Dear Shareholder:

We cordially invite you to attend a Special Meeting of Shareholders of Eaton Vance Emerging Markets Fund (the “EM Fund”) on August 13, 2010 to consider a proposal to approve an Agreement and Plan of Reorganization to convert shares of the EM Fund into Class A shares of Eaton Vance Structured Emerging Markets Fund (the “SEM Fund”) (the “Reorganization”).

The investment objective for each Fund is to provide long term capital appreciation. The investment policies of each Fund are substantially similar. The enclosed combined Proxy Statement and Prospectus (“Proxy Statement/Prospectus”) describes the Reorganization in detail. We ask you to read the enclosed information carefully and to submit your vote promptly.

After consideration and recommendation by Eaton Vance Management, the Board of Trustees of the EM Fund has determined that it is in the best interests of the EM Fund if the EM Fund is merged into the SEM Fund. We believe that you would benefit from the Reorganization because you would become shareholders of a larger, more diversified fund with a lower expense ratio.

We realize that most shareholders will not be able to attend the meeting and vote their shares in person. However, the EM Fund does need your vote. You can vote by mail or by telephone, as explained in the enclosed material. If you later decide to attend the meeting, you may revoke your proxy and vote your shares in person. By voting promptly, you can help the EM Fund avoid the expense of additional mailings.

If you would like additional information concerning this proposal, please call one of our service representatives at 1-800-262-1122 Monday through Friday, 8:00 a.m. to 6:00 p.m. Eastern time. Your participation in this vote is extremely important.

SUMMARY

The following is a summary of certain information contained in or incorporated by reference in this Proxy Statement/Prospectus. This summary is not intended to be a complete statement of all material features of the proposed Reorganization and is qualified in its entirety by reference to the full text of this Proxy Statement/ Prospectus, the Plan and the other documents referred to herein.

Proposed Transaction. The Trustees of the SI Trust have approved the Plan, which provides for the transfer of all of the assets of the EM Fund to the SEM Fund in exchange for the issuance of Class A shares of SEM Fund and the assumption of all of the EM Fund’s liabilities by the SEM Fund at a closing to be held as soon as practicable following approval of the Reorganization by shareholders of the EM Fund at the Special Meeting, or any adjournments or postponements thereof, and the satisfaction of all the other conditions to the Reorganization (the “Closing”). The Plan is attached hereto as Appendix A. The value of each shareholder’s account with the SEM Fund immediately after the Reorganization will be the same as the value of such shareholder’s account with the EM Fund immediately prior to the Reorganization. Following the transfer, Class A shares of SEM Fund will be distributed to shareholders of the EM Fund and the EM Fu nd will be terminated. As a result of the Reorganization, each shareholder of the EM Fund will receive full and fractional Class A shares of SEM Fund equal in value at the close of regular trading on the New York Stock Exchange on the Closing date to the value of such shareholder’s shares of the EM Fund. At or prior to the Closing, the EM Fund shall declare a dividend or dividends which, together with all previous such dividends, shall have the effect of distributing to its shareholders all of its investment company taxable income, its net tax-exempt interest income, and all of its net capital gains, if any, realized for the taxable year ending at the Closing. The Trustees, including the Trustees who are not “interested persons” of the SI Trust as defined in the Investment Company Act of 1940, as amended (the “1940 Act”) (“Independent Trustees”), have determined that the interests of existing shareholders of EM Fund will not be diluted as a result of the transaction contemp lated by the Reorganization and that the Reorganization is in the best interests of the EM Fund. The Board of Trustees of MF Trust (including the Independent Trustees of MF Trust) has also approved the Plan on behalf of the SEM Fund.

Background for the Proposed Transaction. In approving the Plan, the Board of Trustees of SI Trust considered a number of factors, including the proposed terms of the Reorganization. The Trustees considered similarities between the Funds’ investment objective and policies and, among other things, the lower total operating expenses that would be realized by the EM Fund’s shareholders and the expected tax-free nature of the Reorganization. Moreover, the Trustees considered that shareholders of EM Fund would benefit from a larger, more diversified fund with increased investment opportunities and flexibility as a result of the Reorganization.

The Board of Trustees of the SI Trust believes that the proposed Reorganization is in the best interests of EM Fund and has recommended that the EM Fund’s shareholders vote for the Reorganization.

Objectives, Restrictions and Policies. The EM Fund and SEM Fund have substantially similar investment objectives and policies. In addition, there are no material differences between the Fund’s fundamental and non-fundamental investment restrictions.

The SEM Fund invests directly in securities. The EM Fund is a “feeder” fund investing in a “master” fund. In a master-feeder structure, the feeder fund invests all or substantially all of its assets in a single master fund, which directly owns a portfolio of securities. The master fund in which EM Fund invests its assets, Emerging Markets Portfolio, is sometimes referred to herein as the “Portfolio”.

Fund Fees, Expenses and Services. SEM Fund (total net assets of approximately $1.31 billion as of March 31, 2010) is significantly larger than EM Fund (total net assets of approximately $58.4 million as of March 31, 2010). As described below, SEM Fund has a lower total expense ratio than EM Fund. As the result of the Reorganization, the EM Fund’s shareholders are expected to benefit from the SEM Fund’s lower expense ratio.

