Calvert Mid-Cap Fund

One Post Office Square

Boston, Massachusetts 02109

August 12, 2025

Dear Shareholder:

We are sending this combined information statement/prospectus to you because you are a shareholder of Calvert Mid-Cap Fund (the "Acquired Fund" or the "Fund"). On June 10, 2025, the Board of Directors (the "Board") of the Acquired Fund approved a proposal by Calvert Research and Management ("CRM"), the investment adviser to the Acquired Fund, to reorganize the Acquired Fund with and into (the "Merger") Calvert Small/Mid-Cap Fund (the "Acquiring Fund" together with the "Acquired Fund" the "Funds"). The Merger does not require shareholder approval and is expected to be tax free for federal income tax purposes. It is expected that the Merger will be completed on or about September 15, 2025.

**WE ARE NOT ASKING YOU FOR A PROXY AND YOU ARE REQUESTED NOT TO SEND US A PROXY.** 

The Funds have similar investment objectives, policies, restrictions, and risks. The Acquired Fund has an investment objective to seek to provide long-term capital appreciation by investing primarily in mid-cap stocks, and the Acquired Fund normally invests at least 80% of its net assets, including any borrowings for investment purposes, in common stocks of mid-capitalization companies. The Acquiring Fund's investment objective is to provide growth of capital, and under normal market conditions, the Acquiring Fund invests at least 80% of its net assets, including any borrowings for investment purposes, in common stocks of small- to mid-capitalization companies. Both Funds are managed by CRM and have the same portfolio management team. The management fees of the Acquiring Fund are lower than the management fees of the Acquired Fund, and the total annual operating expenses of the Acquiring Fund are expected to be lower than the current total annual operating expenses of the Acquired Fund following completion of the Merger. Because the Funds have the same portfolio managers, similar investment objectives, policies, restrictions, and risks, and for other reasons as discussed more fully in the enclosed information statement/prospectus, CRM and the Board believe the Funds are appropriate merger partners. CRM and the Board of the Acquired Fund further believe that the Merger is in the best interests of the Acquired Fund.

The Board has carefully reviewed the terms of the Merger and determined unanimously to approve the Merger. Details regarding the terms of the Merger, and its potential benefits and costs to shareholders, are discussed in the enclosed information statement/prospectus, which we urge you to review carefully.

**CALVERT MANAGEMENT SERIES** 

**Calvert Small/Mid-Cap Fund** 

**INFORMATION STATEMENT/PROSPECTUS** 

August 12, 2025

**The responses to the questions that follow provide a brief overview of the reorganization (the "Merger") of Calvert Mid-Cap Fund (the "Acquired Fund") with and into Calvert Small/Mid-Cap Fund (the "Acquiring Fund" and together with the Acquired Fund, the "Funds" and each a "Fund"). We encourage you to read the full text of the enclosed information statement/prospectus for a complete description of the Merger.** 

**WE ARE NOT ASKING YOU FOR A PROXY AND YOU ARE REQUESTED NOT TO SEND US A PROXY** 

**Q: Why are you sending me this information?** 

As a shareholder of the Acquired Fund, your investment will be impacted by the Merger. On the date of the Merger, your shares of the Acquired Fund will, in effect, be exchanged for shares of the Acquiring Fund of the same class and with an equal aggregate net asset value. Therefore, as a result of the Merger, you and the other shareholders of the Acquired Fund will become shareholders of the Acquiring Fund. This combined information statement/prospectus ("Information Statement/Prospectus") provides you with information about the Merger and the Acquiring Fund.

**Q: What is the Merger?** 

The Merger will involve your Fund, the Acquired Fund, transferring all of its assets and liabilities to another fund, the Acquiring Fund, in exchange for shares of that Acquiring Fund. The Acquired Fund will then liquidate and distribute the shares of the Acquiring Fund to its shareholders. Once the Merger is completed, shareholders of the Acquired Fund will hold shares of the Acquiring Fund, as follows:

---

|:---|:---|
| &nbsp;&nbsp;&nbsp; **Acquired Fund**<br>**(Acquisition of the assets of:)**<br>| **Acquiring Fund** |
| &nbsp;&nbsp;&nbsp; Calvert Mid-Cap Fund<br>| Calvert Small/Mid-Cap Fund<br>|

| &nbsp;&nbsp;&nbsp; Calvert Mid-Cap Fund | Class I | Þ | Class I | Calvert Small/Mid-Cap Fund |

---

You, as a holder of shares of the Acquired Fund, will receive shares of the corresponding Acquiring Fund with the same aggregate net asset value as the aggregate net asset value of your Acquired Fund shares at the time of the Merger. The Merger is expected to be completed on or about September 15, 2025.

We encourage you to read the full text of the enclosed Information Statement/Prospectus to obtain a more detailed understanding of the issues relating to the Merger.

------

##### [**Table of Contents**](#toc)
**Q: Why is the Merger being pursued?** 

Calvert Research and Management ("CRM"), the investment adviser to the Funds, has recommended the Merger because it believes that the Merger is in the best interests of the Acquired Fund. CRM believes that the Acquired Fund's long-term viability would be improved if it is merged with the Acquiring Fund, as it believes that the Merger will better position the Fund for growth. It is expected that the expenses borne by the Acquired Fund's shareholders will decrease following the Merger, as both the gross and net expenses (after giving effect to fee waivers and/or expense reimbursement) of each share class of the Acquiring Fund are expected to be the same or lower after the Merger than those of the Acquired Fund (after giving effect to fee waivers and/or expense reimbursements). The Merger would result in Acquired Fund shareholders becoming shareholders of the Acquiring Fund, which has similar investment objectives, investment strategies, risks and restrictions to the Acquired Fund, and is managed by CRM with the same portfolio management team.

**Q: Are the Funds' investment objectives, investment policies, principal investment strategies, and principal risks similar?** 

Yes. The Acquired Fund and Acquiring Fund have similar investment objectives, policies, restrictions, and principal risks. The Acquired Fund has an investment objective to seek to provide long-term capital appreciation by investing primarily in mid-cap stocks, and the Acquired Fund normally invests at least 80% of its net assets, including any borrowings for investment purposes, in common stocks of mid-capitalization companies. The Acquiring Fund's investment objective is to provide growth of capital, and under normal market conditions, the Acquiring Fund invests at least 80% of its net assets, including any borrowings for investment purposes, in common stocks of small- to mid-capitalization companies. Both the Acquired Fund and the Acquiring Fund are subject to the Calvert Principles for Responsible Investing, which provide a framework for considering environmental, social and governance factors. Following the Merger, the Acquiring Fund will continue to be subject to the Calvert Principles for Responsible Investing.

Please see the "Comparison of Investment Objectives," "Comparison of Principal Investment Strategies," and "Comparison of Principal Risks" sections of the Information Statement/Prospectus for more detail.

**Q: Will the investment adviser to my Fund change as a result of the Merger?** 

No. CRM is the investment adviser to both the Acquired Fund and the Acquiring Fund. CRM will continue to serve as the investment adviser to the Acquiring Fund following the Merger.

In addition, the portfolio managers of each Fund are the same, and the current portfolio managers of the Acquired Fund will continue to serve as portfolio managers of the Acquiring Fund, following the Merger.

**Q: Will there be any changes to the options or services associated with my account as a result of the Merger?** 

Account-level features and options such as dividend distributions, automatic investment plans, and systematic withdrawals will automatically carry over from accounts in the Acquired Fund to accounts in the Acquiring Fund.

The Merger is not expected to result in any change or diminution in the level of services or resources that CRM, as applicable, has provided historically to each Fund, and CRM believes it will provide the Acquiring Fund, following the Merger, with continued strong administrative, compliance, and marketing and sales support.

**Q: Will there be changes to the Acquired Fund's portfolio in connection with the Merger?** 

CRM expects that approximately 40.5% of the Acquired Fund's portfolio will need to be repositioned prior to completion of the Merger. The Acquired Fund's portfolio repositioning may result in the Acquired Fund realizing capital gains. Based on market values and net assets as of April 30, 2025, realized capital gains as a result of the repositioning are estimated at $20.4 million (9.9% of net assets). Shareholders of the Acquired Fund generally will be taxed on such capital gain distributions. It is also estimated that such portfolio repositioning will result in brokerage and other transaction costs, including trading taxes, of approximately $17,296.

For a more detailed discussion of the federal income tax consequences of the Merger, please see "Summary—U.S. Federal Income Tax Consequences."

------

##### [**Table of Contents**](#toc)
**Q: Are there costs or U.S. federal income tax consequences of the Merger?** 

The Funds will not bear the direct expenses of the Merger. CRM and/or its affiliates will bear all ordinary one-time direct expenses in connection with the Merger. Such expenses are estimated to be approximately $388,800 to $438,800 in the aggregate for legal costs, audit-related costs, accounting and tax services. The Funds will bear any brokerage or other portfolio transaction costs as a result of any repositioning of Fund holdings, as well as any taxes, litigation costs, or other extraordinary or unforeseen expenses. The Merger is expected to be tax-free for U.S. federal income tax purposes. Accordingly, it is expected that Acquired Fund shareholders will not, and the Acquired Fund generally will not, recognize gain or loss as a direct result of the Merger, as described in more detail in the section of the Information Statement/Prospectus entitled "ADDITIONAL INFORMATION ABOUT THE MERGER—Tax Status of the Merger." At any time prior to the consummation of the Merger, a shareholder may redeem shares, which generally will result in the recognition of gain or loss to such shareholder for U.S. federal income tax purposes. Because the Merger will end the tax year of the Acquired Fund, it will accelerate distributions to shareholders from the Acquired Fund for its short tax year ending on the date of the Merger. Those tax year-end distributions will be taxable and will include any capital gains resulting from portfolio turnover prior to consummation of the Merger that were not previously distributed.

**Q: Will there be any changes to my fees and expenses as a result of the Merger?** 

It is expected that, following the Merger, both the gross and net expenses of each share class of the Acquiring Fund will be the same or lower than those of the Acquired Fund, and the net expenses (after giving effect to fee waivers and/or expense reimbursements) borne by Acquired Fund shareholders as shareholders of the Acquiring Fund will be lower than the net expenses they currently bear, as described in detail in the "Comparison of Fees and Expenses" section below.

**Q: When will the Merger happen?** 

The Merger is expected to be completed on or about September 15, 2025.

**Q: Will you need my vote to approve the Merger?** 

No. The Merger does not require shareholder approval. We are not asking you for a proxy and you are requested not to send us a proxy.

Pursuant to applicable rules under the Investment Company Act of 1940, as amended ("1940 Act"), approval by shareholders of an acquired fund would be required if the merger would result in a change that, in a context other than a merger, would require shareholder approval under the 1940 Act. These factors generally include increased distribution fees as a result of the merger, materially different advisory contracts, different directors/trustees, or materially different fundamental investment policies as between the acquired and acquiring funds. Shareholder approval of this Merger is not required because none of the factors requiring a shareholder vote are present.

**Q: Has the Board approved the Merger?** 

Yes. The Board determined that the Merger would be in the best interests of the Acquired Fund and the Acquiring Fund and that the interests of existing shareholders of each Fund would not be diluted as a result of the Merger. The Board, including a majority of the independent directors or trustees of each Fund who are not "interested persons" (within the meaning of the 1940 Act) of the Acquired Fund and the Acquiring Fund, voted to approve the Merger.

See the attached Information Statement/Prospectus for the complete list of factors considered by the Board in approving the Merger.

**Q: Whom should I call if I have questions?** 

If you have questions about the proposal described in the Information Statement/Prospectus, please call 1-800-368-2745.

You should carefully read the entire Information Statement/Prospectus and the appendices, as they contain details that are not included in this summary.

**How the Merger Will Work** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Acquired Fund will transfer all of its assets to the Acquiring Fund in exchange for shares of the Acquiring
Fund ("Merger Shares") and the assumption by the Acquiring Fund of all of the Acquired Fund's liabilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Acquiring Fund will issue Merger Shares with an aggregate net asset value equal to the aggregate value of the
assets that it receives from the Acquired Fund, less the liabilities it assumes from the Acquired Fund. Merger Shares of the applicable class of the Acquiring Fund will be distributed to the corresponding class of shareholders of the Acquired Fund
in proportion to their holdings of such class of such Acquired Fund as set forth below.

| &nbsp;&nbsp;&nbsp; Calvert Mid-Cap Fund | Class I | Þ | Class I | Calvert Small/Mid-Cap Fund |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Holders of each class of shares of the Acquired Fund will receive Merger Shares with the same aggregate net asset
value as the aggregate net asset value of their shares at the time of the Merger.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• CRM will bear the direct expenses of the Merger, other than the excluded expenses as described in the Merger
Agreement. Estimated reorganization costs are set forth in "Costs of the Merger."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Merger is expected to be tax-free for U.S. federal income tax
purposes. Accordingly, it is expected that Acquired Fund shareholders will not, and the Acquired Fund generally will not, recognize gain or loss as a direct result of the Merger, as described in more detail in the section of the Information
Statement/Prospectus entitled "ADDITIONAL INFORMATION ABOUT THE MERGER—Tax Status of the Merger."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• As part of the Merger of your Acquired Fund, systematic transactions (such as bank authorizations and systematic
payouts) currently set up for your Acquired Fund account may be transferred to your new Acquiring Fund account. Please contact your financial intermediary for additional details.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• No shareholders of the Acquired Fund will pay any sales charge in connection with acquiring Merger Shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• After the Merger is completed, Acquired Fund shareholders will be shareholders of the Acquiring Fund, and the
Acquired Fund will be dissolved.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Acquiring Fund will be the accounting and performance survivor of the Merger.

**Costs of the Merger** 

The Funds will not bear the direct expenses of the Merger. CRM and/or its affiliates will bear all ordinary one-time direct expenses in connection with the Merger, except as described below. The one-time direct expenses of the Merger that will be borne by CRM and/or its affiliates, including legal, audit-related, accounting, and tax services, are estimated to be approximately $388,800 to $438,800 in the aggregate. It is currently expected that a portion of the Acquired Fund's portfolio assets (approximately 40.5%) will be sold prior to the consummation of the Merger in order to more closely align the Acquired Fund's portfolio with that of the Acquired Fund. It is estimated that such portfolio repositioning will result in brokerage and other transaction costs, including trading taxes, of approximately $17,296 for the Acquired Fund. The Funds, and not CRM, will bear any taxes, brokerage and other transaction costs, litigation costs or other extraordinary or unforeseen expenses. Notwithstanding any of the foregoing, costs and expenses will in any event be paid by the party directly incurring them if and to the extent that the payment by another party of such costs and expenses would result in the disqualification of such party as a "regulated investment company" within the meaning of Sections 851 and 852 of the Internal Revenue Code of 1986 (the "Code") or in failure of the Merger to be treated as a reorganization described in Section 368(a)(1) of the Code.

