&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Implementation of Investment Objective

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Risks

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Portfolio Holdings

The mutual funds advised by Eaton Vance Management ("Eaton Vance") or Boston Management and Research ("BMR") ("Eaton Vance funds") have established policies and procedures with respect to the disclosure of portfolio holdings and other information concerning Fund characteristics. A description of these policies and procedures is incorporated by reference from "Shareholder Account Features – Information about the Funds" in the Feeder Fund [prospectus](https://www.sec.gov/ix?doc=/Archives/edgar/data/0000745463/000094039423000325/evmft-20221031.htm).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Capital Stock

Information concerning interests in the Portfolio is incorporated by reference from "Management and Organization – Portfolio Organization" in the Feeder Fund [SAI](https://www.sec.gov/ix?doc=/Archives/edgar/data/0000745463/000094039423000325/evmft-20221031.htm).

**Item 11. Shareholder Information**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Pricing

The net asset value ("NAV") of the Portfolio is determined as of the close of the New York Stock Exchange (the "NYSE") (each a "Portfolio Business Day") (normally 4:00 p.m. Eastern time) on each day that the NYSE is open for business (typically Monday through Friday) (the "Pricing Time"). Interests in the Portfolio generally will not be priced on days that the NYSE is closed. If the NYSE is closed due to inclement weather, technology problems or any other reason on a day it would normally be open for business, or the NYSE has an unscheduled early closing on a day it has opened for business, the Portfolio reserves the right to treat such day as a business day and accept purchase and redemption orders until, and calculate its NAV as of, the normally scheduled close of regular trading on the NYSE for that day, so long as BMR believes there generally remains an adequate market to obtain reliable and accurate market quotations. The Portfolio may elect to remain open and price its interests on days when the NYSE is closed but the primary securities markets on which the Portfolio's securities trade remain open. Trading of securities that are primarily listed on foreign exchanges may take place on weekends and other days when the Portfolio does not price its interests.

The Portfolio's Board of Trustees has adopted procedures for valuing investments (the "Procedures") and has delegated to the investment adviser the daily valuation of such investments. Information concerning the Procedures is incorporated by reference from "Valuing Shares" in the Feeder Fund [prospectus](https://www.sec.gov/ix?doc=/Archives/edgar/data/0000745463/000094039423000325/evmft-20221031.htm).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) and (c) Purchases and Redemptions

As described above, interests in the Portfolio are issued solely in private placement transactions that do not involve any "public offering" within the meaning of Section 4(a)(2) of the 1933 Act. There is no minimum initial or subsequent investment in the Portfolio. The Portfolio reserves the right to transact in-kind to the extent permitted under the Investment Company Act of 1940, as amended (the "1940 Act") and its rules, or any relief from those provisions. The Portfolio reserves the right to cease accepting investments at any time or to reject any investment order. The placement agent for the Portfolio is Eaton Vance Distributors, Inc. ("EVD"), an indirect wholly owned subsidiary of Morgan Stanley. Prior to March 1, 2021, EVD was a direct wholly owned subsidiary of Eaton Vance Corp. The principal business address of EVD is Two International Place, Boston, Massachusetts 02110. EVD receives no compensation from the Portfolio for serving as the placement agent.

Each investor in the Portfolio may add to or reduce its investment in the Portfolio on each Portfolio Business Day as of the Pricing Time. The value of each investor's interest in the Portfolio will be determined by multiplying the NAV of the Portfolio by the percentage, determined on the prior Portfolio Business Day, which represents that investor's share of the aggregate interests in the Portfolio on such prior day. Any additions or withdrawals for the current Portfolio Business Day will then be recorded. Each investor's percentage of the aggregate interest in the Portfolio will then be recomputed as a percentage equal to a fraction (i) the numerator of which is the value of such investor's investment in the Portfolio as of the Pricing Time on the prior Portfolio Business Day plus or minus, as the case may be, the amount of any additions to or withdrawals from the investor's investment in the Portfolio on the current Portfolio Business Day and (ii) the denominator of which is the aggregate NAV of the Portfolio as of the Pricing Time on the prior Portfolio Business Day plus or minus, as the case may be, the amount of the net additions to or withdrawals from the aggregate investment in the Portfolio on the current Portfolio Business Day by all investors in the Portfolio. The percentage so determined will then be applied to determine the value of the investor's interest in the Portfolio for the current Portfolio Business Day.