EM Fund offers Classes A and B shares, while SEM Fund offers Class A, C and I shares. As a result of the Reorganization, shareholders of each class of shares of EM Fund would receive Class A shares of the SEM Fund. The privileges and services associated with the Class A shares of each Fund are identical. Class B shares of EM Fund differ in that they are subject to a 1.00% distribution fee and a contingent deferred sales charge (“CDSC”) (while Class A shares of each Fund have a front-end sales charge). Class B shares of EM Fund have a conversion feature, whereby they convert to the lower cost Class A shares eight years after their initial purchase. Former Class B shareholders of the EM Fund receiving Class A shares of the SEM Fund as a result of the Reorganization will have any remaining CDSC waived, but such shareholders will have a Class A front-end sales charge for additional purchases of SEM Fund. It is beneficial to Class B shareholders of EM Fund to be exchanged into the lower cost Class A shares of SEM Fund. Class C and Class I shares of SEM Fund will not be offered as part of the Reorganization.

Distribution Arrangements. Shares of each Fund are sold on a continuous basis by Eaton Vance Distributors, Inc. (“EVD”), the Funds’ principal underwriter. Class A shares of each Fund are sold at net asset value per share plus a front-end sales charge. Class A shares of EM Fund pay a distribution fee to the principal underwriter of 0.50% annually of average daily net assets on shares outstanding for less than twelve months and a distribution fee of 0.25% annually of average daily net assets on shares outstanding for more than twelve months. Class A shares of EM Fund also pay service fees to the principal underwriter equal to 0.25% of average daily net assets annually with respect to shares that have remained outstanding for more than one year. Class B shares of EM Fund are subject to distribution and service fees equal to 1.00% annually of average daily net assets. Class A shares of SEM Fund pay distribution and service fees equal to 0.25% of average daily net assets annually. As a result of the Reorganization, shareholders of each class of shares of EM Fund would receive Class A shares of the SEM Fund.

Redemption Procedures and Exchange Privileges. The EM Fund and the SEM Fund offer the same redemption features pursuant to which proceeds of a redemption are remitted by wire or check after receipt of proper documents including signature guarantees. The Class A shares of each Fund have the same exchange privileges.

Tax Consequences. The EM Fund expects to obtain an opinion of counsel that the Reorganization will be tax-free for federal income tax purposes. As such, the EM Fund’s shareholders will not recognize a taxable gain or loss on the receipt of shares of the SEM Fund in liquidation of their interests in EM Fund. Their tax basis in SEM Fund shares received in the Reorganization will be the same as their tax basis in the EM Fund shares, and the tax holding period will be the same.

FUND EXPENSES

Expenses shown are those for the year ended March 31, 2010 and on a pro forma basis giving effect to the Reorganization as of such date.

(1)	Expenses of the EM Fund in the table above and the example below reflect the expenses of the EM Fund and Emerging Markets Portfolio.
(2)	EM Fund: The Adviser and the Administrator have agreed to reduce the Total Annual Fund Operating Expenses by 0.05% annually. This agreement is contractual in nature and may not be terminated without shareholder approval. This reduction relates to ordinary operating expenses only.
(3)	EM Fund: Effective April 27, 2009, the Adviser and the Administrator have agreed to further reduce the Total Annual Fund Operating Expenses by an additional 0.10% annually through April 30, 2011. This reduction relates to ordinary operating expenses only.
(4)	SEM Fund: Investment adviser, sub-adviser and administrator have agreed to limit the Total Annual Fund Operating Expenses (other than Acquired Fund Fees and Expenses allocated from unaffiliated investment companies) of Class A to 1.60%. This expense limitation will continue through February 28, 2011. Thereafter, the expense limitation may be changed or terminated at any time. The expense limitation relates to ordinary operating expenses only and amounts reimbursed may be subject to recoupment.

Example. This Example is intended to help you compare the cost of investing in the Pro Forma Combined Fund after the Reorganization with the cost of investing in the Funds without the Reorganization. The Example assumes that you invest $10,000 in a Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the operating expenses remain the same as stated in the Fund Fees and Expenses table above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:


	Expenses with Redemption				Expenses without Redemption
	1 Year	3 Year	5 Year	10 Years	1 Year	3 Year	5 Year	10 Years

EM Fund
Class A shares	$ 814	$1,326	$1,864	$3,325	$ 814	$1,326	$1,864	$3,325
Class B shares	$ 803	$1,345	$1,813	$3,280	$ 313	$ 945	$1,613	$3,280

REASONS FOR THE REORGANIZATION

The Reorganization was proposed to the Board of Trustees of the SI Trust by Eaton Vance Management (“EVM” or “Eaton Vance”) in response to inquiries from the Trustees with respect to the investment performance, expense levels and decline in assets experienced by the Fund in recent years. In reaching the decision to recommend that the shareholders of the EM Fund vote to approve the Reorganization, the Trustees considered a number of factors, including factors identified by EVM in connection with its recommendation that the Trustees approve the Reorganization. The Trustees, including the Independent Trustees, concluded that the Reorganization would be in the best interests of the EM Fund and that the interests of existing shareholders would not be diluted as a consequence thereof. The factors considered by the Trustees include the following:


•	*Changes in Objectives, Restrictions and Policies.* The Funds have the same investment
	objectives and similar policies and restrictions. Each Fund invests 80% of its net assets in equity
	securities of


	companies located in emerging market countries. While EM Fund utilizes fundamental
	research in making investment decisions, SEM Fund employs quantitative investment techniques and
	analyses. EM Fund generally holds approximately 60 portfolio securities, while SEM Fund generally
	holds over 1,500 portfolio securities. The Funds’ fundamental and non-fundamental investment
	restrictions are substantially the same.