**U.S. Federal Income Tax Consequences** 

The Merger is expected to be tax-free for U.S. federal income tax purposes and will not take place unless the Acquired Fund and the Acquiring Fund receive a satisfactory opinion of tax counsel substantially to the effect that the Merger will be tax-free, as described in more detail in the section entitled "ADDITIONAL INFORMATION ABOUT THE MERGER — Tax Status of the Merger." Accordingly, subject to the limited exceptions described in that section, no gain or loss is expected to be recognized for U.S. federal income tax purposes by the Acquired Fund or its shareholders as a direct result of its Merger. At any time prior to the Merger, a shareholder may redeem shares of the Acquired Fund. Any such redemption would likely result in the recognition of gain or loss by the shareholder for U.S. federal income tax purposes. If a shareholder holds Acquired Fund shares in a non-taxable account, distributions and redemption proceeds with respect to those shares will not be taxable to the shareholder if those amounts remain in the non-taxable account.

The Acquired Fund shareholders' aggregate tax basis in the Merger Shares is expected to carry over from the shareholders' Acquired Fund shares, and the Acquired Fund shareholders' holding period in the Merger Shares is expected to include the shareholders' holding period in the Acquired Fund shares.

A portion of the portfolio assets of the Acquired Fund are expected to be sold in connection with the Merger. The actual tax impact of such sales will depend on the difference between the price at which such portfolio assets are sold and the Acquired Fund's tax basis in such assets. Any net capital gains recognized in these sales will be distributed to the Acquired Fund's shareholders as capital gain dividends (to the extent of net realized long-term capital gains over net-realized short-term capital losses) and/or ordinary dividends (to the extent of net realized short-term capital gains over net realized long-term capital losses) during or with respect to the year of sale, and such distributions will be taxable to shareholders.

Prior to the closing of the Merger, the Acquired Fund will, and the Acquiring Fund may, declare a distribution to shareholders which, together with all previous distributions, will have the effect of distributing to shareholders all of the Fund's investment company taxable income (computed without regard to the deduction for dividends paid), net tax-exempt income, if any, and net realized capital gains, if any, through the closing of the Merger. These distributions will be taxable to shareholders and such distributions by the Acquired Fund will include any capital gains resulting from portfolio turnover prior to the Merger.

For more information about the U.S. federal income tax consequences of the Merger, see the section entitled "ADDITIONAL INFORMATION ABOUT THE MERGER—Tax Status of the Merger."

**Fees and Expenses** 

It is expected that the expenses borne by the Acquired Fund's shareholders will decrease following the Merger, as both the gross and net expenses (after giving effect to fee waivers and/or expense reimbursement) of each share class of the Acquiring Fund are expected to be the same or lower after the Merger than those of the Acquired Fund (after giving effect to fee waivers and/or expense reimbursements). Management fees of the Acquiring Fund are lower than those of the Acquired Fund.

Annual fund operating expense ratios for the Acquired Fund are based on expenses incurred during its fiscal year ended September 30, 2024. Annual fund operating expense ratios for the Acquiring Fund are based on expenses incurred during the period ended June 30, 2025.

*Pro forma* fees and expenses, which are the estimated fees and expenses of the Acquiring Fund after giving effect to the Merger, assume the Merger occurred on June 30, 2025.

In general, a fund's annual operating expense ratios will increase as the fund's assets decrease and will decrease as the fund's assets increase. Accordingly, each Fund's annual operating expense ratios, if adjusted based on net assets as of the date of this Information Statement/Prospectus, could be higher or lower than those shown in the tables below. In addition, future increases or decreases in the Acquiring Fund's net assets following the Merger could result in annual fund operating expenses that are higher or lower than those shown in the tables below. As of June 30, 2025, the total net assets of the Acquired Fund were $211,712,631 and the total net assets of the Acquiring Fund were $29,798,670. The fees and expenses below exclude one-time direct expenses of the Merger, which will be paid by CRM and/or its affiliates. Additional information regarding the costs of the Merger is set forth under "Costs of the Merger" above.

The tables below describe the fees and expenses that you may pay if you buy, hold, and sell shares of the Funds. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) CRM has agreed to reimburse the Acquired Fund's expenses to the extent that Total Annual Fund Operating
Expenses exceed 1.18% for Class A shares, 1.93% for Class C shares, and 0.93% for Class I shares. This expense reimbursement will continue through February 1, 2026. Any amendment to or termination of this reimbursement would
require approval of the Board of Directors. The expense reimbursement relates to ordinary operating expenses only and does not include expenses such as: brokerage commissions, acquired fund fees and expenses of unaffiliated funds, borrowing costs
(including costs of any acquired funds), taxes, or litigation expenses. Amounts reimbursed may be recouped by CRM during the same fiscal year to the extent actual expenses are less than any contractual expense cap in place during such year. Pursuant
to this arrangement, CRM may recoup from the

##### [**Table of Contents**](#toc)
Acquired Fund any reimbursed expenses during the same fiscal year if such recoupment does not cause the Acquired Fund's Total Annual Operating Expenses after such recoupment to exceed (i) the expense limit in effect at the time of reimbursement; or (ii) the expense limit in effect at the time of recoupment. <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) CRM has agreed to reimburse the Acquiring Fund's expenses to the extent that Total Annual Fund Operating
Expenses exceed 1.14% for Class A shares, 1.89% for Class C shares, and 0.89% for Class I shares. This expense reimbursement will remain in effect through September 15, 2028. Any amendment to or termination of this reimbursement
would require approval of the Board of Trustees. The expense reimbursement relates to ordinary operating expenses only and does not include expenses such as: brokerage commissions, acquired fund fees and expenses of unaffiliated funds, borrowing
costs (including borrowing costs of any acquired funds), taxes, or litigation expenses. Amounts reimbursed may be recouped by the administrator during the same fiscal year to the extent actual expenses are less than any contractual expense cap
during in place such year. Pursuant to this arrangement, CRM may recoup from the Acquiring Fund any reimbursed expenses during the same fiscal year if such recoupment does not cause the Acquiring Fund's Total Annual Operating Expenses after
such recoupment to exceed (i) the expense limit in effect at the time of reimbursement; or (ii) the expense limit in effect at the time of recoupment.

**Expense Examples:** The Examples are intended to help you compare the costs of investing in shares of the Acquired Fund or the Acquiring Fund with the costs of investing in other mutual funds. The Examples assume that (i) you invest $10,000 in the relevant Fund for the time periods indicated and then hold or redeem all your shares <u>at the end of those periods</u>; (ii) your investment has a 5% return each year; and (iii) operating expenses are the lesser of total annual fund operating expenses or the applicable expense limitation. Although your actual costs may be higher or lower, based on these assumptions your costs would be as follows:

**Investment Objectives, Policies, Strategies, Principal Risks** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**a.** **Overview of Comparison of the Acquired Fund and the Acquiring Fund** 

The Acquired Fund and the Acquiring Fund:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Have the same investment manager and the same portfolio management team;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Have similar investment objectives;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Have similar principal investment strategies and risks;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Have substantially similar fundamental investment restrictions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Have identical valuation policies;

------

##### [**Table of Contents**](#toc)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Have identical policies for buying and selling shares and exchange rights. Please see Appendix D for a
description of these policies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Are both subject to the Calvert Principles for Responsible Investment; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Are structured as series of an open-end management investment company.
The Acquiring Fund is organized as a series of a Massachusetts business trust. The Acquired Fund is organized as a series of a Maryland corporation. Please see "ADDITIONAL INFORMATION ABOUT THE MERGER – Comparison of Shareholder
Rights" for additional information.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**b.** **Comparison of Investment Objectives** 

The investment objectives of the Acquired Fund and the Acquiring Fund are similar, and are as follows:

**Acquired Fund.** To seek to provide long-term capital appreciation by investing primarily in mid-cap stocks.

**Acquiring Fund.** To provide growth of capital.

The Acquired Fund's and the Acquiring Fund's investment objective may be changed by the Board of Directors or Board of Trustees, respectively (together the "Board")<sup>1</sup> without shareholder approval.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**c.** **Comparison of Principal Investment Strategies** 

The investment strategies of the Acquired and the Acquiring Fund are similar. The Acquired Fund normally invests at least 80% of its net assets, including borrowings for investment purposes, in common stocks of mid-capitalization companies. Under normal market conditions, the Acquiring Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in common stocks of small- to mid-capitalization companies. While the Funds 80% investment policies are different, both Funds invest primarily in the common stock of mid-cap companies and also invest in small-cap companies. The Funds share the same primary broad based benchmark, which is the Russell 3000<sup>®</sup> Index. For both the Acquired Fund and Acquiring Fund, investment decisions are made primarily on the basis of fundamental research and consideration of the responsible investing criteria (see the "Responsible Investing" section in each Fund's investment strategy, reproduced below, and the Calvert Principles for Responsible Investment, as set forth in both Acquired Fund's and Acquiring Fund's prospectuses). The portfolio managers of both Funds also employ a disciplined valuation framework in pursuit of attractive risk adjusted returns. With respect to both Funds, they seek to manage investment risk by maintaining broad issuer and industry diversification among the Fund's holdings, and by utilizing fundamental analysis of risk/return characteristics in securities selection. The following reproduces the principal investment strategies of the Acquired Fund and the Acquiring Fund, as disclosed in each Fund's prospectus, dated February 1, 2025 and May 1, 2025, respectively:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**d.** **Comparison of Fundamental Investment Policies** 

The fundamental investment restrictions of each of the Acquired Fund and Acquiring Fund are substantially similar, with minor differences in wording, and there are no material differences in how these restrictions are applied to the Funds. Accordingly, the management of the combined Fund in accordance with the fundamental investment policies of the Acquiring Fund following the Merger will not result in any material differences between the way the Funds are currently managed and the way the Acquiring Fund will be managed following the Merger. A "fundamental" investment policy is one that may not be changed without a shareholder vote. The following chart compares the fundamental investment policies of the Acquired Fund and the Acquiring Fund:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**e.** **Comparison of Principal Risks** 

The principal risks associated with investments in the Acquiring Fund and the Acquired Fund are substantially similar because the Funds have similar investment objectives and similar principal investment strategies. The following chart identifies the principal risks associated with each Fund as described in the summary prospectus for each Fund. The actual risks of investing in the Funds depend on the securities the Acquired Fund holds, and assuming the completion of the Merger, the Acquiring Fund will hold, and on market conditions, both of which will change over time.

As shown above, the Acquired Fund and the Acquiring Fund have substantially similar principal risks. The Acquired Fund shares each of its principal risks with the Acquiring Fund, with the exception of Securities Lending Risk, which is not a principal risk of the Acquiring Fund. The Acquiring Fund prospectus discloses the following principal risks, which are not disclosed as principal risks of the Acquired Fund: Growth Risk; Financials Sector Risk; Emerging Markets Investment Risk; and ETF Risk.

------

##### [**Table of Contents**](#toc)
The principal risks for the Acquiring Fund, as described in the Acquiring Fund's summary prospectus, are described below. The significance of any specific risk to an investment in the Acquiring Fund will vary over time, depending on the composition of the Fund's portfolio, market conditions, and other factors. All references to a "Fund" in the principal risks below refers to the Acquiring Fund unless otherwise noted.

<u>Market Risk.</u> The value of investments held by the Fund may increase or decrease in response to social, economic, political, financial, public health crises or other disruptive events (whether real, expected or perceived) in the U.S. and global markets and include events such as war, natural disasters, epidemics and pandemics, terrorism, conflicts and social unrest. These events may negatively impact broad segments of businesses and populations and may exacerbate pre-existing risks to the Fund. The frequency and magnitude of resulting changes in the value of the Fund's investments cannot be predicted. Certain securities and other investments held by the Fund may experience increased volatility, illiquidity, or other potentially adverse effects in reaction to changing market conditions. Monetary and/or fiscal actions taken by U.S. or foreign governments to stimulate or stabilize the global economy may not be effective and could lead to high market volatility.

<u>Equity Securities Risk.</u> The value of equity securities and related instruments may decline in response to adverse changes in the economy or the economic outlook; deterioration in investor sentiment; interest rate, currency, and commodity price fluctuations; adverse geopolitical, social or environmental developments; issuer and sector-specific considerations; unexpected trading activity among retail investors; or other factors. Market conditions may affect certain types of stocks to a greater extent than other types of stocks. If the stock market declines in value, the value of the Fund's equity securities will also likely decline. Although prices can rebound, there is no assurance that values will return to previous levels.

<u>Smaller and Mid-Sized Company Risk.</u> The stocks of smaller and mid-sized companies are generally subject to greater price fluctuations, limited liquidity, higher transaction costs and higher investment risk than the stocks of larger, more established companies. Such companies may have limited product lines, markets or financial resources, may be dependent on a limited management group, and may lack substantial capital reserves or an established performance record. There may be generally less publicly available information about such companies than for larger, more established companies. Stocks of these companies frequently have lower trading volumes making them more volatile and potentially less liquid and more difficult to value.

<u>Responsible Investing Risk.</u> Investing primarily in responsible investments carries the risk that, under certain market conditions, the Fund's performance may be impacted. The application of responsible investment criteria may affect the Fund's exposure to certain sectors or types of investments, and may impact the Fund's relative investment performance depending on whether such sectors or investments are in or out of favor in the market. An investment's ESG performance or the investment adviser's assessment of such performance may change over time, which could cause the Fund to temporarily hold securities that do not comply with the Fund's responsible investment criteria. In evaluating an investment, the investment adviser is dependent upon information and data that may be incomplete, inaccurate or unavailable, which could adversely affect the analysis of the ESG factors relevant to a particular investment. Successful application of the Fund's responsible investment strategy will depend on the investment adviser's skill in properly identifying and analyzing material ESG issues.

<u>Growth Risk.</u> Because the Fund normally invests primarily in stocks of growth companies, it is subject to the risk of underperforming the overall stock market during periods in which stocks of such companies are out of favor and generate lower returns than the market as a whole.

<u>Focused Investment Risk.</u> To the extent the Fund has substantial investments in a relatively small number of securities or issuers, or a particular market, industry, group of industries, country, region, group of countries, asset class or sector, the Fund's performance will be more susceptible to any single economic, market, political, or regulatory occurrence affecting those particular securities or issuers or that particular market, industry, group of industries, country, region, group of countries, assets class, or sector than a fund that invests more broadly.

------

##### [**Table of Contents**](#toc)
<u>Financials Sector Risk.</u> To the extent the Fund invests a substantial portion of its assets in the financials sector, factors that have an adverse impact on this sector may have a disproportionate impact on the Fund's performance. The financials sector can be affected by global and local economic conditions, such as the levels and liquidity of the global and local financial and asset markets, the absolute and relative level and volatility of interest rates and equity prices, investor sentiment, inflation, and the availability and cost of credit. The enactment of new legislation or regulations, as well as changes in interpretation and enforcement of current laws, may affect the manner of operations and profitability of the financials sector.

<u>Industrials Sector Risk.</u> To the extent a Fund invests a substantial portion of its assets in the industrials sector, factors that have an adverse impact on this sector may have a disproportionate impact on the Fund's performance. The industrials sector can be affected by government regulation, world events, supply and demand for specific products and services, commodity prices, exchange rates and economic conditions, technological developments, and liabilities for environmental damage, product liability claims, and general civil liabilities.