&nbsp;&nbsp;&nbsp;&nbsp;An investor in the Portfolio may withdraw all of (redeem) or any portion of (decrease) its interest in the Portfolio if a withdrawal request in proper form is furnished by the investor to the Portfolio. All withdrawals will be effected as of the next Pricing Time. The proceeds of a withdrawal will be paid by the Portfolio normally on the Portfolio Business Day the withdrawal is effected, but in any event within seven days. The Portfolio reserves the right to pay the proceeds of a withdrawal (whether a redemption or decrease) by a distribution in kind of portfolio securities (instead of cash). The securities so distributed would be valued at the same amount as that assigned to them in calculating the NAV for the interest (whether complete or partial) being withdrawn. If an investor received a distribution in kind upon such withdrawal, the investor could incur brokerage and other charges in converting the securities to cash.

The right of any investor to receive payment with respect to any withdrawal may be suspended or the payment of the withdrawal proceeds postponed during any period in which the NYSE is closed (other than weekends or holidays) or trading on the NYSE is restricted as determined by the Securities and Exchange Commission (the "SEC") or, to the extent otherwise permitted by the 1940 Act, if an emergency exists as determined by the SEC, or during any other period permitted by order of the SEC for the protection of investors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Dividends and Distributions

The Portfolio will allocate at least annually among its investors each investor's distributive share of the Portfolio's net investment income, net realized capital gains, and any other items of income, gain, loss, deduction or credit. The Portfolio's net investment income consists of all income accrued on the Portfolio's assets, less all actual and accrued expenses of the Portfolio, determined in accordance with accounting principles generally accepted in the United States of America. Allocations of taxable income or loss may be made in a different manner in order to comply with U.S. federal income tax rules.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) Frequent Purchases and Redemptions of Portfolio Interests

In general, frequent purchases and redemptions of investment company shares may dilute the value of shares held by long-term shareholders. Excessive purchases and redemptions may disrupt efficient portfolio management, forcing an investment company to sell portfolio securities at inopportune times to raise cash, or cause increased expenses such as increased brokerage costs, realization of taxable capital gains, including short-term capital gains taxable as ordinary income, without attaining any investment advantage, or increased administrative costs. The Portfolio receives purchase and redemption requests from its investors (including the Feeder Fund) on a regular basis. These requests are primarily in response to transaction activity prompted by shareholders in such investors or allocation decisions by the managers of such investors. The Boards of Trustees of the Eaton Vance funds have adopted policies to discourage short-term trading and market timing and to seek to minimize the potentially detrimental effects of frequent purchases and redemptions of shares of those Funds. Additional information about these policies is included under "Purchasing Shares – Restrictions on Excessive Trading and Market Timing" in the Feeder Fund [prospectus](https://www.sec.gov/ix?doc=/Archives/edgar/data/0000745463/000094039423000325/evmft-20221031.htm).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) Tax Consequences

Under the anticipated method of operation of the Portfolio, the Portfolio should be classified as a partnership under the Code and should not be subject to any U.S. federal income tax. However, each investor in the Portfolio will be required to take into account its allocable share of the Portfolio's taxable ordinary income and capital gain in determining its U.S. federal income tax liability, if any. The determination of each such share will be made in accordance with the governing instruments of the Portfolio, which are intended to comply with the requirements of the Code and the regulations promulgated thereunder (the "Treasury Regulations").

The Portfolio expects to manage its assets in such a way that an investment company investing in the Portfolio will be able to satisfy the income and asset diversification requirements of Subchapter M of the Code, assuming that it invests all of its assets in the Portfolio or other portfolios that so manage their assets or other regulated investment companies ("RICs") that so manage their assets.

**Item 12. Distribution Arrangements**

Not applicable.

**PART B**

This Part B should be read in conjunction with Part A. Capitalized terms used in this Part B and not otherwise defined have the meaning given them in Part A.

**Item 18. Control Persons and Principal Holders of Securities**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) - (b) Control Persons and Principal Holders

As of February 1, 2023, the Feeder Fund controlled the Portfolio by virtue of owning approximately 84.69% of the value of the outstanding interests in the Portfolio. Because the Feeder Fund controls the Portfolio, the Feeder Fund may take actions without the approval of any other investor. The Feeder Fund has informed the Portfolio that it will vote in accordance with the requirements of the 1940 Act whenever requested to vote on Portfolio matters. The Feeder Fund is a series of Eaton Vance Mutual Funds Trust (the "Trust"), an open-end management investment company organized as a business trust under the laws of the Commonwealth of Massachusetts. The address of the Feeder Fund and the Trust is Two International Place, Boston, MA 02110.

As of February 1, 2023, Eaton Vance Floating Rate & High Income Fund owned of record and beneficially 15.31% of the value of the outstanding interests in the Portfolio.

