Calvert Research and Management (“Calvert”) and its advisory affiliates represent the investment management division of Morgan Stanley, a publicly held company (“Morgan Stanley”). Calvert is a Massachusetts business trust formed in August 2016 as a wholly-owned subsidiary of Eaton Vance Management (“Eaton Vance”). Eaton Vance is a wholly- owned subsidiary of Morgan Stanley. EV LLC serves as the trustee of Calvert and is a wholly-owned subsidiary of Morgan Stanley, a corporation whose shares are publicly held and traded on the New York Stock Exchange under the symbol “MS”. Morgan Stanley is a leading global financial services firm providing investment banking, securities, wealth management and investment management services. With offices in more than 41 countries, the Firm’s employees serve clients worldwide including corporations, governments, institutions, and individuals. Overview Calvert offers actively managed, passively managed, optimized, and model-only investment advisory services that include (but are not limited to) a variety of responsible investment equity, fixed- and floating-rate income, and multi-asset strategies. Calvert’s actively managed advisory service seeks to outperform one or more indices and/or peer groups by actively selecting investment opportunities. Calvert’s passively managed advisory service seeks to track the performance of one of the Calvert Responsible or Research Indexes (as defined herein). Calvert’s optimized strategies use environmental, social, and governance (“ESG”) factors along with traditional research and metrics which are then optimized to a particular index. Calvert also serves as investment adviser to certain mutual funds that seek to replicate third-party sponsored indices and do not use Calvert’s ESG research. An index is an unmanaged group of securities selected to replicate the aggregate performance of a particular market or group of securities. An investor cannot invest directly in an index. The majority of the investment mandates that Calvert manages for its clients (as defined below under “Clients”) include ESG analysis, performed by Calvert’s ESG research analysts. The research generated by Calvert is provided to certain affiliates of Calvert and can be utilized in the portfolio management process of such affiliates. Calvert generally analyzes investments using The Calvert Principles for Responsible Investment (the “Calvert Principles”) as a framework, as described on the company’s website (www.calvert.com) and in the description found in each applicable fund’s prospectus. Funds Calvert serves as the investment adviser to registered investment companies (each a “Fund” and collectively the “Calvert Funds” or “Funds”). The Calvert Funds have separate series or portfolios. Calvert either manages each portfolio directly or engages one or more sub-advisers, including Calvert’s affiliates, to manage all or a portion of a portfolio. The portfolios are open-end mutual funds that are sold to retail and institutional investors, except in the case of the variable funds, which are sold to qualified retirement plans and life insurance companies for allocation to their separate accounts. Certain of the variable funds advised by Calvert seek to replicate third-party sponsored indices and do not use Calvert’s ESG research. It is anticipated that Calvert will provide investment advisory services to additional types of funds in the future. Separate Accounts Calvert provides investment advisory services through separately managed accounts to institutional clients (“Institutional Accounts”), such as charitable organizations, corporations, family offices, and retirement plans. The advisory services for these accounts are tailored to each client based on its individual investment objectives. Before establishing an Institutional Account, Calvert and the client discuss the available investment strategies and the client’s investment objectives. Investment in certain securities or types of securities can be restricted at the request of the client. See Appendix A – Fee Schedules for a list of strategies offered for Institutional Accounts. FORM ADV, PART 2A CALVERT RESEARCH AND MANAGEMENT5 Wrap Fee and Platform Programs Our investment advisory services

are available through various bundled “wrap fee” programs (“Wrap Fee Programs”) sponsored by certain broker-dealers and/or investment advisers (“Sponsor(s)”), including an affiliate of Calvert, to individual investors, including high net worth and other retail investors. As used herein, the term Sponsor includes overlay managers to the extent a Wrap Fee Program utilizes an overlay manager. Clients that participate in these Wrap Fee Programs enter into a single agreement with the applicable Sponsor for our advisory services, as well as other bundled services. For a single “wrap” fee (which is paid to the Sponsor and the Sponsor then pays to us) the Sponsors offer our investment advisory services to their separately managed account clients and are generally, depending on the program, primarily responsible for: i. Monitoring and evaluating our performance; ii. Executing client portfolio transactions typically without additional commission charge (except that the client will be charged an added commission charge if we use a broker other than the Sponsor to execute trades); iii. Providing custodial services for clients’ assets; iv. Ensuring adherence to client guidelines, restrictions and/or client instructions; and/or v. Providing tax management services. We participate in certain Wrap Fee Programs pursuant to which we provide the Sponsors with a model portfolio that represents the securities we recommend in accordance with a particular investment strategy (the “Model Portfolio”). In most instances, we will communicate our recommendations comprising the Model Portfolio, and any changes thereto, to the Sponsors, who serve as investment advisers to the Wrap Fee Program clients and are responsible for implementation of any client-specific investment restrictions and for determining the suitability of our investment strategy for the client. In most instances, unless otherwise agreed, the Sponsor will exercise investment discretion with respect to securities that are purchased or sold for clients of such Model Portfolio Wrap Fee Programs and will be responsible for executing trades and seeking best execution for such Wrap Fee Program accounts. In addition to offering our advisory services through Wrap Fee Programs in the manner described above, certain separately managed accounts are offered to retail investors through what’s known as “dual contract arrangements” (a client will pay the Sponsor a fee and will also pay Calvert an advisory fee) in which a Sponsor and its client enter into an agreement with regard to the Sponsor’s overall management of the client’s assets pursuant to which the Sponsor identifies managers that offer particular strategies or products that the Sponsor believes are suitable for each client. Either the Sponsor or the client then selects the particular strategy or product and the applicable manager to manage portions of the client’s portfolio. In a “dual contract” arrangement, Calvert generally has separate agreements with the Sponsor and each applicable client, the latter of which outlines the scope and limitations of the advisory relationship between Calvert and the client. In such arrangements, the Sponsor, who itself has a client relationship with the client, and/or the client are generally responsible for determining whether a strategy offered by Calvert is suitable and appropriate for the client based on its investment objectives, risk tolerance and financial situation. Under these arrangements, the client can impose restrictions on investing in certain securities through the Sponsor or Calvert, if applicable. For further discussion on the impacts of restrictions on trading, please refer to Item 12 – Brokerage Practices, “Directed, Restricted or Constrained Brokerage Arrangements; Wrap Fee Programs”. Further Information For additional information regarding the specific investment strategies we employ please refer to Item 8, Methods of Analysis, Investment Strategies and Risk of Loss.