<u>Foreign Investment Risk.</u> Foreign investments can be adversely affected by political, economic and market developments abroad, including the imposition of economic and other sanctions by the United States or another country against a particular country or countries, organizations, entities and/or individuals. There may be less publicly available information about foreign issuers because they may not be subject to reporting practices, requirements or regulations comparable to those to which United States companies are subject. Adverse changes in investment regulations, capital requirements or exchange controls could adversely affect the value of the Fund's investments. Foreign markets may be smaller, less liquid and more volatile than the major markets in the United States and, as a result, Fund share values may be more volatile. Trading in foreign markets typically involves higher expense than trading in the United States. The Fund may have difficulties enforcing its legal or contractual rights in a foreign country. Depositary receipts are subject to many of the risks associated with investing directly in foreign instruments, including the political and economic risks of the underlying issuer's country and, in the case of depositary receipts traded on foreign markets, currency risk.

<u>Emerging Markets Investment Risk.</u> Investment markets within emerging market countries are typically smaller, less liquid, less developed and more volatile than those in more developed markets like the United States, and may be focused in certain sectors. Emerging market securities often involve greater risks than developed market securities. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets.

<u>Currency Risk.</u> Exchange rates for currencies fluctuate daily. The value of foreign investments may be affected favorably or unfavorably by changes in currency exchange rates in relation to the U.S. dollar. Currency markets generally are not as regulated as securities markets and currency transactions are subject to settlement, custodial and other operational risks.

<u>ETF Risk.</u> ETFs are subject to the risks of investing in the underlying securities or other investments. ETF shares may trade at a premium or discount to net asset value and are subject to secondary market trading risks. In addition, the Fund will bear a pro rata portion of the operating expenses of an ETF in which it invests.

<u>Real Estate Risk.</u> Real estate investments are subject to risks associated with owning real estate, including declines in real estate values, increases in property taxes, fluctuations in interest rates, limited availability of mortgage financing, decreases in revenues from underlying real estate assets, declines in occupancy rates, changes in government regulations affecting zoning, land use, and rents, environmental liabilities, and risks related to the management skill and creditworthiness of the issuer. Companies in the real estate industry may also be subject to liabilities under environmental and hazardous waste laws, among others. REITs must satisfy specific requirements for favorable tax treatment and can involve unique risks in addition to the risks generally affecting the real estate industry. Changes in underlying real estate values may have an exaggerated effect to the extent that investments are concentrated in particular geographic regions or property types.

------

##### [**Table of Contents**](#toc)
<u>Liquidity Risk.</u> The Fund is exposed to liquidity risk when trading volume, lack of a market maker or trading partner, large position size, market conditions, or legal restrictions impair its ability to sell particular investments or to sell them at advantageous market prices. Consequently, the Fund may have to accept a lower price to sell an investment or continue to hold it or keep the position open, sell other investments to raise cash or abandon an investment opportunity, any of which could have a negative effect on the Fund's performance. These effects may be exacerbated during times of financial or political stress.

<u>Risks Associated with Active Management.</u> The success of the Fund's investment strategy depends on portfolio management's successful application of analytical skills and investment judgment. Active management involves subjective decisions and there is no guarantee that such decisions will produce the desired results or expected returns.

<u>General Fund Investing Risks.</u> The Fund is not a complete investment program and there is no guarantee that the Fund will achieve its investment objective. It is possible to lose money by investing in the Fund. The Fund is designed to be a long-term investment vehicle and is not suited for short-term trading. Investors in the Fund should have a long-term investment perspective and be able to tolerate potentially sharp declines in value. Purchase and redemption activities by Fund shareholders may impact the management of the Fund and its ability to achieve its investment objective(s). In addition, the redemption by one or more large shareholders or groups of shareholders of their holdings in the Fund could have an adverse impact on the remaining shareholders in the Fund. The Fund relies on various service providers, including the investment adviser and sub-adviser, if applicable, in its operations and is susceptible to operational, information security and related events (such as public health crises, cyber or hacking attacks) that may affect the service providers or the services that they provide to the Fund. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

**Performance** 

The following bar charts and tables provide some illustration of the risks of investing in the Funds by showing how each Fund's performance has varied for each full calendar year shown in the bar chart.

The returns in the bar chart 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 not necessarily an indication of how a Fund will perform in the future. The Funds' 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.calvert.com.

With respect to the Acquired Fund, CRM became the investment adviser to the Fund on December 31, 2016. Performance reflected prior to such date is that of the Acquired Fund's former investment adviser.

With respect to the Acquiring Fund, performance shown below for periods prior to September 15, 2023 is the performance of the Eaton Vance Special Equities Fund (the "Predecessor Fund") as a result of a reorganization of the Predecessor Fund into the Acquiring Fund on September 15, 2023 (the "2023 Merger"). As a result of the 2023 Merger, the Acquiring Fund was the accounting successor of the Predecessor Fund. The Predecessor Fund was managed using investment policies, objectives, guidelines, and restrictions that were substantially similar to those of the Fund. The Predecessor Fund did not follow the Calvert Principles and, accordingly, the performance of the Predecessor Fund may not be indicative of how the Acquiring Fund may have performed. Prior to the 2023 Merger, the Acquiring Fund had not yet commenced operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) The Fund's primary benchmark index was changed from the Russell Midcap<sup>®</sup> Index to the Russell 3000<sup>®</sup> Index effective May 1, 2024 to comply with the regulation that requires the Fund's primary
benchmark to represent the overall applicable market.

These returns reflect the maximum current sales charge for Class A (5.25%) and any applicable contingent deferred sales charge ("CDSC") for Class C. Effective November 5, 2020, Class C shares automatically convert to Class A shares eight years after purchase. The average annual total returns listed for Class C reflect conversion to Class A shares after eight years. Prior to November 5, 2020, Class C shares automatically converted to Class A shares ten years after purchase. Investors cannot invest directly in an Index.

After-tax returns are calculated using the highest historical individual U.S. 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 non-taxable entities. After-tax returns for other Classes of shares will vary from the after-tax returns presented for Class A 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 Before Taxes and/or Return After Taxes on Distributions for the same period because of losses realized on the sale of Fund shares.

**Fiscal Year** 

The fiscal year end of the Acquired Fund is September 30. The fiscal year end of the Acquiring Fund is December 31.

##### [**Table of Contents**](#toc)
**Portfolio Turnover** 

The Acquired Fund and the Acquiring Fund pay transaction costs, such as commissions, when the Fund buys and sells securities (or "turns over" the portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Funds' shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Funds' performance. During the most recent fiscal year ended September 30, 2024, the Acquired Fund's portfolio turnover rate was 26% of the average value of its portfolio. During the most recent fiscal year ended December 31, 2024, the Acquiring Fund's portfolio turnover rate was 42% of the average value of its portfolio.

**Management of the Funds** 

CRM is the investment adviser to both the Acquired Fund and the Acquiring Fund and will continue to serve as the investment adviser to the Acquiring Fund, following the Merger.

Michael D. McLean and J. Griffith Nobel currently serve as portfolio managers to both the Acquired Fund and the Acquiring Fund and are expected to continue serving as portfolio mangers for the Acquiring Fund, following the Merger.

For more information on the Funds' service providers and portfolio managers, please see Appendix B and Appendix C.

**Distribution Arrangements** 

Shares of the Acquired Fund and the Acquiring Fund are sold on a continuous basis by Eaton Vance Distributors, Inc. ("EVD"), the Funds' principal underwriter. EVD will continue to serve as the Acquiring Fund's principal underwriter following the Merger.

As a result of the Merger, shareholders of each class of the Acquired Fund will receive a proportional distribution of shares of a corresponding class of the Acquiring Fund.

You will not be charged any sales charges, commissions, or transactions fees in the Merger. Any other investment or redemption will be subject to any applicable sales charge. After the Merger is completed, any contingent deferred sales charge ("CDSC") on the redemption of shares of the Acquiring Fund will be calculated from the date of original purchase of the Acquired Fund shares.

**Purchase and Sale of Fund Shares** 

The Funds operate under the same purchase, redemption, and exchange procedures. You may purchase, redeem, or exchange Fund shares on any business day, which is any day the New York Stock Exchange is open for business. You may purchase, redeem, or exchange Fund shares either through your financial intermediary or (except for purchases of Class C shares by accounts with no specified financial intermediary) directly from the Fund. The minimum initial purchase or exchange into the Funds is $1,000 for Class A and Class C and $1,000,000 for Class I. There is no minimum for subsequent investments.

For additional information about the purchase, redemption, exchange and valuation policies of the Funds, see "Additional Information About Acquiring Fund Shares" in Appendix D.

**Payments to Broker-Dealers and Other Financial Intermediaries** 

If you purchase a Fund's shares through a broker-dealer or other financial intermediary (such as a bank) (collectively, "financial intermediaries"), the Fund, its principal underwriter, and/or its affiliates may pay the financial intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the financial intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

**Tax Information** 

Each of the Acquired Fund and the Acquiring Fund has elected or intends to elect to be treated, and intends to qualify and be treated each year, as a regulated investment company (a "RIC") under Subchapter M of the Code

------

##### [**Table of Contents**](#toc)
for U.S. federal income tax purposes and expects to distribute net investment income and net realized capital gains, if any, to its shareholders. These distributions are taxable as ordinary income or capital gain to U.S. shareholders that are neither exempt from U.S. federal income tax nor investing through a tax-advantaged account such as a tax-qualified retirement plan.

**II.** **ADDITIONAL INFORMATION ABOUT THE MERGER** 

**Terms of the Merger** 

As stated above, the Merger Agreement, which provides for the reorganization of the Acquired Fund with and into the Acquiring Fund, was previously considered and approved by the Board. While shareholders are encouraged to review the Merger Agreement, which is included as Appendix A to this Information Statement/Prospectus, the following is a summary of certain terms of the Merger Agreement and is qualified in its entirety by the full text of the Merger Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Merger is expected to be completed on or about September 15, 2025, or such other date as the parties may
agree (the "Merger Date"), subject to satisfaction of any other conditions to closing. However, the Merger may happen at any time agreed to by the Acquired Fund and the Acquiring Fund. No approval of the shareholders of the Acquired Fund
is required in connection with the Merger Agreement or the transactions contemplated thereby.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Acquired Fund will transfer all of its assets to the Acquiring Fund, and, in exchange, the Acquiring Fund
will assume all of the Acquired Fund's liabilities and will issue Merger Shares to the Acquired Fund. The value of the Acquired Fund's assets, as well as the number of Merger Shares to be issued to the Acquired Fund, will be determined in
accordance with the Merger Agreement. On or soon after the Merger Date, the Acquired Fund will liquidate, and shareholders of each class of the Acquired Fund will receive a proportional distribution of Merger Shares of a corresponding class of the
Acquiring Fund. As a result, shareholders of the Acquired Fund will become shareholders of the Acquiring Fund. No shareholders of the Acquired Fund will pay any sales charges, commissions, or transaction fees in connection with the Merger.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The net asset value of each Acquired Fund and the corresponding Acquiring Fund will be computed as of the close
of regular trading on the New York Stock Exchange on or about September 12, 2025, after the declaration and payment of any dividend on that date. The net asset value of the Acquiring Fund shares will be computed in the manner set forth in the
Acquiring Fund's then-current registration statement. In determining the value of the securities transferred by the Acquired Fund to the Acquiring Fund, such assets shall be priced in accordance with the policies and procedures described in the
applicable Acquiring Fund's then-current registration statement.

**Conditions to Closing of the Merger** 

The completion of the Merger is subject to certain conditions described in the Agreement, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A registration statement on Form N-14 relating to the Merger will have
been filed with the SEC and become effective.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Funds will have received all permits and other authorizations necessary, if any, under state securities laws
to consummate the transactions contemplated by the Merger Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Acquired Fund and the Acquiring Fund will have received an opinion of tax counsel substantially to the effect
that, as described in more detail in the section entitled "Tax Status of the Merger," the shareholders of the Acquired Fund will not recognize gain or loss for U.S. federal income tax purposes upon the exchange of their Acquired Fund
shares for the Merger Shares of the Acquiring Fund in connection with the Merger and the Acquired Fund generally will not recognize gain or loss as a direct result of the Merger.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On the Merger Date, the Merger Shares will be duly authorized, duly and validly issued and outstanding, and fully
paid and non-assessable by Calvert Management Series, will conform in all substantial respects

------

##### [**Table of Contents**](#toc)
to the description thereof contained in this Information Statement/Prospectus, will be duly registered under the Securities Act of 1933, as amended, and will be offered and sold in compliance with all applicable state securities laws.

**Termination of the Merger Agreement** 

The Merger Agreement may be terminated by any party thereto by providing notice to the other parties, if any of the representations, warranties, or conditions specified in the Merger Agreement have not been performed or do not exist on or before a specified date. In the event of termination of the Merger Agreement, neither party to the Merger Agreement (nor its officers, Trustees/Directors, or shareholders) shall have any liability to the other.

**Tax Status of the Merger** 

The Merger is intended to qualify for U.S. federal income tax purposes as a tax-free reorganization under Section 368(a) of the Code. As a condition to the closing of the Merger, the Acquired Fund and the Acquiring Fund will receive an opinion from Ropes & Gray LLP substantially to the effect that, on the basis of existing provisions of the Code, U.S. Treasury regulations promulgated thereunder, current administrative rules and court decisions, for U.S. federal income tax purposes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. The transfer of all of the assets of the Acquired Fund (the "acquired assets") in exchange for Merger
Shares and the assumption by the Acquiring Fund of all liabilities of the Acquired Fund (the "assumed liabilities") followed by the distribution of the Merger Shares pro rata to the Acquired Fund shareholders will constitute a
"reorganization" within the meaning of Section 368(a) of the Code and the Acquiring Fund and the Acquired Fund will each be a "party to a reorganization" within the meaning of Section 368(b) of the Code.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii. Under Section 1032 of the Code, no gain or loss will be recognized by the Acquiring Fund upon the receipt
of the acquired assets solely in exchange for the Merger Shares and the assumption by the Acquiring Fund of the assumed liabilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii. Under Sections 361 and 357 of the Code, no gain or loss will be recognized by the Acquired Fund in connection
with the transfer of the acquired assets to the Acquiring Fund in exchange for the Merger Shares and the assumption by the Acquiring Fund of the assumed liabilities, or with respect to the distribution of the Merger Shares to Acquired Fund
shareholders, except for (A) any gain or loss recognized on (1) "section 1256 contracts" as defined in Section 1256(b) of the Code or (2) stock in a "passive foreign investment company" as defined in
Section 1297(a) of the Code, and (B) any other gain or loss that may be required to be recognized (1) as a result of the closing of the tax year of the Acquired Fund, (2) upon the termination of a position, or (3) upon the
transfer of an asset regardless of whether such a transfer would otherwise be a nontaxable transaction under the Code.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iv. Under Section 354 of the Code, no gain or loss will be recognized by the Acquired Fund shareholders upon
their receipt of the Merger Shares solely in exchange for Acquired Fund shares (including fractional shares to which they may be entitled) in the Merger.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;v. Under Section 358 of the Code, the aggregate tax basis of the Merger Shares received by each Acquired Fund
shareholder (including fractional shares to which they may be entitled) will be the same as the aggregate tax basis of the Acquired Fund shares held by such shareholder immediately prior to the exchange, and under Section 1223(1) of the Code
the holding period of the Merger Shares received by each Acquired Fund shareholder (including fractional shares to which they may be entitled) will include the period during which the Acquired Fund shares exchanged therefor were held or treated for
federal income tax purposes as held by such shareholder (provided such shareholder held the Acquired Fund shares as capital assets).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;vi. Under Section 362(b) of the Code, the tax basis of the acquired assets acquired by the Acquiring Fund will
be the same as the tax basis of such assets to the Acquired Fund immediately prior to the Merger, increased by any gain or decreased by any loss required to be recognized as described in (iii) above, and under Section 1223(2) of the Code
the holding period of the acquired assets in the hands of the

------

##### [**Table of Contents**](#toc)
Acquiring Fund will include the period during which those assets were held or treated for federal income tax purposes as held by the Acquired Fund, other than certain assets with respect to which gain or loss is required to be recognized as described in (iii) above.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;vii. The Acquiring Fund will succeed to and take into account the items of the Acquired Fund described in
Section 381(c) of the Code, subject to the conditions and limitations specified in Sections 381, 382, 383, and 384 of the Code and the Treasury Regulations thereunder.