•	*Effect on Class Structure and Services.* EM Fund offers Class A and B shares, while SEM Fund
	offers Class A, C and I shares. As a result of the Reorganization, shareholders of each Class of
	shares of EM Fund would receive Class A shares of SEM Fund. The privileges and services
	associated with Class A shares of each Fund are identical. Class B shares of EM Fund differ from
	Class A shares in that they are subject to 1.00% distribution and service fees and also to a contingent
	deferred sales charge (while Class A shares of each Fund have a front-end sales charge). Class B
	shares of EM Fund have a conversion feature, whereby they convert to the lower cost Class A shares
	eight years after their initial purchase. Former Class B shareholders of the EM Fund will not be
	subject to a CDSC upon the redemption of the Class A shares they receive as a result of the
	Reorganization, but will have to pay a front-end sales charge on additional purchases of Class A
	shares of the SEM Fund (as described above in “Distribution Arrangements”). It is beneficial to Class
	B shareholders of EM Fund to be exchanged into the lower cost Class A shares of SEM Fund.

•	*Effect on Fund Fees and Expenses.* The annual management fees of SEM Fund are 0.25% lower
	than those of EM Fund. The annual advisory fee rate for EM Fund is 0.75% annually of average daily
	net assets less than $500 million, and at reduced rates on net assets of $500 million and above. The
	annual advisory fee rate for SEM Fund is 0.85% annually of average daily net assets less than $500
	million; 0.80% on assets from $500 million to $1 billion; 0.775% on assets from $1 billion to $2.5
	billion; and at reduced rates thereafter. In addition, EM Fund currently pays to EVM management
	fees equal to 0.25% and administrative fees equal to 0.25% annually on average daily net assets up
	to $500 million, and at reduced rates thereafter. EVM has contractually agreed to reduce total annual
	operating expenses of the EM Fund by 0.15%. For its services as administrator of SEM Fund, EVM
	receives 0.15% annually of average daily net assets.

	If the Reorganization is consummated, EVM estimates EM Fund will realize a significant reduction in
	other expenses. On a pro forma basis assuming the consummation of the Reorganization on March
	31, 2010, the total fund expenses payable by former EM Fund shareholders would decrease by
	approximately 90 basis points (or 0.90%) for Class A shareholders and by approximately 140 basis
	points (or 1.40%) for Class B shareholders after the Reorganization.

•	*Costs of the Reorganization.* EM Fund will bear the costs of the Reorganization, including legal,
	printing, mailing and solicitation costs. These costs are estimated at approximately $70,000.

•	*Tax Consequences.* EM Fund expects to receive an opinion from counsel that the Reorganization
	will be tax-free for federal income tax purposes. As such, EM Fund shareholders would not recognize
	a taxable gain or loss on the receipt of shares of SEM Fund in liquidation of their interest in EM Fund.
	Their tax basis in the SEM Fund shares received in the Reorganization would be the same as their
	tax basis in their EM Fund shares, and the tax holding period would be the same. SEM Fund’s tax
	basis for the assets received in the Reorganization would be the same as EM Fund’s basis
	immediately before the Reorganization, and SEM Fund’s tax holding period for those assets would
	include the EM Fund’s holding period. It is possible that the Reorganization would preclude utilization
	of approximately $300,000 in capital loss carryforwards of EM Fund. However, these carryforwards
	could be offset with capital gains realized by EM Fund prior to the Reorganization.

•	*Relative Performance.* The SEM total return for Class A shares for the applicable periods ended
	December 31, 2009, as described in “Performance Information” below, exceeded that of Class A
	shares of the EM Fund.


•	*No Dilution.* After the Reorganization, each former EM Fund shareholder will own shares of SEM
	Fund equal to the aggregate value of his or her EM Fund shares immediately prior to the
	Reorganization. Because shares of SEM Fund will be issued at the per share net asset value of the
	Fund in exchange for the assets of EM Fund, that, net of the liabilities of EM Fund assumed by SEM
	Fund, will equal the aggregate value of those shares, the net asset value per share of SEM Fund will
	be unchanged. Thus, the Reorganization will not result in any dilution to shareholders.

•	*Impact on EVM.* After the Reorganization, EVM will continue to serve as investment adviser and
	Parametric Portfolio Associates LLC (“Parametric”) as sub-adviser to SEM Fund. EVM and its
	affiliates will collect advisory, administrative and distribution and service fees on EM Fund assets
	acquired by SEM Fund pursuant to the Reorganization. In the case of advisory fees, EVM would
	collect fees on the EM Fund assets at the incremental advisory fee rates applicable to SEM Fund,
	currently 0.775% annually. EVM will no longer collect the management and administration fees and
	EVD will no longer collect the Class A 0.25% distribution fee from EM Fund. EVD receives a
	distribution fee of 0.50% annually of average daily net assets on EM Class A shares outstanding for
	less than twelve months, and 0.25% annually thereafter. EVD receives a distribution fee of 0.25%
	annually of average daily net assets on SEM Class A shares. At current asset levels, the
	Reorganization would result in approximately $70,000 in lost fee revenue annually to EVM and
	approximately $264,000 in increased fee revenue annually to Parametric. The Reorganization will
	result in a decrease in fee revenues payable annually to EM Fund’s investment adviser, Lloyd George
	Investment Management (Bermuda) Limited (“Lloyd George Management”), of approximately
	$374,000.

