If the Fund is a Feeder Fund, reflect the aggregate expenses of the Feeder Fund and the Master Fund in a single fee table using the captions provided. In a footnote to the fee table, state that the table and Example reflect the expenses of both the Feeder and Master Funds. If the prospectus offers more than one Class of a Multiple Class Fund or more than one Feeder Fund that invests in the same Master Fund, provide a separate response for each Class or Feeder Fund.  Base the percentages of "Annual Fund Operating Expenses" on amounts incurred during the Fund's most recent fiscal year, but include in expenses amounts that would have been incurred absent expense reimbursement or fee waiver arrangements. If the Fund has changed its fiscal year and, as a result, the most recent fiscal year is less than three months, use the fiscal year prior to the most recent fiscal year as the basis for determining "Annual Fund Operating Expenses."</ElementDefenition><ElementReferences>Reference 1: 1

The Fund invests in common stocks included in the Standard &amp;#038; Poor&amp;#8217;s 500 Index (S&amp;#038;P 500 or the Index). The S&amp;#038;P 500 is made up primarily of large-capitalization companies that represent a broad spectrum of the U.S. economy. Under normal market conditions, the Fund will invest at least 80% (including the amount of any borrowings for investment purposes) of its net assets in securities that are contained in the S&amp;#038;P 500.&lt;/p&gt;&lt;p&gt;The Fund follows a passive or indexing investment approach in an attempt to mirror the performance of the Index. Keep in mind that the Fund has operating expenses and transaction costs, while the Index does not. This means that, while the Fund may track the Index closely, it is typically unable to match the performance of the Index exactly. While there is no guarantee, the investment manager, Columbia Management Investment Advisers, LLC, expects the correlation between the Fund and the Index to be at least 0.95. A correlation of 1.00 means the return of the Fund can be completely explained by the return of the Index.&lt;/p&gt;</NonNumbericText><NonNumericTextHeader /><FootnoteIndexer /><CurrencyCode /><CurrencySymbol /><IsIndependantCurrency>false</IsIndependantCurrency><ShowCurrencySymbol>false</ShowCurrencySymbol><DisplayDateInUSFormat>false</DisplayDateInUSFormat><hasSegments>false</hasSegments><hasScenarios>false</hasScenarios></Cell></Cells><OriginalInstanceReportColumns /><Unit>Other</Unit><ElementDataType>us-types:textBlockItemType</ElementDataType><SimpleDataType>string</SimpleDataType><ElementDefenition>Principal investment strategies of the Fund.
