The Trustees of MassMutual Premier Funds (the “Trustees”) are distributing this Information Statement in connection with the approval of an amendment (the “Amendment”) to the Amended and Restated Rule 12b-1 Plan for the Funds (the Funds’ “New Rule 12b-1 Plan”) which affects the Funds’ outstanding Class N shares (to become known as Class R3 shares on April 1, 2014). This Information Statement explains why the Trustees approved the Amendment and describes generally the terms of the New Rule 12b-1 Plan and the Amendment. Massachusetts Mutual Life Insurance Company (“MassMutual”) in its capacity as the sole shareholder of each Fund’s Class N shares (the “Sole Shareholder”) will approve the Amendment. This Information Statement is being delivered to shareholders of record as of March 4, 2014 on or about March 18, 2014.

As required by federal securities laws, the Funds are distributing this Information Statement solely for your information in connection with action to be taken by the Sole Shareholder. The Sole Shareholder anticipates approving the Amendment by written consent on the date that is 20 days following the date of this Information Statement, or as soon thereafter as practicable. WE ARE NOT ASKING YOU FOR A PROXY, AND YOU ARE REQUESTED NOT TO SEND US A PROXY.

Approval of New Rule 12b-1 Plan and Amendment

At a meeting of the Trustees held on February 13, 2014, the Trustees approved the New Rule 12b-1 Plan and at the same time recommended that the Amendment be approved by shareholders. The New Rule 12b-1 Plan, except for the Amendment, is not materially different from the existing Rule 12b-1 Plan for the Funds, which was adopted for Class N shares on June 24, 2004 (December 2, 2004 for the Main Street Fund, Capital Appreciation Fund, and Global Fund, and September 22, 2005 for the Focused International Fund). The New Rule 12b-1 Plan continues to allow for the payment of up to .50% of the average daily net assets attributable to Class R3 shares of each Fund in accordance with Rule 12b-1 under the Investment Company Act of 1940, as amended (the “1940 Act”), to the Funds’ distributor, MML Distributors, LLC.

The New Rule 12b-1 Plan contains a provision (which was carried over from the existing Rule 12b-1 Plan) limiting the purposes for which payments under the New Rule 12b-1 Plan may be paid. Those limits are not required by applicable law, and may have the effect of restricting the benefits of the New Rule 12b-1 Plan. Specifically, the New Rule 12b-1 Plan provides that, of the 0.50% payable under the New Rule 12b-1 Plan in respect of a Fund’s Class R3 shares, up to 0.25% may be paid in respect of any activities or expenses primarily intended to result in the sale of Class R3 shares, and up to 0.25% may be paid in respect of shareholder services provided to investors in Class R3 shares. The Amendment will remove this limitation for Class R3 shares and thereby allow the Funds’ Class R3 shares simply to pay up to .50% of each Fund’s average daily net assets attributable to Class R3 shares under the New Rule 12b-1 Plan for any legitimate purpose.

In coming to this recommendation, the Trustees, including the independent Trustees voting separately, unanimously determined, in the exercise of their reasonable business judgment and in light of their fiduciary duties under state law and Sections 36(a) and (b) of the 1940 Act, that there is a reasonable likelihood the New Rule 12b-1 Plan, as amended, will benefit shareholders of Class R3 shares of each Fund. In this regard, the Trustees, who were represented by independent legal counsel throughout, considered the views of the Funds’ management that the maximum amount payable under the New Rule 12b-1 Plan would not increase as a result of the Amendment; that substantially all amounts payable under the New Rule 12b-1 Plan, as amended, were expected to continue to be used to compensate or reimburse financial intermediaries (whether or not affiliated with MassMutual) for distribution and shareholder servicing; and that the removal of the internal limitations from the New Rule 12b-1 Plan would increase flexibility to respond to developments and changes in the markets for the distribution of mutual fund shares and servicing of shareholder accounts. Prior to a vote being taken to approve the New Rule 12b-1 Plan, the independent Trustees met separately in executive session with their independent legal counsel to discuss the New Rule 12b-1 Plan’s appropriateness.

MassMutual, as the sole shareholder of each Fund’s Class N shares, intends to approve the Amendment by written consent.

Description of the New Rule 12b-1 Plan, as amended

Appendix A to this Information Statement contains the New Rule 12b-1 Plan, as amended. While the next several paragraphs briefly summarize the material provisions of the New Rule 12b-1 Plan, you should read Appendix A for a complete understanding of the New Rule 12b-1 Plan.

The New Rule 12b-1 Plan essentially provides that each class of shares of a Fund may pay fees pursuant to the New Rule 12b-1 Plan at annual rates as may be determined by the Board of Trustees, which rates shall not exceed the rates set forth on Exhibit A to the New Rule 12b- Plan. The New Rule 12b-1 Plan may be amended at any time by the Board of Trustees, provided that (a) any amendment to increase materially the rate at which payments may be made by a class of shares of a Fund under the New Rule 12b-1 Plan shall be effective only upon approval by a vote of a majority of the outstanding voting securities (as such term is defined in the 1940 Act) of that class of shares, and (b) any material amendment of this Plan shall be effective only upon approval by a vote of both a majority of the Board of Trustees and a majority of the independent Trustees, cast in person at a meeting called for the purpose of voting on such amendment. The New Rule 12b-1 Plan may be terminated at any time with respect to any class of shares of a Fund, without payment of any penalty, by vote of a majority of the independent Trustees, or by vote of a majority of the outstanding voting securities (as such term is defined in the 1940 Act) of that class of shares. While the New Rule 12b-1 Plan is in effect, the Funds’ principal underwriter shall provide to the Trustees, and the Trustees shall review, at least quarterly, a written report of the amounts expended pursuant to the New Rule 12b-1 Plan and the purposes for which such expenditures were made.

During the fiscal year ended September 30, 2013, Class N shares of the Short-Duration Bond Fund paid $5,352 in 12b-1 fees, Class N shares of the Inflation-Protected and Income Fund paid $6,464 in 12b-1 fees, Class N shares of the Core Bond Fund paid $8,858 in 12b-1 fees, Class N shares of the High Yield Fund paid $3,086 in 12b-1 fees, Class N shares of the Value Fund paid $404 in 12b-1 fees, Class N shares of the Disciplined Value Fund paid $704 in 12b-1 fees, Class N shares of the Main Street Fund paid $396 in 12b-1 fees, Class N shares of the Capital Appreciation Fund paid $732 in 12b-1 fees, Class N shares of the Global Fund paid $5,452 in 12b-1 fees, and Class N shares of the Focused International Fund paid $4,908 in 12b-1 fees.