	In addition, because Class B shares of EM Fund will be exchanged for Class A shares of SEM Fund
	in the Reorganization, EVD will no longer receive distribution support payments from Lloyd George
	Management based on Class B shares of EM Fund of approximately $18,000 annually and will
	extinguish the remaining liability for distribution and service fees payable on EM Fund Class B shares
	of approximately $7,000.

	*Other Considerations.* It is likely that EM Fund will dispose of securities in advance of the
	Reorganization as is consistent with the treatment of the Reorganization as tax-free and, in that
	connection, it will realize capital gains. EVM believes that EM Fund has sufficient capital loss
	carryforwards to offset any such gain. EM Fund also will incur transaction costs in connection with
	such sales equal to approximately 50 basis points (or 0.50% of total net assets). EVM believes that
	the substantial benefits that will accrue to EM Fund shareholders as a result of the Reorganization
	(such as the estimated expense reduction of approximately 90 basis points (or 0.90%) for Class A
	shares and 140 basis points (or 1.40%) for Class B shares) outweigh any such costs.

The Board of Trustees of the SI Trust believes that the proposed Reorganization is in the best interest of the EM Fund and recommends that the EM Fund’s shareholders vote for the Reorganization.

INFORMATION ABOUT THE REORGANIZATION

At a meeting held on April 26, 2010, the Board of Trustees of the SI Trust approved the Plan in the form set forth as Appendix A to this Proxy Statement/Prospectus. The summary of the Plan is not intended to be a complete statement of all material features of the Plan and is qualified in its entirety by reference to the full text of the Plan attached hereto as Appendix A.

Agreement and Plan of Reorganization. The Plan provides that, at the Closing, the Trust shall transfer all of the assets of the EM Fund and assign all liabilities to SEM Fund, and SEM Fund shall acquire such assets and shall assume such liabilities upon delivery by SEM Fund to the EM Fund on the Closing date of Class A shares of SEM Fund (including, if applicable, fractional shares). The value of Class A shares issued to the EM Fund by SEM Fund will be the same as the value of Class A and Class B shares that the EM Fund has outstanding on the Closing date. The SEM Fund shares received by the EM Fund will be distributed to the EM Fund’s shareholders, and the EM Fund shareholders will receive shares of Class A of the SEM Fund equal in value to those of the EM Fund held by the shareholder.

SEM Fund will assume all liabilities, expenses, costs, charges and reserves of the EM Fund on the Closing date. At or prior to the Closing, the EM Fund shall declare (if any) a dividend or dividends which, together with all previous such dividends, shall have the effect of distributing to the EM Fund’s shareholders all of the EM Fund’s investment company taxable income, net tax-exempt interest income, and net capital gain, if any, realized (after reduction for any available capital loss carry-forwards) in all taxable years ending at or prior to the Closing.

At, or as soon as practicable after the Closing, the EM Fund shall liquidate and distribute pro rata to its shareholders of record as of the close of trading on the New York Stock Exchange on the Closing date the full and fractional SEM Fund Class A shares equal in value to the EM Fund’s shares exchanged. Such liquidation and distribution will be accomplished by the establishment of shareholder accounts on the share records of SEM Fund in the name of each shareholder of the EM Fund, representing the respective pro rata number of full and fractional SEM Fund Class A shares due such shareholder. All of SEM Fund’s future distributions attributable to the shares issued in the Reorganization will be paid to shareholders in cash or invested in additional shares of SEM Fund at the price in effect as described in the SEM Fund’s current prospectus on the respective payment dates in a ccordance with instructions previously given by the shareholder to the Fund’s transfer agent.

The consummation of the Plan is subject to the conditions set forth therein. Notwithstanding approval by shareholders of the EM Fund, the Plan may be terminated at any time prior to the consummation of the Reorganization without liability on the part of either party or its respective officers, trustees or shareholders, by either party on written notice to the other party if certain specified representations and warranties or conditions have not been performed or do not exist on or before December 31, 2010. The Plan may be amended by written agreement of its parties without approval of shareholders and a party may waive without shareholder approval any default by the other or any failure to satisfy any of the conditions to its obligations; provided, however, that following the Special Meeting, no such amendment or waiver may have the effect of changing the provision for determining the number of SEM Fund shares to be issued to the EM Fund’s shareholders to the detriment of such shareholders without their further approval.

Costs of the Reorganization. The EM Fund will bear the costs of the Reorganization, including legal, printing, mailing and solicitation costs. The costs of the Reorganization are estimated at approximately $70,000.

Description of SEM Fund Shares. Full and fractional Class A shares of SEM Fund will be distributed to the EM Fund’s shareholders in accordance with the procedures under the Plan as described above. Each SEM Fund Class A share will be fully paid, non-assessable when issued and transferable without restrictions and will have no preemptive or cumulative voting rights and have only such conversion or exchange rights as the Trustees may grant in their discretion.

Federal Income Tax Consequences. It is expected that the Reorganization will qualify as a tax-free transaction under Section 368(a) of the Internal Revenue Code, which is expected to be confirmed by the legal opinion of K&L Gates LLP at the Closing. Accordingly, shareholders of the EM Fund will not recognize any capital gain or loss and the EM Fund’s assets and capital loss carry-forwards should be transferred to SEM Fund without recognition of gain or loss.

