Fee. For each Fund listed on SCHEDULE A as being
          authorized to issue C Class shares, the Management Agreement provides

          corresponding Investor Class of such Fund, as described in the Fund's
          current Investor Class prospectus or prospectus supplement. The C
          Class is intended to be sold to and through broker-dealers, banks and
          other financial intermediaries.

          (7) R Class Unified Fee. For each Fund listed on SCHEDULE A as being

          for a unified fee equal to the existing unified fee in place for the
          corresponding Investor Class of such Fund, as described in the Fund's
          current Investor Class prospectus or prospectus supplement. The R
          Class is intended to be sold to employer-sponsored retirement plans
          (including participant directed plans), insurance companies,
          broker-dealers, banks and other financial intermediaries.

          prospectus.

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.

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


                                       5



     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 may (i) exchange shares of one class of a Fund for shares of the
same class of another Fund, (ii) exchange Investor Class shares for shares of
any fund within the American Century family of funds that only offers a single
class of shares (a "Single Class Fund"), and (iii) exchange shares of any Single
Class Fund for Investor Class shares 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
stockholder's state of residence.

SECTION 5.  CONVERSION FEATURES

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 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


                                       6



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.

SECTION 8.  EFFECTIVENESS OF PLAN

Upon receipt of approval by votes of a majority of both (a) the Board and (b)
the Independent Trustees, this Plan shall become effective September 4, 2007.

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 by the Issuer upon
approval by that Issuer's Board by executing a new Schedule A to this Plan.

     IN WITNESS WHEREOF, the Issuer has adopted this Multiple Class Plan as of
September 4, 2007.
