Investment objective & strategy

As of June 26, 2025 · prospectus

Objective. 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.

Strategy. Under normal circumstances, the Fund invests at least 80% of its net assets (including the amount of any borrowings for investment purposes) in common stocks that comprise the S&P SmallCap 600 Index (the Index). The Fund may invest in derivatives, such as futures (including equity index futures), for cash equitization purposes. Different common stocks have different weightings in the Index, depending on the amount of stock outstanding and the stocks current price. In seeking to match the performance of the Index, Columbia Management Investment Advisers, LLC (the Investment Manager) attempts to allocate the Funds assets among common stocks in approximately the same weightings as the Index. This is referred to as a passive or indexing approach to investing.

The Fund attempts to achieve at least a 95% correlation between the performance of the Index and the Funds investment results, before fees and expenses.