The Portfolio's investment adviser has claimed an exclusion from the definition of "commodity pool operator" under the Commodity Exchange Act with respect to its management of the Portfolio. Accordingly neither the Portfolio nor the investment adviser with respect to the operation of the Portfolio is subject to registration or regulation as a commodity pool operator under the Commodity Exchange Act. Because of their management of other strategies, Eaton Vance and BMR are registered with the Commodity Futures Trading Commission ("CFTC") as commodity pool operators. Eaton Vance is also registered as a commodity trading advisor. BMR claims an exemption of "commodity trading advisor." The CFTC has neither reviewed nor approved the Portfolio's investment strategies or this Registration Statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Principal Underwriter

EVD, an indirect wholly owned subsidiary of Morgan Stanley, is the Portfolio's placement agent. Prior to March 1, 2021, EVD was a direct wholly owned subsidiary of Eaton Vance Corp. The principal business address of EVD is Two International Place, Boston, Massachusetts 02110.

Information concerning the brokerage practices of the Portfolio is incorporated by reference from "Portfolio Securities Transactions" in the Feeder Fund [SAI](https://www.sec.gov/ix?doc=/Archives/edgar/data/0000745463/000094039423000325/evmft-20221031.htm).

**Item 22. Capital Stock and Other Securities**

Under the Portfolio's Declaration of Trust, the Trustees are authorized to issue interests in the Portfolio. Investors are entitled to participate pro rata in distributions of taxable income, loss, gain and credit of the Portfolio. Upon termination of the Portfolio, the Trustees shall liquidate the assets of the Portfolio and apply and distribute the proceeds thereof as follows: (a) first, to the payment of all debts and obligations of the Portfolio to third parties including, without limitation, the retirement of outstanding debt, including any debt owed to holders of record of interests in the Portfolio ("Holders") or their affiliates, and the expenses of liquidation, and to the setting up of any reserves for contingencies which may be necessary; and (b) second, in accordance with the Holders' positive Book Capital Account balances after adjusting Book Capital Accounts for certain allocations provided in the Declaration of Trust and in accordance with the requirements described in Treasury Regulations Section 1.704-1(b)(2)(ii)(b)(2). Notwithstanding the foregoing, if the Trustees shall determine that an immediate sale of part or all of the assets of the Portfolio would cause undue loss to the Holders, the Trustees, in order to avoid such loss, may, after having given notification to all the Holders, to the extent not then prohibited by the law of any jurisdiction in which the Portfolio is then formed or qualified and applicable in the circumstances, either defer liquidation of and withhold from distribution for a reasonable time any assets of the Portfolio except those necessary to satisfy the Portfolio's debts and obligations or distribute the Portfolio's assets to the Holders in liquidation. The Trustees may authorize the issuance of certificates of beneficial interest to evidence the ownership of interests in the Portfolio.

Each Holder is entitled to vote in proportion to the amount of its interest in the Portfolio. Holders do not have cumulative voting rights. The Portfolio is not required and has no current intention to hold annual meetings of Holders, but the Portfolio will hold meetings of Holders when in the judgment of the Portfolio's Trustees it is necessary or desirable to submit matters to a vote of Holders at a meeting. Any action which may be taken by Holders may be taken without a meeting if Holders holding more than 50% of all interests entitled to vote (or such larger proportion thereof as shall be required by any express provision of the Declaration of Trust of the Portfolio) consent to the action in writing and the consents are filed with the records of meetings of Holders.

The Portfolio's Declaration of Trust may be amended by vote of Holders of more than 50% of all interests in the Portfolio at any meeting of Holders or by an instrument in writing without a meeting, executed by a majority of the Trustees and consented to by the Holders of more than 50% of all interests. The Trustees may also amend the Declaration of Trust (without the vote or consent of Holders) to change the Portfolio's name or the state or other jurisdiction whose law shall be the governing law, to supply any omission or cure, correct or supplement any ambiguous, defective or inconsistent provision, to conform the Declaration of Trust to applicable federal law or regulations or the requirements of the Code, or to change, modify or rescind any provision, provided that such change, modification or rescission is determined by the Trustees to be necessary or appropriate and not to have a materially adverse effect on the financial interests of the Holders. No amendment of the Declaration of Trust which would change any rights with respect to any Holder's interest in the Portfolio by reducing the amount payable thereon upon liquidation of the Portfolio may be made, except with the vote or consent of the Holders of two-thirds of all interests. References in the Declaration of Trust and in Part A or this Part B to a specified percentage of, or fraction of, interests in the Portfolio, means Holders whose combined Book Capital Account balances represent such specified percentage or fraction of the combined Book Capital Account balance of all, or a specified group of, Holders.

