RULE 18f-3 PLAN

Effective March 2, 2009

Amended September 11, 2024*

NOW, THEREFORE, the Trust, wishing to be governed by Rule 18f-3 under the 1940 Act, hereby adopts this Rule 18f-3 Plan as follows:

1. Each class of shares of a series will represent interests in the same portfolio of investments of such series of the Trust, and be identical in all respects to each other class of that series, except as set forth below. The only differences among the various classes of shares of the series of the Trust will relate solely to (a) different distribution or service fee payments associated with any Rule 12b-1 Plan for a particular class of shares and any other costs relating to implementing or amending such Plan (including obtaining shareholder approval of such Plan or any amendment thereto), which will be borne solely by shareholders of such class; and (b) different administrative service fees associated with any Administrative Services Plan; (c) different dedicated distribution channels; and (d) different Class Expenses, which will be limited to the following expenses as determined by the Trustees to be attributable to a specific class of shares: (i) transfer agency fees identified as being attributable to a specific class; (ii) printing and postage expenses related to preparing and distributing materials such as shareholder reports, prospectuses, and proxy statements to current shareholders of a specific class; (iii) Blue Sky notification and/or filing fees incurred by a class of shares; (iv) SEC registration fees incurred by a class; (v) expenses of administrative personnel and services as required to support the shareholders of a specific class; (vi) litigation or other legal expenses and audit or other accounting expenses relating solely to one class; (vii) Trustee fees or expenses incurred as a result of issues relating to one class; and (viii) shareholder meeting costs that relate to a specific class; (d) the voting rights related to any 12b-1 Plan affecting a specific class of shares or related to any other matter submitted to shareholders in which the interests of a Class differ from the interests of any other Class; (e) conversion features; (f) exchange privileges; and (g) class names or designations. Any additional incremental expenses not specifically identified above that are subsequently identified and determined to be properly applied to one class of shares of a series of the Trust shall be so applied upon approval by a majority of the Trustees of the Trust, including a majority of the Trustees who are not interested persons of the Trust.

2. Under the Multiple Class Distribution System, certain expenses may be attributable to the Trust, but not to a particular series or class thereof. All such expenses will be allocated among series based upon the relative aggregate net assets of such series. Expenses that are attributable to a particular series, but not to a particular class thereof, and income, realized gains and losses, and unrealized appreciation and depreciation will be allocated to each class based on its net asset value relative to the net asset value of the series if such series does not pay daily dividends and if the series does pay daily dividends on the basis of the settled shares method (as described in Rule 18f-3(c)(iii)). Notwithstanding the foregoing, the principal underwriter, the investment adviser or other provider of services to the Trust may waive or reimburse the expenses of a specific class or classes to the extent permitted under Rule 18f-3 under the 1940 Act and pursuant to any applicable ruling, procedure or regulation of the Internal Revenue Service.

RULE 18f-3 PLAN

Effective March 2, 2009

Amended September 11, 2024*

A class of shares may be permitted to bear expenses that are directly attributable to such class including: (a) any distribution/service fees associated with any Rule 12b-1 Plan for a particular class and any other costs relating to implementing or amending such Plan (including obtaining shareholder approval of such plan or any amendment thereto); (b) any administrative services fees associated with any administrative services plan for a particular class and any other costs relating to implementing or amending such plan (including obtaining shareholder approval of such plan or any amendment thereto) attributable to such class; and (c) any Class Expenses determined by the Trustees to be attributable to such class.

3. To the extent exchanges are permitted, shares of any class of the Trust will be exchangeable with shares of the same class of another series of the Trust, or with money market fund shares of the Trust as described in the applicable prospectus. Exchanges will comply with all applicable provisions of Rule 11a-3 under the 1940 Act.

4. Dividends and distributions paid by a series of the Trust as to each class of its shares, to the extent any dividends or distributions are paid, will be calculated in the same manner, at the same time, on the same day, and will be in the same amount for each such class, except that any distribution/service fees, administrative services fees, and Class Expenses allocated to a class will be borne exclusively by that class and will be taken into account in determining the amount of dividends and distributions paid with respect to that class.

5. Any distribution arrangement of the Trust, including distribution fees and front-end and deferred sales loads, will comply with Section 2341 of the Rules of the Financial Industry Regulatory Authority, Inc.

6. The initial adoption of, and all material amendments, to this 18f-3 Plan must be approved by a majority of the members of the Trust’s Trustees, including a majority of the Board members who are not “interested persons” (as defined in the 1940 Act) of the Trust.

7. Prior to the initial adoption of, and any material amendments to, this 18f-3 Plan, the Trust’s Trustees shall request and evaluate, and any agreement relating to a class arrangement shall require the parties thereto to furnish, such information as may be reasonably necessary to evaluate the 18f-3 Plan.