The opinion will be based on assumptions and representations made by the officers of the Acquired Fund and the Acquiring Fund and will also be based on customary assumptions. It is possible that the IRS or a court could disagree with Ropes & Gray LLP's opinion, which therefore cannot be free from doubt.

Opinions of counsel are not binding upon the IRS or the courts. If the Merger were consummated but did not qualify as a tax-free reorganization under the Code, a shareholder of the Acquired Fund would recognize a taxable gain or loss for U.S. federal income tax purposes equal to the difference between its tax basis in its Acquired Fund shares and the fair market value of the Merger Shares it received. Shareholders of the Acquired Fund should consult their tax advisers regarding the effect, if any, of the Merger in light of their individual circumstances.

It is currently expected that a portion of the Acquired Fund's portfolio assets (approximately 40.5%) will be sold prior to the consummation of the Merger in order to more closely align the Acquired Fund's portfolio with that of the Acquired Fund, as described in the table below.

The Acquired Fund's portfolio repositioning may result in the Acquired Fund realizing capital gains, as described in the table below. Based on market values and net assets as of April 30, 2025, realized capital gains as a result of the repositioning are estimated at $20.4 million (9.9% of net assets). Shareholders of the Acquired Fund generally will be taxed on such capital gain distributions. It is also estimated that such portfolio repositioning will result in brokerage and other transaction costs, including trading taxes, of approximately $17,296 for the Acquired Fund.

| &nbsp;&nbsp;&nbsp; 40.5% <br>| $20.4M  | $3.69  |

---

Prior to the closing of the Merger, the Acquired Fund will, and the Acquiring Fund may, declare a distribution to shareholders which, together with all previous distributions, will have the effect of distributing to shareholders all of the Fund's investment company taxable income (computed without regard to the deduction for dividends paid), net tax-exempt income, if any, and net realized capital gains, if any, through the closing of the Merger. These distributions will be taxable to shareholders and such distributions by the Acquired Fund will include any capital gains resulting from portfolio turnover prior to the Merger.

Even if the Merger qualifies for tax-free treatment, the Funds' ability to carry forward capital losses and to use them to offset future gains may be limited as a result of the Merger. First, a Fund's "pre-acquisition losses" (including capital loss carryforwards, net current-year capital losses, and unrealized losses that exceed certain thresholds) may become unavailable to offset gains of the combined Fund to the extent such pre-acquisition losses exceed an annual limitation amount. Second, one Fund's pre-acquisition losses cannot be used to offset gains in another Fund that are unrealized ("built in") at the time of the Merger and that exceed certain thresholds ("non-de minimis built-in gains") for five tax years. Third, the Acquired Fund's loss carryforwards, as limited under the previous two rules, are permitted to offset only that portion of the gains of the Acquiring Fund for the taxable year of the Merger that is equal to the portion of the Acquiring Fund's taxable year that follows the date of the Merger (prorated according to number of days). Therefore, in certain circumstances, shareholders of a Fund may pay taxes sooner, or pay more taxes, than they would have had the Merger not occurred.

In addition, if the Merger qualifies as tax-free, the combined Fund will have tax attributes that reflect a blending of the tax attributes of each Fund at the time of the Merger (including as affected by the rules described above). Therefore, the shareholders of the Acquired Fund will receive a proportionate share of any unrealized gains in the

------

##### [**Table of Contents**](#toc)
combined Fund's assets, as well as any taxable income or gains realized by the Acquiring Fund but not distributed to its shareholders prior to the Merger, when such income or gains are eventually distributed by the Acquiring Fund. As a result, shareholders of the Acquired Fund may receive a greater amount of taxable distributions than they would have had the Merger not occurred. In addition, any pre-acquisition losses of the Acquired Fund (whether realized or unrealized) remaining after the operation of the limitation rules described above will become available to offset capital gains realized by the combined Fund after the Merger and thus may reduce subsequent capital gain distributions to a broader group of shareholders than would have been the case absent such Merger, such that the benefit of those losses to Acquired Fund shareholders may be further reduced relative to what the benefit would have been had the Merger not occurred.

The tax-free nature of the Merger and the realized and unrealized gains and losses of each Fund at the time of the Merger will determine the extent to which the combining Funds' respective losses, both realized and unrealized, will be available to reduce gains realized by the combined Fund following the Merger, and consequently the extent to which the combined Fund may be required to distribute gains to its shareholders earlier or in greater amounts than would have been the case absent the Merger. The effect of the rules described above will depend on the relative sizes of, and the losses and gains (both realized and unrealized) in, each Fund at the time of the Merger and thus cannot be calculated precisely prior to the Merger.

**Comparison of Shareholder Rights** 

Each Fund is an open-end management investment company. The Acquiring Fund is organized as a series of a Massachusetts business trust under the laws of the Commonwealth of Massachusetts (the "Acquiring Fund Trust") by an Agreement and Declaration of Trust (the "Declaration"). The Acquired Fund is organized as a series of a Maryland corporation, under the laws of the State of Maryland (the "Acquired Fund Corporation") pursuant to articles of incorporation (the "Articles"). Each Fund is governed by its Declaration or Articles, as the case may be, and their respective bylaws. The Funds' business and affairs are managed under the supervision of the Board. The Funds are each subject to the federal securities laws, including the 1940 Act, and the rules and regulations promulgated by the SEC thereunder.

The following is a comparison of certain important provisions of the Declaration, the Articles and bylaws of the Funds but is not a complete description thereof. Following the Merger, the Acquired Fund shareholder will become a shareholder of the Acquiring Fund and will have the rights set forth in Calvert Management Series' Declaration and bylaws. A copy of the Acquired Fund's Articles and the Acquiring Fund's Declaration is on file with the Maryland Secretary of State and the Secretary of the Commonwealth of Massachusetts, respectively.

*Shares*. For both the Acquired Fund Corporation and Acquiring Fund Trust, the Board may require a shareholder to redeem such shareholder's shares if at any time the total investment in the account does not have a minimum dollar value determined from time to time by the Trustees.

*Quorum*. For the Acquired Fund Corporation, the quorum requirement for transaction of business at a shareholder meeting is the presence in person or by proxy of the holders of one third (1/3) of the outstanding shares of the relevant series entitled to vote . For the Acquiring Fund Trust, the quorum requirement for transaction of business at a shareholder meeting is the presence in person or by proxy of the holders of twenty-five percent (25%) of the outstanding shares of the relevant series entitled to vote, unless a larger quorum is required by law.

*Removal of Trustees/Directors*. Trustees of the Acquiring Fund Trust may be removed with or without cause by (i) the affirmative vote of holders of two-thirds (2/3) of the outstanding shares of the Acquiring Fund Trust or (ii) the affirmative vote of not less than two-thirds of the remaining Trustees prior to such removal. Directors of the Acquired Fund Corporation may be removed with or without cause by (i) the affirmative vote of holders of a majority of the outstanding shares of the Acquired Fund Corporation.

*Amendment of Governing Instruments*. For the Acquired Fund Corporation, the Corporation reserves the right at any time to alter, amend, or repeal any provisions contained in the Articles, including any amendment that alters the contract rights of any outstanding stock, at any time in the manner now or hereafter prescribed by the laws of the state of Maryland. For the Acquiring Fund Trust, the Declaration may be amended at any time by an

------

##### [**Table of Contents**](#toc)
instrument in writing signed by a majority of the then Trustees when authorized to do so by a vote of a majority of the votes cast entitled to vote on such matter. The Trustees of the Acquiring Fund Trust may also amend the Declaration without the vote or consent of shareholders to change the name of the Trust or any series, if they deem it necessary to conform it to applicable federal or state laws or regulations, or to make such other changes (such as reclassifying series or classes of shares or restructuring the Trust) provided such changes do not have a materially adverse effect on the financial interests of shareholders. For both the Acquired Fund Corporation and the Acquiring Fund Trust, the bylaws may be amended, supplemented, amended and restated, or repealed, in whole or in part, by a majority of the Trustees or Directors, as applicable then in office at any meeting of the Trustees or Directors, as applicable, or by one or more writings signed by such a majority.

*Mergers and Reorganizations*. The Acquiring Fund Trust's Declaration provides that the Trustees, with the approval of the holders of a majority of the outstanding shares, may merge, consolidate, or sell and convey the assets of the Trust including its goodwill to another trust or corporation organized under the laws of any state of the United States for an adequate consideration. In contrast, the Acquired Fund Corporation's Articles and bylaws are silent with respect to the applicable voting standard for mergers and reorganizations.

*Termination*. The Acquiring Fund Trust's Declaration provides that, subject to a "Majority Shareholder Vote," as defined in the Declaration, Trustees may at any time sell and convert into money all the assets of the Trust, and upon making provision for the payment of all outstanding obligations, taxes and other liabilities, accrued or contingent, of the Trust, the Trustees shall distribute the remaining assets of the Trust ratably among the holders of the outstanding Shares. In contrast, Acquired Fund Corporation's Articles and bylaws are silent with respect to the applicable voting standard for terminations, except that any determination made by or pursuant to the direction of the Board to liquidate the investments of the Corporation in an orderly fashion will be final and conclusive as long as it is made in good faith. The Acquired Fund may be terminated in accordance with the laws of the State of Maryland. The Acquired Fund's bylaws provide that in the event of the liquidation of a particular series or class of such series, the stockholders of the series or class that is being liquidated shall be entitled to receive, as a class, when and as declared by the Board, the excess of the assets associated with that series or class over the liabilities of that series or class. The holders of shares of any particular series or class of such series shall not be entitled thereby to any distribution upon liquidation of any other series or class. The assets so distributable to the stockholders of a series or class of such series shall be distributed among such stockholders in proportion to the number of shares of that series or class of such series held by them and recorded on the books of the Acquired Fund Corporation, except that such distribution shall appropriately reflect all liabilities of that series charged to any class thereof.

*Forum Selection*. For the Acquiring Fund Trust, any claim (whether direct, derivative or otherwise) of any nature against or on behalf of the Trust, any series or class, the Trustees or officers of the Trust, or the investment adviser, shall be brought exclusively in the United States District Court for the District of Massachusetts, or to the extent such court does not have jurisdiction than such actions and/or claims, shall be brought in the Superior Court of Suffolk County for the Commonwealth of Massachusetts. In contrast, Acquired Fund Corporation's Articles and bylaws are silent with respect to the matter of forum selection.

**Reasons for the Merger and Board Deliberations** 

The Merger was reviewed by the Acquired Fund's Board at a meeting held on June 10-11, 2025, with the advice and assistance of independent legal counsel to the Board's independent directors. Information regarding the Acquired Fund's Board and its governance structure can be found in the Acquired Fund's SAI. In connection with its review, the Acquired Fund's Board requested and reviewed written information regarding the Merger, met with representatives of the Acquired Fund's portfolio management team and senior management of CRM, and met privately with independent legal counsel to the Acquired Fund Board's independent directors. CRM's presentation to the Board included information regarding reliance on Rule 17a-8(a)(3) under the 1940 Act such that no shareholder approval of the Merger is required.

After the Acquired Fund's Board reviewed, evaluated, and discussed the materials, analyses, and information provided to it that it considered relevant to its deliberations, at its meeting held on June 10-11, 2025, the Acquired Fund's Board, including the independent directors, approved the Merger of the Acquired Fund into the Acquiring

------

##### [**Table of Contents**](#toc)
Fund. The Acquired Fund's Board, including the independent directors, also determined at that time that participation by the Acquired Fund in the Merger was in the best interests of the Acquired Fund and that the interests of existing shareholders of the Acquired Fund would not be diluted as a result of the Merger.

In reaching the decision to approve the Merger, the Acquired Fund's Board considered a number of factors, including, among others, in no order of priority, with respect to the Acquired Fund:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. the potential benefits of the Merger to the shareholders of the Acquired Fund, including the potential for
economies of scale, growth prospects, and long-term viability by becoming shareholders of a larger combined fund that has similar investment objectives and policies and lower expenses (before and after giving effect to fee waivers and/or expense
reimbursements);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. continuity of management in that (i) both the Acquired Fund and Acquiring Fund are managed by CRM and CRM
is expected to provide the same nature, scope, and quality of management services to the Acquiring Fund as the Acquired Fund has enjoyed; (ii) like the Acquired Fund, the Acquiring Fund is subject to the Calvert Principles; and (iii) the
existing portfolio managers of the Acquired Fund are expected to serve as portfolio managers of the Acquiring Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. the lower overall management fees of the Acquiring Fund compared to the Acquired Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. the operating expenses that shareholders of each class of shares of the Acquired Fund are expected to
experience as shareholders of the corresponding Acquiring Fund after the Merger relative to the operating expenses currently borne by such shareholders, including that it is expected that the gross expenses of the Acquiring Fund will be lower than
those of the Acquired Fund and the net expenses (after giving effect to fee waivers and/or expense reimbursements) borne by Acquired Fund shareholders after the Merger will be lower than the expenses they currently bear due to a lower expense cap
for the Acquiring Fund in the expense limitation agreements that will remain in place until at least September 15, 2028;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. the historical performance of the Acquired Fund compared to the Acquiring Fund, including that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. the Class I Shares of the Acquiring Fund outperformed the Class I Shares of the Acquired Fund,
relative to their respective performance benchmarks (the Russell 2500 Index in the case of the Acquiring Fund and the Russell Midcap Index in the case of the Acquired Fund), for each of the 1-, 3-, and 5-year periods ended April 30, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. The Class I Shares of the Acquiring Fund ranked higher than the Class I Shares of the Acquired Fund,
within their respective Morningstar categories, for each of the 3-, and 5-year periods ended April 30, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. the current assets under management of both the Acquired Fund and Acquiring Fund, the Acquired Fund's
recent challenges with relative outflows, and the expectation that the Merger may provide shareholders with a better opportunity to achieve more substantial scale and growth in a fund that will provide exposure to a similar portfolio of securities
as the Acquired Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. the substantially similar distribution platforms and channels being available to the Acquiring Fund compared to
the Acquired Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. continuity of administration and other services in that (i) CRM provides administration services to each
of the Funds and will continue to provide administration services to the Acquiring Fund of approximately the same nature and quality; and (ii) DST Asset Manager Solutions, Inc. ("DST") serves as transfer agent to each of the Funds and
will continue to provide substantially similar services to the Acquiring Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. the compliance program of the Acquiring Fund will operate in the same manner as the compliance program for the
Acquired Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. the anticipated tax-free nature of the exchange of shares in the
Merger, and other expected U.S. federal income tax consequences of the Merger (see "ADDITIONAL INFORMATION ABOUT THE MERGER—Tax Status of the Merger");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11. the comparability of the share class structure of, and services provided to, the Acquired Fund and the
Acquiring Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12. the structure of the Merger, whereby shareholders of each class of shares of the Acquired Fund will receive
shares of the corresponding class of the Acquiring Fund at net asset value, not subject to any

------

##### [**Table of Contents**](#toc)
sales charges, in a tax-free reorganization. Because the Acquired Fund shareholders will receive shares of the Acquiring Fund with the same aggregate net asset value as their Acquired Fund shares at the time of the Merger, the Merger will not dilute the interests of the shareholders of the Acquired Fund; <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13. The Funds will bear any brokerage or other portfolio transaction costs as a result of any repositioning of Fund
holdings, as well as any taxes, litigation costs, or other extraordinary or unforeseen expenses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;14. that shareholders of the Acquired Fund will have the opportunity to redeem their shares from the Acquired Fund
should they not wish to become shareholders of the Acquiring Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;15. that management considered other possible options for the Acquired Fund, including the possible liquidation of
the Acquired Fund, but does not believe that such options would be in the best interests of shareholders; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;16. CRM's representation that the Merger is not expected to result in any diminution in the level or quality
of services that CRM provides.

