Calvert US Mid-Cap Core Responsible Index. The Index is composed of the common stocks of mid-size companies that operate their businesses in a manner consistent with The Calvert Principles for Responsible Investment (the “Calvert Principles”). Mid-size companies are selected from the 1,000 largest publicly traded U.S. companies based on market capitalization, excluding business development companies and approximately the 200 largest publicly traded U.S. companies. The Calvert Principles serve as a framework for considering environmental, social and governance (“ESG”) factors. Stocks are weighted in the Index based on their float-adjusted market capitalization within the relevant sector, subject to certain prescribed limits. The Index is owned by CRM, which also serves as investment adviser to the Fund. Christopher Madden, CFA, Co-Head of Applied Responsible Investment Solutions, and Zi Ye, Index Manager, manage the Index construction process at CRM.

As of December 31, 2023, the Index included 614 companies, and the market capitalization ranged from approximately $1.2 billion to $55.6 billion with a weighted average market capitalization of $20.6 billion. Market capitalizations of companies within the Index are subject to change. The number of companies in the Index will change over time due to CRM’s evaluation of an issuer relative to the Calvert Principles or corporate actions involving companies in the Index. The Index is reconstituted annually and is rebalanced quarterly.
