Fund profile
As filed in the prospectus · 2026 Q1
The Funds investment objective is to seek to track the performance of the Calvert US Large-Cap Core Responsible Index (the Index), which measures the investment return of large-capitalization stocks.
The fund tracks the Calvert US Large-Cap Core Responsible Index using a replication method, holding the common stocks of large-capitalization U.S. companies that meet environmental, social, and governance criteria under the Calvert Principles, weighted by float-adjusted market capitalization. Because the fund is subject to regulatory diversification and concentration limits that the Index is not, its holdings may materially deviate from the Index it seeks to track.

Portfolio growth profile
How much of the fund’s stock holdings are in fast-growing companies · as of 2026 Q2
Share of the fund’s equity (by value) in companies whose trailing five-year revenue — or net-income — growth ranks in the top 25% of U.S. public companies. Foreign and newly-listed holdings are excluded, so the figure covers only part of the book. From SEC filings — not investment advice. How we measure this.

Return profile
Total return as filed — price change plus distributions reinvested · trailing figures to Apr 2026
| Share class | 1-year | 3-year | 5-year | Vol | Worst fall |
|---|---|---|---|---|---|
| +31.18% | +77.66% | +70.96% | 14.58% | -9.66% | |

| +31.60% | +79.28% | +73.60% | 14.60% | -9.59% |
These classes hold the same portfolio, so the 8.89pp spread over 5 years is the cost difference between them — roughly 1.78pp a year — not a difference in what they own.
May 2026 and Jun 2026 have been filed since the trailing figures were struck, so they are not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