In its deliberations, the Acquired Fund Board did not identify any single factor that was paramount or controlling and individual Board members may have attributed different weights to various factors.

its shareholders of record the Acquiring Fund Shares received by the Acquired Fund pursuant to Section 2.1. In addition, as soon as is reasonably practicable after the Closing (the "Liquidation Date"), the Acquired Fund will

7. <u>Conditions Precedent to Closing</u> 

The obligations of the parties hereto shall be conditioned on the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.1 <u>Representations and Warranties</u>. The representations and warranties of the parties made herein will be
true and correct as of the date of this Agreement and on the Closing Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.2 <u>Tax-Free Reorganization</u>. It is the intention of the parties
that the Reorganization will qualify as a reorganization within the meaning of Section 368(a)(l) of the Code. None of the parties to the Reorganization shall take any action or cause any action to be taken (including, without limitation the
filing of any tax return) that is inconsistent with such treatment or is reasonably likely to result in the failure of such Reorganization to qualify as a reorganization within the meaning of Section 368(a)(l) of the Code.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.3 <u>Favorable Tax Opinion of Ropes</u> <u>& Gray, LLP</u>. The Acquired Fund and the
Acquiring Fund shall have received a favorable opinion of Ropes & Gray LLP dated on the Closing Date (which opinion will be subject to certain qualifications) reasonably satisfactory to both parties substantially to the effect that, on the
basis of the existing provisions of the Code, Treasury regulations promulgated thereunder, current administrative rules, and court decisions, generally for federal income tax purposes, with respect to the Reorganization of the Acquired Fund with and
into the Acquiring Fund:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. The acquisition by the Acquiring Fund of the Assets of the Acquired Fund in exchange for the Acquiring
Fund's assumption of the Liabilities of the Acquired Fund and the Acquiring Fund Shares, followed by the distribution by the Acquired Fund of such Acquiring Fund Shares to the shareholders of the Acquired Fund in exchange for their shares of
the Acquired Fund, all as provided in Section 2 hereof, will constitute a reorganization within the meaning of Section 368(a) of the Code, and the Acquired Fund and the Acquiring Fund will each be "a party to a reorganization"
within the meaning of Section 368(b) of the Code.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. No gain or loss will be recognized by the Acquired Fund (i) upon the transfer of its Assets to the
Acquiring Fund solely in exchange for the Acquiring Fund Shares and the assumption by the Acquiring Fund of the Liabilities of the Acquired Fund or (ii) upon the distribution of the Acquiring Fund Shares by the Acquired Fund to its shareholders
in liquidation, as contemplated in Section 2 hereof, except for (A) any gain or loss recognized on (1) "section 1256 contracts" as defined in Section 1256(b) of the Code

------

##### [**Table of Contents**](#toc)
or (2) stock in a "passive foreign investment company" as defined in Section 1297(a) of the Code, and (B) any other gain or loss that may be required to be recognized (1) as a result of the closing of the tax year of the Acquired Fund, (2) upon the termination of a position, or (3) upon the transfer of an Asset regardless of whether such a transfer would otherwise be a nontaxable transaction under the Cod**e**. <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. No gain or loss will be recognized by the Acquiring Fund upon the receipt of the Assets of the Acquired Fund
solely in exchange for the assumption of the Liabilities of the Acquired Fund and the Acquiring Fund Shares as contemplated in Section 2 hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d. The tax basis of the Assets of the Acquired Fund acquired by the Acquiring Fund will be the same as the tax
basis of such Assets in the hands of the Acquired Fund immediately prior to the Reorganization, increased by any gain or decreased by any loss required to be recognized as described in (b) above.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e. The holding periods of the Assets of the Acquired Fund in the hands of the Acquiring Fund will include the
periods during which such Assets were held or treated for federal income tax purposes as held by the Acquired Fund, other than certain Assets with respect to which gain or loss is required to be recognized as described in (b) above.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;f. No gain or loss will be recognized by Acquired Fund shareholders upon the exchange of all of their Acquired
Fund shares for the Acquiring Fund Shares (including fractional shares to which they may be entitled).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;g. The aggregate tax basis of the Acquiring Fund Shares to be received by each shareholder of the Acquired Fund
(including fractional shares to which they may be entitled) will be the same as the aggregate tax basis of Acquired Fund shares exchanged therefor.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;h. An Acquired Fund shareholder's holding period for the Acquiring Fund Shares (including fractional
shares to which they may be entitled) to be received will include the period during which Acquired Fund shares exchanged therefor were held or treated for federal income tax purposes as held by such shareholder, provided that the shareholder held
Acquired Fund shares as a capital asset on the date of the Reorganization.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. The Acquiring Fund will succeed to and take into account the items of the Acquired Fund described in

**APPENDIX B** 

**MANAGEMENT OF THE ACQUIRING FUND** 

The Acquiring Fund's investment adviser is Calvert Research and Management ("CRM"). CRM is a registered investment adviser and has an office at 2050 M Street NW, Washington, DC 20036. CRM is an indirect, wholly owned subsidiary of Morgan Stanley.

Morgan Stanley (NYSE: MS), whose principal offices are at 1585 Broadway, New York, New York 10036, is a preeminent global financial services firm engaged in securities trading and brokerage activities, as well as providing investment banking, research and analysis, financing and financial advisory services. As of March 31, 2025, Morgan Stanley's asset management operations had aggregate assets under management or supervision of approximately $1.6 trillion.

The Acquiring Fund's Form N-CSR filing covering the fiscal period ended June 30 provides information regarding the basis for the Trustees' approval of the Acquiring Fund's investment advisory agreement.

Under its investment advisory agreement with the Fund, CRM receives a monthly advisory fee as follows:

---

| | |
|:---|:---|
| Average Daily Net Assets for the Month | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Annual Fee Rate |
|  Up to $500 million | 0.505% |
|  $500 million but less than $1 billion | 0.480% |
|  $1 billion but less than $2.5 billion | 0.455% |
|  $2.5 billion but less than $5 billion | 0.435% |
|  $5 billion and over | 0.420% |

---

For the fiscal year ended December 31, 2024, the effective annual rate of advisory fee paid was 0.505% of average daily net assets.

The Fund is managed by Michael D. McLean and J. Griffith Noble (since inception), Managing Directors of Morgan Stanley and Vice Presidents of CRM. Mr. McLean and Mr. Noble have both been employees of the Morgan Stanley organization for more than five years and currently manage other funds. Prior to the inception of the Acquiring Fund, Messrs. McLean and Noble each managed the Predecessor Fund since January 2015.

The SAI provides additional information about each portfolio manager's compensation, other accounts managed by each portfolio manager, and each portfolio manager's ownership of Acquiring Fund shares.

CRM serves as administrator of the Fund, providing the Fund with administrative services and related office facilities. In return, each Class of the Fund is authorized to pay CRM a monthly administrative fee equal to 0.12% annually of average daily net assets. For the fiscal year ended December 31, 2024, the administrative fees paid by the Fund (as a percentage of daily net assets) were 0.12% for each share class.<sup>1</sup>

Eaton Vance Management ("Eaton Vance") provides sub-transfer agency and related services to Calvert mutual funds pursuant to a Sub-Transfer Agency Support Services Agreement. For its services under the agreement, Eaton Vance receives an aggregate fee from such funds equal to its actual expenses incurred in performing such services.

<sup>1</sup> Each share class of the Acquired Fund is authorized to pay CRM a monthly administrative fee equal to 0.12% annually of average daily net assets. For the fiscal year ended September 30, 2024, the administrative fee paid to CRM by each class of the Acquired Fund was 0.12% of average daily net assets.

**APPENDIX D** 

**ADDITIONAL INFORMATION ABOUT ACQUIRING FUND SHARES** 

**Valuing Shares** 

You may buy or sell (redeem) shares of the Fund at the NAV next determined for the class after receipt of your order in good order, plus any applicable sales charge. The Fund's NAV is determined as of the close of the New York Stock Exchange ("NYSE") (normally 4:00 p.m. Eastern Time) on each day that the NYSE is open for business (typically Monday through Friday) (the "Pricing Time"). The Fund is closed for business and will not issue a NAV on the following business holidays and any other business day that the NYSE is closed: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Juneteenth National Independence Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. On holidays or other days when the NYSE is closed, the NAV is generally not calculated and the Fund generally does not transact purchase or redemption requests. However, on those days, the value of the Fund's assets may be affected to the extent that the Fund holds foreign securities that trade on foreign markets that are open. In addition, trading of securities that are primarily listed on foreign exchanges may take place on weekends and other days when the Fund does not price its interests or transact purchase or redemption requests.

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 Fund 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 its investment adviser believes there generally remains an adequate market to obtain reliable and accurate market quotations. If market quotations, official closing prices, or information furnished by a pricing service are not readily available or, in the investment adviser's opinion, are deemed unreliable for a security, then that security will be fair valued in good faith by the investment adviser in accordance with applicable fair value pricing policies and in accordance with applicable law. The Fund may elect to remain open and price its shares on days when the NYSE is closed but the primary securities markets on which the Fund's securities trade remain open. To the extent, if any, that the Fund invests in securities primarily listed on foreign exchanges, the value of the Fund's portfolio securities may change on days when you will not be able to purchase or sell your shares. When purchasing or redeeming Fund shares through a financial intermediary, your financial intermediary must receive your order by the close of regular trading on the NYSE in order for the purchase price or the redemption price to be based on that day's net asset value per share. It is the financial intermediary's responsibility to transmit orders promptly. The Fund may accept purchase and redemption orders as of the time of their receipt by certain financial intermediaries (or their designated intermediaries).

The Board has adopted procedures for valuing investments (the "Procedures") and has delegated to the investment adviser, as valuation designee, the daily valuation of such investments. Pursuant to the Procedures, securities and other investments held by the Fund for which market quotations are readily available are generally valued at market value. Exchange-listed investments (including certain derivatives) are normally valued at last sale or closing prices. Exchange-traded options are valued at the mean of the bid and asked prices at valuation time as reported by the Options Price Reporting Authority for U.S. listed options, or by the relevant exchange or board of trade for non-U.S. listed options. Non-exchange traded derivatives are normally valued on the basis of quotes obtained from brokers and dealers or independent pricing services. Most loans and other debt obligations are valued using prices supplied by one or more pricing services.

Pursuant to the Procedures, if market quotations are not readily available (or otherwise not reliable) for a particular investment, the fair value of the investment will be determined by the investment adviser, as valuation designee. A market quotation is readily available only when that quotation is a quoted price (unadjusted) in active markets for identical investments that the Fund can access at the measurement date, provided that a quotation will not be readily available if it is not reliable. As such, the Fund will use fair value pricing if, for example, market prices or a pricing service's prices (as applicable) are unavailable or deemed unreliable, or if events occur after the close of a securities market (usually a foreign market) and before portfolio assets are valued that cause or are

------

##### [**Table of Contents**](#toc)
likely to cause a market quotation to be unavailable or unreliable, such as corporate actions, regulatory news, or natural disasters or governmental actions that may affect investments in a particular sector, country or region In addition, for foreign equity securities and total return swaps and futures contracts on foreign indices that meet certain criteria, the Board has approved the use of a fair value service that values such investments to reflect market trading that occurs after the close of the applicable foreign markets of comparable securities or other investments that have a strong correlation to the fair valued investments. An investment that is fair valued may be valued at a price higher or lower than (i) actual market quotations, (ii) the value determined by other funds using their own fair valuation procedures, or (iii) the price at which the investment could have been sold during the period in which fair valuation was used with respect to such investment to calculate the Fund's NAV. Because foreign investments held by the Fund, if any, may trade on days when Fund shares are not priced, the value of such investments, and thus the net asset value of the Fund's shares, can change on days when Fund shares cannot be redeemed or purchased. CRM has established a Valuation Committee that oversees the valuation of investments.

**Purchasing Shares** 

*Set forth below is information about the manner in which the Fund offers shares. A financial intermediary may offer Fund shares subject to variations in or elimination of the Fund sales charges ("variations"), provided such variations are described in this Prospectus. All variations described in Appendix D-1 are applied by, and the responsibility of, the identified financial intermediary. Sales charge variations may apply to purchases, sales, exchanges and reinvestments of Fund shares and a shareholder transacting in Fund shares through an intermediary identified on Appendix D-1 should read the terms and conditions of Appendix D-1 carefully. See also "Shareholder Account Features - 'Street Name' Accounts." For the variations applicable to shares offered through certain financial intermediaries, please see Appendix D-1 - Financial Intermediary Sales Charge Variations. A variation that is specific to a particular financial intermediary is not applicable to shares held directly with the Fund or through another intermediary.* 

You may purchase shares through your financial intermediary or by mailing an account application form to the transfer agent (see back cover for address). Purchase orders will be executed at the net asset value (plus any applicable sales charge) next determined after their receipt in proper form (meaning that the order is complete and contains all necessary information) by the Fund's transfer agent. The Fund's transfer agent or your financial intermediary must receive your purchase in proper form no later than the close of regular trading on the NYSE (normally 4:00 p.m. Eastern Time) for your purchase to be effected at that day's net asset value. If you purchase shares through a financial intermediary, that intermediary may charge you a fee for executing the purchase for you.

The Fund may suspend the sale of its shares at any time and any purchase order may be refused for any reason. The U.S. registered Calvert funds generally do not accept investments from residents of the European Union, the United Kingdom or Switzerland. The Calvert funds also do not accept investments from other non-U.S. residents, provided that a fund may accept investments from certain non-U.S. investors at the discretion of the principal underwriter. The Fund does not issue share certificates.