The Portfolio may merge or consolidate with any other corporation, association, trust or other organization or may sell, lease or exchange all or substantially all of its property, including its good will, upon such terms and conditions and for such consideration when and as authorized by the Trustees and without any authorization, vote or consent of the Holders, except as may otherwise be required by applicable law, and any such merger, consolidation, sale, lease or exchange shall be deemed for all purposes to have been accomplished under and pursuant to the statutes of the Commonwealth of Massachusetts. The Portfolio may be terminated (i) by the affirmative vote of Holders of not less than two-thirds of all interests at any meeting of Holders or by an instrument in writing without a meeting, consented to by Holders of not less than two-thirds of all interests or (ii) by the approval of a majority of the Trustees then in office to be followed by written notice to the Holders.

The Declaration of Trust provides that obligations of the Portfolio are not binding upon the Trustees individually but only upon the property of the Portfolio and that the Trustees will not be liable for any action or failure to act, but nothing in the Declaration of Trust protects a Trustee against any liability to which he would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of his office.

**Item 23. Purchase, Redemption, and Pricing of Shares**

See Item 11 herein. The Procedures adopted by the Board for valuing Portfolio assets are incorporated by reference from "Calculation of Net Asset Value" in the Feeder Fund [SAI](https://www.sec.gov/ix?doc=/Archives/edgar/data/0000745463/000094039423000325/evmft-20221031.htm).

**Item 24. Taxation of the Portfolio**

Provided the Portfolio is operated at all times during its existence in accordance with certain organizational and operational documents, the Portfolio should be classified as a partnership under the Code, and it should not be a "publicly traded partnership" within the meaning of Section 7704 of the Code. Consequently, the Portfolio does not expect that it will be required to pay any U.S. federal income tax, and a Holder will be required to take into account in determining its U.S. federal income tax liability its allocable share of the Portfolio's income, gains, losses, deductions and credits.

Under Subchapter K of the Code, a partnership is considered to be either an aggregate of its members or a separate entity depending upon the factual and legal context in which the question arises. Under the aggregate approach, each partner is treated as an owner of an undivided interest in partnership assets and operations. Under the entity approach, the partnership is treated as a separate entity in which partners have no direct interest in partnership assets and operations. In the case of a Holder that seeks to qualify as a RIC, the aggregate approach should apply, and each such Holder should accordingly be deemed to own a proportionate share of each of the assets of the Portfolio and to be entitled to the gross income of the Portfolio attributable to that share for applicable purposes of Subchapter M of the Code.

In order to enable a Holder (that is otherwise eligible) to qualify as a RIC, the Portfolio intends to satisfy the requirements of Subchapter M of the Code relating to sources of income and diversification of assets as if they were applicable to the Portfolio and to permit withdrawals in a manner that will enable a Holder that is a RIC to comply with the distribution requirements applicable to RICs (including those under Sections 852 and 4982 of the Code). The Portfolio will allocate at least annually to each Holder such Holder's distributive share of the Portfolio's net investment income, net realized capital gains, and any other items of income, gain, loss, deduction or credit (including unrealized gains at the end of the Portfolio's fiscal year on certain options and futures transactions that are required to be marked-to-market) in a manner intended to comply with the Code and applicable Treasury Regulations.

To the extent the cash proceeds of any withdrawal (or, under certain circumstances, such proceeds plus the value of any marketable securities distributed to an investor) ("liquid proceeds") exceed a Holder's adjusted basis of its interest in the Portfolio, the Holder will generally realize a gain for U.S. federal income tax purposes. If, upon a complete withdrawal, a Holder receives only liquid proceeds (and/or unrealized receivables) and the Holder's adjusted basis of its interest exceeds the liquid proceeds of such withdrawal and the Holder's basis in any unrealized receivables, the Holder will generally realize a loss for U.S. federal income tax purposes. In addition, on a distribution to a Holder from the Portfolio, (i) income may be recognized if the distribution changes a distributee's share of any unrealized receivables held by the Portfolio and (ii) gain or loss may be recognized to a Holder that contributed property to the Portfolio. The tax consequences of a withdrawal of property (instead of or in addition to liquid proceeds) will be different and will depend on the specific factual circumstances. A Holder's adjusted basis of an interest in the Portfolio will generally be the aggregate price paid therefor (including the adjusted basis of contributed property and any gain recognized on the contribution thereof), increased by the amounts of the Holder's distributive share of items of income (including income exempt from U.S. federal income taxation) and realized net gain of the Portfolio, and reduced, but not below zero, by (i) the amounts of the Holder's distributive share of items of Portfolio deductions or loss, (ii) the amount of any cash distributions (including distributions of income exempt from U.S. federal income taxation and cash distributions on withdrawals from the Portfolio) and the adjusted basis to the Holder of any property received by such Holder other than in liquidation, and (iii) the Holder's distributive share of the Portfolio's nondeductible expenditures not properly chargeable to the Holder's capital account. Increases or decreases in a Holder's share of the Portfolio's liabilities may also result in corresponding increases or decreases in such adjusted basis.