It is possible, however, that the Reorganization may fail to satisfy all of the requirements necessary for tax-free treatment, in which event the transaction will nevertheless proceed on a taxable basis. In this event, the Reorganization will result in the recognition of gain or loss to the EM Fund’s shareholders depending upon their tax basis (generally, the original purchase price) for their EM Fund shares, which includes the amounts paid for shares issued in reinvested distributions, and the net asset value of shares of SEM Fund received in the Reorganization. Shareholders of the EM Fund would, in the event of a taxable transaction, receive a new tax basis in the shares they receive of SEM Fund (equal to their initial value) for calculation of gain or loss upon their ultimate disposition and would start a new holding period for such shares.

Shareholders should consult their tax advisers regarding the effect, if any, of the proposed Reorganization in light of their individual circumstances. Because the foregoing discussion relates only to the federal income tax consequences of the Reorganization, shareholders should also consult their tax advisers as to state and local tax consequences, if any.

Capitalization. The following table (which is unaudited) sets forth the capitalization of EM Fund and SEM Fund as of March 31, 2010, and on a pro forma basis as of that date giving effect to the proposed acquisition of assets of the EM Fund at net asset value.

Performance Information. The following bar charts and tables provide some indication of the risks of investing in the Fund by showing changes in the performance from year to year and how the Fund’s average annual returns over time compare with those of broad-based securities market indices. The returns in the bar chart of EM Fund are for Class B shares and the returns in the bar chart for SEM Fund are for Class A shares, and do not reflect a sales charge. If the sales charge was reflected, the returns would be lower. Past performance (both before and after taxes) is no guarantee of future results. Each Fund’s performance reflects the effects of expense reductions. Absent these reductions, performance would have been lower. Updated Fund performance information can be obtained by visiting www.eatonvance.com.

EM Fund

During the ten years ended December 31, 2009, the highest quarterly total return for Class B was 29.02% for the quarter ended June 30, 2009, and the lowest quarterly return was –30.61% for the quarter ended December 31, 2008.

SEM Fund

During the period from December 31, 2006 through December 31, 2009, the highest quarterly total return for Class A was 37.04% for the quarter ended June 30, 2009, and the lowest quarterly return was –30.11% for the quarter ended December 31, 2008.

These returns reflect the maximum sales charge for Class A (5.75%) and any applicable contingent deferred sales charge (“CDSC”) for Class B. Class A of SEM Fund commenced operations on June 30, 2006. Life of Fund returns for SEM Fund are calculated from June 30, 2006. The MSCI Emerging Markets Index and the S&P IFCI Emerging Markets Index are unmanaged indices of common stocks

traded in emerging markets. Investors cannot invest directly in an Index. (Source for MSCI Emerging Markets Index: Lipper, Inc.; source for S&P IFCI Emerging Markets Index: Bloomberg.)

After-tax returns are calculated using the highest historical individual federal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on a shareholder’s tax situation and the actual characterization of distributions, and may differ from those shown. After-tax returns are not relevant to shareholders who hold shares in tax-deferred accounts or to shares held by nontaxable entities. After-tax returns for Class A shares will vary from the after-tax returns presented for Class B shares. Return After Taxes on Distributions for a period may be the same as Return Before Taxes for that period because no taxable distributions were made during that period. Also, Return After Taxes on Distributions and Sale of Fund Shares for a period may be greater than or equal to Return After Taxes on Distributions for the same period because of losses realized on the sale of Fund shares.

Management’s Discussion of Fund Performance. The total returns of SEM Fund and the factors that materially affected its performance during the most recent fiscal year are contained in its Annual Report dated October 31, 2009, which is incorporated by reference into this Proxy Statement/Prospectus and relevant portions of which are attached hereto as Appendix B.

The performance of EM Fund is described under the captions “Performance Information” and “Portfolio Composition” in the Annual Report of EM Fund for the year ended December 31, 2009, which was previously mailed to EM Fund shareholders and is incorporated by reference into this Proxy Statement/Prospectus.

PRINCIPAL RISK FACTORS

Generally. As discussed above, the Funds have substantially similar investment objectives and policies and, as such, are subject to substantially similar types of risks. See “Principal Risks” in the SEM Fund Prospectus for a description of the principal risks of investing in the Fund.

The SEM Fund’s investment adviser uses quantitative investment techniques and analyses in making investment decisions for the Fund, but there can be no assurance that these will achieve the desired results. The SEM Fund’s strategy is highly dependent on a quantitatively-based country weighting process, a structured sector allocation and a proprietary disciplined rebalancing model that generally has not been independently tested or otherwise reviewed. Securities and exposures selected using this proprietary strategy may be weighted differently than in capitalization-weighted indices and therefore may differ in relative contribution to performance.

Principal Differences between the EM Fund and the SEM Fund. Although EM Fund and the SEM Fund have similar policies, the SEM Fund may invest in additional types of derivatives that the EM Fund did not invest in. To the extent that the SEM Fund utilizes such derivatives, the SEM Fund may have a higher risk profile than the EM Fund.

COMPARATIVE INFORMATION ON SHAREHOLDER RIGHTS

General. EM Fund is a series of Eaton Vance Special Investment Trust and SEM Fund is a series of Eaton Vance Mutual Funds Trust. Each Trust is a Massachusetts business trust governed by an

Amended and Restated Declaration of Trust dated September 27, 1993 and August 17, 1993, respectively, as amended from time to time, and by applicable Massachusetts law.