As used throughout this Prospectus, the term "employer sponsored retirement plan" includes the following: an employer sponsored pension or profit sharing plan that qualifies under section 401(a) of the Code (such as a 401(k) plan, money purchase pension, profit sharing and defined benefit plan); ERISA covered 403(b) plan; Taft-Hartley multi-employer plan; and non-qualified deferred compensation arrangements that operate in a similar manner to a qualified retirement plan (including 457 plans and executive deferred compensation arrangements). Individual Retirement Accounts ("IRAs") are not employer sponsored retirement plans for purposes of this definition.

**Class A and Class C Shares** 

Your initial investment must be at least $1,000. After your initial investment, additional investments may be made in any amount at any time by sending a check payable to the order of the Fund or the transfer agent directly to the transfer agent (see back cover for address). Please include your name and account number and the name of

------

##### [**Table of Contents**](#toc)
the Fund and Class of shares with each investment. The Fund no longer accepts direct purchases of Class C shares by accounts for which no broker-dealer or other financial intermediary is specified. Any direct purchase received by the Fund's transfer agent for Class C shares for such accounts will automatically be invested in Class A shares.

The minimum initial investment amount and Fund policy of redeeming accounts with low account balances are waived for bank automated investing accounts, certain group purchase plans (including employer sponsored retirement plans and proprietary fee-based programs sponsored by financial intermediaries) and for persons affiliated with CRM, its affiliates and certain Fund service providers (as described in the SAI). The investment adviser, in its sole discretion, may waive a minimum initial investment amount in certain cases.

**Class I Shares** 

Your initial investment must be at least $1,000,000, except as noted below. Class I shares are offered to clients of financial intermediaries who (i) charge such clients an ongoing fee for advisory, investment, consulting or similar services, or (ii) have entered into an agreement with the principal underwriter to offer Class I shares through a no-load network or platform. Such clients may include individuals, corporations, endowments, foundations and employer sponsored retirement plans. Class I shares may also be available through brokerage platforms of broker-dealer firms that have agreements with the Fund's principal underwriter to offer Class I shares solely when acting as an agent for the investor. An investor acquiring Class I shares through such platforms may be required to pay a commission and/or other forms of compensation to the broker. The Fund offers other share classes that have different fees and expenses. Class I shares also are offered to investment and institutional clients of CRM and its affiliates and certain persons affiliated with CRM. The investment adviser, in its sole discretion, may waive eligibility requirements in certain cases.

The Class I minimum initial investment is waived for persons affiliated with CRM, its affiliates and certain Fund service providers (as described in the SAI) and for the ReFlow Liquidity Program. The minimum initial investment also is waived for: (i) permitted exchanges; (ii) employer sponsored retirement plans; (iii) corporations, endowments and foundations with assets of at least $100 million; (iv) Class I shares purchased through the brokerage platforms described above; and (v) accounts of clients of financial intermediaries who (a) charge an ongoing fee for advisory, investment, consulting or similar services, or (b) have entered into an agreement with the principal underwriter to offer Class I shares through a no-load network or platform (in each case, as described above). The investment adviser, in its sole discretion, may waive a minimum initial investment amount in certain cases. Class I shares may be purchased through a financial intermediary or by requesting your bank to transmit immediately available funds (Federal Funds) by wire. To make an initial investment by wire, you must complete an account application and telephone Calvert Shareholder Services at 1-800-368-2745 to be assigned an account number. You may request an account application by calling 1-800-368-2745 Monday through Thursday, 9:00 a.m. to 5:30 p.m. (Eastern Time) and Friday, 9:00 a.m. to 5:00 p.m. (Eastern Time). Shareholder Services must be advised by telephone of each additional investment by wire.

**Subsequent Investments.** Subsequent investments of any amount may be made at any time, including through automatic investment each month or quarter from your bank account. You may make automatic investments of $50 or more each month or each quarter from your bank account provided such investments equal a minimum of $200 per year. You can establish bank automated investing on the account application or by providing written instructions to the Fund's transfer agent. Please call 1-800-368-2745 Monday through Thursday, 9:00 a.m. to 5:30 p.m. (Eastern Time) and Friday, 9:00 a.m. to 5:00 p.m. (Eastern Time) for further information.

You also may make additional investments by accessing your account via the Calvert website at www.calvert.com. The trade date of purchases made through the Internet from a pre-designated bank account will be the day the purchase is requested through the Calvert website (provided the request is on a business day and submitted no later than the close of regular trading on the NYSE). For more information about purchasing shares through the Internet, please call 1-800-368-2745 Monday through Thursday, 9:00 a.m. to 5:30 p.m. (Eastern Time) and Friday, 9:00 a.m. to 5:00 p.m. (Eastern Time).

**Inactive Accounts and Risk of Escheatment.** In accordance with state "unclaimed property" laws, your Fund shares may legally be considered abandoned and required to be transferred to the relevant state (also known as "escheatment") under various circumstances. These circumstances, which vary by state, can include inactivity (e.g., no owner-initiated contact for a certain period), returned mail (e.g., when mail sent to a shareholder is returned by the post office as undeliverable), uncashed checks or a combination of these. An incorrect address may cause a shareholder's account statements and other mailings to be returned to the Fund or your financial intermediary. Since states' statutory requirements regarding inactivity differ, it is important to regularly contact your financial intermediary or the Fund's transfer agent. The process described above, and the application of state escheatment laws, may vary by state and/or depending on how shareholders hold their shares in the Fund. Escheatment with respect to a retirement account is subject to a 10% federal withholding on the account.

It is your responsibility to ensure that you maintain a valid mailing address for your account, keep your account active by contacting your financial intermediary or the Fund's transfer agent (e.g., by mail or telephone), and promptly cash all checks for dividends, capital gains and redemptions. Neither the Fund nor the investment adviser(s) will be liable to shareholders or their representatives for good faith compliance with escheatment laws.

For more information, please see https://www.calvert.com/mutual-funds-and-unclaimed-property.php or please contact us at 1-800-368-2745.

**Restrictions on Excessive Trading and Market Timing.** The Fund is not intended for excessive trading or market timing. Market timers seek to profit by rapidly switching money into a fund when they expect the share price of the fund to rise and taking money out of the fund when they expect those prices to fall. By realizing profits through short-term trading, shareholders that engage in rapid purchases and sales (including exchanges, if permitted) of a fund's shares may dilute the value of shares held by long-term shareholders. Volatility resulting from excessive purchases and sales of fund shares, especially involving large dollar amounts, may disrupt efficient portfolio management. In particular, excessive purchases and sales of a fund's shares may cause a fund to have difficulty implementing its investment strategies, may force the fund to sell portfolio securities at inopportune times to raise cash or may cause increased expenses (such as increased brokerage costs, realization of taxable capital gains without attaining any investment advantage or increased administrative costs).

A fund that invests all or a portion of its assets in foreign securities may be susceptible to a time zone arbitrage strategy in which shareholders attempt to take advantage of fund share prices that may not reflect developments in a foreign securities market that occur after the close of such market but prior to the pricing of fund shares. In addition, a fund that invests in securities that are, among other things, thinly traded, traded infrequently or illiquid, is susceptible to the risk that the current market price for such securities may not accurately reflect current market values. A shareholder may seek to engage in short-term trading to take advantage of these pricing differences (commonly referred to as "price arbitrage"). The investment adviser is authorized to use the fair value of a security if prices are unavailable or are deemed unreliable (see "Valuing Shares"). The use of fair value pricing and the restrictions on excessive trading and market timing described below are intended to reduce a shareholder's ability to engage in price or time zone arbitrage to the detriment of the Fund. The Boards of the Calvert funds have adopted policies to discourage short-term trading and market timing and to seek to minimize their potentially detrimental effects (the "Policy"). Under the Policy, the Board has delegated to Eaton Vance, acting in its capacity as the Fund's sub-transfer agent, the responsibility to reject or cancel a purchase order, suspend or terminate an exchange privilege or terminate the ability of a shareholder to invest in the Calvert funds if Eaton Vance determines that a proposed transaction involves market timing or excessive trading that it believes is likely to be detrimental to the Fund.

Pursuant to the Policy, "two round-trips" completed by a Fund shareholder within 90 days through one or more accounts (the "Limitation") generally will be deemed to be indicative of market timing or trading excessively in fund shares. A "round trip" is defined as a purchase or exchange into a Fund followed or preceded by a redemption or exchange out of the Fund. Purchases and redemptions subject to the Limitation include those made by exchanging to or from another fund. Eaton Vance will evaluate transactions in Fund shares that violate the Limitation to determine whether they are likely to be detrimental to the Fund. In making such a determination, Eaton Vance may consider various factors, such as the amount, frequency and nature of trading activity. If such a

##### [**Table of Contents**](#toc)
determination is made, the Fund shareholder may be subject to restrictions on trading Fund shares, as described above. Eaton Vance uses reasonable efforts to detect market timing and excessive trading activity that is likely to be detrimental to the Fund, but it cannot ensure that it will be able to identify all such cases. Eaton Vance may also reject or cancel any purchase order (including an exchange) from a shareholder or group of shareholders for any other reason. In applying the Policy, and in particular when determining whether a transaction is likely to be detrimental to a Fund, Eaton Vance will be required to make judgments that are inherently subjective and will depend on the specific facts and circumstances. Such determinations will be made in a manner believed to be in the best interest of the Fund's shareholders. No Calvert fund has any arrangement to permit market timing.

The following Fund share transactions generally are exempt from the Policy because they generally do not raise market timing or excessive trading concerns:

---

| | |
|:---|:---|
| <sup>○</sup> | transactions (i) made pursuant to the Fund's systematic purchase, exchange or redemption plan, (ii) made as the result of automatic reinvestment of dividends or distributions, or (iii) initiated by the Fund (e.g., for transactions due to a failure to meet applicable account minimums);  |

---

---

| | |
|:---|:---|
| <sup>○</sup> | transactions made by participants in employer sponsored retirement plans involving (i) participant payroll or employer contributions or loan repayments, (ii) redemptions as part of plan terminations or at the direction of the plan, mandatory retirement distributions, or (iii) rollovers;  |

---

<sup>○</sup> transactions in shares of Calvert Ultra-Short Duration Income Fund; or

<sup>○</sup> investments in a fund by ReFlow in connection with the ReFlow liquidity program (if applicable to the Fund, the ReFlow liquidity program is described under "Investment Objectives & Principal Policies and Risks" above).

The following Fund share transactions generally are exempt from the Limitation; however, these transactions are subject to monitoring by Eaton Vance and may be subject to restrictions if deemed likely to be detrimental to the Fund:

<sup>○</sup> transactions made by model-based discretionary advisory accounts; or

<sup>○</sup> transactions made by funds that invest in the Fund as part of an asset reallocation in accordance with their investment policies or in response to Fund inflows and outflows.

It may be difficult for Eaton Vance to identify market timing or excessive trading in omnibus accounts traded through financial intermediaries. Eaton Vance has provided guidance to financial intermediaries (such as banks, broker-dealers, insurance companies and retirement administrators) concerning the application of the Policy to Fund shares held in omnibus accounts maintained and administered by such intermediaries, including guidance concerning situations where market timing or excessive trading is considered to be detrimental to the Fund. Eaton Vance may rely on a financial intermediary's policy to restrict market timing and excessive trading if it believes that policy is likely to prevent market timing that is likely to be detrimental to the Fund. Such policy may be more or less restrictive than the Policy. Although Eaton Vance reviews trading activity at the omnibus account level for activity that indicates potential market timing or excessive trading activity, Eaton Vance typically will not request or receive individual account data unless suspicious trading activity is identified. Eaton Vance generally relies on financial intermediaries to monitor trading activity in omnibus accounts in good faith in accordance with their own policies or the Policy. Eaton Vance cannot ensure that these financial intermediaries will in all cases apply the Policy or their own policies, as the case may be, to accounts under their control.

**Choosing a Share Class.** The Fund offers different classes of shares. The different classes of shares represent investments in the same portfolio of securities, but the classes are subject to different expenses and privileges, and will likely have different share prices due to differences in class expenses. A share class also may be subject to a sales charge. In choosing the class of shares that suits your investment needs, you should consider:

<sup>○</sup> how long you expect to own your shares;

<sup>○</sup> how much you intend to invest; and

---

| | |
|:---|:---|
| <sup>○</sup> | the total operating expenses associated with owning each class.  |

---

------

##### [**Table of Contents**](#toc)
Each investor's considerations are different. You should speak with your financial intermediary to help you decide which class of shares to purchase. Set forth below is a brief description of each class of shares offered by the Fund.

**Class A shares** are offered at net asset value plus a front-end sales charge of up to 5.25%. This charge is deducted from the amount you invest. The Class A sales charge is reduced for purchases of $50,000 or more. The sales charge applicable to your purchase may be reduced under the right of accumulation or a statement of intention, which are described in "Reducing or Eliminating Class A Sales Charges" under "Sales Charges" below. Some investors may be eligible to purchase Class A shares at net asset value under certain circumstances, which are also described below. Class A shares pay distribution and service fees equal to 0.25% annually of average daily net assets.

**Class C shares** are offered through financial intermediaries at net asset value with no front-end sales charge. If you sell your Class C shares within 12 months of purchase, you generally will be subject to a contingent deferred sales charge or "CDSC." The CDSC is deducted from your redemption proceeds. Under certain circumstances, the CDSC for Class C may be waived (such as certain redemptions from employer sponsored retirement plans). See "CDSC Waivers" under "Sales Charges" below. Class C shares pay distribution and service fees equal to 1.00% annually of average daily net assets. Orders for Class C shares of one or more Calvert funds will be refused when the total value of the purchase (including the aggregate market value of all Calvert fund shares held within the purchasing shareholder's account(s)) is $1 million or more. Investors considering cumulative purchases of $1 million or more should consider whether another Class of shares would be more appropriate and consult their financial intermediary. The Fund no longer accepts direct purchases of Class C shares by accounts for which no broker-dealer or other financial intermediary is specified. Any direct purchase received by the Fund's transfer agent for Class C shares for such accounts will automatically be invested in Class A shares. In addition, Class C shares held in an account for which no financial intermediary is specified and which are not subject to a CDSC will periodically be converted to Class A shares.

**Class I shares** are offered to clients of financial intermediaries who (i) charge such clients an ongoing fee for advisory, investment, consulting or similar services, or (ii) have entered into an agreement with the principal underwriter to offer Class I shares through a no-load network or platform. Such clients may include individuals, corporations, endowments, foundations and employer sponsored retirement plans. Class I shares may also be available through brokerage platforms of broker-dealer firms that have agreements with the Fund's principal underwriter to offer Class I shares solely when acting as an agent for the investor. An investor acquiring Class I shares through such platforms may be required to pay a commission and/or other forms of compensation to the broker. Class I shares are also offered to investment and institutional clients of CRM and its affiliates, and certain persons affiliated with CRM (including employees, officers and directors of CRM's affiliates). Class I shares do not pay distribution or service fees.