A partnership has the option to make an election to adjust the basis of the partnership's assets in the event of a distribution of partnership property to a partner, or a transfer of a partnership interest. This optional adjustment could either increase or decrease such basis depending on the relevant facts. There can be no assurance that the Portfolio will make such an election in the future. However, this basis adjustment is mandatory in certain circumstances.

The Portfolio's investments in options, futures contracts, hedging transactions, forward contracts and certain other transactions will be subject to special tax rules (including mark-to-market, constructive sale, straddle, wash sale, short sale and other rules), the effect of which may be to accelerate income to the Portfolio, defer Portfolio losses, cause adjustments to the holding periods of Portfolio securities, convert capital gain into ordinary income and convert short-term capital losses into long-term capital losses. These rules could therefore affect the amount, timing and character of the income recognized by Holders, including Holders who intend to qualify as RICs.

The Portfolio's investments, if any, in securities issued with original issue discount or securities acquired at a market discount (if an election is made to include accrued market discount in current income) will cause it to realize income prior to the receipt of cash payments with respect to those securities. In order to enable a Holder to distribute its proportionate share of this income, the Portfolio may be required to liquidate portfolio securities that it otherwise might have continued to hold in order to generate cash that the Holder may withdraw from the Portfolio for subsequent distribution to such Holder's shareholders.

The Portfolio may be subject to foreign taxes on its income (including, in some cases, capital gains) from foreign securities. These taxes may be reduced or eliminated under the terms of an applicable U.S. income tax treaty. The anticipated extent of the Portfolio's investment in foreign securities is such that it is not expected that a Holder that is a RIC which invests its assets in the Portfolio will be eligible to pass through to its shareholders foreign taxes paid by the Portfolio and allocated to the Holder, so that shareholders of such RIC will not be entitled to foreign tax credits or deductions for foreign taxes paid by the Portfolio and allocated to the RIC.

Transactions in foreign currencies, foreign currency-denominated debt securities and certain foreign currency options, futures contracts, and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. Equity investments by the Portfolio in passive foreign investment companies ("PFICs") could subject Holders of the Portfolio to adverse U.S. federal income tax consequences and other charges on certain distributions from such companies and on disposition of investments in such companies; however, the tax consequences of such investments may be mitigated in certain cases if the Portfolio makes an election to mark such investments to market annually or treat the PFICs as "qualified electing funds." There can be no assurance that the Portfolio will make such an election. Treasury Regulations have recently been proposed that, if and when finalized, would generally require Holders, rather than the Portfolio, to make such elections with respect to PFICs in which the Portfolio invests. There can be no assurance that the Portfolio will be able to provide to Holders information adequate to make and maintain such elections. Certain uses of foreign currency and foreign currency derivatives such as options, futures, forward contracts and swaps and investments by the Portfolio in the stock of certain PFICs may be limited, or an election with respect to PFICs may be made, if available, in order to enable a Holder that is a RIC to preserve its qualification as a RIC or to reduce the imposition of tax on the Holders.

An entity that is treated as a partnership under the Code, such as the Portfolio, is generally treated as a partnership under state and local tax laws, but certain states may have different entity classification criteria and may therefore reach a different conclusion. Entities that are classified as partnerships are not treated as separate taxable entities under most state and local tax laws, and the income of a partnership is considered to be income of partners both in timing and in character. The laws of the various state and local taxing authorities vary with respect to the status of a partnership interest under state and local tax laws, and each Holder is advised to consult its own tax advisor.

The foregoing discussion does not address the special tax rules applicable to certain classes of investors, such as tax-exempt entities, foreign investors, insurance companies and financial institutions. Investors should consult their own tax advisors with respect to special tax rules that may apply in their particular situations, as well as the state, local or foreign tax consequences of investing in the Portfolio. It is not possible to predict at this time whether or to what extent any changes in the Code or interpretations thereof will occur. Prospective investors should consult their own tax advisors regarding pending and proposed legislation and other changes.