Shareholder Liability. Under Massachusetts law, shareholders of a Massachusetts business trust could, under certain circumstances, be held personally liable for the obligations of the trust, including its other series. However, the Declaration of Trust disclaims shareholder liability for acts or obligations of the trust and other series of the trust and requires that notice of such disclaimer be given in each agreement, obligation, or instrument entered into or executed by the trust or the trustees. Indemnification out of the trust property for all losses and expenses of any shareholder held personally liable by virtue of his or her status as such for the obligations of the trust is provided for in the Declaration of Trust and By-Laws. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is considered to be remote because it is limited to circumstances in which the respective disclaimers are inoperative and t he series would be unable to meet their respective obligations.

Copies of the Declaration of Trust may be obtained from the Trust upon written request at its principal office or from the Secretary of the Commonwealth of Massachusetts.

VOTING INFORMATION

What is the Vote Required to Approve the Proposal?

The affirmative vote of the holders of a majority of EM Fund’s outstanding shares, as defined in the 1940 Act, is required to approve the Plan. Such “majority” vote is the vote of the holders of the lesser of (a) 67% or more of the shares of EM Fund present or represented by proxy at the Special Meeting, if the holders of more than 50% of the outstanding shares are present or represented by proxy, or (b) 50% of the outstanding shares of EM Fund. Class A and Class B shareholders of EM Fund will vote together as a single group. Approval of the Plan by EM Fund shareholders is a condition of the consummation of the Reorganization.

How Do I Vote in Person?

If you do attend the Special Meeting and wish to vote in person, we will provide you with a ballot prior to the vote. However, if your shares are held in the name of your broker, bank or other nominee, you must bring a letter from the nominee indicating that you are the beneficial owner of the shares on the Record Date and authorizing you to vote. Please call the Fund at 1-800-262-1122 Monday through Friday, 8:00 a.m. to 6:00 p.m. Eastern time if you have any questions about attending the Special Meeting. If you plan to attend the Special Meeting in person, please be prepared to present photo identification.

How Do I Vote By Proxy?

Whether you plan to attend the Special Meeting or not, we urge you to complete, sign and date the enclosed proxy card and to return it promptly in the envelope provided. Returning the proxy card will not affect your right to attend the Special Meeting and vote.

If you properly fill in and sign your proxy card and send it to us in time to vote at the Special Meeting, your “proxy” (the individual named on your proxy card) will vote your shares as you have directed. If you sign your proxy card but do not make specific choices, your proxy will vote your shares “FOR” the proposal and in accordance with management’s recommendation on other matters.

If you authorize a proxy, you may revoke it at any time before it is exercised by sending in another proxy card with a later date or by notifying the Secretary of the EM Fund before the Special Meeting that you have revoked your proxy; such notice must be in writing and sent to the Secretary of the EM Fund at the address set forth on the cover page of this Proxy Statement/Prospectus. In addition, although merely attending the Special Meeting will not revoke your proxy, if you are present at the Special Meeting you may withdraw your proxy and vote in person. Shareholders may also transact any other business not currently contemplated that may properly come before the Special Meeting in the discretion of the proxies or their substitutes.

How Will Proxies be Solicited and Tabulated?

The expense of preparing, printing and mailing this Proxy Statement/Prospectus and enclosures and the costs of soliciting proxies on behalf of the EM Fund’s Board of Trustees will be borne by the EM Fund. Proxies will be solicited by mail and may be solicited in person or by telephone, facsimile or other electronic means by officers of the EM Fund, by personnel of Eaton Vance, by the EM Fund’s transfer agent, PNC Global Investment Servicing, by broker-dealer firms or by a professional solicitation organization. The EM Fund has retained Computershare Fund Services (“Computershare”) to assist in the solicitation of proxies, for which the EM Fund will pay an estimated fee of approximately $20,000, which assumes a moderate level of solicitation activity. If a greater solicitation effort is required, the solicitation costs would be higher. The expenses connected with the solicitation of this proxy and with any further proxies which may be solicited by the EM Fund 6;s officers, by Eaton Vance personnel, by the transfer agent, by broker-dealer firms or by Computershare, in person, or by telephone, by telegraph, by facsimile or other electronic means, will be borne by the EM Fund. A written proxy may be delivered to the EM Fund or its transfer agent prior to the meeting by facsimile machine, graphic communication

equipment or other electronic transmission. The EM Fund will reimburse banks, broker-dealer firms, and other persons holding shares registered in their names or in the names of their nominees, for their expenses incurred in sending proxy material to and obtaining proxies from the beneficial owners of such shares. Total estimated costs of the Reorganization are approximately $70,000.

Shareholders also may choose to give their proxy votes by telephone rather than return their proxy cards. Please see the proxy card for details. The EM Fund may arrange for Eaton Vance, its affiliates or agents to contact shareholders who have not returned their proxy cards and offer to have votes recorded by telephone. If the EM Fund records votes by telephone, it will use procedures designed to authenticate shareholders’ identities, to allow shareholders to authorize the voting of their shares in accordance with their instructions, and to confirm that their instructions have been properly recorded. If the enclosed proxy card is executed and returned, or a telephonic vote is delivered, that vote may nevertheless be revoked at any time prior to its use by written notification received by the EM Fund, by the execution of a later-dated proxy card, by the EM Fund’s receipt of a subsequent valid telephonic vote, or by attending the meeting and voting in person.