**Payments to Financial Intermediaries.** In addition to payments disclosed under "Sales Charges" below, the principal underwriter, out of its own resources, may make cash payments to certain financial intermediaries (which may include affiliates of the principal underwriter and investment adviser) who provide marketing support, transaction processing and/or administrative services and, in some cases, include some or all Calvert funds in preferred or specialized selling programs. Payments made by the principal underwriter to a financial intermediary may be significant and are typically in the form of fees based on Fund sales, assets, transactions processed and/or accounts attributable to that financial intermediary. Financial intermediaries also may receive amounts from the principal underwriter in connection with educational or due diligence meetings that include information concerning Calvert funds. The principal underwriter may pay or allow other promotional incentives or payments to financial intermediaries to the extent permitted by applicable laws and regulations.

Certain financial intermediaries that maintain fund accounts for the benefit of their customers provide sub-accounting, recordkeeping and/or administrative services to the Calvert funds and are compensated for such services by the funds. As used in this Prospectus, the term "financial intermediary" includes any broker, dealer, bank (including bank trust departments), registered investment adviser, financial planner, a retirement plan and/or

------

##### [**Table of Contents**](#toc)
its administrator, their designated intermediaries and any other firm having a selling, administration or similar agreement with the principal underwriter or its affiliates.

**Sales Charges** 

**Class A Front-End Sales Charge.** Class A shares are offered at net asset value per share plus a sales charge that is determined by the amount of your investment. The current sales charge schedule is:

---

| | | | |
|:---|:---|:---|:---|
| Amount of Purchase | Sales Charge\*<br>as a Percentage of<br>Offering Price | Sales Charge<sup>\*</sup><br>as a Percentage of Net<br>Amount Invested | Dealer Commission<br>as a Percentage of<br>Offering Price |
| &nbsp;&nbsp;&nbsp;&nbsp; Less than $50,000 | 5.25% | 5.54% | 4.75% |
| &nbsp;&nbsp;&nbsp;&nbsp; $50,000 but less than $100,000 | 4.50% | 4.71% | 4.00% |
| &nbsp;&nbsp;&nbsp;&nbsp; $100,000 but less than $250,000 | 3.50% | 3.63% | 3.00% |
| &nbsp;&nbsp;&nbsp;&nbsp; $250,000 but less than $500,000 | 2.50% | 2.56% | 2.00% |
| &nbsp;&nbsp;&nbsp;&nbsp; $500,000 but less than $1,000,000 | 2.00% | 2.04% | 1.50% |
| &nbsp;&nbsp;&nbsp;&nbsp; $1,000,000 or more | 0.00\*\* | 0.00\*\* | TIERED\*\* |

---

<sup>\*</sup>Because the offering price per share, which includes the front-end sales charge, is rounded to two decimal places, the actual sales charge you pay on a purchase of Class A shares may be more or less than your total purchase amount multiplied by the applicable sales charge percentage.

<sup>\*\*</sup>No sales charge is payable at the time of purchase on investments of $1 million or more. The principal underwriter will pay a commission to financial intermediaries on sales of $1 million or more as follows: 1.00% on amounts of $1 million or more but less than $4 million; plus 0.50% on amounts of $4 million but less than $15 million; plus 0.25% on amounts of $15 million or more. A CDSC of 1.00% will be imposed on such investments (as described below) in the event of redemptions within 12 months of purchase.

**Reducing or Eliminating Class A Sales Charges.** Front-end sales charges on purchases of Class A shares may be reduced under the right of accumulation or under a statement of intention. To receive a reduced sales charge, you must inform your financial intermediary or the Fund at the time you purchase shares that you qualify for such a reduction. If you do not let your financial intermediary or the Fund know you are eligible for a reduced sales charge at the time of purchase, you will not receive the discount to which you may otherwise be entitled.

**Right of Accumulation.** Under the right of accumulation, the sales charge you pay is reduced if the current market value of your holdings in the Fund or any other Calvert fund (based on the current maximum public offering price) plus your new purchase total is $50,000 or more. Shares owned by you, your spouse and children under age twenty-one may be combined for purposes of the right of accumulation, including shares held for the benefit of any of you in omnibus or "street name" accounts. In addition, shares held in a trust or fiduciary account of which any of the foregoing persons is the sole beneficiary (including employer sponsored retirement plans and IRAs) may be combined for purposes of the right of accumulation. Shares purchased and/or owned in a SEP, SARSEP and SIMPLE IRA plan may be combined for purposes of the right of accumulation for the plan and its participants. You may be required to provide documentation to establish your ownership of shares included under the right of accumulation (such as account statements for you, your spouse and children or marriage certificates, birth certificates and/or trust or other fiduciary-related documents).

**Statement of Intention.** Under a statement of intention, purchases of $50,000 or more made over a 13-month period are eligible for reduced sales charges. Shares eligible under the right of accumulation (other than those included in employer sponsored retirement plans) may be included to satisfy the amount to be purchased under a statement of intention. Under a statement of intention, the principal underwriter may hold 5% of the dollar amount to be purchased in escrow in the form of shares registered in your name until you

------

##### [**Table of Contents**](#toc)
satisfy the statement or the 13-month period expires. A statement of intention does not obligate you to purchase (or the Fund to sell) the full amount indicated in the statement. If during the 13-month period you redeem any of the shares that you purchased pursuant to the statement of intention, the value of the redeemed shares will not be included for purposes of satisfying your statement of intention. For additional information about statements of intention, see "Sales Charges" in the SAI.

Class A shares are offered at net asset value (without a sales charge) to accounts of clients of financial intermediaries who (i) charge an ongoing fee for advisory, investment, consulting or similar services, or (ii) have entered into an agreement with the principal underwriter to offer Class A shares through a no-load network or platform, or self-directed brokerage accounts that may or may not charge transaction fees to customers; or (iii) employer sponsored retirement plans. Class A shares also are offered at net asset value to investment and institutional clients of CRM and its affiliates; certain persons affiliated with CRM; direct purchases of shares by accounts where no financial intermediary is specified; and to certain fund service providers as described in the SAI. Class A shares are also offered at net asset value to shareholders who make a permitted direct transfer or roll-over to a Calvert prototype IRA from an employer-sponsored retirement plan previously invested in Calvert funds (applicable only to the portion previously invested in Calvert funds), provided that sufficient documentation is provided to the transfer agent of such transfer or roll-over at the time of the account opening. Class A shares may also be purchased at net asset value pursuant to the exchange privilege and when distributions are reinvested. A financial intermediary may not, in accordance with its policies and procedures, offer one or more of the waiver categories described above and shareholders should consult their financial intermediary for more information. The Fund may eliminate, modify or add to the terms of these sales charge waivers at any time without providing notice to shareholders.

**Contingent Deferred Sales Charge.** Class A and Class C shares are subject to a CDSC on certain redemptions. The CDSC generally is paid to the principal underwriter. Class A shares purchased at net asset value in amounts of $1 million or more are subject to a 1.00% CDSC if redeemed within 12 months of purchase. Class C shares are subject to a 1.00% CDSC if redeemed within 12 months of purchase. CDSCs are based on the lower of the net asset value at the time of purchase or at the time of redemption. Shares acquired through the reinvestment of distributions are exempt from the CDSC. Redemptions are made first from shares that are not subject to a CDSC.

The sales commission payable to financial intermediaries in connection with sales of Class C shares is described under "Distribution and Service Fees" below.

**CDSC Waivers.** CDSCs are waived for certain redemptions pursuant to a Withdrawal Plan (see "Shareholder Account Features") and in connection with certain redemptions from employer sponsored retirement plans or IRAs to satisfy required minimum distributions or to return excess contributions made to IRAs, if applicable. The CDSC is also waived following the death of a beneficial owner of shares (a death certificate and other applicable documents may be required). The CDSC on Class A and Class C shares will be waived in connection with sales of Class A and Class C shares for which no commission or transaction fee was paid by the Distributor or Financial Intermediary at the time of purchase of such shares.

**Conversion Feature.** Effective November 5, 2020 (the "Effective Date"), Class C shares of the Fund will convert automatically to Class A shares of the Fund during the month following the eight year anniversary of the purchase of such Class C shares. If a financial intermediary that maintains a Class C shareholder's account has not tracked the holding period for Class C shares, Class C shares held as of the Effective Date will automatically convert to Class A shares eight years after the Effective Date. In addition, Class C shares held in an account with the Fund's transfer agent for which no financial intermediary is specified and that are not subject to a CDSC will be converted to Class A shares of the Fund periodically.

In some circumstances, the Board may determine to cease to offer and subsequently close an existing class of Fund shares. In such circumstances, the Fund may automatically convert the shares for such class into another share class, subject to prior notice to shareholders of the impacted class. Any such conversion will occur at the respective net asset value of each class as of the conversion date without the imposition of any fee or other charges by the Fund.

------

##### [**Table of Contents**](#toc)
**Distribution and Service Fees.** Class A and Class C shares have in effect plans under Rule 12b-1 that allow the Fund to pay distribution fees for the sale and distribution of shares and service fees for personal and/or shareholder account services (so-called "12b-1 fees"). Class C shares pay distribution fees to the principal underwriter of 0.75% of average daily net assets annually. Because these fees are paid from Fund assets on an ongoing basis, they will increase your cost over time and may cost you more than paying other types of sales charges. The principal underwriter generally compensates financial intermediaries on sales of Class C shares (except exchange transactions and reinvestments) in an amount equal to 1.00% of the purchase price of the shares. After the first year, such financial intermediaries also receive 0.75% of the value of outstanding Class C shares sold by such financial intermediaries in annual distribution fees. With respect to purchases of Class C shares by certain employer sponsored retirement plans, the principal underwriter does not compensate the financial intermediary at the time of sale. In such cases, the financial intermediary receives 0.75% of the value of outstanding Class C shares sold by such financial intermediary in annual distribution fees immediately after the sale. Class C shares also pay service fees to the principal underwriter equal to 0.25% of average daily net assets annually. Class A shares pay distribution and service fees equal to 0.25% of average daily net assets annually. After the sale of Class A shares, the principal underwriter receives the Class A distribution and service fees and generally the financial intermediary receives such fees immediately after the sale. After the sale of Class C shares, the principal underwriter generally receives the Class C service fees for one year, thereafter financial intermediaries generally receive such fees. With respect to purchases of Class C shares by certain employer sponsored retirement plans, the financial intermediary also receives the above described service fees from the principal underwriter immediately after the sale. Such amounts are generally paid to financial intermediaries by the principal underwriter based on the value of shares sold by such financial intermediaries for shareholder servicing performed by such intermediaries. Distribution and service fees are subject to the limitations contained in the sales charge rule of the Financial Industry Regulatory Authority, Inc.

**More information about Fund sales charges is available free of charge on the Calvert website at www.calvert.com and in the SAI. Please consult the Calvert website for any updates to Fund sales charge information before making a purchase of Fund shares. Please consult your financial intermediary with respect to any sales charge variations listed on Appendix D-1.** 

**Redeeming Shares** 

You can redeem shares in any of the following ways:

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp; By Mail | Send your request to the transfer agent (see back cover for address). The request must be signed exactly as your account is registered (for instance, a joint account must be signed by all registered owners to be accepted) and a Medallion signature guarantee may be required. Circumstances that may require a Medallion signature guarantee include, but are not limited to, requests to distribute redemption proceeds to a party other than the registered account owner(s); requests to mail redemption proceeds to an address other than the address of record; requests to distribute proceeds to a bank account not on file; requests to re-issue uncashed checks representing redemption proceeds; or transaction requests from an account beneficiary when an account owner is deceased. You can obtain a Medallion signature guarantee at banks, savings and loan institutions, credit unions, securities dealers, securities exchanges, clearing agencies and registered securities associations that participate in The Securities Transfer Agents Medallion Program, Inc. (STAMP, Inc.). Only Medallion signature guarantees issued in accordance with STAMP, Inc. will be accepted. You may be asked to provide additional documents if your shares are registered in the name of a corporation, partnership or fiduciary. |
| &nbsp;&nbsp;&nbsp;&nbsp; By Telephone | Certain shareholders can redeem by calling 1-800-368-2745 Monday through Thursday, 9:00 a.m. to 5:30 p.m. (Eastern Time) and Friday, 9:00 a.m. to 5:00 p.m. (Eastern Time). Proceeds of a telephone redemption are generally limited to $100,000 per account (which may include shares of one or more Calvert funds) and can be sent only to the account address or to a bank pursuant to prior instructions. |

---

##### [**Table of Contents**](#toc)

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp; By Internet | Certain shareholders can redeem by logging on to the Calvert website at www.calvert.com. Proceeds of internet redemptions are generally limited to $100,000 per account (which may include shares of one or more Calvert funds) and can be sent only to the account address or to a bank pursuant to prior instructions. |
| &nbsp;&nbsp;&nbsp;&nbsp; For Additional Information | Please call 1-800-368-2745 Monday through Thursday, 9:00 a.m. to 5:30 p.m. (Eastern Time) and Friday, 9:00 a.m. to 5:00 p.m. (Eastern Time). |
| &nbsp;&nbsp;&nbsp;&nbsp; Through a Financial Intermediary | Your financial intermediary is responsible for transmitting the order promptly. A financial intermediary may charge a fee for this service. |

---

A redemption may be requested by sending a Medallion signature guaranteed letter of instruction to the transfer agent (see back cover for address) or, for telephone redemptions as described above, by calling 1-800-368-2745. Certain redemption requests, including those involving shares held by certain corporations, trusts or certain other entities and shares that are subject to certain fiduciary arrangements, may require additional documentation and may be redeemed only by mail. The Fund's transfer agent or your financial intermediary must receive your redemption in proper form (meaning that it is complete and contains all necessary information) no later than the close of regular trading on the NYSE (normally 4:00 p.m. Eastern Time) for your redemption to be effected at that day's net asset value. Redemption proceeds are reduced by the amount of any applicable CDSC and any federal income and state tax required to be withheld.

Redemption proceeds typically are paid to the redeeming shareholder in cash up to two business days after the redemption, but payment could take up to seven days, as permitted by the 1940 Act for the reasons discussed below. The actual number of days following receipt of a redemption request in which the Fund typically expects to pay redemption proceeds generally will depend on how you hold your shares with the Fund.

If your shares are held in a "street name" account with a financial intermediary (see "Shareholder Account Features—'Street Name' Accounts"), your intermediary will elect through National Securities Clearing Corporation ("NSCC") to settle redemptions either one business day or two business days after the redemption date and redemption proceeds normally will be wired to your financial intermediary on the settlement date pursuant to that election.

If your shares are held directly with the Fund's transfer agent, redemptions normally will be settled in one business day after the redemption date and redemption proceeds will be sent by regular mail on such date. However, if you have given proper written authorization in advance, you may request that redemption proceeds be wired on the settlement date directly to your bank account in any bank in the United States. While not currently charged by the Fund, you may be required to pay a wire transfer fee by your bank. If you request expedited mail delivery of your redemption proceeds and the Fund is able to accommodate your request, charges may apply. You may redeem all or a portion of the shares from your account on any day the Fund is open for business, provided the amount requested is not on hold or held in escrow pursuant to a statement of intention. When you purchase by check or with ACH funds transfer, the purchase will be on hold for up to 10 days from the date of receipt. During the hold period, redemption proceeds will not be sent until the transfer agent is reasonably satisfied that the purchase payment has been collected.

