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.

               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.

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.

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.

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 January 1, 2008.