All proxy cards solicited by the Board of Trustees that are properly executed and telephonic votes that are properly delivered and received by the Secretary prior to the meeting, and which are not revoked, will be voted at the meeting. Shares represented by such proxies will be voted in accordance with the instructions thereon. If no specification is made on the proxy card, it will be voted FOR the matters specified on the proxy card. Abstentions and broker non-votes (i.e., proxies from brokers or nominees indicating that such persons have not received instructions from the beneficial owner or other person entitled to vote shares on a particular matter with respect to which the broker or nominee does not have discretionary power) will be treated as shares that are present at the meeting, but which have not been voted. Accordingly, abstentions and broker non-votes will assist the EM Fund in obtaining a quorum, but may have the effect of a “No” vote on the proposal.

How is a Quorum Determined and What Happens if There is an Adjournment?

What constitutes a quorum for purposes of conducting a valid shareholder meeting, such as the Special Meeting, is set forth in the Trust’s By-Laws. Under the By-Laws of the Trust, the presence, in person or by proxy, of a majority of the outstanding shares is necessary to establish a quorum.

If a quorum is not present at the Special Meeting, the persons named as proxies in the enclosed proxy card may propose to adjourn the meeting to permit further solicitation of proxies in favor of the proposal. A meeting, including the Special Meeting, may be adjourned one or more times. Each such adjournment requires the affirmative vote of the holders of a majority of EM Fund’s shares that are present at the meeting, in person or by proxy. The persons named as proxies will vote in favor of or against, or will abstain with respect to, adjournment in the same proportions they are authorized to vote for or against, or to abstain with respect to, the proposal.

THE TRUSTEES OF THE TRUST, INCLUDING THE INDEPENDENT TRUSTEES, RECOMMEND
APPROVAL OF THE PLAN OF REORGANIZATION.

DISSENTERS RIGHTS

Neither the Declaration of Trust nor Massachusetts law grants the shareholders of the EM Fund any rights in the nature of dissenters rights of appraisal with respect to any action upon which such shareholders may be entitled to vote; however, the normal right of mutual fund shareholders to redeem their shares (subject to any applicable contingent deferred sales charges) is not affected by the proposed Reorganization.

SEM FUND FINANCIAL HIGHLIGHTS

The financial highlights are intended to help you understand SEM Fund’s financial performance for the periods indicated. Certain information in the table reflects the financial results for a single Fund share. The total returns in the table represent the rate an investor would have earned (or lost) on an investment in the Fund assuming reinvestment of all distributions at net asset value. This information has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, except that information prior to November 1, 2006 was audited by another independent registered public accounting firm.

		so that, in the judgment of Mutual Funds Trust and Special Investment Trust, accurate
		appraisal of the net assets of the Acquired Fund to be transferred hereunder or the

		shareholders to be certified as such by the transfer agent for Special Investment Trust ),
		to be registered on the books of the Acquiring Fund, in full and fractional Acquiring Fund
		Shares, in the name of each such shareholder, and the Acquiring Fund agrees promptly
		to transfer the Acquiring Fund Shares then credited to the account of the Acquired Fund
		on the books of the Acquiring Fund to open accounts on the share records of the
		Acquiring Fund in the names of the Acquired Fund shareholders in accordance with said
		instruction. Each Acquired Fund shareholder shall receive Class A shares of the
		Acquiring Fund. All issued and outstanding Acquired Fund Shares shall thereupon be

Annual Report

Management's Discussion of Fund Performance

Eaton Vance Structured Emerging Markets Fund as of October 31, 2009

MANAGEMENT’S DISCUSSION OF FUND PERFORMANCE

Economic and Market Conditions

• Despite an extremely volatile year, emerging markets generated strong positive performance, as measured by the MSCI Emerging Markets Index (the Index), which recorded a return of 64.13% for the 12 months ending October 31, 2009.¹As the period began late last fall, global equities were already in the midst of a dramatic decline, dragged lower by the failure or near-collapse of several major financial institutions struggling under the enormous weight of troubled assets. On the verge of illiquidity, the credit markets virtually ceased operating, worldwide economic activity ground to a near standstill, and anxious equity investors stayed on the sidelines. At the beginning of the second quarter, however, equity markets began a rally in response to indications that the concerted global effort by world banks to alleviate the credit crisis and stimulate economic growth was succeeding. Th e volatile period finished on a decidedly positive note, with many market indexes for European, U.S. and Asian equities posting solid annual gains.

• Against this backdrop, emerging markets fared very well, with some economies proving more resilient to the financial crisis and global recession than anticipated. Equity indexes tracking the performance of emerging markets widely outperformed the 27.71% return of foreign developed markets, as measured by the MSCI Europe, Australasia and Far East Index.

• Top performers in the Index on an absolute-return basis for the year ending October 31, 2009, included Indonesia (+126%), Peru (+117%), Russia (+110%), Colombia (+94%), Brazil (+92%) and China (+83%). The Index’s nearly 20% weighting in China made the most significant contribution to returns, followed by a 15% allocation to Brazil. By contrast, countries such as Pakistan (-44%) and Jordan (-25%) did not fare as well.

Past performance is no guarantee of future results. Returns are historical and are calculated by determining the percentage change in net asset value or offering price (as applicable) with all distributions reinvested. Investment return and principal value will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Performance is for the stated time period only; due to market volatility, the Fund’s current performance may be lower or higher than the quoted return. For performance as of the most recent month end, please refer to www.eatonvance.com.