The Fund typically expects to meet redemption requests by (i) distributing any cash holdings, (ii) selling portfolio investments and/or (iii) borrowing from a bank under a line of credit. In addition to the foregoing, the Fund also may distribute securities as payment (a so-called "redemption in-kind"), in which case the redeeming shareholder may pay fees and commissions to convert the securities to cash. Unless requested by a shareholder, the Fund generally expects to limit use of redemption in-kind to stressed market conditions, but is permitted to do so in other circumstances. A shareholder who wishes to receive redemption proceeds in-kind must notify the Fund on or before submitting the redemption request by calling 1-800-368-2745. Securities distributed in a redemption in-kind would be valued pursuant to the Fund's valuation procedures and selected by the investment adviser. If a shareholder receives securities in a redemption in-kind, the shareholder could incur brokerage or other charges in

------

##### [**Table of Contents**](#toc)
converting the securities to cash and the value of such securities would be subject to price fluctuations until sold. There can be no assurance that the Fund will manage liquidity successfully in all market environments. As a result, the Fund may not be able to pay redemption proceeds in a timely fashion because of unusual market conditions, an unusually high volume of redemption requests or other factors. Additional information about redemptions in-kind, including the procedures for submitting such redemption requests, is contained in the Fund's SAI.

If your account value falls below $750, you may be asked either to add to your account or redeem it within 60 days. If you take no action, your account will be redeemed at net asset value and the proceeds sent to you.

**Shareholder Account Features** 

**Distributions.** You may have your Fund distributions paid in one of the following ways:

---

| | |
|:---|:---|
| **• Full Reinvest Option** | Distributions are reinvested in additional shares. *This option will be assigned if you do not specify an option.* |
| **• Partial Reinvest Option** | Dividends and short-term capital gains are paid in cash\* and long-term capital gains are reinvested in additional shares. |
| **• Cash Option** | Distributions are paid in cash.\* |
| **• Exchange Option** | Distributions are reinvested in additional shares of any class of another Calvert fund chosen by you, subject to the terms of that fund's prospectus. Before selecting this option, you must obtain a prospectus of the other fund and consider its objectives, risks, and charges and expenses carefully. |

---

\*If any distribution check remains uncashed for six months, CRM reserves the right to invest the amount represented by the check in Fund shares at the then-current net asset value of a Fund and all future distributions will be reinvested. For accounts held directly with a Fund's transfer agent for which the shareholder has elected to receive distributions via check, any distribution (dividend or capital gain) under $10.00 is automatically reinvested in additional shares regardless of your elected distribution option.

**Information about the Fund.** From time to time, you may receive the following:

<sup>○</sup> Semiannual and annual reports containing other information with respect to the Fund.

---

| | |
|:---|:---|
| <sup>○</sup> | Periodic account statements, showing recent activity and total share balance.  |

---

<sup>○</sup> Tax information needed to prepare your income tax returns.

---

| | |
|:---|:---|
| <sup>○</sup> | Proxy materials, in the event a shareholder vote is required.  |

---

<sup>○</sup> Special notices about significant events affecting your Fund.

Most fund information (including semiannual and annual reports, prospectuses and proxy statements) as well as your periodic account statements can be delivered electronically. For more information please go to www.calvert.com.

You may be contacted via mail, telephone or by electronic means by officers of the Fund, by personnel of the investment adviser or administrator, by the Fund's transfer agent, by broker-dealer firms, or by a professional solicitation organization in connection with a solicitation of proxies for a meeting of Fund shareholders.

The Calvert 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 provided below and additionally in the SAI. Such policies and procedures regarding disclosure of portfolio holdings are designed to prevent the misuse of material, non-public information about the funds.

The Fund will file information regarding its portfolio holdings with the SEC on its Form N-PORT. The Fund's Form N-CSR filings and certain information filed on Form N-PORT may be viewed on the SEC's website (www.sec.gov). The most recent fiscal quarter-end holdings may also be viewed on the Calvert website

------

##### [**Table of Contents**](#toc)
(www.calvert.com). Portfolio holdings information that is filed with the SEC is posted on the Calvert website approximately 60 days after the end of the quarter to which it relates. Portfolio holdings information as of each month end is posted to the website approximately one month after such month end. The Fund also posts information about certain portfolio characteristics (such as top ten holdings and asset allocation) at least quarterly on the Calvert website approximately ten business days after the period and the Fund may also post performance attribution as of a month end or more frequently if deemed appropriate.

**Withdrawal Plan.** You may redeem shares on a regular periodic basis by establishing a systematic withdrawal plan. Withdrawals will not be subject to any applicable CDSC if they are, in the aggregate, less than or equal to 12% annually of the greater of either the initial account balance or the current account balance. Because purchases of Class A shares are generally subject to an initial sales charge, Class A shareholders should not make withdrawals from their accounts while also making purchases.

**Exchange Privilege.** Each class of Fund shares may be exchanged for shares of the same Class of another Calvert fund. Exchanges are made at net asset value. If your shares are subject to a CDSC, the CDSC will continue to apply to your new shares at the same CDSC rate. For purposes of the CDSC, your shares will continue to age from the date of your original purchase of Fund shares Except as described below, any class of shares of a fund may be exchanged for any other class of shares of that fund, provided that the shares being exchanged are no longer subject to a CDSC and the conditions for investing in the other class of shares described in the applicable prospectus are satisfied. Class C shares are not permitted to be exchanged to Class A shares unless the CDSC has expired and the exchange is made to facilitate the shareholder's participation in a fee-based advisory program. See also Appendix B to this prospectus.

Before exchanging, you should read the prospectus of the new fund carefully. Exchanges are subject to the terms applicable to purchases of the new fund's shares as set forth in its prospectus. If you wish to exchange shares, write to the transfer agent (see back cover for address), log on to your account at www.calvert.com or call 1-800-368-2745. Periodic automatic exchanges are also available. The exchange privilege may be changed or discontinued at any time. You will receive at least 60 days' notice of any material change to the privilege. This privilege may not be used for "market timing" and may be terminated for market timing accounts or for any other reason. For additional information, see "Restrictions on Excessive Trading and Market Timing" under "Purchasing Shares." Ordinarily exchanges between different funds are taxable transactions for federal tax purposes, while permitted exchanges of one class for shares of another class of the same fund are not. Shareholders should consult their tax advisors regarding the applicability of federal, state, local and other taxes to transactions in Fund shares.

**Reinvestment Privilege.** If you redeem shares, you may reinvest at net asset value all or any portion of the redemption proceeds in the same account and in the same class of shares of the Fund you redeemed from or another Fund, provided that the reinvestment occurs within 90 days of the redemption, the privilege has not been used more than once in the prior 12 months, the redeemed shares were subject to a front-end sales charge or CDSC and that you are otherwise eligible to invest in that class. Under these circumstances your account will be credited with any CDSC paid in connection with the redemption. Any CDSC period applicable to the shares you acquire upon reinvestment will run from the date of your original share purchase. For requests for reinvestment sent to the Fund's transfer agent, the request must be in writing.

At the time of a reinvestment, you or your financial intermediary must notify the Fund or the transfer agent that you are reinvesting redemption proceeds in accordance with this privilege. If you reinvest, your purchase will be at the next determined net asset value following receipt of your request.

**Telephone and Electronic Transactions.** You can redeem or exchange shares by telephone as described in this Prospectus. In addition, certain transactions may be conducted through the Calvert website. The transfer agent and the principal underwriter have procedures in place to authenticate telephone and electronic instructions (such as using security codes or verifying personal account information). As long as the transfer agent and principal underwriter follow reasonable procedures, they will not be responsible for unauthorized telephone or electronic transactions and you bear the risk of possible loss resulting from these transactions. You may decline the

------

telephone redemption option on the account application. Telephone instructions are recorded. You should verify the accuracy of your confirmation statements immediately upon receipt and notify Calvert Shareholder Services of any inaccuracies.

**"Street Name" Accounts.** If your shares are held in a "street name" account at a financial intermediary, that intermediary (and not the Fund or its transfer agent) will perform all recordkeeping, transaction processing and distribution payments. Because the Fund does not maintain an account for you, you should contact your financial intermediary to make transactions in shares, make changes in your account, or obtain account information. You will not be able to utilize a number of shareholder features, such as telephone or internet transactions, directly with the Fund and certain features may be subject to different requirements. If you transfer shares in a "street name" account to an account with another financial intermediary or to an account directly with the Fund, you should obtain historical information about your shares prior to the transfer. If you fail to provide your full account history to your new financial intermediary following a transfer, you may be ineligible for certain features of the Fund.

**Procedures for Opening New Accounts.** To help the government fight the funding of terrorism and money laundering activities, federal law requires financial institutions to obtain, verify and record information that identifies each new customer who opens an account with the Fund and to determine whether such person's name appears on government lists of known or suspected terrorists or terrorist organizations. When you open an account, the transfer agent or your financial intermediary will ask you for your name, address, date of birth (for individuals), residential or business street address (although post office boxes are still permitted for mailing) and social security number, taxpayer identification number, or other government-issued identifying number. You also may be asked to produce a copy of your driver's license, passport or other identifying documents in order to verify your identity. In addition, it may be necessary to verify your identity by cross-referencing your identification information with a consumer report or other electronic databases. Other information or documents may be required to open accounts for corporations and other entities. Federal law prohibits the Fund and other financial institutions from opening a new account unless they receive the minimum identifying information described above. If a person fails to provide the information requested, any application by that person to open a new account will be rejected. Moreover, if the transfer agent or the financial intermediary is unable to verify the identity of a person based on information provided by that person, it may take additional steps including, but not limited to, requesting additional information or documents from the person, closing the person's account or reporting the matter to the appropriate federal authorities. If your account is closed for this reason, your shares may be automatically redeemed at the net asset value next determined. If the Fund's net asset value has decreased since your purchase, you will lose money as a result of this redemption. The Fund has also designated an anti-money laundering compliance officer.

**Account Questions.** If you have any questions about your account or the services available, please call Calvert Shareholder Services at 1-800-368-2745 Monday through Thursday, 9:00 a.m. to 5:30 p.m. (Eastern Time) and Friday, 9:00 a.m. to 5:00 p.m. (Eastern Time), or write to the transfer agent (see back cover for address).

**FINANCIAL INTERMEDIARY SALES CHARGE VARIATIONS** 

**Financial Intermediary Sales Charge Variations** 

*As noted under "Purchasing Shares," a financial intermediary may offer Fund shares subject to variations in or elimination of the Fund sales charges ("variations"), provided such variations are described in this Prospectus. Set forth below are the variations in sales charges applicable to shares purchased through the noted financial intermediary. All variations described below are applied by, and the responsibility of, the identified financial intermediary. Variations may apply to purchases, sales, exchanges and reinvestments of Fund shares and a shareholder transacting in Fund shares through the intermediary identified below should read the terms and conditions of the variations carefully. A variation that is specific to a particular financial intermediary is not applicable to shares held directly with the Fund or through another intermediary.* 

**Fund Purchases through Merrill Lynch** 

Purchases or sales of front-end (i.e. Class A) or level-load (i.e., Class C) mutual fund shares through a Merrill platform or account will be eligible only for the following sales load waivers (front-end, contingent deferred, or back-end waivers) and discounts, which differ from those disclosed elsewhere in this Fund's prospectus. Purchasers will have to buy mutual fund shares directly from the mutual fund company or through another intermediary to be eligible for waivers or discounts not listed below.

It is the client's responsibility to notify Merrill at the time of purchase or sale of any relationship or other facts that qualify the transaction for a waiver or discount. A Merrill representative may ask for reasonable documentation of such facts and Merrill may condition the granting of a waiver or discount on the timely receipt of such documentation.

Additional information on waivers and discounts is available in the Merrill Sales Load Waiver and Discounts Supplement (the "Merrill SLWD Supplement") and in the Mutual Fund Investing at Merrill pamphlet at ml.com/funds. Clients are encouraged to review these documents and speak with their financial advisor to determine whether a transaction is eligible for a waiver or discount.

**Breakpoints** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Breakpoint pricing, otherwise known as volume pricing, at dollar thresholds as described in the prospectus.

**Rights of Accumulation ("ROA")** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The applicable sales charge on a purchase of Class A shares is determined by taking into account all
share classes (except certain money market funds and any assets held in group retirement plans) of the mutual fund family held by the shareholder or in an account grouped by Edward Jones with other accounts for the purpose of providing certain
pricing considerations ("pricing groups"). If grouping assets as a shareholder, this includes all share classes held on the Edward Jones platform and/or held on another platform. The inclusion of eligible fund family assets in the ROA
calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Money market funds are included only if such shares were sold with a sales charge at the time of purchase or acquired in exchange for
shares purchased with a sales charge.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The employer maintaining a SEP IRA plan and/or SIMPLE IRA plan may elect to establish or change ROA for the
IRA accounts associated with the plan to a plan-level grouping as opposed to including all share classes at a shareholder or pricing group level.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ROA is determined by calculating the higher of cost minus redemptions or market value (current shares x NAV).

**Letter of Intent ("LOI")** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Through a LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders
intend to make over a 13-month period from the date Edward Jones receives the LOI. The LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in
combination with the value that the shareholder intends to buy over a 13-month period to calculate the front-end sales charge and any breakpoint discounts. Each purchase
the shareholder makes during that 13-month period will receive the sales charge and breakpoint discount that applies to the total amount. The inclusion of eligible fund family assets in the LOI calculation is
dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Purchases made before the LOI is received by Edward Jones are not adjusted under the LOI and will not reduce the sales charge previously paid. Sales
charges will be adjusted if LOI is not met.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If the employer maintaining a SEP IRA plan and/or SIMPLE IRA plan has elected to establish or change ROA for
the IRA accounts associated with the plan to a plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer.

**Sales Charge Waivers** 

Sales charges are waived for the following shareholders and in the following situations:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Associates of Edward Jones and its affiliates and other accounts in the same pricing group (as determined by
Edward Jones under its policies and procedures) as the associate. This waiver will continue for the remainder of the associate's life if the associate retires from Edward Jones in good-standing and remains in good standing pursuant to Edward
Jones' policies and procedures.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Shares purchased in an Edward Jones fee-based program.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Shares purchased through reinvestment of capital gains distributions and dividend reinvestment.

**SUPPLEMENTAL FINANCIAL INFORMATION** 

Rule 6-11(d)(2) under Regulation S-X requires that, with respect to any fund acquisition, registered investment companies must provide certain supplemental financial information in lieu of *pro forma* financial statements required by Regulation S-X. For this reason, *pro forma* financial statements of the Acquiring Fund are not included in this SAI.

Tables showing the fees of the Acquired Fund and the Acquiring Fund, and the fees and expenses of the Acquiring Fund on a *pro forma* basis after giving effect to the Merger, are included in the "Comparison of Fees and Expenses" section of the Information Statement/Prospectus.

The Merger will not result in a material change to the investment portfolio of the Acquired Fund due to the investment restrictions of the Acquiring Fund. As a result, a schedule of investments of each of those Funds modified to show the effects of the change is not required and is not included. Notwithstanding the foregoing, changes may be made to the Acquired Fund's portfolio in advance of the Merger and/or the Acquiring Fund's portfolio following the Merger, as described in the Information Statement/Prospectus.

There are no material differences in accounting policies of the Acquired Fund as compared to those of the Acquiring Fund.
