Fund profile
As filed in the prospectus · 2026 Q2
Columbia Small Cap Index Fund (the Fund) seeks total return before fees and expenses that corresponds to the total return of the Standard & Poors (S&P) SmallCap 600 Index.
The fund tracks the S&P SmallCap 600 Index by holding common stocks in approximately the same weightings as the Index, aiming for at least 95% correlation to its performance before fees and expenses. The fund may operate as non-diversified when the Index is non-diversified, allowing it to invest a greater percentage of assets in fewer issuers than a diversified fund would permit. Because the fund's weightings depend on the Index composition, performance may diverge from the Index if weightings drift between rebalancing periods.

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 |
|---|---|---|---|---|---|
| +38.42% | +51.41% | +31.88% | 13.54% | -19.85% | |
| +38.71% | +52.51% | +33.51% | 13.50% | -19.76% | |

| +38.64% | +52.53% | +33.51% | 13.53% | -19.74% |
These classes hold the same portfolio, so the 1.65pp spread over 5 years is the cost difference between them — roughly 0.33pp a year — not a difference in what they own.
May 2026 has been filed since the trailing figures were struck, so it is not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