Management Discussion

• For the year ending October 31, 2009, the Fund recorded a double-digit return, although it under-performed the Index, its primary benchmark, and the S&P/IFCI Emerging Markets Index, its secondary benchmark. Looking at individual countries, China and Brazil had strong positive returns but the Fund’s underweight in both countries detracted from performance relative to the Index. Fund holdings in Nigeria and United Arab Emirates also were a drag on relative performance, as was the Fund’s exposure to Qatar, Jordan, Kuwait, Ghana and Saudi Arabia. Russia and Indonesia were among the top contributors to the Fund’s return, as the Fund was significantly overweighted in both countries versus the Index. An overweight to Argentina, as well as underweightings in Taiwan and Korea, also added to performance.

• With any multicountry portfolio, country selection and weighting have the largest effect on the risk and return experience of the Fund’s strategy. Our research into emerging countries has resulted in some important observations. Individually, emerging markets can be volatile, but they also exhibit relatively low correlations among each other and developed markets. We believe that due to this tendency to move relatively

¹It is not possible to invest directly in an Index or a Lipper Classification. The Indices’ total returns do not reflect commissions or expenses that would have been incurred if an investor individually purchased or sold the securities represented in the Indices. MSCI Index returns reflect dividends net of any applicable foreign withholding taxes. The Lipper total return is the average total return, at net asset value, of the funds that are in the same Lipper Classification as the Fund.

²These returns do not include the 5.75% maximum sales charge for Class A shares or the applicable contingent deferred sales charge (CDSC) for Class C shares. If sales charges were deducted, the returns would be lower. Class I shares are offered to certain investors at net asset value. Absent expense limitations by the adviser, the sub-adviser and the administrator, the returns would be lower.

Fund shares are not insured by the FDIC and are not deposits or other obligations of, or guaranteed by, any depository institution. Shares are subject to investment risks, including possible loss of principal invested.

Eaton Vance Structured Emerging Markets Fund as of October 31, 2009

MANAGEMENT’S DISCUSSION OF FUND PERFORMANCE

independently, a structured portfolio that balances exposure to a broad array of emerging market countries can substantially reduce volatility compared to the level found in individual countries or more traditionally concentrated active strategies. While during the depths of the global financial crisis, there was a phenomenon where cross-country correlations rose and markets behaved more similarly than usual. However, they reverted to the historic norm of moving independent of each other as markets recovered throughout the year.

The views expressed throughout this report are those of the portfolio managers and are current only through the end of the period of the report as stated on the cover. These views are subject to change at any time based upon market or other conditions, and the investment adviser disclaims any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for a fund are based on many factors, may not be relied on as an indication of trading intent on behalf of any Eaton Vance fund. Portfolio information provided in the report may not be representative of the Fund’s current or future investments and may change due to active management.

FUND PERFORMANCE

The line graph and table set forth below provide information about the Fund’s performance. The line graph compares the performance of Class A of the Fund with that of the MSCI Emerging Markets Index and the S&P/IFCI Emerging Markets Index, each an unmanaged index of common stocks traded in emerging markets and available to foreign investors. The lines on the graph represent the total returns of a hypothetical investment of $10,000 in each of Class A, the MSCI Emerging Markets Index and the S&P/IFCI Emerging Markets Index. Class A total returns are presented at net asset value and maximum public offering price. The table includes the total returns of each Class of the Fund at net asset value and maximum public offering price. The performance presented below does not reflect the deduction of taxes, if any, that a shareholder would pay on distributions or redemptions of Fund shares.

*Source: Lipper, Bloomberg. Class A of the Fund commenced investment operations on 6/30/06.

A $10,000 hypothetical investment at net asset value in Class C shares and Class I shares on 6/30/06 (inception date) would have been valued at $12,398 and $12,814, respectively, on 10/31/09. It is not possible to invest directly in an Index. The Indices’ total returns do not reflect commissions or expenses that would have been incurred if an investor individually purchased or sold the securities represented in the Indices.

If sales charges were deducted, the returns would be lower. SEC Average Annual Total Returns for Class A reflect the maximum 5.75% sales charge and, for Class C, reflect a 1% CDSC for the first year. Class A and Class I shares are subject to a 1% redemption fee if redeemed or exchanged within 90 days of settlement of purchase. Class I shares are offered to certain investors at net asset value. Absent expense limitations by the adviser, the sub-adviser and the administrator, the returns would be lower.

Eaton Vance Structured Emerging Markets Fund as of October 31, 2009

FUND EXPENSES

Example: As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchases and redemption fees (if applicable); and (2) ongoing costs, including management fees; distribution or service fees; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (May 1, 2009 – October 31, 2009).

Actual Expenses: The first section of the table below provides information about actual account values and actual expenses. You may use the information in this section, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes: The second section of the table below provides information about hypothetical account values and hypothetical expenses based on the actual Fund expense ratio and an assumed rate of return of 5% per year (before expenses), which is not the actual return of the Fund. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in your Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or redemption fees (if applicable). Therefore, the second section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would be higher.

Class C		$1,000.00	$1,409.90	$14.27**

Class C		$1,000.00	$1,013.40	$11.93**
Class I		$1,000.00	$1,018.40	$6.87**

*	Expenses are equal to the Fund’s annualized expense ratio of 1.60% for Class A shares, 2.35% for Class C shares and
	1.35% for Class I shares, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the
	one-half year period). The Example assumes that the $1,000 was invested at the net asset value per share determined at
	the close of business on April 30, 2009.

**	Absent an expense limitation by affiliates, the expenses would be higher.
