1940, as amended (the "1940 Act");

     WHEREAS,  the common stock of the Issuer is currently  allocated to various

"interested persons" as defined in the 1940 Act ("Independent  Directors"),  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.


                                       1


     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

     voting rights on any matter  submitted to shareholders  that relates solely

     from the interests of any other class.

     current Investor Class prospectus or prospectus supplement.  The R Class is

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   Directors,
     including  counsel  fees  for  the  Independent


                                       5


     Directors,  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


                                       6


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  Directors 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 Directors, 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
Directors;  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.
