E. Methodology for Allocating Expenses Between Classes

Expenses of a Portfolio are apportioned to each class of shares depending upon the nature of the expense item.

1. General Expenses

General Expenses are expenses that are attributable to both classes of shares and are allocated between the classes of shares based on the relative net asset values of their respective outstanding shares. General Expenses include advisory fees payable to the investment adviser under the investment advisory agreement and other expenses such as custody and professional fees.

2. Class-Specific Expenses

Class-Specific Expenses are expenses that are attributable to a specific class of shares and are allocated to the class of shares to which they relate. Such expenses include shareholder servicing expenses. Class-specific expenses that are based on a percentage of average daily net assets are calculated by multiplying the appropriate daily rate by the value of the outstanding shares of the respective class. Other class-specific expenses, which may include printing, postage, share certificates and other charges, are calculated based upon daily accrual rates furnished by the administrator which are based upon estimates of such expenses for the year.
